Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0056] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0057] See also Figure 1-Figure 12 A new energy vehicle battery pack detection device provided by an embodiment of the present invention includes a detection support 1, on which a fixed platform 2 is fixedly mounted, and further includes:

[0058] A movable enclosure plate 1 8 and a movable enclosure plate 2 9, wherein the movable enclosure plate 1 8 and the movable enclosure plate 2 9 are both slidably connected to the detection support 1 through a sliding structure 12, and the movable enclosure plate 1 8 and the movable enclosure plate 2 9 are respectively located on both sides of the fixed platform 2;

[0059] Wherein, the movable enclosure plate 1 8 and the movable enclosure plate 2 9 are respectively fixedly mounted with a side block kit 10 and an enclosure member 11, and the side block kit 10 and the enclosure member 11 are detachably connected;

[0060] and a detection protection mechanism, which is respectively connected to the detection support 1, the movable enclosure plate 1 8 and the movable enclosure plate 2 9, wherein the detection protection mechanism includes a detection drive cylinder 6, a detection mounting seat 34 and a protection drive assembly;

[0061] The protection drive assembly is respectively connected to the detection support 1, the movable enclosure plate 1 8 and the movable enclosure plate 2 9, and a detection drive cylinder 6 is also installed on the protection drive assembly, and a detection mounting seat 34 is installed on the detection drive cylinder 6. The detection mounting seat 34 is located above the fixed platform 2, and a detection device is also installed at the bottom end of the detection mounting seat 34.

[0062] See also Figure 1-Figure 12 , and also includes: a display device 3 and an alarm device 7, wherein the display device 3 and the alarm device 7 are both fixedly connected to the detection support 1 and electrically connected to the detection protection mechanism.

[0063] When testing the battery pack, first, the testing support 1 can be fixed to the ground or other components by bolting (to place the overall testing equipment at a relatively low position, which is convenient for the disassembly and assembly of the battery pack on the one hand, and reduces the probability of injury to the important organs of the upper body of the relevant personnel on the other hand, thereby further ensuring the safety of the testing equipment. In addition, during the testing process, the staff is located on the side facing the movable enclosure plate 8, which is convenient for operation and protection of the staff, which will not be elaborated here), and then, the battery pack to be tested is placed on the fixed platform 2 and fixed. At this time, the protection drive component is started to drive the movable enclosure plate 1 8 and the movable enclosure plate 2 9 to move toward the direction of the battery pack at the same time, and as The movable enclosure plate 1 8 and the movable enclosure plate 2 9 are close to each other, and the side block kit 10 and the enclosure member 11 are changed from the original separated state to the mutually inserted state (when the three surfaces of the battery pack are in a mutually separated state, it is convenient for the battery pack to be installed on the fixed platform 2), until the movable enclosure plate 1 8 and the movable enclosure plate 2 9 are close to the side position of the battery pack, and some parts of the protective drive assembly are also close to the top of the battery pack. At this time, the detection support 1, the movable enclosure plate 1 8, the movable enclosure plate 2 9, the side block kit 10, the enclosure member 11 and the protective drive assembly form a cubic detection space, and the battery pack is located in the detection space on the fixed platform 2, wherein the side block kit 10 and the enclosure member 11 can adopt a cylindrical and columnar structure, and consist of multiple relatively close distances. The side block kit 10 and the enclosure member 11 can also be formed by the cylinders and columns close to each other to block the splashes in the detection space, thereby forming an enclosure protection with gaps to avoid excessive air pressure in the detection space. Of course, the side block kit 10 and the enclosure member 11 can also both adopt a plate-like structure, and the plate-like structure of the side block kit 10 is provided with a square groove, so that when the two are close to each other, the plate-like structure of the enclosure member 11 is inserted into the square groove, thereby forming a relatively closed enclosure protection, which will not be elaborated here. In addition, when certain components of the protective drive assembly move toward the top of the battery pack, the detection drive cylinder 6 and the detection mounting seat 34 will be driven to move downward synchronously. Before detecting the battery pack, the corresponding detection equipment can be installed on the bottom end of the detection mounting seat 34 according to the detection items. After the size of the detection space is appropriate, starting the detection drive cylinder 6 will drive the detection mounting seat 34 and the detection equipment to move downward, and perform detection operations on the battery pack located on the fixed platform 2. At the same time, the size of the detection space can be adaptively adjusted according to the size of the battery pack to be detected, so that as the size of the battery pack changes, the mobile enclosure plate 1 8 and the mobile enclosure plate 2 9 are always at an appropriate distance from the battery pack, thereby ensuring the enclosure protection effect. If the distance is too large, the shock waves and splashes generated during the detection process may not be effectively controlled, thereby increasing the risk of operation. The operation is simple, and for certain dangerous detection items of the battery pack, it can ensure that the equipment can carry out detection work safely, especially for battery packs of different sizes.It can ensure the safety of testing equipment and related personnel, and provide convenience for the staff.

