DETAILED DESCRIPTION

[0050] Embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar components or components having the same or similar functions are denoted by the same or similar reference numerals throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0051] The following disclosure provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and arrangements of specific examples are described below. Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and in itself does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials.

[0052] The chassis part 100 according to the first aspect of the present application is described below with reference to the accompanying drawings.

[0053] As shown in FIGS. 1-13, the chassis part 100 according to the first aspect of the present application includes a chassis 1, and a drain hole 11 is formed on the chassis 1 to drain water accumulated on the chassis 1 through the drain hole 11. A plurality of blocking protrusions 12 are arranged at intervals along the circumference of the drain hole 11 on the inner circumferential wall of the drain hole 11, and the blocking protrusions 12 extend toward the direction close to the central axis of the drain hole 11. That is, the blocking protrusions 12 extend from the inner circumferential wall of the drain hole 11 toward the center of the drain hole 11, so that the blocking protrusions 12 can have a certain blocking effect on objects passing through the drain hole 11, and the plurality of blocking protrusions 12 arranged at intervals along the circumference of the drain hole 11 can improve the blocking effect on objects passing through the drain hole 11.

[0054] Therefore, by providing the plurality of blocking protrusions 12 on the inner circumferential wall of the drain hole 11, the drain hole 11 can block objects passing through the drain hole 11 on the basis of draining, so that the mouse and the like can be prevented from passing through the drain hole 11, thereby improving the mouse-proof performance of the chassis 1. For example, when the chassis 1 is a chassis 1 of a shell of an air conditioner outdoor unit, an electric control box and the like are installed in the shell of the air conditioner outdoor unit, and the blocking protrusions 12 in the drain hole 11 can prevent the mouse from entering the shell to bite and damage the wire harness in the electric control box, thereby avoiding the risk of electric leakage or fire caused by the wire harness breakage.

[0055] According to the chassis part 100 of the first aspect of the present application, by providing the plurality of blocking protrusions 12 on the inner circumferential wall of the drain hole 11, the drain hole 11 can block objects passing through the drain hole 11 on the basis of draining, so that the mouse and the like can be prevented from passing through the drain hole 11, thereby improving the mouse-proof performance of the chassis 1.

[0056] In a specific example, the drain hole 11 is formed at the lowest point of the chassis 1, so that water on the chassis 1 can be better collected and drained out of the drain hole 11, thereby preventing water accumulation on the chassis 1.

[0057] According to some embodiments of the present application, the maximum distance L1 between the free ends of any two blocking protrusions 12 satisfies: L1 < 10 mm. It can be understood that, when the maximum distance between the free ends of any two blocking protrusions 12 is less than 10 mm, the distance between the free ends of any two blocking protrusions 12 is less than 10 mm, that is, the gap between the free ends of any two blocking protrusions 12 is controlled to be less than 10 mm. Thus, the mouse can be prevented from passing through the drain hole 11 through the gap between the free ends of any two blocking protrusions 12, thereby ensuring the mouse-proof effect of the chassis 1. The maximum distance between the free ends of any two blocking protrusions 12 can be 9.9 mm, 9.5 mm, 9 mm, 8.5 mm, 8 mm, 7.5 mm, 7 mm, 6 mm, 5 mm, 4 mm, etc., which is not limited specifically here.

[0058] In some embodiments, the maximum distance between the free ends of any two blocking protrusions 12 refers to the farthest distance between two blocking protrusions 12 opposite in the radial direction of the drain hole 11. For example, when two pairs of blocking protrusions 12 opposite in the radial direction of the drain hole 11 are provided in the drain hole 11, the distance between the free ends of one pair of blocking protrusions 12 is a first distance, the distance between the free ends of the other pair of blocking protrusions 12 is a second distance, and the first distance is greater than the second distance, then the maximum distance between the free ends of any two blocking protrusions 12 is the first distance.

[0059] According to some embodiments of the present application, the interval L2 between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 satisfies: L2 < 10 mm. That is, the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 is controlled within a range less than 10 mm. In this way, it can be better avoided that the mouse passes through the drain hole 11 through the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11, so as to ensure the mouse-proof effect of the chassis 1. Wherein, the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 can be 9.9 mm, 9.5 mm, 9 mm, 8.5 mm, 8 mm, 7.5 mm, 7 mm, 6 mm, 5 mm, 4 mm, etc., which is not limited here.

