Description

Technical Field

[0001] This application relates to the field of slide rail accessories technology, and in particular to a buffer, buffer device and slide rail system. Background Technology

[0002] Drawer slides are hardware connecting parts fixed to furniture that allow drawers or cabinet panels to move in and out. They are generally used for drawer connections in wooden or steel furniture such as cabinets, furniture, filing cabinets, and bathroom vanities. In traditional drawer slides, when the user closes the drawer forcefully, the slide components move quickly along with the drawer. During this rapid movement, the internal structure of the slide inevitably experiences a certain amount of impact. After prolonged use, this can easily lead to breakage and damage to the internal components of the slide, thus adversely affecting the quality and lifespan of the slide. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this application provides a buffer, a buffer device, and a slide rail system to solve the problems existing in related technologies. The technical solution is as follows:

[0004] In a first aspect, embodiments of this application provide a buffer component, including a buffer component body, with sliding portions for abutting against a slide rail body on both sides of the buffer component body, a guide groove for connecting a damping mechanism being provided at the lower end of the buffer component body, a limiting hole being provided on the buffer component body, and a buffer portion being provided at one end of the buffer component body, the buffer portion communicating with the guide groove, the position of the buffer portion corresponding to the limiting hole.

[0005] In one embodiment, the buffer portion is an unloading groove, which is connected to the guide groove.

[0006] In one embodiment, the limiting hole is an arc-shaped hole, with its two ends located at a first position and a second position, respectively, and one side of the unloading groove corresponding to the first position.

[0007] In one embodiment, a buffer stop is provided at one end of the sliding part, and the buffer stop is located on the same side as the buffer part.

[0008] In one embodiment, a plurality of protrusions are provided on both sides of the lower end of the guide groove to limit the damping mechanism.

[0009] Secondly, embodiments of this application provide a buffer device, including a damping mechanism and a buffer element, wherein the buffer element body is connected to the damping mechanism.

[0010] In one embodiment, the damping mechanism includes: a fixed frame, a slide corresponding to the guide groove is provided on one side of the fixed frame, and a damper, a movable member corresponding to the limiting hole, and at least one spring corresponding to the sliding part are provided on the fixed frame.

[0011] In one embodiment, a receiving cavity is provided on the buffer body to accommodate the movable end of the damper.

[0012] Thirdly, embodiments of this application provide a slide rail system, a slide rail body, and a buffer device, wherein the damping mechanism is disposed at one end of the slide rail body.

[0013] In one embodiment, sliding grooves corresponding to the sliding portion are provided on both sides of the slide rail body.

[0014] The advantages or beneficial effects of the above technical solutions include at least the following:

[0015] The buffer component of this application is used in the drawer slide system of furniture. A buffer part is provided on one side of the buffer component body to relieve impact force. When the user pulls out or closes the drawer forcefully, the rapid movement of the slide system causes a strong impact force between the buffer component and the damping mechanism. The buffer part can disperse the stress, avoid or reduce the risk of the buffer component body 1 breaking due to high stress concentration when it tends to bend. This reduces the damage caused by the impact force to the buffer component body 1, thereby extending the service life of the slide system.

In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of this application will become readily apparent from the accompanying drawings and the following detailed description.

[0030] In the following description, only certain exemplary embodiments are briefly described to make the objectives, features, and advantages of this invention more apparent. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0031] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, this embodiment provides a buffer component, including a buffer component body 1. Sliding portions 101 for abutting against a slide rail body 3 are provided on both sides of the buffer component body 1. A guide groove 102 for connecting a damping mechanism 2 is provided at the lower end of the buffer component body 1. A limiting hole 103 is provided on the buffer component body 1. A buffer portion 104 is provided at one end of the buffer component body 1. The buffer portion 104 communicates with the guide groove 102. The position of the buffer portion 104 corresponds to that of the limiting hole 103.

[0034] In this embodiment, the buffer body 1 has a front end, a rear end, and left and right sides. Two sliding parts 101 are symmetrically arranged on the left and right sides of the buffer body 1 and can abut against the slide rail body 3. The sliding parts 101 on both sides are used to assist the buffer body 1 in linear reciprocating movement on the slide rail body 3. The guide groove 102 opened at the lower end of the buffer body 1 is used to slide and connect with the damping mechanism 2. The buffer body 1 can move linearly and reciprocally on the damping mechanism 2 through the guide groove 102. The limiting hole 103 is provided through the buffer body 1 and communicates with the guide groove 102. The unlocking shaft 204a of the movable part 204 of the damping mechanism 2 passes through the limiting hole 103. The buffer part 104 is arranged at the front end of the buffer body 1. At least a part of the buffer part 104 and at least a part of the limiting hole 103 are on the same straight line. When the limiting hole 103 is subjected to force, the force can be transmitted to the buffer part 104 in a straight line.

