[0046] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as limiting the present utility model.

[0047] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present utility model 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.

[0048] The chassis component 100 according to an embodiment of the first aspect of the present utility model will be described below with reference to the drawings.

[0049] As Figures 1 to 13 shown, the chassis component 100 according to an embodiment of the first aspect of the present utility model includes: a chassis 1, a drain hole 11 is formed on the chassis 1 to drain the accumulated water on the chassis 1 through the drain hole 11, and a plurality of blocking protrusions 12 are formed on the inner peripheral wall of the drain hole 11 and are arranged at intervals in the circumferential direction of the drain hole 11. The blocking protrusions 12 extend in a direction approaching the central axis of the drain hole 11. That is to say, the blocking protrusions 12 extend from the inner peripheral wall of the drain hole 11 towards the center of the drain hole 11, so that the blocking protrusions 12 can play a certain blocking effect on the objects passing through the drain hole 11, and the plurality of blocking protrusions 12 arranged at intervals in the circumferential direction of the drain hole 11 can improve the blocking effect on the objects passing through the drain hole 11.

[0050] Therefore, by providing a plurality of blocking protrusions 12 on the inner peripheral wall of the drain hole 11, the drain hole 11 can play a blocking role on the objects passing through the drain hole 11 on the basis of draining water, so as to prevent mice and the like from passing through the drain hole 11, thereby improving the anti-mouse performance of the chassis 1. For example, when the chassis 1 is the chassis 1 of the outer shell of an air conditioner outdoor unit, an electric control box and other structures are installed inside the outer shell of the air conditioner outdoor unit. The blocking protrusions 12 in the drain hole 11 can prevent mice from entering the outer shell and biting and damaging the wire harness in the electric control box, so as to avoid the risk of electric leakage or fire caused by the breakage of the wire harness.

[0051] According to the chassis component 100 of the first aspect embodiment of the present utility model, by providing a plurality of blocking protrusions 12 on the inner peripheral wall of the drain hole 11, the drain hole 11 can play a blocking role on the objects passing through the drain hole 11 while draining water, so as to avoid rats and the like from passing through the drain hole 11, thereby improving the rat-proof performance of the chassis 1.

[0052] In a specific example, the drain hole 11 is formed at the lowest point of the chassis 1, so that the water on the chassis 1 can better converge and drain to the drain hole 11 to prevent water accumulation on the chassis 1.

[0053] According to some embodiments of the present utility model, the maximum distance L1 between the free ends of any two blocking protrusions 12 satisfies: L1 < 10 mm. It can be understood that if the maximum distance between the free ends of any two blocking protrusions 12 is less than 10 mm, then 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 within a range less than 10 mm. Thus, it can better prevent rats from passing through the drain hole 11 through the gap between the free ends of any two blocking protrusions 12 to ensure the rat-proof effect of the chassis 1. Among them, 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., and no specific limitation is made here.

[0054] 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 that are opposite to each other in the radial direction of the drain hole 11. For example, when there are two pairs of blocking protrusions 12 that are opposite to each other in the radial direction of the drain hole 11 in the drain hole 11, the distance between the free ends of one pair of blocking protrusions 12 is the first distance, and the distance between the free ends of the other pair of blocking protrusions 12 is the second distance, and when the first distance is greater than the second distance, the maximum distance between the free ends of any two blocking protrusions 12 is the first distance.

[0055] According to some embodiments of the present utility model, in the circumferential direction of the drain hole 11, the interval L2 between any two adjacent blocking protrusions 12 satisfies: L2 < 10 mm. That is, the gap 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. Thus, it can better prevent rats from passing through the drain hole 11 through the gap between any two blocking protrusions 12 in the circumferential direction of the drain hole 11 to ensure the rat-proof effect of the chassis 1. Among them, 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., and no specific limitation is made here.

[0056] It should be noted that here is only an example of the maximum distance between the free ends of any two blocking protrusions 12 and the distance between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 in some cases, so as to facilitate the understanding of the rat-proof function of the chassis 1. Among them, the maximum distance between the free ends of any two blocking protrusions 12 and the distance between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 can be flexibly adjusted according to the actual situation. For example, when it is found that there is still a problem that rats can pass through the maximum distance between the free ends of any two current blocking protrusions 12 and the distance between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11, the maximum distance between the free ends of any two blocking protrusions 12 and the distance between any two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 can be further reduced.

