Description

Technical Field

[0001] This invention relates to the field of charger technology, and specifically to a charger that uses a wall-mounted AC power outlet and has a mobile phone holder. Background Technology

[0002] Currently available chargers typically connect to the phone via a charging cable, and the phone is then placed horizontally on a table. Wireless chargers, on the other hand, are placed directly on the table, with the back of the phone positioned on top of the charger from top to bottom for wireless charging. However, current wireless chargers cannot be directly positioned on an AC power outlet after being plugged in, and cannot support the phone on the wall for wireless charging. This makes them inconvenient and causes considerable inconvenience to users.

[0003] In view of the above, the inventors propose the following technical solution. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a charger with a mobile phone holder.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A charger with a mobile phone holder includes a first housing and at least one power plug for external power supply. The first housing contains at least one power conversion module, which is also connected to at least one wireless charging module. The first housing has a mobile phone placement surface corresponding to the wireless charging module. The first housing contains two positioning walls, referred to as the first positioning wall and the second positioning wall. Each of the first and second positioning walls has a sliding area and a positioning area. Each positioning area has two or more parallel protrusions. A slit penetrating the first housing is also provided next to the positioning wall. A mobile phone holder with two degrees of freedom is provided, which forms a second housing. The second housing includes a tray, which is placed outside the first housing. A sliding arm extends from each side of the tray, referred to as the first sliding arm and the second sliding arm. Each sliding arm passes through the slit. The first and second sliding arms are inserted into the first housing and are parallel to the first and second positioning walls, respectively. Each sliding arm is also provided with at least one limiting protrusion. When the direction of the mobile phone placement surface is perpendicular to the ground, the first and second sliding arms move towards the mobile phone placement surface, so that the side of the tray is higher than the mobile phone placement surface. At the same time, the limiting protrusions are embedded in the gap between the protrusions, and the two sliding arms enter the positioning area, thereby restricting the freedom of the sliding arms to move up and down. At this time, the tray can support the downward weight of the mobile phone. In order to accommodate larger mobile phones, the tray can be adjusted downward to expand the placement space of the mobile phone. The sliding arms are moved in the opposite direction to the mobile phone placement surface, and the limiting protrusions slide out of the restriction of the protrusions, so that the sliding arms enter the sliding area. The tray can be pulled down, and then the sliding arms are moved towards the mobile phone placement surface again, and the limiting protrusions re-enter the positioning area and are restricted.

[0006] Furthermore, in the above technical solution, the first and second sliding arms of the second housing are respectively provided with a first conductive sheet and a second conductive sheet. The first and second conductive sheets extend along the extension direction of the sliding arms and enter the first housing, and each of their ends is provided with a contact point. The first housing is provided with a third conductive sheet and a fourth conductive sheet, which are parallel to the sliding arms. When the limiting protrusion of the sliding arm is embedded in the gap between the protrusion strips, the contact points contact the third and fourth conductive sheets respectively and establish electrical conductivity.

[0007] Furthermore, in the above technical solution, the wireless charging module includes a wireless charging drive circuit connected to the power conversion module and a wireless transmitting coil connected to the wireless charging drive circuit. The wireless transmitting coil is close to the inner surface of the first housing, and the outer surface of the inner surface of the housing forms the mobile phone placement surface. When the mobile phone is placed on the mobile phone placement surface, the wireless transmitting coil generates magnetic lines of force that pass through the mobile phone placement surface and wirelessly inductively charges the mobile phone.

[0008] Furthermore, in the above technical solution, the tray extends downward to form an accommodating space. One surface of this accommodating space is called the watch placement surface. The inner surface of the watch placement surface is provided with a wireless charging drive circuit and a wireless transmitting coil, respectively called the bracket coil drive circuit and the bracket coil. The bracket coil drive circuit is also connected to a first conductive sheet and a second conductive sheet. The third conductive sheet and the fourth conductive sheet are respectively connected to the power conversion module inside the first housing. When the contacts of the first conductive sheet and the second conductive sheet are in contact with the third conductive sheet and the fourth conductive sheet, respectively, the power from the power conversion module is transmitted to the bracket coil drive circuit via the aforementioned conductive sheets.

[0009] Furthermore, in the above technical solution, the upper surface of the tray is provided with a first strap positioning hole, and the strap of the electronic watch placed on the watch placement surface passes through the first strap positioning hole and is positioned by the first strap positioning hole.

[0010] Furthermore, in the above technical solution, a limiting plate is formed by extending rearward from the lower end of the tray. A second strap positioning hole is provided on the limiting plate. The second strap positioning hole is located below the first strap positioning hole. The strap of the electronic watch is embedded in the second strap positioning hole and positioned by the second strap positioning hole.

[0011] Furthermore, in the above technical solution, a permanent magnet is provided inside the second housing, which is located around the bracket coil. The permanent magnet is used to position and maintain the electronic device to be charged.

