[0029] In order to make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions of the present application will be described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0030] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, in which the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0031] As shown in Fig. 1, the present embodiment provides a refrigerator, which comprises an inner container 1 and a shelf 2 installed inside the inner container 1.

[0032] The inner container 1 constitutes a storage space inside the refrigerator. The inner container 1 comprises a bottom, a side wall, and a top cover portion, cooperates with the refrigerator door body to form a closed cavity, ensures that cold air can be uniformly distributed in the entire internal space, and provides a stable and low-temperature storage environment. The inner container 1 can be made of high-density plastic or stainless steel and the like. A heat insulation material such as polyurethane foam is also filled between the inner container 1 and the refrigerator shell to play a heat insulation and heat preservation role.

[0033] As shown in FIG. 2, the shelf 2 is a main component for storing food in the refrigerator. The shelf 2 includes a shelf plate 21 made of glass, metal or high-strength plastic. The shelf 2 can be fixed on the wall of the inner container 1 through a clamping groove or a support to provide a stable storage space. The shelf 2 can also be provided as an adjustable structure. The shelf 2 is moved up and down as needed to flexibly adjust the height of the storage space to adapt to the storage needs of food of different sizes. The shelf 2 reasonably separates and utilizes the internal space of the refrigerator, allowing food to be stored in categories to avoid accumulation and confusion, and improving the cleanliness and convenience of storage.

[0034] A front trim 22 is provided on the outer side of the shelf plate 21. The front trim 22 can be made of high-strength plastic or metal material to provide better strength, durability and decorative effect. The front trim 22 can be designed as an embedded structure and installed at the front end of the shelf 2 through a clamping groove or a fixing member to ensure that the front trim 22 is tightly combined with the shelf plate 21 and is not easy to loosen.

[0035] It should be noted that the outer side of the shelf plate 21 referred to herein refers to the edge side of the shelf plate 21 facing the door of the refrigerator. In contrast, the inner side of the shelf plate 21 refers to the edge side facing the inner wall of the inner container 1 of the refrigerator relative to the outer side.

[0036] The shelf 2 further includes a covering member 5 provided on the inner side of the shelf plate 21. The electrical element 3 is provided in the covering member 5 to enhance the functionality of the refrigerator and the user experience. The electrical element 3 includes a lamp bead, a lamp strip and a camera, etc.

[0037] In the present embodiment, the electrical element 3 includes a lamp strip. The lamp strip can be a flexible LED lamp strip, which has the characteristics of being bendable, adjustable in length and convenient to install. The lamp strip can provide uniform lighting effect and form a surrounding illumination to reduce the illumination dead angle.

[0038] The length and shape of the lamp strip can be adjusted according to the size and shape of the shelf 2. In addition to the basic lighting function, the lamp strip can also be part of the ambient lighting to create different lighting effects and improve the aesthetics of the interior of the refrigerator. For example, when the refrigerator is used at night, a soft light can create a warm atmosphere.

[0039] The lighting of the conventional refrigerator is mostly concentrated on the top, which is easy to be blocked by the items on the shelf 2, resulting in uneven light distribution. By installing the lamp strip on the shelf 2, more uniform light coverage can be provided. No matter what items are placed on the shelf 2, sufficient illumination can be ensured to facilitate the user to view and access the food.

[0040] The lamp strip can also serve as an indicator light for the state of the refrigerator. For example, different colors of light can indicate different working states of the refrigerator (such as normal working, fault alarm, temperature being too high or too low, etc.), helping the user to timely understand the operation of the refrigerator.

[0041] In other embodiments of the application, the power consuming element 3 can also be a small high-definition camera, realizing real-time monitoring of the inside of the refrigerator.

[0042] As shown in FIG. 3, the cladding 5 side is provided with a conductive part 31. The power consuming element 3 and the conductive part 31 are electrically connected through a conductive connecting part 32.

[0043] In this embodiment, the conductive connecting part 32 is an elastic conductive connecting part 32, which abuts against the conductive part 31 in a compressed state. The refrigerator further comprises a power supply part 4, which is electrically connected to a power source and the conductive part 31.

[0044] In this embodiment, the power consuming element 3 (such as a lamp strip) and the conductive part 31 are electrically connected through the elastic conductive connecting part 32, and the elastic conductive connecting part 32 abuts against the conductive part 31 in a compressed state. The conductive part 31 is arranged on the side of the cladding 5. The conductive part 31 is made of a highly conductive metal material, such as copper or silver-plated copper alloy, etc.

