Technical Field

[0001] This utility model relates to the field of automotive hinges, and in particular to an automotive hinge opening and closing degree adjustment device. Background Technology

[0002] In the current automotive manufacturing industry, the car hinge assembly is a safety feature that must be installed in mid-range and high-end sedans. It is installed at the connection between the front and rear hoods and doors and the car body, and has two basic functions: first, to connect the car body to the hood (door) and ensure and maintain the position of the hood (door) relative to the car body; second, to ensure and facilitate the opening and closing of the hood (door). When measuring the contour of the car hinge assembly surface and the position of the mounting holes using a coordinate measuring machine (CMM), the opening and closing angle of the car hinge needs to be adjusted to the theoretical closing angle. During measurement, the opening and closing angle of the car hinge is generally adjusted manually. The operator needs to fix the car hinge body panel, manually adjust the angle between the hinge's moving panel (hood panel or door panel) and the body panel, and after adjusting it to the approximate position, use a CMM to measure the angle until the error between the hinge opening and closing angle measured by the CMM and the theoretical closing angle marked on the customer's drawing is less than 0.1 degrees. This operation is cumbersome, time-consuming, and has a large angle error, resulting in a significant error in the final CMM measurement result. Utility Model Content

The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0035] The following is combined Figures 1-6 This invention describes an automotive hinge opening and closing degree adjustment device.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in one embodiment, an automotive hinge opening and closing degree adjustment device includes a base 110, a track 120, a slider 130, a top block 140, and a locking member 150.

[0037] The track 120 is mounted on the base 110 and extends away from the base 110. Specifically, the track 120 is vertically fixed to the base 110 by fasteners. To facilitate height adjustment, a plurality of height-adjusting blocks 160 are also provided. The height-adjusting blocks 160 and the base 110 have pin holes. The height-adjusting blocks 160 are used to support the bottom of the base 110 and are restricted from lateral movement relative to the base 110 by pins.

[0038] The slider 130 is slidably mounted on the track 120. The top block 140, with a conical top, is mounted on the slider 130 and rests against the bottom side of the movable page 52 of the hinge 50, pushing the movable page 52 of the hinge 50 to rotate relative to the body page 54. During measurement, the slider 130 is slid along the track 120 until the opening degree between the movable page 52 and the body page 54 reaches the desired value, and then fixed. Specifically, the opening degree needs to be adjusted multiple times. After the initial adjustment to the approximate position, multiple adjustments are made until it reaches the allowable error range.

[0039] Locking element 150 is used to limit the relative movement of slider 130 and track 120. Adjust the opening degree of hinge 50, loosen locking element 150, and then tighten locking element 150.

[0040] When measuring the opening degree of hinge 50, the body panel 54 of hinge 50 is fixed, and the position of slider 130 relative to track 120 is adjusted with fastener 150 in a loose state until the angle between movable panel 52 of hinge 50 and body panel 54 reaches the desired value, and then locking member 150 is locked.

[0041] In this embodiment, the car hinge engagement adjustment device measures the opening degree of the hinge 50 by fixing the body panel 54 of the car hinge, with the top block 140 resting against the bottom side of the free end of the movable panel 52. The slider 130 is adjusted along the track 120 until the hinge opening degree is approximately in the desired position. Then, a coordinate measuring machine is used to measure the angle until the hinge opening angle measured by the coordinate measuring machine reaches the desired angle, at which point the locking member 150 is engaged. The adjusted hinge opening degree has an error of less than 0.1 degrees, improving the adjustment accuracy and simplifying the operation.

[0042] In this embodiment, the track 120 includes a first slide rail 122. The cross-section of the first slide rail 122 gradually decreases from the side facing the slider 130 to the side facing away from the slider 130. The slider 130 has a slide rail 132 that matches the shape of the first slide rail 122 and is slidably engaged on the first slide rail 122 via the slide rail 132. The track 120 includes a base 124. The side of the first slide rail 122 facing away from the slider 130 is connected to the base 124. Optionally, the first slide rail 122 and the base 124 are integrally formed.

