Technical Field
[0001] This utility model relates to the field of vehicle charger technology, and in particular to a magnetic vehicle electrical appliance. Background Technology
[0002] Because in-vehicle electrical appliances are convenient to use and carry, they provide convenience for car owners to charge their vehicles, leading to their increasingly widespread use. Current in-vehicle electrical appliances rely on the rebound force generated by the deformation of the negative electrode spring to press against the side wall of the vehicle's charging port, thus securing them inside. This method of fixing in-vehicle electrical appliances is prone to shaking during vehicle operation, leading to charging interruptions and poor stability. Utility Model Content
[0003] This invention provides a magnetic vehicle electrical appliance to improve insertion stability and reduce the probability of charging interruption.
[0004] This utility model provides a magnetic vehicle electrical appliance, comprising: a housing, a magnetic component, and a first conductive component. The housing includes a first shell and a second shell, which are distributed along a first direction. The first shell is adapted to be inserted into a vehicle interface along the first direction. Along a direction perpendicular to the first direction, the maximum size of the second shell is larger than the maximum size of the first shell. The end of the second shell connected to the first shell has a mounting end face. The outer peripheral surface of the second shell is connected to the outer peripheral surface of the first shell through the mounting end face intersecting the first direction. The magnetic component and the mounting end face both face towards the interface wall where the vehicle interface is located along the first direction. The first conductive component is connected to the first shell and is configured to acquire electrical energy.
[0005] Furthermore, the magnetic vehicle electrical appliance also includes a second conductive element, which is connected to the end of the first shell away from the second shell along the first direction. After both the first conductive element and the second conductive element acquire electrical energy, the first conductive element is configured as a negative conductive element, and the second conductive element is configured as a positive conductive element.
[0006] Furthermore, the magnetic component includes at least one magnetic block, and a portion of the mounting end face is recessed along the first direction toward the side away from the first shell to form at least one mounting groove, wherein at least one of the magnetic blocks is mounted in the mounting groove.
[0007] Furthermore, the magnetic block has an arc-shaped structure.
[0008] Furthermore, the magnetic block is interference-fitted into the mounting groove; and / or the magnetic block is bonded to the groove wall of the mounting groove.
[0009] Furthermore, the second shell has an opening at the end away from the first shell, and the shell also includes a shell cover to close the opening. The first shell and the second shell are formed as an integral structure.
[0010] Furthermore, along a direction perpendicular to the first direction, the maximum dimension of the inner circumferential surface of the second shell is greater than the maximum dimension of the inner circumferential surface of the first shell. The magnetic vehicle electrical appliance also includes a circuit board and at least one charging interface electrically connected to the circuit board. The circuit board is housed within the shell, and the charging interface is housed within the second shell.
[0011] Furthermore, the first shell has a first hole, and the first conductive element includes a spring body and a first abutment connected to the spring body. The spring body is accommodated in the shell and electrically connected to the circuit board. The first abutment extends beyond the outer peripheral surface of the first shell through the first hole, and the spring body is elastic along the extension direction of the first hole.
[0012] Furthermore, a second hole is formed at the end of the first shell away from the second shell along the first direction. A portion of the second conductive element is accommodated within the shell and electrically connected to the circuit board, while another portion extends beyond the outer end face of the first shell through the second hole. The second conductive element is elastic along the extension direction of the second hole.
[0013] Furthermore, the second conductive element includes a conductive elastic element and a second abutment. The two opposite ends of the conductive elastic element are electrically connected to the circuit board and the second abutment, respectively. The conductive elastic element is elastic along the first direction, and the second abutment extends beyond the outer end face of the first shell through the second hole.
