Description

Technical Field

[0001] The utility model relates to the technical field of wireless charging devices, in particular to a vehicle-mounted wireless charger. Background Art

[0002] A wireless charging interface is an interface that uses wireless technology for power transmission. It allows electronic devices to be charged without physical connection. Wearable devices such as smartwatches and earphones have also begun to widely apply wireless charging technology. As an important technological innovation, the wireless charging interface is gradually becoming an indispensable part of emerging electronic devices. From convenient home charging solutions to contactless charging for electric vehicles, the wireless charging interface is shaping a more efficient and environmentally friendly future. With the continuous progress of technology and the increasing market demand, the development prospect of the wireless charging interface will be broader.

[0003] In the prior art, due to various vibrations and bumps that a vehicle experiences during movement, many vehicle-mounted wireless chargers are difficult to keep a mobile phone stable in such an environment, resulting in interrupted charging or reduced efficiency, and even damage to the device due to the movement of the mobile phone. On the other hand, although some vehicle-mounted wireless chargers with clamps on the market can solve the stability problem to a certain extent, their compatibility is often limited. Most of these chargers use a spring clamping mechanism to fix the mobile phone, and this design is mostly only applicable to the size and form of smart phones. For devices with a larger volume or different shapes, such as tablets, these chargers are often inapplicable. Therefore, their practicality is limited by the range of devices they can accommodate. Since the clamping mechanism mostly relies on spring force, this force is a negative feedback, that is, the tighter an object is clamped, the greater the force it exerts against the clamping. This strong clamping will cause excessive pressure on the edge of the mobile phone or the tempered film, resulting in damage or scratches. In the long run, this physical damage affects the appearance and function of the device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a vehicle-mounted wireless charger to solve the disadvantages existing in the prior art.

[0005] To achieve the above object, the present utility model adopts the following technical solution: a vehicle-mounted wireless charger, comprising a substrate and a charging board. Both ends of the charging board are fixed with extension plates. A chute is provided on the front surface of the extension plate. A backing plate is slidably connected to the inner wall of the chute. One end of the backing plate is fixed with a pressing plate. A through groove is provided on the surface of the pressing plate. An internally threaded column is fixed on the front surface of the pressing plate. A rotating column is rotatably connected to the inner wall of the extension plate. One end of the rotating column is fixed with a threaded column. The surface of the threaded column is threadedly connected to the inner wall of the internally threaded column. A preventing circle is fixed at one end of the threaded column. The other end of the rotating column is rotatably connected to a driven rod. One end of the driven rod is rotatably connected to a rotating plate. A push rod is fixed at one end of the rotating plate. The push rod is driven by a cylinder. In the prior art, due to various vibrations and bumps that the vehicle experiences during movement, many vehicle-mounted wireless chargers are difficult to keep the mobile phone stable in such an environment, resulting in charging interruption or reduced efficiency, and even damage to the device due to the movement of the mobile phone. On the other hand, although some vehicle-mounted wireless chargers with clamps on the market can solve the stability problem to a certain extent, their compatibility is often limited. These chargers mostly use a spring clamping mechanism to fix the mobile phone, and this design is mostly only applicable to the size and form of smart phones. For devices with a larger volume or different shapes, such as tablets, these chargers are often not applicable. Therefore, their practicality is limited by the range of devices they can adapt to. Since the clamping mechanism mostly relies on spring force, this force is a negative feedback, that is, the tighter the object is clamped, the greater the force it exerts against the clamping. This strong clamping will cause excessive pressure on the edge of the mobile phone or the tempered film, resulting in damage or scratches. In the long run, this physical damage affects the appearance and function of the device. To solve such problems, the present utility model adopts the method of installing a pressing plate. When the user needs to charge, the device is placed on the backing plate, the charging board supplies power to the device, and at the same time, the cylinder is started to push out the push rod, causing the rotating plate to move to both sides and rotate the rotating column and the threaded column at the same time. The threaded connection between the threaded column and the internally threaded column makes the pressing plate move closer to the charging board. The backing plate slides into the chute, and the pressing plate fixes the device on the surface of the charging board by pressure. Since only the height of the upper and lower ends is restricted, other larger devices, such as tablets, can also be placed horizontally and clamped according to different thicknesses, achieving the effect of improving the user experience and increasing the device adaptability.

