Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and in particular to a spring-loaded self-locking mechanism, a wireless charger, and a multi-functional desktop board. Background Technology

[0002] With the rapid development of technology, smart homes and smart furniture are gradually becoming an important part of modern life. Wireless charging technology, due to its convenience and efficiency, is widely used in charging scenarios for electronic devices such as mobile phones and tablets. Currently, many pieces of furniture (such as sofas and desks) have begun to integrate wireless charging functionality to meet users' needs for convenient charging. However, existing furniture with integrated wireless charging still has some problems in practical use. First, the efficiency of wireless charging is closely related to the distance between the charging receiver (such as a mobile phone) and the transmitter. Modern smartphone camera modules typically protrude from the back of the device. When the phone is placed flat on a table, the camera module of some phones can create a gap between the phone and the wireless charging transmitter, thus reducing charging efficiency. Second, the transmitter generates heat during wireless charging. Poor heat dissipation will affect the stability of wireless charging and even shorten the lifespan of the device. Summary of the Invention

[0003] Based on the above, a spring-loaded self-locking mechanism with two heights is provided, along with a wireless charger utilizing this mechanism. This elevates the phone, preventing the camera assembly from interfering with the close proximity of the wireless charging receiving and transmitting coils, thus improving the stability and efficiency of wireless charging. It also allows the wireless charger's heatsink to protrude for heat dissipation. Furthermore, a multi-functional desktop board utilizing this spring-loaded self-locking mechanism or the wireless charger is also provided.

[0004] A spring-loaded self-locking mechanism includes a limiting part, a movable part, and a spring. One end of the spring is fixed vertically to the same environmental system as the limiting part, and the other end is connected to the movable part to apply an upward elastic force to the movable part. The movable part is provided with a sliding rod, and the limiting part is provided with a guide mechanism, a first limiting structure, and a second limiting structure. The guide mechanism is used to force the sliding rod to displace in the left-right direction when the movable part moves vertically. The first limiting structure and the second limiting structure are located at different positions on the sliding rod's movement path, forming a first locking mechanism and a second locking mechanism with the sliding rod and the spring, respectively, to prevent the sliding rod from reaching a set position. When the slide bar reaches the set position, it continues to displace under the action of the spring force, thus preventing the slide bar from moving upward, thereby locking the position of the movable part in the vertical direction under the action of the spring force. The height of the first limiting structure is less than that of the second limiting structure, that is, in the vertical direction, the first limiting structure is located below the second limiting structure. The slide bar cycles between the first limiting structure and the second limiting structure under the action of the guide mechanism and the spring force, so that the movable part can be locked at two different height positions respectively, and the guide mechanism realizes the switching and resetting of the movable part at two different height positions. In this embodiment, "same environmental system" means that the environmental base / mounting seat fixedly connected to one end of the spring and the environmental base / mounting seat fixedly connected to the limiting part are relatively stationary in the vertical direction and will not move relative to each other in the vertical direction. "Same environmental system" can be the same environmental base. For example, the spring and the limiting part are mounted / set on the same substrate or mounting seat. In specific cases, "same environmental system" is usually a shell. The guiding mechanism is used to move the slide bar along a set path. For example, the guiding mechanism may include a slide rail that is inclined as a whole, which can convert the force (resultant force) on the movable part in the vertical direction into a force applied to the slide bar in the left and right direction. Thus, when the movable part is displaced in the vertical direction, the slide bar is forced to be displaced in the left and right direction, thereby realizing the movement of the slide bar along the path set by the guiding mechanism. In addition, the term "spring" in this application refers to any elastic component or elastic mechanism that can generate elastic force. For example, the spring includes mechanical elastic components or mechanisms, or magnetic elastic mechanisms. For example, the spring includes a first magnet and a second magnet. The first magnet is fixed to the limiting part in the same environmental system, and the second magnet is connected to the movable part. The first magnet and the second magnet are opposite each other with the same polarity in the vertical direction to generate a repulsive force, thereby applying an upward elastic force to the movable part.

[0005] In one embodiment, the active part is used to mount a wireless charger transmitter.

