[0068] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0069] The wireless charger includes a charging coil for generating a changing magnetic field. The receiving coil of the device to be charged generates an induced current after obtaining the changing magnetic field, thereby realizing the wireless charging of the device to be charged. In the related art, when the wireless charger is wirelessly charging the device to be charged, the device to be charged may sometimes overheat. The overheating may be caused by excessive charging power and ineffective heat dissipation, or by high external ambient temperature (for example, when charging a car-mounted mobile phone wireless charger, the sun may expose the mobile phone to the sun, causing the temperature of the mobile phone to rise). When the temperature of the device to be charged rises, if effective countermeasures are not taken, the battery life of the mobile phone may be reduced, and in severe cases, the battery may be damaged or even spontaneously combust.
[0070] See also Figure 1-Figure 6The vehicle-mounted charging bracket 10 includes a housing 100, a charging coil 200, a driving assembly 300 and a temperature sensor 700. The housing 100 includes a bearing portion 110, and the bearing portion 110 is suitable for bearing a device to be charged. The device to be charged may be a mobile phone, a watch, a tablet or a computer, or other electronic devices capable of wireless charging. For the sake of convenience of description, the device to be charged is taken as an example of a mobile phone. The mobile phone can be placed on the bearing portion 110 when wireless charging is performed. In some embodiments, the bearing portion 110 can be used only to support the mobile phone, and the mobile phone can be placed at any position on the bearing portion 110. In other embodiments, in addition to supporting the mobile phone, the bearing portion 110 can also be used to locate the relative position of the mobile phone and the bearing portion 110. For example, a groove can be provided on the bearing portion 110, and the mobile phone can be embedded in the groove, so that when the bearing portion 110 carries the mobile phone, the relative position of the mobile phone and the bearing portion 110 is fixed (or the mobile phone can only move within a small range relative to the bearing portion 110), and thus the relative position of the power receiving coil of the mobile phone and the vehicle-mounted charging bracket 10 is fixed. See Figure 6 In this embodiment, the carrying portion 110 is in a flat plate shape and is only used to support a mobile phone. The vehicle-mounted charging bracket 10 can be specifically a vehicle-mounted charging bracket.
[0071] The charging coil 200 is disposed in the housing 100, and the charging coil 200 is suitable for wireless charging of the device to be charged. Specifically, the charging coil 200 can generate a changing magnetic field after being energized, and the receiving coil of the mobile phone generates an induced current after obtaining the changing magnetic field, thereby realizing wireless charging of the mobile phone. When the charging coil 200 is wirelessly charged, it is necessary to match the position of the receiving coil of the mobile phone. The larger the overlapping area of the charging coil 200 and the receiving coil in the direction parallel to the axis of the charging coil 200, the higher the charging power and charging efficiency. Therefore, when the charging coil 200 starts charging, it is necessary to maximize the overlapping area of the charging coil 200 and the receiving coil in the direction parallel to the axis of the charging coil 200, thereby improving the charging power and charging efficiency.
[0072] In order to improve the charging power and charging efficiency, in some embodiments, a charging mark can be set on the carrier 110, and the charging mark marks the best charging position to guide the user to place the mobile phone. After the user places the mobile phone on the carrier 110 according to the marked position, the overlapping area of the power receiving coil and the charging coil 200 is larger, so that the vehicle-mounted charging bracket 10 has better charging power and charging efficiency. However, in the above scheme, the user is required to adjust the relative layout position of the mobile phone and the vehicle-mounted charging bracket 10, and the charging coil 200 is passively matched with the power receiving coil, which has poor reliability, and the user cannot know the specific position of the power receiving coil inside the mobile phone, and it is difficult to ensure the precise matching of the power receiving coil and the charging coil 200. In view of this, see Figure 3 , Figure 6 as well as Figure 7 In this embodiment, the charging coil 200 actively matches the position of the power receiving coil. Specifically, a driving component 300 is provided in the housing 100, and the driving component 300 is connected to the charging coil 200. The driving component 300 is used to drive the charging coil 200 to move. The driving component 300 can drive the charging coil 200 to move to a position that matches the position of the power receiving coil, so that the user does not need to finely adjust the relative position of the mobile phone and the vehicle charging bracket 10 when performing wireless charging, which reduces the user's operation difficulty.
