[0033] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this disclosure. Therefore, the drawings and description are to be considered exemplary in nature and not restrictive.

[0034] In related technologies, the opening and closing device includes a main body, a door body, and a hinge mechanism. The hinge mechanism includes a hinge fixing seat and a hinge rotating seat. The hinge fixing seat includes a first hinge main body and a first outer shell connecting part, and the hinge rotating seat includes a second hinge main body and a second outer shell connecting part. The first outer shell connecting part is provided with a first mounting hole, and the second outer shell connecting part is provided with a second mounting hole. Screws pass through the first mounting hole to connect the main body to the hinge fixing seat, and screws pass through the second mounting hole to connect the hinge rotating seat to the door body.

[0035] In one embodiment, to accommodate the hinge mounting base secured by screws, the device body requires pre-drilled screw holes. To prevent leakage of foam or expanding foam, screws are pre-installed in the first mounting holes during the foaming process to seal them. However, the hinge mounting base is not yet installed at this point. After the foaming is complete, the pre-installed screws must be removed to prepare for the hinge mounting base installation. Then, the hinge mounting base is aligned and secured with screws or bolts. In other words, the installation, removal, and reinstallation of screws between the device body and the hinge mounting base makes the installation process cumbersome and reduces the ease of use of the device. Furthermore, the exposed screws, especially in applications like freezers, are susceptible to corrosion and damage from environmental factors, further affecting the overall aesthetics of the device body.

[0036] To address the problem of inconvenient installation of the device body and hinge fixing seat in related technologies, this disclosure provides a device body and opening / closing device for an opening and closing device. The device body of the opening and closing device according to the embodiments of this disclosure is described in detail below with reference to the accompanying drawings.

[0037] Figure 1This is a schematic diagram of the main body of the opening and closing device according to an embodiment of the present disclosure; Figure 2 This is a schematic diagram of the device body and hinge fixing base according to an embodiment of the present disclosure; Figure 3 This is a schematic diagram of the back of the hinge fixing seat according to an embodiment of the present disclosure; Figure 4 This is a schematic diagram of the installation of the device body and hinge mechanism according to an embodiment of the present disclosure; Figure 5 This is an exploded view of the device body and hinge mechanism according to an embodiment of this disclosure. (Refer to...) Figures 1 to 5 As shown, this embodiment of the present disclosure provides a device body for an opening and closing device. Specifically, the device body 1 includes a housing 10 and a first limiting and fixing structure 20. The housing 10 is provided with a first receiving section S1, which is used to mount a fixed hinge seat 30 of the hinge mechanism 3. The first limiting and fixing structure 20 is engaged and assembled with the fixed hinge seat 30. The first limiting and fixing structure 20 includes a first limiting part 20a, a second limiting part 20b, and a third limiting part 20c. The first limiting part 20a cooperates with the fixed hinge seat 30 to limit the horizontal degree of freedom of the fixed hinge seat 30 and its length direction perpendicular to the first receiving section S1. The second limiting part 20b cooperates with the fixed hinge seat 30 to limit the horizontal degree of freedom of the fixed hinge seat 30 and its length direction along the first receiving section S1. The third limiting part 20c cooperates with the fixed hinge seat 30 to limit the vertical degree of freedom of the fixed hinge seat 30.

[0038] For example, the opening and closing device can be a freezer, a door or window (such as a car door), or a folding piece of furniture. For instance, if the opening and closing device is a freezer, the device body 1 can be represented as the freezer cabinet.

[0039] like Figure 2 As shown, exemplarily, the first accommodating region S1 can be a groove provided on the housing 10. For example, the first accommodating region S1 can be a concave shape adapted to the fixed hinge seat 30 of the hinge mechanism 3, so that the fixed hinge seat 30 can be completely accommodated within the first accommodating region S1 after being installed on the housing 10 of the device body 1. The first limiting and fixing structure 20 can be provided within the first accommodating region S1. The hinge fixing seat 30 can include a first hinge body portion 31 and a first outer shell connecting portion 32. The first hinge body portion 31 is cylindrical, and the first outer shell connecting portion 32 forms an accommodating space relative to the bottom of the first hinge body portion 31. In this way, after the hinge fixing seat 30 is fixed to the device body 1, the limiting structure between the hinge fixing seat 30 and the device body 1 can be hidden, thereby improving the overall aesthetics of the fixed hinge seat 30 after it is fixed and further meeting user needs.

