TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle four-wheel alignment, in particular to a detection device for vehicle four-wheel alignment. BACKGROUND

[0002] Vehicle four-wheel alignment is a key link in automobile maintenance, and its accuracy is directly related to the vehicle's handling performance, tire service life and driving safety. With the continuous improvement of detection accuracy requirements in the automobile industry, traditional manual measurement methods have been gradually replaced by mechanical or semi-automatic devices. These devices not only improve measurement efficiency, but also provide more reliable technical support for modern automobile maintenance, and have a positive role in promoting the development of the industry. However, with the further improvement of market demand, the existing four-wheel alignment technology still faces many challenges. In actual operation, in order to realize the measurement of the spatial position and angle of the wheels, the following methods are usually used: first, using fixed supports to cooperate with manual measurement tools for calibration; second, setting support devices around the wheels and combining with auxiliary devices such as levels to ensure the stability of the measurement; third, using targets and optical instruments to complete the positioning detection. Although these methods show certain applicability in different scenarios, their core principles all depend on the design of the support structure and the cooperation of the measurement tools. However, the support structure in the existing technology generally has a problem, that is, it cannot guarantee the stability of the device and the accuracy of the measurement at the same time in complex environments. Especially in the case of multi-point support, how to ensure the coordination between the components and avoid measurement errors caused by improper installation or operation errors has become a technical problem to be solved. SUMMARY

[0003] In order to solve the above technical problems, the present application provides a detection device for vehicle four-wheel alignment.

[0004] The detection device for vehicle four-wheel alignment provided by the present application adopts the following technical solution:

[0005] A detection device for vehicle four-wheel alignment, comprising: a base, a longitudinal support rod and a transverse support rod cooperating with the base, a plurality of support sleeves arranged at the end of the longitudinal support rod and the transverse support rod away from the base and in contact with the side wall of the wheel, a level arranged on the base for visually checking whether the transverse support rod is placed horizontally, a hanging piece cooperating with the longitudinal support rod and hung on the top of the wheel, and a measurement target arranged on the side of the base away from the wheel.

[0006] By adopting the above technical scheme, the cooperation of the base with the longitudinal support rod and the transverse support rod can provide a stable support structure for the detection device, ensuring the stability of the device during the four-wheel alignment detection process; the multiple support sleeves arranged at the ends of the longitudinal support rod and the transverse support rod are in contact with the side wall of the wheel, which can not only accurately limit the position of the wheel, but also effectively avoid damaging the surface of the wheel; at the same time, the arrangement of the level meter enables the operator to intuitively judge whether the transverse support rod is in a horizontal state, thereby improving the accuracy of detection; the cooperation of the hanging piece with the longitudinal support rod can conveniently hang the detection device on the wheel, which is convenient, practical and easy to operate.

In addition, the level is arranged on the fixing seat, ensuring the stability thereof during use and improving the measurement accuracy and reliability of the detection device.

[0019] The supporting sleeve comprises an outer sleeve and an inner sleeve arranged integrally, one end of the outer sleeve is arranged in a tapered shape, and the inner sleeve and the outer sleeve are coaxially and penetratingly provided with a screw hole.

[0020] By adopting the above technical scheme, the contact stability with the side wall of the wheel can be effectively improved, and the wear of the side wall of the wheel is reduced. The inner sleeve and the outer sleeve are coaxially and penetratingly provided with the screw hole, so that the supporting sleeve can be firmly fixed on the longitudinal support rod or the transverse support rod, enhancing the reliability and adjustment accuracy of the overall structure, and thus ensuring a stable working state of the detection device during four-wheel positioning.

[0035] In combination with Figure 1 and Figure 2 As shown in the drawings, the embodiments of the present application disclose a detection device for vehicle four-wheel alignment, which comprises a longitudinal support rod 2 and a transverse support rod 3, a base 1, a plurality of support sleeves 4, a level 5, a hanging piece 6 and a measuring target 8; wherein the base 1 comprises a front cover 11, a rear cover 12 and a fixing seat 13, and the longitudinally arranged longitudinal support rod 2 and the transversely arranged transverse support rod 3 can be clamped and fixed through the front cover 11 and the rear cover 12 during installation, then the fixing seat 13 is installed on the front cover 11, and then the level 5 is installed on the fixing seat 13, so as to visually check whether the transverse support rod 3 is placed horizontally through the level 5.

[0036] In order to better enable the longitudinal support rod 2 and the transverse support rod 3 to better contact the plane where the side wall of the wheel is located, the support sleeve 4 is installed at the end of the longitudinal support rod 2 and the transverse support rod 3 away from the base 1.

[0037] Further, in order to facilitate positioning of the detection device to the side of the wheel, the hanging piece 6 is installed at the upper end of the longitudinal support rod 2, and during installation, the entire detection device can be hung to the wheel through the hanging piece 6, and then the transverse support rod 3 can be leveled through the level 5.

