[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] See also Figure 1-3 , the present invention provides embodiment 1:

[0042] A vehicle B-pillar substrate structure includes a vehicle B-pillar substrate 1, an insert 2 and an anti-reflective layer 3. The vehicle B-pillar substrate 1 is provided with a groove 4 for the insert 2 to be embedded and fixed, wherein the insert 2 is adapted to the groove 4. The anti-reflective layer 3 can be a matte paint, leather texture or flocking layer.

[0043] See Figure 4-12 , the present invention provides embodiment 2:

[0044] A method for manufacturing a split-type vehicle B-pillar substrate structure comprises the following steps:

[0045] Step 1: Process the groove 4 on the B-pillar base plate 1 where the camera is to be installed;

[0046] Step 2: Using an injection molding process, an insert 2 is manufactured to be embedded in the tank body 4;

[0047] Step 3: Perform anti-reflective treatment on the surface of the insert 2;

[0048] Step 4: Fix the B-pillar base plate 1 to the fixture 5 and install the surface-treated insert 2 in the slot 4. The insert 2 can be fixed in the slot 4 by snap-fitting, ultrasonic welding (during ultrasonic fixing, a fuse is provided at the bottom of the insert 2 and fixed by locally welding the fuse at high temperature), gluing, or structural adhesive.

[0049] In order to enable the special-shaped B-pillar substrate 1 to be quickly positioned, the fixing tool 5 includes a base 51, a positioning mechanism 52 for positioning the B-pillar substrate 1, the positioning mechanism 52 includes a B-pillar position adjustment component 521 and multiple groups of B-pillar pre-tightening positioning components 522. Since all the snap grooves 6 of the special-shaped B-pillar substrate 1 are not on the same plane and have a certain curvature, the present application mainly arranges one group of B-pillar position adjustment components 521 and five groups of B-pillar pre-tightening positioning components 522 to position the six snap grooves 6 with relatively flat curvature on the B-pillar substrate 1. The positions of the B-pillar position adjustment component 521 and multiple groups of B-pillar pre-tightening positioning components 522 arranged in the middle of the base 51 can be set to a certain curvature adapted to the curved surface of the B-pillar substrate 1, and the specific structure will be adaptable and adjusted according to the curvature.

[0050] See Figure 6 、 7The B-pillar position adjustment component 521 is used to extend into a group of snap grooves 6 of the B-pillar base plate 1 and perform positioning (the snap groove 6 is an existing structure of the B-pillar base plate 1, and a snap plate 7 is provided on the top of the snap groove 6. The fixing tool 5 in this application is quickly positioned through the multiple groups of snap grooves 6 of the B-pillar base plate 1). The B-pillar position adjustment component 521 includes a first main rod 5211 and multiple groups of first side pressure rods 5212 (this application uses four groups of first side pressure rods 5212 to adapt to the four corners of the snap groove 6). The multiple groups of first side pressure rods 5212 are distributed around the periphery of the first main rod 5211 and slide The first connecting rod 5213 is connected between the first main rod 5211 and each group of first side pressure rods 5212. One end of the first connecting rod 5213 is hinged to the first side pressure rod 5212, and the other end is hinged to the first main rod 5211. The base 51 is provided with a first main rod groove 21 for the first main rod 5211 to slide up and down. In the initial state, the first main rod 5211 is at the highest position, and the end of the first connecting rod 5213 connected to the first main rod 5211 is higher than the end of the first connecting rod 5213 connected to the first side pressure rod 5212. When the main rod 5211 moves downward, the first connecting rod 5213 can drive the first side pressure rod 5212 to move toward the side away from the first main rod 5211. The first side pressure rod 5212 slides toward the side away from the first main rod 5211 and abuts against the inner wall of the buckle groove 6, driving the B-pillar base plate 1 to move until the four corners of the buckle groove 6 are pressed tightly. The first main rod 5211 moves downward in the following way: first, one end of the B-pillar base plate 1 is placed on the base 51, and then a group of buckle grooves 6 in the other end of the B-pillar base plate 1 are aligned with the first main rod 5211 and slowly lowered. Under the action of gravity of the B-pillar base plate 1, the first side pressure rod 5212 slides toward the side away from the first main rod 5211 and abuts against the inner wall of the buckle groove 6, driving the B-pillar base plate 1 to move until the four corners of the buckle groove 6 are pressed tightly. When the first side pressure rod 5212 moves outward, it will press the four corners of the snap groove 6 to complete the position adjustment of the B-pillar base plate 1.

