Description

Technical Field

[0001] This application relates to the field of cigarette lighter technology, and more particularly to a fixed bracket, a cigarette lighter assembly, and an energy storage device. Background Technology

[0002] Energy storage power supplies and similar devices typically include a cigarette lighter interface to accommodate 12V DC output or input. In related technologies, the cigarette lighter needs to be first fixed to the plastic panel of the power supply casing, and then electrically connected to the main control circuit board inside the power supply via wiring harnesses or other means. The entire assembly process is cumbersome, and the electrical transmission is unreliable. Utility Model Content

[0003] In view of this, this application provides a fixed bracket, a cigarette lighter assembly, and an energy storage device, which facilitates the assembly of the cigarette lighter and ensures stable electrical transmission of the cigarette lighter.

[0004] One embodiment of this application provides a mounting bracket for securing a cigarette lighter to a circuit board. The mounting bracket has a bracket body and mounting feet. The bracket body is configured to secure the cigarette lighter and is in electrical contact with the first electrode of the cigarette lighter. The mounting feet are fixedly connected to the bracket body. The mounting feet are configured to be secured to the circuit board and are electrically connected to the circuit board. Electrical conductivity exists between the bracket body and the mounting feet to electrically connect the first electrode of the cigarette lighter to the circuit board.

[0005] The bracket body, while fixing the cigarette lighter, also makes contact with it. The bracket body achieves electrical conductivity with the first electrode of the cigarette lighter by contacting it. Simultaneously, the bracket feet, while being fixed to the circuit board, also achieve electrical conductivity with the circuit board. Therefore, the cigarette lighter achieves both mechanical and electrical connection to the circuit board through the fixed bracket, simplifying assembly. Furthermore, the fixed bracket stably secures the cigarette lighter and the circuit board, maintaining a stable electrical connection between them, thus ensuring stable electrical transmission from the cigarette lighter.

[0006] In some embodiments of this application, the fixed bracket further includes a fixed arm. The fixed arm is fixedly connected to the bracket body, and a constraint space is formed between the fixed arm and the bracket body. The constraint space is configured to accommodate at least a portion of the cigarette lighter. The fixed arm is configured to prevent the cigarette lighter from disengaging from the constraint space.

[0007] The fixing arm, together with the main body of the bracket, forms a frame structure that confines the cigarette lighter within a constrained space. This restricts the position of the cigarette lighter, facilitating the fixing of the main body of the bracket and the cigarette lighter. The fixing arm can at least pre-fix the cigarette lighter, making it easier for the fixing bracket to move the cigarette lighter together, reducing the difficulty of assembling the cigarette lighter onto the circuit board along with the fixing bracket.

[0008] In some embodiments of this application, the fixing arm is configured to produce elastic deformation and is configured to apply an elastic force toward the support body to the cigarette lighter.

[0009] The fixing arm presses the cigarette lighter against the main body of the bracket, thus stabilizing the cigarette lighter assembly. Furthermore, the fixing arm, through elastic deformation, presses against the cigarette lighter, automatically and stably securing it, and can adapt to the different shapes of various cigarette lighters.

[0010] In some embodiments of this application, the fixing arm is configured as a hoop structure. The fixing arm is configured to clamp the cigarette lighter to the support body.

[0011] The hoop structure keeps the size of the fixing arm relatively fixed and provides good resistance to deformation, thus enabling the fixing arm to be stably fixed to the outside of the cigarette lighter, reducing the possibility of the cigarette lighter coming off the fixing bracket due to vibration or impact, and improving the stability of fixing the cigarette lighter.

[0012] In some embodiments of this application, the support body includes a first fitting portion and a second fitting portion. The first fitting portion is configured to fit against the peripheral wall of the cigarette lighter. The second fitting portion is configured to fit against the end wall of the cigarette lighter. The first fitting portion and the second fitting portion are fixedly connected and electrically conductive. At least one of the first fitting portion and the second fitting portion is configured to make electrical contact with the first electrode of the cigarette lighter.

[0013] The first and second fitting parts of the bracket body can fit onto different sides of the cigarette lighter, thereby constraining the position of the cigarette lighter in different directions, improving the stability of the cigarette lighter relative to the fixed bracket position, and both the first and second fitting parts can contact the cigarette lighter to conduct electricity, facilitating the electrical connection between the fixed bracket and the first electrode of the cigarette lighter, and improving the adaptability range of the cigarette lighter.