[0060] It should be noted that here, only the maximum interval between the free ends of any two blocking protrusions 12 and the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 in some cases are exemplified for the purpose of understanding the mouse-proof function of the chassis 1, wherein the maximum interval between the free ends of any two blocking protrusions 12 and the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 can be flexibly adjusted according to actual conditions, such as when it is found that the current maximum interval between the free ends of any two blocking protrusions 12 and the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 still has the problem of mouse passing through, the maximum interval between the free ends of any two blocking protrusions 12 and the interval between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 can be further reduced.

[0061] According to some embodiments of the present application, in the direction away from the center axis of the drain hole 11, the size of the blocking protrusion 12 in the circumferential direction of the drain hole 11 increases. That is, the size of the end of the blocking protrusion 12 connected with the drain hole 11 in the circumferential direction of the drain hole 11 is greater than the size of the free end of the blocking protrusion 12 in the circumferential direction of the drain hole 11. In this way, the connection position of the blocking protrusion 12 and the inner circumferential wall of the drain hole 11 can be better increased to improve the connection stability of the blocking protrusion 12 and the inner circumferential wall of the drain hole 11, and meanwhile, it can be avoided that the interval between two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 at the inner circumferential wall of the drain hole 11 is too large for the mouse to pass through, so as to ensure the mouse-proof effect of the chassis 1.

[0062] According to some embodiments of the present application, the plurality of blocking protrusions 12 are uniformly spaced. Therefore, in the circumferential direction of the drain hole 11, the plurality of blocking protrusions 12 can all have good blocking effect on mice and the like. In addition, it can be understood that, in the process of draining water from the bottom disc 1, the water on the bottom disc 1 flows towards the direction close to the drain hole 11, and then enters the drain hole 11 through the gap between the adjacent two blocking protrusions 12 in the circumferential direction of the drain hole 11 and is drained out. For the convenience of description, the gap between the adjacent two blocking protrusions 12 in the circumferential direction of the drain hole 11 is defined as the first drainage area 111 of the drain hole 11, and the area of the drain hole 11 located on the inner circumferential side of the plurality of blocking protrusions 12 is defined as the second drainage area 112, and is introduced in the description below. Therefore, by uniformly spacing the plurality of blocking protrusions 12 along the circumferential direction of the drain hole 11 on the inner circumferential wall of the drain hole 11, a plurality of first drainage areas 111 uniformly spaced along the circumferential direction of the drain hole 11 can be formed, thereby improving the uniformity of the drainage of the drain hole 11.

[0063] In one specific example, four blocking protrusions 12 uniformly spaced along the circumferential direction of the drain hole 11 are formed on the inner circumferential wall of the drain hole 11, and under the joint action of the four blocking protrusions 12, the projection shape of the drain hole 11 on the horizontal plane is approximately formed as a cross-shaped structure. Therefore, while ensuring the mouse-proof effect of the bottom disc 1, in the process of draining water, the water can be drained through the four first drainage areas 111 of the drain hole 11, and at the same time, the water can be drained through the second drainage area 112 of the drain hole 11, so as to ensure the drainage capacity of the drain hole 11.

[0064] According to some embodiments of the present application, the blocking protrusion 12 is formed with a reinforcing rib 121 extending in the radial direction of the drain hole 11. Therefore, the reinforcing rib 121 can better reinforce the structural strength at the blocking protrusion 12, thereby improving the deformation resistance of the blocking protrusion 12 to improve the blocking strength of the blocking protrusion 12. In one specific example, one end of the reinforcing rib 121 extends to the free end of the blocking protrusion 12, and the other end of the reinforcing rib 121 extends to the portion of the bottom disc 1 located on the outer circumferential side of the drain hole 11, thereby improving the coverage of the reinforcing rib 121, and at the same time, improving the connection strength of the blocking protrusion 12 and the area of the bottom disc 1 located on the outer circumferential side of the drain hole 11, to improve the reinforcing effect of the reinforcing rib 121 on the structural strength of the blocking protrusion 12.