[0043] Slider 130 has a buffer groove 134, see Figure 5 and Figure 6 The buffer groove 134 extends parallel to the slide rail 132, and the depth of the buffer groove 132 is not less than the depth of the slide rail 132. A buffer wall 136 is formed between the buffer groove 134 and the slide rail 132. The top of the buffer wall 136 is lower than the surface of the slider 130 opposite to the base 124. The buffer groove 134 increases the amplitude of the reciprocating deformation of the buffer wall 136 in the direction perpendicular to the first slide rail 122. The width of the buffer groove 134 is approximately equal to the width of the bottom of the buffer wall 136. The locking member 150 includes a locking knob 152. The outer side of the slider 130 has a threaded hole (not shown) extending to the buffer groove 134. One end of the locking knob 152, screwed into the threaded hole, passes through the buffer groove 134 and abuts against the inner wall of the buffer groove 134. Specifically, the locking knob 152 passes through the buffer groove 134 and abuts against the buffer wall 136. By tightening the locking knob 152, the buffer wall 136 is pressed against the first slide rail 122, thereby limiting relative movement. This also prevents the end of the locking knob 152 from directly contacting the first slide rail 122, which would cause wear and reduce the smoothness of the slide rail surface, thus improving the service life and sliding accuracy of the slide rail. Furthermore, the buffer wall 136 reduces the precision requirements for matching the first slide rail 122 and the slide rail 132 during production, lowering production difficulty and costs.

[0044] In this embodiment, the cross-sections of the first slide rail 122 and the slide channel 132 are isosceles trapezoids. When the locking knob 152 is adjusted so that its end presses against the buffer wall 136, the inner wall of the slide channel 132 moves relative to the outer wall of the first slide rail 122. Specifically, the slider 130 moves slightly toward the base 124. As the locking knob 152 gradually loosens, the slider 130 moves slightly toward the direction away from the base 124. Further loosening of the locking knob 152 allows the slider 130 to achieve a greater range of movement in the direction away from the base 124.

[0045] The track 120 also includes a second slide rail 126. The first slide rail 122 has a groove (not shown) on the side facing the slider 130 to receive and fix the second slide rail 126. The bottom of the slide rail 132 has a groove 138 that matches the second slide rail 126. The adjustment device of this utility model also includes an adjustment member 170, which includes a sleeve 172 and an adjustment rod 174 having a gear portion 1742. The adjustment rod 174 passes through the sleeve 172 and through the slider 130, and the gear portion 1742 is exposed at the bottom of the groove 138. The second slide rail 126 has a rack portion 1262 on the side opposite to the gear portion 1742 that meshes with the gear portion 1742. See [reference needed]. Figure 5Specifically, the slider 130 has a through hole passing through the bottom of the slide groove 138. The rod portion of the adjusting rod 174 passes through the sleeve 172 and is rotatably mounted in the through hole. The two ends of the sleeve 172 abut against the slider 130 and the cap portion of the adjusting rod 174, respectively. A gear portion 1742 is provided on the rod portion of the adjusting rod 174. The gear portion 1742 and the rack portion 1262 have a small tooth depth and a large tooth density, which is used for more precise adjustment. When measuring the opening degree of hinge 50, the top block 130 rests against the bottom side of the free end of the movable page 52 of hinge 50. The locking knob 152 is loosened until the gear part 1742 of the adjusting rod 174 disengages from the rack part 1262 of the second slide rail 126. The sleeve 172 is pushed to make the slider 130 slide to the approximate position where the hinge opening degree is at the desired value. Then the locking knob 152 is tightened. During the tightening of the locking knob 152, the buffer wall 136 gradually squeezes the first slide rail 122 and moves laterally slightly, so that the gear part 1742 and the rack part 1262 gradually mesh. When measuring the hinge opening degree using a coordinate measuring machine, the tightness of the locking knob 152 is adjusted. After rotating the adjusting rod 174 to the desired value, the locking knob is tightened. This can obtain a hinge opening degree with an error of less than 0.1 degrees, improving the accuracy of the hinge coordinate measuring machine measurement data. Optionally, the length of the rack portion 1262 is less than or equal to the length of the slider 130 extending along the first slide rail 122. When measuring different opening degrees of the hinge, the height can be adjusted by the heightening block 160, and the length of the track 120 can be adjusted by adjusting the relative position of the second slide rail 126 in the groove while keeping the gear portion 1742 and the rack portion 1262 relative. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

[0046] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
