Description

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 a negative electrode spring extending from the circumferential side wall of the housing to elastically press against the side wall of the vehicle's interface, thus securing them to the interface. This method of securing in-vehicle electrical appliances can easily cause problems such as excessive rebound force resulting from deformation of the negative electrode spring, leading to difficulties in insertion and removal. Utility Model Content

[0003] This utility model provides a magnetic vehicle electrical appliance to solve the problem of difficulty in plugging and unplugging magnetic vehicle electrical appliances.

[0004] This utility model provides a magnetic vehicle electrical appliance for use in a vehicle, comprising: a housing and a first conductive element. 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 the vehicle's in-vehicle interface along the first direction. In 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 mounting end face forms a first hole extending along the first direction. A portion of the first conductive element is accommodated within the second shell, and another portion extends beyond the mounting end face through the first hole. The first conductive element is configured to acquire electrical energy.

[0005] Furthermore, the magnetic vehicle electrical appliance also includes a magnetic component, and both the magnetic component and the mounting end face are oriented towards the interface wall where the vehicle interface is located along the first direction.

[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 adhered to the groove wall of the mounting groove.

[0009] Furthermore, the magnetic vehicle electrical appliance also includes a circuit board housed within the housing. The first conductive element includes a connecting portion and at least one first abutting portion. The connecting portion is housed within the second housing and electrically connected to the circuit board. One end of the first abutting portion is electrically connected to the connecting portion, and the other end extends beyond the mounting end face through the first hole. The first abutting portion is configured to acquire electrical energy and conduct current with the connecting portion.

[0010] Furthermore, the inner wall of the second shell is formed with an insert groove, and the connecting part is embedded in the insert groove.

[0011] Furthermore, the magnetic vehicle electrical appliance also includes a magnetic component, which includes at least one magnetic block. The first abutment portion has two or more of them, and at least one magnetic block is provided between adjacent first abutment portions along the direction surrounding the first shell.

[0012] Furthermore, the magnetic vehicle electrical appliance also includes a second conductive element. A second hole is formed on the end face of the first shell away from the second shell. A portion of the second conductive element is accommodated within the shell and electrically connected to the circuit board. 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 and is configured to acquire electrical energy. The second conductive element, the circuit board, the connecting portion, and the first abutting portion are sequentially electrically connected to form a conductive path. 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.

[0013] 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.

[0014] This utility model provides a magnetic vehicle electrical appliance, including a housing and a first conductive element. The outer peripheral surface of the second shell of the housing is connected to the outer peripheral surface of the first shell through a mounting end face intersecting the first direction, i.e., the mounting end face is a stepped surface between the second shell and the first shell. A first hole is formed on the mounting end face, and part of the first conductive element extends beyond the mounting end face through the first hole, that is, the first conductive element extends out along the axial direction of the housing. This magnetic vehicle electrical appliance eliminates the existing method of the negative electrode spring elastically abutting against the vehicle interface radially, reducing the possibility of insertion and removal difficulties caused by excessive rebound force generated by the deformation of the negative electrode spring. When the magnetic vehicle electrical appliance is inserted into the vehicle interface, and the first direction forms an acute angle with the direction of gravity, there is an interaction force between the mounting end face and the upward stepped surface inside the vehicle interface under the action of gravity, so that the first conductive element can abut against the conductive connector of the vehicle interface relatively stably, thereby improving the stability of the electrical connection.

[0026] Currently, in-vehicle electrical appliances have become an essential accessory for many car owners, providing convenient charging for mobile phones and other electronic devices. Existing in-vehicle electrical appliances rely on a negative electrode spring extending from the circumferential side wall of the housing to press against the side wall of the in-vehicle interface (sometimes called a cigarette lighter socket), thus securing them within the interface. This method of securing in-vehicle electrical appliances is prone to problems such as excessive rebound force caused by deformation of the negative electrode spring, leading to difficulties in insertion and removal.

[0027] Therefore, embodiments of this application provide a magnetic vehicle electrical appliance that is easier and less strenuous to plug in and unplug.

