Description

Technical Field

[0001] The present invention relates to the technical field of automobile testing, and in particular to a waterproof testing device for a new energy automobile. Background Art

[0002] Waterproof test is a type of automobile inspection, which is used to verify the sealing of automobile parts and other products, and provide a basis for product reliability. As a vehicle type that is mainly driven by electricity, the sealing of new energy vehicles is higher than that of conventional fuel vehicles. On this basis, every electric vehicle needs to undergo strict waterproof tests before leaving the factory. The existing waterproof test generally drives the vehicle into a shed-type spraying device, which sprays the vehicle statically to test the vehicle's sealing.

[0003] However, in real life, cars may vibrate while driving and drive at different tilt angles, which may cause the car seals to become loose and the gaps to become larger, which will have a certain impact on the car's sealing. However, since static spraying cannot effectively simulate the vehicle's daily driving conditions, the test data obtained is quite different from daily use, and the test effect is limited.

[0004] To this end, we proposed a new energy vehicle waterproof testing equipment. Summary of the invention

[0016] The beneficial effects achieved by the present invention using the above structure are as follows:

[0017] 1.

Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0037] like Figure 1-Figure 12 As shown, a new energy vehicle waterproof testing device of the present invention comprises a water reservoir 1, an adjusting mechanism 2 and a spraying mechanism 3. A base 4 is fixedly provided on the inner bottom wall of the water reservoir 1, the adjusting mechanism 2 is fixedly provided on the base 4, an inlet and outlet 5 is provided on the top of the water reservoir 1, the adjusting mechanism 2 moves through the inlet and outlet 5, and the spraying mechanism 3 is provided on the water reservoir 1 and is located above the inlet and outlet 5;

[0038] The adjusting mechanism 2 includes a driving component 21 and a supporting component 22. The driving component 21 is fixed on the base 4, and the supporting component 22 is arranged on the upper part of the driving component 21. The supporting component 22 includes a supporting plate 221, an elastic unit 222 and a parking platform 223. The supporting plate 221 is arranged on the upper part of the driving component 21, the elastic unit 222 is distributed on the upper part of the supporting plate 221, and the parking platform 223 is arranged on the elastic unit 222.

[0039] By cooperating with the driving assembly 21 and the supporting assembly 22 on the adjusting mechanism 2, the car on the supporting assembly 22 is driven to rotate, vibrate and tilt, simulating the vibration of the car during driving and driving at different tilt angles, making the waterproof test of the car more comprehensive.

[0040] like Figure 1-Figure 12 As shown, the driving assembly 21 includes a base 211, a support frame 212, a motor 213, a flip unit 215, a lifting unit 216 and a fixed column 219. The base 211 is fixedly arranged on the top of the base 4, the support frame 212 is set as a bent rod structure, and is fixedly distributed circumferentially on the top of the base 211. The side wall of the fixed column 219 is fixedly connected to the upper end of the support frame 212, and the fixed column 219 is provided with a mounting hole 217 along the axial direction. The motor 213 is fixedly arranged at the top center of the base 211, and the output end of the motor 213 is fixedly provided with a rotating shaft 218 through a coupling. The rotating shaft 218 rotates through the bearing and passes through the mounting hole 217 on the fixed column 219. The lifting unit 216 is arranged on the base 211, the flip unit 215 is arranged on the upper part of the lifting unit 216 and is connected to the rotating shaft 218, and the support plate 221 is arranged on the upper part of the flip unit 215.

[0041] like Figure 1-Figure 12As shown, the flip unit 215 includes a sleeve 2151, a rotating rod 2152, a toggle rod 2153 and a flip frame 2154. The sleeve 2151 is fixedly arranged at the top end of the rotating shaft 218 and is perpendicular to it. The rotating rod 2152 rotates and passes through the inside of the sleeve 2151. A fixed sleeve 2156 is fixedly arranged at one end of the toggle rod 2153. The fixed sleeve 2156 is fixedly connected to one end of the rotating rod 2152. The flip frame 2154 is trapezoidal, and the lower end of the flip frame 2154 is fixedly arranged at the end of the rotating rod 2152. The support plate 221 is horizontally fixedly arranged on the top of the flip frame 2154. The toggle rod 2153 is L-shaped, and the other end of the toggle rod 2153 is connected to the lifting unit 216.

