The locking portion 532 is provided on the end of the connecting rod 531 away from the positioning portion 533. The locking portion 532 is a protrusion provided on the outer periphery of the connecting rod 531. The protrusion surrounds the connecting rod 531. In this embodiment, the protrusion surrounds the connecting rod 531 once, and the axis of the protrusion is collinear with the axis of the connecting rod 531. Specifically, the outer peripheral surface of the locking portion 532 is a convexly curved surface. Further, the outer peripheral surface of the protrusion and the outer peripheral surface of the connecting rod 531 are smoothly connected. Figure 6 Figure 7 As shown in FIGS. 5 and 6, the locking member 53 further includes a locking portion 532. The locking portion 532 is provided on the end of the connecting rod 531 away from the positioning portion 533.

In this embodiment, the protrusion surrounds the connecting rod 531 once, and the axis of the protrusion is collinear with the axis of the connecting rod 531. Specifically, the outer peripheral surface of the locking portion 532 is a convexly curved surface. Further, the outer peripheral surface of the protrusion and the outer peripheral surface of the connecting rod 531 are smoothly connected.

[0040] Preferably, the outer periphery of the key column 54 is provided with a sealing ring 55. The sealing ring 55 is used to prevent external liquid, dust or sundries from entering the receiving space 205 of the housing 20 through the through hole 222 of the housing 20, so as to avoid the pollution or damage of the electronic devices and power supply on the main board 40 in the housing 20. In this embodiment, the sealing ring 55 is made of a waterproof material with elasticity, which can be but is not limited to rubber, plastic or silica gel, etc. The sealing ring 55 is sleeved in the positioning groove 545 of the column body 541.

[0041] ​​Preferably, the key post 54 is connected with the key body 51 through a connecting pad 56. Specifically, the connecting pad 56 is elastic, which includes a pad 561 for abutting against the abutting piece 543 of the key post 54, and a clamping block 563 protruding from the pad 561 for clamping in the positioning hole 5105 of the key body 51. In the embodiment, the connecting pad 56 is made of rubber with elasticity; that is, the connecting pad 56 has elastic deformation performance, and the key body 51 can move relative to the key post 54, so as to avoid the key body 51 from being warped to cause the key post 54 to be tilted and stuck, prevent the key 50 from being inactivated, ensure the effective pressing performance of the key 50, and increase the service life of the key 50. In other embodiments, the connecting pad 56 can be made of plastic, silica gel or other materials with elasticity.

[0042] Preferably, the key 50 further includes at least one elastic member 57, and the at least one elastic member 57 is arranged between the key body 51 and the shell 20, and is used for elastically pushing the key body 51 to move away from the accommodation space 205 of the shell 20. In the embodiment, the key 50 includes two elastic members 57, and each elastic member 57 is a spring for providing elastic restoring force of the key body 51 away from the shell 20. When the key body 51 is pressed, the elastic member 57 is compressed, the key body 51 is close to the shell 20, and the key post 54 can trigger the signal triggering device. When the pressing force of the key body 51 is removed, the elastic force of the elastic member 57 acts on the key body 51, so that the key body 51 slides away from the shell 20. When the connecting foot 511 and the hook 512 respectively abut against the inner side of the guide groove 23 and the locking member 53, the elastic member 57 is in a pre-compressed state, so that the key 50 remains in a pressable state.

[0043] Optionally, the elastic member 57 is a rectangular spring.

[0044] Optionally, the elastic member 57 is a torsion spring.

[0045] In other embodiments, the elastic member 57 can be an elastic rubber block or an elastic plastic block.

[0046] Please refer to Figure 2 - Figure 3 and Figure 9 - Figure 13 , Figure 9 is Figure 1 the assembly state diagram of the shell 20 and the key 50 in Figure 10 is Figure 9 the perspective sectional view of the shell 20 and the key 50 inFigure 11 is an enlarged view of XI part in Figure 10 Figure 12 is a sectional view along XII-XII line in Figure 1 Figure 13 is an enlarged view of XIII part in Figure 12 When the key 50 is assembled to the shell 20, the sealing ring 55 is sleeved on the positioning groove 545 of the key post 54, the end of the key post 54 away from the abutting piece 543 is inserted into the through hole 222 of the shell 20 through the key groove 22, the sealing ring 55 is clamped between the inner peripheral surface of the through hole 222 and the key post 54, so that the sealing ring 55 seals the through hole 222; the clamping block 563 of the connecting pad 56 is clamped in the positioning hole 5105 of the key main body 51; one end of each of the two elastic members 57 is clamped in the connecting hole 5107 of the two connecting barrels 5106; the connecting leg 511 of the key main body 51 is inserted into the guide groove 23 through the key groove 22, the hook 512 is inserted into the containing groove 25 through the key groove 22, and the connecting rod 531 of the locking member 53 is inserted into the positioning hole 252 of the shell 20 from the front surface and passes through the limiting groove 5125 of the hook 512. The guide sliding surface 5331 has a guiding effect, so that the positioning part 533 is more easily inserted into the positioning hole 252, until the positioning part 533 is positioned in the positioning hole 252 after passing through the positioning hole 252 of the front surface of the shell 20, at this time, the locking member 53 passes through the limiting groove 5125 of the hook 512.

