Description

Technical Field

[0001] This utility model belongs to the technical field of logistics and transportation, and in particular relates to a cage car with a buffer structure. Background Technology

[0002] In logistics transportation, cage carts are used as tools for transporting goods. For convenient storage, cage carts are often designed to be foldable. In existing cage carts, some are designed so that the frame folds towards the bottom plate, that is, the cage cart is horizontally flat after folding. However, this structure inevitably limits the height of the frame. For taller frames, the folding method is to fold the bottom plate towards the frame, that is, it is vertically flat after folding. However, since the bottom plate is not restricted, when unfolded, the bottom plate causes its own weight to rotate downwards. Under the movement of the heavy bottom plate, a loud collision sound often occurs, and the damage to the bottom plate is accelerated in the long run. Utility Model Content

[0003] The purpose of this invention is to provide a cage car with a buffer structure, which can slow down the turning speed of the bottom plate when unfolded, so as to reduce the impact when the bottom plate rotates into place and reduce noise.

[0004] Based on this, the present invention provides a cage car with a buffer structure, including a frame and a bottom plate disposed on the frame. The bottom plate can rotate relative to the frame to flip from a horizontal unfolded posture to a folded posture. A buffer member is also provided between the frame and the bottom plate to support the bottom plate and reduce the flipping speed of the bottom plate from the folded posture to the unfolded posture.

[0005] As described above, in a cage car with a buffer structure, one side of the bottom plate is hinged to the frame, and the buffer is located at the hinge.

[0006] As described above, in a cage car with a buffer structure, the buffer is an elastic element that abuts against the bottom of the base plate and is always pushed towards the folded posture.

[0007] As described above, a cage car with a buffer structure has outwardly extending hinged portions on both sides of the rear end of the bottom plate. The hinged portions are rotatably mounted to the frame via hinge shafts. The buffer is disposed on the hinged portions, with one end abutting against the frame and the other end serving as a support portion abutting against the bottom plate.

[0008] As described above, in a cage car with a buffer structure, the supporting part has an L-shaped structure that extends along the rear side of the bottom plate to the bottom surface of the bottom plate.

[0009] As described above, in a cage car with a buffer structure, the buffer element is a torsion spring.

[0010] As described above, in a cage car with a buffer structure, the rear end of the bottom plate has a recessed mounting position, and the hinge portion is located within the mounting position.

[0011] As described above, a cage-like vehicle with a buffer structure includes a rear door assembly, a left door assembly, and a right door assembly. The left and right door assemblies are hinged to both sides of the rear door assembly, and the bottom plate is hinged to the lower side of the rear door assembly. The rear door assembly, left door assembly, right door assembly, and bottom plate together form a storage space. When in the unfolded position, the bottom plate is horizontal and supported by the left and right door assemblies. When in the folded position, the bottom plate flips towards the rear door assembly, and both the left and right door assemblies flip towards the rear door assembly.

[0012] As described above, in a cage car with a buffer structure, the bottom of the left and right door groups is provided with a support plate extending towards the center, and the support plate together supports the bottom plate in the unfolded position.

[0013] Implementing the embodiments of this utility model has the following beneficial effects:

[0014] This utility model provides a cage car with a buffer structure. By adding a buffer component to support the bottom plate between the bottom plate and the frame, the bottom plate can be supported by the buffer component when it rotates from a folded position to a horizontal unfolded position, which greatly slows down the speed of its flipping. This reduces the impact when it reaches the position, reduces or even eliminates the noise caused by the impact, and at the same time provides better protection for the bottom plate and improves its service life. Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this embodiment of the utility model provides a cage cart with a buffer structure, including a frame 1 and a base plate 2 disposed on the frame 1. The base plate 2 can rotate relative to the frame 1 to flip from a horizontal unfolded posture to a folded posture. This solution can be applied to taller cage cart frames. When the entire cage cart is folded, both the frame and the base plate can be folded by rotation. However, since the goods are basically stacked on the base plate during use, a relatively thick structure is generally used to ensure support strength, resulting in an increase in its own weight. It is conceivable that during unfolding, its own weight will generate a large acceleration during the flipping process, thus generating a large impact.

