[0006] Preferably, one end of the flexible pressing member away from the opening and closing device is defined as the pressing end, and the output end is arranged on one side close to the pressing end.

[0007] Preferably, when the flexible pressing member moves in a direction close to the opening and closing device, the light guide column abuts against the opening and closing device; when the flexible pressing member moves away from the opening and closing device, the light guide column still abuts against the opening and closing device.

[0008] Preferably, the ratio of the depth of the cavity to the height of the flexible pressing member is between 1:2 and 1:1.

[0009] Preferably, an annular groove is formed on the outer side surface of one end of the flexible pressing member close to the opening and closing device.

[0010] Preferably, the opening and closing device is a micro switch.

[0011] Preferably, the light-emitting device is an LED lamp.

[0012] To solve the above technical problems, in another embodiment of the present invention, a flashlight is provided. The flashlight includes a barrel and the above-mentioned button device, and the button device is arranged on the barrel.

[0013] Preferably, the flashlight further includes a display screen and a control circuit board. The display screen is arranged on the barrel, the control circuit board is arranged inside the barrel, and the opening and closing device, the control circuit board, and the display screen are electrically connected in sequence.

[0014] Compared with the prior art, the button device and the flashlight of the present invention have the following advantages:

[0015] 1. The button device in an embodiment of the present invention includes a flexible pressing member, an opening and closing device, and a light-emitting device. The flexible pressing member can move in a direction close to or away from the opening and closing device. The flexible pressing member abuts against the opening and closing device. A cavity is formed at one end of the flexible pressing member close to the opening and closing device. The light-emitting device is arranged on one side of the opening of the cavity. The opening and closing device is electrically connected to the light-emitting device. The flexible pressing member is easily deformed under external force. Through the above arrangement, when the user presses the flexible pressing member, the flexible pressing member moves towards the opening and closing device and presses the opening and closing device, so that the opening and closing device sends a signal, and then the electrically connected light-emitting device can be controlled to generate light, so as to emit a light prompt message, realizing the convenient transmission and real-time feedback response of the user operation instruction. A cavity is formed at one end of the flexible pressing member close to the opening and closing device, and the light-emitting device is arranged on one side of the opening of the cavity, which is convenient for the light emitted by the light-emitting device to be conducted through the cavity, making the display effect of the light more transparent.

[0016] 2. The button device in an embodiment of the present utility model further includes a light guide column, which includes an input end and an output end. The input end is arranged on the side close to the light-emitting device, and the output end is arranged in the cavity. The input end abuts against the opening and closing device, and the output end abuts against the flexible pressing member. The light guide column can effectively focus and guide the light emitted by the light-emitting device, making it more concentrated and improving the conduction efficiency. The light guide column effectively improves the distribution of the light beam emitted by the light-emitting device and provides more uniform lighting. The input end being arranged on the side close to the light-emitting device greatly reduces the light loss from the light-emitting device to the light guide column, while the output end being arranged in the cavity provides additional physical protection for the light guide column, making it not easily affected by external impacts or damages. The cavity can also cooperate with the light guide column to optimize the light propagation path through reflection and refraction, improving the uniformity and efficiency of lighting. Since the input end of the light guide column abuts against the opening and closing device and the output end abuts against the flexible pressing member, the light guide column also serves as a force transmission member and plays an important role in force transmission. Existing buttons do not use a light guide column with both ends abutting as a force transmission member, but only rely on elastic members such as rubber with a certain compression amount to provide an upward elastic force. It is the upward elastic force provided by the elastic member with a certain compression amount that enables the user to press down. However, this also causes the elastic member to lift the operation panel where the button is located, affecting the aesthetic flatness. By setting the input end of the light guide column to abut against the opening and closing device and the output end to abut against the flexible pressing member, the light guide column can transmit force, effectively improving the pressing feel and enabling the user to obtain a better pressing feedback experience.

