The traditional plectrum switch generally comprises components and parts such as plectrum, connecting piece, axis of rotation, fixing base, spring, switch electronic plate, and the plectrum inner is connected with the connecting piece, and a axis of rotation passes fixing base and connecting piece, realizes the rotation installation of plectrum and connecting piece, restricts the range of motion of plectrum through the fixing base simultaneously. Therefore, in the conventional scheme, the problems of reduced structural reliability, high cost and the like exist because of the large number of used parts.

In order to overcome the above technical drawbacks, referring to fig. 1-15, the present embodiment provides a trigger assembly, which is the same as a conventional toggle switch, and specifically is a mechanical control assembly, which can indirectly control the opening and closing of the push type electronic switch 6, and can be applied to various devices requiring to indirectly control and trigger the electronic switch 6. For example, a circuit board in a shell of a steering wheel of an existing vehicle is provided with a plurality of electronic switches 6 capable of controlling certain functions of the vehicle, and for convenience of manual control, the triggering component of the scheme can be installed in the shell of the steering wheel, one end of the triggering component is located outside the shell, the other end of the triggering component extends into the shell and contacts with the electronic switches 6, and a user can manually toggle the triggering component to trigger on-off of the electronic switches 6.

On the basis of the structure, if the rotating shaft and the connecting piece are simply arranged into an integrated structure, the rotating shaft cannot be installed in a mode of axially inserting into a rotating installation hole on the fixed seat; and because the length of the rotating shaft can be larger than the distance between the rotating mounting holes at two sides in the fixed seat, two ends of the rotating shaft integrated with the connecting piece cannot penetrate into the rotating mounting holes at two sides of the fixed seat. Therefore, in the face of this obstacle, it is not reasonable for a person skilled in the art to provide the rotation shaft and the connection member as a unitary structure.

In this embodiment, referring to fig. 13, the rotary shaft 3 and the dial 1 are in an integral structure, which simplifies the structure of the assembly and reduces the number of parts of the assembly.

The rotating shaft 3 and the shifting piece 1 are used as an integral structure, and can be directly and integrally formed, such as manufacturing by injection molding, CNC, die casting and the like; or the two parts can be formed by split combination, for example, after the rotating shaft 3 and the poking sheet 1 are respectively processed and formed in the production stage of the parts, the rotating shaft and the poking sheet are welded, clamped or bonded. Both modes can realize the integrated assembly of the rotating shaft 3 and the poking piece 1 in the assembly stage of the product.

Specifically, the notch of the rotation mounting groove 211 may be located on the inner wall surface of the main body casing 7 or may be located on the outer wall surface of the main body casing 7. When the notch of the rotation mounting groove 211 is located on the inner wall surface of the main housing 7, the opposite first through hole 212 is close to the outer wall surface of the main housing 7, the combined structure of the dial 1 and the rotating shaft 3 needs to be mounted from the inner side of the main housing 7, that is, the control portion 111 needs to extend to the outer side of the main housing 7 through the first through hole 212, and the corresponding gland 22 needs to cover the rotation mounting groove 211 from the inner side of the main housing 7. When the notch of the rotation mounting groove 211 is located on the outer wall surface of the main housing 7, the opposite first through hole 212 is close to the inner wall surface of the main housing 7, the combined structure of the dial 1 and the rotating shaft 3 needs to be mounted from the outer side of the main housing 7, that is, the trigger portion 112 needs to extend into the main housing 7 through the first through hole 212, and correspondingly, the pressing cover 22 needs to cover the rotation mounting groove 211 from the outer side of the main housing 7.

In another embodiment, the rotating shaft 3 is connected to an end of the swing rod 11 away from the handle 12.

Specifically, in this manner, the rotation center of the swing rod 11 is disposed at the end of the rotating shaft 3, so the middle part of the swing rod 11 needs to be able to correspond to the upper part of the electronic switch 6, and when the handle 12 of the swing rod 11 is pressed, the middle part of the swing rod 11 is able to press the electronic switch 6, so as to achieve the purpose of controlling the electronic switch 6 to be closed. Of course, in this embodiment, the rotation support 2 can only be independently disposed inside the main housing 7, and cannot be directly integrally formed on the enclosure of the main housing 7.