[0014] This utility model provides a magnetic vehicle electrical appliance, including a housing, a magnetic component, and a first conductive component. The first housing and a second housing are distributed along a first direction, which is the extension direction of the vehicle interface, i.e., the insertion direction of the housing into the vehicle interface. In a direction perpendicular to the first direction, the maximum size of the second housing is larger than the maximum size of the first housing. The end of the second housing connecting to the first housing forms a mounting end face. The outer peripheral surface of the first housing and the outer peripheral surface of the second housing are connected through the mounting end face. The mounting end face intersects the first direction, i.e., it is a stepped surface. Both the mounting end face and the magnetic component face towards the interface wall where the vehicle interface is located along the first direction. Therefore, when the magnetic vehicle electrical appliance is inserted into the vehicle interface, the mounting end face can directly or indirectly abut against the stepped surface inside the vehicle interface, and the magnetic component can be close to the metal part of the stepped surface inside the vehicle interface, improving the reliability of the magnetic attraction and thus enhancing the insertion stability of the magnetic vehicle electrical appliance. This effectively resists vibration and bumps during vehicle operation and reduces the possibility of loosening and falling off. Attached Figure Description

[0026] Currently, car chargers have become an essential accessory for many car owners, providing convenient charging for mobile phones and other electronic devices. Existing car chargers rely on the rebound force generated by the deformation of the negative electrode spring and the side wall of the car's charging port (sometimes called the cigarette lighter socket) to secure them within the port. This method of fixing car chargers is prone to shaking during vehicle operation, leading to charging interruptions and poor stability.
[0027] Therefore, embodiments of this application provide a magnetic vehicle electrical appliance for improving insertion stability.
[0028] Below, refer to Figures 1 to 4 Some embodiments of this application will be described in detail.
[0029] Figure 1 A schematic diagram of the structure of a magnetic vehicle electrical appliance provided in some embodiments of this application; Figure 2 Exploded views of magnetic vehicle electrical appliances provided in some embodiments of this application; Figure 3 A structural schematic diagram from another perspective of some embodiments of the magnetic vehicle electrical appliance provided in this application; Figure 4 This is a schematic diagram of the hidden cover structure of a magnetic vehicle electrical appliance provided in some embodiments of this application.
[0030] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; here, intersecting each other includes perpendicularly intersecting each other. For ease of understanding of the embodiments of this application, in... Figures 2 to 4In the illustrated embodiments, the first direction, the second direction, and the third direction are given as examples where they intersect each other perpendicularly. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as follows... Figures 2 to 4 As shown by the arrows in the diagram, the direction of arrow X is the first direction, the direction of arrow Y is the second direction, and the direction of arrow Z is the third direction.
[0031] This application provides a magnetic vehicle electrical appliance, such as... Figures 1 to 3 As shown, the magnetic vehicle electrical appliance includes a housing 1, a magnetic component 2, and a first conductive component 5. The housing 1 includes a first shell 101 and a second shell 103, which are distributed along a first direction X. The first shell 101 is adapted to be inserted into the vehicle's in-vehicle interface along the first direction X. In a direction perpendicular to the first direction X, the maximum size of the second shell 103 is larger than the maximum size of the first shell 101. The end of the second shell 103 connected to the first shell 101 has a mounting end face 102. The outer peripheral surface of the second shell 103 is connected to the outer peripheral surface of the first shell 101 through the mounting end face 102 intersecting the first direction X. The magnetic component 2 and the mounting end face 102 are both oriented towards the interface wall where the vehicle interface is located along the first direction X. The first conductive component 5 is connected to the first shell 101 and is configured to acquire electrical energy.
[0032] It should be noted that "the maximum size of the second shell 103 is greater than the maximum size of the first shell 101 along the direction perpendicular to the first direction X" means that the maximum size of the outer contour of the second shell 103 is greater than the maximum size of the outer contour of the first shell 101 along the direction perpendicular to the first direction X. In other words, the maximum size of the outer peripheral surface of the second shell 103 is greater than the maximum size of the outer peripheral surface of the first shell 101 along the direction perpendicular to the first direction X.
[0033] For example, such as Figures 1 to 3 As shown, the outer peripheral surface of the first shell 101 includes an outer cylindrical surface, and the outer peripheral surface of the second shell 103 is similar to an outer elliptical cylindrical surface. The major axis of the outer peripheral surface of the second shell 103 is greater than the diameter of the outer peripheral surface of the first shell 101. A mounting end face 102 surrounding the first shell 101 is formed at the connection between the first shell 101 and the second shell 103. The mounting end face 102 is the end face of the second shell 103 facing the first shell 101 along the first direction X. The mounting end face 102 is sometimes also called a stepped surface.
[0034] Of course, it is understandable that the outer peripheral surface of the first shell 101 is not limited to an outer cylindrical surface, but can also be multiple planes connected end to end in sequence, or multiple irregular curved surfaces connected end to end in sequence, and so on. The outer peripheral surface of the second shell 103 is not limited to a similar outer elliptical cylindrical surface, but can also be an outer cylindrical surface, multiple planes connected end to end in sequence, or multiple irregular curved surfaces connected end to end in sequence, and so on.
