[0034] Example 1

[0035] Reference Figures 1 to 5 and Figure 8 , which is the first embodiment of the present invention, provides an electric vehicle high-power charging compatibility observation mechanism that is easy to use for belt changing.

[0036] Specifically, the main assembly 100 includes a testing device 101, a connecting platform 102 provided inside the testing device 101, and a mounting rail 103 provided on the outer wall of the connecting platform 102;

[0037] The connection assembly 200 provided on the outer wall of the mounting rail 103 includes a mounting base 201, an end surface of the mounting base 201 is provided with a connector 202 and the connector 202 is used to connect to the charging connector of the electric vehicle;

[0038] The connector 202 is also provided with an adjustment component for driving a movable component disposed on the inner wall of the connector 202. The movable component includes a plurality of limit blocks 2044 disposed in an array on the inner wall of the connector 202. The limit blocks 2044 are driven by the adjustment component to contact the outer wall of the charging connector. The adjustment component is also used to control the opening of the heat dissipation channel within the connector 202 for heat dissipation.

[0039] The moving block 301 provided on the mounting base 201 is sleeved on the outer wall of the mounting guide rail 103 and slides along the mounting guide rail 103 . The mounting base is fixed to the outer wall of the mounting guide rail 103 through regulation by an internal control component.

[0040] Among them, the slider 2011 at the bottom of the mounting base 201 cooperates with the moving block 301, so that the mounting base 201 as a whole can slide on the mounting guide rail 103, and at the same time, the control component inside the moving block 301 can be adjusted so that the moving block 301 and the mounting guide rail 103 are clamped to fix the mounting base 201 above the connecting platform 102, and the charger connector of the electric vehicle is clamped and fixed through the connecting head 202. The moving component arranged inside the connecting head 202 is adjusted by the adjusting component to adapt to charging connectors of different sizes. When performing high-power charging tests, the heat dissipation channel can be controlled to open through the adjusting component to dissipate the heat inside the connecting head 202, thereby extending the test time.

[0041] The mounting base 201 can be quickly replaced by the moving block 301, and the connector 202 on the surface of the mounting base 201 can adapt to charging interfaces of different sizes and models through the internal moving components, thereby achieving test compatibility and quick replacement.

[0042] Example 2

[0043] Reference Figures 1 to 7 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0044] Specifically, the adjusting component includes a first worm 203, which is installed inside the connecting head 202. A rotating rod 2032 is provided on the inner wall of the first worm 203, and the end of the rotating rod 2032 extends to the outer wall of the connecting head 202 for user operation. The rotating rod 2032 is located inside the connecting head 202 and a second joint 2033 is fixed at one end. The second joint 2033 is engaged with the first joint 2031 fixed on the outer wall of the first worm 203. When the first joint 2031 is engaged with the second joint 2033, the first worm 203 is driven to rotate by the rotating rod 2032.

[0045] Among them, the first worm gear 203 is installed in the space at the bottom of the connecting head 202, and can rotate while being restricted on both sides and unable to move. The first joint 2031 on the outside of the first worm gear 203 is affected by the second joint 2033. The second joint 2033 is in a locked state with the first joint 2031 in the initial state. Therefore, when the rotating rod 2032 rotates, it drives the first worm gear 203 to rotate. When pushing the rotating rod 2032, the rotating rod 2032 will drive the second joint 2033 at the bottom to separate from the first joint 2031. At this time, the rotation of the rotating rod 2032 cannot affect the first worm gear 203.

[0046] Preferably, a disc 204 is provided inside the connecting head 202 and a half worm gear 2043 is provided at the end of the disc 204. The half worm gear 2043 is engaged with the first worm 203. When the first worm 203 rotates, it drives the disc 204 to rotate inside the connecting head 202. A third joint 2034 is fixed to the other end of the second joint 2033 and a second worm 2036 is provided on the outer wall of the third joint 2034. A fourth joint 2037 is provided on the outer wall of the second worm 2036 and a first elastic member 2035 is provided on the outer wall of the fourth joint 2037 for separating the third joint 2034 and the fourth joint 2037. When the third joint 2034 is pushed by the rotating rod 2032 and engaged with the fourth joint 2037, it drives the second worm 2036 to rotate.

