Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging devices, and particularly relates to a wireless charging device with damping buffer. Background Art

[0002] Since wireless charging devices are very convenient and fast for charging, they have been widely accepted and recognized by people. The principle of wireless charging is the electromagnetic induction principle. Energy is transmitted between the wireless charging device and the electronic device to be charged through a magnetic field. There is no need for a wire connection between the wireless charging device and the electronic device to be charged, and the degree of intelligence is high. It has been widely used in various fields such as smart phones, tablet computers, cars, home and office environments, and medical treatment.

[0003] A wireless charging device with a sliding component usually has a positioning structure but does not have a damping structure. This will cause the sliding component to slide to the positioning point without buffering. When the sliding component is pushed forcefully or quickly, it is easy to collide with the positioning structure, affecting the service life of the overall device. Moreover, the sliding component usually has sliding friction, with a relatively large frictional force and fast wear. In addition, in some rotatable wireless charging devices, the wires inside the wireless charger move around with rotation, easily causing wire wear. Summary of the Utility Model

[0004] In view of this, a wireless charging device with damping buffer that has a long service life, is safe and reliable is provided.

[0005] A wireless charging device with damping buffer includes a wireless magnetic induction charging coil, and also includes a housing, a base, and a sliding component. The sliding component includes a first sliding member and a second sliding member. The housing can be slidably connected to the second sliding member through the first sliding member. A damping member is provided on the surface of the second sliding member facing the base. The surface of the base facing the second sliding member has a sliding contact surface, and a slope is provided at least at a position of a partial sliding stroke of the sliding contact surface. The housing is fixedly connected to the base. When the housing drives the base to slide relative to the second sliding member, the damping member generates a damping effect on the sliding when passing through the slope.

[0006] Further, the slope includes a first slope and a second slope. The slopes of the first slope and the second slope are respectively located at both ends of the sliding contact surface, and a flat slope is provided between the first slope and the second slope. The slopes of the two slopes with respect to the flat slope are equal.

[0007] Furthermore, a limiting groove is also provided on the sliding contact surface. The limiting groove includes a first limiting groove and a second limiting groove. The first limiting groove and the second limiting groove are correspondingly provided outside the first slope and the second slope and correspond to the end point of the sliding stroke.

[0008] Furthermore, the damping member is a soft colloid or an elastic member.

[0009] Furthermore, the first sliding member includes a first fixing portion and a second fixing portion. The first fixing portion is fixed to the housing, the second fixing portion is fixed to the second sliding member, and the first fixing portion is slidably connected to the second fixing portion.

[0010] Furthermore, inner rollers are provided on one side of the second sliding member facing the base, and outer rollers are provided on one side of the base facing the second sliding member. When the housing drives the base to slide relative to the second sliding member, the inner rollers rollingly contact the side surface of the base, and the outer rollers rollingly contact the side surface of the second sliding member.

[0011] Furthermore, at least two outer rollers are included, and at least two inner rollers are included. The two outer rollers and the two inner rollers are symmetrically distributed left and right along the center line of the sliding direction of the second sliding member.

[0012] Furthermore, the wireless charging device further includes a transfer circuit board and a wire groove. The wire groove is snap-fitted and fixed to the second sliding member. The internal rib of the base has a strip-shaped through hole extending along the sliding direction. The side opening of the wire groove communicates with the strip-shaped through hole. The transfer circuit board is fixed to the bottom of the housing and corresponds to the position of the strip-shaped through hole. The wiring of the transfer circuit board passes through the strip-shaped through hole and enters the side opening of the wire groove.

[0013] Furthermore, the wireless charging device includes a first wireless charging module and a second wireless charging module. The first wireless charging module is rotatably connected to the second wireless charging module through the second sliding member. The rotation connection portion between the second sliding member and the second wireless charging module is penetrated. The transfer circuit board and the wire groove are located in the first wireless charging module. The wiring of the transfer circuit board can pass through the wire groove and enter the second wireless charging module.