[0057] According to some embodiments of the present invention, in the direction away from the central 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 to say, the size of the end of the blocking protrusion 12 connected to the drain hole 11 in the circumferential direction of the drain hole 11 is larger than the size of the extended end, that is, the free end of the blocking protrusion 12 in the circumferential direction of the drain hole 11. Thus, the connection position between the blocking protrusion 12 and the inner peripheral wall of the drain hole 11 can be better increased to improve the connection stability between the blocking protrusion 12 and the inner peripheral wall of the drain hole 11. At the same time, it can be avoided that the distance between two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 is too large for rats to pass through at the inner peripheral wall of the drain hole 11, so as to ensure the rat-proof effect of the chassis 1.

[0058] According to some embodiments of the present invention, the plurality of blocking protrusions 12 are arranged at equal intervals. Therefore, in the circumferential direction of the drain hole 11, the plurality of blocking protrusions 12 can all have a good blocking effect on rats and the like. In addition, it can be understood that during the drainage process of the chassis 1, the water on the chassis 1 flows towards the direction close to the drain hole 11 and then can enter the drain hole 11 through the gap between two adjacent blocking protrusions 12 in the circumferential direction of the drain hole 11 and be discharged. For the convenience of description, the gap between two adjacent 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 introduced into the following description. Therefore, by arranging the plurality of blocking protrusions 12 at equal intervals along the circumferential direction of the drain hole 11 on the inner peripheral wall of the drain hole 11, a plurality of first drainage areas 111 arranged at equal intervals along the circumferential direction of the drain hole 11 can be formed, thereby improving the drainage uniformity of the drain hole 11.

[0059] In a specific example, four blocking protrusions 12 are formed on the inner peripheral wall of the drain hole 11 and are evenly spaced along the circumferential direction of the drain hole 11. Under the combined action of the four blocking protrusions 12, the shape of the projection of the drain hole 11 on the horizontal plane is approximately formed into a cross-shaped structure. Therefore, while ensuring the anti-rat effect of the chassis 1, during the drainage process, water can be discharged through the four first drainage areas 111 of the drain hole 11, and at the same time, it can pass through the second drainage area 112 of the drain hole 11 to ensure the drainage volume of the drain hole 11.

[0060] According to some embodiments of the present invention, reinforcing ribs 121 extending along the radial direction of the drain hole 11 are formed on the blocking protrusions 12. Therefore, the structural strength at the blocking protrusions 12 can be better reinforced through the reinforcing ribs 121, thereby improving the anti-deformation ability of the blocking protrusions 12 and enhancing the blocking strength of the blocking protrusions 12. In a 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 part of the chassis 1 on the outer peripheral side of the drain hole 11, so as to increase the coverage range of the reinforcing rib 121. At the same time, the connection strength between the blocking protrusion 12 and the part of the chassis 1 in the area on the outer peripheral side of the drain hole 11 can be improved, so as to enhance the strengthening effect of the reinforcing rib 121 on the structural strength of the blocking protrusion 12.

[0061] According to some embodiments of the present invention, diversion grooves 122 extending along the radial direction of the drain hole 11 are formed on the reinforcing ribs 121, and the diversion grooves 122 extend to the free end of the blocking protrusion 12. That is to say, through the diversion grooves 122, the water flow on the outer peripheral 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, thereby relieving the drainage pressure at the first drainage area 111 of the drain hole 11 and improving the drainage efficiency of the drain hole 11.

[0062] In some embodiments, in the direction towards the central axis of the drain hole 11, the diversion grooves 122 extend obliquely downward. Therefore, the water entering the diversion grooves 122 can flow towards the second drainage area 112 under the action of its own weight, so as to improve the drainage efficiency of the chassis 1.

[0063] In some embodiments, in the direction towards the central axis of the drain hole 11, the size of the diversion grooves 122 in the circumferential direction of the drain hole 11 increases. That is, the size of one end of the diversion groove 122 close to the central axis of the drain hole 11 in the circumferential direction of the drain hole 11 is larger than the size of the other end of the diversion groove 122 far from the central axis of the drain hole 11 in the circumferential direction of the drain hole 11. Thus, the diversion grooves 122 can play a role in diffusing the water flow and reducing the water pressure to prevent the water flow from having too much resistance in the diversion grooves 122, thereby improving the drainage efficiency of the chassis 1.

[0064] According to some embodiments of the present utility model, in the direction towards the central axis of the drainage hole 11, the interval between two adjacent blocking protrusions 12 is reduced. That is to say, in the circumferential direction of the drainage hole 11, the distance between the free ends of two adjacent blocking protrusions 12 is less than the distance between the fixed ends of two adjacent blocking protrusions 12. Therefore, it is possible to prevent the gap between the free ends of two adjacent blocking protrusions 12 and the second drainage area 112 from jointly forming a larger passage space through which a mouse can pass, so as to ensure the anti-mouse 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, so as to improve the drainage efficiency of the drainage hole 11.

