[0003] With the continuous advancement of technology and the public's love for wireless charging technology, some vehicles have also begun to be equipped with on-board wireless charging devices for mobile phones. However, because the wireless charging device should be configured in a position that is convenient for the driver to pick up and put, and the interior decoration of the position that is convenient for the driver to pick up and put is relatively numerous, in the existing technology, there are many on-board wireless charging devices that cannot be adapted to most mobile phones; after investigation, it was found that the reason why most mobile phones cannot be adapted is that there are many types of mobile phones on the market, their shapes and sizes are different, and the positions of the wireless charging coils of mobile phones are also different. At the same time, because the interior of the car is relatively complex, the layout of the wireless charging device is greatly restricted. If the mobile phone is forcibly placed in the charging position, it will often interfere with the car interior.

[0004] Therefore, a technical solution is needed to solve the technical problem that the mobile phone may interfere with the car interior when placed in the wireless charging position. Utility Model Content

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0028] Please also read Figures 1 to 6 The present embodiment provides a magnetic wireless charger, comprising a base 1 and a wireless charging unit 2. A top cover 3 for protecting the wireless charging unit 2 is disposed on the top of the wireless charging unit 2. The wireless charging unit 2 is used to charge a mobile electronic device. The wireless charging unit 2 converts electrical energy into an electromagnetic field for charging the mobile electronic device. The mobile electronic device may be a mobile phone. The wireless charging unit 2 is slidably connected to one side of the base 1.

[0029] The base 1 is provided with a first ferromagnetic part 7, and the wireless charging unit 2 is provided with a second ferromagnetic part 8 that generates a magnetic attraction force with the first ferromagnetic part 7. The number of the first ferromagnetic part 7 and / or the second ferromagnetic part 8 is greater than one, so that the wireless charging unit 2 can be positioned at a plurality of different positions relative to the base 1 through the magnetic attraction between the first ferromagnetic part 7 and the second ferromagnetic part 8. When the wireless charging unit 2 and the base 1 slide relative to each other until the first ferromagnetic part 7 and the second ferromagnetic part 8 are facing each other, the first ferromagnetic part 7 and the second ferromagnetic part 8 are in a relatively stable position environment. In this state, when a slight vibration or external thrust acts on the wireless charging unit 2 and generates a small amount of movement, the magnetic fields of the first ferromagnetic part 7 and the second ferromagnetic part 8 will restore the position of the wireless charging unit 2, thereby achieving a relatively stable position of the wireless charging unit 2.

[0030] When the wireless charging unit 2 needs to be moved, the thrust for pushing the wireless charging unit 2 is increased, and in the process, the magnetic attraction of the first ferromagnetic part 7 and the second ferromagnetic part 8 is overcome until the first ferromagnetic part 7 and the second ferromagnetic part 8 are in a position facing and attracted to each other again between the wireless charging unit 2 and the base 1, and the wireless charging unit 2 is in a relatively stable position again.

[0031] In summary: the base 1 in this embodiment is installed on the interior of the vehicle. When using the wireless charger of this embodiment, the mobile phone can be placed on the wireless charging unit 2 to start charging; the sliding positioning component in this embodiment allows the wireless charging unit 2 to slide relative to the base 1, so that the mobile phone can better cooperate with the wireless charging unit 2 to achieve charging.

[0032] When a certain mobile phone interferes with the vehicle interior when placed on the wireless charging unit 2 due to size issues, the wireless charging unit 2 can be pushed to slide, thereby changing the position of the wireless charging unit 2 relative to the base 1 (that is, relative to the car interior), thereby avoiding the technical problem of interference between the mobile phone and the car interior.

[0033] The magnetic wireless charger further comprises a sliding portion between the base 1 and the wireless charging unit 2, the sliding portion comprising a slide groove 4 opened along a first direction, the slide groove 4 being arranged in one of the base 1 and the wireless charging unit 2, and the other of the base 1 and the wireless charging unit being provided with a slider 5 slidably connected in the slide groove 4. Figure 2 To Attachment Figure 6 In this embodiment, the slider 5 is fixedly connected to the wireless charging unit 2, and the slide groove 4 is provided at the base 1. In other embodiments, the slider 5 is fixed to the base 1, and the slide groove 4 is provided at the wireless charging unit 2.

[0034] The number of the first ferromagnetic member 7 and the second ferromagnetic member 8 is greater than one. Figure 2 , Attachment Figure 3 In this embodiment, six first ferromagnetic parts 7 and six second ferromagnetic parts 8 are provided. The more the number of the above ferromagnetic parts is, the more stable states of magnetic attraction of the two ferromagnetic parts are, that is, the wireless charging unit 2 can stay stably in more positions, which can meet more needs of users.

