Description

Technical Field

[0001] The present invention relates to the technical field of tire thermal expansion coefficient detection devices, and particularly relates to a motorcycle tire expansion detection device based on laser scanning. Background Art

[0002] A motorcycle wheel includes a wheel hub, a wheel hub rotating shaft, a tire, etc. When the tire is filled with air pressure and heated, it will expand. Its thermal expansion is mainly caused by the following factors: 1. Friction heat generation: Heat is generated by the friction between the tire and the ground, which is more obvious especially when driving at high speed or braking suddenly; 2. Ambient temperature: High temperature weather or high road surface temperature will exacerbate the rise in tire temperature; 3. Tire material: Materials such as rubber will expand at high temperatures, resulting in an increase in tire volume; 4. Internal air pressure: The increase in temperature will cause the internal air pressure of the tire to increase, further exacerbating the expansion.

[0003] The thermal expansion of motorcycle tires will not only cause the change of tire shape, affecting the grip and handling stability, but excessive expansion will also increase the probability of tire blowout; at the same time, the uneven expansion of the tire will accelerate tire wear and shorten the service life. Therefore, it is very necessary to conduct thermal expansion detection on motorcycle tires after they leave the factory. However, the existing detection methods mostly start from the side, such as tire pressure detection, which can only monitor the air pressure. Currently, there is a lack of special detection devices and it cannot directly reflect the change of the thermal expansion coefficient of the tire caused by temperature change. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle tire expansion detection device based on laser scanning. Through the rotating bucket screwed inside the main housing assembly, the introduction of the wheel hub and tire to be detected can be realized. At the same time, the rotation action of the rotating bucket itself, combined with the use of the rotation drive module, the pressure roller assembly and the thermal circulation assembly, can form the detection of the thermal expansion coefficient of the tire in different temperature environments under the rotation state of the tire by using the laser scanning probe.

[0005] The purpose of the present invention is achieved by such a technical solution. A motorcycle tire expansion detection device based on laser scanning includes a main housing assembly, a rotating bucket assembly, a rotation drive module, a pressure roller assembly and a thermal circulation assembly. The main housing assembly includes a laser scanning probe. The rotating bucket assembly includes a rotating bucket, a servo electric cylinder and a driving roller. The rotation drive module includes a driving large gear. The pressure roller assembly includes a passive safety roller. The thermal circulation assembly includes an outer circulation pipe and an air suction circulation fan.

[0006] An object inlet channel is connected to one side of the main body of the main housing assembly. The laser scanning probe is symmetrically installed on one side of the top inside the main body of the main housing assembly. The main body of the servo electric cylinder is screwed on the other side inside the main body of the main housing assembly. One end outside of the rotating bucket is screwed to the lower end inside the object inlet channel. The telescopic rod of the servo electric cylinder is screwed to the lower part of the other end of the rotating bucket. The driving roller is screwed to the upper part of the other end of the rotating bucket. Bottom rotating rollers are arranged and screwed at the inner bottom end of the rotating bucket.

[0007] The driving large gear is inserted and fixed at the outer end of the rotating shaft of the driving roller. A rotatable driving gear is installed on one side of the top end of the main body of the servo electric cylinder. A follower frame is also fixed on one side of the main body of the servo electric cylinder. The passive safety roller is arranged and rotatably connected at the head end of the follower frame. When the rotation of the rotating bucket drives the hub and the tire to be detected to be imported to a position where they are in rolling contact with both the bottom rotating roller and the driving roller, as the rotating bucket continues to rotate, it can drive the driving gear to mesh with the driving large gear, and the passive safety roller is moved to a position where it maintains a certain distance from the outside of the tire.

[0008] One end inlet of the outer circulation winding pipe is connected to the lower end on one side of the main body of the main housing assembly, and the other end outlet is connected to the upper end on the other side of the main body of the main housing assembly. An electric heating mechanism is installed in the main body of the outer circulation winding pipe. The air suction circulation fan is coaxially fixed at one end of the driving gear.

[0009] The usage process formed by the technical solution of the present invention is as follows:

[0010] When the rotating bucket is tilted towards the object inlet channel, the inlet of the rotating bucket extends beyond the object inlet channel, facilitating the placement of the hub and the tire into the internal channel of the rotating bucket.