[0014] Furthermore, a main circuit board is provided in the second wireless charging module. One end of the wiring of the transfer circuit board is electrically connected to the wireless magnetic induction charging coil, and the other end is electrically connected to the main circuit board.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] First, a damping member is provided on the side of the second sliding member facing the base, and a slope is provided on the side of the base facing the second sliding member. The damping member generates a damping effect on the movement when passing through the slope, so that the friction resistance of the sliding component gradually increases when approaching the end point of the sliding stroke, and the movement speed gradually decreases. The sliding component is effectively buffered, and is not likely to collide with the limit groove at the end point of the sliding stroke, which is beneficial to extending the service life of the device.

[0017] Second, an outer roller and an inner roller are provided. When the sliding assembly moves, the inner roller rolls in contact with the side of the base, and the outer roller rolls in contact with the side of the second sliding member. Compared with the traditional sliding assembly, the sliding friction is converted into rolling friction, the friction force is reduced, and the wear is reduced, which is further beneficial to extending the service life of the device.

[0018] Third, the base is provided with a strip through hole, which corresponds to the side opening of the wire trough and the cable end of the adapter circuit board, so that the cable of the adapter circuit board can pass through the strip through hole into the wire trough. By arranging the cable into the wire trough, compared with the traditional method of unfixed wires, the multi-directional movement of the wire is changed to a specific movement along the length of the strip through hole, thereby reducing the wear of the wire.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] See also Figures 1 to 5 , showing a wireless charging device with damping buffer provided by an embodiment of the present utility model, including a wireless magnetic induction charging coil, a housing 1, a base 2 and a sliding assembly, the sliding assembly including a first sliding member 3 and a second sliding member 4, the housing 1 can be slidably connected to the second sliding member 4 through the first sliding member 3, and a damping member 41 is provided on a side of the second sliding member 4 facing the base 2, and a sliding contact surface is provided on the side of the base 2 facing the second sliding member 4, and a slope 21 is provided on the sliding contact surface at least at a position of a part of the sliding stroke, the housing 1 is fixedly connected to the base 2, and when the housing 1 drives the base 2 to slide relative to the second sliding member 4, the damping member 41 produces a damping effect on the sliding when passing through the slope 21.

[0028] Specifically, the slope 21 includes a first slope 211 and a second slope 212. The slope surface of the first slope 211 and the slope surface of the second slope 212 are respectively located at two ends of the sliding contact surface, and a flat slope is provided between the first slope 211 and the second slope 212. Preferably, the two slopes have the same gradient relative to the flat slope.

[0029] More specifically, the sliding contact surface is further provided with a limit groove 22, and the limit groove 22 includes a first limit groove 221 and a second limit groove 222. The first limit groove 221 and the second limit groove 222 are correspondingly arranged on the outside of the first slope 211 and the second slope 212, and correspond to the end points of the sliding stroke.

[0030] Specifically, the damping member 41 is a soft colloid or an elastic member. More specifically, the damping member 41 can be in interference fit with the corresponding assembly hole position to be fixed on the second sliding member 4. Preferably, the end of the damping member 41 in contact with the sliding contact surface is a spherical surface or a conical surface, etc.

[0031] In some specific embodiments, when the outer shell 1 drives the base 2 to slide from the bottom end to the top end of the second sliding member 4, the damping member 41 mounted on the second sliding member 4 remains stationary, and the base 2 moves relative to the damping member 41. First, it disengages from the first limiting groove 221, then successively passes through the first slope 211, the flat slope, and the second slope 212, and finally snaps into the second limiting groove 222 to complete positioning. When passing through the first slope 211 and the second slope 212, the relationship between the damping member 41 and the slope 21 is set as overpressure. The damping member 41 is preferably a wear-resistant elastic member. The damping member 41 elastically contracts. The closer it is to the limiting groove 22, the greater the elastic deformation amount of the damping member 41, the greater the elastic force, and the greater the frictional resistance between the damping member 41 and the slope 21, so that the damping member 41 generates a damping effect on the slope 21 and slides slowly, thereby making it difficult for the outer shell 1 and the base 2 to collide with the second sliding member 4 during the sliding process, which is beneficial to extending the service life of the device.