[0006] Preferably, a counterweight is fixed on the top of the base plate, a fixing plate is fixed on the front of the counterweight, a hollow column is fixed on the front of the fixing plate, a spring arc piece is fixed on the middle of the inner wall of the hollow column, a shaft is rotatably connected to the inner wall of the hollow column, arc grooves are arranged in a circular array on the circumference of the shaft, the inner wall of the arc grooves is nested with the surface of the spring arc piece, limiting caps are fixed on both ends of the shaft, a fixing peripheral piece is fixed on the circumference of the shaft, and one end of the fixing peripheral piece is fixed to the back of the charging plate. In the prior art, in a vehicle-mounted environment, some wireless chargers are equipped with the function of adjusting the angle, however, the vehicle will inevitably encounter bumps and vibrations during driving, and these external factors greatly affect the angular stability of the mobile phone on the charger. Due to such bumps, even if the user adjusts to an ideal viewing angle before departure, it is difficult to maintain the angle. The problem remains unchanged. When the vehicle passes through uneven roads, accelerates or decelerates, the angle-adjustable wireless charger cannot effectively resist the influence of these external forces, causing the mobile phone to swing up and down or left and right as the vehicle bumps. This not only makes it difficult for users to continuously and clearly observe the screen content, but also distracts driving attention due to frequent adjustments in vision, increasing the hidden dangers of driving safety. To solve this problem, the utility model adopts an installed spring arc piece method to achieve a solution, so that when the user turns the charging plate to adjust the angle, the fixed peripheral part drives the shaft part to rotate. During rotation, the spring arc piece is compressed and elastically deformed, and pops out when it reaches the next arc groove to give feedback to the user. Since the spring arc piece and the arc groove have certain shock resistance and elasticity, and can reset itself before completely leaving the arc groove, a better angle fixing effect can be achieved, thereby improving the user experience.

[0007] Preferably, an anti-collision bar is fixed on the top of the counterweight. In the prior art, when the user adjusts the angle, the bumps of the vehicle may easily cause the charging plate to collide with the counterweight, resulting in wear between components and reducing the service life of the equipment. To address this problem, the utility model adopts the method of installing an anti-collision bar to achieve the buffering effect of the anti-collision bar, reduce the damage caused by the collision, and achieve the effect of increasing the service life of the equipment.

[0008] Preferably, the counterweight is configured as a hollow cube with a triangular cross-section, averaging the product center, while maintaining fixed stability through the triangle to increase the service life of the equipment.

[0009] Preferably, a rubber pad is fixed to the bottom of the base plate to increase the friction between the bottom of the device and the vehicle console, thereby improving the stability of the device.

[0010] Preferably, a placement groove is provided on the top of the base plate to facilitate users to place small items and improve user experience.

[0011] Preferably, an anti-skid groove is provided at the bottom of the rubber pad to increase friction and improve equipment stability.

[0012] Beneficial effects:

[0013] 1. In the prior art, due to various vibrations and bumps that the vehicle experiences during movement, many in-vehicle wireless chargers are difficult to keep the mobile phone stable in such an environment, resulting in charging interruption or reduced efficiency. Moreover, there is even a risk of device damage caused by the movement of the mobile phone. On the other hand, although some in-vehicle wireless chargers with clamps on the market can solve the stability problem to a certain extent, their compatibility is often limited. Most of these chargers use a spring clamping mechanism to fix the mobile phone, and this design is mostly only suitable for the size and form of smart phones. For devices with a larger volume or different shapes, such as tablets, these chargers are often inapplicable. Therefore, their practicality is limited by the range of devices they can accommodate. Since the clamping mechanism mostly relies on spring force, this force is a negative feedback, that is, the tighter the object is clamped, the greater the force it exerts against the clamping. This strong clamping will cause excessive pressure on the edge of the mobile phone or the tempered film, resulting in damage or scratches. In the long run, this physical damage affects the appearance and function of the device. To address such problems, the present utility model solves them by installing a pressing plate. When the user needs to charge, the device is placed on the backing plate, the charging plate supplies power to the device, and at the same time, the air cylinder starts to push out the push rod, causing the rotating plate to move to both sides while rotating the rotating column and the threaded column. The threaded connection between the threaded column and the internal threaded column makes the pressing plate move closer to the charging plate. The backing plate slides into the chute, and the pressing plate fixes the device on the surface of the charging plate through pressure. Since only the height of the upper and lower ends is restricted, other larger devices, such as tablets, can also be placed horizontally and can be clamped according to different thicknesses, achieving the effect of improving the user experience and increasing the device adaptability.