[0065] According to some embodiments of the present application, the reinforcing ribs 121 are formed with flow guide grooves 122 extending along the radial direction of the drain hole 11, and the flow guide grooves 122 extend to the free end of the blocking protrusion 12. That is, the water flow on the outer circumferential side of the drain hole 11 and the water on the upper surface of the blocking protrusion 12 can be guided into the second drainage area 112 of the drain hole 11 through the flow guide grooves 122, so as to relieve the drainage pressure at the first drainage area 111 of the drain hole 11, thereby improving the drainage efficiency of the drain hole 11.

[0066] In some embodiments, the flow guide grooves 122 extend downwardly in a direction close to the central axis of the drain hole 11. Therefore, the water entering the flow guide grooves 122 can flow into the second drainage area 112 under the action of gravity, thereby improving the drainage efficiency of the chassis 1.

[0067] In some embodiments, the size of the flow guide grooves 122 in the circumferential direction of the drain hole 11 increases in a direction close to the central axis of the drain hole 11. That is, the size of one end of the flow guide grooves 122 close to the central axis of the drain hole 11 in the circumferential direction of the drain hole 11 is greater than the size of the other end of the flow guide grooves 122 away from the central axis of the drain hole 11 in the circumferential direction of the drain hole 11, so that the flow guide grooves 122 can play a role in diffusing the water flow and reducing the water pressure, thereby preventing the water flow from being too large in the flow guide grooves 122, and improving the drainage efficiency of the chassis 1.

[0068] According to some embodiments of the present application, the spacing between two adjacent blocking protrusions 12 decreases in a direction close to the central axis of the drain hole 11. That is, the distance between the free ends of two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 is less than the distance between the fixed ends of two adjacent blocking protrusions 12. Therefore, the gap between the free ends of two adjacent blocking protrusions 12 can be avoided to jointly form a larger through space with the second drainage area 112, so as to ensure the rat-proof effect of the chassis 1. In addition, the area of the second drainage area 112 close to the fixed end of the blocking protrusion 12 can have a larger drainage space, thereby improving the drainage efficiency of the drain hole 11.

[0069] According to some embodiments of the present application, the upper surface of the chassis 1 is formed with a drainage groove 13, and the drainage hole 11 is formed on the inner bottom wall of the drainage groove 13. The inner bottom wall of the drainage groove 13 extends downwardly in a direction towards the center of the drainage hole 11. That is, the center of the drainage hole 11 is located at the lowest point of the inner bottom wall of the drainage groove 13, so that the water entering the drainage groove 13 can flow towards the drainage hole 11 under the action of gravity and be discharged. In a specific example, the drainage groove 13 is formed at the lowest point of the chassis 1, so that the water on the chassis 1 can better collect into the drainage groove 13 and eventually be discharged through the drainage hole 11 to prevent water accumulation on the chassis 1.

[0070] According to some embodiments of the present application, the angle α between the inner bottom wall of the drainage groove 13 and the horizontal plane satisfies: α≥2°. That is, the angle of the inner bottom wall of the drainage groove 13 downwardly inclined in a direction towards the center axis of the drainage hole 11 is controlled to be not less than 2°, in other words, the drainage slope of the drainage groove 13 is not less than 2°. It can be understood that the lower the drainage slope, the worse the drainage flow. Therefore, the drainage efficiency of the chassis 1 can be improved. The angle between the inner bottom wall of the drainage groove 13 and the horizontal plane can be 2°, 2.5°, 3°, 3.5°, 4°, 4.5°, 5°, 5.5°, 6°, etc., which is not specifically limited here.

[0071] According to some embodiments of the present application, the chassis component 100 further comprises a drainage nozzle 2 provided at the drainage hole 11 and formed with a water receiving cavity 211 and a drainage passage 221 communicating with the water receiving cavity 211, the water receiving cavity 211 being used for receiving the liquid discharged from the drainage hole 11. That is, the water on the chassis 1 is discharged through the drainage hole 11 into the water receiving cavity 211, and further discharged through the drainage passage 221 of the drainage nozzle 2. The drainage nozzle 2 is convenient to connect with the external pipeline, so that the reliability of the drainage direction of the chassis 1 can be realized. For example, the water inlet end of the drainage pipe can be sleeved on the drainage nozzle 2, and the drainage section of the drainage pipe can be connected to a specified drainage position to prevent the drainage of the chassis 1 from flowing disorderly.