[0073] The temperature sensor 700 is used to detect the temperature of the device to be charged. Specifically, the temperature sensor 700 can directly detect the temperature of the device to be charged, or indirectly detect the temperature of the device to be charged. When the temperature sensor 700 indirectly detects the temperature of the device to be charged, for example, the temperature sensor 700 can indirectly obtain the temperature of the device to be charged by measuring the temperature of the component that is attached to the device to be charged. When the temperature sensor 700 directly detects the temperature of the device to be charged, the temperature sensor 700 can directly obtain the temperature of the device to be charged. Specifically, the temperature sensor 700 can be attached to the device to be charged. In some embodiments, a concave cavity 112 is provided on the side of the bearing part 110 facing the device to be charged, and the bottom of the concave cavity 112 is connected to the accommodating cavity in the housing 100 (the temperature sensor 700 is electrically connected to the first circuit board 410 or the second circuit board 420 through the connecting position), and the temperature sensor 700 is arranged in the concave cavity 112, and the temperature sensor 700 is configured to be suitable for attaching the device to be charged when the bearing part 110 carries the device to be charged. This solution can make the measured temperature of the element to be charged more accurate.
[0074] In this embodiment, the driving component 300 is configured to judge that the device to be charged may be overheated when the temperature sensor 700 monitors that the temperature of the device to be charged is greater than or equal to the second preset temperature (the second preset temperature can be greater than or equal to sixty degrees) during the process of the charging coil 200 charging the device to be charged, and thus reduce the charging power of the charging coil 200 to protect the device to be charged, so that the temperature of the device to be charged will not continue to rise due to the higher charging power, effectively protecting the device to be charged. In addition, unlike the pure electric control method of directly disconnecting the charging or reducing the charging current and charging voltage to reduce the charging power, in the present invention, the charging coil 200 is driven by the driving component 300 to move relative to the device to be charged, thereby reducing the overlapping area between the charging coil 200 and the receiving coil of the device to be charged, thereby reducing the charging power of the driving component. In this solution, since a mechanical drive is used to reduce the charging power, on the one hand, the power adjustment is more stable, and it is not easy for the charging circuit of the vehicle-mounted charging bracket 10 to overheat, which will cause the output power adjustment using a pure electric control method to fail; on the other hand, the power adjustment is more precise, and the output power can be finely adjusted by adjusting the position of the charging coil. When the output power is adjusted using a pure electric control method, the actual output power adjustment is affected by the temperature, and the power error is large.
[0075] In some embodiments, when the current charging is completed, the charging coil 200 can maintain its current position, and when the next charging is performed, the driving component 300 adjusts the charging coil 200 to a position that matches the power receiving coil of the mobile phone. In this solution, the driving component 300 only needs to adjust the position of the charging coil 200 once during one charging process, and the internal operation of the vehicle-mounted charging bracket 10 is simpler. However, the applicant has found that based on inertia, the relative positions of different types of devices to be charged placed on the bearing portion 110 by users are generally not much different (the devices to be charged are generally placed near the center of the bearing portion 110). However, when the vehicle-mounted charging bracket 10 charges different types of devices to be charged, even if the relative positions of different types of devices to be charged and the vehicle-mounted charging bracket 10 are the same, the positions of the power receiving coils in each device to be charged are different, so the relative positions of the power receiving coils and the charging coil 200 will also be different.
[0076] Based on the above principle, by counting the arrangement positions of different types of power receiving coils, assuming that the relative positions of all types of devices to be charged and the carrier 110 are the same, a position with the most suitable total distance from multiple power receiving coils can be found, so that each time the charging coil 200 is charged, it is reset to the above position, so that the charging coil 200 is more convenient to match the power receiving coils of different types of devices to be charged. Specifically, in this embodiment, the driving component 300 is configured to drive the charging coil 200 to move from the charging position to the reset position after the charging coil 200 is charged, wherein the charging position is the position of the charging coil 200 when the device to be charged is powered, and the reset position is the position of the charging coil 200 when it is not powered. In other words, after each charging is completed, the charging coil 200 is reset. Compared with the scheme in which the charging coil 200 remains in the original position (the position of the charging coil 200 when charging) after each charging is completed, the charging coil 200 in this scheme is in a specific position before the next charging starts. Therefore, the specific orientation of the reset position can be designed in advance according to the type of device to be charged that needs to be adapted, so that at the beginning of each charging, the charging coil 200 can move as short a distance as possible to adapt to the position of the receiving element of the device to be charged. The charging response efficiency of the vehicle-mounted charging bracket 10 is higher, the charging preparation time is shorter, and the device to be charged can be charged more quickly.
[0077] It should be noted that, in some embodiments, the position of the charging coil 200 is fixed during wireless charging, in which case the charging position is a single position, that is, the position of the charging coil 200 during charging. In other embodiments, the charging coil 200 may be switched during wireless charging, in which case the charging position is the position of the charging coil 200 when the vehicle-mounted charging bracket 10 generates a signal indicating the end of charging.
