[0037] The embodiment of the present application provides a magnetic attraction component, which is used to magnetically cooperate with an electronic device 11.

[0038] It is understandable that the magnetic attraction assembly provided in the embodiment of the present application can only support the electronic device after being magnetically engaged with the electronic device 11, or it can also have both the support function and the wireless charging function. The electronic device here can be an Apple mobile phone, etc.

[0039] See also Figures 1 to 5 The magnetic attraction assembly includes a shell 10 and a first magnetic ring 12.

[0040] Specifically, the housing 10 may be the basic structure of the entire magnetic attraction component. After the magnetic attraction component and the electronic device 11 are magnetically matched, the housing 10 may provide structural support for the electronic device 11 .

[0041] The first magnetic ring 12 is disposed in the housing 10 . The first magnetic ring 12 is formed with a first notch 12 a . The first notch 12 a axially penetrates the inner wall surface and the outer wall surface of the first magnetic ring 12 .

[0042] The first magnetic ring 12 is used to be attracted to the second magnetic ring 13 having the second notch 13 a of the electronic device 11 , so as to achieve magnetic attraction and cooperation between the magnetic attraction component and the electronic device 11 .

[0043] Specifically, the second magnetic ring 13 is disposed in the electronic device 11 . The second magnetic ring 13 is formed with a second notch 13 a . The second notch 13 a axially penetrates the inner wall and the outer wall of the second magnetic ring 13 .

[0044] Here, the first magnetic ring 12 and the second magnetic ring 13 refer to the first magnetic ring 12 and the second magnetic ring 13 being annular magnet structures. The first notch 12a axially penetrates the inner and outer wall surfaces of the first magnetic ring 12, which means that the first magnetic ring 12 is disconnected in the circumferential direction, the first magnetic ring 12 is discontinuous in the circumferential direction, and the first notch 12a is formed, and the first magnetic ring 12 is not in a closed loop state. The second magnetic ring 13 axially penetrates the inner and outer wall surfaces of the second magnetic ring 13, which means that the second magnetic ring 13 is disconnected in the circumferential direction, the second magnetic ring 13 is discontinuous in the circumferential direction, and the second notch 13a is formed, and the second magnetic ring 13 is not in a closed loop state.

[0045] Specifically, when the electronic device 11 needs to be placed, the electronic device 11 is brought close to the housing 10. Due to the magnetic attraction between the first magnetic ring 12 and the second magnetic ring 13, the electronic device 11 can be fixed to the housing 10 through the attraction between the first magnetic ring 12 and the second magnetic ring 13, thereby supporting the electronic device 11. When driving, the electronic device 11 can provide clear navigation information; when in a meeting or entertainment activity, it can facilitate video conferencing, presenting materials, or providing a better viewing experience.

[0046] Among them, the shell 10 has a positioning structure, which is used to: when the first magnetic ring 12 and the second magnetic ring 13 are adsorbed, make the projection of one of the first notch 12a and the second notch 13a fall within the projection range of the other in the plane projection perpendicular to the thickness direction of the magnetic attraction component 1.

[0047] It should be noted that the projection of one of the first notch 12a and the second notch 13a falls within the projection range of the other, which means that when the first magnetic ring 12 and the second magnetic ring 13 are adsorbed together, the projection of one of the notches is included in the projection of the other notch. The inclusion here can be complete overlap, or the projection of one of the notches can be smaller than the projection of the other notch.

[0048] Specifically, the positioning structure enables the first magnetic ring 12 and the second magnetic ring 13 to be in a precise position during adsorption, so that the first notch 12a is aligned with the second notch 13a, thereby increasing the adsorption force between the first magnetic ring 12 and the second magnetic ring 13, making the electronic device 11 more stable on the housing 10 and reducing the risk of sliding or falling off.

[0049] It is understandable that in the related art, when the housing and the electronic device are fixed by magnetic attraction, the magnets on the housing and the electronic device are prone to misalignment or weak attraction, which can easily cause the electronic device to shift, rotate, or slide, affecting the placement stability of the electronic device. For example, if the shape of the housing does not match the shape of the electronic device, the attraction between the housing and the electronic device is prone to misalignment; or, if the housing and the electronic device are positioned using square magnets, the square magnets can easily lead to uneven attraction, affecting the stability of the electronic device.