[0035] The first shell 101 and the second shell 103 are distributed along the first direction X, which is the extension direction of the vehicle interface, that is, the insertion direction of the shell into the vehicle interface. Along a direction perpendicular to the first direction X, the maximum size of the second shell 103 is larger than the maximum size of the first shell 101. The end of the second shell 103 connected to the first shell 101 forms a mounting end face 102. The outer peripheral surface of the first shell 101 and the outer peripheral surface of the second shell 103 are connected through the mounting end face 102. The mounting end face 102 intersects the first direction X, that is, the mounting end face 102 is a stepped surface. The mounting end face 102 and the magnetic component 2 are both oriented towards the interface wall where the vehicle interface is located along the first direction X. Therefore, when the magnetic vehicle electrical appliance is inserted into the vehicle interface, the mounting end face 102 can directly or indirectly abut against the stepped surface inside the vehicle interface, and the magnetic component 2 can be close to the metal part of the stepped surface inside the vehicle interface, improving the reliability of the magnetic attraction and thus improving the insertion stability of the magnetic vehicle electrical appliance. It can effectively resist the vibration and bumps during vehicle driving and reduce the possibility of loosening and falling off.
[0036] For example, the outer peripheral surface of the second shell 103 is larger than the outer peripheral surface of the first shell 101 in any direction perpendicular to the first direction X.
[0037] It should be noted that "the size of the outer peripheral surface of the second shell 103 is greater than the size of the outer peripheral surface of the first shell 101 in any direction perpendicular to the first direction X" means that the size of the outer peripheral surface of the second shell 103 is greater than the size of the outer peripheral surface of the first shell 101 in the same direction perpendicular to the first direction X, and this same direction is any direction perpendicular to the first direction X.
[0038] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the magnetic vehicle electrical appliance also includes a second conductive element 6. The second conductive element 6 is connected to the end of the first housing 101 away from the second housing 103 along the first direction X. After both the first conductive element 5 and the second conductive element 6 acquire electrical energy, the first conductive element 5 is configured as a negative conductive element, and the second conductive element 6 is configured as a positive conductive element.
[0039] When inserted into the vehicle interface, the second conductive element 6, acting as the positive conductive element, contacts the deepest positive contact inside the vehicle interface, while the first conductive element 5, acting as the negative conductive element, contacts the negative contact on the side wall inside the interface. This fully utilizes the standard electrode layout of the vehicle interface, ensuring that both electrodes reliably contact their corresponding interface contacts, achieving stable power supply.
[0040] In some embodiments of this application, such as Figures 1 to 3 As shown, the magnetic component 2 includes at least one magnetic block 21. A portion of the mounting end face 102 is recessed along the first direction X to the side away from the first shell to form at least one mounting groove 1021, and at least one magnetic block 21 is mounted in the mounting groove 1021.
[0041] The mounting groove 1021 can be an annular groove that continuously surrounds the first shell 101, or it can be an arc-shaped groove (not a complete circle). The annular groove can be a circular ring, a square ring, or an elliptical ring, etc. The specific shape of the mounting groove 1021 is not limited. Correspondingly, the magnetic component 2 can be an annular structure that continuously surrounds the first shell 101, or it can be a non-annular block, or it can be any other shape, as long as it can be installed in the mounting groove 1021 on the mounting end face 102.
[0042] The magnetic component 2 is magnetically attracted to the metal part of the vehicle interface wall, which improves the stability of the connection between the magnetic vehicle electrical appliance and the interface. A portion of the mounting end face 102 is recessed towards the side near the second housing 103 to form a mounting groove 1021. The magnetic component 2 is placed in the mounting groove 1021 of the mounting end face 102, so that when the magnetic vehicle electrical appliance is inserted into the vehicle interface, and the mounting end face 102 abuts against the stepped surface inside the vehicle interface, the magnetic component 2 is close to the metal part of the stepped surface inside the vehicle interface, improving the reliability of the magnetic attraction and thus enhancing the insertion stability of the magnetic vehicle electrical appliance, reducing the probability of charging interruption. Furthermore, placing the magnetic component 2 in the mounting groove 1021 allows it to be limited by the multiple groove walls of the mounting groove 1021, improving the installation stability of the magnetic component 2, thereby increasing the strength of the magnetic attraction between the magnetic vehicle electrical appliance and the vehicle interface, further improving the stability of the connection.