[0040] Reference Figure 1 and Figure 2As shown, exemplarily, the first limiting and fixing structure 20 is engaged and assembled with the fixed hinge seat 30. The first limiting part 20a cooperates with the fixed hinge seat 30 to limit the degree of freedom of the fixed hinge seat 30 in the horizontal direction and perpendicular to the length direction of the first receiving interval S1. The first limiting part 20a is disposed in the first receiving interval S1 and is disposed along the length direction of the first receiving interval S1. The fixed hinge seat 30 is provided with a limiting structure corresponding to the first limiting part 20a. The first limiting part 20a and the limiting structure on the fixed hinge seat 30 can be set according to actual usage requirements.

[0041] Reference Figure 1 and Figure 2 As shown, exemplarily, the second limiting part 20b cooperates with the fixed hinge seat 30 to limit the degree of freedom of the fixed hinge seat 30 in the horizontal direction and along the length direction of the first receiving interval S1. The second limiting part 20b is located within the first receiving interval, and the fixed hinge seat 30 is provided with a limiting structure corresponding to the second limiting part 20b. The specific structure of the second limiting part 20b can be set according to actual usage requirements, as long as it can satisfy the requirement of limiting the degree of freedom of the fixed hinge seat in the horizontal direction and along the length direction of the first receiving interval S1.

[0042] Reference Figure 1 and Figure 2 As shown, exemplarily, the third limiting part 20c cooperates with the fixed hinge seat 30 to limit the vertical degree of freedom of the fixed hinge seat 30. The third limiting part 20c is used to limit the vertical degree of freedom, and the fixed hinge seat 30 is provided with a limiting structure corresponding to the third limiting part 20c. The specific structure of the third limiting part 20c can be set according to actual usage requirements.

[0043] In related technologies, a first mounting hole is provided on the first outer shell connecting part of the fixed hinge seat 30, and screws pass through the first mounting hole to connect with the device body. However, in actual installation, to prevent foam leakage, screws need to be pre-installed. After the screws are installed in the first mounting hole, the first mounting hole can be blocked. After the device body completes the foaming process, the screws are removed, and finally, screws are used to fix the hinge seat and the device body. This method makes the installation process of the device body cumbersome and inconvenient to use. Moreover, screws may be exposed, which not only affects the overall aesthetics of the device body, but also the screws may be corroded and damaged by the environment of the freezer. In the opening and closing device of this embodiment, the housing 10 is provided with a first receiving area S1, which is used to install the fixed hinge seat 30 of the hinge mechanism. The first limiting and fixing structure 20 is engaged and assembled with the fixed hinge seat 30. The first limiting and fixing structure 20 includes a first limiting part 20a, a second limiting part 20b, and a third limiting part 20c. The first limiting part 20a cooperates with the fixed hinge seat 30 to limit the horizontal degree of freedom of the fixed hinge seat 30 and its length direction perpendicular to the first receiving interval S1. The second limiting part 20b cooperates with the fixed hinge seat 30 to limit the horizontal degree of freedom of the fixed hinge seat 30 and its length direction along the first receiving interval S1. The third limiting part 20c cooperates with the fixed hinge seat 30 to limit the vertical degree of freedom of the fixed hinge seat 30. The main body of the device is connected to the fixed hinge seat 30 by the first limiting and fixing structure 20, which not only facilitates the installation and disassembly of the main body of the device, but also eliminates the need for fasteners such as screws, further improving the aesthetics of the device body after it is fixed to the hinge seat, and further meeting the user's needs.

[0044] Reference Figures 1 to 3 As shown, in one disclosed embodiment, the housing 10 is provided with a first reinforcing protrusion 11, and the bottom of the fixed hinge seat 30 is provided with a first reinforcing cavity K1. The first reinforcing protrusion 11 can be inserted into the first reinforcing cavity K1, and the first reinforcing protrusion 11 forms a first limiting part 20a.

[0045] For example, the fixed hinge seat 30 includes a first hinge body portion 31 and a first outer shell connecting portion 32. The first hinge body portion 31 has a first receiving cavity along its axial direction. One end of the first outer shell connecting portion 32 is connected to the first hinge body portion 31, and the extending direction of the first outer shell connecting portion 32 is perpendicular to the axial direction of the first hinge body portion 31. A first reinforcing cavity K1 is disposed at the bottom of the first outer shell connecting portion 32. A first reinforcing protrusion 11 on the housing 10 is adapted to the first reinforcing cavity K1 disposed at the bottom of the first outer shell connecting portion 32. When the first outer shell connecting portion 32 of the hinge fixing seat 30 is connected to the device body 1, the first reinforcing protrusion 11 is inserted into the first reinforcing cavity K1. This arrangement can increase the connection strength between the device body 1 and the hinge fixing seat 30, and the first reinforcing protrusion 11 of the device body 1 can also limit the hinge fixing seat through the first reinforcing cavity K1, so that the hinge mechanism does not tilt backward after being subjected to force, achieving an anti-tilting effect, making the hinge mechanism stable and reliable, and preventing it from loosening. The first reinforcing cavity K1 can be formed by the first hinge body, the first outer shell connecting part and the extension plate, and the hole of the first reinforcing cavity K1 can be roughly conical.

