[0002] At present, new energy vehicle technology still has defects. Batteries often catch fire during use and charging. Due to the physical characteristics of the battery itself, there is currently no good fire extinguishing solution. The new energy vehicle drum test tests the vehicle's extreme performance, which will cause the vehicle to accelerate or decelerate frequently, which may cause the positive and negative electrodes of the battery pack to heat up rapidly. This heat is the cause of battery combustion.

DETAILED DESCRIPTION

[0044] The present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant inventions, rather than to limit the inventions. It should also be noted that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0045] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0046] Please refer to Figure 1 The present embodiment shown is a schematic diagram of an application scenario of a vehicle emergency evacuation system in an environmental chamber, wherein the environmental chamber 1 has a vehicle test area for providing a test environment for a test vehicle 2, and the environmental chamber 1 is further provided with a plurality of vehicle tying piles 11, and at least two spaced-apart vehicle tying piles 11 are respectively distributed on the front and rear sides of the vehicle test area;

[0047] Furthermore, combined with Figure 2 and Figure 5 , the vehicle emergency evacuation system comprises:

[0048] The untying device 3 comprises: two untying components, each of which comprises a dehooking device 31; the two untying components respectively cooperate with the trailer hooks 21 at the front and rear ends of the test vehicle 2 through the corresponding dehooking devices 31, so as to fix the corresponding trailer hooks 21 with the two adjacent vehicle tying piles 11;

[0049] The vehicle moving device 4 comprises: a driving part and a clamping part that cooperate with each other; the clamping part is formed with four clamping positions, and the four clamping positions are arranged one by one corresponding to the wheels 22 of the test vehicle 2; the driving part is used to drive the clamping part to clamp the corresponding wheel 22, so that the test vehicle 2 can be lifted;

[0050] The traction and dragging device 5 is arranged outside the environmental chamber 1 and is connected to the vehicle moving device 4 via a connecting rope. The traction and dragging device 5 is used to drag the lifted test vehicle 2 out of the environmental chamber 1 .

[0051] In this embodiment, when the test vehicle 2 is subjected to performance testing in the environmental chamber 1, the two untying components are first used to connect the trailer hooks 21 on the front and rear sides of the test vehicle 2 to the vehicle tying piles 11 in the environmental chamber 1 to ensure the stability of the vehicle during the test.

[0052] At the same time, if an emergency such as a fire occurs in the test vehicle 2 during the extreme performance test (for example, the drum test of new energy vehicles), the unhooking device 31 of the untying device 3 can automatically untie the corresponding trailer hook 21 to achieve the rapid release of the test vehicle 2.

[0053] It should be noted that the front and rear sides of the vehicle test area are defined as the front and rear of the vehicle in the usual sense. When the test vehicle 2 enters the vehicle test area, the front side of the vehicle test area is actually the direction of the front of the vehicle, and the rear side of the vehicle test area is the direction of the rear of the vehicle; the trailer hook 21 is provided at the front and rear sides of the test vehicle 2, and the specific position distribution of the vehicle tie-down pile 11 can be found in Figure 2 The test vehicle 2 is provided with two vehicle tying piles 11 at the front and rear, respectively, and the setting positions of the vehicle tying piles 11 cannot hinder the towing out of the vehicle, and no specific limitation is made.

[0054] The clamping portion in the vehicle moving device 4 is formed with at least four clamping positions, and the four clamping positions are arranged in a one-to-one correspondence with the wheels 22 of the test vehicle 2. Under the control of the driving portion, the corresponding wheels 22 are clamped so that the test vehicle 2 can be lifted, thereby avoiding the phenomenon that the test vehicle 2 is currently in the P gear or the parking brake is activated, and the wheels 22 cannot rotate, resulting in the test vehicle 2 being unable to be directly towed out by the traction and dragging device 5.

[0055] In a preferred embodiment, in order to avoid the problem that the vehicle moving device 4 cannot withstand the high and low temperature environment of the environmental chamber 1 due to being in the environmental chamber 1 for a long time.

[0056] The vehicle moving device 4 has a first station and a second station; the first station is arranged outside the environmental chamber 1; the second station is arranged inside the environmental chamber 1 and corresponds to the fixed position of the test vehicle 2; for details, see Figure 1 and Figure 2 The position of the vehicle moving device 4 is shown, wherein Figure 1 The vehicle moving device 4 is at the first working position, Figure 2 The vehicle moving device 4 is in the second working position.

