[0043] To make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0044] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present utility model and should not be construed as a limitation of the present utility model.

[0045] As Figure 1 shown, this embodiment provides a refrigerator, which includes an inner liner 1 and a storage rack 2 installed inside the inner liner 1.

[0046] The inner liner 1 forms the storage space inside the refrigerator, including the bottom, side walls and top cover part, and cooperates with the refrigerator door body to form a sealed cavity as a whole, ensuring that cold air can be evenly distributed in the entire internal space and providing a stable and low-temperature storage environment. The inner liner 1 can be made of materials such as high-density plastic or stainless steel. Heat-insulating materials, such as polyurethane foam, are also filled between the inner liner 1 and the refrigerator outer shell to play a role in heat insulation and heat preservation.

[0047] As Figure 2 shown, the storage rack 2 is the main component for storing food inside the refrigerator, and it includes a storage board 21 made of glass, metal or high-strength plastic. The storage rack 2 can be fixed on the wall of the inner liner 1 through a card slot or a bracket to provide a stable storage space. The storage rack 2 can also be set as an adjustable structure, which can be moved up and down according to needs to flexibly adjust the height of the storage space and adapt to the storage requirements of foods of different sizes. The storage rack 2 reasonably divides and utilizes the internal space of the refrigerator, enabling foods to be stored separately, avoiding stacking and chaos, and improving the tidiness and convenience of storage.

[0048] A front trim strip 22 is provided on the outer side of the storage board 21. The front trim strip 22 can be made of high-strength plastic or metal materials, so as to provide better strength, durability and decorative effect. The front trim strip 22 can be designed as an embedded structure and installed at the front end of the storage rack 2 through a card slot or a fixing part to ensure the tight combination of the front trim strip 22 and the storage board 21 and prevent it from loosening easily.

[0049] It should be noted that the outer side of the storage board 21 mentioned here refers to the edge side of the storage board 21 facing the refrigerator door. On the contrary, the inner side of the storage board 21 refers to the edge side facing the inner wall of the refrigerator liner 1 relative to its outer side.

[0050] The storage rack 2 further includes a covering member 5 arranged on the inner side of the storage board 21. The electrical component 3 is arranged in the covering member 5, which can enhance the functionality and user experience of the refrigerator. The electrical component 3 includes lamp beads, light strips, cameras, etc. In this embodiment, the electrical component 3 is a light strip, and the light strip can be a flexible LED light strip, which has the characteristics of being bendable, adjustable in length, and convenient to install. Through the light strip, a uniform lighting effect can be provided, and a surrounding lighting can be formed to reduce lighting dead corners. The length and shape of the light strip can be adjusted according to the size and shape of the storage rack 2. In addition to the basic lighting function, the light strip can also be used as part of the ambient lighting to create different light and shadow effects and improve the aesthetics inside the refrigerator. For example, when using the refrigerator at night, a warm atmosphere can be created through soft lighting.

[0051] The lighting of traditional refrigerators is mostly concentrated on the top, which is easily blocked by the items on the storage rack 2, resulting in uneven light distribution. Installing a light strip on the storage rack 2 can provide a more uniform light coverage. No matter what items are placed on the storage rack 2, it can ensure sufficient lighting, facilitating users to view and take food.

[0052] The light strip can also be used as an indicator light for the refrigerator status. For example, lights of different colors can indicate different working states of the refrigerator (such as normal working, fault alarm, too high or too low temperature, etc.), helping users to understand the operation of the refrigerator in a timely manner.

[0053] In other embodiments of the present utility model, the electrical component 3 can also be a small high-definition camera, which can realize real-time monitoring of the inside of the refrigerator through the perspective of the storage rack 2.

[0054] As Figure 3 shown, a conductive structural member 31 is arranged on the side of the covering member 5, and the electrical component 3 and the conductive structural member 31 are electrically connected through a conductive connecting member. In this embodiment, the conductive connecting member is an elastic conductive connecting member 32, and the elastic conductive connecting member 32 abuts against the conductive structural member 31 in a compressed state. The refrigerator further includes a power supply unit 4, and the power supply unit 4 is electrically connected to the power supply and the conductive structural member 31.

[0055] In this embodiment, the electrical component 3 (such as a light strip) and the conductive structural member 31 are electrically connected through an elastic conductive connecting member 32, and the elastic conductive connecting member 32 abuts against the conductive structural member 31 in a compressed state. The conductive structural member 31 is arranged on the side of the covering member 5 and is made of a highly conductive metal material, such as copper or silver-plated copper alloy, etc.

