Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, and in particular to a mushroom-shaped latch detection and pressing mechanism for an automotive sunroof assembly. Background Technology

[0002] With the development of the automotive industry and consumers' increasing demands for vehicle comfort, sunroofs have become standard equipment on mid-to-high-end models. Mushroom-shaped hooks are typically used to secure sunroof sunshades, and their assembly quality directly affects the sunroof's sealing performance, noise control, and durability. Incorrect placement or loose adhesion of the mushroom-shaped hooks during sunroof assembly can lead to poor sealing or abnormal noises while driving.

[0003] The current assembly of mushroom-shaped hook-and-loop fasteners is generally done manually by pasting and pressing, which is inefficient and results in inconsistent pressing pressure. The position detection of the hook-and-loop fasteners relies on visual inspection, which is difficult to discern visually because the fasteners and the attached components are mostly black and located on the lower surface of the sunroof. This leads to low detection efficiency and a high rate of missed detections. In short, existing mushroom-shaped hook-and-loop fastener pressing detection devices suffer from low efficiency and a high rate of missed detections. Utility Model Content

[0004] The purpose of this invention is to provide a mushroom-shaped latch detection and pressing mechanism for automotive sunroof assemblies, which can solve the technical problems of low operating efficiency and high missed detection rate of existing mushroom-shaped latch pressing and testing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model discloses a mushroom-shaped latch detection and pressing mechanism for an automotive sunroof assembly, comprising a detection and pressing component, a housing, and a cylinder assembly. The interior of the outer shell is a cavity structure, and the detection and pressing component is disposed inside the cavity of the outer shell. The detection pressing component is positioned above the cylinder assembly, and its bottom is connected to the piston rod of the cylinder assembly. The piston rod drives the detection pressing component to move up and down. When the detection pressing component moves upward, its top contacts the bottom of the mushroom-shaped hook and releases pressure to detect the installation position of the hook and release and ensure the installation force.

[0006] As a preferred embodiment, the detection pressing assembly includes a detection pin, a return spring, a contour detection block, and two detection sensors. The top of the contour detection block has a vertical mounting hole, and the detection pin and return spring are sequentially arranged within the mounting hole from top to bottom. The two detection sensors are respectively located on both sides of the contour detection block. The detection pin has a transverse detection hole, and the side of the contour detection block has a through hole parallel to the central axis of the detection hole. The two detection sensors have through holes with the same central axis as the through hole. When the top of the detection pin is not pressed, the central axes of the detection hole, through hole, and through hole are aligned, allowing the through light emitted by the two detection sensors to pass smoothly through the detection hole. When the top of the detection pin is pressed, the central axis of the detection hole is lower than the central axes of the through hole and through hole, preventing the through light emitted by the two detection sensors from passing through the detection hole.

[0007] Furthermore, the detection pressing assembly also includes an upper guide pin and a lower guide pin. The detection pin has an upper pin hole along its longitudinal direction, and the upper guide pin is installed in the upper pin hole. The contour detection block has a lower pin hole along its longitudinal direction, and the lower guide pin is installed in the lower pin hole.

[0008] Furthermore, the contour detection block has an upper waist groove along the vertical direction, the opening of which corresponds to the opening of the upper pin hole, allowing the upper guide pin to move up and down within the upper waist groove; the outer shell has a lower waist groove along the vertical direction, the opening of which corresponds to the opening of the lower pin hole, allowing the lower guide pin to move up and down within the lower waist groove. The upper and lower guide pins, under the action of their waist-shaped grooves, can constrain the detection pressing component to only move up and down, preventing it from rotating.

[0009] Furthermore, the top of the contour detection block is provided with a horizontal groove that matches the shape of a mushroom-shaped hook and loop fastener, and the mounting hole is located in the horizontal groove.

[0010] As a preferred embodiment, the cylinder assembly includes a cylinder body and a cylinder floating joint. The cylinder floating joint is vertically disposed on the top of the cylinder body. The top of the piston rod inside the cylinder body is connected to the bottom of the cylinder floating joint, thereby connecting the piston rod to the detection and pressing component through the cylinder floating joint.

[0011] As a preferred embodiment, the detection pressing mechanism further includes a mounting base disposed below the cylinder assembly.

[0012] The beneficial effects of this utility model are: This utility model provides a mushroom-shaped latch detection and pressing mechanism for automotive sunroof assemblies. A piston rod of a cylinder drives a detection and pressing component to move up and down within the housing. When the detection and pressing component moves upward, its top contacts the bottom of the mushroom-shaped latch and further presses it down, thus detecting the latch's installation position and ensuring the correct installation force. This automotive sunroof mushroom-shaped latch detection mechanism can accurately detect the latch's position and precisely control the pressing force, enabling automatic detection and pressing of the latch's position. Compared to manual visual inspection, this significantly improves work efficiency and greatly reduces the missed detection rate. Furthermore, compared to manual pressing, it reduces manual labor intensity and increases work efficiency. Attached Figure Description

It should be understood that the specific embodiments described herein are only for explaining this utility model and not for limiting it.

For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] This utility model relates to a mushroom-shaped latch detection and pressing mechanism for automotive sunroof assemblies. This automotive sunroof mushroom-shaped latch detection device can accurately detect the position of the latch and precisely control the pressing pressure, enabling automatic detection and pressing of the latch position. Compared to manual visual inspection of the latch position, it greatly improves work efficiency and significantly reduces the missed detection rate. Simultaneously, compared to manual pressing, it reduces manual labor intensity and improves work efficiency. In this utility model, X-axis is defined as longitudinal, Y-axis as transverse, and Z-axis as vertical. Figure 1 As shown.

