Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a battery clamp. Background Technology

[0002] Battery clamps are tools used to connect batteries to power sources or testing equipment, and are widely used in automobiles, electric vehicles, and other fields. In traditional battery clamp designs, the starter clamp and the test clamp are usually separate. The starter clamp is mainly used as a connection between the starter power supply and the car battery when the starter power supply is charging the car battery, while the test clamp is used to detect parameters such as battery voltage and current.

[0003] Because the existing battery clamps separate the starter clamp and the test clamp, users need to operate two battery clamps separately when they need to start and test the battery at the same time. Furthermore, because the clamping area of ​​the battery terminals is small, there is no clamping space on some battery models to clamp two battery clamps at the same time. Therefore, it is difficult to start the car and test the battery at the same time. Utility Model Content

[0004] In order to overcome at least one of the defects of the prior art, the present invention provides a battery clamp that can solve the problem that the existing battery clamp can only perform one of the functions of starting the car or testing the battery, and cannot perform both functions at the same time.

[0005] The technical solution adopted by this utility model to solve its problem is:

[0006] A battery clamp, comprising:

[0007] The first chuck has a first clamping part and a first gripping part at its two ends, and a first hinge part at its middle.

[0008] The second claw has a second clamping part and a connecting part at each end, and the connecting part is used to connect to an external battery detection circuit.

[0009] The third chuck has a third clamping part and a second gripping part at each end, and a second hinge part in the middle.

[0010] The first hinge portion is hinged to the second hinge portion, and the first claw and the third claw are electrically connected. The first clamping portion and the third clamping portion are correspondingly arranged to clamp the battery terminal. The first claw or the third claw is connected to an external vehicle starting circuit. The second clamping portion is arranged facing the third claw to cooperate with the third claw to clamp the battery terminal. The second claw is located between the first claw and the third claw. The first claw and the second claw are fixedly connected so that the second claw can move with the movement of the first claw. An isolation structure is provided between the first claw and the second claw to prevent the first claw and the second claw from being electrically connected.

[0011] Furthermore, it also includes a connecting wire. The third claw has a first connector at one end of the second gripping part. The external battery detection line and the external car start line are both connected to the connecting wire. The connecting wire has a second connector and a third connector. One end of the second connector is connected to the external battery detection line and the other end is connected to the connecting part. One end of the third connector is connected to the external car start line and the other end is connected to the first connector.

[0012] Furthermore, the first connector is a first connecting ear, and the third connector is a second connecting ear. The first connecting ear and the second connecting ear are fixed by a connecting rod passing through them.

[0013] Furthermore, the isolation structure is a first insulating plate, which is disposed between the first claw and the second claw.

[0014] Furthermore, it also includes a first insulating cover and a second insulating cover, wherein the first insulating cover covers the side of the first claw facing away from the second claw, and the second insulating cover covers the side of the third claw facing away from the first claw.

[0015] Furthermore, it also includes a second insulating plate and an assembly screw, wherein the assembly screw passes sequentially through the second insulating plate, the second claw, the first insulating plate, and the first claw before connecting to the first insulating cover.

[0016] Furthermore, the first insulating cover is made of PVT material, and / or the second insulating cover is made of PVT material.

[0017] Furthermore, the outer surface of the first insulating cover is provided with a first anti-slip structure, which is located at the corresponding position of the first insulating cover and the first grip portion. The outer surface of the second insulating cover is provided with a second anti-slip structure, which is located at the corresponding position of the second insulating cover and the second grip portion.

[0018] Furthermore, it also includes a torsion spring and a rotating shaft. The torsion spring includes a first torsion arm, a spring body, and a second torsion arm. The first torsion arm and the second torsion arm are respectively fixedly connected to both ends of the spring body. The rotating shaft passes through the first hinge portion, the spring body, and the second hinge portion in sequence, so that the first pawl and the second pawl can rotate around the rotating shaft. The first torsion arm abuts against the first gripping portion, and the second torsion arm abuts against the second gripping portion, so that the first torsion arm and the second torsion arm can push the first gripping portion and the second gripping portion to reset.

