Description

Technical Field

[0001] The utility model relates to the field of circuit switches, in particular to a driving device for a pure flat reset switch. Background Art

[0002] In modern electronic and electrical equipment, switches play a vital role as key components for controlling the on and off of circuits. With the advancement of technology and the continuous improvement of user needs, the design and function of switches are also constantly evolving and upgrading. Among them, the flat reset switch is highly favored by users due to its unique structure, simple and beautiful appearance design and excellent performance of fast response.

[0003] The existing flat reset switch design adopts a flat pressing plate, which is not only beautiful but also easy to clean, meeting the dual needs of users for appearance and practicality. The driving mechanism usually adopts a vertical rocker arm structure, and the moving contact piece is set at the bottom of the rocker arm. In actual use, when the rocker arm swings, the moving contact piece contacts the static contact pieces on both sides by swinging left and right, thereby closing or disconnecting the circuit. Although this design has achieved the basic function of the switch to a certain extent, some of its structural defects have gradually been exposed.

[0004] First, because the moving contact piece is located at the bottom of the rocker arm, the overall thickness of the switch is large, which increases the size of the device and is not conducive to the miniaturization and lightness of the device. In addition, the stroke required to drive the rocker arm to swing is long, which not only increases the complexity of operation, but also further increases the size of the switch. This design is not satisfactory in terms of compactness and aesthetics, and also limits the application of the switch in electronic devices with limited space.

[0005] Secondly, the existing design may not respond quickly and accurately during operation. Since the swing of the rocker arm requires a certain amount of space and time, the user may feel a lag in operation during use, affecting the user experience.

[0006] Therefore, it is necessary to optimize and improve the existing drive mechanism to solve these problems exposed in actual use and improve its overall performance and user experience. Utility Model Content

[0033] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods: Figures 1 to 11The driving device of a pure flat reset switch shown in the figure comprises an insulating shell 51, wherein the insulating shell 51 has a cavity 3, wherein a laterally extending swinging member 5 is hingedly connected in the cavity 3 along the front-to-back length direction of the cavity 3, and an inlet conductive sheet 2 is provided on the inner wall of the cavity 3 at one end of the swinging member 5, wherein one end of the inlet conductive sheet 2 passes through the outer wall of the insulating shell 51 from the cavity 3 and is connected to the inlet terminal 81 in the switch after being bent for multiple times, and a swinging sheet 54 is movably abutted on the side wall of the inlet conductive sheet 2 facing the rear, and the swinging sheet 54 can be moved in a manner to move in a direction opposite to the inlet conductive sheet 2. One end of the line conductive sheet 2 that is in contact with the line conductive sheet 2 swings up and down about the axis, and a first conductive contact 55 extending toward the rear is provided on the swing sheet 54, a second conductive contact 56 is provided above the first conductive contact 55, and a third conductive contact 57 is provided below the first conductive contact 55, the second conductive contact 56 and the third conductive contact 57 are respectively connected to the line conductive sheet 80, and one end of the two line conductive sheets 80 passes through the outer wall of the insulating shell 51 from the cavity 3 and is respectively connected to the line terminals 82 in the switch after multiple bending. A vertical guide groove 50 which can communicate with the cavity 3 is penetrated on the top wall of the insulating shell 51, and a swing arm driving component 9 which can move up and down along the vertical guide groove 50 and squeeze the front end of the swing member 5 to swing the swing piece 54 up and down is provided in the vertical guide groove 50. When the swing member 5 swings up and down, it can drive the swing piece 54 to swing up and down synchronously, and then make the first conductive contact 55 contact with the second conductive contact 56 and the third conductive contact 57 respectively, so as to realize the closing or opening of the circuit.

[0034] Specifically: Figures 3 to 11 As shown, a movable hole 58 is penetrated downward at the top near the rear end of the swing member 5, and the movable hole 58 is a long strip hole. The swing arm driving assembly 9 includes an extrusion block 91 that can be inserted into the vertical guide groove 50 and can move up and down. The bottom of the extrusion block 91 is concave upward and provided with a moving groove 92. A first spring groove 921 with a width greater than the moving groove 92 is provided in the center of the moving groove 92. A first return spring 94 is embedded in the first spring groove 921. A spring 94 that can move downward is provided at the bottom of the extrusion block 91. The translation block 93 passes through the movable hole 58, and the top of the translation block 93 is provided with stoppers 931 that can extend upward into the movable groove 92. The two stoppers 931 respectively abut against the two ends of the first return spring 94. A second return spring 95 with its lower end abutting against the bottom surface of the cavity 3 is pressed against the bottom of the translation block 93. The front and rear ends of the translation block 93 are respectively provided with first extrusion inclined surfaces 96, and the top surface of the swinging member 5 is respectively provided with second extrusion inclined surfaces 97 that can cooperate with the corresponding first extrusion inclined surfaces 96.

