DETAILED DESCRIPTION

[0037] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0038] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments. Example 1

[0040] Reference Figures 1 to 6 , which is the first embodiment of the present invention, and provides a vehicle-mounted charging pile test platform. The vehicle-mounted charging pile test platform includes a shell mechanism 1, a test mechanism 2, a dust-proof limiting mechanism 3 and a protective mechanism 4. The dust-proof limiting mechanism 3 can protect the gun head plug interface from dust, and can better center and limit the insertion into the interface during the insertion process. The protective mechanism 4, in cooperation with the dust-proof limiting mechanism 3, can protect the display screen 24 used for human-computer interaction before and after use, and the two gun heads need to be in the inserted state at the same time before the protection can be released.

[0041] Specifically, the shell mechanism 1 includes a box body 11, a box cover 12 is rotatably provided on the top of the box body 11, and the box cover 12 is rotatably connected to the box body 11 through a hinge. A pressure rod 13 is fixed to the inner wall of the box cover 12, and two pressure rods 13 are provided on the box cover 12. Through the setting of the pressure rod 13, after the box cover 12 is merged into the box body 11, the downward pressure will be used to close the first baffle 42 and the second baffle 43 rotating on the display screen 24. A roller 14 is rotatably provided at the bottom of the box body 11, and four rollers 14 are provided at the bottom of the box body 11 to facilitate movement when the device is not in use.

[0042] Specifically, the test mechanism 2 is installed in the box body 11, and includes a shell 21 fixed in the box body 11. The detection interface 22, the load interface 23 and the display screen 24 are respectively installed on the top of the shell body 21. The display screen 24 is located on one side of the detection interface 22 and the load interface 23. The test mechanism 2 can realize the test of the vehicle charging pile, which is the existing technology. The working principle of this part is all the existing technology. Those skilled in the art can clearly know it and will not be elaborated here. The detection interface 22 is used to connect to the charging gun on the charging pile, and the load interface 23 is used to connect to the gun head on the load. The display screen 24 is a touch screen to realize the human-computer interaction function.

[0043] Specifically, the dustproof limiting mechanism 3 is installed on the testing mechanism 2, and includes a driving member 31 fixed on the detection interface 22 and the load interface 23. A support plate 32 is installed on the driving member 31, and an inclined frame 33 is fixed on the top of the support plate 32. A plate 1 34 is rotated on the detection interface 22 and the load interface 23, and a limiting plate 35 is rotated at one end of the plate 1 34. A sealing gasket 36 is fixed at the bottom of the limiting plate 35 and is located inside the detection interface 22 and the load interface 23.

[0044] Two driving members 31, a support plate 32, an inclined frame 33, a limit plate 35 and a sealing gasket 36 are respectively provided on a detection interface 22 and a load interface 23. The two inclined frames 33 are respectively fixed on the top of the two support plates 32. Through the setting of the inclined frames 33, when the gun head is pressed down and placed on it, the inclined surface inside it is squeezed to separate the two inclined frames 33 and the support plate 32, thereby acting on the driving member 31, and with the cooperation of plate 1 34, the two limit plates 35 are rotated and separated, thereby separating the sealing gaskets 36 in the detection interface 22 and the load interface 23.

[0045] The reaction force of the driving member 31 acts on the support plate 32 and the inclined frame 33, exerting force on the gun head located therebetween, so that it can be better centered and inserted into the interface, and the unfolded limiting plate 35 can limit the vertical surfaces on both sides of the gun head, so that the gun head can be inserted into the interface more accurately.

[0046] Through the setting of the sealing gasket 36, after the two limit plates 35 are rotated to cover the interface, they are located inside the interface to protect the detection interface 22 and the load interface 23 from dust. The support plate 32 and the inclined frame 33 are provided with an arc surface on one side. Through such a setting, after the gun head is pressed down to unfold it, the support plate 32 and the inclined frame 33 on both sides of the gun head can better contact and limit the gun head to achieve preliminary positioning.

[0047] Specifically, the protective mechanism 4 is installed on the test mechanism 2 and the driving member 31, including a transmission member 41 installed on the driving member 31 and the shell 21. Through the setting of the transmission member 41, when the driving member 31 is running, it can apply force to the first baffle 42 and the second baffle 43, giving it a rotational force. The first baffle 42 and the second baffle 43 are respectively installed on the transmission member 41. A rubber strip 44 is fixed on one side of the second baffle 43 and contacts one side of the first baffle 42. Through the setting of the rubber strip 44, it can be deformed and compressed. There is a certain space between the first baffle 42 and the second baffle 43 when rotating, closing and unfolding, and the opening and closing operation can be smoothly realized. An elastic member 45 is installed on the second baffle 43, and an arc groove 46 is opened on one side of the second baffle 43 and cooperates with the elastic member 45.

