DETAILED DESCRIPTION
[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0035] Figure 4 A structural schematic diagram of a fixing device provided in this application, such as Figure 4As shown, the fixing device includes a substrate 1, a positioning fixture 2, an angle adjustment component 3, a first limit component 4 and a second limit component 5, wherein the angle adjustment component 3, the first limit component 4 and the second limit component 5 are all fixed on the substrate 1, and the positioning fixture 2 is rotatably arranged on the substrate 1, that is, the positioning fixture 2 is connected to the substrate 1, and the positioning fixture 2 can rotate relative to the substrate 1 under the action of an external force. It should be understood that the angle adjustment component 3, the first limit component 4 and the second limit component 5 are all fixed on the substrate 1. In specific implementation, the three can be directly fixed on the substrate 1, or indirectly fixed on the substrate 1 through other components. Further, the positioning fixture 2 has a positioning groove 201 for accommodating the movement 100 of the movement assembly to be locked, so as to accommodate the movement 100 of the movement assembly to be locked through the positioning groove 201 and preliminarily position the movement assembly. When the angle adjustment component 3 is in the first state, the bottom of the positioning groove 201 forms a preset angle with the substrate 1, and the first limit component 4 and the angle adjustment component 3 work together to fix the relative position between the positioning fixture 2 and the substrate 1 to position the movement component. When the angle adjustment component 3 is in the second state, the bottom of the positioning groove 201 is parallel to the substrate 1, and the second limit component 5 and the angle adjustment component 3 work together to fix the relative position between the positioning fixture 2 and the substrate 1 to position the movement component.
[0036] In this scheme, the positioning fixture 2 can be fixed at two positions where a preset angle is formed between the bottom of the positioning groove 201 and the substrate 1 and the bottom of the positioning groove 201 is parallel to the substrate 1 through the cooperation of the angle adjustment component 3 with the first limit component 4 and the second limit component 5. When the positioning device provided by the present application is used to assemble the movement component, the mounting surface of the lens 300 can be made parallel to the mounting surface of the printed circuit board 200 through the design of the above-mentioned preset angle, thereby eliminating the need to manually adjust the angle of the fixture (that is, the positioning fixture 2), which is beneficial to improving the locking efficiency and can reduce the occurrence of crooked screw locking and inadequate locking.
[0037] Please combine Figure 4 and Figure 5When the above-mentioned angle adjustment component 3 is specifically set, in an optional technical solution, the angle adjustment component 3 includes a first linear drive structure 31 fixed to the substrate 1 and an adjustment member 32 fixed to the power output end of the first linear drive structure 31, and the positioning fixture 2 includes a first end D1 and a second end D2 relative to each other, the first end D1 is rotatably connected to the substrate 1, and is arranged in sequence with the adjustment member 32 along the first direction A, and the second end D2 is located between the first end D1 and the adjustment member 32. The adjustment member 32 includes a first part 321 and a second part 322 arranged along the first direction A and connected to each other, the distance between the surface of the first part 321 facing away from the substrate 1 and the substrate 1 is smaller than the distance between the surface of the second part 322 facing away from the substrate 1 and the substrate 1; the first part 321 and the second part 322 alternately support the second end D2 of the positioning fixture 2 under the action of the first linear drive structure 31. As Figure 6 As shown, when the angle adjustment component 3 is in the first state, the first portion 321 of the adjustment member 32 supports the second end of the positioning fixture 2, that is, the bottom of the positioning groove 201 forms a preset angle with the substrate 1, and the first limit component 4 and the angle adjustment component 3 work together to fix the relative position between the positioning fixture 2 and the substrate 1; Figure 7 As shown, when the angle adjustment component 3 is in the second state, the second part 322 of the adjustment member 32 supports the second end of the positioning fixture 2, that is, the bottom of the positioning groove 201 is parallel to the substrate 1, and the second limiting component 5 and the angle adjustment component 3 work together to fix the relative position between the positioning fixture 2 and the substrate 1.
[0038] It is worth noting that, for the convenience of observation, Figure 6 and Figure 7 Only part of the structure of the positioning fixture 2 is shown. For example, please combine Figure 4 and Figure 8 The positioning fixture 2 includes a supporting plate 23, a base 21 and a pressing plate 22, wherein the supporting plate 23 is rotatably connected to the substrate 1, the base 21 is fixed on the supporting plate 23 (that is, the base 21 is rotatably connected to the substrate 1 through the supporting plate 23), and the base 21 has the above-mentioned positioning groove 201; the pressing plate 22 can be opened and closed relative to the base 21. The upper surface of the supporting plate 23 is parallel to the bottom surface of the positioning groove 201, so the angle between the upper surface of the supporting plate 23 and the substrate 1 in the figure can reflect the angle between the bottom surface of the positioning groove 201 and the substrate 1.
[0039] Please continue to refer to Figure 8In a specific implementation, the pressing plate 22 has a first protrusion 221 for abutting against the printed circuit board 200 in the movement assembly to be locked and a second protrusion 222 for abutting against the housing of the lens 300 in the movement assembly to be locked. In this solution, on the basis of positioning the movement 100 by the positioning groove 201 on the base 21, the printed circuit board 200 and the housing of the lens 300 are fixed by the pressing plate 22, and the fixing of the movement assembly is more reliable.
[0040] In an optional implementation, the pressing plate 22 has a third end and a fourth end opposite to each other, the third end is rotatably connected to the base 21, and the fourth end is clamped to the base 21. In this solution, the fixing and opening between the pressing plate 22 and the base 21 are realized by the fourth end, so that the fixing between the pressing plate 22 and the base 21 is more reliable, and the opening of the pressing plate 22 is more convenient.
