Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to a buckle assembly part and an air conditioner. Background Art

[0002] At present, the wind sweeping blades on the cabinet are made of PP material. Due to the characteristics of the material itself, the overall rigidity of the parts is poor. When the wind shield blade mounting assembly is connected to the air duct volute, it is connected by a snap-on connection. However, because the aperture of the slot is too large, the snap-on made of PP material is still prone to falling off after being inserted. Summary of the invention

[0003] The problem solved by the invention is how to solve the problem that the buckle is easy to fall off during the assembly process.

[0004] To solve the above problems, the present invention adopts the following technical solutions.

[0005] On the one hand, the present invention provides a snap-on assembly, including an assembly body and a snap-on structure arranged on the assembly body, the snap-on structure including a clamping plate and a hook, the hook being arranged on one side of the clamping plate, and a stop plate being arranged on the other side of the clamping plate, the stop plate being connected to the assembly body, the stop plate and the hook being staggered on both sides of the clamping plate, and the stop plate being used to abut against the inner wall of the clamping slot when the clamping hook is inserted into the clamping slot to prevent the clamping hook from detaching from the clamping slot.

[0006] The snap assembly provided by the present invention, by arranging a stop plate on the card plate, the stop plate is connected to the assembly body, so that the stop plate can play a role of supporting the card plate, thereby improving the rigidity of the snap structure, and at the same time, the stop plate is abutted against the inner wall of the slot during assembly, thereby preventing the card plate from deforming in the slot toward the location of the hook, thereby preventing the hook from shifting and causing it to fall off, and further avoiding the phenomenon of deformation and falling off of the snap structure during the production and assembly process, ensuring that the assembly body is firmly clamped on other components, thereby improving the production and assembly efficiency.

[0007] Furthermore, the stop plate extends from the clamping plate in a direction away from the clamping hook.

[0008] In the buckle assembly provided by the present invention, the stop plate extends from the card plate in a direction away from the card hook, so that a stable triangular structure is formed between the stop plate and the card plate, which facilitates the stop plate to be supported on the inner wall of the card slot after being assembled in place.

[0009] Furthermore, a bayonet structure for matching with the edge of the slot is formed at one end of the stop plate away from the clamping plate.

[0010] The snap-on assembly provided by the present invention matches the snap-on structure formed on the stop plate with the edge of the slot, so that the contact area between the stop plate and the slot is larger, thereby reducing the risk of separation between the stop plate and the inner wall of the slot.

[0011] Furthermore, the bottom side of the hook has a snap-fit ​​surface, the top side of the stop plate is arranged on the hook, the distance between the snap-fit ​​surface and the assembly body is 4.6mm-5mm, and the height of the top side of the stop plate relative to the assembly body is 5.2mm-5.6mm.

[0012] Furthermore, the material of the stop plate is polypropylene.

[0013] Furthermore, the length of the stop plate in the direction away from the hook is 3 mm-3.4 mm.

[0014] Furthermore, a reinforcing rib plate is provided on one side of the clamping plate away from the clamping hook. The reinforcing rib plate is connected to the assembly body and is spaced apart from the stop plate.

[0015] The buckle assembly provided by the present invention enhances the strength of the connection structure between the clamping plate and the assembly body by providing a reinforcing rib plate, thereby preventing the lower part of the clamping plate from deforming relative to the assembly body and causing the clamping hook to fall off.

[0016] Furthermore, the height of one end of the stop plate close to the clamping plate relative to the assembly body is greater than the height of one end of the stop plate away from the clamping plate relative to the assembly body.

[0017] In the buckle assembly provided by the present invention, the height of the stop plate away from the clamping plate is lower than the height close to the clamping plate, so that the stop plate forms a stable triangular structure, improves the structural strength of the stop plate itself, and further improves the structural strength of the overall buckle structure.

[0018] Furthermore, a first guiding bevel is arranged on the stop plate, and the first guiding bevel is inclined from the clamping plate toward a direction away from the clamping hook and close to the assembly body.

[0019] The buckle assembly provided by the present invention has a first guide bevel on the stop plate. By providing the first guide bevel, the buckle structure can be more smoothly installed in the corresponding slot during assembly, so that the structural setting of the stop plate will not hinder the assembly, thereby ensuring the high efficiency of the assembly.