[0006] In one embodiment, the guiding mechanism includes a first guide slide for sliding the slide rod from the second limiting structure to the first limiting structure, and a second guide slide for sliding the slide rod from the first limiting structure to the second limiting structure. The first guide slide and the second guide slide are connected end to end to form a closed loop slide, so that the slide rod can cyclically switch positions between the first limiting structure and the second limiting structure via the first guide slide and the second guide slide. The first guide slide includes a first guide slide rail that is generally lower on the left and higher on the right and is arranged upwards, and a second guide slide rail that is generally higher on the left and lower on the right and is arranged downwards. The first guide slide rail is used to receive the slide rod that moves from top to bottom when the movable part moves downwards, and guides the slide rod to move to the left into the projection range of the second guide slide rail in the vertical direction. Under the elastic force of the spring from bottom to top, the slide rod continues to move to the left along the second guide slide rail to the first limiting structure, and under the elastic force of the spring, it presses against the first limiting structure to complete the locking, so that the slide rod, spring and first limiting structure constitute a first self-locking mechanism. The second guide slide includes a third guide slide rail that is generally lower on the left and higher on the right and faces upwards, and a fourth guide slide rail that is generally lower on the left and higher on the right and faces downwards. The third guide slide rail is used to receive the slide rod that moves downwards from the first limiting structure when the movable part moves downwards, and guides the slide rod to move to the left. The fourth guide slide rail is located above the third guide slide rail. Under the action of the spring force, the slide rod moves to the right along the fourth guide slide rail to the second limiting structure and presses against the second limiting structure, completing the locking and the reset after the slide rod completes one cycle, so that the slide rod, spring and second limiting structure constitute the second self-locking mechanism. In this embodiment, the first guide rail is entirely upward-facing to receive the sliding rod moving downwards, and the second guide rail is entirely downward-facing to receive the sliding rod moving upwards under the action of a spring. The first guide rail guides the sliding rod to the area below the second guide rail, that is, within the vertical projection range of the second guide rail, so that the second guide rail can receive the sliding rod moving upwards away from the first guide rail. For example, in a specific structure, the left end of the first guide rail is located below the right end of the second guide rail. The third guide rail is entirely upward-facing to receive the sliding rod moving downwards away from the first limiting structure, and guides the sliding rod to move to the left to leave the vertical projection area of ​​the first limiting structure and enter the vertical projection range of the left end of the fourth guide rail, so that the sliding rod can be received by the fourth guide rail when it moves upwards, and guides the sliding rod to slide from the left end to the right end to the second limiting structure.Furthermore, this embodiment also shows that the first limiting structure is disposed at the left end of the second guide slide rail and located on the movement path of the slide rod; the second limiting structure is disposed at the right end of the fourth guide slide rail and located on the movement path of the slide rod; the position of the second limiting structure is higher than the first guide slide rail, and may be disposed above the first guide slide rail. The first guide slide rail is lower than the second guide slide rail in the vertical direction, the third guide slide rail is located to the left of the first guide slide rail, and its position in the vertical direction is lower than the second guide slide rail; the right end of the fourth guide slide rail is higher than the second guide slide rail. The first limiting structure is disposed at the left end of the second guide slide rail, and the second limiting structure is disposed at the right end of the fourth guide slide rail.

[0007] In one embodiment, the first guide slide further includes a fifth guide slide rail that is generally higher on the left and lower on the right, facing upwards. This fifth guide slide rail receives the sliding rod moving downwards from the second limiting structure and guides the sliding rod to the right within the vertical projection range of the first guide slide rail, allowing the first guide slide rail to receive the sliding rod sliding out from the fifth guide slide rail. In this embodiment, the fifth guide slide rail is located below the second limiting structure, with its right end positioned above the left end of the first guide slide rail and falling within the vertical projection range of the first guide slide rail. This arrangement reduces the length of the fourth guide slide rail, thereby reducing the volume of the limiting portion or its frontal projection area. Simultaneously, it further increases the inclination of the fourth guide slide rail, reducing the contact angle between the sliding rod and the fourth guide slide rail. This increases the rightward thrust of the fourth guide slide rail on the sliding rod when subjected to the same upward thrust, making the sliding of the sliding rod on the fourth guide slide rail smoother and less prone to jamming under friction.

[0008] In one embodiment, a third limiting structure is provided at the left end of the first guide rail to prevent the slide rod from moving to the left and downward, thus limiting the range of movement of the slide rod on the first guide rail; a fourth limiting structure is provided at the left end of the third guide rail to prevent the slide rod from moving to the left and downward, thus limiting the range of movement of the slide rod on the third guide rail. In this embodiment, the third or fourth limiting structure can limit the lowest position of the movable part in the vertical direction, while the second limiting structure can limit the highest position of the movable part in the vertical direction, thereby limiting the range of vertical movement of the movable part.

[0009] In one embodiment, the first guide rail and the second guide rail have a smooth transition to allow the slide rod to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the first guide rail and the second guide rail.

[0010] In one embodiment, the second guide rail or the first limiting structure has a smooth transition with the third guide rail to allow the slide rod to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the second guide rail or the first limiting structure and the third guide rail.

[0011] In one embodiment, the third guide rail and the fourth guide rail have a smooth transition to allow the slide rod to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the third guide rail and the fourth guide rail.

[0012] In one embodiment, the fourth guide rail or the second limiting structure has a smooth transition with the first guide rail, so that the slide rod slides smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the fourth guide rail or the second limiting structure and the first guide rail.

[0013] In one embodiment, the fifth guide rail has a smooth transition with the first guide rail to allow the slide rod to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the fifth guide rail and the first guide rail.

[0014] In one embodiment, the fifth guide rail and the environmental system (base) form a sliding channel for the slide rod.

[0015] In one embodiment, the fourth guide rail and the environmental system (base) are integrated as a whole.

[0016] In one embodiment, the limiting part is integrally formed with the environmental system (base).

[0017] In one embodiment, the environmental system is a shell.

