Description

Technical Field

[0001] This invention relates to the field of wireless charging technology, specifically a slider-type long-life wireless charging dual-mode switching charger. Background Technology

[0002] In wireless charging, different mobile phones often require different wireless charging structures. For example, common charging coils in current wireless charging protocols include magnetic charging coils and non-magnetic charging coils, designed for phones using different charging protocols. Sometimes, different charging structures need to be used in the same charging location, such as in compact spaces where different users frequently need to work together, like in car wireless chargers or other confined wireless charging scenarios. If different charging coils need to be used to charge different phones in the same location, they need to be assembled in a replaceable manner. Switching between these coils requires a dedicated drive structure. During this process, friction occurs as the assembly structures of the different charging modules move relative to each other. In ordinary track structures, the force is often concentrated on the entire surface during relative movement, resulting in high friction and wear. This significantly reduces the device's lifespan and also increases noise, often failing to meet quiet operation requirements. For instance, when a wireless charging structure is used inside a car, the sound of switching between the two charging modules can easily disrupt the car's quietness.

[0003] To facilitate portability, placement, and assembly, wireless charging devices need to be designed to be more compact and robust. This has always been a pursuit in the development of wireless charging technology, especially when wireless chargers are mounted as accessories on other mobile devices, such as in-vehicle wireless charging systems. The space requirements for assembly are even more stringent; the smaller the overall size of the wireless charger, the greater its compatibility with other products. Furthermore, when wireless charging devices contain complex transmission structures, a more robust assembly structure needs to be designed within a compact framework to extend the device's lifespan. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, the present invention provides a sliding rod type long life wireless charging dual-mode switching charger with more reasonable force distribution, less wear and noise when switching charging coil modules.

[0005] (II) Technical Solution: To achieve the above objectives, the present invention provides the following technical solution: This sliding rod type high-life wireless charging dual-mode switching charger includes an assembly plate, on which a lifting coil and a sliding coil are mounted. The lifting coil moves vertically up and down relative to the assembly plate, and the sliding coil moves horizontally back and forth relative to the assembly plate. The upper part of the assembly plate is provided with a charging position corresponding to the wireless charging device. The lifting coil and the sliding coil can move to the charging position respectively through linkage and enter the charging state to charge the wireless device on the upper part. The assembly plate is equipped with transverse sliding rods on both sides, the sliding coil is mounted on the sliding bracket, and the sliding bracket is provided with transverse sliding grooves corresponding to the sliding rods on both sides respectively.

[0006] Preferably, the lifting coil is a magnetic coil, and the sliding coil is a non-magnetic charging coil. The magnetic coil needs to be closer to the receiving coil of the device being charged compared to the non-magnetic coil.

[0007] Preferably, the slide rod has a circular cross-section, and the transverse slide groove is provided with evenly distributed strip-shaped protrusions; after the slide rod is assembled, the protruding ends of the strip-shaped protrusions are attached to the surface of the slide rod.

[0008] Preferably, the assembly plate is rectangular, with vertically oriented assembly posts at its four corners. The slide rod is mounted on the assembly posts on both sides. The two assembly posts on the rear side of the assembly plate have horizontal insertion holes, and the two assembly posts on the front side of the assembly plate have rearward and upward-opening embedding grooves. The tail of the slide rod is inserted into the insertion hole of the rear assembly post, and the front of the slide rod is embedded in the embedding groove of the front assembly post.

[0009] Preferably, the outer side of the transverse slide groove has an open structure, and the inner side of the transverse slide groove has a straight tooth section parallel to the slide rod.

[0010] Preferably, the sliding bracket, transverse groove, and straight tooth section are integrally injection molded from plastic or rubber, while the sliding rod is made of metal. Using different materials for the two relatively sliding parts results in lower friction and noise.

[0011] Preferably, the spur gear segment is driven to slide laterally by a conventional module, which includes a gear set, a worm gear, and a drive motor. The spur gear segment is driven by the gear set meshing with the worm gear, and the worm gear is mounted on the drive motor.

[0012] Preferably, the gear set includes two vertically coaxially machined upper gears and a lower worm gear. The upper gear meshes with a spur gear section, and the lower worm gear meshes with the worm. The gear set is rotatably assembled with a transition shaft through an axial through hole. The transition shaft is assembled with a drive motor on a transmission bracket. The transmission bracket is fixedly connected to an assembly plate.