[0035] The outer wall of the base 1 is provided with a lower magnetic groove 6, the outer wall of the wireless charging unit 2 is provided with an upper magnetic groove 10, the first ferromagnetic component 7 is arranged in the lower magnetic groove 6, the second ferromagnetic component 8 is arranged in the upper magnetic groove 10, the first ferromagnetic component 7 and the second ferromagnetic component 8 are arranged along the first direction, the lower magnetic groove 6 and the upper magnetic groove 10 are mainly used to accommodate the ferromagnetic components, that is, the ferromagnetic components are embedded in the corresponding magnetic grooves to prevent the ferromagnetic components from moving and affecting the sliding stability of the wireless charging unit 2. Furthermore, since the ferromagnetic components are embedded in the magnetic grooves, the surfaces of the wireless charging unit 2 and the base 1 are relatively flat, and the distance between the two can be configured closer. From the external structure of the charger, the gap between the wireless charging unit 2 and the base 1 is smaller, and the overall space utilization rate is higher.

[0036] A plurality of first ferromagnetic parts 7 are arranged at equal distances at a first spacing, and a plurality of second ferromagnetic parts 8 are arranged at equal distances at a second spacing, the ratio of the first spacing to the second spacing is A, and the ratio of the second spacing to the first spacing is B, and A or B is a positive integer. As mentioned above, the positional relationship between the wireless charging unit 2 and the base 1 in the vertical direction is limited by the slider 5 and the slide groove 4, and the positional relationship between the two in the lateral direction (first direction) is limited by the first ferromagnetic part 7 and the second ferromagnetic part 8, and only one relative position of a single first ferromagnetic part 7 and a single second ferromagnetic part 8 is a stable state, and this state is the positional state where the distance between the two is the smallest; the above integer multiple distance relationship makes it possible that: when one of the first ferromagnetic parts 7 and one of the second ferromagnetic parts 8 attract each other and are in a positional relationship with the smallest spacing, there is no other first ferromagnetic part 7 close to one of the second ferromagnetic parts 8 and the two are not in a positional relationship with the smallest spacing, thereby ensuring that the wireless charging unit 2 can be in a relatively stable positional relationship in the first direction, that is, the position of the wireless charging unit 2 is relatively stable.

[0037] A and B are equal to one, see the attached Figure 2 , Attachment Figure 3 In this embodiment, the first ferromagnetic parts 7 are arranged at equal intervals, the second ferromagnetic parts 8 are also arranged at equal intervals, and the distance between every two adjacent first ferromagnetic parts 7 is equal to the distance between any two adjacent second ferromagnetic parts 8, further ensuring that when one of the first ferromagnetic parts 7 and one of the second ferromagnetic parts 8 attract each other and are in a position relationship with the minimum distance, there is no other first ferromagnetic part 7 close to one of the second ferromagnetic parts 8 and the two are not in a position relationship with the minimum distance, that is, further ensuring the position stability of the wireless charging unit 2.

[0038] Reference Figure 4 The base 1 includes a base 101, a control board 102, and a seat cover 103 which are arranged in sequence. The control board 102 is located in the accommodation space surrounded by the base 101 and the seat cover 103. The seat cover 103 is provided with an inner wire groove 9. The wireless charging unit 2 and the control board 102 are commonly connected with a wire, and the wire runs through the inner wire groove 9. The wireless charging unit 2 and the control board 102 cooperate to realize the basic function of wireless charging. The wire running through the inner wire groove 9 is used to supply power to the wireless charging unit 2. The above-mentioned wireless charging unit 2 and the control board 102 are conventional technical means that should be known to those skilled in the art, and will not be described in detail here.

[0039] Reference Figure 4 The base 101 is provided with an external wire groove 104, and the control board 102 is provided with a wire connected to an external power source through the external wire groove 104, so as to conduct the electric energy of the vehicle power supply to the control board 102 of the wireless charging device of this embodiment.

[0040] Reference Figure 5 , Attachment Figure 6, the slide groove 4 is provided in the base 1, and a groove stopper 401 is provided on one side of the slide groove 4 close to the slider 5 along the first direction, and the slider 5 includes a block 501 and a baffle 502 provided on the side of the block 501, and the baffle 502 cooperates with the groove stopper 401 to prevent the slider 5 from being separated from the slide groove 4. As mentioned above, in this embodiment, the slider 5 is fixed to the wireless charging unit 2, and the slide groove 4 is provided in the base 1, and the cooperation between the two enables the wireless charging unit 2 to be slidably connected to the base 1 along the slide groove 4 and cannot be separated from each other; specifically, when the slider 5 is assembled in the slide groove 4, the baffle 502 is located at the lower part of the groove stopper 401. The groove stopper 401 limits the slider 5 to prevent the slider 5 from moving upward and being separated from the base 1.

[0041] It is particularly noted that in the embodiment of the present utility model, the first ferromagnetic component 7 and the second ferromagnetic component 8 are not necessarily both magnetic components. Only one of them needs to be magnetic, and the other component can be attracted by the magnetic force. For example, one of the components is set as a permanent magnet and the other component is set as iron. Furthermore, one of the components is set as an electromagnet and the other component is set as iron. All of the above embodiments should be included in the protection scope of this application.

[0042] It is further explained that: in the above-mentioned embodiment of the present application, the base 1 and the wireless charging unit 2 are in direct contact only through the slider 5 and the slide groove 4, and the friction between the two is easy to control. By only making the matching part of the slider 5 and the slide groove 4 relatively smooth, the friction can be greatly reduced, which can not only improve the user experience when using it, but also increase the service life of the product by effectively reducing wear, and is more economical.
