Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted data cables, in particular to a vehicle-mounted data cable with a changeable use length. Background Art

[0002] The car data cable is a charging cable for mobile electronic products commonly used in cars. With the popularity of portable electronic products, especially mobile phones, cameras, and IPDs, a car data cable is generally placed in the car for use when the electronic products need to be charged.

[0003] In the prior art, when charging some cars, the cigarette lighter adapter is first installed in the vehicle's cigarette lighter interface for connection, and then the data cable is inserted into the cigarette lighter adapter for connection. Since the data cable and the cigarette lighter adapter are scattered parts, the data cable is tangled after use and is easily damaged. There is no storage function. When a passenger needs to use a mobile phone during charging, the mobile phone is disconnected from the charger. At this time, the plug is still in the power interface, and the output end of the data cable falls randomly onto the foot mat in the car. If a passenger accidentally steps on the output end of the data cable, it will cause damage to the output end. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and provides a vehicle-mounted data cable with a variable length.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a wire winding box, the upper end surface of the wire winding box is provided with a sealing cover, the inside of the wire winding box is fixed with a rotating shaft, the outer wall of the rotating shaft is rotatably connected with a wire take-up device, the bottom end surface of the wire take-up device is fixed with a rotating spring, the other end surface of the rotating spring is fixedly connected with the inner wall of the wire winding box, the upper end surface of the wire take-up device is provided with a latching tooth, the upper end surface of the sealing cover is fixed with a fixer, the inner wall of the fixer is fixed with a buffer spring, the upper end surface of the buffer spring is fixed with a pad, the upper end surface of the pad is fixed with a movable column, the other end of the pad is fixed with a fixing pin, and the inner wall of the fixer is fixed with a supporting column. In the prior art, when charging some cars, the cigarette lighter conversion head will be first installed in the cigarette lighter interface of the vehicle for connection, and then the data cable will be inserted into the cigarette lighter conversion head for connection. Since the data cable and the cigarette lighter conversion head are scattered parts, the data cable will be tangled after use and easily damaged, and there is no storage function. During the charging process When the passenger needs to use the mobile phone, the mobile phone is disconnected from the charger. At this time, the plug is still in the power interface, and the output end of the data cable falls onto the foot mat in the car at will. If the passenger accidentally steps on the output end of the data cable, it will cause damage to the output end. By connecting the data cable to the cable receiver, when the passenger needs to charge, the data cable is dragged according to the distance of the customer, driving the cable receiver to rotate on the rotating shaft, and also applying elastic force to the rotating spring. At the same time, the fixed latch rotates at the upper end of the cable receiver. When it reaches the appropriate position, release your hand, and the rotating spring rotates due to its elasticity. At the same time, the fixed latch presses against the latch teeth to lock the cable receiver to prevent the spring from rotating. When charging is completed, press the movable column to drive the pad to move downward, and at the same time, the other end of the pad moves upward on the support column to lift the fixed latch upward. When the height exceeds the latch teeth, the elastic force accumulated by the rotating spring is released, and the data cable is automatically wound around the cable receiver, thereby preventing the data cable from being damaged due to the passenger's random placement after charging, and protecting the vehicle-mounted data cable.

[0006] Preferably, a sealing sleeve is embedded in the side wall of the winding box, a spiral button is threadedly connected to the outer wall of the sealing sleeve, an insulating sleeve is sleeved on the inner wall of the sealing sleeve, a buffer ring is fixed to the outer surface of the insulating sleeve, a light strip is fixed to the outer wall of the front end of the insulating sleeve, a rotator is fixed to the front end of the insulating sleeve, and a USB interface is rotatably connected to the inner wall of the rotator. The existing vehicle-mounted data cable does not protect the data cable when it is wound, resulting in damage to the data cable due to the impact generated by the recovery, which will cause data breakage problems in the long run. By installing a buffer pad at the front end of the insulating sleeve, the buffer ring buffers the retraction force when the data cable is recovered, thereby avoiding the problem that the vehicle-mounted data cable does not protect the data cable when it is wound, resulting in damage to the data cable due to the impact generated by the recovery, which will cause data breakage problems in the long run.

