It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the utility model can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0041] It should be understood that the reference to "some embodiments" throughout the specification means that specific features, structures or characteristics related to the embodiments are included in at least one embodiment of the utility model. Therefore, the "in some embodiments" appearing in various places throughout the specification does not necessarily refer to the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.

[0042] The following describes in detail a vehicle body bracket provided by the utility model by listing specific embodiments.

[0043] Reference Figures 1 to 4 The utility model provides a vehicle body bracket, including a base plate 10 and at least one support assembly 2; the base plate 10 is provided with a plurality of mounting positions, and the plurality of mounting positions are arranged in an array; the support assembly 2 is detachably connected to the base plate 10 through the mounting positions.

[0044] Specifically, the substrate 10 can be a measuring plate commonly available on measuring equipment such as a three-dimensional measuring machine or a blue light scanning device, which has high-precision dimensional requirements, and the approximate size can be read from the substrate 10 during measurement. The substrate 10 of the embodiment of the utility model is provided with multiple mounting positions, and the multiple mounting positions are arranged in an array. Preferably, the spacing between two adjacent mounting positions can be set to be the same. For example, the multiple mounting positions are distributed in a rectangular shape on the substrate 10. If the spacing between two adjacent mounting positions is 50mm, 50mm, 100mm and other dimensions with a value of an integer multiple of 50mm can be directly read from the substrate 10; if the spacing between two adjacent mounting positions is 100mm, 200mm, 300mm and other dimensions with a value of an integer multiple of 100mm can be directly read from the substrate 10. The support assembly 2 is detachably connected to the substrate 10 through the mounting position, and the support assembly 2 is used to support the components to be measured, and the components to be measured include but are not limited to fenders, side panels, decorative panels, transverse and longitudinal beams and other vehicle parts.

[0045] like Figure 1 and Figure 2As shown, in actual application, the vehicle body bracket needs to be placed in a measuring device such as a three-dimensional measuring machine or a blue light scanning device for use. The three-dimensional measuring machine and the blue light scanning device are one of the most effective methods to obtain dimensional data. When measuring the part to be measured, the vehicle body bracket is first placed in the above-mentioned measuring device, and then the part to be measured is placed on the support component 2 of the vehicle body bracket. The support component 2 is used to realize the support positioning of the part to be measured. After the positioning of the part to be measured is completed, the measuring device can be turned on to measure it. It should be noted that the use of the vehicle body bracket needs to be controlled by a control system. The control system can be composed of a touch screen and a PLC (Programmable Logic Controller), or an industrial computer plus a motion control card. It can realize the control of the vehicle body bracket. The specific form is not limited in this embodiment. The control system can control the support component 2 of the vehicle body bracket to move to any position of the part to be measured, so as to realize the effective support of the support component 2 to the part to be measured.

[0046] The vehicle body bracket of the utility model includes a base plate 10 and at least one support assembly 2. When there is one support assembly 2, an additional support column can be installed on the base plate 10, and the support column cooperates with the support assembly 2 to support the component to be tested; when there are two support assemblies 2, the two support assemblies 2 cooperate to support smaller components such as strips; when there are three or more support assemblies 2, multiple support assemblies 2 cooperate to support larger components such as plates; the number of support assemblies 2 can be set according to the shape and size of the component to be tested, and this embodiment does not limit this.

[0047] In the vehicle body bracket of the present invention, the support assembly 2 is detachably connected to the substrate 10 through the mounting position on the substrate 10. If a larger-sized component to be measured needs to be measured, the support assembly 2 can be connected to a position close to the edge of the substrate 10, and the spacing between two adjacent support assemblies 2 is set to be larger, so that the overall size of the vehicle body bracket is larger, thereby achieving support positioning for the larger-sized component to be measured; Figure 3 The schematic diagram shows that the vehicle body bracket includes four support components 2, which are connected to the edge of the substrate 10 and are spaced apart from each other. In this case, the vehicle body bracket is suitable for supporting and positioning a larger part to be measured. If a smaller part to be measured needs to be measured, the support component 2 can be connected to a position close to the center of the substrate 10, and the spacing between two adjacent support components 2 is set to be smaller, so that the overall size of the vehicle body bracket is smaller, thereby achieving support and positioning for a smaller part to be measured; Figure 4The schematic diagram shows that the vehicle body bracket includes four support components 2, and the four support components 2 are connected to the center of the substrate 10 and two adjacent support components 2 are arranged closely. In this case, the vehicle body bracket is suitable for supporting and positioning the components to be tested with smaller sizes. Therefore, by adjusting the connection position of the support component 2 on the substrate 10, the support and positioning of the components to be tested with different sizes can be achieved, which effectively improves the versatility of the vehicle body bracket and broadens the scope of application of the vehicle body bracket.

