Description

Technical Field

[0001] This utility model relates to the field of vehicle electrical technology, and in particular to a magnetic vehicle electrical appliance. Background Technology

[0002] In related technologies, vehicle electrical appliances include elastic contacts, which cooperate with the vehicle interface to achieve both fixed and electrical connections. This connection method utilizes the elastic deformation of the elastic contacts, which can easily lead to problems such as poor electrical contact and loose connections. Specifically, the vehicle electrical appliance can be a vehicle charger (hereinafter referred to as a car charger), which typically consists of a main body, a positive contact, a negative contact spring, and a PCB board assembly. The negative contact spring is located on the side wall of the car charger, and its fixation relies on the combination of the deformation and rebound force of the negative contact spring and the squeezing and friction forces of the cigarette lighter side wall. This fixing method has two main problems. First, the fixation stability is insufficient. During vehicle operation, due to road bumps and turns, the car charger is prone to shaking inside the cigarette lighter, leading to loose connections or even charging interruptions, affecting the user experience. For devices that require long-term charging, such as navigation systems and dashcams, frequent charging interruptions can interfere with their normal operation. Secondly, it can make insertion difficult. When the rebound force of the negative electrode spring is too great, it becomes difficult to insert the car charger into the cigarette lighter socket, increasing the difficulty of operation and potentially causing wear and tear on the cigarette lighter socket.

[0015] In some embodiments, the first conductive element and the mounting end face are both oriented toward the interface wall in a first direction. The first conductive element is connected to the mounting end face, and the mounting end face and the first conductive element are configured to simultaneously contact the interface wall and enable the first conductive element to acquire electrical energy.

[0016] In some embodiments, the end of the first conductive element along the first direction is coplanar with the mounting end face, and the outer periphery of the second shell has a third groove, with the first conductive element located in the third groove.

[0017] In some embodiments, the mounting end face has a second groove, which is recessed toward the side away from the first housing along a first direction, and the end of the magnetic element located in the second groove along the first direction is coplanar with the mounting end face.

[0018] In some embodiments, the second shell has a cavity, and a magnetic element is located in the cavity. The magnetic element is arranged at a distance from the inner periphery of the second shell along a direction perpendicular to the first direction.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This utility model discloses 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 connected to each other along a first direction. The first shell is adapted to be inserted into a vehicle's in-vehicle interface along the first direction. The maximum size of the second shell is larger than the maximum size of the first shell along a direction perpendicular to the first direction.

Therefore, this utility model's magnetic vehicle electrical appliance, fixed by a magnetic component, is easy to use. Attached Figure Description

[0044] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0047] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0048] In related technologies, car chargers typically consist of a main body, positive contacts, a negative contact spring, and a PCB board assembly. The negative contact spring is located on the side wall of the car charger, and its fixation relies on the combination of the deformation and rebound force of the negative contact spring and the squeezing and friction forces of the cigarette lighter socket side wall. This fixing method has two main problems. First, the fixation stability is insufficient. During vehicle operation, road bumps and turns can cause the car charger to wobble inside the cigarette lighter socket, leading to loose connections or even charging interruptions, affecting the user experience. For devices that require long-term charging, such as navigation systems and dashcams, frequent charging interruptions can interfere with their normal operation. Second, insertion is difficult. When the rebound force of the negative contact spring is too great, inserting the car charger into the cigarette lighter socket becomes difficult, increasing the operational complexity and potentially causing wear and tear on the cigarette lighter socket.

[0049] In view of this, see Figures 1-11This utility model provides a magnetic vehicle electrical appliance 100 for use in vehicles. It should be noted that the magnetic vehicle electrical appliance 100 in this utility model includes various suitable electrical appliances, such as vehicle chargers, vehicle refrigerators, and dashcams. The following description uses an embodiment of the magnetic vehicle electrical appliance 100 as a vehicle charger. Furthermore, the vehicles in this utility model include various types of vehicles, such as private cars and commercial vehicles; vehicles can be gasoline-powered vehicles or new energy vehicles.

