Description

Technical Field

[0001] The present invention relates to the field of protection of a resistance performance testing machine, and in particular to a protection structure for a resistance performance testing machine. Background Art

[0002] Insulation impedance monitoring is a key component in ensuring the safety and stability of new energy vehicle electrical systems. Using insulation impedance monitoring instruments, accurate insulation data can be obtained from the electrical system, thereby evaluating the system's insulation performance. However, if the tester is damaged during vehicle insulation performance testing, the accuracy of the test results will be directly affected, leading to misleading evaluations of vehicle products. Therefore, protecting the tester is an important prerequisite for ensuring the accuracy of test results. However, existing protection structures still have the following defects:

[0003] (1) When protecting the resistance performance tester, the existing protective device generally directly fixes the resistance performance tester to the inside of the protective device through multiple bolts. During installation, the bolts need to be tightened one by one, which is very troublesome.

[0004] (2) When the existing protective device is in use, if the resistance performance tester needs to be repaired, it is inconvenient to disassemble the resistance performance tester, and the practicality is low.

[0005] (3) When the resistance performance tester is located inside the protective device, the protective device lacks the heat dissipation function, which in turn affects the working efficiency of the resistance performance tester.

[0006] Therefore, a protective structure for a resistance performance testing machine is proposed. Summary of the Invention

[0007] The purpose of the present invention is to provide a protective structure for an impedance performance tester in view of the defects of the prior art, so as to solve the problems raised by the above background technology.

[0008] To achieve the above-mentioned object of the invention, the present invention provides the following technical solutions: a protective structure for a resistance performance tester, comprising a resistance performance tester body, a protective mechanism provided on the outside of the resistance performance tester body for protecting and fixing the resistance performance tester body, a removal assembly provided below the protective mechanism for removing the resistance performance tester body fixed in the protective mechanism from the protective mechanism, and a ventilation assembly provided on the protective mechanism for dissipating heat from the resistance performance tester;

[0009] The protective mechanism includes a protective shell, a bottom plate, a support plate, a vertical plate, a sliding rod, an annular groove, a spring and a limiting hole. The protective shell is arranged on the outside of the resistance performance testing machine body, the bottom plate is bolted to the bottom of the resistance performance testing machine body and is located inside the protective shell, the two support plates are respectively arranged on the bottom of the bottom plate, the two vertical plates are respectively arranged on the inner bottom wall of the protective shell, the two sliding rods are slidably connected to the inside of the vertical plate, the annular groove is opened on the outer wall of the sliding rod, the two springs are respectively mounted on the outside of the two sliding rods, and the two limiting holes are respectively opened on the two support plates.

[0010] As a preferred technical solution of the present invention, the picking assembly includes a connecting rope, a circular plate, a connecting rod, a rotating plate and a cross knob. The two connecting ropes are respectively fixedly connected to the side walls of the two sliding rods, the circular plate is fixedly connected to one end of the two connecting ropes, the connecting rod is coaxially arranged at the bottom of the circular plate, the rotating plate is rotatably connected to the bottom of the protective shell, and the cross knob is fixed to the bottom of the rotating plate.

[0011] As a preferred technical solution of the present invention, the ventilation assembly includes a heat dissipation air box and a filter. The heat dissipation air box is installed at the bottom of the protective shell, the filter is arranged at the bottom of the heat dissipation air box, a heat dissipation fan is installed inside the heat dissipation air box, and the heat dissipation air box is connected to the protective shell.

[0012] As a preferred technical solution of the present invention, a protective pad is provided on the outside of the resistance performance tester body, and the outer wall of the protective pad is tightly fitted with the inner wall of the protective shell.

[0013] As a preferred technical solution of the present invention, four supporting legs are fixedly connected to the bottom of the protective shell, and the four supporting legs are respectively located at the four corners of the protective shell, and the height of the supporting legs is greater than the height of the heat dissipation fan chassis.

[0014] As a preferred technical solution of the present invention, a protective cover is hinged on the top side wall of the protective shell, and the length and width of the protective cover are the same as those of the protective shell.