[0048] A rubber ring is fixed on the top of the shell 21 and is located on the periphery of the display screen 24. By setting the first baffle 42 and the second baffle 43, the display screen 24 is protected from dust when it is closed and in contact with the rubber ring, and it also plays a protective role to prevent the handheld gun head from accidentally falling and damaging the display screen 24 during the insertion process. The rubber ring plays a buffering and protective role when rotating and closing, and will not cause damage to the display screen 24.

[0049] Through the arrangement of the elastic member 45 and the arc groove 46, inserting any gun head into the detection interface 22 and the load interface 23 on both sides will not open the first baffle 42 and the second baffle 43. Only when both gun heads are fully inserted can the first baffle 42 and the second baffle 43 be unlocked and opened, thereby avoiding the situation where the gun head smashes the display screen 24, which is safer. In the process of removing the gun head, the corresponding first baffle 42 and the second baffle 43 will be closed, further improving the protection safety. Example 2

[0050] Reference Figures 2 to 9 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0051] Specifically, the driving member 31 includes a square rod 31-1 fixed on the detection interface 22 and the load interface 23, and a sliding sleeve 31-2 is provided on the surface of the square rod 31-1. A plate 2 31-3 is rotatable on the limit plate 35, and a rotating rod 1 31-4 is rotatable on the detection interface 22 and the load interface 23. The plate 2 31-3 is fixed to the surface of one end of the rotating rod 1 31-4, and the sliding sleeve 31-2 is slidably provided on the surface of the square rod 31-1. The rotating rod 1 31-4 is rotatably connected to the surface of the detection interface 22 and the load interface 23 through a bearing. The plate 2 31-3 is provided on the surface of the rotating rod 1 31-4. The plate 1 34 and the plate 2 31-3 are arranged parallel to each other and have the same length. The surface of the rotating rod 1 31-4 is provided with a sleeve 1 31-5. A connecting plate 31-6 is fixed between the surface of the sleeve 1 31-5 and the surface of the sliding sleeve 31-2. A fixed rod 31-12 is fixed between the surface of the limiting plate 35 and the surface of the sliding sleeve 31-2.

[0052] Through the arrangement of plate one 34 and plate two 31-3, when the rotating rod one 31-4 is rotated to rotate the plate two 31-3, and with the cooperation of plate one 34, the two sets of limit plates 35 can always be in a horizontal rotation and opened, and then the sealing gaskets 36 located in the interface at the bottom of the two limit plates 35 are taken out and separated, so that the gun head can be smoothly inserted into the interface, and the sliding sleeve 31-2 and the sleeve one 31-5 are indirectly connected through the connecting plate 31-6, so that when the sliding sleeve 31-2 moves, the sleeve one 31-5 can be driven to move, and through the arrangement of the fixing rod 31-12, the support plate 32 and the sliding sleeve 31-2 are indirectly connected, so that when the support plate 32 moves, the sliding sleeve 31-2 can be driven to move.

[0053] A guide groove 31-7 is provided on the surface of the rotating rod 31-4, and a guide column 31-8 is fixed to the inner wall of the sleeve 31-5, and slides in the guide groove 31-7. The guide groove 31-7 is divided into three parts. The first and third parts are for the guide column 31-8 to move with the sleeve 31-5 therein, without causing the rotating rod 31-4 to rotate. The second part is for the guide column 31-8 to move with the sleeve 31-5 therein, which can cause the rotating rod 31-4 to rotate.

[0054] During the process of inserting the gun head into the interface, the inclined frame 33 is squeezed to move it and the support plate 32, thereby driving the fixed rod 31-12 and the sliding sleeve 31-2 to move, so that the sleeve 1 31-5 and the guide column 1 31-8 move from the first part of the guide groove 1 31-7 through the second part to the third part, so that the rotating rod 1 31-4 rotates, and then the plate 2 31-3 rotates. With the cooperation of the plate 1 34, the two sets of limit plates 35 are rotated horizontally to open.