[0018] In one embodiment, the movable part includes a base and a cap connected vertically. The cap is rotatably connected to the base in the circumferential direction, meaning the cap and base are rigidly connected in the vertical direction with no relative movement, but can rotate relative to each other around a coaxial axis in the circumferential direction. The rotational surface of the cap and the base in the circumferential direction is circular. The slide rod is fixedly connected to the base. The side of the cap is provided with a groove, slide rail, or boss in the vertical direction for sliding connection with the environmental system in the vertical direction and for restricting the rotation of the cap in the circumferential direction. Alternatively, the slide rod and the movable part are slidably connected in the circumferential direction and rigidly connected in the vertical direction. That is, there is no relative movement between the slide rod and the movable part in the vertical direction. The side of the movable part is provided with a groove, slide rail, or boss for sliding connection with the environmental system in the vertical direction and for restricting the rotation of the movable part in the circumferential direction. In this embodiment, the circumferential direction of the slide rod and the movable part is relative to the radial and vertical directions, referring to the direction on the side wall of the movable part in the horizontal plane. For example, when the outer wall of the movable part is cylindrical, the circumferential direction is the circumferential direction of the movable part. When the shape of the outer wall of the movable part is polymorphic, the axial direction is the direction parallel to the plane of the outer wall of the movable part and the horizontal plane.

[0019] In one embodiment, the cap and the base enclose a cavity structure for mounting a wireless charger.

[0022] The aforementioned spring-loaded self-locking mechanism, through the spring and the user pressing the movable part, causes the movable part to move downward and upward in the vertical direction. Through the cooperation of the spring, the slide rod, and the limit, the slide rod can be locked at different height positions of the limit part, thereby enabling the movable part to be locked at two different height positions and to cycle between two different high-speed positions.

[0029] In one embodiment, the two ends of the elongated slot limit the slide rod's first range of movement in the circumferential direction, and the distance between the bottom of the elongated slot and the lower edge of the cap limits the slide rod's range of movement in the vertical direction. Furthermore, the limiting portion limits the slide rod's second range of movement in the circumferential direction, and the first range of movement is greater than the second range of movement.

[0032] In one embodiment, the movable part includes a base and a cap connected vertically, the cap and the base forming a cavity structure for mounting a wireless charger; the bottom edge of the cap is provided with the flange.

[0033] In one embodiment, when the flange abuts against the housing, the slide bar abuts against the second limiting structure.

[0034] In one embodiment, when the flange abuts against the housing, the slide bar is located below the second limiting structure.

[0035] In one embodiment, when the slide bar abuts against the second limiting structure, the flange is located below the mounting hole and the distance between it and the housing is greater than or equal to 0.

[0036] In one embodiment, one side of the movable part and the housing are provided with a groove, and the other side is provided with a slide rail or boss that is embedded in the groove to form a sliding connection; the groove is perpendicular to the mounting hole, that is, when the movable part is pressed down, the groove is vertical. The slide rod is slidably connected to the movable part in the circumferential direction and rigidly connected in the vertical direction, that is, there is no relative movement between the slide rod and the movable part in the vertical direction.

[0040] In one embodiment, the limiting part includes a vertically arranged first mounting plate and a second mounting plate. The first mounting plate has a central guide limiting member on its side, and the second mounting plate has a limiting hole. The first and second mounting plates are arranged side by side, with the first mounting plate positioned behind the second mounting plate. The central guide limiting member faces the limiting hole and is located within the projection range of the limiting hole. The gap between the outer wall of the central guide limiting member and the inner wall of the limiting hole forms a channel for the sliding rod to move within the limiting part. In this embodiment, the sliding rod passes through the limiting hole and reaches the first mounting plate, sliding and / or locking against the central guide limiting member during movement. The distance between the outer wall of the central guide limiting member and the inner wall of the limiting hole forms the gap between the outer wall of the central guide limiting member and the inner wall of the limiting hole.

One end of the spring 300 is fixed to the limiting part 100 in the same environmental system in the vertical direction, and the other end is connected to the movable part 200 to apply an upward elastic force to the movable part 200. The movable part 200 is provided with a sliding rod 210, and the limiting part 100 is provided with a guide mechanism, a first limiting structure 122, and a second limiting structure 116. The guide mechanism is used to force the sliding rod 210 to move in the left and right directions when the movable part 200 moves in the vertical direction. The first limiting structure 122 and the second limiting structure 116 are positioned at different locations along the movement path of the slide rod 210. Together with the slide rod 210 and the spring 300, they form the first locking mechanism and the second locking mechanism, respectively. When the slide rod 210 reaches a set position, it is prevented from continuing to move under the force of the spring 300, i.e., the slide rod 210 is prevented from moving upwards. This locks the vertical position of the movable part 200 under the force of the spring 300. The height of the first limiting structure 122 is less than that of the second limiting structure 116; that is, vertically, the first limiting structure 122 is located below the second limiting structure 116. The slide rod 210 cycles between the first limiting structure 122 and the second limiting structure 116 under the action of the guide mechanism and the spring 300, allowing the movable part 200 to be locked at two different heights. The guide mechanism facilitates the switching and resetting of the movable part 200 between these two different heights. In this embodiment, "same environmental system" means that the environmental substrate / mounting seat fixedly connected to one end of the spring 300 and the environmental substrate / mounting seat fixedly connected to the limiting part 100 are relatively stationary in the vertical direction and will not move relative to each other in the vertical direction. Furthermore, "same environmental system" can refer to the same environmental substrate; for example, the spring 300 and the limiting part 100 are mounted / set on the same substrate or mounting seat. In specific cases, "same environmental system" is typically the housing 400. The guide mechanism is used to move the slide bar 210 along a set path. For example, the guide mechanism may include a slide rail 413 that is generally inclined, capable of converting the force (resultant force) on the movable part 200 in the vertical direction into a force applied to the slide bar 210 in the left-right direction. Therefore, when the movable part 200 displaces in the vertical direction, it forces the slide bar 210 to displace in the left-right direction, thereby enabling the slide bar 210 to move along the path set by the guide mechanism. In addition, in this application, "spring 300" generally refers to any elastic component or elastic mechanism capable of generating elastic force. For example, the spring 300 includes mechanical elastic components or mechanisms, or magnetic elastic mechanisms. For example, the spring 300 includes a first magnet and a second magnet. The first magnet and the limiting part are fixed in the same environmental system, and the second magnet is connected to the movable part 200. The first magnet and the second magnet are opposite each other with the same polarity in the vertical direction to generate a repulsive force, thereby applying an upward elastic force to the movable part 200.