[0035] The swing member 5 includes a swing seat 52 hinged to the left and right side walls of the cavity 3 and a swing arm 53 extending laterally from the front side wall of the swing seat 52. The movable hole 58 runs through the swing seat 52. A notch 531 capable of clamping the swing piece 54 is provided at the front end of the swing arm 53. An embedding groove 532, one end of which can pass through one end of the notch 531, is provided in the swing arm 53. A stabilizing spring 533 is provided in the embedding groove 532. The front end of the stabilizing spring 533 abuts against the edge of the swing piece 54. The stabilizing spring 533 can help the swing arm 53 swing into place faster, reduce the time of swinging, and allow the user to not feel the hysteresis of the operation when using it, thereby improving the user experience. It can also assist the swing piece 54 to maintain the final posture after swinging, and prevent the swing piece 54 from swinging in the opposite direction again. The top of the swing seat 52 located at the front and rear sides of the movable hole 58 is respectively provided with a bottom triangular block 98 protruding upward, and the two second extrusion slopes 97 are respectively provided on the front side and the rear side of the bottom triangular block 98. The translation block 93 includes a moving plate 930 arranged between the bottom of the extrusion block 91 and the swing seat 52. The area of ​​the moving plate 930 is larger than the area of ​​the moving groove 92, so that the bottom of the extrusion block 91 can push against the moving plate 930. The stoppers 931 are respectively arranged at intervals on the top of the moving plate 930, and an extension tube 932 extending downward and extending into the movable hole 58 is provided at the bottom of the moving plate 930. The top end of the second return spring 95 is inserted into the extension tube 932. The bottom surfaces of the front and rear ends of the moving plate 930 are respectively provided with top triangular blocks 99 protruding downward, and the two first extrusion slopes 96 are respectively provided on the inner side walls of the two top triangular blocks 99. The top triangular block 99 and the bottom triangular block 98 are designed correspondingly, so when the corresponding second extrusion slope 97 and the first extrusion slope 96 move up and down and contact, an extrusion dislocation pushing effect can be generated. In addition, the left and right side walls of the extrusion block 91 are respectively penetrated with assembly grooves 911 that can be connected with the moving groove 92, and the assembly groove 911 is in a strip shape from front to back. The left and right sides of the moving plate 930 are respectively provided with hooks 933 that can be inserted into the moving groove 92 and snapped into the corresponding assembly groove 911, and the hooks 933 can slide forward and backward along the assembly groove 911. By snapping the hooks 933 in the assembly groove 911, the extrusion block 91 and the translation block 93 will not be separated at will during the up and down movement, causing the drive device to be stuck or damaged due to excessive extrusion and collision force.

[0036] When the panel housing 7 is pressed at any position, the panel housing 7 and the pressing plate 4 will move downward. During the descent process, the pressing plate 4 will squeeze the squeezing block 91 above the swing seat 52 and move downward along the vertical guide groove 50. At the same time, the squeezing block 91 pushes the translation block 93 to move downward synchronously. After the first squeezing slope 96 at one end of the translation block 93 contacts the second squeezing slope 97 on the top surface of the corresponding swing seat 52, the translation block 93 is squeezed between the slopes, and the translation block 93 moves laterally along the moving groove 92, and the first reset spring 94 is compressed. At the same time, the swing seat 52 squeezed by the translation block 93 begins to flip downward, driving the swing arm 53 to swing up and down, so that the swing piece 54 can be swung synchronously, and then the first conductive contact 55 on the swing piece 54 is in contact with the third conductive contact 57 below to conduct electricity. When the pressure applied to the panel housing 7 disappears, the second reset spring 95 at the bottom of the translation block 93 is deformed and reset, pushing the translation block 93 upward, and the translation block 93 pushes the squeezing block 91 to move upward again. At this time, the first extrusion bevel 96 and the second extrusion bevel 97 separated due to the mutual extrusion. The first return spring 94, which lost the lateral compression force, began to stretch and reset, and pushed the translation block 93 back to its original position again. When the panel housing 7 and the pressing plate 4 are pressed downward again, the other second extrusion bevel 97 on the top surface of the swing seat 52 moves to the bottom of the first extrusion bevel 96 at the other end of the translation block 93 as the swing seat 52 flips. Therefore, when the translation block 93 is pressed down by the pressing plate 4 against the extrusion block 91, the second extrusion bevel 97 of the swing seat 52 that is tilted up for a section will first contact with the first extrusion bevel 96 on the corresponding side of the translation block 93 and produce extrusion. At this time, the translation block 93 will be pushed in the opposite direction of the swing plate 54, and the other end of the first return spring 94 will be squeezed. At the same time, the swing seat 52 is turned upward by the downward pressure, and the swing arm 53 begins to rise, and drives the swing piece 54 to turn upward, so that the first conductive contact 55 leaves the third conductive contact 57 and then contacts and conducts electricity with the second conductive contact 56 above. When the pressure applied to the panel housing 7 disappears again, the second reset spring 95 repeats the action of driving the translation block 93 to push the extrusion block 91 to reset. In order to allow the panel housing 7 and the pressing plate 4 to move up and reset smoothly after being pressed. A spring piece 59 is provided on the top side of the insulating shell 51, which extends obliquely upward and covers the top of the extrusion block 91. The spring piece 59 can help the switch pressing plate 4 to be more easily squeezed to the extrusion block 91 to drive the internal swing piece 5 to swing up and down horizontally, thereby realizing the closing or disconnection of the circuit. It can also lift the switch pressing plate 4 after being pressed down, and help the second reset spring 95 to reset more easily. Through the above-mentioned laterally swinging swinging member 5 structure, in conjunction with the swing arm drive assembly 9, the stroke required for the swing arm to swing can be effectively reduced, the entire flat reset switch can be made thinner, the space occupied can be reduced, and the application of the switch in electronic devices with limited space can be increased.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
