Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, specifically to an automotive battery testing instrument. Background Technology

[0002] Automotive battery testers can accurately measure the actual cold-start current of a vehicle's starter battery, the battery's health status, and common faults. This helps repair personnel quickly and accurately identify problems, enabling rapid vehicle repair.

[0003] Existing car battery testers typically consist of a handheld device, a cable, and two alligator clips. The cable length is unstable, causing it and the alligator clips to wobble during transport. Operators need to wrap the cable and clips around the handheld device, but this presents several problems: First, the wrapped cable and clips can easily press the control buttons or scratch the display screen. Pressing the control buttons may lead to accidental activation of the test, and scratches on the display screen not only affect its appearance but, if numerous and deep, can even impair the display content. Second, there is no limit to the number of loops after wrapping, requiring operators to tie the alligator clips around the wrapped cable, making the wrapping and subsequent disassembly operations cumbersome. Furthermore, the alligator clips can easily scratch the cable, display screen, or the handheld device's casing when passing through the gaps in the wrapped cable. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide an automotive battery tester to solve the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automotive battery tester, comprising a tester body and an insulating alligator clip, wherein a handle is connected to the bottom of the tester body, and a winding groove is formed on the outer ring of the handle; a bracket is connected to the back of the tester body, and elastic clips are connected to both sides of the bottom of the bracket; through holes are formed on both sides of the bracket; and a magnetic suction plate is connected to the back of the bracket through a ferrite magnetic shielding plate, and a limit ring is connected to the outer ring of the insulating alligator clip.

[0006] By adopting the above technical solution, during testing, the magnetic plate can be attached to iron or steel structures such as the vehicle's hood and frame, eliminating the need for the operator to hold it constantly. This frees up the operator's hands for other operations. For example, after attaching the car battery tester to the vehicle using the magnetic plate, the operator can use both hands to operate the two insulated alligator clips to simultaneously clamp the positive and negative terminals of the car battery. Alternatively, the operator can simultaneously use other testers to inspect the car battery or other car components, making it convenient to use. If the operator prefers to hold it by hand, the through-hole design allows fingers to pass through the bracket and grip the tester body, avoiding the problem of the bracket increasing the thickness of the tester and making it difficult to hold. For staff whose fingers are too thick to pass through the through-hole, the handle is integrated with the winding groove, allowing for both cable winding and gripping while minimizing space usage. The 40mm wide bracket increases the distance between the magnetic plate and the internal circuitry and components of the instrument, and the ferrite magnetic shield between the magnetic plate and the bracket effectively prevents interference from the magnetic field. After testing, the cable can be wound around the outer ring of the winding groove and inserted into the elastic clip to reduce cable loosening. The magnetic plate then holds the limiting ring in place to prevent the alligator clip from swaying during transport.

[0007] Furthermore, the width between the outer surface of the bracket and the back of the bracket is forty millimeters, and the width between the outer surface of the through hole and the back of the through hole is twenty-five millimeters.

[0008] By adopting the above technical solution, the width of the bracket is 40 mm, which increases the distance between the magnetic plate and the internal circuits and components of the detector body, reducing the interference of the magnetic field of the magnetic plate on the internal circuits and components of the detector body. The width of the through hole is larger than the width of most adults' fingers, so that except for some obese people, they can hold the detector body by passing their fingers through the through hole.

[0009] Furthermore, the magnetic plate is fixedly connected to the ferrite magnetic shielding plate by means of epoxy resin adhesive, and the ferrite magnetic shielding plate is fixedly connected to the bracket by means of epoxy resin adhesive.

[0010] By adopting the above technical solution, the magnetic plate and the ferrite magnetic shield are fixed with epoxy resin, which is simple to produce and has low cost, and the connection is stable and not easy to fall off.

[0011] Furthermore, the surface of the insulating alligator clip is provided with an insulating sleeve, and the insulating sleeve is made of silicone rubber.

