Abstract

This invention provides a hinge structure, a side case, and a motorcycle. The hinge structure includes a first hinge, a second hinge, a rotating shaft, a damping element, and an elastic element. The first hinge has a first mounting hole. The second hinge has a second mounting hole. The rotating shaft passes through the first and second mounting holes. The damping element is sleeved on the rotating shaft and abuts against the inner walls of both the first and second mounting holes. The elastic element is sleeved on the rotating shaft and is fixedly connected to both the first and second hinges. In this application, the first and second hinges cooperate to compress the elastic element, causing the elastic element to deform and buffer the second hinge. Simultaneously, the damping element rubs against the inner walls of both the first and second mounting holes to generate resistance, slowing down the rotation speed of the second hinge, reducing the probability of violent collisions between the side case cover and the case body, increasing the service life of the side case, improving the user experience, and reducing safety hazards.

Description

Technical Field

[0001] This invention relates to the field of hinge technology, and in particular to a hinge structure, a side case, and a motorcycle. Background Technology

[0002] Existing motorcycle side cases typically use a hinge structure for rotational connection, with no structure to fix the opening and closing of the case lid. The rapid closing speed of the case lid causes violent collisions between the upper and lower lids, resulting in abnormal noises, reduced product lifespan, increased market failure rate, and in special cases, safety hazards to the operator (hands may be pinched when the lid is opened and closed), leading to a poor user experience. Summary of the Invention

[0003] Therefore, it is necessary to provide a hinge structure, side case, and motorcycle to address the problems of existing motorcycle side cases having short service life, high market failure rate, safety hazards to operators in special circumstances (hand pinching when opening and closing the cover), and poor user experience.

[0004] The technical solution is as follows:

[0005] Firstly, a hinge structure is provided, comprising:

[0006] A first hinge, wherein the first hinge is provided with a first mounting hole;

[0007] The second hinge has a second mounting hole that communicates with the first mounting hole.

[0008] A rotating shaft, which passes through the first mounting hole and the second mounting hole;

[0009] A damping element, which is sleeved on the rotating shaft and abuts against the inner wall of both the first mounting hole and the inner wall of the second mounting hole; and

[0010] An elastic element is sleeved on the rotating shaft and is fixedly connected to both the first hinge and the second hinge.

[0011] In the hinge structure described above, during use, the first hinge is fixedly connected to one side of the box body, and the second hinge is fixedly connected to one side of the box lid to assemble a side box. When the side box needs to be closed, an external force is applied to the box lid, causing the box lid to rotate the second hinge towards the box body. During the rotation of the second hinge towards the box body, the first and second hinges cooperate to compress the elastic element, thereby causing the elastic element to compress and deform to buffer the second hinge. At the same time, the damping element rubs against the inner walls of the first and second mounting holes to generate resistance, thereby slowing down the rotation speed of the second hinge, reducing the probability of a violent collision between the box lid and the box body, increasing the service life of the side box, improving the user experience, and reducing safety hazards. When the side box needs to be opened, the locking fit between the box cover and the box body is released, and the elastic element releases its elastic potential energy to drive the second hinge to reset. During the reset process of the second hinge, the damping element rubs against the inner wall of the first mounting hole and the inner wall of the second mounting hole again to generate resistance, causing the second hinge to slowly rotate away from the box body and automatically reach the end point under the action of the elastic element, thereby allowing the box cover to be fully opened.

[0012] The technical solution will be further explained below:

[0013] In one embodiment, the first hinge is provided with two first connecting portions spaced apart, and each of the two first connecting portions is provided with a first mounting hole. The second hinge is provided with two second connecting portions spaced apart, and each of the two second connecting portions is located between the two first connecting portions. Each of the two second connecting portions is provided with a second mounting hole. The rotating shaft passes through the two first mounting holes and the two second mounting holes respectively.

[0014] In one embodiment, the elastic element is configured as a spring, which is located between the two second connecting portions.

[0015] In one embodiment, the first hinge is further provided with a protective part, which is located between the two second connecting parts. The protective part, the two second connecting parts and the second hinge form a protective space, and the spring is located within the protective space.

[0016] In one embodiment, the protective part slides in conjunction with the second hinge in the circumferential direction along the rotation axis.

