In this embodiment, the four-wheel positioning measurement device 100 is installed on the lifting machine 200 carrying the vehicle for description. In this embodiment, the four-wheel positioning measurement device 100 obtains the positioning information of the tire by projecting the laser image on the surface of the tire, and then obtains the positioning information of the tire by acquiring and analyzing the laser image. The four-wheel positioning measurement device 100 of the embodiment is not prone to side turning when fixed, and has good protection performance. The specific embodiments will be described below:

[0046] Please refer to Figure 2The four-wheel alignment measurement device 100 of the embodiment comprises:

[0047] The support seat 1, the support rod 2 connected with the support seat 1, the camera 5 and the laser device 4 arranged on the support rod 2, the length direction of the support rod 2 is a first inclination angle with the length direction of the support seat 1; the laser device 4 is used for projecting a laser image towards the surface of the tire, and the camera 5 is used for acquiring the laser image and obtaining the alignment information of the tire from the laser image.

[0048] Here, it can be understood that the support seat 1 is used for supporting the laser device 4, and the support rod 2 is used for supporting the camera 5, so that when the four-wheel alignment measurement device 100 is fixed on the lifting machine 200 of the carrying vehicle, the laser device 4 and the camera 5 are in the correct measurement position; specifically, the laser device 4 is arranged on the support seat 1, and the laser device 4 is used for projecting laser light towards the tire, and the laser light forms a laser image on the surface of the tire; the camera 5 is arranged on the support rod 2, and the camera 5 is used for shooting the laser image on the surface of the tire, and analyzing the laser image, and finally obtaining the alignment information of the tire; the laser device 4 can be selected as a laser projection device, and the laser projection device projects a plurality of laser lights towards the surface of the tire to form a laser spot on the surface of the tire, that is, to form a laser image, and the camera 5 can be selected as a camera 5, and the camera 5 shoots a plurality of laser spots, and finally obtains the alignment information of the tire, such as the inclination angle of the tire, by analyzing the length, spacing, deformation and other data of the plurality of laser spots; it needs to be further explained that the length direction of the support rod 2 is a first inclination angle with the length direction of the support seat 1, and the support seat 1 is used for fixing the entire four-wheel alignment measurement device 100, and in the embodiment, one end of the support seat 1 is connected with the lifting machine 200 of the carrying vehicle, that is, the support seat 1 is arranged close to the tire, and the support rod 2 is arranged obliquely so that the camera 5 can be close to the tire, which facilitates the camera 5 to obtain a clear laser image, at the same time, such design can also make the center of gravity of the camera 5 close to the tire, avoiding that the entire four-wheel alignment measurement device 100 inclines due to the excessive weight of the camera 5; in addition, when the laser device 4 is arranged on the support seat 1, such design leaves a certain distance between the laser device 4 and the tire, which ensures the projection range of the laser device 4, avoids that the laser image projected on the surface of the tire is greatly distorted, improves the definition of the laser image, and improves the recognition accuracy of the camera 5; at the same time, such design takes into account that the center of gravity of the laser device 4 is as close to the tire as possible, which reduces the possibility of the four-wheel alignment measurement device 100 inclining; in addition, such design reduces the angle between the laser image projected by the laser device 4 and the camera 5, which reduces the recognition difficulty of the camera 5.

[0049] The working principle of the four-wheel alignment measurement device 100 provided in the embodiment is as follows:

[0050] The vehicle is stopped on the lifting machine 200 carrying the vehicle, the four-wheel alignment measuring device 100 is installed on the lifting machine 200 carrying the vehicle and is arranged close to the tire; specifically, the position of the fixing member 3 is adjusted so that the laser device 4 and the camera device 5 can be in the correct measuring position, the laser device 4 is started to form a laser image on the tire surface, and the laser image is photographed by the camera device 5, and the positioning information of the tire is obtained by analysis.

[0051] By adopting the technical scheme, the length direction of the support base 1 and the length direction of the support rod 2 form a first inclined angle, the design takes into account the projection range of the laser device 4, the gravity center of the laser device 4 close to the tire, the angle between the laser image projected by the laser device 4 and the camera device 5, improves the accuracy of the measurement result, reduces the possibility of the four-wheel alignment measuring device 100 overturning, and improves the protection performance.

[0052] In an embodiment, the laser device 4 is arranged on the support base 1 or the support rod 2; or the laser device 4 and the camera device 5 are integrated devices.

[0053] Here, it can be understood that when the laser device 4 is arranged on the support base 1, the laser device 4 can be arranged at any position in the length direction of the support base 1; when the laser device 4 is arranged on the support rod 2, the laser device 4 can be arranged at any position in the length direction of the support rod 1; or the laser device 4 and the camera device 5 can be integrated devices, that is, the integrated devices integrate the functions of projecting a laser image and taking a picture.

[0054] By adopting the technical scheme, the laser device 4 can be arranged at multiple positions, and the arrangement mode is high in flexibility.

[0055] In an embodiment, the first inclined angle ranges from 45° to 90°.