[0013] Preferably, the upper gear and lower worm gear of the gear set are integrally injection molded from plastic or rubber materials, and the worm is made of metal materials.

[0014] Preferably, a circuit board is mounted on the lower part of the assembly plate, and a wire hole is machined in the middle of the assembly plate to facilitate the connection of the upper lifting coil, sliding coil, and transmission module circuits to the lower circuit board through the wire hole.

[0015] Preferably, the assembly plate is externally fixedly fitted with an upper shell and a lower shell, which are fastened together as a single unit.

[0016] Preferably, the assembly plate has two or more vertical limiting units integrally machined, the lifting coil is assembled on the lifting bracket, and the limiting units on the assembly plate are designed at the positions corresponding to the outer edges of the lifting coil; the limiting unit includes a vertical slide rail that runs vertically through the assembly plate, and the lifting bracket is provided with a vertical slide bar corresponding to the vertical slide rail.

[0017] Preferably, each vertical slide rail includes two adjacent vertical sliding pieces, the adjacent edges of the two vertical sliding pieces forming a vertical slide rail gap. The vertical slide bar adopts a slat structure, and the two sides of the vertical slide bar are vertically slidably assembled with the slide rail gap of the two vertical sliding pieces. The two adjacent vertical sliding pieces limit the two sides of the slide bar, which can prevent the lifting bracket from deflecting within the vertical slide rail.

[0018] Preferably, the two vertical sliding pieces of the vertical slide are connected by a vertical inner connecting rib, the cross-section of which is C-shaped; this greatly enhances the firmness of the two vertical sliding pieces on the vertical slide relative to the assembly plate.

[0019] Preferably, the mounting plate is provided with limiting units on both sides corresponding to the mounting positions on both sides of the lifting bracket, and the lifting bracket is provided with vertical outer connecting ribs surrounding the limiting units on both sides, and the cross section of the outer connecting ribs is also C-shaped; the sliding bracket is provided with linkage rails on both sides, and the outer connecting ribs on both sides of the lifting bracket are provided with shafts that are slidably assembled with the linkage rails. During the lateral sliding of the sliding bracket, the lifting bracket is driven to move up and down through the linkage rails and shafts.

[0020] Preferably, the sliding bracket has vertical sliding edges integrally machined on both sides, and the inner sides of the two sliding edges are respectively provided with the linkage rails, and the linkage rails are provided with inclined sections; when the sliding bracket moves laterally, the shaft moves relative to the inclined section of the linkage rail to generate vertical linkage.

[0021] When the sliding bracket moves laterally, the linkage track moves accordingly. Since the lifting bracket can only slide vertically after being limited by the limiting unit, the design of the inclined section on the linkage track makes the lifting bracket only able to move vertically.

[0022] Preferably, the lifting bracket is mounted on the upper part of the mounting plate, and the mounting plate has recessed grooves on both sides opposite the vertical outward connecting ribs, with the limiting unit mounted in the recessed grooves. Because the linkage rails on both sides of the sliding bracket are designed to be in a lower position, the recessed groove design makes the overall size of the equipment thinner.

[0023] Preferably, the vertical slide bar and the outer connecting rib extend downwards, and the recessed groove has an inner opening and an outer groove that penetrate the assembly plate at positions corresponding to the vertical slide bar and the outer connecting rib. The inner opening and outer groove facilitate the lower ends of the vertical slide bar and the outer connecting rib to extend to the lower part of the assembly plate, which greatly increases the assembly space of each transmission structure and helps to further design the overall size of the equipment to be thinner.

[0024] (III) Beneficial Effects: Compared with the prior art, the present invention provides a slider-type long-life wireless charging dual-mode switching charger, which has the following beneficial effects: 1. This sliding rod type high-life wireless charging dual-mode switching charger uses a sliding rod and a horizontal sliding groove design to facilitate the lateral movement of the sliding bracket relative to the mounting plate. The use of the sliding rod as a track not only allows for a more spacious size design for the relatively sliding part and a more robust design structure, but also the separate design of the sliding rod and the mounting plate facilitates more precise processing of the sliding surface of the sliding rod, greatly reducing sliding friction and noise, and improving product life.