[0055] The surface of the square rod 31-1 is provided with a spring three 31-9, one end of which is fixedly connected to the surface of the sliding sleeve 31-2. Through the setting of the spring three 31-9, it is compressed when the sliding sleeve 31-2 moves, providing a force for its reset. At the same time, with the help of the sliding sleeve 31-2 and the fixed rod 31-12, the inclined frame 33 and the support plate 32 are acted on, applying force to the gun head so that it can be better centered and inserted into the interface.

[0056] A reinforcing block 1 31-10 is fixed at one end of the square rod 31-1, and is fixed to the top of the shell 21. The reinforcing block 1 31-10 reinforces and supports one end of the square rod 31-1 to prevent one end from being suspended in the air and being unstable. The rotating rod 1 31-4 is rotatably connected to the reinforcing block 2 31-11 through a bearing. The reinforcing block 2 31-11 is fixed at the top of the shell 21 and is rotatably connected to one end of the rotating rod 1 31-4. The end of the spring 31-9 away from the sleeve 31-2 is fixed to the surface of the reinforcing block 2 31-11. The rotating rod 1 31-4 is supported by the reinforcing block 2 31-11 to prevent one end from being suspended in the air, making it more stable when rotating.

[0057] The limiting plate 35 includes a square plate 35-1 that rotates on one end of plate one 34 and plate two 31-3, and a long plate 35-2 is fixed to one side of the square plate 35-1, and the long plate 35-2 on one side of the square plate 35-1 slides on the square plate 35-1 on the other side. The square plate 35-1 and the long plate 35-2 are designed as an integrated whole and combined into a complete limiting plate 35. The two square plates 35-1 are provided with square holes corresponding to the corresponding long plates 35-2, and the long plates 35-2 are slidably connected therein. Through such an arrangement, after the two limiting plates 35 are unfolded, the long plate 35-2 on one limiting plate 35 is still located in the square hole on the other limiting plate 35, and can still maintain its function, thereby improving the corresponding stability and strength, and the two long plates 35-2 can limit the vertical surfaces on both sides of the gun head, so that the gun head can be more accurately inserted into the interface. Example 3

[0058] Reference Figures 2 to 12 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0059] Specifically, the transmission member 41 includes a short block 1 41-1 fixed to the top of the shell 21, a short block 2 41-2 is fixed to the top of the shell 21, a rotating rod 2 41-3 rotates between the short block 1 41-1 and the short block 2 41-2, and the rotating rod 2 41-3 is rotatably connected to the short block 1 41-1 and the short block 2 41-2 through bearings respectively, and the first baffle 42 and the second baffle 43 are respectively sleeved on the surfaces of the two rotating rods 2 41-3, and a torsion spring 41-4 is fixed on the first baffle 42 and the second baffle 43, and the torsion spring 41-4 is sleeved on the surface of the rotating rod 2 41-3, and one end thereof is fixed to the surface of the rotating rod 2 41-3.

[0060] Through the setting of the torsion spring 41-4, the rotating rod 41-3 is deformed when it rotates, and with the cooperation of the elastic member 45 and the arc groove 46, when a gun head is inserted to deform the torsion spring 41-4 on one side of the rotating rod 31-4, a force is given to the first baffle 42 or the second baffle 43 to rotate. At this time, the action of the elastic member 45 and the arc groove 46 on the first baffle 42 and the second baffle 43 cannot be overcome, and the first baffle 42 and the second baffle 43 cannot be opened. Only when two gun heads are inserted and acted on at the same time can the action of the elastic member 45 and the arc groove 46 on the first baffle 42 and the second baffle 43 be overcome, and opening can be achieved with high safety.

[0061] A sleeve 41-5 is sleeved on one end surface of the rotating rod 41-3, and a guide groove 41-6 is opened on the surface of the rotating rod 41-3. A guide column 41-7 is fixed to the inner wall of the sleeve 41-5, and slides in the guide groove 41-6. The sleeve 41-5 is slidably sleeved on the surface of the rotating rod 41-3. The guide groove 41-6 is divided into three parts. The first and third parts are for the guide column 41-7 to move with the sleeve 41-5 therein, without causing the rotating rod 41-3 to rotate. The second part is for the guide column 41-7 to move with the sleeve 41-5 therein, which can cause the rotating rod 41-3 to rotate.

