Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and in particular to a limit self-locking mechanism, a lifting wireless charger, and a smart table. Background Technology

[0002] With the rapid development of wireless charging technology, its application in consumer electronics, furniture, and office equipment is becoming increasingly widespread. Traditional wireless charging devices are usually fixed structures with non-adjustable charging panels. Users must precisely align their electronic devices with the charging area during use; otherwise, misalignment may lead to reduced charging efficiency or even failure to charge. Furthermore, fixed wireless chargers often protrude from the desktop when integrated, affecting aesthetics and ease of use, especially in scenarios requiring a flat surface (such as writing or dining).

[0003] Furthermore, existing smart tabletops or integrated charging devices often have limited functionality and lack adaptability to various scenarios, failing to simultaneously meet multiple usage needs such as charging, storage, and cup holders. Therefore, there is an urgent need for a compact, stable, self-locking lifting mechanism and supporting equipment that can be flexibly integrated into various smart furniture applications. Utility Model Content

[0004] Based on the above, this application provides a limit self-locking mechanism, a lifting wireless charger, and a smart table.

[0005] A self-locking limiting mechanism includes a fixed part, a movable part, a linkage part, and a transmission mechanism. The movable part and / or the linkage part are slidably connected or clearance-fitted with the fixed part in the vertical direction. The transmission mechanism includes a sliding part and a connecting rod, one end of which is connected to the sliding part, and the other end of which is hinged to the movable part. A first slide rail is provided on the side of the linkage part facing the movable part, and the sliding part is slidably connected to the first slide rail, which guides the sliding part to slide closer to or away from the fixed part. A locking groove or locking hole is provided on the side of the fixed part facing the linkage part, for embedding or passing through the sliding part to lock the position of the linkage part and retract. The distance between the movable part and the linkage part is reduced; the movable part and / or the linkage part are further provided with a limiting structure or a spring. The limiting structure is used to restrict the sliding part to slide within a set range, and the spring is used to apply elastic force to the sliding part and / or the connecting rod, pressing the movable part against the surface of the fixed part, so that the connecting rod is tilted towards the fixed part, and the angle between the force acting on the sliding part and the sliding tendency direction of the sliding part is always less than 90 degrees; the movable part is used to connect to an external power mechanism to drive the movable part to move up and down reciprocally in the vertical direction, and to drive the linkage part to move up and down reciprocally through the transmission part. In this embodiment, the sliding part can be a part of the connecting rod, located at the end of the connecting rod and integrally formed with the connecting rod. When the movable part moves upward and the sliding part has not yet reached the lock groove or lock hole, the fixed part, the movable part, and the connecting rod form a stable triangular structure, providing stable support for pushing the linkage part upward. When the sliding part reaches the lock groove or lock hole, under the influence of the inclined force direction, the sliding part will move towards the lock groove or lock hole to embed itself in it. During the process of the sliding part embedding itself in the lock groove or lock hole, the triangular structure formed by the fixed part, the movable part, and the connecting rod is destroyed and can no longer support the linkage part to continue moving upward. At this time, the position height of the linkage part remains unchanged, while the movable part can continue to move upward. In addition, because the sliding part is embedded in the lock groove or lock hole, the downward movement of the linkage part will be hindered by the sliding part and cannot move, thus keeping the position height of the linkage part unchanged, achieving the locking purpose.

[0006] In one embodiment, the first slide rail includes a first groove disposed on the linkage part, the opening of the first groove facing the side where the movable part is located, the transmission part passing through the groove and hinged to the movable part, and the width of the opening of the first groove is smaller than the width of the bottom or internal space of the first groove, so as to restrict the sliding part to slide within the internal space of the first groove and prevent it from passing through the groove. This allows the movable part to drive the linkage part to move via the transmission mechanism.

[0007] In one embodiment, the sliding portion includes a lock head for locking the position of the linkage portion by engaging with the lock groove or lock hole. In this embodiment, the lock head is part of the sliding portion and is fixedly connected to or integrally formed with the sliding portion.

[0008] In one embodiment, the limiting structure restricts the sliding part to the end of the first slide rail near the fixing member, thereby increasing the rigidity of the vertical connection between the movable part and the linkage part and reducing the magnitude of the relative movement distance offset between the movable part and the linkage part. That is, relative movement between the movable part and the linkage part only occurs when the sliding part is inserted into or disengaged from the lock groove or lock hole, with the distance decreasing or increasing. In other movement processes, it is desirable for the movable part to drive the linkage part to move synchronously.

[0009] In one embodiment, the first groove extends to the side of the linkage and communicates with the outside. In this embodiment, viewed from the side of the linkage, it is equivalent to having a groove hole, and the inner wall of the groove hole is the first groove.

[0010] In one embodiment, the first groove is a dovetail groove, and the sliding part is slidably connected to the dovetail groove;

[0011] In one embodiment, the first groove is a dovetail groove, and the sliding part is slidably connected to the first groove with the same cross-sectional shape and specifications.