[0046] The first limiting part 20a of this embodiment includes a first reinforcing protrusion 11, which can be inserted into the first reinforcing cavity K1. The first reinforcing protrusion 11 can limit the movement of the first reinforcing cavity K1 in the length direction perpendicular to the first accommodating space, thereby limiting the degree of freedom of the hinge fixing seat in the length direction of the first accommodating space by the cooperation of the first reinforcing protrusion 11 and the first reinforcing cavity K1 of the hinge fixing seat 30. Moreover, the cooperation between the first reinforcing protrusion 11 and the first reinforcing cavity K1 of the hinge fixing seat 30 can increase the connection strength between the hinge fixing seat and the main body of the device. The first reinforcing protrusion 11 can also limit the hinge fixing seat through the first reinforcing cavity K1, so that the hinge fixing seat will not tilt backward after being subjected to force, thus achieving an anti-tilting effect.

[0047] Reference Figures 1 to 3 As shown, in one disclosed embodiment, a plurality of third reinforcing protrusions 12 are spaced apart along the length of the first receiving section S1, and a second reinforcing protrusion 33 is spaced apart along the length of the first receiving section S1 at the bottom of the fixed hinge seat 30. Adjacent third reinforcing protrusions 12 form a limiting space, and the second reinforcing protrusion 33 is inserted into the limiting space, forming a second limiting part 20b.

[0048] For example, one end of the second reinforcing protrusion 33 is connected to the first hinge body, and a limiting space is formed between adjacent third reinforcing protrusions 12. The second reinforcing protrusion 33 is inserted into the limiting space formed by the third reinforcing protrusion 22, and the second reinforcing protrusion 33 is limited in the length direction of the first receiving interval by the third reinforcing protrusions 22 on both sides.

[0049] Reference Figure 1 and Figure 2 As shown, in one disclosed embodiment, the housing 10 is further provided with a slot 13, which can be arranged along the length direction perpendicular to the first accommodating interval S1. The bottom of the fixed hinge seat 30 is provided with a buckle plate 34 that engages with the slot 13, and the slot 13 forms a third limiting part 20c.

[0050] For example, the latching plates 34 are located on opposite sides below the first housing connection portion, with the two latching plates 34 arranged opposite each other and perpendicular to the first housing connection portion. The latching plates 34 extend along the long side of the first housing connection portion. The latching plates 34 can be engaged and installed in the latching groove 13, thereby vertically limiting and fixing the hinge fixing seat. It should be noted that the specific structure of the latching plates 34 and the latching groove 13 can be set according to actual usage requirements, and is not limited here.

[0051] Reference Figures 1 to 3 As shown, in one disclosed embodiment, the number of first reinforcing protrusions 11 is at least one, and the at least one first reinforcing protrusion 11 is arranged at intervals along the length direction of the first receiving interval S1. This arrangement can further strengthen the connection strength between the hinge fixing seat and the device body, and enhance the anti-tilting effect. Exemplarily, the number of first reinforcing protrusions 11 is three, and the three first reinforcing protrusions 11 are arranged sequentially along the length direction of the first receiving space. It should be noted that the number, size, and shape of the first reinforcing protrusions 11 can be set according to actual usage requirements, and are not limited here.

[0052] For example, the bottom of the first outer shell connecting portion of the hinge fixing seat is provided with an extension plate. The extension plate is arranged along the length direction of the first accommodating space, and an accommodating interval is formed between the extension plate and the first hinge body. At least one partition plate is connected between the extension plate and the first hinge body, and each partition plate divides the accommodating interval to form a first reinforcing cavity K1. The top end of the extension plate is connected to the first outer shell connecting portion, and the top end of the extension plate is spaced apart from the first hinge body. The outer wall of the extension plate and the first hinge body forms the accommodating interval. The partition plate is disposed within the accommodating interval, and one end of the partition plate is connected to the first hinge body, and the other end of the partition plate is connected to the extension plate, thereby dividing the accommodating interval to form at least two first reinforcing cavities K1. For example, two partition plates divide the accommodating interval to form three first reinforcing cavities. With this arrangement, the extension plate can act as a reinforcing rib to further strengthen the strength of the first outer shell connecting portion, and the partition plate can also act as a reinforcing rib connecting the extension plate and the first hinge body.

