Description

Technical Field

[0001] The invention relates to the field of household appliances, in particular to a computer board mounting assembly and a household appliance having the same. Background Art

[0002] With the improvement of people's consumption level, various types of household appliances emerge in an endless stream. Household appliances are favored by the majority of users because of their powerful functions and convenient use. In addition, household appliances can liberate people from heavy, trivial and time-consuming housework, creating a more comfortable and beautiful living and working environment for human beings, which is more conducive to physical and mental health.

[0003] At present, a computer board is usually provided in a household appliance so that the household appliance can be automatically controlled by the computer board. Most existing computer boards include a housing and a mainboard arranged in the housing. When the components on the mainboard are damaged, the household appliance may not be used normally, and the computer board needs to be disassembled and installed for maintenance. Most existing computer boards use fasteners such as bolts or screws to fix the housing to the base of the household appliance. When disassembling and assembling the computer board, since the computer board is mostly arranged inside the household appliance, and some are arranged at the bottom or side of the household appliance and other operating parts, it is extremely inconvenient to disassemble and assemble the computer board.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Summary of the invention

[0005] In order to solve the technical problem of inconvenient assembly and disassembly of computer boards in the prior art, the present invention provides a computer board mounting assembly. The computer board mounting assembly comprises: a mounting bracket, on which a mounting slot opening upward is provided, the mounting slot having a first side and a second side opposite to each other, a first vertical portion is provided on the first side, a second vertical portion is provided on the second side, and a vertical limiting slot and a horizontal limiting slot spaced from each other are provided on at least one of the first vertical portion and the second vertical portion; and a computer board, on which a vertical limiting protrusion and a horizontal limiting protrusion are provided, and the computer board is configured to be obliquely inserted into the mounting slot and the vertical limiting protrusion is inserted into the corresponding vertical limiting slot by flipping the computer board vertically, and the horizontal limiting protrusion is inserted into the corresponding horizontal limiting slot.

[0006] The computer board mounting assembly of the present invention comprises a mounting bracket and a computer board. A mounting groove with an opening facing upward is provided on the mounting bracket. The setting of the mounting groove can conveniently fix the computer board on the mounting bracket. The mounting groove has a first side and a second side opposite to each other. A first vertical portion is provided on the first side, and a second vertical portion is provided on the second side. The setting of the first vertical portion and the second vertical portion can facilitate the fixing of both sides of the computer board. A vertical limiting groove and a transverse limiting groove spaced apart from each other are provided on at least one of the first vertical portion and the second vertical portion, and a vertical limiting protrusion and a transverse limiting protrusion are provided on the computer board. The computer board is configured to be obliquely inserted into the mounting groove and the vertical limiting protrusion is inserted into the corresponding vertical limiting groove by flipping the computer board toward the vertical direction, and the transverse limiting protrusion is inserted into the corresponding transverse limiting groove. Therefore, when installing the computer board mounting assembly of the present invention, it is only necessary to obliquely insert the computer board into the mounting groove, and then flip the computer board toward the vertical direction, so that the limiting installation of the computer board can be realized by the cooperation of the limiting protrusion and the limiting groove, and the operation is simple and convenient. In addition, the vertical limiting groove and the vertical limiting protrusion can limit the vertical displacement of the computer board, and the horizontal limiting groove and the horizontal limiting protrusion can limit the horizontal displacement of the computer board, thereby stably fixing the computer board in the installation groove.

[0007] In the preferred technical solution of the computer board mounting assembly, the transverse limiting protrusion includes an L-shaped body and a wedge-shaped stopper formed on the L-shaped body, and the wedge-shaped stopper is configured to be inserted into the transverse limiting groove. The setting of the L-shaped body allows it to be appropriately deformed during disassembly and assembly, so that the wedge-shaped stopper can be more conveniently inserted into or removed from the transverse limiting groove. In addition, the setting of the wedge-shaped stopper can be conveniently matched with the transverse limiting groove to form a limiting fit.

[0033] Figure 1 It is a structural schematic diagram of an embodiment of a computer board of a computer board mounting assembly of the present invention in a tilted state; Figure 2 It is a structural schematic diagram of an embodiment of a computer board of a computer board mounting assembly of the present invention in an installed state; Figure 3 yes Figure 2 The A part of the embodiment of the computer board installation assembly of the present invention is a partial enlarged view of the computer board in the installation state. Figure 1-Figure 3 As shown, in one or more embodiments, the computer board mounting assembly 2 of the present invention includes a mounting bracket 20 and a computer board 30 mounted on the mounting bracket 20 .