[0025] Furthermore, the circular cross-section design of the slide rod and the strip-shaped protrusion design in the transverse slide groove ensure that after the transverse slide groove and the slide rod are assembled, the protruding end of the strip-shaped protrusion is attached to the surface of the slide rod. This makes the contact between the transverse slide groove and the slide rod assembly a line contact, which, compared to a surface contact structure, results in fewer contact points during movement, less friction, and smoother operation.

[0026] Furthermore, the separate design of the slide rod and the mounting plate allows the slide rod to be made of metal, which reduces friction when the slide rod and the sliding bracket are assembled in a single transverse groove made of plastic.

[0027] Furthermore, the open structure design of the transverse slide groove ensures that only one side of the slide rod and the transverse slide groove bears force. This means that even if the slide rod or the transverse slide groove experiences slight deformation, or if the dimensions between their contact surfaces are not precise enough, the contact force can be transmitted to the open side, allowing for smooth sliding movement of the slide rod and the transverse slide groove. This significantly reduces the frictional force during sliding, thus lowering frictional noise. Using this structure requires lower precision in the machining and assembly of parts, reducing the adaptation requirements for product processing and assembly. Furthermore, even with slight collisions and deformations during use, the smooth operation of the product can be guaranteed.

[0028] 2. In this sliding rod-type high-lifespan wireless charging dual-mode switching charger, the limiting structure of the lifting bracket is designed around the lifting coil, resulting in more dispersed force. Simultaneously, the vertical slider and vertical slide rail provide limiting assembly, making the structure of the lifting bracket individual component more compact. Furthermore, the vertical slider also enhances the strength of the lifting bracket. The limiting unit assembling the vertical slider uses a vertically continuous slide rail structure, allowing the lower end of the vertical slider to slide directly to the lower part of the assembly plate. The arrangement of multiple limiting units around the lifting bracket ensures stability during its vertical movement. This, while maintaining the product's structural strength, also allows for more design space to accommodate other product structures, significantly increasing the product's compactness.

[0029] Furthermore, the vertical slide structure with two closely spaced vertical slide plates creates a line and surface contact with the vertical slide bar. Compared to surface-to-surface contact, this significantly reduces friction during movement. Simultaneously, when the two adjacent edges of the limiting unit slide against the vertical slide bar, if the lifting bracket experiences deflection within the vertical slide track, this deflection force is entirely located at the edge of the vertical slide plate. This effectively prevents the lifting bracket from deflecting within the vertical slide track while maintaining the overall structural compactness.

[0030] Furthermore, the connecting ribs vertically connect the two vertical sliders within the same limiting unit from the side, making the entire limiting unit more robust. At the same time, the C-shaped inner connecting ribs can make way for the outer side of the vertical slider, so that the vertical slider does not interfere with the vertical slider when it slides up and down within it.

[0031] Furthermore, by designing limiting units on both sides of the assembly plate, and employing a vertical external connecting rib structure surrounding the limiting units, and designing the shaft structure on the outer surface of the external connecting ribs, the sliding bracket's linkage rails on both sides can achieve lateral and vertical sliding between themselves and the shaft. This structure, with external connecting ribs surrounding the limiting units, ensures that the limiting force and driving force of the lifting bracket are located close to each other, allowing the two forces to quickly cancel each other out within the lifting bracket. This results in minimal overall stress on the lifting bracket, and because they are in the same position, deformation is less likely to occur, significantly improving the assembly lifespan of the lifting bracket and the assembly plate. Simultaneously, the above structure is very compact, effectively reducing the final size of the charger.

[0032] Furthermore, the vertical sliding plate, inner connecting ribs, and outer connecting ribs of the upper limit unit of the assembly plate are all vertically designed with respect to their main body, which facilitates mold opening during injection molding and can effectively reduce processing difficulty and processing costs.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1 The slider-type high-lifespan wireless charging dual-mode switching charger described in Embodiment 1 of this patent is mainly a vehicle charger, primarily used for wireless charging of mobile phones. Its shape is as follows... Figure 1 As shown, the upper slot is designed to hold a mobile phone to be charged. This dual-mode switching charger has a dual-mode switching function, specifically, it can charge devices (mobile phones in this embodiment) using two different wireless charging specifications separately. Simultaneously, their charging positions are both within the same slot.