[0078] In some embodiments, the reset position may be the position set before the vehicle-mounted charging bracket 10 leaves the factory. The reset position of the vehicle-mounted charging bracket 10 is fixed after leaving the factory and cannot be adjusted. In other embodiments, the reset position may be automatically or manually adjusted based on feedback. For example, the relative position of the power receiving coil and the carrier 110 during wireless charging of the device to be charged may be monitored over a period of time to obtain the user's charging habits. Based on the above data, the optimal reset position is calculated, thereby converting the current reset position into the calculated optimal reset position. After the position conversion, when the subsequent wireless charging ends, it can be reset to the optimal reset position after the conversion.
[0079] Herein, "charging position" and "reset position" are both defined as positions relative to the carrier 110. Moreover, the charging position is a position that is not determined in advance and needs to be determined based on the placement of the device to be charged each time the user charges; while during a single charging process, the reset position is a determined position. In some scenarios, the charging position and the reset position are different positions. In some special scenarios, the charging position and the reset position can be the same position. When the charging position happens to be the same position as the reset position, after charging is completed, the charging coil 200 remains in place.
[0080] The vehicle-mounted charging bracket 10 has a variety of situations in which it indicates "charging is over". In one embodiment, when the vehicle-mounted charging bracket 10 senses that the mobile phone is fully charged, a signal indicating the end of charging can be generated internally. At this time, the driving component 300 drives the charging coil 200 to move from the charging position to the reset position. In another embodiment, when the vehicle-mounted charging bracket 10 senses that the mobile phone is separated from the load-bearing part 110, a signal indicating the end of charging can be generated internally. At this time, the driving component 300 drives the charging coil 200 to move from the charging position to the reset position. In another embodiment, when the vehicle-mounted charging bracket 10 senses charging abnormality, such as abnormal temperature inside the vehicle-mounted charging bracket 10, abnormal temperature of the mobile phone, or abnormal current, voltage and other parameters inside the vehicle-mounted charging bracket 10, a signal indicating the end of charging is generated inside the vehicle-mounted charging bracket 10. At this time, the driving component 300 drives the charging coil 200 to move from the charging position to the reset position. In this embodiment, if the vehicle-mounted charging bracket 10 senses charging abnormality, it can effectively protect the mobile phone by driving the charging coil 200 to reset in time. In this embodiment, if the vehicle-mounted charging bracket 10 senses a charging abnormality, but finds that the charging position coincides with the reset position or the charging position is close to the reset position, a protection position can be set inside the vehicle-mounted charging bracket 10. At this time, the driving component 300 does not drive the charging coil 200 to move to the reset position, but drives the charging coil 200 to move to the protection position, thereby effectively protecting the mobile phone.
[0081] The driving assembly 300 can drive the charging coil 200 to move along a straight line, move along a curve, rotate along a curve, or both move and rotate along a curve. Figure 6-Figure 9 , the driving component 300 drives the charging coil 200 to move back and forth along a straight line. In this embodiment, on the one hand, the structure of the driving component 300 is simpler, and on the other hand, the movement dimension of the charging coil 200 is lower, which is more convenient for quickly matching the relative position of the charging coil 200 and the receiving coil.
[0082] When the driving component 300 reciprocates in a straight line, the reset position can be located in the middle or end of the motion stroke. In some embodiments, the driving component 300 is configured to drive the charging coil 200 to reciprocate in a straight line along the first direction X. The reset position is located at the end position along the first direction X within the stroke of the charging coil 200. In this embodiment, before each charging starts, the charging coil 200 is located at the end position within its motion stroke. After charging starts, the driving component 300 only drives the charging coil 200 to move in the first direction X or the reverse direction of the first direction X to match the relative position with the power receiving coil. The charging coil 200 does not need to move back and forth during the position matching process. The maximum moving distance of the charging coil 200 during the matching process is the maximum moving stroke of the charging coil 200 along the first direction X. Compared with the reset position being located in the middle of the charging stroke motion stroke, the maximum delay in the charging preparation process is lower. For example, in this embodiment, when the power receiving coil is located at the end position of the movement stroke of the charging coil 200 and at an end different from the reset position, the charging delay of the vehicle-mounted charging bracket 10 is the longest, and during the matching process of the charging coil 200, the charging coil 200 needs to move its maximum stroke along the first direction X. When the reset position of the charging coil 200 is located in the middle of its movement stroke, if the charging coil 200 goes in the wrong direction during the matching process, it needs to perform a return movement during its movement. At this time, the movement distance of the charging coil 200 may be greater than its maximum stroke along the first direction X, so the charging preparation time is longer.