[0043] In some embodiments of this application, such as Figures 1 to 3 As shown, the magnetic component 2 includes at least two magnetic blocks 21. The mounting end face 102 has at least two mounting grooves 1021 that are spaced apart along the direction surrounding the first shell 101 on the side away from the first shell 101 in the first direction X. Each mounting groove 1021 has at least one magnetic block 21 installed.
[0044] At least two mounting slots 1021 are spaced apart along the direction surrounding the first housing 101, thus the mounting slots 1021 are non-annular. The magnetic blocks 21 are also non-annular, which facilitates easier installation of the magnetic blocks 21 into the mounting slots 1021. Furthermore, the multiple magnetic blocks 21 are spaced apart circumferentially, forming a uniform adsorption force field, which reduces the problem of misalignment of magnetic vehicle electrical appliances caused by single-point magnetic attraction, and allows the axis of the magnetic vehicle electrical appliance to be aligned with the center of the vehicle interface. This improves the reliability and stability of the magnetic attraction, reduces the risk of magnetic vehicle electrical appliances falling off due to vehicle bumps, and makes plugging and unplugging the magnetic vehicle electrical appliance from the vehicle interface easier and less strenuous. Installing at least one magnetic block 21 in each mounting slot 1021 increases the magnetic force and improves the reliability and stability of the magnetic attraction.
[0045] For example, the magnetic block 21 can be, but is not limited to, a permanent magnet or an electromagnet.
[0046] For example, the number of mounting slots 1021 is not equal to the number of magnetic blocks 21; some mounting slots 1021 may have one magnetic block 21 installed, while some mounting slots 1021 may have two or more magnetic blocks 21 installed.
[0047] For example, the number of mounting slots 1021 is equal to the number of magnetic blocks 21, and multiple magnetic blocks 21 are installed in multiple mounting slots 1021 in a one-to-one correspondence. The shape of the groove wall of the mounting slot 1021 is similar to the shape of the outer surface of the magnetic block 21.
[0048] For example, part of the magnetic block 21 is accommodated in the mounting groove 1021, and another part extends out from the groove formed in the mounting end face 102 of the mounting groove 1021.
[0049] For example, all of the magnetic blocks 21 are accommodated within the mounting slots 1021.
[0050] In some embodiments of this application, such as Figure 3 As shown, the magnetic block 21 has an arc-shaped structure.
[0051] The arc-shaped structure of the magnetic block 21 is more compatible with the cylindrical inner wall of the vehicle interface, which can increase the uniformity of magnetic attraction, improve the reliability and stability of magnetic attraction, and reduce the possibility of magnetic vehicle electrical appliances separating from the vehicle interface due to sudden braking or bumps of the vehicle.
[0052] In some embodiments of this application, such as Figures 1 to 3 As shown, the magnetic block 21 is interference-fitted into the mounting groove 1021; and / or the magnetic block 21 is bonded to the groove wall of the mounting groove 1021.
[0053] For example, by coating the groove wall of the mounting groove 1021 with a high-temperature resistant adhesive layer, the positional stability of the magnetic block 21 under vibration environment can be improved, and it also has high-temperature resistance, so that the magnetic vehicle electrical appliance can still be stably connected to the vehicle interface under high temperature conditions in summer.
[0054] The magnetic block 21 and the mounting slot 1021 are assembled using an interference fit, which eliminates the need for additional fasteners, reduces assembly costs, and improves production efficiency. Alternatively, adhesive bonding can also eliminate the need for additional fasteners, and the bonding process is simple and convenient, further improving production efficiency. The dual fixing method of adhesive bonding and interference fit increases the stability of the magnetic block 21 within the mounting slot 1021, further enhancing the reliability and stability of the connection between the magnetic vehicle electrical appliance and the vehicle interface.
[0055] In some embodiments of this application, such as Figures 1 to 3 As shown, the second shell 103 has an opening 1031 at the end away from the first shell 101, and the shell 1 also includes a shell cover 11 that closes the opening 1031. The first shell 101 and the second shell 103 are formed as an integral structure.