[0007] Preferably, fixing bolts are threadedly connected on both sides of the outer wall of the winding box, and heat sinks are fixed to the end faces of both sides of the winding box by fixing bolts, and heat dissipation grooves are provided on the surface of the heat sink. Nowadays, as the power of the data cable increases, the heat generation increases. If the heat dissipation problem is not properly solved, the heat will be concentrated in a device with a very small size, which is easy to cause concentrated heating, and the data cables are rolled up together, which is not conducive to air flow. The heat generated by the data cables gathers together, making the temperature inside the device higher and higher. If the heat cannot be evacuated in time, the charging efficiency will be affected, and even the data cable short circuit problem will be caused. The utility model adds heat dissipation slots inside the device to increase the air flow in the device, and the heat generated by the protective device is sent out from the heat sink with the help of air flow, thereby optimizing the heat dissipation of the data cable, reducing the possibility of wire burning, and extending the service life of the data cable.

[0008] Preferably, a rubber cushion is provided at the top of the movable column, and the comfort of the rubber cushion can prevent passengers' fingers from being injured when the data cable is rolled up.

[0009] Preferably, a plurality of grooves are provided inside the cable take-up device, and by adding a plurality of grooves, the heat dissipation is increased when the data cables are wound together.

[0010] Preferably, the buffer ring is made of rubber material, and the elasticity of the rubber material is used to increase the service life of the buffer ring.

[0011] Preferably, the heat dissipation slots are distributed obliquely, and the heat dissipation holes are arranged in a V-shape, thereby achieving a dust-proof effect and preventing dust from entering the winding box.

[0012] Beneficial Effects

[0013] 1. In the prior art, when charging some cars, the cigarette lighter adapter is first installed in the cigarette lighter interface of the vehicle for connection, and then the data cable is inserted into the cigarette lighter adapter for connection. Since the data cable and the cigarette lighter adapter are scattered parts, the data cable is tangled after use and is easily damaged. There is no storage function. When the passenger needs to use the mobile phone during the charging process, the mobile phone is disconnected from the charger. At this time, the plug is still in the power interface, and the output end of the data cable falls on the foot mat in the car at will. If the passenger accidentally steps on the output end of the data cable, it will cause damage to the output end. The utility model connects the data cable with the cable receiver. When the passenger needs to charge, according to the customer Drag the data cable a distance to drive the cable receiver to rotate on the shaft, and also apply elastic force to the rotating spring. At the same time, the fixed pin rotates on the upper end of the cable receiver. When it reaches the appropriate position, release your hand. Due to the elasticity of the rotating spring, it rotates back. At the same time, the fixed pin presses against the tooth to lock the cable receiver to prevent the spring from rotating. When charging is completed, press the movable column to drive the pad to move down. At the same time, the other end of the pad moves upward on the support column to lift the fixed pin upward. When the height exceeds the tooth, the elastic force accumulated in the rotating spring is released, and the data cable is automatically wound around the cable receiver, thereby avoiding damage to the data cable due to passengers placing it randomly after charging, and protecting the on-board data cable.

[0014] 2. In the prior art, the existing vehicle-mounted data cable does not protect the data cable when it is being retracted, resulting in damage to the data cable due to the impact generated by the retraction. In the long run, the problem of data breakage will occur. The utility model installs a buffer pad at the front end of the insulating sheath wire. When the data cable is retracted, the buffer ring buffers the retraction force, thereby avoiding the problem that the vehicle-mounted data cable does not protect the data cable when it is being retracted, resulting in damage to the data cable due to the impact generated by the retraction. In the long run, the problem of data breakage will occur.

[0015] 3. In the prior art, as the power of the data line increases, the heat generated increases. If the heat dissipation problem is not properly solved, the heat will be concentrated in a very small device, which is easy to cause concentrated heating. In addition, the data lines are rolled up, which is not conducive to the flow of air. The heat generated by the data lines gathers together, making the temperature inside the device higher and higher. If the heat cannot be evacuated in time, the charging efficiency will be affected, and even the data line short circuit problem will be caused. The utility model adds heat dissipation slots inside the device to increase the air flow in the device, and the heat generated by the protection device is sent out from the heat sink with the help of air flow, thereby optimizing the heat dissipation of the data line, reducing the possibility of wire burning, and extending the service life of the data line.
