Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, abilityField technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, butAs long as all by the protection of Patent Law in the scope of the claims of the utility model.
Embodiment 1 includes as shown in Figure 1 and Figure 2 and Figure 3 vehicle frame 1, connection frame 3 and pedal assembly 2.Connection frame 3 includesThe bottom plate 34 that extends in the horizontal direction and the side plate 1 and side plate 2 32 for being connected to 34 two sides of bottom plate vertically.Side plate 1 and sideThe height of plate 2 32 is different, the height value height side plate 2 32 of side plate 1.The company of offering on side plate 1 and side plate 2 32Connect hole 33.
Pedal assembly 2 includes plate body 21, shaft 24 and the intermediate piece 23 for connecting plate body 21 and shaft 24.Wherein, shaft 24Both ends are rotatably installed in connecting hole 33.
Rotation stressed plate 25 is connected in shaft 24, there are driving devices 5, and in the present embodiment, driving device 5 is gasSpring can provide the tractive force of consistent.The upper end of gas spring and the upper part of side plate 1 are hinged, under gas springEnd and rotation stressed plate 25 are hinged, and in the case where the traction of gas spring is flexible, driving rotation stressed plate 25 is overturn, to drive shaft 24It is connected with plate body 21.
In actual operation, the model that can customize and replace gas spring according to customer demand, to provide different sizeTractive force.This is because in portioned product, need be after user leaves plate body 21 need 21 automatic turning of plate body, andIn other products, after needing user to leave plate body 21, plate body 21 is assisted to turn over to 21 1 upward power of plate body with foot or handGo back to position.
Plate body 21 is equipped with plate pad 22, and plate pad 22 is equipped with multiple evaginations and prism 221 made of elastic material.PrismOn the one hand 221 increase frictional force, anti-skidding, on the other hand during plate body 21 turns over, protect plate body 21 not by other componentCollision, protect equipment.
As shown in figure 3, intermediate piece 23 is connected to plate body 21 and shaft 24, the intelligence of transmission and main stressed member carryEnergy.
Intermediate piece 23 includes the socket part 231, connection socket part 231 and curved curve transition portion of connection shaft 24It 232 and is connect with curve transition portion 232 and straight interconnecting piece 233 that linearly direction extends, straight interconnecting piece 233 and plate body 21Connection.
Wherein, socket part 231 is in circular ring shape, is socketed in shaft 24, and operator stands on plate body 21, and straight companySocket part 233 takes a very big depth insertion plate body 21 to connect, and as main supporting part, curve transition portion 232 is at thisBetween two components, optimizes Impact direction, optimize rotary force provided by the gas spring of overturning.
As shown in Figure 1, being equipped with bottom plate 34 between side plate 1 and side plate 2 32, bottom plate 34 is equipped with logical for fixing piece 4The mounting hole crossed, the connection frame 3 are fixed by the fixing piece 4 and vehicle frame 1.Fixing piece 4 can be screw.User can lead toIt crosses screw bottom plate 34 is fixed on vehicle frame 1, so that entire pedal structure is all fixed with vehicle frame 1, connection type is simple and fast.
In the present embodiment, also comprising lower elastic contradictory piece 6, as shown in Figures 2 and 3, lower elasticity contradictory piece 6 can be twoIt is a or multiple, it contradicts in the lower surface of intermediate piece 23.Specifically, elastic contradictory piece 6 may include linear elasticity part 61 under every setWith nonlinear elasticity part 62, spring is can be used in the former, and the elastic force and its deformational displacement amount provided is in a linear relationship.The latter Ke CaiWith elastic polyurethane column, the elastic force provided and its deformational displacement amount are in non-linear relation.Subscriber station pedal plate body 21After upper, plate body 21 is overturn, and corresponding fitting abutting portion 234 pushes on intermediate piece 23, under be pressed in lower elasticity contradictory piece 6, lower bulletProperty contradictory piece 6 elastic force is provided, one limit the flip angle of plate body 21, and two provide buffering for plate body 21, in order to moreGood limit avoids 21 transition of plate body from overturning, and centre is put into polyurethane support column in the spring.It is bonded abutting portion 234 and nonlinear elasticityProperty part 62 on subject plane 621 be bonded contradict.It is all designed for flat face the part of two components fitting.
When plate body 21 is flipped up in collapsed state, overturning locating part 7 will use.Overturn such as Fig. 2 institute of locating part 7Show, is mounted on side plate 2 32.Overturning locating part 7 includes to adjust bolt 71, and the screw-in that user can be convenient, which screws out, adjusts bolt71, so as to adjust its outer distance stretched out.When user leaves plate body 21, and entire plate body 21 turns over, can be supported with bolt 71 is adjustedLimit is completed in touching.