[0050] The magnetic attraction assembly provided in the embodiment of the present application, on the one hand, realizes the adsorption between the housing 10 and the electronic device 11 through the first magnetic ring 12 and the second magnetic ring 13. The magnetic field distribution of the first magnetic ring 12 and the second magnetic ring 13 is uniform, which can provide a more stable adsorption force; on the other hand, the design of the positioning structure can provide a precise alignment mechanism for the first magnetic ring 12 and the second magnetic ring 13, so that when the first magnetic ring 12 is adsorbed with the second magnetic ring 13, the first notch 12a and the second notch 13a are aligned, thereby achieving accurate positioning between the electronic device 11 and the housing 10, reducing the probability of the electronic device 11 being offset, misaligned, or slipping due to external shaking, and the placement stability of the electronic device 11 is high. At the same time, the cooperation of the first notch 12a and the second notch 13a can also reduce the weight of the first magnetic ring 12 and the second magnetic ring 13, facilitate lightweight design, and facilitate heat dissipation. Of course, in the application scenario where the magnetic attraction assembly has a wireless charging function, the first notch 12a and the second notch 13a can also facilitate the transmission of electrical energy between the first magnetic ring 12 and the second magnetic ring 13, thereby increasing the efficiency of electrical energy transmission.

[0051] In some embodiments, when the first magnetic ring 12 and the second magnetic ring 13 are attracted to each other, in a plane projection perpendicular to the thickness direction of the magnetic attraction component, the projection of the first notch 12a and the projection of the second notch 13a completely overlap.

[0052] In other words, the dimensions of the first notch 12a and the second notch 13a are fully compatible, and the shapes and sizes of the first magnetic ring 12 and the second magnetic ring 13 are also fully compatible. In a plane projection perpendicular to the thickness direction of the magnetic attraction component, the circumferential dimension of the first notch 12a is consistent with the circumferential dimension of the second notch 13a.

[0053] In this embodiment, the first notch 12a and the second notch 13a are completely aligned, thereby further increasing the accurate positioning of the first magnetic ring 12 and the second magnetic ring 13, increasing the adsorption force, and improving the placement stability of the electronic device 11. At the same time, in the application scenario where the magnetic attraction component has a wireless charging function, it can also further increase the efficiency of power transmission and reduce magnetic waste.

[0054] For some examples, see Figure 4On the circumference of the outer wall of the first magnetic ring 12, the circumferential width L1 of the first notch 12a is 2 mm (millimeter) to 20 mm, that is, 2 mm ≤ L1 ≤ 20 mm. For example, 2 mm, 4 mm, 6 mm, 8 mm, 9 mm, 11 mm, 12 mm, 13 mm, 15 mm, 17 mm, 19 mm, 20 mm, etc.

[0055] In this embodiment, the size of the first notch 12a can better align the first magnetic ring 12 and the second magnetic ring 13, so that there is sufficient magnetic attraction between the first magnetic ring 12 and the second magnetic ring 13, so that the electronic device 11 and the shell 10 can be stably adsorbed. At the same time, it can also be easily used in wireless charging scenarios.

[0056] Correspondingly, in some embodiments, please refer to Figure 5 On the circumference of the outer wall of the second magnetic ring 13, the width L2 of the second notch 13a along the circumferential direction is 2 mm to 20 mm, that is, 2 mm ≤ L2 ≤ 20 mm. For example, 2 mm, 4 mm, 6 mm, 8 mm, 9 mm, 11 mm, 12 mm, 13 mm, 15 mm, 17 mm, 19 mm, 20 mm, etc.

[0057] In some embodiments, the circumferential width L1 of the first notch 12a on the outer wall of the first magnetic ring 12 is 4 mm to 12 mm, that is, 4 mm ≤ L1 ≤ 12 mm, for example, 4 mm, 5 mm, 6 mm, 7 mm, 7.5 mm, 8 mm, 8.4 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc.

