[0019] The present invention will now be further described with reference to the accompanying drawings.
[0020] The self-resetting switch mechanism of this utility model, such as Figures 1 to 3 As shown, it includes an inner button 43, a toggle block 44, a switch lever 49, and a return spring 46 for applying a forward pushing force to the inner button 43. The inner button 43 is slidably arranged back and forth. The front end of the return spring 46 is connected to the inner button 43, and the rear end of the toggle block 44 is driven to connect to the switch lever 49. Figure 2 As shown, the inner button 43 has a hinge limiting hole 432, and the front end of the toggle block 44 has a hinge shaft head 442. For force balance, the toggle block 44 has the aforementioned hinge shaft head 442 on both its left and right sides. Figure 2 Combination Figure 3 As shown, the hinge head 442 is movably disposed within the corresponding hinge limiting hole 432. That is, the inner diameter of the hinge limiting hole 432 is slightly larger than the diameter of the hinge head 442, allowing the hinge head 442 to move radially within the hinge limiting hole 432 to a certain extent. More specifically, the inner diameter of the hinge limiting hole 432 is 0.2 to 0.3 mm larger than the diameter of the hinge head 442. Because the connection between the toggle block 44 and the inner button 43 is an inner and outer circular connection, the toggle block 44 has better micro-movement performance relative to the inner button 43. Figure 2 As shown, the front end of the lever 44 has a lever front end face 4402, and the upper and lower ends of the lever front end face 4402 have push corner portions 4403 respectively. Specifically, the push corner portions 4403 are the connection parts between the lever front end face 4402 and the upper and lower sides of the lever 44, and the lever front end face 4402 can be perpendicular to the upper and lower sides of the lever 44. Figure 2 As shown, a groove 434 is formed on the front side of the inner button 43, as... Figure 1 As shown, a pressure plate positioning block 48 and a spring pressure plate 441 are adapted to fit inside the groove 434. The upper and lower ends of the spring pressure plate 441 are clamped between the pressure plate positioning block 48 and the bottom of the groove 434. The groove 434 positions the spring pressure plate 441 in the left-right direction. The middle part of the spring pressure plate 441 (in the up-down direction) is located on the front side of the front end face 4402 of the push block, and the pushing corner part 4403 is attached to and connected to the spring pressure plate 441. Figure 1The upper and lower push angle portions 4403 are symmetrically distributed on both sides of the hinged shaft head 442.
[0021] As shown in Figure 1 and Figure 4 When the inner button 43 is pressed backward, the inner button 43 moves backward, and the reset spring 46 is elastically compressed and deformed. Since the hinged shaft head 442 is movably arranged in the corresponding hinged limiting hole 432, the inner button 43 can drive the push block 44 to move backward. At this time, the switch push arm 49 is in an inclined state relative to the horizontal plane, so that the front upper end of the switch push arm 49 is located in front of the front lower end of the switch push arm 49, for example. The rear end of the push block 44 is first in contact with the front upper end of the switch push arm 49, and the swing center of the push block 44 is arranged at about the same height as the swing center of the switch push arm 49. Therefore, the backward pushing force of the inner button 43 on the switch push arm 49 generates a clockwise moment on the switch push arm 49, for example, so that the rear end of the switch push arm 49 swings downward, and the switch push arm 49 drives the switch switching assembly 45 to realize the switch switching action. Since the switch switching assembly 45 is a prior art and is not the focus of the present application, it will not be described in detail here. When the inner button 43 is released, the elastic restoring force of the reset spring 46 pushes the inner button 43 forward, so that the inner button 43 is reset. Specifically, the upper part of the inner button 43 and the lower part of the inner button 43 are each provided with a reset spring 46, which is beneficial to balance the upward and downward forces on the inner button 43 and facilitate the flexible resetting of the inner button 43. As can be seen from the foregoing, the push block 44 actually drives the switch push arm 49 to swing to realize the switch action. Therefore, when the push block 44 and the switch push arm 49 are in contact with each other (as shown in Figure 