[0047] Among them, Figure 6 It can be seen that a half worm gear 2043 is fixed to the bottom of the disc 204 and the axis of the half worm gear 2043 and the disc 204 are sleeved on the rotating shaft on the surface of the mounting base 201. The first worm 203 is meshed with the half worm gear 2043. In the initial state, when the rotating rod 2032 drives the first worm 203 to rotate, the first worm 203 drives the disc 204 to rotate inside the connecting head 202.

[0048] The second joint 2033 and the third joint 2034 are a whole and are arranged relative to each other. When the rotating rod 2032 rotates, the second joint 2033 and the third joint 2034 are synchronously driven to rotate. The second worm 2036 is installed inside the connecting head 202 and does not move. At the same time, the fourth joint 2037 arranged on the outer wall of the second worm 2036 is installed with a first elastic member 2035 on the outer surface. The first elastic member 2035 is used to push the second joint 2033 to engage with the first joint 2031 in the initial state. When the second worm 2036 needs to rotate, the rotating rod 2032 is pushed to make the third joint 2034 overcome the elastic force of the first elastic member 2035 and engage with the fourth joint 2037. At this time, the second worm 2036 is driven to rotate by the rotating rod 2032.

[0049] The outer wall of the second worm 2036 is meshed with the first worm wheel 2038 and the outer wall of the first worm wheel 2038 is coaxially connected to the output gear 2039. The output gear 2039 is meshed with the rack 20310 provided on the inner wall of the connecting head 202 and controls the rack 20310 to rise and fall.

[0050] Among them, the first worm gear 2038 is coaxially connected to the output gear 2039 and there is a distance between them. The rotation of the second worm 2036 drives the first worm gear 2038 to rotate, and further transmits it to the output gear 2039 to rotate, thereby realizing the control of the lifting and lowering of the rack 20310.

[0051] The end of the rack 20310 is connected to a connecting ring 20311 and a baffle 20312 is arranged in an array at the end of the connecting ring 20311. The baffle 20312 is located in the vent 2021 opened on the inner wall of the connecting head 202. The baffle 20312 rises and falls in the connecting head 202 with the connecting ring 20311 to control the opening and closing of the vent 2021.

[0052] Among them, the top of the rack 20310 and the connecting ring 20311 are fixedly connected together, and the connecting ring 20311 is driven to move inside the connecting head 202 by the lifting and lowering of the rack 20310. At the same time, a baffle 20312 is also provided on the surface of the connecting ring 20311, and the baffle 20312 is initially inside the vent 2021 and blocks the vent 2021. When the internal heat needs to be dissipated, the connecting ring 20311 is driven to descend by the second worm 2036, so that the baffle 20312 can be moved down synchronously and the vent 2021 can be opened.

[0053] The end surface array of the disk 204 is provided with a sliding groove 2041 and the end of the sliding groove 2041 is provided with a limiting block 2044. The limiting block 2044 slides on the inner wall of the slideway 2022 provided on the inner wall of the connector 202.

[0054] Among them, the limit block 2044 is restricted by the slide 2022 on the inner wall of the connecting head 202 and can only slide inside the slide 2022. At the same time, the bottom slide column of the limit block 2044 extends to the inside of the slide groove 2041 on the surface of the disc 204. Therefore, when the disc 204 is driven by the first worm 203 to rotate, the slide groove 2041 cooperates with the slide column to drive the limit block 2044 to move inside the slide 2022, thereby realizing the inward movement of the limit block 2044 to fix the charging interface.

[0055] Preferably, an ion fan 205 is installed on the inner wall of the vent 2021 , an air duct 2051 is opened on the inner wall of the ion fan 205 , and a grid 2052 is arranged on the inner wall of the air duct 2051 , and an electric wire 2053 is also arranged on the outer wall of the air duct 2051 .