[0056] For example, the housing 1 includes a housing body 10, which includes a first shell 101 and a second shell 103. The housing cover 11 and the housing body 10 are positioned opposite each other to form a receiving cavity 13, and portions of the first conductive element 5 and the second conductive element 6 are disposed within the receiving cavity 13.
[0057] For example, the cover 11 can be a plate-like structure or a hollow structure with an opening at one end.
[0058] The opening 1031 of the second shell 103 is sealed by the cover 11, increasing the protective performance of the receiving cavity 13. This improves the dustproof and waterproof performance of the magnetic vehicle electrical appliance. The opening 1031 in the second shell 103 facilitates the installation or replacement of internal components of the shell 1, improving production assembly efficiency. Furthermore, the first shell 101 and the second shell 103 are formed as a single molded structure, which has high structural strength, good sealing performance, and high production efficiency.
[0059] In some embodiments of this application, such as Figures 1 to 4 As shown, along the direction perpendicular to the first direction X, the maximum size of the inner circumferential surface of the second shell 103 is greater than the maximum size of the inner circumferential surface of the first shell 101. The magnetic vehicle electrical appliance also includes a circuit board 3 and at least one charging interface 4 electrically connected to the circuit board 3. The circuit board 3 is housed in the shell 1, and the charging interface 4 is housed in the second shell 103.
[0060] For example, such as Figures 2 to 4As shown, the inner circumferential surface of the first shell 101 includes an inner cylindrical surface, and the inner circumferential surface of the second shell 103 is similar to an inner elliptical cylindrical surface. The major axis of the inner circumferential surface of the second shell 103 is greater than the diameter of the inner circumferential surface of the first shell 101. A connecting surface 104 is formed at the connection between the first shell 101 and the second shell 103, surrounding the first shell 101. The connecting surface 104 is the inner end face of the second shell 103 approaching the first shell 101 along the first direction X, and the connecting surface 104 faces the opening 1031 of the second shell 103.
[0061] Of course, it is understandable that the inner circumferential surface of the first shell 101 is not limited to an inner cylindrical surface; it can also be multiple planes connected end to end in sequence, or multiple irregular curved surfaces connected end to end in sequence, and so on. The inner circumferential surface of the second shell 103 is not limited to a surface similar to an inner elliptical cylinder; it can also be an inner cylindrical surface, multiple planes connected end to end in sequence, or multiple irregular curved surfaces connected end to end in sequence, and so on.
[0062] Thus, the inner circumferential surface of the second shell 103 is at least partially larger than that of the inner circumferential surface of the first shell 101, giving the second shell 103 a large internal space, which facilitates the installation of more components and can accommodate large-volume components. It also facilitates the replacement of components and improves maintenance convenience.
[0063] The charging port 4 is located in the second shell 103, which is a reasonable layout. By placing the charging port 4 in the second shell 103, the internal space of the first shell 101 can be set to be smaller, which is conducive to the miniaturization of the shell 1.
[0064] For example, such as Figures 1 to 4 As shown, in any direction perpendicular to the first direction X, the size of at least a portion of the inner circumferential surface of the second shell 103 is larger than the size of the inner circumferential surface of the first shell 101. The magnetic vehicle electrical appliance also includes a circuit board 3 and at least one charging interface 4 electrically connected to the circuit board 3. The circuit board 3 is housed in the shell 1, and the charging interface 4 is housed in the second shell 103.
[0065] It should be noted that "the size of at least a portion of the inner circumferential surface of the second shell 103 is greater than the size of the inner circumferential surface of the first shell 101 in any direction perpendicular to the first direction X" means that in the same direction perpendicular to the first direction X, the size of at least a portion of the inner circumferential surface of the second shell 103 is greater than the maximum size of the inner circumferential surface of the first shell 101, and this same direction is any direction perpendicular to the first direction X.
[0066] In some embodiments of this application, there are two or more charging interfaces 4, and at least one charging interface 4 is provided on each of the opposite sides of the circuit board 3.
[0067] For example, there are two charging ports 4, which are respectively located on opposite sides of the circuit board 3.
[0068] For example, the multiple charging ports 4 have the same structure; for instance, all of the multiple charging ports 4 are Type-C interfaces.
[0069] For example, the multiple charging ports 4 have different structures, such as some charging ports 4 being Type-C interfaces and some charging ports 4 being Type-A interfaces.