[0047] At this time, the key main body 51 is slidably installed in the key groove 22, the connecting leg 511 can slide along the guide groove 23, the hook 512 can slide along the containing groove 25, and the elastic member 57 elastically pushes the key main body 51, so that the connecting leg 511 and the hook 512 abut against the stop table 232 and the locking member 53 respectively, and the connecting leg 511 and the hook 512 are limited in the guide groove 23 and the containing groove 25 respectively. When the locking member 53 is positioned in the positioning hole 252, one end of the positioning part 533 is in interference fit with the positioning hole 252 to play a limiting role, so that the key main body 51 is prevented from being separated from the shell 20 due to the loosening of the locking member 23 in the subsequent use or falling process, the connection reliability of the key 50 is improved, that is, the connection of the key 50 is more firm. In addition, since the positioning part 533 is a protrusion protruding from the outer periphery of the connecting rod 531, when the locking member 53 is assembled in place, there is a clear jerk feeling, and the installation personnel can more easily determine whether the locking member 53 is assembled in place; and the locking member 53 has high repairability and has no influence on after-sales maintenance.

[0048] ​​Since the key 50 only needs to be stably installed in the shell 20 through one locking piece 53, compared with the key structure in the prior art which needs to be installed in the shell through multiple pins, the assembly operation of the key 50 of the present application is simple, the working hours are short, and the assembly efficiency is improved. In addition, compared with the blind assembly of the pin and the pin hole in the prior art, the pin cannot be quickly and accurately inserted into the pin hole, and the pin may not be assembled in place, which affects the key feeling and use; the locking piece 53 cooperates with the limiting groove 5125 of the key body 51 to position the key body 51 to the shell 20, and the width of the limiting groove 5125 is much larger than the outer diameter of the locking piece 53, so the locking piece 53 can be quickly and accurately inserted into the limiting groove, reducing the operation difficulty and operation time of the installer, improving the assembly efficiency, and avoiding the phenomenon that the key cannot be assembled in place, improving the key feeling and use quality.

[0049] Please refer to Figure 14 and Figure 15 , Figure 14 is Figure 12 is a schematic view of the key structure in the prior art in a pressed state; Figure 15 is an enlarged view of the XV part in Figure 14 . When the key structure is used, the outer surface 5102 of the key body 51 is pressed to drive the key body 51 to slide in the key slot 22 relative to the shell 20 to the storage space 205, the connecting foot 511 and the hook 512 are synchronously driven to slide along the guide groove 23 and the accommodating groove 25 respectively, at the same time, the key body 51 pushes the connecting pad 56 to drive the key column 54 to slide along the through hole 222 to the storage space 205, until the key column 54 abuts against the corresponding switch, so that the switch is turned on or off; the two elastic members 57 are pressed to elastically deform, and the sealing ring 55 elastically deforms. When the pressing on the key body 51 is released, the two elastic members 57 elastically reset to push the key body 51 to slide away from the storage space 205 and reset, until the connecting foot 511 is stopped at the stop table 232 and the hook 512 is stopped at the locking piece 53, so as to prevent the key body 51 from being separated from the shell 20; the connecting pad 56 is away from the key column 54, the sealing ring 55 elastically resets to drive the key column 54 to reset, that is, the key column 54 releases the abutment against the switch.

[0050] In other embodiments, the connecting pad 56 can be omitted, and the key column 54 and the key body 51 are an integral structure. Specifically, the key column 54 and the key body 51 can be fixedly connected through clamping, gluing or screwing, etc.; or the key column 54 and the key body 51 can also be integrally formed.

[0051] As Figure 16 shown, Figure 16 is a perspective sectional view of another embodiment of the locking member of the present application. The structure of the locking member 53a is similar to that of the locking member 53 described above, except that the positioning portion 533a of the locking member 53a is provided with inclined guide surfaces 5331 on opposite sides of the axis of the connecting rod 531, which facilitate the positioning portion 533a to be inserted into the positioning hole 252 of the housing 20. Specifically, the positioning portion 533a is a protrusion around one end of the outer periphery of the connecting rod 531, the axis of the protrusion is coaxial with the axis of the connecting rod 531, and the protrusion is provided with the guide surfaces 5331 on opposite sides of the axis of the protrusion. The positioning portion 533a further includes a connecting surface 5332 connected between the two guide surfaces 5331, and the connecting surface 5332 is coaxial with the outer peripheral surface of the connecting rod 531. Each guide surface 5331 is smoothly connected with the outer peripheral surface of the connecting rod 531.

[0052] The above is the embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles of the present application, can make several improvements and refinements, these improvements and refinements are also considered to be within the scope of the present application.