[0056] When heat dissipation is required, a high voltage is applied to the wire 2053, the air is ionized by high-voltage corona discharge, and a directional airflow is formed by the momentum transfer of ions and neutral molecules. The air is blown to the outside through the air duct 2051 and the hot air inside is discharged outward.

[0057] In summary, when in use, the charging port of the car needs to be fixed first. At this time, it is in the initial state. The second connector 2033 is pushed by the first elastic member 2035 to engage with the first connector 2031. When the rotating rod 2032 rotates, the first connector 2031 and the second connector 2033 are engaged to drive the first worm gear 203 to rotate. At this time, the baffle 20312 is still inside the vent 2021 to block the vent 2021 and the ion fan 205 is not started.

[0058] The first worm 203 is driven to rotate by the rotating rod 2032. Since the half worm gear 2043 on the lower surface of the disc 204 is engaged with the first worm 203, the disc 204 rotates at this time, and the slide groove 2041 on the surface of the disc 204 drives the limit block 2044 to slide inside the slide 2022. Finally, the limit block 2044 moves inward to clamp and fix the charging interface.

[0059] When conducting a high-power charging compatibility test, a large amount of heat will be generated inside the connector 202. In order to ensure the continuity of the test, the rotating rod 2032 is pushed axially at this time, so that the second connector 2033 and the third connector 2034 move axially, and the second connector 2033 is separated from the first connector 2031. At the same time, the third connector 2034 overcomes the elastic force of the first elastic member 2035 and engages with the fourth connector 2037, so that the rotating rod 2032 is linked with the second worm 2036. At this time, the rotation of the rotating rod 2032 only drives the second worm 2036 to rotate, and because the worm gear has self-locking properties, when the rotating rod 2032 does not drive the first worm 203 to rotate, the first worm 203 realizes a limiting effect on the limit block 2044. After the first worm 203 is separated from the rotating rod 2032, the disc 204 no longer rotates with the rotating rod 2032.

[0060] Through the engagement of the third joint 2034 and the fourth joint 2037, the rotating rod 2032 drives the second worm 2036 to rotate, the second worm 2036 engages the first worm gear 2038, and the first worm gear 2038 coaxially drives the output gear 2039 to rotate, and the output gear 2039 engages with the rack 20310, driving the rack 20310 to move downward.

[0061] The connecting ring 20311 at the end of the rack 20310 drives the baffle 20312 to descend synchronously, so that the baffle 20312 is separated from the vent 2021, and the vent is opened.

[0062] At this time, a high voltage is applied to the wire 2053, and the ion fan 205 ionizes the air through high-voltage corona discharge. The momentum transfer between ions and neutral molecules forms a directional airflow, which blows air to the outside through the air duct 2051 and the grille 2052, driving the hot air inside the equipment to be discharged through the vent 2021 to achieve heat dissipation.

[0063] Example 3

[0064] Reference Figures 8 to 10 , which is the third embodiment of the present invention, and is based on the previous embodiment.

[0065] Specifically, a cavity 3011 is provided on the inner wall of the movable block 301 and a connecting air pipe 3012 is provided on the end of the cavity 3011, a round ball 3013 is provided on the inner wall of the connecting air pipe 3012 and a second elastic member 3014 is provided on the outer wall of the round ball 3013, and an embolic column 3015 is also provided at the other end of the second elastic member 3014 for sealing the connecting air pipe 3012.

[0066] Among them, the cavity 3011 is connected to the connecting air pipe 3012, and is connected to the outside world through the connecting air pipe 3012. The round ball 3013 arranged inside the connecting air pipe 3012 blocks the connecting air pipe 3012 under the action of the second elastic member 3014 in the initial state, so that the air pressure inside the cavity 3011 is constant. When it is necessary to circulate with the outside air, the embolic column 3015 is opened outward and the round ball 3013 can be driven by the second elastic member 3014 to move backward to open the channel of the connecting air pipe 3012. It should be noted that here the embolic column 3015, the second elastic member 3014 and the round ball 3013 are a whole, and move together as a whole.

