[0020] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0021] The following describes the electric tricycle compartment buffer device according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0022] The electric tricycle compartment buffer device provided in the embodiment of the present invention can be applied to the connection between the compartment and the vehicle body. By reducing the impact caused by bumpy roads, the risk of desoldering or breaking between the compartment and the vehicle body is reduced, thereby ensuring the safety of passengers and cargo.

[0023] like Figures 1-3 As shown, the electric tricycle compartment buffer device of the embodiment of the utility model may include a body bottom plate 1, a compartment body 2, a shock-absorbing steel plate 3, a buffer mechanism 4, a connecting component 5 and an adjusting component 6.

[0024] The carriage body 2 is in contact with the vehicle body bottom plate 1 through the shock-absorbing steel plate 3 .

[0025] It can be understood that, under the action of the shock-absorbing steel plate 3 , a normal shock-absorbing and buffering effect can be achieved between the vehicle body bottom plate 1 and the vehicle body 2 .

[0026] The buffer mechanism 4 may include a slide bar 41 , meshing teeth 42 and a buffer assembly 43 .

[0027] It should be noted that the slide rods 41 described in the above embodiment are provided in two groups, while the meshing teeth 42 are provided in multiple groups and are evenly distributed on both sides of the slide rod 41. At the same time, four buffer assemblies 43 are provided, with two in each group, and are provided on both sides of the slide rod 41.

[0028] Among them, the sliding rod 41 is connected to the bottom end of the car body 2, the bottom end of the sliding rod 41 slides through the car body bottom plate 1, the meshing teeth 42 are fixedly connected to both sides of the sliding rod 41, the buffer assembly 43 is fixedly connected to the car body bottom plate 1, and the buffer assembly 43 is meshed with the meshing teeth 42.

[0029] Specifically, when the vehicle body floor 1 is bumped, the vehicle body 2 descends and, under the action of the slide rod 41 and the meshing teeth 42 , comes into contact with the buffer assembly 43 , and achieves a buffering effect under the action of the buffer assembly 43 .

[0030] The connecting assembly 5 is fixedly connected to the vehicle body bottom plate 1 , and the top of the connecting assembly 5 is hinged to the vehicle body 2 .

[0031] It is understandable that the carriage body 2 can be lifted from the vehicle body floor 1 by the connecting assembly 5 to facilitate unloading.

[0032] The adjustment assembly 6 is mounted on the front surface of the buffer assembly 43 .

[0033] It should be noted that the adjustment component 6 described in the above embodiment plays the role of adjusting the rotational friction of the buffer component 43, thereby reducing the vibration caused by bumps.

[0034] Specifically, in the actual operation process, after pulling goods or carrying people, the relevant personnel connect the car body 2 with the car body floor 1 through the connecting component 5, and under the action of the connecting component 5, the effect of facilitating unloading is achieved. At the same time, under the action of the shock-absorbing steel plate 3, the car body 2 is simply shock-absorbing on the car body floor 1. Subsequently, when the bumps are large, the slide rod 41 and the buffer component 43 sink, and under the action of the buffer component 43, the collision between the car body 2 and the car body floor 1 during sinking is reduced, thereby achieving the effect of reducing the buffer. Subsequently, under the action of the adjusting component 6, the friction force of the buffer component 43 during rotation can be adjusted to increase the consumption of force generated during bumps. By reducing the impact caused by bumpy roads, the risk of desoldering or breakage between the car body and the car body is reduced, thereby ensuring the safety of passengers and goods.

[0035] In one embodiment of the present invention, Figures 1-2 As shown, the buffer assembly 43 may include a mounting frame 431 , an auxiliary rod 432 , a shock absorber 433 , a connecting plate 434 and a resistance wheel 435 .

[0036] It should be noted that the auxiliary rod 432 and the shock absorber 433 described in the above embodiment are both provided with two groups.