[0011] After the hub and the tire are placed into the inlet of the rotating bucket, the servo electric cylinder is started. The telescopic rod of the servo electric cylinder extends, and through the rotational connection between the head of the telescopic rod of the servo electric cylinder and the lower part of the other end of the rotating bucket, it can drive the rotating bucket to rotate towards the inside of the main body of the main housing assembly, driving the hub and the tire to roll towards the driving roller.

[0012] After the outside of the tire comes into contact with both the driving roller and the bottom rotating roller, as the rotating bucket continues to rotate towards the inside of the main body of the main housing assembly, the driving large gear can be made to form a cooperative drive with the driving gear.

[0013] And synchronously, when the rotating bucket rotates to the position where the driving large gear meshes with the driving gear, the passive safety roller is also just moved to a position at a certain distance from the outside of the tire.

[0014] Through the cooperative drive formed by the automatically rotatable driving gear and the driving large gear, it can drive the driving roller to rotate actively. By using the frictional contact formed between the driving roller and the outside of the tire, the hub and the tire can be driven to roll and rotate between the driving roller, the bottom rotating roller, and the passive safety roller.

[0015] By starting the electric heating mechanism connected to the outer circulation winding pipe, heat can be generated in the internal pipeline of the outer circulation winding pipe. And while the cooperative drive is formed between the driving gear and the driving large gear, the air suction circulation fan is just facing the inlet of the outer circulation winding pipe.

[0016] When the driving gear drives the tire to roll and rotate through the cooperation transmission formed with the large driving gear, the rotation of the air suction circulation fan can also form the air circulation power inside the external circulation around the pipe, so that the heated air inside the external circulation around the pipe is circulated and blown into the main body of the main housing assembly, maintaining a certain temperature environment inside the main body of the main housing assembly;

[0017] The change in the temperature environment will cause the air pressure of the tire to change, resulting in the thermal expansion of the tire. By using the automatic scanning of the laser scanning probe, not only can the shape profile of the tire before the temperature rises be obtained, but also the shape profile of the tire after the temperature rises to a certain value can be scanned, so as to be able to test the thermal expansion coefficient of different tires adapting to temperature changes.

[0018] By adopting the above technical solutions, the beneficial effects of the present invention are as follows:

[0019] (1) In the present invention, a swivel bucket is screwed at the inner lower end of the object inlet channel connected inside the main body of the main housing assembly. Combining the channel formed inside the swivel bucket itself, as the servo electric cylinder drives the swivel bucket to form different rotation states, the channel inside the swivel bucket can form different inclination angles. Thus, when the swivel bucket inclines towards one side of the object inlet channel, it is convenient to put the hub to be detected into the channel inside the swivel bucket. When the swivel bucket rotates towards the inside of the main housing assembly, under the action of gravity, the tire can roll from the inlet end of the swivel bucket to the position to be detected in contact with the driving roller. The structure is simple and the operation is convenient;

[0020] (2) After the swivel bucket rotates to the outside of the tire and contacts the driving roller, as the swivel bucket continues to rotate towards the inside of the main housing assembly, not only can the large driving gear at the outer end of the driving roller shaft form a cooperation with the driving gear that can automatically rotate, but also the passive safety roller can move to a position maintaining a certain distance from the outside of the tire, so as to drive the tire to roll and rotate within a certain amount of play, and it is also convenient to adapt to the change of the thermal expansion of the tire caused by the temperature rise;

[0021] (3) When the driving gear rotates automatically in the present invention, it can also drive the rotation of the air suction circulation fan. The rotation of the air suction circulation fan cooperates with the electric heating mechanism inside the external circulation around the pipe, and can form a cyclic heating for raising the temperature of the internal space of the main housing assembly, which is energy-saving and environment-friendly.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0045] As Figures 1-13A motorcycle tire inflation detection device based on laser scanning is shown. On one side of the main body of the main housing assembly 1, an object inlet channel 102 is connected. Laser scanning probes 104 are symmetrically installed on one side of the top inside the main body of the main housing assembly 1. The main body of the servo electric cylinder 207 is rotatably connected to the other side inside the main body of the main housing assembly 1. A channel for facilitating the rolling of the tire is provided inside the rotating bucket 203. One end outside of the rotating bucket 203 is rotatably connected to the lower end inside the object inlet channel 102. The telescopic rod of the servo electric cylinder 207 is rotatably connected to the lower part of the other end of the rotating bucket 203. The driving roller 209 is rotatably connected to the upper part of the other end of the rotating bucket 203. The bottom rotating rollers 213 are arranged and rotatably connected to the inner bottom end of the rotating bucket 203, which can form different rotation angles of the rotating bucket 203, and guide the hub and tire to be detected to a position where they are in rolling contact with both the bottom rotating rollers 213 and the driving roller 209.