[0038] The detection device is provided with the base 1, the longitudinal support rod 2 and the transverse support rod 3, which can provide a stable support structure for the detection device, and ensure the stability of the device during the four-wheel positioning detection; the multiple support sleeves 4 arranged at the ends of the longitudinal support rod 2 and the transverse support rod 3 can contact the side wall of the wheel, which can accurately limit the position of the wheel and effectively avoid damaging the surface of the wheel; meanwhile, the arrangement of the level 5 can enable the operator to intuitively judge whether the transverse support rod 3 is in a horizontal state, thereby improving the accuracy of the detection; the cooperation of the hanging piece 6 and the longitudinal support rod 2 can conveniently hang the detection device on the wheel, which is convenient, practical and easy to operate.

[0039] Further, in order to enable the longitudinal support rod 2 and the transverse support rod 3 to provide a stable support structure for the detection device and to provide accurate positioning data for the measuring target 8, the longitudinal support rod 2 and the transverse support rod 3 are perpendicular to each other, so that the hanging claw 63 mounted on the longitudinal support rod 2 can conveniently and quickly hang the entire detection device on the top of the wheel, so that the transverse support rod 3 is basically in a horizontal state, and then the transverse support rod 3 can be finely adjusted by the level 5, so that it can meet the detection requirements.

[0040] In order to enable the detection device to be suitable for the detection of wheels of various specifications, the multiple support sleeves 4 and the corresponding longitudinal support rod 2 and transverse support rod 3 can be flexibly adjusted when connected, so that each support sleeve 4 can keep in contact with the side surface of the wheel of different specifications.

[0041] Specifically, as a preferred embodiment, the longitudinal support rod 2 and the transverse support rod 3 are circumferentially recessed with annular grooves 7 along the length direction, so that the support sleeve 4 sleeved on the longitudinal support rod 2 and the transverse support rod 3 can be fixed by the cooperation of the screw arranged on the support sleeve 4 and the annular groove 7 after being slid to the appropriate position, thereby avoiding loosening of the support sleeve 4 and providing better support for the installation and positioning of the entire detection device.

[0043] Since the outer diameter of the support sleeve 4 is much larger than the outer diameter of the longitudinal support rod 2 and the transverse support rod 3, and the outer diameter and structure of the plurality of support sleeves 4 arranged at the ends of the longitudinal support rod 2 and the transverse support rod 3 are the same, the plurality of support sleeves 4 can be arranged in the same plane, thereby better contacting the outer side wall of the wheel, so as to effectively improve the positioning detection accuracy of the entire detection device, and effectively avoid the measurement deviation caused by fixing the claw mechanism at the rim edge of the wheel and taking the wheel circumference as the positioning reference for data acquisition in the traditional detection device.

[0044] Further, the hanging piece 6 includes a hanging seat 61 adjustably arranged along the longitudinal support rod 2, a handle 62 arranged outside the hanging seat 61 to facilitate adjustment of the position of the hanging seat 61, and a hanging claw 63 for hanging the entire detection device on the wheel; the hanging claw 63 is arranged on both sides of the hanging seat 61, and the included angle is distributed in a range of 30 degrees to 75 degrees, preferably, the included angle between the two adjacent hanging claws 63 is 60 degrees and is symmetrically arranged along the longitudinal support rod 2; in addition, an anti-skid tooth 631 is arranged on the side wall of the wheel in contact with the two hanging claws 63, so as to effectively increase the friction between the hanging piece 6 and the wheel, prevent the hanging piece 6 from falling off due to slight vibration of the vehicle during detection, thereby improving the stability of detection, and also avoiding measurement errors caused by loosening of the hanging piece 6 during detection.

[0045] The above structure design not only ensures the stable support of the hanging claw 63 on the top of the wheel, but also avoids the inconvenience caused by too small or too large included angle for installation and disassembly of the hanging piece 6, thereby further improving the convenience and reliability of operation; in addition, since the hanging seat 61 is adjustably arranged along the longitudinal support rod 2, the adaptability of the hanging piece 6 can be effectively improved, thereby meeting the needs of different vehicle models.

[0046] In addition, in order to improve the strength of the adjacent hanging claws 63, prevent deformation or damage of the hanging claw 63 caused by external force, and at the same time provide effective avoiding space for the support sleeve 4, as a preferred embodiment, an arc-shaped reinforcing rib 64 is welded between the two hanging claws 63, so as to ensure that the support sleeve 4 arranged on the longitudinal support rod 2 does not interfere with the hanging claw 63 during adjustment, thereby improving the overall stability and operation convenience of the detection device.

[0047] The implementation principle of the present application is that, when the detection device is used, first, the positions of the support sleeve 4 and the hanging piece 6 are adjusted according to the wheel specifications, then the entire detection device is hung on the wheel through the two hanging claws 63 on the hanging piece 6, then the transverse support rod 3 is adjusted to a horizontal state through the level 5 arranged on the fixing seat 13, and the support sleeves 4 at the ends of the longitudinal support rod 2 and the transverse support rod 3 are brought into contact with the side wall of the wheel, at this time, the measurement target 8 fixed to the fixing seat 13 can be measured and collected by the external wheel positioning information collection system, and the wheel axial deflection and other positioning parameters can be calculated by the external wheel positioning information collection system.

[0048] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: all equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