[0050] For details, see Figures 1-6 The magnetic vehicle electrical appliance 100 includes a housing 110, a magnetic component 120, and a first conductive component 130. The housing 110 serves as the outer shell of the magnetic vehicle electrical appliance 100. Other components besides the housing 110 can be entirely or partially located within the housing 110. The housing 110 includes a first shell 111 and a second shell 112 connected to each other along a first direction X. The first shell 111 and the second shell 112 can be connected in any suitable manner, and can be detachable (e.g., snap-fit ​​connection, threaded connection, etc.) or integrally connected (e.g., integral molding connection, welding, etc.). The first shell 111 is adapted to be inserted into a vehicle's in-vehicle interface along the first direction X. The in-vehicle interface is located in the vehicle and is used to provide electrical power; specifically, the in-vehicle interface can be a cigarette lighter socket. Along a direction perpendicular to the first direction X, the maximum size of the second shell 112 is larger than the maximum size of the first shell 111, and the end of the second shell 112 connecting to the first shell 111 has a mounting end face 1121. With the above-described dimensional settings, after the first housing 111 is inserted into the vehicle interface, the second housing 112 can abut against the interface wall where the vehicle interface is located, thereby forming the installation positioning of the magnetic vehicle electrical appliance 100 through the aforementioned abutment action. The external structure of the housing 110 can be a rotating body; more specifically, in... Figures 1-6 In the embodiment shown, both the first shell 111 and the second shell 112 are cylindrical. In this case, the mounting end face 1121 is an annular stepped surface formed at the transition position between the first shell 111 and the second shell 112.

[0051] For securing the magnetic vehicle electrical appliance 100, see [link / reference]. Figures 1-6The magnetic component 120 is connected to the second housing 112 so that the second housing 112 can magnetically attract the interface wall where the vehicle interface is located. Specifically, the magnetic component 120 is connected to the mounting end face 1121, and both the magnetic component 120 and the mounting end face 1121 face the interface wall where the vehicle interface is located along the first direction X. The above definition indicates that the magnetic component 120 has at least one magnetic surface for magnetically attracting the interface wall, and the normal of the magnetic surface and the normal of the mounting end face 1121 both point towards the interface wall. This arrangement allows the magnetic component 120 to achieve a better magnetic attraction effect. That is to say, after the magnetic component 120 is provided, while the second housing 112 abuts against the interface wall along the first direction X, the magnetic component 120 and the interface wall generate a magnetic attraction, thereby making the fixing and disassembly of the magnetic vehicle electrical appliance 100 more convenient, and its position more stable and less prone to shaking during use. It should be noted that the fixed connections described in this utility model can be either detachable or integral, and the specific connection method can be changed according to requirements. When the vehicle interface is a cigarette lighter interface, the interface wall itself is made of metal material, so that the magnetic component 120 and the interface wall can generate a magnetic attraction between them, and the interface wall can achieve a contact-type electrical connection to provide power to the magnetic vehicle electrical appliance 100.

[0052] To power the magnetic vehicle electrical appliance 100, see [link / reference]. Figure 1 The first conductive element 130 is connected to the second housing 112. After the mounting end face 1121 contacts the interface wall, the first conductive element 130 is configured to acquire electrical energy. Specifically, in the first method of acquiring electrical energy, the first conductive element 130 directly acquires electrical energy through electrical contact with the interface wall; in the second method, the first conductive element 130 acquires electrical energy through electrical contact between the mounting end face 1121 and the interface wall; in the third method, the first conductive element 130 acquires electrical energy from the interface wall through electrical contact between the magnetic element 120 and the interface wall (which also makes the mounting end face 1121 indirectly contact the interface wall). For the specific electrical connection settings of the first conductive element 130, please refer to the following text.

[0053] It should be noted that the magnetic component 120 and the first conductive component 130 can be two separate components or two parts of the same component. For example, the magnetic vehicle electrical appliance 100 may include a magnetic conductive component, the part of which is used for magnetic attraction is the magnetic component 120, and the part used for generating electrical connection is the first conductive component 130. The embodiments of this application are all described with the case that the magnetic component 120 and the first conductive component 130 are separate components.

