Description

Technical Field

[0001] This utility model relates to the field of pressure sensors, specifically a button pressure sensor assembly. Background Technology

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable electrical output signals according to certain rules. A pressure sensor typically consists of a pressure-sensitive element, a device that converts the force or motion generated by the pressure-sensitive element into electrical parameters, and a device that displays or records the electrical parameters.

[0003] Pressure sensors come in a wide variety of types, including button pressure sensors. However, current button pressure sensors are difficult to protect against touch during use. When a button pressure sensor is accidentally touched, it will sense a pressure signal, which will affect the pressure sensing function of the sensor. Therefore, those skilled in the art have provided a button pressure sensor assembly to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a button pressure sensor assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A button pressure sensor assembly includes a mounting base plate. A threaded retaining ring is fixedly connected to the upper surface of the mounting base plate. A protective cover is provided above the mounting base plate. An upper annular plate is fixedly connected to the inner ring of the protective cover. A ring of springs is fixedly connected to the bottom surface of the upper annular plate. An external threaded support cover is threadedly connected to the inner ring of the threaded retaining ring. A lower annular plate is fixedly connected to the inner ring of the external threaded support cover. The bottom end of each spring is fixedly connected to the upper surface of the lower annular plate. A button-type pressure sensor is fixedly mounted on the upper surface of the mounting base plate, and the button-type pressure sensor is located inside the protective cover.

[0007] As a further embodiment of this utility model: two sets of dampers are fixedly connected to the upper surface of the lower annular plate, and the top ends of the two sets of dampers are fixedly connected to the bottom surface of the upper annular plate.

[0008] As a further embodiment of this utility model: the upper surface of the upper annular plate has two sliding holes, and the upper surface of the lower annular plate is fixedly connected to two sliding plates, the top ends of the two sliding plates passing through the sliding holes and extending above the sliding holes.

[0009] As a further embodiment of this utility model: the top ends of both sliding plates are fixedly connected to limiting plates, the bottom surfaces of both limiting plates are fixedly connected to limiting pads, and the bottom surfaces of both limiting pads are in contact with the upper surface of the upper annular plate.

[0010] As a further improvement of this utility model: an annular pad is fixedly connected to the inner top wall of the protective cover, and a through hole is opened on the upper surface of the protective cover.

[0011] As a further improvement of this utility model: a rotating plate is fixedly connected to the outer surface of the external thread support cover, and a groove is provided on the bottom surface of the mounting base plate.

[0012] As a further improvement of this utility model: two mounting components are fixedly connected to the outer surface of the mounting base plate, and the bottom surface of both mounting components is provided with mounting holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This button pressure sensor assembly, through the threaded fixing ring on the mounting base plate, allows the threaded connecting cover to be installed on top of it. At the same time, by utilizing the lower annular plate and spring inside the threaded connecting cover, and in cooperation with the upper annular plate and damper, it can block unintentional external contact, thereby achieving a buffering and protective effect when unintentionally touched.

[0022] Please see Figures 1-4 In this embodiment of the present invention, a button pressure sensor assembly includes a mounting base plate 1. A threaded retaining ring 2 is fixedly connected to the upper surface of the mounting base plate 1. A protective cover 3 is provided above the mounting base plate 1. An upper annular plate 4 is fixedly connected to the inner ring of the protective cover 3. A ring-shaped arrangement of springs 5 ​​is fixedly connected to the bottom surface of the upper annular plate 4. An external threaded support cover 8 is threadedly connected to the inner ring of the threaded retaining ring 2. A lower annular plate 6 is fixedly connected to the inner ring of the external threaded support cover 8. The bottom end of each spring 5 is fixedly connected to the upper surface of the lower annular plate 6. A button-type pressure sensor 7 is fixedly mounted on the upper surface of the mounting base plate 1. The button-type pressure sensor 7 is located inside the protective cover 3. Through the cooperation of the lower annular plate 6 and springs 5 ​​inside the external threaded support cover 8, and the upper annular plate 4 and damper 14, it can block unintentional external contact and provide buffer protection against unintentional external contact.

[0023] As a further improvement of this utility model: two sets of dampers 14 are fixedly connected to the upper surface of the lower annular plate 6. The top ends of the two sets of dampers 14 are fixedly connected to the bottom surface of the upper annular plate 4. Two sliding holes 10 are opened on the upper surface of the upper annular plate 4. Two sliding plates 13 are fixedly connected to the upper surface of the lower annular plate 6. The top ends of the two sliding plates 13 pass through the sliding holes 10 and extend above the sliding holes 10. Limiting plates 11 are fixedly connected to the top ends of the two sliding plates 13. Limiting pads 9 are fixedly connected to the bottom surfaces of the two limiting plates 11. The bottom surfaces of the two limiting pads 9 are in contact with the upper surface of the upper annular plate 4. By setting the dampers 14, the upper annular plate 4 and the protective cover 3 are prevented from vibrating up and down. By using the cooperation of the sliding holes 10, the sliding plates 13 and the limiting plates 11, the protective cover 3 will be limited when it moves upward, ensuring the stability of the protective cover 3 when it is buffered.

[0024] As a further improvement of this utility model: an annular pad 15 is fixedly connected to the inner top wall of the protective cover 3, a through hole 16 is opened on the upper surface of the protective cover 3, a rotating plate 12 is fixedly connected to the outer surface of the external threaded support cover 8, a groove 17 is opened on the bottom surface of the mounting base plate 1, and two mounting parts 18 are fixedly connected to the outer surface of the mounting base plate 1. The bottom surface of the two mounting parts 18 is opened with mounting holes 19. The annular pad 15 can buffer the button-type pressure sensor 7 when it is pressed, which can reduce the collision when it is pressed. The rotating plate 12 can facilitate the rotation of the external threaded support cover 8, which will allow the protective cover 3 to be quickly installed and fixed above the button-type pressure sensor 7. The mounting parts 18 and the mounting holes 19 can facilitate the installation and fixing of the mounting base plate 1.

[0025] The working principle of this utility model is as follows: First, the mounting base plate 1 is installed and fixed through the mounting part 18 and the mounting hole 19. Then, the button-type pressure sensor 7 is connected to the electrical equipment. When the button-type pressure sensor 7 is touched, the protective cover 3 can block the external touch and slide inside the external thread support cover 8. At the same time, it will also drive the extended spring 5 to retract, thus buffering the unintentional pressing of the button-type pressure sensor 7. When the button-type pressure sensor 7 is pressed, the protective cover 3 needs to be pressed down, which can drive the annular pad 15 to squeeze and touch the top of the button-type pressure sensor 7, thereby enabling pressure sensing.
