Description

Technical Field

[0001] This utility model belongs to the field of luggage technology, specifically relating to a wheel set and luggage with shock absorption function. Background Technology

[0002] If the luggage wheels lack shock absorption or have poor shock absorption, items inside the luggage will scatter when the road is bumpy, and the wheels are prone to damage. Incorporating shock-absorbing rubber into the wheels can provide some shock absorption, but the rubber's deformation range is limited, making it difficult to eliminate impacts under complex road conditions.

[0003] The wheels are hinged to the suitcase, and springs connect the wheels and the suitcase, allowing the springs to bear the main force and support the suitcase. This provides better shock absorption than shock-absorbing rubber. However, since the ends of the springs are fixedly connected to the wheels and the suitcase, the springs are prone to falling off and the shock-absorbing wheels are prone to damage when used on bumpy roads for a long time. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, such as the springs easily falling off and the shock-absorbing wheels easily being damaged when the wheelsets are used on bumpy roads for a long time, and to provide a wheelset and luggage with shock absorption function.

[0005] To achieve the above objectives, the first aspect of this utility model provides a wheelset with shock absorption function, comprising:

[0006] A support frame, wherein the support frame has an internal space for movement;

[0007] A slider is disposed within the active space and is capable of reciprocating within the active space in a preset direction.

[0008] An elastic element is housed in the movable space, and the elastic element abuts against the bracket and the slider in a preset direction;

[0009] A connecting shaft passes through the bracket and the slider. The connecting shaft can reciprocate in a preset direction within the bracket. Two wheels are connected to the two ends of the connecting shaft.

[0010] Furthermore, the bracket is provided with a first mounting hole, which penetrates the movable space;

[0011] The slider is provided with a second mounting hole, which communicates with the first mounting hole. The first mounting hole is a strip-shaped hole, which is vertically arranged, and the length of the strip-shaped hole is greater than the diameter of the second mounting hole.

[0012] Furthermore, a mounting post is provided at the top of the slider, and part of the elastic element is sleeved on the mounting post.

[0013] Furthermore, it also includes:

[0014] A connecting pin is disposed on the bracket.

[0015] Furthermore, the bracket is also provided with a protruding post, which is located at the side end of the movable space, and the protruding post is provided with an installation groove for installing the connecting nail.

[0016] Furthermore, the elastic element is a spring, with one end of the spring abutting against the inner top of the movable space and the other end abutting against the top of the slider.

[0017] The second aspect of this utility model provides a suitcase, comprising:

[0018] A mounting bracket for connecting to the body of a suitcase and the shock-absorbing wheel set as described in any of the above embodiments, the mounting bracket being mounted on the bracket.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this embodiment of the invention, unless otherwise explicitly specified and limited, terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part of a structure. They can be mechanical or electrical connections. They can be direct connections or indirect connections through an intermediate medium, and can represent the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention based on the specific circumstances.

[0034] This utility model embodiment provides a suitcase, which includes a suitcase body, a mounting base, and a set of shock-absorbing wheels. The mounting base is fixed to the bottom of the suitcase body and is used to connect the wheels and the suitcase body. Four mounting bases are provided at the bottom of the suitcase body, and four sets of shock-absorbing wheels are provided accordingly. The four sets of wheels are located at the four corners of the bottom of the suitcase body, which can ensure the smooth movement of the suitcase. Of course, in some embodiments, wheels can be added in the middle of the bottom of the suitcase body, which is not limited here.

[0035] Combination Figure 1 to Figure 4 The shock-absorbing wheel set provided in this embodiment includes a bracket 10, a slider 20, an elastic element 30, a connecting shaft 40, and a rotating wheel 50.

