This technical solution is more accurate in detection, not restricted by the site, has better use effect, effectively prevents the device from falling off the vehicle chassis, and is more practical.

[0004] The vehicle braking distance detection device disclosed in the above document has the following defects: The vehicle braking distance detection device is adsorbed on the vehicle chassis through a suction cup. When the detection device needs to be removed from the vehicle chassis, it is necessary to pull the detection device downward forcefully, so that the suction cup cancels the adsorption effect with the vehicle chassis. During the process of pulling the detection device downward, it is easy to cause damage to the connection between the connecting rod and the suction cup. At the same time, the vehicle vibrates during the detection process, and the impact force brought by the vibration may also cause the suction cup to fall off the vehicle chassis, and the use effect is poor.

[0005] It can be seen that the existing vehicle braking distance detection device does not have a good adsorption structure, and it is necessary to improve the existing deficiencies and provide a vehicle braking distance detection device. Content of the Utility Model

[0015] (1) By rotating the knob of the utility model, the one-way screw rod axially moves upward or downward with the threaded hole as the center. When the one-way screw rod moves upward, the one-way screw rod pushes the suction cup to move towards the end close to the vehicle chassis through the connecting piece, so that the suction cup gradually presses the vehicle chassis. At the same time, the negative pressure inside the suction cup is gradually discharged, so that the adsorption effect between the suction cup and the vehicle chassis is cancelled. Furthermore, the damage of the suction cup caused during the process of pulling down the detection device is avoided, and a good practical effect is achieved.

[0016] (2) The utility model filters ferromagnetic impurities in the water source entering the cylinder through the arranged magnetic suction rod, completing the preliminary filtration of the water source.

Specific Embodiments

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figure 1 - Figure 5 As shown in the figure, the present invention is a vehicle braking distance detection device, including a mounting plate 1. A water tank 2 and a sleeve 3 are installed on the lower surface of the mounting plate 1. An air pump 4 is installed at one end of the water tank 2. A trachea 401 is arranged at the air outlet end of the air pump 4. One end of the trachea 401 extends into the interior of the water tank 2. A drain pipe 201 is arranged on the lower surface of the water tank 2. A solenoid valve 5 is installed on the outer surface of the drain pipe 201. A sliding plate 6 is slidably connected inside the sleeve 3. A tape measure 7 is installed on the lower surface of the sliding plate 6. A nut 8 is threadedly connected to the outer surface of the sleeve 3. A connecting plate 9 is arranged at the upper end of the mounting plate 1. A damper 10 is installed between the connecting plate 9 and the mounting plate 1. A spring 11 is sleeved on the outer surface of the damper 10. One end of the spring 11 is installed on the upper surface of the mounting plate 1, and the other end of the spring 11 is installed on the lower surface of the connecting plate 9. An installation opening is formed on the upper surface of the mounting plate 1, and an adsorption assembly 12 is arranged inside the installation opening. A filtering assembly 13 is arranged at one end of the water tank 2 away from the air pump 4.

[0028] The adsorption assembly 12 includes a housing 1201. The housing 1201 is installed inside the installation opening. A suction cup 1202 is arranged on the upper surface of the housing 1201. A through hole is formed on the lower surface of the housing 1201, and a one-way screw 1203 is arranged inside the through hole. A connecting member is arranged on the upper surface of the one-way screw 1203, and the suction cup 1202 is installed on the upper surface of the connecting member;

[0029] A knob 1204 is arranged at the lower end of the housing 1201. A threaded hole is formed on the upper surface of the knob 1204, and the one-way screw 1203 is threadedly connected inside the threaded hole. A sealing groove is formed on the upper surface of the housing 1201, and a sealing ring 1205 is fitted and installed inside the sealing groove.

[0030] During use, first place the mounting plate 1 on the upper surface of the vehicle chassis. By rotating the knob 1204, the one-way screw rod 1203 axially moves upward or downward around the threaded hole. When the one-way screw rod 1203 moves downward, the one-way screw rod 1203 pulls the suction cup 1202 downward through the connecting member, causing a negative pressure to be generated inside the suction cup 1202, and thus enabling the suction cup 1202 to adsorb on the outer surface of the vehicle chassis; when it is necessary to remove the detection device from the vehicle chassis, by rotating the knob 1204 in the reverse direction, the one-way screw rod 1203 moves upward, causing the one-way screw rod 1203 to push the suction cup 1202 toward the end close to the vehicle chassis through the connecting member, causing the suction cup 1202 to gradually squeeze the vehicle chassis, and the negative pressure inside the suction cup 1202 is gradually discharged, causing the suction cup 1202 to cancel the adsorption effect with the vehicle chassis, thereby avoiding damage to the suction cup 1202 during the process of pulling down the detection device.

[0031] When vibrations occur during vehicle detection, the vibrations of the vehicle chassis are transmitted to the mounting plate 1. At the same time, the vibrations cause the spring 11 to be gradually stretched and push the connecting plate 9 to slide downward. When the spring 11 is stretched, it absorbs the impact force. When the spring 11 resets, it causes the connecting plate 9 to slide upward and push the damper 10, causing the output end of the damper 10 to gradually contract. By providing the damper 10, the vibration amplitude and impact can be effectively reduced, thereby improving the stability of the detection device.

[0032] The filtering component 13 includes a housing 1301. A drain pipe 1302 is provided on the upper surface of the housing 1301. A cover body 1303 is threadedly connected to the lower surface of the housing 1301. A water inlet pipe 1304 is provided on the lower surface of the cover body 1303. One end of the drain pipe 1302 extends into the interior of the water tank 2. A connecting rod 1305 is provided inside the housing 1301, and a cylinder body 1306 is provided at the other end of the connecting rod 1305.

[0033] Before use, connect an external water outlet device to the water inlet pipe 1304, and then start the external water outlet device, so that the water source enters the interior of the cylinder body 1306 through the water inlet pipe 1304.

[0034] A filter element 1307 is provided inside the cylinder body 1306, and a magnetic suction rod 1308 is installed at the inner top of the cylinder body 1306.

[0035] After the water source enters the cylinder body 1306, the magnetic absorption rod 1308 arranged in the cylinder body 1306 can filter the ferromagnetic impurities in the water source entering the cylinder body 1306 to complete the preliminary filtration of the water source. At the same time, through the arranged filter element 1307, the solid impurities in the water source can be filtered. The filtered water source enters the interior of the water tank 2 through the drain pipe 1302, preventing the ferromagnetic impurities and solid impurities in the water source from entering the interior of the water tank 2, thereby avoiding the blockage problem of the drain pipe 201 and achieving a good filtering effect.