[0037] Specifically, the structure of the device is as follows: Figure 2 As shown, the sliding rod-type high-lifespan wireless charging dual-mode switching charger includes an assembly plate 1. The assembly plate 1 is equipped with a lifting coil 2 and a sliding coil 3, both connected to a circuit. These two types of charging coils correspond to two different charging structures. The lifting coil 2 is a magnetic coil, primarily used for charging Apple phones; the sliding coil 3 is a non-magnetic coil, primarily used for wireless charging Android phones.

[0038] In specific design, such as Figure 2 As shown, the lifting coil 2 moves vertically up and down relative to the assembly plate 1, and the sliding coil 3 moves horizontally back and forth relative to the assembly plate 1. The upper part of the assembly plate 1 is provided with a charging position for the corresponding wireless charging device. The lifting coil 2 and the sliding coil 3 are linked and can move to the charging position respectively. Specifically, when the lifting coil 2 moves to the lower position and the sliding coil 3 moves to the middle position above the lifting coil 2, the lifting coil 2 is de-energized and the sliding coil 3 is energized, allowing wireless charging of the Android phone above the device. When the sliding coil 3 moves backward to make way for the middle position, the lifting coil 2 moves upward to the charging position, at which point the sliding coil 3 is de-energized and the lifting coil 2 is energized, allowing wireless charging of the Android phone above the device.

[0039] The lifting coil 2 and the sliding coil 3 can each use independent transmission structures, allowing them to move laterally and vertically respectively, thereby achieving relative position transformation. This will not be described in detail here. In this embodiment, the mounting plate 1 has horizontal sliding rods 11 mounted on both sides, and the sliding coil 3 is mounted on a sliding bracket 31. The sliding bracket 31 has horizontal sliding grooves 311 corresponding to the sliding rods 11 on both sides. When switching between wireless charging modes, the sliding bracket 31 slides laterally along the sliding rods 11 with the sliding coil 3 in its carriage.

[0040] This sliding rod type high-life wireless charging dual-mode switching charger uses a design of sliding rod 11 and horizontal sliding groove 311 to facilitate the horizontal movement of the sliding bracket 31 relative to the mounting plate 1. The use of sliding rod 11 as a track not only allows for a more spacious size design for the relatively sliding part and a more robust design structure, but also the separate design of sliding rod 11 and mounting plate 1 facilitates more precise processing of the sliding surface of sliding rod 11, significantly reducing sliding friction and noise, and improving product life.

[0041] The separate design of the slide rod 11 and the mounting plate 1 makes it convenient to use metal materials to make the slide rod 11. In this way, when the sliding bracket 31 is made of plastic materials, the friction is lower when the slide rod 11 is assembled with the transverse sliding groove 311 of the sliding bracket 31.

[0042] In specific design, such as Figure 2 , Figure 3 and Figure 4 As shown, the slide rod 11 has a circular cross-section, and the transverse slide groove 311 is provided with evenly distributed strip-shaped protrusions 3111; after the slide rod 11 is assembled, the protruding ends of the strip-shaped protrusions 3111 are attached to the surface of the slide rod 11.

[0043] Furthermore, the circular cross-section design of the slide rod 11 and the strip-shaped protrusion 3111 design in the transverse slide groove 311 ensure that after the transverse slide groove 311 is assembled with the slide rod 11, the protruding end of the strip-shaped protrusion 3111 is attached to the surface of the slide rod 11. This makes the contact between the transverse slide groove 311 and the slide rod 11 a line contact, which, compared to a surface contact structure, results in fewer contact points during movement, less friction, and smoother operation.

[0044] like Figure 2 and Figure 8 As shown, the assembly plate 1 is rectangular. In this embodiment, the device is mainly used to charge square mobile phones. It is most suitable to set the overall placement surface of the device to be square. Therefore, when the assembly plate 1 is rectangular, it is most conducive to the centralized design of the device, making the overall size of the device smaller.

[0045] In the specific design, the four corners of the assembly plate 1 are designed with vertically oriented assembly posts 101. The sliding rods 11 are respectively assembled on the two side assembly posts 101. The two rear assembly posts 101 of the assembly plate 1 are designed with horizontal insertion holes, and the two front assembly posts 101 of the assembly plate 1 are designed with rearward and upward opening embedding grooves. During the assembly process, the sliding rods 11 need to be assembled first on the horizontal sliding grooves 31 on both sides of the sliding bracket 31. Then, the tail parts of the two sliding rods 11 are respectively inserted into the insertion holes of the two rear assembly posts 101 of the assembly plate 1. Finally, the front parts of the two sliding rods 11 are embedded into the embedding grooves of the front assembly posts 101. The above assembly structure is simple and easy to implement, facilitating the assembly of the sliding bracket 31 and the sliding rods 11 on the assembly plate 1.