[0065] According to some embodiments of the present utility model, a drainage groove 13 is formed on the upper surface of the chassis 1, and the drainage hole 11 is formed on the inner bottom wall of the drainage groove 13. In the direction towards the center of the drainage hole 11, the inner bottom wall of the drainage groove 13 extends downward obliquely. That is to say, 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 its own weight 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 be better collected into the drainage groove 13 and finally discharged through the drainage hole 11, so as to prevent water from accumulating on the chassis 1.

[0066] According to some embodiments of the present utility model, the included angle α between the inner bottom wall of the drainage groove 13 and the horizontal plane satisfies: α≥2°. That is, the downward inclination angle of the inner bottom wall of the drainage groove 13 in the direction towards the central axis of the drainage hole 11 is controlled within a range 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 smoothness. Therefore, the drainage efficiency of the chassis 1 can be improved. Among them, the included 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., and no specific limitation is made here.

[0067] According to some embodiments of the present utility model, the chassis component 100 further includes: a drain nozzle 2, the drain nozzle 2 is disposed at the drain hole 11 and is formed with a water receiving cavity 211 and a drain channel 221 communicating with the water receiving cavity 211, and the water receiving cavity 211 is used for receiving the liquid discharged from the drain hole 11. That is to say, the water on the chassis 1 enters the water receiving cavity 211 after being discharged through the drain hole 11, and further discharges from the drain nozzle 2 through the drain channel 221. Among them, it is convenient to connect with an external pipeline through the drain nozzle 2, so as to realize the reliability of the drainage destination of the chassis 1. For example, the water inlet end of the drain pipe can be sleeved on the drain nozzle 2, and the drainage section of the drain pipe can be connected to a designated drainage position to prevent the drainage of the chassis 1 from flowing randomly.

[0068] In some embodiments, in the direction away from the water receiving cavity 211, the drain channel 221 extends obliquely downward, so that the water entering the drain channel 221 can flow out quickly under the action of its own weight, so as to improve the drainage efficiency of the drain nozzle 2.

[0069] In a specific example, the drain group includes a water receiving part 21 and a drainage part 22. The water receiving part 21 is in the shape of an upwardly open bowl, 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 is located at the central position of the water receiving part 21, and 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 a tubular shape in an L shape, and the drain channel 221 is formed in the drainage part 22.

[0070] According to some embodiments of the present utility model, an elastic buckle 23 is formed on the drain nozzle 2. The elastic buckle 23 includes an elastic connecting arm 231 and a clamping protrusion 232. The elastic connecting arm 231 passes through the drain hole 11. A mating rib 14 is formed on the upper surface of the chassis 1. The clamping protrusion 232 is disposed on the side of the connecting arm facing the mating rib 14. The clamping protrusion 232 is located above the mating rib 14 and abuts against the mating rib 14. That is to say, the elastic buckle 23 is clamped and matched with the mating rib 14, and the connection between the drain nozzle 2 and the chassis 1 is realized through the clamping and matching of the elastic buckle 23 and the mating rib 14. That is, the drain nozzle 2 is clamped and connected to the chassis 1. Among them, the structure of the clamping connection is simple, which is convenient for assembly and disassembly. Therefore, the assembly efficiency of the drain nozzle 2 and the chassis 1 can be improved, and it is convenient to remove the drain nozzle 2 for replacement and other operations in the later stage.

[0071] In a specific example, the elastic buckle 23 further includes a reinforcing support rib 233. The reinforcing support rib 233 is disposed on the side of the elastic connecting arm 231 away from the clamping protrusion 232 and is connected to the water receiving part 21. Thus, the strength of the elastic connecting arm 231 can be improved through the reinforcing support rib 233 to prevent damage such as whitening and fracture of the elastic connecting arm 231. Among them, multiple reinforcing support ribs 233 can be provided to improve the support strength for the elastic connecting arm 231.

[0072] According to some embodiments of the present utility model, the mating rib 14 is provided on the outer peripheral side of the drain hole 11. That is to say, the mating rib 14 is also located on the outer peripheral side of the blocking protrusion 12. Therefore, it is possible to avoid the mating rib 14 being formed on a part with relatively weak structural strength such as the blocking protrusion 12, so as to improve the structural stability of the mating rib 14, so that the mating rib 14 can stably play the role of snap-fitting. In a specific example, the chassis 1 is an integrally stamped part, and the mating rib 14 is formed by stamping the structure at the second drainage area 112.