[0020] On the other hand, the present invention provides an air conditioner, including a snap-on assembly, the snap-on assembly including an assembly body and a snap-on structure arranged on the assembly body, the snap-on structure including a clamping plate and a hook, the hook being arranged on one side of the clamping plate, and a stop plate being arranged on the other side of the clamping plate, the stop plate being connected to the assembly body, and a height of the stop plate relative to the assembly body being greater than a distance between the hook and the assembly body, the stop plate being used to abut against an inner wall of the slot when the hook is inserted into the slot to prevent the hook from detaching from the slot.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] First embodiment

[0031] See also Figure 1 and Figure 2 The present embodiment provides a snap-fit ​​assembly 100, the snap-fitting structure of which has high strength, and can prevent the snap-fit ​​from deforming and falling off during the production and assembly process, thereby ensuring the stability of the structure and the assembly efficiency.

[0032] The snap assembly 100 provided in this embodiment includes an assembly body 110 and a snap structure 130 arranged on the assembly body 110, the snap structure 130 includes a clamping plate 150 and a hook 170, the hook 170 is arranged on one side of the clamping plate 150, and a stop plate 190 is arranged on the other side of the clamping plate 150, the stop plate 190 is connected to the assembly body 110, and the stop plate 190 and the hook 170 are staggered and arranged on both sides of the clamping plate, and the stop plate 190 is used to abut against the inner wall of the slot 230 when the hook 170 is inserted into the slot 230 to prevent the hook 170 from detaching from the slot 230. By arranging the stop plate 190 on the card plate 150, the stop plate 190 can play the role of supporting the card plate 150, thereby improving the rigidity of the snap structure 130. At the same time, the stop plate 190 is abutted against the inner wall of the slot 230 during assembly, thereby preventing the card plate 150 from deforming in the slot 230 toward the location of the hook 170, thereby preventing the hook 170 from being displaced and causing it to fall off, thereby preventing the snap structure 130 from deforming and falling off during the production and assembly process, ensuring that the assembly body 110 is firmly clamped on other components, and improving the production and assembly efficiency.

[0033] It should be noted that in this embodiment, the assembly body 110 is snap-connected to the assembly shell 210, wherein the assembly body 110 is a wind sweeping blade, and the assembly shell 210 is an air duct volute, and the wind sweeping blade is assembled on the snap-fit ​​structure 130. Of course, the assembly body 110 here can also be other air conditioning components that need to be snap-connected, such as a front panel, a rear panel, etc., which are not specifically limited here, but all components that need to be snap-connected in the air conditioner 200 are within the protection scope of the present invention.

[0034] It should also be noted that in this embodiment, by providing a stop plate 190, the structure between the snap structure 130 and the slot 230 is made more compact and the gap is smaller, which, in conjunction with the foam part on the duct volute, can achieve the purpose of preventing air leakage at the installation port.

[0035] In this embodiment, the hook 170 and the stop plate 190 are staggered, which means that the height of the stop plate 190 and the inner wall of the slot 230 are set to be lower than the height of the hook 170, so that the point of force of the stop plate 190 on the slot 230 can be staggered with the hook 170 to ensure that the contact point of the stop plate 190 against the inner wall of the slot 230 is not in the deformation direction of the card plate 150 where the hook 170 is located, which facilitates assembly.

[0036] See also Figures 3 to 5The stop plate 190 is disposed in the middle of the card plate 150 and connected to the assembly body 110, and the stop plate 190 extends from the card plate 150 in a direction away from the hook 170. A reinforcing rib plate 191 is also disposed on the side of the card plate 150 away from the hook 170, and the reinforcing rib plate 191 is disposed on the card plate 150 and connected to the assembly body 110, and the reinforcing rib plate 191 extends from the card plate 150 in a direction away from the hook 170.

[0037] In this embodiment, the stop plate 190 is integrally provided on the clamping plate 150 , and the clamping plate 150 and the clamping hook 170 are integrally provided, and are both made of polypropylene (PP) material with good strength and toughness.

[0038] In this embodiment, there are two reinforcing ribs 191, which are arranged on both sides of the stop plate 190 and are arranged parallel to the stop plate 190. By arranging the stop plate 190 and arranging the stop plate 190 in the middle of the clamping plate 150, a stable triangular structure is formed between the stop plate 190 and the clamping plate 150. When the clamping plate 150 is buckled, the force is more uniform, the stability of the clamping plate 150 is improved, and the deformation of the clamping plate 150 is avoided. At the same time, the reinforcing ribs 191 are arranged to improve the rigidity of the clamping structure 130 and avoid deformation of the clamping structure 130.