[0051] See Figure 6 、 8, multiple groups of B-pillar pre-tightening positioning components 522 are used to extend into multiple groups of buckle grooves 6 of the B-pillar base plate 1 and perform positioning and pre-tightening. After the position of the B-pillar base plate 1 is adjusted by the B-pillar position adjustment component 521, the B-pillar base plate 1 can be positioned by the B-pillar pre-tightening positioning component 522, wherein the B-pillar pre-tightening positioning component 522 includes a second main rod 5221 and multiple groups of second side pressure rods 5222, and the multiple groups of second side pressure rods 5222 are distributed around the second main rod 5221 and are slidably arranged on the base 51. The second main rod 5221 and each group The second side pressure rods 5222 are connected to a second connecting rod 5223, one end of the second connecting rod 5223 is hinged to the second side pressure rod 5222, and the other end is hinged to the second main rod 5221. A second main rod groove 22 for the second main rod 5221 to slide up and down is provided on the base 51. In the initial state, the second main rod 5221 is at the lowest position, and the end of the second connecting rod 5223 connected to the second main rod 5221 is lower than the end of the second connecting rod 5223 connected to the second side pressure rod 5222. The second main rod 5221 can move up The second side pressure rod 5222 is driven by the second connecting rod 5223 to move toward the side away from the second main rod 5221, and the second side pressure rod 5222 slides toward the side away from the second main rod 5221 and abuts against the four corners of the buckle groove 6 to complete the positioning, wherein the second main rod 5221 moves downward in the following manner: a driving member that drives the second main rod 5221 to move upward is provided on the base 51, and after the B-pillar position adjustment assembly 521 adjusts the position of the B-pillar base plate 1, the driving member drives the second main rod 5221 to move upward until the B-pillar pre-tightening positioning assembly 522 is aligned with the B-pillar base plate 1 for positioning. It should be noted that: the fixing tool 5 is only provided with one set of first main rods 5211, which can ensure that the gravity of the B-pillar base plate 1 falls concentratedly on the first main rods 5211, so that the first main rods 5211 obtain sufficient downward driving force. After the B-pillar position adjustment component 521 adjusts the position of the B-pillar base plate 1, the multiple sets of B-pillar pre-tightening positioning components 522 correspond to the multiple sets of buckle grooves 6 one by one and are respectively located in the middle of the corresponding buckle grooves 6. After the second side pressure rods 5222 slide outward, they will just abut against the four corners of the buckle grooves 6 for positioning.

[0052] See Figure 9-11 , and also includes a locking assembly 8 for limiting the upward movement of the second main rod 5221. After the first main rod 5211 moves downward and the position of the B-pillar base plate 1 is adjusted by the first side pressure rod 5212, the locking assembly 8 releases the restriction on the upward movement of the second main rod 5221.

[0053] Specific reference Figure 9-11The locking assembly 8 includes a long rod 81 and multiple sets of locking rods 82, each set of locking rods 82 is located on one side of the long rod 81 and one end is hinged to the long rod 81, and a long rod slot 10 for the long rod 81 to slide is provided in the base 51, and the base 51 is located on one side of the long rod slot 10 and has multiple sets of side slots 11 corresponding to the multiple sets of locking rods 82. The side slots 11 are provided with a rotating hole 12 at one end away from the long rod slot 10, and the locking rod 82 is provided with a rotating rod 13 that is rotatably connected to the rotating hole 12 at one end away from the long rod slot 12. The outer wall of each set of second main rods 5221 is provided with a locking groove 14, and each set of locking rods 82 passes through the corresponding second main rod 5221 and is clamped in the locking groove 14. The long rod 81 is provided with a moving groove 15 below the first main rod 5211, and one end of the moving groove 15 is provided with a first inclined surface 16. The bottom end of the first main rod 5211 is provided with a rotating hole 12 that is connected to the second main rod 5221. The second inclined surface 17 abuts against the first inclined surface 16, and the first main rod 5211 abuts against the first inclined surface 16 to drive the long rod 81 to move so that the locking rod 82 disengages from the locking groove 14. One end of the long rod groove 10 is provided with a first spring 18 abutting against the long rod 81. After the first main rod 5211 disengages from the abutment with the first inclined surface 16, the first spring 18 can drive the long rod 81 to reset and drive the locking rod 82 to be re-engaged in the locking groove 14 through the long rod 81. It should be noted that: the locking rod 82 can be composed of a first locking rod 821 and a second locking rod 822. One end of the first locking rod 821 is fixed to the rotating rod 13 and the other end is provided with a sliding groove. One end of the second locking rod 822 is hinged to the long rod 81 and the other end is provided with a sliding rod 19 that forms a sliding connection with the sliding groove. In this way, the phenomenon of jamming during the rotation process driven by the sliding of the long rod 81 can be avoided.