[0023] In this design, to mitigate the impact, a buffer 3 is provided between the frame 1 and the base plate 2 to support the base plate 2 and slow down its rotation speed from a folded to an unfolded position. By adding a buffer between the base plate and the frame, the base plate is supported by the buffer when rotating from a folded to a horizontal unfolded position, greatly reducing its rotation speed. This reduces the impact upon reaching the desired position, lowers or even eliminates the noise generated by the impact, and provides better protection for the base plate, extending its service life.

[0024] Of course, the buffer 3 in this solution can be directly installed on the frame 1. Its position is between the folded posture and the horizontal unfolded posture of the base plate 2. It can also be lowered as the base plate 2 flips. It can be understood that when the base plate 2 flips downward, it first contacts the buffer 3 to offset the impact, thereby reducing the flipping speed.

[0025] In this embodiment of the invention, one side of the base plate 2 is hinged to the frame 1, and the buffer 3 is located at the hinge. Specifically, the buffer 3 is an elastic element that abuts against the bottom of the base plate 2 and always pushes towards the folded posture. Its structure is simple; the elastic buffer 3 supports the base plate 2, and the abutment always generates a force towards the folded posture, thereby achieving the aforementioned effect of slowing down the flipping speed. Preferably, the buffer 3 in this solution is a torsion spring. A good buffering effect can be achieved by setting a torsion spring with a suitable torque, without affecting the base plate 2 maintaining a horizontal posture. Taking the base plate 2 in a nearly vertical posture when folded as an example, during the flipping process to horizontal, the horizontal distance between the center of gravity of the base plate 2 and the hinge increases, causing the torque at the center of gravity to be greater than the effect of the elastic buffer 3, thus eliminating concerns about rebound.

[0026] Of course, the flexible buffer 3 in this design also provides assistance when the base plate 2 is turned into a folding position. When the base plate approaches the folding position, it is automatically positioned by the buffer 3, thus providing a certain degree of stability. This makes the base plate 2 more stable after folding.

[0027] Specifically, in this embodiment of the invention, the rear end of the base plate 2 has outwardly extending hinge portions 51 on both sides. The hinge portions 51 are rotatably mounted to the frame 1 via hinge shafts. The buffer member 3 is disposed on the hinge portions 51, with one end abutting against the frame 1 and the other end serving as a support portion 21 abutting against the base plate 2. Furthermore, the support portion 21 has an L-shaped structure, extending along the rear side of the base plate 2 to its bottom surface. Its L-shaped structure can adapt to the contour of the base plate and maintain contact with it.

[0028] Furthermore, the rear end of the base plate 2 has a recessed mounting position, and the hinge portion 51 is located within the mounting position. This ensures that the rear end of the base plate 2 will not be further away due to the outward-extending joint after installation, resulting in a more compact structure.

[0029] Specifically, in this embodiment of the present invention, the specific structure of the frame 1 is as follows: the frame 1 includes a rear door assembly 11, a left door assembly 12, and a right door assembly 13. The left door assembly 12 and the right door assembly 13 are hinged to both sides of the rear door assembly 11, and the bottom plate 2 is hinged to the lower side of the rear door assembly 11. The rear door assembly 11, the left door assembly 12, the right door assembly 13, and the bottom plate 2 together form a storage space. When the frame is unfolded, the bottom plate 2 is horizontal and supported by the left door assembly 12 and the right door assembly 13. When the frame is folded, the bottom plate 2 flips towards the rear door assembly 11, and the left door assembly 12 and the right door assembly 13 also flip towards the rear door assembly 11.

[0030] Furthermore, the bottom of the left door assembly 12 and the right door assembly 13 are provided with support plates 15 extending towards the center, and the support plates 15 together support the base plate 2 in the unfolded position. The function of the support plates 15 is to provide support, and they are also used to install casters.

[0031] This utility model provides a cage car with a buffer structure. By adding a buffer component to support the bottom plate between the bottom plate and the frame, the bottom plate can be supported by the buffer component when it rotates from a folded position to a horizontal unfolded position, which greatly slows down the speed of its flipping. This reduces the impact when it reaches the position, reduces or even eliminates the noise caused by the impact, and at the same time provides better protection for the bottom plate and improves its service life.

[0032] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