[0012] In one embodiment, the upper end face of the movable part is provided with a plurality of limiting holes, and the lower end face of the linkage part is provided with a plurality of limiting posts. The limiting posts are inserted into the limiting holes and are slidably connected or clearance-fitted with the limiting holes. Alternatively, the upper end face of the movable part is provided with a plurality of limiting posts, and the lower end face of the linkage part is provided with a plurality of limiting holes. The limiting posts are inserted into the limiting holes and are slidably connected or clearance-fitted with the limiting holes. In this embodiment, the cooperation of the plurality of limiting holes and the plurality of limiting posts can fix the projected positions of the movable part and the linkage part in the vertical direction, reduce the adverse effects of misalignment on the transmission mechanism, and improve the stability of the transmission between the movable part and the linkage part.

[0013] In one embodiment, a plurality of the limiting holes are arranged in a circumferential direction on the movable part, and a plurality of the limiting posts are arranged in a circumferential direction on the linkage part, wherein the number of the limiting holes is greater than or equal to the number of the limiting posts.

[0014] In one embodiment, a plurality of the limiting holes are arranged circumferentially on the movable part and near the edge of the movable part. A plurality of limiting posts are arranged circumferentially on the linkage part and near the edge of the linkage part, and their positions correspond to the positions of the limiting holes to facilitate insertion into the limiting holes. The number of limiting holes is greater than or equal to the number of limiting posts.

[0015] In one embodiment, a second slide rail is further included; the second slide rail is vertically arranged and fixedly connected to or integrally formed with the fixed part, that is, the side of the fixed part facing the movable part is also vertically arranged with a second slide rail, and the side of the movable part facing the fixed part is also vertically arranged with a second slide groove, the second slide rail is embedded in the second slide groove and slidably connected in the vertical direction; the second slide rail is arranged below the lock groove or the lock hole, and the sliding part slides along the second slide rail in the vertical direction; the second slide rail is sloped relative to the fixed part, and the height of the slope gradually increases from top to bottom, so that the sliding part gradually moves away from or closer to the fixed part when sliding along the second slide rail, that is, the sliding part slides along the second slide rail while also sliding left and right along the first slide rail, presenting the sliding part moving closer to or away from the fixed part.

[0016] In one embodiment, the fixed part has a first limiting groove and a second limiting groove vertically arranged on the side facing the linkage part; the movable part has a first limiting protrusion vertically arranged on the side facing the fixed part, which engages with the first limiting groove and is slidably connected in the vertical direction; the linkage part has a second limiting protrusion vertically arranged on the side facing the fixed part, which engages with the second limiting groove and is slidably connected in the vertical direction; the upper end of the second limiting groove is higher than the upper end of the first limiting groove. In this embodiment, the limiting groove and the limiting protrusion are interchangeable, and the second limiting groove and the second limiting protrusion have the function of limiting the position height of the linkage part.

[0017] In one embodiment, the bottom ends of the first limiting groove and the second limiting groove are located on the same horizontal plane, and the length (same height) of the second limiting groove is greater than the length (same height) of the first limiting groove.

[0018] In one embodiment, the sliding part includes a pulley for sliding along the first slide rail to reduce sliding resistance and / or sliding noise.

[0019] In one embodiment, the outer surface of the pulley is made of plastic or rubber.

[0020] In one embodiment, the diameter of the pulley is greater than or equal to the height of the lock groove or lock hole.

[0021] In one embodiment, the diameter of the pulley is 1.1-1.5 times the height of the lock groove or lock hole, so as to lock the linkage by embedding the pulley into the lock groove or lock hole.

[0022] In one embodiment, the transmission part is positioned near the edge of the movable part.

[0023] The aforementioned limiting self-locking mechanism, through the fixed part, the movable part, and the connecting rod forming a stable triangular structure, provides stable support for the movable part to push the linkage part upward. By providing a locking groove or hole on the fixed part that allows the sliding part to embed, the sliding part slides laterally when passing through the locking groove or hole, disrupting the triangular support structure and preventing the linkage part from moving with the movable part, thus stabilizing the height of the linkage part. Furthermore, once the sliding part is embedded in the locking groove or hole, it blocks the downward movement of the linkage part, locking its position and achieving the limiting self-locking purpose of the mechanism. When the movable part moves downward, the position of the linkage part does not move with the movable part until the sliding part disengages from the locking groove or hole. In other words, this limiting self-locking mechanism allows the movable part and the linkage part to move relative to each other in the vertical direction during the locking process, causing the distance between them to change within a set range.

[0024] Based on the above, this application also provides a pop-up wireless charger.

[0025] A lifting wireless charger includes the limiting self-locking mechanism described in any of the above embodiments; a boss is provided at the upper end of the movable part, and a wireless charging transmitter is installed in the boss; the boss and the linkage part are slidably connected or clearance-fitted in the vertical direction, so that the boss can generate relative displacement with the linkage part in the vertical direction, so that the boss is higher than, equal to or lower than the linkage part.

[0026] In one embodiment, when the sliding part disengages from the lock groove or lock hole, the height of the boss is set to be equal to the height of the linkage part, so that when the sliding part disengages from the lock groove or lock hole, the upper end face of the boss is flush with the upper end face of the linkage part. The upper end face of the linkage part is generally planar. This configuration ensures that when the sliding part is embedded in the lock groove or lock hole, the height of the boss is higher than the height of the linkage part, that is, the upper end face of the boss is higher than the upper end face of the linkage part.