[0072] In some embodiments, the drainage passage 221 extends downwardly in a direction away from the water receiving cavity 211, so that the water entering the drainage passage 221 can quickly flow out under the action of gravity to improve the drainage efficiency of the drainage nozzle 2.

[0073] In a specific example, the drainage group comprises a water receiving part 21 and a drainage part 22. The water receiving part 21 is in the shape of a bowl open upwardly, and the water receiving cavity 211 is formed in the water receiving part 21. The drainage part 22 is connected to the lower end of the water receiving part 21 and located at the central position of the water receiving part 21. The lower end of the elastic connecting arm 231 is connected to the inner bottom wall of the water receiving cavity 211. The drainage part 22 is in the shape of an L-shaped tube, and the drainage passage 221 is formed in the drainage part 22.

[0074] According to some embodiments of the present application, the drain nozzle 2 is formed with an elastic buckle 23, the elastic buckle 23 includes an elastic connecting arm 231 and a clamping protrusion 232, the elastic connecting arm 231 is arranged in the drain hole 11, the upper surface of the bottom disc 1 is formed with a matching protrusion 14, the clamping protrusion 232 is arranged on the side of the connecting arm facing the matching protrusion 14, and the clamping protrusion 232 is located on the upper side of the matching protrusion 14 and abuts against the matching protrusion 14. That is, the elastic buckle 23 is clamped and matched with the matching protrusion 14, and the connection between the drain nozzle 2 and the bottom disc 1 is achieved through the clamped and matched connection of the elastic buckle 23 and the matching protrusion 14, that is, the clamped and connected connection of the drain nozzle 2 and the bottom disc 1. Among them, the clamped and connected structure is simple, and is convenient for assembly and disassembly. Therefore, the assembly efficiency of the drain nozzle 2 and the bottom disc 1 can be improved, and the drain nozzle 2 can be conveniently disassembled for replacement and the like.

[0075] In a specific example, the elastic buckle 23 further includes a reinforcing support rib 233, the reinforcing support rib 233 is arranged on the side of the elastic connecting arm 231 away from the clamping protrusion 232 and is connected with the water receiving part 21, so that the strength of the elastic connecting arm 231 can be improved through the reinforcing support rib 233 to prevent the elastic connecting arm 231 from being damaged, such as whitening and breaking. Among them, the reinforcing support rib 233 can be provided with a plurality of reinforcing support ribs to improve the support strength of the elastic connecting arm 231.

[0076] According to some embodiments of the present application, the matching protrusion 14 is arranged on the outer circumferential side of the drain hole 11. That is, the matching protrusion 14 is also located on the outer circumferential side of the blocking protrusion 12. Therefore, the matching protrusion 14 can be avoided to be formed on the part with weak structural strength such as the blocking protrusion 12, so as to improve the structural stability of the matching protrusion 14, so that the matching protrusion 14 can stably play the role of clamped and matched. In a specific example, the bottom disc 1 is an integral stamping part, and the matching protrusion 14 is formed by stamping the structure at the second drain area 112.

[0077] According to some embodiments of the present application, in the circumferential direction of the drain hole 11, the matching protrusion 14 is arranged between two adjacent blocking protrusions 12. Therefore, the distance between the matching protrusion 14 and the first drain area 111 can be shortened, so as to reduce the matching difficulty of the elastic buckle 23 and the matching protrusion 14. For example, by inserting the elastic buckle 23 into the drain hole 11 through the first drain area 111, the matching protrusion 14 located on the outer side edge of the first drain area 111 can be clamped and matched.

[0078] According to some embodiments of the present application, the matching convex rib 14 comprises a main body portion 141 and two limiting portions 142, the clamping protrusion 232 is clamped on the upper end of the main body portion 141, and the two limiting portions 142 are respectively arranged on the opposite sides of the main body portion 141 in the horizontal direction. The main body portion 141 and the two limiting portions 142 together define a guide space 143 for guiding the elastic buckle 23. That is, the upper end of the elastic buckle 23 is adapted to enter the guide space 143 through the one end of the drain hole 11, and after the upper end of the elastic buckle 23 enters the guide space 143, the insertion direction of the elastic buckle 23 can be better limited by the main body portion 141 and the two limiting portions 142 arranged on the two sides of the main body portion 141, so as to prevent the elastic buckle 23 from deviating to affect the installation accuracy and efficiency of the drain spout 2, that is, to improve the installation accuracy and efficiency of the drain spout 2.