[0034] Figure 4 1 is a schematic diagram of the structure of an embodiment of the mounting bracket of the computer board mounting assembly of the present invention. Figure 1-Figure 4 As shown, in one or more embodiments, the mounting bracket 20 can be made of a suitable resin material (such as PE, PVC, etc.) and integrally formed by an injection molding process to simplify the manufacturing process. A mounting groove 21 with an opening upward is formed on the mounting bracket 20. The mounting groove 21 has a first side 21a and a second side 21b opposite to each other. Figure 1In the orientation shown, the first side 21a is located on the left side and the second side 21b is located on the right side. Alternatively, it can also be set that the first side 21a is located on the right side and the second side 21b is located on the left side. A first vertical portion 22 is provided on the first side 21a, and a second vertical portion 23 is provided on the second side 21b. The first vertical portion 22 is provided with a vertical limit groove 221 and a transverse limit groove 222 spaced from each other. The vertical limit groove 221 and the transverse limit groove 222 are spaced from each other in the height direction of the first vertical portion 22. The transverse limit groove 222 is located above the vertical limit groove 221. Alternatively, it can also be set that the vertical limit groove 221 is located above the transverse limit groove 222. The vertical limit groove 221 is set to allow the vertical limit protrusion 33 formed on the computer board 20 to be inserted therein, thereby limiting the vertical displacement of the computer board 30. The transverse limit groove 222 is provided to allow the transverse limit protrusion 34 formed on the computer board 30 to be inserted therein, thereby limiting the transverse displacement of the computer board 30. Alternatively, the vertical limit groove 221 and the transverse limit groove 222 may also be formed on the second vertical portion 23. Alternatively, the vertical limit groove 221 and the transverse limit groove 222 may also be provided on both the first vertical portion 22 and the second vertical portion 23. It should be noted that when installing the computer board 20, the computer board 30 is first configured to be inserted into the installation slot 21 at an angle (such as Figure 1 As shown in FIG. 2 ), the bottom of the computer board 30 abuts against the bottom of the installation slot 21. Then the computer board 30 is flipped vertically (i.e., flipped backwards), the vertical limiting protrusion 33 is inserted into the corresponding vertical limiting slot 221, and the horizontal limiting protrusion 34 is inserted into the corresponding horizontal limiting slot 222, so that the computer board 30 is vertically installed in the installation slot 21 (as shown in FIG. 2 ). Figure 2 shown).

[0035] Continue to see Figure 3In one or more embodiments, the transverse limiting groove 222 is surrounded by a first vertical wall 2221 and a second vertical wall 2222 formed on the first side 21a. Specifically, the first vertical wall 2221 and the second vertical wall 2222 both extend substantially vertically and extend toward the second side 21b. The first vertical wall 2221 and the second vertical wall 2222 are spaced apart from each other along the depth direction of the first vertical portion 22. The first vertical wall 2221 is close to the outside of the mounting bracket 20, and the second vertical wall 2222 is close to the inside of the mounting bracket 20. In one or more embodiments, a guide slope 22211 matching the wedge-shaped stopper 342 of the transverse limiting protrusion 34 is also formed on the first vertical wall 2221. Specifically, the guide slope 22211 is an oblique cut surface formed on the first vertical wall 2221 near the outside of the mounting bracket 20. The provision of the guide slope 22211 allows the transverse limiting protrusion 34 to be conveniently inserted into the transverse limiting groove 222. In one or more embodiments, the vertical limiting groove 221 is a groove that is recessed inward from the outside of the first vertical portion 22. The provision of the groove can facilitate the vertical limiting protrusion 33 to be conveniently inserted into the vertical limiting groove 221 when the computer board 30 is flipped vertically.

[0036] Continue to see Figure 3 In one or more embodiments, the first vertical portion 22 further includes a first abutment wall 223. The first abutment wall 223 extends from the corresponding first side 21a into the mounting groove 21 (i.e., toward the second side 21b). The first abutment wall 223 is located on the inner side of the mounting bracket 20. When the computer board 30 is vertically installed in the mounting groove 21, the rear side of the computer board 30 abuts against the first abutment wall 223. In one or more embodiments, the first abutment wall 223 includes a straight section 2231 and an arc section 2232 connected to each other. The straight section 2231 is located on a side of the second vertical wall 2222 away from the first vertical wall 2221 and is spaced apart from the second vertical wall 2222. The straight section 2231 extends from the first side 21a into the mounting groove 21 until it is flush with the second vertical wall 2222. The arc section 2232 extends from the end of the straight section 2231 toward the inner side of the mounting bracket 20 and has a C-shaped structure with an opening toward the mounting slot 21. The arrangement of the straight section 2231 and the arc section 2232 enables the computer board 30 to abut against the first abutting wall 223 better.