[0027] In one embodiment, when the sliding part disengages from the lock groove or lock hole, the height of the boss is set lower than the height of the linkage part, and the height difference is equal to the change in distance between the movable part and the linkage part. This ensures that when the sliding part disengages from the lock groove or lock hole, the upper surface of the boss is lower than the upper surface of the linkage part. The upper surface of the linkage part is generally planar. This configuration ensures that when the sliding part is embedded in the lock groove or lock hole, the height of the boss is equal to the height of the linkage part, i.e., the upper surface of the boss is equal to the upper surface of the linkage part.

[0028] In one embodiment, when the sliding part disengages from the lock groove or lock hole, the height of the boss is set lower than the height of the linkage part, and the height difference is less than the distance change between the movable part and the linkage part. This ensures that when the sliding part disengages from the lock groove or lock hole, the upper surface of the boss is lower than the upper surface of the linkage part. The upper surface of the linkage part is generally planar. This configuration ensures that when the sliding part is embedded in the lock groove or lock hole, the height of the boss is higher than the height of the linkage part, i.e., the upper surface of the boss is higher than the upper surface of the linkage part.

[0029] In one embodiment, when the sliding part disengages from the lock groove or lock hole, the height of the boss is set lower than the height of the linkage part, and the height difference is greater than the change in distance between the movable part and the linkage part. This ensures that when the sliding part disengages from the lock groove or lock hole, the upper surface of the boss is lower than the upper surface of the linkage part. The upper surface of the linkage part is generally planar. This configuration ensures that when the sliding part is embedded in the lock groove or lock hole, the height of the boss is still less than the height of the linkage part, i.e., the upper surface of the boss is lower than the upper surface of the linkage part. During the overall change of the sliding part embedding into the lock groove or lock hole, the height difference between the linkage part and the boss decreases.

[0030] In one embodiment, when the sliding part is embedded in the lock groove or lock hole, the boss is higher than the linkage part.

[0031] In one embodiment, the upper surface of the linkage is entirely planar. When the sliding part disengages from the lock groove or lock hole, the distance from the upper surface of the linkage to the hinge axis connecting the connecting rod and the movable part is the same as the distance from the upper surface of the boss to the hinge axis. When the sliding part is inserted into the lock groove or lock hole, the distance from the upper surface of the linkage to the hinge axis connecting the connecting rod and the movable part is less than the distance from the upper surface of the boss to the hinge axis. In this embodiment, the distance between the boss surface and the hinge axis remains constant, while the distance from the upper surface of the linkage to the hinge axis changes with the vertical distance between the movable part and the linkage as the sliding part is inserted into or disengaged from the lock groove or lock hole.

A fan is provided inside the air outlet to discharge the air inside the cylindrical structure from the air outlet and to draw in fresh air from the air inlet to dissipate heat from the electronic components installed in the fixing part of the cylindrical structure.

[0044] In one embodiment, the fixing part is generally cylindrical.

[0045] In one embodiment, the fixing part includes a plurality of vertically arranged fixing plates, which are spaced apart in the circumferential direction to form the installation space and range of the movable part and the linkage part.

[0046] In one embodiment, a limit switch and a trigger are also included. The limit switch is used to control the start and stop of the drive motor, and the trigger is disposed on the transmission rod or the movable part to trigger the limit switch to act, thereby controlling the position where the movable part stops when it moves relative to the fixed part.

[0056] The aforementioned lift-up wireless charger, through a limiting self-locking mechanism, allows the protrusion on which the wireless charger is mounted to move relative to the linkage in the vertical direction. This allows the protrusion to be higher than, equal to, or lower than the linkage, meaning the protrusion can be higher than the linkage.

[0093] In this patent document, the following is discussed Figure 1-15 The various embodiments used to describe the principles or methods of this disclosure are for illustrative purposes only and should not be construed as limiting the scope of this disclosure in any way. Preferred embodiments of this disclosure will be described below with reference to the accompanying drawings. In the following description, detailed descriptions of well-known functions or configurations will be omitted to avoid obscuring the subject matter of this disclosure with unnecessary detail. Furthermore, the terminology used herein will be defined according to the functional definition of this utility model. Therefore, the terminology may vary depending on the intention or usage of the user or operator. Consequently, the terminology used herein must be understood based on the descriptions made herein.