[0017] In one embodiment, the first connecting portion, the first hinge, and the protective portion cooperate to form a limiting groove, and the second connecting portion extends into the limiting groove and is limited and engaged with the inner sidewall of the limiting groove.

[0018] In one embodiment, the damping element is configured as a damping column, and there are two damping columns. The two damping columns are correspondingly provided with the two first mounting holes and the two second mounting holes. The ends of the two damping columns that are close to each other extend into the spring, and the ends of the two damping columns that are close to each other are in a limiting fit.

[0019] In one embodiment, a limiting part is provided at one end of the rotating shaft, and the hinge structure further includes a first washer, a second washer, and a retaining spring. The first washer and the second washer are both sleeved on the rotating shaft. One side of the first washer is limited to the damping member and the first connecting part, and the other side of the first washer is limited to the limiting part. One side of the second washer is limited to the damping member and another first connecting part. The retaining spring is fixed to the other end of the rotating shaft and is limited to the other side of the second washer.

[0020] Secondly, a side box is provided, including a box body, a box cover, and the aforementioned hinge structure, wherein the hinge structure is used to rotatably connect one side of the box body to one side of the box cover.

[0021] In the side case described above, during use, the first hinge is fixedly connected to one side of the case body, and the second hinge is fixedly connected to one side of the case lid to assemble the side case. When the side case needs to be closed, an external force is applied to the case lid, causing it to rotate the second hinge towards the case body. During this rotation, the first and second hinges work together to compress the elastic element, causing it to deform and buffer the second hinge. Simultaneously, the damping element rubs against the inner walls of the first and second mounting holes to generate resistance, thereby slowing down the rotation speed of the second hinge, reducing the probability of a violent collision between the case lid and the case body, increasing the lifespan of the side case, improving the user experience, and reducing safety hazards. When the side box needs to be opened, the locking fit between the box cover and the box body is released, and the elastic element releases its elastic potential energy to drive the second hinge to reset. During the reset process of the second hinge, the damping element rubs against the inner wall of the first mounting hole and the inner wall of the second mounting hole again to generate resistance, causing the second hinge to slowly rotate away from the box body and automatically reach the end point under the action of the elastic element, thereby allowing the box cover to be fully opened.

[0022] Thirdly, a motorcycle is provided, including a vehicle body and the side cases, the side cases being mounted on the vehicle body.

[0023] In the motorcycle described above, during use, the first hinge is fixedly connected to one side of the box body, and the second hinge is fixedly connected to one side of the box cover to form a side box. The side box is then mounted onto the motorcycle body. When the side box needs to be closed, an external force is applied to the cover, causing it to rotate the second hinge towards the box body. During this rotation, the first and second hinges work together to compress an elastic element, causing it to deform and buffer the second hinge. Simultaneously, the damping element rubs against the inner walls of the first and second mounting holes to generate resistance, thereby slowing the rotation speed of the second hinge, reducing the probability of a violent collision between the box cover and the box body, increasing the side box's lifespan, improving the motorcycle's user experience, and reducing safety hazards. When the side case needs to be opened, the locking mechanism between the case cover and the case body is released. The elastic element releases its elastic potential energy to drive the second hinge to reset. During the reset process of the second hinge, the damping element rubs against the inner walls of the first mounting hole and the second mounting hole again to generate resistance, causing the second hinge to rotate slowly away from the case body. Under the action of the elastic element, it automatically reaches the end point, thereby allowing the case cover to be fully opened and improving the automation level of the motorcycle.

[0030] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0031] like Figure 1 As shown, in one embodiment, a side box 1 is provided, including a box body 20, a box lid 30, and a hinge structure 10. The hinge structure 10 is used to rotatably connect one side of the box body 20 to one side of the box lid 30. In this way, the box lid 30 can rotate around one side of the box body 20 through the hinge structure 10, so that the box lid 30 can open or close the box body 20, improving the practicality of the side box 1.

[0032] The hinge structure 10 can be applied to the side box 1, doors, windows, cabinets, or other products. This application uses the application of the hinge structure 10 to the side box 1 as an example and should not be construed as a limitation of this application.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, a hinge structure 10 is provided, including a first hinge 100, a second hinge 200, a rotation shaft 300, a damping element 400, and an elastic element 500. The first hinge 100 has a first mounting hole 111. The second hinge 200 has a second mounting hole 211 corresponding to and communicating with the first mounting hole 111. The rotation shaft 300 passes through the first mounting hole 111 and the second mounting hole 211. The damping element 400 is sleeved on the rotation shaft 300 and abuts against the inner walls of both the first mounting hole 111 and the second mounting hole 211. The elastic element 500 is sleeved on the rotation shaft 300 and is fixedly connected to both the first hinge 100 and the second hinge 200.