[0054] As can be seen, the magnetic vehicle electrical appliance 100 of this utility model includes a housing 110, a magnetic component 120, and a first conductive component 130. The housing 110 includes a first shell 111 and a second shell 112 connected to each other along a first direction X. The first shell 111 is adapted to be inserted into the vehicle's in-vehicle interface along the first direction X. Along a direction perpendicular to the first direction X, the maximum size of the second shell 112 is larger than the maximum size of the first shell 111. The end of the second shell 112 connected to the first shell 111 has a mounting end face 1121. The magnetic component 120 is connected to the mounting end face 1121, and both the magnetic component 120 and the mounting end face 1121 face towards the interface wall where the in-vehicle interface is located along the first direction X. The first conductive component 130 is connected to the second shell 112. After the mounting end face 1121 contacts the interface wall, the first conductive component 130 is configured to acquire electrical energy. Compared to related technologies that rely on the deformation and rebound force of the negative electrode spring and the squeezing and friction forces of the cigarette lighter sidewall for fixation, in this invention, while the second shell 112 abuts against the interface wall along the first direction X, the magnetic component 120 magnetically attracts the interface wall. This makes fixing and disassembling the magnetic vehicle electrical appliance 100 more convenient, and its position is more stable and less prone to shaking during use. Therefore, the magnetic vehicle electrical appliance 100 of this invention, fixed by the magnetic component 120, is easy to use.

[0055] The following describes the more specific settings of magnetic component 120; see [link to documentation]. Figures 1-3 In some embodiments, the end of the magnetic element 120 along the first direction X is coplanar with the mounting end face 1121. Under the above limitations, only a portion of the end of the magnetic element 120 along the first direction X may be coplanar with the mounting end face 1121. This coplanar arrangement ensures that when the second shell 112 abuts against the interface wall, the magnetic element 120 also abuts against the interface wall, thus enabling the magnetic element 120 to exert a better magnetic attraction effect. In other embodiments, the magnetic element 120 protrudes from the mounting end face 1121 along the first direction X, allowing the magnetic element 120 to contact and magnetically connect to the interface wall, and indirectly contacting the mounting end face 1121 with the interface wall.

[0056] See Figures 1-5 The second shell 112 has a cavity 113, and the magnetic element 120 is located in the cavity 113. Along a direction perpendicular to the first direction X, the magnetic element 120 and the inner periphery of the second shell 112 are arranged at a distance. It should be noted that the inner periphery of the second shell 112 refers to the inner periphery of the outer shell portion of the second shell 112, excluding other internal structures of the second shell 112. The aforementioned direction perpendicular to the first direction X includes multiple directions, and the above-mentioned limitation can ensure that the magnetic element 120 and the inner periphery of the second shell 112 are arranged at a distance in multiple directions, or that the arrangement is satisfied in only some of the directions.

[0057] The following describes the first mounting method of magnetic component 120. See [link / reference]. Figures 1-6 In some embodiments, the second shell 112 has a cavity 113, and the mounting end face 1121 has a through hole 1122 communicating with the cavity 113. The magnetic component 120 includes a first magnetic part 121 and a second magnetic part 122 connected to each other along a first direction X. The first magnetic part 121 and the second magnetic part 122 can be connected in any suitable way, and they can be detachably connected or integrally connected. Based on the above definition, in some embodiments, the first magnetic part 121 is located in the cavity 113, and the second magnetic part 122 passes through the through hole 1122 along the first direction X. In conjunction with the description of the foregoing embodiments, the end of the second magnetic part 122 passing through the through hole 1122 can be coplanar with the mounting end face 1121. Through the above arrangement, the second magnetic part 122 can also play a positioning role after passing through the through hole 1122, making the magnetic component 120 easier to install and less prone to shaking.

