In addition, if "and / or" appears in the full text, its meaning is that it includes three parallel solutions, taking "A and / or B as an example", including solution A, or solution B, or a solution that satisfies both A and B.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] Please refer to Figure 1, which is a three-dimensional structural schematic diagram of a test module of a tire testing device provided by an embodiment of the utility model in a descending state, wherein the tire testing device comprises a bracket 10 and a test module 20 for carrying a tire.

[0027] Among them, the test module 20 is arranged on the bracket 10, including a lifting platform 210 and two rollers 220 rotating with the tire, the two rollers 220 are arranged opposite to each other at a first interval, the lifting platform 210 is arranged between the two rollers 220, and can be at least flush with the two rollers 220 when raised, and lower than the two rollers 220 when lowered.

[0028] Specifically, please combine Figure 2 , 3 The bracket 10 is made of multiple profiles, and the test module 20 is arranged on the bracket 10 to carry the tire to be tested; the tested vehicle here can be a two-wheeled motorcycle, a battery vehicle, or a tricycle, or a four-wheeled car. When the tested vehicle is a two-wheeled motorcycle or a battery vehicle, two of the test modules 20 are arranged on the bracket 10 one in front and one in the back; when the tested vehicle is a tricycle, three of the test modules 20 are arranged in a three-point layout on the bracket 10; when the tested vehicle is a four-wheeled car, four of the test modules 20 are arranged on the bracket 10 in two in the front and two in the back, and each of the test modules 20 includes a lifting load platform 210 and two rollers 220, and the two rollers 220 are relative and They are arranged parallel to each other, with the first spacing between them. The roller 220 here can be an unpowered roller, which can rotate under external force, such as when the wheel rotates above it, the unpowered roller 220 can rotate under the friction of the tire; it can also be a powered roller with driving force. Whether the roller 220 is powered depends mainly on whether the tire of the tested vehicle has driving force. For example, if the tested four-wheel vehicle is a front-wheel drive vehicle, the rollers 220 of the front two test modules 20 need to be unpowered rollers, and the rollers 220 of the rear two test modules 20 need to be driven rollers. Similarly, the opposite is true for rear-wheel drive vehicles. For four-wheel drive vehicles, the rollers 220 of the four test modules do not need to have driving force.

[0029] The lifting platform 210 is disposed between the two rollers 220 and can be freely lifted and lowered. For example, when the lifting platform 210 is lifted, the top surface of the lifting platform 210 can be at least flush with the top surfaces of the rollers 220 on both sides thereof (e.g. Figure 2 As shown), the vehicle can be parked on the lifting platform 210. When the tire needs to be tested, the lifting platform 210 only needs to be lowered to be lower than the roller 220 (as shown). Figure 1As shown), at this time, the tire side of the vehicle is suspended between the two rollers 220, and then the vehicle is turned on to rotate the wheels. The rollers 220 will also rotate under the action of the wheels, and the vehicle will not be displaced, thereby achieving the effect of in-situ testing, simulating the actual test scenario, and solving the problems of multiple test sites, large floor space, low test efficiency, large number of personnel, and great safety hazards.

[0030] Furthermore, in other preferred embodiments of the present invention, the roller 220 can be replaced with different types of rollers, and the different types of rollers include rollers with a silicone layer, or a rubber layer, or rollers with convex points of different shapes on the surface.

[0031] Here, the roller 220 is replaceable. When in use, different types of the roller 220 can be replaced according to different test scenarios and needs. Specifically, the roller 220 can be replaced with a silicone layer, a rubber layer, or rollers with different shapes of convex points on the surface. In this way, different road conditions can be simulated through the silicone layer, the silicone layer, and the convex point layers of different shapes, and the test scenarios can be easily switched to improve the test efficiency.

[0032] Furthermore, both ends of the roller shaft 220 are detachably connected to the bracket 10 via spring pins 30 .

[0033] Specifically, the two ends of the roller shaft 220 are provided with the spring pins 30, and the spring pins 30 can be used to achieve a detachable connection between the roller shaft 220 and the bracket 10, so as to facilitate the rapid replacement of the roller shaft 220 under different test environments.

[0034] In addition, in other preferred embodiments of the present invention, the bracket 10 includes a first mounting frame 110, a second mounting frame 120 and a bottom plate 130;

[0035] The two first mounting frames 110 are arranged opposite to each other and their bottoms are mounted on the bottom plate 130 , and the two second mounting frames 120 are arranged opposite to each other and their bottoms are mounted on the bottom plate 130 ;

[0036] The two rollers 220 are respectively connected between the two first mounting frames 110 and between the two second mounting frames 120 . The size of the first interval can be adjusted by adjusting the mounting positions of the first mounting frames 110 and the second mounting frames 120 on the bottom plate 130 .