[0034] In the hinge structure 10 described above, during use, the first hinge 100 is fixedly connected to one side of the housing 20, and the second hinge 200 is fixedly connected to one side of the lid 30 to assemble the side box 1. When the side box 1 needs to be closed, an external force is applied to the lid 30, causing the lid 30 to rotate the second hinge 200 toward the housing 20. During the rotation of the second hinge 200 toward the housing 20, the first hinge 100 and the second hinge 200 cooperate to compress the elastic element 500, thereby causing the elastic element 500 to compress and deform to buffer the second hinge 200. At the same time, the damping element 400 rubs against the inner wall of the first mounting hole 111 and the inner wall of the second mounting hole 211 to generate resistance, thereby slowing down the rotation speed of the second hinge 200, reducing the probability of a violent collision between the lid 30 and the housing 20, increasing the service life of the side box 1, improving the user experience, and reducing safety hazards. When the side box 1 needs to be opened, the locking fit between the box cover 30 and the box body 20 is released. The elastic element 500 releases its elastic potential energy to drive the second hinge 200 to reset. During the reset process of the second hinge 200, the damping element 400 rubs against the inner wall of the first mounting hole 111 and the inner wall of the second mounting hole 211 again to generate resistance, causing the second hinge 200 to slowly rotate in a direction away from the box body 20, and automatically reach the end point under the action of the elastic element 500, thereby making the box cover 30 fully open.

[0035] In other embodiments, the first hinge 100 in the side box 1 may also be fixedly connected to one side of the box cover 30, and the second hinge 200 may be fixedly connected to one side of the box body 20. The box cover 30 may also be opened by external force.

[0036] like Figure 2 As shown, the first hinge 100 is further provided with two first connecting portions 110 spaced apart, each of which has a first mounting hole 111. The second hinge 200 is provided with two second connecting portions 210 spaced apart, each located between the two first connecting portions 110, and each of which has a second mounting hole 211. The rotating shaft 300 passes through the two first mounting holes 111 and the two second mounting holes 211 respectively. In this way, the number of contact surfaces between the damping member 400 and the first hinge 100 and the second hinge 200 increases, ensuring that the damping member 400 can slow down the rotation speed of the second hinge 200 and improve the reliability of the hinge structure 10.

[0037] like Figure 2Optionally, the elastic element 500 is configured as a spring, located between the two second connecting portions 210. In this way, the two second connecting portions 210 can cooperate to limit the spring, ensuring that the spring's position on the rotation shaft 300 remains fixed, thus improving the reliability of the hinge structure 10. Specifically, in this embodiment, both ends of the spring are fixedly connected to the first hinge 100 and the second hinge 200, respectively.

[0038] like Figure 2 As shown, in one embodiment, the first hinge 100 is further provided with a protective portion 120, which is located between the two second connecting portions 210. The protective portion 120, the two second connecting portions 210, and the second hinge 200 form a protective space, within which the spring is located. Thus, the protective portion 120 can protect the spring, preventing objects from the external environment from entering the protective space and interfering with the spring, thereby improving the reliability and safety of the hinge structure 10. Furthermore, the protective portion 120 also enhances the aesthetics of the hinge structure 10. Specifically, in this embodiment, the protective portion 120 is configured as an arc-shaped seat, the inner contour shape of which matches the outer contour shape of the spring.

[0039] like Figure 2 As shown, optionally, the protective part 120 and the second hinge 200 are slidably engaged along the circumferential direction of the rotation axis 300. This ensures that there is no interference between the protective part 120 and the second hinge 200, thereby ensuring that the lid 30 can smoothly rotate relative to the box body 20 via the first hinge 100, the rotation axis 300, and the second hinge 200 to open or close the box body 20, improving the reliability of the hinge structure 10.

