[0002] Traditional mobile phones are charged by data cables. With the advancement of technology, wireless charging technology has gradually emerged. Wireless charging technology originates from wireless power transmission technology and can be divided into two types: low-power wireless charging and high-power wireless charging. Low-power wireless charging often uses electromagnetic induction, and high-power wireless charging often uses resonance. Since energy is transmitted between the charger and the power-consuming device through the magnetic field, there is no need for wires to connect the two. Therefore, both the charging device and the power-consuming device can have no exposed conductive contacts.

[0003] Currently, wireless charging devices have poor adjustability and a single charging posture. The electronic products that need to be charged are in a fixed orientation during charging. Due to angle issues, it may be impossible to achieve the purpose of charging and using the products at the same time. Utility Model Content

[0029] In a specific embodiment, the wireless charging stand is suitable for charging any electronic product that accepts wireless charging. Exemplarily, the wireless charging stand is suitable for wireless charging of mobile phones; exemplary, the wireless charging stand is suitable for wireless charging of computer tablets; exemplary, the wireless charging stand is suitable for wireless charging of watches; for ease of explanation, the following exemplary explanation is given by taking the wireless charging stand being suitable for wireless charging of mobile phones as an example.

[0030] Currently, the structure of the wireless charging bracket for mobile phones is fixed and cannot meet the requirements of multi-angle use. Based on the above problems, the present application provides a wireless charging bracket to solve the above problems through the structural design of the wireless charging bracket.

[0031] In some embodiments, Figures 1 to 3 As shown, the wireless charging bracket 100 includes a support rod 110, a connecting ball head 120 and a wireless charging component 130. The support rod 110 includes a first end 111 and a second end 112 along the length direction; the connecting ball head 120 is connected to the first end 111; the wireless charging component 130 has a receiving cavity 132 for accommodating the connecting ball head 120, and the wireless charging component 130 can rotate relative to the connecting ball head 120; wherein, there is a preset angle between the first line segment L1 and the second line segment L2, the first line segment L1 is a line segment between the center point of the first end 111 and the geometric center point of the connecting ball head 120, and the second line segment L2 is a line segment between the center point of the first end 111 and the center point of the second end 112.

[0032] Specifically, the wireless charging bracket 100 is suitable for wireless charging and wireless magnetic charging. Wireless charging uses the principle of electromagnetic induction, and uses the induction between the electromagnetic waves emitted by the transmitter and the receiver to generate electrical energy to complete charging. Wireless magnetic charging uses the principle of magnetic adsorption to adsorb the charger to the back of the mobile phone through magnetic attraction to achieve charging. Since wireless magnetic charging uses the principle of magnetic adsorption, it is more stable and safer than wireless charging. It is not easily affected by external interference, and the charging effect will not be affected by the influence of distance and angle. It also has good anti-slip properties.

[0033] The specific structure of the wireless charging bracket 100 includes a wireless charging component 130, and the wireless charging component 130 includes a wireless charging shell 131. The specific structure of the wireless charging shell 131 is not required to be limited. The surface of the wireless charging shell 131 has a first charging surface 1311, and the wireless charging shell 131 surrounds a cavity, and the cavity accommodates a first wireless charging module 133. The mobile phone is charged by contacting the first charging surface 1311 of the wireless charging shell 131.

[0034] In order to adjust the angle and support the wireless charging component 130, the wireless charging housing 131 has an inwardly recessed accommodating cavity 132. The wireless charging bracket 100 also includes a support rod 110 and a support base 140. The support rod 110 has a first end 111 and a second end 112 along the length direction. The specific length of the support rod 110 is not limited and can be determined according to actual needs. For example, the length of the support rod 110 is 150 mm. The first end 111 of the support rod 110 is connected to the connecting portion 121 of the connecting ball head 120. The connection here includes an integrated fixed connection structure, that is, the support rod 110 and the connecting ball head 120 are a whole, or it can be a structure in which the support rod 110 and the connecting ball head 120 are spliced, and the connecting ball head 120 is a complete sphere, or a hemisphere, or a structural state between a hemisphere and a sphere. By extending the connecting ball head 120 into the accommodating cavity 132 of the wireless charging housing 131, the support rod 110 and the wireless charging housing 131 are installed and matched, and the wireless charging housing 131 can perform multi-angle and refined rotation relative to the connecting ball head 120 when the support rod 110 is stationary. At the same time, the second end 112 of the support rod 110 is connected to the supporting base 140, and the supporting base 140 supports the support rod 110. The connection here includes a movable connection and a fixed connection, and a detailed embodiment will be given later.

