Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of damping and buffering, in particular to a damping mechanism. Background Art
[0002] As a type of storage cabinet, right-angle rotating cabinets cleverly utilize the space at the corners of a room for storage, effectively increasing storage space and being particularly practical for smaller rooms. Current rotating cabinets typically consist of a fixed cabinet body, a rotating cabinet body, and a rotating and translating mechanism located between the fixed and rotating cabinet bodies. When the rotating cabinet body rotates relative to the fixed cabinet body, it is necessary to prevent excessive impact forces between the components in the rotating and translating mechanism to avoid damage to the components and noise. Dampers are commonly used to address this issue, but existing dampers generally suffer from poor cushioning and are easily damaged. Utility Model Content

[0027] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings and are constructed and operated in specific directions. They are only for the convenience of describing the present technical solution and do not indicate that the devices or components referred to must have specific directions. Therefore, they should not be understood as limiting the present invention.
[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] Please refer to Figures 1 to 4 An embodiment of the present application provides a damping mechanism 30 , which is used to apply a load to the movement of the moving plate 20 , and the moving plate 20 can move relative to the fixed plate 10 .
[0030] Specifically, the damping mechanism 30 includes a rack 31, a damper 32, a damper gear 33, and a reset elastic member 34. The rack 31 is provided on one of the moving plate 20 and the fixed plate 10 and extends along the direction of movement of the moving plate 20. The rack 31 has an abutment portion, on which rack gears 31a are spaced apart along the direction of movement of the moving plate 20. The damper 32 is provided on the other of the moving plate 20 and the fixed plate 10. The damper 32 has a rotating shaft 32a extending toward the rack 31, and the rotating shaft 32a is located outside the abutment portion. The damper gear 33 is mounted on the rotating shaft 32a and meshes with the rack gear 31a. One end of the reset elastic member 34 is connected to the moving plate 20, and the other end is connected to the fixed plate 10. The reset elastic member 34 is adapted to provide a rebound force to pull the moving plate 20 back to its initial position.
[0031] Exemplarily, the rack 31 is disposed on either the moving plate 20 or the fixed plate 10, meaning that the rack 31 can be disposed on either the moving plate 20 or the fixed plate 10, depending on the specific circumstances. However, it should be noted that the damper 32 and the rack 31 are disposed opposite each other. That is, if the rack 31 is disposed on the moving plate 20, the damper 32 is disposed on the fixed plate 10; if the rack 31 is disposed on the fixed plate 10, the damper 32 is disposed on the moving plate 20. In other words, the rack 31 and the damper 32 cannot be disposed on the same plate. This ensures that during movement of the moving plate 20, the damper gear 33 mounted on the rotating shaft 32a can engage with the rack 31, allowing the damper 32 to generate a damping effect, thereby mitigating the impact force generated by the moving plate 20's own weight during movement and preventing damage to the components due to collision.
[0032] It should be noted that when the moving plate 20 moves relative to the fixed plate 10, the damper 32 slows the rotation of the rotating shaft 32a, thereby slowing the rotation of the damper gear 33, thereby providing a damping and buffering effect. Specifically, the rotation of the rotating shaft 32a can be slowed by disposing silicone oil in the inner cavity of the damper 32, thereby utilizing the higher viscosity of the silicone oil to slow the rotation of the rotating shaft 32a.
[0033] Based on the damping mechanism 30 of the above-mentioned technical features, the damper gear 33 is mounted on the rotating shaft 32a of the damper 32 and meshes with the rack gear 31a of the rack 31. When the moving plate 20 moves relative to the fixed plate 10, the damper 32 can slow the rotation speed of the rotating shaft 32a, causing the sliding of the rack 31 to gradually slow down, thereby providing a buffer for the moving plate 20, thereby reducing the impact force generated by the moving plate 20's own gravity during movement and preventing damage to the accessories due to collisions. In addition, the reset elastic member 34 can provide a rebound force to pull the moving plate 20 back to its initial position, eliminating the need for manual push-back.
[0034] For example, the return spring 34 is adapted to provide a rebound force to pull the moving plate 20 back to its initial position. Specifically, after the moving plate 20 reaches its maximum movement position, the return spring 34 is in a stretched state. At this point, if the force exerted on the moving plate 20 is released, the return spring 34 switches from the stretched state to a relaxed state. During this process, the return spring 34 pulls the moving plate 20 back to its initial position, eliminating the need for manual retraction. Furthermore, the return spring 34 may be a tension spring or an elastic member capable of providing the rebound force required to return the moving plate 20 to its initial position, without limitation.