[0083] When the driving component 300 drives the charging coil 200 to reciprocate along a straight line parallel to the first direction X, in some embodiments, the first direction X can be perpendicular to the direction from the bearing portion 110 to the device to be charged, or can be parallel to the direction from the bearing portion 110 to the device to be charged. When the first direction X is perpendicular to the direction from the bearing portion 110 to the device to be charged, the driving component 300 drives the charging coil 200 and the power receiving coil of the device to be charged to be staggered to reduce the overlapping area. When the first direction X is perpendicular to the direction from the bearing portion 110 to the device to be charged, the driving component 300 drives the charging coil 200 and the power receiving coil of the device to be charged to be away from the power receiving coil, which can also reduce the charging power. In a further embodiment, the charging power of the charging coil 200 can be reduced to zero. See. Figure 6-Figure 9 In this embodiment, the first direction X is perpendicular to the direction from the carrying portion 110 to the device to be charged.
[0084] In other embodiments, the driving assembly 300 is configured to drive the charging coil 200 to rotate around a first axis, the first axis being parallel to the direction from the carrier 110 to the device to be charged; or the first axis being perpendicular to the direction from the carrier 110 to the device to be charged. Both of the above embodiments can reduce the charging power of the charging coil 200.
[0085] The specific structure of the drive assembly 300 depends on actual needs, see Figure 6-Figure 9 ,as well as Figure 11-Figure 12 In some embodiments, the driving assembly 300 includes a driving unit 310 and a transmission unit 320 connected to the driving unit 310. The transmission unit 320 includes a support seat 324, and the support seat 324 is connected to the charging coil 200. The vehicle-mounted charging bracket 10 also includes a guide rail 500, the axis of the guide rail 500 is parallel to the first direction X, the support seat 324 includes a first slider 3242 slidably connected to the guide rail 500, and the driving unit 310 drives the support seat 324 to reciprocate along the first direction X on the guide rail 500. Through the sliding cooperation between the guide rail 500 and the first slider 3242, the movement of the support seat 324 can be smoother. In some embodiments, the two ends of the guide rail 500 may be connected to fixed protrusions. In this case, the fixed protrusions at the two ends of the guide rail 500 are not only used to fix the guide rail 500, but also used to limit the movement range of the first slider 3242. When the first slider 3242 moves along the first direction X to abut against one of the fixed protrusions, the support seat 324 moves to one of the end positions within its movement range. When the first slider 3242 moves in the reverse direction of the first direction X to abut against another fixed protrusion, the support seat 324 moves to the other end position within its movement range. In addition, in this embodiment, when the first slider 3242 moves to abut against one of the fixed protrusions, the position of the charging coil 200 is the reset position.
[0086] See also Figure 6-Figure 7 ,as well as Figure 11-Figure 12 In some embodiments, the vehicle charging bracket 10 includes two guide rails 500 arranged relatively along the second direction Y, and the support seat 324 includes two first sliders 3242. The two first sliders 3242 are slidably connected to the two guide rails 500 in a one-to-one correspondence. The axes of the two guide rails 500 are parallel to the first direction X, and the two guide rails 500 are relatively distributed at intervals along the second direction Y. By providing two guide rails 500, the guidance of the support seat 324 is more stable.
[0087] See also Figure 6-Figure 7 ,as well as Figure 11-Figure 12In some embodiments, the transmission part 320 further includes a screw 323, the axis of the screw 323 is parallel to the first direction X, and the support seat 324 includes a second slider 3243 sleeved on the screw 323, and the second slider 3243 has an internal thread that cooperates with the screw 323. The screw 323 is inserted into the second slider 3243, and bearings are provided at both ends of the screw 323. When the driving part 310 drives the screw 323 to rotate, the second slider 3243 is driven by the screw 323 to reciprocate along the axis direction of the screw 323 (i.e., the first direction X), so that the support seat 324 as a whole reciprocates along the first direction X, and then the charging coil 200 reciprocates along the first direction X. In this embodiment, the support seat 324 is driven by the screw 323, and the driving stability and driving accuracy are higher.
[0088] To further improve the drive accuracy, see Figure 11-Figure 12 In some embodiments, the driving unit 310 may include a driving motor, a first gear 321 and a second gear 322. The driving motor may be a stepping motor, so that the driving accuracy is higher. The first gear 321 is connected to the output shaft of the stepping motor, the second gear 322 is connected to the end of the screw 323, and the first gear 321 is meshed with the second gear 322. During the driving process, the stepping motor drives the first gear 321 to rotate, the first gear 321 drives the second gear 322 to rotate, the second gear 322 drives the screw 323 to rotate, and the screw 323 drives the support seat 324 to translate along the first direction X. Specifically, the number of teeth of the first gear 321 is less than the number of teeth of the second gear 322, so that the rotation speed of the screw 323 is less than the rotation speed of the stepping motor, thereby improving the driving accuracy.