[0073] According to some embodiments of the present utility model, in the circumferential direction of the drain hole 11, the mating rib 14 is provided between two adjacent blocking protrusions 12. Therefore, the distance between the mating rib 14 and the first drainage area 111 can be better shortened, so as to reduce the mating difficulty between the elastic buckle 23 and the mating rib 14. For example, by inserting the elastic buckle 23 into the drain hole 11 through the first drainage area 111, it can be snap-fitted with the mating rib 14 located at the outer edge of the first drainage area 111.

[0074] According to some embodiments of the present utility model, the mating rib 14 includes a main body portion 141 and a limiting portion 142. The latching protrusion 232 is latched at the upper end of the main body portion 141. There are two limiting portions 142 respectively located 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 jointly define a guiding space 143 for guiding the elastic buckle 23. That is to say, the upper end of the elastic buckle 23 is adapted to enter the guiding space 143 through one end of the guiding space 143 adjacent to the drain hole 11. After the upper end of the elastic buckle 23 enters the guiding space 143, the insertion direction of the elastic buckle 23 can be better restricted by the main body portion 141 and the limiting portions 142 located on both sides of the main body portion 141, so as to prevent the elastic buckle 23 from shifting and affecting the installation accuracy and installation efficiency of the drain nozzle 2, that is, the installation accuracy and installation efficiency of the drain nozzle 2 can be improved.

[0075] In a specific example, the width of the elastic connecting arm 231 is not greater than the distance between the two limiting portions 142 to ensure that the upper end of the elastic connecting arm 231 extends above the two limiting portions 142 so that the upper end of the main body portion 141 of the latching protrusion 232 is snap-fitted. Specifically, referring to Figure 4 and Figure 13 , the width of the elastic connecting arm 231 is w1, the width dimension of the upper end opening of the guiding space 143 is w2, and the width dimension of the lower end opening of the guiding space 143 is w3, where w1 ≤ w2 ≤ w3.

[0076] According to some embodiments of the present utility model, in the up-down direction, the distance between the two limiting portions 142 increases. That is to say, compared with the distance between the ends of the two limiting portions 142 away from the drain hole 11, the distance between the ends of the two limiting portions 142 adjacent to the drain hole 11 is greater. It can be understood that the elastic buckle 23 enters the guiding space 143 through the gap between the ends of the two limiting portions 142 adjacent to the drain hole 11. Therefore, the difficulty for the elastic buckle 23 to enter the guiding space 143 can be reduced, thereby reducing the installation difficulty of the drain nozzle 2 and improving the installation efficiency.

[0077] According to some embodiments of the present utility model, in the up-down direction, the side surface of the main body portion 141 facing the guiding space 143 extends obliquely in a direction away from the elastic connecting arm 231. Therefore, the side surface of the main body portion 141 facing the guiding space 143 can provide a good guiding effect for the installation of the elastic buckle 23. Specifically, when the upper end of the elastic buckle 23 enters the guiding space 143, the clamping protrusion 232 can, under the guidance of the side surface of the main body portion 141 facing the guiding space 143, push the upper end of the elastic connecting arm 231 to deform in a direction away from the main body portion 141. When the clamping protrusion 232 moves to the upper side of the main body portion 141, due to the thrust effect of the main body portion 141 acting on the elastic connecting arm 231 through the clamping protrusion 232, the elastic connecting arm 231 restores its elastic deformation and drives the connecting protrusion to move in a direction close to the main body portion 141 until the connecting protrusion forms a clamping fit with the upper end of the main body portion 141.

[0078] According to some embodiments of the present utility model, the inclination angle β of the side surface of the main body portion 141 facing the guiding space 143 with respect to the up-down direction satisfies 5° ≤ β ≤ 20°. It can be understood that the larger the inclination angle of the side surface of the main body portion 141 facing the guiding space 143 with respect to the up-down direction, the better the guiding effect of the main body portion 141 on the elastic buckle 23, but the greater the deformation amplitude of the elastic connecting arm 231 during the installation process; conversely, the smaller the inclination angle of the side surface of the main body portion 141 facing the guiding space 143 with respect to the up-down direction, the worse the guiding effect of the main body portion 141 on the elastic buckle 23, but the smaller the deformation amplitude of the elastic connecting arm 231 during the installation process.

