Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging piles, in particular to an environment simulation test device for charging piles. BACKGROUND

[0002] With the rapid development of the electric vehicle industry, the performance reliability and environmental adaptability of charging piles, as key supporting infrastructure, have attracted widespread attention. Charging piles, especially the exposed charging gun, need to withstand various complex natural environments throughout the year, such as wind and rain, temperature changes, etc. Among them, the wind and rain environment is one of the main factors leading to charging gun failure. Rainwater may penetrate into the gun body under the driving force of wind, causing safety hazards such as insulation performance degradation, short circuit, poor contact, etc., seriously affecting charging safety and service life. Therefore, before the charging pile is put into actual use, simulating its working state in different wind and rain environments and conducting strict sealing performance and insulation performance tests are crucial to ensure product quality and user safety.

[0003] Traditional environmental test methods mainly focus on single factors, such as simple spray tests to simulate rainfall or fans with fixed wind direction and fixed wind volume to simulate wind power. However, the wind and rain phenomena in actual natural environments are much more complex: wind power is not constant but often presents gust characteristics; wind direction is not fixed but uncertain. Such dynamic changing wind and rain conditions pose more severe challenges to the sealing and insulation performance of charging guns.

[0004] Therefore, it is necessary to develop an environment simulation test device for charging piles that can highly simulate real dynamic wind and rain environments, especially reproduce gust effects and wind direction changes, to improve the environmental adaptability of charging piles. SUMMARY

[0005] The technical solution of the present application is: an environment simulation test device for charging piles, comprising a test box body with an open top, a charging gun arranged inside the test box body, a mounting block, a rotating shaft, a fan, a spray assembly, and a wind power adjusting assembly. The top of one side of the test box body in the width direction is provided with a spray assembly for simulating rain weather. The inner wall of the test box body provided with the spray assembly is horizontally symmetrically provided with mounting blocks. The mounting blocks are rotatably installed with a mounting frame through a rotating shaft. The mounting frame is located below the spray assembly. The two sides of the mounting frame are respectively provided with a fan for simulating a wind environment and a wind power adjusting assembly for adjusting the wind power blown by the fan to simulate a gust environment. The wind power adjusting assembly comprises a wind power adjusting wheel, a second driving motor, and a driving wheel. The wind power adjusting wheel is installed on the mounting frame and located on the opposite side of the fan. Ventilation grooves are arranged in a circumferential ring array on the wind power adjusting wheel. The second driving motor is installed on the mounting frame. The output shaft of the second driving motor is connected with the driving wheel. The driving wheel is engaged with the wind power adjusting wheel.

[0006] Furthermore, the ventilation slots on the wind-powered regulating wheel in the ring array are arranged with slots of different specifications arranged alternately.

[0007] Furthermore, this device is also equipped with a first angle adjustment component to adjust the fan blowing angle to simulate the change of wind blowing angle. The first angle adjustment component includes a first drive motor, a turntable, a drive rod, and a transmission frame. The first drive motor is installed on the side wall along the length of the test chamber. The output shaft of the first drive motor is connected to the turntable. A drive rod is provided at the centrifugal part of the turntable. A transmission frame is fixedly installed on a rotating shaft that passes through the mounting block. A sliding groove is provided on the transmission frame, and the drive rod slides in the sliding groove.

[0008] Furthermore, the spray assembly includes a U-shaped mounting bracket mounted on the test chamber and a sprayer mounted on the U-shaped mounting bracket. The sprayer is inclined above the mounting frame, and the nozzle of the sprayer is inclined downward and faces the charging gun.

[0009] Furthermore, a moving component for driving the charging gun to move horizontally is also provided on one side of the test box in the width direction. The moving component includes two mounting brackets, a first electric lead screw, a first guide rod, a connecting block, and a U-shaped bracket. The two mounting brackets are respectively installed on the top of the two sides in the length direction of the test box. The first electric lead screw is rotatably installed on one mounting bracket and the first guide rod is rotatably installed on the other mounting bracket. The first electric lead screw and the first guide rod are arranged in parallel, and a connecting block is movably connected to both the first electric lead screw and the first guide rod. A U-shaped bracket is installed between the two connecting blocks.

[0010] Furthermore, a lifting assembly for driving the charging gun to move up and down is provided inside the frame. The lifting assembly includes a second electric lead screw, a second guide rod, and a lifting block. The second electric lead screw and the second guide rod are arranged parallel to each other inside the frame, and the lifting block is movably arranged between the second electric lead screw and the second guide rod.

[0011] Furthermore, the device is also provided with a second angle adjustment component for adjusting the angle of the charging gun. The second angle adjustment component includes a hinge block, a worm gear, a worm wheel, and a gantry frame. The hinge block is hinged on the lifting block. Two rods on the hinge block rotatably pass through the lifting block, and at least one rod end is connected to a worm wheel. A worm gear that meshes with the worm wheel is rotatably provided on the lifting block. The end of the hinge block away from the lifting block is connected to the gantry frame.