[0056] The power supply unit 4 is arranged outside the inner liner 1 of the refrigerator and is electrically connected to the conductive structural member 31 through a power supply extension member 41, providing an electric energy transmission channel between the power supply and the conductive structural member 31. The power supply unit 4 is connected to the power supply system of the refrigerator to ensure stable power supply.

[0057] The elastic conductive connecting member 32 presses the electrical component 3 and the conductive structural member 31 tightly through its own elastic force to ensure good electrical contact at all times. Whether during installation or use, the elastic conductive connecting member 32 can automatically adjust its position to adapt to minute displacements and vibrations, preventing poor contact or disconnection. The elastic conductive connecting member 32 can adapt to changes under different installation environments and usage conditions, such as temperature changes and mechanical vibrations. In the compressed state, the elastic conductive connecting member 32 can automatically adapt to these changes, maintain stable electrical contact, and ensure the normal operation of the electrical component 3.

[0058] Moreover, the elastic design of the elastic conductive connecting member 32 can reduce wear caused by long-term use. The elastic force of the spring can ensure that the contact surface always maintains an appropriate pressure, reducing friction and wear on the contact surface and extending the service life of the electrical connection.

[0059] As Figure 4 shown, the covering member 5 includes a main covering member 51 and a side covering member 52. The side covering member 52 is hermetically spliced to the side of the main covering member 51. The electrical component 3 is arranged inside the main covering member 51, and the conductive structural member 31 is arranged inside the side covering member 5.

[0060] The covering member 5 and the side covering member 52 form a complete protection structure through hermetic splicing. The electrical component 3 is arranged inside the main covering member 51, and the conductive structural member 31 is arranged inside the side covering member 52. The main covering member 51 is designed according to the shape and size of the storage board 21, presenting a box-shaped or groove-shaped structure for accommodating and protecting the electrical component 3.

[0061] The main covering member 51 can be made of high-strength plastic or metal materials, having good mechanical strength and durability, while ensuring that the internal electrical component 3 is not affected by the external environment. The side covering member 52 is matched with the side of the main covering member 51. The size and shape of the side covering member 52 are designed according to the structure of the main covering member 51 to ensure that the two can be closely spliced.

[0062] The main covering member 51 and the side covering member 52 are connected through hermetic splicing, and can adopt methods such as snap-fastening, embedding, or bonding to ensure tight combination and sealing between the two.

[0063] In this embodiment, before installation, the side covering member 52 and the main covering member 51 made of plastic material can be locally melted through a melting process, and then the side covering member 52 is installed and fixed to ensure that the two can be tightly combined through the melting process. Through the melting process, the rear trim strip and the decorative cover can be tightly combined in a molten state to form a seamless integral structure, effectively preventing the infiltration of moisture and humidity.

[0064] At the splicing joint, a sealing strip or sealant can also be used to prevent dust, moisture, and other impurities from entering the interior of the covering member 5, protecting the internal electrical components 3 and the conductive structural members 31.

[0065] A conductive structural member 31 is provided inside the side covering member 52. The conductive structural member 31 is a highly conductive metal sheet or metal strip for connecting the electrical component 3 and an external power source.

[0066] As Figure 5a Figure 5b As shown, a positioning structure portion 511 is provided inside the main covering member 51. The positioning structure portion 511 forms a groove for accommodating the electrical component 3, and the electrical component 3 is fixedly accommodated in the groove of the positioning structure portion 511.

[0067] The positioning structure portion 511 is designed as a groove or an embedded groove formed inside the main covering member 51, and its shape and size are customized according to the specifications of the electrical component 3 to ensure that the electrical component 3 can be stably accommodated therein. The positioning structure portion 511 is integrally formed with the main covering member 51 and made of the same high-strength material to ensure the strength and durability of the overall structure.

[0068] The inside of the groove can be designed with buckles, clamping grooves, or elastic clamping structures for further fixing the electrical component 3 to prevent it from moving or falling off during use.

[0069] The main covering member 51 and the side covering member 52 are spliced to form a closed cavity. The electrical component 3 is disposed inside the closed cavity, and the portion of the closed cavity between the electrical component 3 and the storage board 21 is made of a transparent material.