[0014] In some embodiments of this application, the support body further includes a connecting portion. The first fitting portion is connected to the second fitting portion via the connecting portion. The connecting portion is configured to bend and deform under stress.

[0015] By bending the connecting part, the relative positions of the first and second fitting parts can be adjusted, so that the area of ​​the bracket body fitting the cigarette lighter can be increased, thereby improving the stability of fixing the cigarette lighter and improving the stability of the electrical connection of the cigarette lighter.

[0016] In some embodiments of this application, the second mating portion is provided with a recess. The recess is configured to allow the second electrode of the cigarette lighter to be exposed.

[0017] The structure that enables the electrical connection between the second electrode of the cigarette lighter and the circuit board can establish a connection by passing through the recess. By setting the recess, the area of ​​the bracket body that fits against the cigarette lighter can be maximized while facilitating the electrical connection of the second electrode of the cigarette lighter, thereby improving the stability of fixing the cigarette lighter and the stability of the first electrode that is electrically connected to the cigarette lighter.

[0018] In some embodiments of this application, the mounting leg includes a connecting arm and a fixed leg. The connecting arm is connected to the support body and is configured to bend and deform under stress. The fixed leg is fixedly connected to the connecting arm and is configured to be fixed to and electrically connected to the circuit board.

[0019] The mounting feet are designed to facilitate the mounting of the feet to the circuit board. By bending the connecting arm, the relative position of the mounting feet and the main body of the bracket can be adjusted so that the mounting feet can be adapted to different mounting positions on the circuit board.

[0020] In some embodiments of this application, the mounting leg further includes a support foot. The connecting arm is connected via the support foot and the fixed foot. The support foot is configured to abut against the circuit board so that the mounting leg is supported on the circuit board.

[0021] The mounting feet are supported on the circuit board, which facilitates the pre-fixation of the mounting bracket and the circuit board, the fixed connection between the mounting feet and the circuit board, and the fixed connection between the second electrode of the cigarette lighter and the circuit board.

[0022] In some embodiments of this application, the fixing bracket is a one-piece molded structure.

[0023] The fixed bracket has good structural stability, which improves the reliability of the fixed cigarette lighter and the electrical connection of the cigarette lighter, and also helps to reduce the difficulty of manufacturing the fixed bracket and assembling the cigarette lighter.

[0024] One embodiment of this application provides a cigarette lighter assembly. The cigarette lighter assembly includes a circuit board and a cigarette lighter. The cigarette lighter assembly also includes a mounting bracket as described in any of the above embodiments. The cigarette lighter is fixedly connected to the bracket body, and the first electrode of the cigarette lighter is in electrical contact with the bracket body. A mounting foot is fixedly connected to the circuit board, and the mounting foot is electrically connected to the circuit board.

[0025] The mounting bracket not only secures the cigarette lighter to the circuit board but also electrically connects the first electrode of the cigarette lighter to the circuit board, eliminating the need for additional wiring between the cigarette lighter and the circuit board, thus simplifying the assembly process and making assembly easier. Furthermore, the mounting bracket provides stable fixation for both the cigarette lighter and the circuit board, ensuring a stable electrical connection between them and thus guaranteeing stable electrical transmission from the cigarette lighter.

[0026] One embodiment of this application provides an energy storage device. The energy storage device includes a housing and a battery cell. The battery cell is disposed within the housing. The energy storage device also includes a cigarette lighter assembly as described in any of the above embodiments. A circuit board is disposed within the housing. The circuit board and the battery cell are electrically connected.

[0027] The fixed bracket secures the cigarette lighter and enables electrical connection between the cigarette lighter and the circuit board, thus connecting the cigarette lighter and the battery cell. This simplifies the assembly process of the cigarette lighter assembly and improves the stability of the electrical connection. Attached Figure Description

[0042] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0044] As used herein, the term "and / or" includes any and all combinations of one or more of the related listed items.

[0045] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be interpreted as indicating or implying relative importance.

