Description

Technical Field

[0001] The utility model relates to the technical field of automobile testing, in particular to a testing device for new energy vehicles. Background Art

[0002] New energy vehicles are vehicles that use unconventional automotive fuels as their power source, and the tires of a car are one of its important components. The stability and reliability of the tires determine the driving safety of the car. Therefore, tires need to be performance tested during production to ensure the reliability of the tire products.

[0003] According to a performance testing device for new energy vehicle tires disclosed (publication number: CN114279723A), in the above application, an electric slider can slide inside the electric slide rail to drive the tire body to perform a rolling test on the corresponding bump section. By setting up two groups, one group can be used as a control group and the other group as an experimental group. In summary, by conducting multiple real simulation tests under test environments with different degrees of unevenness on the ground, the accuracy of the tire body test is effectively improved.

[0004] However, in actual use, the above-mentioned equipment can only test the braking distance of the tire and the driving stability on surfaces with different degrees of unevenness. However, the deflection of the car tire on rough roads cannot be intuitively detected. Due to the uncertainty of the road surface, whether the tire can maintain a high degree of route stability on rough roads determines the driving safety of the car. Therefore, it is necessary to test the deflection performance of the tire. In view of this, we propose a testing device for new energy vehicles. Utility Model Content

[0005] The purpose of the present invention is to provide a testing device for new energy vehicles to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a testing device for new energy vehicles, comprising a base, a road frame fixedly mounted on the upper surface of the base, an auxiliary testing mechanism disposed inside the road frame, and the auxiliary testing mechanism comprising:

[0007] An adjustment chamber is provided inside the road frame, an adjustment seat is fixedly mounted on the inner wall of the adjustment chamber, an adjustment bolt is threadedly connected to the inner wall of the adjustment seat, and a transmission plate is rotatably connected to the top end of the adjustment bolt;

[0008] A transmission rod, wherein the bottom end of the transmission rod is fixedly connected to the upper surface of the transmission plate, and a contact block is slidably mounted on the outer wall of the top end of the transmission rod;

[0009] A contact rod is fixedly installed on the bottom outer wall of the contact block, and a contact switch is fixedly installed on the upper surface of the transmission plate.

[0010] Preferably, a transmission cavity is provided in the inner wall of the contact block. A magnetic block is fixedly installed at the top end of the transmission rod, and a return spring is fixedly connected between the lower surface of the magnetic block and the bottom inner wall of the transmission cavity.

[0011] Preferably, the road frame is arranged in a U shape, and the opening of the road frame faces away from the center of the base, which facilitates the staff to adjust the adjusting bolt.

[0012] Preferably, a rectangular groove with a width adapted to the width of the contact block is provided on the top inner wall of the road frame. The number of contact blocks is set to ten groups, and the ten groups of contact blocks are evenly distributed in the rectangular groove in a linear array. The outer walls of adjacent two groups of contact blocks are in contact with each other, and a scale is provided on the side wall of the contact block close to the end of the rectangular groove, so that the staff can determine the extension distance of the contact block according to the scale of the contact block exposed from the rectangular groove.

[0013] Preferably, an arc surface is provided on the top side of the contact block to reduce the wear of the contact block on the tire surface.

[0014] Preferably, a magnetic plate is provided on the top inner wall of the transmission cavity, and the bottom magnetism of the magnetic plate is the same as that of the magnetic block. Thus, when the contact block is pressed and moves downward, due to the repulsive force between the magnetic plate and the magnetic block, the contact block will quickly reset upward when it is not under pressure.

[0015] Compared with the prior art, the utility model provides a testing device for new energy vehicles, which has the following beneficial effects:

[0016] 1. For the testing device for new energy vehicles, by providing an auxiliary testing mechanism, cooperating with the rectangular groove provided on the road frame and the ten groups of contact blocks provided in the rectangular groove, the direction deviation of the tire during the test of the simulated road condition can be shown more intuitively. At the same time, due to the setting of several contact blocks on the road frame, the staff can accurately measure the offset movement trajectory data of the tire, so as to obtain accurate detection data of the tire, and improve the accuracy and comprehensiveness of the tire performance detection.

[0017] 2. The testing device for new energy vehicles is provided with a magnetic plate having the same magnetic properties as the magnetic block on the top inner wall of the transmission chamber. When the contact block is squeezed and moves downward, the repulsive force between the magnetic plate and the magnetic block causes the contact block to quickly reset upward when no pressure is applied. In addition, due to the influence of the magnetic repulsive force, the contact block can maintain a relatively stable state on the road frame during the test, so that the vibration generated by the tire simulation test will not affect the stability of the contact block that has not been in contact or is about to be in contact, thereby affecting the tire detection test accuracy.

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a testing device for new energy vehicles, comprising a base 1, a road frame 2 is fixedly mounted on the upper surface of the base 1, an auxiliary testing mechanism is arranged inside the road frame 2, and the auxiliary testing mechanism includes an adjustment chamber 3, an adjustment seat 4, an adjustment bolt 5, a transmission plate 6, a transmission rod 7, a contact block 8, a touch rod 9, a contact switch 10, a transmission chamber 11, a magnetic block 12 and a reset spring 13.