[0060] In one embodiment, such as Figure 8 As shown, the active part 200 is used to install the wireless charger transmitter.

[0061] In one embodiment, such as Figure 1As shown, the guiding mechanism includes a first guide slide for sliding the slide rod 210 from the second limiting structure 116 to the first limiting structure 122, and a second guide slide for sliding the slide rod 210 from the first limiting structure 122 to the second limiting structure 116. The first guide slide and the second guide slide are connected end to end to form a closed loop slide, so that the slide rod 210 can cycle through the first guide slide and the second guide slide to switch positions in the first limiting structure 122 and the second limiting structure 116. The first guide slide includes a first guide slide rail 111 with an overall left-lower and right-higher orientation and an upward orientation, and a second guide slide rail 121 with an overall left-higher and right-lower orientation and a downward orientation. The first guide slide rail 111 is used to receive the slide rod 210 moving from top to bottom when the movable part 200 moves downward, and guides the slide rod 210 to move to the left into the projection range of the second guide slide rail 121 in the vertical direction. Under the elastic force of the spring 300 from bottom to top, the slide rod 210 continues to move to the left along the second guide slide rail 121 to the first limiting structure 122, and under the elastic force of the spring 300, it presses against the first limiting structure 122 to complete the locking. Thus, the slide rod 210, the spring 300, and the first limiting structure 122 constitute the first self-locking mechanism. The second guide slide includes a third guide slide rail 112, which is generally lower on the left and higher on the right and is positioned upwards, and a fourth guide slide rail 113, which is generally lower on the left and higher on the right and is positioned downwards. The third guide slide rail 112 is used to receive the slide rod 210 moving downwards from the first limiting structure 122 when the movable part 200 moves downwards, and guides the slide rod 210 to move to the left. The fourth guide slide rail 113 is located above the third guide slide rail 112. Under the elastic force of the spring 300, the slide rod 210 moves to the right along the fourth guide slide rail 113 to the second limiting structure 116 and presses against the second limiting structure 116, thus completing the locking and the reset of the slide rod 210 after one cycle. The slide rod 210, the spring 300, and the second limiting structure 116 constitute the second self-locking mechanism. In this embodiment, the first guide rail 111 is arranged facing upward to receive the slide rod 210 moving from top to bottom, and the second guide rail 121 is arranged facing downward to receive the slide rod 210 moving from bottom to top under the elastic force of the spring 300. The first guide rail 111 guides the slide rod 210 to the area below the second guide rail 121, that is, within the vertical projection range of the second guide rail 121, so that the second guide rail 121 can receive the slide rod 210 moving from bottom to top away from the first guide rail 111. For example, in a specific structure, the left end of the first guide rail is located below the right end of the second guide rail.The third guide rail 112 is positioned upwards to receive the slide rod 210 as it moves downwards away from the first limiting structure 122. It guides the slide rod 210 to move leftwards, exiting the vertical projection area of ​​the first limiting structure 122 and entering the vertical projection range of the left end of the fourth guide rail 113. This ensures that the slide rod 210 is received by the fourth guide rail 113 as it moves upwards, and guides it to slide from the left end to the right end to the second limiting structure 116. Furthermore, this embodiment also shows that the first limiting structure 122 is located at the left end of the second guide rail 121 and on the movement path of the slide rod 210. The second limiting structure 116 is located at the right end of the fourth guide rail 113 and on the movement path of the slide rod 210. The second limiting structure 116 is positioned higher than the first guide rail 111, and may be located above the first guide rail 111. The first guide rail 111 is vertically lower than the second guide rail 121. The third guide rail 112 is located to the left of the first guide rail 111, and its vertical position is also lower than the second guide rail 121. The right end of the fourth guide rail 113 is higher than the second guide rail 121. The first limiting structure 122 is located at the left end of the second guide rail 121, and the second limiting structure 116 is located at the right end of the fourth guide rail 113.

[0062] In one embodiment, such as Figure 1 As shown, the first guide slide rail also includes a fifth guide slide rail 123, which is generally higher on the left and lower on the right and faces upwards. This fifth guide rail 123 receives the slide rod 210 moving downwards from the second limiting structure 116 and guides the slide rod 210 to move to the right within the vertical projection range of the first guide slide rail 111, so that the first guide slide rail 111 can receive the slide rod 210 sliding out from the fifth guide slide rail 123. In this embodiment, the fifth guide slide rail 123 is located below the second limiting structure 116, with its right end positioned above the left end of the first guide slide rail 111 and falling within the vertical projection range of the first guide slide rail 111. This configuration reduces the length of the fourth guide rail 113, thereby reducing the volume of the limiting part 100 or its front projection area. It also increases the inclination of the fourth guide rail 113, reducing the contact angle between the slide rod 210 and the fourth guide rail 113. Consequently, when the slide rod 210 is subjected to the same upward thrust, the rightward thrust of the fourth guide rail 113 on the slide rod 210 is increased, making the sliding of the slide rod 210 on the fourth guide rail 113 smoother and less prone to jamming under the action of friction.