[0017] 3. In an embodiment of the present utility model, one end of the flexible pressing member away from the opening and closing device is defined as the pressing end, and the output end is arranged on the side close to the pressing end. By arranging the output end on the side close to the pressing end, the light guide column can conduct the light emitted by the light-emitting device to the side close to the pressing end, so that it is easy to penetrate the pressing end and be recognized by the user, providing clear and obvious light prompt information for the user.

[0018] 4. When the flexible pressing member moves towards the direction close to the opening and closing device in an embodiment of the present utility model, the light guide column abuts against the opening and closing device; when the flexible pressing member moves away from the opening and closing device, the light guide column still abuts against the opening and closing device. Through the above arrangement, no matter which direction the flexible pressing member moves, the light guide column abuts against the opening and closing device, and the light guide column, as a force transmission member, can continuously and stably transmit the force.

[0019] 5. In an embodiment of the present utility model, the ratio of the depth of the cavity to the height of the flexible pressing member is between 1:2 and 1:1. By setting the ratio of the depth of the cavity to the height of the flexible pressing member between 1:2 and 1:1, it is ensured that the cavity has sufficient depth and space to accommodate the light guide column, and there is a relatively thin distance between the bottom of the cavity and the end of the flexible pressing member away from the opening and closing device, so as to facilitate the light conducted by the light guide column to penetrate the flexible pressing member.

[0020] 6. In one embodiment of the present utility model, an annular groove is provided on the outer side surface of one end of the flexible pressing member close to the opening and closing device. By providing the annular groove on the outer side surface of one end of the flexible pressing member close to the opening and closing device, the flexible pressing member is made easier to press.

[0021] 7. The opening and closing device in one embodiment of the present utility model is a micro switch. The micro switch is small in size, facilitating installation and use within the limited space of the button device. Due to its simple structure, the micro switch can quickly respond to user operations, realizing instant switching of the working state of the flashlight. In addition, the micro switch can withstand a large number of switch operations without damage, being suitable for the high-frequency switch operations of the flashlight.

[0022] 8. The light-emitting device in one embodiment of the present utility model is an LED lamp. The light-emitting device using an LED lamp has the advantage of fast response speed, can be instantaneously started based on the electrical signal of the micro switch without waiting, providing timely and reliable light prompt information for the user. Moreover, the LED light source is small in size, facilitating the structural design of the button device, and enabling the button device to be more compact and lightweight.

[0023] 9. The flashlight in one embodiment of the present utility model includes a barrel and the above-mentioned button device, and the button device is arranged on the barrel. The flashlight has the same effective effects as the above-mentioned button device, which will not be elaborated herein.

[0024] 10. The flashlight in one embodiment of the present utility model further includes a display screen and a control circuit board. The display screen is arranged on the barrel, and the control circuit board is arranged inside the barrel. The opening and closing device, the control circuit board, and the display screen are electrically connected in sequence. By providing the display screen and the control circuit board, and electrically connecting the opening and closing device, the control circuit board, and the display screen in sequence, the user operation can control the switch of the opening and closing device by pressing the flexible pressing member, and then the control circuit board can control the working state of the flashlight and the display state of the display screen according to the on-off of the circuit of the opening and closing device, realizing an efficient and convenient control path and a clear display effect.

For those of ordinary skill in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0040] Please refer to Figures 1 to 3 , a first embodiment of the present utility model provides a button device 60, the button device 60 includes a flexible pressing member 61, an opening and closing device 62, and a lighting device 63. The flexible pressing member 61 can move in a direction close to or away from the opening and closing device 62. The flexible pressing member 61 abuts against the opening and closing device 62. A cavity 611 is formed at one end of the flexible pressing member 61 close to the opening and closing device 62. The lighting device 63 is arranged on one side of the opening of the cavity 611. The opening and closing device 62 is electrically connected to the lighting device 63.

