[0036] The present disclosure provides the following description with reference to the accompanying drawings to assist in a comprehensive understanding of the various embodiments of the present disclosure as defined by the claims and their equivalents. The description includes various specific details to assist in understanding, but these details should be considered as exemplary only. Therefore, it will be appreciated by those of ordinary skill in the art that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the present disclosure. In addition, for clarity and conciseness, the description of the disclosed functions and configurations may be omitted.

[0037] The terms and words used in the following description and claims are not limited to the literal meanings, but are merely used by the inventor to enable a clear and consistent understanding of the present disclosure. Therefore, it should be clear to those skilled in the art that the following description of various embodiments of the present disclosure is provided for illustration only, and is not intended to limit the present disclosure as defined by the attached claims and their equivalents.

[0038] The terms "having", "may have", "include" or "may include" used in various embodiments of the present disclosure indicate the existence of the corresponding functions, operations, elements, etc. disclosed, but do not limit the additional one or more functions, operations, elements, etc. In addition, it should be understood that the terms "including" or "having" used in various embodiments of the present disclosure are intended to indicate the existence of the features, numbers, operations, elements, components, or combinations thereof described in the specification, but do not exclude the existence or addition of one or more other features, numbers, operations, elements, components, or combinations thereof.

[0039] It will be understood that when an element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0040] like Figure 1 As shown, the pocket door system involved in the present invention includes a door body 40, a track 400 and a damper, and the damper includes a damper body 100. The damper body 100 is arranged in the track 400 and can slide along the track 400. The door body 40 can be connected to the damper body 100 through a suspension rod, so that the door body 40 and the damper body 100 are linked. The extension direction of the track 400, the length direction of the damper body 100, the door opening direction of the door body 40 and the door closing direction of the door body 40 are all parallel. A stopper is arranged in the track 400. During the process of closing and opening the door, the stopper can cooperate with the damper to play a buffering role to prevent the door body 40 from colliding with the door frame.

[0041] An embodiment of the present invention provides a pocket door damper, such as Figure 2 , Figure 3 , Figure 4 , Fig.11 , Fig.12 and Fig.13 As shown, it includes a damper body 100, an energy storage elastic member 210, a movable assembly 220, a buffer assembly 320 and a sliding block 310. Usually, in order to facilitate the movement of the damper body 100 in the track, the damper body 100 is rotatably connected to the pulley 110. The buffer assembly 320 includes a first clamp 321, a buffer, a blocking block 323 and a limiting elastic member 324. The first clamp 321 is slidably connected to the damper body 100 along the length direction of the damper body 100, and the buffer is connected to the first clamp 321. During the door opening process, the first clamp 321 applies a reaction force to the door body under the action of the buffer, so that the door body slowly closes, which plays a buffering role. Since the first clamp 321 and the buffer are already in the prior art, their specific structures are not repeated. In the preset door closing direction, the blocking block 323 is located in front of the first clamping member 321, and the two ends of the limiting elastic member 324 abut against the blocking block 323 and the first clamping member 321, so that when the user presses the door body, the first clamping member 321 can squeeze the limiting elastic member 324. The sliding block 310 and the first clamping member 321 are linked in the length direction of the damper body 100, so the sliding block 310 can be slidably connected with the first clamping member 321 relative to the damper body along the length direction of the damper body 100. The sliding block 310 is provided with a booster 311.

[0042] The movable assembly 220 is slidably connected to the damper body 100 along the length direction of the damper body 100, and the movable assembly 220 includes a movable base 222 and a movable stopper 221 movably connected to the movable base 222. During the door opening process, the stopper in the track will block the movable stopper 221, so that the movable assembly 220 can slide along the length direction of the damper body 100. During the door closing process, since the movable stopper 221 is movably connected to the movable base 222, the movable stopper 221 can move downward so as not to collide with the stopper in the track and not to block the door body from closing. The damper body 100 is provided with an abutment portion 103, which can be a part of the damper body 100 or can be mounted and fixed on the damper body 100. The abutment portion 103 and the movable base 222 are distributed along the length direction of the damper body 100, and the two ends of the energy storage elastic member 210 abut the movable base 222 and the abutment portion 103 respectively, so that when the movable base 222 slides along the length direction of the damper body 100, the energy storage elastic member 210 can store energy, and when the energy storage elastic member 210 releases energy, the damper body 100 can be pushed along the length direction of the damper body 100. The movable component 220 has a locking state and a release state. When the movable component 220 is in the locking state, the energy storage elastic member 210 stores energy, and when the movable component 220 is in the release state, the energy storage elastic member 210 releases energy to drive the damper body 100 to slide along the length direction of the damper body 100. When the booster 311 touches the movable stopper 221 along the length direction of the damper body 100, the movable component 220 can be switched from the locking state to the release state.

