Description

Technical Field

[0001] The utility model relates to the technical field of life test equipment, and particularly relates to a life test device for a control assembly of a new energy vehicle. Background Art

[0002] A high and low temperature test chamber is a device that simulates extreme temperature environments through a precise temperature control system. Currently, experimenters mostly use high and low temperature test chambers to simulate and test the service life of the control assembly of a new energy vehicle in extreme environments.

[0003] Currently, a Chinese patent discloses a multi-axis turntable high and low temperature test chamber (publication number: CN217189644U). Open the door of the test chamber, place the object to be detected on the turntable, adjust the rotating crank. Under the action of the threaded connection between the first lead screw and the turntable and the limiting sliding of the limiting slide bar, drive the clamping plates to approach each other to complete the clamping and fixing of the object to be detected, so as to facilitate subsequent detection operations.

[0004] Since the above device uses the first lead screw to cooperate with a flat clamping plate to clamp the object to be detected, due to the different shapes and quantities of the internal sub-plugs of the control assembly of a new energy vehicle, the shapes of the control assemblies of new energy vehicles are also different. It is difficult for a flat clamping plate to stably clamp the irregular control assembly of a new energy vehicle, and it is difficult to ensure that the control assembly of a new energy vehicle can stably perform shaking and high and low temperature experiments.

[0005] Therefore, a life test device for a control assembly of a new energy vehicle is proposed to solve the above problems. Content of the Utility Model

[0006] The utility model realizes the above object through the following technical solutions. A life test device for a control assembly of a new energy vehicle includes: a high and low temperature test chamber, the inner bottom wall of the high and low temperature test chamber is fixedly connected with a vibration motor, and the top of the vibration motor is fixedly connected with an electric turntable;

[0007] Preferably, a clamping mechanism, the clamping mechanism includes an opposite adjustment component fixedly connected to the top of the electric turntable, the top of the opposite adjustment component is fixedly connected with two adjustment plates, a uniformly distributed installation cavity is opened at the relative end of each of the two adjustment plates, a clamping rod is slidably connected inside the installation cavity, and a metal spring that is always in a compressed state is arranged between the installation cavity and the clamping rod. Adopting a flexible clamping method, this can perform corresponding deformation clamping following the contact surface of the control assembly of a new energy vehicle to meet the clamping requirements of different shapes of the control assembly of a new energy vehicle. At the same time, the clamping rod that is not in contact with the control assembly of a new energy vehicle can also be placed on the side of the control assembly of a new energy vehicle. At this time, the clamping rod can prevent the control assembly of a new energy vehicle from tilting or shifting, and lock the control assembly of a new energy vehicle more stably in place.

[0008] Preferably, the cross-sectional shapes of the clamping rod and the installation cavity are both convex, and the maximum diameter of the clamping rod outside the installation cavity is smaller than the maximum diameter of the clamping rod inside the installation cavity, which can prevent the clamping rod from completely disengaging from the installation cavity to ensure that the clamping rod can operate along a preset trajectory.

[0009] Preferably, a reserved groove is formed at one end of the clamping rod, and one end of the metal spring penetrates into the reserved groove, which can reserve sufficient telescopic space for the metal spring and prevent the metal spring from being damaged due to excessive compression.

[0010] Preferably, the cross-sectional shape of the other end of the clamping rod is semi-circular, which can not only reduce the probability of the clamping rod scratching the new energy vehicle control assembly, but also increase the contact area between the surrounding air and the new energy vehicle control assembly, making the temperature of the new energy vehicle control assembly more uniform.

[0011] Preferably, the opposite adjustment assembly includes a sliding frame fixedly connected to the top of the electric turntable. A bidirectional lead screw is rotatably connected to the inner side of the sliding frame. Threaded sliders slidably connected to the sliding frame are threadedly connected to the surfaces of two opposite threads of the bidirectional lead screw. The bottom parts of the two adjusting plates are respectively fixedly connected to the two threaded sliders. Experimenters can drive the clamping rods on both sides to synchronously clamp and lock the new energy vehicle control assembly through the opposite adjustment assembly, so as to improve the installation rate of experimenters.

[0012] Preferably, one end of the bidirectional lead screw penetrates outside the sliding frame, and an adjustment handle is fixedly connected to one end of the bidirectional lead screw, which can reduce the difficulty for experimenters to rotate the bidirectional lead screw, so as to reduce the adjustment burden of experimenters.

[0013] Preferably, a ratchet is fixedly connected to the surface of the bidirectional lead screw, and a pawl rotatably connected to the sliding frame is meshed with the surface of the ratchet. The direction in which the pawl prevents the ratchet from rotating is the same as the direction in which the bidirectional lead screw drives one of the threaded sliders to move towards the adjustment handle, which can unidirectionally prevent the bidirectional lead screw from loosening and make the new energy vehicle control assembly more stable during the life test.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. Adopting a flexible clamping method, it can perform corresponding deformation clamping following the contact surface of the new energy vehicle control assembly to meet the clamping requirements of different shapes of the new energy vehicle control assembly. At the same time, the clamping rod that does not contact the new energy vehicle control assembly can also be placed on the side of the new energy vehicle control assembly. At this time, the clamping rod can prevent the new energy vehicle control assembly from tilting or shifting, and lock the new energy vehicle control assembly more stably in place;