[0046] The driving large gear 301 is inserted and fixed to the outer end of the rotating shaft of the driving roller 209. A rotatable driving gear 303 is installed on one side of the top of the main body of the servo electric cylinder 207. A follower frame 401 is also fixed on one side of the main body of the servo electric cylinder 207. The passive safety rollers 402 are arranged and rotatably connected to the head end of the follower frame 401. When the rotation of the rotating bucket 203 guides the hub and tire to be detected to a position where they are in rolling contact with both the bottom rotating rollers 213 and the driving roller 209, as the rotating bucket 203 continues to rotate, it can drive the driving gear 303 to mesh with the driving large gear 301, and the passive safety rollers 402 are moved to a position where they maintain a certain distance from the outside of the tire.

[0047] Moreover, the driving roller 209, the bottom rotating rollers 213, and the passive safety rollers 402 that are in rolling contact with the outside of the tire can cover more than half of the tire, enabling the tire to freely roll between the driving roller 209, the bottom rotating rollers 213, and the passive safety rollers 402 without slipping out.

[0048] The purpose of maintaining a certain distance between the passive safety rollers 402 and the outside of the tire is to enable the tire to roll and rotate within a reasonable wobble range and to adapt to the thermal expansion changes of the tire during subsequent detection.

[0049] And the driving roller 209, the bottom rotating rollers 213, and the passive safety rollers 402 are all of a curved surface structure that fits the outside of the tire.

[0050] And since the driving roller 209, the bottom rotating rollers 213, and the passive safety rollers 402 form a certain fixed contour, this device is only applicable to the detection of tires of a certain specification size.

[0051] One end inlet of the outer circulation bypass pipe 501 is connected to the lower end of one side of the main housing assembly 1, and the other end outlet is connected to the upper end of the other side of the main housing assembly 1. An electric heating mechanism is installed in the main body of the outer circulation bypass pipe 501. The suction circulation fan 505 is coaxially fixed to one end of the driving gear 303. When the driving gear 303 meshes with the driving large gear 301, the suction circulation fan 505 is just opposite to the inlet of the outer circulation bypass pipe 501.

[0052] The working principle is as follows:

[0053] The interior of the main body of the main housing assembly 1 provides a space for detecting the tire in a certain temperature environment.

[0054] The hub and tire to be detected can enter the interior of the main body of the main housing assembly 1 through the inlet passage 102.

[0055] And before detection, the tire is inflated according to the test conditions and has a set value of air pressure inside.

[0056] When the swivel bucket 203 is tilted towards the inlet passage 102, the inlet of the swivel bucket 203 extends outside the inlet passage 102, facilitating the placement of the hub and tire into the inner passage of the swivel bucket 203.

[0057] After the hub and tire are placed into the inlet of the swivel bucket 203, the servo electric cylinder 207 is started. The telescopic rod of the servo electric cylinder 207 extends, and through the swivel connection between the head of the telescopic rod of the servo electric cylinder 207 and the lower part of the other end of the swivel bucket 203, the swivel bucket 203 can be driven to rotate towards the interior of the main body of the main housing assembly 1, driving the hub and tire to roll towards the direction of the driving roller 209.

[0058] And after the outer surface of the tire comes into contact with both the driving roller 209 and the bottom rotating roller 213, by continuously rotating the swivel bucket 203 towards the interior of the main body of the main housing assembly 1, the driving large gear 301 and the driving gear 303 can be made to form a cooperative drive.

[0059] And synchronously, when the swivel bucket 203 rotates to the position where the driving large gear 301 meshes with the driving gear 303, the passive safety roller 402 is also just moved to a certain position away from the outer surface of the tire.