[0043] During the door opening process, the door body drives the damper body 100 to move in the door opening direction. Since the position of the blocking member in the track is unchanged, when the movable block 221 touches the first blocking member, the first blocking member causes the movable block 221 to move relative to the damper body 100 in the door closing direction until it moves to the movable component 220 and is in a locked state. During this process, the energy storage elastic member 210 gradually stores energy; when the first clamping member 321 is blocked by the second blocking member in the track, the first clamping member 321 moves relative to the damper body 100 in the door closing direction. Due to the action of the buffer member, the door body opens slowly. The limiting elastic member 324 can limit the first clamping member 321 from moving to the extreme position relative to the damper body 100, so that the first clamping member 321 can continue to move a distance in the door closing direction when it is subjected to external force and overcomes the limiting force of the limiting elastic member 324. When the user needs to close the door, the user only needs to press the door body again along the door opening direction, and the damper body 100 will move slightly along the door opening direction for a distance. Correspondingly, the first clamp 321 drives the sliding block 310 to move toward the movable block 221 relative to the damper body 100. After the booster 311 on the sliding block 310 touches the movable block 221, the movable assembly 220 switches from the locked state to the released state, and the energy storage elastic member 210 releases energy to drive the door body to move in the door closing direction, and the door body slides out of the groove of the wall. After sliding out of the groove, the user can hold the door body to facilitate the user to manually close the door. Of course, the energy storage elastic member 210 can also be configured to release a large amount of energy, so that after releasing the energy, it can drive the door body to close by itself, and the user does not need to operate, which is more convenient to use.

[0044] In some embodiments, Figure 5-7 As shown, the movable stopper 221 is rotatably connected to the movable base 222, and a guide rod 2210 is provided on the movable stopper 221. The damper body 100 is provided with a guide groove 106 and a first arc groove 107, both of which are adapted to the guide rod 2210. Specifically, the guide rod 2210 can move in the guide groove 106 and the first arc groove 107. The guide groove 106 extends along the length direction of the damper body 100 to guide the movable stopper 221 to slide along the length direction of the damper body 100. One end of the first arc groove 107 is butted against one end of the guide groove 106, and the other end is bent downwardly from the guide groove 106 and gradually moves away from the guide groove 106.

[0045] Usually, the block in the track is arranged above the damper body 100. During the door opening process, the damper body 100 moves in the door opening direction, and the movable block 221 will touch the block, thereby driving the movable block 221 to move along the guide groove 106 relative to the damper body 100. When the guide rod 2210 moves from the guide groove 106 to the first arc groove 106, under the action of the block, the guide rod 2210 will move along the first arc groove 106 and make the movable block 221 rotate downward relative to the movable base 222, then the movable block 221 will no longer block the block in the track until the door body is fully opened. When the energy storage elastic member 210 releases energy, the energy storage elastic member 210 pushes the movable block 221 again, so that the guide rod 2210 re-enters the guide groove 106, and the movable block 221 rotates upward to reset so as to collide with the block next time.

[0046] Of course, in other embodiments, the movable stopper may also be slidably connected to the movable base, so that when the movable stopper moves to a specified position relative to the damper body, it can slide downward to avoid colliding with the stopper in the track.

[0047] Furthermore, the damper body 100 is also provided with a second arc groove 108 adapted to the guide rod 2210. Specifically, the guide rod 2210 can slide in the second arc groove 108, one end of the second arc groove 108 is butted against the end of the first arc groove 107 away from the guide groove 106, and the other end of the second arc groove 108 gradually approaches the end of the guide groove 106 away from the first arc groove 107. In the process of the guide rod 2210 moving along the guide groove 106 toward the second arc groove 108, the movable base 222 gradually applies a force to the energy storage elastic member 210, so that the energy storage elastic member 210 gradually stores energy. Since the energy storage elastic member 210 will apply a reverse force, that is, a force will be applied to the movable base 222 to move toward the end of the guide groove 106 away from the first arc groove 107. When the guide rod 2210 enters the second arc groove 108, the extension direction of the second arc groove 108 is in conflict with the force applied by the energy storage elastic member 210. The directions of the reverse forces are basically the same, so under the action of the energy storage elastic member 210, the guide rod 2210 will be restricted to the end of the second arc groove 108 away from the first arc groove 107, so that the movable component 220 is in a locked state; and when the guide rod 2210 moves from the second arc groove 108 to the first arc groove 107, the reverse force applied by the energy storage elastic member 210 causes the guide rod 2210 to move along the first arc groove 107 to the guide groove 106, so that the movable component 220 is in a released state.