[0037] like Figure 1-Figure 4As shown, in one or more embodiments, the second vertical portion 23 is a vertical wall located on the second side 21b of the mounting slot 21.

The fastener includes but is not limited to screws, bolts, etc. In one or more embodiments, the second vertical portion 23 also includes a second abutment wall 232 extending from the second side 21b to the inside of the mounting slot 21. The second abutment wall 232 is located on the inner side of the mounting bracket 20, so that when the computer board 30 is installed in the mounting slot 21, the rear side of the computer board 30 abuts against the second abutment wall 232, thereby more stably defining the computer board 30.

[0038] Continue to see Figure 4 In one or more embodiments, a front stop wall 24 is further formed on the mounting bracket 20. The front stop wall 24 is located outside the mounting bracket 20 and extends vertically upward from the lower portion of the mounting slot 21. The front stop wall 24 extends from the first vertical portion 22 to the second vertical portion 23. The provision of the front stop wall 24 can prevent the computer board 30 from falling out of the mounting slot 21 and can also enhance the structural strength of the mounting bracket 20.

The provision of the positioning holes 3221 allows the positioning protrusions 3121 to be inserted therein, so as to facilitate the positioning of the cover body 32 when it is installed on the chassis 31. Alternatively, the number of the positioning protrusions 3121 and the positioning holes 3221 can be set to other numbers more or less than 2, such as 1, 3, etc.

[0042] Continue to see Figure 6 and Figure 7In one or more embodiments, a clamping hole 3131 is provided on the side 313 of the chassis 31. Specifically, a clamping lug 3132 is formed on the chassis 31, and the clamping hole 3131 is formed on the clamping lug 3132. The clamping lug 3132 extends from the side 313 toward the side away from the chassis body 311. Alternatively, the clamping hole 3131 can also be directly formed on the side 313. A clamping protrusion 3231 matching the clamping hole 3131 is provided on the side wall 323 of the cover body 32. The clamping protrusion 3231 extends from the side wall 323 toward the side of the side 313. When in the assembled state, the clamping protrusion 3231 is inserted into the corresponding clamping hole 3131 to fix the cover body 32 on the chassis 31. In one or more embodiments, the clamping protrusion 3231 includes two protrusions spaced from each other along the length direction of the side wall 323. Reinforcing ribs 3232 are also provided on both sides of the clamping protrusion 3231. The provision of the reinforcing ribs 3232 can strengthen the structural strength of the clamping protrusion 3231. It should be noted that the clamping protrusion 3231 can be formed on the side wall 323 located on the left side, or on the side wall 323 located on the right side, or on both side walls 323. When the cover body 32 is covered on the chassis 31, the positioning protrusion 3121 can be first inserted obliquely into the corresponding positioning hole 3221, and the clamping protrusion 3231 can be inserted into the corresponding clamping hole 3131 by turning the chassis 31 vertically.

In one or more embodiments, the vertical limiting protrusion 33 has a U-shaped body 331 with an opening toward the outside of the mounting bracket 20. The provision of the U-shaped body 331 can improve the structural strength of the vertical limiting protrusion 33, and can also increase the abutment area between the vertical limiting protrusion 33 and the vertical limiting groove 221.

[0046] Continue to see Figure 1-Figure 5 In one or more embodiments, the transverse limiting protrusion 34 includes an L-shaped body 341 and a wedge-shaped stopper 342 formed on the L-shaped body 341. The L-shaped body 341 includes a transverse section 3411 and a vertical section 3412. The transverse section 3411 extends from the side wall 323 of the cover body 32 on the left side to the side away from the cover body 32. The transverse section 3411 is used to fix the transverse limiting protrusion 34 on the cover body 32. The vertical section 3412 extends from the end of the transverse section 3411 to the outside of the mounting bracket 20. The provision of the vertical section 3412 can facilitate the insertion of the wedge-shaped stopper 342 into the transverse limiting groove 222. The wedge-shaped stopper 342 is formed on one side of the vertical section 3412 close to the transverse limiting groove 222. The width of the wedge-shaped stopper 342 gradually increases in the direction toward the outside of the mounting bracket 20 to form a protrusion with an inclined surface. The inclined surface of the wedge-shaped stopper 342 can match the guiding inclined surface 22211 and be inserted into the transverse limiting groove 222 along the guiding inclined surface 22211 .
