Description

Technical Field

[0001] The present invention relates to the technical field of new energy automobile manufacturing, and more specifically, to an electric hatch cover with an auxiliary spring and a manufacturing device thereof. Background Art

[0002] At the charging port of new energy vehicles, the electric cover is a cover that is opened and closed by electric drive. It is usually on the side or front of the car body. When the new energy vehicle needs to be charged, the cover will automatically open by operating the button in the car, the remote control key or the mobile phone APP, exposing the charging port for easy insertion of the charging gun. After charging is completed, the cover can be automatically closed by operating again to protect the charging port from external environmental influences such as dust, rain, etc.

[0003] A sealing strip is usually arranged between the cover and the vehicle body to seal and isolate water vapor and dust. However, as time goes by and the number of uses increases, the sealing strip between the cover and the vehicle body may deform to a certain extent, resulting in gaps. As a result, in some harsh environments, such as rainy days and dusty days, water stains and dust can easily penetrate into the cover through the gaps at the deformed parts of the sealing strip, which can easily cause damage to the charging port.

[0004] When welding the springs inside the mouth cover with existing welding equipment, it is usually done manually. When there are a large number of springs, the efficiency of manual welding is low. In addition, due to the special shape of the springs, the springs are not easy to fix during manual welding, and the springs are easily welded crooked, affecting the use of the mouth cover.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention designs the mouth cover body as a double-layer structure of an outer cover and an inner cover, and connects the outer cover and the inner cover through eight springs, so that when the mouth cover body is closed, the outer cover and the first rubber strip are pressed and fitted, and the inner cover and the second rubber strip are pressed and fitted to form a double-layer sealing structure, thereby enhancing the sealing performance of the mouth cover body, and the eight springs generate elastic force on the inner cover, so that the inner cover and the second rubber strip are more closely fitted. Even if the second rubber strip is deformed to a certain extent after long-term use, the eight springs provide continuous pressure on the inner cover to compensate for the deformation, maintain the stability of the sealing performance, and help prevent water stains and dust from entering the charging port, thereby protecting the safety of the charging interface and internal circuits.

[0021] 2. The present invention is designed to facilitate the positioning and fixing of eight springs by designing a welding device. The inner cover is placed on a flip welding table, the inner cover is clamped and fixed by a clamping assembly on the flip welding table, and the eight springs are positioned by a positioning assembly above the flip welding table so that the eight springs fit on the inner cover, and then welding is performed by a welding machine body. After the welding of the inner cover and the eight springs is completed, the flip welding table is flipped, the lifting welding table is raised, and the lifting welding table raises the outer cover to a state where it fits with the bottom of the eight springs, and then welding is performed by a welding machine body to complete the welding of the outer cover and the eight springs. By designing a clamping assembly and a positioning assembly, the accuracy and convenience of welding are guaranteed, the working efficiency of welding is improved, and the problems that the springs are not easy to fix during manual welding, and the springs are easily welded crookedly, which affects the use of the mouth cover, and the number of springs is large and the working efficiency is low during manual welding are solved.

[0022] 3. The present invention also makes the design of the clamping groove block of the clamping assembly match the shape of the groove of the inner cover, and drives the rotating rod 2 to rotate by rotating the motor, so that the clamping frame 1 and the clamping frame 2 move towards each other on the rotating rod 2, and the clamping groove block is clamped on the groove of the inner cover to clamp and fix the inner cover, which not only ensures the stability of the welding process, but also ensures that when the flip welding table is flipped, the inner cover follows the flipping operation and remains fixed in the support table.

[0023] 4. The present invention also works through telescopic motor 2 to push rack 2 to move forward on support frame 2, drive gear 2 to rotate, gear 2 drives coaxially connected gear 3 to rotate, gear 3 rotates and drives rack 3 meshing therewith to move vertically downward along the direction of the slide seat, so that the fixed column drives the positioning block to move downward, and the positioning block is pressed down on the top surface of the inner cover on the support table. At this time, by placing eight springs 1 in the spring placement holes respectively, and then pulling the rotating grip downward, the card block slides in the sliding groove, the rotating grip drives the lower pressing block to move downward, and the eight pressure heads of the lower pressing block are pressed down on the eight spring placement holes respectively. The top of the spring one inside is moved, and then the handle is rotated manually to make the block slide to the side of the bottom of the sliding groove. At this time, the block and the sliding groove form a clamping structure to prevent the elastic force of the spring two from causing the rotating handle to move up. At this time, the top of the spring one is subjected to the pressure of the pressing block, and the spring one produces a compression deformation, so that the bottom of the spring one is tightly attached to the top surface of the inner cover. Then, by controlling multiple welding heads one to move forward to the welding position of the spring one corresponding to each welding head one, and welding is performed, the stability and reliability of welding the top surface of the inner cover and the bottom of the spring one are guaranteed, and the problem of the spring being easily skewed during welding is further solved.
