Description

Technical Field

[0001] The invention relates to the field of automobile emergency starting equipment, in particular to an automobile emergency starting battery cable. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] When the car battery fails, it is usually impossible to start the vehicle. Manual transmission models can usually be started by pushing the car to passively drive the engine to rotate. However, automatic transmission models have a torque converter and the gearbox and engine are not rigidly connected, so the car cannot be started by pushing the car. In this case, the only way to start the faulty vehicle is to use an emergency starting battery cable to connect an external power supply.

[0004] The specific steps of external power jumper starting are as follows: 1. Connect the positive pole of the battery of the rescued car to the positive pole of the rescue vehicle; 2. Connect the negative pole of the battery of the rescue vehicle to the negative pole of the battery of the rescued car. This operation must be connected in strict order to prevent the positive and negative poles from short-circuiting; 3. After the vehicle is started, remove the jumper in the order of positive first and negative later. When using the car emergency starting battery line to connect the faulty car and the external power supply, it is easy for improper manual operation to cause reverse connection and short circuit, causing damage to the car. Therefore, an overcurrent protection device is often set. The existing overcurrent protection device is difficult to replace after it is blown, which brings inconvenience to the operation.

[0005] Since both ends of the starting battery cable need to be provided with clamping structures to clamp on the electrode head of the battery, wear is prone to occur, resulting in a relatively smaller contact area between the clamping structure and the electrode head, which increases the resistance of the battery cable and the energy consumption, causing inconvenience in use. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the embodiments of the utility model is to provide a car emergency starting battery cable to at least solve one of the above problems.

[0007] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solutions:

[0008] An automobile emergency starting battery cable, comprising:

[0009] A clamping structure, a cable and a bolt assembly, wherein both ends of the cable are fixed with a clamping structure;

[0010] The clamping structure includes two metal clamping plates, one end of which is fixedly connected to the cable, and the two clamping plates are connected by a hinge structure, in which a torsion spring is arranged; a detachable clamping metal sheet is arranged on the opposite side of the two clamping plates, and the clamping metal sheet is fixed to the clamping plate by a bolt assembly.

[0011] The utility model uses the cable as a conductor, and by pinching the tail ends of the two clamping plates, the clamping plates overcome the force of the torsion spring and open, and then use the force of the torsion spring to clamp the battery, and directly connect the connector and the cable through the clamping metal sheet. Since the inner side of the clamping plate clamps and contacts the electrode head of the battery, it is easy to wear. The utility model is provided with a detachable clamping metal sheet, and the detachable clamping metal sheet is fixed to the clamping plate by a bolt assembly. When the clamping metal sheet is worn after long-term use, the bolt assembly is loosened, the worn clamping metal sheet is taken out, and a new clamping metal sheet is replaced, so that it is easy to repair and replace, and saves costs.

[0012] In some embodiments, an overvoltage protection structure and an overcurrent protection structure are connected in series on the cable.

[0013] In some embodiments, the overcurrent protection structure includes a mounting shell, a protective cover and a fuse. An elastic hook is provided at the bottom of the protective cover, and a slot corresponding to the elastic hook is provided on the inner side of the mounting shell. The elastic hook is engaged in the slot to fix the protective cover on the mounting shell.

[0014] Through the above structure, the elastic hook is clamped in the clamping groove of the mounting shell to achieve fixed connection between the mounting shell and the protective cover. The above structure is convenient for disassembly or installation of the protective cover, making replacement of the fuse more convenient.

[0015] In some embodiments, two slots are provided at the bottom of the mounting shell, the two slots are respectively connected to the cables, the fuse is inserted into the two slots, and the electrical connection between the fuse and the cable is achieved through the slots.

[0016] In some embodiments, one end of the clamping plate is fixedly connected to the cable through a connector.

[0017] In some embodiments, an insulating sleeve is provided at one end of the clamping plate close to the cable, and the insulating sleeve is fixedly sleeved on the clamping plate.

