[0001] The present application belongs to the technical field of charging equipment, and specifically relates to a charging stand and an adjustment method thereof. Background Art

[0002] In the related technology, wireless charging technology for smart devices such as mobile phones and laptops is developing rapidly. Taking mobile phones as an example, a large amount of heat is generated during the charging process, so the mobile phone needs to be cooled. However, most existing charging devices are directly attached to the back of the mobile phone, which makes it difficult to effectively dissipate heat. In addition, there are many styles of mobile phones. Some styles have a flat back surface, while some styles have a protruding camera on the back. Existing charging stations are difficult to adapt to different models of mobile phones. Summary of the invention

[0003] The present application aims to provide a charging stand and an adjustment method thereof, so as to solve the problem that the existing charging stand has poor heat dissipation effect and is difficult to adapt to different models of mobile phones.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In the first aspect, an embodiment of the present application proposes a charging stand, comprising a base, a cover plate, a support member, a cooling fan and a driving mechanism, wherein the cover plate is fixedly mounted on the base, the support member is movably disposed on the cover plate to support the device to be charged through the cover plate, the base and the support member, the output end of the driving mechanism is connected to the support member to drive the support member to move relative to the cover plate in a direction approaching and away from the cover plate, a cooling channel is formed between the support member and the cover plate, the cooling fan is mounted in the base, and the cooling fan is used to accelerate the airflow in the cooling channel.

[0006] According to a charging stand provided in an embodiment of the present application, the driving mechanism includes a driving motor, and the driving motor is drivingly connected to the supporting member to drive the supporting member to move.

[0007] According to a charging stand provided in an embodiment of the present application, the support member includes a first support member and a second support member, and there are two drive motors, one of which is connected to the first support member, and the other is connected to the second support member.

[0008] According to a charging stand provided in an embodiment of the present application, the support member includes a first support member and a second support member, and there are four drive motors, two of which are installed at opposite ends of the first support member, and the other two drive motors are installed at opposite ends of the second support member.

[0009] According to a charging stand provided in an embodiment of the present application, the cover plate is tilted relative to the vertical surface toward the side where the base is located, and a support plate for supporting a device to be charged is provided at the bottom of the cover plate.

[0010] A charging stand provided according to an embodiment of the present application further includes a distance sensor, which is used to detect the distance between the device to be charged and the cover plate, and the distance sensor is communicatively connected to the driving mechanism.

[0011] According to a charging stand provided in an embodiment of the present application, the distance sensor includes a first distance sensor and a second distance sensor, and the driving mechanism is connected to the first distance sensor and the second distance sensor respectively. When the measurement values ​​of the first distance sensor and the second distance sensor are different, the driving mechanism is used to drive the support member to move so that the measurement values ​​of the first distance sensor and the second distance sensor are equal.

[0012] A charging stand provided in accordance with an embodiment of the present application also includes an inlet temperature sensor and an outlet temperature sensor, wherein the inlet temperature sensor and the outlet temperature sensor are respectively connected to the driving mechanism, and when the temperature difference between the temperature obtained by the inlet temperature sensor and the temperature obtained by the outlet temperature sensor is greater than a first preset value, the driving mechanism is used to drive the support member away from the cover plate; and when the temperature difference is less than a second preset value, the driving mechanism is used to drive the support member closer to the cover plate; wherein the outlet temperature sensor is used to detect the air temperature at the outlet end of the heat dissipation channel, and the inlet temperature sensor is used to detect the heat dissipation channel, and the first preset value is greater than the second preset value.

[0013] A charging stand provided in accordance with an embodiment of the present application also includes a speed sensor, which is used to detect the air flow speed in the heat dissipation channel. The speed sensor is connected to the driving mechanism. When the air flow speed is lower than a first preset flow speed, the driving mechanism is used to drive the support member away from the cover plate; and when the air flow speed is higher than a second preset flow speed, the driving mechanism is used to drive the support member close to the cover plate, wherein the first preset flow speed is less than the second preset flow speed.

[0033] Combine the following Figure 1-Figure 4 The structure of the charging base according to the embodiment of the present application is described.