[0056] Optionally, the first inclined angle is 45°, 60°, 75° or 90°.

[0057] Preferably, the first inclined angle is 90°.

[0058] By adopting the technical scheme, when the first inclined angle is 90°, the support rod 2 is perpendicular to the support base 1, and the gravity center of the support rod 2 coincides with the center line of the support rod 2, which design leaves a certain distance between the camera device 5 and the tire, ensures that the camera device 5 has sufficient acquisition range, and also ensures that the gravity center of the camera device 5 is not too far from the tire to increase the risk of tilting.

[0059] In an embodiment, when the laser device 4 is arranged on the support base 1, the laser device 4 is located on the end of the support base 1 close to the support rod 2; and the camera device 5 is located on the end of the support rod 2 away from the support base 1.

[0060] Here, it can be understood that the laser device 4 is located on the end of the support base 1 close to the support rod 2, that is, the laser device 4 is arranged away from the fixing member 3, when the fixing member 3 is fixed on the lifting machine 200, the laser device 4 is away from the lifting machine 200, that is, the laser device 4 is arranged away from the tire, so as to ensure that the laser device 4 and the tire can be spaced apart by a sufficient distance and the laser image projected on the tire surface by the laser device 4 is clear; the camera device 5 is located on the end of the support rod 2 away from the support base 1, so that the camera device 5 is arranged away from the support base 1, and the camera device 5 is convenient to obtain the laser image of the tire surface.

[0061] By adopting the above technical scheme, the clarity of the laser image projected on the tire surface by the laser device 4 is improved, and the camera device 5 is convenient to obtain the laser image of the tire surface.

[0062] Please refer to Figure 3 and Figure 4 In an embodiment, the support base 1 comprises a support shell 11 and a power supply member 12 arranged in the support shell 11; wherein the support shell 11 is provided with a first connecting end 111 and a second connecting end 112 in the length direction of the support shell 11, the first connecting end 111 is used for fixing the four-wheel alignment measuring device 100, and the second connecting end 112 is used for connecting the camera device 5 and the laser device 4; the power supply member 12 is located in the shell at the first connecting end 111, and the power supply member 12 is used for electrically connecting the camera device 5 and the laser device 4.

[0063] Here, it can be understood that the support shell 11 is used for protecting the power supply member 12 in the support shell 11, so that the power supply member 12 can be protected from damage; the power supply member 12 is used for providing electric energy to the camera device 5;

[0064] Specifically, the support shell 11 is formed with the first connecting end 111 and the second connecting end 112, wherein the first connecting end 111 and the second connecting end 112 are oppositely arranged and located in the length direction of the support shell 11, the first connecting end 111 is used for connecting the lifting machine 200 of the bearing vehicle, and the second connecting end 112 is used for connecting the camera device 5; the power supply member 12 is used for electrically connecting the camera device 5, and the power supply member 12 has a large weight, so it is arranged at the first connecting end 111, so that the center of gravity of the entire support base 1 can be arranged close to the vehicle.

[0065] The working principle of the support base 1 provided in the embodiment is as follows:

[0066] The camera 5 is arranged on the second connecting end 112 of the support base 1, and the first connecting end 111 of the support base 1 is connected with the lifting machine 200 carrying the vehicle. Since the support base 1 has a certain length, the support base 1 can form a preset distance between the camera 5 and the tire of the vehicle.

[0067] By adopting the above technical scheme, since the power supply member 12 is heavy, arranging the power supply member 12 on the first connecting end 111 can make the gravity center of the entire support base 1 deviate to the vehicle. Since the power supply member 12 is located at the opposite ends of the support base 1 from the camera 5 and the laser device 4 respectively, the power supply member 12 balances the influence of the gravity of the camera 5 and the laser device 4 on the support base 1, reduces the possibility of the support base 1 tilting, and reduces the possibility of the camera 5 and the laser device 4 being damaged.

[0068] Please refer to Figure 5 In an embodiment, the power supply member 12 includes a power supply body 121 and two power supply body fixing sleeves 122 arranged at the two ends of the power supply body 121 respectively. The power supply body fixing sleeve 122 is sleeved on the end of the power supply body 121, and connects the power supply body 121 and the support shell 11, so that the power supply body 121 and the support shell 11 form a shock-absorbing gap.

[0069] Here, it can be understood that the power supply body 121 is used to provide electric energy, and the power supply body fixing sleeve 122 is used to fix the power supply body 121 and improve the protection performance of the power supply body 121.

[0070] Specifically, the power supply member 12 includes the power supply body 121 and the power supply body fixing sleeve 122. The power supply body 121 includes but is not limited to a rechargeable battery, which can be repeatedly charged and used. The power supply body fixing sleeve 122 includes but is not limited to a plastic fixing sleeve, and is sleeved on the end of the power supply body 121. Optionally, the two ends of the power supply body 121 can be sleeved with the power supply body fixing sleeve 122 respectively, so as to fix the two ends of the power supply body 121.