[0042] By cooperating with the motor 213 and the flip unit 215, the flip unit 215 can be driven to rotate around the fixed column 219, thereby driving the support plate 221 and the parking platform 223 to rotate synchronously. The car rotates synchronously with the parking platform 223, so that multiple surfaces of the car can be sprayed with rain, thereby testing the waterproof performance of various parts of the car.

[0043] like Figure 1-Figure 12 As shown, the lifting unit 216 includes a cylinder 2161, an annular plate 2162, a support block 2163 and an annular shell 2164. The cylinder 2161 is fixedly arranged on the top of the base 211 and symmetrically distributed on the base 211. The annular plate 2162 is fixedly arranged on the output shaft of the cylinder 2161. The support block 2163 is circumferentially arranged on the top of the annular plate 2162. The annular shell 2164 is fixedly arranged on the upper part of the support block 2163. The annular plate 2162 and the annular shell 2164 are both sleeved on the outside of the fixed column 219. A guide sleeve 2165 is fixedly provided on one end of the support block 2163 facing the fixed column 219, and the guide sleeve 2165 is slidably sleeved on the outside of the fixed column 219. A concave annular opening 2166 is opened on the side of the annular shell 2164 facing the fixed column 219. The other end of the toggle rod 2153 extends into the interior of the annular shell 2164 through the annular opening 2166. A sliding ball 2157 is fixedly provided on the end of the toggle rod 2153 extending into the annular shell 2164, and the sliding ball 2157 is movably arranged in the annular shell 2164.

[0044] By cooperating with the lifting unit 216 and the flipping unit 215, the rotation of the flipping frames 2154 at both ends of the rotating rod 2152 is realized. Therefore, by controlling the extension and retraction of the cylinder 2161, the inclination of the support plate 221 can be controlled, and then the inclination of the parking platform 223 and the car can be controlled, which facilitates the simulation of the waterproof condition of the car when driving on an inclined road, and further improves the test effect.

[0045] like Figure 1-Figure 12As shown, the driving assembly 21 also includes an auxiliary vibration unit 214, which is arranged on one side of the flip frame 2154 and is intermittently connected to the bottom of the parking platform 223. The auxiliary vibration unit 214 includes a cam 2141, a transmission shaft 2142, a driven gear 2143, a toothed disc 2144, a vertical rod 2145 and a collision device 2146. One end of the transmission shaft 2142 is rotatably connected to the bottom end of the flip frame 2154 through a bearing. The transmission shaft 2142 is coaxial with the rotating rod 2152, and the driven gear 2143 is connected to the vertical rod 2145. The wheel 2143 is fixedly connected to the other end of the transmission shaft 2142, the cam 2141 is fixed on the transmission shaft 2142, the impactor 2146 passes through the support plate 221 from top to bottom, and its top is connected to the bottom of the parking platform 223, the bottom of the impactor 2146 contacts the cam 2141, the bottom end of the vertical rod 2145 is fixed on the support frame 212, and is located around the annular plate 2162, the toothed disc 2144 is fixed on the top of the vertical rod 2145, and the driven gear 2143 is meshed with the toothed disc 2144.

[0046] The auxiliary vibration unit 214 is provided to intermittently collide with the parking platform 223, causing the parking platform 223 to vibrate, simulating the vibration that may occur during the driving of the car, making the waterproof test more realistic and improving the test effect.

