Description

Technical Field

[0001] The utility model relates to the technical field of Hall sensors, and specifically relates to an anti-interference Hall sensor. Background Technique

[0002] A Hall sensor is a sensor based on the Hall effect. A Hall sensor is a sensor that generates an output voltage pulse when an alternating magnetic field passes through. The amplitude of the pulse is determined by the field strength of the excitation magnetic field. Hall sensors are widely used. In the measurement field, they can be used to measure magnetic fields, currents, displacements, pressures, vibrations, rotational speeds, etc. In the communication field, they can be used for amplifiers, oscillators, phase-sensitive detectors, mixers, frequency dividers, and microwave power measurements, etc. In the field of automation technology, they can be used for brushless DC motors, speed sensing, position sensing, automatic counting, proximity switches, servo systems composed of Hall synchros, and automatic electric drive systems, etc. With the continuous development of society and the continuous progress of people's living standards, people often engage in game entertainment in their spare time, and Hall sensors are installed inside the joysticks of the gamepads used by people when playing games;

[0003] However, when people currently use gamepads for entertainment games, since the human body has a certain temperature, when the user's thumb contacts the joystick in the gamepad for a long time, the temperature of the joystick will rise. At the same time, the joystick is powered on, and the temperature of the joystick will further increase after long-term use. High temperature will have a certain impact on the Hall sensor, causing its performance to decline, and thus affecting the sensitivity of the joystick. Therefore, it does not meet the existing requirements, and for this reason, we propose an anti-interference Hall sensor. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti-interference Hall sensor to solve the problem that when people use gamepads for entertainment games, since the human body has a certain temperature, when the user's thumb contacts the joystick in the gamepad for a long time, the temperature of the joystick will rise. At the same time, the joystick is powered on, and the temperature of the joystick will further increase after long-term use. High temperature will have a certain impact on the Hall sensor, causing its performance to decline, and thus affecting the sensitivity of the joystick as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an anti-interference Hall sensor, including a Hall sensor main body:

The lower ends of the flexible hoses are embedded inside the metal shielding cover. Semi-conical soft sheets are installed on both sides of the upper end inside the flexible hoses. Thirty-two air inlet holes are annularly arrayed on the outside of the rubber protective part. Air through holes are arranged at the upper ends of the flexible hoses. Plastic one-way exhaust valves are arranged inside the air inlet holes and the air through holes.

[0008] Preferably, a limiting guide rail is fixedly installed at the upper end of the auxiliary heat conducting plate. An anti-disengagement slider is slidably connected to the outside of the limiting guide rail through a card slot.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model can effectively reduce the interference of external magnetic fields by installing a metal shielding cover, enhancing the anti-interference ability of the Hall sensor main body. A metal heat conducting plate is installed at the rear end of the metal shielding cover to separate the Hall sensor main body from the outside air, preventing external dust from falling on the upper end of the Hall sensor main body and ensuring the cleanliness of the upper end of the Hall sensor main body.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figures 1-4 , an embodiment provided by the present utility model: an anti-interference Hall sensor, including a Hall sensor main body 1:

[0024] A metal shielding cover 2, which is arranged at the upper end of the Hall sensor main body 1. Installing the metal shielding cover 2 can effectively reduce the interference of the external magnetic field and enhance the anti-interference ability of the Hall sensor main body 1. A metal heat conducting plate 7 is installed at the rear end of the metal shielding cover 2 to separate the Hall sensor main body 1 from the external air, prevent external dust from falling on the upper end of the Hall sensor main body 1, and ensure the cleanliness of the upper end of the Hall sensor main body 1. The metal heat conducting plate 7 is fixedly connected to the metal shielding cover 2. An auxiliary heat conducting plate 8 is installed at the rear end of one side of the metal shielding cover 2. Installing the metal heat conducting plate 7 and the auxiliary heat conducting plate 8 can increase the contact area between the metal shielding cover 2 and the air, and further enhance the heat conducting ability of the metal shielding cover 2. The auxiliary heat conducting plate 8 is fixedly connected to the metal shielding cover 2;