[0070] The side covering member 52 and the main covering member 51 are spliced to form a closed cavity, ensuring that the electrical component 3 is in a relatively enclosed and protected environment. The transparent material portion is located at the top or front side of the closed cavity and is adjacent to the storage board 21 to ensure that light can pass through the transparent material portion to illuminate the items on the storage rack 2. The transparent material portion can be made of materials with high transparency and durability, such as polycarbonate, acrylic, or tempered glass, to ensure good optical performance and mechanical strength.

[0071] An insertion and positioning portion 521 that matches and fits the inner structure of the closed cavity is formed inside the side covering member 52, and the insertion and positioning portion 521 surrounds the electrical component 3 inside the closed cavity.

[0072] The insertion and positioning portion 521 is designed on the inner side of the side covering member 52. The insertion and positioning portion 521 is integrally formed with the side covering member 52 and matches the inner structure of the closed cavity. The shape and size of the insertion and positioning portion 521 are designed according to the internal structure of the closed cavity to ensure that it can closely fit the closed cavity. The shape and size of the insertion and positioning portion 521 match the inner structure of the closed cavity and can be a convex or insert structure. Through these structures, the close fit between the two is achieved, and the close matching between the insertion and positioning portion 521 and the inner structure of the closed cavity enhances the overall assembly stability between the side covering member 52 and the main covering member 51 and ensures the accurate positioning of the electrical component 3 inside the closed cavity.

[0073] The insertion and positioning portion 521 surrounds the position of the electrical component 3 to form a sealing ring structure. Through the insertion and positioning portion 521, moisture and humidity can be effectively prevented from entering the closed cavity, protecting the electrical component 3 from the influence of a humid environment. The closed design of the insertion and positioning portion 521 enhances the sealing performance between the side covering member 52 and the main covering member 51, ensuring that the environment around the electrical component 3 remains dry and clean and extending the service life of the electrical component 3.

[0074] As Figure 6 shown, in this embodiment, the conductive structure member 31 is a plate-shaped metal sheet embedded in the side of the side covering member 52, and the elastic conductive connecting member 32 extends laterally along the electrical component 3 and abuts against the plate-shaped metal sheet.

[0075] The plate-shaped metal sheet is designed as a thin sheet and is embedded in the side of the side covering member 52. Its shape and size are designed according to the design of the side covering member 52 to ensure close fit and good electrical conductivity. The plate-shaped metal sheet is made of a high-conductivity metal material, such as copper or silver-plated copper alloy, to ensure the high efficiency and stability of electric energy transmission. The plate-shaped metal sheet is fixed in the side of the side covering member 52 by embedding or a card slot to ensure its stability and non-movement.

[0076] As Figure 7 shown, in another embodiment of the present invention, the conductive structure member 31 is a bent metal sheet, which includes a first metal sheet embedded in the side of the side covering member 52 and a second metal sheet bent from the first metal sheet toward the electrical component 3, and the elastic conductive connecting member 32 is vertically arranged from the surface of the electrical component 3 and abuts against the second metal sheet.

[0077] The first metal sheet is embedded in the side of the side cover 52. The second metal sheet is bent along the first metal sheet towards the electrical component 3 to form an L-shaped structure. The bent metal sheet conductive structure 31 increases the flexibility and stability of electrical contact through the bending design of the first metal sheet and the second metal sheet. The elastic conductive connector 32 is in vertical contact with the second metal sheet, ensuring stable electrical connection of the electrical component 3 at different positions and angles.

[0078] In this embodiment, positive and negative elastic conductive connectors 32 are respectively arranged at both ends of the electrical component 3, and positive and negative conductive structures 31 are respectively arranged on both sides of the cover 5 correspondingly. The positive and negative elastic conductive connectors 31 arranged at both ends provide multiple-point electrical contact, ensuring the stability and efficiency of power transmission, and are applicable to electrical components that are long or require high current.

[0079] As Figure 8 shown, in another embodiment of the present utility model, positive and negative elastic conductive connectors 32 are arranged in parallel at one end of the electrical component 3, and positive and negative conductive structures 31 are arranged correspondingly on one side of the cover 5. The positive elastic conductive connector 32 and the negative elastic conductive connector 32 are integrated at one end of the light strip to form a parallel arrangement, facilitating centralized connection.

[0080] As Figure 9 shown, the elastic conductive connector 32 is a metal spring pin, which includes a cavity part and a pin body part extending from the cavity part. A spring is arranged in the cavity part to control the telescopic movement of the pin body part. The cavity part is connected to the electrical component, and the pin body part abuts against the conductive structure 31.