In an embodiment, referring to fig. 1-2, the swing rod 11 is sleeved with a sealing sleeve 4, and the sealing sleeve 4 is tightly contacted with the support main body 21 to form a seal.

Specifically, the rotary mounting groove 211 and the first through hole 212 are formed in the support main body 21, which is equivalent to the through hole formed in the enclosure of the host housing 7, so that the sealing sleeve 4 is directly sleeved on the swing rod 11 for protecting an internal circuit board, and the sealing sleeve 4 can be in close contact with the support main body 21, so that the sealing of the through hole is realized, and the problem that dust and water enter the host housing 7 to pollute the circuit board is avoided.

In an embodiment, referring to fig. 12 to 14, the sealing sleeve 4 is provided with a first perforation 41 and a second perforation 42 which are distributed in a cross shape, so that the swing rod 11 can penetrate through the first perforation 41, the rotating shaft 3 can penetrate through the second perforation 42, and the sealing sleeve 4 can be embedded into the rotating mounting groove 211 and closely contacted with the side part of the rotating mounting groove 211.

Specifically, the oscillating bar 11 and the rotating shaft 3 form a cross structure, and the scheme is characterized in that the first perforation 41 and the second perforation 42 which are distributed in a cross shape are correspondingly arranged on the sealing sleeve 4, so that the sealing sleeve 4 can be just sleeved at the joint of the oscillating bar 11 and the rotating shaft 3, and the installation reliability of the sealing sleeve 4 on the shifting plate 1 is ensured. Meanwhile, the sealing sleeve 4 can be embedded into the rotary mounting groove 211, so that the purpose that the sealing sleeve 4 is in close contact with the support main body 21 is achieved, the structure does not need to be sealed by glue between the sealing sleeve 4 and the support main body 21, and the sealing sleeve has the advantages of convenience in assembly while ensuring reliable sealing performance.

Referring to fig. 12 and 13, the diameter of the rotating shaft 3 is larger than the thickness of the swing rod 11, so that the tightness of the inner hole of the sealing sleeve 4 can be ensured as long as the inner wall of the second through hole 42 can be tightly contacted with the outer wall of the rotating shaft 3. In order to avoid that the arrangement of the sealing sleeve 4 hinders the normal swinging of the swinging rod 11, the aperture of the first perforation 41 can be set to be larger than the external dimension of the swinging rod 11, so that the swinging rod 11 can swing at a certain angle relative to the sealing sleeve 4 in the swinging process of the swinging rod 11 around the rotating shaft 3. Therefore, the structure does not affect the normal swing of the plectrum 1 on the basis of realizing reliable sealing performance.

In one embodiment, referring to fig. 14, the sealing sleeve 4 includes a bellows 43 and a first end 44 and a second end 45 connected to two ends of the bellows 43, respectively, the first through hole 41 penetrates the first end 44 and the second end 45 longitudinally, the second through hole 42 penetrates the bellows 43 transversely, and an outer wall of the bellows 43 closely contacts a sidewall of the rotation mounting groove 211.

Specifically, the outer wall of the corrugated portion 43 is provided with a plurality of annular corrugated protrusions, and the external dimension of the corrugated portion 43 can be set to be larger than the internal dimension of the rotary mounting groove 211, so that the corrugated portion 43 can be tightly attached to the side wall of the rotary mounting groove 211 after mounting.

In one embodiment, the gland 22 is formed with a second via 223 allowing the control portion 111 or the trigger portion 112 to pass through, the size of the corrugated portion 43 is larger than the size of the second via 223, the size of the first end portion 44 is smaller than the size of the second via 223, so that the corrugated portion 43 can closely contact the inner side of the gland 22, and the first end portion 44 can be embedded in the second via 223.

Specifically, the second through hole 223 provided on the gland 22 may be penetrated by the control portion 111 or the trigger portion 112, and may also block the rotating shaft 3, so as to limit the rotating shaft 3 in the rotation mounting groove 211. With reference to fig. 9, based on the structure of the gland 22, the first end 44 of the sealing sleeve 4 is embedded into the second via hole 223 in this scheme, so that the second via hole 223 can limit the first end 44, and the stability of installation of the sealing sleeve 4 is improved.

