DETAILED DESCRIPTION
[0026] It should be noted that, in the absence of conflict, the embodiments and technical features in the embodiments of the present application can be combined with each other, and the detailed description in the specific implementation method should be understood as an explanation of the purpose of the present application and should not be regarded as an improper limitation on the present application.
[0027] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the embodiments of the present application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly including at least one feature. In the description of the embodiments of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically limited.
[0028] The present application embodiment provides a wireless charger. Figures 1 to 5 The wireless charger 100 includes a wireless charging module (not shown in the figure), a support rod 2 and a shell. An adjusting member 2a is provided on the support rod 2. The wireless charging module is arranged in the shell, and a rotating part 31 is arranged in the shell. The rotating part 31 forms a rotating cavity 31a, and a protruding port 31b connected to the rotating cavity 31a is formed on the peripheral side of the rotating part 31. A part of the adjusting member 2a can be rotatably arranged in the rotating cavity 31a, and a part of the adjusting member 2a passing through the protruding port 31b is used to contact the wall surface of the protruding port 31b to limit the rotation of the shell.
[0029] The wireless charger 100 provided in the present application is provided with an adjusting member 2a on the support rod 2, and a wireless charging module is provided in a shell. The wireless charging module is used for charging electronic devices. A rotating portion 31 is provided in the shell. The rotating portion 31 forms a rotating cavity 31a. Part of the adjusting member 2a can rotate in the rotating cavity 31a. In this way, on the one hand, the adjusting member 2a located in the rotating cavity 31a can be protected to a certain extent and its service life can be improved; on the other hand, through the rotation cooperation of the adjusting member 2a and the rotating cavity 31a, the angle between the shell and the support rod 2 can be adjusted to better meet the user's requirements for the placement of the electronic device, with high convenience of use and good user experience. By forming an extension port 31b connected to the rotating cavity 31a on the peripheral side of the rotating portion 31, the portion of the adjusting member 2a passing through the extension port 31b can be used to contact the wall surface of the extension port 31b to limit the rotation angle of the shell. That is to say, when the shell is rotated to a certain angle in a certain direction, the portion of the adjusting member 2a passing through the extension port 31b will abut against the wall surface of the extension port 31b to limit the shell from continuing to rotate in this direction. In this way, not only can the situation where the adjusting member 2a falls out of the rotating cavity 31a due to excessive rotation of the shell be reduced, but also the situation where the wires of the wireless charging module are damaged by being pulled or bent due to excessive rotation can be reduced, thereby increasing their service life.
[0030] For example, in one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 or Figure 5 The housing includes a shell 3 and a cover body. A receiving cavity 3a and an installation opening 3b are formed in the shell 3. The rotating part 31 is arranged in the receiving cavity 3a, and the cover body covers the installation opening 3b.
[0031] Exemplarily, in one embodiment, a charging area corresponding to the wireless charging module is provided on the surface of the housing, and the electronic device can be charged in the charging area.
[0032] Exemplarily, in one embodiment, the wireless charger 100 includes a magnet, which can be arranged around the periphery of the wireless charging module, and a magnet or iron sheet is also arranged in the electronic device, so that the electronic device can be stably attracted.
[0033] Exemplarily, in one embodiment, a coil is provided in the wireless charging module, and a variable magnetic field can be generated by energizing the coil. A coil is also provided inside the electronic device. Through the principle of electromagnetic induction, the coil in the electronic device generates current after receiving the variable magnetic field emitted by the coil in the wireless charging module, so as to charge the battery in the electronic device.
[0034] Exemplarily, in one embodiment, the electronic device may be a mobile phone, a tablet, a watch, or a headset, etc.
[0035] In one embodiment, please refer to Figures 1 to 3 The adjusting member 2a includes a ball head 2a1 and a limiting member 2a2. The ball head 2a1 is arranged at one end of the supporting rod 2, the limiting member 2a2 is arranged on the ball head 2a1, the ball head 2a1 is rotatably arranged in the rotating cavity 31a, and the limiting member 2a2 is passed through the extending port 31b.