[0058] In this embodiment, the size of the first notch 12a is more reasonable, and the size of the first notch 12a is neither too large nor too small. While ensuring a stable adsorption force between the electronic device 11 and the shell 10, the magnetic attraction component has a higher power transmission efficiency in the wireless application scenario, the first magnetic ring 12 and the second magnetic ring 13.

[0059] Correspondingly, in some embodiments, the width L2 of the second notch 13a along the circumference of the outer wall of the second magnetic ring 13 is 4 mm to 12 mm, that is, 4 mm ≤ L1 ≤ 12 mm. For example, 4 mm, 5 mm, 6 mm, 7 mm, 7.5 mm, 8 mm, 8.4 mm, 9 mm, 10 mm, 11 mm, 12 mm, etc.

[0060] In some embodiments, when the first magnetic ring 12 and the second magnetic ring 13 are adsorbed, in a plane projection perpendicular to the thickness direction of the magnetic attraction component, the angle α between the line L2 connecting the center of the first notch 12a and the center of the circle on which the outer wall surface of the first magnetic ring 12 is located and the first direction is 30° to 60°, that is, 30°≤α≤60°, for example, 30°, 32°, 36°, 38°, 40°, 43°, 45°, 49°, 50°, 54°, 57°, 60°, etc.

[0061] The first direction is parallel to the length direction of the electronic device 11 .

[0062] In this embodiment, the setting of the angle α can roughly position the first notch 12a in the first magnetic ring 12 and at the position corresponding to the electronic device 11. In this way, when the first magnetic ring 12 and the second magnetic ring 13 are adsorbed, the first notch 12a will not be located at the edge of the first magnetic ring 12 closest to the electronic device 11 along the width direction, nor will it be located at the edge area of ​​the first magnetic ring 12 closest to the electronic device 11 along the length direction. The position of the first notch 12a is reasonable, and can ensure a stable adsorption force between the electronic device 11 and the shell 10.

[0063] In some embodiments, the angle α between the line L2 connecting the center of the first notch 12a and the center of the circle on which the outer wall surface of the first magnetic ring 12 is located and the first direction is 38°~52°, that is, 38°≤α≤52°, for example, 38°, 39°, 40°, 41°, 42°, 43°, 44°, 45°, 46°, 47°, 48°, 49°, 50°, 52°, etc.

[0064] In this embodiment, the range of the angle α is more appropriate, which further helps to increase the adsorption reliability between the electronic device 11 and the housing 10 .

[0065] The specific form of the positioning structure is not limited.

[0066] For example, in some embodiments, see Figure 2 The positioning structure includes a first surface 101a, which is a side surface of the shell 10 facing the electronic device 11. In a plane projection perpendicular to the thickness direction of the magnetic component, the first surface 101a is formed into a square.

[0067] That is to say, by setting the surfaces that cooperate with the shell 10 and the electronic device 11, the shape of the first surface 101a is adapted to the shape of the electronic device 11. In this case, the first magnetic ring 12 and the second magnetic ring 13 guide the installation of the shell 10 and the electronic device 11 through the directionality of the square surface to assist in alignment and increase alignment reliability.

[0068] For some examples, see Figure 3 The positioning structure includes a first magnetic member 14, which is arranged in the shell 10. The first magnetic member 14 is used to magnetically cooperate with a second magnetic member 15 arranged on the electronic device 11. The first magnetic member 14 and the second magnetic member 15 are square magnets. The first magnetic member 14 and the second magnetic member 15 are attracted to each other to position the first notch 12a and the second notch 13a.

[0069] It is understood that the first magnetic ring 12 is disposed within the housing 10, and the second magnetic ring 13 is disposed within the electronic device 11, and the first magnetic ring 12 and the second magnetic ring 13 are not in direct contact. The first magnetic member 14 is disposed within the housing 10, and the second magnetic member 15 is disposed within the electronic device 11, and the first magnetic member 14 and the second magnetic member 15 are not in direct contact.

[0070] It is understandable that the first magnetic ring 12 and the first magnetic member 14 are isolated from each other to reduce the probability of magnetic interference between them, and the second magnetic ring 13 and the second magnetic member 15 are isolated from each other to reduce the probability of magnetic interference between them.

