Detailed Implementation
[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] This utility model provides a button panel fixing assembly and a range hood. Several embodiments are given below to describe the button panel fixing assembly and range hood provided by this utility model in detail.
[0035] Example 1
[0036] The keypad fixing assembly provided in this embodiment, such as Figures 1 to 5 As shown, it includes a bracket 1 and a cover plate 2; along the first direction, the two ends of the bracket 1 are respectively provided with first sidewalls 11, and the two first sidewalls 11 are respectively provided with first snap-fit members, and the two ends of the cover plate 2 are respectively provided with second snap-fit members; the first snap-fit member of one first sidewall 11 is snapped with the second snap-fit member at one end of the cover plate 2, and the first snap-fit member of the other first sidewall 11 is snapped with the second snap-fit member at the other end of the cover plate 2.
[0037] like Figure 1 As shown, when installing the keypad 3, the keypad 3 is set inside the bracket 1. The bracket 1 limits the keypad 3 in the up, down, back, left, and right directions. The bracket 1 has an opening. After the cover plate 2 is closed on the opening, the first snap-fit of one first sidewall 11 is snapped with the second snap-fit of one end of the cover plate 2, and the first snap-fit of the other first sidewall 11 is snapped with the second snap-fit of the other end of the cover plate 2, so that the cover plate 2 is snapped and fixed to the bracket 1. The cover plate 2 can limit the keypad 3 in the forward direction.
[0038] Forward and backward directions, such as Figure 1 The direction indicated by the middle arrow, both forward and backward, and left and right are as follows: Figure 1 The direction indicated by the middle arrow to the left and right, and the direction of up and down, are as follows: Figure 1 The direction indicated by the middle arrow. The first direction is up and down, the second is left and right, and the third is forward and backward.
[0039] The button board fixing assembly provided in this embodiment uses a first snap-fit component and a second snap-fit component to fix the bracket 1 and the cover plate 2 together. When assembling and repairing the button board 3, there is no need to remove screws, which can reduce the screw removal process, reduce material and labor costs, and avoid the inconvenience of screw removal due to interference problems, thus improving the convenience of fixing the bracket 1 and the cover plate 2.
[0040] The first snap-fit component is fixedly mounted on the first side wall 11, and the second snap-fit component is fixedly mounted on both ends of the cover plate 2.
[0041] In one alternative embodiment, the first snap-fit element can be a spring clip 21, and the second snap-fit element can be a slot 12.
[0042] In another alternative embodiment, the first snap-fit element is a slot 12, and the second snap-fit element is a spring clip 21.
[0043] By using the slot 12 and the spring clip 21 to engage, the bracket 1 and the cover plate 2 are fixed and limited as one unit. The operation is simple and does not require disassembling or assembling screws, which can reduce the screw disassembly and assembly process.
[0044] Further, the slot 12 includes a first slot 121 and a second slot 122; along the second direction, the first slot 121 and the second slot 122 are connected in sequence; along the third direction, one end of the first sidewall 11 has a first edge 111, and the second slot 122 is disposed through the first edge 111; the first slot 121 includes a second sidewall 1211 and a third sidewall 1212 disposed opposite to each other, and the third sidewall 1212 is located on the side of the second sidewall 1211 away from the first edge 111; the end of the second sidewall 1211 near the second slot 122 is provided with a first protrusion 13, and the first protrusion 13 and the third sidewall 1212 are disposed at intervals; the second direction is perpendicular to the third direction, the first direction is perpendicular to the second direction, and the first direction is perpendicular to the third direction.
[0045] like Figure 1 As shown, the second groove 122 and the first edge 111 are connected through and form an opening. When the cover plate 2 is installed, the spring clip 21 enters the second groove 122 through the opening. Press the spring clip 21 on the rear side of the second groove 122 and drive the spring clip 21 to move to the left. After the spring clip 21 passes through the gap between the first protrusion 13 and the third side wall 1212, the spring clip 21 is fully inserted into the first groove 121 located on the left side of the first protrusion 13. At this time, the spring clip 21 is no longer pressed. After the spring clip 21 pops up, the front surface of the spring clip 21 abuts against the second side wall 1211. The left end of the first groove 121 and the first protrusion 13 limit the spring clip 21 in the left and right directions. The front surface of the spring clip 21 abuts against the second side wall 1211, limiting the spring clip 21 in the forward direction. The front surfaces of the spring clips 21 located at the top and bottom of the cover plate 2 abut against the corresponding second side walls 1211, limiting the cover plate 2 in the up and down directions. Thus, when the slot 12 engages with the spring clip 21, it limits the cover plate 2 in the up, down, left, right, and forward directions. The end face of the cover plate 2 facing the button plate 3 contacts the button plate 3. The button plate 3 is embedded in the bracket 1. The bracket 1 limits the button plate 3 in the rear direction, and the button plate 3 limits the cover plate 2 in the rear direction.