1 , specifically, the fork leg 4401 of the push block 44 contacts and pushes the pushed inner step 491 of the switch push arm 49), the hinged shaft head 442 can move in the hinged limiting hole 432, that is, the push block 44 can move and give way to avoid rigid interference between the push block 44 and the switch push arm 49, which hinders the movement of the switch push arm 49, that is, the push block 44 drives the switch push arm 49 to swing more flexibly, which is beneficial to the flexible switch action. Specifically, the push block 44 can move forward by a small amplitude or swing up and down by a small amplitude, as shown in Figure 1 and Figure 3 Since the middle part of the elastic pressing piece 441 is arranged on the front side of the front end surface 4402 of the push block 44, the push angle portion 4403 abuts against the connecting elastic pressing piece 441. When the push block 44 moves forward, the elastic pressing piece 441 will be elastically deformed and arched forward. When the push block 44 swings, the push angle portion 4403 will lift the corresponding part of the elastic pressing piece 441, so that the corresponding part of the elastic pressing piece 441 is elastically deformed and arched forward. After the switch action is completed, the elastic restoring force of the elastic pressing piece 441 can drive the push block 44 to reset to Figure 1In the shown state, at this time, due to the upper and lower push angle portions 4403 abutting against the rear side of the elastic pressing sheet 441, the wobbling loosening of the push block 44 is avoided, and compared with the two-piece split structure of the prior art, due to the single-piece integral structure of the elastic pressing sheet 441, the structure is relatively simple, and the reset stability is better, and due to the middle part of the elastic pressing sheet 441 contacting the push block 44 (not the end part of the elastic pressing sheet 441), the anti-torsional deformation capacity of the elastic pressing sheet 441 is better, so that the elastic pressing sheet 441 can reset the push block 44 well, and in the next switch operation, the push block 44 can drive the switch push arm 49 more accurately and stably, thereby being beneficial to the stable function of the switch. Figure 2 As shown, due to the single-piece structure of the elastic pressing sheet 441, and the flat sheet of the elastic pressing sheet 441 in the free state, the assembly of the elastic pressing sheet 441 is relatively simple, which is beneficial to the rapid assembly of the elastic pressing sheet 441, and avoids the need for a bending process of the elastic pressing sheet 441, thereby the pressing sheet type switch self-resetting mechanism of the utility model is beneficial to simplify the assembly and reduce the cost.
[0022] Further, as shown in the drawings, Figure 2 The front end surface 4402 of the push block is a plane, which is beneficial to the easy molding of the front end surface 4402 of the push block; in the non-working state, the front end surface 4402 of the push block can be in parallel contact with the rear surface of the elastic pressing sheet 441, in this embodiment, the elastic pressing sheet 441 can be in a flat state, when the push block 44 moves forward, the front end surface 4402 of the push block and the push angle portion 4403 together push the elastic pressing sheet 441 forward and arch, after the elastic deformation and bending of the elastic pressing sheet 441, the front end surface 4402 of the push block is relatively away from the elastic pressing sheet 441, and the push angle portion 4403 maintains contact with the elastic pressing sheet 441; when the push block 44 wobbles, the push angle portion 4403 pushes the corresponding part of the elastic pressing sheet 441 forward. Since the push block 44 wobbles, the push angle portion 4403 actually contacts the elastic pressing sheet 441, and the upper and lower push angle portions 4403 can simultaneously contact and push the elastic pressing sheet 441, so in some embodiments, the front end surface 4402 of the push block can also be an arc-shaped concave surface.
[0023] Further, as shown in the drawings, Figure 1 And Figure 2 The push angle portion 4403 is a round corner, so when the push block 44 wobbles slightly, the push angle portion 4403 and the corresponding part of the elastic pressing sheet 441 relatively slide, the above-mentioned round corner can guide the elastic pressing sheet 441, which is beneficial to the flexible wobble of the push block 44, and when the push block 44 resets, the above-mentioned round corner is relatively easy to slide on the elastic pressing sheet 441, thereby being beneficial to the flexible and stable reset of the push block 44.