[0018] In some embodiments, the clamping metal sheet is a T-shaped structure that is thick in the middle and thin at both sides.

[0019] In some embodiments, a T-shaped groove corresponding to the shape of the clamping metal sheet is provided on the inner side of the clamping plate, and the clamping metal sheet is inserted into the T-shaped groove of the clamping plate. The T-shaped groove further fixes the clamping metal sheet on the clamping plate, prevents the clamping metal sheet from falling, and increases the contact area between the clamping plate and the clamping metal sheet.

[0020] In some embodiments, through holes are provided at corresponding positions on the clamping metal sheet and the clamping plate, and the bolt assembly passes through the through holes to clamp the clamping metal sheet on the clamping plate.

[0021] In some embodiments, the clamping metal sheet is a clamping copper sheet, and the clamping plate is a copper plate.

[0022] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages:

[0023] 1. The emergency starting battery line of the car is connected to the electrode head and the cable through a clamping structure. The clamping structure is clamped on the electrode head of the battery. The inner side of the clamping structure is prone to wear after long-term use. The utility model forms a clamping structure by arranging a detachable clamping metal sheet fixed on a clamping plate, and clamps the clamping metal sheet on the clamping plate through a locking bolt assembly. When the clamping metal sheet is worn, it is only necessary to remove the bolt assembly to take out the clamping metal sheet and then replace it with a new clamping metal sheet, thereby achieving good conductivity while being easy to repair and saving costs.

[0031] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0032] As introduced in the background technology, the overcurrent protection device of the automobile emergency starting battery line in the prior art is difficult to replace after it is blown, or the inner side of the clamping structure is easily worn, which brings inconvenience to use. In order to solve the above technical problems, the utility model proposes an automobile emergency starting battery line.

[0033] like Figure 1 As shown, one or more embodiments of the utility model record an automobile emergency starting battery cable, including a clamping structure and a cable 1, the clamping structure is fixed at both ends of the cable 1, and the cable 1 is also connected in series with an overvoltage protection structure 8 and an overcurrent protection structure 15. The clamping structure is fixedly connected to the cable 1 through a connector 2 to achieve electrical connection between the clamping structure and the cable 1, and the overvoltage protection structure is implemented using an existing overvoltage protection device, such as a BF02 overvoltage protector.

[0034] The clamping structure includes a clamping plate 1 3 and a clamping plate 2 5, which are arranged up and down and rotatably connected by a hinge structure, and a torsion spring 4 is arranged in the hinge structure; wherein one end of the clamping plate 1 3 is fixedly connected to the cable 1 through a connector 2. Under the action of the torsion spring 4, one end of the clamping plate 1 3 and the clamping plate 2 5 are brought close to each other to form a clamping head, and the other ends are moved away from each other to form an operating portion. The clamping plate 1 3 and the clamping plate 2 5 are both made of metal conductive materials. In some embodiments, the materials of the clamping plate 1 3 and the clamping plate 2 5 are preferably copper.

[0035] Removable clamping metal sheets 6 are provided on the inner sides of the two clamping plates, and the clamping metal sheets 6 are fixed to the clamping plates by bolt assemblies 7. In a preferred embodiment, through holes are provided at corresponding positions of the clamping metal sheets 6 and the clamping plates, and the bolt assemblies 7 include bolts and nuts, and the bolts pass through the through holes, and the bolts and nuts cooperate to clamp the clamping metal sheets 6 to the clamping plates; in another preferred embodiment, the clamping metal sheets 6 are clamping copper sheets.

[0036] like Figure 3 As shown, the clamping metal sheet 6 is set as a T-shaped structure with a thick middle and thin sides, and the inner side of the clamping plate, that is, the side opposite to the clamping plate 1 3 and the clamping plate 2 5, is provided with a T-shaped groove corresponding to the shape of the clamping metal sheet 6, and the clamping metal sheet 6 is inserted into the T-shaped groove of the clamping plate. The clamping metal sheet 6 is further fixed to the clamping plate to prevent the clamping metal sheet from falling, while increasing the contact area between the clamping plate and the clamping metal sheet.