[0041] Exemplarily, the adjusting member 32 includes a connecting portion 323, which is located between the first portion 321 and the second portion 322 and is fixedly connected to both the first portion 321 and the second portion 322. Along the first direction A, the distance between the surface of the connecting portion 323 facing away from the substrate 1 and the substrate 1 gradually increases. That is, the first portion 321 and the second portion 322 are smoothly connected. In this way, the second end of the positioning fixture 2 can move more smoothly along the upper surface of the adjusting member 32, which is conducive to ensuring the smooth switching of the positioning fixture 2 between the two positions.
[0042] In an optional implementation, the surface of the second end D2 of the positioning fixture 2 away from the first end D1 of the positioning fixture 2 is an arc-shaped convex surface. This solution can also make the second end D2 of the positioning fixture 2 move more smoothly along the upper surface of the adjustment member 32, which is conducive to ensuring the smooth switching of the positioning fixture 2 between the two positions.
[0043] like Fig. 9 As shown, in a specific implementation, the angle adjustment assembly 3 may include two adjustment members 32, and the two adjustment members 32 are spaced apart in a direction parallel to the axis b of the positioning fixture 2. In this way, the support of the second end of the positioning fixture 2 is more reliable, and the load on the power output end of the first linear drive structure 31 can be reduced, which is conducive to extending the service life of the first linear drive structure 31.
[0044] Please combine Figure 4 , Fig.10 and Fig.11As shown, in a specific implementation, the first limit block 4 includes a first limit block 41, and the second limit block 5 includes a second limit block 51, and the first limit block 41 and the second limit block 51 are both located above the positioning fixture 2. When the angle adjustment component 3 is in the first state, the first limit block 41 can work together with the angle adjustment component 3 to fix the relative position between the positioning fixture 2 and the substrate 1; when the angle adjustment component 3 is in the second state, the second limit block 51 can work together with the angle adjustment component 3 to fix the relative position between the positioning fixture 2 and the substrate 1.
[0045] Taking the axial direction of the positioning jig 2 as the second direction, illustratively, the first limit block 41 and the second limit block 51 are respectively opposite to the two ends of the positioning jig 2 in the second direction, and the first limit block 41 and the second limit block 51 are both located above the second end of the positioning jig 2. In this way, when the first limit block 41 and the second limit block 51 act on the second end of the positioning jig 2, the second end of the positioning jig 2 can be more reliably limited.
[0046] In specific implementation, the first limiting assembly 4 includes a second linear drive structure 42, the first limiting block 41 is connected to the power output end of the second linear drive structure 42, and can be lifted and lowered under the action of the second linear drive structure 42. The second limiting assembly 5 includes a third linear drive structure 52, the second limiting block is connected to the power output end of the third linear drive structure 52, and can be lifted and lowered under the action of the third linear drive structure 52.
[0047] Exemplarily, the first linear drive structure 31, the second linear drive structure 42 and the third linear drive structure 52 can all be cylinders. Of course, the first linear drive structure 31, the second linear drive structure 42 and the third linear drive structure 52 can also be other structures, such as a screw structure or a gear rack structure.
[0048] In an optional implementation, Fig. 9 As shown, the base 21 is provided with an anti-fool structure 6, and the pressure plate 22 has a third protrusion 223. When the pressure plate 22 is buckled on the base 21, the third protrusion 223 acts on the anti-fool structure 6, thereby making the anti-fool structure 6 in a triggered state. After the pressure plate 22 is opened relative to the base 21, the third protrusion 223 is separated from the anti-fool structure 6, and the anti-fool structure 6 is switched to an untriggered state. Therefore, it is possible to judge whether the movement assembly is placed in place by the state of the anti-fool structure 6, which can reduce the possibility of misoperation. Exemplarily, the anti-fool structure 6 can be a small switch or other switch that can achieve this function.
[0049] The fixing device provided in this embodiment can cooperate with the automatic locking machine, and the automatic locking machine controls the angle adjustment component in the fixing device to switch between the first state and the second state, thereby completing the locking of the printed circuit board and the lens on the movement. During the locking operation, the locking surface is always in a flat state, the locking effect is consistent, and the problems of skewed locking and inadequate locking caused by the locking angle problem in manual locking can be improved.
[0050] For example, the positioning groove is designed according to the shape of the outer shell of the movement to play a role in positioning the movement. The PCB is fixed to the movement by 3 screws, and the lens is fixed to the movement by 4 screws. When the assembly of the movement components is assisted by the fixing device, the operation process can be as follows:
[0051] Step 1: Open the pressure plate of the positioning fixture and place the movement component (for example, the movement component of the vehicle-mounted smart driving instrument) into the positioning groove;
[0052] Step 2: Close the pressure plate of the positioning fixture to press the movement components and trigger the foolproof structure;
[0053] Step 3: Press the start switch, the second limit assembly presses the second end of the positioning fixture, and the automatic screw machine automatically locks the three screws of the PCB;
[0054] Step 4: After the locking is completed, the angle adjustment component switches to the first state, the first limit component presses the second end of the positioning fixture, and the automatic screw machine automatically locks the four screws of the lens;
[0055] Step 5: After the locking is completed, the positioning fixture is reset to the second state; the pressure plate of the positioning fixture is opened, and the locked movement assembly is taken out, and the operation is completed.
[0056] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