[0063] In one embodiment, such as Figure 1As shown, a third limiting structure 114 is provided at the left end of the first guide rail 111 to prevent the slide rod 210 from moving to the left and downward, thus limiting the range of movement of the slide rod 210 on the first guide rail 111. A fourth limiting structure 115 is provided at the left end of the third guide rail 112 to prevent the slide rod 210 from moving to the left and downward, thus limiting the range of movement of the slide rod 210 on the third guide rail 112. In this embodiment, the third limiting structure 114 or the fourth limiting structure 115 can limit the lowest position of the movable part 200 in the vertical direction, while the second limiting structure 116 can limit the highest position of the movable part 200 in the vertical direction, thereby limiting the range of vertical movement of the movable part 200.

[0064] In one embodiment, such as Figure 6 Figure 7 As shown, the first guide rail 111 and the second guide rail 121 have a smooth transition to allow the slide rod 210 to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the first guide rail 111 and the second guide rail 121.

[0065] In one embodiment, such as Figure 6 Figure 7 As shown, the second guide rail 121 or the first limiting structure 122 and the third guide rail 112 have a smooth transition so that the slide rod 210 can slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the second guide rail 121 or the first limiting structure 122 and the third guide rail 112.

[0066] In one embodiment, such as Figure 6 Figure 7 As shown, the third guide rail 112 and the fourth guide rail 113 have a smooth transition to allow the slide rod 210 to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the third guide rail 112 and the fourth guide rail 113.

[0067] In one embodiment, such as Figure 6 Figure 7 As shown, the fourth guide rail 113 or the second limiting structure 116 smoothly transitions with the first guide rail 111, so that the slide rod 210 slides smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the fourth guide rail 113 or the second limiting structure 116 and the first guide rail 111.

[0068] In one embodiment, such as Figure 6 Figure 7As shown, the fifth guide rail 123 and the first guide rail 111 have a smooth transition to allow the slide rod 210 to slide smoothly between the two guide rails. For example, an arc-shaped smooth transition section is provided between the fifth guide rail 123 and the first guide rail 111.

[0069] In one embodiment, such as Figure 6 Figure 7 As shown, the fifth guide rail 123 and the environmental system (base) form a sliding channel for the slide rod 210.

[0070] In one embodiment, such as Figure 3 Figure 5-8 As shown, the fourth guide rail 113 and the environmental system (base) are an integral whole.

[0071] In one embodiment, such as Figure 3 Figure 5-8 As shown, the limiting part 100 is integrally formed with the environmental system (base).

[0072] In one embodiment, such as Figure 3 Figure 5-8 As shown, the environmental system is a shell of 400.

[0073] In one embodiment, such as Figure 3 Figure 8 As shown, the movable part 200 includes a base 220 and a cap 230 connected vertically. The cap 230 is rotatably connected to the base 220 in the circumferential direction (not shown in the figure), that is, the cap 230 and the base 220 are rigidly connected in the vertical direction and have no relative movement, but can rotate relative to each other around the same axis in the circumferential direction. The rotation surface of the cap 230 and the base 220 in the circumferential direction is circular. The slide rod 210 is fixedly connected to the base 220. The side of the cap 230 is provided with a slide groove 223, a slide rail 413 or a boss in the vertical direction for sliding connection with the environmental system in the vertical direction and for restricting the rotation of the cap 230 in the circumferential direction.

[0074] Or, such as Figure 7 Figure 8As shown, the slide rod 210 and the movable part 200 are slidably connected in the circumferential direction and rigidly connected in the vertical direction. That is, there is no relative movement between the slide rod 210 and the movable part 200 in the vertical direction. The side of the movable part 200 is provided with a slide groove 223, a slide rail 413, or a boss for sliding connection with the environmental system in the vertical direction and restricting the rotation of the movable part 200 in the circumferential direction. In this embodiment, the circumferential direction of the slide rod 210 and the movable part 200 is relative to the radial and vertical directions, referring to the direction on the side wall of the movable part 200 in the horizontal plane. For example, when the outer wall of the movable part 200 is cylindrical, the circumferential direction is the circumferential direction of the movable part 200. When the shape of the outer wall of the movable part 200 is polymorphic, the axial direction is the direction parallel to the plane of the outer wall of the movable part 200 and the horizontal plane.

[0075] In one embodiment, such as Figure 8 As shown, the cap 230 and the base 220 form a cavity structure for mounting the wireless charger.

[0076] In one embodiment, such as Figure 8 As shown, the active section 200 has a hollow structure for installing a wireless charger.

