[0036] Some embodiments will be described below in conjunction with the drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

[0037] As a key component of new energy vehicle charging, the performance and quality of the charging gun are directly related to the charging efficiency and safety. Therefore, strict plug-in testing of the charging gun becomes an important link to ensure the reliability and safety of the charging equipment. In the related art, the charging gun testing device has poor height adaptability and cannot adapt to charging piles of various heights, which not only limits the range and accuracy of the test, but also may cause unnecessary damage to the charging gun or the charging pile due to the mismatch of the height during the test.

[0038] Therefore, the application provides a charging gun testing jig which can adapt to charging piles of different heights, protect the charging gun and the charging pile, thereby ensuring test safety and improving test efficiency.

[0039] Please refer to Figure 1 andFigure 2 In an embodiment of the present application, a charging gun test fixture 10 is provided. The charging gun test fixture 10 comprises a base 11, a clamping assembly 12, a translation assembly 13 and a lifting assembly 14. The base 11 is configured to support a charging pile (not shown in the figure). The clamping assembly 12 is configured to clamp a charging gun (not shown in the figure), and the charging gun is configured to be plugged into or pulled out of the charging pile for testing. The translation assembly 13 and the clamping assembly 12 are arranged on the same side of the base 11. The translation assembly 13 is configured to drive the clamping assembly 12 to move in a first direction to approach or move away from the charging pile. The lifting assembly 14 is arranged adjacent to the clamping assembly 12. The lifting assembly 14 is configured to drive the clamping assembly 12 to move in a second direction to adjust the height of the clamping assembly 12 relative to the base 11, and the second direction is perpendicular to the first direction.

[0040] In an embodiment of the present application, on the one hand, the translation assembly 13 is arranged to drive the clamping assembly 12 to move in the first direction to approach or move away from the charging pile, so as to realize the plugging and pulling out of the charging gun and the charging pile. On the other hand, the lifting assembly 14 is arranged to drive the clamping assembly 12 to move in the second direction to adjust the height of the clamping assembly 12 relative to the base 11. Since the base 11 is configured to support the charging pile, the height of the clamping assembly 12 relative to the charging pile can be adjusted. Thus, the charging gun test fixture 10 provided by the embodiment of the present application can control the horizontal distance and the vertical distance between the charging gun and the charging pile, so that the charging gun test fixture 10 can easily cope with charging piles of different heights. Whether the charging gun is installed at a low position or arranged at a high position, precise plugging and pulling out operations can be realized through the translation assembly 13 and the lifting assembly 14, thereby greatly enhancing the applicability and flexibility of the charging gun test fixture 10.

[0041] Please refer again to Figure 1 In some embodiments, the charging gun test fixture 10 comprises a first guide rod 15 and a second guide rod 16. The translation assembly 13 is connected to the clamping assembly 12 through the first guide rod 15, and the lifting assembly 14 is connected to the clamping assembly 12 through the second guide rod 16. The first guide rod 15 and the second guide rod 16 are both telescopic guide rods. In this way, by arranging the first guide rod 15 and the second guide rod 16, the connection of the translation assembly 13 and the lifting assembly 14 to the clamping assembly 12 can be realized, so that the translation assembly 13 and the lifting assembly 14 can drive the clamping assembly 12 to move, respectively. Understandably, in other embodiments, other telescopic connection structures, such as gears, can also be used to drive, and the present application does not limit this.

[0042] For example, the second guide rod 16 comprises a first end connected to the clamping assembly 12 and a second end connected to the lifting assembly 14. In some embodiments, the second guide rod 16 comprises an inner rod 161 and an outer rod 162 connected to each other. The first end of the inner rod 161 is connected to the clamping assembly 12, the second end of the inner rod 161 is connected to the first end of the outer rod 162, and the second end of the outer rod 162 is connected to the lifting assembly 14. In some embodiments, the second end of the inner rod 161 is at least partially accommodated in the outer rod 162, and the inner rod 161 is configured to slide in the outer rod 162. In this way, the relative sliding between the inner rod 161 and the outer rod 162 can adjust the distance between the clamping assembly 12 and the lifting assembly 14 caused by the movement of the clamping assembly 12 driven by the translation assembly 13.

[0043] In some embodiments, the first guide rod 15 and the second guide rod 16 have substantially the same structure, and the structure and working principle of the first guide rod 15 will not be described here. Similarly, the relative sliding of the first guide rod 15 can adjust the distance between the clamping assembly 12 and the translation assembly 13 caused by the movement of the clamping assembly 12 driven by the lifting assembly 14. Therefore, by providing the first guide rod 15 and the second guide rod 16, the clamping assembly 12 can be flexibly moved in the first direction and the second direction.