[0057] Among them, the situation corresponding to the first workstation may be that the test vehicle 2 is undergoing performance testing in the environmental chamber 1, and when an emergency such as a fire occurs in the test vehicle 2, the vehicle moving device 4 needs to be switched from the first workstation to the second workstation, enter the environmental chamber 1 to lift the test vehicle 2, and after the lifting is completed, the vehicle moving device 4 moves again to the first workstation, and the test vehicle 2 is also dragged out of the environmental chamber 1 at the same time.

[0058] The traction and drag device 5 is connected to the vehicle moving device 4 through the circular rope structure 6, so the traction and drag device 5 can control the position of the vehicle moving device 4 by retracting and releasing the circular rope, that is, the vehicle moving device 4 is controlled to switch between the first workstation and the second workstation through the circular rope structure 6, thereby realizing the function of adjusting the position of the vehicle moving device 4, and also assuming the function of towing the test vehicle 2 out through the vehicle moving device 4.

[0059] In a preferred embodiment, see Figure 3 and Figure 4 The untying assembly includes: at least two unhooking devices 31; the number of unhooking devices 31 in the untying assembly is set corresponding to the number of the front and rear side tying piles 11 of the test vehicle 2.

[0060] A bow-shaped shackle 32 is respectively provided at both ends of the unhooking device 31; one of the bow-shaped shackles 32 in the unhooking device 31 is connected to the trailer hook 21, and the other bow-shaped shackle 32 is fixed to the vehicle tying pile 11 adjacent to the trailer hook 21 through the vehicle tying iron chain 12, thereby ensuring that the test vehicle 2 is fixed when the performance test is performed;

[0061] When an emergency occurs, the unhooking device 31 releases the bow-shaped shackle 32 connected to the trailer hook 21 to separate the test vehicle 2 from the vehicle tie-down pile 11. For specific separation states, see Figure 4 .

[0062] The principle of the release device 31 releasing the corresponding bow-shaped shackle 32 is as follows: the specific structure of the untying assembly includes, in addition to the release device 31 and the bow-shaped shackle 32, a cylinder 33, a spring pin 34, a pin-pulling wire 35 and a swing arm wire 36. When the test vehicle needs to be automatically untied in an emergency, the cylinder 33 pulls out the spring pin 34 through the pin-pulling wire 35, and then rotates the swing arm 37 through the swing arm wire 36. After the swing arm 37 rotates, the clamping block 38 of the bow-shaped shackle 32 is driven to rotate through the fixed pin shaft. After the clamping block 38 rotates, it opens and releases the bow-shaped shackle 32, thereby realizing the automatic untying of the test vehicle 2 from the vehicle tying pile 11.

[0063] In a preferred embodiment, see Figure 7 To ensure that after the untying device 3 is untied, the unhooking device 31 can be quickly retracted and locked to prevent rebound, and there are no obstacles on the evacuation passage of the test vehicle, the vehicle emergency evacuation system also includes:

[0064] An unbinding and recovery device 8, which is disposed inside the environmental chamber 1 and is used to cooperate with the unbinding component located at the rear side of the test vehicle 2;

[0065] The untying and recovering device 8 includes at least two untying and recovering parts, which are arranged on both sides of the test vehicle 2 and are respectively connected to the two unhooking devices 31 in the corresponding untying components through steel wire ropes.

[0066] Specifically, the untying and recovering part is composed of a swivel arm 81 and a swivel arm bracket 82, and there is a leaf spring mechanism 83 on the swivel arm 81; the swivel arm 81 is connected to the bow-shaped shackle 32 in the unhooking device 31 (the bow-shaped shackle 32 should be the bow-shaped shackle 32 connected to the vehicle tying pile 11) through a steel wire rope, and the leaf spring mechanism 83 can quickly retract the unhooking device 31 and lock it to prevent rebound after the untying device 3 unties the test vehicle 2.

[0067] In a preferred embodiment, see Figure 5 , in order to ensure that the vehicle moving device 4 can adapt to the movement of various types of vehicles, the vehicle moving device 4 also includes: two support plates 41;

[0068] The two support plates 41 are connected via a scissor mechanism 411, and the scissor mechanism 411 is used to adjust the distance between the two support plates 41; here, the scissor mechanism is a conventional mechanical structure, which can adjust the distance between the two support plates 41 by telescoping to adapt to vehicle models with different wheelbases.