[0035] In practical applications, when a user forcefully closes a drawer, the slide rail system moves rapidly. The middle rail impacts the buffer body 1 before the inner rail. At this time, because the unlocking mechanism on the inner rail has not yet contacted the unlocking shaft 204a of the moving part 204 of the damping mechanism 2, a strong impact force is generated between the buffer body 1 and the damper mechanism 2 under the action of the locking shaft 204b of the moving part 204 of the damping mechanism 2. Since the contact point between the middle rail and the buffer body 1 is located at the sliding parts 101 on both sides, and the force points between the buffer body 1 and the damper mechanism 2 are at the two sliding parts... Between 101, the buffer body 1 tends to bend. The front end of the buffer body 1, corresponding to the impact force point, is prone to breakage due to stress concentration. However, this application adds a buffer part 104, and at least a part of the buffer part 104 is on the same straight line as at least a part of the limiting hole 103. The buffer part 104 can generate stress dispersion, avoiding or reducing the risk of the buffer body 1 breaking due to high stress concentration when the buffer body 1 tends to bend, and reducing the damage caused to the buffer body 1 by the impact force.

[0036] Furthermore, the buffer section 104 is an unloading groove, which is connected to the guide groove 102.

[0037] In this embodiment, the structure of the buffer part 104 is designed as a rectangular groove structure. The unloading groove is formed at the front end of the buffer body 1, so that the wall thickness of the unloading groove is different from the wall thickness of other parts of the buffer body 1. The different wall thicknesses make the front end of the buffer body 1 form a stepped structure. This structure is beneficial for the buffer body 1 to disperse and release the impact force, thereby reducing the damage caused by the impact force to the buffer body 1.

[0038] Furthermore, the limiting hole 103 is an arc-shaped hole, with its two ends located at the first position 105 and the second position 106, respectively, and the unloading groove corresponds to the first position 105.

[0039] In this embodiment, the limiting hole 103 is designed as an arc-shaped hole (the arc-shaped hole structure is shaped like a kidney bean). The unlocking shaft 204a of the movable part 204 of the damping mechanism 2 passes through the limiting hole 103, so that the unlocking shaft 204a of the movable part 204 of the damping mechanism 2 can reciprocate in an arc-shaped trajectory within the range limited by the limiting hole 103.

[0040] The two ends of the arc-shaped hole are located at the first position 105 and the second position 106, respectively. See Figure 3 One side of the unloading groove is on the same straight line as the first position 105, thereby enhancing the deformability of the buffer body 1. When the first position 105 on the arc hole is subjected to force, the force can be transmitted in a straight line to the unloading groove position, reducing the damage caused by the impact force to the buffer body 1.

[0041] Furthermore, a buffer stop 107 is provided at one end of the sliding part 101, and the buffer stop 107 is located on the same side as the buffer part 104.

[0042] In this embodiment, there are two buffer ears 107. The two buffer ears 107 are symmetrically arranged in a mirror image at one end of the sliding part 101 on both sides, and the two buffer ears 107 and the buffer part 104 are located on the same side. That is, the buffer ears 107 and the unloading groove are both located at the front end of the buffer body 1. The buffer ears 107 can abut against the middle rail of the slide rail system. The buffer ears 107 can also offset part of the impact force generated when the middle rail of the slide rail system moves quickly, thereby providing a further buffering effect on the buffer body 1.

[0043] Furthermore, a plurality of protrusions 108 are provided on both sides of the lower end of the guide groove 102 to limit the damping mechanism 2.

[0044] In this embodiment, a plurality of protrusions 108 are respectively disposed on both sides of the lower end of the guide groove 102. The protrusions 108 abut against the damping mechanism 2, so that the damping mechanism 2 is located between the guide groove 102 and the protrusions 108. The buffer body 1 can slide back and forth on the damping mechanism 2, and is not easy to fall off under the limiting effect of the protrusions 108.

[0045] Example 2

[0046] like Figures 1 to 7 As shown, this embodiment provides a buffer device, including a damping mechanism 2 and a buffer component, wherein the buffer component body 1 is connected to the damping mechanism 2.

[0047] Furthermore, the damping mechanism 2 includes: a fixed frame 201, a slide rail 202 corresponding to the guide groove 102 is provided on one side of the fixed frame 201, and a damper 203, a movable part 204 corresponding to the limiting hole 103, and at least one spring 205 corresponding to the sliding part 101 are provided on the fixed frame 201.