[0012] Furthermore, a clamping assembly for clamping and fixing the charging gun is provided inside the gantry frame. The clamping assembly includes a third electric lead screw and a third guide rod horizontally arranged inside the gantry frame. The third electric lead screw and the third guide rod are arranged side by side, one above the other. Two clamping blocks are movably arranged on the third electric lead screw and the third guide rod. When the two clamping blocks come close to each other, they clamp the charging gun.

[0013] Furthermore, each clamping block is slidably equipped with a pull rod, which is perpendicular to the plane formed by the third electric lead screw and the third guide rod, and a shielding cloth is provided between the pull rods.

[0014] The beneficial effects are as follows: 1. By setting up a wind power adjustment component consisting of a second drive motor, a drive wheel, and a wind power adjustment wheel, and adopting a design with ventilation slots of different specifications arranged alternately, the stable wind power generated by the fan is periodically modulated. When the large ventilation slot is aligned, it simulates strong gusts, and when the small ventilation slot is aligned, it simulates weak intermittent winds, thus efficiently and reliably simulating the fluctuating gust environment in nature, greatly improving the realism and severity of the test.

[0015] 2. The mounting frame and fan assembly are driven to swing as a whole by the cooperation of the first drive motor, turntable, drive rod and transmission frame, so that the direction of the wind blowing towards the charging gun (and the direction of the rainwater mixed in) is no longer fixed, but achieves reciprocating changes within a certain angle range. This simulates the instability of natural wind direction, and can test the sealing and insulation performance of the charging gun under the impact of wind and rain at different angles, with more comprehensive test coverage.

[0016] 3. The charging gun moves horizontally through the cooperation of the first electric lead screw, the first guide rod, and the connecting block; it moves vertically through the cooperation of the second electric lead screw, the second guide rod, and the lifting block; and the charging gun's elevation angle is adjusted by the cooperation of the worm gear, worm wheel, hinge block, and gantry frame. This allows for multi-dimensional adjustment of the charging gun's horizontal position, lifting height, and elevation angle, thus simulating the charging gun's rainproof performance under different installation positions and usage postures.

[0017] 4. By incorporating a pull-out rod and a protective cloth, this design conveniently simulates the scenario of adding a rainproof shield to the charging gun connection point during actual installation. This protects the testing equipment from direct rainwater intrusion and damage, ensuring testing safety, and also verifies the actual effectiveness of the added protective measures, making it a practical function.

Detailed Implementation

[0028] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Example: An environmental simulation testing device for charging piles, such as Figure 1 as well as Figures 6-9As shown, the test chamber 1 includes an open top, a charging gun 100 inside the test chamber 1, a mounting block 101, a rotating shaft 102, a fan 24, a spray assembly, and a wind speed adjustment assembly. A spray assembly for simulating rainy weather is located on the top right side of the test chamber 1. Mounting blocks 101 are symmetrically arranged horizontally on the inner right side of the test chamber 1. A rotating shaft 102 is rotatably mounted on each mounting block 101, and a mounting frame 20 is rotatably mounted between the two mounting blocks 101 via the rotating shaft 102. Fixedly connected to the rotating shaft 102, the mounting frame 20 is located below the spray assembly. On both sides of the mounting frame 20 are respectively provided a fan 24 simulating a windy environment and a wind force adjustment component to adjust the airflow from the fan 24 to simulate a gust of wind. The wind force adjustment component includes a wind force adjustment wheel 21, a second drive motor 22, and a drive wheel 23. The wind force adjustment wheel 21 is mounted on the mounting frame 20 and located on the opposite side of the fan 24. The wind force adjustment wheel 21 has a disc-shaped structure and is rotatably mounted on the mounting frame 20 via the rotating shaft. Several ventilation slots 211 are arranged in a circular array along its circumference, penetrating both end faces, serving as ventilation channels. These ventilation slots 211 consist of two specifications: large ventilation slots with a larger cross-sectional area and small ventilation slots with a smaller cross-sectional area, arranged alternately and at equal intervals. In use, the air generated by the fan 24 passes through the ventilation slots 211 on the rotating wind force adjustment wheel 21 and blows towards the charging gun 100. When the large ventilation duct rotates to face the charging gun 100, the wind resistance is low and the wind force is high; when the small ventilation duct rotates to face the charging gun 100, the wind resistance is high and the wind force is low, thus simulating gusts. A second drive motor 22 is installed on the mounting frame 20. A drive wheel 23 is connected to the output shaft of the second drive motor 22. The drive wheel 23 meshes with the wind force regulating wheel 21. The second drive motor 22 is preferably a servo motor. The second drive motor 22 drives the wind force regulating wheel 21 to perform deceleration motion through the drive wheel 23, thereby realizing the periodic and pulsating modulation of the wind force blowing towards the charging gun 100.