[0028] Below, refer to Figures 1 to 4 Some embodiments of this application will be described in detail.

[0029] Figure 1 Exploded views of magnetic vehicle electrical appliances provided in some embodiments of this application; Figure 2 This application provides structural schematic diagrams of magnetic vehicle electrical appliances according to some embodiments; Figure 3 A cross-sectional structural schematic diagram of a magnetic vehicle electrical appliance provided in some embodiments of 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... Figure 1 and Figure 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... Figure 1 and Figure 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 device includes a housing 1 and a first conductive element 3. The housing 1 includes a first shell 10 and a second shell 11, which are distributed along a first direction X. The first shell 10 is adapted to be inserted into a vehicle's on-board interface along the first direction X. The maximum size of the second shell 11 is larger than the maximum size of the first shell 10 along a direction perpendicular to the first direction X. The end of the second shell 11 that connects to the first shell 10 has a mounting end face 13. The outer peripheral surface of the second shell 11 is connected to the outer peripheral surface of the first shell 10 through the mounting end face 13, which intersects the first direction X. The mounting end face 13 forms a first hole 14 extending along the first direction X. A portion of the first conductive element 3 is accommodated within the second shell 11, and another portion extends beyond the mounting end face 13 through the first hole 14. The first conductive element 3 is configured to acquire electrical energy.

[0032] It should be noted that "the maximum size of the second shell 11 is greater than the maximum size of the first shell 10 along the direction perpendicular to the first direction X" means that the maximum size of the outer contour of the second shell 11 is greater than the maximum size of the outer contour of the first shell 10 along the direction perpendicular to the first direction X. In other words, the maximum size of the outer peripheral surface of the second shell 11 is greater than the maximum size of the outer peripheral surface of the first shell 10 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 10 includes an outer cylindrical surface, and the outer peripheral surface of the second shell 11 is similar to an outer elliptical cylindrical surface. Along the direction perpendicular to the first direction X, the major axis of the outer peripheral surface of the second shell 11 is greater than the diameter of the outer peripheral surface of the first shell 10. At the connection between the first shell 10 and the second shell 11, a mounting end face 13 surrounding the first shell 10 is formed. The mounting end face 13 is the end face of the second shell 11 facing the first shell 10 along the first direction X. The mounting end face 13 is sometimes also called a stepped surface.

[0034] Of course, it is understandable that the outer peripheral surface of the first shell 10 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 11 is not limited to a surface similar to an outer elliptical cylinder, 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] It should be noted that the first conductive element 3 can be either a negative conductive element or a positive conductive element.

[0036] The outer peripheral surface of the second shell 11 of the housing 1 is connected to the outer peripheral surface of the first shell 10 through a mounting end face 13 that intersects with the first direction X. That is, the mounting end face 13 is a stepped surface between the second shell 11 and the first shell 10. The mounting end face 13 has a first hole 14, and part of the first conductive element 3 extends beyond the mounting end face 13 through the first hole 14. In other words, the first conductive element 3 extends along the axial direction of the housing 1. This magnetic vehicle electrical appliance eliminates the existing radial elastic contact method, reducing the possibility of insertion and removal difficulties caused by excessive rebound force generated by the deformation of the negative electrode spring. When the magnetic vehicle electrical appliance is inserted into the vehicle interface, and the first direction X is at an acute angle to the direction of gravity, there is an interaction force between the mounting end face 13 and the upward stepped surface of the vehicle interface under the action of gravity. This allows the first conductive element 3 to abut against the conductive connector of the vehicle interface relatively stably, thereby improving the stability of the electrical connection.

[0037] For example, in any direction perpendicular to the first direction X, the size of the outer peripheral surface of the second shell 11 is larger than the size of the outer peripheral surface of the first shell 10.

[0038] It should be noted that "the size of the outer peripheral surface of the second shell 11 is greater than the size of the outer peripheral surface of the first shell 10 in any direction perpendicular to the first direction X" means that the size of the outer peripheral surface of the second shell 11 is greater than the size of the outer peripheral surface of the first shell 10 in the same direction perpendicular to the first direction X, and this same direction is any direction perpendicular to the first direction X.