[0045] The power supply part 4 is arranged outside the inner container 1 of the refrigerator. The power supply part 4 is electrically connected to the conductive part 31 to provide an electric energy transmission channel between the power supply and the conductive part 31. The power supply part 4 is connected to the power supply system of the refrigerator to ensure stable power supply.

[0046] The elastic conductive connecting part 32 compresses the power consuming element 3 and the conductive part 31 by its own elastic force, ensuring that good electrical contact is always maintained. Whether during installation or use, the elastic conductive connecting part 32 can automatically adjust the position to adapt to slight displacement and vibration, preventing poor contact or disconnection. The elastic conductive connecting part 32 can adapt to changes in different installation environments and use conditions, such as temperature changes and mechanical vibrations. The elastic conductive connecting part 32 can automatically adapt to these changes in a compressed state, maintain stable electrical contact, and ensure normal operation of the power consuming element 3.

[0047] In addition, the elastic design of the elastic conductive connecting part 32 can reduce wear caused by long-term use. The elastic force of the elastic conductive connecting part 32 can ensure that the contact surface always maintains appropriate pressure, reducing friction and wear on the contact surface, and prolonging the service life of the electrical connection.

[0048] As shown in FIG. 4, the cladding 5 comprises a main cladding 51 and a side cladding 52. The side cladding 52 is sealed and spliced to the side of the main cladding 51. The power consuming element 3 is arranged in the main cladding 51, and the conductive part 31 is arranged in the side cladding 5.

[0049] The main cover 51 and the side cover 52 are connected by sealing and splicing to form a complete protective structure. The electrical component 3 is arranged in the main cover 51, and the conductive part 31 is arranged in the side cover 52. The main cover 51 is designed according to the shape and size of the storage plate 21, and is in a box-shaped or groove-shaped structure, which is used to accommodate and protect the electrical component 3.

[0050] The main cover 51 can be made of high-strength plastic or metal material. The main cover 51 has good mechanical strength and durability, and can ensure that the internal electrical component 3 is not affected by the external environment. The side cover 52 cooperates with the side edge of the main cover 51. The size and shape of the side cover 52 are designed according to the structure of the main cover 51 to ensure that the two can be tightly spliced.

[0051] The main cover 51 and the side cover 52 are connected by sealing and splicing, which can be connected by buckling, embedding or bonding, etc., to ensure the tight combination and sealing between the two.

[0052] In this embodiment, the side cover 52 and the main cover 51 of plastic material can be partially melted by a melting process before installation, and then the side cover 52 is installed and fixed to ensure that the two can be tightly combined by the melting process. Through the melting process, the main cover 51 and the side cover 52 can be tightly combined in a molten state to form a seamless whole structure, effectively preventing the penetration of moisture and humidity.

[0053] Sealing strips or sealing glue can also be used at the splicing place to prevent dust, humidity and other impurities from entering the inside of the cover 5, protecting the internal electrical component 3 and the conductive part 31.

[0054] The side cover 52 is provided with a conductive part 31. The conductive part 31 is a high-conductivity metal sheet or metal strip, which is used to connect the electrical component 3 and the external power supply.

[0055] As shown in FIGS. 5a and 5b, the main cover 51 is provided with a positioning structure 511. The positioning structure 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 511.

[0056] The positioning structure 511 is designed as a groove or a slot formed in the main cover 51. The shape and size of the positioning structure 511 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 511 is integrally formed with the main cover 51 and is made of the same high-strength material to ensure the strength and durability of the whole structure.

[0057] The groove can be designed with buckles, clamping grooves or elastic clamping structures to further fix the electrical component 3 and prevent the electrical component 3 from moving or falling off during use.

[0058] The main cover 51 and the side cover 52 are spliced to form a closed cavity. The electrical component 3 is arranged in the closed cavity. The portion between the electrical component 3 and the storage plate 21 is made of transparent material.

[0059] The side cover 52 and the main cover 51 are spliced to form a closed cavity, ensuring that the electrical component 3 is in a relatively closed and protected environment. The transparent material portion is located at the top or front side of the closed cavity, adjacent to the storage plate 21, to ensure that light can pass through the transparent material portion to illuminate the items on the shelf 2. The transparent material portion can be made of high-transparency and durable materials such as polycarbonate, acrylic, or tempered glass to ensure good optical performance and mechanical strength.