[0062] A fixing plate 41-8 is fixed between the surface of the sliding sleeve 31-2 and the surface of the second sleeve 41-5, and the sliding sleeve 31-2 and the second sleeve 41-5 are indirectly connected through the fixing plate 41-8. When the sliding sleeve 31-2 moves and drives the fixing plate 41-8 to move the second sleeve 41-5 on the second rotating rod 41-3, the second guide column 41-7 passes through the first part of the second guide groove 41-6 and enters the third part, thereby causing the second rotating rod 41-3 to rotate and causing the torsion spring 41-4 to undergo torsional deformation.

[0063] The elastic member 45 includes a groove 45-1 formed in the second baffle 43, and a cylinder 45-2 slides on the inner wall of the groove 45-1. A ball 45-3 is embedded in one end of the cylinder 45-2 and extends to the inner wall of the arc-shaped groove 46. The ball 45-3 is rotatably connected to the cylinder 45-2. A spring piece 45-4 is fixed between the inner wall of the groove 45-1 and the surface of the cylinder 45-2. A positioning groove 45-5 is formed on the inner wall of the groove 45-1, and a positioning block 45-6 is fixed on the surface of the cylinder 45-2 and slides in the positioning groove 45-5.

[0064] By setting the spring piece 45-4, elastic force is provided for placing the ball 45-3 on the cylinder 45-2 in the arc groove 46, acting between them so that the second baffle 43 acts on the first baffle 42, and the two baffles will not be easily opened. When any gun head is inserted to deform the torsion spring 41-4 on one side, the ball 45-3 cannot be separated from the arc groove 46, and the first baffle 42 and the second baffle 43 will not be opened. Only when both gun heads are inserted and the torsion springs 41-4 on both sides are deformed, can the first baffle 42 and the second baffle 43 be opened.

[0065] A guide rod 37 is fixed on both the detection interface 22 and the load interface 23, and the support plate 32 is sleeved on their surfaces.

Two guide rods 37 are provided on one detection interface 22 and the load interface 23, and the support plate 32 is slidably sleeved on its surface. The support plate 32 is guided and limited by the guide rod 37, and the corresponding structure is shielded and protected by the setting of the cover 38. Example 4

[0066] Reference Figures 2 to 18 , which is the fourth embodiment of the present invention, and is based on the first three embodiments.

[0067] Specifically, the testing mechanism 2 also includes a controller 25, a control guide resistor 26, an electric energy metering module 27, a built-in oscilloscope module 28, a power module 211, a memory 214 and a positioning module 215 arranged in the shell 21, and the shell 21 is provided with a pulse input / output interface 29, a communication interface 210, a temperature sensor 212 and a humidity sensor 213.

[0068] The control guide resistor 26 is electrically connected to the detection interface 22 and the power metering module 27 respectively, the controller 25 is electrically connected to the display screen 24, the power module 211, the temperature sensor 212, the humidity sensor 213, the memory 214, the positioning module 215, the communication interface 210 and the pulse input / output interface 29 respectively, the built-in oscilloscope module 28 is electrically connected to the controller 25, the power metering module 27 and the load interface 23 respectively, the detection interface 22 is electrically connected to the charging pile, the load interface 23 is electrically connected to the load, and the communication interface 210 is electrically connected to the host computer. This is the existing technology, and the working principles of this part are all existing technology. Those skilled in the art can clearly understand it and will not be elaborated here.

[0069] A movable plate 15 is rotatable on the box cover 12, and a movable block 16 is slid on the box body 11. One end of the movable plate 15 is rotatably connected to the top of the movable block 16. A box buckle 17 is provided between the box body 11 and the box cover 12, and a handle 18 is fixed to the outer surface of the box body 11. Through the arrangement of the movable block 16 and the movable plate 15, the box cover 12 can be limited after opening so that it will not be opened and closed excessively. The box buckle 17 is used to facilitate the connection between the closed box cover 12 and the box body 11 to prevent it from being opened at will.

[0070] A stabilizing mechanism 5 is mounted on the box 11 and the housing 21 and includes a horizontal plate 51 fixed to the top of the housing 21. A trigger plate 52 slides inside the horizontal plate 51. One end of the trigger plate 52 extends into the detection interface 22 and the load interface 23, and the other end extends into the box 11. A vertical plate 53 slides inside the box 11. The vertical plate 53 has a slot 54 formed therein and engages with one end of the trigger plate 52. An arc-shaped plate 55 is fixed to the lower end of the vertical plate 53, and a rubber pad 56 is fixed to the bottom of the arc-shaped plate 55.