[0047] like Figure 1-Figure 12 As shown, the collision device 2146 includes a slide bar 461, a baffle 462, a roller 463, a compression spring 464, a sleeve 465 and a collision block 466. The slide bar 461 slides up and down and passes through the support plate 221. The baffle 462 is fixed at the bottom of the slide bar 461. The roller 463 is installed at the bottom of the baffle 462 and is in rolling contact with the cam 2141. The compression spring 464 is slidably sleeved on the slide bar 461 and is in contact between the top of the baffle 462 and the bottom of the support plate 221. The top of the sleeve 465 is fixedly connected to the bottom of the parking platform 223. The slide bar 461 slides from the bottom of the sleeve 465 into the interior of the sleeve 465. The collision block 466 is fixed in the sleeve 465, and the top of the slide bar 461 intermittently contacts the collision block 466.

[0048] Under the rebound force of the compression spring 464, the roller 463 is always tightly fitted with the cam 2141, and the slide rod 461 always moves up and down under the limitation of the sleeve 465 without deviation. Therefore, when the cam 2141 rotates, the roller 463 will oscillate up and down, and then the slide rod 461 will intermittently collide with the collision block 466.

[0049] like Figure 1-Figure 12As shown, the elastic unit 222 includes an upper limit sleeve 2221, a lower limit sleeve 2222 and a support spring 2223. The upper limit sleeve 2221 is fixed at the bottom of the parking platform 223, and the lower limit sleeve 2222 is fixed at the top of the support plate 221 and is located directly below the upper limit sleeve 2221. Both ends of the support spring 2223 are respectively fixed inside the upper limit sleeve 2221 and the lower limit sleeve 2222.

[0050] By the cooperation of the auxiliary vibration unit 214 and the flip unit 215, when the flip frame 2154 rotates around the fixed column 219, the transmission shaft 2142 is driven to rotate around the fixed column 219, so that the driven gear 2143 engages and rotates on the toothed disc 2144, and the transmission shaft 2142 rotates, thereby driving the cam 2141 to rotate. Under the action of the clamping spring 464, the roller 463 is always close to the cam 2141. Therefore, when the cam 2141 rotates, the roller 463, with the cooperation of the clamping spring 464, will reciprocate up and down, so that the slide bar 461 moves back and forth up and down, and then the top end of the slide bar 461 intermittently hits the collision block 466, causing the deformation of the support spring 2223, causing the sleeve 465 and the parking platform 223 to vibrate, and then causing the car to vibrate, thereby simulating the vibration that may occur during the driving of the car, making the waterproof test more in line with reality and further improving the test effect.

[0051] like Figure 1-Figure 12 As shown, the top of the parking platform 223 is detachably connected to a limit plate 2231, which is L-shaped. A through hole 2232 is provided on the limit plate 2231, and a plurality of threaded holes 2233 are distributed on the top of the parking platform 223. Bolts pass through the through holes 2232 and are connected to the corresponding threaded holes 2233 to fix the limit plate 2231 on the parking platform 223. The L-shaped limit plate 2231 clamps the wheels of the car to limit the movement of the wheels of the car in the front, back, left and right directions. When the parking platform 223 rotates and tilts, the car can be prevented from sliding off the parking platform 223, thereby ensuring the smooth progress of the car waterproof test. When in use, first drive the car onto the parking platform 223, and then fix the limit plate 2231 on the wheels of the car.

[0052] like Figure 1-Figure 12As shown, the spraying mechanism 3 includes an arc-shaped water pipe 31, both ends of which are connected with vertical water pipes 32, the vertical water pipe 32 is fixedly connected to the water reservoir 1, and the vertical water pipe 32 is connected to an external water pump, the arc-shaped water pipe 31 is located above the parking platform 223, and the vertical water pipe 32 is located on the left and right sides of the parking platform 223, and nozzles are connected in series on the arc-shaped water pipe 31 and the vertical water pipe 32, and the nozzles are all facing the direction of the parking platform 223. Through the arc-shaped water pipe 31, water can be sprayed on the top of the car on the parking platform 223, and water can be sprayed on the side of the car on the parking platform 223, and the parking platform 223 can rotate, so the arc-shaped water pipe 31 and the vertical water pipe 32 can spray water on all sides of the car.