[0046] Furthermore, along the second direction, the two ends of the first protrusion 13 have a first end face 131 and a second end face 132 respectively; a third end face 133 is connected between the first end face 131 and the second end face 132; the connection area between the first end face 131 and the third end face 133 is provided with a first chamfer structure 134, and the connection area between the second end face 132 and the third end face 133 is provided with a second chamfer structure 135.
[0047] like Figures 1 to 3 As shown, the area to the left of the first protrusion 13 in the slot 12 is the positioning area, and the remaining areas are positioning areas. When the cover plate 2 is installed, the spring clip 21 enters the guide area through the opening. The spring clip 21 can be guided to the rear side of the second groove 122 along the extension direction of the first chamfered structure 134. At the same time, a force is applied to the left of the spring clip 21, and the spring clip 21 slides between the first protrusion 13 and the third side wall 1212 along the extension direction of the third end face 133. When the spring clip 21 is guided into the second chamfered structure 135, the spring clip springs up, and the spring clip 21 is guided into the positioning area along the extension direction of the second chamfered structure 135. The front surface of the spring clip 21 abuts against the second side wall 1211.
[0048] By setting the first chamfer structure 134 and the second chamfer structure 135, the spring clip 21 can be guided as it passes through the guide area, so that the spring clip 21 can pass through the guide area more smoothly and enter the positioning area.
[0049] Furthermore, the spring clip 21 includes a first spring clip 211; one end of the first spring clip 211 is connected to the cover plate 2; the first spring clip 211 and the cover plate 2 are inclined together, and the first spring clip 211 is inclined toward the outside of the cover plate 2.
[0050] like Figure 1 , Figure 4 and Figure 5As shown, when an external force is applied to the first spring piece 211, the first spring piece 211 can bend backward. During the process of the spring piece buckle 21 connecting with the slot 12, the first spring piece 211 enters the second slot 122 through the opening. Pressing the first spring piece 211 backward and moving it to the left causes the first spring piece 211 to pass through the gap between the first protrusion 13 and the third side wall 1212. After that, the first spring piece 211 is fully inserted into the first slot 121 located to the left of the first protrusion 13. At this time, the first spring piece 211 is no longer pressed. After the first spring piece 211 springs up, the front surface of the first spring piece 211 abuts against the second side wall 1211. The left end of the first groove 121 and the first protrusion 13 limit the first spring piece 211 in the left and right directions. The front surface of the first spring piece 211 abuts against the second side wall 1211, which can limit the spring piece buckle 21 in the forward direction. The front surfaces of the first spring pieces 211 located at the top and bottom of the cover plate 2 abut against the corresponding second side wall 1211, which can limit the cover plate 2 in the up and down directions. Thus, when the slot 12 and the spring piece buckle 21 are engaged, the cover plate 2 is limited in the up, down, left, right and forward directions.
[0051] Furthermore, the spring clip 21 also includes a second spring clip 212; one end of the second spring clip 212 is connected to the end of the first spring clip 211 away from the cover plate 2, the second spring clip 212 and the first spring clip 211 are inclined, and the inclination direction of the second spring clip 212 and the first spring clip 211 is opposite.
[0052] like Figures 4 to 5 As shown, the cover plate 2, the first spring piece 211, and the second spring piece 212 are fixedly connected in sequence. When the spring piece buckle 21 engages with the slot 12, the first spring piece 211 tilts towards the front of the cover plate 2, and the second spring piece 212 tilts towards the rear of the first spring piece 211.
[0053] like Figure 1 , Figure 4 and Figure 5 As shown, during the connection between the spring clip 21 and the slot 12, the first spring clip 211 enters the second slot 122 from the opening. The second spring clip 212 is pressed backward to push the first spring clip 211 backward, simultaneously pushing the second spring clip 212 to the left. This allows the first spring clip 211 to pass through the gap between the first protrusion 13 and the third sidewall 1212, and then fully enters the first slot 121 located to the left of the first protrusion 13. At this point, the second spring clip 212 is no longer pressed, and both spring clips 211 and 212 spring up. The second spring clip 212 can then be easily used to press the spring clip 21.