[0069] The driving portion and the clamping portion are disposed on the support plate 41 ; the four clamping positions are respectively located on two opposite sides of the two support plates 41 , and the two clamping positions on the same support plate 41 are correspondingly disposed.

[0070] In a specific usage scenario, the two support plates 41 are each provided with a clamping position on the left and right sides, so one support plate 41 is used to clamp the left and right wheels 22 of the front axle of the test vehicle 2, and the other support plate 41 is used to clamp the left and right wheels 22 of the rear axle of the test vehicle 2; in addition, in order to ensure the smooth movement of the vehicle moving device 4, a roller 48 is also provided at the bottom of the support plate 41.

[0071] In a preferred embodiment, see Figure 5 and Figure 6 The clamping portion includes: four swing arm groups, the four swing arm groups are respectively located on two opposite sides of the two support plates 41, and the two swing arm groups located on the same support plate 41 are correspondingly arranged.

[0072] Specifically, each swing arm group includes: a first swing arm 42 and a second swing arm 43, wherein the clamping position is formed between the first swing arm 42 and the second swing arm 43 for clamping the wheel 22;

[0073] It should be noted that defining the two swing arms in the swing arm group as the first swing arm and the second swing arm is only for the purpose of describing the scheme clearly and facilitating the distinction between components. In essence, there is no distinction between the first and the second.

[0074] In addition, the driving part includes a transmission structure corresponding to each swing arm group;

[0075] Combination Figure 6 As shown, the transmission structure includes: a driving member and a lead screw 44 rotatably connected to the driving member, the rod body of the lead screw 44 is formed with two transmission areas, and the lead screw threads in the two transmission areas are arranged in reverse threads; the lead screw 44 is threadedly connected to two connecting blocks 45, and the two connecting blocks 45 are respectively arranged in the two transmission areas, and the lead screw 44 is used to drive the connecting blocks 45 to perform linear motion along the extension direction of the lead screw 44; wherein, the two connecting blocks 45 are respectively hinged to the first swing arm 42 and the second swing arm 43 in the same swing arm group through a movable rod 46.

[0076] Specifically, the type of driving member can be selected as a motor. In the embodiment of the present application, a motor and a chain 47 cooperate to drive the lead screw 44 to rotate. The specific implementation method is, for example, that the output shaft of the motor is provided with a driving gear, and a driven gear is provided on a rotating rod arranged at the bottom of the support plate 41. The driving gear, the driven gear and the chain 47 are meshed with each other, and two lead screws 44 with reverse threads are fixed at both ends of the rotating rod to form two transmission areas; at the same time, the lead screw 44 is arranged at the bottom of the support plate 41 through a support part, and a bearing for supporting the rotation of the lead screw 44 also needs to be provided in the support part.

[0077] The lead screw 44 drives the two connecting blocks 45 to make linear reciprocating movements during the rotation process. Since the threads contacted by the two connecting blocks 45 are reverse threads, the two connecting blocks 45 on the same lead screw 44 will move closer to or away from each other. Since the two connecting blocks 45 are respectively hinged to the first swing arm 42 and the second swing arm 43 in the same swing arm group through the movable rod 46, when the two connecting blocks 45 move away from each other, the first swing arm 42 and the second swing arm 43 are in an open state, otherwise the two swing arms are in a clamped state.

[0078] In a preferred embodiment, see Figure 2 The traction and dragging device 5 includes: an electric winch 51 and a support frame 52;

[0079] The electric winch 51 is used to provide driving force for towing the test vehicle 2 , and an encoder is provided on the electric winch 51 , and the encoder is used to position the vehicle moving device 4 ; the support frame is used to support the electric winch 51 .

[0080] Specifically, the electric winch 51 is mainly used to retract and release the circulating rope structure 6 to realize the operation and movement of the vehicle moving device 4 or the workstation switching, and the encoder records the number of rotations of the motor in the electric winch 51, and locates the position of the vehicle moving device 4 through the number of rotations of the motor, thereby playing an auxiliary positioning role.