[0089] See also Figure 6 as well as Fig.12 , the support seat 324 also includes a support plate 3241, two first sliders 3242 are connected to one side of the support plate 3241 along the first direction X, and the two first sliders 3242 are correspondingly connected to the two sides of the support plate 3241 along the second direction Y. The second slider 3243 is connected to the other side of the support plate 3241 along the first direction X (i.e., the side opposite to the two first sliders 3242). In this solution, the support seat 324 forms a three-point positioning, and the transmission is more stable compared to the structure in which the screw rod 323 is arranged on the side of the two guide rails 500. The screw rod 323 is located on one side of the two guide rails 500 along the first direction X, and along the second direction Y, the screw rod 323 is located between the two guide rails 500. In other words, in this embodiment, when observed along the first direction X, the screw 323 is located between the two guide rails 500, and in this embodiment, when observed along the second direction Y, the screw 323 is located on one side of the two guide rails 500. In this solution, the distance between the second slider 3243 and the two first sliders 3242 along the first direction X is longer, so that the positioning of the support seat 324 is more stable.
[0090] The charging coil 200 translates along the first direction X to achieve position matching with the receiving coil. When the receiving coil deviates from the charging coil 200 along the second direction Y, the matching degree between the charging coil 200 and the receiving coil is not ideal no matter where the charging coil 200 moves along the first direction X. In view of this, see Figure 6 as well as Figure 8-Figure 9 In some embodiments, the support base 324 further includes a support plate 3241, and the charging coil 200 is disposed on a side of the support plate 3241 facing the carrier 110. The guide rail 500, the first slider 3242, the screw 323, the second slider 3243 and the driving unit 310 are all disposed on a side of the support plate 3241 away from the carrier 110. In this solution, since the charging coil 200 and the guide rail 500, the first slider 3242, the screw 323, the second slider 3243 and the driving unit 310 are distributed on different sides of the support plate 3241, the guide rail 500, the first slider 3242, the screw 323, the second slider 3243 and the driving unit 310 will not occupy the space of the charging coil 200 along the second direction Y, and the size of the charging coil 200 along the second direction Y can be maximized. Therefore, when the mobile phone is placed on the carrier 110 in a deviated manner along the second direction Y, the overlapping area between the charging coil 200 and the power receiving coil of the mobile phone can also be maximized, thereby improving the charging power and charging efficiency. Further, the size of the charging coil 200 along the second direction Y can be substantially equal to the size of the inner cavity of the housing 100 along the second direction Y. For example, along the second direction Y, the distance between the two sides of the charging coil 200 and the inner wall of the housing 100 can be less than or equal to two millimeters.
[0091] See also Figure 3 , Figure 6 , Figure 7 , Fig. 9 as well as Fig.10In some embodiments, the vehicle-mounted charging bracket 10 further includes a first circuit board 410 disposed between the support base 324 and the charging coil 200. The first circuit board 410 is electrically connected to the charging coil 200 and is used to transmit electrical signals to the charging coil 200 or obtain electrical signals generated by the charging coil 200. In order to reduce the thickness of the vehicle-mounted charging bracket 10 (i.e., the dimension along the third direction Z), the support base 324 has a first wall surface 3245 facing the bearing portion 110, the charging coil 200 is attached to the first wall surface 3245, the first wall surface 3245 is concave with a recessed groove, and the first circuit board 410 is disposed in the recessed groove and is electrically connected to the charging coil 200. In this solution, on the one hand, by providing a sinking groove, the overall thickness of the support plate 3241 and the first circuit board 410 can be reduced, thereby reducing the overall thickness of the vehicle-mounted charging bracket 10; on the other hand, since the first circuit board 410 sinks into the sinking groove, the charging coil 200 can be attached to the support plate 3241. Compared with the structure in which the charging coil 200 is completely attached to the first circuit board 410, in order to achieve the same support area for the charging coil 200, the size of the first circuit board 410 in this embodiment can be smaller, thereby reducing the material cost of the first circuit board 410. In the above embodiment, the first circuit board 410 is fixed to the support seat 324. In other embodiments, the first circuit board 410 can also be fixed to the housing 100, and a wire is provided between the first circuit board 410 and the charging coil 200, and the wire is bent to leave a compensation margin, so that the charging coil 200 and the first circuit board 410 can be electrically connected to each other and both can produce relative movement.
