Therefore, the anti-skid property of the tires relative to the ground is of great significance. It is related to both the forward momentum brought by the rolling of the tires on the ground and the braking effect required when the tires brake. Therefore, the anti-skid property of automobile tires needs to be tested during the production process.

DETAILED DESCRIPTION

[0017] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0018] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0019] The present invention provides the following embodiments: Example 1 The embodiment of the present invention provides an intelligent detection device for the anti-skid property of automobile tires, such as Figure 1-12 As shown, it comprises: a support base 1, a rotating assembly 2 is arranged above the support base 1, a sliding detection assembly 4 is arranged below the rotating assembly 2, an angle structure 3 on the rotating assembly 2 is used to change the camber angle and toe angle of the tire, the sliding detection assembly 4 detects the side slip amount generated when the tire rolls on the roller 52 through the relative sliding between the rolling base 43 and the sliding rod 44, and a slippery element adding assembly 6 is arranged on one side of the sliding detection assembly 4; It also includes a calibration detection component 9, which is used to detect and calibrate the horizontality and accuracy of the sliding detection component 4.

[0020] The working principle and beneficial effects of the above technical solution are as follows: when the tire is tested for anti-skid performance, the tire is mounted on the rotating assembly 2, and the camber angle and toe angle of the tire are adjusted through the angle structure 3 to drive the tire to rotate. The tire is then brought into contact with the sliding detection assembly 4 by lifting and lowering, and drives the roller 52 of the sliding detection assembly 4 to rotate synchronously. When the tire skids during the rotation process, the amount of skidding is transferred to the roller 52, thereby causing a relative sliding distance between the rolling base 43 and the sliding rod 44. The anti-skid performance of the tire is determined by detecting the lateral displacement of the rolling base 43. In the testing process, water and ice are added to the sliding detection assembly 4 through the wet and slippery element adding assembly 6 to simulate the anti-skid performance of the tire on water- and snow-covered roads, and the horizontality and accuracy of the sliding detection assembly 4 after reset are checked by the calibration detection assembly 9. The present invention utilizes the rotating component 2 to simulate the rolling condition of the tire on the road surface, ensuring that the test conditions are close to the real scene. With the design of the angle structure 3, it can simulate the camber angle and the toe angle of the tire on the vehicle body, and can test the need to adjust the camber angle and the toe angle, and can realize the dynamic measurement of the tire side slip performance. The design of the sliding detection component 4 directly reflects the friction between the tire and the contact surface through the lateral offset or slip rate, quantifies the anti-skid performance, and realizes the automatic self-centering function after the test is completed. The design of the wet and slippery element adding component 6 simulates the wet and slippery environment by adding water and ice elements to the sliding detection component 4, thereby expanding the test range of the tire and being able to test the anti-skid ability of the tire under extreme wet and slippery conditions (such as water film, ice surface). The design of the calibration detection component 9 can detect and calibrate the levelness and accuracy of the sliding detection component 4 to avoid errors in the detection results caused by errors in the levelness and accuracy of the sliding detection component 4.

[0021] Example 2 On the basis of Example 1, the rotating component 2 includes a supporting channel steel 21, the bottoms of the two supporting channel steels 21 are symmetrically bolted to the supporting base 1, the tops of the two supporting channel steels 21 are bolted to a top cover 22, a hydraulic support 23 is bolted between the two supporting channel steels 21, the working end of the hydraulic support 23 is bolted to a mounting platform 24, the mounting platform 24 is slidably connected between the two supporting channel steels 21, a rotating motor 25 is bolted to the mounting platform 24, and the angle structure 3 is connected to the output end of the rotating motor 25.

[0022] The angle structure 3 includes a mounting disc 31, one side of the mounting disc 31 is rotatably connected to the mounting platform 24, the mounting disc 31 is key-connected to the output end of the rotating motor 25, the other side of the mounting disc 31 is fixedly connected to a transverse rotating seat 32, the center of the transverse rotating seat 32 is rotatably connected to a cross fixing plate 33, the transverse rotating seat 32 is symmetrically provided with two sets of limiting gaps 34, one side of the cross fixing plate 33 is symmetrically hinged with a connecting rod 35, the other side of the cross fixing plate 33 is fixedly connected with a longitudinal rotating seat 36, the left and right sides of the cross fixing plate are provided with limiting gaps 37, the longitudinal rotating seat 36 is rotatably connected with a mounting chuck 38, one side of the mounting chuck 38 is symmetrically hinged with a connecting rod 39, the other ends of the two connecting rods 35 are both slidably connected in the limiting gap 34, the other ends of the two connecting rods 39 are slidably connected in the limiting gap 37, and the two connecting rods 35 and the two connecting rods 39 are both threadedly connected with positioning nuts 310.