[0060] At this time, the outer surface of the tire is rollingly clamped between the driving roller 209, the bottom rotating roller 213, and the passive safety roller 402.

[0061] Through the cooperative drive formed by the automatically rotatable driving gear 303 and the driving large gear 301, the driving roller 209 can be driven to rotate actively. By utilizing the frictional contact formed between the driving roller 209 and the outer surface of the tire, the hub and tire can be driven to roll and rotate between the driving roller 209, the bottom rotating roller 213, and the passive safety roller 402.

[0062] And since the passive safety roller 402 actually maintains a certain distance from the outer surface of the tire, the tire can roll and rotate within a reasonable amount of play;

[0063] The purpose of performing the thermal expansion detection after the tire rolls and rotates is to better simulate the change in the internal air pressure of the tire caused by the external temperature change in the actual driving environment; another purpose is to facilitate the comprehensive scanning and detection of the changes in the tire by the laser scanning probe 104 fixed at the top end inside the main housing assembly 1 while the tire rolls and rotates;

[0064] By starting the electric heating mechanism connected to the outer circulation pipe 501, heat can be generated in the internal pipeline of the outer circulation pipe 501, and while the driving gear 303 and the driving large gear 301 form a cooperative drive, the air suction circulation fan 505 is just facing the inlet of the outer circulation pipe 501;

[0065] When the driving gear 303 drives the tire to roll and rotate through the cooperative drive formed with the driving large gear 301, the rotation of the air suction circulation fan 505 can also form the air circulation power inside the outer circulation pipe 501, so that the heated air inside the outer circulation pipe 501 is circulated and blown into the main body of the main housing assembly 1 to maintain a certain temperature environment inside the main body of the main housing assembly 1;

[0066] The change in the temperature environment will cause the air pressure of the tire to change, resulting in the thermal expansion of the tire. By using the automatic scanning of the laser scanning probe 104, not only can the shape contour of the tire before the temperature rises be obtained, but also the shape contour of the tire after the temperature rises to a certain value can be scanned, so as to be able to test the thermal expansion coefficient of different tires adapting to temperature changes;

[0067] The thermal expansion coefficient of a tire is a regular coefficient in which its geometric characteristics change with the change of temperature under the action of the thermal expansion and contraction effect. When the temperature changes by 1 degree Celsius, it is the ratio of the change in its geometric size to its size at a certain temperature;

[0068] Assume that at a certain temperature, the volume of the tire scanned by the laser scanning probe 104 is V1, and after the temperature changes by 1 degree Celsius, the cross-sectional area of the outer shape of the tire scanned by the laser scanning probe 104 is V2. Then, (V2 - V1) / V1 is the thermal expansion coefficient of the tire at this time;

[0069] After the test is completed, start the servo electric cylinder 207 again. After lifting the rotating bucket 203 to a position inclined towards the loading channel 102, under the action of gravity, the wheel hub and the tire can roll outwards from the loading channel 102.

[0070] The specific structures of the main housing assembly 1 and the rotating bucket assembly 2 are as Figure 2 、 Figure 3 、Figure 4 and Figure 5 As shown in Figure 5 , the incoming object channel 102 is connected to one side of the cavity wall of the outer housing 101, and the laser scanning probe 104 is symmetrically installed and fixed at the top of the inner cavity on one side of the outer housing 101;

[0071] A temperature sensor 105 is also installed and fixed at the upper end of one side of the inner cavity of the outer housing 101 for real-time monitoring of the temperature change in the internal space of the outer housing 101;

[0072] A control center 103 is installed and fixed on the outer main surface of the outer housing 101, which can automatically control the electric control components in the device;

[0073] The side cover 201 is fixedly connected to the other side of the cavity wall of the outer housing 101. The electric cylinder fixing seat 205 is fixedly installed on the inner side surface of the side cover 201. The main body of the servo electric cylinder 207 is rotatably connected to the electric cylinder fixing seat 205, and the side cover 201 can be detached from the outer housing 101 to facilitate the installation of the servo electric cylinder 207;

