[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0023] The present embodiment provides a button module without screw locking, which can perform modular installation of the button module to avoid the integrated installation of the button module and the display module. When the button module fails, the button module can be quickly removed, thereby making the use of the button module more flexible and greatly reducing the use of screws on the button module, thereby achieving high simplicity and greater practicality.

[0024] like Figure 1 As shown, the key module includes a housing 10 and a cover plate 20 , and a plurality of operation buttons 12 are disposed on the housing 10 .

[0025] Combination Figures 2 to 4 As shown, at least two locking holes 11 are provided on the housing 10, and the locking holes 11 are spaced apart along the length direction of the housing 10; a locking member 21 is provided on the cover plate 20, and the number of the locking members 21 and the locking holes 11 are the same and one-to-one corresponding, and a locking hole 211 is provided on the locking member 21, and the locking hole 211 and the locking hole 11 are locked by a threaded pin 30, and a locking inclined surface 2111 is provided in the locking hole 211, and when the threaded pin 30 enters the locking hole 211, the locking member 21 is pressed down to make the cover plate 20 close to the housing 10, and when the housing 10 and the cover plate are locked, the locking member 21 is locked. During the locking process of 20, the locking hole 211 on the locking member 21 is aligned with the locking hole position 11, the threaded pin 30 is placed in the locking hole 211, and the threaded pin 30 is continuously rotated. During the inward movement of the threaded pin 30, since a locking inclined surface 2111 is provided in the locking hole 211, the locking member 21 is pressed downward during the continuous inward movement of the threaded pin 30. During the downward pressing process of the locking member 21, the cover plate 20 is driven to move downward, so that the gap between the cover plate 20 and the shell body 10 is smaller, the locking is tighter, and the locking effect is further improved.

[0026] In this embodiment, a locking limit piece 40 is provided at the locking hole 11 , and the locking limit piece 40 is coaxially arranged with the locking hole 11 , forming a further limit structure during the locking process of the threaded pin 30 , thereby improving the locking effect.

[0027] like Figure 3 As shown, a groove 22 is provided on the cover plate 20, and a waterproof rubber ring 221 is provided in the groove 22. The waterproof rubber ring 221 is arranged along the circumference of the cover plate 20. During the locking process of the shell 10 and the cover plate 20, the locking effect between the shell 10 and the cover plate 20 is better, and a certain waterproof effect can be achieved.

[0028] In this embodiment, the locking member 21 is a T-shaped seat, and is fixedly mounted on the cover plate 20. The use of the T-shaped seat as the locking member 21 is convenient for installation and is conducive to the smooth performance of the locking operation.

[0029] Combination Figure 2 and Figure 3As shown, a top protrusion 13 is provided on the shell 10, and a fastening limit plate 23 is provided on the cover plate 20. The fastening limit plate 23 cooperates with the top protrusion 13 to reinforce and lock the cover plate 20 and the shell 10. During the locking process of the shell 10 and the cover plate 20, the top protrusion 13 will cooperate with the fastening limit plate 23 to make the locking between the shell 10 and the cover plate 20 tighter, thereby further improving the locking effect between the shell 10 and the cover plate 20.

[0030] Specifically, in this embodiment, the fastening and limiting piece 23 is an L-shaped structure, which can better cooperate with the top protrusion 13 on the shell 10.

[0031] During the actual installation of the key module of this embodiment, the cover plate 20 is first covered on the shell 10 to fit the cover plate 20 with the shell 10, and then the threaded pin 30 is inserted into the locking hole 211, and the threaded pin 30 is manually driven to rotate. The threaded pin 30 will lock the shell 10 and the cover plate 20 during the inward movement. The presence of the locking inclined surface 2111 in the locking hole 211 allows the threaded pin 30 to squeeze the locking member 21 during the continuous movement, thereby reducing the gap between the cover plate 20 and the shell 10, making the two more tightly locked, and further improving the locking effect of the shell 10 and the cover plate 20.

[0032] In summary, this embodiment can install the button module in a modular manner, avoiding the integrated installation of the button module and the display module. When the button module fails, the button module can be quickly removed, thereby making the use of the button module more flexible and greatly reducing the use of screws on the button module, thereby achieving high simplicity and greater practicality.

[0033] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