[0079] In a specific example, the width of the elastic connecting arm 231 is not greater than the distance between the two limiting portions 142, so as to ensure that the upper end of the elastic connecting arm 231 extends to the upper side of the two limiting portions 142 to clamp the upper end of the main body portion 141 of the clamping protrusion 232. Specifically, referring to FIGS. 4 and 13, the width of the elastic connecting arm 231 is w1, the width dimension of the upper end opening of the guide space 143 is w2, and the width dimension of the lower end opening of the guide space 143 is w3, wherein w1≤w2≤w3.

[0080] According to some embodiments of the present application, in the up-to-down direction, the distance between the two limiting portions 142 increases. That is, compared with the distance between the two limiting portions 142 away from the one end of the drain hole 11, the distance between the two limiting portions 142 adjacent to the one end of the drain hole 11 is greater. It can be understood that the elastic buckle 23 enters the guide space 143 through the gap between the two limiting portions 142 adjacent to the one end of the drain hole 11. Therefore, the difficulty of the elastic buckle 23 entering the guide space 143 can be reduced, so as to reduce the installation difficulty of the drain spout 2 to improve the installation efficiency.

[0081] According to some embodiments of the present application, the body portion 141 extends obliquely towards the side of the guide space 143 in the up-to-down direction, i.e. towards the direction away from the elastic connecting arm 231. Therefore, the installation of the elastic buckle 23 can be guided well by the side of the body portion 141 towards the guide space 143, specifically, when the upper end of the elastic buckle 23 enters the guide space 143, the clamping protrusion 232 can push the upper end of the elastic connecting arm 231 to deform towards the direction away from the body portion 141 under the guidance of the side of the body portion 141 towards the guide space 143, when the clamping protrusion 232 moves to the upper side of the body portion 141, the body portion 141 can drive the elastic connecting arm 231 to deform elastically by the pushing effect of the clamping protrusion 232, and the connecting protrusion can move towards the direction close to the body portion 141, until the connecting protrusion is clamped with the upper end of the body portion 141.

[0082] According to some embodiments of the present application, the oblique angle β of the side of the body portion 141 towards the guide space 143 relative to the up-to-down direction satisfies 5°≤β≤20°. It can be understood that the greater the oblique angle β of the side of the body portion 141 towards the guide space 143 relative to the up-to-down direction, the better the guiding effect of the body portion 141 on the elastic buckle 23, but the greater the deformation range of the elastic connecting arm 231 during installation; on the contrary, the smaller the oblique angle β of the side of the body portion 141 towards the guide space 143 relative to the up-to-down direction, the worse the guiding effect of the body portion 141 on the elastic buckle 23, but the smaller the deformation range of the elastic connecting arm 231 during installation.

[0083] Therefore, by controlling the oblique angle β of the side of the body portion 141 towards the guide space 143 relative to the up-to-down direction within the range of 5° to 20°, the damage caused by the too large oblique angle β and the too large deformation range of the elastic connecting arm 231 can be avoided, and at the same time, the guiding effect of the body portion 141 on the elastic buckle 23 can be weakened by too small oblique angle β, i.e. the guiding effect of the body portion 141 on the installation of the elastic buckle 23 can be ensured while preventing the fatigue damage of the elastic connecting arm 231. The oblique angle β of the side of the body portion 141 towards the guide space 143 relative to the up-to-down direction can be 5°, 6°, 7°, 9°, 11°, 14°, 16°, 18°, 20°, etc., which is not limited specifically here.