[0060] The side cover 52 is formed with a plug-in positioning part 521 that matches the inside structure of the closed cavity. The plug-in positioning part 521 surrounds the electrical component 3 inside the closed cavity.

[0061] The plug-in positioning part 521 is designed inside the side cover 52. The plug-in positioning part 521 is integrally formed with the side cover 52 and matches the inside structure of the closed cavity. The shape and size of the plug-in positioning part 521 are designed according to the internal structure of the closed cavity to ensure that it can closely match the closed cavity. The shape and size of the plug-in positioning part 521 match the inside structure of the closed cavity, which can be a protrusion or an insert structure.

[0062] The close matching of the plug-in positioning part 521 and the inside structure of the closed cavity enhances the overall assembly stability between the side cover 52 and the main cover 51 and ensures the accurate positioning of the electrical component 3 in the closed cavity.

[0063] The plug-in positioning part 521 surrounds the position of the electrical component 3, forming a sealing ring structure. The plug-in positioning part 521 can effectively prevent moisture and humidity from entering the closed cavity, protecting the electrical component 3 from a humid environment. The sealing design of the plug-in positioning part 521 enhances the sealing performance between the side cover 52 and the main cover 51, ensuring that the environment around the electrical component 3 remains dry and clean, prolonging the service life of the electrical component 3.

[0064] As shown in FIG. 6, in this embodiment, the conductive part 31 is a plate-shaped metal sheet embedded in the side edge of the side cover 52. As shown in FIG. 3, the elastic conductive connecting part 32 extends laterally along the electrical component 3 and abuts against the plate-shaped metal sheet. The elastic conductive connecting part 32 extends along the length direction of the electrical component 3, i.e., along the width direction of the refrigerator.

[0065] The plate-shaped metal sheet is designed in a thin sheet shape and is embedded in the side edge of the side covering member 52. The shape and size of the plate-shaped metal sheet are designed according to the design of the side covering member 52 to ensure close fitting and good electrical conductivity. The plate-shaped metal sheet is made of a highly conductive metal material, such as copper or silver-plated copper alloy, to ensure the efficiency and stability of power transmission. The plate-shaped metal sheet is fixed in the side edge of the side covering member 52 by embedding or clamping to ensure its stability and prevent movement.

[0066] As shown in FIG. 7, in another embodiment of the present application, the conductive member 31 is a bent metal sheet 31, which includes a first metal sheet 311 embedded in the side edge of the side covering member 52 and a second metal sheet 312 bent towards the side of the electric element 3 along the first metal sheet 311, and the elastic conductive connecting member 32 is vertically arranged from the surface of the electric element 3 and abuts against the second metal sheet 312.

[0067] The first metal sheet 311 is embedded in the side edge of the side covering member 52, and the second metal sheet 312 is bent towards the side of the electric element 3 along the first metal sheet 311 to form an L-shaped structure. The bent metal sheet 31 increases the flexibility and stability of electrical contact through the bending design of the first metal sheet 311 and the second metal sheet 312. The vertical contact of the elastic conductive connecting member 32 with the second metal sheet 312 can be understood as the elastic conductive connecting member 32 being perpendicular to the second metal sheet 312, which ensures stable electrical connection of the electric element 3 at different positions and angles.

[0068] In this embodiment, the electric element 3 is provided with a positive elastic conductive connecting member 32a and a negative elastic conductive connecting member at both ends, and the covering member 5 is provided with a positive conductive member 31a and a negative conductive member on both sides. The provision of positive and negative elastic conductive members 31 at both ends provides multiple-point electrical contact, ensuring the stability and efficiency of power transmission, and is suitable for electric elements that are longer or require high current.

[0069] As shown in FIG. 8, in another embodiment of the present application, the electric element 3 is provided with a positive elastic conductive connecting member and a negative elastic conductive connecting member in parallel at one end, and the covering member 5 is provided with a positive conductive member 31a and a negative conductive member 31b on one side. The positive and negative elastic conductive connecting members 32 are integrated at one end of the lamp strip to form a parallel arrangement, facilitating centralized connection.

[0070] As shown in FIG. 9, the elastic conductive connecting member 32 is a metal spring needle, which includes a cavity part 321 and a needle part 322 extending from the cavity part 321, and a spring is arranged in the cavity part 321 to allow the needle part 322 to extend and retract. The cavity part 321 is connected to the electric element 3, and the needle part 322 abuts against the conductive member 31.