[0030] like Figure 1 and Figure 6 As shown, the spray assembly includes a U-shaped mounting bracket 15 installed on the test chamber 1 and a sprayer 16 installed on the U-shaped mounting bracket 15. A water supply pipe is provided between the sprayer 16 and the bottom of the inner side of the test chamber 1. The sprayer 16 is inclined above the mounting frame 20, and the nozzle of the sprayer 16 is inclined downward and facing the charging gun 100. This is to facilitate the simulation of rainwater washing the charging gun 100. The washed rainwater falls into the test chamber 1 and is transported to the sprayer 16 through the water pump and the water supply pipe, thereby realizing the recycling of water resources.

[0031] During use, the sprayer 16 tilts downwards to spray water, simulating rainy weather, with the water flow hitting the charging gun 100 area. Simultaneously, the fan 24 is powered on, generating a stable base wind that blows towards the charging gun 100, simulating continuous wind during rain. Under the influence of the fan 24, rainwater is blown towards the charging gun 100, allowing for testing of the charging gun 100's insulation performance and sealing performance under windy and rainy conditions. When simulating gusts of wind in nature, the second drive motor 22 is energized, driving the drive wheel 23 to rotate, which in turn drives the meshing wind-regulating wheel 21 to rotate at a constant speed. The ventilation slots 211 of different sizes in a ring array on the wind-regulating wheel 21 will periodically align with the charging gun 100. When the large ventilation slot 211 is aligned with the charging gun 100, most of the wind generated by the fan 24 is blown towards the charging gun 100 through the large ventilation slot 211, and the rainwater sprayed by the sprinkler 16 is also blown towards the charging gun 100. This allows for testing the insulation of the charging gun 100 under "gust" conditions. Performance and sealing performance under strong wind conditions; when the small ventilation slot 211 is used to charge the charging gun 100, the wind force passing through the small ventilation slot 211 is weakened due to the large wind resistance of the small ventilation slot 211, thus reducing the wind force blowing towards the charging gun 100, simulating the "weak wind" or "still wind" intervals between gusts; by continuously rotating the wind force regulating wheel 21, the periodic and pulsating modulation of the wind force blowing towards the charging gun 100 can be achieved, thereby highly realistically simulating the stability of the charging gun 100 in a gust environment; in addition to the spraying operation of the sprayer 16, the sealing and insulation performance of the charging gun 100 under the combined gust and rain environment can also be tested.

[0032] like Figures 6-8 As shown, this device is also equipped with a first angle adjustment component to adjust the blowing angle of the fan 24 to simulate the change of the blowing angle of the wind. The first angle adjustment component includes a first drive motor 17, a turntable 18, a drive rod 181 and a transmission frame 19. The first drive motor 17 is installed on the side wall of the test chamber 1 along its length. The output shaft of the first drive motor 17 is connected to the center of the turntable 18 through a coupling. The drive rod 181 is provided at the centrifugal part of the turntable 18 facing away from the first drive motor 17. The transmission frame 19 is fixedly installed on a rotating shaft 102 that rotates through the mounting block 101. The transmission frame 19 has a sliding groove 191. The drive rod 181 extends into the sliding groove 191 and can slide along it. When the first drive motor 17 drives the turntable 18 to rotate, the drive rod 181 slides in the sliding groove 191 and drives the transmission frame 19 to swing back and forth, thereby driving the rotating shaft 102 and the mounting frame 20 fixed thereto to swing back and forth around the axis of the rotating shaft 102 within a certain angle.

[0033] To simulate the instability of wind direction, the first drive motor 17 is energized, which drives the turntable 18 to rotate. The drive rod 181 on the turntable 18 then makes a circular motion and slides in the groove 191 of the transmission frame 19. This motion converts the circular motion into the reciprocating oscillation of the transmission frame 19, and drives the entire mounting frame 20 (along with the fan 24 and wind power adjustment wheel 21 on it) to oscillate back and forth around the axis of the shaft 102 within a certain angle. This makes the wind direction (whether continuous wind or gust) blowing towards the charging gun 100 no longer fixed, but has an angle change, thus more realistically simulating the blowing effect of natural wind. Due to the spraying operation of the sprinkler 16, the wind blowing towards the charging gun 100 is mixed with rainwater, thus testing the sealing and insulation performance of the charging gun 100 under the impact of rainwater from different directions.