[0058] Furthermore, to facilitate the installation of the magnetic component 120, the second housing 112 may include a first groove 1124. The first groove 1124 is located on the inner periphery of the second housing 112 and is recessed towards the side closer to the first housing 111. For details, see [link to documentation]. Figures 1-6 In some embodiments, the second shell 112 includes an end wall 1123. Along the first direction X, one side of the end wall 1123 has a mounting end face 1121, and the other side of the end wall 1123 has a first groove 1124 recessed towards the side near the mounting end face 1121. At least a portion of the magnetic element 120 is located in the first groove 1124. It is understood that the first groove 1124 is located in the receiving cavity, and the magnetic element 120 can extend into the first groove 1124 along the first direction X to form a positioning installation. When viewed along the first direction X, the shape and size of the first groove 1124 can be the same as (or substantially the same as) the shape and size of the magnetic element 120 to achieve a better positioning effect for the magnetic element 120. More specifically, in conjunction with the above-described arrangements of the perforation 1122, the first magnetic part 121, and the second magnetic part 122, in some embodiments, when viewed along the first direction X, the outer contour of the first groove 1124 is located outside the outer contour of the perforation 1122. Thus, while the first magnetic part 121 passes through the perforation 1122, the second magnetic part 122 is located in the first groove 1124 and abuts against the bottom surface of the first groove 1124. In addition to accommodating the magnetic component 120, the first groove 1124 can also accommodate other components connected to the magnetic component 120, such as the mounting component 1126 described later.

[0059] The following describes a second mounting method for the magnetic component 120, based on the cavity 113 and the through hole 1122 defined in the aforementioned embodiment. See [link to previous description]. Figures 7-9In some embodiments, one end of the magnetic component 120 along the first direction X is parallel to the mounting end face 1121. When viewed from the direction of the first housing 111 toward the second housing 112, at least a portion of the magnetic component 120 can be exposed through the perforation 1122. Herein, "at least a portion of the magnetic component 120 can be exposed through the perforation 1122 when viewed from the direction of the first housing 111 toward the second housing 112" is defined as: when a user observes from the outside of the magnetic vehicle electrical appliance 100 from the direction of the first housing 111 toward the second housing 112, at least a portion of the magnetic component 120 located within the cavity 113 can be seen through the perforation 1122. The above-described arrangement allows the magnetic component 120 to be placed inside the cavity 113, making the installation of the magnetic component 120 more convenient. Furthermore, the shape design of the magnetic component 120 is less restricted, and a more universally applicable magnetic component 120 can be used. At the same time, the perforation 1122 makes the exterior of the second shell 112 hollowed out, exposing the magnetic component 120 inside the cavity 113, ensuring that the magnetic component 120 can still perform its magnetic function.

[0060] Further, see Figures 6-9 In some embodiments, the second shell 112 includes a shell body 1125 and a mounting member 1126. The mounting member 1126 has a through hole 1122, and the shell body 1125 has a second groove 1127. Specifically, the second groove 1127 may include a first groove portion and a second groove portion. The first groove portion is located on the mounting end face 1121 and is recessed along the first direction X toward the side away from the first shell 111. The second groove portion is located on the outer peripheral side of the shell body 1125 and is recessed along the direction perpendicular to the first direction X toward the side near the cavity 113. The mounting member 1126 is fixedly connected to the shell body 1125 and is located in the second groove 1127. The mounting member 1126 can form the mounting end face 1121 (the mounting end face 1121 may be entirely located on the mounting member 1126, or the mounting end face 1121 may be formed by a portion of the mounting member 1126 and a portion of the shell body 1125). It is understood that the mounting component 1126 has a through hole 1122, allowing it to be used to mount the magnetic component 120. The housing body 1125 is the main part of the second housing 112. The mounting component 1126 and the housing body 1125 can be detachably connected or integrally connected. The structural shape of the mounting component 1126 can be adapted to the structural shape of the housing body 1125. Specifically, in Figures 7-9 In the embodiment shown, the second groove 1127 is located on both the mounting end face 1121 and the outer peripheral side of the shell body 1125. The mounting member 1126 is riveted and fixed in the second groove 1127, and the outer periphery of the mounting member 1126 is flush with both the mounting end face 1121 and the outer peripheral side of the shell body 1125.

[0061] Since the above embodiments divide the second shell 112 into two parts, the shell body 1125 and the mounting member 1126, in some embodiments, the magnetic member 120 can be fixedly connected to the mounting member 1126, and the mounting member 1126 can be provided with corresponding fixing members or limiting members, thus eliminating the need to provide fixing members or limiting members on the shell body 1125, saving manufacturing costs. In addition, in some embodiments, the material of the shell body 1125 can be different from the material of the mounting member 1126, and the material of the shell body 1125 can also be different from the material of the first conductive member 130, which is conducive to further saving manufacturing costs. For example, the materials of the mounting member 1126 and the first conductive member 130 can both be metal materials, while the material of the shell body 1125 can be plastic materials.

