However, most of the existing intelligent AGV carts need to manually press the elevator button to open the elevator door for the AGV cart when they need to move to other floors. In order to solve the above problems, some people have proposed a technical solution of automatically pressing mechanical buttons, such as the wireless simulation manual triggering external device for the IoT smartphone to call the elevator disclosed in patent publication number CN204958028U, the button controller includes a button control box, one side of the button control box covers the elevator button, and a button touch mechanism is provided in the box covering the elevator button, and the button touch mechanism includes an inner touch key, and the inner touch key is used to touch the elevator button.

[0004] Although the above scheme can realize automatic pressing of elevator buttons, the box body on one side of the control box covers the mechanical buttons of the elevator, and the elevator buttons are completely blocked regardless of whether the elevator buttons need to be pressed. In addition, the touch keys of the device are always exposed outside the box and are easily damaged.

[0046] Embodiment 1

[0047] like Figure 1As shown, a control device for automatically clicking a mechanical key comprises a device housing 1, a working mainboard and a driving motor 3 are arranged in the device housing 1, and a signal receiver is arranged on the working mainboard for receiving external commands. The device housing 1 comprises a receiving chamber 11 and a rod receiving chamber 12, the driving motor 3 is installed in the receiving chamber 11, and its output shaft 31 extends to the rod receiving chamber 12 and is connected to a rotatable button arm 2, and an elastic head is arranged at the front end of the button arm. The operation of the driving motor 3 enables the rotatable button arm 2 to switch between a first state (hidden state) and a second state (working state). When the button arm is in the first state, it is received in the rod receiving chamber 12; while in the second state, the elastic head presses the mechanical key 4.

[0048] When the signal receiver receives the pressing command, the driving motor 3 starts and rotates, driving the rotatable button arm 2 to extend from the rod body storage chamber 12. When the rotatable button arm 2 rotates to the second state, the elastic head is used to press the mechanical key 4. Subsequently, the driving motor 3 rotates in the opposite direction, driving the rotatable button arm 2 to rotate to the first state, and the rotatable button arm 2 is re-stored in the rod body storage chamber 11. When pressing the mechanical key 4, the elastic head of the rotatable button arm 2 has a certain elasticity, providing a buffering effect between the rotatable button arm 2 and the mechanical key 4, effectively preventing damage to the mechanical key 4 or damage to the device itself. In this way, the driving motor 3 can be designed to rotate to a sufficient angle without worrying about crushing the mechanical key 4, thereby ensuring that the rotatable button arm 2 effectively presses the mechanical key 4. Among them, the signal receiver is a Bluetooth signal receiver or an infrared signal receiver or a wifi signal receiver to meet different communication needs.

[0049] In this embodiment, the working main board is located on the left side of the accommodating cavity 11, while the driving motor 3 is located on the right side, and a power socket 14 is provided on the upper side wall of the accommodating cavity 11 corresponding to the working main board. The layout of the electronic components in the accommodating cavity 11 is reasonable and neat, which is convenient for management and maintenance, and at the same time ensures that the device housing 1 has a square shape, a simple structure and is beautiful.

[0050] In an optional implementation, the accommodating cavity 11 is further provided with a battery, which is electrically connected to the working mainboard and the drive motor 3, and is located between the working mainboard and the drive motor 3. The battery can realize the independent use of the control device, and there is no need to set a special drive power supply next to the key panel 41, so that the key panel 41 only has the control device, the key panel 41 is more concise, and the internal clutter of the device is avoided.

[0051] In this embodiment, the elastic head of the rotatable button arm 2 includes an assembly column 21, a touch key block 22 and a spring 23. The bottom of the assembly column 21 is provided with an assembly cavity, the spring 23 is arranged in the assembly cavity, and the touch key block 22 is inserted into the assembly cavity and abuts against the spring 23. The top of the assembly column 21 is provided with a bolt hole connected to the assembly cavity, and the first bolt 24 passes through the bolt hole from top to bottom and is connected to the touch key block 22. When the rotatable button arm 2 presses the motor button, the touch key block 22 presses the mechanical button 4. Under the reaction force, the touch key block 22 retracts into the assembly cavity, squeezes the spring 23 inside, and forms a buffer force; in the process of the touch key block 22 retracting into the assembly cavity, the first bolt 24 extends out of the bolt hole. This design ensures that the touch key block 22 effectively presses the mechanical button 4, and also ensures that the mechanical button 4 is not crushed or the rotatable button arm 2 is not damaged. The touch key block 22 is designed to be detachable and installed by the first bolt 24, which is convenient for maintenance personnel to regularly replace the touch key block 22 and maintain the pressing effect of the rotatable button arm 2.