[0094] A self-locking limit mechanism, such as Figure 1As shown, the device comprises a fixed part 100, a movable part 200, a linkage part 300, and a transmission mechanism 400. The movable part 200 and / or the linkage part 300 are slidably connected to or clearance-fitted with the fixed part 100 in the vertical direction. The transmission mechanism 400 includes a sliding part 420 and a connecting rod 410, one end of which is connected to the sliding part 420, and the other end is hinged to the movable part 200. A first slide rail is provided on the side of the linkage part 300 facing the movable part 200, and the sliding part 420 is slidably connected to the first slide rail. The first slide rail is used to guide the sliding part 420 to slide closer to or away from the fixed part 100. A locking groove 110 or a locking hole is provided on the side of the fixed part 100 facing the linkage part 300, which is used to engage or pass through the sliding part 420 to lock the position of the linkage part 300 and reduce the distance between the movable part 200 and the linkage part 300. The movable part 200 and / or the linkage part 300 are also provided with a limiting structure 311 or a spring. The limiting structure 311 is used to restrict the sliding part 420 to slide within a set range. The spring is used to apply elastic force to the sliding part 420 and / or the connecting rod 410, pressing the sliding part 420 against the surface of the fixed part 100, so that the connecting rod 410 is inclined towards the fixed part 100, and the angle between the force acting on the sliding part 420 and the sliding tendency direction of the sliding part 420 is always less than 90 degrees. The movable part 200 is used to connect to an external power mechanism to drive the movable part 200 to move up and down reciprocally in the vertical direction, and to drive the linkage part 300 to move up and down reciprocally through the transmission part. In this embodiment, the sliding part 420 may be a part of the connecting rod 410, located at the end of the connecting rod 410 and integrally formed with the connecting rod 410. When the movable part 200 moves upward and the sliding part 420 has not yet reached the lock groove 110 or the lock hole, the fixed part 100, the movable part 200 and the connecting rod 410 form a stable triangular structure, which provides stable support for pushing the linkage part 300 to move upward. When the sliding part 420 reaches the lock groove 110 or the lock hole, the sliding part 420 will move towards the lock groove 110 or the lock hole under the influence of the inclined force direction to embed into the lock groove 110 or the lock hole. During the process of the sliding part 420 embedding into the lock groove 110 or the lock hole, the triangular structure formed by the fixed part 100, the movable part 200 and the connecting rod 410 is destroyed and cannot support the linkage part 300 to continue to move upward. At this time, the position height of the linkage part 300 remains unchanged, while the movable part 200 can continue to move upward. Furthermore, since the sliding part 420 is embedded in the lock groove 110 or the lock hole, the downward movement of the linkage part 300 will be hindered by the sliding part 420 and will not be able to move, thereby keeping the position height of the linkage part 300 unchanged and achieving the purpose of locking.

[0095] In one embodiment, such as Figure 2As shown, the first slide rail includes a first slide groove 310 disposed on the linkage part 300. The opening of the first slide groove 310 faces the side where the movable part 200 is located. The transmission part passes through the opening and is hinged to the movable part 200. The width of the opening of the first slide groove 310 is smaller than the width of the bottom or the internal space of the first slide groove 310, so as to restrict the sliding part 420 to slide within the internal space of the first slide groove 310 and prevent it from passing through the opening. This allows the movable part 200 to drive the linkage part 300 to move via the transmission mechanism 400.

[0096] In one embodiment, the sliding part 420 includes a lock head (not shown) for locking the position of the linkage part 300 by engaging with the lock groove 110 or the lock hole. In this embodiment, the lock head is part of the sliding part 420 and is fixedly connected to or integrally formed with the sliding part 420.

[0097] In one embodiment, such as Figure 2 As shown, the limiting structure 311 restricts the sliding part 420 to the end of the first slide rail near the fixing member, thereby increasing the rigidity of the vertical connection between the movable part 200 and the linkage part 300 and reducing the magnitude of the relative movement distance offset between the movable part 200 and the linkage part 300. That is, relative movement between the movable part 200 and the linkage part 300 only occurs when the sliding part 420 is inserted into or disengaged from the lock groove 110 or lock hole, and the distance between them decreases or increases. In other movement processes, it is desirable that the movable part 200 can drive the linkage part 300 to move synchronously.

[0098] In one embodiment, such as Figure 1 Figure 2 As shown, the first groove 310 extends to the side of the linkage 300 and communicates with the outside. In this embodiment, viewed from the side of the linkage 300, it is equivalent to having a groove hole, and the inner wall of the groove hole is the first groove 310.

[0099] In one embodiment, the first groove 310 is a dovetail groove (not shown in the figure), and the sliding part 420 is slidably connected to the dovetail groove.

[0100] In one embodiment, the first groove 310 is a dovetail groove, and the sliding part 420 and the first groove 310 are slidably connected with each other using the same cross-sectional shape and specifications.

[0101] In one embodiment, such as Figure 1 Figure 2As shown, the upper end face of the movable part 200 is provided with a plurality of limiting holes 210, and the lower end face of the linkage part 300 is provided with a plurality of limiting posts 320. The limiting posts 320 are inserted into the limiting holes 210 and are slidably connected or clearance-fitted with the limiting holes 210. Alternatively, the upper end face of the movable part 200 is provided with a plurality of limiting posts 320, and the lower end face of the linkage part 300 is provided with a plurality of limiting holes 210. The limiting posts 320 are inserted into the limiting holes 210 and are slidably connected or clearance-fitted with the limiting holes 210. In this embodiment, the cooperation of the plurality of limiting holes 210 and the plurality of limiting posts 320 can fix the projected position of the movable part 200 and the linkage part 300 in the vertical direction, reduce the adverse effects of misalignment on the transmission mechanism 400, and improve the stability of the transmission between the movable part 200 and the linkage part 300.

[0102] In one embodiment, such as Figure 2 As shown, a number of limiting holes 210 are arranged in a circumferential direction on the movable part 200, and a number of limiting posts 320 are arranged in a circumferential direction on the linkage part 300, and the number of limiting holes 210 is greater than or equal to the number of limiting posts 320.

[0103] In one embodiment, such as Figure 2 As shown, a plurality of limiting holes 210 are arranged circumferentially on the movable part 200 and are located near the edge of the movable part 200. A plurality of limiting posts 320 are arranged circumferentially on the linkage part 300 and are located near the edge of the linkage part 300, and their positions correspond to the limiting positions to facilitate insertion into the limiting holes 210. The number of limiting holes 210 is greater than or equal to the number of limiting posts 320.

