Description

Technical Field

[0001] The invention relates to the technical field of battery temperature detection, in particular to an automobile battery operating temperature detector. Background Art

[0002] There are two types of automotive batteries: storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, including lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries.

[0003] Common battery temperature detection is simply to connect the power supply and load to perform temperature detection on the battery. However, the car battery will shake and tilt during use. At this time, conventional temperature detectors cannot simulate such conditions.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0022] In one embodiment, see Figure 1-Figure 7, a car battery working temperature detector, including a workbench 1, the workbench 1 is placed horizontally for supporting the entire temperature detector, downwardly inclined support feet 28 can be set at the four corners of the workbench 1, and the workbench 1 is supported by the support feet 28, so that there is enough space under the workbench 1 to install a drive unit, which is convenient for the subsequent work of the detector, and a support column 3 is vertically arranged in the middle of the workbench 1, the support column 3 can slide up and down in the middle of the workbench 1, and an articulated seat 9 is provided at the upper end of the support column 3, and the upper end of the articulated seat 9 is connected to the middle of the lower surface of the battery mounting groove 2. On the one hand, the up and down movement of the support column 3 can drive the battery mounting groove 2 to move up and down, and on the other hand, the battery mounting groove 2 can be pitched, tilted and deflected forward, backward, left and right along the upper end of the support column 3 through the articulated seat 9, thereby simulating the movement of the car During driving, due to the different heights of the four tires, the battery tilts and fluctuates up and down. The upper surface of the battery mounting slot 2 is provided with a groove structure, and the battery can be fixed inside the groove by bolt connection, and a power supply device and a load device are provided inside the battery mounting slot 2. The load device can simulate the state of the vehicle battery outputting to the vehicle, and the power supply device can simulate the state of the vehicle reversely charging the vehicle battery, that is, the discharge and charging of the battery can be simulated in the battery mounting slot 2, and the voltage can also be adaptively adjusted to simulate the state of vehicle load changes, and a temperature detection device is also provided to detect the temperature of the vehicle battery in real time. These are all conventional adjustments, and the specific working state will not be repeated. It also includes a push rod 4, a tilting drive component 7 and an ups and downs drive component 8;

[0023] The ups and downs driving assembly 8 is arranged in the middle of the lower surface of the workbench 1. The ups and downs driving assembly 8 can drive the support column 3 to move up and down, so that the entire mounting slot battery mounting slot 2 moves up and down, thereby simulating the rising or falling state of the car on the undulating road surface;

[0024] The push rod 4 is arranged below the four corners of the battery installation slot 2, and the push rod 4 is vertically arranged and slidably connected to the workbench 1. A ball head 27 is arranged at the upper end of the push rod 4, and the ball head 27 always presses against the lower surface of the battery installation slot 2. If one of the push rods 4 moves upward, the corner of the battery installation slot 2 will rise upward adaptively, so that the battery installation slot 2 is in a tilted state. At this time, it is simulated that when the four tires of the car are at different heights, the car as a whole is tilted, and the car battery is also in a tilted state;

[0025] The tilt drive assembly 7 is arranged on the front and rear sides of the workbench 1 and is used to adjust the height of the four push rods 4. The tilt drive assembly 7 always keeps the ball head 27 at the upper end of the push rod 4 in contact with the battery mounting slot 2 to avoid the problem of the battery mounting slot 2 being stuck due to the different rising heights of the four push rods 4.

[0026] In one case of this embodiment, a limit plate 5 is provided on the side of the push rod 4 close to the ground, and a shock-absorbing spring 6 is provided between the limit plate 5 and the workbench 1 to drive the push rod 4 to move toward the side away from the ground. The limit plate 5 is provided at the lower end of the push rod 4, and because the shock-absorbing spring 6 always pushes the push rod 4 upward, the ball head 27 at the upper end of the push rod 4 always maintains a state of being in contact with the lower surface of the battery mounting slot 2. When the battery mounting slot 2 is tilted, the ball head 27 can slide on the lower surface of the battery mounting slot 2. During the driving of the vehicle, when the wheels drive on the undulating road surface of the high ground, the suspension of the vehicle will buffer a part of the fluctuation. The shock-absorbing spring 6 of this detector plays the role of simulating the buffering effect of the vehicle suspension, and the shock-absorbing spring 6 can also be replaced with a more sophisticated shock absorber according to different working conditions. The final effect is to simulate the effect of vehicle suspension buffering. In this application, a shock-absorbing spring 6 with a relatively simple structure is used.