[0077] In one embodiment, such as Figure 3 Figure 5-8 As shown, the system also includes a housing 400, with a mounting hole 411 on its upper surface. A limiting part 100 is disposed within the housing 400 and is fixedly connected to or integrally formed with the housing 400. A spring 300 is disposed within the housing 400, with one end fixedly connected to the housing 400. A movable part 200 is disposed within the mounting hole 411 and is slidably connected to or clearance-fitted with the mounting hole 411.

[0078] The aforementioned spring-loaded self-locking mechanism, through the spring 300 and the user pressing the movable part 200, causes the movable part 200 to move vertically in both downward and upward directions. Through the cooperation of the spring 300, the slide rod 210 and the limiter, the slide rod 210 can be locked at different height positions of the limiter part 100, thereby enabling the movable part 200 to be locked at two different height positions and to cycle between the two different high-speed positions.

[0079] Based on the above, this application also provides a wireless charger using the aforementioned spring-loaded self-locking mechanism.

[0080] A wireless charger, such as Figure 2 Figure 8As shown, this includes the spring-loaded self-locking mechanism in any of the above embodiments. A wireless charging transmitter 500 is mounted on the movable part 200. This configuration allows the wireless charging transmitter 500 to have two different height ranges. When the slide bar 210 abuts against the second limiting structure 116, the movable part 200 is raised, which elevates the phone, preventing the camera assembly from interfering with the close proximity of the wireless charging receiving coil and transmitting coil, improving the stability and efficiency of wireless charging, and allowing the heatsink of the wireless charger to protrude for heat dissipation, thus improving heat dissipation efficiency.

[0081] In one embodiment, such as Figure 3 Figure 4 Figure 8 As shown, the movable part 200 is provided with an annular groove 221, and a sliding ring 211 is disposed within the annular groove 221, with the sliding ring 211 slidably connected to the annular groove 221. The slide rod 210 is fixedly connected to the sliding ring 211. The plane of the annular groove 221 is perpendicular to the moving direction of the movable part 200; that is, when the movable part 200 moves (displaces) in the vertical direction, the annular groove 221 is horizontally positioned. In this embodiment, the slide rod 210 is slidably connected to the movable part 200 in the circumferential direction via the sliding ring 211.

[0082] In one embodiment, such as Figure 3 Figure 4 Figure 8 As shown, it includes at least two slide bars 210, and the slide bars 210 are evenly arranged along the circumference of the ring.

[0083] In one embodiment, such as Figure 3 Figure 4 Figure 8 As shown, it includes three slide rods 210, which are evenly arranged along the circumference of the ring. That is, the angle between two adjacent slide rods 210 and the center of rotation is 120°, so that the force on the movable part 200 in the vertical direction is more balanced and the tilting of the movable part 200 in the vertical direction due to manufacturing errors is reduced.

[0084] In one embodiment, such as Figure 3 Figure 5-8 As shown, the movable part 200 includes a base 220 and a cap 230 connected vertically, with the cap 230 and the base 220 forming a cavity structure for mounting the wireless charger. The upper surface of the base 220 has an annular groove 221, and the side has an elongated slot 222 communicating with the annular groove 221. A slip ring 211 is installed in the annular groove 221, and a sliding rod 210 passes through the elongated slot 222 and is inserted into a limiting part 100, slidingly connected to and / or locked with the limiting part 100. In this embodiment, when the slip ring 211 rotates within the annular groove 221, the sliding rod 210 swings within the elongated slot 222.

[0085] In one embodiment, the two ends of the elongated slot 222 limit the first range of movement of the slide rod 210 in the circumferential direction, and the distance between the bottom of the elongated slot 222 and the lower edge of the cap 230 limits the range of movement of the slide rod 210 in the vertical direction. Furthermore, the limiting portion 100 limits a second range of movement of the slide rod 210 in the circumferential direction, and the first range of movement is greater than the second range of movement.

[0086] In one embodiment, such as Figure 3 Figure 8 As shown, the system also includes a housing 400, with a mounting hole 411 on its upper surface. A limiting part 100 is disposed within the housing 400 and is fixedly connected to or integrally formed with the housing 400. A spring 300 is disposed within the housing 400, with one end fixedly connected to the housing 400. A movable part 200 is disposed within the mounting hole 411 and is slidably connected to or clearance-fitted with the mounting hole 411.

[0087] In one embodiment, such as Figure 3 Figure 8 As shown, a flange 231 is also provided on the side of the movable part 200. The position height of the flange 231 is greater than the position height of the slide rod 210. For example, the flange 231 is located above the slide rod 210. The flange 231 serves as a limit to prevent the movable part 200 from sliding out of the mounting hole 411.

[0088] In one embodiment, such as Figure 8 As shown, the movable part 200 includes a base 220 and a cap 230 connected vertically, with the cap 230 and the base 220 forming a cavity structure for mounting a wireless charger. A flange 231 is provided on the bottom edge of the cap 230.

[0089] In one embodiment, when the flange 231 abuts against the housing 400, the slide bar 210 abuts against the second limiting structure 116.

[0090] In one embodiment, when the flange 231 abuts against the housing 400, the slide bar 210 is located below the second limiting structure 116.

[0091] In one embodiment, when the slide bar 210 abuts against the second limiting structure 116, the flange 231 is located below the mounting hole 411 and the distance between it and the housing 400 is greater than or equal to 0.