[0039] It should be noted that in this embodiment, the stopper plate 190 is integrally formed with the clamping plate 150 and the assembly body 110, and the reinforcing rib plate 191 is integrally formed with the clamping plate 150 and the assembly body 110, which further improves the structural strength. At the same time, the clamping plate 150, the assembly body 110 and the stopper plate 190 are all made of PP material, which can be slightly deformed during assembly, making it convenient to install the buckle structure 130 into the card slot 230.

[0040] In this embodiment, a bayonet structure 193 is formed at one end of the stopper plate 190 away from the card plate 150, which is used to match the lower edge of the card slot 230. Specifically, the bayonet structure 193 has a stopper surface, and is abutted against the inner wall of the card slot through the stopper surface, so that the integral structure formed by the stopper plate 190 and the card plate 150 can be interference-fitted in the card slot 230. After being assembled in place, the stopper plate 190 prevents the card plate 150 from being deformed at the hook 170, thereby preventing the hook 170 from being displaced or deformed and falling off.

[0041] The bottom side of the hook 170 has a snap-fit ​​surface 171, the top side of the stop plate 190 is arranged on the card plate 150, and the height of the top side of the stop plate 190 relative to the assembly body 110 is greater than the distance between the snap-fit ​​surface 171 and the assembly body 110, so that the stop plate 190 can be supported at a position higher than the snap-fit ​​surface 171 on the card plate 150, so that when the snap-fit ​​surface 171 of the hook 170 is actually subjected to force, the upper strength of the card plate 150 can be enhanced and is not easy to deform, which further prevents the snap structure 130 from deforming and falling out.

[0042] In this embodiment, the clamping plate 150 is vertically disposed on the assembly body 110 , and a top of the clamping hook 170 is provided with an inclined surface of the clamping hook 170 , so as to facilitate the clamping hook 170 to be installed into the clamping slot 230 .

[0043] It should be noted that in the present embodiment, one side surface of the assembly body 110 has a mounting plane, and the card plate 150 and the stop plate 190 are both arranged on the mounting plane, the snap-fit ​​surface 171 is parallel to the mounting plane, the distance between the snap-fit ​​surface 171 and the assembly body 110, that is, the height of the bottom side of the hook 170 compared to the mounting plane, and the height of the top side of the stop plate 190 relative to the assembly body 110, that is, the height of the stop plate 190 compared to the mounting plane. Since the stop plate 190 and the hook 170 are arranged on both sides of the card plate 150, when the hook 170 is inserted into the slot 230, the structure in the slot 230 will abut against the snap-fit ​​surface 171, so that the hook 170 is subjected to upward pressure, and the stop plate 190 abuts above the snap-fit ​​surface 171, so that the upper part of the card plate 150 is not easy to deform, thereby preventing the hook 170 from falling off from the slot 230.

[0044] In this embodiment, the distance between the snap-fit ​​surface 171 and the assembly body 110 is 4.6 mm-5 mm, and the height of the top side of the stop plate 190 relative to the assembly body 110 is 5.2 mm-5.6 mm. Specifically, the distance between the snap-fit ​​surface 171 and the assembly body 110 is 4.8 mm, and the height of the top side of the stop plate 190 relative to the assembly body 110 is 5.4 mm. Of course, the values ​​listed here are only examples, and the height of the snap-fit ​​surface 171 and the height of the stop plate 190 can be determined according to the structure of the card slot 230, and are not limited to the ranges and values ​​listed in this embodiment.

[0045] In this embodiment, the thickness of the stop plate 190 is 1 mm-1.5 mm. Specifically, the thickness of the stop plate 190 is 1.3 mm. The length of the stop plate 190 in the direction away from the hook 170 is 3 mm-3.4 mm. Specifically, the length of the stop plate 190 in the direction away from the hook 170 is 3.2 mm. In addition, the distance between the end of the stop plate 190 away from the card plate 150 and the side of the card plate 150 with the hook 170 is greater than the width of the card slot 230, so that when the stop plate 190 is inserted into the card slot with the buckle structure 130, the buckle structure 130 and the card slot are interference fit. Since the buckle structure 130 and the stopper plate 190 are interference-fitted in the slot 230, the portion of the stopper plate 190 that contacts the slot 230 receives an extrusion force, and the buckle structure 130 and the stopper plate 190 are both made of polypropylene, so that under the extrusion force, the end of the stopper plate 190 forms a bayonet structure 193. Of course, the thickness and length of the stopper plate 190 are merely examples, and are not limited to the ranges and values ​​given in this embodiment.