[0039] In some embodiments of this application, such as Figure 1 As shown, the first conductive element 3 includes a connecting portion 30 and at least one first abutting portion 31. The connecting portion 30 is housed within the housing 1. One end of the first abutting portion 31 is electrically connected to the connecting portion 30, and the other end extends beyond the mounting end face 13 through a first hole 14. The first abutting portion 31 is configured to acquire electrical energy and conduct current with the connecting portion 30. A circuit board 2 is provided inside the housing 1, and the circuit board 2 is electrically connected to the connecting portion 30 of the first conductive element 3. Thus, after the first abutting portion 31 acquires electrical energy, current can be conducted sequentially between the first abutting portion 31, the connecting portion 30, and the circuit board 2.

[0040] For example, one end of the first abutment portion 31 is mechanically connected to the connecting portion 30, and the other end extends beyond the mounting end face 13 through the first hole 14. The connecting portion 30 is mechanically connected to the circuit board 2.

[0041] In some embodiments of this application, such as Figures 1 to 4 As shown, the inner wall of the second shell 11 has an insert groove 15, and the connecting part 30 is embedded in the insert groove 15.

[0042] For example, the inner wall of the second shell 11 is formed with two slots facing away from the first shell 10 at a position close to the first shell 10. The connecting part 30 is accommodated in the second shell 11, and the two parts of the connecting part 30 are respectively embedded in the two slots 15.

[0043] For example, the connecting part 30 is a plate-shaped structure, the thickness direction of the connecting part 30 is consistent with the first direction X, and one of the two opposite sides of the connecting part 30 along its thickness direction is in contact with the groove wall of the mounting groove 15.

[0044] For example, the portion of the connecting part 30 that is embedded in the mounting groove 15 is in contact with each groove wall of the mounting groove 15.

[0045] Thus, the connecting portion 30 of the first conductive component 3 is embedded in the mounting groove 15, and the groove wall of the mounting groove 15 forms multiple physical limits on the connecting portion 30, reducing structural displacement caused by vehicle shaking and improving component stability.

[0046] For example, in any direction perpendicular to the first direction X, at least a portion of the inner circumferential surface of the second shell 11 has a larger dimension than the inner circumferential surface of the first shell 10.

[0047] It should be noted that "the size of at least a portion of the inner circumferential surface of the second shell 11 is greater than the size of the inner circumferential surface of the first shell 10 in any direction perpendicular to the first direction X" means that the size of at least a portion of the inner circumferential surface of the second shell 11 is greater than the size of the inner circumferential surface of the first shell 10 in the same direction perpendicular to the first direction X, and this same direction is any direction perpendicular to the first direction X.

[0048] For example, such as Figures 1 to 4 As shown, the inner circumferential surface of the first shell 10 includes an inner cylindrical surface, and the inner circumferential surface of the second shell 11 is similar to an inner elliptical cylindrical surface. The minor axis of the inner circumferential surface of the second shell 11 is greater than the diameter of the inner circumferential surface of the first shell 10.

[0049] Of course, it is understandable that the inner circumferential surface of the first shell 10 is not limited to an inner 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 inner circumferential surface of the second shell 11 is not limited to an inner elliptical cylindrical surface, but 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.

[0050] In some embodiments of this application, the first abutting part 31 includes an elastic conductive element, one end of which is connected to the connecting part 30, and the other end extends through the first hole 14, protrudes from the mounting end face 13, and elastically abuts against the conductive connector in the vehicle interface.

[0051] The elastic conductive component has axial elastic expansion and contraction capabilities, which can automatically adapt to the size of the vehicle interface of different models, ensuring good contact with the vehicle interface in different models.

[0052] In some embodiments of this application, such as Figures 1 to 3 As shown, the elastic conductive element can be a spring needle.

[0053] The spring pin has axial elasticity and can automatically adapt to the size of the vehicle interface of different models, ensuring good contact with the vehicle interface in different models. Compared with the traditional spring plate structure, the spring pin has a smaller radial dimension and higher mechanical durability, reducing the probability of deformation caused by repeated insertion and removal.