[0081] In a preferred embodiment, see Figure 2 The vehicle emergency evacuation system also includes: a guide groove 13. The specific form of the guide groove 13 is actually a ground groove. The corresponding "circulating rope structure" mentioned above will also be arranged in the ground groove. Under the guiding effect of the guide groove 13 on the circulating rope structure 6, the test vehicle 2 can be dragged out of the environmental chamber 1 in an upright manner.

[0082] Specifically, the guide groove 13 extends from inside the environmental chamber 1 to outside the environmental chamber 1 along the length direction of the test vehicle 2, and is used to provide guidance for the endless rope structure 6 to ensure that the test vehicle 2 can be towed out smoothly and quickly.

[0083] A limiting device is also provided inside the guide groove 13, and the limiting device is located outside the environmental chamber 1. When the vehicle moving device 4 runs to the specified position outside the environmental chamber 1, the bottom of the vehicle moving device 4 will touch the limiting device, and the limiting device will issue an instruction to stop the traction and dragging device 5, and the vehicle moving device 4 can stop; here, the instruction stop signal of the limiting device can rely on the pressure sensor device. When the pressure sensor on the limiting device collects a certain pressure value, it means that the vehicle moving device 4 has reached the specified position, and a corresponding instruction can be issued.

[0084] In a preferred embodiment, see Figure 2 , because the battery itself has the three elements of combustion, combustibles, combustion-supporting materials and ignition sources. It is extremely difficult to extinguish the fire with traditional fire extinguishing methods, and most new energy vehicle batteries are lithium batteries or hydrogen fuel cells, which are at risk of explosion at any time. The vehicle emergency evacuation system also includes:

[0085] The spray smoke exhaust device 7 is arranged outside the environmental chamber 1 and can be arranged corresponding to the restriction device. Of course, it can also be arranged near the door of the environmental chamber 1. There is no special limitation on the specific situation. The spray smoke exhaust device 7 is used to spray the test vehicle 2 and exhaust the generated smoke. Such a design enables the spray smoke exhaust device 7 to immediately perform fire extinguishing operation after the test vehicle 2 is dragged out of the environmental chamber 1 due to fire.

[0086] It should be noted that in order to ensure that the various devices in the vehicle emergency evacuation system can cooperate with each other, the vehicle emergency evacuation system also includes a control device, which includes: an electric control cabinet and an operation panel; the control device is used to control the coordinated operation of the various components of the vehicle emergency evacuation system, and the specific control logic will not be repeated.

[0087] In summary, the specific working principle of the embodiment of the present application is as follows:

[0088] Prepare before the test, measure the wheelbase of the test vehicle 2, and adjust the scissor mechanism 411 in the middle of the vehicle moving device 4 according to the measurement result, so that its length meets the wheelbase requirement of the test vehicle 2 and can lift the test vehicle smoothly. Then, use the vehicle tying chain 12 and the untying device 3 to fix the test vehicle 2 and the vehicle tying pile 11, and move the vehicle moving device 4 out of the environmental chamber 1.

[0089] When the laboratory personnel find that the test vehicle 2 is abnormal and there is a risk of fire, they will turn off the drum equipment, open the hatch of the environmental chamber 1, and start the vehicle emergency evacuation system. After the vehicle emergency towing system confirms that the drum has stopped running and the hatch is fully opened, the towing and towing device 5 first rotates in the opposite direction to tow the vehicle moving device 4 from outside the environmental chamber 1 to the designated position inside the environmental chamber 1, and pre-clamps the wheel 22. The emergency towing system controls the untying device 3 to automatically untie the test vehicle 2 and the vehicle tying chain 12, realizing the automatic untying function of the test vehicle 2.

[0090] After the test vehicle 2 is untied, the unbinding device 3 is quickly retracted by the unbinding recovery device 8. At this time, the vehicle moving device 4 lifts the test vehicle by clamping the tires through the first swing arm 42 and the second swing arm 43. When the vehicle moving device lifts the test vehicle into place, the traction and towing device 5 drags the test vehicle 2 from the environmental chamber 1 to the designated position through the circulating rope structure 6. The fire is controlled by the spray smoke exhaust device 7, which reduces the surface temperature of the burning vehicle and greatly reduces the possibility of overheating and explosion of the burning vehicle, thereby protecting the buildings, test facilities and the personal safety of operators.

[0091] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