[0012] Furthermore, in the above technical solution, the first housing is also provided with a power output interface such as a USB charging interface or an AC power socket.

[0013] Furthermore, in the above technical solution, the power plug can rotate relative to the first housing to adjust the angle.

[0014] Furthermore, in the above technical solution, the sliding area is provided with parallel low-height protrusions, which are located next to the protrusions and are lower in height than the protrusions, allowing the sliding arm to slide.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: 1. In practical use, the present invention allows direct power supply by plugging the power plug into an AC power socket on the wall. At the same time, the entire charger is positioned on the AC power socket. At this time, the mobile phone placement surface on the charger is perpendicular to the ground and serves as the working surface for wireless charging. Then, the mobile phone is placed on the mobile phone holder, which supports the downward weight of the mobile phone to stably support it, so that the back of the mobile phone is stably attached to or close to the mobile phone placement surface, positioning the mobile phone against the wall. Then, the wireless charging module realizes wireless charging of the mobile phone, that is, it realizes positioning the mobile phone against the wall and wirelessly charging the mobile phone, which is more convenient to use.

[0016] 2. For larger phones, to better align the coil on the back of the phone with the phone's placement surface, the position of the phone holder relative to the first housing is adjusted, i.e., the height of the phone holder relative to the phone's placement surface is adjusted to expand the phone's placement space. At this time, the sliding arm is moved in the opposite direction to the phone's placement surface, and the limiting protrusion slides out of the restriction of the protrusion strip, allowing the sliding arm to enter the sliding area. The tray can be pulled down to adjust the height of the phone holder relative to the phone's placement surface, thus expanding the phone's placement space. Then, the sliding arm is moved towards the phone's placement surface again, and the limiting protrusion re-enters the positioning area and is restricted, so that the phone holder is fixed relative to the first housing again. This allows it to support larger phones, ensuring the coil on the back of the phone aligns better with the phone's placement surface, and enabling more stable wireless charging by the wireless charging module, making it more convenient to use.

[0019] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0020] See Figure 1-9 As shown, a charger with a mobile phone holder is provided, which includes a first housing 10 and at least one power plug 11 and a mobile phone holder 2 for external power supply.

[0021] The first housing 10 has at least one power conversion module 12 inside, which is also connected to at least one wireless charging module 120. The first housing 10 has a mobile phone placement surface 13 corresponding to the wireless charging module 120. When the mobile phone is connected to the mobile phone placement surface 13, the wireless charging module 120 can wirelessly charge the mobile phone. The wireless charging technology is a conventional technology.

[0022] The first housing 10 has two positioning walls 14, referred to as the first positioning wall 141 and the second positioning wall 142. Each of the first positioning wall 141 and the second positioning wall 142 has a sliding area 143 and a positioning area 144. The positioning area 144 has two or more parallel protrusions 145. A slit 146 penetrating the first housing 10 is also provided beside the positioning wall 14. The mobile phone holder 2 has two degrees of freedom and is adjustable. The mobile phone holder 2 constitutes the second housing 20, which includes a tray 21. The tray 21 is placed outside the first housing 10. A sliding arm 22 extends from each side of the tray 21, referred to as the first sliding arm 221 and the second sliding arm 222. Each sliding arm 22 passes through the slit 146 into the first housing 10 and engages with the first positioning wall 141 and the second positioning wall 142. The wall 142 is parallel, and each of the sliding arms 22 is provided with at least one limiting protrusion 223. When the direction of the mobile phone placement surface 13 is perpendicular to the ground, the first sliding arm 221 and the second sliding arm 222 move toward the mobile phone placement surface 13, so that the side of the tray 21 is higher than the mobile phone placement surface 13. At the same time, the limiting protrusion 223 is embedded in the gap between the protrusion strip 145 and the two sliding arms 22 are inserted into the positioning area 144, so that the freedom of the up and down movement of the sliding arms 22 is restricted. At this time, the tray 21 can support the downward weight of the mobile phone, that is, the entire mobile phone holder 2 is positioned on the first housing 10, so as to support the mobile phone well and make the back of the mobile phone stably fit or close to the mobile phone placement surface 13, and then the wireless charging module 120 realizes wireless charging of the mobile phone. To accommodate larger phones, the tray 21 can be adjusted downwards to expand the phone placement space. Moving the sliding arm 22 in the opposite direction to the phone placement surface 13 causes the limiting protrusion 223 to slide out of the constraint of the protrusion strip 134, allowing the sliding arm 22 to enter the sliding area 143. This pulls the tray 21 downwards. Then, moving the sliding arm 22 towards the phone placement surface 13 again causes the limiting protrusion 223 to re-enter the positioning area 144 and be restrained. In other words, in practical use, the present invention directly draws power by inserting the power plug 11 into a wall AC power socket. Simultaneously, the entire charger is positioned on the AC power socket. At this time, the phone placement surface 13 on the charger is perpendicular to the ground and serves as the working surface for wireless charging. Then, the phone 41 is placed on the phone holder 2, combined with... Figure 8-9As shown, the tray 21 can support the downward weight of the phone 41 to stably support the phone, ensuring that the back of the phone 41 is stably attached to or close to the phone placement surface 13, thus positioning the phone 41 against the wall. Then, the wireless charging module 120 wirelessly charges the phone 41, making it more convenient to use. For larger phones, to better align the coil on the back of the phone 41 with the phone placement surface 13, the position of the phone holder 2 relative to the first housing 10 is adjusted, i.e., the height of the phone holder 2 relative to the phone placement surface 13 is adjusted to expand the placement space for the phone 41. At this time, the sliding arm 22 is moved towards the phone placement surface 13. 3. Moving in the opposite direction, the limiting protrusion 223 slides out of the restriction of the protrusion strip 134, allowing the sliding arm 22 to enter the sliding area 143, which can pull the tray 21 down to adjust the height of the phone holder 2 relative to the phone placement surface 13, thereby expanding the placement space of the phone 41. Then, the sliding arm 22 is moved towards the phone placement surface 13 again, and the limiting protrusion 223 is restricted again in the positioning area 144, so that the phone holder 2 is fixed relative to the first housing 10 again, so that it can support larger phones, so that the coil on the back of the phone can better correspond to the phone placement surface 13, and the wireless charging module 120 can achieve more stable wireless charging of the phone, making it more convenient to use.