[0084] According to some embodiments of the present application, the thickness t of the elastic connecting arm 231 and the height h1 of the elastic connecting arm 231 satisfy: 4≤h1 / t≤10. Wherein, the thickness of the elastic connecting arm 231 here refers to the size of the elastic connecting arm 231 in the arrangement direction of the elastic connecting arm 231 and the clamping protrusion 232. Wherein, it can be understood that, on the basis of the height of the elastic connecting arm 231 being unchanged, the greater the above ratio, the smaller the thickness of the elastic connecting arm 231, the better the elasticity of the elastic connecting arm 231, but the weaker the structural strength of the elastic connecting arm 231; on the contrary, the smaller the above ratio, the greater the thickness of the elastic connecting arm 231, the worse the elasticity of the elastic connecting arm 231, but the stronger the structural strength of the elastic connecting arm 231. Therefore, by controlling the height of the elastic connecting arm 231 and the thickness of the elastic connecting arm 231 ratio in the range of 4 to 10, the elasticity of the elastic connecting arm 231 can be improved while ensuring the strength of the elastic connecting arm 231, so that the installation difficulty of the elastic buckle 23 can be reduced while preventing the elastic connecting arm 231 from whitening and breaking. Wherein, the height of the elastic connecting arm 231 and the thickness of the elastic connecting arm 231 ratio can be 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, etc. without specific limitation here.

[0085] According to some embodiments of the present application, the height h2 of the clamping protrusion 232 protruding from the elastic connecting arm 231 satisfies: h2≥0.5mm. Thus, it can be avoided that the height of the clamping protrusion 232 protruding from the elastic connecting arm is too small to affect the clamping strength. Wherein, the height of the clamping protrusion 232 protruding from the elastic connecting arm 231 can be 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, etc. without specific limitation here.

[0086] According to some embodiments of the present application, the surface of the clamping protrusion 232 matched with the matching protruding rib 14 is a clamping matched surface 2321, and the included angle γ between the clamping matched surface 2321 and the horizontal plane satisfies: 10°≤γ≤30°. It can be understood that the clamping matched surface 2321 of the clamping protrusion 232 is in abutment with the upper surface of the matching protruding rib 14 to form a clamping match, and the smaller the inclination angle of the clamping matched surface 2321 relative to the horizontal plane, the smaller the included angle between the clamping matched surface 2321 and the upper surface of the matching protruding rib 14, and the closer the clamping matched surface 2321 to the parallel state with the upper surface of the matching protruding rib 14. When the clamping matched surface 2321 is parallel to the upper surface of the matching protruding rib 14, the clamping protrusion 232 will form a surface contact with the matching protruding rib 14 when it moves in the direction of approaching the main body portion 141 under the push of the elastic connecting arm 231, which undoubtedly increases the resistance of the clamping protrusion 232 relative to the matching protruding rib 14. Therefore, the clamping matched surface 2321 is inclined relative to the horizontal plane, which can form a line contact between the clamping matched surface 2321 and the matching protruding rib 14 to reduce the resistance of the clamping protrusion 232 relative to the matching protruding rib 14. Moreover, the larger the inclination angle of the clamping matched surface 2321 relative to the horizontal plane, the larger the included angle between the clamping matched surface 2321 and the upper surface of the matching protruding rib 14, and the closer the clamping matched surface 2321 to the perpendicular state with the upper surface of the matching protruding rib 14. When the clamping matched surface 2321 is perpendicular to the upper surface of the matching protruding rib 14, the clamping protrusion 232 cannot form a clamping match with the matching protruding rib 14.

[0087] Therefore, controlling the included angle between the clamping matched surface 2321 and the horizontal plane in the range of 10° to 30° can reduce the installation difficulty of the elastic buckle 23 while ensuring the clamping stability between the elastic buckle 23 and the matching protruding rib 14. The included angle between the clamping matched surface 2321 and the horizontal plane can be 10°, 12°, 14°, 17°, 20°, 23°, 25°, 28°, 30°, etc., which is not specifically limited here.

[0088] According to some embodiments of the present application, the height dimension h3 of the matching protruding rib 14 is greater than or equal to 2 mm. That is, the height of the matching protruding rib 14 protruding from the upper surface of the chassis 1 is controlled to be not less than 2 mm. Therefore, it can be avoided that the height of the matching protruding rib 14 protruding from the upper surface of the chassis 1 is too small to increase the forming difficulty of the matching protruding rib 14. The height dimension of the matching protruding rib 14 can be 2 mm, 2.1 mm, 2.2 mm, 2.3 mm, 2.4 mm, 2.5 mm, 2.6 mm, 2.7 mm, 2.8 mm, 2.9 mm, 3 mm, etc., which is not specifically limited here.