[0046] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the outer side of the transverse slide groove 311 is provided with an open structure, and the inner side of the transverse slide groove 311 is provided with a straight tooth section 312 parallel to the slide rod 11.

[0047] The open structure design of the transverse slide groove 311 ensures that only one side of the slide rod 11 and the transverse slide groove 311 bears force. This allows the contact force to be transmitted to the open side even when the slide rod 11 or the transverse slide groove 311 has slight deformation, or when the dimensions between their contact surfaces are not precise enough, ensuring smooth sliding movement of the slide rod and the transverse slide groove 311. This significantly reduces frictional force and noise during sliding. Using this structure lowers the dimensional accuracy requirements for component processing and assembly, reducing the adaptation requirements for product processing and assembly. Furthermore, even with slight collisions and deformations during use, the smooth operation of the product is guaranteed.

[0048] In the specific design, such as Figure 4 and Figure 5 As shown, the sliding bracket 31, the transverse slide groove 311, and the straight tooth section 312 are integrally injection molded from plastic or rubber materials, while the slide rod 11 is made of metal. In specific implementations, the slide rod 11 can be made of stainless steel. To reduce weight, the slide rod 11 can be further made of stainless steel tubing. When the transverse slide groove 311 of the bracket 31 slides relative to the slide rod 11, the load is extremely low, and the stainless steel tubing is sufficient to bear the force.

[0049] This allows for a lighter overall weight of the equipment, and the use of standard fittings significantly reduces parts processing costs. The stainless steel material makes the slide rod 11 less prone to rusting during use, extending its service life. When the two sliding parts use different materials, especially when the slide rod 11 is made of metal, its surface can be machined more smoothly, resulting in lower friction, less noise, and less wear.

[0050] In this device, such as Figure 2 As shown, the straight tooth segment 312 drives the sliding bracket 31 to slide laterally via the conventional module 4. Figure 6 As shown, the conventional module 4 includes a gear set 41, a worm gear 42, and a drive motor 43. The spur gear segment 312 meshes with the worm gear 42 through the gear set 41, and the worm gear 42 is mounted on the drive motor 43. The meshing transmission of the worm gear 42 can greatly reduce the final output speed of the transmission, making the movement of the sliding bracket 31 more stable and smooth. At the same time, the transmission structure of the spur gear segment 312 facilitates the conversion of rotary motion into linear motion. Compared with structures such as lead screw transmission, the precision requirements are lower during meshing transmission, which can effectively reduce the processing and assembly costs of the transmission structure, and ultimately reduce the operating cost of the equipment.

[0051] like Figure 6As shown, the gear set 41 includes two vertically coaxially machined upper gears 411 and a lower worm gear 412. The upper gears 41 mesh with the spur gear section 312, and the lower worm gear 412 meshes with the worm 42. Integrated machining reduces the number of parts while ensuring the coaxiality of the upper gears 411 and the lower worm gear 412, as well as other dimensions and machining parameters, resulting in higher transmission accuracy. The gear set 41 is rotatably assembled with a transition shaft 413 through an axial through hole. The transition shaft 413 and the drive motor 43 are mounted on a transmission bracket 44, which is fixedly connected to the mounting plate 1. This conventional module 4 is completely integrated through the transmission bracket 44, allowing for independent assembly of the precise transmission assembly parts. This not only effectively ensures assembly accuracy but also allows for quick assembly during final assembly. The integrated conventional module 4 can be directly assembled onto the mounting plate 1 via the transmission bracket 44, significantly improving equipment assembly efficiency and helping to reduce assembly processing costs. In the specific design, one end of the worm gear 42 is assembled with the drive motor 43, and the other end of the worm gear 43 is rotatably assembled with the vertical edge of the transmission bracket 44. When the transmission bracket 44 uses a metal plate structure, the vertical edge of the transmission bracket 44 can be formed by bending; when the transmission bracket 44 uses a plastic part, the vertical edge of the transmission bracket 44 can be integrally injection molded. This structure is simple and easy to implement, and at the same time, this structure allows both ends of the worm gear 42 to be positioned and assembled, resulting in more stable transmission operation compared to a cantilever structure.