[0014] 2. In the prior art, in the vehicle environment, some wireless chargers are equipped with the function of adjusting the angle. However, the vehicle will inevitably encounter bumps and vibrations during driving. These external factors greatly affect the angle stability of the mobile phone on the charger. Due to this bump, even if the user adjusts to the ideal viewing angle before departure, it is difficult to keep the angle unchanged. When the vehicle passes through uneven roads, accelerates or decelerates, the angle-adjustable wireless charger cannot effectively resist the influence of these external forces, causing the mobile phone to swing up and down or left and right with the bumps of the vehicle. This not only makes it difficult for users to continue to clearly observe the screen content, but also distracts the driver's attention due to frequent adjustments in sight, increasing the hidden dangers of driving safety. In response to such problems, the utility model adopts the method of installing spring arc pieces to solve them, so that when the user turns the charging plate to adjust the angle, the fixed peripheral member drives the shaft member to rotate. During the rotation, the spring arc piece is compressed and elastically deformed, and pops out when it reaches the next arc groove to give feedback to the user. Since the spring arc piece and the arc groove have certain shock resistance and elasticity, and can reset themselves before completely leaving the arc groove, a better angle fixing effect can be achieved, thereby improving the user experience.

[0015] 3. In the prior art, when the user adjusts the angle, the bumps of the vehicle may easily cause the charging plate to collide with the counterweight, resulting in wear between components and reducing the service life of the equipment. To address this problem, the utility model solves it by installing anti-collision strips, thereby achieving the buffering effect of the anti-collision strips, reducing the damage caused by collisions, and achieving the effect of increasing the service life of the equipment.

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following combines specific embodiments and drawings to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model.

[0025] The following describes the specific embodiments of the present utility model with reference to the drawings. Specific embodiment:

[0027] Refer to Figure 1-6, A vehicle-mounted wireless charger, comprising a substrate 1 and a charging board 2. Both ends of the charging board 2 are fixed with extension plates 201. A chute 202 is formed on the front surface of the extension plate 201. A backing plate 2012 is slidably connected to the inner wall of the chute 202. One end of the backing plate 2012 is fixed with a pressing plate 209. A through groove is formed on the surface of the pressing plate 209. An internally threaded column 2011 is fixed to the front surface of the pressing plate 209. A rotating column 203 is rotatably connected to the inner wall of the extension plate 201. One end of the rotating column 203 is fixed with a threaded column 204. The surface of the threaded column 204 is threadedly connected to the inner wall of the internally threaded column 2011. One end of the threaded column 204 is fixed with a preventing circle 2010. The other end of the rotating column 203 is rotatably connected to a driven rod 205. One end of the driven rod 205 is rotatably connected to a rotating plate 206. One end of the rotating plate 206 is fixed with a push rod 207. The push rod 207 is driven by a cylinder 208. Currently, for vehicle-mounted wireless chargers, since the vehicle will experience various vibrations and bumps during movement, many vehicle-mounted wireless chargers are difficult to keep the mobile phone stable in such an environment, resulting in charging interruption or efficiency decline, and even damage to the device due to the movement of the mobile phone. On the other hand, although some vehicle-mounted wireless chargers with clamps on the market can solve the stability problem to a certain extent, their compatibility is often limited. Most of these chargers use a spring clamping mechanism to fix the mobile phone, and this design is mostly only applicable to the size and form of smart phones. For devices with a larger volume or different shapes, such as tablets, these chargers often cannot be applied. Therefore, their practicality is limited by the range of devices that can be adapted. Since the clamping mechanism mostly relies on spring force, this force is a negative feedback, that is, the tighter the object is clamped, the greater the force it resists clamping. This strong clamping will cause excessive pressure on the edge of the mobile phone or the tempered film, resulting in damage or scratches. In the long run, this physical damage affects the appearance and function of the device. It is solved by adopting the method of installing the pressing plate 209. When the user needs to charge, the device is placed on the backing plate 2012. The charging board 2 supplies power to the device. At the same time, the cylinder 208 is started to push out the push rod 207, so that while the rotating plate 206 moves to both sides, the rotating column 203 and the threaded column 204 are rotated. The threaded connection between the threaded column 204 and the internally threaded column 2011 makes the pressing plate 209 approach the charging board 2. The backing plate 2012 slides into the chute 202, and the pressing plate 209 fixes the device on the surface of the charging board 2 by pressure. Since only the height of the upper and lower ends is restricted, other larger devices, such as tablets, can also be placed horizontally and can be clamped according to different thicknesses, achieving the effect of improving the user experience and increasing the device adaptability.