[0037] like Figure 1As shown, the end of the clamping plate 1 3 and the clamping plate 2 5 close to the cable is the tail end, and the tail ends of the clamping plate 1 3 and the clamping plate 2 5 are both sleeved with an insulating sleeve 14, and the insulating sleeve 14 is fixedly sleeved on the end of the tail end of the clamping plate, so that maintenance personnel can apply force to the operating part to prevent leakage of the operating part.

[0038] In a preferred embodiment, the specific structures and connection methods of the clamping structures at both ends of the cable 1 are the same.

[0039] By applying relative forces to the tail ends of the clamping plates 1 3 and 2 5, the elastic force of the torsion spring 4 in the opposite direction is overcome, so that the other ends of the clamping plates 1 3 and 2 5 are opened, and the tail ends are loosened. The elastic force of the torsion spring 4 clamps the clamping structure on the electrode head. The clamping metal sheet 6 is inserted into the T-shaped groove of the clamping plate and the bolt assembly 7 is set. On the one hand, the clamping metal sheet 6 is tightly attached to the clamping plate, increasing the contact area between the clamping metal sheet 6 and the clamping plate, thereby reducing the energy consumption of the battery line; on the other hand, it is convenient to replace and repair the worn clamping metal sheet 6.

[0040] like Figure 2 As shown, the overcurrent protection structure 15 includes a mounting shell 9 , a protection cover 13 and a fuse 11 . The mounting shell 9 is a box-shaped structure with an upper opening, and the protection cover 13 is installed at the upper opening of the mounting shell 9 .

[0041] An elastic hook 12 is installed at the bottom of the protective cover 13 , and a slot 16 corresponding to the elastic hook 12 is provided on the inner side of the mounting shell 9 . The elastic hook 12 is engaged in the slot 16 to fix the protective cover 13 on the mounting shell 9 .

[0042] Two slots 10 are provided at the bottom of the installation shell 9 . The two slots 10 are electrically connected to the cable 1 respectively. The fuse 11 is inserted into the two slots 10 . The electrical connection between the fuse 11 and the cable 1 is achieved through the slots 10 .

[0043] Through the above structure, the elastic hook 12 is stuck in the slot 16 of the mounting shell 9 to achieve a fixed connection between the mounting shell 9 and the protective cover 13. The above structure is convenient for disassembly or installation of the mounting shell 9 and the protective cover 13, and for replacement of the fuse 11.

[0044] The utility model uses the cable 1 as a conductor, and by pinching the tail ends of the two clamping plates, the clamping plates are opened to overcome the elastic force of the torsion spring 4, and then the clamping structure is clamped on the electrode head by the elastic force of the torsion spring 4. When the clamping copper sheet 6 is worn after long-term use, it is only necessary to unscrew the nut, remove the bolt assembly 7, and then slide the clamping copper sheet 6 out of the groove of the clamping plate, replace it with a new clamping copper sheet 6, and then install and tighten the nut of the bolt assembly 7 to achieve the replacement of the clamping copper sheet.

[0045] The protective cover 13 is fixedly connected to the mounting shell 9 by the engagement of the elastic hook and the card slot 16. When the current of the cable 1 is too large, the automobile fuse 11 inserted in the slot 10 is melted, which plays an overcurrent protection role. When repairing the automobile emergency start battery line, it is only necessary to apply an upward force to the protective cover 13 to make the elastic hook 12 separate from the card slot 16 of the mounting shell 9, so as to realize the removal of the protective cover 13, replace the automobile fuse 11, and then install the protective cover 13 on the mounting shell 9.

[0046] Although the above describes the specific implementation methods of the utility model in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