[0054] See Figure 9 The driving member includes a second spring 20, which is fixed to the bottom end of the second main rod groove 22 and abuts against the bottom of the second main rod 5221.

[0055] See Figure 6 、 8When the second main rod 5221 is driven by the driving member to move up, a reset member 23 is rotated on the outer wall of the second main rod 5221. The reset member 23 includes a first hinge rod 231 and a second hinge rod 232. One end of the first hinge rod 231 is hinged on the second main rod 5221, and the other end is provided with a rod groove. One end of the second hinge rod 232 is hinged on the second side pressure rod 5222, and the other end is provided with a sliding rod 24 that is slidably connected to the rod groove. The end of the second hinge rod 232 away from the first hinge rod 231 is provided with a supporting rod 25, and the outer wall of the second side pressure rod 5222 is provided with a hidden groove 26 for hiding the supporting rod 25. In the initial state, the supporting rod 25 is located in the hidden groove 26 and does not affect the second side rod from entering the buckle groove 6. When the second main rod 5221 moves up and drives the second side pressure rod When the rod 5222 slides outward, the second main rod 5221 will drive the second hinge rod 232 to rotate through the first hinge rod 231, so that the push rod 25 is rotated to the outside of the hidden groove 26. After the second side pressure rod 5222 presses the corner of the buckle groove 6, the push rod 25 will be located above the B-pillar base plate 1. When the B-pillar base plate 1 completes the fixation of the insert 2 and is removed from the fixing tool 5, the top of the B-pillar base plate 1 will be against the push rod 25 and drive the second hinge rod 232 to rotate through the first hinge rod 231, so that the second hinge rod 232 is away from the end of the first hinge rod 231 and presses down the second main rod 5221. After the locking rod 82 groove of the second main rod 5221 is aligned with the locking rod 82, the locking rod 82 will automatically snap into the locking groove 14, realizing the reset of the second main rod 5221 and the second side pressure rod 5222.

[0056] See Figure 7 、 8 The sliding manner of the first side pressure rod 5212 and the second side pressure rod 5222 on the base 51 is as follows: a sliding groove 27 for the first side pressure rod 5212 and the second side pressure rod 5222 to slide is provided on the base 51, and a limit plate is provided at the bottom of the first side pressure rod 5212 and the second side pressure rod 5222. A limit groove 28 for the limit plate to slide is provided in the sliding groove 27, and a return spring 29 that resists the first side pressure rod 5212 is provided in the sliding groove 27 corresponding to the first side pressure rod 5212. The return spring 29 is arranged at one end of the sliding groove 27 away from the first main rod 5211. After the B-pillar base plate 1 is removed, the return spring 29 can make the first main rod 5211 move up to the highest position again to achieve reset.

[0057] See Figure 6 Since a certain displacement will occur when the B-pillar base plate 1 presses down the first main rod 5211, a sphere 30 is provided on the top of the first main rod 5211 for rotation. Most of the sphere 30 is located inside the first main rod 5211. The provision of the sphere 30 can reduce the friction generated when the first main rod 5211 and the B-pillar base plate 1 are displaced.