[0074] Rotary bucket seats 202 are fixedly installed at both lower ends of the incoming object channel 102. Rotary shafts 204 are symmetrically fixed on the outer side of one end of the rotary bucket 203, and the rotary shafts 204 on the same side are rotatably connected in the rotary bucket seats 202;

[0075] The lower part of the other end of the rotary bucket 203 is fixedly provided with an electric cylinder rotary seat 206, and the head of the telescopic rod of the servo electric cylinder 207 is rotatably connected to the electric cylinder rotary seat 206;

[0076] And ventilation grilles are provided on both sides of the main body of the rotary bucket 203 to facilitate air circulation;

[0077] The driving roller seat 208 is fixedly connected to the upper part of the other end of the rotary bucket 203, and the rotating shaft of the driving roller 209 is rotatably connected to the driving roller seat 208;

[0078] Slow-moving racks 210 are fixedly connected to both sides of the top of the rotary bucket 203. Slow-moving gears 211 are fixed to both ends of the hub rotating shaft. Inclined surfaces are provided on both sides of the slow-moving rack 210, so that as the rotary bucket 203 tilts towards the inner cavity of the outer housing 101 and the hub and tire roll from the channel inside the rotary bucket 203 towards the driving roller 209, the slow-moving gear 211 can roll from the inclined surface provided on one side of the slow-moving rack 210 to the position where it engages with the tooth body of the slow-moving rack 210. That is, after the tire rolls to the position where the slow-moving gear 211 engages with the slow-moving rack 210, it can move slowly from the inlet of the rotary bucket 203 towards the driving roller 209 under the guidance of the cooperation formed by the slow-moving rack 210 and the slow-moving gear 211, eliminating the problem of excessive falling potential energy when the tire freely rolls in the internal channel of the rotary bucket 203 and bouncing back after contacting the driving roller 209;

[0079] And before the outside of the tire contacts the driving roller 209, the slow-moving gear 211 has disengaged from the slow-moving rack 210, which can prevent the cooperation formed by the slow-moving gear 211 and the slow-moving rack 210 from interfering with the rotation of the tire in the detection state;

[0080] After the detection is completed, as the tipping bucket 203 tilts towards the inlet passage 102 side, and the slow-moving gear 211 forms a cooperation with the tooth body of the slow-moving rack 210 through the inclined surface opened on the other side of the slow-moving rack 210, the tire can slowly exit outside the tipping bucket 203;

[0081] And the tilting angle of the tipping bucket 203 itself is sufficient to support, under the action of gravity, the slow-moving gear 211 and the slow-moving rack 210 to form a cooperative drive;

[0082] An inclined guide surface 214 is connected to the bottom entrance of the tipping bucket 203, a straight-through guide surface 215 is connected between the bottom end of the tipping bucket 203 and the inclined guide surface 214, a bottom roller seat 212 is fixedly connected in the straight-through guide surface 215, and bottom rotating rollers 213 are arranged to rotate in the bottom roller seat 212;

[0083] And the included angle between the inclined guide surface 214 and the straight-through guide surface 215 is an obtuse angle. By setting the inclined guide surface 214 at the entrance of the tipping bucket 203, the purpose is to facilitate the placement of the tire to be detected after the tipping bucket 203 tilts in place towards the inlet passage 102 side, so that after the tire is placed in the space between the top surface of the inclined guide surface 214 and the tipping bucket 203, it will not retreat due to its own gravity.

[0084] The specific structures of the rotation drive module 3 and the pressing roller assembly 4 are as Figure 6 、 Figure 7 、 Figure 8 and Figure 9 shown. The drive motor 302 is fixedly installed on one side of the top end of the main body of the servo cylinder 207, and the drive gear 303 is inserted and fixed in the rotating shaft of the drive motor 302. The purpose of fixedly connecting the drive motor 302 to the servo cylinder 207 instead of fixedly installing it on the inner cavity side wall of the outer housing 101 is that after the drive motor 302 and the servo cylinder 207 are fixed, the movements of the drive gear 303 and the driving large gear 301 can be regarded as moving based on the same component, thereby reducing the problem of poor accuracy caused by the increase of the relative reference;

[0085] The side connecting frame 403 is fixedly connected to one side of the head end of the follower frame 401, the rotational speed sensor 404 is fixedly installed in the side connecting frame 403, and the position of the rotational speed sensor 404 is directly opposite to the position of the wheel hub. Cooperating with the feedback element pre-fixed in the wheel hub, the rotational speed of the tire can be monitored in real time to automatically control the rotational speed provided by the drive motor 302.

