Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, and more specifically, to a sliding structure for a wireless charger. Background Technology

[0002] With the development of technology and the improvement of living standards, mobile phones have become necessities in people's lives. Wireless charging technology for mobile phones is also becoming increasingly mature. Wireless charging technology achieves wireless power transmission through electromagnetic induction. In electromagnetic induction-based wireless charging, the positions of the coils at the transmitting and receiving ends greatly affect the coil coupling, significantly impacting charging efficiency. To improve charging performance, wireless chargers with adjustable coil positions have emerged on the market. These chargers use a drive device to move the coil linearly, ensuring alignment between the coil and the receiving coil in the device being charged. Existing chargers typically use a sliding structure with a metal rail and slider, resulting in surface friction. This friction is high, making them prone to jamming, and the large gaps between components lead to insufficient stability. Furthermore, vibrations during movement can cause abnormal noises, affecting the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a sliding structure for a wireless charger. The structure is reasonable, which can reduce the friction of sliding, avoid jamming, and ensure tight cooperation between components, making the movement more stable, avoiding noise generation, and improving the user experience.

[0004] A sliding structure for a wireless charger includes a base and a sliding assembly. The base includes a partition with a track groove. The sliding assembly includes a sliding seat. The partition has a first groove parallel to the track groove on a first surface facing the sliding seat. The lower end face of the sliding seat has a first rolling element that abuts against the first groove. The partition has a second groove on a second surface away from the sliding seat. The sliding seat has an extension that passes through the track groove and extends below the second surface. The extension has a second rolling element that abuts against the second groove.

[0005] In the above technical solution, the first surface is provided with a first groove parallel to the track groove, and the first rolling element abuts against the first groove. Simultaneously, the second surface is provided with a second groove, and an extension portion passes through the track groove and extends below the partition. The extension portion is provided with a second rolling element abutting against the second groove. When the sliding seat moves along the track groove, the first and second rolling elements roll along the first and second grooves respectively, causing rolling friction between the sliding seat and the base. This effectively reduces the friction between them, making the movement of the sliding seat smoother and quieter. The first and second rolling elements cooperate to clamp the partition from both sides in the height direction, thereby limiting the sliding seat in the height direction. This makes the connection between components tighter, preventing the sliding seat from swaying or vibrating during movement, further improving the stability and quietness of the sliding seat.

[0006] Furthermore, there are two first slide grooves, which are located on both sides of the track groove, and the first rolling elements are correspondingly disposed on both sides of the sliding seat.

[0007] In the above technical solution, the first slide groove is set as two grooves, and the two sides of the slide seat are respectively provided with first rolling elements corresponding to the first slide groove, so that both sides of the slide seat can be stably supported, further improving the stability of the slide seat movement.

[0008] Furthermore, there are two second slide grooves, which are located on both sides of the track groove, and the second rolling elements are correspondingly disposed at both ends of the extension.

[0009] In the above technical solution, the second slide groove is set as two, and the two ends of the extension are respectively provided with second rolling elements corresponding to the second slide groove, so that the structure of the sliding seat is more stable.

[0010] Furthermore, both the first rolling element and the second rolling element are spherical, with the first rolling element embedded in the sliding seat and the second rolling element embedded in the extension.

[0011] In the above technical solution, the spherical first and second rolling elements enable rolling friction between the sliding seat and the base, effectively reducing the friction between the two and improving the stability and quietness of movement.

[0012] Furthermore, the bottom of the sliding seat extends downward to form a connecting seat for connecting the drive device, the connecting seat passing through the track groove.

[0013] In the above technical solution, the connecting seat can be connected to the driving device, and the driving device drives the sliding seat to slide along the track groove, thereby realizing the movement of the coil.

[0014] Furthermore, the second surface is provided with a plurality of support ribs, which are arranged on both sides of the track groove.

[0015] In the above technical solution, the supporting ribs can improve the structural strength of the partition, reduce the deformation of the partition during assembly, and thus ensure product quality.

[0016] Furthermore, the track groove has notches on both sides for the extension to pass through.

[0017] In the above technical solution, the notch allows the extension to pass through, making assembly more convenient and faster.

[0018] Furthermore, both the first and second slides are plastic channels integrally formed with the base.