[0079] Therefore, by controlling the inclination angle of the side surface of the main body portion 141 facing the guiding space 143 relative to the vertical direction within the range of 5° to 20°, it is possible to avoid damage caused by an excessively large inclination angle and an excessively large deformation amplitude of the elastic connecting arm 231, and at the same time, it is possible to avoid weakening the guiding effect on the elastic buckle 23 due to an excessively small inclination angle. That is, it is possible to prevent fatigue damage of the elastic connecting arm 231 while ensuring the guiding effect of the main body portion 141 during the installation of the elastic buckle 23. Among them, the inclination angle of the side surface of the main body portion 141 facing the guiding space 143 relative to the vertical direction can be 5°, 6°, 7°, 9°, 11°, 14°, 16°, 18°, 20°, etc., and no specific limitation is made here.

[0080] According to some embodiments of the present invention, the thickness t of the elastic connecting arm 231 and the height h1 of the elastic connecting arm 231 satisfy: 4 ≤ h1 / t ≤ 10. Among them, the thickness of the elastic connecting arm 231 here refers to the dimension of the elastic connecting arm 231 in the arrangement direction of the clamping protrusion 232 and the elastic connecting arm 231. It can be understood that on the basis of the constant height of the elastic connecting arm 231, the larger the above ratio, the smaller the thickness of the elastic connecting arm 231, and 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 larger 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 ratio of the height of the elastic connecting arm 231 to the thickness of the elastic connecting arm 231 within the range of 4 to 10, it is possible to ensure the strength of the elastic connecting arm 231 while improving the elasticity of the elastic connecting arm 231, thereby reducing the installation difficulty of the elastic buckle 23 while preventing the elastic connecting arm 231 from turning white and breaking. Among them, the ratio of the height of the elastic connecting arm 231 to the thickness of the elastic connecting arm 231 can be 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, 10, etc., and no specific limitation is made here.

[0081] According to some embodiments of the present invention, the height h2 of the clamping protrusion 232 protruding from the elastic connecting arm 231 satisfies: h2 ≥ 0.5 mm. Thus, it is possible to avoid the influence of the too small height of the clamping protrusion 232 protruding from the elastic connecting portion on the clamping strength. Among them, the height of the clamping protrusion 232 protruding from the elastic connecting arm 231 can be 0.5 mm, 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm, 0.75 mm, 0.8 mm, etc., and no specific limitation is made here.

[0082] According to some embodiments of the present utility model, the surface of the snap projection 232 that mates with the mating rib 14 is the snap mating surface 2321, and the angle γ between the snap mating surface 2321 and the horizontal plane satisfies: 10° ≤ γ ≤ 30°. It can be understood that the snap mating surface 2321 of the snap projection 232 abuts against the upper surface of the mating rib 14 to form a snap fit. The smaller the inclination angle of the snap mating surface 2321 relative to the horizontal plane, the smaller the angle between the snap mating surface 2321 and the upper surface of the mating projection, and the closer the snap mating surface 2321 is to the state parallel to the upper surface of the mating rib 14. For example, when the snap mating surface 2321 is parallel to the upper surface of the mating rib 14, when the snap projection 232 moves toward the direction close to the main body portion 141 under the push of the elastic connecting arm 231, it will form a surface contact with the mating rib 14, which will undoubtedly increase the resistance of the snap projection 232 moving relative to the mating rib 14. Therefore, by inclinedly arranging the snap mating surface 2321 relative to the horizontal plane, a line contact can be formed between the snap mating surface 2321 and the mating rib 14 to reduce the moving resistance of the snap projection 232 relative to the mating rib 14. Moreover, the larger the inclination angle of the snap mating surface 2321 relative to the horizontal plane, the larger the angle between the snap mating surface 2321 and the upper surface of the mating projection, and the closer the snap mating surface 2321 is to the state perpendicular to the upper surface of the mating rib 14. For example, when the snap mating surface 2321 is perpendicular to the upper surface of the mating rib 14, no snap fit can be formed between the snap projection 232 and the mating rib 14.

[0083] Therefore, by controlling the angle between the snap mating surface 2321 and the horizontal plane within the range of 10° to 30°, the installation difficulty of the elastic snap 23 can be reduced while ensuring the snap stability between the elastic snap 23 and the mating rib 14. Among them, the angle between the snap mating surface 2321 and the horizontal plane can be 10°, 12°, 14°, 17°, 20°, 23°, 25°, 28°, 30°, etc., and no specific limitation is made here.

[0084] According to some embodiments of the present utility model, the height dimension h3 of the mating rib 14 ≥ 2 mm. That is to say, the height of the mating rib 14 protruding from the upper surface of the chassis 1 is controlled within a range not less than 2 mm. Therefore, it is possible to avoid increasing the forming difficulty of the mating rib 14 due to the height of the mating rib 14 protruding from the upper surface of the chassis 1 being too small. Among them, the height dimension of the mating 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., and no specific limitation is made here.
