[0027] like Figures 1 to 6 As shown, an embodiment of the present invention provides a non-locking light-touch key switch, including a base 100, a sealing block 101, a pressure claw, a static piece 105 and a positioning mechanism. A first groove is opened on the base 100, and the extension direction of the depth of the first groove is assumed to be the first direction. The sealing block 101 is slidably arranged in the first groove along the first direction. The sealing block 101 is slidably connected to the side of the first groove. A sealed first cavity 106 is formed between the sealing block 101 and the bottom surface of the first groove. One side of the pressure claw is connected to the sealing block 101, and the other side of the pressure claw is slidably connected to the side of the first groove. The static piece 105 is provided with a plurality of, and a plurality of The static piece 105 is fixedly installed on the base 100, and one end of each static piece 105 is arranged on the side of the first groove and is located in the first cavity 106. The pressure claw can be slidably connected with multiple static pieces 105 at the same time and make the multiple static pieces 105 connected with the pressure claw electrically connected; the pressure claw can adjust the contact pressure between the side of the first groove according to the change of the pressure in the first cavity 106, and the pressure between the pressure claw and the side of the first groove is positively correlated with the pressure in the first cavity 106; the positioning mechanism is used to make the pressure claw and the static piece 105 connected multiple times during the process of pressure recovery in the first cavity 106.

[0028] A first cavity 106 is set, and when the pressure claw is close to the static plate 105, the volume of the first cavity 106 decreases and the pressure increases. By coordinating the pressure between the pressure claw and the side of the first groove and the pressure in the first cavity 106, the contact pressure between the pressure claw and the side of the first groove will increase. When the pressure claw contacts the static plate 105, the contact pressure between the pressure claw and the static plate 105 is also increased, thereby improving the connection stability between the pressure claw and the static plate 105; a positioning mechanism is set, and after the pressure claw and the static plate 105 are separated for the first time, the pressure in the first cavity 106 can still be greater than the pressure outside it, and external impurities will not easily enter the first cavity 106, thereby reducing the content of impurities in the first cavity 106 and extending the service life of the pressure claw and the static plate 105.

[0029] In the present embodiment, the projection of the first groove in the first direction is a polygon, the shape of the sealing block 101 is adapted to the first groove, a second groove 107 is provided on the peripheral surface of the sealing block 101, the second groove 107 is communicated with the first cavity 106, the pressing claw comprises a fixing plate 102 and a first elastic plate 103, the first elastic plate 103 is an elastic plate, and the first elastic plate 103 is in a flat state in a natural state; the fixing plate 102 is fixedly mounted on a side of the second groove 107 away from the base 100, a side surface of the first elastic plate 103 is connected to the fixing plate 102, the first elastic plate 103 is curved, a side surface of the first elastic plate 103 away from the fixing plate 102 is located between the bottom surface of the first groove and a side surface of the first elastic plate 103 connected to the fixing plate 102, and the first elastic plate 103 is located in the first cavity 10 6, the first spring piece 103 is slidably connected to the side of the first groove, and the two side surfaces of the first spring piece 103 adjacent to the fixing plate 102 and parallel to the first direction are slidably connected to the two side surfaces of the second groove 107 respectively. When the sealing block 101 is set in the first groove, the first spring piece 103 is deformed by abutting against the side of the first groove, generating abutting pressure. The first spring piece 103 separates part of the second groove 107 from the first cavity 106. When the pressure inside the first cavity 106 increases, the gas pressure inside the first cavity 106 will act on the first spring piece 103, so that the abutting force between the first spring piece 103 and the side of the first groove increases. When the first spring piece 103 contacts the corresponding static piece 105, the contact pressure between the two will also increase, thereby improving the connection stability.

[0030] In this embodiment, the pressure claw also includes a second spring piece 104, which is made of the same material as the first spring piece 103, and is located on a side of the first spring piece 103 away from the first cavity 106. One side of the second spring piece 104 is connected to the fixing plate 102, and the second spring piece 104 is symmetrically arranged on the fixing plate 102 with the first spring piece 103. The second spring piece 104 is slidably connected to the side of the first groove. When the sealing block 101 is reset under the action of the positive pressure in the first cavity 106, the pressure in the first cavity 106 decreases. If the pressure in the first cavity 106 is consistent with the external pressure when the sealing block 101 is not completely reset, the sealing block 101 will still reset. At this time, under the action of atmospheric pressure, the pressure between the second spring piece 104 and the side of the first groove will increase, reducing the probability of external impurities entering the first cavity 106.