[0052] like Figure 7 As shown, a circuit board 5 is mounted on the lower part of the assembly plate 1. A wire-passing hole is machined in the middle of the assembly plate 1 to facilitate the connection of the wiring of the upper lifting coil 2, sliding coil 3, and transmission module 4 to the lower circuit board 5. The assembly plate 1 of this device has functional transmission components mounted on the upper part and a circuit board mounted on the lower part, allowing the main functions and circuits of the entire product to be concentrated on the assembly plate 1. The design of the wire-passing hole in the middle of the assembly plate allows for convenient internal wiring between the lifting coil 2, sliding coil 3, transmission module 4, and circuit board 5, achieving circuit connection while reducing wiring length and making the assembled device wiring more concise.

[0053] like Figure 1As shown, an upper housing 12 and a lower housing 13 are fixedly mounted on the outside of the assembly plate 1, and the upper housing 12 and the lower housing 13 are fastened together as a single unit. The upper housing 12 has a corresponding mobile phone placement slot for placing mobile phones or other devices to be wirelessly charged. In this device, a separate assembly plate 1 is used for the integrated assembly of the main body parts, which helps to standardize the product. The assembly of the entire device is then completed by the fastening of the upper housing 12 and the lower housing 13. This design makes the design of the external adapter housing more convenient and faster, facilitates product modularization, and allows for faster design and implementation of products based on the internal structure of this patent.

[0054] In the specific design, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, the assembly plate 1 has two or more vertical limiting units 14 integrally machined on it. The lifting coil 2 is assembled on the lifting bracket 21. The limiting units 14 on the assembly plate 1 are designed at the positions corresponding to the outer edges of the lifting coil 2. The limiting unit 14 includes a vertical slide rail 141 that passes through the assembly plate 1. The lifting bracket 21 is provided with a vertical slide bar 211 corresponding to the vertical slide rail 141.

[0055] In this sliding rod-type high-lifespan wireless charging dual-mode switching charger, the limiting structure of the lifting bracket 21 is designed around the lifting coil 2, resulting in more dispersed force distribution. Simultaneously, it is limited by the vertical slide bar 211 and the vertical slide rail 141. This not only makes the structure of the lifting bracket 21 more compact, but also strengthens the lifting bracket. The limiting unit assembling the vertical slide bar 211 adopts a vertically continuous slide rail structure, allowing the lower end of the vertical slide bar 211 to slide directly to the lower part of the assembly plate. This ensures the structural strength of the product while providing more design space to accommodate other product structures, significantly increasing the product's compactness.

[0056] like Figure 10 and Figure 11 As shown, each of the vertical slide rails 141 includes two adjacent vertical slide pieces 1411, and the adjacent edges of the two vertical slide pieces 1411 form a vertical slide rail gap. Figure 12 As shown, the vertical slide bar 211 adopts a slat structure. Figure 8 and Figure 9 As shown, the two sides of the vertical slide bar 211 are vertically slidably assembled with the slide gaps of the two vertical slide pieces 1411. The two adjacent vertical slide pieces 1411 limit the two sides of the slide bar 211, which can prevent the lifting bracket 21 from deflecting in the vertical slide.

[0057] The vertical slide rail 141 structure with two close vertical slide pieces 1411 makes contact with the vertical slide bar 211 a line and surface contact. Compared with surface contact, the friction during movement is greatly reduced. At the same time, when the two close edges of the limiting unit 14 vertical slide pieces 1411 slide with the vertical slide bar 211, if the lifting bracket 21 is subjected to deflection force in the vertical slide rail 141, the deflection force is located entirely at the edge of the vertical slide piece 141. This can prevent the lifting bracket 21 from deflecting in the vertical slide rail 141 more strongly, while ensuring the compactness of the overall structure.

[0058] like Figure 10 and Figure 11 As shown, the two vertical slide plates 1411 of the vertical slide rail 141 are connected by a vertical inner connecting rib 1412, and the cross section of the inner connecting rib 1412 is C-shaped.

[0059] The connecting rib 1412 vertically connects the two vertical slide pieces 1411 within the same limiting unit 14 from the side, making the entire limiting unit 14 more secure on the assembly plate 1. At the same time, the C-shaped inner connecting rib 1412 can make way for the outer side of the vertical slide piece 211, so that the vertical slide piece 211 does not interfere when it slides up and down within it.