[0064] In one embodiment of the present invention, see Figure 1-Figure 12 , the protection drive component comprises:

[0065] A lifting control device 4, wherein the lifting control device 4 is connected to the detection support 1, and a top enclosure plate 5 is fixedly mounted on the lifting control device 4, and the top enclosure plate 5 is fixedly connected to the detection drive cylinder 6;

[0066] A square baffle frame 13, wherein the square baffle frame 13 is fixedly connected to the top enclosure plate 5;

[0067] A smooth cylinder 15, wherein the number of the smooth cylinders 15 is two, and the two smooth cylinders 15 are respectively fixedly connected to the movable enclosure plate 1 8 and the movable enclosure plate 2 9;

[0068] And a driving chute plate 14, one end of which is fixedly connected to the top enclosure plate 5, wherein the smooth cylinder 15 is clamped on the other end of the driving chute plate 14 and is slidably connected to the driving chute plate 14.

[0069] See also Figure 1-Figure 12 , a lifting driving part 40 is provided in the detection driving cylinder 6, and a lifting circular plate 33 is also slidably installed in the detection driving cylinder 6, and the lifting circular plate 33 is fixedly connected to the detection mounting seat 34;

[0070] The lifting circular plate 33 is also provided with a circuit breaker control component, and the circuit breaker control component is also connected to the detection mounting seat 34 and the lifting driving part 40 respectively.

[0071] The circuit breaker control assembly comprises:

[0072] A junction box 35, wherein the junction box 35 is fixedly mounted on the lifting circular plate 33;

[0073] A telescopic chamber 38, wherein the telescopic chamber 38 is fixedly connected to the detection mounting seat 34 and the lifting drive unit 40, and a telescopic control member 37 is fixedly mounted on the telescopic chamber 38;

[0074] A telescopic crescent plate 36, wherein the telescopic crescent plate 36 is slidably mounted in the telescopic chamber 38;

[0075] And an elastic circuit breaker plate 39 , one end of which is fixedly connected to the junction box 35 , and the other end of which is in contact with the telescopic crescent plate 36 .

[0076] It also includes: a transformer control unit 32 , which is fixedly installed in the detection drive cylinder 6 and is detachably connected to the lifting circular plate 33 , and the transformer control unit 32 is also electrically connected to the telescopic control member 37 .

[0077] After the detection equipment and the battery pack are installed, the lifting control device 4 is started, wherein the lifting control device 4 can be a hydraulically controlled device to adjust the distance between the top enclosure plate 5 and the detection support 1, so as to realize the detection and protection function of the battery pack. When the top enclosure plate 5 moves downward, it can drive the detection drive cylinder 6 and the detection mounting seat 34 to move downward synchronously, and drive the driving inclined slot plate 14 to move downward. At this time, the driving inclined slot plate 14 will push the smooth cylinder 15, and drive the moving enclosure plate 1 8 and the moving enclosure plate 2 9 to slide on the sliding structure 12, wherein the sliding structure 12 can adopt a structure in which a slide rail and a slider cooperate, so as to form a detection space with suitable space size and protective function;