[0023] Combination Figure 2 As shown, the wireless charging module 120 includes a wireless charging drive line 121 connected to the power conversion module 12 and a wireless transmitting coil 122 connected to the wireless charging drive line 121. The wireless transmitting coil 122 is close to an inner surface of the first housing 10. The outer surface of the inner surface of the housing forms the mobile phone placement surface 13. When the mobile phone is placed on the mobile phone placement surface 13, the wireless transmitting coil 122 generates magnetic lines of force that pass through the mobile phone placement surface 13 and wirelessly inductively charges the mobile phone.

[0024] Combination Figure 4-5 As shown, the first sliding arm 221 and the second sliding arm 222 of the second housing 20 are respectively provided with a first conductive sheet 224 and a second conductive sheet 225. The first conductive sheet 224 and the second conductive sheet 225 extend along the extension direction of the sliding arm 22 and enter the first housing 10, and each of their ends is provided with a contact point 226. The first housing 10 is provided with a third conductive sheet 147 and a fourth conductive sheet 148. The third conductive sheet 147 and the fourth conductive sheet 148 are parallel to the sliding arm 22. When the limiting protrusion 223 of the sliding arm 22 is inserted into the gap between the protrusion strips 145, the contact point 226 contacts the third conductive sheet 147 and the fourth conductive sheet 148 respectively and establishes electrical conduction, that is, the first conductive sheet 224 and the second conductive sheet 225 are electrically connected to the third conductive sheet 147 and the fourth conductive sheet 148 respectively.

[0025] Combination Figure 4-7 As shown, the tray 21 extends downward to form an accommodating space 230. One surface of the accommodating space 230 is called the watch placement surface 231. A wireless charging drive circuit and a wireless transmitting coil are provided on the corresponding inner surface of the watch placement surface 231, which are respectively called the bracket coil drive circuit 233 and the bracket coil 232. The bracket coil drive circuit 233 is also connected to the first conductive sheet 224 and the second conductive sheet 225. The third conductive sheet 147 and the fourth conductive sheet 148 are respectively connected to the power conversion module 12 inside the first housing 10. When the contacts of the first conductive sheet 224 and the second conductive sheet 225 are in contact with the third conductive sheet 147 and the fourth conductive sheet 148, the power of the power conversion module 12 is transmitted to the bracket coil drive circuit 233 through the aforementioned conductive sheets, and then the bracket coil drive circuit 233 drives the bracket coil 232 to work, thereby realizing the wireless charging function. In this embodiment, the bracket coil drive circuit 233 works in conjunction with the bracket coil 232 to enable wireless charging of the electronic watch 42.

[0026] Combination Figure 6 As shown, the second housing 20 is provided with a plurality of first positioning posts 201, and the first conductive sheet 224 is provided with a plurality of first positioning holes 227. When the first conductive sheet 224 is installed into the second housing 20, the first positioning holes 227 on the first conductive sheet 224 are fitted onto the first positioning posts 201 to achieve positioning and ensure that the first conductive sheet 224 is stably installed in the second housing 20. Similarly, the second housing 20 is provided with a plurality of second positioning posts 202, and the second conductive sheet 225 is provided with a plurality of second positioning holes 228. When the second conductive sheet 225 is installed into the second housing 20, the second positioning holes 228 on the second conductive sheet 225 are fitted onto the second positioning posts 202 to achieve positioning and ensure that the second conductive sheet 225 is also stably installed in the second housing 20.