[0035] It is further considered that, in order to ensure the installation stability of the wireless charging component 130 and the connecting ball head 120, it is ensured that the wireless charging component 130 cannot be tilted at a large angle. For example, when the wireless charging bracket 100 is placed on a horizontal plane, the extension direction of the support rod 110 is parallel to the vertical direction, and the connecting ball head 120 is arranged along the extension direction of the support rod 110. After the wireless charging shell 131 and the connecting ball head 120 are assembled, the first charging surface 1311 of the wireless charging shell 131 is parallel to the horizontal plane, and the wireless charging shell 131 rotates relative to the connecting ball head 120 so that the first charging surface 1311 has an inclination angle with the horizontal plane. When the angle between the first charging surface 1311 and the horizontal plane exceeds 45 degrees, the wireless charging shell 131 interferes with the connecting portion 121 of the connecting ball head 120, which may limit the further rotation of the wireless charging shell 131. At the same time, there is also the problem of connection stability between the wireless charging component 130 and the connecting ball head 120.

[0036] In order to meet the multi-angle rotation requirements, the first charging surface 1311 of the wireless charging housing 131 can be parallel to the vertical plane, so that the user can use the wireless charging housing 131 while charging. Figure 2 As shown, the connecting ball head 120 is pre-inclined, and the line segment between the center point of the first end 111 and the geometric center point of the connecting ball head 120 and the line segment between the center point of the first end 111 and the center point of the second end 112 form a preset angle. For the convenience of description, it can be understood that the first line segment L1 and the second line segment L2 form a preset angle α1, the first line segment L1 is the line segment between the center point of the first end 111 and the geometric center point of the connecting ball head 120, and the second line segment L2 is the line segment between the center point of the first end 111 and the center point of the second end 112. The specific value of the preset angle α1 can be determined according to actual conditions. For example, the angle α1 between the first line segment L1 and the second line segment L2 is 120 degrees or 140 degrees, or between 120 degrees and 140 degrees. For example, the angle α1 between the first line segment L1 and the second line segment L2 is 135 degrees. If the wireless charging housing 131 is rotated 45 degrees relative to the connecting ball head 120, the first charging surface 1311 can be parallel to the horizontal plane, or the first charging surface 1311 can be parallel to the vertical plane, so as to meet the demand of large tilt angle. The user can adjust the tilt angle of the wireless charging component according to the actual angle demand. The adjustment angle range is wide and the flexibility is high. The first charging surface 1311 is tilted upward, which is convenient for users to use, prevent the mobile phone from falling, and can also achieve the purpose of charging while using. Considering the possibility that the mobile phone may fall off from the wireless charging housing 131, when the first charging surface 1311 is parallel to the vertical plane, a bracket can be set on the wireless charging housing 131 to support the mobile phone, or the first charging surface 1311 is tilted upward, so that the wireless charging housing 131 provides support for the mobile phone, increases the friction between the mobile phone and the wireless charging housing 131, and prevents the mobile phone from slipping.