[0019] Furthermore, the third claw is provided with a snap-fit ​​hole, and the second insulating cover is provided with a snap-fit ​​buckle, which snaps into the snap-fit ​​hole.

[0020] In summary, the battery clamp provided by this utility model has the following technical effects:

[0021] The first clamping part of the first claw and the third clamping part of the third claw are arranged opposite each other to clamp the battery terminal. They connect to an external vehicle starting circuit via either the first or third claw to establish unipolar conduction in the vehicle starting circuit. The second clamping part of the second claw works in conjunction with the third claw to clamp the same battery terminal. The connecting part of the second claw connects to an external battery detection circuit to establish unipolar conduction in the battery detection circuit. That is, when the first clamping part of the first claw and the third clamping part of the third claw move relative to each other, the second claw, being fixedly connected to the first claw, moves with the first claw. This ensures that when the first and third clamping parts clamp the battery terminal, the second and third clamping parts also clamp the same terminal. This allows a single battery clamp to connect the battery terminal to both the external vehicle starting circuit and the battery detection circuit, ultimately maximizing the use of limited space and ensuring effective placement of two electrical connection points even in space-constrained conditions.

[0031] See Figures 1-4This utility model discloses a battery clamp, including a first jaw 1, a second jaw 2, and a third jaw 3. The first jaw 1 has a first clamping portion 11 and a first gripping portion 12 at its two ends, and a first hinge portion 13 in its middle. The second jaw 2 has a second clamping portion 21 and a connecting portion 22 at its two ends, the connecting portion 22 being used to connect to an external battery detection circuit. The third jaw 3 has a third clamping portion 31 and a second gripping portion 32 at its two ends, and a second hinge portion 33 in its middle. The first hinge portion 13 is hinged to the second hinge portion 33, and the first jaw 1 and... The third clamp 3 forms an electrical connection. The first clamping part 11 and the third clamping part 31 are correspondingly arranged to clamp the battery terminal. The first clamp 1 or the third clamp 3 is connected to the external car starting circuit. The second clamping part 21 is arranged facing the third clamp 3 to cooperate with the third clamp 3 to clamp the battery terminal. The second clamp 2 is arranged between the first clamp 1 and the third clamp 3. The first clamp 1 and the second clamp 2 are fixedly connected so that the second clamp 2 can move with the movement of the first clamp 1. An isolation structure is provided between the first clamp 1 and the second clamp 2 to prevent the first clamp 1 and the second clamp 2 from being electrically connected.

[0032] Specifically, the first claw 1 has a first clamping part 11 and a first gripping part 12 at both ends, and a first hinge part 13 in the middle. The first clamping part 11 is used to clamp the battery terminal and connect to the external car starting circuit. The second claw 2 has a second clamping part 21 and a connecting part 22 at both ends, and the connecting part 22 is used to connect to the external battery detection circuit. The second claw 2 is located between the first claw 1 and the third claw 3, and is fixedly connected to the first claw 1, so that the second claw 2 can move with the movement of the first claw 1. The third claw 3 has a third clamping part 31 and a second gripping part 32 at both ends, and a second hinge part 33 in the middle. The third clamping part 31 is correspondingly arranged with the first clamping part 11, and the third clamping part 31 and the first clamping part 11 work together to clamp the battery terminal. The third claw 3 and the first claw 1 form an electrical connection relationship, allowing current to pass through. An isolation structure is set between the first claw 1 and the second claw 2 to prevent electrical connection between the two and ensure safety. The first hinge 13 is hinged to the second hinge 33, allowing the first jaw 1 and the third jaw 3 to rotate around the pivot 94, thus achieving clamping or releasing. The first jaw 1 and the second jaw 2 are fixedly connected, ensuring that when the first jaw 1 moves, the second jaw 2 also moves accordingly, thereby maintaining synchronous clamping of the battery terminals by the two clamping parts.