[0012] By adopting the above technical solution, the silicone rubber has insulation properties, which can prevent electric shock when the staff operates the insulated alligator clip, and it is convenient to fix the limiting ring through the silicone rubber adhesive to prevent the limiting ring from falling off.

[0013] Furthermore, the limiting ring is made of galvanized steel material, and the limiting ring is adhesively fixed to the insulation skin on the insulated alligator clip through the silicone rubber adhesive.

[0014] By adopting the above technical solution, the limiting ring is made of galvanized steel material, which has low cost and oxidation corrosion resistance, and can be adsorbed and limited by the magnetic attraction plate. The limiting ring is adhered to the insulation skin of the insulated alligator clip. One is to prevent the current from conducting to the limiting ring, and the other is that it will not damage the insulation skin compared with crimping.

[0015] Furthermore, a display screen is installed above the outer surface of the detector body, multiple control buttons are installed below the outer surface of the detector body, a USB interface is installed on one side of the detector body, a cable is installed below the back of the detector body, and insulated alligator clips are connected to both sides of the back of the cable.

[0016] By adopting the above technical solution, the staff can clamp the two insulated alligator clips to the positive and negative poles of the car battery respectively, and then the staff can turn on and control the detector body through the control buttons, so as to measure the voltage, CCA, electronic resistance, rated CCA, charging value, health value, etc. of the car battery. The detected data is directly displayed on the display screen, and the staff can connect the USB interface to the printer through the USB data cable to print the detected battery data into a paper document.

[0017] Furthermore, the cable is detachably connected to the elastic clip.

[0018] By adopting the above technical solution, the staff can wind the cable around the outer circle of the winding groove and then insert the cable into the elastic clip to reduce the occurrence of cable loosening.

[0019] Furthermore, the cross-section of the handle is in a "convex" shape.

[0020] By adopting the above technical solution, the larger diameter at the bottom of the handle can limit the wound cable to prevent the wound cable from spreading downward and improve the winding stability.

[0021] Furthermore, a first sheath is fixed inside the through hole through the silicone rubber adhesive, and the material of the first sheath is silicone rubber.

[0022] By adopting the above technical solution, the silicone rubber is soft in texture, which can prevent the bracket from scratching and improve comfort. At the same time, the silicone rubber has a large friction force, reducing the chance of slipping off.

[0023] In summary, the main beneficial effects of the present utility model are as follows:

[0024] 1. This utility model, through the design of a limiting ring, magnetic plate, winding groove, and elastic clip, allows the cable to be wound around the outer ring of the winding groove when not in use. The cable is then inserted into the elastic clip, and the limiting ring is held in place by the magnetic plate, preventing the cable and alligator clip from moving freely during transport. Furthermore, the magnetic plate can be attached to iron or steel structures such as vehicle hoods and frames during use, eliminating the need for the operator to hold the device constantly. This frees up the operator's hands for other operations; for example, after attaching the car battery tester to the vehicle using the magnetic plate, the operator can easily perform other tasks. Two insulated alligator clips can be operated with one hand to simultaneously clamp onto the positive and negative terminals of a car battery, or the operator can use other testing instruments to inspect the car battery or other car parts at the same time, making it convenient to use. Compared to existing technology where the cable is wound around the testing instrument and knotted, there is a dedicated area to accommodate the cable and limit the insulated alligator clips, preventing the control buttons from being pressed down or the display screen from being scratched. Also, compared to winding the cable and then inserting and knotting the insulated alligator clips, the elastic clips hold the cable near the end area and limit the insulated alligator clips with magnetic attraction, making operation simpler and more convenient. It is also easy to carry and use.

[0025] 2. This utility model increases the distance between the magnetic plate and the internal circuits and components of the detector by setting up a bracket and a ferrite magnetic shield. The bracket is 40 mm wide, which increases the distance between the magnetic plate and the internal circuits and components of the detector. The magnetic plate and the bracket are shielded by the ferrite magnetic shield, which effectively prevents the magnetic field of the magnetic plate from interfering with the internal circuits and components of the detector and increases the stability of the structure.