[0071] In the present embodiment, the cavity portion 321 is welded to the electric element 3, and the needle portion 322 is in abutment with the conductive member 31.

[0072] In another embodiment of the present application, the electric element 3 is welded to a connecting seat, and the connecting seat and the cavity portion 321 are threadedly connected. The threaded design ensures a tight connection between the cavity portion 321 and the electric element 3, and facilitates installation and disassembly, improving the convenience of maintenance and replacement.

[0073] In another embodiment of the present application, the elastic conductive connecting member 32 is an elastic metal sheet, which is in abutment with the electric element and the conductive member, respectively.

[0074] As shown in FIGS. 10 and 11, in another embodiment of the present application, the inner container 1 further comprises a storage plate support 11 embedded in the side thereof, which is provided with a clamping groove for clamping the storage plate. The power supply portion 4 is arranged in the storage plate support 11, and is electrically connected to the conductive member 31.

[0075] The inner container 1 is provided with a through groove 12. The through groove 12 is arranged in the side wall of the inner container 1 and penetrates the entire thickness of the side wall. The through groove 12 is used to accommodate and fix the storage plate support 11, which is arranged in the through groove 12. The storage plate support 11 is provided with a clamping groove for clamping the storage plate, so that the storage plate can be firmly mounted on the support, and the storage plate can be conveniently inserted and mounted and disassembled through the design of the clamping groove.

[0076] The conductive member 31 is a bent metal sheet, which comprises a first metal sheet 311 embedded in the side of the side cover and a second metal sheet 312 bent from the first metal sheet 311 towards the electric element 3. The conductive connecting member 32 extends from the surface side of the electric element 3, and is in abutment with the first metal sheet 311. The power supply portion 4 is provided with a power supply member 41, which extends from the storage plate support 11 towards the second metal sheet 312. As shown in FIG. 11, the conductive connecting member 32 extends from the surface side of the electric element 3, which can be the length direction of the lamp strip 3 extending along the width direction of the refrigerator. The power supply member 41 extends along the depth direction of the refrigerator.

[0077] The bent metal sheet forms an L shape, and the bent second metal sheet 312 acts as an adapter, so that the conductive connecting member 32 and the conductive member 31 facing in different directions can be electrically connected.

[0078] In another embodiment of the present application, the conductive part 31 is arranged at the rear end of the shelf support 11 and faces the cover part 5. The conductive connecting part 32 is vertically arranged on the surface of the electric element 3 and penetrates through the cover part 5 to abut against the conductive part 31.

[0079] In this embodiment, the conductive part 31 is arranged at the rear end of the shelf support 11 and faces the cover part 5, so that the size of the cover part 5 can be reduced, thereby providing more space for the installation of other components and optimizing the internal structure design of the refrigerator. Moreover, the conductive part 31 is arranged at the rear end of the shelf support 11, so that it becomes a modular component, facilitating installation and disassembly.

[0080] In summary, the present embodiment provides a refrigerator comprising an inner container 1 and a shelf 2 arranged on the inner side of the inner container 1. The inner side of the shelf 2 is provided with a cover part 5 and an electric element 3, such as a light strip. The light strip forms a surrounding lighting layout, providing uniform light coverage, and the light strip enhances the lighting effect, avoiding the traditional top lighting being blocked by the articles. The elastic conductive connecting part 32 presses the electric element 3 and the conductive part 31 tightly through the elastic force, ensuring stable electrical contact and adapting to different installation environments and use conditions. Through the design of the elastic conductive connecting part 32, not only stable electrical contact and efficient power transmission are achieved in the refrigerator, but also the protection of the internal electric element is enhanced, improving the overall reliability and user experience.

[0081] The mechanism of the power supply part in the present embodiment is further described below.

[0082] As shown in FIGS. 12, 13a and 13b, the refrigerator further comprises a power supply part 4. The power supply part 4 is arranged on the outer side of the inner container 1. The inner container 1 is provided with a first through hole, and the power supply part 4 is provided with a power supply part 41. The power supply part 41 is connected to a power source and penetrates through the first through hole to form electrical contact with the electric element 3.

[0083] The conductive part 31 is arranged on the side of the electric element 3, and the power supply part 41 supplies power to the electric element 3 after being in electrical contact with the conductive part 31.