[0062] The following describes a third mounting method for the magnetic component 120, based on the second slot 1127 defined in the aforementioned embodiment, see [link to previous description]. Figures 10-11 In some embodiments, the second groove 1127 is located on the outer periphery of the second shell 112 and recessed towards the side away from the first shell 111. The magnetic element 120 is located in the second groove 1127 and its end along the first direction X is coplanar with the mounting end face 1121. With this connection arrangement, the installation operation of the magnetic element 120 to the second shell 112 is more convenient.

[0063] See Figures 1-11 In some embodiments, there are multiple first conductive elements 130 and magnetic elements 120, with a first conductive element 130 positioned between every two magnetic elements 120 along the first direction X. This arrangement ensures good conductivity and magnetic attraction by having multiple first conductive elements 130 and magnetic elements 120 spaced and arranged in a circular pattern. Furthermore, the placement of a first conductive element 130 between every two magnetic elements 120 further ensures good contact and conductivity between the first conductive element 130 and the interface wall. In other embodiments, multiple first conductive elements 130 may be positioned between every two magnetic elements 120.

[0064] The first conductive element 130 can be installed in the same or similar manner as any of the three installation methods for the aforementioned magnetic element 120. More specific details regarding the conductive element's configuration are described below; see [link to documentation]. Figures 1-6 In some embodiments, both the first conductive element 130 and the mounting end face 1121 face the interface wall along the first direction X. After the mounting end face 1121 contacts the interface wall, the first conductive element 130 can contact the interface wall and obtain electrical energy. The above limitation indicates that the first conductive element 130 has at least one contact surface for electrically connecting to the interface wall, and the normal of the contact surface and the normal of the mounting end face 1121 both point towards the interface wall. This arrangement enables the first conductive element 130 to achieve better contact conductivity.

[0065] Further, see Figures 1-3 In some embodiments, the end of the first conductive element 130 along the first direction X is coplanar with the mounting end face 1121. Under the above limitations, only a portion of the end of the first conductive element 130 along the first direction X may be coplanar with the mounting end face 1121. This coplanar arrangement ensures that when the second shell 112 abuts against the interface wall, the first conductive element 130 also abuts against the interface wall, thus enabling the first conductive element 130 to provide better contact conductivity. In conjunction with the aforementioned embodiment regarding the arrangement of the magnetic element 120, when the second shell 112 abuts against the interface wall, the end of the first conductive element 130 along the first direction X is parallel to the end of the magnetic element 120 along the first direction X and abuts against the interface wall together. In other embodiments, the first conductive element 130 protrudes from the mounting end face 1121 along the first direction X, allowing the first conductive element 130 to contact the interface wall and acquire electrical energy, and indirectly contacting the mounting end face 1121 with the interface wall.

[0066] For easier installation of the first conductive element 130, see [link / reference] Figure 6 In some embodiments, the second shell 112 has a third groove 1128 recessed toward the side away from the first shell 111, and at least a portion of the first conductive element 130 is located in the third groove 1128. Specifically, the third groove 1128 may include a third groove portion and a fourth groove portion. The third groove portion is located on the mounting end face 1121 and recessed toward the side away from the first shell 111 along the first direction X, and the fourth groove portion is located on the outer peripheral side of the shell body 1125 and recessed toward the side near the cavity 113 along a direction perpendicular to the first direction X. It is understood that by providing the third groove 1128, after the first conductive element 130 is fixedly installed in the third groove 1128, the end of the first conductive element 130 along the first direction X is coplanar with the mounting end face 1121. The structural shape of the first conductive element 130 can be adapted to the structural shape of the second shell 112. Specifically, in Figure 6 In the illustrated embodiment, the third groove 1128 is located simultaneously on the outer peripheral side of both the mounting end face 1121 and the shell body 1125. The first conductive element 130 is snapped and fixed within the third groove 1128, and the outer periphery of the first conductive element 130 is flush with both the mounting end face 1121 and the outer peripheral side of the shell body 1125. Furthermore, in some embodiments, the structural shape of the first conductive element 130 can refer to the arrangement of the magnetic element 120 in the aforementioned embodiments. For example, the first conductive element 130 may include a first conductive portion and a second conductive portion connected to each other along the first direction X. The arrangement of the first conductive portion and the second conductive portion can refer to the arrangement of the first magnetic portion 121 and the second magnetic portion 122, respectively, and will not be elaborated further here.