[0028] A counterweight 101 is fixed to the top of the base plate 1, a fixing plate 3 is fixed to the front of the counterweight 101, a hollow column 301 is fixed to the front of the fixing plate 3, a spring arc piece 302 is fixed to the middle of the inner wall of the hollow column 301, a shaft 303 is rotatably connected to the inner wall of the hollow column 301, arc grooves 304 are arranged in a circular array on the circumference of the shaft 303, the inner wall of the arc groove 304 is nested with the surface of the spring arc piece 302, limiting caps 306 are fixed to both ends of the shaft 303, a fixing peripheral piece 305 is fixed to the circumference of the shaft 303, and one end of the fixing peripheral piece 305 is fixed to the back of the charging plate 2. In a vehicle-mounted environment, some wireless chargers are equipped with the function of adjusting the angle. However, the vehicle will inevitably encounter bumps and vibrations during driving. These external factors greatly affect the angular stability of the mobile phone on the charger. Due to this bump, even if the user adjusts to an ideal viewing angle before departure, it is difficult to maintain the angle. The angle remains unchanged. When the vehicle passes through uneven roads, accelerates or decelerates, the wireless charger with adjustable angle cannot effectively resist the influence of these external forces, causing the mobile phone to swing up and down or left and right with the bumps of the vehicle. This not only makes it difficult for users to continue to clearly observe the screen content, but also distracts the driving attention due to frequent adjustments of sight, increasing the hidden dangers of driving safety. The spring arc piece 302 installed is used to solve the problem. When the user turns the charging plate 2 to adjust the angle, the fixed peripheral part 305 drives the shaft part 303 to rotate. During the rotation, the spring arc piece 302 is compressed and elastically deformed, and pops up when it reaches the next arc groove 304 to give feedback to the user. Since the spring arc piece 302 and the arc groove 304 have certain shock resistance and elasticity, and can be reset by itself before completely leaving the arc groove 304, a good angle fixing effect can be achieved, achieving the effect of improving user experience. The counterweight 101 is set as a hollow cube with a triangular cross section, with an average product center, and at the same time, the fixed stability is maintained through the triangle to improve the service life of the equipment. An anti-collision strip 104 is fixed on the top of the counterweight 101. When the user adjusts the angle, the bumps of the vehicle may easily cause the charging plate 2 to collide with the counterweight 101, resulting in wear between components and reducing the service life of the device. This problem is solved by installing an anti-collision strip 104, which achieves the buffering effect of the anti-collision strip 104, reduces the damage caused by the collision, and achieves the effect of increasing the service life of the device. A rubber pad 103 is fixed to the bottom of the base plate 1 to increase the friction between the bottom of the device and the vehicle console and improve the stability of the device. An anti-slip groove is provided at the bottom of the rubber pad 103 to increase friction and improve the stability of the device. A placement groove 102 is provided at the top of the base plate 1 to facilitate users to place small items and improve user experience.

[0029] Working principle of the utility model: When the user needs to charge, place the device on the backing plate 2012, and the charging plate 2 supplies power to the device. At the same time, the cylinder 208 starts to push out the push rod 207, causing the rotating plate 206 to move to both sides while rotating the rotating column 203 and the threaded column 204. The threaded connection between the threaded column 204 and the internal threaded column 2011 makes the pressing plate 209 approach the charging plate 2. The backing plate 2012 slides into the chute 202, and the pressing plate 209 fixes the device on the surface of the charging plate 2 by pressure. Since only the heights of the upper and lower ends are restricted, other larger devices, such as tablet computers, can also be placed horizontally and clamped according to different thicknesses. When the user toggles the charging plate 2 to adjust the angle, the fixed circumferential member 305 drives the shaft member 303 to rotate. When rotating, the spring arc plate 302 is elastically deformed under pressure and pops out when reaching the next arc groove 304, giving feedback to the user. Due to the cooperation between the spring arc plate 302 and the arc groove 304 having certain seismic resistance and elasticity, and it can reset itself before completely leaving the arc groove 304, a better angle fixing effect can be achieved.