[0035] In actual application, the rack 31 is arranged on the fixed plate 10, the damper 32 is arranged on the moving plate 20, and the rotating shaft 32a of the damper 32 extends toward the rack 31 and is located on the outside of the abutment portion, so that after the damper gear 33 is mounted on the rotating shaft 32a, the damper gear 33 can engage with the rack gear 31a of the rack 31.
[0036] Specifically, the fixing bar 35 is fixed to the surface of the fixed plate 10 facing the moving plate 20 and extends along the movement direction of the moving plate 20. A first mounting hole 35a is formed on the fixing bar 35 and passes through the fixing bar 35. A second mounting hole is formed on the rack 31 and passes through the rack 31 itself at a position opposite the first mounting hole 35a. A fastener (such as a bolt) is sequentially passed through the aligned first mounting hole 35a and the second mounting hole and driven into the fixing plate 10, thereby mounting the rack 31 on the fixing bar 35. In other words, when the rack gear 31a of the rack 31 is damaged and needs to be replaced, it is only necessary to loosen the fastener and remove it from the first mounting hole 35a and the second mounting hole, and then remove the rack 31 from the fixing bar 35. The structure is simple and the installation is convenient.
[0037] In one embodiment, a connecting ear 80 extends outward from the outer surface of the damper 32, and the connecting ear 80 is connected to one end of the moving plate 20. It should be noted that the connection between the connecting ear 80 and the outer surface of the damper 32 can be integrally formed, so that the connecting ear 80 and the damper 32 form an integral unit. This eliminates the need for a connection between the connecting ear 80 and the damper 32, thereby ensuring the structural strength of the damper 32.
[0038] Specifically, a first fixing hole 80a is defined in the connecting ear 80, and a second fixing hole is defined in the position on the moving plate 20 for connecting to the damper 32. In other words, when mounting the damper 32 on the moving plate 20, the first fixing hole 80a of the connecting ear 80 is first aligned with the second fixing hole on the moving plate 20. A fastener is then inserted sequentially through the first fixing hole 80a and the second fixing hole to removably mount the damper 32 on the moving plate 20, facilitating subsequent replacement or maintenance.
[0039] In one embodiment, it also includes a guide wheel 37 and a mounting plate 36. The mounting plate 36 is connected to one end of the fixed plate 10 facing the surface of the moving plate 20, and the mounting plate 36 extends toward the moving plate 20. The guide wheel 37 is installed on the surface of the mounting plate 36, and the reset elastic member 34 is wrapped around the guide wheel 37.
[0040] For example, the guide wheel 37 is connected to the fixed plate 10 using the mounting plate 36, and the reset elastic is wound around the guide wheel 37 so as to guide the reset elastic member 34, and then the reset elastic member 34 is folded into two parts to ensure that the moving plate 20 can be pulled back to its initial position by the rebound force of the reset elastic member 34 after the moving plate 20 moves to the maximum translation distance.
[0041] In one embodiment, the end of the moving plate 20 away from the damper 32 is bent toward the fixed plate 10 to form a first fixing block 60. The first fixing block 60 has a first slot 60a defined therein. The end of the return elastic member 34 connected to the moving plate 20 is engaged in the first slot 60a. The end of the fixed plate 10 away from the guide wheel 37 is bent toward the moving plate 20 to form a second fixing block 70. The second fixing block 70 has a second slot 70a defined therein. The end of the return elastic member 34 connected to the fixed plate 10 is engaged in the second slot 70a.
[0042] For example, a first fixed block 60 and a second fixed block 70 are bent on the moving plate 20 and the fixed plate 10, respectively, and a first bayonet 60a is opened on the first fixed block 60, and a second bayonet 70a is opened on the second fixed block 70. Then, the two ends of the reset elastic member 34 are respectively inserted into the first bayonet 60a and the second bayonet 70a, so that the reset elastic member 34 is connected to the moving plate 20 and the fixed plate 10 in a detachable manner. The structure is simple and easy to disassemble and assemble, which is conducive to the subsequent rapid replacement of the reset elastic member 34.
[0043] In one embodiment, the device further includes a slide rail 40 and a slider 50. The slide rail 40 is provided on the surface of the fixed plate 10 facing the moving plate 20 and is arranged along the direction of movement of the moving plate 20. The slider 50 is slidably connected to the slide rail 40 and is connected to the moving plate 20. In this way, when the moving plate 20 is pushed to move, the slider 50 connected to the moving plate 20 can be driven to move on the slide rail 40, ensuring that the moving plate 20 reciprocates only in a predetermined direction and does not deviate.
[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