[0067] For a more specific conductive configuration of the magnetic vehicle electrical appliance 100, in order to ensure a good and stable conductive effect, the magnetic vehicle electrical appliance 100 may have a positive terminal and a negative terminal, which are electrically connected to the vehicle respectively. See here for further details. Figures 1-11 In some embodiments, the magnetic vehicle electrical appliance 100 further includes a second conductive element 140. The second conductive element 140 is connected to the end of the first housing 111 away from the second housing 112 along the first direction X. After both the first conductive element 130 and the second conductive element 140 acquire electrical energy, the first conductive element 130 is configured as a negative conductive element, and the second conductive element 140 is configured as a positive conductive element. With the above configuration, the first conductive element 130 can serve as the negative terminal of the circuit of the magnetic vehicle electrical appliance 100, and the second conductive element 140 can serve as the positive terminal of the circuit of the magnetic vehicle electrical appliance 100. Specifically, in some embodiments, the second conductive element 140 includes an iron cap and a spring fixedly connected to each other along the first direction X. The iron cap is used to electrically connect to the vehicle interface, and the spring is connected to the end of the first housing 111 along the first direction X, so that the iron cap can achieve elastic expansion and contraction movement along the first direction X.

[0068] See Figures 1-6 In some embodiments, the magnetic vehicle electrical appliance 100 further includes a circuit board 150. The interior of the first shell 111 and the interior of the second shell 112 are connected and together form a cavity 113. The circuit board 150 is located in the cavity 113, and the first conductive element 130 and the second conductive element 140 are electrically connected to the circuit board 150. That is, both the first shell 111 and the second shell 112 can be hollow, allowing the circuit board 150 to pass through the cavity 113, thereby making full use of the internal space of the shell 110 and making the structure of the magnetic vehicle electrical appliance 100 more concise and more integrated. In some embodiments, the end of the second shell 112 away from the first shell 111 along the first direction X can be provided with a charging port. The interface of the circuit board 150 can be exposed from the charging port. After the magnetic vehicle electrical appliance 100 is inserted into the vehicle interface and obtains power, the user can connect the data cable between the charging port and the device to achieve charging.

[0069] Regarding the fixed connection method between the magnetic component 120 and the housing 110, in some embodiments, the magnetic component 120 and the housing 110 are detachably connected. In other embodiments, the magnetic component 120 is configured to be manufactured separately from the second housing 112, and the magnetic component 120 is integrally connected to the second housing 112. Through the above-mentioned integral connection setting, the fixed connection of the magnetic component 120 can be more secure. Specifically, the magnetic component 120 can be integrally connected to the end face of the second housing 112 along the first direction X, that is, it can be connected to any side of the end wall 1123 along the first direction X.

[0070] For easier installation of the magnetic component 120, see [link / reference]. Figures 1-11In some embodiments, the second shell 112 has a groove, which may include one or more of the first groove 1124, the second groove 1127, and the third groove 1128 described in the foregoing embodiments. At least a portion of the magnetic element 120 extends into the groove along the first direction X. The outer contour of the groove may be the same as (or substantially the same as) the outer contour of the magnetic element 120. The size of the groove may be slightly larger than the size of the magnetic element 120. Specifically, in Figures 1-6 In the embodiment shown, the mounting end face 1121 is annular (or can be elliptical). Correspondingly, the outer contour of the groove and the outer contour of the magnetic component 120 are both fan-shaped (the influence of factors such as chamfers and rounded corners needs to be excluded, so they can be roughly fan-shaped). Multiple grooves are distributed around the mounting end face 1121, and the number of magnetic components 120 is the same as the number of grooves and corresponds one-to-one.