[0078] In addition, during the detection process, such as short-circuit testing or power detection, when the battery pack is in a dangerous situation, it is necessary to promptly cut off the power, otherwise it may cause a greater electrical accident. Therefore, by setting the telescopic control member 37, when encountering a dangerous situation, the telescopic control member 37 is immediately energized and generates magnetism, wherein the telescopic control member 37 can be in the form of an electromagnet, and under the action of the magnetic attraction of the telescopic control member 37, the telescopic crescent plate 36 can be instantly retracted into the telescopic chamber 38, wherein a reset spring can also be provided between the telescopic crescent plate 36 and the telescopic chamber 38 to reset the telescopic control member 37 when the telescopic control member 37 is powered off. When the telescopic crescent plate 36 is in a working state of extending outside the telescopic chamber 38, after the telescopic crescent plate 36 is retracted into the telescopic chamber 38, the elastic circuit breaker plate 39 moves in a direction away from the telescopic crescent plate 36 under the action of elasticity until it is away from the telescopic crescent plate 36. At this time, the safety of the entire circuit can be ensured by the barrier effect of the lifting circular plate 33 and the large distance between the elastic circuit breaker plate 39 and the telescopic crescent plate 36. In addition, by setting the substation control unit 32, wherein the substation control unit 32 can be in the form of a pressure sensor, when the lifting circular plate 33 reaches the substation control unit 3 2, wherein the area corresponding to the substation control unit 32 is a position state where the distance between the mobile enclosure plate 1 8 and the mobile enclosure plate 2 9 is relatively large. Since the size of the battery pack to be detected is relatively large at this time, the probability of danger will also be greater. To further ensure electrical safety, when the sensor arranged in the detection space detects that the battery pack is in danger, the substation control unit 32 will further increase the current flowing into the telescopic control member 37 under the control of the substation control unit 32, thereby correspondingly increasing the magnetic attraction of the telescopic control member 37, which can not only increase the speed of the telescopic crescent plate 36, but also increase the telescopic The crescent plate 36 is retracted into the telescopic chamber 38 to ensure that the telescopic crescent plate 36 and the elastic circuit breaker plate 39 are quickly and completely disengaged, and the distance between the telescopic crescent plate 36 and the elastic circuit breaker plate 39 is increased accordingly, which is beneficial to ensure the safety during the detection process. Before the detection work is carried out, a lifting drive part 40 is set, wherein the lifting drive part 40 can be in the form of a telescopic cylinder. The lifting circular plate 33 is driven downward in the detection drive cylinder 6 by the pushing action of the lifting drive part 40, and the detection equipment on the bottom end of the detection mounting seat 34 performs detection operations on the battery pack below, which will not be elaborated here.

[0079] In one embodiment of the present invention, see Figure 1-Figure 12 , further comprising: a locking notch 16, wherein the locking notch 16 is provided on the enclosure member 11;

[0080] And an anti-slip reinforcement component, wherein the anti-slip reinforcement component is connected to the side stop kit 10 and the locking notch 16 respectively.

[0081] The anti-slip reinforcement component comprises:

[0082] A sliding circular plate 28, wherein the sliding circular plate 28 is slidably mounted in the side stop kit 10, and an auxiliary spring 29 is fixedly mounted on the sliding circular plate 28, and the other end of the auxiliary spring 29 is fixedly connected to the side stop kit 10;

[0083] A buckle elastic plate 27, wherein the buckle elastic plate 27 is fixedly connected to the sliding circular plate 28, and the buckle elastic plate 27 is also detachably connected to the locking notch 16;

[0084] A reset push plate 26, one end of which is fixedly connected to the buckle elastic plate 27;

[0085] And a reset chute cavity 25 , wherein the reset chute cavity 25 is fixedly installed in the side stop kit 10 and is detachably connected to the reset push plate 26 .

[0086] See also Figure 1-Figure 12 , further comprising: a pull rope 2 30, one end of which passes through the auxiliary spring 29 and is fixedly connected to the sliding circular plate 28;

[0087] A confluence integrated box 20, the confluence integrated box 20 is fixedly connected to the movable enclosure plate 8, and a pull rope 19 is arranged in the confluence integrated box 20, the pull rope 19 and the pull rope 2 30 are connected through a displacement buffer 31, and the displacement buffer 31 is fixedly installed in the side baffle kit 10;

[0088] And a synchronous pulling component, which is respectively connected to the movable enclosure plate 8, the pull rope 19 and the protective driving component.

[0089] The synchronous pulling assembly comprises:

[0090] A limit support plate 17, wherein the limit support plate 17 is fixedly mounted on the movable enclosure plate 8, and a guide sleeve 18 is also fixedly mounted on the limit support plate 17, wherein the other end of the pull rope 19 passes through the guide sleeve 18 and the limit support plate 17, and is slidably connected with the guide sleeve 18 and the limit support plate 17;

[0091] A guide magnetic disk 22, wherein the guide magnetic disk 22 is fixedly mounted on the limit support plate 17 and is arranged opposite to the guide sleeve 18, and the pull rope 19 also passes through the guide magnetic disk 22;

[0092] A magnetic seat 23, wherein the magnetic seat 23 is detachably connected to the guide magnetic disk 22 and is fixedly connected to the other end of the pull rope 19, and a linkage pull ring 24 is also fixedly installed on the magnetic seat 23;

[0093] And an L-shaped pulling rod 21, wherein the L-shaped pulling rod 21 is fixedly mounted on the protection driving assembly and is detachably connected to the linkage pulling ring 24.