[0027] In one case of the present embodiment, the ups and downs driving assembly 8 includes a mounting frame 15 arranged at the lower end of the support column 3, the middle part of the mounting frame 15 is rotatably connected with a guide wheel 14 arranged in a front-to-rear direction, the lower part of the guide wheel 14 is in contact with the upper surface of a traction belt 16 in a left-to-right direction, and the traction belt 16 passes through the gap between the lower side of the mounting frame 15 and the guide wheel 14, so the U-shaped mounting frame 15 can prevent the traction belt 16 from falling off, and an ups and downs hydraulic cylinder 18 is arranged on the right side of the lower surface of the workbench 1, the piston rod of the ups and downs hydraulic cylinder 18 extends to the left side and the extension length and pressure can be freely controlled, the piston rod of the ups and downs hydraulic cylinder 18 is fixedly connected to the traction plate 17, and the left side of the traction plate 17 is connected The right end of the traction belt 16 is connected to the left end of the lower surface of the workbench 1. At this time, when the piston rod of the ups and downs hydraulic cylinder 18 is extended or retracted, the traction belt 16 can be used to pull the support column 3 up and down, thereby changing the height of the support column 3, that is, changing the height of the battery mounting slot 2. And because the traction belt 16 is made of flexible material, when the piston rod of the ups and downs hydraulic cylinder 18 is quickly extended, the traction belt 16 will relax, so that the support column 3 has a state of falling only by gravity, that is, simulating the state of the battery mounting slot 2 falling rapidly, thereby simulating the state of the vehicle jumping and falling after quickly passing through the high slope, thereby improving the realism of the vehicle's driving state.

[0028] If only the left end of the traction belt 16 is connected to the workbench 1, the up and down simulation can be realized, but this will cause the traction belt 16 to be easily damaged by sudden tension for a long time. At the same time, during the driving of the vehicle, the deformation of the tire and the suspension makes the height change of the vehicle itself have a buffering effect. Therefore, the left and right sides of the workbench 1 are provided with a left-right mounting frame 10, and the lower end of the mounting frame 10 is fixedly connected to the left-right sliding rod 11, and the middle part of the sliding rod 11 is slidably connected to the slider 12. The left slider 12 is connected to the traction belt 16. A buffer spring 13 is arranged at the left end of the guide belt 16 and between the left slider 12 and the mounting frame 10. The buffer spring 13 can simulate the buffering effect brought by the suspension and tire deformation of the vehicle after jumping to a certain extent. At the same time, the buffer spring 13 can also protect the traction belt 16 and improve the service life of the traction belt 16. The slider 12 on the right is fixedly connected to the traction plate 17, so that the piston rod of the ups and downs hydraulic cylinder 18 only needs to push the traction plate 17 to move left and right, thereby avoiding the piston rod of the ups and downs hydraulic cylinder 18 from being damaged by lateral force, thereby improving the service life of the ups and downs hydraulic cylinder 18.

[0029] In one case of the present embodiment, the tilting drive assembly 7 includes a slide groove 25 arranged on both sides of the workbench 1, the slide groove 25 is arranged on the front and rear sides of the upper surface of the workbench 1 in a left-right direction, and a push block 24 arranged in a left-right direction is slidably connected in the middle of the slide groove 25, and a top block 22 is arranged on the left and right ends of the upper surface of the push block 24, and the upper end of the top block 22 is an inclined surface inclined toward the middle of the slide groove 25, and an extension beam 19 is arranged on the side of the push rod 4 close to the slide groove 25, and an extension frame 20 is arranged at the end of the extension beam 19, and the extension frame 20 is rotatably connected to a top wheel 21 that cooperates with the top block 22. When the top wheel 21 contacts the top block 22, it moves in a direction away from the ground. For example, when the push block 24 moves to the left, the top block 22 at the left end of the push block 24 will contact the top wheel 21. When the push block 24 is in the middle of the slide groove 25, the push blocks 22 on both sides of the push block 24 are not in contact with the top wheel 21. That is to say, when the push block 24 is centered, the push rod 4 will not be blocked by the top block 22 when it moves up and down, thereby simulating the state of the vehicle jumping. In addition, since a shock-absorbing spring 6 is provided at the lower end of the push rod 4 and a counterweight is provided inside the battery mounting groove 2, after the automobile battery is installed in the battery mounting groove 2, the center of gravity of the entire battery mounting groove 2 coincides with the center. Therefore, if there is no external force, the battery mounting groove 2 will eventually tend to a horizontal state. At this time, the push rod 4 is in an initial state, thereby avoiding the problem of interference between the top block 22 and the top wheel 21 when the push block 24 moves in the opposite direction. In order to drive the push block 24 to move left and right, a tilting hydraulic cylinder 26 is arranged on the front and rear sides of the upper surface of the workbench 1. The piston rod of the tilting hydraulic cylinder 26 extends to the left, and the piston rod of the tilting hydraulic cylinder 26 is fixedly connected to the push plate 23, and the push plate 23 is fixedly connected to the middle part of the push block 24. Therefore, the extension length of the piston rod of the tilting hydraulic cylinder 26 can be freely controlled, so that the push block 24 can be pushed to any position of the slide groove 25, that is, the upper battery mounting groove 2 can be pushed to different tilt angles.

