[0044] In order to illustrate the technical solution described in this application, the following is a detailed description with reference to specific drawings and embodiments.

[0045] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a magnetic four-wheel aligner 100, which is used to be installed at a fixed position outside the vehicle to be inspected, and is used to detect and locate the wheels of the vehicle to be inspected.

[0046] The magnetic four-wheel aligner 100 provided in the embodiment of the present application needs to be used in pairs. Taking the direction of the driving seat as a reference, one magnetic four-wheel aligner 100 is set on the right side of the vehicle to be inspected, for detecting the right front wheel and the right rear wheel, and the other magnetic four-wheel aligner 100 is set on the left side of the vehicle to be inspected, for detecting the left front wheel and the left rear wheel. The vehicle to be inspected is parked on a carrying device, and the magnetic four-wheel aligner 100 is fixed at a predetermined position on the carrying device. In addition, the two magnetic four-wheel aligners 100 need to be aligned and calibrated to ensure that the predetermined positional relationship is met between the two magnetic four-wheel aligners 100, thereby ensuring the consistency and accuracy of the detection of the wheels on both sides. The carrying device can be a lift, etc.

[0047] Specifically, if Figures 1 to 3 As shown, the magnetic four-wheel aligner 100 provided in the embodiment of the present application includes a magnetic base 3, a position detection module 5, an image acquisition module 6, and a control module (not shown). Among them, the magnetic base 3 is used to be adsorbed on the carrying equipment that carries the vehicle to be inspected, and is located on the same side as the wheel of the vehicle to be inspected; the position detection module 5 is provided on the magnetic base 3, and is used to obtain the first image information of the position detection module 5 of another magnetic four-wheel aligner 100 on the opposite side of the magnetic four-wheel aligner 100, that is, the position detection module 5 on the left and the position detection module 5 on the right are mutually calibrated; the image acquisition module 6 is provided on the magnetic base 3, and the image acquisition module 6 is used to obtain the second image information of the first calibration piece fixed on the wheel of the vehicle to be inspected; the control module is provided on the magnetic base 3, and the control module is electrically connected to the position detection module 5 and the image acquisition module 6 respectively, and is used to process the first image information and the second image information.

[0048] The magnetic four-wheel aligner 100 of the present application is adsorbed on the supporting equipment through the magnetic base 3. During the mutual calibration process of the two magnetic four-wheel aligners 100, the position and angle can be adjusted conveniently and quickly, which is beneficial to improving the installation efficiency of the magnetic four-wheel aligner 100 and reducing the adjustment workload.

[0049] In one embodiment, the position detection module 5 of the magnetic wheel aligner 100 includes an image detection component and a second calibration component. The image detection component is used to obtain first image information of the second calibration component of another magnetic wheel aligner 100 on the opposite side of the magnetic wheel aligner 100. The second calibration component is used to allow the image detection component of another magnetic wheel aligner 100 on the opposite side of the magnetic wheel aligner 100 to obtain first image information. Both first image information are transmitted to the control module.

[0050] The image acquisition module 6 includes two cameras, one for acquiring third image information of the front and rear wheels located on the same side of the vehicle to be inspected. More specifically, the magnetic wheel aligner 100 is positioned between the front and rear wheels on one side. One camera is tilted toward the front wheel to acquire third image information of the front wheel, and the other camera is tilted toward the rear wheel to acquire third image information of the rear wheel.

[0051] The control module is configured to be communicatively connected to the control module of another magnetic four-wheel aligner 100 on the opposite side of the magnetic four-wheel aligner 100 ; or, the control module is configured to be communicatively connected to the control terminal.

[0052] More specifically, there is a communication connection between the control module on the left and the control module on the right. The control module on the right is used to transmit the first image information, second image information and third image information it obtains to the control module on the left. The control module on the left processes the two first image information, two second image information and two third image information. Of course, all data can also be sent to the control module on the right for processing, which is not limited here.

[0053] Alternatively, the control module on the left and the control module on the right are respectively connected to the external control terminal for communication, and send the first image information, second image information and third image information respectively acquired to the external control terminal, which processes the two first image information, two second image information and two third image information.

[0054] Alternatively, the control module on the left and the control module on the right are respectively connected to the external control terminal for communication, and the external control terminal forwards the first image information, second image information and third image information corresponding to the control module on one side to the control module on the other side, and the control module on the other side processes the two first image information, two second image information and two third image information, and sends the processing results to the external control terminal for display.

[0055] like Figure 3 and Figure 4 As shown, the magnetic wheel aligner 100 further includes a housing 4 having a cavity (not shown) within which the position detection module 5, image acquisition module 6, and control module are disposed. The specific shape of the housing 4 is designed based on the relative positions of the position detection module 5, image acquisition module 6, and control module, while also taking into account ease of handholding.