[0092] In one embodiment, such as Figure 3 Figure 4 Figure 6-8As shown, one side of the movable part 200 and the housing 400 are provided with a sliding groove 223, and the other side is provided with a slide rail 413 or boss that is embedded in the sliding groove 223 to form a sliding connection. The sliding groove 223 is set perpendicular to the mounting hole 411, that is, when the movable part 200 is pressed down, the sliding groove 223 is set vertically. The slide rod 210 is slidably connected to the movable part 200 in the circumferential direction and rigidly connected in the vertical direction, that is, there is no relative movement between the slide rod 210 and the movable part 200 in the vertical direction.

[0093] In one embodiment, such as Figure 3 Figure 5-8 As shown, a sleeve 412 extends downward from the mounting hole 411 and is fitted onto the movable part 200. A groove 223 or a slide rail 413 / protrusion is provided on the inner side wall of the sleeve 412.

[0094] In one embodiment, such as Figure 3-8 As shown, the movable part 200 includes a base 220 and a cap 230 connected vertically, with the cap 230 and the base 220 forming a cavity structure for mounting the wireless charger. The upper surface of the base 220 has an annular groove 221, and the side has an elongated slot 222 communicating with the annular groove 221. A slip ring 211 is installed in the annular groove 221, and a slide rod 210 passes through the elongated slot 222 and is slidably connected to and / or locked by the limiting part 100. The side of the cap 230 and the housing 400 each have a sliding groove 223 on one side and a slide rail 413 or boss embedded in the sliding groove 223 to form a sliding connection.

[0095] In one embodiment, such as Figure 6 Figure 7As shown, the limiting part 100 includes a limiting hole 110 and a central guide limiting member 120, which is disposed inside or behind the limiting hole 110. The inner sidewall of the limiting hole 110 is sequentially provided with a first guide rail 111, a third limiting structure 114, a third guide rail 112, a fourth limiting structure 115, a fourth guide rail 113, and a second limiting structure 116. The outer sidewall of the central guide limiting member 120 is sequentially provided with a fifth guide rail 123, a second guide rail 121, and a first limiting structure 122. Alternatively, the inner sidewall of the limiting hole 110 is sequentially provided with a first guide rail 111, a third limiting structure 114, a third guide rail 112, a fourth guide rail 113, and a second limiting structure 116, and the outer sidewall of the central guide limiting member 120 is sequentially provided with a second guide rail 121 and a first limiting structure 122.

In this embodiment, the first guide rail 111 to the fifth guide rail are the same as the first guide rail 111 to the fifth guide rail in the above embodiment, and the first limiting structure 122 to the fourth limiting structure 115 are the same as the first limiting structure 122 to the fourth limiting structure 115 in the above embodiment.

[0096] In one embodiment, such as Figure 3 Figure 6-8 As shown, the limiting part 100 includes a vertically arranged first mounting plate 421 and a second mounting plate 422. A central guide limiting member 120 is provided on the side of the first mounting plate 421, and a limiting hole 110 is formed in the second mounting plate 422. The first mounting plate 421 and the second mounting plate 422 are arranged side by side, with the first mounting plate 421 located behind the second mounting plate 422. The central guide limiting member 120 faces the limiting hole 110 and is located within the projection range of the limiting hole 110. The gap between the outer wall of the central guide limiting member 120 and the inner wall of the limiting hole 110 forms a channel for the slide rod 210 to move within the limiting part 100. In this embodiment, the slide rod 210 passes through the limiting hole 110 and reaches the first mounting plate 421, and slides and / or locks against the central guide limiting member 120 during movement. The distance between the outer wall of the central guide limiter 120 and the inner wall of the limiting hole 110 forms the gap between the outer wall of the central guide limiter 120 and the inner wall of the limiting hole 110. The central guide limiter 120 is fixedly connected to the first mounting plate 421 or integrally formed therefrom.

[0097] In one embodiment, such as Figure 8 As shown, the first mounting plate 421 and the second mounting plate 422 are fixedly connected to the housing 400 or integrally formed.

[0098] In one embodiment, such as Figure 3 Figure 6-8 As shown, the upper half of the limiting hole 110 is opened on the lower part of the sleeve 412 with the opening facing downward, and the lower half is opened on the upper part of the second mounting plate 422 with the opening facing upward. The limiting hole 110 of this application is formed by the mutual cooperation between the sleeve 412 and the second mounting plate 422.

[0099] In one embodiment, the end of the slide bar 210 is provided with a pulley (not shown in the figure) to reduce friction with the guide rail.

[0100] In one embodiment, the first limiting structure 122 to the fourth limiting structure 115 is one of the limiting surface, the limiting post, the limiting plate, and the limiting groove.

[0101] In one embodiment, such as Figure 8 As shown, the housing 400 includes an upper housing 410 and a lower housing 420 connected vertically. The first mounting plate 421 is fixedly connected to the lower housing 420 or integrally formed. The second mounting plate 422 consists of an upper mounting plate (not shown in the figure; in another embodiment, the upper mounting plate and the sleeve 412 are integrally formed) and a lower mounting plate. The upper mounting plate is fixedly connected to the upper housing 410 or integrally formed, and the lower mounting plate is fixedly connected to the lower housing 420 or integrally formed. A portion of the limiting hole 110 is provided on the upper mounting plate, and a portion is provided on the lower mounting plate.

