Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, and specifically to a switch panel and a switch module. Background Technology

[0002] Switch panels are widely used in electrical equipment and are generally composed of touch parts and panel bodies. At present, when assembling the touch parts and the panel body, most of them first cover the entire panel body with glue, and then press the touch parts onto the glue until the glue solidifies to form an adhesive layer.

[0003] However, in the above method, when the touch piece presses the glue, the glue will flow to the side wall of the panel body to form a residual glue layer. In order to ensure the appearance quality of the switch panel, the residual glue layer needs to be removed after the switch panel is assembled, resulting in low assembly efficiency of the switch panel. In addition, when the touch piece is directly pressed on the glue, the force on the touch piece is uneven, which will make the thickness of the formed adhesive layer uneven, resulting in unstable connection between the touch piece and the panel body. Contents of utility model

[0004] In view of the above, it is necessary to provide a switch panel and a switch module to improve structural stability and assembly efficiency.

[0005] The embodiment of the utility model provides a switch panel, including:

[0009] The rear shell is connected to the frame and is located on the side of the frame away from the dispensing layer. The rear shell is used to carry the control component.

[0010] When assembling the above-mentioned switch panel, glue can be first laid on the dispensing surface, and then the touch part is placed on the bearing surface and pressed appropriately. During this process, a part of the glue squeezed by the touch part will flow into the glue overflow groove. Since the glue overflow groove is arranged around the dispensing surface, the glue flowing into the glue overflow groove will flow in the glue overflow groove to refill between the dispensing surface and the touch part, forming a dispensing layer with a uniform thickness, making the connection between the touch part and the middle frame uniform, which is beneficial to improving the structural stability of the switch panel. In addition, the glue overflow groove can prevent the glue from flowing to the side of the frame body, avoiding the operation of removing residual glue after the switch panel is assembled, thus simplifying the assembly process of the switch panel and being beneficial to improving the assembly efficiency of the switch panel.

[0075] Please see Figure 5 , in some embodiments, the carrying plate 1111 and the side plate 1112 are an integrated structure, which simplifies the processing process of the frame 111 and helps to reduce the processing cost of the frame 111.

[0076] Please see Figure 3In some embodiments, the carrier plate 1111 is provided with an avoidance hole 1111a, which penetrates the carrier plate 1111 and communicates with the accommodating groove 111e, and is used to avoid the electronic components in the control assembly 200, which can reduce the height of the switch panel 100 and is conducive to the miniaturization of the switch panel 100.

[0077] In this embodiment, there are multiple avoidance holes 1111a, and the multiple avoidance holes 1111a are arranged around the limiting hole 111d. The multiple avoidance holes 1111a are used to accommodate multiple relatively large electronic components in the control assembly 200.

[0078] Please see Figures 2 to 4 , the carrier plate 1111 is provided with a limiting hole 111d, the limiting hole 111d passes through the carrier plate 1111 and is connected to the accommodating groove 111e, the touch member 120 is provided with a mounting hole 120a, the mounting hole 120a passes through the touch member 120, the middle frame 110 also includes a limiting body 112, the limiting body 112 is arranged on the glue dispensing surface 111a and is arranged around the limiting hole 111d, the limiting body 112 is inserted into the limiting hole 111d to stop the touch member 120 in a direction parallel to the glue dispensing surface 111a. Among them, the mounting hole 120a and the limiting hole 111d are used to pass through the switch assembly 300, so that the switch assembly 300 is electrically connected to the control assembly 200.

[0079] In this embodiment, a plurality of avoidance holes 1111a are arranged around the limiting body 112.

[0080] Please see Figure 2 and Figure 3 , in some embodiments, the mounting hole 120a includes a central hole 120b and a plurality of positioning holes 120c, the central hole 120b penetrates the touch member 120 along the thickness direction of the touch member 120, and the plurality of positioning holes 120c are all opened on the side wall of the central hole 120b and penetrate the touch member 120 along the thickness direction of the touch member 120. The limiting body 112 includes a main body 1121 and a plurality of limiting parts 1122, the main body 1121 is arranged on the dispensing surface 111a and arranged around the limiting hole 111d, the main body 1121 is inserted into the central hole 120b, the plurality of limiting parts 1122 are all connected to the side of the main body 1121 away from the limiting hole 111d and are arranged at intervals along the circumference of the main body 1121, the plurality of limiting parts 1122 correspond to the plurality of positioning holes 120c one by one, and each limiting part 1122 is inserted into the corresponding positioning hole 120c.

[0081] Therefore, through the above arrangement, the assembly of the touch member 120 and the middle frame 110 can be facilitated, and the plurality of limiting portions 1122 cooperate with the plurality of positioning holes 120c to prevent the touch member 120 from rotating relative to the middle frame 110, thereby facilitating the improvement of the stability of the touch member 120 and the middle frame 110 after assembly.​

[0082] In this embodiment, the main body portion 1121 and the plurality of limiting portions 1122 are of an integral structure, which simplifies the processing process of the limiting body 112 and is beneficial to reducing the processing cost of the limiting body 112.