[0037] The utility model provides a wireless charging bracket, which includes a support rod, a connecting ball head and a wireless charging component. The support rod has a first end and a second end, and the wireless charging component has a receiving cavity. The first end is connected to the connecting ball head and the connecting ball head is inserted into the receiving cavity of the wireless charging component, so that the wireless charging component is connected to the support rod through the connecting ball head. The support rod is used to provide a supporting force for the wireless charging component. The wireless charging component can be rotated at multiple angles relative to the connecting ball head, so that the electronic product charged on the wireless charging component can also be adjusted in angle. It is further considered that the wireless charging component can be finely adjusted in angle relative to the connecting ball head, but In order to ensure the installation stability of the wireless charging component and the connecting ball head, the wireless charging component cannot be tilted at a large angle. In order to meet the need for the charging component to be tilted at a large angle, the connecting ball head is pre-tilted so that a line segment between the center point of the first end and the geometric center point of the connecting ball head and a line segment between the center point of the first end and the center point of the second end form a preset angle. By adopting the tilt angle design in advance and coordinating with the rotation angle of the wireless charging component, the need for a large tilt angle can be met. The user can adjust the tilt angle of the wireless charging component according to the actual angle requirements. The adjustment angle range is wide and the flexibility is high, and the purpose of charging while using can also be achieved.

[0038] In some embodiments, in order to further enhance the flexibility of adjustment of the wireless charging bracket 100, the support base 140 of the wireless charging bracket 100 is connected to the second end 112 of the support rod 110, and the support rod 110 can rotate relative to the support base 140. The rotation here includes the rotation and revolution of the support rod 110. The rotation can be understood as the support rod 110 rotating 360 degrees along the extension direction of the support rod 110. For example, the support rod 110 is a cylindrical structure, the support base 140 has a groove, the support rod 110 is inserted into the groove, the wireless charging housing 131 on the support rod 110 faces the left side, and the support rod 110 rotates 180 degrees, so that the wireless charging housing 131 on the support rod 110 faces the right side. The orientation of the first charging surface 1311 of the wireless charging housing 131 can be quickly adjusted by rotation. Revolution can be understood as that the support rod 110 can rotate relative to the support base 140, and the distance between the wireless charging housing 131 and the support base 140 can be adjusted. For example, the support rod 110 and the support base 140 are connected by a rotating shaft, and the height of the wireless charging housing 131 is adjusted by rotating the support rod 110 so that the height meets the current use requirements. If the wireless charging housing 131 is too high and inconvenient to use, the first end 111 of the support rod 110 is rotated toward the support base 140 to adjust the height. It should be noted that the support rod 110 can rotate relative to the support base 140, which can be only the self-rotation of the support rod 110, or only the revolution of the support rod 110 toward or away from the support base 140, or it can have a structure of both self-rotation and revolution.

[0039] In some embodiments, Figure 3 and Figure 4 As shown, the support rod 110 includes a stretching rod 113 and a sleeve 114, one end of the stretching rod 113 is a first end 111, one end of the sleeve 114 is a second end 112, and the stretching rod 113 can move in the sleeve 114. Specifically, in order to further enhance the flexibility of the wireless charging bracket 100 and quickly adjust the length of the support rod 110, the support rod 110 is a retractable structure, specifically including a stretching rod 113 and a sleeve 114, the sleeve 114 is connected to the support base 140, the stretching rod 113 is connected to the connecting ball head 120, the stretching rod 113 can be inserted into the sleeve 114, and the connection and matching mode of the stretching rod 113 and the sleeve 114 is not limited. For example, the stretching rod 113 and the inner wall of the sleeve 114 are transitionally matched, and the adjustment is performed by overcoming the friction force. There is no limit to the length of the stretching rod 113 and the sleeve 114. The longer the stretching rod 113 and the sleeve 114 are, the wider the range of adjustable lengths is. The specific length can be determined according to actual conditions. When there is no need to adjust the height, most of the stretching rod 113 is located in the sleeve 114. When the height needs to be increased, the stretching rod 113 is gradually extended from the sleeve.