[0024] In one embodiment of the present utility model, an adjustment chamber 3 is opened inside the road frame 2, and an adjustment seat 4 is fixedly installed on the inner wall of the adjustment chamber 3. The inner wall of the adjustment seat 4 is threadedly connected to an adjusting bolt 5. The top of the adjusting bolt 5 is rotatably connected to a transmission plate 6, and the upper surface of the transmission plate 6 is fixedly connected to the bottom end of a transmission rod 7. A contact block 8 is slidably installed on the top outer wall of the transmission rod 7, and a touch rod 9 is fixedly installed on the bottom outer wall of the contact block 8. A contact switch 10 is fixedly installed on the upper surface of the transmission plate 6, and a transmission chamber 11 is opened on the inner wall of the contact block 8. A magnetic block 12 is fixedly installed on the top of the transmission rod 7, and a reset spring 13 is fixedly connected between the lower surface of the magnetic block 12 and the bottom inner wall of the transmission chamber 11.

[0025] Further, there are two sets of road frames 2, and the two sets of road frames 2 are mirror - set on the left and right sides of the central axis of the base 1, so as to facilitate simulating the double - wheel driving state of the vehicle. At the same time, there is a gap on the side where the two sets of road frames 2 are close to each other, which is convenient for the installation of external driving devices to complete the setting of the vehicle's driving route and enable it to have enough space for movement. In addition, the road frame 2 is arranged in a U - shape, and the opening of the road frame 2 faces away from the center of the base 1, which is convenient for the staff to control the adjusting bolt 5. Specifically, the transmission plate 6 is slidably connected to the inner wall of the adjusting cavity 3. When the adjusting bolt 5 is rotated, since the adjusting bolt 5 is threadedly connected to the adjusting seat 4, the adjusting bolt 5 will move in the vertical direction, and then drive the transmission plate 6 to move in the vertical direction along the inner wall of the adjusting cavity 3. Cooperating with the transmission rod 7, the height of the contact block 8 is adjusted. Further, a rectangular groove with a width adapted to the width of the contact block 8 is opened on the top inner wall of the road frame 2, and the number of contact blocks 8 is set to ten groups, and the ten groups of contact blocks 8 are evenly distributed in the rectangular groove in a linear array. Specifically, the outer walls of two adjacent contact blocks 8 are in contact, and a scale is provided on the side wall of the contact block 8 close to the end of the rectangular groove, so as to facilitate the staff to determine the extension distance of the contact block 8 according to the scale of the contact block 8 exposed from the rectangular groove, and to facilitate the staff to control and adjust the simulated ground unevenness on the road frame 2, so as to simulate different road conditions for testing.

[0026] In addition, an arc surface is provided on the top side surface of the contact block 8 to reduce the wear of the contact block 8 on the tire surface and avoid the situation that the contact block 8 is stuck in the rectangular groove due to excessive lateral stress when contacting the tire. At the same time, the number of contact switches 10 is set to ten groups, and the ten groups of contact switches 10 are evenly distributed in a linear array on the upper surface of the transmission plate 6, and the contact switches 10 are arranged corresponding to the contact rods 9. So when the tire rolls over the contact block 8, it will generate a downward extrusion force on the contact block 8, and then promote the contact rod 9 and the contact switch 10 to approach each other. The ten groups of contact switches 10 arranged on the transmission plate 6 will connect the corresponding circuits after being pressed and contacted, and this circuit will transmit an electrical signal to an external controller for the staff to observe and monitor. And the design of starting the circuit through the contact of the contact switch 10 and displaying it through an electrical signal adopts the existing technology, so it will not be elaborated here.

[0027] In an embodiment of the present utility model, a magnetic plate is provided on the top inner wall of the transmission chamber 11, and the bottom magnetism of the magnetic plate is the same as that of the magnetic block 12, so that when the contact block 8 is squeezed and moves downward, due to the repulsive force between the magnetic plate and the magnetic block 12, the contact block 8 will quickly reset upward when it is not under pressure, and due to the influence of the magnetic repulsive force, during the test, the contact block 8 can maintain a relatively stable state on the road frame 2, so that the vibration generated by the tire simulation test will not affect the stability of the contact block 8 that has not been contacted or is about to be contacted, thereby affecting the tire detection test accuracy. At the same time, the reset spring 13 is arranged on the outside of the transmission rod 7, so that the reset spring 13 can drive the contact block 8 to reset when relative displacement occurs between the transmission rod 7 and the contact block 8, thereby ensuring the normal progress of the tire detection work.

[0028] In the present invention, when in use, the tire is mounted on a simulated automobile drive component, and the bottom of the tire is in contact with the upper surface of the road frame 2. At this time, the external test equipment is started to prompt the simulated automobile drive component to drive the tire to move linearly along the road frame 2. The external test equipment is used to simulate the braking, normal driving and other actions of the car, and the pressing of the contact block 8 on the road frame 2 on the feeler 9 and the trigger position of the contact switch 10 are observed to observe and judge the driving stability and performance of the automobile tire under different road conditions. At the same time, by providing an auxiliary testing mechanism, cooperating with the rectangular groove opened on the road frame 2 and the ten groups of contact blocks 8 arranged in the rectangular groove, the directional deviation of the tire during the test of the simulated road conditions can be more intuitively displayed. At the same time, due to the setting of several contact blocks 8 on the road frame 2, the staff can accurately measure the tire's offset motion trajectory data, thereby obtaining accurate tire detection data and improving the accuracy and comprehensiveness of tire performance detection.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