[0054] In some embodiments of this application, such as Figures 1 to 4 As shown, the magnetic vehicle electrical appliance also includes a magnetic component 4, and both the magnetic component 4 and the mounting end face 13 are oriented towards the interface wall where the vehicle interface is located along the first direction X.

[0055] Both the mounting end face 13 and the magnetic component 4 face 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 13 can directly or indirectly abut against the stepped surface inside the vehicle interface, and the magnetic component 4 can be close to the metal part of the stepped surface inside the vehicle interface, improving the reliability of the magnetic attraction of the magnetic component 4, thereby improving the insertion stability of the magnetic vehicle electrical appliance, effectively resisting the vibration and bumps during vehicle operation, and reducing the possibility of loosening and falling off.

[0056] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the magnetic vehicle electrical appliance also includes a magnetic component 4, which is used to magnetically attract the metal part of the interface wall inside the vehicle interface. A portion of the mounting end face 13 is recessed along the first direction X away from the first housing 10 to form a mounting groove 16, and at least a portion of the magnetic component 4 is accommodated in the mounting groove 16.

[0057] The mounting groove 16 can be an annular groove that continuously surrounds the first shell 10 for a complete circle, 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 groove, etc. The specific shape of the mounting groove 16 is not limited. Correspondingly, the magnetic component 4 can be an annular structure that continuously surrounds the first shell 10 for a complete circle, or it can be a non-annular block, or of course, it can be any shape, as long as it can be installed in the mounting groove 16 on the mounting end face 13.

[0058] The magnetic component 4 is magnetically attracted to the metal part of the vehicle interface, which improves the stability of the connection between the magnetic vehicle electrical appliance and the vehicle interface. A portion of the mounting end face 13 is recessed along the first direction X, away from the first housing 10, to form a mounting groove 16. The magnetic component 4 is placed in the mounting groove 16 so that when the magnetic vehicle electrical appliance is inserted into the vehicle interface and the mounting end face 13 abuts against the stepped surface of the vehicle interface, the magnetic component 4 is close to the metal part of the stepped surface inside the vehicle interface, thereby improving the insertion stability of the magnetic vehicle electrical appliance and reducing the probability of charging interruption. Furthermore, placing the magnetic component 4 in the mounting groove 16 allows it to be limited by the multiple groove walls of the mounting groove 16, improving the installation stability of the magnetic component 4. This, in turn, helps to increase the magnetic attraction strength between the magnetic vehicle electrical appliance and the vehicle interface, improving the stability of the connection.

[0059] In some embodiments of this application, the magnetic component 4 includes at least one magnetic block 40, and the mounting end face 13 is formed with at least one mounting groove 16, wherein at least one magnetic block 40 is mounted in the mounting groove 16.

[0060] In some embodiments of this application, such as Figures 1 to 4 As shown, the magnetic component 4 includes at least two magnetic blocks 40, and the mounting end face 13 is formed with at least two mounting grooves 16 spaced apart along the direction surrounding the first shell 10, and each mounting groove 16 mounts at least one magnetic block 40.

[0061] The magnetic block 40 can be, but is not limited to, a permanent magnet or an electromagnet.

[0062] For example, the number of mounting slots 16 is not equal to the number of magnetic blocks 40; some mounting slots 16 may have one magnetic block 40 installed, while some mounting slots 16 may have two or more magnetic blocks 40 installed.

[0063] For example, the number of mounting slots 16 is equal to the number of magnetic blocks 40, and multiple magnetic blocks 40 are installed in multiple mounting slots 16 in a one-to-one correspondence. The shape of the slot wall of the mounting slot 16 is similar to the shape of the outer surface of the magnetic block 40.

[0064] For example, a portion of the magnetic block 40 is accommodated within the mounting groove 16, while another portion extends from the slot formed in the mounting end face 13 of the mounting groove 16.

[0065] For example, the entire magnetic block 40 is accommodated within the mounting slot 16.