[0037] The shock absorber 433 is fixedly connected with the vehicle body bottom plate 1, the bottom end of the auxiliary rod 432 penetrates through the shock absorber 433, the top end of the vehicle body bottom plate 1 is provided with a sliding hole 436 for sliding of the auxiliary rod 432, and the top end of the shock absorber 433 is fixedly connected with the mounting frame 431.

[0038] It can be understood that the mounting frame 431 and the auxiliary rod 432 are mounted under the action of the shock absorber 433, and the mounting frame 431 is conveniently sunk and lifted on the shock absorber 433 under the action of the auxiliary rod 432, so that the bending phenomenon of the shock absorber 433 during contraction is avoided.

[0039] The connecting plate 434 is fixedly connected with the mounting frame 431, the resistance wheel 435 is rolling connected with the connecting plate 434, the resistance wheel 435 is engaged with the meshing tooth 42, and the adjusting assembly 6 is installed on the connecting plate 434.

[0040] It should be noted that when the meshing tooth 42 sinks with the sliding rod 41, the force generated during sinking is offset under the action of the resistance wheel 435.

[0041] One side of the connecting plate 434 is fixedly connected with an auxiliary plate 44.

[0042] It should be noted that the auxiliary plate 44 described in the above embodiment plays a role of strengthening the connecting plate 434.

[0043] In an embodiment of the utility model, as shown in Figures 1-2 The connecting assembly 5 can include a sleeve 51, a sleeve rod 52, a hinged frame 53 and a spring 54.

[0044] As a possible case, a rubber block can be added between the sleeve rod 52 and the spring 54, and the rubber block abuts against the inner wall of the sleeve 51, so as to further increase the effect of consuming the buffering force.

[0045] The sleeve 51 is fixedly connected with the vehicle body bottom plate 1, the sleeve rod 52 is slidingly penetrated into the inside of the sleeve 51, the spring 54 is fixedly connected in the inside of the sleeve 51, the bottom end of the sleeve rod 52 is fixedly connected with the spring 54, and the top end of the sleeve rod 52 is hingedly connected with the carriage body 2 through the hinged frame 53.

[0046] Specifically, the spring 54 and the sleeve rod 52 are connected under the action of the sleeve 51, and the effect of connecting the carriage body 2 and lifting the carriage body 2 from the vehicle body bottom plate 1 can be realized through the hinged frame 53, and under the action of the spring 54, the tail end bending of the carriage body 2 when the carriage body 2 is jolted is conveniently avoided.

[0047] In one embodiment of the present invention, Figures 1-2 As shown, the adjustment assembly 6 may include an adjustment bolt 61 and a clamping plate 62 .

[0048] As a possibility, a ceramic sheet may be installed between the clamping plate 62 and the resistance wheel 435 to further increase the effect of consuming the buffering force.

[0049] The clamping plate 62 is connected to the connecting plate 434 , the adjusting bolt 61 passes through the connecting plate 434 and is threadedly connected to the clamping plate 62 , and the clamping plate 62 abuts against the resistance wheel 435 .

[0050] Specifically, by installing the adjusting bolt 61 , the friction between the clamping plate 62 and the resistance wheel 435 is increased, thereby consuming the bumpy and sinking force of the car body 2 .

[0051] In one embodiment of the present invention, Figures 1-2 As shown, a rubber plate 7 is fixedly connected to the inner bottom end of the sliding hole 436 , and the rubber plate 7 is disposed below the auxiliary rod 432 .

[0052] It can be understood that, under the action of the rubber plate 7 , the auxiliary rod 432 is prevented from hitting the inside of the sliding hole 436 and causing the sliding hole 436 to be penetrated.

[0053] In summary, the electric tricycle cabin buffer device of the embodiment of the utility model, under the action of the buffer mechanism and the shock-absorbing steel plate, can reduce the impact of bumpy roads on the cabin. By reducing the impact caused by bumpy roads, the risk of desoldering or fracture between the cabin and the body is reduced, thereby ensuring the safety of passengers and cargo.
