Problems solved by technology

[0003] The hanging block in the push lock switch uses a slope and steps to jointly control the movement direction of the hanging column to realize the function of pressing the switch. Because of the steps, the hanging piece will be raised and bent every step of the way, and it is easy to be pulled apart under force. When the hanging point of the steps is locked, the matching surface is too small and has a slope, which is not conducive to the force
Another kind of anti-lock switch adopts a structure similar to a ballpoint pen. The width and thickness of the stress point do not exceed 1mm, and it cannot withstand a large strong pulling force. The charging port of a new energy vehicle generally has two charging stations, one for fast charging and one for slow charging. When the two charging bases are put together, the cover of the charging port is relatively large and heavy. In some cars, the double charging port is placed on the grille of the front of the car, and the vibration of the car body when driving on a bumpy road will be transmitted to the cover of the charging port. Give the cover a relatively strong pulling force (this pulling force is greater than 200N). The pressing switch on the market is under a strong pulling force of less than 180N. After being subjected to a large pulling force, the switch will be damaged and fail, which is not suitable for the needs of new energy vehicles.
[0004] In addition, after the cover is opened, the guides are easy to enter into the spring block and affect the movement of the spring block. Especially when the electric car needs to open the cover for a long time to charge, the switches are exposed to the outside and easy to enter foreign objects, causing sticking and affecting the pressing stop. Normal use of the lock switch
The charging port at the grille is suitable for a four-link structure to be used as a kinematic hinge, which is complex in structure, high in cost, and low in standardization

Embodiment 1

[0035] see Figure 1-13 , in an embodiment of the present invention, a closed type automobile exterior cover type large pull lock lock switch includes a bottom case 1 correspondingly installed on the charging port or the fuel port or the gas filling port and a cover 2 hinged on the bottom case 1 , the bottom shell 1 is provided with an opener 6 for locking or popping the cover 2 open, the opener includes a connection shell 601 fixed on the bottom shell 1, and a guide hanging shell that is telescopic inside the connection shell 601 603, the connecting shell 601 is provided with a hole c608, the inner wall of the hole c608 is rotatably connected with a rotating shaft 615, the inner side of the rotating shaft 615 is fixed with a swing block 614, and above the swing block 614 is provided with a shrapnel 611, so The two ends of the shrapnel 611 are respectively fixed with a first hanging post 612 and a second hanging post 613, the guide hanging shell 603 is sleeved in the connection ...

Embodiment 2

[0054] Such as Figure 14As shown, the difference from Embodiment 1 is that the guide groove includes a starting guide groove 6034, a hanging block groove 6031, a second step 6035, a locking and hanging platform 6033 and a first step 6032, wherein the second step 6035, the second step There is a height difference between the third step 6036 and the first step 6032 in turn. There is no step between the second step 6035 and the first step 6032. If no steps are made, the cylinder can be cut by the upper slope to unlock in the next sequence. The steel sheet will not deform when locking, and the hanging shell can be subjected to a greater pulling force than 50N, when the pulling force continues to increase, the hanging case will be pulled apart, the switch will not be damaged, and can continue to be used. damaged. When the strong pulling force is greater than 50N and less than 100N, the post is forcibly pulled apart from the locking step after deformation.

Embodiment 3

[0057] Such as Figure 15 As shown, the difference between this embodiment and Embodiment 1 is that the guide groove includes a starting guide groove 6034, a hanging block groove 6031, a second step 6035, a locking and hanging platform 6033, a third step 6036 and a first step 6032, wherein there is a height difference between the second step 6035, the third step 6036 and the first step 6032, and the cover plate 605 is provided with a second limiting step 6052 on the side close to the guide hanging shell 603. When in use, during the unlocking and locking process of the switch, the stroke of the charging port and fuel port should not be greater than 3mm. When the hanging shell is pressed down, the second hanging column 613 does not move, which is relatively an upward movement process. The second hanging column 613 can enter the hanging point or unlock and leave the groove as long as the second hanging column 613 is cut by the upper inclined surface to exceed the edge of the step...

Abstract

The invention relates to a closed automobile exterior trimming cover type large-tension locking switch. A guide hanging shell is sleeved with a connecting shell, a guide groove is formed in the innerwall of the guide hanging shell, and an opening and closing device achieves opening and closing through cooperation of the guide groove and a second hanging column. A bidirectional self-holding electromagnetic lock is arranged on one side of the connecting shell. A locking block is arranged on the side, close to the opening and closing device, of the bidirectional self-holding electromagnetic lockand comprises a trapezoidal block and a square block. A limiting hole allowing the locking block to stretch out and draw back is formed in the connecting shell. A limiting block comprises a hole a and a hole b, a cover plate is arranged on one side of the guide hanging shell, and a locking hanging table is arranged on the portion, located in the guide groove, of the inner wall of the guide hanging shell. The guide groove comprises an initial guide groove body, a hanging block groove body, the locking hanging table and a first step. The first step and the hanging block groove body have a height difference, a first limiting step is arranged on the portion, close to one side, of the cover plate, and bouncing pin assemblies are installed at the two ends of the connecting shell. The pressing locking switch is simple and durable in structure, small in size, large in tension and low in cost.