[0071] In this embodiment, a first magnetic member 14 and a second magnetic member 15 provided on the electronic device 11 are arranged to be adsorbed and matched, and both are square magnets, which can assist in precise positioning. By aligning the square magnets, the first magnetic ring 12 and the second magnetic ring 13 can be aligned, and the first notch 12a and the second notch 13a can be aligned, thereby increasing the adsorption stability. At the same time, the first magnetic member 14 and the second magnetic member 15 can also further increase the placement stability of the electronic device 11 and reduce the probability of misplacement of the electronic device 11.

[0072] It is understandable that the above two positioning structure embodiments can be combined, that is, in the embodiment where the first surface 101 a is formed in a square shape, the first magnetic member 14 is further provided to assist in precise positioning.

[0073] For some examples, see Figure 2 and Figure 3 The housing 10 includes an upper shell 101 and a lower cover 102. The upper shell 101 is open at one side away from the electronic device 11 in the thickness direction. The lower cover 102 is covered at the open portion of the upper shell 101. The upper shell 101 includes a first surface 101a and a second surface 101b that are opposite to each other. The first surface 101a is used to abut against the electronic device 11. The second surface 101b is provided with an annular groove 101c and a square groove 101d. The square groove 101d is provided on one side of the annular groove 101c along the first direction. The first magnetic ring 12 is provided in the annular groove 101c, and the first magnetic member 14 is provided in the square groove 101d.

[0074] The first direction is parallel to the length direction of the electronic device 11 .

[0075] By arranging the annular groove 101c and the square groove 101d on the second surface 101b opposite to the first surface 101a, when the electronic device 11 is docked with the shell 10, the distance between the first magnetic ring 12 and the second magnetic ring 13 is closer, and the distance between the first magnetic part 14 and the second magnetic part 15 is closer, so that there is a strong adsorption force between the first magnetic ring 12 and the second magnetic ring 13, and there is a strong adsorption force between the first magnetic part 14 and the second magnetic part 15, thereby increasing positioning stability.

[0076] Correspondingly, the second magnetic ring 13 and the second magnetic member 15 may also be arranged on a side surface of the electronic device 11 opposite to the surface that interfaces with the first surface 101 a .

[0077] The square groove 101d is arranged on one side of the ring groove 101c along the first direction. On the one hand, the electronic device 11 and the shell 10 can have sufficient adsorption force along the first direction, increasing the adsorption stability. On the other hand, the outer wall radius of the first magnetic ring 12 can also be larger, increasing the adsorption reliability.

[0078] Here, the first direction is the length direction of the electronic device 11 , and the first direction is perpendicular to the thickness direction.

[0079] For some examples, see Figure 3 The annular groove 101c is provided with at least one limiting wall 1011 along the circumferential direction. The limiting wall 1011 is used to match with the first notch 12a to limit the first magnetic ring 12.

[0080] In this embodiment, the limiting wall 1011 can be provided to locate and limit the installation position of the first magnetic ring 12 in the annular groove 101c, thereby reducing the probability of the first magnetic ring 12 moving in the annular groove 101c and increasing the alignment stability.

[0081] In some embodiments, the magnetic attraction component 1 includes a wireless transmitting module, which is disposed in the shell 10. The wireless transmitting module is used to transmit electromagnetic signals to a wireless receiving module disposed in the electronic device 11 and generate an induced current to wirelessly power the electronic device 11.

[0082] The wireless transmitting module and the wireless receiving module realize wireless connection through electromagnetic induction.

[0083] Exemplarily, the wireless transmitting module includes a transmitting circuit board and a transmitting coil, and the wireless receiving module includes a receiving circuit board and a receiving coil. The transmitting circuit board is electrically connected to the transmitting coil, so that the transmitting coil can transmit electromagnetic signals. The transmitting coil generates a changing magnetic field. The receiving coil generates an induced current through electromagnetic induction and receives the electromagnetic signal from the transmitting coil. The receiving circuit board is electrically connected to the receiving coil, thereby receiving electrical energy and outputting electrical energy to the electronic device 11 to realize wireless power supply.