[0060] In the specific design, such as Figure 2 and Figure 8 As shown, in the assembled state of the assembly plate 1 and the lifting bracket 21, the assembly plate 1 has three limiting units 14 around the periphery of the lifting bracket 21, with one limiting unit 14 on each side of the assembly plate 1 corresponding to the assembly positions on both sides of the lifting bracket 21. The lifting bracket 21 has vertical outer connecting ribs 212 surrounding the limiting units 14 on both sides, and the cross-section of the outer connecting ribs 212 is also C-shaped. The bending design of the outer connecting ribs 212 greatly increases their strength while ensuring the vertical working space of the limiting units 14 inside the outer connecting ribs 212.

[0061] The sliding bracket 31 has symmetrically arranged horizontal linkage rails 313 on both sides. The lifting bracket 21 has shafts 22 on its outer connecting ribs 212 on both sides that are slidably fitted with the linkage rails 313. During the horizontal sliding of the sliding bracket 31, the lifting bracket 21 moves up and down via the linkage rails 313 and shafts 22. Specifically, when the sliding bracket 31 moves horizontally, the linkage rails 313 follow suit. Since the lifting bracket 21 is limited by the limiting unit 14, it can only slide vertically. By designing the limiting units 14 on both sides of the assembly plate 1, and employing a vertical outer connecting rib 212 structure surrounding the limiting units 14, and designing the shaft 22 structure on the outer surface of the outer connecting rib 212, the linkage rails 313 on both sides of the sliding bracket 31 and the shaft 22 can achieve lateral and vertical sliding. This structure, with the outer connecting rib 212 surrounding the limiting units 14, ensures that the limiting force and driving force of the lifting bracket 21 are located close to each other, allowing the two forces to quickly cancel each other out within the lifting bracket 21. This results in minimal overall stress on the lifting bracket 21, and because they are in the same position, deformation is less likely to occur, significantly improving the assembly lifespan of the lifting bracket 21 and the assembly plate 1. Furthermore, the above structure is very compact, effectively reducing the final size of the charger.

[0062] Furthermore, the vertical sliding plate 1411, the inner connecting rib 1412, and the outer connecting rib 212 on the lifting bracket 21 of the upper limit unit of the assembly plate 1 are all vertically designed with respect to their main body, which facilitates mold opening during injection molding and can effectively reduce processing difficulty and processing costs.

[0063] In the specific design of this embodiment, such as Figure 5 , Figure 8 , Figure 9 The sliding bracket 31 has vertical sliding edges 314 integrally machined on both sides, and the inner sides of the two sliding edges 314 are respectively provided with linkage rails 313, and the linkage rails 313 are provided with inclined sections. When the sliding bracket 31 moves laterally, due to the limiting unit 14 limiting the vertical slide bar 211, the shaft 22 together with the lifting bracket 21 move relative to each other within the inclined section of the linkage rail 313, generating vertical linkage.

[0064] In the specific design, such as Figure 8 , Figure 9 , Figure 10 , Figure 11 As shown, the lifting bracket 21 is mounted on the upper part of the mounting plate 1, and the two sides of the mounting plate 1 are provided with sinking grooves 15 at positions opposite to the vertical outward connecting ribs 212. The limiting unit 14 is mounted in the sinking grooves 15.

[0065] Because the linkage rails 313 on both sides of the sliding bracket 21 are designed in a lower position, the design of the sinkhole 15 makes the overall size of the equipment thinner. At the same time, the bending structure of the sinkhole 15 relative to the main body of the assembly plate 1 makes the entire assembly plate 1 stronger at the sinkhole 15 position, which can more stably withstand the force during the transmission process and improve the service life of the equipment.

[0066] The vertical slide bar 211 and the outer connecting rib 212 extend downwards respectively. The recessed groove 15 has an inner opening 151 and an outer groove 152 penetrating the assembly plate 1, corresponding to the positions of the vertical slide bar 211 and the outer connecting rib 212. The inner opening 151 and the outer groove 152 facilitate the lower ends of the vertical slide bar 211 and the outer connecting rib 212 extending to the lower part of the assembly plate 1, thus greatly increasing the assembly space for each transmission structure and allowing for a thinner overall design of the equipment.