[0034] like Figure 1 As shown, the charging stand provided in the embodiment of the present application includes a base 1, a cover plate 2, a support member 3, a cooling fan 4 and a driving mechanism. Among them, the base 1 serves as a supporting structure of the entire charging stand and is used to support the cover plate 2. The cover plate 2 is a charging cover plate with a built-in wireless charging coil to provide electromagnetic field energy. The support member 3 is movably arranged on the cover plate 2. When charging, the base 1, the cover plate 2 and the support member 3 support the device to be charged. The driving mechanism is connected to the support member 3 to drive the support member 3 to move relative to the cover plate 2 in a direction close to or away from the cover plate 2. It should be noted that the driving mechanism can only adjust the relative movement between a part of the support member 3 and the cover plate 2, or it can drive the entire support member 3 away from or close to the cover plate 2. A heat dissipation channel for air circulation is formed between the support member 3 and the cover plate 2. The cooling fan 4 is installed in the base 1. The cooling fan 4 can accelerate the airflow in the heat dissipation channel while dissipating heat for the charging stand, thereby dissipating heat for the device 100 to be charged.

[0035] In some embodiments of the present application, Figure 2As shown, two support members 3 are on opposite sides of the cover plate 2. In some other embodiments of the present application, the two support members 3 are located slightly inside the side of the cover plate 2 and are arranged in parallel. In some other embodiments of the present application, there is only one support member 3, and the device to be charged is placed on the cover plate 2 and supported by the cover plate 2 and the support member 3, forming a ventilation channel with a triangular cross-section between the back of the device to be charged and the cover plate 2.

[0036] Optionally, the heat dissipation fan 4 is a centrifugal fan or a cross-flow fan, which is not specifically limited in the embodiment of the present application.

[0037] The device to be charged 100 may be a mobile phone, a laptop computer, a tablet computer, a SLR camera, etc. Of course, the electronic device disclosed in the embodiment of the present application may also be other types of electronic devices, and the embodiment of the present application does not specifically limit the specific types of electronic devices. In order to illustrate the scheme, the following description takes a mobile phone as a specific device to be charged.

[0038] When using, Figure 3 As shown, when the mobile phone is placed on the cover plate 2 for charging, the support member 3 is supported on the back of the mobile phone. If the back of the mobile phone has a protruding camera, after the mobile phone is placed on the charging stand, there is a small gap or even direct contact between the cover plate 2 and the protruding camera, resulting in poor air flow in the heat dissipation channel. For a camera with a larger protrusion, the heat dissipation channel may even be blocked, seriously affecting the heat dissipation effect.

[0039] In the charging stand provided in the embodiment of the present application, the support member 3 moves closer to or away from the cover plate 2 under the action of the driving mechanism to adjust the heat dissipation capacity of the heat dissipation channel. If the back of the mobile phone has a protruding camera, the support member 3 is raised after the mobile phone is placed on the charging stand to ensure the smooth flow of air in the heat dissipation channel and improve the heat dissipation efficiency. Compared with the heat dissipation channel blocked by the protruding camera, the charging stand provided in the present application does not collide with the protruding camera when the air flows in the heat dissipation channel, effectively reducing wind noise and improving the user experience. Under the premise of ensuring the heat dissipation effect, the charging stand can charge both mobile phones with a flat back and mobile phones with a protruding camera on the back, and has a wider range of applications.

[0040] In some specific embodiments of the present application, the driving mechanism includes a driving motor 5, which is connected to the support member 3 in a transmission manner to drive the support member 3 to move. For example, the driving motor 5 is a linear motion motor or an electric push rod, and its driving end is directly fixedly connected to the support member 3. For another example, the driving motor 5 is a rotary motor, and the linear motion of the support member 3 relative to the cover plate 2 is achieved by a motion mechanism that converts rotation into linear motion, such as a ball screw assembly or a threaded transmission structure. It should be noted that the number of the support member 3 and the driving motor 5 can be set as needed, and the embodiments of the present invention do not make specific limitations.