[0033] The working principle of the above structure:

[0034] The first clamping part 11 and the third clamping part 31 are arranged opposite to each other for clamping the battery terminals. When the user grips the first gripping part 12 and the second gripping part 32, the first hinge part 13 and the second hinge part 33 rotate around the pivot 94, causing the first clamping part 11 and the third clamping part 31 to close and tightly clamp the battery terminals. One of the first claw 1 or the third claw 3 is connected to an external vehicle starting circuit to ensure that the starting current can be conducted to the battery terminals through these two clamping parts. The second claw 2 is located between the first claw 1 and the third claw 3 and is fixedly connected to the first claw 1, so it moves synchronously with the movement of the first claw 1. The second clamping part 21 of the second claw 2 is positioned facing the third claw 3. When the first claw 1 and the third claw 3 close to clamp the battery terminals, the second clamping part 21 also cooperates with the third claw 3 to clamp the same battery terminal. The connecting part 22 of the second claw 2 is connected to an external battery detection circuit.

[0035] That is, the battery terminal is positioned between the first clamping part 11 and the third clamping part 31, and between the second clamping part 21 and the third claw 3, so that through the relative movement of the first claw 1 and the third claw 3, the electrical connection between the first clamping part 11 and the third clamping part 31 to the battery terminal, as well as the electrical connection between the second clamping part 21 and the third claw 3, are completed simultaneously.

[0036] After the electrical connection is completed, the first claw 1 or the third claw 3 is connected to the external car starting circuit to conduct the starting current and realize the car starting function. While the second clamping part 21 cooperates with the third claw 3 to clamp the battery terminal, the connecting part 22 of the second claw 2 is connected to the external battery detection circuit, so as to detect the battery voltage, current and other parameters and provide battery status information.

[0037] In some embodiments, the battery clamp further includes a connecting wire 4, and the third claw 3 is provided with a first connector 34 at one end of the second gripping part 32. The external battery detection line and the external vehicle starting line are both connected to the connecting wire 4. The connecting wire 4 has a second connector 41 and a third connector 42. One end of the second connector 41 is connected to the external battery detection line and the other end is connected to the connecting part 22. One end of the third connector 42 is connected to the external vehicle starting line and the other end is connected to the first connector 34.

[0038] Specifically, the first connector 34 is located at one end of the second gripping portion 32 of the third claw 3, serving as a connection point to fix the third connector 42 in the connecting cable 4, facilitating connection with the third connector 42. One end of the second connector 41 is connected to an external battery testing circuit, and the other end is connected to the connecting portion 22 of the second claw 2, for transmitting the testing signal from the battery terminals to external testing equipment. One end of the third connector 42 is connected to an external vehicle starting circuit, and the other end is connected to the first connector 34 on the third claw 3, for conducting the starting current from the external power source to the battery terminals. The first and second connecting ears are fixed by a connecting rod 43 passing through them, ensuring the stability of the entire connecting cable 4 system and preventing loosening. The second connector 41 connects to the second claw 2 through the connecting portion 22, ensuring the electrical continuity of the testing circuit. The third connector 42 connects to the third claw 3 through the first connector 34, ensuring the electrical connection of the starting circuit.

[0039] In some embodiments, the first connector 34 is a first connecting ear, the third connector 42 is a second connecting ear, and the first connecting ear and the second connecting ear are fixed by passing through the connecting rod 43.

[0040] Specifically, the first and second connecting ears are fixed together by the connecting rod 43, providing a very stable mechanical connection point. This not only ensures that they will not easily loosen or fall off during use, but also withstands a certain amount of external force, enhancing the overall durability of the device. The connecting rod 43 can be any structure that can stably connect the first and second connecting ears, such as a rivet or screw, and is not limited here.

[0041] In some embodiments, the isolation structure is a first insulating plate 5, which is disposed between the first claw 1 and the second claw 2.

[0042] Specifically, the first insulating plate 5 is sandwiched between the first claw 1 and the second claw 2 to minimize the gap between the first claw 1 and the second claw 2. Compared with other types of isolation methods (such as air gaps), the insulating plate can fit tightly against the contact surfaces of the first claw 1 and the second claw 2, avoiding the generation of large gaps, thus saving space and ensuring a compact layout of the entire battery clamp.