[0023] The working principle and beneficial effects of the above technical solution are as follows: after the tire bolt is installed on the mounting chuck 38, the retaining nut 310 on the connecting rod 1 35 is loosened first, and then the two connecting rods 1 35 are pulled to make the cross fixing plate 33 rotate horizontally around the lateral rotating seat 32, thereby adjusting the camber angle of the tire, and after the adjustment is completed, the retaining nut 310 on the connecting rod 1 35 is tightened again, and then the retaining nut 310 on the connecting rod 2 39 is loosened, and the mounting chuck 38 is rotated vertically around the longitudinal rotating seat 36 by pulling the two connecting rods 2 39, thereby adjusting the toe angle of the tire, and after the adjustment is completed, the retaining nut 310 on the connecting rod 2 39 is tightened again, and then the rotating motor 25 is started, and the rotating motor 25 drives the mounting disc 31 to rotate, thereby causing the tire to rotate, and during the rotation of the tire, the hydraulic support 23 gradually descends, causing the tire to gradually contact the sliding detection component 4; The present invention utilizes connecting rod 1 35 and connecting rod 2 39 to adjust the camber angle and toe angle of the tire. This design allows step-by-step operation to avoid mutual interference between parameters, thereby improving the adjustment accuracy. The design of the limiting gap 1 34 and the retaining nut 310 can ensure that there is sufficient adjustment space and the stability of connecting rod 1 35 and connecting rod 2 39. At the same time, the design of the supporting channel steel 21 and the mounting platform 24 can ensure that the hydraulic support 23 can not only realize the lifting work, but also provide stability in supporting the rotating motor 25.

[0024] Example 3 On the basis of Example 1, the sliding detection component 4 includes an upper sliding detection groove 41 and a lower sliding detection groove 42. The upper sliding detection groove 41 is arranged on the top cover 22, and the lower sliding detection groove 42 is arranged on the support base 1. A rolling base 43 is provided in the upper sliding detection groove 41 and the lower sliding detection groove 42. The rolling base 43 is slidably connected to a plurality of sliding rods 44. The plurality of sliding rods 44 are respectively bolted to the support base 1 and the top cover 22. A plurality of compression elastic parts 45 are sleeved on the sliding rods between the rolling base 43 and the support base 1 and the rolling base 43 and the top cover 22, and a rolling structure 5 is provided on the rolling base 43.

[0025] The rolling structure 5 includes a rolling pulley 51, and several rolling pulleys 51 are bolted to the rolling base 43 at the upper and lower ends respectively. A roller 52 is arranged between the rolling pulleys 51, and belt sleeves 53 are nested on both sides of the outer ring of the roller 52. The belt sleeves 53 are slidably connected to the rolling pulley 51. Several buckles 54 are fixedly connected to the inner ring of the roller 52, and rolling contact materials 55 are nested and connected to the several buckles 54.

[0026] The working principle and beneficial effects of the above technical solution are as follows: when the tire contacts the roller 52 in a rotating state, the tire drives the roller 52 to rotate under the action of friction. When the roller 52 rotates, the belt sleeve 53 on the roller 52 rotates synchronously on the several rolling pulleys 51 of the rolling base 43 at the upper and lower ends. At the same time, the sliding rods 44 in the upper sliding detection groove 41 and the lower sliding detection groove 42 support the rolling base 43 to ensure the stability of the rolling base 43 in the vertical direction. Due to the camber angle and toe angle of the tire, the tire will have a lateral slip during the rolling process. Therefore, when the tire drives the roller 52 to rotate, the lateral slip generated by the tire is transmitted to the roller 52 under the action of friction, so that the roller 52 drives the rolling base 43 to slide along the sliding rod 44 to generate a side sliding distance. When the rolling base 43 slides, it squeezes the compression elastic member 45. Several rolling contact materials 55 on the roller 52 are used to simulate the real road environment, and the buckle 54 fixes the rolling contact material 55. The present invention utilizes a rolling pulley 51 and a roller 52 to simulate the rolling of a tire in a real environment, and transfers it to the roller 52. By detecting the lateral displacement of the rolling base 43 under the roller 52, the side slip performance of the tire is obtained. This design can directly quantify the side slip distance and intuitively display the anti-skid property of the tire. The design of the sliding rod 44 and the compression elastic member 45 enables the rolling base 43 to have a self-resetting function without the need for manual auxiliary reset. At the same time, the design of the rolling contact material 55 can reproduce a variety of road conditions, making the test closer to actual road conditions.