[0053] It should be noted that the number of first reinforcing protrusions 11 can be one or more, and the number of partitions can be set according to actual usage requirements. For example, the number of partitions can be one, and the partitions divide the accommodating area into left and right regions. The first reinforcing cavity K1 can also represent the left and right spaces formed by the partitions dividing the accommodating area. That is to say, the first reinforcing cavity K1 can also be understood as a groove-like structure that runs through both sides. The specific shape and structure of the first reinforcing cavity K1 are not limited here; the first reinforcing cavity K1 only needs to be able to accommodate the first reinforcing protrusions and perform the limiting function.

[0054] For example, part of the inner wall of the first reinforcing cavity is formed by the outer wall of the cylindrical first hinge body, so that the aperture of the first reinforcing cavity is generally tapered, which can enhance the reliability of the connection between the first reinforcing cavity and the first reinforcing protrusion.

[0055] Reference Figures 1 to 3 As shown, in one disclosed embodiment, each first reinforcing protrusion 11 is respectively provided with at least two third reinforcing protrusions 12, and one end of the third reinforcing protrusion 12 corresponding to each first reinforcing protrusion 11 is connected to the first reinforcing protrusion 11.

[0056] For example, one end of the third reinforcing protrusion 12 corresponding to the first reinforcing protrusion 11 is connected to the first reinforcing protrusion 11, so that the second reinforcing protrusion can be located within the first reinforcing cavity. The side of the third reinforcing protrusion 12 that contacts the hinge fixing seat is arc-shaped. This arrangement can further enhance the reliability of the limiting and fixing of the second and third reinforcing protrusions, the first reinforcing cavity, and the first reinforcing protrusion.

[0057] The design of the device body in this embodiment is simple, with a hinged fixing seat that is inserted horizontally. During installation, the device body does not need to be lifted; it can be directly inserted. Furthermore, the structural design of the device body allows the hinge mechanism to limit movement in three directions, eliminating the risk of it tilting backward and coming loose.

[0058] Reference Figure 1 and Figure 2 As shown, in one disclosed embodiment, the card slot 13 is located on both sides of the first receiving interval S1. The card slot 13 extends along the length direction perpendicular to the first receiving interval S1. The card slot 13 includes a first side wall 131 away from the first limiting part 20a and a second side wall 132 close to the first limiting part 20a. A first limiting groove 133 is provided on the first side wall 131. A protrusion 341 protruding towards the card slot 13 is provided on the buckle plate 34. The protrusion 341 is limited and fixed with the first limiting groove 133.

[0059] Figure 6 This is a top view of the device body and hinge mechanism according to an embodiment of the present disclosure; Figure 7 for Figure 6A schematic diagram of the AA cross-section. (Refer to...) Figure 6 and Figure 7 As shown, by way of example, the buckle plate 34 may include a first wing plate 342 in the shape of a straight plate. The first wing plate 342 has a protrusion 341 protruding outward toward the outside of the slot 13. A first limiting groove 133 is provided on the first side wall 131 of the slot 13. The protrusion 341 is limited and engaged with the first limiting groove 133.

[0060] Reference Figure 6 and Figure 7 As shown, exemplarily, a protrusion 341 is provided at the end of the first wing plate 342 away from the first outer shell connection portion. That is, the free end of the first wing plate 342 is provided with a protrusion 341, and the free end of the first wing plate can move elastically left and right. The first wing plate 342 can be slightly smaller than the size of the first limiting groove 231. When the first wing plate 342 is inserted into the first limiting groove 133, the free end of the first wing plate 342 can undergo elastic deformation and return to its initial state after entering the first limiting groove 133, thereby making the protrusion 341 and the first limiting groove 133 limit and fix it in a limiting fit.