[0048] In this embodiment, when the door is opened, the block in the track drives the guide rod 2210 on the movable block 221 to move along the guide groove 106 to the second arc groove 108, so that the movable assembly 220 is in a locked state, and the energy storage elastic member 210 stores energy. When the guide rod 2210 moves from the second arc groove 108 to the first arc groove 107, the movable assembly 220 is in a released state, and the energy storage elastic member 210 can release energy. Ensure that the energy storage elastic member 210 can effectively and stably store and release energy. The guide rod 2210 is driven to move from the second arc groove 108 to the first arc groove 107 by the booster 311.

[0049] In some embodiments, a receiving groove may be provided on the movable base 222, and the movable stopper 221 may be disposed in the receiving groove to reduce the overall volume and protect the movable stopper 221. Accordingly, a through groove may be provided on the side wall of the receiving groove, and the through groove may be provided in an arc shape relative to the rotation center of the movable stopper 221, so that the guide rod 2210 may pass through and move in the through groove.

[0050] In some embodiments, Figure 5 and Figure 7 As shown, a force-bearing inclined surface 2214 is provided on the movable stopper 221. When the force-bearing inclined surface 2214 is subjected to an external force applied along the length direction of the damper body 100, the guide rod 2210 can move from the second arc groove 108 to the first arc groove 107. In this way, the movable assembly 220 can be switched from a locked state to a released state. Specifically, the booster can collide with the force-bearing inclined surface 2214 on the movable stopper 221.

[0051] In some embodiments, Figure 8-10 As shown, a hook 230 is rotatably connected to the damper body 100, and a hook groove (not shown in the figure) adapted to the hook 230 is provided on the movable base 222. During the door opening process, the blocking member can drive the movable base 222 to gradually approach the hook 230, and the energy storage elastic member gradually stores energy. When the hook 230 is hooked in the hook groove, the energy storage elastic member cannot be reset, and the movable assembly is in a locked state; when the hook 230 is out of the hook groove, the movable assembly is in a released state, and the energy storage elastic member can be reset, thereby releasing energy.

[0052] A torsion spring can be arranged at the rotation axis position of the hook 230 and the damper body 100. Under the action of the torsion spring, the hook 230 can remain hooked in the hook groove, so that it is not easy to fall out of the hook groove, so that the movable component can stably maintain a locked state.

[0053] Further, the hook 230 is arranged on one side of the damper body 100, and a rotating member 231 is arranged on the hook 230. The side of the damper body 100 is provided with a hook groove 109 which penetrates and matches the rotating member 231, and the rotating member 231 passes through the hook groove 109. When the rotating member 231 is subjected to an external force applied along the length direction of the damper body 100, the rotating member 231 can drive the hook 230 to rotate so that the hook 230 is out of the hook groove. Specifically, the rotating member 231 can be collided by the booster to make the hook 230 rotate. Since the rotating member 231 extends to the other side of the damper body 100, the sliding block of the above embodiment is also located on the other side of the damper body 100. In this way, the energy storage elastic member and the movable component can be arranged on one side of the damper body 100, and the buffer component can be arranged on the other side, so as to save space and avoid the damper body 100 from being too long.

[0054] In some embodiments, Figure 7 As shown, the movable block includes a block base 2211 and a bending piece 2212, one end of the block base 2211 is rotatably connected to one end of the bending piece 2212, and the other end is provided with a hook 2213, the other end of the bending piece 2212 is located below the hook 2213, and the hook 2213 is used to limit the end of the bending piece 2212 close to the hook 2213 from rotating toward the top of the hook 2213. In this way, when the block in the track moves from the side of the hook 2213 to the side where the block base 2211 and the bending piece 2212 are rotatably connected, due to the obstruction of the hook 2213, the entire movable block will be blocked by the block in the track, so that the movable component can move to a locked state. When the outer side surface of the end of the bending member 2212 close to the block base 2211 and rotatably connected to the bending member 2212 receives an external force, that is, when the block in the track moves from the side where the block base 2211 and the bending member 2212 are rotatably connected to the side of the hook member 2213, the end of the bending member 2212 close to the hook member 2213 can rotate downward of the hook member 2213, and the bending member 2212 does not collide with the block in the track, so that the damper body 100 can move in the door closing direction.