[0026] 3. This utility model features a handle and a through hole. The through hole allows the operator's fingers to pass through the bracket and grip the main body of the detector, avoiding the problem of the bracket increasing the thickness of the detector and making it difficult to grip. If the operator's fingers are too thick to pass through the through hole, they can grip the main body of the detector through the handle. The handle and the winding groove are integrated into one structure, which can be used to wind the cable and hold it, reducing space occupation and making it convenient to use.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A car battery tester, such as Figure 1 , Figure 2 and Figure 4As shown in the figure, it includes a detector main body 1 and an insulating alligator clip 6. A handle 12 is connected to the bottom of the detector main body 1. The cross-section of the handle 12 is in a "convex" shape. A wire winding groove 13 is provided on the outer circle of the handle 12. If the fingers of the staff are too thick to pass through the through hole 9, the staff can hold the detector main body 1 through the handle 12. The handle 12 and the wire winding groove 13 are of an integral structure, which can both wind the cable 5 and be held, reducing the occupied space; A bracket 8 is connected to the back of the detector main body 1. The width between the outer surface and the back of the bracket 8 is forty millimeters. Since the width of the bracket 8 is forty millimeters, the distance between the magnetic attraction plate 11 and the internal circuits and components of the detector main body 1 is increased, and the magnetic attraction plate 11 and the bracket 8 are shielded by a ferrite magnetic isolation plate 10, effectively preventing the magnetic field of the magnetic attraction plate 11 from interfering with the internal circuits and components of the detector main body 1; Elastic clips 14 are connected to both sides of the bottom of the bracket 8. The bracket 8 and the elastic clips 14 are both made of elastic ABS material toughened by TPE. And U-shaped metal spring pieces can be pre-embedded during injection molding or embedded in the elastic clip 14 by subsequent drilling and grooving and then fastened by bolts to further improve the elasticity. The cable 5 is detachably connected to the elastic clip 14. The staff can wind the cable 5 around the outer circle of the wire winding groove 13 and then insert the cable 5 into the elastic clip 14 to reduce the occurrence of cable 5 loosening; Through holes 9 are provided on both sides of the bracket 8. The width between the outer surface and the back of the through hole 9 is twenty-five millimeters. Through the setting of the through holes 9, it is convenient for the fingers of the staff to pass through the bracket 8 to hold the detector main body 1, avoiding the phenomenon that it is difficult to hold due to the increase in the thickness of the detector caused by the setting of the bracket 8; A magnetic attraction plate 11 is connected to the back of the bracket 8 through a ferrite magnetic isolation plate 10. The magnetic attraction plate 11 is a neodymium iron boron magnet or a ferrite magnet, and the remanent magnetic strength is not less than 0.5T. And the surface of the magnetic attraction plate 11 is provided with anti-slip lines. The magnetic attraction plate 11 is fixedly connected to the ferrite magnetic isolation plate 10 by bonding with epoxy resin adhesive. The ferrite magnetic isolation plate 10 is fixedly connected to the bracket 8 by bonding with epoxy resin adhesive. A limiting ring 7 is connected to the outer circle of the insulating alligator clip 6. The limiting ring 7 is made of galvanized steel material. After the surface of the limiting ring 7 is roughened, it is bonded and fixed to the insulating skin on the insulating alligator clip 6 through silicone rubber adhesive. The surface of the insulating skin can be optionally roughened. The limiting ring 7 is attracted by the magnetic attraction plate 11 to limit the insulating alligator clip 6, avoiding the random shaking of the cable 5 and the insulating alligator clip 6 during the carrying process. And the magnetic attraction plate 11 can be adsorbed on iron, steel structures such as the vehicle hood and frame during use, without the staff always holding it during the detection process.