[0061] Figure 8 This is a top view of the device body and hinge mechanism according to an embodiment of the present disclosure; Figure 9 for Figure 8 A schematic diagram of the BB cross-section. (Refer to...) Figure 8 and Figure 9 As shown, in one disclosed embodiment, the buckle plate 34 includes a U-shaped second wing plate 343, the second wing plate 343 includes a first sub-plate 343a and a second sub-plate 343b, the first sub-plate 343a is connected to the first outer shell connecting part, the second sub-plate 343b is provided with a protrusion 341 protruding outward toward the outside of the slot, the first side wall 131 of the slot 13 is provided with a first limiting groove 133, and the protrusion 341 is limited and engaged with the first limiting groove 133.

[0062] Reference Figure 8 and Figure 9 As shown, exemplarily, the outer side wall of the second sub-plate 343b opposite to the first sub-plate 343a is provided with a protrusion 341, and the second sub-plate 343b can move elastically left and right relative to each other. When the second wing plate 343 is inserted into the first limiting groove 133, the second sub-plate 343b can undergo elastic deformation and return to its initial state after entering the first limiting groove 133, thereby making the protrusion 341 and the first limiting groove 133 limit and fix it in a limiting fit.

[0063] The second wing plate 343 of this embodiment is U-shaped, the slot 13 can be enlarged compared to the straight plate type, and the second sub-plate 343b can be pressed relative to the first sub-plate 343a, thereby facilitating the removal of the main body of the opening and closing device, and also benefiting mold production and processing, reducing processing costs.

[0064] Reference Figure 7 and Figure 9 As shown, in one disclosed embodiment, the first limiting groove 133 includes a first groove bottom 1331 disposed opposite to the second side wall 132 of the slot 13, and an upper groove wall 1332 and a lower groove wall 1333 located on both sides of the first groove bottom 1331. The lower groove wall 1333 is inclined relative to the vertical direction. The protrusion 341 is prismatic in shape, and the prismatic surface of the protrusion 341 is set at an acute angle relative to the vertical direction. The opposing surfaces of the first limiting groove and the protrusion are prismatic surfaces, which further increases the reliability of the limiting engagement and fixation of the protrusion 341 and the first limiting groove 133.

[0065] Reference Figure 7 and Figure 9 As shown, in one disclosed embodiment, a first guide groove 134 is further provided on the first sidewall 131. The first guide groove 134 is located above the first limiting groove 133 and communicates with the mounting surface of the device body 1. The first guide groove 134 is provided with a guide slope that is inclined relative to the vertical direction. The upper side of the sliding surface of the first guide groove 134 is spaced a certain distance from the buckle plate 34. This arrangement allows tools to be inserted into the gap between the upper side of the sliding surface of the first limiting groove 133 and the buckle plate, facilitating the disassembly of the device body and the hinge fixing seat.

[0066] Reference Figure 4 and Figure 5As shown, this disclosure also provides an opening and closing device, including a device body 1, a hinge mechanism 3, and a door body, according to any embodiment of this disclosure. The device body 1 has an opening. The hinge mechanism 3 includes a hinge fixing seat 30, a hinge rotating seat 40, a piston 50, an elastic element 60, and a connecting shaft 70. The hinge fixing seat 30 includes a first hinge main body 31, a first outer shell connecting part 32, and a second limiting and fixing structure 37. The device body 1 and the hinge fixing seat 30 are connected by the first limiting and fixing structure 20 and the second limiting and fixing structure 37. The hinge rotating seat 40 includes a second hinge main body 41 and a second outer shell connecting part 42. The second hinge main body 41 is rotatably connected to the first hinge main body 31. The second hinge main body 41 has a second receiving cavity extending through it along the axial direction. The first hinge main body 31 is provided with a first mating structure, and the second hinge main body 41 is provided with an opening. The piston 50 is disposed in the second receiving cavity. The piston 50 has a second mating structure, and the second mating structure abuts against the first mating structure through the opening. The elastic element 60 is disposed within the second receiving cavity and located at the end of the piston 50 opposite to the second mating structure. The elastic element 60 provides assistance for the abutment state. The connecting shaft 70 passes through the first hinge body 31, the piston 50, the elastic element 60, and the second hinge body 41, so that the first hinge body 31 and the second hinge body 41 are fixed relative to each other axially. The door body is connected to the opening of the device body through the second outer shell connecting part of the hinge rotating seat of the hinge mechanism.

[0067] For example, the hinge fixing seat 30 and the hinge rotating seat 40 are made of polyoxymethylene resin. For instance, both the hinge fixing seat 30 and the hinge rotating seat 40 can be made of polyoxymethylene resin. The specific materials of the hinge fixing seat 30 and the hinge rotating seat 40 are not limited here and can be set according to actual usage requirements.

