Description

Technical Field

[0001] The present invention belongs to the field of connecting an automotive power line to a battery, and particularly relates to a non-detachable battery post clamp for automobiles. Background Art

[0002] In current automobiles, whether fuel-powered or new energy vehicles, a very rich variety of electronic systems are installed on the vehicle: such as electronic anti-theft systems, electronic sensing systems, etc. Especially in the sentry mode, after the vehicle is locked, the sentry mode continuously monitors the surrounding environment through the front-view camera, side cameras, rear-view camera, and induction radar. Whether an electric vehicle or a fuel vehicle is parked without use, the battery will consume power due to these functions. According to actual measurements, turning on the sentry mode for 12 hours consumes approximately 20 kilometers of battery life and about 3 - 5 degrees of electricity. Taking a battery with a capacity of 75 degrees as an example, it can only last for about two weeks after conversion.

[0003] To avoid battery damage caused by the power battery running out of power, first, try to avoid not starting the vehicle for a long time. As long as the vehicle is started (similar to starting the engine of a fuel vehicle), the power battery will supply power to the small battery, providing a power source for the low-power systems of the vehicle; second, if it is really unavoidable to park for a long time, then charge the vehicle's battery to 80%, and do not let the battery level drop below 20% to avoid serious power loss due to the low battery level itself and self-discharge, which will affect the battery life.

[0004] In the prior art, the method to prevent the vehicle from running out of power when not driving for a long time is: the car battery can be removed and stored in a cool and dry place. If you don't want to remove the entire battery, at least separate the negative terminal of the wiring post. It is recommended to start the vehicle once within half a month or idling in place is also okay. If the vehicle is parked for more than five days, the negative terminal of the battery should be disconnected. In principle, a vehicle parked for more than 15 days is considered long-term parking. If the battery runs out of power completely, not only the engine cannot be started, but it may also cause problems such as the loss or reset of the vehicle computer data, the failure of the window lifter, and the locking of the anti-theft system. If conditions permit, try to let the vehicle idle in place for 10 to 20 minutes to ensure that the battery does not run out of power.

[0005] In summary, in the prior art, there are only two ways to prevent the automotive battery from running out of power: removing the power connection line and regularly charging the battery.

[0006] However, when removing the power connection line, since the vehicle does not have a fixing device for the power line, the power line is in a free state near the battery, which easily connects to the battery and causes a sparking phenomenon, posing a relatively large safety hazard and being inconvenient to operate. Summary of the Invention

[0007] The objective to be achieved by the present invention is to solve the technical problem that when disassembling the power connection line, since the vehicle does not have a fixing device for the power line, the power line is in a free state near the battery, which easily connects to the battery and causes a sparking phenomenon, posing a significant safety hazard.

[0008] To achieve the above objective, the present invention provides a battery post clip for automobiles that does not require disassembly.

[0009] The specific technical solution adopted by the present invention is as follows:

[0010] A battery post clip for automobiles that does not require disassembly, used to connect the power line of a vehicle electrical appliance to the battery, includes a base handle and a locking device fixed to the front end of the base handle:

[0011] The base handle is provided with an insulating housing, and a wire is provided inside the housing. One end of the wire is connected to the power line of the vehicle electrical appliance, and the other end of the wire is connected to a first locking device.

[0012] The locking device is fixed to the end of the base handle that is not connected to the power line, and includes an interlocking handle, a first locking device, and a second locking device coaxial with the first locking device;

[0013] Both the first locking device and the second locking device are provided with an annular frame, and a plurality of fixing blocks are slidably arranged inside the annular frame. The fixing blocks slide along the annular frame towards the center or the periphery of the annular frame to achieve locking or releasing of the battery post;

[0014] The fixing block is connected to the interlocking handle through a connecting rod. When the interlocking handle is locked to one side, the connecting rod drives the fixing block of the first locking device to slide towards the center of the annular frame, the first locking device locks the battery post, and the fixing block of the second locking device slides towards the periphery of the annular frame, and the second locking device releases the battery post, realizing power supply from the battery to the vehicle electrical appliance. Conversely, the first locking device releases the battery post, and the second locking device locks the battery post, realizing power cut-off from the battery to the vehicle electrical appliance.

[0015] With such a design, the power line of the vehicle electrical appliance is connected to the first locking device through a wire. By controlling the first locking device and the second locking device through the interlocking handle, the first locking device and the second locking device are alternately locked on the battery post. When the first locking device locks the battery post, the power line of the vehicle electrical appliance is connected to the battery post via the wire and the fixing block of the first locking device, realizing power conduction. At this time, the second locking device is in a released state and does not contact the battery post; when the second locking device locks the battery post, the first locking device is in a released state and does not contact the battery post, realizing power disconnection; it realizes the disconnection of the power line and the battery without disassembly. In the case where the vehicle is not driven for a long time, it avoids the depletion of the battery's power, thereby ensuring the vehicle can start smoothly again and is more convenient to operate.

[0016] As a further improvement of the present invention, the connecting rod is provided with a dead point. When the interlocking handle is locked to one side, before the dead point, the fixing block contacts the battery terminal post, and after the dead point, the fixing block maintains a fixed locking force with the battery terminal post.

[0017] Through such a design, by setting the dead point, when the interlocking handle is fully locked, it can be prevented from loosening due to vibration. Only when an external force acts on the interlocking handle can the locking state be released.

[0018] As a further improvement of the present invention, there are two interlocking handles, which are symmetrically arranged on both sides of the symmetric base handle.