[0037] Specifically, as shown in the figure, the first mounting frame 110 and the second mounting frame 120 can be channel steel components, one of which is mounted on the bottom plate 130, and its web is used to mount the roller shaft 220. Here, both ends of the roller shaft 220 are detachably connected to the first mounting frame 110, that is, the web of the channel steel component, through the spring pin 30; the two first mounting frames 110 are arranged opposite to each other, and the two ends of one of the roller shaft 220 are respectively connected between the two first mounting frames 110; the two second mounting frames 120 are also arranged opposite to each other, and the two ends of the other roller shaft 220 are respectively connected to the first mounting frames 110; The ends are respectively connected between the two second mounting frames 120; the mounting positions of the first mounting frame 110 and the second mounting frame 120 on the base plate 130 are not fixed, but adjustable. For example, different mounting holes are provided on the first mounting frame 110, the second mounting frame 120 and the base plate 130. By setting fasteners on different mounting holes, the distance between the first mounting frame 110 and the second mounting frame 120 can be adjusted, and the first distance between the two rollers 220 can be adjusted in turn to match tires with different wheel diameters, thereby expanding the scope of use of the equipment.

[0038] In addition, in other preferred embodiments of the present invention, the lifting support platform 210 includes a linear drive device 2101 arranged on the base plate 130 and a support platform 2102 connected to the top of the linear drive device 2101. The linear drive device 2101 is preferably a hydraulic cylinder to provide more reliable thrust and support force, or it can also be a pneumatic cylinder, a linear electric cylinder, etc.

[0039] Specifically, the base plate 130 is detachably connected to the top of the bracket 10 by means of screws and other connecting parts. The lifting platform 210 is lifted and lowered by a hydraulic lifting device. The bottom of the linear drive device 2101 is fixed to the side of the base plate 130 away from the bracket 10. The top of the linear drive device 2101 is connected to the platform 2102. The width of the platform 2102 should be smaller than the first spacing between the two rollers 220 to ensure that the lifting platform 210 can be freely lifted and lowered.

[0040] It should also be pointed out that if the height of the linear drive device 2101 is relatively large, greater than the thickness of the first mounting frame 110 and the second mounting frame 120, then a mounting plate 140 needs to be set up. The mounting plate 140 serves as a mounting base plate for the first mounting frame 110 and the second mounting frame 120, and has the same function as the base plate 130. The mounting plate 140 is arranged above the base plate 130 and is connected to the base plate 130 through mounting rods 150 at the four corners. At this time, a through hole for the linear drive device 2101 to pass through should be set on the mounting plate 140.

[0041] Furthermore, in other preferred embodiments of the present invention, the bracket 10 also includes a first profile slide 101 for carrying the test module 20, and the base plate 130 is arranged on the first profile slide 130 and can move thereon along its length direction.

[0042] Specifically, the test module 20 is not fixed on the bracket 10, but the base plate 130 can be moved back and forth along the length direction of the first profile slide 101 through the first profile slide 101. The purpose of this design is that when there are two test modules 20 on the first profile slide 101, that is, when testing a three-wheeled or four-wheeled vehicle, the distance between the two test modules 20 can be adjusted to match vehicles with different wheelbases.

[0043] Furthermore, in other preferred embodiments of the utility model, the bracket 10 also includes a second profile slide 102, both ends of the first profile slide 101 are connected to two second profile slides 102 and can move along the length direction thereof, two first profile slides 101 are arranged at intervals between the two second profile slides 102, and two test modules 20 are arranged at intervals on each of the first profile slides 101.

[0044] Specifically, the two first profile slide grooves 101 are not fixed, and the distance between them is adjustable. Through the second profile slide groove 102, the two first profile slide grooves 110 can be reciprocated along the length direction of the second profile slide groove 102, thereby adjusting the distance between the two. The purpose of such a design is to match vehicles with different wheelbases by adjusting the distance between the two first profile slide grooves 101.

[0045] In summary, by setting the first profile chute 101 and the second profile chute 102, the test module 20 can be moved on the plane where the first profile chute 101 and the second profile chute 102 are located, that is, within the horizontal coordinate system, so as to adjust the position of each test module 20 on the X-axis and Y-axis, so as to match different vehicle models and expand the scope of use of the tire testing equipment.