[0044] It can be understood that the number of the first guide rod 15 between the clamping assembly 12 and the translation assembly 13 and the number of the second guide rod 16 between the clamping assembly 12 and the lifting assembly 14 are not limited in the present application. For example, in an embodiment, two or more second guide rods 16 can be provided to enhance the stability of the movement of the clamping assembly 12 driven by the lifting assembly 14.

[0045] Please refer to Figure 2 and Figure 3 In some embodiments, a side surface of the base 11 is provided with a receiving groove 111. The translation assembly 13 comprises a first transmission rod 131, a first sliding block 132, and a first motor 133. The first transmission rod 131 is arranged in the receiving groove 111, and the first transmission rod 131 is connected to the first sliding block 132. The first sliding block 132 is connected to the clamping assembly 12 through the first guide rod 15. The first motor 133 is arranged at one end of the base 11, and the first motor 133 is located in the extension direction of the first transmission rod 131. The output shaft of the first motor 133 is connected to one end of the first transmission rod 131 to drive the first transmission rod 131.

[0046] For example, the first transmission rod 131 can be a screw rod, and the receiving groove 111 can be substantially square. In other embodiments, the receiving groove 111 can also be other shapes, and the present application does not limit the specific shape of the receiving groove 111, as long as the receiving groove 111 is sufficient to accommodate the first transmission rod 131. The first transmission rod 131 is rotatably installed in a first bearing (not shown in the figure) in the receiving groove 111. The first sliding block 132 is substantially square, and a first threaded hole 134 is formed in the lower end of the first sliding block 132. The first transmission rod 131 passes through the first threaded hole 134 to achieve threaded connection between the first transmission rod 131 and the first sliding block 132, and the first sliding block 132 is arranged on the outer side of the first transmission rod 131, i.e., close to the clamping assembly 12. The length of the first sliding block 132 is less than the width of the receiving groove 111, so that the first sliding block 132 can be partially accommodated in the receiving groove 111. The side of the first sliding block 132 away from the first transmission rod 131 is connected with the clamping assembly 12 through the first guide rod 15. Understandably, when the first motor 133 drives the first transmission rod 131 to rotate, the first transmission rod 131 drives the first sliding block 132 to move along the first transmission rod 131. In this way, the first transmission rod 131 can also provide the first sliding block 132 with guidance in the first direction (i.e., the horizontal direction).

[0047] In some embodiments, the charging gun test fixture 10 further comprises a bearing platform 17. The bearing platform 17 is arranged on the surface of the base 11 on the side where the clamping assembly 12 and the translation assembly 13 are arranged. The bearing platform 17 is arranged in the extension direction of the first transmission rod 131 and adjacent to the first motor 133. The bearing platform 17 is used to position the charging pile. For example, the bearing platform 17 can be substantially square. And the bearing platform 17 covers part of the receiving groove 111. In some embodiments, a plurality of positioning members (not shown in the figure) are arranged on the bearing platform 17, so that the charging pile is stably arranged on the bearing platform 17. Understandably, since the bearing platform 17 is arranged in the extension direction of the first transmission rod 131, and the charging pile is positioned on the bearing platform 17, when the first motor 133 drives the first transmission rod 131 to rotate, the first transmission rod 131 drives the first sliding block 132 to move along the first transmission rod 131 to approach or move away from the charging pile.

[0048] Please refer to Figure 1 and Figure 4 In some embodiments, the charging gun test fixture 10 further comprises a mounting rack 18. The mounting rack 18 is arranged on the other end of the base 11, and the mounting rack 18 is arranged in the extension direction of the first transmission rod 131. The mounting rack 18 is used to arrange the lifting assembly 14. For example, the mounting rack 18 can be a square plate, and the mounting rack 18 is fixedly installed on the other end of the base 11 and perpendicular to the base 11.

[0049] The mounting rack 18 is provided with a receiving groove 181 on one side close to the base 11. The lifting assembly 14 comprises a second transmission rod 141, a second sliding block 142 and a second motor 143. The second transmission rod 141 is arranged in the receiving groove 181, and the second transmission rod 141 is connected with the second sliding block 142. The second sliding block 142 is connected with the clamping assembly 12 through the second guide rod 16. The second motor 143 is arranged at one end of the mounting rack 18 away from the base 11, and the second motor 143 is located in the extension direction of the second transmission rod 141. The output shaft of the second motor 143 is connected with one end of the second transmission rod 141 to drive the second transmission rod 141.