[0024] Further, as shown in the drawings, Figure 1As shown, the front end surface 4402 of the dial block is arranged at the front side of the bottom of the groove 434, so that the dial block 44 has already pushed up the middle part of the elastic pressing sheet 441 (forward) in the non-working state, and the middle arc-shaped elastic deformation of the elastic pressing sheet 441 (actually, the two upper and lower push angle parts 4403 contact the elastic pressing sheet 441) at this time, so that the elastic pressing sheet 441 is pre-elastic deformed, so as to enhance the resetting force of the elastic pressing sheet 441 on the dial block 44, and the hinge shaft head 442 can be pressed and attached to the rear inner wall of the hinge limiting hole 432 through the elastic pushing force of the elastic pressing sheet 441, so that the dial block 44 can be accurately reset, further avoiding the loosening phenomenon of the dial block 44, so as to facilitate the effective transmission of the operating force of the user on the switch to the switch dial arm 49, thereby facilitating the stable function of the switch.
[0025] Further, as shown in Figure 2 The rear side of the pressing sheet positioning block 48 is formed with an avoiding groove 482 for avoiding the elastic pressing sheet 441, as shown in Figure 1 When the dial block 44 moves forward or swings up and down in a small amplitude, the dial block 44 pushes up the elastic pressing sheet 441 forward, and the avoiding groove 482 avoids the elastic pressing sheet 441, so as to avoid the interference of the elastic pressing sheet 441 with the elastic deformation of the pressing sheet positioning block 48.
[0026] Further, as shown in Figure 2 The inner wall of the groove 434 is formed with a buckle 4341, and the pressing sheet positioning block 48 is formed with a buckling recess 481, and the buckle 4341 buckles the corresponding buckling recess 481, so that during the assembly of the pressing sheet positioning block 48, the pressing sheet positioning block 48 is slightly squeezed to open the groove 434, and when the buckle 4341 reaches the buckling recess 481, the groove 434 restores the shape, so that the buckle 4341 enters the corresponding buckling recess 481, and the forward movement of the pressing sheet positioning block 48 is blocked by the buckle 4341, thereby avoiding the pressing sheet positioning block 48 from falling out. The above structure can quickly install and position the pressing sheet positioning block 48 in the inner key 43.
[0027] The switch function part 4 of the utility model, as shown in Figure 4As shown, including bottom shell 41, cover shell 42 and switch switching kit 45, cover shell 42 cover is provided on the front side of bottom shell 41, cover shell 42 and the front part of bottom shell 41 buckles, switch switching kit 45 is arranged in bottom shell 41, switch switching kit 45 belongs to the prior art, the switch function piece of the utility model still includes the tablet type switch self-resetting mechanism described above, the front part of switch operating arm 49 is up and down swing articulated in cover shell 42, specifically, the push block 44 is to push the switch operating arm 49 backward to make the switch operating arm 49 swing up and down, the inner key 43 is arranged in the cover shell 42 and slides forward and backward, that is to say, the inner wall of the cover shell 42 plays a guiding role for the forward and backward movement of the inner key 43, the rear end of the reset spring 46 is connected with the cover shell 42. Since the switch function piece 4 of the utility model is provided with the tablet type switch self-resetting mechanism of the utility model, the switch function piece 4 is beneficial to simplify assembly and reduce cost.
[0028] The self-resetting switch of the utility model, such as Figure 4 As shown, including the switch function piece 4 described above; the self-resetting switch of the utility model further includes a face frame 1 and a key assembly 2, the rear part of the face frame 1 is buckled with a support frame 3, the front part of the cover shell 42 is arranged in the support frame 3, and the cover shell 42 is buckled with the support frame 3, the key assembly 2 is provided with a touch end 221 for pushing the inner key 43 backward, since the structure and principle of the touch end 221 pushing the inner key 43 backward to realize switch switching are prior art and not the focus of the utility model, therefore, no detailed description is made here. Since the self-resetting switch of the utility model is provided with the switch function piece 4 of the utility model, the self-resetting switch of the utility model is beneficial to simplify assembly and reduce cost.