[0058] See Figure 5 、9 10. In order to reduce the difficulty of adjusting the position of the B-pillar base plate 1 by the B-pillar position adjustment assembly 521, a turntable 31 is rotatably provided on the base 51, a turntable groove 32 for the turntable 31 to rotate is provided on the base 51, a limit plate 33 is provided on the outer periphery of the turntable 31, a limit plate 33 groove is provided in the turntable groove 32 for the limit plate 33 to rotate, a locking block 34 is provided at the bottom end of the turntable 31, and an arc groove 35 is provided on the base 51 for the locking block 34 to slide along the circumferential side. The arc groove 35 is connected to the long rod groove 10, and the long rod 81 is provided with a V-shaped end 36 at one end close to the arc groove 35. The locking block 34 is provided with a card slot 37 for the V-shaped end 36 to be inserted into the position opposite to the long rod groove 10, wherein the card slot 37 has a straight groove at one end and a V-shaped groove at the inner end. The turntable 31 is also provided with a positioning card plate 38 for positioning one end of the B-pillar base plate 1. When the B-pillar base plate 1 is placed on the base 51 and is ready to be fixed, the B-pillar base plate 1 can be fixed to the base 51. When the second side pressure rod 5222 moves outward and contacts the inner wall of the snap groove 6, the B-pillar base plate 1 can be adjusted to a certain position by the turntable 31, thereby reducing the friction between the B-pillar base plate 1 and the base 51 during displacement.

[0059] See Figure 1-11 37 , the first end of the B-pillar base plate 1 is rotated to reduce the friction force when the position of the B-pillar base plate 1 changes.

[0060] After the first main rod 5211 slides to the lowest position, the long rod 81 slides to drive the locking rod 82 to rotate, and the locking rod 82 rotates to disengage the lock slot 14. Under the action of the second spring 20, the second main rod 5221 will move upward and drive the second side pressure rod 5222 to slide outward through the second connecting rod 5223 until it presses the four corners of the buckle slot 6 (the position of the B-pillar base plate 1 is adjusted by the B-pillar position adjustment component 521. After the second side pressure rod 5222 moves outward, it will directly press the four corners of the buckle slot 6. It should be noted that: after the first side pressure rod 5212 and the second side pressure rod 5222 are both pressed against the four corners of the buckle slot 6, the first connecting rod 5213 and the second connecting rod 5223 are both rotated. to a horizontal state, which can maintain a better positioning effect), and at the same time, by moving the second main rod 5221 upward, the first hinge rod 231 will drive the second hinge rod 232 to rotate and rotate the supporting rod 25 to the outside of the hidden groove 26, and then the insert 2 is placed in the groove body 4 of the B-pillar substrate 1, and the welding head of the ultrasonic welding equipment is moved down to a position that is against the upper surface of the insert 2. The high-frequency vibration of the welding head causes the insert 2 to locally generate high temperature, causing the fuse to melt, thereby fixing the insert 2 to the B-pillar substrate 1 (the ultrasonic welding equipment is connected to the driving equipment, which is a prior art technology. It is located above the base 51. When the B-pillar substrate 1 is positioned, both ends of the bottom are supported on the turntable 31).

[0061] After the insert 2 is fixed in the B-pillar base plate 1, the B-pillar base plate 1 is pulled up (a buffer rubber layer can be provided on the outer wall of the first side pressure rod 5212 and the second side pressure rod 5222 to prevent the special-shaped B-pillar base plate 1 from being stuck when being pulled up), the inner wall of the buckle groove 6 will abut against the push rod 25 and drive the push rod 25 to rotate into the hidden groove 26. The rotation of the push rod 25 will drive the first hinge rod 231 to rotate through the second hinge rod 232 and drive the second main rod 5221 to move downward. At the same time, the return spring 29 drives the first side pressure rod 5 212 moves toward one side of the first main rod 5211 and drives the first main rod 5211 to move upward. The first main rod 5211 moves upward and will disengage from the abutment with the first inclined surface 16. At this time, the long rod 81 will be reset under the action of the first spring 18 and drive the locking rod 82 to rotate. The rotation of the locking rod 82 will be stuck in the lock groove 14 to limit the second spring 20 from driving the second main rod 5221 to move upward. The movement of the long rod 81 also makes the V-shaped end 36 stuck in the locking groove 37 and limit the rotation of the turntable 31, which is convenient for the next positioning of the B-pillar base plate 1.