[0040] In some embodiments, Figure 4 As shown, considering the convenience of adjusting the stretching rod 113 in the sleeve 114 and the stability of the connection between the stretching rod 113 and the sleeve 114, the support rod 110 also includes a movable limit member 115 and a positioning member 116. The movable limit member 115 is fixed to the end of the stretching rod 113 away from the connecting ball head 120. One end of the movable limit member 115 is fixed to the stretching rod 113, and the other end of the movable limit member 115 has an expansion structure. The diameter of the stretching rod 113 is smaller than the diameter of the cavity of the sleeve 114, which is convenient for the movement of the stretching rod 113. The expansion structure of the movable limit member 115 abuts against the inner wall of the sleeve 114, and can limit the movement of the stretching rod 113 under a certain degree of force, thereby improving the stability of the connection between the stretching rod 113 and the sleeve 114. At the same time, a positioning piece 116 is installed on the stretching rod 113, and the positioning piece 116 is connected to the sleeve 114. When the stretching rod 113 moves, the positioning piece 116 and the sleeve 114 are fixed, which can prevent the stretching rod 113 from being over-stretched and prevent the stretching rod 113 from slipping out of the sleeve 114.

[0041] In some embodiments, in combination Figure 1 and Figure 5 As shown, in order to meet the demand for charging multiple electronic products at the same time, the wireless charging housing 131 has a receiving cavity, and a first wireless charging module 133 is provided inside the receiving cavity. The wireless charging housing 131 has a first charging surface 1311, and the mobile phone contacts the first charging surface 1311, and the first charging surface 1311 can charge the first mobile phone. At the same time, the supporting base 140 includes a base housing 141, and a second wireless charging module 142 is arranged inside the base housing 141. The base housing 141 has a second charging surface 1411, and the mobile phone contacts the second charging surface 1411, and the second charging surface 1411 can charge the second mobile phone. The two mobile phones are charged at the same time, thereby meeting the demand for charging multiple products at the same time.

[0042] In some embodiments, Figure 5As shown, the base shell 141 also has a plurality of counterweights 143, and the plurality of counterweights 143 are symmetrically arranged about the geometric center point of the second wireless charging module 142. Specifically, considering that the longer the support rod 110 is, the higher the center of gravity of the entire wireless charging bracket 100 is, when charging a mobile phone on the first charging surface 1311 of the wireless charging shell 131, the center of gravity of the wireless charging bracket 100 is further moved upward, especially when the wireless charging shell 131 is rotated relative to the connecting ball head 120, the center of gravity of the entire wireless charging bracket 100 may not be on the support rod 110, and the wireless charging bracket 100 may have a problem of tipping over. In order to improve stability and prevent the wireless charging bracket 100 from tilting, a plurality of counterweights 143 are arranged in the base shell 141, and the weight of the counterweights 143 is used to lower the center of gravity of the wireless charging bracket 100 and improve stability. Taking into account the uncertainty of the rotation direction of the support rod 110, multiple counterweights 143 are evenly arranged in the base shell 141. If there is a second wireless charging module 142 in the base shell 141, the multiple counterweights 143 are symmetrically arranged about the geometric center point of the second wireless charging module 142.

[0043] In some embodiments, Figure 6 As shown, further taking into account the situation that the table top on which the wireless charging bracket 100 is placed is tilted or shaken, an anti-slip structure 1412 is provided on the base shell 141. Any structure that can play an anti-slip role meets the requirements. For example, the anti-slip structure 1412 is an anti-slip rubber strip. Four anti-slip rubber strips are arranged on the base shell 141. The four anti-slip rubber strips are evenly spaced on the contact surface between the base shell 141 and the table top. The friction between the table top and the base shell 141 is increased by the anti-slip rubber strip. When the table top is slightly tilted or slightly shaken, the wireless charging bracket 100 will not slip.

[0044] In some embodiments, Figure 7 As shown, considering that when the wireless charging bracket 100 is used to charge a mobile phone, the first wireless charging module 133 and the second wireless charging module 142 will generate a large amount of heat, in order to quickly dissipate the heat of the first wireless charging module 133 and the second wireless charging module 142, heat dissipation silicone can be attached to the wireless charging coil connection plate, and the heat dissipation silicone can be used for rapid heat dissipation. At the same time, heat dissipation holes 1312 can be provided on the wireless charging housing 131 and the base housing 141. The number and size of the heat dissipation holes 1312 on the wireless charging housing 131 are not limited. For example, three annular heat dissipation holes 1312 are evenly spaced on the wireless charging housing 131.