[0036] For example, the ball head 2a1 can be sleeved on the outer periphery of one end of the support rod 2, and the stopper 2a2 can be arranged on the outer peripheral surface of the ball head 2a1. In this way, by the rotational cooperation between the ball head 2a1 and the rotation cavity 31a, universal adjustment can be achieved to meet more rotation directions of the housing, further improving the convenience of use, and the stopper 2a2 is arranged through the extension opening 31b to prevent the housing from rotating excessively, which is safe.
[0037] In one embodiment, please refer to Figure 2 The rotating part 31 is formed with an insertion port 31c and a through port 31d which are connected to the rotating cavity 31a. The diameter of the ball head 2a1 is larger than the caliber of the through port 31d, and the diameter of the ball head 2a1 is smaller than the caliber of the insertion port 31c. The insertion port 31c is connected to the extension port 31b, and the limit member 2a2 enters the extension port 31b through the insertion port 31c.
[0038] Here, when the support rod 2 is passed through the insertion port 31c and the through port 31d in turn, the ball head 2a1 can pass through the insertion port 31c because the diameter of the ball head 2a1 is smaller than the caliber of the insertion port 31c, and the limiting member 2a2 located on its outer peripheral surface can also pass through the insertion port 31c and enter the protruding port 31b because the insertion port 31c is connected to the protruding port 31b. When the ball head 2a1 moves to the through port 31d, the ball head 2a1 cannot pass through because the diameter of the ball head 2a1 is larger than the caliber of the through port 31d, thereby ensuring that the ball head 2a1 can rotate stably in the placement cavity and the limiting member 2a2 can perform the limiting work stably.
[0039] In one embodiment, please refer to Figure 1 and Figure 2 The extension opening 31b has a first wall surface 31b1 and a second wall surface 31b2 along the circumference of the insertion opening 31c. The first wall surface 31b1 and the second wall surface 31b2 are used to abut against the stopper 2a2 when the housing rotates.
[0040] Here, the first wall surface 31b1 can be a wall surface for limiting the position of the shell by rotating counterclockwise along the circumference of the plug port 31c, and the second wall surface 31b2 can be a wall surface for limiting the position of the shell by rotating clockwise along the circumference of the plug port 31c, that is, when the limiting member 2a2 rotates to the second wall surface 31b2, it cannot continue to rotate in the current direction, or when the limiting member 2a2 rotates to the second wall surface 31b1, it cannot continue to rotate in the current direction. In this way, not only can the situation that the shell falls off due to excessive rotation along the circumference of the plug port 31c be reduced, but also the wires of the wireless charging module and the like can be pulled or bent due to excessive rotation, resulting in damage, thereby increasing their service life.
[0041] In one embodiment, please refer to Figure 1 and Figure 2 The arrangement direction of the plug port 31c and the through port 31d is the first direction, and the wall of the extension port 31b away from the plug port 31c along the first direction is the third wall 31b3, and the third wall 31b3 is used to contact and limit with the limit member 2a2 when the shell rotates.
[0042] In this way, when the shell rotates along the first direction toward the plug port 31c, the third wall 31b3 can abut against the limit piece 2a2 to limit its continued rotation. In this way, it can not only reduce the situation where the shell rotates excessively along the first direction toward the plug port 31c and causes it to fall off, but also reduce the damage caused by pulling or curling of the wires of the wireless charging module and the like due to excessive rotation, thereby increasing its service life.
[0043] It should be noted that the circumferential direction of the plug port 31c may be a direction of rotation around the first direction as an axis.
[0044] It should be noted that Figure 1 R1 may be a first direction, and R2 may be an up-down direction.
[0045] For example, in one embodiment, the through hole 31d is located along a direction on a side of the plug-in port 31c away from the wireless charging module. In this way, the electronic device to be charged can be avoided, and the space utilization rate is good.