[0081] In this embodiment, the cavity part is welded to the electrical component 3, and the pin body part abuts against the conductive structure.

[0082] In another embodiment of the present utility model, the electrical component 3 is welded to a connecting seat, and a threaded fit connection is formed between the connecting seat and the cavity part. The threaded design ensures a tight connection between the cavity part and the electrical component, and at the same time facilitates installation and disassembly, improving the convenience of maintenance and replacement.

[0083] In another embodiment of the present utility model, the elastic conductive connector 32 is an elastic metal sheet, and the elastic metal sheet abuts against the electrical component and the conductive structure respectively.

[0084] As Figure 10 and Figure 11As shown, in another embodiment of the utility model, the inner tank also includes a storage plate support 11 embedded in its side, the storage plate support 11 is provided with a slot for clamping the storage plate, and the power supply part is arranged in the storage plate support 11 and is electrically connected to the conductive structure 31.

[0085] A through groove 12 is provided in the inner container, and the through groove 12 is arranged on the side of the inner container and runs through the thickness of the entire side wall. The through groove 12 is used to accommodate and fix the storage board support 11, and the storage board support 11 is arranged in the through groove 12. A card slot is provided on the storage board support 11, which is used to card the storage board so that the storage board can be firmly installed on the support, and through the design of the card slot, the storage board can be conveniently plugged in, installed and removed.

[0086] The conductive structural member 31 is a bent metal sheet, which includes a first metal sheet embedded in the side edge of the side covering member and a second metal sheet bent along the first metal sheet toward the electrical component 3. The conductive connecting member 32 extends laterally from the surface of the electrical component 3 and abuts against the first metal sheet. The power supply portion is provided with a power supply extension member, which extends backward from the storage plate support member 11 and abuts against the second metal sheet.

[0087] The metal sheet is bent into an L-shape, and the bent second metal sheet is used as a transition piece, so that the conductive connecting piece 32 and the conductive portion extension piece facing different directions can be electrically connected.

[0088] In another embodiment of the present invention, the conductive structure 31 is arranged at the rear end of the storage plate support 11 and is arranged toward the covering member. The conductive connecting member 32 is vertically arranged from the surface of the electrical component 3 and passes through the covering member to abut against the conductive structure 31.

[0089] In this embodiment, the conductive structure 31 is installed at the rear end of the storage plate support 11 and is arranged toward the covering member, so that the size of the covering member can be reduced, thereby providing more space for the installation of other components and optimizing the internal structure design of the refrigerator. In addition, the conductive structure 31 is installed at the rear end of the storage plate support 11, making it a modular component that is easy to install and disassemble.

[0090] In summary, this embodiment provides a refrigerator, which includes an inner liner and a storage rack installed inside the inner liner. A covering member and electrical components such as a light strip are provided inside the storage rack. The light strip forms a circumferential lighting layout, providing uniform light coverage. The light strip enhances the lighting effect and avoids the occlusion of traditional top lighting by items. The elastic conductive connecting piece presses the electrical component against the conductive structural member through elastic force, ensuring stable electrical contact and adapting to different installation environments and usage conditions. Through the design of the elastic conductive connecting piece, stable electrical contact and efficient power transmission are achieved inside the refrigerator, and the protection of internal electrical components is enhanced, improving the overall reliability and user experience.

[0091] The structure of the power supply part in this embodiment will be further described below.

[0092] As Figure 12 、 Figure 13a and Figure 13b shown, the refrigerator further includes a power supply part 4, and the power supply part 4 is arranged outside the inner liner 1. The inner liner 1 is provided with a first through hole, and the power supply part 4 is provided with a power supply extension piece 41. The power supply extension piece 41 is connected to the power supply, passes through the first through hole, and forms an electrical contact with the electrical component 3.

[0093] A conductive structural member 31 is arranged on the side of the electrical component 3. After the power supply extension piece 41 is in electrical contact with the conductive structural member 31, it supplies power to the electrical component 3.

[0094] The power supply part 4 is used to supply power to the electrical component 3 in the storage rack 2. It is connected to the power supply system of the refrigerator, and transmits electrical energy to the electrical component 3 inside the inner liner 1 through the power supply extension piece 41. The power supply part 4 is installed outside the inner liner 1, which can effectively avoid occupying the internal space, keep the inside of the refrigerator clean and effectively utilized. At the same time, the external power supply part 4 is convenient for maintenance and repair and will not interfere with the storage and use inside the refrigerator.