[0041] In some embodiments of the present application, the support member 3 includes a first support member and a second support member, and the first support member and the second support member are respectively connected to a drive motor 5. That is, there are two drive motors 5, one of which is connected to the first support member, and the other is connected to the second support member. The first support member and the second support member can be movably installed on the cover plate 2. When the heat dissipation channel needs to be adjusted, the corresponding support member can be adjusted by the drive motor 5. It can be understood that the two support members can be adjusted at the same time or separately, and the specific setting is based on the actual charging state of the device to be charged.

[0042] In some other embodiments of the present application, the driving mechanism includes four driving motors 5. The driving motor 5 can be a stepper motor or a servo motor. The support member 3 includes a first support member and a second support member, wherein two driving motors 5 are installed at opposite ends of the first support member and are respectively connected to the first support member by transmission, and the other two driving motors 5 are installed at opposite ends of the second support member and are respectively connected to the second support member by transmission. Among them, by setting four driving motors 5, the adjustment method of the support member 3 can be enriched, such as only adjusting the two driving motors 5 located at the same end of the two supports, so that the support member is tilted relative to the initial state, so as to prevent the raised structure on the back of the device to be charged from hindering heat dissipation. For example, the two driving motors 5 installed on the same support member are controlled to drive the support member 3 at the same time, so that a better heat dissipation channel is formed between the raised structure on the back side of the device to be charged and the cover plate 2.

[0043] In some specific embodiments of the present application, the support member 3 is movably mounted in the cover plate 2, and an external thread is provided on the outer side of the support member 3. The outer side of the support member 3 refers to the side of the first support member away from the second support member and the side of the second support member away from the first support member. The motor shaft of each drive motor 5 is provided with a thread structure that is screwed with the external thread.

[0044] Take four drive motors 5 and two support members 3 as an example. When the first end of the support member 3 needs to be adjusted, the drive motor 5 installed at the first end of the support member 3 rotates, and the first end of the support member 3 is raised or lowered by the cooperation of the thread structure and the external thread. At this time, the other two drive motors 5 are immobile, and the second end of the support member 3 is in a fixed state. In some specific embodiments of the present application, the support member 3 is connected to the drive motor 5 through other intermediate parts, as long as the lifting and lowering movement of the support member 3 can be achieved under the rotation of the drive motor 5. In some other embodiments of the present application, the drive motor 5 is fixed on the cover plate 2, and the cover plate 2 is provided with a groove. For example, the seat of the drive motor 5 is fixed in the groove, the support member 3 is a plate with a certain thickness, the support member 3 is located in the groove, and the motor shaft of the drive motor 5 is screwed with the threaded hole set on the support member 3. Under the action of the drive motor 5, the bottom end of the support member 3 is always located in the groove, avoiding the gap between the support member 3 and the cover plate 2 caused by the lifting and lowering of the support member 3. For another example, the drive motor 5 is fixed in the cover plate 2 , the motor shaft of the drive motor 5 penetrates into the groove from the bottom of the groove, the support member 3 is accommodated in the groove and is threadedly connected with the motor shaft of the drive motor 5 .

[0045] The driving mechanism of the charging stand provided in this embodiment includes four driving motors 5, and the four driving motors 5 are arranged at the four ends of the two supporting members 3, so that the height of any end of the supporting member 3 can be adjusted conveniently and flexibly as needed.

[0046] In order to better support the mobile phone, the cover plate 2 is tilted relative to the vertical surface toward the side where the base 1 is located, so that the mobile phone is placed in an inclined state when charging, which is convenient for viewing mobile phone information. A support plate for supporting the device to be charged 100 is provided at the bottom of the cover plate 2. When in use, the top or bottom of the mobile phone contacts the support plate, and the back of the mobile phone is supported by two support members 3, providing better support for the mobile phone through the support plate.

[0047] Based on any of the above embodiments, the charging base further includes a distance sensor, which is used to detect the distance between the device to be charged and the cover plate 2, and the distance sensor is communicatively connected with the driving mechanism.