[0048] Optionally, refer to Figure 1 Each of the support components 2 includes a support member 3 and a base 4; the support member 3 is movably connected to the base 4, the support member 3 is used to support the component to be tested, and the base 4 is detachably connected to the substrate 10 through the mounting position.

[0049] Specifically, each support component 2 includes a support member 3 and a base 4. The support member 3 is used to support the component to be measured. In order to ensure that the support member 3 can fully abut against the component to be measured and provide stable support for the component to be measured, the support member 3 needs to have the ability to move. Therefore, the support component 2 is provided to include a base 4. The support member 3 is movably connected to the base 4. The base 4 is used to support the support member 3. The side of the base 4 facing away from the support member 3 is detachably connected to the substrate 10 through the mounting position on the substrate 10, thereby realizing the detachable connection between the support component 2 and the substrate 10.

[0050] Optionally, refer to Figure 2 and Figure 3 The installation position is a connecting hole 11, and the base 4 is provided with a connecting piece 41; the connecting piece 41 is passed through the connecting hole 11 to detachably connect the base 4 to the substrate 10.

[0051] Specifically, in some embodiments, the mounting position on the substrate 10 is in the form of a connection hole 11, and the base 4 is provided with a connection member 41, which is inserted into the connection hole 11 to detachably connect the base 4 to the substrate 10. Accordingly, the connection member 41 can be a pin, a screw, a rivet or the like, and the connection hole 11 on the substrate 10 can also be a threaded hole. Figure 3 As shown, in some embodiments, the base 4 can be configured as a frame structure formed by a plurality of side beams fixedly connected to facilitate the operator to locate the position of the connecting member 41 and smoothly connect it with the connecting hole 11, while helping to reduce the overall weight of the support assembly 2 and realize a lightweight design of the vehicle body bracket.

[0052] Optionally, refer to Figure 3 There are at least two connecting members 41 , and at least two connecting members 41 are arranged at intervals, and the interval between two adjacent connecting members 41 is an integer multiple of the interval between two adjacent connecting holes 11 .

[0053] Specifically, there are at least two connectors 41 on the base 4, and at least two connectors 41 are arranged at intervals, and the spacing between two adjacent connectors 41 is an integer multiple of the spacing between two adjacent connection holes 11 on the substrate 10, so as to ensure that the connector 41 can be smoothly inserted into the connection hole 11, so as to realize the detachable connection between the base 4 and the substrate 10. For example, if the spacing between two adjacent connection holes 11 is 50mm, the spacing between two adjacent connectors 41 can be 50mm, 100mm, 150mm, etc., and if the spacing between two adjacent connection holes 11 is 100mm, the spacing between two adjacent connectors 41 can be 100mm, 200mm, 300mm, etc., which can be determined according to the size of the base 4 and the substrate 10, and this embodiment does not limit this. Further, the base 4 is set to a rectangular structure, and at least two connectors 41 are distributed along the diagonal of the base 4 to enhance the reliability of the connection between the base 4 and the substrate 10. Exemplarily, if there are two connectors 41, the two connectors 41 are distributed along a diagonal line of the base 4; if there are four connectors 41, two of the connectors 41 are distributed along a diagonal line of the base 4, and the other two connectors 41 are distributed along another diagonal line of the base 4, so as to enhance the reliability of the connection between the base 4 and the substrate 10.

[0054] Optionally, refer to Figure 1 Each of the support assemblies 2 further includes a control cabinet 5 and at least one driving mechanism; the driving mechanism is connected to the support member 3 and is used to drive the support member 3 to move relative to the base 4; the control cabinet 5 is arranged on the base 4, and a control panel is arranged in the control cabinet 5, and the control panel is electrically connected to at least one of the driving mechanisms and is used to control the driving mechanism to move.