[0019] As a further improvement of the present invention, a first hinge seat is provided in the middle of the base handle. The first hinge seat is hinged with the first connecting rod of the interlocking handle. The other end of the first connecting rod is hinged with a handle. The hinged end of the handle and the first connecting rod is also hinged with a second connecting rod. The other end of the second connecting rod is hinged with the base handle. A T-shaped groove is also provided at the hinged end of the first connecting rod and the handle. The two symmetric T-shaped grooves are connected together by a sliding third connecting rod. The third connecting rod is hinged with the driving connecting rod of the fixing block of the first locking device, and the third connecting rod is also hinged with the driving connecting rod of the fixing block of the second locking device.

[0020] Through such a design, the dead point is set on the movement trajectory of the hinge point between the first connecting rod and the handle. Specifically, at the hinge point between the first connecting rod and the handle, the handle is designed in the form of an eccentric cam. By changing the eccentric distance, the handle can further press the first connecting rod.

[0021] As a further improvement of the present invention, the handles of the two interlocking handles are movably connected by a fourth connecting rod. The fourth connecting rod is inserted into the side part of the base handle. A shear thickening fluid STF is provided at the mating part of the fourth connecting rod and the base handle. When the vehicle is in the starting state, the shear thickening fluid STF becomes solid to prevent the handle from loosening during vibration.

[0022] Among them, the shear thickening fluid STF is composed of polyethylene glycol and silicon microparticles. Polyethylene glycol is a widely used non-toxic liquid that can withstand a wide temperature range. Extremely fine silicon microparticles are another component of STF. When the movement is slow, the hard particles can move everywhere, and the shear thickening fluid STF presents a liquid state. However, when the movement is rapid, the hard particles collide with each other, hindering each other's movement, and the shear thickening fluid STF becomes tough. After this highly fluid liquid is combined with hard microparticles, it can form a rigid material. When the vibration weakens or disappears, the shear thickening fluid STF returns to the liquid state again.

[0023] Therefore, the vibration after the vehicle starts is ultimately transmitted into the shear thickening fluid STF, and is absorbed by the shear thickening fluid STF for its transformation from a liquid state to a solid state, playing a role in fixing the fourth connecting rod. When the vehicle shuts off, since the vibration is not continuously supplied, the shear thickening fluid STF returns to its liquid state again, and the fixing effect of the thickening fluid STF on the fourth connecting rod disappears, facilitating the movement of the interlocking handle.

[0024] In addition, such a design can also prevent the battery terminal clamp from loosening due to vibration after the vehicle starts, avoiding poor contact at the battery terminal clamp and affecting the power consumption of in-vehicle electrical appliances.

[0025] As a further improvement of the present invention, a circular through hole is provided at the front end of the base handle, and two annular sliding grooves are symmetrically provided in the through hole. The annular frames of the first locking device and the second locking device are movably arranged in the sliding grooves.

[0026] The annular sliding grooves provide an installation and fixing space for the first locking device and the second locking device. At the same time, they also provide a rotating track for the annular frames in the first locking device and the second locking device, facilitating the annular frames to drive the fixing blocks to clamp or loosen the battery terminals by rotating.

[0027] As a further improvement of the present invention, a coaxial guiding ring is fixed inside the annular frame. A spiral guiding groove is provided on the guiding ring. A fixing block is slidably arranged on one side of the guiding ring. The fixing block slides in the guiding groove, and the annular frame is hinged to the fixing block through a plurality of arc-shaped connecting rods.

[0028] The coaxial guiding ring provides a sliding platform for the fixing block, and the coaxial design enables the circular motion of the annular frame to be evenly transmitted to each fixing block, driving the fixing block to clamp or loosen the battery terminal. A spiral refers to the trajectory of any moving point that rotates around a center point while gradually moving away from the center. The provision of a spiral guiding groove facilitates the tightening of the fixing block towards the center of the annular frame or the loosening away from the center of the annular frame.

[0029] As a further improvement of the present invention, a first driving connecting rod is hinged to the annular frame of the first locking device, and a second driving connecting rod is hinged to the annular frame of the second locking device. The first driving connecting rod and the second driving connecting rod are jointly hinged on a driving hinge shaft. The driving hinge shaft is hinged to the third connecting rod, and drives the annular frames of the first locking device and the second locking device to rotate in opposite directions through the third connecting rod.

[0030] Through the first driving link and the second driving link, two annular frames are simultaneously connected to the third link, and the third link drives the two annular frames to rotate simultaneously, and the rotation directions are opposite. In this way, when the first locking device is locked, the second locking device is in a loosened state, that is, the conversion of the disconnection and conduction of the power cord and the battery is realized without disassembly.

[0031] As a further improvement of the present invention, the third link is provided with a slotted groove, and the driving hinge shaft is connected in the slotted groove.

[0032] The third link drives the first driving link and the second driving link to move by connecting the driving hinge shaft in the slotted groove, avoiding the phenomenon of jamming.

[0033] As a further improvement of the present invention, the driving hinge shaft is connected in the slotted groove through a sliding plate.

[0034] Connecting in the slotted groove through the sliding plate further optimizes the mechanism for preventing the first driving link and the second driving link from jamming. At the same time, while realizing the sliding and hinging of the first driving link and the second driving link with the slotted groove, a larger rotation angle is provided for the annular frame.

[0035] The positive effects of the present invention are:

[0036] The disconnection of the power cord and the battery is realized without disassembly. When the vehicle is not driven for a long time, the power consumption of the battery is avoided, so as to ensure the smooth restart of the vehicle and make the operation more convenient.