[0016] 2. The experimenter can drive the clamping rods on both sides to synchronously clamp and lock the control assembly of the new energy vehicle through the opposite adjustment assembly, so as to improve the installation rate of the experimenter. And the design of one-way locking is adopted, which can prevent the two-way lead screw from loosening unidirectionally, making the control assembly of the new energy vehicle more stable for life test.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Specifically implemented as: As Figures 1 - 4 shown, a life test device for the control assembly of a new energy vehicle includes: a high and low temperature test chamber 1, a vibration motor 2 is fixedly connected to the inner bottom wall of the high and low temperature test chamber 1, and an electric turntable 3 is fixedly connected to the top of the vibration motor 2;

[0024] First, the experimenter locks the new energy vehicle control assembly on the top of the electric turntable 3 through the clamping mechanism 4. Then, the experimenter can set the vibration frequency of the vibration motor 2 and the rotation speed of the electric turntable 3. Next, close the door of the high and low temperature test chamber 1 and adjust the temperature inside the high and low temperature test chamber 1 so that the new energy vehicle control assembly operates for a specified time in an environment with corresponding temperature, corresponding vibration frequency, and corresponding rotation speed, in order to test the service life of the new energy vehicle control assembly in the corresponding extreme environment.

[0025] As Figure 2 , Figure 3 and Figure 4 shown, the clamping mechanism 4 includes an opposite adjustment component 41 fixedly connected to the top of the electric turntable 3. The top of the opposite adjustment component 41 is fixedly connected with two adjustment plates 42. Uniformly distributed installation cavities 43 are opened at the opposite ends of the two adjustment plates 42. A clamping rod 44 is slidably connected inside the installation cavity 43. A metal spring 45 that is always in a compressed state is arranged between the installation cavity 43 and the clamping rod 44; the cross-sectional shapes of the clamping rod 44 and the installation cavity 43 are both convex. The maximum diameter of the clamping rod 44 arranged outside the installation cavity 43 is smaller than the maximum diameter of the clamping rod 44 arranged inside the installation cavity 43; a reserved groove 46 is opened at one end of the clamping rod 44, and one end of the metal spring 45 penetrates into the reserved groove 46; the cross-sectional shape of the other end of the clamping rod 44 is semi-circular.

[0026] As Figure 3 and Figure 4 shown, the opposite adjustment component 41 includes a sliding frame 411 fixedly connected to the top of the electric turntable 3. A bidirectional lead screw 412 is rotatably connected to the inside of the sliding frame 411. Threaded sliders 413 that are slidably connected to the sliding frame 411 are threadedly connected to the surfaces of the two opposite threads of the bidirectional lead screw 412. The bottoms of the two adjustment plates 42 are respectively fixedly connected to the two threaded sliders 413; one end of the bidirectional lead screw 412 penetrates to the outside of the sliding frame 411, and an adjustment handle 414 is fixedly connected to one end of the bidirectional lead screw 412; a ratchet 415 is fixedly connected to the surface of the bidirectional lead screw 412, and a pawl 416 that is rotatably connected to the sliding frame 411 is meshed with the surface of the ratchet 415. The direction in which the pawl 416 prevents the ratchet 415 from rotating is the same as the direction in which the bidirectional lead screw 412 drives one of the threaded sliders 413 to move towards the adjustment handle 414;

[0027] When the experimenter needs to lock the new energy vehicle control assembly, the experimenter only needs to rotate the adjustment handle 414 in the corresponding direction. The adjustment handle 414 drives the bidirectional lead screw 412 to rotate. The bidirectional lead screw 412 drives two threaded sliders 413 to slide towards each other along the sliding frame 411 through two opposite threads on the surface. The threaded sliders 413 drive the adjustment plate 42 and the clamping rod 44 to approach the new energy vehicle control assembly until the new energy vehicle control assembly is firmly clamped.

[0028] When the utility model is in use, the experimenter first places the new energy vehicle control assembly between the two clamping rods 44 on both sides, and then adjusts the two adjustment plates 42 towards each other through the opposing adjustment assembly 41. The adjustment plate 42 drives the clamping rod 44 to approach the new energy vehicle control assembly through the installation cavity 43. At this time, the clamping rods 44 on both sides approach the new energy vehicle control assembly towards each other. When the clamping rod 44 on one side comes into contact with the new energy vehicle control assembly in advance, the new energy vehicle control assembly can squeeze the clamping rod 44 into the installation cavity 43 at this time. At this time, the clamping rod 44 on one side deforms correspondingly along the contact surface of the new energy vehicle control assembly until the two clamping rods 44 simultaneously abut against both ends of the new energy vehicle control assembly and abut against the inner wall of the installation cavity 43. At this time, the clamping rods 44 on both sides can stably clamp the new energy vehicle control assembly, and the clamping rod 44 that has not come into contact with the new energy vehicle control assembly can also be placed on the side of the new energy vehicle control assembly. At this time, the clamping rod 44 can prevent the new energy vehicle control assembly from tilting or shifting, and lock the new energy vehicle control assembly more stably in place.

[0029] It should be noted that the specific model specifications of the high and low temperature test chamber 1, the vibration motor 2, and the electric turntable 3 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail. The power supply and its principle of the high and low temperature test chamber 1, the vibration motor 2, and the electric turntable 3 are clear to those skilled in the art and will not be described in detail here.

[0030] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
