Description

Technical Field

[0001] The utility model relates to the technical field of tricycle balance suspensions, and specifically, to a tricycle balance suspension. Background Art

[0002] Small tricycles usually adopt a balance suspension design different from that of four-wheel vehicles. The design purpose is to simplify the structure and reduce costs as much as possible while ensuring sufficient stability.

[0003] In real life, the carriage of a small tricycle is often fixedly connected to the frame, which results in extremely poor shock absorption performance of the small tricycle. However, considering the cost, it is not suitable to adopt a hydraulic shock absorption method. Therefore, a low-cost shock absorption method needs to be considered. At the same time, small tricycles are most likely to tip up when unloading goods, endangering the safety of people and vehicles.

[0004] Therefore, there is an urgent need to provide a tricycle balance suspension to solve the above problems. Summary of the Utility Model

[0005] In order to solve the problems that the existing tricycle balance suspension has weak shock absorption and is prone to tipping up during unloading, endangering the safety of people and vehicles, the utility model provides the following technical solutions: A tricycle balance suspension includes a suspension assembly. The suspension assembly includes a chassis and a bracket arranged on the chassis. A load-carrying assembly is arranged on the chassis, and the load-carrying assembly includes a cargo box.

[0006] Wherein, the suspension assembly further includes mounting plates symmetrically arranged at the tail of the chassis. The cargo box is movably connected to the chassis through the mounting plates. A support assembly is further arranged at the tail of the chassis to support the chassis and prevent it from tipping up. A shock absorption assembly is also arranged on the chassis to buffer the bumps of the cargo box. Through the coordinated cooperation of the support assembly, fixing assembly and shock absorption assembly, comprehensive optimization in aspects such as shock absorption, support, fixing and unloading is achieved. It not only improves the driving stability and safety of the tricycle, but also simplifies the unloading process and improves work efficiency, thereby effectively solving the problems that the existing tricycle balance suspension has weak shock absorption and is prone to tipping up during unloading, endangering the safety of people and vehicles.

[0007] As a further improvement of this technical solution, a chute is opened on the mounting plate. A limiting block is movably connected in the chute, and the limiting block is fixedly connected to one side of the tail of the cargo box; through the movable connection between the chute opened on the mounting plate and the limiting block at the tail of the cargo box, this design enables the cargo box to slide up and down during bumps in the transportation process, and at the same time, the limiting block plays a limiting role in the chute to ensure the stability of the cargo box. In addition, during unloading, the rotation of the limiting block in the chute facilitates the lifting of one end of the cargo box, thereby improving the convenience and efficiency of unloading.

[0008] As a further improvement of the technical solution, the support assembly includes a connecting rod rotatably connected to the tail of the chassis. A first torsion spring is provided at the connection between the connecting rod and the chassis. One end of the first torsion spring is fixedly connected to the chassis, and the other end is fixedly connected to the connecting rod. A first lead screw is fixedly provided at the bottom end of the connecting rod. The first lead screw is initially parallel to the chassis. A first sleeve is threadedly sleeved on the first lead screw. Diagonal support assemblies are symmetrically arranged on both sides of the first lead screw to increase the support stability of the chassis. A triangular support structure is jointly formed by the diagonal support assemblies on both sides of the first lead screw and the first sleeve. By including a connecting rod, a first lead screw, a first sleeve and a diagonal support assembly in the support assembly, by rotating the connecting rod and the first lead screw to form a support with the ground and combining with the diagonal support assembly to form a stable triangular support structure, effectively preventing the chassis from tilting up during unloading and ensuring the safety of personnel and vehicles.

[0009] As a further improvement of the technical solution, the diagonal support assembly includes a second lead screw rotatably connected to one side of the first lead screw. A second torsion spring is provided at the connection between the second lead screw and the first lead screw. One end of the second torsion spring is fixedly connected to the second lead screw, and the other end is fixedly connected to the second lead screw. A second sleeve is threadedly sleeved on the second lead screw. The diagonal support assembly is initially parallel to the first lead screw.

[0010] The first torsion spring always exerts a torsional force that makes the first lead screw tend to be parallel to the chassis, and the second torsion spring always exerts a torsional force that makes the second lead screw tend to be parallel to the first lead screw.