[0046] Energy storage power supplies and similar devices typically include a cigarette lighter interface to accommodate 12V DC output or input. In related technologies, the cigarette lighter needs to be first fixed to the plastic panel of the power supply casing, and then electrically connected to the main control circuit board inside the power supply via wiring harnesses or other means. The entire assembly process is cumbersome, and the electrical transmission is unreliable.

[0047] Embodiments of this application provide a mounting bracket for securing a cigarette lighter to a circuit board. The mounting bracket has a bracket body and mounting feet. The bracket body is configured to secure the cigarette lighter and is in electrical contact with the first electrode of the cigarette lighter. The mounting feet are fixedly connected to the bracket body. The mounting feet are configured to be secured to the circuit board and are electrically connected to the circuit board. Electrical conductivity exists between the bracket body and the mounting feet to electrically connect the first electrode of the cigarette lighter to the circuit board.

[0048] The bracket body, while fixing the cigarette lighter, also makes contact with it. The bracket body achieves electrical conductivity with the first electrode of the cigarette lighter by contacting it. Simultaneously, the bracket feet, while being fixed to the circuit board, also achieve electrical conductivity with the circuit board. Therefore, the cigarette lighter achieves both mechanical and electrical connection to the circuit board through the fixed bracket, simplifying assembly. Furthermore, the fixed bracket stably secures the cigarette lighter and the circuit board, maintaining a stable electrical connection between them, thus ensuring stable electrical transmission from the cigarette lighter.

[0049] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0050] See Figures 1 to 3 One embodiment of this application provides a mounting bracket 100, a cigarette lighter assembly 200, and an energy storage device 300. The cigarette lighter assembly 200 is assembled in the energy storage device 300 to provide a DC input or output of 12V, 24V, or 48V, etc. The mounting bracket 100 is used to fix the cigarette lighter 202 of the cigarette lighter assembly 200.

[0051] See Figure 1 In some embodiments, the energy storage device 300 has the functions of storing and discharging electricity for use as backup power for homes, production units, outdoor work, and outdoor recreation.

[0052] See Figure 1 and Figure 2 In some embodiments, the energy storage device 300 includes a housing 301 and a battery cell 302. The battery cell 302 is disposed within the housing 301.

[0053] In some embodiments, the energy storage device 300 further includes a power conversion module (not shown). The power conversion module is electrically connected to the battery cell 302 and is used to control the AC / DC conversion of the output current of the battery cell 302. The energy storage device 300 equipped with the power conversion module can be a small portable power supply, a residential energy storage power supply, an industrial or commercial energy storage power supply, or a containerized energy storage power supply, etc.

[0054] In some embodiments, the power conversion module may be omitted. An energy storage device 300 without a power conversion module can be used independently. An energy storage device 300 without a power conversion module typically only outputs DC power. When used independently, an energy storage device 300 without a power conversion module can be used in conjunction with an energy storage device 300 with a power conversion module as a power system providing additional battery capacity.

[0055] In some embodiments, the energy storage device 300 further includes a cigarette lighter assembly 200. The cigarette lighter assembly 200 includes a circuit board 201 and a cigarette lighter 202. The circuit board 201 is electrically connected to the battery cell 302, and the cigarette lighter 202 is electrically connected to the circuit board 201, so that the cigarette lighter 202 provides a DC input or output of 12V, 24V, or 48V, etc.

[0056] See Figure 3 and Figure 4 In some embodiments, the cigarette lighter 202 includes a cigarette lighter socket 2021 and a cigarette lighter connector (not shown). The cigarette lighter socket 2021 is configured to be electrically connected to the circuit board 201, and the cigarette lighter connector is inserted into the cigarette lighter socket 2021. In other embodiments, the cigarette lighter connector may be omitted, and the cigarette lighter socket 2021 may be connected to other external devices.

[0057] In some embodiments, the cigarette lighter 202 has a first electrode and a second electrode, the first electrode and the second electrode having opposite polarities, and the first electrode and the second electrode are respectively electrically connected to the circuit board 201 to electrically connect the cigarette lighter 202 and the circuit board 201. For example, the first electrode can be a negative electrode and the second electrode can be a positive electrode.