[0032] Specifically, the first sliding member 3 includes a first fixing portion 31 and a second fixing portion 32. The first fixing portion 31 is fixed to the outer shell 1, the second fixing portion 32 is fixed to the second sliding member 4, and the first fixing portion 31 is slidably connected to the second fixing portion 32.

[0033] Specifically, an inner roller 42 is further provided on one side of the second sliding member 4 facing the base 2, and an outer roller 23 is further provided on one side of the base 2 facing the second sliding member 4. When the outer shell 1 drives the base 2 to slide relative to the second sliding member 4, the inner roller 42 rolls into contact with the side surface of the base 2, and the outer roller 23 rolls into contact with the side surface of the second sliding member 4.

[0034] In some specific embodiments, when the outer shell 1 drives the base 2 to slide from the bottom end to the top end of the second sliding member 4, the two side surfaces of the second sliding member 4 in the sliding direction roll into contact with the outer roller 23, and the two inner side surfaces of the internal ribs of the base 2 in the sliding direction roll into contact with the inner roller 42.

[0035] More specifically, there are at least two outer rollers 23 and at least two inner rollers 42. The two outer rollers 23 and the two inner rollers 42 are symmetrically distributed left and right along the center line of the sliding direction of the second sliding member 4 so that the rolling does not deviate.

[0036] Specifically, the wireless charging device further includes a transfer circuit board 5 and a wire groove 6. The wire groove 6 is snap-fitted and fixed to the second sliding member 4. The internal rib of the base 2 has a strip-shaped through hole 24 extending along the sliding direction. The side opening of the wire groove 6 communicates with the strip-shaped through hole 24. The transfer circuit board 5 is fixed to the bottom of the housing 1 and corresponds to the position of the strip-shaped through hole 24. The wiring 51 of the transfer circuit board 5 passes through the strip-shaped through hole 24 and enters the side opening of the wire groove 6.

[0037] More specifically, the wireless charging device includes a first wireless charging module 7 and a second wireless charging module 8. The first wireless charging module 7 is rotatably connected to the second wireless charging module 8 through the second sliding member 4. The rotation connection between the second sliding member 4 and the second wireless charging module 8 is through. The transfer circuit board 5 and the wire groove 6 are located in the first wireless charging module 7. The wiring 51 of the transfer circuit board 5 can pass through the wire groove 6 and enter the second wireless charging module 8.

[0038] More specifically, a main circuit board is provided inside the second wireless charging module 8. One end of the wiring 51 of the transfer circuit board 5 is electrically connected to the wireless magnetic induction charging coil, and the other end is electrically connected to the main circuit board.

[0039] In summary, a damping member 41 is provided on the surface of the second sliding member 4 facing the base 2, and a slope 21 is provided on the surface of the base 2 facing the second sliding member 4. Through the damping effect on the movement when the damping member 41 passes through the slope 21, the frictional resistance gradually increases and the movement speed gradually decreases when the sliding assembly approaches the end of the sliding stroke, so that the sliding assembly is effectively buffered, and thus it is not easy to collide with the limiting groove 22 located at the end of the sliding stroke, which is beneficial to extending the service life of the device; the outer roller 23 and the inner roller 42 are provided. When the sliding assembly moves, the inner roller 42 rolls and contacts the side surface of the base 2, and the outer roller 23 rolls and contacts the side surface of the second sliding member 4. Compared with the traditional sliding assembly, the sliding friction is changed into rolling friction, the frictional force is smaller, and the wear is smaller, which is further beneficial to extending the service life of the device; the base 2 is provided with a strip-shaped through hole 24, and the strip-shaped through hole 24 corresponds to the side opening of the wire groove 6 and the end of the wiring 51 of the transfer circuit board 5, so that the wiring 51 of the transfer circuit board 5 can pass through the strip-shaped through hole 24 and enter the wire groove 6. By regularizing the wiring 51 into the wire groove 6, compared with the traditional way of unfixed wires, the multi-directional movement of the wires is changed into a specific movement along the length of the strip-shaped through hole 24, reducing the wear of the wires.

[0040] It should be noted that the present invention is not limited to the above embodiments. According to the creative spirit of the present invention, those skilled in the art can also make other changes. These changes made according to the creative spirit of the present invention should be included in the scope of protection required by the present invention.