[0055] Further, in some embodiments, reference may be made to Figure 8 and Fig. 9 The bending part is integrally connected with the block base, and the connection between the two can be elastically bent, and the end of the bending part close to the hook part abuts against the hook part. When the end of the bending part close to the hook part rotates downward of the hook part, the bending part can be reset to abut against the hook part under the action of elastic force to ensure that the block in the track can collide with the bending part next time.

[0056] In other embodiments, Figure 7As shown, an abutting elastic member (not shown in the figure) is arranged below one end of the bending member 2212 close to the stopper base 2211, and the abutting elastic member abuts the bending member 2212 and the stopper base 2211 respectively. Under the elastic force of the abutting elastic member, one end of the bending member 2212 close to the hook member 2213 abuts the hook member 2213. When the end of the bending member 2212 close to the hook member 2213 rotates toward the bottom of the hook member 2213, the bending member 2212 can be reset to abut the hook member 2213 under the elastic force of the abutting elastic member, so as to ensure that the stopper in the track can collide with the bending member 2212 next time.

[0057] In some embodiments, Figure 5 As shown, the movable base 222 and the abutment portion 103 are respectively provided with sleeve rods 104 extending toward each other, and the energy storage elastic member 210 is an energy storage spring. The two ends of the energy storage spring are respectively sleeved on the movable base 222 and the sleeve rod 104 of the abutment portion 103. On the one hand, the sleeve rod 104 can guide the expansion and contraction of the energy storage spring so that the force of the energy storage spring remains parallel to the length direction of the damper body 100. On the other hand, it is also convenient for the installation of the energy storage spring.

[0058] In the above embodiment, the energy storage spring can store energy when it is compressed. Of course, the energy storage spring can also be arranged to store energy when it is stretched.

[0059] Furthermore, a sleeve structure 105 is provided on the damper body 100, and the energy storage spring passes through the sleeve structure 105 to further enhance the guiding effect on the energy storage spring. The sleeve structure 105 may be cylindrical, and the damper body 100 may include two parts, which enclose the sleeve structure 105. Figure 5 Only a part of the structure of the damper body 100 is shown.

[0060] In some embodiments, Fig.12 and Fig.13 As shown, the damper body 100 includes a middle partition portion 120 extending along its length direction, and the middle partition portion 120 can be in the shape of a partition. The buffer component is located on one side of the middle partition portion 120, and the energy storage elastic component, the movable component and the sliding block are located on the other side of the middle partition portion. In this way, the buffer component can avoid the energy storage elastic component, the movable component and the sliding block, and will not conflict with the energy storage elastic component, the movable component and the sliding block. The overall structural layout is more reasonable, and the stability of each component during operation is higher. At the same time, the sliding block 310 is closer to the movable component and is more likely to touch the movable block.

[0061] Furthermore, the side of the middle partition 120 is provided with a through-connection groove 121 that penetrates the middle partition and extends along the length direction of the damper body 100. A connecting rod 325 is fixed on the first clamp 321. The connecting rod 325 passes through the through-connection groove 121 and is connected to the sliding block 310. In this way, the sliding block 310 and the first clamp 321 can be linked in the length direction of the damper body 100. Compared with the connecting rod 325 crossing the middle partition 120 and connecting to the sliding block 310, the through-connection groove 121 can make the overall structure more compact and reduce the overall size of the damper. The through-connection groove 121 can guide the connecting rod 325 so that the connecting rod 325 keeps moving along the length direction of the damper body 100.