[0048] In some embodiments of the present application, only one distance sensor is provided. When the measured value detected by the distance sensor is smaller than the preset value, the driving mechanism drives the support member 3 to be raised to improve the ventilation volume and the heat dissipation effect. When the measured value detected by the distance sensor is larger than the preset value, the driving mechanism drives the support member 3 to be lowered to reduce the heat dissipation channel to avoid the airflow escaping in the heat dissipation channel and insufficient contact with the device to be charged under the same wind force.

[0049] like Figure 2As shown, the distance sensor includes a first distance sensor 6 and a second distance sensor 7. The driving mechanism is connected to the first distance sensor 6 and the second distance sensor 7 for communication respectively. When the measured values ​​of the first sensor and the second sensor are different, the driving mechanism is used to drive the support member 3 to move so that the measured values ​​of the first distance sensor 6 and the second distance sensor 7 are equal. When in use, the first distance sensor 6 is used to detect the distance between the device to be charged 100 and the cover plate 2, and the second sensor is used to detect the distance between the raised structure 110 of the device to be charged 100, such as the raised camera, and the cover plate 2. By adjusting the driving mechanism, the size of the heat dissipation channel is made uniform, thereby improving the heat dissipation effect and the stability of placement during charging.

[0050] Taking four drive motors 5 and two support members 3 as an example, the first distance sensor 6 is located at the bottom of the cover plate 2 and corresponds to the camera of the mobile phone when the mobile phone is inverted; the second distance sensor 7 is located at the top of the cover plate 2 and corresponds to the camera of the mobile phone when the mobile phone is placed upright. When the measurement value of the first distance sensor 6 is less than the measurement value of the second distance sensor 7, the two drive motors 5 located at the bottom of the cover plate 2 are controlled to drive the bottom end of the support member 3 away from the cover plate 2 until the measurement values ​​of the two distance sensors are the same. Similarly, when the measurement value of the first distance sensor 6 is greater than the measurement value of the second distance sensor 7, the two drive motors 5 located at the top of the cover plate 2 are controlled to drive the top end of the support member 3 away from the cover plate 2 until the measurement values ​​of the two distance sensors are the same.

[0051] In some other embodiments of the present application, multiple second distance sensors 7 and first distance sensors 6 are respectively arranged along the lateral direction of the cover plate 2. For example, three second distance sensors 7 and three first distance sensors 6 are respectively arranged, and the three first distance sensors 6 are arranged at intervals along the lateral direction of the cover plate 2, wherein the first distance sensors 6 located on both sides are used to measure the distance between the camera set on the side of the mobile phone and the cover plate 2 when the mobile phone is inverted, and the first distance sensor 6 located in the middle is used to measure the distance between the camera located in the middle of the mobile phone and the cover plate 2 when the mobile phone is inverted. The arrangement of the three second distance sensors 7 is similar to that of the three first distance sensors, and will not be repeated. It can be understood that at this time, the driving mechanism adjusts the support member 3 according to the value with the largest difference between the three first distance sensors 6 and the three second distance sensors 7. It can be understood that the adjustment of the driving mechanism according to the detection result of the distance sensor belongs to a single adjustment or a unidirectional adjustment. After the device to be charged 100 is placed on the charging base, at the beginning of the judgment, it is determined which one of the first distance sensors 6 and which one of the second distance sensors 7 has the largest difference. Subsequently, judgment is still made based on the detection values ​​of the two distance sensors. Finally, the adjustment is considered to be in place when the detection results of the two distance sensors are the same.

[0052] For the charging stand provided in the embodiment of the present application, when the measurement values ​​of the first sensor and the second sensor are different, it means that the protrusion on the back of the mobile phone causes an obstacle in the heat dissipation channel or the heat dissipation channel suddenly narrows. At this time, the driving mechanism drives the support member 3 to move closer to or away from the support member 3 until the measurement values ​​of the first distance sensor 6 and the second distance sensor 7 are equal, thereby ensuring smooth flow of air in the heat dissipation channel.