[0011] As a further improvement of the technical solution, the shock absorption assembly includes shock absorption plates symmetrically fixed on both sides of the chassis. The shock absorption plates are in an arc structure. A shock absorption spring is fixedly provided at the middle position of the shock absorption plates. The shock absorption spring is flush with the ends of both ends of the shock absorption plates. The shock absorption assembly uses shock absorption plates in an arc structure and shock absorption springs arranged therein. The two work together to provide a good buffering effect on the bumps of the cargo box during transportation, improving the driving smoothness and the safety of the goods.

[0012] As a further improvement of the technical solution, the fixing assembly includes a mounting seat fixed on the bracket. The mounting seat is arranged at one end of the bracket away from the support assembly. It also includes a lock fixed on the cargo box. A hook is rotatably connected to the mounting seat. A locking hook is rotatably connected to the hook. The locking hook matches the lock, and there is a movable space for the up and down movement of the cargo box between the lock and the locking hook.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] 1. The tricycle balance suspension can effectively absorb vibrations when encountering bumps by setting a shock-absorbing plate and a shock-absorbing spring, reducing the bump amplitude of the cargo box. Specifically:

[0015] The arc-shaped shock-absorbing plate and the shock-absorbing spring arranged in the middle of the shock-absorbing plate will play a role in buffering and shock absorption for the cargo box. Moreover, the shock-absorbing spring is arranged in the middle of the arc-shaped shock-absorbing plate, which can further improve the buffering effect on the cargo box.

[0016] 2. The tricycle balance suspension sets a support component including a connecting rod, a first lead screw, a first sleeve and a diagonal support component. By rotating the connecting rod and the first lead screw, it forms a support with the ground and combines with the diagonal support component to form a stable triangular support structure, effectively preventing the chassis from tipping up during unloading and ensuring the safety of personnel and vehicles.

[0017] 3. The tricycle balance suspension makes the cargo box stable during transportation by setting a limit block to cooperate with the chute on the mounting plate, and at the same time, it can conveniently move the cargo box during unloading, which is beneficial to rapid loading and unloading of goods, thus improving work efficiency.

[0018] Secondly, by setting a lock, a lock hook and a draw hook, the cargo box can be quickly fixed on the chassis and can also be quickly released during unloading, which is beneficial to saving loading and unloading time; using relatively low-cost components such as shock-absorbing plates and shock-absorbing springs not only reduces the cost of the entire system, but also ensures good shock-absorbing performance through reasonable structural design, which is beneficial to reducing production costs while ensuring performance.

[0036] In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" or "several" is two or more, unless otherwise specifically defined.

[0037] Please refer toFigures 1-7 As shown in the figure, the purpose of this embodiment is to provide a tricycle balance suspension, which includes a suspension assembly 1. The suspension assembly 1 includes a chassis 11 and a bracket 12 arranged on the chassis 11. A load-carrying assembly 2 is arranged on the chassis 11, and the load-carrying assembly 2 includes a cargo box 21.

[0038] Furthermore, the suspension assembly 1 further includes mounting plates 13 symmetrically arranged at the tail of the chassis 11. The cargo box 21 is movably connected to the chassis 11 through the mounting plates 13. A support assembly 4 is also arranged at the tail of the chassis 11 to support the chassis 11 and prevent it from tipping up. A shock-absorbing assembly 5 is also arranged on the chassis 11 to buffer the bumps of the cargo box 21.

[0039] Moreover, a chute 14 is formed on the mounting plate 13, and a limit block 22 is movably connected in the chute 14. The limit block 22 is fixedly connected to one side of the tail of the cargo box 21. In this way, during transportation, in case of bumps, when the cargo box 21 moves up and down due to the bumps, the limit block 22 slides up and down in the chute 14, and at the same time plays a role in limiting the cargo box 21. When unloading, the limit block 22 rotates in the chute 14, which is convenient for the end of the cargo box 21 far from the support assembly 4 to be lifted for unloading.