[0095] The power supply extension piece 41 is made of a metal material with high conductivity, such as copper or silver-plated copper alloy, which has excellent electrical conductivity and corrosion resistance, ensuring efficient and lasting power transmission in the applicable environment of the refrigerator.

[0096] The power supply part 4 further includes a housing 42. The housing 42 accommodates the power supply extension piece 41. The housing 42 is installed outside the inner liner 1 and is provided with a second through hole that cooperates with the first through hole. The power supply extension piece 41 passes through the second through hole and the first through hole to form an electrical contact with the electrical component 3.

[0097] The housing 42 can protect and fix the power supply extension 41, and ensure the stability and safety of power transmission. The housing 42 can be fixed on the outer wall of the inner container 1 by gluing, buckling or other fixing devices to ensure its firmness and reliability. A second through hole matching the first through hole of the inner container 1 is provided on the housing 42 for the power supply extension 41 to pass through the housing 42 and the inner container 1 and connect with the internal electrical components 3. In order to prevent cold air leakage and external moisture from entering, a sealing ring or gasket and other structures can be designed at the connection between the second through hole and the first through hole to ensure good sealing performance of the through hole after the power supply extension 41 passes through. The housing 42 accommodates the power supply extension 41, provides physical protection, and prevents the power supply extension 41 from being affected by the external environment, such as dust, moisture, collision, etc. The housing 42 provides a stable support platform for the power supply extension 41 to maintain a reliable connection between the power supply extension 41 and the electrical components 3.

[0098] The power supply extension 41 is an elastic structural member and can telescopically move along the second through hole and the first through hole.

[0099] The power supply extension 41 is designed as an elastic structural member, so as to ensure the stability and reliability of electrical contact. During the use of the refrigerator, it may be slightly vibrated and displaced. The elastic structural member can adapt to these changes through its own telescopic movement, maintain the stable contact between the power supply extension 41 and the electrical components 3, and prevent poor contact or disconnection. And when the position of the storage rack 2 or the electrical components 3 changes slightly, the elastic structural member can also automatically adjust its position to ensure good electrical contact at all times. In the internal environment of the refrigerator, temperature changes may cause thermal expansion and contraction of materials. The elastic structural member can automatically adapt to these changes, maintain the stability of electrical contact, and prevent poor contact caused by temperature changes.

[0100] The elastic structural member can also absorb and buffer the externally applied impact force to prevent the power supply extension 41 and the electrical components 3 from being damaged by external forces. Especially during handling or use, the buffering effect of the elastic structural member can effectively protect the integrity of the electrical connection.

[0101] Moreover, since the elastic structural member can freely expand and contract within a certain range, precise alignment is not required during installation. Only need to roughly insert the power supply extension 41 into the through hole, and the elastic structural member will automatically adjust to the appropriate position, which simplifies the installation process and improves the installation efficiency.

[0102] Such as Figure 13b and Figure 14As shown, the power supply extension member 41 includes an elastic device 411 and a contact member 412 that abuts against the elastic device 411. The elastic device 411 controls the telescopic movement of the contact member 412 along the through hole. The elastic device 411 is a spring. The power supply extension member 41 is formed with a cavity for accommodating the spring. The end of the spring is connected to a power cord, and the top end of the spring extends into the cavity and abuts against the contact member 412.

[0103] In this embodiment, the power supply extension member 41 is composed of an elastic device 411 and a contact member 412. The elastic device 411 controls the telescopic movement of the contact member 412 along the through hole to ensure the stability and reliability of electrical contact. One end of the spring is connected to the power cord and fixed by welding or clamping to ensure that electrical energy can be stably transmitted to the spring. The power cord is connected to the power supply system of the refrigerator to provide a stable power input.

[0104] The contact member 412 abuts against the top end of the spring and is made of a highly conductive metal material to ensure good electrical conductivity. The shape of the contact member 412 can be cylindrical, flat or other suitable shapes to adapt to different installation environments and usage requirements. In this embodiment, the contact member 412 is a hollow cylindrical structure and is formed with a cavity for accommodating the spring. The top end of the spring extends into the cavity and abuts against the contact member 412. The spring presses the contact member 412 against the electrical component 3 by its own elastic force to ensure good electrical contact at all times.