[0019] In the above technical solution, the first and second slides are integrally formed with the base, which reduces costs. The plastic material reduces the coefficient of friction, improving movement stability and reducing noise.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The first surface is provided with a first groove parallel to the track groove, and the first rolling element abuts against the first groove. Simultaneously, the second surface is provided with a second groove, and an extension portion passes through the track groove and extends to below the partition plate. The extension portion is provided with a second rolling element abutting against the second groove. When the sliding seat moves along the track groove, the first and second rolling elements roll along the first and second grooves respectively, resulting in rolling friction between the sliding seat and the base. This effectively reduces the friction between the two, making the movement of the sliding seat smoother and quieter. The first and second rolling elements cooperate to clamp the partition plate from both sides in the height direction, thereby limiting the sliding seat in the height direction. This makes the connection between the components tighter, preventing the sliding seat from swinging or vibrating during movement, further improving the stability and quietness of the sliding seat.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] Please refer to Figures 1 to 5 In a preferred embodiment, the sliding structure of the wireless charger of the present invention mainly includes a base 1 and a sliding component 2. The base 1 includes a partition 11, and the partition 11 has a track groove 12. The sliding component 2 includes a sliding seat 21. The first surface 111 of the partition 11 facing the sliding seat 21 has a first sliding groove 113 parallel to the track groove 12. The lower end surface of the sliding seat 21 has a first rolling element 22 that abuts against the first sliding groove 113. The second surface 112 of the partition 11 away from the sliding seat 21 has a second sliding groove 114. The sliding seat 21 has an extension 24 that passes through the track groove 12 and extends to the lower part of the second surface 112. The extension 24 has a second rolling element 23 that abuts against the second sliding groove 114.

[0031] For example, the sliding seat 21 has a cavity inside, and the coil is disposed in the cavity. The base 1 has a circuit board (not shown) connected to the coil. The track groove 12 is formed in a straight line. The first surface 111 has a first groove 113 parallel to the track groove 12. The first rolling body 22 abuts against the first groove 113. At the same time, the second surface 112 has a second groove 114. The extension 24 passes through the track groove 12 and extends to the bottom of the partition 11. The extension 24 has a second rolling body 23 abutting against the second groove 114. When the sliding seat 21 moves along the track groove 12, the first rolling body 22 and the second rolling body 23 roll along the first groove 113 and the second groove 114 respectively, so that there is rolling friction between the sliding seat 21 and the base 1, which can effectively reduce the friction between the two and make the movement of the sliding seat 21 more stable and quiet. The first rolling element 22 and the second rolling element 23 cooperate to clamp the partition 11 from both sides in the height direction, thereby limiting the sliding seat 21 in the height direction, making the connection between the components tighter, preventing the sliding seat 21 from swinging or vibrating during movement, and further improving the stability and quietness of the sliding seat 21.

[0032] In this embodiment, there are two first slide grooves 113, which are located on both sides of the track groove 12, and the first rolling elements 22 are correspondingly disposed on both sides of the sliding seat 21. By setting two first slide grooves 113 and providing first rolling elements 22 on both sides of the sliding seat 21 corresponding to the first slide grooves 113, both sides of the sliding seat 21 can be stably supported, further improving the stability of the sliding seat 21's movement.

[0033] In this embodiment, there are two second slide grooves 114, which are located on both sides of the track groove 12, and the second rolling elements 23 are respectively disposed at both ends of the extension 24. By setting two second slide grooves 114 and providing second rolling elements 23 at both ends of the extension 24 corresponding to the second slide grooves 114, the structure of the sliding seat 21 is made more stable.

[0034] Both the first rolling element 22 and the second rolling element 23 are spherical. The first rolling element 22 is embedded in the sliding seat 21, and the second rolling element 23 is embedded in the extension 24. The spherical first rolling element 22 and the second rolling element 23 enable rolling friction between the sliding seat 21 and the base 1, effectively reducing the friction between the two, improving the stability of movement, and avoiding noise generated during movement.

[0035] The bottom of the sliding seat 21 extends downward to form a connecting seat 25 for connecting the drive device, and the connecting seat 25 passes through the track groove 12. The connecting seat 25 can be connected to the drive device, and the drive device drives the sliding seat 21 to slide along the track groove 12, thereby realizing the movement of the coil. It is understood that the drive device can be an existing linear drive device, which will not be described in detail here.

[0036] The second surface 112 is provided with a plurality of support ribs 13, which are arranged on both sides of the track groove 12. For example, one side of the support rib 13 is connected to the second surface 112 and the other side is connected to the inner circumferential surface of the base 1. The support ribs 13 can improve the structural strength of the partition 11, reduce the deformation of the partition 11 during assembly, and thus ensure product quality.

[0037] The track groove 12 has notches 14 on both sides for the extension 24 to pass through. Understandably, the notches 14 can be set to at least two sets, and the distance between the two sets of notches 14 matches the distance between the two extensions 24, so that the extensions 24 can pass through the track groove 12, making the assembly more convenient and faster.

[0038] In this embodiment, both the first slide groove 113 and the second slide groove 114 are integrally formed plastic grooves with the base 1. The integral forming of the first slide groove 113 and the second slide groove 114 with the base 1 reduces costs. The plastic material reduces the coefficient of friction, which is beneficial for movement stability and also reduces noise.