[0040] Specifically, the support assembly 4 includes a connecting rod 41 rotatably connected to the tail of the chassis 11. A first torsion spring 44 is arranged at the connection between the connecting rod 41 and the chassis 11. One end of the first torsion spring 44 is fixedly connected to the chassis 11, and the other end is fixedly connected to the connecting rod 41. A first lead screw 42 is fixedly provided at the bottom end of the connecting rod 41. The first lead screw 42 is parallel to the chassis 11 in the initial state. A first sleeve 43 is threadedly sleeved on the first lead screw 42. Diagonal support assemblies 45 are also symmetrically arranged on both sides of the first lead screw 42 to increase the support stability of the chassis 11. A triangular support structure is jointly formed by the diagonal support assemblies 45 on both sides of the first lead screw 42 and the first sleeve 43.

[0041] Furthermore, the diagonal support assembly 45 includes a second lead screw 451 rotatably connected to one side of the first lead screw 42. A second torsion spring 453 is arranged at the connection between the second lead screw 451 and the first lead screw 42. One end of the second torsion spring 453 is fixedly connected to the second lead screw 451, and the other end is fixedly connected to the second lead screw 451. A second sleeve 452 is threadedly sleeved on the second lead screw 451. The diagonal support assembly 45 is parallel to the first lead screw 42 in the initial state;

[0042] The first torsion spring 44 always exerts a torsional force that makes the first lead screw 42 tend to be parallel to the chassis 11, and the second torsion spring 453 always exerts a torsional force that makes the second lead screw 451 tend to be parallel to the first lead screw 42.

[0043] In addition, the shock absorption assembly 5 includes shock absorption plates 51 symmetrically fixed on both sides of the chassis 11. The shock absorption plates 51 are arc-shaped structures, and a shock absorber spring 52 is fixed at the middle position of the shock absorption plates 51. The shock absorber spring 52 is flush with the ends of both ends of the shock absorption plates 51.

[0044] In addition, the fixing assembly 3 includes a mounting seat 34 fixed on the bracket 12. The mounting seat 34 is arranged at one end of the bracket 12 away from the support assembly 4. It also includes a lock 31 fixed on the cargo box 21. A hook 33 is rotatably connected to the mounting seat 34, and a locking hook 32 is rotatably connected to the hook 33. The locking hook 32 matches the lock 31, and there is a moving space for the up and down movement of the cargo box 21 between the lock 31 and the locking hook 32.

[0045] The specific working principle is as follows:

[0046] After the cargo box 21 of the tricycle is loaded with goods, hook the locking hook 32 on the lock 31, and pull the hook 33 to rotate it to a vertical state to complete the fixing of the cargo box 21. It should be noted that there is a moving space for the up and down bumping of the cargo box 21 between the lock 31 and the locking hook 32;

[0047] During transportation, in case of bumps, the arc-shaped shock absorption plates 51 and the shock absorber springs 52 arranged in the middle of the shock absorption plates 51 will play a role in buffering and shock absorption for the cargo box 21. The shock absorption plates 51 are steel plates with arc-shaped structures, and both they and the shock absorber springs 52 are components with relatively low costs. The shock absorber springs 52 are arranged in the middle of the arc-shaped shock absorption plates 51, which can further improve the buffering effect on the cargo box 21;

[0048] When unloading is required, first rotate the connecting rod 41 to make the first lead screw 42 rotate until it is perpendicular to the chassis 11, and then rotate the first sleeve 43 until its bottom end fits the ground to support the chassis 11. At the same time, due to the friction force after the first sleeve 43 fits the ground, the first torsion spring 44 cannot drive the first lead screw 42 to reset; then rotate the second lead screws 451 on both sides of the first lead screw 42 to make the second lead screws 451 on both sides and the first sleeve 43 jointly form a triangular support structure, so that the support is more stable. Then rotate the second sleeve 452 to make it fit the ground. At this time, the support for the chassis 11 can be completed; then pull up the hook 33 to separate the locking hook 32 from the lock 31, and the cargo box 21 can be lifted from the end away from the support assembly 4, which is convenient for unloading.

[0049] Furthermore, it effectively solves the problems that the existing tricycle balance suspension has weak shock absorption and is prone to tipping up during unloading, endangering the safety of people and vehicles.

[0050] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present utility model, and are not used to limit the present utility model.