[0086] The specific structure of the thermal cycle component 5 is as Figure 10 andFigure 11 As shown, the inlet end of the outer circulation bypass pipe 501 is connected to the lower end of one side wall of the outer shell 101, and the outlet end is connected to the upper end of the other side wall of the outer shell 101, which can form a non-opposite distribution of the inlet end and the outlet end of the outer circulation bypass pipe 501 in the inner cavity of the outer shell 101, improving the circulation efficiency of the heated air in the inner cavity of the outer shell 101;

[0087] An inner support 502 is also fixedly installed on the inner cavity side wall of the outer shell 101, and the outer surface of the inlet end of the outer circulation bypass pipe 501 is fixedly clamped with the inner support 502, which can improve the connection safety between the outer circulation bypass pipe 501 and the outer shell 101;

[0088] A heating pipe 503 is connected in the main pipeline of the outer circulation bypass pipe 501, and the heating wire 504 is installed inside the heating pipe 503, which can heat the air flowing through.

[0089] Preferably, as Figure 12 and Figure 13As shown in the figure, a safety revolving door assembly 6 is also installed at the position where the incoming object channel 102 is connected to the outer surface of the outer housing 101, which is used to open and close the incoming object channel 102. The opening and closing rotating base 601 is located directly above the incoming object channel 102 and is fixedly installed in the side wall of the outer housing 101. The inner top ends of each group of opening and closing fans 602 are fixedly connected with an opening and closing shaft 603, and the opening and closing shaft 603 is rotatably connected with the opening and closing rotating base 601. The inner end of one group of opening and closing shafts 603 is inserted and fixed with an opening and closing gear 604 and an opening and closing bevel gear 605. The transfer bevel gear 608 is engaged on one side of the opening and closing bevel gear 605. A transfer seat 606 is fixed on the outer top surface of the incoming object channel 102, and a transfer shaft 607 is rotatably connected in the transfer seat 606. The transfer bevel gear 608 is inserted and fixed at one end of the transfer shaft 607, and a transfer toothed belt wheel 609 is inserted and fixed at the other end of the transfer shaft 607. The outer end of one group of swivel bucket shafts 204 is inserted and fixed with a rotating toothed belt wheel 610, and a toothed belt 611 is sleeved and installed between the transfer toothed belt wheel 609 and the rotating toothed belt wheel 610. It can be made that with the tilting action of the swivel bucket 203 based on the swivel bucket shaft 204, the opening and closing fans 602 can form opening and closing actions synchronously. That is, when the swivel bucket 203 and the swivel bucket shaft 204 rotate towards the incoming object channel 102, the toothed belt 611 can form a cooperative drive between the rotating toothed belt wheel 610 and the transfer toothed belt wheel 609, so that the transfer bevel gear 608 rotates in the same direction as the swivel bucket shaft 204. The opening and closing bevel gear 605 and the transfer bevel gear 608 form a cooperative drive, which can drive two mutually engaged opening and closing gears 604 to rotate synchronously, driving the opening and closing fans 602 to form an opening action. On the contrary, when the swivel bucket 203 rotates towards the inner cavity side of the outer housing 101, the opening and closing fans 602 form a closing action. And the rotation action of the swivel bucket 203 and the opening and closing action of the opening and closing fans 602 will not interfere with each other. That is, before the swivel bucket 203 rotates to the entrance of the incoming object channel 102, the opening and closing fans 602 are opened to a position where they do not interfere with the swivel bucket 203 extending outside the incoming object channel 102, and before the opening and closing fans 602 close to cover the incoming object channel 102, the entrance of the swivel bucket 203 has rotated back into the incoming object channel 102. Thus, the sealing effect of the opening and closing fans 602 on the incoming object channel 102 as the swivel bucket 203 rotates can be utilized to achieve the purpose of closing the internal space of the outer housing 101 during the detection process, so that the heat inside the outer housing 101 will not leak out too much, thereby forming an energy-saving effect.