[0071] Through the setting of the stabilizing mechanism 5, when the box cover 12 is opened, it is acted on with the help of the movable block 16 to achieve preliminary fixation of the roller 14, and then it is fixed again after the gun head is inserted. Both ends of the trigger plate 52 are provided with inclined surfaces, and the inclined surface at one end located in the detection interface 22 and the load interface 23 squeezes the gun head when it is inserted into the interface, thereby causing it to move.

[0072] The upper end of the vertical plate 53 and one side of the movable block 16 are both provided with inclined surfaces. When the box cover 12 is opened, the movable block 16 is driven to move by the movable plate 15, thereby contacting and squeezing the vertical plate 53 downward, so that the vertical plate 53 drives the arc plate 55 and the rubber pad 56 thereon to move downward, so that the rubber pad 56 contacts the roller 14 to achieve preliminary fixation.

[0073] An inclined surface is provided in the slot hole 54. After the trigger plate 52 moves down a short distance with the vertical plate 53, there is still a certain space between the upper surface of the trigger plate 52 and the slot hole 54. After the trigger plate 52 moves and the inclined surface on it contacts the inclined surface in the slot hole 54, it squeezes the vertical plate 53 and the curved plate 55 to continue to move downward, compressing the rubber pad 56, increasing the effect with the roller 14, and playing a secondary fixing role to prevent the device from moving during use.

[0074] A slide groove 57 is provided in the horizontal plate 51, and a slider 58 is fixed to the bottom of the trigger plate 52, and it slides in the slide groove 57. A spring 1 59 is fixed between the surface of the slider 58 and the inner wall of the slide groove 57. A limiting groove 510 is provided in the box body 11, and a limiting block 511 is fixed on one side of the vertical plate 53, and it slides in the limiting groove 510. A spring 2 512 is fixed between the surface of the limiting block 511 and the inner wall of the limiting groove 510.

[0075] The trigger plate 52 is guided and limited by the sliding groove 57 and the slider 58. The spring 1 59 is set to compress after the trigger plate 52 and the slider 58 move, providing a force for the reset of the trigger plate 52 and the slider 58. The vertical plate 53 is guided and limited by the limiting groove 510 and the limiting block 511. The spring 2 512 is set to compress after the vertical plate 53 and the limiting block 511 move, providing a force for the reset of the vertical plate 53 and the limiting block 511.

[0076] When in use, the gun head is pressed down and placed on the inclined frame 33, the inclined surface inside it is squeezed, so that the two inclined frames 33 and the support plate 32 are separated, and then the driving member 31 is acted on, and with the cooperation of plate 1 34, the two limit plates 35 are rotated and separated, thereby separating the sealing gaskets 36 in the detection interface 22 and the load interface 23, and the reaction force of the driving member 31 acts on the support plate 32 and the inclined frame 33, applying force to the gun head located therebetween, so that it can be better inserted into the interface in the center, and the unfolded limit plates 35 can limit the vertical surfaces on both sides of the gun head, so that the gun head can be more accurately inserted into the interface.

[0077] The driving member 31 acts on the transmission member 41, causing the rotating rod 2 41-3 thereon to rotate and the torsion spring 41-4 to torsionally deform. With the cooperation of the elastic member 45 and the arc groove 46, when a gun head is inserted to deform the torsion spring 41-4 on one side of the rotating rod 1 31-4, a force with a rotational tendency is given to the first baffle 42 or the second baffle 43. At this time, the action of the elastic member 45 and the arc groove 46 on the first baffle 42 and the second baffle 43 cannot be overcome, and the first baffle 42 and the second baffle 43 cannot be opened. Only when the two gun heads are inserted and acted on at the same time can the action of the elastic member 45 and the arc groove 46 on the first baffle 42 and the second baffle 43 be overcome, and the opening is achieved with high safety, and then the corresponding test is carried out through the testing mechanism 2.

[0078] In summary, the dustproof limiting mechanism 3 can be used to protect the gun head plug interface from dust. Compared with the existing technology, it can be better centered and limited when inserted into the interface during the insertion process. The protective mechanism 4 cooperates with the dustproof limiting mechanism 3 to protect the display screen 24 used for human-computer interaction before and after use. Compared with the existing technology, the two gun heads need to be in the inserted state at the same time before the protection can be released, which has high safety.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