[0105] Specifically, in this embodiment, in order to ensure that the power supply extension member 41 can directly contact the conductive structure member 31 on the side of the electrical component 3, a margin of 2 mm needs to be left on both the left and right sides of the storage board 21. If the installation position of the storage board 21 is inaccurate, it may be the case that one side is 0 mm and the other side is 4 mm. To ensure normal use, the power supply extension member 41 should extend at least 16 mm out of the inner container without being squeezed by the storage rack 2.

[0106] The elastic device 411 and the contact member 412 in the power supply extension member 41 are in direct contact. Therefore, the position where the inner cavity of the contact member 412 contacts the spring is designed as a plane, and the spring is sleeved in the cavity of the contact member 412. When the contact member 412 is not squeezed, the spring should at least maintain a pre-compressed state of 10%, pressing the contact member 412 against the limiting surface in the housing 42. The movement stroke of the contact member 412 is 6 mm, and the maximum compression amount of a normal round wire spring is 40% of its total height. According to this data, the spring height is set to at least 20 mm to meet the usage requirements.

[0107] Through the above design, the power supply extension member 41 can provide stable and reliable electrical contact during the actual use of the refrigerator, ensuring the normal operation of the electrical component 3 inside the refrigerator.

[0108] The housing 42 is provided with a guide rib 421, the guide rib 421 is arranged toward the second through hole, and the spring is sleeved on the guide rib 421. The housing 42 is provided with a guide groove 422, the contact member 412 is arranged in the guide groove 422, abuts against the guide groove 422, and moves along the guide groove 422.

[0109] The guide rib 421 is arranged inside the housing 42, and is a slender columnar structure. The cross section can be circular, square or other shapes, facing the second through hole, and the length of the guide rib 421 is designed according to the size of the housing 42 and the length of the spring. The guide rib 421 guides the spring to move along a predetermined path to ensure that the spring does not deviate from the direction during the expansion and contraction process. By providing the guide rib 421, the spring always remains in the correct position during compression and extension to avoid bending or jamming. The guide rib 421 can provide a fixed support, so that the spring is not prone to lateral deformation when subjected to force. This ensures that the elastic force of the spring always acts in the correct direction and ensures the stability of the electrical contact.

[0110] The guide groove 422 is arranged inside the housing 42 and is located on the path of the contact 412. The specific position of the guide groove 422 can be designed according to the design of the housing 42 and the movement trajectory of the contact 412, and the shape of the guide groove 422 matches the shape of the contact 412. The guide groove 422 provides a precise movement path, and the contact 412 moves along a predetermined trajectory in the guide groove 422 to avoid unstable electrical contact caused by path deviation. Through the guidance of the guide groove 422, the contact 412 can be kept in the correct position at any time. The design of the guide groove 422 can prevent the contact 412 from deviating or getting stuck during the movement.

[0111] like Figure 15 and Figure 16 As shown, the shell 42 includes a first shell 42a and a second shell 42b which are spliced ​​to each other. The first shell 42a is provided with a protruding guide rib 421, and the second shell 42b is provided with the guide groove 422.

[0112] The shell 42 is composed of a first shell 42a and a second shell 42b which are spliced ​​to each other, and presents a semi-enclosed box-like structure, and a protruding guide rib 421 is provided in the first shell 42a. The shape and size of the second shell 42b are set according to the shape of the inner liner 1, matching the shape and size of the inner liner 1, and can be tightly spliced ​​with the inner liner 1. The second shell 42b also presents a semi-enclosed box-like structure, spliced ​​with the first shell 42a, and a guide groove 422 is provided in the second shell 42b.

[0113] The first housing 42a and the second housing 42b are joined together to form a complete protective housing 42, which provides stable structural support, ensuring not only the overall strength of the housing 42 but also facilitating the installation and disassembly of the housing 42. The closed structure of the housing 42 can effectively protect the internal power supply extension 41 from the influence of the external environment, such as dust, moisture, and mechanical damage. The first housing 42a and the second housing 42b are connected by snap fasteners, including a protrusion provided on the second housing 42b and a groove structure on the first housing 42a. The snap fastener structures are evenly distributed around the circumference of the housing 42 to ensure the connection strength and stability of the entire housing 42.

[0114] A sealing ring can be provided at the joint of the first housing 42a and the second housing 42b. The closed design effectively prevents dust, moisture, and other impurities from entering the interior of the housing 42, protecting the internal power supply extension 41 and other components from the influence of the external environment.

[0115] The first housing 42a and the second housing 42b are also provided with opposing mating U-shaped grooves, which form a wire hole for the power supply wire after the two are joined together.