[0025] A rubber protection part 4, which is arranged at the upper end of the metal shielding cover 2. A rocker contact part 6 is arranged at the upper end of the Hall sensor main body 1. Sixteen flexible hoses 17 are annularly arranged at the lower end of the rocker contact part 6. The flexible hoses 17 are fixedly connected to the rocker contact part 6. Installing the flexible hoses 17 can make the rocker contact part 6 squeeze the flexible hoses 17 when the user rotates the rocker contact part 6, causing the flexible hoses 17 to deform. Then, the air inside the flexible hoses 17 is pressed into the metal shielding cover 2 through the semi-conical soft pieces 18, and the high-temperature air inside the metal shielding cover 2 is discharged from the device through the air outlet net window 3, thereby reducing the temperature inside the device, preventing the temperature inside the device from being too high, which may cause the performance of the Hall sensor main body 1 to decline, and enhancing the use effect of the device. The lower ends of the flexible hoses 17 are embedded inside the metal shielding cover 2. Semi-conical soft pieces 18 are installed on both sides of the upper end inside the flexible hoses 17. Thirty-two air inlet holes 5 are annularly arranged outside the rubber protection part 4. An air through hole 19 is arranged at the upper end of the flexible hoses 17. Plastic one-way exhaust valves are arranged inside the air inlet holes 5 and the air through hole 19.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, a limiting guide rail 9 is fixedly installed at the upper end of the auxiliary heat conduction plate 8. An anti - detachment slider 10 is slidably connected to the outside of the limiting guide rail 9 through a card slot. Installing the anti - detachment slider 10 can shield the upper end of the first mounting foot 12, prevent the fastener installed inside the first mounting foot 12 from spinning, and ensure the stable installation of the device. A first mounting foot 12 is fixedly installed at the lower end of the rear side of one side of the metal shielding cover 2. A second mounting foot 14 is installed at the lower end of the other side of the front face of the metal shielding cover 2. The second mounting foot 14 is fixedly connected to the metal shielding cover 2. A flipping limiting cover 15 is installed on the side of the second mounting foot 14 close to the auxiliary heat conduction plate 8. Installing the flipping limiting cover 15 can shield the second mounting foot 14 and prevent the fastener installed inside the second mounting foot 14 from shaking. The flipping limiting cover 15 is connected to the second mounting foot 14 through a hinge. Two fixed silicone suction cups 16 are fixedly installed inside the upper end of the flipping limiting cover 15. An electrical connecting member 13 is installed on the front face of the front side of the Hall sensor body 1 away from the auxiliary heat conduction plate 8. The electrical connecting member 13 is electrically connected to the Hall sensor body 1. An air outlet mesh window 3 is installed on the outside of the metal shielding cover 2. The air outlet mesh window 3 is fixedly connected to the metal shielding cover 2. A positioning screw 11 is installed at the upper end of the anti - detachment slider 10. The positioning screw 11 is threadedly connected to the anti - detachment slider 10. The Hall sensor body 1 is fixedly connected to the metal shielding cover 2 through a card slot. The semi - conical soft sheet 18 is fixedly connected to the flexible hose 17.

[0027] Working principle: When in use, the staff installs this device inside the game controller. When the user uses this device, the user's thumb will push the rocker contact 6 to move. At this time, the rocker contact 6 will squeeze the flexible hose 17. Since plastic one-way exhaust valves are provided inside both the flexible hose 17 and the rubber protection part 4, the air inside the flexible hose 17 is directionally discharged into the metal shielding cover 2 through the semi-conical soft piece 18. Then, the cold air from the outside replaces the hot air inside the metal shielding cover 2, and the hot air is discharged from the device through the air outlet net window 3. As the rocker contact 6 is continuously pushed to move during use, the air inside the device also continuously flows, thereby reducing the temperature inside the device, preventing the device from overheating and causing performance degradation, and making the anti-interference ability of the device stronger. Installing the metal shielding cover 2 can effectively reduce the interference of the external magnetic field and enhance the anti-interference ability of the Hall sensor main body 1. A metal heat conduction plate 7 is installed at the rear end of the metal shielding cover 2 to separate the Hall sensor main body 1 from the outside air, preventing external dust from falling on the upper end of the Hall sensor main body 1 and ensuring the cleanliness of the upper end of the Hall sensor main body 1. Installing the metal heat conduction plate 7 and the auxiliary heat conduction plate 8 can increase the contact area between the metal shielding cover 2 and the air, further enhancing the heat conduction ability of the metal shielding cover 2. Installing the flexible hose 17 allows the rocker contact 6 to squeeze the flexible hose 17 when the user rotates the rocker contact 6, causing the flexible hose 17 to deform. Then, the air inside the flexible hose 17 is pressed into the metal shielding cover 2 through the semi-conical soft piece 18, and the high-temperature air inside the metal shielding cover 2 is discharged from the device through the air outlet net window 3, thereby reducing the temperature inside the device, preventing the temperature inside the device from being too high and causing performance degradation of the Hall sensor main body 1, and enhancing the use effect of the device. Installing the anti-slip block 10 can block the upper end of the first mounting foot 12 to prevent the fastener installed inside the first mounting foot 12 from spinning, ensuring the stable installation of the device. Installing the flip limit cover 15 can block the second mounting foot 14 to prevent the fastener installed inside the second mounting foot 14 from shaking.