[0084] In this embodiment, the magnetic component not only has a supporting function but also has a wireless power supply function. When the electronic device 11 is placed on the magnetic component, the electronic device 11 can be directly charged without connecting to a charging port, which is convenient, safe and fast to use. In addition, during the wireless power supply process, the alignment of the first magnetic ring 12 and the second magnetic ring 13 can also quickly and correctly position the wireless transmitting module and the wireless receiving module provided in the electronic device 11, facilitating wireless power supply. At the same time, the first magnetic ring 12 and the second magnetic ring 13 can also increase the magnetic flux of the wireless transmitting module and the wireless receiving module, thereby increasing the efficiency of power transmission.

[0085] In some embodiments, the wireless transmitting module includes a transmitting coil and a transmitting circuit board. The transmitting coil is electrically connected to the transmitting circuit board. The first magnetic ring 12 surrounds the outer circumference of the transmitting coil and is spaced apart from the transmitting coil.

[0086] Correspondingly, the second magnetic ring 13 may surround the outer circumference of the receiving coil and be spaced apart from the receiving coil.

[0087] In other words, the transmitting coil is disposed within the annular space of the first magnetic ring 12. This, on the one hand, increases the compactness of the layout of the magnetic attraction assembly 1. On the other hand, when the first magnetic ring 12 and the second magnetic ring 13 are aligned, the positions of the transmitting coil and the receiving coil are accurately positioned, facilitating wireless transmission. Furthermore, the first magnetic ring 12 and the second magnetic ring 13 assist in power transmission, thereby increasing power transmission efficiency. The spacing between the first magnetic ring 12 and the transmitting coil also reduces the probability of interference between the first magnetic ring 12 and the transmitting coil.

[0088] In some embodiments, the magnetic attraction assembly further includes a battery module, which is disposed in the housing 10 and electrically connected to the transmitting circuit board to provide electrical energy to the transmitting circuit board.

[0089] In this embodiment, a battery module is built into the housing 10, and the battery module provides power to the transmitting circuit board, thereby realizing wireless power supply to the electronic device 11. In this way, when wirelessly powering the electronic device 11, the housing 10 does not need an external power supply, which increases charging convenience.

[0090] Of course, in some embodiments, the housing 10 may also be provided with a charging interface to connect to an external power source, the transmitting circuit board, or the battery module, which is not limited here.

[0091] It is understandable that in the embodiment of the present application, the electronic device 11 can be directly magnetically matched with the housing 10, or can be magnetically matched with the housing 10 through other components.

[0092] In some embodiments, the magnetic attraction assembly includes a protective cover for accommodating the electronic device 11 .

[0093] The magnetic attraction component includes a third magnetic ring, which is arranged in the protective cover. The third magnetic ring is used to adsorb with the first magnetic ring 12 to achieve magnetic attraction and coordination between the protective cover and the electronic device 11 as a whole and the housing 10.

[0094] That is to say, the protective cover is used to protect the electronic device 11 and can also serve as a key component for connecting the electronic device 11 and the magnetic attraction component 1.

[0095] Specifically, the electronic device 11 can be placed in the protective cover first. When magnetic attraction is required, the third magnetic ring and the first magnetic ring 12 cooperate to further increase the cooperation stability of the second magnetic ring 13 and the first magnetic ring 12 on the electronic device 11, thereby increasing the placement stability of the electronic device 11 through the cooperation between the protective cover, the electronic device 11 and the shell 10.

[0096] It is understood that the housing 10 and the protective cover 11 are detachably provided, that is, when the user does not need to place the electronic device 11, the user can only use the protective cover to accommodate the electronic device 11 to protect the electronic device 11. When the electronic device 11 needs to be placed, the housing 10 and the protective cover cooperate to achieve stable placement of the electronic device 11.

[0097] It is understandable that the shape of the protective cover is adapted to the electronic device 11, that is, it is substantially square. The shape, size and position arrangement of the third magnetic ring can be adapted to the first magnetic ring 12, and are not limited here.