[0058] Understandably, in some embodiments, the cigarette lighter 202 is approximately cylindrical. The first and second electrodes of the cigarette lighter 202 are located on the outer surface of the cigarette lighter 202 to facilitate electrical connection with other components. Specifically, the first electrode is located on the peripheral wall and / or end wall of the cigarette lighter 202, and the second electrode is located on the end wall of the cigarette lighter 202. For the end wall of the cigarette lighter 202, the second electrode is centrally located; if the end wall of the cigarette lighter 202 has a first electrode, the first electrode is arranged around the outer periphery of the second electrode.

[0059] See Figure 4 and Figure 5 In some embodiments, the cigarette lighter 202 further includes a conductive bolt 2022. The conductive bolt 2022 is fixed to the cigarette lighter socket 2021. The conductive bolt 2022 is configured to be electrically connected to the circuit board 201. The electrodes connected to the conductive bolt 2022 and the cigarette lighter socket 2021 have opposite polarities. The cigarette lighter socket 2021 serves as the connection point for the first electrode of the cigarette lighter 202, and the conductive bolt 2022 serves as the connection point for the second electrode of the cigarette lighter 202. The conductive bolt 2022 is located at the end of the cigarette lighter socket 2021, with a portion of its structure extending into the interior of the cigarette lighter socket 2021 and a portion extending outwards.

[0060] See Figure 6 and Figure 7In some embodiments, the cigarette lighter 202 further includes a separator 2023. The separator 2023 is made of an insulating material. The separator 2023 is disposed between the cigarette lighter socket 2021 and the conductive bolt 2022 to prevent the cigarette lighter socket 2021 and the conductive bolt 2022 from directly contacting and short-circuiting.

[0061] See Figure 2 , Figure 4 and Figure 8 In some embodiments, the cigarette lighter assembly 200 further includes a mounting bracket 100. The mounting bracket 100 is used to fix the cigarette lighter 202 to the circuit board 201, so as to facilitate the fixed assembly of the cigarette lighter 202 into the housing 301, and to facilitate the positioning of the relative positions of the cigarette lighter 202 and the circuit board 201, so as to facilitate the electrical connection between the cigarette lighter 202 and the circuit board 201.

[0062] In some embodiments, the fixing bracket 100 is fixedly connected to the cigarette lighter 202 and makes electrical contact with the first electrode of the cigarette lighter 202. The fixing bracket 100 is a conductive structure and is fixedly disposed on the circuit board 201 to be electrically connected to the circuit board 201. The fixing bracket 100 passes through and is soldered to the circuit board 201 to simultaneously achieve electrical connection with the circuit board 201.

[0063] See Figure 4 , Figure 5 and Figure 8 In some embodiments, the mounting bracket 100 has a bracket body 10 and mounting feet 20. The bracket body 10 is configured to be fixedly disposed relative to the fixed cigarette lighter 202 and to be in electrical contact with the first electrode of the cigarette lighter 202. The mounting feet 20 are fixedly connected to the bracket body 10. The mounting feet 20 are configured to be fixed to the circuit board 201 and to be electrically connected to the circuit board 201. There is electrical conductivity between the bracket body 10 and the mounting feet 20, so that the first electrode of the cigarette lighter 202 is electrically connected to the circuit board 201. The mounting feet 20 pass through and are soldered to the circuit board 201 to simultaneously achieve electrical connection with the circuit board 201.

[0064] The main body 10 of the fixing bracket 100, while fixing the cigarette lighter 202, also makes contact with the cigarette lighter 202, and electrical connection is achieved with the first electrode of the cigarette lighter 202 by contacting it. At the same time, the mounting feet 20 of the fixing bracket 100, while being fixed to the circuit board 201, can also make electrical connection with the circuit board 201. Therefore, while the cigarette lighter 202 is mechanically connected to the circuit board 201 through the fixing bracket 100, an electrical connection between the cigarette lighter 202 and the circuit board 201 can also be achieved, eliminating the need for additional wiring between the cigarette lighter 202 and the circuit board 201, simplifying the assembly process and making assembly easier. Furthermore, the fixing bracket 100 can stably fix the cigarette lighter 202 and the circuit board 201, thus maintaining a stable electrical connection between the cigarette lighter 202 and the circuit board 201, thereby ensuring stable electrical transmission of the cigarette lighter 202.