[0068] In this embodiment, the elastic element 60 provides assistance in the abutment state, mitigating the problem of violent collision between the rotatable panel and the fixed structure caused by the rapid descent of the rotatable panel during door closing, thus improving the user experience. Furthermore, the piston 50 and the elastic element 60 are both disposed within the second receiving cavity of the second hinge body 41, and the first hinge body 31, piston 50, elastic element 60, and second hinge body 41 can be assembled and connected via a connecting shaft 70. This results in a simple hinge, convenient assembly, and reduced space occupied by the hinge mechanism.

[0069] In one disclosed embodiment, the hinge mechanism further includes a limiting structure, which comprises a limiting protrusion and a limiting groove. The limiting protrusion is disposed on the side of the first housing connection portion near the hinge rotating seat, and the limiting groove is disposed on the surface of the second housing connection portion away from the main body of the device. When the door of the opening and closing device is at its maximum opening angle, the limiting protrusion is at least partially engaged and pressed into the limiting groove. This arrangement allows the limiting protrusion to exert a force perpendicular to the axis of the hinge rotating seat on the second housing connection portion, thereby preventing damage to the hinge rotating seat due to tensile forces and improving the reliability and strength of the hinge mechanism.

[0070] In one disclosed embodiment, the top surface of the first mating structure is provided with a first positioning feature, and the top surface of the second mating structure is provided with a second positioning feature. The first and second positioning features cooperate to position the hinge mechanism in its initial state. For example, the first positioning feature can be a circular protrusion, and the second positioning feature can be a circular recess. When the hinge mechanism is in the "chef" position, the circular protrusion and the circular recess cooperate to position the hinge mechanism in its initial state, preventing changes in the initial state due to transportation or other external forces. Furthermore, during installation, the circular protrusion and the circular recess cooperate so that when the hinge mechanism is actually assembled onto the device body, because the included angle between the hinge fixing seat 30 and the hinge rotating seat 40 is greater than or equal to 180° during normal use of the door, the circular protrusion and the circular recess have almost no effect, thus not affecting the normal and smooth use of the hinge mechanism.

[0071] For example, the opening and closing device in this disclosure embodiment can be a freezer, or it can also be other devices that can be opened and closed, such as dishwashers and storage cabinets.

[0072] Reference Figure 2 as well as Figure 4 , Figure 5 As shown, in one disclosed embodiment, a plurality of first reinforcing ribs 35 are provided on the side of the first outer shell connecting portion 32 away from the device body 1. The plurality of first reinforcing ribs 35 extend along the length direction of the first outer shell connecting portion 32 and are spaced apart.

[0073] For example, the first hinge body 31 and the first outer shell connecting part 32 can be injection molded into an integral structure. A plurality of first reinforcing ribs 35 are provided on the side of the first outer shell connecting part 32 facing away from the device body 1. The plurality of first reinforcing ribs 35 extend along the length direction of the first outer shell connecting part 32 and are spaced apart. This arrangement can enhance the strength of the first outer shell connecting part 32.

[0074] In related technologies, the first outer shell connecting part 32 is connected to the device body by screws, and the strength requirement of the first outer shell connecting part 32 is relatively low. However, in this embodiment, the first outer shell connecting part 32 is fixed to the device body 1 by a first limiting and fixing structure and a second limiting and fixing structure, and the strength requirement of the first outer shell connecting part 32 is higher. In this embodiment, by providing a plurality of first reinforcing ribs 35 on the first outer shell connecting part 32, the strength of the first outer shell connecting part 32 can be enhanced, thereby meeting the strength requirement of the first outer shell connecting part 32 being fixed to the device body 1 by the first limiting and fixing structure and the second limiting and fixing structure.

[0075] Reference Figure 2 as well as Figure 4 , Figure 5 As shown, in one disclosed embodiment, a second reinforcing rib 36 is further provided on the side of the first outer shell connecting portion 32 away from the device body 1. The second reinforcing rib 36 is connected between adjacent first reinforcing ribs 35, and the second reinforcing ribs 36 are arranged intersecting each other. This arrangement can further enhance the strength of the first outer shell connecting portion 32, thereby meeting the strength requirement of the first outer shell connecting portion 32 of this disclosed solution to be fixed without screws.

[0076] For example, a first reinforcing rib 35 extends along the length of the first outer shell connection portion 32, and there are multiple first reinforcing ribs 35 spaced apart. A second reinforcing rib 36 is disposed between adjacent first reinforcing ribs 35, and the second reinforcing ribs 36 intersect to form a diamond shape and are connected.