[0092] See also Figure 8-Figure 10 In some embodiments, the vehicle-mounted charging bracket 10 further includes a second circuit board 420, which is electrically connected or electrically isolated from the first circuit board 410 (the two are not electrically connected), and the two together realize the control of the internal components of the vehicle-mounted charging bracket 10. The first circuit board 410 can control the charging coil 200 and the infrared sensor, and the second circuit board 420 is used to control the driving assembly 300. In order to facilitate the electrical connection between the two, the sink groove can at least partially penetrate the support seat 324, and the first circuit board 410 is electrically connected to the second circuit board 420 through the part of the support plate 3241 penetrated by the sink groove. And, see Figure 6 as well as Fig. 9, the first circuit board 410 includes a second wall 411 away from the charging coil 200, and the second wall 411 includes an electrical connection area exposed in the sink, and the electrical connection area is connected to an electronic component 412, which can be a resistor, capacitor, inductor or processing chip. In this scheme, the position where the electronic component 412 needs to be set on the first circuit board 410 is set to make the sink penetrate, which on the one hand avoids the position interference between the electronic component 412 and the support plate 3241, and on the other hand can further reduce the overall thickness of the first circuit board 410 and the support plate 3241. In addition, the second circuit board 420 can also be electrically connected to the electrical connection area, so as to facilitate the position arrangement of the intermediate wire. In this embodiment, two circuit boards are used to control the internal components of the vehicle charging bracket 10, and the first circuit board 410 is connected to the charging coil 200 and moves synchronously with the charging coil 200, and the second circuit board 420 is fixedly connected to the housing 100. Compared with the structure of using one circuit board to control all the internal components of the vehicle charging bracket 10, the control effect of the charging coil 200 is better.
[0093] See also Figure 6 In some embodiments, the carrying part 110 includes a light-transmitting panel 111, which is used to carry the device to be charged, and the charging coil 200 is visible on the light-transmitting panel 111. In this solution, the user can observe the specific position of the charging coil 200 through the light-transmitting panel 111. On the one hand, the user can place the mobile phone according to the specific position of the charging coil 200 observed, which is convenient for the user to actively match the relative position of the power receiving coil and the charging coil 200; on the other hand, when the driving component 300 fails, the charging coil 200 can be found in time when it fails to reset to the reset position after charging is completed, so as to repair the vehicle-mounted charging bracket 10 in time. In addition, in particular, when the vehicle-mounted charging bracket 10 is a mobile phone vehicle-mounted bracket, the user may not know whether the mobile phone vehicle-mounted bracket can be wirelessly charged. For example, when the vehicle is rented by the user, it is impossible to accurately understand whether the charging bracket on the vehicle can be wirelessly charged. The setting of the light-transmitting panel 111 makes the charging coil 200 visible from the outside, and the user can understand the wireless charging function of the vehicle-mounted mobile phone bracket by observing the structure of the charging coil 200.
[0094] In order to improve the visibility of the charging coil 200 in a dark environment, in some embodiments, the vehicle-mounted charging bracket 10 further includes a light-emitting element 430. The light-emitting element 430 is used to illuminate the interior of the housing 100 so that the user can observe the specific position of the charging coil 200 in the housing 100. When the light-emitting element 430 is provided in the housing 100, in one embodiment, the light-transmitting panel 111 can be set so that the charging coil 200 is not visible when the light-emitting element 430 is turned off (that is, the light-transmitting panel 111 is a colored translucent panel), so that the appearance of the vehicle-mounted charging bracket 10 is more concise when it is not working; when the light-emitting element 430 is turned on, the charging coil 200 is visible, so that the user can observe the position of the charging coil 200. In other embodiments, the light-transmitting panel 111 can also be a completely transparent transparent panel, for example, the light-transmitting panel 111 can be a transparent glass panel or a transparent acrylic panel, so that the charging coil 200 can be seen on the light-transmitting panel 111 regardless of whether the light-emitting element 430 is turned on.
[0095] The light emitting element 430 may be disposed at any position in the housing 100 that can illuminate the charging coil 200. In some embodiments, the light emitting element 430 may be connected to the housing 100 and fixed in position, and does not move with the charging coil 200. Figure 3 as well as Figure 6 In some embodiments, the light emitting element 430 is disposed inside the charging coil 200 and is electrically connected to the first circuit board 410. In this solution, on the one hand, since the light emitting element 430 moves with the charging coil 200, the lighting effect of the charging coil 200 is better; on the other hand, since the light emitting element 430 is disposed inside the charging coil 200, the lighting effect of the light emitting element 430 on various parts of the charging coil 200 is more uniform, and the light emitting element 430 can more reasonably utilize the internal space of the charging coil 200, making the internal structure of the vehicle-mounted charging bracket 10 more compact.
[0096] In order to improve the lighting effect of the charging coil 200, in some embodiments, the shape of the light-emitting element 430 can be circular, the light-emitting element 430 is located on the inner side of the charging coil 200 and the center of the light-emitting element 430 coincides with the center of the charging coil 200, or the light-emitting element 430 is arranged around the outer side of the charging coil 200 and the center of the light-emitting element 430 coincides with the center of the charging coil 200.
