Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, specifically to a leak-proof detection device for welding nuts on automotive charging socket brackets. Background Technology
[0002] With the increasing severity of the energy crisis and environmental pollution, energy-saving and new energy vehicles are becoming a hot research topic. As a type of energy-saving and new energy vehicle, pure electric vehicles have many advantages during operation, including zero emissions, high energy efficiency, low noise, and recyclable energy. Therefore, vigorously developing pure electric vehicles is of great significance to energy security and environmental protection. Currently, there are two charging methods for pure electric vehicles: slow charging and fast charging. Generally, a charging socket is required to charge pure electric vehicles.
[0003] The car charging socket bracket has several mounting holes. Depending on the installation requirements, some mounting holes are welded with nuts. However, the mounting holes at the four ends of the charging socket bracket are not welded with nuts. During the manufacturing process of the charging socket bracket, it is common for corresponding holes to be without nuts, or for nuts to be welded to holes that do not require them. Since there are a large number of nuts welded on the charging socket bracket, it is easy to make mistakes if you only observe whether there are mis-welded or missing welds by visual inspection. Therefore, this utility model provides a car charging socket bracket nut welding leak prevention detection device, which can detect the missing and mis-welded nuts on the charging socket bracket. Utility Model Content
[0004] In order to overcome the above-mentioned defects in the prior art, this utility model provides a leak-proof detection device for welding nuts of car charging socket brackets.
[0005] A leak-proof detection device for welding nuts on a car charging socket bracket includes a detection plate with a sensor installed on it. The sensor's installation position corresponds to the welding nut on the charging socket bracket. The detection plate is inclined and mounted on a fixed bracket. A positioning post is installed on the fixed bracket, and the positioning post corresponds to the mounting holes at the four ends of the charging socket bracket. The bottom of the positioning post has a supporting protrusion, and the charging socket bracket is located on the supporting protrusion.
[0006] Furthermore, the fixed bracket is provided with a support plate, the top of which is connected to the movable plate via a telescopic spring. A sensor is installed on the movable plate to detect the welded nuts on the side plate of the charging socket bracket. The movable plate is slidably connected to the support plate via a guide rod.
[0007] Furthermore, a control box is provided on the fixed bracket, and an audible and visual alarm is provided on the control box.
[0008] Furthermore, the sensor is provided with threads, and the sensor is mounted on the detection plate and the moving plate by fastening nuts.
[0009] Due to the adoption of the above technical solutions, the beneficial technical effects of this utility model are as follows: When using this utility model to detect mis-welding and missing welding of the welding nuts on the charging socket bracket, if the welding nuts are mis-welded on the mounting holes at the four ends, the charging socket bracket cannot be inserted into the positioning post, indicating that the welding nuts are mis-welded. After the charging socket bracket is inserted into the positioning post, the welding nuts are detected by the sensor, and the sensor transmits a signal indicating whether there is a missing welding of the welding nuts, thereby realizing the detection of missing welding of the welding nuts, which is convenient.

[0015] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0016] according to Figure 1-4As shown, a leak-proof detection device for welding nuts on a car charging socket bracket includes a detection plate 1. A sensor 2 is provided on the detection plate 1. The installation position of the sensor 2 corresponds to the welding nut 4 on the charging socket bracket 3. The detection plate 1 is inclined and is mounted on a fixed bracket 5. A positioning post 6 is installed on the fixed bracket 5. The positioning post 6 corresponds to the mounting holes 7 at the four ends of the charging socket bracket 3. A supporting protrusion 8 is provided at the bottom of the positioning post 6, and the charging socket bracket 3 is located on the supporting protrusion 8.
[0017] In the above specific technical solution, the positioning column 6 positions the charging socket bracket 3 by passing through the mounting holes 7 at the four ends of the charging socket bracket 3, and the supporting protrusion 8 supports the charging socket bracket 3 so that the welding nut 4 on the charging socket bracket 3 placed on the supporting protrusion 8 just contacts the sensor 2 on the detection plate 1, thereby detecting the welding nut 4 on the charging socket bracket 3.
[0018] When using this utility model to detect mis-welding and missing welding of the welding nut 4 on the charging socket bracket 3, if the welding nut 4 is mis-welded on the mounting holes 7 at the four ends, the charging socket bracket 3 cannot be inserted into the positioning post 6, indicating that the welding nut 4 has a mis-welding. After the charging socket bracket 3 is inserted into the positioning post 6, the welding nut 4 is detected by the sensor 2, and the sensor 2 transmits a signal indicating whether the welding nut 4 has a missing weld, thereby realizing the detection of missing weld of the welding nut 4, which is convenient.
[0019] The fixed bracket 5 is provided with a support plate 9. The top of the support plate 9 is connected to the movable plate 11 by a telescopic spring 10. A sensor 2 is installed on the movable plate 11. The sensor 2 on the movable plate 11 is used to detect the welded nut 4 on the side plate of the charging socket bracket 3. The movable plate 11 is slidably connected to the support plate 9 by a guide rod 12.
[0020] Welded nuts 4 are also provided on the side plate of the charging socket bracket 3. They are detected by the sensor 2 on the moving plate 11. When the charging socket bracket 3 moves from top to bottom along the positioning column 6, it comes into contact with the welded nuts 4 and the sensor 2, thereby detecting the welded nuts 4 on the side plate of the charging socket bracket 3 by the sensor 2.
[0021] The fixed bracket 5 is equipped with a control box 13, and the control box 13 is equipped with an audible and visual alarm 14. When all the sensors 2 detect that the welding nut 4 is welded, they will transmit the correct signal, and the audible and visual alarm 14 on the control box 13 will light up and emit a sound. If the sensors 2 detect that the welding nut 4 is incorrectly welded, the audible and visual alarm 14 on the control box 13 will not react.
[0022] The sensor 2 is threaded and is mounted on the detection plate 1 and the moving plate 11 by a fastening nut 15. The sensor 2 is easy to install and convenient to repair and replace.
[0023] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