[0065] See Figures 6 to 8 In some embodiments, the first electrode of the cigarette lighter 202 is disposed on the peripheral wall and / or end wall of the cigarette lighter 202. The support body 10 includes a first fitting portion 11 and a second fitting portion 12. The first fitting portion 11 is configured to fit against the peripheral wall of the cigarette lighter 202. The second fitting portion 12 is configured to fit against the end wall of the cigarette lighter 202. The first fitting portion 11 and the second fitting portion 12 are fixedly connected and electrically conductive. At least one of the first fitting portion 11 and the second fitting portion 12 is configured to make electrical contact with the first electrode of the cigarette lighter 202.

[0066] The first fitting part 11 and the second fitting part 12 of the bracket body 10 can fit onto different sides of the cigarette lighter 202, thereby constraining the position of the cigarette lighter 202 in different directions, improving the stability of the position of the cigarette lighter 202 relative to the fixed bracket 100, and both the first fitting part 11 and the second fitting part 12 can contact the cigarette lighter 202 and conduct electricity, which facilitates the electrical connection between the first electrode of the fixed bracket 100 and the cigarette lighter 202, and improves the compatibility range of the cigarette lighter 202.

[0067] See Figure 4 , Figure 7 and Figure 8 In some embodiments, the second electrode of the cigarette lighter 202 is disposed on the end wall of the cigarette lighter 202. The second fitting portion 12 is provided with a recess 121. The recess 121 is configured to allow the second electrode of the cigarette lighter 202 to be exposed.

[0068] The structure that enables the electrical connection between the second electrode of the cigarette lighter 202 and the circuit board 201 can establish a connection by passing through the recess 121. By providing the recess 121, the area of ​​the bracket body 10 that fits against the cigarette lighter 202 can be maximized while facilitating the electrical connection of the second electrode of the cigarette lighter 202, thereby improving the stability of fixing the cigarette lighter 202 and the stability of the first electrode of the cigarette lighter 202.

[0069] It is understood that in some embodiments, the first fitting portion 11 and the second fitting portion 12 are contoured structures that resemble the shape of the outer surface of the cigarette lighter 202, so as to increase the area of ​​fitting with the cigarette lighter 202 and improve the stability of the mechanical and electrical connections.

[0070] In some embodiments, the support body 10 further includes a connecting portion 13. The first fitting portion 11 is connected via the connecting portion 13 and the second fitting portion 12. The connecting portion 13 is configured to bend and deform under stress. The bending deformation of the connecting portion 13 may occur inside the connecting portion 13, at the connection between the connecting portion 13 and the first fitting portion 11, or at the connection between the connecting portion 13 and the second fitting portion 12.

[0071] By bending the connecting part 13, the relative positions of the first fitting part 11 and the second fitting part 12 can be adjusted so that the area of ​​the bracket body 10 fitting the cigarette lighter 202 can be increased, thereby improving the stability of fixing the cigarette lighter 202 and improving the stability of electrically connecting the cigarette lighter 202.

[0072] In some embodiments, the mounting leg 20 includes a connecting arm 21 and a fixing leg 22. The connecting arm 21 is connected to the support body 10 and is configured to bend and deform under stress. The fixing leg 22 is fixedly connected to the connecting arm 21 and is configured to be fixed to and electrically connected to the circuit board 201. The bending deformation of the connecting arm 21 can occur inside the connecting arm 21, at the connection between the connecting arm 21 and the support body 10, or at the connection between the connecting arm 21 and the fixing leg 22.

[0073] The fixed foot 22 is provided to facilitate the assembly of the support foot 20 to the circuit board 201. By bending the connecting arm 21, the relative position of the fixed foot 22 and the support body 10 can be adjusted so that the fixed foot 22 can adapt to different fixing positions on the circuit board 201.

[0074] See Figure 3 , Figure 4 and Figure 8 In some embodiments, the mounting leg 20 further includes a support leg 23. The connecting arm 21 is connected to the fixed leg 22 via the support leg 23. The support leg 23 is configured to abut against the circuit board 201 so that the mounting leg 20 is supported on the circuit board 201. The connection between the connecting arm 21 and the support leg 23 may be bent, and the connection between the support leg 23 and the fixed leg 22 may also be bent.