[0066] At least two mounting slots 16 are spaced apart along the direction surrounding the first housing 10, thus the mounting slots 16 are non-annular. The magnetic blocks 40 are also non-annular, which facilitates easier installation of the magnetic blocks 40 into the mounting slots 16. Furthermore, the multiple magnetic blocks 40 are spaced apart circumferentially, forming a uniform adsorption force field, which reduces the problem of misalignment of magnetically attracted vehicle electrical appliances caused by single-point magnetic attraction, and allows the axis of the magnetically attracted 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 magnetically attracted vehicle electrical appliances falling off due to vehicle bumps, and makes plugging and unplugging the magnetically attracted vehicle electrical appliance from the vehicle interface easier and less strenuous. Installing at least one magnetic block 40 in each mounting slot 16 increases the magnetic force and improves the reliability and stability of the magnetic attraction.

[0067] In some embodiments of this application, such as Figures 1 to 3 As shown, the magnetic vehicle electrical appliance also includes a magnetic component 4, which includes at least one magnetic block 40. The first abutment portion 31 is provided with two or more, and at least one magnetic block 40 is provided between adjacent first abutment portions 31 along the direction surrounding the first housing 10.

[0068] For example, there are two first holes 14 and two mounting slots 16. The two first holes 14 and the two mounting slots 16 are alternately arranged along the direction surrounding the first shell 10. That is, there is one mounting slot 16 between adjacent first holes 14, or one first hole 14 between adjacent mounting slots 16. For example, there are two first abutting portions 31. Each first abutting portion 31 extends beyond the mounting end face 13 through a first hole 14. The two first abutting portions 31 and the two mounting slots 16 are alternately arranged along the direction surrounding the first shell 10. That is, there is one mounting slot 16 between adjacent first abutting portions 31, or one first abutting portion 31 between adjacent mounting slots 16.

[0069] The magnetic block 40 is located between adjacent first contact parts 31. The magnetic attraction makes the first contact part 31 more stable in contact with the vehicle interface, reducing the chance of poor contact caused by vehicle bumps, and improving space utilization, which is conducive to the miniaturization of magnetic vehicle electrical appliances.

[0070] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the magnetic block 40 has an arc-shaped structure.

[0071] The arc-shaped structure of the magnetic block 40 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.

[0072] In some embodiments of this application, such as Figure 1 and Figure 2 As shown, the magnetic block 40 is interference-fitted into the mounting groove 16; and / or the magnetic block 40 is bonded to the groove wall of the mounting groove 16.

[0073] For example, by coating the groove wall of the mounting groove 16 with a high-temperature resistant adhesive layer, the positional stability of the magnetic block 40 under vibration environment can be improved, and it also has high-temperature resistance, so that the magnetic vehicle electrical appliances can still be stably connected to the vehicle interface under high-temperature conditions.

[0074] The magnetic block 40 and the mounting slot 16 are assembled using an interference fit, which eliminates the need for additional fasteners, reduces assembly costs, and improves production efficiency. Adhesive bonding also eliminates 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 40 within the mounting slot 16, further enhancing the reliability and stability of the connection between the magnetic vehicle electrical components and the vehicle interface.

[0075] In some embodiments of this application, such as Figures 1 to 4 As shown, the second shell 11 has an opening 17 at the end away from the first shell 10, and the shell 1 also includes a shell cover 101 that closes the opening 17. The first shell 10 and the second shell 11 are formed as an integral structure.

[0076] For example, the housing 1 includes a housing body 100 and a housing cover 101. The housing body 100 includes a first housing 10 and a second housing 11. The housing body 100 and the housing cover 101 close to form a receiving cavity 12. The circuit board 2 is disposed in the receiving cavity 12 and is electrically connected to the first conductive element 3 and the second conductive element 5.

[0077] The cover 101 can be a plate-like structure or a hollow structure with an opening at one end.

[0078] The main body 100 is a one-piece molded structure with high structural strength, good sealing performance, and high production efficiency. The cover 101 seals the opening 17 of the second shell 11, increasing the protective performance of the receiving cavity 12. This improves the dust and water resistance of the magnetic vehicle electrical components. The opening 17 in the second shell 11 facilitates the installation or replacement of internal components, improving production and assembly efficiency.