[0053] Based on any of the above embodiments, the charging station further includes an outlet air temperature sensor 8 and an inlet air temperature sensor 9, and the outlet air temperature sensor 8 and the inlet air temperature sensor 9 are respectively connected to the driving mechanism for communication. The outlet air temperature sensor 8 and the inlet air temperature sensor 9 are both installed on the cover plate 2, such as Figure 4 As shown, the air flows upward from the bottom along the heat dissipation channel, the outlet temperature sensor 8 is installed at the outlet of the heat dissipation channel, and the inlet temperature sensor 9 is installed at the inlet of the heat dissipation channel. When the difference between the temperature value b1 detected by the outlet temperature sensor 8 and the temperature value b2 detected by the inlet temperature sensor 9 exceeds the preset range, the driving mechanism drives the support member 3 to move closer to or away from the cover plate 2. It should be noted that at this time, the height adjustment of the support member 3 is an overall lifting and lowering, that is, the two driving motors 5 installed at the opposite ends of the support member 3 are driven synchronously.

[0054] Specifically, when the difference between the temperature value b1 and the temperature value b2 is greater than the first preset value, the difference between the outlet temperature and the inlet temperature is large, that is, the heat generated by the device to be charged 100 is large. At this time, the driving mechanism drives the support member 3 away from the cover plate 2 to make the heat dissipation channel more spacious so as to allow more cold air to pass through and quickly reduce the temperature of the device to be charged 100. When the difference between the temperature value b1 and the temperature value b2 is less than the second preset value, the second preset value is less than the first preset value, then the difference between the outlet temperature and the inlet temperature is small, that is, the cold air in the heat dissipation channel is not fully utilized. At this time, the driving mechanism drives the support member 3 close to the cover plate 2 to narrow the heat dissipation channel so that the cold air passing through can take away sufficient heat and provide utilization of the cold air. When the difference between the temperature value b1 and the temperature value b2 is not greater than the first preset value and not less than the second preset value, the driving mechanism does not operate, that is, no adjustment is made to the support member 3. In one embodiment, the first preset value is 5°C and the second preset value is 3°C. In another embodiment, the first preset value is 6° C., the second preset value is 4° C., or the first preset value and the second preset value are other values, which is not specifically limited in this embodiment of the present application.

[0055] Each time the adjustment is made, the support member 3 can be raised or lowered by a set value. The set value can be 0.5 mm, 1 mm, 1.5 mm, or any value between 0.5 mm and 1.5 mm. It can be understood that after the support member 3 is raised or lowered according to the set value, the difference between the temperature value b1 and the temperature value b2 is continuously monitored. If adjustment is still required, the height of the support member 3 is continuously adjusted until the difference between the two is not greater than the first preset value and not less than the second preset value.

[0056] In addition, the operating power of the cooling fan 4 can also be adjusted according to the detection results of the air outlet temperature sensor 8 and the air inlet temperature sensor 9. For example, when the difference between the temperature value b1 and the temperature value b2 is greater than the first preset value, the operating power of the cooling fan 4 is increased to increase the air flow speed and accelerate the heat dissipation. When the difference between the temperature value b1 and the temperature value b2 is less than the second preset value, the operating power of the cooling fan 4 is reduced to reduce energy consumption. When the difference between the temperature value b1 and the temperature value b2 is not greater than the first preset value and not less than the second preset value, the operating power of the cooling fan 4 is not adjusted. It can be understood that according to the difference between the temperature value b1 and the temperature value b2, the height of the support 3 can be adjusted separately, the operating power of the cooling fan 4 can be adjusted separately, and the height of the support 3 and the operating power of the cooling fan 4 can also be adjusted. The embodiment of the present application does not make specific limitations on this.

[0057] The charging stand provided in the embodiment of the present application detects the temperatures of the inlet and outlet ends of the heat dissipation channel through the inlet temperature sensor 9 and the outlet temperature sensor 8. The driving mechanism adjusts the height of the support member 3 according to the size of the temperature difference. On the one hand, it can effectively improve the heat dissipation effect, and on the other hand, it can also improve the utilization rate of cold air.