[0104] In one embodiment, such as Figure 1 As shown, it also includes a second slide rail 120. The second slide rail 120 is vertically arranged and is fixedly connected to or integrally formed with the fixed part 100. That is, the second slide rail 120 is vertically arranged on the side of the fixed part 100 facing the movable part 200, and the movable part 200 is vertically arranged on the side facing the fixed part 100. The second slide rail 120 is embedded in the second slide groove 220 and slidably connected in the vertical direction. The second slide rail 120 is located below the lock groove 110 or lock hole, and the sliding part 420 slides along the second slide rail 120 in the vertical direction. The second slide rail 120 is sloped relative to the fixed part 100, and the height of the slope gradually increases from top to bottom, so that the sliding part 420 gradually moves away from or closer to the fixed part 100 when sliding along the second slide rail 120. That is, while sliding along the second slide rail 120, the sliding part 420 also slides left and right along the first slide rail, presenting that the sliding part 420 moves closer to or away from the fixed part 100.

[0105] In one embodiment, such as Figure 1As shown, the fixed part 100 has a first limiting groove 131 and a second limiting groove 132 vertically arranged on the side facing the linkage part 300. The movable part 200 has a first limiting protrusion 230 vertically arranged on the side facing the fixed part 100, which engages with the first limiting groove 131 and is slidably connected in the vertical direction. The linkage part 300 has a second limiting protrusion 330 vertically arranged on the side facing the fixed part 100, which engages with the second limiting groove 132 and is slidably connected in the vertical direction. The upper end of the second limiting groove 132 is higher than the upper end of the first limiting groove 131. In this embodiment, the limiting groove and the limiting protrusion can be interchanged, and the second limiting groove 132 and the second limiting protrusion 330 have the function of limiting the position height of the linkage part 300.

[0106] In one embodiment, such as Figure 1 As shown, the bottom ends of the first limiting groove 131 and the second limiting groove 132 are located on the same horizontal plane, and the length (same height) of the second limiting groove 132 is greater than the length (same height) of the first limiting groove 131.

[0107] In one embodiment, such as Figure 2 Figure 4 As shown, the sliding part 420 includes a pulley 421 for sliding along the first slide rail, which is used to reduce sliding resistance and / or sliding noise.

[0108] In one embodiment, the outer surface of pulley 421 is made of plastic or rubber.

[0109] In one embodiment, the diameter of pulley 421 is greater than or equal to the height of lock groove 110 or lock hole.

[0110] In one embodiment, the diameter of the pulley 421 is 1.1-1.5 times the height of the lock groove 110 or the lock hole, so that the pulley 421 can be inserted into the lock groove 110 or the lock hole to lock the linkage 300.

[0111] In one embodiment, such as Figure 1 Figure 2 As shown, the transmission part is positioned near the edge of the movable part 200.

[0112] The aforementioned limiting self-locking mechanism, through the fixed part 100, the movable part 200, and the connecting rod 410 forming a stable triangular structure, provides stable support for the movable part 200 to push the linkage part 300 upward. By providing a locking groove 110 or locking hole on the fixed part 100 that allows the sliding part 420 to be inserted, the sliding part 420 slides laterally when passing through the locking groove 110 or locking hole, disrupting the triangular support structure and preventing the linkage part 300 from moving with the movable part 200, thus stabilizing the position height of the linkage part 300. Furthermore, after the sliding part 420 is inserted into the locking groove 110 or locking hole, it blocks the downward movement path of the linkage part 300, locking the position of the linkage part 300 and achieving the limiting self-locking purpose of the mechanism. And when the movable part 200 moves downward, before the sliding part 420 disengages from the lock groove 110 or lock hole, the position of the linkage part 300 does not move with the movement of the movable part 200. That is, the limiting self-locking mechanism can make the movable part 200 and the linkage part 300 move relative to each other in the vertical direction during the locking process, so that the distance between them changes within a set range.

[0113] Based on the above, this application also provides a pop-up wireless charger.

[0114] A type of pop-up wireless charger, such as Figure 1 As shown, this includes the limiting self-locking mechanism in any of the above embodiments. A boss is provided at the upper end of the movable part 200, and a wireless charging transmitter 11 is installed inside the boss. The boss and the linkage part 300 are slidably connected or clearance-fitted in the vertical direction, so that the boss can generate relative displacement with the linkage part 300 in the vertical direction, making the boss higher than, equal to, or lower than the linkage part 300.

[0115] In one embodiment, such as Figure 1 As shown, when the sliding part 420 disengages from the lock groove 110 or the lock hole, the height of the boss is set to be equal to the height of the linkage part 300, so that when the sliding part 420 disengages from the lock groove 110 or the lock hole, the upper end surface of the boss is flush with the upper end surface of the linkage part 300. The upper end surface of the linkage part 300 is generally planar. With this configuration, when the sliding part 420 is inserted into the lock groove 110 or the lock hole, the height of the boss is higher than the height of the linkage part 300, that is, the upper end surface of the boss is higher than the upper end surface of the linkage part 300.