[0079] In some embodiments of this application, such as Figures 1 to 3As shown, the magnetic vehicle electrical appliance also includes a second conductive element 5. A second hole 18 is formed on the end face of the first shell 10 away from the second shell 11. Part of the second conductive element 5 is accommodated in the shell 1 and electrically connected to the circuit board 2. The other part extends beyond the outer end face of the first shell 10 through the second hole 18. The second conductive element 5 is elastic along the extension direction of the second hole 18. After both the first conductive element 3 and the second conductive element 5 obtain electrical energy, the second conductive element 5, the circuit board 2, the connecting part 30 and the first abutting part 31 are sequentially electrically connected to form a conductive path. The first conductive element 3 is configured as a negative conductive element, and the second conductive element 5 is configured as a positive conductive element.

[0080] For example, the second conductive element 5 is mechanically connected to the circuit board 2.

[0081] Part of the second conductive element 5 extends to the outside through the second hole 18. The second conductive element 5 and the first abutment part 31 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 5 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 5 can make tight contact with the inner wall of the vehicle interface, improving the stability of the electrical connection.

[0082] For example, such as Figures 1 to 3 As shown, the second conductive member 5 includes a conductive elastic member 50 and a second abutting portion 51. The two ends of the conductive elastic member 50 are electrically connected to the circuit board 2 and the second abutting portion 51, respectively. The second abutting portion 51 extends beyond the outer end face of the first shell 10 through the second hole 18. The conductive elastic member 50 is elastic along the extension direction of the second hole 18.

[0083] For example, the extension direction of the second hole 18 is consistent with the first direction X.

[0084] For example, the conductive elastic element 50 includes, but is not limited to, a metal helical spring.

[0085] The conductive elastic element 50 can effectively buffer the continuous vibration of the vehicle and reduce the damage to the components caused by the hard impact of the second contact part 51 on the inner wall of the vehicle interface. The conductive elastic element 50 allows the second conductive element 5 to make close contact with the inner wall of the vehicle interface, thereby improving the stability of the electrical connection.

[0086] For example, such as Figures 1 to 4 As shown, the magnetic vehicle electrical appliance also includes at least one charging interface 6 electrically connected to the circuit board 2, the charging interface 6 being housed in the area of ​​the receiving cavity 12 surrounded by the second shell 11.

[0087] The charging port 6 is located in the second shell 11, which has a larger internal space. This layout is reasonable because placing the charging port 6 in the second shell 11 allows for a smaller internal space in the first shell 10, which is beneficial for miniaturization of the shell 1.

[0088] In some embodiments of this application, there are two or more charging interfaces 6, and at least one charging interface 6 is provided on each of the opposite sides of the circuit board 2.

[0089] For example, there are two charging ports 6, which are respectively located on opposite sides of the circuit board 2.

[0090] For example, the multiple charging ports 6 have the same structure; for instance, all of the multiple charging ports 6 are Type-C interfaces.

[0091] For example, the multiple charging ports 6 have different structures, such as some charging ports 6 being Type-C interfaces and some charging ports 6 being Type-A interfaces.

[0092] In some embodiments of this application, such as Figures 1 to 4 As shown, the circuit board 2 is parallel to the plane formed by the intersection of the first direction X and the second direction Y. The circuit board 2 has a charging interface 6 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 2 is accommodated in the area surrounded by the first shell 10 in the receiving cavity 12, and the other part is accommodated in the area surrounded by the second shell 11. There are two magnetic blocks 40, which are located on opposite sides of the circuit board 2 along the third direction Z. The two spring pins of the first abutment part 31 are located on opposite sides of the circuit board 2 along the third direction Z.

[0093] In some embodiments of this application, the cover 101 is a plate-shaped structure with a socket 111. The charging interface 6 is positioned opposite the socket 111 along the first direction X. The charging interface 6 is exposed through the socket 111, so that the connector of the mobile device can be inserted into the charging interface 6 through the socket 111 to achieve charging.