[0046] More specifically, the two first profile chutes 101 are arranged at a distance between the two second profile chutes 102, one in front and one behind, corresponding to the front and rear axles of the four-wheeled vehicle respectively, and each of the first profile chutes 101 is provided with two of the test modules 20, and each two of the test modules 20 are also arranged at a distance, so that they correspond to the wheels on the left and right sides of the four-wheeled vehicle, thus forming a relatively typical four-wheeled vehicle tire testing equipment.

[0047] It can be imagined that the three-wheel vehicle tire testing equipment is a test module 20 provided on one of the first profile chutes 101, and two test modules 20 are provided on the other first profile chutes 101; the two-wheel vehicle tire testing equipment is a test module 20 provided on each of the two first profile chutes 101; of course, there can also be multi-wheel vehicle (such as five-wheel, six-wheel, etc.) tire testing equipment, the number of which should be the same as the number of axles of the vehicle, and the number of the test modules 20 should be the same as the number of tires of the vehicle.

[0048] Furthermore, in other preferred embodiments of the utility model, a first support plate 103 is provided between the two test modules 20 arranged front and rear, and the top of the first support plate 103 is roughly flush with the roller 220. Roughly flush means that there is no obvious height difference between the first support plate 103 and the roller 220, so that the tire will not produce obvious bumps when running between the roller 220 and the first support plate 103.

[0049] Specifically, the vehicle under test is generally driven onto the test module 20, and there is no other structure that can carry the transition between the two first profile slides 101. Therefore, by designing the first support plate 103 between the two first support plates, the role of load-bearing transition can be played, so that the vehicle under test can be driven onto the test module 20 smoothly.

[0050] Here, the setting height of the first support plate 103 is to ensure that its top is roughly flush with the roller shaft 220. Specifically, a frame 40 is also provided above the two second profile slide grooves 102, and both ends of the first support plate 103 are connected to the frame 40 to ensure that it has a suitable height.

[0051] In addition, two second support plates 104 are provided at both ends of the bracket 10, and the test module 20 is arranged between the two second support plates 104, and the tops of the two second support plates 104 are roughly flush with the roller 220. Roughly flush means that there is no obvious height difference between the second support plate 104 and the roller 220, so that the tire will not produce obvious bumps when running between the roller 220 and the second support plate 104.

[0052] Here, the function of the second support plate 104 is similar to that of the first support plate 103, both of which are load-bearing transitions to ensure that the tested vehicle can smoothly drive onto and off the test module 20, and two of the second support plates 104 are arranged outside the two first profile chutes 101, such as at the front and rear ends of the device. Similarly, both ends of the second support plate 104 are also connected to the frame 40 to ensure that it has a suitable height so that its top is flush with the roller 220.

[0053] Furthermore, in other preferred embodiments of the present invention, the bracket 10 also includes two guide ramps 105, and the two guide ramps 105 are respectively arranged on both sides of the two second support plates 104, and one end of the guide ramp 105 is connected to the second support plate 104 by a hinge.

[0054] Specifically, since the test module 20 has a certain height, in order to facilitate the vehicle under test to be smoothly driven onto the test module 20 and smoothly driven down from the test module 20, the guide ramp 105 is respectively provided at the front and rear ends of the device, and the higher end of the guide ramp 105 is hinged on the outside of the second support plate 104, and the lower end of the guide ramp 105 is generally freely placed on the ground to facilitate guiding the vehicle under test.

[0055] When in use, the wheel under test passes through the guide ramp 105 and reaches the second support plate 104, and the linear drive device 2101 of the lifting platform 210 is controlled to rise to the level of the top of the ramp, that is, to the level of the second support plate 104, and then stops rising (such as Figure 1 As shown), the vehicle continues to move forward, passing through the first support plate 103, until the four tires stop just above the four bearing platforms 2102, supported by the four bearing platforms 2102, and then the linear drive device 2101 is controlled to descend (as shown). Figure 2As shown in the figure, the four tires synchronously descend to between the two rollers 220 and stop descending. Relying on the self-power of the tested vehicle, the tires and the rollers 220 roll relative to each other. According to different test scenarios, different types of rollers 220 are replaced. After the test is completed, the linear drive device 2101 is controlled to lift up, lift up the four tires, and the vehicle smoothly drives down the guide ramp 105 to the ground, and the entire test is completed.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model, rather than to limit them. Although the embodiments of the utility model are described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some of the technical features therein by equivalents.