[0084] The power supply part 4 is used to supply power to the electric element 3 in the shelf 2, and is connected to the power supply system of the refrigerator to transmit power to the electric element 3 in the inner container 1 through the power supply part 41. The power supply part 4 is installed on the outer side of the inner container 1, which can effectively avoid the occupation of the internal space and maintain the cleanliness and effective use of the refrigerator interior. At the same time, the external power supply part 4 can facilitate maintenance and repair without interfering with the storage and use of the refrigerator interior.

[0085] The power supply part 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 durable power transmission in the applicable environment of the refrigerator.

[0086] The power supply part 4 further comprises a shell 42. The shell 42 houses the power supply member 41, and is mounted on the outside of the inner container 1. The shell 42 is provided with a second through hole that cooperates with the first through hole. The power supply member 41 passes through the second through hole and the first through hole to form an electrical contact with the electrical element 3.

[0087] The shell 42 can protect and fix the power supply member 41, and ensure the stability and safety of the power transmission. The shell 42 can be fixed on the outer wall of the inner container 1 by adhesion, buckling or other fixing means, to ensure its stability and reliability. The shell 42 is provided with a second through hole that cooperates with the first through hole of the inner container 1, for the power supply member 41 to pass through the shell 42 and the inner container 1 to connect with the internal electrical element 3. In order to prevent cold air leakage and external moisture from entering, a sealing ring or gasket structure can be designed at the connection between the second through hole and the first through hole, to ensure that the through hole still maintains good sealing after the power supply member 41 passes through. The shell 42 houses the power supply member 41, providing physical protection against external environmental factors such as dust, moisture, impact, etc. The shell 42 provides a stable support platform for the power supply member 41, maintaining reliable connection between the power supply member 41 and the electrical element 3.

[0088] The power supply member 41 is a flexible structure that can move in and out along the second through hole and the first through hole.

[0089] The power supply member 41 is designed as a flexible structure, ensuring the stability and reliability of the electrical contact. The refrigerator may be subjected to slight vibrations and displacements during use, and the flexible structure can adapt to these changes through its own expansion and contraction, maintaining stable contact between the power supply member 41 and the electrical element 3, preventing poor contact or disconnection. And when the shelf 2 or the electrical element 3 changes slightly in position, the flexible structure can also automatically adjust its position to ensure that it always maintains good electrical contact. In the internal environment of the refrigerator, temperature changes can cause thermal expansion and contraction of materials. The flexible structure can automatically adapt to these changes, maintaining the stability of the electrical contact and preventing poor contact due to temperature changes.

[0090] The flexible structure can also absorb and buffer external impact forces, preventing damage to the power supply member 41 and the electrical element 3 due to external forces. In particular, during transportation or use, the cushioning effect of the flexible structure can effectively protect the integrity of the electrical connection.

[0091] In addition, since the flexible structure can freely expand and contract within a certain range, it does not need to be precisely aligned during installation, and only needs to roughly insert the power supply member 41 into the through hole, and the flexible structure will automatically adjust to the appropriate position, simplifying the installation process and improving installation efficiency.

[0092] As shown in FIG. 13b and FIG. 14, the power supply part 41 includes elastic device 411 and contact part 412 abutting against the elastic device 411, the elastic device 411 allows the contact part 412 to move along the through hole. The elastic device 411 is a spring, the power supply part 41 is formed with a cavity accommodating the spring. The spring end is connected to the power line, the spring top end extends into the cavity and abuts against the contact part 412.

[0093] In the embodiment, the power supply part 41 is composed of elastic device 411 and contact part 412, the elastic device 411 allows the contact part 412 to move along the first through hole and the second through hole, ensuring the stability and reliability of electrical contact. One end of the spring is connected to the power line. The spring and the power line are fixed by welding or clamping, ensuring that the electric energy can be stably transmitted to the spring. The power line is connected to the power supply system of the refrigerator, providing stable power input.

[0094] The contact part 412 abuts against the top end of the spring, which is made of a metal material with high conductivity, ensuring good conductivity. The shape of the contact part 412 can be cylindrical, flat or other suitable shapes to adapt to different installation environments and use requirements.

[0095] In the embodiment, the contact part 412 is a hollow cylindrical structure, which forms a cavity accommodating the spring. The top end of the spring extends into the cavity and abuts against the contact part 412. The spring presses the contact part 412 towards the electric element 3 by its own elastic force, ensuring that good electrical contact is always maintained.