[0027] Example 4 On the basis of Example 1, the slippery element adding component 6 includes a wetting roller 61, which is rotatably connected to a water distribution pipe 62, which is rotatably connected to a rotating connector 63. The input end of the rotating connector 63 is connected to an electric valve 64 through a pipeline. A baffle 65 is installed on the electric switch of the electric valve 64. The baffle 65 and the water distribution pipe 62 abut against each other. The electric valve 64 is bolted to a rolling base 43. A compression elastic member 66 is provided between the water distribution pipe 62 and the rolling base 43. The input end of the electric valve 64 is connected to a water supply pipe, and a freezing structure 7 is provided under the water distribution pipe 62.

[0028] The freezing structure 7 includes a vortex chamber 71, in which a vortex ring 72 is provided. A nested tube 73 is passed through and fixedly connected to one end of the vortex ring 72, and a plurality of guide grooves 74 are arranged in a ring at the other end of the vortex ring 72. A heat pipe 75 is fixedly connected to one end of the vortex chamber 71, and an end cover 76 is bolted to the other end of the vortex chamber 71. The end cover 76 is key-connected to the vortex ring 72, and a cold pipe 77 is passed through and fixedly connected to the end cover 76. The cold pipe 77 is sleeved on the nested tube 73. An air intake pipe 78 is passed through and fixedly connected to the vortex chamber 71. The air intake pipe 78 and the vortex ring 72 correspond to each other, and the air intake pipe 78 is connected to the air pump. A conversion mechanism 8 is provided on the vortex chamber 71.

[0029] The conversion mechanism 8 includes a suspension rod 81, the top of which is bolted to the rolling base 43, a pod 82 is bolted to the bottom of the suspension rod 81, a connecting plate 83 is rotatably connected in the pod 82, one end of the connecting plate 83 is bolted to the vortex chamber 71, and the other end of the connecting plate 83 is provided with a sliding groove 84, a rotating pressure rod 85 is slidably connected in the sliding groove 84, a limiting block 86 is fixedly connected to the rotating pressure rod 85, the other end of the rotating pressure rod 85 passes through and is rotatably connected to a fixed end cover 87, the fixed end cover 87 is bolted to the pod 82, a compression elastic member 88 is provided between the limiting block 86 and the connecting plate 83, and the limiting block 86 and the fixed end cover 87 are key-connected.

[0030] The working principle and beneficial effects of the above technical solution are as follows: when it is necessary to add a slippery element to the sliding detection component 4, the electric valve 64 is started, and the electric valve 64 is started and drives the baffle rod 65 to rotate at the same time. When the baffle rod 65 rotates, the water distribution pipe 62 and the wetting roller 61 are pushed to rotate along the rotating connector, so that the wetting roller 61 contacts the rolling contact material 55 on the roller 52. Subsequently, driven by the roller 52, the wetting roller 61 rotates relative to the roller, and the rolling contact material 55 is soaked with water, so that the tire simulates rain conditions when rotating on the roller. When the roller 52 needs to add ice elements, the air pump is started to deliver compressed air to the inlet pipe. After the compressed air enters the vortex chamber 71, it enters the heat pipe 75 from the guide groove 74 of the vortex ring 72. Due to the rotating structure of the guide groove 74, the compressed air advances along the inner wall of the heat pipe 75 in a vortex shape, and the compressed air is in contact with the air at the center of the heat pipe 75. The mutual friction generates reverse vortex gas, which enters the cold pipe 77 through the center of the vortex ring 72. The inner and outer vortex gases rub against each other to exchange heat, making the outer vortex hotter and the inner vortex colder. After the inner vortex is output from the cold pipe 77, it freezes the water flow of the rolling contact material 55 of the roller 52, so that ice is generated on the roller 52, simulating the rolling of the tire on the ice surface. When it is necessary to thaw the rolling contact material 55, the rotating pressure rod 85 is pushed to slide along the sliding groove 84. The limit block 86 on the rotating pressure rod 85 is connected to the contact key of the fixed end cover 87 and compresses the compression elastic member 3 88. Then, the rotating pressure rod 85 is twisted and the rotating pressure rod 85 drives the connecting plate 83 to rotate. The rotation of the connecting plate 83 causes the vortex chamber 71 to rotate, thereby causing the cold pipe 77 and the heat pipe 75 to rotate 180 degrees. The heat pipe 75 uses the hot air flow to thaw the rolling contact material 55. The present invention utilizes a wetting roller 61 to wet the drum 52 to simulate a rainy day environment. This design can increase the anti-skid test of the tire in extreme environments, and further improve the accuracy and comprehensiveness of the tire anti-skid detection. The design of the electric valve 64 and the baffle 65 can ensure that the drum 52 is wetted only when the electric valve 64 is opened, thereby avoiding idling of the wet drum 52. The design of the vortex chamber 71 and the vortex ring 72 can generate hot air flow and cold air flow, which can freeze the drum 52 with the cold air flow and defrost the drum 52 with the hot air flow. At the same time, the design of the connecting disk 83 and the rotating pressure rod 85 can rotate the vortex chamber 71 180°. This design can facilitate the operator to remotely operate the vortex chamber 71 to avoid damage to the human body caused by cold air or hot air.