[0048] In this embodiment, the slide rail 202 is located at one end of the fixing frame 201 and protrudes outward, see [reference]. Figure 5 and Figure 6 The slide 202 corresponds to and is adapted to the guide groove 102 on the buffer body 1. The buffer body 1 is engaged on the slide 202 under the cooperation of the guide groove 102 and multiple protrusions 108, so that the buffer body 1 can move linearly back and forth on the slide 202 and is not easy to fall off. The damper 203 is installed on the fixed frame 201. The movable end of the damper 203 is connected to the buffer body 1, which can generate damping force on the buffer body 1 to prevent the buffer body 1 from moving too fast.

[0049] In this embodiment, springs 205 are provided on both sides of the fixing frame 201. Both springs 205 are connected to the sliding part 101 of the buffer body 1. The springs 205 are compression springs. When the buffer body 1 moves away from the fixing frame 201, the springs 205 are stretched. The buffer body 1 can be elastically reset after moving on the slide 202 through the springs 205.

[0050] In this embodiment, one side of the movable member 204 is rotatably mounted on the buffer body 1, and the other side of the movable member 204 has an unlocking shaft 204a and a locking shaft 204b, wherein the unlocking shaft 204a and the locking shaft 204b are located on the same vertical line, see [reference]. Figure 7 The locking shaft 204b of the movable component 204 is movably mounted on the slide rail 202, and the unlocking shaft 204a of the movable component 204 passes through the limiting hole 103. Through the arc-shaped limiting structure of the limiting hole 103, the unlocking shaft 204a of the movable component 204 can rotate within a certain angle range. The slide rail 202 has a locking position. When the locking shaft 204b is in the locking position, the unlocking shaft 204a is in the first position 105. At this time, the buffer body 1 is stopped in the open position (i.e.,...). Figure 5 (as shown in the figure), and the inner rail is provided with an unlocking component. During the closing process of the inner rail, the unlocking structure on the inner rail can drive the unlocking shaft 204a from the first position 105 to the second position 106. At this time, the spring 205 will drive the buffer body 1 to slide along the slide 202 to the closed position.

[0051] Furthermore, a receiving cavity 206 is provided on the buffer body 1 to accommodate the movable end of the damper 203, and the receiving cavity 206 corresponds to the position of the limiting hole 103.

[0052] In this embodiment, the movable end of the damper 203 is disposed within the receiving cavity 206. When the buffer body 1 moves along the slide 202 toward the fixed frame 201, the damper 203 generates a damping force on the buffer body 1, thereby preventing the buffer body 1 from moving too fast and causing an impact. See [link to previous section] Figure 3 , Figure 5 and Figure 6 The receiving cavity 206 is located at the rear end of the buffer body 1, and the receiving cavity 206 coincides with the horizontal section of the slide 202, so as to make the sliding of the buffer body 1 more stable.

[0053] Example 3

[0054] like Figures 1 to 8 As shown, this embodiment provides a slide rail system, including a slide rail body 3 and a buffer device, wherein the damping mechanism 2 is disposed at one end of the slide rail body 3.

[0055] In this embodiment, the fixing frame 201 of the damping mechanism 2 is installed at the end of the slide rail body 3, and the buffer body 1 is movably disposed on the slide rail body 3. The buffer body 1, the damping mechanism 2 and the slide rail body 3 together constitute the slide rail system. The structure and working principle of the buffer body 1 and the damping mechanism 2 are the same as those in Embodiment 1 and Embodiment 2 above, and will not be repeated here.

[0056] Furthermore, sliding grooves 301 corresponding to the sliding part 101 are provided on both sides of the slide rail body 3.

[0057] In this embodiment, two sliding grooves 301 are symmetrically arranged on the inner walls of both sides of the slide rail body 3, and the sliding portions 101 on both sides of the buffer body 1 are adapted to the positions of the sliding grooves 301. See [reference needed] Figure 7 This allows the buffer body 1 to slide back and forth linearly along the sliding groove 301 on the slide rail body 3.

[0058] In addition, a semi-circular recessed structure is provided on the inner side of the sliding groove 301, and a semi-circular protruding structure is provided on the outer side of the sliding part 101. The semi-circular recessed structure and the semi-circular protruding structure are interlocked with each other, so that the guiding effect of the slide rail body 3 on the sliding part 101 is more precise, and thus the movement of the buffer body 1 on the slide rail body 3 is smoother.

The functions of each module in each device in the embodiment can be found in the corresponding description in the above method. By dispersing the impact force generated when the slide rail system moves rapidly through the buffer structure, the damage caused by the impact force to the slide rail system can be reduced, thereby extending the service life of the slide rail system.