[0015] As a preferred technical solution of the present invention, two opposite side walls of the protective shell are fixedly connected with a transport portion.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention provides a protective mechanism, which allows the resistance performance tester body and the bottom plate to directly enter the protective shell vertically from top to bottom when in use. Then the support plate contacts the slide rod, causing the slide rod to move to one side. When the bottom of the support plate contacts the bottom wall of the protective shell, the slide rod will be sent into the limiting hole by the elastic force of the spring, thereby fixing the resistance performance tester body. At this time, the protective shell can provide protection for the resistance performance tester body. At the same time, this fixing method does not use bolt installation, which is convenient and fast.

[0018] 2. The present invention provides a taking component. When the resistance performance tester body needs to be disassembled, an external screwdriver is inserted into the cross knob, and the circular plate is rotated accordingly, so that the connecting rope is wrapped around the circular plate. At this time, the sliding rod will move away from the limiting hole, and the support plate will lose its restriction. Then, the resistance performance tester body can be taken out from the inside of the resistance performance tester body.

[0019] 3. The present invention provides a ventilation component. When the resistance performance tester body operates for a long time, heat will be generated. At this time, the heat is discharged to the outside through the heat dissipation fan box, avoiding heat accumulation between the bottom plate and the bottom wall of the resistance performance tester body, which will affect the normal operation of the resistance performance tester body.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0032] like Figure 1-7 As shown, this embodiment provides a protective structure for a resistance performance tester, including a resistance performance tester body 1. A protective mechanism 2 is provided on the outside of the resistance performance tester body 1 for protecting and fixing the resistance performance tester body 1. A removal assembly 3 is provided below the protective mechanism 2 for removing the resistance performance tester body 1 fixed in the protective mechanism 2 from the protective mechanism 2. A ventilation assembly 4 is provided on the protective mechanism 2 for dissipating heat from the resistance performance tester.

[0033] like Figure 4 and Figure 6As shown, the protective mechanism 2 includes a protective shell 201, a bottom plate 202, a support plate 203, a vertical plate 204, a slide bar 205, an annular groove 206, a spring 207 and a limiting hole 208. The protective shell 201 is arranged on the outside of the resistance performance tester body 1, the bottom plate 202 is bolted to the bottom of the resistance performance tester body 1, and is located inside the protective shell 201, the two support plates 203 are respectively arranged on the bottom of the bottom plate 202, the two vertical plates 204 are respectively arranged on the inner bottom wall of the protective shell 201, the two slide bars 205 are slidably connected to the inside of the vertical plate 204, the annular groove 206 is opened on the outer wall of the slide bar 205, the two springs 207 are respectively sleeved on the outside of the two slide bars 205, the two limiting holes 208 are respectively opened on the two support plates 203, the bottom plate 202 is slidably connected to the protective shell 201, and the two ends of the spring 207 are respectively connected to the outside of the two slide bars 205. The ends are fixedly connected to the side walls of the annular groove 206 and the side walls of the vertical plate 204 respectively. The bottom end of the support plate 203 is triangular, and the end of the slide rod 205 close to the support plate 203 is arc-shaped. The slide rod 205 is slidably connected to the limiting hole 208. When in use, pick up the resistance performance tester body 1 and the bottom plate 202, so that the resistance performance tester body 1 enters the resistance performance tester body 1 from top to bottom, and then the support plate 203 will contact one end of the slide rod 205. At this time, the slide rod 205 will move to the side away from the support plate 203. At this time, the spring 207 contracts. When the bottom of the support plate 203 contacts the inner bottom wall of the protective shell 201, the elastic force of the spring 207 will cause the slide rod 205 to enter the interior of the limiting hole 208. At this time, the resistance performance tester body 1 will be fixed, and the protective shell 201 plays a protective role for the resistance performance tester body 1.

[0034] like Figure 6 and Figure 7As shown, the picking assembly 3 includes a connecting rope 301, a circular plate 302, a connecting rod 303, a rotating plate 304 and a cross knob 305. The two connecting ropes 301 are respectively fixedly connected to the side walls of the two sliding rods 205, the circular plate 302 is fixedly connected to one end of the two connecting ropes 301, the connecting rod 303 is coaxially arranged at the bottom of the circular plate 302, the rotating plate 304 is rotatably connected to the bottom of the protective shell 201, the cross knob 305 is fixed to the bottom of the rotating plate 304, the connecting rope 301 is located on the end of the sliding rod 205 away from the support plate 203, the circular plate 302 is fixedly connected to the connecting rod 303, and the connecting rod 303 is fixedly connected. The bottom of 03 passes through the bottom of the resistance performance tester body 1 and is fixedly connected to the top of the rotating plate 304. The connecting rod 303 is rotatably connected to the resistance performance tester body 1. When the resistance performance tester body 1 needs to be disassembled, the cross knob 305 is rotated. At this time, the rotating plate 304, the connecting rod 303 and the circular plate 302 will rotate, and then the connecting rope 301 will be wrapped around the circular plate 302. At this time, the slide rod 205 will gradually disengage from the limiting hole 208. When the slide rod 205 is completely disengaged from the limiting hole 208, the resistance performance tester body 1 can be lifted up, and then the resistance performance tester body 1 can be taken out.