[0116] In one embodiment, such as Figure 1As shown, when the sliding part 420 disengages from the lock groove 110 or the lock hole, the height of the boss is set lower than the height of the linkage part 300, and the height difference is equal to the change in distance between the movable part 200 and the linkage part 300. This ensures that when the sliding part 420 disengages from the lock groove 110 or the lock hole, the upper surface of the boss is lower than the upper surface of the linkage part 300. The upper surface of the linkage part 300 is generally planar. This arrangement ensures that when the sliding part 420 is inserted into the lock groove 110 or the lock hole, the height of the boss is equal to the height of the linkage part 300, that is, the upper surface of the boss is equal to the upper surface of the linkage part 300.

[0117] In one embodiment, such as Figure 1 As shown, when the sliding part 420 disengages from the lock groove 110 or the lock hole, the height of the boss is set lower than the height of the linkage part 300, and the height difference is less than the distance change between the movable part 200 and the linkage part 300. This ensures that when the sliding part 420 disengages from the lock groove 110 or the lock hole, the upper surface of the boss is lower than the upper surface of the linkage part 300. The upper surface of the linkage part 300 is generally planar. This arrangement ensures that when the sliding part 420 is inserted into the lock groove 110 or the lock hole, the height of the boss is higher than the height of the linkage part 300, that is, the upper surface of the boss is higher than the upper surface of the linkage part 300.

[0118] In one embodiment, such as Figure 1 As shown, when the sliding part 420 disengages from the lock groove 110 or the lock hole, the height of the boss is set lower than the height of the linkage part 300, and the height difference is greater than the change in distance between the movable part 200 and the linkage part 300. This ensures that when the sliding part 420 disengages from the lock groove 110 or the lock hole, the upper surface of the boss is lower than the upper surface of the linkage part 300. The upper surface of the linkage part 300 is generally planar. This arrangement ensures that when the sliding part 420 is inserted into the lock groove 110 or the lock hole, the height of the boss is still less than the height of the linkage part 300, meaning the upper surface of the boss is lower than the upper surface of the linkage part 300. During the overall change of the sliding part 420 inserting into the lock groove 110 or the lock hole, this directly manifests as a decrease in the height difference between the linkage part 300 and the boss.

[0119] In one embodiment, such as Figure 13 As shown, when the sliding part 420 is embedded in the lock groove 110 or the lock hole, the boss is higher than the linkage part 300.

[0120] In one embodiment, such as Figure 1 Figure 2As shown, the upper surface of the linkage part 300 is generally planar. When the sliding part 420 disengages from the lock groove 110 or the lock hole, the distance from the upper surface of the linkage part 300 to the hinge axis connecting the connecting rod 410 and the movable part 200 is the same as the distance from the upper surface of the boss to the hinge axis. When the sliding part 420 is inserted into the lock groove 110 or the lock hole, the distance from the upper surface of the linkage part 300 to the hinge axis connecting the connecting rod 410 and the movable part 200 is less than the distance from the upper surface of the boss to the hinge axis. In this embodiment, the distance between the boss surface and the hinge axis remains constant, while the distance from the upper surface of the linkage part 300 to the hinge axis changes with the vertical distance between the movable part 200 and the linkage part 300 as the sliding part 420 is inserted into or disengaged from the lock groove 110 or the lock hole.

[0121] In one embodiment, such as Figure 1 Figure 3 As shown, it also includes a transmission rod 270, a bottom cover 500, and a drive motor 610. The bottom cover 500 is located below the movable part 200 and is fixedly connected to or integrally formed with the fixed part 100. The transmission rod 270 is vertically arranged and is fixedly connected to or integrally formed with the movable part 200. The drive motor 610 is fixedly connected to the bottom cover 500 or the fixed part 100, and is driven by the transmission rod 270 through gear transmission or screw transmission to convert the rotational motion of the output shaft of the drive motor 610 into the linear motion of the movable part 200.

[0122] Alternatively, the transmission rod 270 is vertically arranged and threadedly connected to the movable part 200. The drive motor 610 is fixedly connected to the bottom cover 500 or the fixed part 100. The rotor is directly or through the transmission mechanism 400 connected to the transmission rod 270, so as to convert the rotational motion of the output shaft of the drive motor 610 into the rotational motion of the transmission rod 270, and then into the up-and-down motion of the movable part 200.

[0123] Alternatively, the transmission rod 270 is vertically arranged and fixedly connected to or integrally formed with the bottom cover 500 or the fixed part 100. The drive motor 610 is fixedly connected to the movable part 200 and is driven by the transmission rod 270 through gear transmission or screw transmission, so as to convert the rotational motion of the output shaft of the drive motor 610 into the linear motion of the movable part 200. In this embodiment, the transmission rod 270 and the movable part 200 are connected by a threaded transmission, i.e., a lead screw transmission connection.

[0124] In one embodiment, such as Figure 3As shown, the transmission rod 270 is vertically arranged and threadedly connected to the bottom cover 500 or the fixed part 100. The drive motor 610 is fixedly connected to the movable part 200. The rotor is directly connected to the transmission rod 270 or through the transmission mechanism 400 to convert the rotational motion of the output shaft of the drive motor 610 into the rotational motion of the transmission rod 270, and then into the up-and-down motion of the movable part 200. In this embodiment, the threaded connection between the transmission rod 270 and the bottom cover 500 or the fixed part 100 is a lead screw drive connection.

[0125] In one embodiment, such as Figure 5 Figure 6 As shown, the bottom cover 500 is also provided with a motor mounting base 530 for mounting the drive motor 610 and a fan mounting base 540 for mounting the fan 620.