[0041] It can be understood that the flexible pressing member 61 has the characteristic of being easily deformed under external force. Through the above arrangement, when a user presses the flexible pressing member 61, the flexible pressing member 61 moves towards the opening and closing device 62 and presses the opening and closing device 62, causing the opening and closing device 62 to send a signal. Furthermore, it can control the lighting device 63 that is electrically connected to generate light, thereby emitting a light prompt message, realizing the convenient transmission and real-time feedback response of the user operation instruction. A cavity 611 is formed at one end of the flexible pressing member 61 close to the opening and closing device 62. The lighting device 63 is arranged on one side of the opening of the cavity 611, facilitating the light emitted by the lighting device 63 to be conducted through the cavity 611, making the display effect of the light more transparent.

[0042] Optionally, the flexible pressing member 61 can be made of a material that is easily deformed under external force, such as silicone, plastic, or polymer.

[0043] Please refer to Figure 2 and Figure 3 , further, the button device 60 further includes a light guide column 64. The light guide column 64 includes an input end 641 and an output end 642.

The output end 642 abuts against the flexible pressing member 61.

[0044] Understandably, the light guide column 64 can effectively focus and guide the light emitted by the light-emitting device 63, making it more concentrated, improving the conduction efficiency. The light guide column 64 effectively improves the distribution of the light beam emitted by the light-emitting device 63, providing more uniform lighting. The input end 641 is arranged on the side close to the light-emitting device 63, greatly reducing the light loss when the light-emitting device 63 shoots towards the light guide column 64. The output end 642 is arranged in the cavity 611, so that the cavity 611 provides additional physical protection for the light guide column 64, making it not easily affected by external impacts or damages. The cavity 611 can also cooperate with the light guide column 64 to optimize the light propagation path through reflection and refraction, improving the uniformity and efficiency of lighting. Since the input end 641 of the light guide column 64 abuts against the opening and closing device 62, and the output end 642 abuts against the flexible pressing member 61, the light guide column 64 also serves as a force transmission member, playing an important role in force transmission. The existing buttons do not use the light guide column 64 with both ends abutting as a force transmission member, but only rely on elastic members such as rubber with a certain compression amount to provide an upward elastic force. It is the upward elastic force provided by the elastic members such as rubber with a certain compression amount that enables the user to press down. However, this also causes the elastic member to lift the operation panel where the button is located, affecting the aesthetic flatness. By arranging the input end 641 of the light guide column 64 to abut against the opening and closing device 62 and the output end 642 to abut against the flexible pressing member 61, the light guide column 64 can transmit force, improving the pressing feel and enabling the user to obtain a better pressing feedback experience.

[0046] Understandably, by arranging the output end 642 on the side close to the pressing end 612, the light guide column 64 can conduct the light emitted by the light-emitting device 63 to the side close to the pressing end 612, so that it is easy to penetrate the pressing end 612 and be recognized by the user, providing the user with clear and transparent light prompt information.

[0047] Please continue to combine Figure 2 and Figure 3 to further state that when the flexible pressing member 61 moves towards the direction close to the opening and closing device 62, the light guide column 64 abuts against the opening and closing device 62; when the flexible pressing member 61 moves away from the opening and closing device 62, the light guide column 64 still abuts against the opening and closing device 62.

[0048] Understandably, through the above arrangement, no matter which direction the flexible pressing member 61 moves, the light guide column 64 abuts against the opening and closing device 62, and the light guide column 64, as a force transmission member, can continuously and stably transmit the force.

[0049] Please refer to Figure 4 , further, the ratio of the depth of the cavity 611 to the height of the flexible pressing member 61 is between 1:2 and 1:1.

[0050] It should be noted that the depth of the defined cavity 611 is D, and the height of the flexible pressing member 61 is L, where 0.5 ≤ D / L < 1.

[0051] It can be understood that by setting the ratio of the depth of the cavity 611 to the height of the flexible pressing member 61 between 1:2 and 1:1, it is ensured that the cavity 611 has sufficient depth and space to accommodate the light guide column 64, and there is a relatively thin spacing between the bottom of the cavity 611 and the end of the flexible pressing member 61 away from the opening and closing device 62, so as to facilitate the light transmitted by the light guide column 64 to penetrate the flexible pressing member 61.