[0035] like Figure 5 As shown, the ventilation component 4 includes a heat dissipation air box 401 and a filter 402. The heat dissipation air box 401 is installed at the bottom of the protective shell 201, and the filter 402 is arranged at the bottom of the heat dissipation air box 401. A heat dissipation fan is installed inside the heat dissipation air box 401. The heat dissipation air box 401 is connected to the protective shell 201. When the resistance performance tester body 1 operates for a long time, heat will be generated. At this time, the heat will be discharged to the outside of the resistance performance tester body 1 through the heat dissipation air box 401 to avoid heat accumulation. The filter 402 can effectively prevent external dust from entering the inside of the protective shell 201.

[0036] like Figure 1 As shown, a protective pad 5 is provided on the outside of the resistance performance tester body 1, and the outer wall of the protective pad 5 is tightly fitted with the inner wall of the protective shell 201. When in use, the protective pad 5 can provide protection for the outer wall of the resistance performance tester body 1, thereby improving the protective effect of the resistance performance tester body 1.

[0037] like Figure 5 As shown, four supporting legs 6 are fixedly connected to the bottom of the protective shell 201. The four supporting legs 6 are respectively located at the four corners of the protective shell 201. When in use, the four supporting legs 6 can prevent the bottom of the protective shell 201 from directly contacting the ground, causing wear on the bottom of the protective shell 201. The height of the supporting legs 6 is greater than the height of the heat dissipation fan chassis 401 and the cross knob 305.

[0038] like Figure 1As shown, a protective cover 7 is hinged on the top side wall of the protective shell 201. The length and width of the protective cover 7 are the same as those of the protective shell 201. When the use of the resistance performance tester body 1 is completed, the protective cover 7 can be rotated to prevent external debris from contacting the resistance performance tester body 1.

[0039] like Figure 1 As shown, the two opposite side walls of the protective shell 201 are fixedly connected with a transport part 8. When the resistance performance tester body 1 and the protective shell 201 need to be moved, the user can place both hands on both sides of the two transport parts 8, and then insert the fingers of both hands into the interior of the transport part 8 to facilitate the movement of the resistance performance tester body 1.

[0040] Specifically, when the protective structure of the resistance performance tester is used: pick up the resistance performance tester body 1 and the bottom plate 202, and make the resistance performance tester body 1 enter the resistance performance tester body 1 from top to bottom, then the support plate 203 will contact one end of the slide bar 205, at this time the slide bar 205 will move to the side away from the support plate 203, at this time the spring 207 will contract, when the bottom of the support plate 203 contacts the inner bottom wall of the protective shell 201, the elastic force of the spring 207 will make the slide bar 205 enter the inside of the limiting hole 208, at this time the resistance performance tester body 1 will be fixed, and the protective shell 201 plays a protective role for the resistance performance tester body 1. When it is necessary to disassemble When the resistance performance tester body 1 is in operation, by rotating the cross knob 305, the rotating plate 304, the connecting rod 303 and the circular plate 302 will rotate, and then the connecting rope 301 will be wrapped around the circular plate 302. At this time, the slide bar 205 will gradually disengage from the limiting hole 208. When the slide bar 205 is completely out of the limiting hole 208, the resistance performance tester body 1 can be lifted up, and then the resistance performance tester body 1 can be taken out. When the resistance performance tester body 1 operates for a long time, heat will be generated. At this time, the heat will be discharged to the outside of the resistance performance tester body 1 through the heat dissipation fan chassis 401 to avoid heat accumulation. The filter 402 can effectively prevent external dust from entering the inside of the protective shell 201.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