[0053] like Figure 1-Figure 12 As shown, the parking platform 223 and the support plate 221 are both movably located at the inlet and outlet 5, and two sets of long boards are placed on the top of the water reservoir 1, one end of the long board is placed on the top of the water reservoir 1, and the other end of the long board is placed on the parking platform 223. The placed long boards can facilitate the car to drive to the parking platform 223, and the long boards can be removed during testing; the water reservoir 1 can collect the sprayed water for recycling.

[0054] When in use, the water reservoir 1 is built under the ground, and its top is flush with the ground. The vertical water pipe is connected to the external water pump. Then the car drives along the long board to the parking platform 223, and then the L-shaped limiting plate 2231 is fixed to the parking platform 223 by bolts to limit the four wheels of the car to prevent the car from sliding on the parking platform 223.

[0055] Then, the external water pump is started to pump water into the arc-shaped water pipe 31 and the vertical water pipe 32, and the water is sprayed onto the car from the nozzle to simulate the rainy scene. The motor 213 is started to drive the rotating shaft 218 to rotate, and then the sleeve 2151 is driven to rotate, and then the rotating rod 2152 is driven to rotate, and then the turning frame 2154 is driven to rotate, and then the support plate 221 and the parking platform 223 are driven to rotate synchronously. The car rotates synchronously with the parking platform 223, so that multiple surfaces of the car can be sprayed with rain, so that the waterproof performance of various parts of the car can be tested; the tested water flows back to the reservoir 1 and can be recycled;

[0056] At the same time, when the flip frame 2154 rotates around the fixed column 219, it also drives the transmission shaft 2142 to rotate around the fixed column 219, thereby making the driven gear 2143 mesh and rotate on the toothed disc 2144, and the transmission shaft 2142 rotates, thereby driving the cam 2141 to rotate. Under the action of the compression spring 464, the roller 463 is always close to the cam 2141. Therefore, when the cam 2141 rotates, the roller 463, with the cooperation of the compression spring 464, will reciprocate up and down, making the slide bar 461 reciprocate up and down, thereby making the top end of the slide bar 461 intermittently hit the collision block 466, causing the deformation of the support spring 2223, thereby causing the sleeve 465 and the parking platform 223 to vibrate, and then causing the car to vibrate, thereby simulating the vibration that occurs during the driving of the car, making the waterproof test more realistic and further improving the test effect;

[0057] At the same time, the cylinder 2161 is started to drive the annular plate 2162 to rise, thereby driving the support block 2163 to rise, thereby driving the annular shell 2164 to rise. Since the sliding ball 2157 moves in the cavity of the annular shell 2164, when the annular shell 2164 rises, the sliding ball 2157 is driven to slide in the annular shell 2164, thereby driving the toggle rod 2153 connected thereto to rotate. The toggle rod 2153 is L-shaped, so the rotation of the toggle rod 2153 drives the rotating rod 2152 to rotate, thereby driving the flip frames 2154 at both ends of the rotating rod 2152 to rotate. Thereby, the support plate 221 on the flip frame 2154 is driven to rotate. Therefore, by controlling the extension and retraction of the cylinder 2161, the inclination of the support plate 221 can be driven, and then the inclination of the parking platform 223 and the car can be controlled, so as to simulate the waterproof condition of the car when driving on an inclined road, further improving the test effect. Moreover, when the parking platform 223 continues to rotate, the inclination of the parking platform 223 can still be adjusted. Therefore, the continuous rotation of the car, the continuous vibration of the car and the tilting of the car can be carried out at the same time, and the waterproof test effect is better and more in line with reality.