[0075] The mounting bracket 20 is supported on the circuit board 201 by the support foot 23, which facilitates the pre-fixation of the fixing bracket 100 and the circuit board 201, facilitates the fixed connection of the fixing foot 22 and the circuit board 201, and facilitates the fixed connection of the second electrode of the cigarette lighter 202 and the circuit board 201.

[0076] In some embodiments, the mounting feet 20 are connected to the first mating part 11 so that the peripheral wall of the cigarette lighter 202 faces the circuit board 201, reducing the height of the cigarette lighter 202 protruding from the circuit board 201 and facilitating the planning of the position of the cigarette lighter 202.

[0077] See Figure 3 , Figure 6 and Figure 8 In some embodiments, the fixed bracket 100 further includes a fixed arm 30. The fixed arm 30 is fixedly connected to the bracket body 10, and a constraint space 40 is formed between the fixed arm 30 and the bracket body 10. The constraint space 40 is configured to accommodate at least a portion of the cigarette lighter 202. The fixed arm 30 is configured to prevent the cigarette lighter 202 from disengaging from the constraint space 40.

[0078] The fixing arm 30, together with the bracket body 10, forms a frame structure that encloses the cigarette lighter 202 within the constraint space 40, thus restricting the position of the cigarette lighter 202 and facilitating the fixing of the bracket body 10 and the cigarette lighter 202. The fixing arm 30 can at least pre-fix the cigarette lighter 202, making it easier for the fixing bracket 100 to move the cigarette lighter 202 together, reducing the difficulty of assembling the cigarette lighter 202 with the fixing bracket 100 onto the circuit board 201.

[0079] In other embodiments, the fixing arm 30 can be omitted, and the cigarette lighter 202 and the bracket body 10 of the fixing bracket 100 can be glued together or tied together with cable ties. Alternatively, when the mounting feet 20 of the fixing bracket 100 are fixed to the circuit board 201, the cigarette lighter 202 can be directly clamped onto the circuit board 201.

[0080] In some embodiments, the fixing bracket 100 has a bracket body 10, mounting feet 20, and fixing arms 30. The fixing bracket 100 can be configured with different structures, each structure performing its own function and cooperating with each other. The fixing arms 30 can stably fix the cigarette lighter 202, making it easy for the bracket body 10 to maintain contact with the cigarette lighter 202 to maintain electrical contact with the cigarette lighter 202. And through the mounting feet 20, the cigarette lighter 202 is stably fixed to the circuit board 201 and electrically connected to the circuit board 201.

[0081] In some embodiments, the fixing arm 30 is connected to the first fitting part 11 so that the fixing arm 30 can cooperate with the first fitting part 11 to directly constrain the peripheral wall of the cigarette lighter 202. The peripheral wall of the cigarette lighter 202 has a larger area than the end wall, so the fixing arm 30 cooperates with the first fitting part 11 to achieve a better limiting and fixing effect.

[0082] Understandably, in some embodiments, the mounting feet 20 are provided in multiples and distributed on both sides of the fixing arm 30 to improve the stability of the fixing bracket 100 fixed to the circuit board 201.

[0083] In some embodiments, the fixing arm 30 is configured to undergo elastic deformation and is configured to apply an elastic force toward the support body 10 to the cigarette lighter 202. The bending deformation of the fixing arm 30 can occur inside the fixing arm 30 or at the connection between the fixing arm 30 and the support body 10.

[0084] The fixing arm 30 presses the cigarette lighter 202 against the bracket body 10, thereby stabilizing the cigarette lighter 202. Furthermore, the fixing arm 30 can automatically and stably fix the cigarette lighter 202 by elastically deforming and pressing against it, and can adapt to the different shapes of different cigarette lighters 202.

[0085] In other embodiments, the fixed arm 30 is not prone to elastic deformation. The fixed arm 30 and the bracket body 10 may have a portion of their structure not fitting the cigarette lighter 202. The fixed arm 30 and the bracket body 10 form a cage to frame the cigarette lighter 202 within the constraint space 40 to pre-fix the cigarette lighter 202. Subsequently, the conductive bolt 2022 of the cigarette lighter 202 and the bracket body 10 are fixedly connected to fix the cigarette lighter 202.

