[0063] Referring to FIG. Figures 2 to 10 The base 100 comprises a base plate 110 and two plate springs 120 limited above the base plate 110. The base plate 110 is fixed on the fixed frame 20, and the plate springs 120 are used for connecting the wheel frame 200. The plate springs 120 have elasticity, and the plate springs 120 can be elastically deformed, thereby driving the friction wheels 300 on the plate springs 120 to move.

[0064] A plurality of upper and lower penetrating fixing holes 111 are formed in the base plate 110; the lower surface of the base plate 110 is supported on the fixed frame 20; a fastener 112 is arranged between the fixing hole 111 and the fixed frame 20, and the fastener 112 is arranged in the fixing hole 111. The lower end of the fastener 112 is fixed on the fixed frame 20, thereby fixing the base plate 110 on the fixed frame 20.

[0065] In some embodiments, the fixing hole 111 extends in the first direction; thereby the position of the base plate 110 relative to the fixed frame 20 can be adjusted in the first direction, so as to adjust the position of the friction wheels 300 on the wheel frame 200 in the first direction, and ensure that the clamping plate 32 of the carrier plate 30 is located between the two friction wheels 300.

[0069] Figure 11 It is a structural schematic diagram of the leaf spring of the utility model.

[0070] Referring to Figures 3 to 11 The two leaf springs 120 are positioned on the bottom plate 110 and above the bottom plate 110, and the two leaf springs 120 are arranged opposite to each other in the first direction and can be elastically deformed in the first direction; the two leaf springs 120 extend in the second direction. The two wheel frames 200 are fixed on the two leaf springs 120 respectively, and the two leaf springs 120 can be elastically deformed in the first direction, so that the friction wheels 300 on the two wheel frames 200 can move relatively close to or away from each other in the first direction, so as to keep clamping the vehicle plate 30.

[0071] The length direction of the leaf spring 120 is along the second direction, one end of the leaf spring 120 is fixed on the bottom plate 110, and the other end is arranged on the bottom plate 110, so that the leaf spring 120 is more easily elastically deformed, and better adapts to the movement of the vehicle plate 30.

[0072] In some embodiments, the upper surface of the bottom plate 110 is formed with a protruding fixed column 114, and one end of the leaf spring 120 is fixed on the fixed column 114. One end of the leaf spring 120 is formed with a clamping hole 121, and the clamping hole 121 is sleeved on the fixed column 114, so that one end of the leaf spring 120 is fixed on the fixed column 114. The clamping hole 121 penetrates up and down, and one end of the leaf spring 120 is clamped on the fixed column 114 through the clamping hole 121, and the upper end of the fixed seat positions the leaf spring 120 on the fixed column 114 through a nut. For example, one end of the leaf spring 120 is wound to form the clamping hole 121.

[0073] In one embodiment, the fixed column 114 is formed with a step, and the lower end of the leaf spring 120 is made on the step, so that there is a gap between the lower end of the leaf spring 120 and the upper surface of the bottom plate 110.

[0074] In another embodiment, a reinforcing rib 117 is arranged between the fixed column 114 and the bottom plate 110, and the reinforcing rib 117 and the upper end form a step. The reinforcing rib 117 can not only play a role in reinforcing the fixed column 114, but also play a role in supporting the lower end of the leaf spring 120. The reinforcing rib 117 is arranged around the axis of the fixed seat.

[0075] In one embodiment, two leaf springs 120 are arranged in the first direction, and two fixed columns 114 are arranged on the bottom plate 110 to correspond to the two leaf springs 120, and the two leaf springs 120 are arranged in the first direction.

[0076] In this application, the upper surface of the bottom plate 110 is formed with a protruding support plate 115. One end of the leaf spring 120 is fixed on the fixed column 114, and the other end is arranged in the support plate 115. The leaf spring 120 is arranged in the support plate 115, so that the end of the leaf spring 120 arranged in the support plate 115 can move in the second direction, so as to facilitate the deformation of the leaf spring 120.

[0077] The support plate 115 is provided with a through hole 116; one end of the leaf spring 120 is arranged in the through hole 116; the through hole 116 has a preset length in the first direction, and the end of the leaf spring 120 arranged in the through hole 116 can move in the first direction within the through hole 116 by the preset length, so as to adapt to the position and movement of the carrier plate 30, and more effectively avoid the carrier plate 30 from being stuck.

[0078] The lower end of the leaf spring 120 and the upper surface of the bottom plate 110 have a gap. The lower edge of the through hole 116 and the upper surface of the bottom plate 110 have a gap, and after the leaf spring 120 is arranged in the through hole 116, the end of the leaf spring 120 arranged in the through hole 116 and the bottom plate 110 have a gap.

