DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a vehicle relay detection test bench, comprising a test bench body 1, a relay sample 2 arranged inside the test bench body 1, a power switch 201 connected to the relay sample 2 through a wire, and a counter 202 arranged on the power switch 201;

[0027] A cover plate 4 is clamped on the test bench body 1, and a sand storage chamber 401 is arranged inside the cover plate 4. Two supporting plates 402 are rotatably connected inside the cover plate 4. A driving mechanism for driving the supporting plates 402 to rotate is arranged on the cover plate 4. A flame alarm 5 is arranged inside the cover plate 4. A lifting mechanism for driving the relay sample 2 to rise and fall is arranged inside the test bench body 1. A reciprocating pressing mechanism is arranged on the power switch 201. When the flame alarm 5 detects the flame generated by the spontaneous combustion of the relay sample 2, the relay sample 2 is driven to move upward by the second electric push rod, and the wire is separated from the relay sample 2. The first electric push rod drives the supporting plate 402 to rotate, so that the sand inside the sand storage chamber 401 is leaked to extinguish the flame generated by the relay sample 2, thereby improving the fire extinguishing efficiency when the relay sample 2 spontaneously combusts. At the same time, the sand can be reused to reduce resource waste.

[0028] The driving mechanism includes an electric push rod 1 and a connecting rod 403;

[0029] Two electric push rods are connected to the cover plate 4, and each set of electric push rods is rotatably connected to a connecting rod 403. The other end of each connecting rod 403 is rotatably connected to the bottom end of the supporting plate 402. By providing a driving mechanism, the two supporting plates 402 can be flipped over, and the sand inside the sand storage chamber 401 can be discharged in time for fire extinguishing.

[0030] The lifting mechanism includes an electric push rod 2 and a storage frame 404;

[0031] An electric push rod 2 is connected inside the test bench body 1, and the output end of the electric push rod 2 is connected to a storage frame 404. The inner wall of the storage frame 404 fits the outer wall of the relay sample 2, and the wires on the relay sample 2 are slidably connected to the storage frame 404. By providing a lifting mechanism, the self-igniting relay sample 2 can quickly come into contact with the sand, and the wires connected inside the relay sample 2 can also be separated from the relay sample 2.

[0032] The reciprocating pressing mechanism includes a pressing rod 3, a pressing plate 301, a spring 302, a cam 303 and a motor;

[0033] An inverted U-plate is connected to the test bench body 1, and a pressing rod 3 is slidably connected to the inverted U-plate. A pressing plate 301 is connected to the top of the pressing rod 3, and a spring 302 is connected to the bottom of the pressing plate 301. The other end of the spring 302 is connected to the inverted U-plate. A fixed block is connected to the inverted U-plate, and a motor is connected to the fixed block. A cam 303 is sleeved on the output end of the motor. Through the reciprocating pressing mechanism, under the action of the cam 303 and the spring 302, the pressing rod 3 can move back and forth, so that the power switch 201 can be pressed continuously, and then the relay sample 2 can be powered on and off, thereby testing the relay sample 2. With the action of the counter 202, the number of presses can be recorded.

[0034] A slide groove 405 is provided inside the test bench body 1 , and the inner wall of the slide groove 405 fits with the outer wall of the storage frame 404 . Under the action of the slide groove 405 , the movement of the storage frame 404 can be limited.

[0035] The top opening of the storage frame 404 is arranged in an arc shape, which guides the sand and reduces the sand from overflowing into the interior of the test bench body 1 .

[0036] A transparent acrylic plate is connected to the cover plate 4, so that the amount of sand inside the sand storage chamber 401 can be understood. A plug is connected to the top entrance of the sand storage chamber 401, so that workers can fill the sand into the sand storage chamber 401 easily.

[0037] Working principle: First, a worker opens the cover plate 4 and puts the relay sample 2 into the storage frame 404. Then, after plugging the wire connected to the power switch 201 into the relay sample 2, the cover plate 4 can be inserted into the test bench body 1 to form a closed space between the test bench body 1 and the cover plate 4, thereby simulating the actual use environment of the relay. Then, the motor is started to drive the cam 303 to rotate, so that the cam 303 squeezes the pressing plate 301, and the pressing rod 3 slides inside the inverted U plate, thereby causing the bottom end of the pressing rod 3 to press against the pressing plate 301. When the switch of the power switch 201 is pressed, the pressing plate 301 connected to the pressing rod 3 is quickly restored to its original position under the action of the spring 302, so that the outer wall of the cam 303 is always in contact with the top of the pressing plate 301. Under the action of the cam 303 and the spring 302, the pressing rod 3 can move back and forth, so that the power switch 201 can be pressed continuously, thereby powering on and off the relay sample 2, thereby testing the relay sample 2, and the number of presses can be recorded under the action of the counter 202;

[0038] When relay sample 2 is repeatedly switched on and off, resulting in unstable current, overheating and spontaneous combustion, relay sample 2 will automatically cut off the power, and the flame alarm 5 can detect the flame generated by the spontaneous combustion of relay sample 2, thereby starting electric push rod 2, so that the output end of electric push rod 2 drives the storage frame 404 to move upward, so that the side wall of the storage frame 404 slides on the inner wall of the slide groove 405, and the storage frame 404 moves, so that the wire connected to relay sample 2 is disconnected, and the wire is detached from the inside of relay sample 2, and the output end of electric push rod 1 drives connecting rod 403 to move, so that the supporting plate 402 rotates inside the sand storage chamber 401, so that the sand inside the sand storage chamber 401 enters the storage frame 404, thereby extinguishing the flame.

[0039] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