[0055] Specifically, each support assembly 2 further includes a control cabinet 5 and at least one driving mechanism, the driving mechanism is used to drive the support member 3 to move relative to the base 4, the number of driving mechanisms is not less than the number of support members 3, that is, each support member 3 is at least connected to one or more driving mechanisms, and different driving mechanisms can drive the support member 3 to move relative to the base 4 in different directions. In this embodiment, the driving mechanism can be selected from servo motors, stepper motors, etc. The servo motor has high precision, fast response, and high stability, and the stepper motor has a simple structure, high reliability and low cost. In practical applications, the form of the driving mechanism can be reasonably selected according to the measurement needs of the component to be measured, and this embodiment is not limited to this. The control cabinet 5 is arranged on the base 4, and the control cabinet 5 and the base 4 can be assembled and connected together by fasteners. A control board is arranged in the control cabinet 5, and the control board is essentially one or more PCB (printed circuit board) boards. The control board is provided with an integrated circuit, which can realize functions such as signal transmission, processing, and conversion. The control board is electrically connected to the driving mechanism and can control the driving mechanism to move. The action of the driving mechanism determines the amount of movement of the driving mechanism driving the support member 3 to move relative to the base 4. Among them, each driving mechanism can be connected to a control board separately to realize independent control of each driving mechanism, and this method has low design requirements for the control board; multiple driving mechanisms can also be connected to a control board at the same time to realize the integrated design of the control board, and this method has high design requirements for the control board. The control board of one or more driving mechanisms is arranged in the control cabinet 5, and correspondingly, part of the wiring harness connecting the driving mechanism and the control board can be correspondingly hidden in the control cabinet 5, thereby helping to improve the neatness and aesthetics of the vehicle body bracket.

[0056] Further, the control panel in the control cabinet 5 can be one or more, and no matter it is to be a control panel or multiple control panels, the wiring terminals of the control panel extend from the control cabinet 5 through a wiring harness. It can be understood that the control panel needs to be electrically connected to the external control system. The control system can be composed of a touch screen and a PLC, or it can be composed of an industrial computer plus a motion control card. The control system is used to input instructions to the control panel so that the control panel controls the driving mechanism to act. It can be understood that the electrical connection between the control panel and the control system needs to be realized through a wiring harness. Usually, multiple wiring harnesses need to be used, which leads to a complex wiring harness structure of the vehicle body bracket, which is easy to affect the appearance and easy to cause wiring harness entanglement, wiring errors, etc. Therefore, in this embodiment, the wiring terminal of the control panel extends from the control cabinet 5 through a wiring harness, and is electrically connected to the control system through the wiring harness. The wiring harness is a thick wiring harness with a relatively thick diameter, and the thick wiring harness is coated with multiple thin wiring harnesses with relatively thin diameters, thereby realizing the storage and fixation of multiple wiring harnesses, improving the aesthetics of the wiring harness structure in the vehicle body bracket, and reducing the probability of wiring harness entanglement, wiring errors, etc.

[0058] Specifically, the support member 3 includes a mounting seat 31, a quick-change mechanism 32 and a support head 33. The mounting seat 31 is movably connected to the base 4. The quick-change mechanism 32 is fixed on the mounting seat 31. The quick-change mechanism 32 can be a quick-change fixture commonly used in the market. The support head 33 is fixed on the quick-change mechanism 32. Since the support assembly 2 supports and positions different types of components to be tested, the support head 33 required to be used may be different, and the support head 33 can be quickly fixed or loosened by adjusting the quick-change mechanism 32. When the support head 33 is loose, the support head 33 can be taken out of the quick-change mechanism 32 and replaced. At the same time, when the support head 33 is used for a long time, the support head 33 may wear out with the component to be tested, resulting in a decrease in its support positioning accuracy, and the use of the quick-change mechanism 32 also facilitates the disassembly and maintenance of the support head 33.

[0059] Optionally, refer to Figure 5 and Figure 6 The support head 33 is a magnetic member or a vacuum suction cup, or the support head 33 is a pin or a pin hole.

[0060] Specifically, if Figure 5 As shown, in some embodiments, the support head 33 is a magnetic member or a vacuum suction cup, so that the component to be tested is fixed by adsorption through the adsorption effect of the magnetic member or the vacuum suction cup. This fixing form is suitable for components to be tested with high surface flatness such as plates. Figure 6 As shown, in other embodiments, the support head 33 is a pin or a pin hole, and the component to be measured is connected and fixed by connection with the pin or the pin hole. This fixing form is suitable for the component to be measured with a hole structure or an axis structure on the surface.