[0043] In some embodiments, the battery clamp further includes a first insulating cover 61 and a second insulating cover 62, the first insulating cover 61 covering the side of the first claw 1 facing away from the second claw 2, and the second insulating cover 62 covering the side of the third claw 3 facing away from the first claw 1.

[0044] Specifically, the first insulating cover 61 and the second insulating cover 62 ensure that the user will not directly contact the first claw 1 and the third claw 3, which may be electrified, during operation.

[0045] In some embodiments, the battery clamp further includes a second insulating plate 8 and an assembly screw 7, the assembly screw 7 passing through the second insulating plate 8, the second claw 2, the first insulating plate 5 and the first claw 1 in sequence and then connecting to the first insulating cover 61.

[0046] Specifically, the assembly screw 7 passes through the second insulating plate 8, the second claw 2, the first insulating plate 5 and the first claw 1 in sequence and is then connected to the first insulating cover 61. This installation method simplifies the assembly structure and thus improves assembly efficiency.

[0047] In some embodiments, the first insulating cover 61 is made of PVT material, and / or the second insulating cover 62 is made of PVT material.

[0048] Specifically, PVT (Polyvinyl terephthalate) has extremely high insulation resistance, effectively preventing current leakage and ensuring that users will not come into contact with live parts during operation, greatly improving safety. More importantly, the softness of PVT material provides a better grip when holding the first insulating cover 61 or the second insulating cover 62.

[0049] In some embodiments, the outer surface of the first insulating cover 61 is provided with a first anti-slip structure 611, which is located at the corresponding position of the first insulating cover 61 and the first grip portion 12. The outer surface of the second insulating cover 62 is provided with a second anti-slip structure 621, which is located at the corresponding position of the second insulating cover 62 and the second grip portion 32.

[0050] Specifically, anti-slip textures or protrusions are provided on the outer surfaces of the first insulating cover 61 and the second insulating cover 62 to increase friction and make it less likely for the user to slip when holding the battery clamp.

[0051] In some embodiments, the battery clamp further includes a torsion spring 9 and a rotating shaft 94. The torsion spring 9 includes a first torsion arm 91, a spring body 92, and a second torsion arm 93. The first torsion arm 91 and the second torsion arm 93 are respectively fixedly connected to the two ends of the spring body 92. The rotating shaft 94 passes through the first hinge portion 13, the spring body 92, and the second hinge portion 33 in sequence, so that the first pawl 1 and the second pawl 2 can rotate around the rotating shaft 94. The first torsion arm 91 abuts against the first grip portion 12, and the second torsion arm 93 abuts against the second grip portion 32, so that the first torsion arm 91 and the second torsion arm 93 can push the first grip portion 12 and the second grip portion 32 to reset.

[0052] Specifically, the torsion spring 9 includes a first torsion arm 91, a spring body 92, and the torsion arms at both ends are fixedly connected to the spring body 92. The rotating shaft 94 passes through the first hinge part 13, the spring body 92, and the second hinge part 33 in sequence to fix the torsion spring 9 inside the device.

[0053] When the user grasps the first gripping part 12 and the second gripping part 32 and applies force to separate the first pawl 1 and the third pawl 3, the first torsion arm 91 is pushed by the first gripping part 12, and the second torsion arm 93 is pushed by the second gripping part 32, thereby compressing the first torsion arm 91 and the second torsion arm 93. When the user releases the first gripping part 12 and the second gripping part 32, the first torsion arm 91 and the second torsion arm 93 release their stored energy, pushing the first gripping part 12 and the second gripping part 32 back to their initial positions, thus achieving an automatic clamping or resetting function.

[0054] In some embodiments, the third claw 3 is provided with a snap-fit ​​hole 35, and the second insulating cover 62 is provided with a buckle 622, which is snapped into the snap-fit ​​hole 35.

[0055] Specifically, the design of the clip 622 and the snap-fit ​​hole 35 allows for quick installation and removal between the second insulating cover 62 and the third claw 3 without the need for additional tools or fasteners, greatly simplifying the assembly process. Furthermore, the user can easily insert the clip 622 into the snap-fit ​​hole 35 with a simple pushing motion, ensuring a secure connection between the two components and reducing assembly time and complexity.

[0056] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