[0097] See also Figure 3 , Figure 6 as well as Figure 11-Figure 12In some embodiments, the vehicle-mounted charging bracket 10 further includes a sensor 440, and the sensor 440 is used to detect whether the carrying part 110 carries a device to be charged. The sensor 440 can be used to generate a signal indicating the start of charging (the vehicle-mounted charging bracket 10 can also generate a signal indicating the start of charging in other ways). The specific type of sensor 440 depends on actual needs. In some embodiments, the sensor 440 is a pressure sensor 440, which is used to detect the pressure on the carrying part 110. When the sensor 440 detects that the pressure on the carrying part 110 increases, it is determined that the carrying part 110 has carried a mobile phone, so a signal indicating the start of charging is generated. In other embodiments, when the carrying part 110 includes a translucent panel 111, the sensor 440 can be an infrared sensor, which is used to emit infrared rays. When the mobile phone is carried on the translucent panel 111, the infrared rays are blocked and reflected. At this time, the infrared sensor generates a signal indicating the start of charging. In a further embodiment, the sensor 440 is disposed inside the charging coil 200. In this solution, the arrangement position of the sensor 440 is more reasonable, and the internal space of the charging coil 200 can be reasonably utilized, making the internal structure of the vehicle-mounted charging bracket 10 more compact.
[0098] When the mobile phone has a fixed relative position with the carrier 110 each time it is charged, the position matching of the charging coil 200 and the receiving coil is more accurate. Figure 3 , Figure 6 as well as Figure 11-Figure 12 In some embodiments, the vehicle-mounted charging bracket 10 further includes a positioning assembly 600, which is connected to the housing 100. The positioning assembly 600 is used to position the device to be charged so as to fix the relative position between the device to be charged and the carrying portion 110. In this solution, after the mobile phone is carried on the carrying portion 110, the position of the mobile phone is fixed by a fixing device, and after the position of the mobile phone is fixed, the position of the mobile phone and the carrying portion 110 is fixed. In other words, the addition of the positioning assembly 600 allows the position of the mobile phone to be relatively fixed with the carrying portion 110 each time wireless charging is performed. After the position of the mobile phone and the carrying portion 110 is fixed, the position of the power receiving coil of different models of mobile phones changes within a smaller range. On the one hand, it can be more convenient for the position design of the reset position, and on the other hand, it can shorten the moving distance of the charging coil 200 during the charging preparation process.
[0099] In order to achieve the positioning of the mobile phone, in some embodiments, the positioning component 600 can be an annular flange connected to the carrying part 110. When the mobile phone is positioned on the carrying part 110, it can be embedded in the annular flange to achieve the position fixation with the carrying part 110. In other embodiments, the positioning component 600 can include a magnet, and the magnet can achieve the fixation of the mobile phone by adsorbing the magnetic attraction component on the mobile phone. Figure 6-Figure 7In some embodiments, the positioning assembly 600 may be a gravity bracket. Specifically, the positioning assembly 600 includes a supporting portion 610, a first clamping arm 620, and a second clamping arm 630. The supporting portion 610 is suitable for supporting the device to be charged. The portion of the supporting portion 610 used for supporting the device to be charged is located outside the housing 100, and the end of the supporting portion 610 opposite to the portion used for supporting the device to be charged extends into the housing 100. The supporting portion 610 is connected to the lower end of the housing 100, and its upper end is inserted into the housing 100. The supporting portion 610 is configured to be displaced downward relative to the bearing portion 110 by the gravity of the device to be charged, and a portion of the upper end of the supporting portion 610 gradually extends out of the housing 100 when the supporting portion 610 moves downward. In the process of the upper end of the supporting portion 610 extending out of the housing 100, the first clamping arm 620 and the second clamping arm 630 are driven to move in directions toward each other, so that the first clamping arm 620 and the second clamping arm 630 are suitable for jointly clamping the lateral sides of the device to be charged. After the positioning assembly 600 positions the mobile phone, the supporting part 610 can position the bottom of the mobile phone, the first clamping arm 620 and the second clamping arm 630 position the lateral sides of the mobile phone, and the bearing part 110 positions the back plate of the mobile phone. In this embodiment, the three sides of the mobile phone are all positioned, and the user does not need to adjust the positioning direction during the positioning process, so the positioning process is simpler and the positioning accuracy is higher.
[0100] When the positioning assembly 600 is a gravity bracket, in some embodiments, see Fig.13 , a sensing component may be provided on the supporting portion 610 of the gravity support to sense whether the bearing portion 110 is carrying a mobile phone. Specifically, a magnetic element 611 may be provided on the portion of the supporting portion 610 extending into the housing 100. The magnetic element 611 may be a permanent magnet or an electromagnet. The magnetic element 611 is capable of generating a magnetic field, and the magnetic element 611 is coupled to the charging coil 200. When the mobile phone is placed on the gravity support, the supporting portion 610 moves downward, thereby driving the magnetic element 611 to move. At this time, the charging coil 200 cuts the magnetic flux lines generated by the magnetic element 611, and then the charging coil 200 generates an induced current. After the first circuit board 410 obtains the above signal, it determines that the mobile phone is carried on the bearing portion 110, and then generates a signal indicating the start of charging. In this solution, only one magnetic element 611 (such as a magnet) needs to be added to determine whether the mobile phone is carried on the carrying part 110. Compared with the structure of setting components such as pressure sensors 440 or infrared sensors, the cost is lower. In addition, the solution of adding the magnetic element 611 does not need to change the structural layout of the electronic components 412 on the first circuit board 410, and the modification cost is lower.