[0096] In the embodiment, in order to ensure that the power supply part 41 can directly contact the conductive part 31 on the side of the electric element 3, a 2mm margin is required on both sides of the storage plate 21. If the installation position of the storage plate 21 is not accurate, it may appear that one side is 0mm and the other side is 4mm. In order to ensure normal use, the power supply part 41 should at least extend 6mm from the inner container 6 without being pressed by the storage rack 2.

[0097] The elastic device 411 in the power supply part 41 directly contacts the contact part 412. Therefore, the position where the contact part 412 cavity contacts the spring is designed as a flat surface, and the spring is sleeved in the cavity of the contact part 412. In the case that the contact part 412 is not pressed, the spring should at least maintain a state of 10% pre-compression, and the contact part 412 is pressed against the limiting surface in the shell 42. The movement stroke of the contact part 412 is 6mm, and the maximum compression of a normal round spring is 40% of its total height. According to this data, the height of the spring is set to at least 20mm to meet the use requirements.

[0098] Through the above design, the power supply part 41 can provide stable and reliable electrical contact during the actual use of the refrigerator, ensuring the normal operation of the electrical element 3 inside the refrigerator.

[0099] The housing 42 is provided with a guide rib 421. The guide rib 421 is arranged towards the second through hole, and the spring sleeve is arranged on the guide rib 421. The housing 42 is provided with a guide groove 422. The contact piece 412 is arranged in the guide groove 422. The contact piece 412 abuts against the guide groove 422 and moves along the guide groove 422. It can be understood that the contact piece 412 abuts against the inner groove wall of the guide groove 422, so as to guide the movement of the contact piece 412.

[0100] The guide rib 421 is arranged inside the housing 42. The guide rib 421 is an elongated columnar structure, and the cross section can be circular, square or other shapes. The guide rib 421 is arranged towards 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.

[0101] The guide rib 421 guides the spring to move along a predetermined path, ensuring that the spring does not deviate during expansion and contraction. By arranging the guide rib 421, the spring always remains in the correct position when compressed and expanded, avoiding bending or jamming. The guide rib 421 can provide a fixed support, so that the spring is not easy to deform laterally when subjected to force. This can ensure that the elastic force of the spring always acts in the correct direction, ensuring the stability of the electrical contact.

[0102] The guide groove 422 is arranged inside the housing 42 and located on the path of the contact piece 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 piece 412, and the shape of the guide groove 422 is matched with the shape of the contact piece 412. The guide groove 422 provides an accurate movement path, and the contact piece 412 moves along a predetermined trajectory in the guide groove 422, avoiding unstable electrical contact due to path deviation. Through the guidance of the guide groove 422, the contact piece 412 can always remain in the correct position. The design of the guide groove 422 can prevent the contact piece 412 from deviating or jamming during movement.

[0103] As shown in FIGS. 15 and 16, the housing 42 includes a first housing 42a and a second housing 42b that are spliced together. The first housing 42a is provided with a protruding guide rib 421, and the second housing 42b is provided with the guide groove 422.

[0104] The shell 42 is composed of a first shell 42a and a second shell 42b which are spliced together, and presents a semi-closed box structure. The first shell 42a is provided with a protruding guide rib 421. The shape and size of the second shell 42b are set according to the shape of the inner container 1. The second shell 42b matches the shape and size of the inner container 1, so that it can be tightly spliced with the inner container 1. The second shell 42b also presents a semi-closed box structure, and is spliced with the first shell 42a. The second shell 42b is provided with a guide groove 422.

[0105] The first shell 42a and the second shell 42b form a complete protective shell 42 by splicing, providing stable structural support, not only ensuring the overall strength of the shell 42, but also facilitating the installation and disassembly of the shell 42. The closed structure of the shell 42 can effectively protect the internal power supply 41 from external environmental influences such as dust, moisture and mechanical damage. The first shell 42a and the second shell 42b are connected by a buckle structure. The buckle structure includes a protrusion provided on the second shell 42b and a groove structure provided on the first shell 42a. The buckle structure is uniformly distributed around the shell 42 to ensure the connection strength and stability of the entire shell 42.

[0106] The splicing part of the first shell 42a and the second shell 42b can be provided with a sealing ring. The sealing design effectively prevents dust, moisture and other impurities from entering the interior of the shell 42, protecting the internal power supply 41 and other elements from external environmental influences.

[0107] The first shell 42a and the second shell 42b are also provided with opposite matching U-shaped grooves, which form a power line passing hole after splicing.