[0036] Refer to Figures 1-3In the above embodiment, a display screen 2 is installed on the upper surface of the outer surface of the detector body 1, and multiple control buttons 3 are installed on the lower surface of the outer surface of the detector body 1. A USB interface 4 is installed on one side of the detector body 1, and a cable 5 with a length of one meter is installed on the lower back of the detector body 1. Insulating alligator clips 6 are connected to both sides of the back of the cable 5. The surface of the insulating alligator clips 6 is provided with an insulating sleeve made of silicone rubber. The operator clamps the two insulating alligator clips 6 to the positive and negative terminals of the car battery respectively. Then, the operator can turn on and control the detector body 1 through the control button 3, so as to directly display the data of the car battery voltage, CCA, electronic resistance, rated CCA, charge value, health value, etc. on the display screen 2. The operator can also connect the USB interface 4 to a printer through the USB data cable to print the tested battery data into a paper document.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are made to facilitate gripping.

[0039] See Figure 1 and Figure 2 In the above embodiment, a first sheath 15 is fixed inside the through hole 9 by a silicone rubber adhesive. The first sheath 15 is made of silicone rubber. The first sheath 15 is designed to prevent workers' fingers from being scratched when they pass through the through hole 9, and it also provides greater friction to prevent slipping and is soft and comfortable.

[0040] The implementation principle of this utility model is as follows: First, when needed, the operator removes the insulated alligator clip 6 from the back of the magnetic suction plate 11, pulls the cable 5 out of the elastic clip 14, and releases the cable 5 from the winding groove 13; the operator clamps the two insulated alligator clips 6 onto the positive and negative terminals of the car battery respectively, and then the operator can turn on and control the main body 1 of the detector through the control button 3, so that the voltage, CCA, electronic resistance, rated CCA, charging value, health value, etc. of the car battery are directly displayed on the display screen 2, and the operator can connect the USB interface 4 to the printer through the USB data cable to print the detected battery data into a paper document;

[0041] During testing, the magnetic plate 11 can be attached to iron or steel structures such as the vehicle's hood and frame, eliminating the need for the operator to hold it constantly. This frees up the operator's hands for other operations. For example, after attaching the car battery tester to the vehicle using the magnetic plate 11, the operator can use both hands to operate the two insulated alligator clips 6 to simultaneously clamp the positive and negative terminals of the car battery. Alternatively, the operator can use other testers to inspect the car battery or other car components simultaneously, making it convenient to use. If the operator prefers to hold it by hand, the through-hole 9 allows the operator's fingers to pass through the bracket 8 and grip the tester body 1, avoiding the problem of the bracket 8 increasing the thickness of the tester and making it difficult to hold. If the operator's fingers are too thick to pass through the through-hole 9, the operator can grip the tester body 1 using the handle 12. The handle 12 is an integrated structure with the cable winding groove 13, which can be used to wind the cable 5 and hold the device, reducing space occupation. Furthermore, the first protective sleeve 15 prevents the operator's fingers from being scratched when passing through the through-hole 9, provides greater friction to prevent slippage, and is soft and comfortable.

[0042] Because the width of the bracket 8 is 40 mm, the distance between the magnetic plate 11 and the internal circuit and components of the detector body 1 is increased, and the magnetic plate 11 and the bracket 8 are shielded by the ferrite magnetic shielding plate 10, which effectively avoids the magnetic field of the magnetic plate 11 from interfering with the internal circuit and components of the detector body 1.

[0043] After the inspection is completed, the staff can wind the cable 5 around the outer ring of the winding groove 13 and then insert the cable 5 into the elastic clip 14 to reduce the occurrence of cable 5 loosening. Then, the magnetic suction plate 11 will hold the limiting ring 7 to limit the insulating alligator clip 6 and prevent the cable 5 and the insulating alligator clip 6 from shaking randomly during the carrying process.