[0030] During the implementation of this embodiment, the entire detector is stably placed on the ground. Since the car battery is heavy, the lower end of the support foot 28 can be directly fixed to the ground by bolt connection, the car battery is installed in the battery installation slot 2, and the power supply device, load device and temperature detection device are connected to the car battery. At this time, the preparation of the detector is completed.

[0031] The vehicle jumping state is simulated by starting the tilting hydraulic cylinder 26 to move the push block 24 to the middle of the slide groove 25. At this time, the top block 22 is disengaged from the top wheel 21. Under the action of the shock-absorbing spring 6, the battery mounting slot 2 tends to be horizontal. The ups and downs hydraulic cylinder 18 is quickly started, and the piston rod of the ups and downs hydraulic cylinder 18 is quickly retracted and then extended. When the ups and downs hydraulic cylinder 18 is retracted, the traction belt 16 is tightened, causing the support column 3 to move upward rapidly, thereby simulating the rapid rising state of the vehicle in the uphill process. When the ups and downs hydraulic cylinder 18 is extended, the traction belt 16 is relaxed, causing the support column 3 to move downward rapidly. The temperature detection device in the battery mounting slot 2 will record the temperature change in real time, and the load of the battery can be increased during the rising of the support column 3, thereby simulating the increase in battery output when the vehicle climbs a slope, and the moving range of the piston rod of the ups and downs hydraulic cylinder 18 can be adjusted to simulate different heights of vehicle jumps.

[0032] The state of the vehicle on the uneven road section is simulated, and the ups and downs hydraulic cylinder 18 is switched to the pressure control state, so that the support column 3 maintains a certain upward trend, so that the support column 3 can lift the battery installation slot 2, and the tilt hydraulic cylinder 26 is started at this time. The piston rod of the tilt hydraulic cylinder 26 extends or contracts to change the position of the push block 24 in the slide slot 25. After the top block 22 contacts the top wheel 21, the corresponding top rod 4 will rise. The two tilt hydraulic cylinders 26 can be adjusted synchronously and adaptively, and the traction belt 16 always maintains the lifting effect, so that the top rod 4 only plays the role of changing the inclination angle of the battery installation slot 2, avoiding The interference problem caused by the poor coordination between the top rod 4 and the support column 3 is solved. At this time, the battery mounting slot 2 is tilted, that is, the upper car battery is tilted, thereby simulating the tilt change caused by the vehicle driving on an uneven road surface, and the extension distance of the piston rod of the tilt hydraulic cylinder 26 can adjust the size of the tilt angle, that is, simulate the different depths of road potholes, and at the same time, the extension speed of the piston rod of the tilt hydraulic cylinder 26 can adjust the speed of the vehicle's tilt angle change, that is, the speed of the vehicle when driving. If the vehicle is driving at a faster speed, it will cause the tilt change to be faster on an uneven road surface.

[0033] Both the tilting hydraulic cylinder 26 and the heave hydraulic cylinder 18 can be controlled by a computer program, so that the height and tilt angle of the battery mounting slot 2 can be adjusted more accurately according to different working conditions. For example, the vehicle jumping in a tilted state can be simulated. These are subsequent program design issues and do not affect the basic vehicle state simulation effect of the detector. The detector also has a hardware foundation for more accurate simulation.

[0034] The present invention is applicable to an automobile battery working temperature detector, which simulates the vehicle's jerking and bouncing driving condition by tightening and loosening the traction belt 16, and the push rod 4 drives the battery installation slot 2 to tilt to simulate the state of the vehicle passing through the uneven road surface, so that the detector can restore the state of the vehicle during driving, and also makes the final temperature detection value more consistent with the actual vehicle use condition, thereby improving the reliability of the data.

[0035] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