[0036] An active space 11 is provided inside the support 10. The slider 20 is located within the active space 11 and can reciprocate along a preset direction within the active space 11. It should be understood that the preset direction here refers to the vertical direction, that is, the slider 20 can reciprocate along the vertical direction within the active space 11. The elastic element 30 is housed in the active space 11 and abuts against the support 10 and the slider 20 along the preset direction. It can be understood that the elastic element 30 is also vertically located within the active space 11. The elastic element 30 has a compressed state and a relaxed state. The elastic force of the elastic element 30 is used to dampen the box, specifically to dampen the support 10, thus preventing the support 10 from being damaged by excessive force. The connecting shaft 40 passes through the support 10 and the slider 20. At the two ends of the connecting shaft 40 outside the support 10, there are rotating wheels 50 respectively. Since the connecting shaft 40 passes through the slider 20, when the slider 20 is in the active space 11... During the reciprocating linear motion, the connecting shaft 40, driven by the slider 20, can also reciprocate within the bracket 10 in a preset direction. The shock-absorbing wheel set in this application only requires the bracket 10, slider 20, elastic element 30, connecting shaft 40, and rotating wheel 50. It is simple to assemble, easy to install, has few parts, low cost, and high strength.

[0037] like Figure 5As shown, specifically, the bracket 105 is provided with a first mounting hole 12, which penetrates the movable space 11. The slider 20 is provided with a second mounting hole 21, which communicates with the first mounting hole 12. During installation, the connecting shaft 40 passes through the first mounting hole 12 and the second mounting hole 21 in sequence. The second mounting hole 21 fits tightly with the connecting shaft 40, thus preventing the connecting shaft 40 from shifting vertically relative to the slider 20. The first mounting hole 12 is a strip-shaped hole, vertically positioned, and its length is greater than the diameter of the second mounting hole 21. Therefore, the length of the strip-shaped hole defines the range of motion of the connecting shaft 40. This provides the connecting shaft 40 with a certain buffer range during use, effectively reducing shock.

[0038] like Figure 6 As shown, to ensure stable installation of the elastic element 30, a mounting post 22 is provided at the top of the slider 20. The length of the mounting post 22 is less than the length of the elastic element 30, and part of the elastic element 30 is fitted onto the mounting post 22. When the slider 20 moves within the movable space 11, the elastic element 30 is compressed, and the mounting post 22 can abut against the top of the movable space 11. This prevents the elastic element 30 from failing due to compression. The elastic element 30 and the mounting post 22 work together to achieve shock absorption and provide good support. The elastic element 30 can also reduce the force borne by the mounting post 22, thereby increasing the service life of the slider 20.

[0039] like Figure 1 and Figure 2 As shown, the wheelset also includes a connecting pin 60, which connects the bracket 10 and the mounting base. One end of the connecting pin 60 is located inside the bracket 10, and the other end is located inside the mounting base. Specifically, the bracket 10 also has a protruding post 13 located at the side end of the movable space 11. The protruding post 13 has a mounting groove for installing the connecting pin 60. During installation, the connecting pin 60 is partially in the mounting groove, and the other end is inserted into the mounting base.

[0040] In this application, the elastic element 30 is a spring, which is generally made of spring steel and has good elastic properties, high structural strength, and long service life. The spring is fitted onto the mounting post 22, with its two ends abutting against the slider 20 and the inner top of the movable space 11, respectively. After installation, the outer wall of the spring abuts against the inner wall of the movable space 11, thus preventing the spring from shifting left and right during compression and affecting its service life.

[0041] The wheelset is installed on the mounting base and then on the bottom of the luggage compartment. When the luggage compartment is on uneven road conditions or when it is taken down from a high place (such as inside a car) and placed on the road, the wheel 50 contacts the road surface, the spring is compressed, and the luggage compartment drives the bracket 10 to move downward relative to the wheel 50. The spring's cushioning effect can dampen the movement of the luggage compartment. Since the spring is installed inside the bracket 10, it can prevent the spring from falling off. At the same time, when the spring fails after long-term use, you only need to remove the axle, take out the slider 20 and the spring from inside the bracket 10, and then replace the spring to restore the wheelset's good shock absorption effect.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