[0126] In one embodiment, such as Figure 1 Figure 2 As shown, a through hole 340 is provided in the middle of the linkage part 300, and the boss is slidably connected to or clearance-fitted with the through hole 340.

[0127] In one embodiment, such as Figure 1 Figure 2 As shown, the through hole 340 is a circular hole, and the boss is a cylindrical boss, with the inner diameter of the circular hole being greater than or equal to the outer diameter of the boss. Alternatively, the through hole 340 is an elliptical hole, and the boss is an elliptical cylindrical boss. Alternatively, the through hole 340 is a polygonal hole, and the boss is a polygonal prism cylindrical boss, with the number of edges being the same as the number of sides of the polygonal hole.

[0128] In one embodiment, the through hole 340 is rectangular, and the boss is a quadrangular prism boss.

[0129] In one embodiment, such as Figure 1 Figure 2 As shown, the linkage part 300 is generally circular, and the through hole 340 in the middle is a round hole.

[0130] In one embodiment, the projection of the linkage 300 in the vertical direction is a circular polygon, and the through hole 340 in the middle is a circular hole or a polygonal hole.

[0131] In one embodiment, such as Figure 1 As shown, the boss includes a first mounting base 251 and a cap 252. The first mounting base 251 is fixedly connected to the movable part 200 or integrally formed, and the cap 252 is detachably fixedly connected to the movable part 200. The cap 252 and the first mounting base 251 enclose an installation space for installing the wireless charging transmitter 11.

[0132] In one embodiment, the transmitting coil of the wireless charging transmitter 11 is fixedly connected to the top inside the cap 252 or to the first mounting base 251.

[0133] In one embodiment, such as Figure 8 Figure 9 As shown, the outer edge of the boss is provided with several ventilation holes 253 that communicate with the cavity inside the boss to help the wireless charging transmitter 11 dissipate heat.

[0134] In one embodiment, such as Figure 9 As shown, a water storage tank 260 is also provided inside the boss. The water storage tank 260 is located below the ventilation hole 253 to receive the liquid flowing in from the ventilation hole 253.

[0135] In one embodiment, such as Figure 1 As shown, the boss includes a first mounting base 251 and a cap 252. The first mounting base 251 is fixedly connected to the movable part 200 or integrally formed, and the cap 252 is detachably fixedly connected to the movable part 200. The cap 252 and the first mounting base 251 enclose an installation space for installing the wireless charging transmitter 11.

[0136] In one embodiment, such as Figure 9 As shown, the water storage tank 260 is located inside the cap, and / or, as... Figure 10 As shown, it is mounted on the first mounting base 251.

[0137] In one embodiment, such as Figure 1 Figure 2 As shown, the fixing part 100 has an overall cylindrical structure, and an air inlet 240 is also provided on the side wall, such as Figure 5 Figure 7 As shown, the bottom cover 500 has an air outlet 520. A fan 620 is installed inside the air outlet 520 to discharge the air inside the cylindrical structure from the air outlet 520 and to draw in fresh air from the air inlet 240 to dissipate heat from the electronic components installed in the cylindrical structure fixing part 100.

[0138] In one embodiment, such as Figure 1 Figure 2 As shown, the active part 200 has an overall cylindrical structure.

[0139] In one embodiment, the fixing part 100 includes a plurality of vertically arranged fixing plates, which are spaced apart in the circumferential direction to form the installation space and range of the movable part 200 and the linkage part 300.

[0140] In one embodiment, such as Figure 3 Figure 5 Figure 6As shown, it also includes a limit switch and a triggering part. The limit switch is used to control the start and stop of the drive motor 610. The triggering part is set on the transmission rod 270 or the movable part 200 and is used to trigger the limit switch to act, thereby controlling the position where the movable part 200 stops when it moves relative to the fixed part 100.

[0141] In one embodiment, such as Figure 5 Figure 6 As shown, it includes a first limit switch 631, a second limit switch 632 and a third limit switch 633 fixedly connected to the fixed part 100 and / or the bottom cover 500, and a first trigger part 271, a second trigger part 272 and a third trigger part 273 fixedly connected to or integrally formed with the transmission rod 270 and / or the movable part 200.

[0142] The first limit switch 631 is disposed on the vertical movement path of the first trigger part 271, the second limit switch 632 is disposed on the vertical movement path of the second trigger part 272, and the third limit switch 633 is disposed on the vertical movement path of the third trigger part 273. When the position of the movable part 200 is lowered to the bottom, the distance between the first trigger part 271 and the first limit switch 631 is less than the distance between the second trigger part 272 and the second limit switch 632, and the distance between the second trigger part 272 and the second limit switch 632 is less than the distance between the third trigger part 273 and the third limit switch 633.

[0143] When the first trigger 271 activates the first limit switch 631, the movable part 200 is positioned at the bottom. When the second trigger 272 activates the second limit switch 632, the sliding part 420 reaches the lower edge of the lock groove 110 or lock hole. When the third trigger 273 activates the third limit switch 633, the sliding part 420 is engaged in the lock groove 110 or lock hole, and the position of the linkage part 300 and the fixed part 100 is locked. Between the activation of the second limit switch 632 by the second trigger 272 and the activation of the third limit switch 633 by the third trigger 273, the position height of the linkage part 300 is not affected by the change in the position height of the movable part 200.