[0079] In some embodiments, the support plate 115 is provided with two through holes 116, and two leaf springs 120 are arranged in the two through holes 116 respectively. In another embodiment, the support plate 115 is provided with one through hole 116, and two leaf springs 120 are arranged in the same through hole 116.

[0080] In one embodiment, the upper end of the through hole 116 is open to facilitate the placement of the leaf spring 120 in the through hole 116. The upper end of the support plate 115 is provided with a detachable pressing plate 130, which is pressed on the upper end of the leaf spring 120 and closes the upper end of the through hole 116. The pressing plate 130 is fixed on the upper end of the support plate 115 by bolts.

[0081] The pressure plate 130 presses the leaf spring 120 downward onto the support plate 115. The pressure plate 130 also presses the leaf spring 120 downward onto the lower edge of the through hole 116 in the support plate 115, restricting the vertical movement of the leaf spring 120. The nut at the upper end of the fixing post 114 also serves to restrict the vertical movement of the plate.

[0082] A fixing member 140 connects the two leaf springs 120; the fixing member 140 is fixed to one end of the two leaf springs 120 that passes through the support plate 115. By fixing one end of the two leaf springs 120 with the fixing member 140, one end of the two leaf springs 120 is clamped, thereby ensuring that the two leaf springs 120 are clamped toward the support plate 115, and ensuring the clamping force or friction force on the vehicle platform 30.

[0083] After the fastener 140 clamps the two leaf springs 120, the ends of the two leaf springs 120 that pass through the through hole 116 slide along the first direction, and the clamping of the two leaf springs 120 is still guaranteed, thus ensuring the clamping force on the vehicle plate 30.

[0084] In one specific embodiment, the end of the leaf spring 120 facing the support plate 115 passes through the through hole 116 and is movable in a second direction within the through hole 116. The end of the leaf spring 120 facing the fixing post 114 is sleeved on the outside of the fixing post 114, and the leaf spring 120 is rotatable about the axis of the fixing post 114. The fixing member 140 is connected to the end of the leaf spring 120 facing the support plate 115 to maintain the positional relationship between the two leaf springs 120.

Figure 13 yes Figure 12 A schematic diagram of the structure from another perspective. Figure 14 This is a structural schematic diagram of the wheel frame of this utility model.

[0086] See Figures 2 to 14 Two wheel frames 200 are configured, each fixed to a leaf spring 120. Friction wheels 300 are respectively mounted on each wheel frame 200. The friction wheels 300 on the two wheel frames 200 are spaced apart along a first direction to clamp the vehicle platform 30 between the friction wheels 300 on the two wheel frames 200. The two leaf springs 120 can elastically deform in the first direction, allowing the friction wheels 300 on the two wheel frames 200 to move closer and further apart under the influence of the two wheel frames 200. The elasticity between the leaf springs 120 provides a clamping force for the friction wheels 300 on the vehicle platform 30. The elasticity between the two leaf springs 120 also allows the position of the friction wheels 300 on the two wheel frames 200 to automatically adjust to the vibration and deformation of the vehicle platform 30, effectively ensuring the smooth movement of the vehicle platform 30.

[0087] The friction wheels 300 are rotatably connected to the wheel frames 200 about the vertical axis, and the two friction wheels 300 rotate towards each other, thereby enabling the movement of the vehicle plate 30 in the second direction. The friction wheels 300 are rotatably connected to the corresponding wheel frames 200 by the rotating shafts 310.

[0088] In one embodiment, the driving unit 400 is drivingly connected to the friction wheels 300 on the two wheel frames 200, for driving the friction wheels 300 on the two wheel frames 200 to rotate towards each other. Thus, the driving force for moving the vehicle plate 30 is provided.

[0089] The friction wheels 300 are rotatably connected to the corresponding wheel frames 200 by the rotating shafts 310; the outer periphery of each rotating shaft 310 is fixed with a transmission gear 320; and the driving unit 400 is wound around and connected to all the transmission gears 320 by the chain 410.

[0090] In some embodiments, two friction wheels 300 are respectively arranged on each wheel frame 200, and the number of transmission gears 320 corresponds to the number of friction wheels 300. The two friction wheels 300 on the same wheel frame 200 are arranged in the second direction. The chain 410 is wound around the four transmission gears 320 on the two wheel frames 200, so that the two friction wheels 300 on the two wheel frames 200 can rotate towards each other.

[0091] In other embodiments, one or more friction wheels 300 are arranged on each wheel frame 200. For example, one, three, four or five friction wheels 300 are arranged on each wheel frame 200.

[0092] In one embodiment, the wheel frames 200 are fixed to the upper ends of the leaf springs 120. In another embodiment, the two wheel frames 200 are fixed to the opposite sides of the two leaf springs 120.