[0031] In this embodiment, a plurality of pressure claws are provided, and the number of second grooves 107 is consistent with the number of pressure claws, and each pressure claw corresponds to a second groove 107; a plurality of static plates 105 connected to the same pressure claw are a group, and a plurality of groups of static plates 105 are provided, each group of static plates 105 corresponds to a pressure claw, and each group of static plates 105 is arranged on the same side of the first groove; when the sealing block 101 compresses the first cavity 106 to drive the first spring plate 103 in the pressure claw to approach the corresponding static plate 105, each first spring plate 103 can make a plurality of static plates 105 that need to be electrically connected in the same group be in an electrically connected state.

The sealing strip is slidably connected to the first groove. The sealing strip can increase the sealing effect between the sealing block 101 and the first groove, thereby improving the sealing of the first cavity 106 .

The mounting groove 108 is located between two adjacent second grooves 107, and the mounting groove 108 is respectively connected to the two adjacent second grooves 107. The position that the first spring sheet 103 and the second spring sheet 104 cannot seal is sealed by a sealing strip, which can enhance the sealing effect of the first cavity 106 and also enhance the pressure difference between the two surfaces of the first spring sheet 103, thereby increasing the contact pressure between the pressure claw and the first groove.

[0034] In this embodiment, the lock-free touch button switch also includes an upper cover 109 and a button 110. The upper cover 109 is buckled on the base 100 and covers the first groove. One end of the button 110 passes through the upper cover 109 and the sealing block 101 and extends into the first cavity 106. The button 110 is slidably connected to the upper cover 109 and fixedly connected to the sealing block 101. Pushing the button 110 along the first direction can compress the first cavity 106 and make the pressure claw approach the static plate 105. The pressure in the first cavity 106 increases, and the pressure between the pressure claw and the base 100 increases. The contact pressure of the pressure claw after contacting the static plate 105 increases, and the two are more tightly connected.

[0035] In this embodiment, the positioning mechanism includes a fixed cylinder and a rotating shaft 111. The fixed cylinder is fixedly mounted on a button 110. The axis of the fixed cylinder extends along a first direction. The button 110 is coaxial with the fixed cylinder. A guide groove is provided on the fixed cylinder. The guide groove is arranged around the circumferential direction of the fixed cylinder and connected end to end. The guide groove is provided with a plurality of first poles 116 and a plurality of second poles 117 in the first direction. The first poles 116 and the second poles 117 are arranged alternately, and the plurality of first poles 116 are located on the same plane perpendicular to the axis of the fixed cylinder. The second pole 117 is located between the first pole 116 and the bottom surface of the first groove, and the distance between the multiple second poles 117 and the bottom surface of the first groove gradually decreases from the head end to the tail end of the guide groove. The rotating shaft 111 is rotatably set on the bottom surface of the first groove, and the rotating shaft 111 is sleeved in the fixed cylinder. The rotating shaft 111 is slidably connected with the fixed cylinder. A guide block 112 is provided on the rotating shaft 111, and the guide block 112 is slidably set in the guide groove, and the guide block 112 is alternately connected with the multiple first poles 116 and the multiple second poles 117.

[0036] Specifically, the fixed tube includes a first tube 113 and a second tube 114. The first tube 113 is fixedly mounted on the button 110, and the second tube 114 is located at the end of the first tube 113 away from the button 110. The second tube 114 and the first tube 113 are coaxial and connected by a connecting rod 118. A spacing is provided between the first tube 113 and the second tube 114. The end of the first tube 113 close to the second tube 114 is provided with a plurality of first protrusions, and the end of the second tube 114 close to the first tube 113 is provided with a plurality of second protrusions. The plurality of first protrusions and the plurality of second protrusions are evenly distributed around the axis of the first tube 113; a first pole 116 is provided between two adjacent first protrusions, and the sides of the two adjacent first protrusions close to each other are away from each other from the corresponding first pole 116 position; a second pole 117 is provided between two adjacent second protrusions, and the sides of the two adjacent second protrusions close to each other are away from each other from the corresponding first pole 116 position. The two poles 117 are located away from each other, each first protrusion corresponds to a second pole 117, each second protrusion corresponds to a first pole 116, and each first pole 116 corresponds to an inclined surface of a second protrusion along the first direction, and each second pole 117 corresponds to an inclined surface of a first protrusion along the first direction; when the sealing block 101 compresses the first cavity 106, the guide block 112 slides in the guide groove along the inclined surface of one of the first protrusions to the corresponding first pole 116, and when the sealing block 101 moves in the reverse direction to increase the volume of the first cavity 106, the guide block 112 disengages from the first pole 116 and slides into contact with the inclined surface of the corresponding second protrusion, and under the guidance of the inclined surface of the second protrusion, the guide block 112 slides to the position of the second pole 117; during the process, the guide block 112 drives the rotating shaft 111 to rotate in one direction until it rotates to the starting position to complete a cycle.