[0071] It needs to be further explained that the power supply body fixing sleeve 122 is arranged between the power supply body 121 and the support shell 11, that is, the power supply body fixing sleeve 122 abuts against the outer wall of the power supply body 121 and the inner wall of the support shell 11 respectively, so that a shock-absorbing gap is formed between the power supply body 121 and the support shell 11, and the protection performance of the power supply body 121 is improved.

[0072] By adopting the above technical scheme, the power supply body 121 is fixed in the support shell 11, and the protection performance of the power supply body 121 is improved, and the possibility of thermal runaway of the power supply body 121 is reduced.

[0073] In one embodiment, the power supply body fixing sleeve 122 extends to form a limiting plate 123 on the side facing the inside of the support shell 11, and the limiting plate 123 abuts against the power supply body 121.

[0074] Here, it can be understood that the limiting plate 123 is used to limit the power supply body 121.

[0075] Specifically, the limiting plate 123 is formed on the power supply body fixing sleeve 122, and the limiting plate 123 extends towards the opposite side of the power supply body fixing sleeve 122, that is, the limiting plate 123 extends along the length direction of the power supply body 121 towards the opposite side, so that the limiting plate 123 can abut against the part of the power supply body 121 in the length direction.

[0076] By adopting the above technical scheme, the limiting plate 123 abuts against the power supply body 121, thereby increasing the stability of the power supply body 121 fixed inside the support shell 11.

[0077] Please refer to Figure 4 In one embodiment, the support seat 1 further comprises a control member 13 electrically connected with the power supply member 12, and the control member 13 is located at the second connecting end 112.

[0079] Specifically, the control member 13 includes but is not limited to a chip or a circuit board having data collection, processing and transmission functions.

[0080] It needs to be further explained that the control member 13 is arranged at the second connecting end 112, and the control member 13 and the power supply member 12 are located at opposite ends of the support shell 11. Since the weight of the control member 13 is relatively light compared with the weight of the power supply member 12, the center of gravity of the support seat 1 is still close to the vehicle.

[0081] By adopting the above technical scheme, the operation of the power supply member 12 is controllable, and at the same time, the center of gravity of the support seat 1 is kept biased towards the vehicle.

[0082] In one embodiment, the control member 13 comprises a system mainboard and a charging control board stacked with the system mainboard, the system mainboard is electrically connected with the camera device 5, and the charging control board is electrically connected with the power supply member 12.

[0084] Specifically, the system mainboard is used to control the operation of the camera device 5, and the charging control board is used to control the charging and discharging operation of the power supply member 12.

[0085] By adopting the technical scheme, the system mainboard and the charging control board are stacked, which reduces the internal space of the support shell 11 occupied by the control member 13, and enables the support seat 1 to be miniaturized.

[0086] In one embodiment, the control member 13 further comprises a control member protection shell 131, the control member protection shell 131 being wrapped outside the system mainboard and the charging control board, and the control member protection shell 131 being connected with the support shell 11, so that the system mainboard and the charging control board form a shock-absorbing gap with the support shell 11.

[0087] Here, it can be understood that the control member protection shell 131 is used to protect the system mainboard and the charging control board.

[0088] Specifically, the control member protection shell 131 is formed with a receiving cavity, the shape and size of the receiving cavity matching the shape and size of the system mainboard and the charging control board, so that the system mainboard and the charging control board can be exactly accommodated in the receiving cavity, and the control member protection shell 131 is connected with the support shell 11, so that the system mainboard and the charging control board form a shock-absorbing gap with the inner wall of the support shell 11.

[0089] By adopting the technical scheme, the control member protection shell 131 can improve the protection performance of the system mainboard and the charging control board.

[0090] Please refer to Figure 6 In one embodiment, the support seat 1 further comprises a switch member 14 and a charging member 15, the switch member 14 and the charging member 15 being arranged on the support shell 11, the switch member 14 being electrically connected with the system mainboard, and the charging member 15 being electrically connected with the charging control board.

[0091] Here, it can be understood that the switch member 14 is used to control the camera 5, and the charging member 15 is used to control the power member 12.

[0092] Specifically, the switch member 14 includes but is not limited to a mechanical switch and a touch switch; and the charging member 15 includes but is not limited to a charging terminal.

[0093] By adopting the technical scheme, the intelligent degree of the control mode of the support seat 1 is improved.

[0094] In one embodiment, the support shell 11 comprises a support bottom shell 113 and a support top shell 114 which is in butt joint with the support bottom shell 113.

[0095] Here, it can be understood that the support bottom shell 113 and the support top shell 114 can be fixed in butt joint through fasteners.

[0096] By adopting the technical scheme, the support shell 11 has a simple structure and is easy to manufacture.

[0097] As Figure 7 andFigure 8 As shown, in one embodiment, the support rod 2 comprises a first support part 21 and a second support part 22 connected with the first support part 21; the first support part 21 is used for fixing the four-wheel alignment measuring device 100; the second support part 22 is used for connecting with the camera 5, and the second support part 22 extends from the first support part 21 in a direction away from the tire; the part of the second support part 22 away from the first support part 21 is used for supporting the camera 5.