[0027] Combination Figure 6 or Figure 7 As shown, a permanent magnet 234 is provided inside the second housing 20. The permanent magnet 234 is located around the bracket coil 232. The permanent magnet 234 is used to position and maintain the position of the electronic device (such as an electronic watch) to be charged. When the electronic watch is placed on the tray 21, the permanent magnet 234 positions and maintains the position of the electronic watch, so that the coil inside the electronic watch corresponds with the bracket coil 232, thereby achieving a more stable wireless charging function.

[0028] In addition, combined Figure 7As shown, the upper surface of the tray 21 is provided with a first strap positioning hole 421. The strap 420 of the electronic watch 42, placed on the watch placement surface 231, passes through the first strap positioning hole 421 and is positioned by the first strap positioning hole 421, so that the electronic watch 42 can be stably positioned on the tray 21 and fit against the watch placement surface 231. This allows the bracket coil drive circuit 233 to work with the bracket coil 232 to achieve wireless charging of the electronic watch 42. In addition, a limiting plate 423 extends rearward from the lower rear side of the tray 21. The limiting plate 423 is provided with a second strap positioning hole 422, which is located below the first strap positioning hole 421. The strap 420 of the electronic watch 42 is inserted into the second strap positioning hole 422 and positioned by the second strap positioning hole 422, so that the electronic watch 42 can be more stably positioned on the tray 21.

[0029] Combined Figure 8 As shown, the first housing 10 is also provided with a power output interface such as a USB charging interface 151 or an AC power socket 152. That is, wired charging can be achieved by connecting a charging cable to the USB charging interface 151 to meet different usage requirements.

[0030] Combination Figure 1 , Figure 7-8 As shown, the power plug 11 can rotate relative to the first housing 10 to adjust the angle, so as to meet different usage requirements. That is, according to different usage environments, the power plug 11 can be rotated relative to the first housing 10 to adjust the angle, so as to be able to be plugged into the AC power socket in different usage environments to draw power.

[0031] In other embodiments, combined with Figure 10 As shown, the sliding area 143 is provided with parallel low-height protrusions 1541. The low-height protrusions 1451 are located next to the protrusions 145 and are lower than the protrusions 145, allowing the sliding arm 22 to slide. That is, the sliding arm 22 can move up and down in the sliding area 143 by passing over the low-height protrusions 1451. The low-height protrusions 1451 can block the sliding arm 22 to form resistance, so that the sliding arm 22 can only pass over the low-height protrusions 1451 by pulling down with force. This prevents the sliding arm 22 from being too loose in the sliding area 143 and sliding freely, so as to achieve the purpose of height adjustment. When the sliding arm 22 passes over the low-height protrusions 1451, it will make a clicking sound, indicating to the user that the height is adjusted, making it more convenient to use.

[0032] In order to allow the sliding arm 22 to pass over the low-height protrusion 1451 more smoothly, the upper and lower surfaces of the low-height protrusion 1451 are provided with arc-shaped surfaces.

[0033] In summary, in practical use, the present invention directly draws power by inserting the power plug 11 into the AC power socket on the wall. Simultaneously, the entire charger is positioned on the AC power socket. At this time, the phone placement surface 13 on the charger is perpendicular to the ground and serves as the working surface for wireless charging. Then, the phone is placed on the phone holder 2, where the tray 21 supports the downward weight of the phone, ensuring stable support and allowing the back of the phone to be stably attached to or close to the phone placement surface 13, thus positioning the phone against the wall. The wireless charging module 120 then performs wireless charging, achieving both wall-mounted phone positioning and wireless charging, making it more convenient to use. For larger phones, to better align the coil on the back of the phone with the phone placement surface 13, the position of the phone holder 2 relative to the first housing 10 is adjusted. The height of the bracket 2 relative to the phone placement surface 13 is adjusted to expand the phone placement space. At this time, the sliding arm 22 is moved in the opposite direction to the phone placement surface 13, and the limiting protrusion 223 slides out of the restriction of the protrusion strip 134, so that the sliding arm 22 enters the sliding area 143. The tray 21 can be pulled down to adjust the height of the phone bracket 2 relative to the phone placement surface 13, thereby expanding the phone placement space. Then, the sliding arm 22 is moved towards the phone placement surface 13 again, and the limiting protrusion 223 is restricted again in the positioning area 144, so that the phone bracket 2 is fixed relative to the first housing 10 again, so that it can support larger phones, so that the coil on the back of the phone can better correspond to the phone placement surface 13, and the wireless charging module 120 can achieve more stable wireless charging of the phone, making it more convenient to use.

[0034] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of the present invention.