[0031] Example 5 On the basis of Example 1, the calibration detection component 9 includes a level 91, which is bolted to the sides of the two rolling bases 43, and the four corners of the bottom surface of the support base 1 are fixedly connected to the lifting bolts 92, and the lifting bolts 92 are threadedly connected to the anchor nut 93. The bottom of the anchor nut 93 is rotatably connected to a pad 94, and a tooth groove 95 is provided on the outer side of the anchor nut 93. The side of the anchor nut 93 is rotatably connected to a rotating ring 96, and the bottom of the rotating ring 96 is hingedly connected to a power-assisting rod 97, which cooperates with the tooth groove 95, and a mounting groove 98 is provided on the side of the rotating ring 96. A spacing calibration structure 10 is provided below the level 91.

[0032] The spacing calibration structure 10 includes a center rod 101, which is bolted to both sides of the rolling base 43, and the other end of the center rod 101 is symmetrically fixedly connected to an infrared sensor 102. Distance measuring rods 103 are provided on both sides of the center rod 101, and a reflection plate 104 is installed on the distance measuring rod 103. The distance measuring rod 103 is hinged to the support base 1, and the side of the distance measuring rod 103 is hinged to a folding rod 105, and the other end of the folding rod 105 is hinged to the support base 1.

[0033] The working principle and beneficial effects of the above technical solution are as follows: when the detection equipment is performing detection, the operator first checks the levelness of the level ruler 91. When the level ruler 91 is not level, the rolling base 43 is tilted, which may cause errors when detecting the tire's anti-skid performance. Therefore, the power-assisting rod 97 is rotated to make it rotate from the mounting groove 98 to the horizontal, and the short end of the power-assisting rod 97 is embedded in the tooth groove 95. Then, the power-assisting rod 97 is pushed to make the rotating ring 96 and the anchor nut 93 rotate. The rotation of the anchor nut 93 makes the lifting bolt 92 screw in or out of the anchor nut 93, thereby pushing the support base 1 to lift. After rotating to a certain angle, the power-assisting rod 97 is rotated to make it disengage from the tooth groove 95. Then Push the assist rod 97 in the opposite direction to drive the rotating ring 96 to rotate along the anchor nut 93, then rotate the assist rod 97 again to embed it into the tooth groove 95, repeat the above operation until the adjusted level rulers 91 at the four corners of the support base 1 are horizontal, then check the accuracy of the rolling base 43, rotate the distance measuring rod 103 from the horizontal state to the vertical state and support it with the folding rod, and judge whether the rolling base 43 is accurate by whether the distance between the infrared sensor 102 on both sides of the center rod 101 and the two reflective plates 104 is equal. When the distance between the two is not equal, inspect the sliding detection component 4. After the inspection is completed, fold the folding rod to rotate the distance measuring rod 103 to the horizontal state; The present invention uses the horizontality to judge whether the rolling base 43 is horizontal. The design can intuitively understand the horizontality of the sliding detection component 4, avoid the error of the detection result caused by the tilt of the rolling base 43, and the design of the power rod 97, the rotating ring 96 and the anchor nut 93 can make the power rod 97 repeatedly rotate to realize the lifting and lowering of the support base 1, which is convenient for the operator to operate. At the same time, the design of the ranging rod 103, the reflecting plate 104 and the infrared sensor 102 can detect the left and right relative sliding error of the rolling base 43 with the ranging rod 103 as the standard, which has the advantages of high efficiency and speed.