[0034] like Figures 1-9 As shown, a moving assembly for driving the charging gun 100 to move horizontally is also provided on the left side of the test chamber 1. The moving assembly includes two mounting brackets 3, a first electric lead screw 32, a first guide rod 33, a connecting block 31, and a U-shaped bracket 2. The two mounting brackets 3 are respectively installed on the top of the front and rear sides of the test chamber 1. The first electric lead screw 32 is rotatably mounted on one mounting bracket 3, and the first guide rod 33 is rotatably mounted on the other mounting bracket 3. The first electric lead screw 32 includes a first lead screw rotatably mounted on the side mounting bracket 3 and a guide rod 33 fixedly mounted on the other mounting bracket 3. The first motor on the side mounting bracket 3 has its output shaft connected to one end of the first lead screw. The first electric lead screw 32 and the first guide rod 33 are arranged in parallel, and both the first electric lead screw 32 and the first guide rod 33 are movably connected to a connecting block 31. The first lead screw thread of the first electric lead screw 32 passes through the connecting block 31, and the first guide rod 33 slides through the connecting block 31. A U-shaped bracket 2 is installed between the two connecting blocks 31. When the first lead screw rotates, the U-shaped bracket 2 and the connecting block 31 move horizontally along the first guide rod 31.

[0035] like Figure 2 and Figure 3 As shown, a lifting assembly for driving the charging gun 100 to move up and down is provided inside the U-shaped frame 2. The lifting assembly includes a second electric lead screw 4, a second guide rod 41, and a lifting block 5. The second electric lead screw 4 and the second guide rod 41 are arranged parallel to each other inside the U-shaped frame 2. The second electric lead screw 4 includes a second lead screw rotatably arranged inside the U-shaped frame 2 and a second motor connected to one end of the second lead screw. Two second guide rods 41 are provided and symmetrically arranged on both sides of the U-shaped frame 2 with the second lead screw as the center. The lifting block 5 is movably arranged between the second electric lead screw 4 and the second guide rod 41. The second lead screw thread passes through the lifting block 5, and the second guide rod 41 slides through the lifting block 5. When the second lead screw rotates, the lifting block 5 moves vertically up and down along the second guide rod 41.

[0036] The first electric lead screw 32 rotates to drive the connecting block 31 and the frame 2 to move horizontally along the length of the test box 1. The second electric lead screw 4 rotates to drive the lifting block 5 to move vertically within the frame 2. Through horizontal and vertical movement, the position of the charging gun 100 on the horizontal and vertical planes can be precisely adjusted to test the rainproof performance of the charging gun 100 when it moves.

[0037] like Figure 3 As shown, the device is also provided with a second angle adjustment assembly for adjusting the angle of the charging gun 100°. The second angle adjustment assembly includes a hinge block 6, a worm 7, a worm wheel 8, and a gantry frame 9. The lifting block 5 is hinged to the hinge block 6. Two rods on the hinge block 6 rotatably pass through the lifting block 5, and at least one end of the rod is connected to the worm wheel 8. At least one outer wall of the lifting block 5 is rotatably provided with a worm 7 that meshes with the worm wheel 8 through a bearing seat. The end of the hinge block 6 away from the lifting block 5 is connected to the gantry frame 9.

[0038] like Figure 3 and Figure 4 As shown, a clamping assembly for holding and fixing the charging gun 100 is provided inside the gantry frame 9. The clamping assembly includes a third electric lead screw 10 and a third guide rod 11 horizontally arranged inside the gantry frame 9. The third electric lead screw 10 and the third guide rod 11 are arranged side by side, one above the other. Two clamping blocks 12 are movably arranged on the third electric lead screw 10 and the third guide rod 11. The lead screw portion of the third electric lead screw 10 is threadedly connected to the clamping block 12, and the third guide rod 11 is slidably connected to the clamping block 12. When the two clamping blocks 12 approach each other, they clamp the charging gun 100. The third electric lead screw 10 includes a third motor and a third lead screw connected to the output shaft of the third motor. The third lead screw is a bidirectional lead screw. The rotation of the third lead screw drives the two clamping blocks 12 to approach or move away from each other along the third guide rod 11, thereby realizing the clamping and release of the charging gun 100.

[0039] The worm gear 7 drives the worm wheel 8 to rotate, which in turn causes the hinge block 6 and the gantry 9 to rotate around the hinge point between the hinge block 6 and the lifting block 5, thereby adjusting the elevation angle of the charging gun 100 and testing the rainproof performance of the charging port of the charging gun 100 at different elevation angles.

[0040] like Figure 3 and Figure 4 As shown, each clamping block 12 is slidably provided with a pull rod 13. The pull rod 13 is perpendicular to the plane formed by the third electric lead screw 10 and the third guide rod 11. A shielding cloth 14 is provided between the pull rods 13. The shielding cloth 14 is made of a material with elasticity.

[0041] By pulling the lever 13, the shielding cloth 14 is placed over the interface of the charging gun 100 to simulate preventing spray water from directly splashing into the electrical interface of the charging gun 100 in a specific test project, so as to conduct targeted protection tests.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