[0101] In another embodiment, see Figure 14-15, a micro switch 612 may also be provided in the vehicle-mounted charging bracket 10, and the micro switch 612 is connected to the housing 100. A contact protrusion 613 is provided on the side of the portion of the supporting portion 610 located in the housing 100, and the contact protrusion 613 is configured to separate from the micro switch 612 when the supporting portion 610 does not support the mobile phone, and the micro switch 612 is closed at this time. In other words, when the supporting portion 610 is configured to be displaced downward to the lowest point relative to the bearing portion 110 by the gravity of the device to be charged, the contact protrusion 613 presses and closes the micro switch 612. When the supporting portion 610 supports the mobile phone, it moves downward and presses the micro switch 612. The micro switch 612 is electrically connected to the first circuit board 410 or the second circuit board 420, and the first circuit board 410 or the second circuit board 420 generates a signal indicating the start of charging after sensing that the micro switch 612 is closed. In this solution, the movement of the supporting portion 610 is used to sense whether the mobile phone is carried on the bearing portion 110, and the sensing is more accurate. In this solution, the micro switch 612 can generate not only a signal indicating the start of charging, but also a signal indicating the end of charging. Specifically, when the supporting portion 610 does not support the device to be charged, the abutting protrusion 613 is separated from the micro switch 612, and when the micro switch 612 is separated from the abutting protrusion 613, the first circuit board 410 or the second circuit board 420 generates a signal indicating the end of charging.
[0102] When the vehicle-mounted charging bracket 10 includes a gravity bracket, and the vehicle-mounted charging bracket 10 is a vehicle-mounted charging bracket. When the vehicle-mounted charging bracket is used to carry a mobile phone, the charging coil 200 is exposed to sunlight, and the temperature may be too high, causing the internal components to age and break. In view of this, in some embodiments, see Figure 1 , a shading plate 800 may be provided in the housing 100, and the shading plate 800 is located on the side of the charging coil 200 facing the light-transmitting panel 111. The driving assembly 300 is also configured to drive the charging coil 200 to move to a position blocked by the shading plate 800 when the temperature sensor 700 senses that the temperature of the charging coil 200 is greater than or equal to a first preset temperature (the first preset temperature may be greater than the second preset temperature, and the first preset temperature may be greater than or equal to seventy degrees), so that when the vehicle-mounted charging bracket 10 is not working, the charging coil 200 will not be exposed to the sun and the temperature will rise and thus age, thereby improving the service life of the vehicle-mounted charging bracket 10. It should be noted that the temperature sensor 700 may be an independent sensor or a combination of multiple sensors. When the temperature sensor 700 is an independent sensor, the sensor can simultaneously detect the temperature of the device to be charged and the temperature of the charging coil 200. When the temperature sensor 700 is a combination of multiple sensors, one of the sensors may detect the temperature of the device to be charged, and the other sensor may detect the temperature of the charging coil 200.
[0103] The shading plate 800 has a variety of arrangements. In some embodiments, the shading plate 800 is located in the housing 100, and along the direction from the charging coil 200 to the bearing portion, the shading plate 800 is located between the charging coil 200 and the bearing portion 110. In this solution, the shading effect of the shading plate 800 is better. Further, in this embodiment, the projection plane is perpendicular to the direction from the bearing portion 110 to the charging coil 200, the light-transmitting panel 111 forms a first projection on the projection plane, and the shading plate 800 forms a second projection on the projection plane, and the first projection is staggered from the second projection. In this solution, the shading plate 800 is not visible outside the light-transmitting panel 111, making the appearance of the vehicle-mounted charging bracket more regular. In other embodiments, the bearing portion 110 includes a shading plate 800, which is suitable for carrying a device to be charged, and the side of the shading plate 800 is connected to the side of the light-transmitting panel 111. In this solution, the thickness of the vehicle-mounted charging bracket 10 can be reduced.
[0104] In some embodiments, the shading plate 800 is provided with a through hole, and the infrared sensor is configured to face the through hole when the charging coil 200 moves to a position blocked by the shading plate 800. In this solution, even if the shading plate 800 blocks the charging coil 200, the infrared sensor can well sense whether the carrying part 110 carries a device to be charged through the through hole, and the infrared sensor is more sensitive.
[0105] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0106] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or", "and / or" or "and / or" appears in the full text, its meaning includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
[0107] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