[0054] Furthermore, along the first direction, the two ends of the cover plate 2 are respectively provided with fourth sidewalls 22; the second snap-fit is provided on the fourth sidewall 22; and the two first sidewalls 11 are sleeved on the outside of the two fourth sidewalls 22.
[0055] One of the fourth sidewalls 22 is disposed opposite to one of the first sidewalls 11, and another fourth sidewall 22 is disposed opposite to another first sidewall 11. The corresponding first sidewalls 11 and second sidewalls 1211 may be in contact with each other or may have a gap.
[0056] Two first sidewalls 11 are fitted onto the outside of two fourth sidewalls 22. In this embodiment, both the first sidewalls 11 and the fourth sidewalls 22 are arranged horizontally. During the process of the spring clip 21 sliding to the left relative to the slot 12, the first sidewalls 11 can guide the fourth sidewalls 22, making the sliding direction of the cover plate 2 more accurate. In addition, the first sidewalls 11 can also limit the fourth sidewalls 22 in a certain way in the upper and lower directions.
[0057] Furthermore, the end face of the cover plate 2 facing the bracket 1 is provided with a second protrusion 25, which is used to contact the keypad 3.
[0058] The end face of the cover plate 2 facing the bracket 1 is the same as the end face of the cover plate 2 facing the key plate 3. The end face of the cover plate 2 facing the bracket 1 is provided with a second protrusion 25. The second protrusion 25 contacts the key plate 3, thereby limiting the cover plate 2 in the rear direction by the key plate 3.
[0059] The number of second protrusions 25 can be one or more. When there are multiple second protrusions 25, the multiple second protrusions 25 are arranged at intervals.
[0060] Furthermore, each of the two first sidewalls 11 is provided with a plurality of first snap-fit members, and the plurality of first snap-fit members on each first sidewall 11 are spaced apart along the second direction; both ends of the cover plate 2 are provided with a plurality of second snap-fit members, and the plurality of second snap-fit members on each end of the cover plate 2 are spaced apart along the second direction; the first direction is perpendicular to the second direction.
[0061] For example, each first sidewall 11 is provided with two first snap-fit members, and the two first snap-fit members on each first sidewall 11 are spaced apart along the second direction. Along the first direction, two second snap-fit members are provided at any end of the cover plate 2, and the two second snap-fit members at any end of the cover plate 2 are spaced apart along the second direction.
[0062] When installing the cover plate 2 onto the bracket 1, align the four spring clips 21 on the cover plate 2 with the openings of the four slots 12 on the bracket 1. Simultaneously, use both hands to apply force to the rear side of the second groove 122 to the four spring clips 21, thereby moving the four spring clips 21 to the left, causing them to deform and slide into the positioning area of the slot 12.
[0063] Releasing the force applied by the left and right hands causes the four spring clips 21 to spring up, and the second protrusion 25 in the middle of the cover plate 2 contacts the button plate 3, thus limiting the button plate 3 in the rear direction. The four spring clips 21 of the cover plate 2 are positioned in the positioning areas of the four slots 12 of the bracket 1, and the bracket 1 limits the cover plate 2 in the up, down, left, right, and front directions. When disassembling and assembling the cover plate 2, the process is reversed as described above.
[0064] The button panel fixing assembly provided in this embodiment uses a snap-fit method to fix the bracket 1 and the cover plate 2, which is convenient for assembly and maintenance, simple to manufacture, and saves material and labor costs. Both the bracket 1 and the cover plate 2 can be switched symmetrically up and down. The deformation of the spring and the limiting function of the bracket 1 enable the cover plate 2 and the bracket 1 to cooperate in fixing the button panel 3.
[0065] Example 2
[0066] The range hood provided in this embodiment includes the button panel fixing assembly provided in Embodiment 1. By using a first and a second snap-fit connector, the bracket 1 and the cover plate 2 are fixedly positioned as one unit. When assembling and repairing the button panel 3, it is not necessary to remove screws, reducing the number of screw removal steps, lowering material and labor costs, and avoiding the inconvenience of screw removal due to interference issues, thus improving the ease of fixing the bracket 1 and the cover plate 2.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