[0050] In an embodiment, the second transmission rod 141 can be a lead screw for example, and the receiving groove 181 can be substantially square. The receiving groove 181 is further provided with a second bearing 182 close to one end of the base 11. The second transmission rod 141 is rotatably arranged in the second bearing 182 in the receiving groove 181. Figure 5 The second sliding block 142 is substantially square, and a second threaded hole 144 is arranged in the middle of the second sliding block 142. The second transmission rod 141 passes through the second threaded hole 144 to realize the threaded connection between the second transmission rod 141 and the second sliding block 142, and the second sliding block 142 is arranged on the outer side of the second transmission rod 141, i.e. close to the base 11. Please refer to Figure 1 and Figure 4 The length of the second sliding block 142 is smaller than the length of the receiving groove 181, the width of the second sliding block 142 is smaller than the width of the receiving groove 181, and the height of the second sliding block 142 is smaller than the height of the receiving groove 181. In this way, the second sliding block 142 can be accommodated in the receiving groove 181, which is beneficial to reduce the occupied volume of the charging gun test fixture 10. The side of the second sliding block 142 exposed from the receiving groove 181 is connected with the clamping assembly 12 through the second guide rod 16. Understandably, when the second motor 143 drives the second transmission rod 141 to rotate, the second transmission rod 141 drives the second sliding block 142 to move along the second transmission rod 141. In this way, the second transmission rod 141 can also provide the second sliding block 142 with guidance in the second direction (i.e. the vertical direction).

[0051] Please refer to Figure 5 In some embodiments, the clamping assembly 12 comprises a clamping head 121 and a connecting block 122. The connecting block 122 is connected with the translation assembly 13 through the first guide rod 15 on one side close to the translation assembly 13, and the connecting block 122 is connected with the lifting assembly 14 through the second guide rod 16 on one side close to the lifting assembly 14, so as to ensure the stable connection between the lifting assembly 14 and the translation assembly 13. The clamping head 121 is arranged on one side of the connecting block 122 away from the lifting assembly 14. In this way, the clamping head 121 is connected through the connecting block 122.

[0052] The clamping head 121 is generally in the shape of a U. In some embodiments, the clamping head 121 can be driven by air pressure, so that the charging gun can be quickly and stably clamped or released by air pressure control. The inner wall of the clamping head 121 is provided with a buffer layer 123 for protecting the surface of the charging gun and reducing the probability of damage to the charging gun. In some embodiments, the buffer layer 123 may, for example, include at least one of a rubber pad, memory foam, silicone, or foam plastic, etc., which are elastic materials.

[0053] Understandably, in use, the charging gun test fixture 10 provided by the present application places the charging pile on the bearing platform 17 of the base 11, places the charging gun in the clamping head 121, and clamps the charging gun by air pressure control of the clamping head 121. Subsequently, the second motor 143 is started, the output shaft of the second motor 143 drives the second transmission rod 141 to rotate, the rotation of the second transmission rod 141 drives the second sliding block 142 to move up and down in the accommodating groove 181, and due to the connection of the inner rod 161 and the outer rod 162, the clamping head 121 and the charging gun also move up and down to a specified height. Then, the first motor 133 is started, the output shaft of the first motor 133 drives the first transmission rod 131 to rotate, the rotation of the first transmission rod 131 drives the first sliding block 132 to move in the accommodating groove 111, thereby driving the entire clamping head 121 and the charging gun to move to a specified position in the horizontal direction. Continue to operate the first motor 133 to achieve the plugging operation of the charging gun.

[0054] In summary, the charging gun test fixture 10 provided by the present application can accurately control the movement distance of the clamping head 121 and the charging gun in the vertical direction through the precise cooperation of the second transmission rod 141 and the second sliding block 142 in the lifting assembly 14. This design enables the charging gun test fixture 10 to easily cope with charging piles of different heights, whether the charging piles are installed at a low position or arranged at a high position, precise plugging and unplugging operations can be achieved by adjusting the lifting assembly 14, thereby greatly enhancing the applicability and flexibility of the charging gun test fixture 10. Through the rotary motion of the first motor 133 in the translation assembly 13, the first transmission rod 131 is stably rotated in the bearing inside the base 11, which makes the first sliding block 132 accurately move horizontally along the track of the accommodating groove 111, thereby driving the entire clamping head 121 and the charging gun to achieve precise alignment and insertion into the charging pile socket, or to complete the smooth unplugging operation from the socket.

[0055] Understandably, in some embodiments, corresponding sensors are also provided in the charging gun test fixture 10 to achieve more precise control. For example, a distance sensor is provided on the first sliding block 132, a distance sensor is provided on the second sliding block 142, or a pressure sensor is provided on the clamping head 121, etc., which are not limited by the present application.

[0056] Moreover, the above-described drawings are only schematic illustrations of the processes included in the method according to the exemplary embodiments of the present application, and are not intended for limiting purposes.

[0057] The utility model is not limited to the above specific implementation. The ordinary skilled in the art can easily understand that the test fixture of the utility model has many alternative solutions without departing from the principles and categories of the utility model. The protection scope of the utility model is subject to the content of the claims.