[0052] In this embodiment, the output shaft 31 is provided with an internal threaded hole, and the rotatable button arm 2 is detachably connected to the output shaft 31 through the second bolt 25. Specifically, the outer wall of the rod body receiving chamber 12 is provided with an assembly hole 121, and the assembly hole 121 is directly opposite to the second bolt 25. The maintenance personnel can use a screwdriver to screw the second bolt 25 from the assembly hole 121 of the rod body receiving chamber 12 to achieve rapid installation or removal of the rotatable button arm 2, which is convenient for the maintenance personnel to regularly check whether the rotatable button arm 2 is loose, and also convenient for the maintenance personnel to replace the rotatable button arm 2.

[0053] In this embodiment, a flat surface is provided at the bottom of the accommodating cavity 11 , a film is placed on the flat surface, and then adhered to the key panel 41 . The flat surface is connected to the key panel 41 through adhesive, and the device housing 1 is placed close to the corresponding mechanical key 4 .

[0054] Embodiment 2

[0055] A control device for automatically clicking mechanical buttons, the rest of the structure is the same as the first embodiment, the difference is that: the shaft of the rotatable button arm 2 includes a first rod 26 and a second rod 27, the first rod 26 and the second rod 27 are detachably connected and the relative distance between the two is adjustable, one end of the first rod 26 is connected to the driving motor 3, and one end of the second rod 27 is provided with an elastic head. When adjusting the relative distance between the first rod 26 and the second rod 27, the second adjustment hole is aligned with part of the first adjustment hole, and then the aligned first adjustment hole and the second adjustment hole are fixedly connected by a fixing pin, so as to fix the first rod 26 and the second rod 27; the adjustment structure is simple and easy to operate, and at the initial stage of the device installation, the length of the rotatable button arm 2 is adjusted, and there is no need to change the length; only when the device is disassembled and installed on other key panels, the relative distance between the first rod 26 and the second rod 27 needs to be readjusted.

[0056] In this embodiment, the first rod body is provided with four first adjustment holes, and the second rod body is provided with two second adjustment holes. The second adjustment holes have the same diameter as the first adjustment holes, ensuring that the fixing pin can be smoothly inserted and fixed. In actual use, the user can select different combinations of adjustment holes to adjust the length of the button arm according to needs. For example, align the two second adjustment holes of the second rod body with the two first adjustment holes at the front end of the first rod body, insert the fixing pin to complete the fixation, and the length of the rotatable button arm 2 is longer; align the two second adjustment holes of the second rod body with the two first adjustment holes at the rear end of the first rod body, insert the fixing pin to complete the fixation, and the length of the rotatable button arm 2 is shorter.

[0057] The adjustment structure of the rotatable button arm 2 provides great flexibility and convenience for the user, so that the same device can adapt to the size requirements of different key panels without the need to design and manufacture different button arms for each size.

[0058] In other embodiments, the first rod body and the second rod body are threadedly connected, and the relative distance between the second rod body and the first rod body is adjusted by twisting the second rod body, thereby changing the length of the rotatable button arm 2 .

[0061] First, the structure of the wave grid 13 not only provides a visually beautiful and modern feel, but also allows the portion of the rod storage cavity 12 that is higher than the accommodating cavity 11 to have a curved arc surface with the top of the accommodating cavity 11, thereby reducing the sharp corners on the outside of the shell and improving the safety of the product. Secondly, the wave grid 13 structure increases the heat dissipation area through its unique shape, which helps to improve the heat dissipation efficiency of the electronic components inside the device, thereby extending the service life of the device and ensuring its stable operation. Finally, the wave grid 13 can also increase the structural strength of the device shell 1.

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.

[0063] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