[0149] In one embodiment, a magnetic component (not shown in the figure) is also provided inside the boss to facilitate the alignment between the wireless charger transmitter and the receiver and to provide a certain degree of fixation during charging.

[0150] The aforementioned lift-up wireless charger, through a limiting self-locking mechanism, allows the protrusion on which the wireless charger is mounted and the linkage part 300 to move relative to each other in the vertical direction. This allows the protrusion to be higher than, equal to, or lower than the linkage part 300, meaning the protrusion can be higher than the linkage part 300. This elevates the wireless charging receiver, such as a mobile phone, placed on the protrusion, preventing the camera or other electronic components from affecting the wireless charging gap and ensuring a tighter fit between the wireless charging transmitter and receiver. Alternatively, the protrusion can be made equal to or lower than the linkage part 300, resulting in a flat surface or a recessed center, facilitating applications in other scenarios, such as placing a water cup or wirelessly charging smaller electronic products like watches.

[0151] Based on the above-mentioned content, this application also provides a smart table.

[0173] In one embodiment, such as Figure 9 As shown, the water storage tank 260 is located inside the cap, and / or, as... Figure 10 As shown, it is mounted on the first mounting base 251.

[0174] The aforementioned smart tabletop, through a limiting self-locking mechanism, allows the protrusion with the wireless charger mounted on it to move relative to the linkage part 300 in the vertical direction. This allows the protrusion to be higher than, equal to, or lower than the linkage part 300, meaning the protrusion can be higher than the linkage part 300. This elevates the wireless charging receiver, such as a mobile phone, placed on the protrusion, preventing the camera or other electronic components from affecting the wireless charging gap and ensuring a tighter fit between the wireless charging transmitter and receiver. Alternatively, the protrusion can be made equal to or lower than the linkage part 300, resulting in a flat surface or a recessed center, facilitating other applications such as placing water cups or wirelessly charging smaller electronic products like watches.

[0175] Based on the above, this application also provides a cup holder.

[0176] A type of cup holder, such as Figure 11 As shown, the device includes a housing 700, a cup holder, a movable part 200, and a driving mechanism.

The cup holder is the fixed part 100 in any of the above embodiments.

[0177] In one embodiment, such as Figure 1 As shown, a boss is provided on the upper surface of the movable part 200. The boss has a hollow structure and is used to install the wireless charging transmitter 11. When placing a wireless charging receiver, the boss raises the placed wireless charging receiver.

[0178] In one embodiment, the boss and the movable part 200 are integrally formed.

[0179] In one embodiment, such as Figure 3 Figure 5 Figure 6 As shown, the drive mechanism includes a transmission rod 270 and a drive motor 610. The transmission rod 270 is vertically arranged and is fixedly connected to or integrally formed with the movable part 200. The drive motor 610 is fixedly connected to the housing 700 or the cup and is transmitted to the transmission rod 270 through gear transmission or screw transmission, so as to convert the rotational motion of the output shaft of the drive motor 610 into the linear motion of the movable part 200.

[0180] Alternatively, the transmission rod 270 is vertically arranged and threadedly connected to the movable part 200. The drive motor 610 is fixedly connected to the housing 700 or the cup, and the rotor is connected to the transmission rod 270 to convert the rotational motion of the output shaft of the drive motor 610 into the rotational motion of the transmission rod 270, and then into the up-and-down motion of the movable part 200 through threaded transmission.

[0181] In one embodiment, such as Figure 3 As shown, the transmission rod 270 is provided with a rack 274 in the vertical direction, such as... Figure 1 Figure 5 Figure 6 As shown, the output shaft of the drive motor 610 is equipped with a gear 611, which has the same module as the rack 274, and the two mesh with each other for transmission. The rack 274 is fixedly connected to the transmission rod 270 or integrally formed. The gear 611 is fixedly connected to the output shaft of the drive motor 610 or integrally formed.

[0182] In one embodiment, such as Figure 5 Figure 6 As shown, it also includes a limit switch and a triggering part. The limit switch is used to control the start and stop of the drive motor 610. The triggering part is set on the transmission rod 270 or the movable part 200 and is used to trigger the limit switch to act, thereby controlling the position of the movable part 200 inside the cup.

When the movable part 200 is lowered to its lowest position, the distance between the first trigger part 271 and the first limit switch 631 is less than the distance between the second trigger part 272 and the second limit switch 632, and the distance between the second trigger part 272 and the second limit switch 632 is less than the distance between the third trigger part 273 and the third limit switch 633. Furthermore, when the first trigger 271 triggers the first limit switch 631, the movable part 200 is positioned at the bottom of the cup. When the third trigger 273 triggers the third limit switch 633, the upper surface of the movable part 200 and the upper surface of the housing 700 are located in the same plane. In this embodiment, since the boss is provided on the upper surface of the movable part 200, when the upper surface of the movable part 200 and the upper surface of the housing 700 are in the same plane, the upper surface of the boss is higher than the upper surface of the housing 700. This allows the wireless charging receiver placed on the boss to be raised a certain distance from the upper surface of the housing 700, preventing the contact between the wireless charging part and components such as the camera of a wall-mounted smartphone or other wireless charging receiver from being too tight.

[0184] In one embodiment, such as Figure 3 As shown, the first trigger part 271, the second trigger part 272, and the third trigger part 273 are protruding structures provided on the transmission rod 270, such as...