[0058] Based on any of the above embodiments, the charging base also includes a speed sensor 10, which is installed on the cover plate 2 to detect the air flow speed in the heat dissipation channel. The speed sensor 10 is connected to the drive mechanism for communication. When the air flow speed is lower than the first preset flow speed, the drive mechanism is used to drive the support member 3 away from the cover plate 2, and when the air flow speed is higher than the second preset flow speed, the drive mechanism is used to drive the support member 3 closer to the cover plate 2. The first preset flow speed is lower than the second preset flow speed. When the air flow speed is not higher than the first preset flow speed and not lower than the second preset flow speed, the drive mechanism does not make any adjustment to the height of the support member 3.

[0059] In one embodiment, the first preset flow rate is 3 m / s, and the second preset flow rate is 5 m / s. In another embodiment, the first preset flow rate is 2.5 m / s, and the second preset flow rate is 4.5 m / s, or the first preset flow rate and the second preset flow rate are other values, which are not specifically limited in the embodiments of the present application.

[0060] like Figure 4 As shown, the speed sensor 10 is installed on the top of the support 3. If the speed sensor 10 detects that the air flow speed is lower than the first preset value, the air in the heat dissipation channel flows slowly and cannot dissipate heat effectively. At this time, the height of the support needs to be raised to prevent heat from accumulating between the device to be charged 100 and the cover 2. If the speed sensor 10 detects that the air flow speed is higher than the second preset value, the air flows too fast and cannot fully contact the heat, and the cold air utilization rate is low. At this time, the driving mechanism lowers the height of the support 3 to ensure that the temperature of the device to be charged 100 is effectively reduced during the air flow process.

[0061] In addition, the operating power of the cooling fan 4 can also be adjusted according to the air flow speed detected by the speed sensor 10. For example, when the air flow speed in the cooling channel is lower than the first preset flow speed, the operating power of the cooling fan 4 is increased to allow more cold air to enter the cooling channel and increase the air flow speed. When the air flow speed is higher than the second preset flow speed, the operating power of the cooling fan 4 is reduced to reduce the energy consumption of the cooling fan 4. When the air flow speed is not higher than the first preset flow speed and not lower than the second preset flow speed, the cooling fan 4 maintains the current power operation. It can be understood that according to the air flow speed in the cooling channel, the height of the support member 3 and the operating power of the cooling fan 4 can be adjusted separately, or both the height of the support member 3 and the operating power of the cooling fan 4 can be adjusted, and this embodiment of the present application does not make specific limitations on this.

[0062] The charging stand provided in this embodiment detects the air flow speed in the heat dissipation channel by means of the speed sensor 10, and the driving mechanism adjusts the height of the support member 3 according to the air flow speed to ensure that the air is in full contact with the device to be charged 100, and the heat is effectively dissipated with the air flow, thereby improving the heat dissipation efficiency.

[0063] The present application also provides a method for automatically adjusting a charging stand, including:

[0064] The device to be charged 100 is placed on the support 3, and a first spacing between the device to be charged 100 and the cover plate 2 and a second spacing between the protruding structure 110 on the device to be charged 100 and the cover plate 2 are obtained. The support 3 is adjusted according to the first spacing and the second spacing so that the adjusted second spacing is equal to the adjusted first spacing. The device to be charged 100 is placed on the support 3 arranged at intervals.

[0065] After the device 100 to be charged, such as a mobile phone, is placed on the support 3, a heat dissipation channel for air flow is formed between the back of the mobile phone, the support 3 and the cover 2. To prevent the protrusion on the charging device from hindering the air flow in the heat dissipation channel, the support 3 is adjusted to form a heat dissipation channel of equal height between each part of the mobile phone and the cover 2. The first spacing and the second spacing can be collected by the first distance detection sensor and the second distance detection sensor in the above embodiment, or by other forms, which is not specifically limited in the embodiment of the present application.

[0066] The automatic adjustment method of the charging stand provided in the embodiment of the present application adjusts the support member 3 so that the first spacing and the second spacing are equal after adjustment, thereby preventing the protruding structure 110 on the charging device from interfering with the air flow in the heat dissipation channel and affecting the heat dissipation effect.