[0056] The housing 4 can be made of plastic and manufactured by integral injection molding to obtain the required external shape and cavity shape.

[0057] In an embodiment of the present application, the magnetic base 3 is connected to the shell 4, and the magnetic base 3 is fixedly adsorbed on the carrying device, so that the shell 4 and the position detection module 5, image acquisition module 6 and control module inside it can be fixedly set relative to the vehicle to be inspected and the carrying device.

[0058] Next, see Figure 4 、 Figure 5 and Figure 6 As shown, in one embodiment, the magnetic base 3 includes a permanent magnet 321 .

[0059] Specifically, see Figure 4 、 Figure 5 and Figure 6 As shown, the magnetic base 3 includes a base 31 and a magnetic assembly 32 mounted on the base 31. The magnetic assembly 32 includes one or more permanent magnets 321. The base 31 is fixedly connected to the housing 4.

[0060] Optionally, the base 31 and housing 4 are detachably connected. This arrangement allows the magnetic base 31 to be manufactured and installed as a standalone module, as the magnetic assembly 32 includes a permanent magnet 321 and does not require a separate power supply structure to generate magnetic attraction. In particular, the detachable connection between the base 31 and housing 4, allowing for independent manufacturing and installation, helps reduce the manufacturing costs of the housing 4.

[0061] In an alternative embodiment, see Figure 4 As shown, one end of the housing 4 is provided with a mounting port 40, which can be connected to the cavity or not. Figures 4 to 6 As shown, the base 31 includes a connecting portion 312 and a fixing portion 311. The magnetic assembly 32 is fixedly mounted on the fixing portion 311. The connecting portion 312 is located at the end of the fixing portion 311 facing away from the magnetic assembly 32. The connecting portion 312 is located within the mounting opening 40 of the housing 4. In other words, the connecting portion 312 of the base 31 is inserted into the housing 4. Furthermore, the connecting portion 312 and the housing 4 can be fixedly connected by fasteners (such as bolts).

[0062] On this basis, a recessed portion 3120 may be formed on the connecting portion 312. Figure 6 The arrangement of the recessed portion 3120 makes the connecting portion 312 hollow, which is beneficial for reducing the weight and material cost of the connecting portion 312 and the base 31 .

[0063] Alternatively, the reverse is also possible: a mounting opening 40 is formed on the connection portion 312 of the base 31 and is sleeved onto one end of the housing 4. The connection portion 312 of the base 31 and the one end of the housing 4 can be fixedly connected by fasteners (such as bolts). Similarly, a recessed portion 3120 is formed at one end of the housing 4. The recessed portion 3120 can be connected to the cavity or not, which also helps reduce the weight and material cost of the housing 4.

[0064] See also Figure 4 、 Figure 5 and Figure 6 As shown, the magnetic attraction component 32 includes one or more permanent magnets 321. In order to ensure that the magnetic attraction component 32 can provide a suitable magnetic attraction force, the number of the permanent magnets 321 can be multiple. Figures 4 to 6 Three are shown.

[0065] See also Figure 5 As shown, the fixing portion 311 of the base 31 is provided with a corresponding number of mounting grooves 3110, and a portion of the permanent magnet 321 is located within the mounting grooves 3110. The mounting grooves 3110 are used to roughly define the position of the permanent magnet 321. The shape of the mounting grooves 3110 is adapted to the shape of the permanent magnet 321, for example, both are circular.

[0066] In one embodiment, the permanent magnet 321 is bonded to the fixing portion 311 . The adhesive may be provided on the inner bottom wall and / or inner peripheral wall of the mounting groove 3110 .

[0067] In another embodiment, the magnetic attraction assembly 32 further includes a corresponding number of first connecting members 33, and the first connecting members 33 connect the fixing portion 311 and the permanent magnet 321. Figure 5 and Figure 6 Specifically, the permanent magnet 321 includes a permanent magnet body 3211 and a base 3212 fixedly connected to the permanent magnet body 3211. The first connecting member 33 includes a threaded rod 331 disposed on the side of the base 3212 facing the mounting slot 3110, and a nut 332. The fixing portion 311 is provided with a corresponding mounting hole 3111. The threaded rod 331 passes through the mounting slot 3110 through the mounting hole 3111. The nut 332 engages with the threaded rod 331 from the side of the fixing portion 311 facing away from the mounting slot 3110, thereby fixing each permanent magnet 321 in the mounting slot 3110.

[0068] The permanent magnet body 3211 can be made of ferrite permanent magnet material, neodymium iron boron permanent magnet material, etc.