The fourth guide rail 113 and the second limiting structure 116 are mounted on the upper mounting plate.

[0103] In one embodiment, such as Figure 3 Figure 8 As shown, the upper housing 410 is provided with a semi-blind hole 415, which is used to install a second wireless charging transmitter 600 for wirelessly charging the watch. The second wireless charging transmitter 600 is rotatably connected to the upper housing 410.

[0104] In one embodiment, such as Figure 3 Figure 8 As shown, the housing of the second wireless charging transmitter 600 is provided with a finger-pull groove 414 for easy finger removal. The semi-blind hole 415 is located on the upper surface of the upper housing 410 and has a cut at its edge. The position of the cut corresponds to the position of the finger-pull groove 414, so as to facilitate the use of fingertips to pull the wireless charging transmitter 500 in the second wireless charging transmitter module out of the semi-blind hole 415.

[0105] In one embodiment, such as Figure 8 As shown, a wire-passing groove 416 is formed on the side wall of the semi-blind hole 415. A first pivot mounting seat is provided on the back of the upper housing 410. The second wireless charging transmitter 600 includes a second pivot mounting seat and an L-shaped connecting rod. The first pivot mounting seat and the second pivot mounting seat are assembled together to form a pivot mounting seat. One end of the L-shaped connecting rod is rotatably connected to the pivot mounting seat, and the other end passes through the wire-passing groove 416 and is fixedly connected to the outer shell of the second wireless charging transmitter 600.

[0106] In one embodiment, such as Figure 3 Figure 8 As shown, it also includes a USB charging module 700 for connecting an external charging cable to charge electronic devices via wired connection. A hole is provided on the upper housing 410 at a corresponding position for the USB charging module 700 to allow the power cable to pass through.

[0107] In one embodiment, such as Figure 3 Figure 8 As shown, the hole above the USB charging module 700 is equipped with a sliding door.

[0108] In one embodiment, such as Figure 4 Figure 8 As shown, it also includes a hook lock post 820 and a push-button latch 810. The push-button latch 810 is fixedly connected to the housing 400, and the hook lock post 820 is fixedly connected to the movable part 200. The push-button latch 810 can lock and release the hook lock post 820 by pressing, forming a push-button self-locking mechanism together with the spring 300. With this configuration, this application uses the same spring 300 to form two self-locking mechanisms, and the two self-locking mechanisms cooperate with each other, making the spring-loaded self-locking process smoother and the locking position of the movable part more precise. At the same time, the self-locking mechanism produces a "click" sound during locking or unlocking, improving the user experience. In addition, the self-locking mechanism composed of the hook lock post 820, the push-button latch 810, and the spring 300 also constitutes the central guide mechanism of the movable part in this application, serving as a central guide mechanism for the vertical movement of the movable part.

[0109] In one embodiment, such as Figure 4 Figure 6 Figure 8 As shown, the lower housing 420 is also provided with a first mounting plate 423, a second mounting plate 424, and an anti-slip rib 425. The first mounting plate 423 and the second mounting plate 424 are respectively disposed at both ends of the lower housing 420, and are used to fix the lower housing 420 to the desktop. The anti-slip rib 425 is disposed on the outer side of the lower housing 420 and is horizontally disposed.

[0110] In one embodiment, a limiting plate is also provided at the edge of the lower housing 420. The limiting plate serves to position and limit the lower housing 420 when it is installed on the tabletop.

[0111] The wireless charger provided above enables the wireless charging transmitter 500 to have two different height ranges. When the slider 210 abuts against the second limiting structure 116, the movable part 200 is raised, which can raise the mobile phone and prevent the camera component from affecting the wireless charging receiving coil and transmitting coil from getting too close to each other, thereby improving the stability and efficiency of wireless charging. It can also make the heat sink of the wireless charger protrude to dissipate heat, thereby improving heat dissipation efficiency.

[0112] Based on the above, this application also provides a multi-functional desktop board.

[0113] A multi-functional desktop board includes either the spring-loaded self-locking mechanism of any of the above-mentioned components, or the wireless charger of any of the above-mentioned components. This configuration allows the wireless charging transmitter 500 to have two different height ranges. When the slide bar 210 abuts against the second limiting structure 116, the movable part 200 is raised, elevating the mobile phone a certain distance away from the desktop board. This prevents the mobile phone camera or other parts higher than the wireless charging receiver from interfering with the wireless charging receiving coil's proximity to the wireless charging transmitter 500 located within the desktop board, improving charging and heat dissipation efficiency, while also preventing liquids such as water on the surface of the desktop board from affecting wireless charging.

[0114] In one embodiment, the multifunctional desktop panel includes any one of an office desk panel, a dining table panel, an armrest box panel, a coffee table panel, or a stove panel.

[0115] The aforementioned multi-functional desktop board allows the wireless charging transmitter 500 to have two different height ranges. When the slide bar 210 abuts against the second limiting structure 116, the movable part 200 is raised, which can raise the mobile phone a certain distance away from the desktop board. This can prevent the mobile phone camera or other parts higher than the wireless charging receiving device from affecting the wireless charging receiving coil and keeping it close to the wireless charging transmitter 500 set in the desktop board, thereby improving charging efficiency and heat dissipation efficiency. At the same time, it can prevent water or other liquids on the surface of the desktop board from affecting wireless charging.

[0116] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