[0067] Based on the above embodiment, the automatic adjustment method of the charging stand further includes: obtaining the air outlet temperature and the air inlet temperature of the heat dissipation channel, and adjusting the height of the support member 3 according to the air outlet temperature and the air inlet temperature.

[0068] Among them, the outlet air temperature and the inlet air temperature of the heat dissipation channel are collected by temperature sensors, see the introduction of the outlet air temperature sensor 8 and the inlet air temperature sensor 9 in the above embodiment for details. The outlet air temperature and the inlet air temperature can be obtained only after the first spacing and the second spacing are adjusted to the same size, or the acquisition can be started at the same time as the first spacing and the second spacing are obtained. It should be noted that the height of the support member 3 is adjusted according to the outlet air temperature and the inlet air temperature only after the first spacing and the second spacing are adjusted to the same size. Adjusting the height of the support member 3 according to the outlet air temperature and the inlet air temperature is to adjust the height of the support member 3 as a whole. Taking the example of providing a drive motor 5 at each opposite end of each support member 3, the height of the support member 3 is adjusted according to the outlet air temperature and the inlet air temperature, and the two drive motors 5 connected to the same support member 3 move synchronously.

[0069] Specifically, if the temperature difference between the outlet air temperature and the inlet air temperature is greater than the first preset value, the heat generated by the device to be charged 100 is relatively large. At this time, the height of the support member 3 needs to be raised to make the heat dissipation channel more spacious so that more cold air can be introduced to quickly reduce the temperature of the device to be charged 100. If the temperature difference between the outlet air temperature and the inlet air temperature is less than the second preset value, and the second preset value is less than the first preset value, the cold air in the heat dissipation channel is not fully utilized. At this time, the height of the support member 3 needs to be lowered to narrow the heat dissipation channel so that the cold air can be introduced to take away sufficient heat and provide utilization of the cold air. If the temperature difference between the outlet air temperature and the inlet air temperature is not greater than the first preset value and not less than the second preset value, the height of the support member 3 does not need to be adjusted. In one embodiment, the first preset value is 5°C and the second preset value is 3°C. In another embodiment, the first preset value is 6°C, the second preset value is 4°C, or the first preset value and the second preset value are other values, which are not specifically limited in the embodiment of the present application.

[0070] Based on any of the above embodiments, the automatic adjustment method of the charging stand further includes: obtaining the air flow speed in the heat dissipation channel, and adjusting the height of the support member 3 according to the air flow speed.

[0071] The air flow velocity is measured by a velocity sensor 10 installed in the heat dissipation channel. The air flow velocity can be obtained only after the first spacing and the second spacing are adjusted to the same size, or it can be obtained at the same time as the first spacing and the second spacing are obtained. It should be noted that the height of the support member 3 is adjusted according to the air flow velocity only after the first spacing and the second spacing are adjusted to the same size. Adjusting the height of the support member 3 according to the air flow velocity is to adjust the height of the support member 3 as a whole.

[0072] Specifically, if the air flow rate is lower than the first preset value, the air in the heat dissipation channel flows slowly and cannot effectively dissipate heat. At this time, it is necessary to raise the height of the support to prevent heat from accumulating between the device to be charged 100 and the cover plate 2. If the speed sensor 10 detects that the air flow rate is higher than the second preset value, the air flows too fast and cannot fully contact the heat, and the cold air utilization rate is low. At this time, it is necessary to lower the height of the support 3 to ensure that the temperature of the device to be charged 100 is effectively reduced during the air flow. When the air flow rate is not higher than the first preset flow rate and not lower than the second preset flow rate, there is no need to make any adjustment to the height of the support 3. In one embodiment, the first preset flow rate is 3m / s and the second preset flow rate is 5m / s. In another embodiment, the first preset flow rate is 2.5m / s, the second preset flow rate is 4.5m / s, or the first preset flow rate and the second preset flow rate are other values, which are not specifically limited in the embodiments of the present application.
