[0026] Embodiment 1

[0027] Referring to Figure 1 and Figure 2 , it is the first embodiment of the present utility model. This embodiment provides an automotive battery internal resistance tester, which includes a main body assembly 100 and a storage assembly 200. The two cooperate to neatly store the wires, avoid the wires from being wound around each other, prevent the wires from rubbing against other objects during use and causing damage to the outer skin, and extend the service life of the wires.

[0028] Specifically, the main body component 100 includes a tester body 101, a wire 102, and a probe clip 103. One end of the wire 102 is fixed to the top of the tester body 101, and the other end is fixed to the bottom of the probe clip 103.

[0029] Check the wire 102 and the probe clip 103, then accurately connect the positive and negative poles of the probe clip 103 to the positive and negative poles of the car battery respectively, and start the tester body 101 to start detecting the car battery.

[0030] Specifically, the storage component 200 is arranged on the top of the tester body 101 and includes a protective cover 201, a storage member 202, a magnet 203, a folding member 204, and a limiting member 205. The protective cover 201 is sleeved on the surface of the tester body 101, the storage member 202 is located on the top of the protective cover 201, the magnet 203 is fixed to one side of the protective cover 201, one end of the folding member 204 is rotatably connected to the top of the protective cover 201, and the other end is rotatably connected to the bottom of the storage member 202. The limiting member 205 is fixed to one side of the protective cover 201.

[0031] The protective cover 201 sleeved on the surface of the tester body 101 plays a protective role. At this time, by releasing the limitation of the limiting member 205 on the storage member 202, the folding member 204 can fold the storage member 202 to the top of the protective cover 201 and fix it by the adsorption of the magnet 203. At this time, the probe clip 103 can be taken out, the wire 102 can be pulled out and connected to the car battery, and then the tester body 101 is started to start the test work.

[0032] Embodiment 2

[0033] Refer to Figures 2 to 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0034] Specifically, there are two groups of magnets 203, and each group has two, and they are symmetrically fixed in the protective cover 201 and the storage member 202 respectively.

[0035] When the storage member 202 is folded to the top of the protective cover 201, the magnets 203 arranged inside the two will adsorb to limit the storage member 202 and prevent the storage member 202 from being folded back. After being limited, the subsequent work of detecting the car battery can be carried out.

[0036] Specifically, the storage member 202 includes a storage rack 202a, a retractable spring 202b, a limiting post 202c, and a rotating plate 202d. The storage rack 202a is located on the top of the protective cover 201, the retractable spring 202b is arranged in the storage rack 202a, the limiting post 202c is fixed in the storage rack 202a, and the rotating plate 202d is rotatably connected to the top of the limiting post 202c.

[0037] The limit stake 202c is provided with a slot, one end of the retractable spring 202b is inserted into the slot, the rotating plate 202d is provided with a socket, one end of the retractable spring 202b has a protrusion and is connected to the socket. When the rotating plate 202d rotates, the retractable spring 202b will be driven to move. The wire 102 is placed on the rotating plate 202d. When the storage rack 202a is folded to the top of the protective cover 201, the wire 102 can be pulled outwards. At this time, the rotating plate 202d will be rotated, and the retractable spring 202b will be deformed by force. When the wire 102 is recycled, the retractable spring 202b will be reset, and at this time, the rotating plate 202d will be rotated in the reverse direction, and then the wire 102 will be recycled.

[0038] Specifically, a slot 202a-1 is provided in the storage rack 202a.

[0039] When the tester body 101 is not in use, the probe clip 103 can be stored in the slot 202a-1 to prevent the probe clip 103 from being damaged due to exposure. At the same time, it is also convenient to carry the tester body 101 after the probe clip 103 is stored.

[0040] Specifically, the storage member 202 further includes a fixing stake 202e and a limit frame 202f. The fixing stake 202e is fixed to the top of the rotating plate 202d, and the limit frame 202f is fixed to the surface of the fixing stake 202e.

[0041] One end of the wire 102 is arranged in the fixing stake 202e. When the wire 102 is pulled, the fixing stake 202e will be rotated by force. At this time, the rotating plate 202d will be rotated by force. When the rotating plate 202d rotates, the retractable spring 202b will be deformed by force. After the wire 102 is pulled out to an appropriate position, the tester body 101 can be turned on to test the car battery. After the test is completed, the retractable spring 202b will be reset, and at this time, it will drive the rotating plate 202d to rotate in the reverse direction. The rotating plate 202d will drive the fixing stake 202e to rotate in the reverse direction. At this time, the fixing stake 202e will retract the wire 102, and the limit frame 202f will prevent the wire 102 from being wound or knotted due to too fast speed during recycling.