[0062] Usually, a slot is provided on the first clamp 321. During the door opening process, the stopper in the track can be inserted into the slot to keep the first clamp 321 and the stopper fixed. During the door closing process, the stopper needs to be removed from the slot so that the stopper does not block the movement of the first clamp 321. For this reason, the existing first clamp 321 is designed to be rotatable, and the stopper can be inserted into or removed from the slot by rotating the first clamp 321. In this regard, the sliding block 310 of this embodiment is provided with a connecting hole 312, and the connecting rod 325 is inserted into the connecting hole 312 and can rotate in the connecting hole 312, so that the first clamp 321 can rotate around the axis of the connecting hole 312. At the same time, this structure does not affect the linkage between the sliding block 310 and the first clamp 321 in the length direction of the damper body 100.

[0063] Of course, in some other embodiments, the buffer assembly and the sliding block 310 may be located on the same side of the middle partition portion 120. To this end, the movable assembly needs to have a transmission member passing through the middle partition portion 120 so that the sliding block 310 can trigger the transmission member and then trigger the movable assembly.

[0064] In some embodiments, Figure 2 As shown, the damper body 100 is provided with a first sliding groove 101 and a second sliding groove 102 both extending along the length direction of the damper body 100, and the first sliding groove 101 and the second sliding groove 102 are separated by a middle partition 120, that is, the middle partition 120 forms a side wall of the first sliding groove 101 and also forms a side wall of the second sliding groove 102. The buffer assembly 320 and the sliding block 310 are respectively arranged in the first sliding groove 101 and the second sliding groove 102, which can protect the buffer assembly 320 and the sliding block 310 and prevent the buffer assembly 320 and the sliding block 310 from being separated from the damper body 100.

[0065] Further, such as Figure 2 and Fig.13As shown, the sliding block 310 is provided with buffer pads 313 on both sides of the damper body 100 in the length direction. The buffer pads 313 provide buffer protection for the sliding block 310 to prevent the sliding block 310 from directly colliding with the inner wall of the second sliding groove and being damaged.

[0066] Furthermore, the inner wall of the second sliding groove 102 is provided with a guide groove 122 extending along the length direction of the damper body 100, and the side of the sliding block 310 is provided with a guide block 314 slidably matched with the guide groove 122. The sliding match between the guide block 314 and the guide groove 122 can guide the sliding block 310, so that the sliding block 310 can stably move along the length direction of the damper body 100.

[0067] In some embodiments, Fig.11 and Fig.13 As shown, the booster 311 is rod-shaped and extends outward along a preset door closing direction to ensure that the booster 311 can trigger the movable component.

[0068] In some embodiments, Fig.13 and Fig.14 As shown, the buffer assembly also includes a second clamp 326 and a tension spring 322, and both ends of the buffer and the tension spring 322 are respectively connected to the first clamp 321 and the second clamp 326 to form a bidirectional buffer, so that the buffer assembly can buffer the door body when closing and opening the door. The blocking block 323 is arranged between the first clamp 321 and the second clamp 326, and the blocking block 323 is connected to the second clamp 326 to move synchronously with the second clamp 326. Among them, the buffer can be a damping tube, which can be fixed in the blocking block 323.

[0069] The embodiment of the present invention also provides a matching structure of a damper and a track, such as Fig.15 As shown, the pocket door damper includes a track and any one of the above embodiments, the damper body 100 is arranged in the track and can slide along the track. In order to facilitate observation of the structure in the track, Fig.15 The track is removed. A first stopper 410 and a second stopper 420 are provided in the track. When the damper body 100 moves in the door opening direction, the first stopper 410 will block the movable stopper 221, thereby driving the movable stopper 221 to move relative to the damper body 100 in the door closing direction until the movable assembly is in a locked state, and the second stopper 420 will block the first clamping member 321, thereby driving the first clamping member 321 to move relative to the damper body 100 in the door closing direction until the booster is close to the movable stopper 221. When the user presses the door body again, the booster pushes the movable stopper 221, so that the movable assembly moves from the locked state to the released state, thereby automatically closing the door. For the specific description of the pocket door damper, please refer to the above embodiment, which will not be repeated here.

[0070] Among them, it can be configured that during the door opening process, the first stopper 410 first blocks the movable block 221, and the second stopper 420 then blocks the first clamping member 321, so that the movable component first enters the locked state, and the booster component then approaches the movable component that is already in the locked state, which can avoid conflict between the booster component and the movable component.

[0071] In some embodiments, a stopper fixing plate 430 may be installed in the track, and the first stopper 410 and the second stopper 420 may be fixed on the stopper fixing plate 430 .

[0072] The above contents are further detailed descriptions of the present invention in combination with specific implementation methods, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention.