[0046] Exemplarily, in one embodiment, the shape of the housing is not limited. For example, the projection of the housing along the first direction may be a circle.
[0047] Exemplarily, in one embodiment, the shape of the support rod 2 is not limited. For example, the support rod 2 may be cylindrical or in other rod shapes.
[0048] Exemplarily, in one embodiment, the shape of the limiting member 2a2 is not limited. For example, the limiting member 2a2 may be in a long strip state to extend substantially along the first direction and be connected to the outer peripheral surface of the ball head 2a1.
[0049] Exemplarily, in one embodiment, the shape of the rotating portion 31 is not limited, for example, it can be roughly hemispherical to better fit the ball head 2a1.
[0050] In one embodiment, please refer to Figure 2 , the cross-sectional area of the rotating cavity 31a along the direction perpendicular to the first direction gradually decreases from the insertion port 31c to the through-port 31d, and the ball head 2a1 contacts the cavity wall of the rotating cavity 31a. In this way, during the rotation of the housing, since the cross-sectional area of the rotating cavity 31a along the direction perpendicular to the first direction gradually decreases from the insertion port 31c to the through-port 31d, the shape of the ball head 2a1 can be better adapted to produce a damping effect, thereby achieving hovering of the rotation angle.
[0051] In one embodiment, please refer to Figure 4 and Figure 5 The wireless charger 100 includes a damping member 5 , which is disposed on the rotating portion 31 and is used for damping cooperation with the adjusting member 2 a .
[0052] Exemplarily, an annular shell 32 is provided in the outer shell, and the annular shell 32 is spaced apart on the outer periphery of the rotating part 31 to define an annular cavity 32a, and the annular cavity 32a can be arranged to penetrate along the first direction, and the damping member 5 is arranged in the annular cavity 32a, and the damping member 5 forms a damping cavity 5a, and the damping cavity 5a is arranged to penetrate along the first direction to facilitate the insertion and installation of the support rod 2, and the part of the ball head 2a1 passing through the plug-in interface 31c can be arranged in the damping cavity 5a, and the diameter of the opening of the damping cavity 5a on the side away from the plug-in interface 31c along the first direction is smaller than the diameter of the ball head 2a1, so that the ball head 2a1 cannot pass through the opening.
[0053] In this way, by arranging the damping member 5 to contact and cooperate with the adjusting member 2a, the housing can be further suspended when rotated to a preset angle, thereby reducing shaking when taking and placing the electronic device, and providing a good user experience.
[0054] Exemplarily, in one embodiment, the annular cavity 32a, the rotating cavity 31a and the damping cavity 5a are coaxially arranged.
[0055] For example, in one embodiment, please refer to Figure 2 and Figure 4 The ring shell 32 is formed with a limiting groove 32b on the circumferential side thereof, which is connected to the ring cavity 32a. The damping member 5 is formed with a limiting protrusion 5b on the outer circumference thereof, and the limiting protrusion 5b is engaged with the limiting groove 32b. In this way, the limiting protrusion 5b is engaged with the limiting groove 32b, so that when the housing rotates along the circumferential direction of the plug-in interface 31c, a better damping effect can be provided to the ball head 2a1, and the damping member 5 can be reduced from falling off.
[0056] Exemplarily, in one embodiment, the number of the limiting protrusions 5b and the limiting grooves 32b is not limited. For example, the number of the limiting protrusions 5b and the limiting grooves 32b can be two each. The two limiting protrusions 5b are arranged at intervals along the circumference of the damping member 5, and the two limiting grooves 32b are correspondingly arranged. Each limiting protrusion 5b is snap-fitted with the corresponding limiting groove 32b. In this way, the connection strength between the damping member 5 and the outer shell can be further improved to better provide the damping effect.