[0042] Specifically, the folding member 204 includes a fixing frame 204a, a fixing rod 204b and an adjusting plate 204c. The fixing frame 204a is fixed to the top of the protective cover 201, the fixing rod 204b is fixed in the fixing frame 204a, and the adjusting plate 204c is sleeved on the surface of the fixing rod 204b.

[0043] There are two fixing frames 204a, which are respectively installed at the top of the protective cover 201 and the bottom of the storage rack 202a. There are also two fixing rods 204b, which are respectively fixed inside the fixing frames 204a. The two ends are sleeved on the surfaces of the two fixing rods 204b through the adjusting plate 204c to connect them. At this time, the storage rack 202a can be folded, and the storage rack 202a is folded to the top of the protective cover 201 for subsequent work.

[0044] Embodiment 3

[0045] Refer to Figure 5 , which is the third embodiment of the present utility model. This embodiment is based on the first two embodiments.

[0046] Specifically, the limiting member 205 includes a pushing block 205a, a limiting frame 205b, a first spring 205c, a moving block 205d, a second spring 205e, and a limiting block 205f. The pushing block 205a is fixed to one side of the storage rack 202a, the limiting frame 205b is fixed to one side of the protective cover 201, one end of the first spring 205c is fixed inside the limiting frame 205b, and the other end is fixed to one side of the moving block 205d. One end of the second spring 205e is fixed to one side of the moving block 205d, and the other end is fixed to one side of the limiting block 205f.

[0047] A sliding groove is formed in the moving block 205d. A protrusion is provided on one side of the limiting frame 205b and is slidably connected to the sliding groove. When the storage rack 202a is folded, the pushing block 205a will move towards the limiting frame 205b, then contact the limiting block 205f and push the limiting block 205f to move to one side. At this time, the second spring 205e is deformed by force. When the pushing block 205a is separated from the limiting block 205f and the pushing block 205a enters the limiting frame 205b, the restoring elastic force of the second spring 205e will push out the limiting block 205f and limit the pushing block 205a to prevent the storage rack 202a from being folded back. When the limit is released, the moving block 205d is moved downward. At this time, the first spring 205c is deformed by force, and at the same time, the limiting block 205f will also move downward to separate from the pushing block 205a. Then the storage rack 202a can be folded to the top of the protective cover 201. Then the moving block 205d is released, and the restoring elastic force of the first spring 205c will pull the moving block 205d back to complete the reset. At this time, subsequent operations can be performed.

[0048] Specifically, one end of the pushing block 205a is a slope, and the slope angle is 45 degrees.

[0049] When the storage rack 202a is folded, the slope of the pushing block 205a will contact the limiting block 205f and push the moving block 205d to move to one side. When the pushing block 205a is combined with the limiting frame 205b, the limiting block 205f will limit the pushing block 205a to prevent the storage rack 202a from being folded back.

[0050] In use, first move the moving block 205d downward. Then, the first spring 205c deforms under force. At the same time, the limiting block 205f also moves downward and separates from the pushing block 205a. At this time, the storage rack 202a can be folded to the top of the protective cover 201. Then, release the moving block 205d. The restoring elastic force of the first spring 205c will pull the moving block 205d and the limiting block 205f back to complete the reset. Next, when the storage rack 202a is folded to the top of the protective cover 201, the magnets 203 provided inside the two will adsorb to limit the storage rack 202a. Then, take out the probe clip 103 from the slot 202a-1 and pull the wire 102 outward. Then, the fixing post 202e will rotate under force and drive the rotating plate 202d to rotate under force. While the rotating plate 202d is rotating, the retractable spring 202b deforms under force. At this time, connect the positive and negative poles of the probe clip 103 to the positive and negative poles of the car battery respectively, and start the tester body 101 to start detecting the car battery.

[0051] After use, separate the probe clip 103 from the car battery. At this time, the retractable spring 202b will reset, and then drive the rotating plate 202d to rotate in the reverse direction. The rotating plate 202d will drive the fixing post 202e to rotate in the reverse direction. Then, the fixing post 202e will retract the wire 102. The limiting frame 202f will prevent the wire 102 from being wound or knotted due to too fast speed during the recovery. After the recovery is completed, fold the storage rack 202a. The pushing block 205a will move towards the limiting frame 205b. Then, the inclined surface of the pushing block 205a will contact the limiting block 205f and push the moving block 205d to move to one side. At this time, the second spring 205e deforms under force. When the pushing block 205a is combined with the limiting frame 205b, the restoring elastic force of the second spring 205e will push out the limiting block 205f and limit the pushing block 205a to prevent the storage rack 202a from folding in the reverse direction. At this time, the storage work of the wire 102 is completed.