[0046] In this embodiment, the top side of the reinforcing rib plate 191 is disposed on the card plate 150, and the height of the top side of the reinforcing rib plate 191 relative to the assembly body 110 is smaller than the distance between the snap-fit ​​surface 171 and the assembly body 110. The height of the top side of the reinforcing rib plate 191 relative to the assembly body 110 is smaller than the distance between the snap-fit ​​surface 171 and the assembly body 110, so that the reinforcing rib plate 191 can support the lower side of the card plate 150, improve the structural strength of the lower side of the card plate 150, and prevent the reinforcing rib plate 191 from affecting the assembly of the snap structure 130.

[0047] In this embodiment, two reinforcing ribs 191 are fixedly connected to the two side edges of the cardboard 150, so as to provide support to the cardboard 150 from the two side edges. The spacing between the reinforcing ribs 191 and the stopper plate 190 is determined by the width of the cardboard 150.

[0048] In this embodiment, the height of the top side of the reinforcing rib plate 191 relative to the assembly body 110 is 3.5 mm-3.9 mm. Specifically, the height of the reinforcing rib plate 191 relative to the mounting plane is 3.7 mm, which is less than the height of the snap-fit ​​surface 171, thereby providing support and reinforcement for the lower part of the card 150. Of course, the height of the reinforcing rib plate 191 here is not limited to the range or value listed in this embodiment, as long as it can meet the height less than the snap-fit ​​surface 171.

[0049] In this embodiment, the thickness of the reinforcing rib plate 191 is 0.7mm-1mm, and the length of the reinforcing rib plate 191 in the direction away from the hook 170 is 2.8mm-3.2mm. Specifically, the thickness of the reinforcing rib plate 191 is 0.8mm, which is less than the thickness of the stop plate 190. At the same time, the length of the reinforcing rib plate 191 in the direction away from the hook 170 is 3mm, which is less than the length of the stop plate 190, so that the reinforcing rib plate 191 plays the role of other auxiliary support when supporting the card plate 150.

[0050] See also Figure 6 The height of the end of the stopper plate 190 close to the card plate 150 relative to the assembly body 110 is greater than the height of the end of the stopper plate 190 away from the card plate 150 relative to the assembly body 110; the height of the end of the reinforcing rib plate 191 close to the card plate 150 relative to the assembly body 110 is greater than the height of the end of the reinforcing rib plate 191 away from the card plate 150 relative to the assembly body 110. The stopper plate 190 and the reinforcing rib plate 191 form a stable triangular structure, which improves the structural strength of the stopper plate 190 and the reinforcing rib plate 191, and further improves the overall structural strength of the buckle structure 130.

[0051] In this embodiment, the stop plate 190 is provided with a first guide bevel 195, which is inclined by the clamping plate 150 in a direction away from the hook 170 and close to the assembly body 110; the reinforcing rib plate 191 is provided with a second guide bevel 197, which is inclined by the clamping plate 150 in a direction away from the hook 170 and close to the assembly body 110. By providing the first guide bevel 195 and the second guide bevel 197, the buckle structure 130 can be more smoothly installed in the corresponding clamping groove 230 during assembly, so that the structural setting of the stop plate 190 will not hinder assembly, ensuring high efficiency of assembly.

[0052] It should be noted that, in this embodiment, the first guide bevel 195 extends from the surface of the card plate 150 to the surface of the assembly body 110, so that the stop plate 190 is a right triangle, and at the same time, the reinforcing rib plate 191 is a horizontally placed trapezoidal structure, so that the second guide bevel 197 and the first guide bevel 195 are not coplanar, and the slope of the first guide bevel 195 is greater than the slope of the second guide bevel 197, so that during assembly, the slot 230 is mainly guided and assembled by the first guide bevel 195, avoiding the difficulty of assembly caused by multiple guide bevels jointly supporting the slot 230.

[0053] To sum up, the snap assembly 100 provided in this embodiment, by setting a stop plate 190 on the card plate 150, the stop plate 190 can play the role of supporting the card plate 150, thereby improving the rigidity of the snap structure 130, and at the same time, the stop plate 190 is abutted against the inner wall of the slot 230 during assembly, and the height of the stop plate 190 is higher than the height of the snap mating surface 171, so that the upper structure strength of the card plate 150 is strengthened, and deformation of the card plate 150 is avoided during snapping, thereby avoiding displacement of the hook 170 and causing it to fall off, thereby avoiding the phenomenon of deformation and falling off of the snap structure 130 during the production and assembly process, ensuring that the assembly body 110 is firmly clamped on other components, and improving the production and assembly efficiency.