[0086] In some embodiments, the fixing arm 30 is configured as a hoop structure. The fixing arm 30 is configured to clamp the cigarette lighter 202 to the support body 10. The hoop structure makes the size of the fixing arm 30 relatively fixed and has good resistance to deformation, thereby enabling the fixing arm 30 to be stably clamped to the outside of the cigarette lighter 202, reducing the possibility of the cigarette lighter 202 being dislodged from the fixing support 100 due to vibration or impact, and improving the stability of fixing the cigarette lighter 202.

[0087] The fixed arm 30 uses elastic deformation to clamp the cigarette lighter 202 to the support body 10, and the elastic force applied by the fixed arm 30 to the cigarette lighter 202 improves the stability of the fixed arm 30 clamping the cigarette lighter 202.

[0088] In some embodiments, the fixing arms 30 are in two sets. One set of fixing arms 30 is provided on each of the opposite sides of the first fitting portion 11 of the support body 10, with a gap between the two sets of fixing arms 30, thereby adapting to the shape of the cigarette lighter 202 when clamping it. In other embodiments, the fixing arms 30 are in one set, provided on one of the opposite sides of the first fitting portion 11 of the support body 10, with a gap between the fixing arms 30 and the other side of the first fitting portion 11, to adapt to the shape of the cigarette lighter 202 when clamping it.

[0089] In some embodiments, the fixing bracket 100 is a one-piece molded structure. The fixing bracket 100 has good structural stability, improving the reliability of fixing the cigarette lighter 202 and electrically connecting it to the cigarette lighter 202, and also helps to reduce the manufacturing difficulty of the fixing bracket 100 and the difficulty of assembling the cigarette lighter 202. It is understood that in some embodiments, the fixing bracket 100 is formed by stamping or cutting. In other embodiments, the fixing bracket 100 is formed by welding.

[0090] See Figure 2 , Figure 6 and Figure 7 In some embodiments, the cigarette lighter assembly 200 further includes an electrode connector 203 and an insulator 204. The electrode connector 203 is fixedly connected to the cigarette lighter 202 and the circuit board 201, and electrically connected to the second electrode of the cigarette lighter 202 and the circuit board 201. The insulator 204 is disposed on the fixing bracket 100 and separates the fixing bracket 100 and the electrode connector 203. The electrode connector 203 passes through and is soldered to the circuit board 201 to simultaneously achieve electrical connection with the circuit board 201.

[0091] By providing an insulating component 204, the electrode connector 203 is prevented from contacting the fixed bracket 100, thus avoiding a short circuit between the first and second electrodes of the cigarette lighter 202 and ensuring a stable and safe electrical connection between the cigarette lighter 202 and the circuit board 201. Furthermore, the fixed bracket 100 stably secures the cigarette lighter 202 and the circuit board 201, thereby maintaining a stable electrical connection between them and ensuring stable electrical transmission in the cigarette lighter 202.

[0092] Understandably, in some embodiments, the insulating member 204 is disposed on the second contact portion 12 and separates the second contact portion 12 from the electrode connector 203. The insulating member 204 prevents the second contact portion 12 and the electrode connector 203 from being attached together, thereby preventing short circuit between the fixing bracket 100 and the electrode connector 203. Furthermore, the position of the insulating member 204 facilitates the separation of the second electrode of the cigarette lighter 202 from the fixing bracket 100, thereby preventing short circuit between the fixing bracket 100 and the second electrode of the cigarette lighter 202.

[0093] In some embodiments, the cigarette lighter 202 is provided with a conductive bolt 2022 serving as its second electrode. The conductive bolt 2022 is disposed on the end wall of the cigarette lighter 202. The conductive bolt 2022 sequentially presses the electrode connector 203, the insulating member 204, and the second mating portion 12 against the end wall of the cigarette lighter 202. Furthermore, the conductive bolt 2022 and the electrode connector 203 are electrically connected.

[0094] The conductive bolt 2022 can fix both the fixed bracket 100 and the electrode connector 203 to the cigarette lighter 202, and at the same time, it can serve as the second electrode of the cigarette lighter 202 to enable the electrode connector 203 to conduct electricity. It serves multiple purposes and helps to save space occupied by assembling the cigarette lighter 202.

[0095] Understandably, in some embodiments, the insulating element 204 and the separator 2023 cooperate to separate the conductive bolt 2022 from the cigarette lighter socket 2021 and the fixing bracket 100.

