[0025] Many specific details are set forth in the following description in order to provide 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 can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0026] Secondly, the term "an embodiment" or "embodiment" as used 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 different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.
[0027] Example 1
[0028] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention, which provides a testing device for a new energy vehicle charging interface. The testing device includes a support and detection mechanism 100, a plugging and unplugging mechanism 200, and a limit counting mechanism 300. The support and detection mechanism 100 can test the charging interface, the plugging and unplugging mechanism 200 can perform a number of plugging and unplugging operations, and the limit counting mechanism 300 can easily fix the charging interface being tested. It can be in a fixed state during plugging and unplugging and in an unlocked state when not plugging and unplugging, and can be easily removed after the test is completed.
[0029] Specifically, a platform 102 is fixedly connected to the top of the housing 101, a detection seat 103 is installed on the top of the platform 102, and a positioning column 104 is fixedly connected inside the detection seat 103.
[0030] The detection base 103 is used to detect whether the charging interface is energized and the current magnitude when it is inserted into the charging connector 203. The detection base 103 is existing technology, and the working principle of this part is also existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here. There are four positioning posts 104, which facilitate the lateral positioning of the charging interface placed in the detection base 103.
[0031] Specifically, a movable column 202 is slidably connected to the surface of the connecting plate 201, and a charging connector 203 is fixedly connected to the lower end of the movable column 202.
[0032] The movable column 202 passes through the connecting plate 201 and is slidably connected to it. The connecting plate 201 guides and limits the movable column 202, so that it can only move vertically. The charging connector 203 is connected to the power supply through a wire. The charging connector 203 can be repeatedly plugged in and unplugged by moving the charging connector 203 up and down.
[0033] Specifically, one end of the pressure plate 301 is fixedly connected to the surface of the movable column 202 and is located on one side of it. A limiting member 302 is installed on the top of the platform 102. A vertical rod 303 is fixedly connected to the top of the platform 102. A horizontal plate 304 is fixedly connected to the upper end of the vertical rod 303 and is sleeved on the surface of the pressure plate 301. A counter 305 is fixedly connected to the top of the horizontal plate 304 and is located on one side. A pressing member 306 is installed on the surface of the movable column 202.
[0034] The pressure plate 301 moves up and down with the movable column 202, which can act on the limiting member 302 to limit and fix the charging interface. The vertical rod 303 supports and fixes the horizontal plate 304, and the horizontal plate 304 guides and limits the pressure plate 301, making the pressure plate 301 more stable when moving up and down and reducing the possibility of deformation. The reciprocating up and down movement of the lower pressing member 306 acts on the counter 305, thereby realizing the feedback recording of the number of insertion and removal, and realizing the durability test.
[0035] Example 2
[0036] Reference Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0037] Specifically, the frame 105 is fixedly connected to the top of the platform 102 and located on one side thereon. The connecting plate 201 is fixedly connected to the surface of the frame 105. The controller 106 is fixedly connected to the top of the platform 102 and located at one corner thereon.
[0038] The connecting plate 201 is located on one side of the frame 105, supports the motor 206 through the frame 105, controls the operation of the motor 206 through the controller 106 and records the data transmitted by the counter 305.
[0039] A cover 107 is fixedly connected to the top of the platform 102 and is fitted onto the surface of the limiting member 302 and the pressure plate 301.
[0040] There are two covers 107, which are symmetrically distributed on the top of the platform 102. The covers 107 shield the limiting member 302 to prevent it from coming into contact with the human body and causing damage during operation.
[0041] The frame 204 is fixedly connected to the upper end of the movable column 202, and a short rod 205 is slidably connected to the inner wall of the frame 204.
[0042] A bearing is fitted on the surface of the short rod 205. The inner surface of the bearing inner ring is fixedly connected to the outer surface of the short rod 205, and the outer surface of the bearing outer ring is in contact with the inner surface of the square frame 204. The bearing reduces the resistance between the short rod 205 and the square frame 204 when the short rod 205 rotates, so that the short rod 205 can drive the square frame 204 and the movable column 202 to move up and down more smoothly when it rotates.
[0043] A motor 206 is fixedly connected to the top of the frame 105. The output shaft of the motor 206 is fixedly connected to a turntable 207. A short rod 205 is fixedly connected to the surface of the turntable 207 and is located on one side of it.
[0044] The rotation of the output shaft of motor 206 causes turntable 207 to rotate, which in turn drives short rod 205 to rotate, driving square frame 204 and movable column 202 to move up and down, thereby driving charging connector 203 to move up and down, thus realizing the durability test of plugging and unplugging the charging interface.
[0045] A fixed plate 302a is fixedly connected to the top of the platform 102. A square rod 302b is slidably connected to the surface of the fixed plate 302a. A movable plate 302c is fixedly connected to one end of the square rod 302b. A first roller 302d is rotatably connected to the surface of the movable plate 302c.