[0057] For example, in one embodiment, please refer to Figure 4 and Figure 5 The wireless charger 100 includes a baffle 6 and a fastener. A first positioning hole 6a is formed in the circumference of the baffle 6. A mounting position 32c is formed in the outer circumference of the annular shell 32. A second positioning hole 32c1 is formed in the mounting position 32c. The fastener is passed through the first positioning hole 6a and the second positioning hole 32c1 so that the baffle 6 abuts against the damping member 5. In this way, the damping member 5 can be limited along the first direction to reduce the possibility that the damping member 5 is separated from the ball head 2a1 during the rotation of the shell.
[0058] In one embodiment, please refer to Figure 1 and Figure 3 The wireless charger 100 includes a base 7, a support rod 2 connected between the base 7 and the housing, and one end of the support rod 2 having an adjustment member 2a is tilted.
[0059] Here, by setting the support rod 2 between the base 7 and the shell, the base 7 is used to provide a support point, and the end of the support rod 2 provided with the adjustment member 2a is tilted. In this way, on the one hand, a certain avoidance can be formed for the rotation of the shell to reduce the structural interference between the shell and the support rod 2; on the other hand, the heat dissipation space for the electronic device can be increased to improve the heat dissipation effect; on another hand, the tilted setting of the support rod 2 also makes it convenient for users to take, place and watch the electronic device.
[0060] In one embodiment, please refer to Figure 1 and Figure 3 The support rod 2 includes a first rod 21, a second rod 22 and a third rod 23. The first rod 21 is connected to the base 7, the second rod 22 is connected between the first rod 21 and the third rod 23, the adjustment member 2a is sleeved on one end of the third rod 23 away from the second rod 22, and the first angle between the second rod 22 and the third rod 23 is between 30° and 60°.
[0061] Exemplarily, the first rod 21 can be fixedly arranged on the base 7, the first rod 21 can extend in the up-down direction, the first direction and the up-down direction can cross or overlap, a receiving cavity is formed in the first rod 21, a part of the second rod 22 is inserted in the receiving cavity, another part of the second rod 22 can extend in the up-down direction and be connected to the third rod 23, and the adjusting member 2a can be sleeved on an end of the third rod 23 away from the second rod 22. The first angle between the second rod 22 and the third rod 23 is the angle at which the housing rotates toward the base 7 in the up-down direction, see Figure 3 The first angle A is the angle between the central axis of the second rod 22 and the central axis of the third rod 23. The angle between the second rod 22 and the third rod 23 can be 30°, 40°, 50° or 60°, etc. Thus, by setting a suitable angle, on the one hand, the heat dissipation space for the electronic device can be increased and the heat dissipation effect can be improved; on the other hand, it is convenient for users to take and watch the electronic device, and the user experience is good.
[0062] In one embodiment, the angle between the second rod 22 and the third rod 23 is 45°, which can further improve the heat dissipation effect and facilitate user operation.
[0063] Exemplarily, in one embodiment, one end where the second rod 22 and the third rod 23 are connected is hemispherical.
[0064] In one embodiment, the base 7 has a socket for inserting an external power source, and a wiring channel is formed in the support rod 2. The wires of the wireless charging module are electrically connected to the circuit board in the socket through the wiring channel to power the wireless charging module.
[0065] Exemplarily, the first rod 21 forms a first wiring channel, the second rod 22 forms a second wiring channel, and the third rod 23 forms a third wiring channel. The wires of the wireless charging module pass through the first wiring channel, the second wiring channel, and the third wiring channel to be electrically connected to the circuit board in the socket in the base 7 to supply power to the wireless charging module. In this way, the wires of the wireless charging module can be hidden in the wiring channel to avoid exposure, which improves the safety of use and improves the simplicity and aesthetics of the appearance of the wireless charger 100.
[0066] For example, in one embodiment, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A notch 23b is formed at the portion of the third rod 23 that passes through the adjusting member 2a, so that the material of the wireless charging module located on the adjusting member 2a can be avoided and protected.
[0067] The above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. All modifications, equivalent substitutions, improvements, etc. within the spirit and principles of the present application are included in the protection scope of the present application.
