[0032] The utility model provides a kind of button switch remote control device, referring to Figure 1 And Figure 2The button switch remote control device comprises a shell 1, a motor 2, a main control board 3 and a pressing assembly 4. The shell 1 is provided with a mounting port 111, and the button switch 8 can be mounted into the shell 1 through the mounting port 111. The motor 2 and the main control board 3 are electrically connected and arranged in the shell 1. The main control board 3 is used for receiving a pressing instruction sent by an external management system and controlling the motor 2 to work based on the pressing instruction. The pressing assembly 4 is rotatably arranged in the shell 1 and provided with a pressing part 413 and a force transmission part 414. The motor 2 is in transmission cooperation with the force transmission part 414 through a transmission member 5, so that the force transmission part 414 drives the pressing part 413 to press or release the button switch 8.

[0033] Based on the above scheme, the button switch 8 can be directly installed above the button switch 8. The circuit at the back of the button switch 8 does not need to be disassembled and replaced, and does not need to be reconnected to the power grid circuit for modification. The installation is relatively simple and the use cost is low. The main control board 3 can remotely receive an operation instruction. The main control board 3 controls the motor 2 to start. The motor 2 drives the pressing assembly 4 to rotate through the transmission member 5. The pressing part 413 remotely controls the button switch 8 to press the button switch 8. Remote control of the button switch 8 is realized. This way, manual on-site operation at the substation is not required, solving the problem of time-consuming and labor-intensive on-site manual operation. The efficiency and reliability of operating the button switch 8 are effectively improved. Moreover, the modification of the existing mechanical button switch 8 does not need to disassemble the circuit, which can avoid power outage and other safety accidents, and improve the safety of use.

[0034] Referring to Figures 1 to 8 The transmission member 5 is a transmission cam connected with the output shaft of the motor 2. The transmission cam has a driving protrusion 51 in sliding contact with the force transmission part 414. The driving protrusion 51 is used to drive the force transmission part 414 to rotate, so that the pressing part 413 is in a pressing state or a non-pressing state.

[0035] The transmission cam has a small end and a large end in the shape of a water droplet. The large end is regularly circular. The large end is fixedly connected with the output shaft of the motor 2. Specifically, the large end is provided with a mounting hole. Part of the hole wall of the mounting hole is arranged as a plane. The output shaft of the motor 2 can be in surface contact with the hole wall of the mounting hole. In this way, the transmission cam can be driven. The small end is protruding to form the driving protrusion 51. When the motor 2 drives the transmission cam to rotate, the driving protrusion 51 rotates to contact the force transmission part 414. The driving protrusion 51 pushes the force transmission part 414 to rotate to drive the pressing part 413 to rotate, so that the pressing part 413 presses the button switch 8, and remote control of the button switch 8 is realized.

[0036] When the driving protrusion 51 is switched to the large end and the force transmission part 414, the transmission member 5 no longer exerts power on the force transmission part 414, that is, the pressing part 413 is in a released state, the pressing on the button switch 8 is released, and the operation of pressing and releasing the button switch 8 is realized. The transmission cam and the force transmission part 414 are in sliding contact in a curved surface contact manner, which facilitates the power transmission between the transmission cam and the force transmission part 414. In order to better contact and transmit power between the transmission cam and the force transmission part 414, the cross section of the force transmission part 414 can be circular or arc-shaped.

[0037] The transmission member 5 can also be other structural members capable of resisting and pushing the pressing part 413 to rotate, such as a cam gear. The cam gear is in meshing connection with the pressing part 413, that is, the force transmission part 414 is driven to rotate in a gear transmission manner to realize the rotation of the pressing part 413 to press the button switch 8.

[0038] Referring to Figures 1 to 8 The pressing assembly 4 includes a pressing member 41 and a reset member 42.

The reset member 42 is used to provide a reset restoring force for the pressing member 41.

[0039] The pressing member 41 is bent. On the one hand, it is designed to adapt to the internal space structure of the housing 1. On the other hand, it enables the pressing member 41 to press the button switch 8 in a smaller rotation range, has the effect of reducing the rotation space, and realizes remote control of the button switch 8 with a simple structure. After the pressing member 41 presses the button switch 8, the reset member 42 can provide a reset restoring force for the pressing member 41. The pressing member 41 returns to the initial position under the action of the reset member 42 to realize reset. The reset member 42 can be a torsion spring. The torsion spring is sleeved on the connecting body 412 of the pressing member 41. One end of the torsion spring abuts against the housing 1 or an internal mounting member, and the other end abuts against the pressing member 41. The torsion spring provides a reset force for the pressing member 41 to realize automatic reset.

[0040] The pressing member 41 includes a pressing body 411 and a connecting body 412. The pressing body 411 is rotationally connected to the housing 1 through the connecting body 412. The pressing part 413 and the force transmission part 414 are formed at two ends of the pressing body 411. The connecting body 412 is an axle body arranged on both sides of the pressing body 411 to facilitate rotationally connecting with the housing 1 or a mounting bracket 13 of the housing 1. The part between the pressing part 413 and the force transmission part 414 of the pressing body 411 is arched. The connecting body 412 is arranged on the arched part. The connecting body 412 enables the pressing body 411 to rotate to realize the rotation of the force transmission part 414 to drive the pressing part 413 to press the button switch 8.

[0041] The moment of force between the force transmission part 414 and the connecting body 412 is smaller than the moment of force formed between the pressing part 413 and the connecting body 412. In this way, a force lever is formed, so that the force transmission part 414 cannot be easily rotated when the motor 2 malfunctions and is mistakenly operated, and the occurrence of mistaken operation can be avoided to a certain extent, thereby reducing the risk of power safety accidents.

[0042] With reference to Figures 1 to 8 The shell 1 is provided with an operation opening 121, and the button switch remote control device further comprises a mechanical key 7 arranged at the operation opening 121, which is used to provide a manual pressing mode for the button switch 8.

The number of limiting grooves 122 can be two, and the two limiting grooves 122 are arranged on both sides of the operation opening 121. Correspondingly, the number of limiting protrusions 71 is two, and the two limiting protrusions 71 are matched one by one with the two limiting grooves 122, so that the limitation of the mechanical key 7 is increased, and the mechanical key 7 can be stably assembled on the shell 1.

[0044] The mechanical key 7 is provided with a containing groove 72 and a avoiding gap 73 communicating with the containing groove 72, and the pressing part 413 is arranged in the containing groove 72 through the avoiding gap 73. The containing groove 72 can provide a rotating space for the pressing part 413 to avoid affecting the rotation of the pressing part 413. Through the containing groove 72 and the avoiding gap 73 of the mechanical key 7, the pressing part 41 can be conveniently installed, and the structure space can be saved and the structure compactness can be improved.