[0094] During the battery pack inspection process, in order to ensure the safety performance of the inspection process, through the provided locking notch 16, when the enclosure 11 enters the side block kit 10, the locking notch 16 will enter the side block kit 10, and when the enclosure 11 contacts the sliding circular plate 28 and pushes the sliding circular plate 28 to move in the side block kit 10, the sliding circular plate 28 will pull the buckle elastic plate 27 and the reset push plate 26 to move synchronously until the reset push plate 26 is completely pulled out of the reset chute cavity 25. At this time, under the elastic action of the buckle elastic plate 27, the buckle elastic plate 27 will just be engaged in the locking notch 16, and when the movable enclosure plate 1 8 and the movable enclosure plate 2 9 stop moving, the buckle elastic plate 27 and the locking notch 16 is always in a locked state. When the battery pack is in a dangerous situation, the locking notch 16 and the buckle elastic plate 27 further ensure the stability of the side block kit 10 and the enclosure 11 after being inserted into each other, so as to ensure the protection during the detection process. When the detection is completed, as the side block kit 10 and the enclosure 11 are separated from each other, at this time, under the elastic action of the auxiliary spring 29, the reset push plate 26 can be inserted into the reset chute cavity 25 again, and under the guiding action of the reset chute cavity 25, the buckle elastic plate 27 is bent, so that the buckle elastic plate 27 is separated from the locking notch 16, so that the side block kit 10 and the enclosure 11 are separated smoothly.

[0095] During the inspection of the battery pack, when a dangerous situation occurs in the battery pack or a mechanical failure occurs between the equipment, the distance between the movable enclosure plate 1 8 and the movable enclosure plate 2 9 may increase. Under the elastic action of the auxiliary spring 29, the reset push plate 26 may be pushed into the reset chute cavity 25, so that the side block kit 10 and the enclosure 11 are completely separated, and a more adequate protection effect cannot be achieved. At this time, through the set pull rope 2 30, in the process of driving the chute plate 14 to move downward, the driving chute plate 14 close to the movable enclosure plate 1 8 is The L-shaped pull rod 21 on the upper part will move downward synchronously, and finally the L-shaped pull rod 21 will be inserted into the linkage pull ring 24, and pull the magnetic seat 23 to separate from the guide magnetic disk 22. At the same time, the pull rope 19 is pulled to move outward. At this time, under the control of the confluence integration box 20 (wherein, a plurality of fixed pulleys can be provided in the confluence integration box 20 to play a guiding role so that the pull rope 19 can move smoothly. The above are all prior arts and will not be described in detail here), the pull rope 2 30 can be pulled to move synchronously, so that the sliding circular plate 28 drives the buckle elastic plate 2 7 also moves, and the speed is the same as the speed at which the enclosure 11 is inserted into the side block kit 10, so that the locking notch 16 and the buckle elastic plate 27 are always engaged with each other. In addition, by setting the displacement buffer 31, wherein the displacement buffer 31 can adopt a cylindrical structure, and a tension spring is arranged in the cylinder, so that when the speed of the pull rope 19 is not synchronized with the enclosure 11, a certain buffering effect can be provided to avoid rigid pulling. When the battery pack is in a dangerous state or a mechanical failure occurs between the devices, the pull rope 2 30 The pulling force not only causes the buckle elastic plate 27 and the locking notch 16 to move synchronously (to prevent the locking notch 16 and the buckle elastic plate 27 from being disengaged from each other due to the elastic action of the auxiliary spring 29 when a fault occurs), but also increases the pulling force of the buckle elastic plate 27 on the locking notch 16 under the pulling force of the pull rope 19 driven by the inclined slot plate 14, thereby ensuring the stability of the mutual insertion between the side block kit 10 and the enclosure 11. After the inspection is completed, each component returns to its original position to inspect the next battery pack.