[0037] In this embodiment, the lock-free touch key switch also includes a spring 115, which is arranged in the first cavity 106, and the two ends of the spring 115 are respectively connected to the button 110 and the base 100, the spring 115 is sleeved on the fixed cylinder and the rotating shaft 111, and the spring 115 is retracted along the first direction; after the pressure claw contacts the static piece 105, the spring 115 is in a compressed state, providing sufficient power for the sealing block 101 to be completely reset, so that the lock-free touch key switch can be used repeatedly.

[0038] In this embodiment, the base 100 and the static sheet 105 are integrally injection molded to improve the sealing of the first cavity 106 and prevent the gas in the first cavity 106 from being discharged from between the static sheet 105 and the base 100 .

[0039] The working principle of a non-locking light touch key switch provided in the above embodiment is:

[0040] First, install the sealing block 101 into the first groove, and bend the first spring sheet 103 so that the end in contact with the first groove is bent in the direction away from the second spring sheet 104. After the sealing block 101 is installed, buckle the upper cover 109 onto the base 100. At this time, the pressure in the first cavity 106 is slightly greater than the external pressure, and the first cavity 106 is in a positive pressure state.

[0041] Install the lock-free touch button switch to a suitable place and connect the static piece 105 in place; then press the button 110, the button 110 drives the sealing block 101 to slide along the first direction to compress the first cavity 106, and at the same time the sealing block 101 drives the first elastic piece 103 to slide on the side of the first groove through the fixing piece 102, when the first elastic piece 103 contacts the static piece 105, multiple static pieces 105 in the same group are electrically connected.

[0042] When the sealing block 101 compresses the first cavity 106, the spring 115 is compressed, the first tube 113 and the second tube 114 approach the rotating shaft 111, and the guide block 112 drives the rotating shaft 111 to rotate under the action of the first protrusion, and when the guide block 112 moves to the first pole 116, the sealing block 101 can no longer compress the first cavity 106, and the button 110 is released. The sealing block 101 moves in the opposite direction under the action of the spring 115 and the pressure in the first cavity 106, and then the guide block 112 is separated from the first pole 116, and the guide block 112 approaches the second pole 117 under the guidance of the inclined surface of the second protrusion, and the rotating shaft 111 also rotates; when the guide block 112 contacts the second pole 117, the sealing block 101 no longer moves, and the sealing block 101 has not returned to the initial position at this time, the spring 115 is still in a compressed state, and the pressure in the first cavity 106 is still positive; the button 110 is pressed again. , the button 110 drives the first spring piece 103 to approach the static piece 105 through the sealing block 101, the spring 115 is further compressed, and the pressure in the first cavity 106 increases again. The button 110 is released, and the sealing block 101 moves in the opposite direction under the action of the spring 115 and the first cavity 106. During this process, the rotating shaft 111 continues to rotate under the action of the guide block 112, and the guide block 112 moves from the position of the second pole 117 to the first pole 116 and then moves again to the position of the next second pole 117. Relative to the position of the previous second pole 117, the volume of the first cavity 106 is further reduced; when the guide block 112 returns to the initial position after passing through multiple second poles 117 in sequence, the sealing block 101 is completely reset under the action of the spring 115 and the pressure in the first cavity 106; the direction of reverse movement is assumed to be the direction in which the first spring piece 103 moves away from the static piece 105 along the first direction.

[0043] After each pressing of the button 110, the first cavity 106 is under positive pressure, which effectively reduces the probability of impurities outside the first cavity 106 entering the first cavity 106. If the first cavity 106 is under negative pressure after the sealing block 101 is completely reset during use, it means that there is gas leakage in the first cavity 106. At this time, the air pressure outside the first cavity 106 will push the second spring sheet 104 closer to the first spring sheet 103, and the contact pressure between the first spring sheet 103 and the side of the first groove will increase, which can effectively reduce the probability of gas and impurities entering the first cavity 106. If impurities enter the first cavity 106, when the button 110 is pressed, the pressure in the first cavity 106 will also make the first spring sheet 103 and the static sheet 105 contact more closely, thereby improving the connection stability between the first spring sheet 103 and the static sheet 105.

[0044] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