[0069] Of course, in some embodiments, the permanent magnet 321 can be fixedly connected to the base 31 in a variety of ways, for example, fixedly connected to the base 31 by bonding and the first connecting member 33 described above.

[0070] See also Figure 6 As shown, the connecting portion 312 is smaller than the fixing portion 311 and is provided with a recessed portion 3120. This allows the nut 332 to be positioned both inside and outside the recessed portion 3120 on the side of the fixing portion 311 facing away from the mounting slot 3110. More specifically, for three permanent magnets 321, one nut 332 can be positioned inside the recessed portion 3120, while the other two nuts 332 can be positioned on opposite sides of the recessed portion 3120.

[0071] like Figure 5 and Figure 6 As shown, the first connecting member 33 may further include a washer 333, which is arranged between the nut 332 and a side surface of the fixing portion 311 facing away from the installation groove 3110 to buffer the force between the nut 332 and the fixing portion 311 to avoid damage to the fixing portion 311.

[0072] Also, please continue reading Figure 5 and Figure 6 As shown, in one embodiment, the magnetic base 3 further includes a baffle 35, which is provided on a surface of the fixing portion 311 facing away from the mounting groove 3110 and is fixedly connected to the fixing portion 311, and is used to shield the first connecting member 33 located on the back of the fixing portion 311. The baffle 35 is provided on the outside of the connecting portion 312, such as on opposite sides, to facilitate installation.

[0073] like Figure 5 and Figure 6 As shown, the baffle 35 is connected to the fixing portion 311 via a second connecting member 34. Specifically, the second connecting member 34 passes through the baffle 35 and is fixed to the fixing portion 311, thereby fixing the baffle 35 to the fixing portion 311. The second connecting member 34 can be a screw or a bolt.

[0074] See also Figure 4 、 Figure 5 and Figure 6 As shown, in one embodiment, the magnetic assembly 32 further includes a plurality of first sheaths 36, which are mounted on the end of each permanent magnet 321 facing away from the base 31. The surface of the permanent magnet 321 facing away from the base 31 serves as a magnetic surface for attracting the surface of a supporting device. Because both the magnetic surface and the surface of the supporting device are hard surfaces, the first sheaths 36 prevent the magnetic surface from scratching the surface of the supporting device.

[0075] The material of the first sheath 36 can be selected to have a hardness less than that of the material of the permanent magnet 321 and less than that of the surface of the material of the supporting device. For example, the first sheath 36 can be made of a plastic material, either hard plastic or soft plastic. More specifically, the first sheath 36 can be made of polyoxymethylene, polyamide, polycarbonate, polyphenylene sulfide, silicone, or the like.

[0076] Please continue reading Figure 4 、 Figure 5 and Figure 6 As shown, a magnetic base 3 further includes a second sheath 37 disposed on the end of the magnetic assembly 32 facing away from the base 31. The second sheath 37 is mounted over the magnetic assembly 32 and the base 31, and is provided with through-holes 370 through which the first sheaths 36 are exposed. Because the shape of the first sheath 36 corresponds to the shape of the permanent magnet 321, the second sheath 37 is entirely mounted outside the magnetic assembly 32, providing a smooth surface for the entire magnetic base 3, ensuring that the entire magnetic base 3 maintains planar contact with the supporting device.

[0077] Optionally, the surface of the first sheath 36 is flush with the surface of the second sheath 37 .

[0078] The material of the second sheath 37 can be selected to have a hardness less than that of the material of the permanent magnet 321 and less than that of the surface of the material of the supporting device. For example, the second sheath 37 can be made of a plastic material, either hard or soft. More specifically, the second sheath 37 can be made of polyoxymethylene, polyamide, polycarbonate, polyphenylene sulfide, silicone, or the like.

[0079] In one embodiment, the magnetic base 3 may include an electromagnet (not shown).

[0080] like Figure 3 As shown, the magnetic wheel aligner 100 also includes a secondary battery 7 disposed in the cavity and a charging circuit board (not shown) disposed on the housing. The charging circuit board is connected to the secondary battery 7 and to the coil. The secondary battery 7 can provide the power required for the position detection module 5, the image acquisition module 6, and the control module. Alternatively, the secondary battery 7 can be omitted, and the charging circuit board can be directly connected to the external power supply through the interface.

[0081] The electromagnet consists of an iron core and a coil wound around it. In this embodiment, one end of the housing 4 is provided with an opening communicating with its inner cavity; one end of the iron core is located at the opening and has a magnetic surface for adsorption to a supporting device. In an alternative embodiment, the electromagnet can also be mounted on a base 31 and connected to the housing 4 via the base 31, and connected to the internal charging circuit board via a wire running through the base 31.

[0082] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