In one embodiment, the corrugated portion 43 extends into the first via 212 and is in close contact with a sidewall of the first via 212.

Specifically, since the side portion of the rotation mounting groove 211 needs to be provided with a rotation groove allowing the rotation shaft 3 to be placed in, the sealing sleeve 4 cannot seal the rotation groove, and the corrugated portion 43 is extended into the first through hole 212 in this scheme, from the structure of the whole through hole formed by the rotation mounting groove 211 and the first through hole 212, a part of the inner wall of the through hole is completely contacted with the outer wall of the sealing sleeve 4, so that the requirement of completely sealing the through hole can be met.

In one embodiment, the notch of the rotation mounting groove 211 is located on the outer wall surface of the main housing 7, and the gland 22 is covered on the support body 21 from the outer side of the main housing 7.

In general, referring to fig. 12, the swing lever 11 of the dial 1 has a long length and is generally in a zigzag structure to adapt to the condition restrictions of the installation environment, and a handle 12 is generally connected to the outer end of the control part 111 for facilitating the manipulation by a human hand. The notch of the rotation mounting groove 211 is provided on the outer wall surface of the main body case 7, and when the trigger portion 112 is mounted, the trigger portion can be inserted into the rotation mounting groove 211 from outside, and the problem that the presence of the handle 12 hinders the mounting of the dial 1 is not considered. Therefore, the handle 12 and the swing rod 11 can be of an integrally formed structure, and in the same way, the structure of the plectrum 1 is simplified, the number of parts is reduced, the reliability of the structure is improved, and the production cost is reduced.

In an embodiment, the gland 22 includes a first gland 221 and a second gland 222 that can be installed independently, a second through hole 223 is formed between the first gland 221 and the second gland 222, and the swing rod 11 penetrates through the second through hole 223, so that the rotating shaft 3 can be placed in the rotating installation groove 211.

As can be seen from the foregoing, in this embodiment, the rotating shaft 3 needs to be installed in the rotation installation groove 211, and then the gland 22 is installed on the support main body 21 to close the rotation installation groove 211, and the gland 22 is difficult to be sleeved outside the swing rod 11 through the second through hole 223 due to the limitation of the structure of the dial 1, so that the gland 22 has a problem of difficult installation. For this reason, referring to fig. 11, the present embodiment provides the gland 22 with a structure in which the first gland 221 and the second gland 222 are combined, and the second via 223 is formed between the first gland 221 and the second gland 222, specifically, C-shaped notches may be provided on at least one of the opposite sides of the first gland 221 and the second gland 222, and when the two are spliced, the second via 223 may be formed in a closed state. In assembly, since the first gland 221 and/or the second gland 222 are provided with the open C-shaped notch, the C-shaped notch can be directly clamped to the side of the swing rod 11 in installation, so that the first gland 221 and the second gland 222 can be attached and fixed to the support body 21. It can be seen that the gland 22 of this embodiment has the advantage of convenient installation.

Optionally, fastening holes are respectively formed on the first gland 221 and the second gland 222, a threaded hole is formed on the support main body 21, and when the support is installed, fastening screws 225 are used to penetrate through the fastening holes and then are locked in the threaded holes, so that the first gland 221 and the second gland 222 can be reliably installed.

In an embodiment, a positioning protrusion 2211 is convexly disposed on a side of the first gland 221, which is close to the second gland 222, and a positioning slot 2221 is correspondingly disposed on the second gland 222, so that positioning is provided for accurate splicing of the first gland 221 and the second gland 222 by matching the positioning protrusion 2211 with the positioning slot 2221.

Specifically, the first gland 221 and the second gland 222 are independently installed, and due to the error of the machining precision of the parts, it is difficult to ensure that the first gland 221 and the second gland 222 can be accurately spliced after installation, and the dislocation of the first gland 221 and the second gland 222 can affect the appearance of the product.