[0071] Based on the embodiment where the magnetic component 120 and the second shell 112 are manufactured separately, and the magnetic component 120 is integrally connected to the second shell 112, the specific integral connection method of the magnetic component 120 is described below. Based on the shell body 1125, mounting component 1126, through hole 1122, and second groove 1127 (where the groove body includes the second groove 1127) defined in the aforementioned embodiment, see [link to previous document]. Figures 1-6 In the first integrated connection method of the magnetic component 120, the magnetic component 120 is located in the cavity 113 and integrally connected with the mounting component 1126. This connection arrangement avoids the magnetic component 120 being integrally connected with the shell body 1125, which helps to reduce the operational difficulty of integral connection and save manufacturing costs. At the same time, the mounting component 1126 and the second groove 1127 can be either detachable or integrally connected.

[0072] Based on the perforation 1122, the first magnetic part 121, and the second magnetic part 122 defined in the foregoing embodiments, see [link to previous document]. Figures 7-9 In the second integrated connection method of the magnetic component 120, the first magnetic part 121 is located in the cavity 113 and is integrally connected to the inner circumference of the second shell 112. This connection arrangement makes the connection operation of the magnetic component 120 more convenient and reduces the manufacturing cost. In addition, the second magnetic part 122 can be inserted through the through hole 1122 and does not need to be directly connected to the second shell 112.

[0073] Based on the second slot 1127 defined in the foregoing embodiments, see... Figures 10-11In a third integrated connection method for the magnetic component 120, the magnetic component 120 is integrally connected to the second groove 1127, and its end along the first direction X is coplanar with the mounting end face 1121. With this connection configuration, the operation of connecting the magnetic component 120 to the second housing 112 can be completed on the outside of the second housing 112, making the connection operation more convenient. In other embodiments, the magnetic component 120 may be located in the second groove 1127 and not integrally connected to the second groove 1127 (or the housing 110).

[0074] Furthermore, to facilitate the installation and removal of the magnetic component 120, see [link to relevant documentation]. Figures 10-11 In some embodiments, the second groove 1127 is located on the mounting end face 1121 and is recessed along the first direction X toward the side away from the first housing 111. The first housing 111 has an outer peripheral surface 1111 extending in a direction surrounding the first direction X. The outer peripheral surface 1111 has a fourth groove 1112, which is recessed along a direction perpendicular to the first direction X toward the side near the cavity 113. The end of the fourth groove 1112 near the second housing 112 along the first direction X communicates with the second groove 1127. More specifically, in Figures 10-11 In the illustrated embodiment, the width of the end of the fourth groove 1112 that connects to the second groove 1127 is equal to the width of the end of the second groove 1127 that connects to the fourth groove 1112. Through the cooperation of the second groove 1127 and the fourth groove 1112, on the one hand, it facilitates the installation and removal of the magnetic component 120. Taking installation as an example, the magnetic component 120 can first extend into the fourth groove 1112 from the outside, and then into the second groove 1127 to form a fixed connection, and the fourth groove 1112 can provide the user with a certain operating space; on the other hand, since the fourth groove 1112 and the second groove 1127 form a depth difference at their connection points, the connecting material (such as adhesive, molten material, etc.) required to fix the magnetic component 120 can be retained in this part, so that the connecting material does not protrude from the outer periphery of the housing 110, thus not affecting the normal use of the magnetic vehicle electrical appliance 100.

[0075] Regarding the specific integrated connection method between the magnetic component 120 and the second housing 112, in some embodiments, the magnetic component 120 is configured to be glued to the second housing 112. The aforementioned glue bonding can employ a dispensing fixing process. The shape of the glue dispensing can be straight, curved, circular, dotted, columnar, or planar, etc. Besides the glue bonding described above, integrated connections can also include welding, riveting, fusion welding, and other connection methods.

[0076] It should be noted that the coplanar and parallel relationships defined in this utility model correspond to the ideal state during the design process, and the influence of manufacturing errors and assembly errors needs to be excluded.

[0077] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the application concept of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