[0040] like Figure 2 As shown, optionally, the first connecting part 110, the first hinge 100, and the protective part 120 cooperate to form a limiting groove 130, and the second connecting part 210 extends into the limiting groove 130 and is limited and engaged with the inner sidewall of the limiting groove 130. In this way, the limiting groove 130 can play a limiting and positioning role, ensuring that the second hinge 200 can be quickly, accurately, and reliably installed at the corresponding position of the first hinge 100 by the second connecting part 210 and the limiting groove 130, thereby improving the reliability of the hinge structure 10 and the convenience of assembly.

[0041] like Figure 2 As shown, in one embodiment, the damping element 400 is configured as a damping column, and there are two damping columns. Each of the two damping columns corresponds to one of the two first mounting holes 111 and the other to one of the two second mounting holes 211. The ends of the two damping columns that are close to each other extend into the spring, and these ends are engaged in a limiting fit. In this way, the outer wall of the damping column can also engage with the inner wall of the spring, increasing the resistance experienced by the damping column and ensuring that it can slow down the rotation speed of the second hinge 200, thus improving the reliability of the hinge structure 10.

[0042] like Figure 2 As shown, optionally, each of the two damping columns has a guide portion 410 at one end that is close to the other. In this way, the damping column can pass through the first mounting hole 111 and the second mounting hole 211 quickly and accurately under the guidance of the guide portion 410 and extend into the spring, improving the ease of assembly of the hinge structure 10.

[0043] The guide part 410 can be configured as an arc surface, a conical surface, or other guide structures.

[0044] like Figure 2 As shown, in one embodiment, a limiting part 310 is provided at one end of the rotating shaft 300, and the hinge structure 10 further includes a first washer 600, a second washer 700, and a retaining ring 800. The first washer 600 and the second washer 700 are both sleeved on the rotating shaft 300. One side of the first washer 600 is limited to the damping member 400 and the first connecting part 110, and the other side of the first washer 600 is limited to the limiting part 310. One side of the second washer 700 is limited to the damping member 400 and the other first connecting part 110. The retaining ring 800 is fixed to the other end of the rotating shaft 300 and is limited to the other side of the second washer 700. In this way, the rotating shaft 300 can cooperate with the first washer 600, the second washer 700 and the snap ring 800 to connect the first hinge 100 and the second hinge 200 into one unit, ensuring that the damping element 400 and the spring element will not slip off the rotating shaft 300, thereby improving the reliability of the hinge structure 10.

[0045] In this specific embodiment, the rotating shaft 300 can be configured as a pin, with one side of the pin passing through the first washer 600, the two damping posts, and the second washer 700. A spring is fitted onto the connection point of the two damping posts. The two damping posts are correspondingly inserted into the two first connecting portions 110 and the two second connecting portions 210. A groove is provided at the end of the pin away from the contact portion, which is used to engage and fix it with the retaining spring 800.

[0046] In one embodiment, a motorcycle is provided, including a vehicle body and a side box 1 as described in any of the above embodiments, the side box 1 being mounted on the vehicle body.

[0047] In the motorcycle described above, during use, the first hinge 100 is fixedly connected to one side of the housing 20, and the second hinge 200 is fixedly connected to one side of the cover 30 to assemble the side box 1. The side box 1 is then mounted on the motorcycle body. When the side box 1 needs to be closed, an external force is applied to the cover 30, causing it to rotate the second hinge 200 towards the housing 20. During this rotation, the first hinge 100 and the second hinge 200 work together to compress the elastic element 500, causing the elastic element 500 to compress and deform, thus buffering the second hinge 200. Simultaneously, the damping element 400 rubs against the inner walls of the first mounting hole 111 and the second mounting hole 211 to generate resistance, thereby slowing down the rotation speed of the second hinge 200, reducing the probability of a violent collision between the cover 30 and the housing 20, increasing the service life of the side box 1, improving the user experience of the motorcycle, and reducing safety hazards. When the side box 1 needs to be opened, the locking engagement between the box cover 30 and the box body 20 is released. The elastic element 500 releases its elastic potential energy to drive the second hinge 200 to reset. During the reset process of the second hinge 200, the damping element 400 rubs against the inner wall of the first mounting hole 111 and the inner wall of the second mounting hole 211 again to generate resistance, causing the second hinge 200 to slowly rotate in a direction away from the box body 20 and automatically reach the end point under the action of the elastic element 500, thereby making the box cover 30 fully open and improving the automation level of the motorcycle.