[0070] In some embodiments of this application, such as Figure 2 and Figure 4 As shown, the first shell 101 has a first hole 1011. The first conductive element 5 includes a spring body 51 and a first abutment 52 connected to the spring body 51. The spring body 51 is housed in the shell 1 and electrically connected to the circuit board 3. The first abutment 52 extends beyond the outer peripheral surface of the first shell 101 through the first hole 1011. The spring body 51 is elastic along the extension direction of the first hole 1011.
[0071] For example, the first hole 1011 is located at a position of the first shell 101 closer to the second shell 103, that is, the first hole 1011 is closer to the end of the second shell 103 than the end of the first shell 101 that is away from the second shell 103.
[0072] For example, the spring body 51 is an arc-shaped sheet, which is elastic in its bending direction.
[0073] For example, the spring body 51 is housed in the area of the receiving cavity 13 surrounded by the first shell 101. The spring body 51 is a semi-circular piece. Both ends of the spring body 51 are connected to the first abutment 52. The first shell 101 has two first holes 1011 that are radially opposite to each other along the first shell 101. The two first abutments 52 extend from the two first holes 1011 out of the outer peripheral surface of the first shell 101.
[0074] The spring body 51 is connected to the circuit board 3, eliminating the need for wire soldering and improving conductivity reliability and vibration resistance. The spring body 51 elastically deforms along the extension direction of the first hole 1011, and the first abutment 52 extends outward through the first hole 1011, which can adapt to the size of vehicle interfaces of different models, ensuring that the first abutment 52 is in close contact with the inner wall surface of the vehicle interface, thus improving the stability of the electrical connection.
[0075] In some embodiments of this application, such as Figures 1 to 4 As shown, a second hole 1012 is formed at the end of the first shell 101 away from the second shell 103 along the first direction X. A portion of the second conductive member 6 is housed in the shell 1 and electrically connected to the circuit board 3, while the other portion extends beyond the outer end face of the first shell 101 through the second hole 1012. The second conductive member 6 is elastic along the extension direction of the second hole 1012.
[0076] Part of the second conductive element 6 extends to the outside through the second hole 1012. The second conductive element 6 and the first conductive element 5 respectively contact the two poles of the vehicle interface to form a circuit. In this way, the magnetic vehicle electrical appliance has the function of charging mobile devices. The second conductive element 6 can elastically deform along the first direction X to automatically adapt to the size of the vehicle interface of different models, so that the second conductive element 6 can make tight contact with the inner wall surface of the vehicle interface, improving the stability of the electrical connection.
[0077] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the second conductive member 6 includes a conductive elastic member 61 and a second abutment 62. The two ends of the conductive elastic member 61 are electrically connected to the circuit board 3 and the second abutment 62, respectively. The conductive elastic member 61 is elastic along the first direction X. The second abutment 62 extends beyond the outer end face of the first shell 101 through the second hole 1012.
[0078] For example, the extension direction of the second hole 1012 is consistent with the first direction X.
[0079] For example, the conductive elastic element 61 includes, but is not limited to, a metal helical spring.
[0080] The conductive elastic element 61 can effectively buffer the continuous vibration of the vehicle and reduce the damage to the components caused by the hard impact of the second abutment 62 on the inner wall of the vehicle interface. The conductive elastic element 61 enables the second conductive element 6 to make close contact with the inner wall surface of the vehicle interface, thereby improving the stability of the electrical connection.
[0081] In some embodiments of this application, such as Figures 2 to 4 As shown, the circuit board 3 is parallel to the plane formed by the intersection of the first direction X and the second direction Y. The circuit board 3 has a charging interface 4 on each of its opposite sides along the third direction Z. The first direction X, the second direction Y and the third direction Z intersect in pairs. Part of the circuit board 3 is accommodated in the area surrounded by the first shell 101 in the receiving cavity 13, and the other part is accommodated in the area surrounded by the second shell 103. There are two magnetic blocks 21. The two magnetic blocks 21 are located on opposite sides of the circuit board 3 along the third direction Z. The two first abutments 52 of the first conductive member 5 are located on opposite sides of the circuit board 3 along the third direction Z.
[0082] In some embodiments of this application, the cover 11 is a plate-shaped structure with a socket 111. The charging interface 4 is positioned opposite the socket 111 along the first direction X. The charging interface 4 is exposed through the socket 111, so that the connector of the mobile device can be inserted into the charging interface 4 through the socket 111 to achieve charging.
