Description

Technical Field

[0001] The utility model belongs to the technical field of automobile accessories, and in particular relates to an automobile USB charging port structure with an anti-falling function. Background Art

[0002] The function of the car USB port is to utilize the standard power supply in the car to charge electrical appliances using USB as the interface, or to be used as a fixed power interface power supply.

[0003] At present, a USB anti-falling interface board structure is disclosed in China, and the application number is CN202321569372.7, which specifically discloses a USB anti-falling interface board structure, including a USB interface board, the top of the USB interface board is fixedly connected with a fixed box, the interior of the fixed box is longitudinally movably connected with a support rod, the surface of the support rod is fixedly connected with a gear, the right side of the gear is meshed with a first tooth plate, the left side of the gear is meshed with a second tooth plate, the top of the second tooth plate is fixedly connected with a moving block, the top of the moving block is slidably connected to the top of the fixed box, the bottom of the second tooth plate is fixedly connected with a spring, the interior of the fixed box is longitudinally fixedly connected with a support plate, the bottom of the spring is fixedly connected to the top of the support plate, the bottom of the first tooth plate is fixedly connected with a moving plate, the bottom of the moving plate is fixedly connected with a movable block, the bottom of the movable block is fixedly connected with a suction cup, and the bottom of the movable block The part penetrates into the interior of the USB interface board, and a limiting component is arranged inside the fixed box. The application is that before plugging in the connector, the user presses the moving block, and the moving block drives the second tooth plate to move downward, and the second tooth plate presses the spring downward, and at the same time, the second tooth plate drives the gear to rotate, and the gear drives the first tooth plate to move upward, and the first tooth plate drives the moving plate to move up and down, and at the same time drives the suction cup to move upward. Then, the user inserts the connector into the interior of the USB interface board, and the user releases the moving block, and the spring rebounds to reset the first tooth plate, so that the suction cup presses and fixes the top of the connector to prevent it from falling off, so that the USB interface board can achieve the effect of preventing it from falling off, replacing the existing method of not fixing the connector, thereby achieving a structure with a clamping structure for the connector to avoid shaking and falling off, which is convenient for users to use. However, the internal components of the application will be designed to be extremely small due to the overall volume limitation of the USB interface, which increases the difficulty of manufacturing and generation, and is difficult to actually generate.

[0004] The existing USB interface has at least one movable hole 100 on the four side walls of its body. A retaining spring 200 for clamping the male head is arranged at the movable hole 100. The retaining springs 200 on two adjacent surfaces are arranged relative to the connection point (bending point) of the body. When the male head is inserted, the retaining spring 200 is deformed by the driving force. The closer the deformation amplitude is to the connection point 300, the smaller the amplitude. After long-term use, the elastic potential energy of the retaining spring 200 is reduced, and then the clamping force is reduced, resulting in looseness between the male head and the female head, which is very easy to fall off.

[0007] Furthermore, the sliding body is an annular body, and the sliding body is sleeved on the USB body.

[0008] Furthermore, the sliding body is a U-shaped body, and the end of the sliding body is bent toward the movable hole opened in the side wall of the USB body.

[0009] Furthermore, the driving body is specifically a bolt, a limiting ring is arranged on the bolt, a limiting ring groove is arranged in the fixed body, the limiting ring is placed in the limiting ring groove, and the bolt passes through the fixed body and is threadedly connected to the sliding body.

[0010] Furthermore, the sliding body is provided with an extension portion, the extension portion is provided with an internal thread block, and the internal thread block is used in conjunction with the bolt.

[0011] Furthermore, the end of the extension portion is connected to the middle portion of the sliding body.

[0013] Beneficial effects:

[0014] The present application provides a movable sliding body on the USB body. The position of the sliding body relative to the USB body determines the bending point of the retaining spring when it is deformed. By changing the bending point, the pressure between the USB male and female heads is increased or decreased, thereby increasing the friction force. Ultimately, the technical problem of the USB being easily dropped off can be solved.

[0015] The present application can realize the movement of the sliding body by providing a driving body, and thus the bending point of the clip spring can be adjusted at any time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 3As shown, a car USB charging port structure with an anti-falling function comprises: a USB body 1, on which a limiting part 2 for redefining the bending point of a clip 200 is slidably arranged. The limiting part 2 comprises a fixed body 20, a driving body 21 and a sliding body 22. The fixed body 20 is mounted on the USB body 1 and is used to establish a connection with the vehicle body. The driving body 21 is movably arranged on the fixed body 20 and is used to drive the sliding body 22 to slide on at least one outer wall surface of the USB body 1. The sliding body 22 is an annular body, and the sliding body 22 is sleeved on the USB body 1. The sliding body 22 is a U-shaped body, and the end of the sliding body 22 is bent toward the movable hole 100 opened on the side wall of the USB body 1. The driving body 21 is specifically a bolt 211, on which a limiting ring 212 is arranged, and a limiting ring groove 213 is arranged in the fixed body 20, and the limiting ring 212 is placed in the limiting ring groove 213, and the bolt 211 passes through the fixed body 20 and is threadedly connected to the sliding body 22. The sliding body 22 is provided with an extension part 23, and the extension part 23 is provided with an internal thread block 24, and the internal thread block 24 is used in conjunction with the bolt 211. The end of the extension part 23 is connected to the middle of the sliding body 22. The extension part 23 and the sliding body 22 are integrally formed.

[0024] Among them, the material of the fixed body 20 can be hard environmentally friendly plastic or stainless steel, and its shape is a ring arranged around the USB body. A hole position connected to the car body is set on the fixed body 20 (not shown in the figure). The fixed body 20 and the USB body are bonded or welded by colloid. The fixed body 20 can also be the shell of the car body. The fixed body 20 only provides a positioning carrier for the driving body 21; when the sliding body 22 is annular, it is two, and the retaining springs on the two adjacent surfaces of the USB body are phased respectively.