[0067] Preferably, a first sleeve 302 is provided on the outer wall of the moving block 301 and a first sealing ring 3021 and a second sealing ring 3022 are fixed on the inner wall of the first sleeve 302, and an air hole 3023 is also provided on the end face of the second sealing ring 3022 for air flow, a push column 3024 is provided on the end of the first sleeve 302 and the axis of the push column 3024 extends to the inner wall of the first sealing ring 3021 and pushes the push ring 3025 provided inside the first sleeve 302 to move, a connecting rod 3026 is provided at the axis of the push ring 3025 and the end of the connecting rod 3026 passes through the second sealing ring 3022 and is provided with a limiting ring 3027, and the limiting ring 3027 is located on the outer wall of the second sleeve 303 fixed at the other end of the moving block 301 and conflicts with the third elastic member 3031 on its inner wall.

[0068] The first sleeve 302 and the second sleeve 303 are respectively fixed on both sides of the moving block 301 and the interiors thereof are connected to the cavity 3011. 连通 , and at the same time has good sealing performance, isolating external air from entering the interior of the cavity 3011 through the first sleeve 302 and the second sleeve 303.

[0069] Depend on Figure 7 As can be seen, a first sealing ring 3021 and two second sealing rings 3022 are provided inside the first sleeve 302. The first sealing ring 3021 is used to seal the push pin 3024 to prevent leakage of the first sleeve 302 when the push pin 3024 pushes the push ring 3025. At the same time, when the push ring 3025 is pushed axially by the push pin 3024, it will be pressed against the surface of the second sealing ring 3022. At this time, the air inside the first sleeve 302 is discharged to the outside through the connecting air pipe 3012. When the air needs to be discharged to the outside, the ball 3013 is first driven backward by the embolization pin 3015 to open the connecting air pipe 3012, and then the embolization pin 3015 is closed. When the connecting air pipe 3012 is closed, the air inside the cavity 3011 is less and is in a negative pressure state. The push ring 3025 is pressed against the surface of the second sealing ring 3022 and cannot be reset. At this time, the limit ring 3027 squeezes the third elastic member 3031, causing it to deform and shrink.

[0070] Preferably, the outer wall of the connecting rod 3026 is provided with a connecting shell 304 and the outer wall of the connecting shell 304 is provided with a cylinder 3041, the cylinder 3041 is in contact with the pushing ring 305 provided on the inner wall of the moving block 301, and the outer wall of the pushing ring 305 is provided with a movable block 3051 and the movable block 3051 is pushed by the pushing ring 305 and clamped with the mounting guide rail 103 for fixation.

[0071] Among them, the connecting shell 304 is mounted on the outside of the connecting rod 3026 and moves inside the cavity 3011 together with the connecting rod 3026. When the connecting shell 304 moves toward the direction of the third elastic member 3031, the cylinder 3041 on the surface of the connecting shell 304 moves together. At this time, the moving block 301 can move freely outside the mounting guide rail 103.

[0072] When the movable block 301 needs to be fixed, the connecting air pipe 3012 is opened. At this time, the embolic column 3015 is opened to provide an air channel between the ball 3013 and the connecting air pipe 3012. The outside air enters between the push ring 3025 and the second sealing ring 3022 through the air hole 3023. At the same time, the push ring 3025 moves backward and drives the push column 3024 to move backward and reset. At this time, the third elastic member 3031 recovers its deformation and pushes the connecting shell 304 to move toward the direction of the second sealing ring 3022. During the movement of the connecting shell 304, the cylinder 3041 on the surface contacts the surface of the pushing ring 305 It should be noted that the contact surface between the pushing ring 305 and the cylinder 3041 is an inclined surface. The more the cylinder 3041 moves toward the second sealing ring 3022, the more it will squeeze the pushing ring 305 to move it outward, and the pushing ring 305 pushes the external movable block 3051 to be stuck in the groove of the mounting guide rail 103. At this time, the connecting air pipe 3012 is sealed and closed by the embolic column 3015, and the air pressure inside the cavity 3011 is constant, so that the movable block 301 is fixed to the outside of the mounting guide rail 103 without being affected by external forces, thereby fixing the mounting base 201.