[0083] In this embodiment, both the mounting hole 120a and the limiting body 112 are centrosymmetric structures to improve the stability after the touch member 120 is assembled with the middle frame 110. Specifically, there are four limiting portions 1122 and four positioning holes 120c. The four limiting portions 1122 are centrosymmetrically arranged with the limiting hole 111d as the center, and the four positioning holes 120c are centrosymmetrically arranged with the center hole 120b as the center.

[0084] Please refer to Figure 6 , in some embodiments, the glue overflow groove 111c includes a bottom wall 111f, a first groove wall 111g and a second groove wall 111h. The two ends of the first groove wall 111g are respectively connected to the glue dispensing surface 111a and the bottom wall 111f. The two ends of the second groove wall 111h are respectively connected to the bearing surface 111b and the bottom wall 111f. The second groove wall 111h and the first groove wall 111g are respectively perpendicular to the bottom wall 111f, and the height of the second groove wall 111h relative to the bottom wall 111f is greater than the height of the first groove wall 111g relative to the bottom wall 111f.

[0085] Therefore, through the above settings, the glue overflow groove 111c is generally U-shaped, has sufficient accommodation space to accommodate the glue flowing out from the glue dispensing surface 111a, and the U-shaped glue overflow groove 111c can prevent the glue dispensing layer 130 from being seen from the side, improving the aesthetics of the switch panel 100. Please refer to Figure 2 and Figure 7 , in some embodiments, the rear shell 140 includes a housing 141 and a locking body 142. The housing 141 is accommodated in the accommodation groove 111e, and the locking body 142 is movably connected to the housing 141 and the bearing plate 1111.

[0086] Therefore, through the locking body 142, the housing 141 and the bearing plate 1111 can form a detachable connection, which is beneficial to the disassembly and assembly of the rear shell 140 and the middle frame 110.

[0087] In some embodiments, the housing 141 is provided with a plurality of countersunk holes 141a, and the locking body 142 includes a plurality of screws 1421. The plurality of screws 1421 correspond to the plurality of countersunk holes 141a one by one. Each screw 1421 passes through the corresponding countersunk hole 141a and is threadedly connected to the bearing plate 1111.

[0088] Therefore, through the above settings, the manufacturing cost of the rear shell 140 can be reduced.

[0089] In this embodiment, the housing 141 is generally in a plate-like structure. There are four countersunk holes 141a and four screws 1421. The four countersunk holes 141a are distributed at the four end corners of the housing 141, which is beneficial to the stability of the connection between the housing 141 and the carrier plate 1111.

[0090] In other embodiments, the rear shell 140 can also be detachably connected to the middle frame 110 by means of snap-fit.

[0091] Please refer to Figure 4 , in some embodiments, the middle frame 110 further includes a snap 113. The snap 113 is connected to the side plate 1112 and accommodated in the accommodation groove 111e. The snap 113 is used to connect to an external component to fix the switch panel 100.

[0092] It should be noted that the snap 113 can be either a convex structure or a groove structure. In this embodiment, the snap 113 is a convex structure. When connecting to an external component, it needs to cooperate with the groove structure on the external component to fix the switch panel 100.

[0093] In some embodiments, there are multiple snaps 113, and the multiple snaps 113 are arranged at equal intervals along the circumferential direction of the side plate 1112, which is beneficial to the stability of the connection between the switch panel 100 and the external component.

[0094] When assembling the above-mentioned switch panel 100, glue can be first laid on the dispensing surface 111a, and then the touch member 120 is placed on the bearing surface 111b and the touch member 120 is appropriately pressed. During this process, a part of the glue squeezed by the touch member 120 will flow into the overflow groove 111c. Since the overflow groove 111c is arranged around the dispensing surface 111a, the glue flowing into the overflow groove 111c will flow in the overflow groove 111c to refill between the dispensing surface 111a and the touch member 120, forming a dispensing layer 130 with a uniform thickness, making the connection between the touch member 120 and the middle frame 110 uniform, which is beneficial to improving the structural stability of the switch panel 100. In addition, the overflow groove 111c can prevent the glue from flowing to the side surface (i.e., the side plate 1112) of the frame 111, avoiding the operation of removing residual glue after the switch panel 100 is assembled, thus simplifying the assembly process of the switch panel 100 and being beneficial to improving the assembly efficiency of the switch panel 100.

[0095] Please refer to Figure 1, in some embodiments, the control component 200 is disposed on the rear housing 140 and located between the housing 141 and the frame 111 of the rear housing 140. Specifically, the control component 200 is received in the receiving groove 111e, and the switch component 300 sequentially passes through the mounting hole 120a and the limiting hole 111d and is electrically connected to the control component 200. Among them, the control component 200 includes a circuit board and electronic components disposed on the circuit board. In the above-mentioned switch module 1000, the thickness of the dispensing layer 130 formed in the switch panel 100 is uniform, so that the connection between the touch member 120 and the middle frame 110 is uniform, which is beneficial to the structural stability of the switch panel 100. In addition, the glue overflow groove 111c in the switch panel 100 can prevent the glue from flowing to the side of the frame 111 when the touch member 120 and the middle frame 110 are assembled, simplifies the assembly process of the switch panel 100, and is beneficial to improving the assembly efficiency of the switch module 1000.