[0096] See Figure 3 , Figure 7 and Figure 8 In some embodiments, the electrode connector 203 has a connection port 2031. The insulating member 204 has an alignment port 2041. The second mating portion 12 has a clearance port 121. The conductive bolt 2022 passes through the connection port 2031, the alignment port 2041, and the clearance port 121 to connect with the second electrode of the cigarette lighter 202. Parts of the separator 2023 and / or parts of the insulating member 204 protrude into the clearance port 121 of the second mating portion 12 to prevent short circuit between the conductive bolt 2022 and the second mating portion 12.

[0097] The conductive bolt 2022 passes through the connection port 2031 to secure the electrode connector 203, facilitating its fixation. The conductive bolt 2022 passes through the alignment port 2041 to position the insulating component 204, ensuring that the insulating component 204 effectively prevents short circuits between the first and second electrodes of the cigarette lighter 202. The conductive bolt 2022, which electrically connects the second electrode of the cigarette lighter 202 to the circuit board 201, can pass through the clearance port 121 to establish a connection. By providing the clearance port 121, the area of ​​the support body 10 that fits against the cigarette lighter 202 can be maximized while facilitating the electrical connection of the second electrode, thereby improving the stability of fixing the cigarette lighter 202 and the stability of the electrical connection of the first electrode.

[0098] See Figure 3 and Figure 4In some embodiments, the circuit board 201 has a clearance area 2011. The cigarette lighter 202 is at least partially located in the clearance area 2011. The mounting bracket 100 can secure the cigarette lighter 202 to the clearance area 2011, saving wiring space and reducing the space occupied by assembling the cigarette lighter 202 by making the cigarette lighter 202 and the circuit board 201 more compact.

[0099] In some embodiments, the circuit board 201 has a first mounting port 2012 and a second mounting port 2013. A fixing bracket 100 is fixedly inserted into the first mounting port 2012. An electrode connector 203 is fixedly inserted into the second mounting port 2013.

[0100] The first assembly port 2012 facilitates the positioning of the fixing bracket 100 and can pre-fix the fixing bracket 100 to reduce the difficulty of establishing an electrical connection between the fixing bracket 100 and the circuit board 201. The second assembly port 2013 facilitates the positioning of the electrode connector 203 and can pre-fix the electrode connector 203 to reduce the difficulty of establishing an electrical connection between the electrode connector 203 and the circuit board 201.

[0101] It is understood that in some embodiments, the first assembly port 2012 and the second assembly port 2013 are distributed around the periphery of the clearance area 2011 in order to fix the cigarette lighter 202 to the clearance area 2011.

[0102] See Figures 3 to 5 In some embodiments, the insulating member 204 is provided with a guide groove 2042. The electrode connector 203 is disposed in the guide groove 2042. The insulating member 204 may have a protruding edge on its surface to form the guide groove 2042, or the insulating member 204 may have a recessed surface to form the guide groove 2042.

[0103] The guide groove 2042 can constrain the position of the electrode connector 203, so that when the fixed bracket 100 is inserted into the first assembly port 2012, the electrode connector 203 can be aligned with the second assembly port 2013, which facilitates the insertion of the electrode connector 203 into the second assembly port 2013 and simplifies the assembly process.

[0104] See Figure 4 , Figure 5 and Figure 6 In some embodiments, the fixing bracket 100 is used as follows:

[0105] The cigarette lighter 202 is inserted into the constraint space 40 of the fixed bracket 100, and the fixed arm 30, in conjunction with the bracket body 10, clamps the cigarette lighter 202. The insulating component 204 and the electrode connector 203 are fixed to the fixed bracket 100 by the conductive bolt 2022 of the cigarette lighter 202. The mounting legs 20 of the fixed bracket 100 are inserted into the first mounting port 2012 of the circuit board 201, and the electrode connector 203 is inserted into the second mounting port 2013 of the circuit board 201. The mounting legs 20 of the fixed bracket 100 and the circuit board 201 are welded at the first mounting port 2012, and the electrode connector 203 and the circuit board 201 are welded at the second mounting port 2013. The cigarette lighter 202 is fixed to the circuit board 201 along with the fixed bracket 100 and is electrically connected.

[0106] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