[0046] The movable plate 302c is guided and limited by the square rod 302b, so that the movable plate 302c moves along the axial direction of the square rod 302b. Two first rollers 302d are rotatably connected to the surface of one movable plate 302c through a rotating shaft. The four first rollers 302d move to the top four corners of the charging interface and limit its longitudinal movement. When the charging connector 203 is unplugged and moves upward, the first rollers 302d will gradually detach from the charging interface and lose their limit, thus fixing it during the plugging and unplugging process and making it easy to remove later.
[0047] A U-shaped plate 302e is fixedly connected to the end of the square rod 302b away from the moving plate 302c, and a second roller 302f is rotatably connected to the inner wall of the U-shaped plate 302e.
[0048] The downward movement of the pressure plate 301 gradually compresses the second roller 302f, causing it to move. This, in turn, moves the U-shaped plate 302e, the square rod 302b, the moving plate 302c, and the first roller 302d, thus fixing the charging interface. After the second roller 302f contacts the vertical surface of the pressure plate 301, it will not move again regardless of up or down movement. The second roller 302f reduces the resistance between the pressure plate 301 and the pressure plate 301, allowing the pressure plate 301 to better drive the second roller 302f when it moves up and down, thus moving the square rod 302b and the moving plate 302c.
[0049] A first spring 302g is sleeved on the surface of the square rod 302b. The two ends of the first spring 302g are fixedly connected to the surfaces of the fixed plate 302a and the U-shaped plate 302e, respectively. A guide rod 302h is slidably connected to the surface of the fixed plate 302a, and one end of the guide rod is fixedly connected to the surface of the connecting plate 201.
[0050] After being compressed by the movement of the U-shaped plate 302e, the first spring 302g provides power for the reset of the U-shaped plate 302e, the square rod 302b, the second roller 302f, the moving plate 302c, and the first roller 302d. The guide rod 302h guides and limits the connecting plate 201, while protecting the square rod 302b and sharing the force applied during the process of pulling out the charging connector 203 and driving the charging interface upward.
[0051] The short plate 306a is fixedly connected to the surface of the pressure plate 301. A slide rod 306b is slidably connected to the surface of the short plate 306a. A round block 306c is fixedly connected to the lower end of the slide rod 306b.
[0052] The slide bar 306b passes through the short plate 306a and is slidably connected to it. The slide bar 306b guides the circular block 306c. At the same time, when the circular block 306c contacts the counter 305, the short plate 306a can still move smoothly with the pressure plate 301.
[0053] A second spring 306d is fitted onto the surface of the slide bar 306b, and the two ends of the second spring 306d are fixedly connected to the bottom of the short plate 306a and the top of the round block 306c, respectively.
[0054] After the circular block 306c contacts the counter 305, as the short plate 306a moves down and is compressed by the second spring 306d, the movement of the short plate 306a and the pressure plate 301 is not affected, allowing the circular block 306c to better contact and apply pressure to the counter 305, thereby improving the accuracy of counting.
[0055] In use, the charging interface is placed on the detection seat 103, and the positioning pins 104 are inserted into the mounting holes at its four corners. The operation of the motor 206 is controlled to make the turntable 207 rotate, which in turn drives the short rod 205 to rotate, causing the square frame 204, the movable pin 202 and the charging connector 203 to move down first. The downward movement of the movable pin 202 drives the pressure plate 301 and the lower pressure piece 306 to move down. As the pressure plate 301 moves down, it squeezes the second roller 302f to move, which in turn drives the U-shaped plate 302e, the square rod 302b, the movable plate 302c and the first roller 302d to move, and the first spring 302g is compressed, moving the four first rollers 302d to the top four corners of the charging interface.
[0056] As the pressure plate 301 moves, the second roller 302f comes into contact with its vertical surface, and its downward movement no longer drives the first roller 302d to move. At this time, the charging connector 203 does not come into contact with the charging interface during its downward movement. When it continues to move downward, the charging connector 203 is inserted into the charging interface and detected by the detection seat 103. At the same time, the pressing member 306 acts on the counter 305 to make the counter 305 count.
[0057] As the turntable 207 and short rod 205 rotate, the square frame 204, movable column 202, charging connector 203, and pressure plate 301 move upward, realizing the unplugging operation. At the same time, under the action of the first spring 302g, the first roller 302d, movable plate 302c, square rod 302b, U-shaped plate 302e, and second roller 302f are reset. When the square frame 204 moves downward as the turntable 207 and short rod 205 rotate, the operation is repeated to realize the insertion and removal durability test. After the test is completed, the longitudinal limit is released to facilitate the removal of the charging interface.
[0058] In summary, with the cooperation of the limit counting mechanism 300 and the insertion / removal mechanism 200, the charging interface to be tested can be easily fixed. Compared with the prior art, the operation is simple, and it can be in a fixed state during insertion / removal and in an unlocked state when not inserted / removed, making it easy to remove after the test is completed.
[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