[0025] like Figure 1 , 3As shown, this utility model provides a mushroom-shaped latch detection and pressing mechanism for an automotive sunroof assembly, including a detection and pressing component 1, a housing 2, a cylinder assembly 3, and a mounting base 4. The housing 2 has a hollow cavity structure, and the detection and pressing component 1 is disposed within the cavity of the housing 2. The detection and pressing component 1 is positioned above the cylinder assembly 3, and its bottom is connected to the piston rod 32 of the cylinder assembly 3. The piston rod 32 drives the detection and pressing component 1 to move up and down. When the detection and pressing component 1 moves upward, its top contacts the bottom of the mushroom-shaped latch and further presses it, thereby detecting the installation position of the mushroom-shaped latch and ensuring the installation force. The mounting base 4 is positioned below the cylinder assembly 3.

[0026] like Figure 2-3 As shown, the detection pressing assembly 1 includes a detection pin 11, a return spring 12, a contour detection block 13, two detection sensors 14, an upper guide pin 15, and a lower guide pin 16. The top of the contour detection block 13 has a mounting hole 105 along the vertical direction. The detection pin 11 and the return spring 12 are arranged sequentially from top to bottom in the mounting hole 105. The two detection sensors 14 are respectively arranged on both sides of the contour detection block 13. The detection pin 11 has a detection hole 101 along the horizontal direction. The side of the contour detection block 13 has a through hole 104 parallel to the central axis of the detection hole 101. The two detection sensors 14 have through holes 108 coaxial with the central axis of the through hole 104. When the top of the detection pin 11 is not pressed, the central axes of the three holes—detection hole 101, through hole 104, and through-hole 108—are aligned, allowing the through-beams emitted by the two detection sensors 14 to pass smoothly through the detection hole 101. When the top of the detection pin 11 is pressed, the central axis of the detection hole 101 is lower than the central axes of the through hole 104 and through-hole 108, preventing the through-beams emitted by the two detection sensors 14 from passing through the detection hole 101. The detection pin 11 has an upper pin hole 102 along its longitudinal direction, and an upper guide pin 15 is installed in the upper pin hole 102. The contour detection block 13 has a lower pin hole 107 along its longitudinal direction, and a lower guide pin 16 is installed in the lower pin hole 107. The contour detection block 13 has an upper waist groove 106 along its vertical direction. The opening of the upper waist groove 106 corresponds to the opening of the upper pin hole 102, and the upper guide pin 15 moves up and down within the upper waist groove 106. The outer shell 2 has a lower waist groove 21 along its vertical direction. The opening of the lower waist groove 21 corresponds to the opening of the lower pin hole 107, and the lower guide pin 16 moves up and down within the lower waist groove 21. Under the action of its waist-shaped groove, the upper and lower guide pins 16 can constrain the detection pressing component 1 to only move up and down, preventing it from rotating. The top of the contour detection block 13 also has a horizontal groove 103 that matches the shape of the mushroom-shaped hook and loop fastener, and the mounting hole 105 is set in the horizontal groove 103. The contour detection block 13 covers the mushroom-shaped hook and loop fastener through the top horizontal groove 103 for positioning.

[0027] like Figure 3-5As shown, the cylinder assembly 3 includes a cylinder body 31 and a cylinder floating joint 33. The cylinder floating joint 33 is arranged vertically on the top of the cylinder body 31. The top of the piston rod 32 inside the cylinder body 31 is connected to the bottom of the cylinder floating joint 33. The piston rod 32 is connected to the detection and pressing assembly 1 through the cylinder floating joint 33.

[0028] This pressing mechanism is primarily used to check the correct installation position of the mushroom-shaped latches at the bottom of the automotive sunroof assembly, while also pressing the latches to ensure a more secure installation. This pressing mechanism is also suitable for other components requiring pressing tests. Its working process is as follows: The sunroof assembly is manually placed onto the positioning and contouring fixture, and the positioning pins are inserted to initially position the assembly. Then, the front and rear sunroof panels are clamped by a clamping cylinder. The telescopic cylinder of the mushroom-shaped hook-and-loop fastener detection and pressing mechanism extends and presses the mushroom-shaped hook-and-loop fasteners installed at the bottom of the sunroof assembly to check if the fasteners are correctly positioned and to ensure proper installation force. If the fasteners are incorrectly positioned, the detection and pressing mechanism will sound an alarm. If the fasteners are correctly positioned, the detection and pressing mechanism presses them firmly to ensure they are securely attached. Then, the clamping cylinder releases, and the sunroof assembly is manually removed, completing the mushroom-shaped hook-and-loop fastener detection and pressing process.

[0029] 1. The detection pressing mechanism consists of a detection pressing component, a housing, a cylinder assembly, and a mounting base, such as... Figure 1 , 3 As shown. This mechanism has two functions: first, to detect the position of the mushroom-shaped hook and loop fastener; second, to press the hook and loop fastener to ensure it is securely fastened. The functions of each component are as follows: a) The detection pressing assembly consists of a detection pin, an upper guide pin, a return spring, a contour detection block, a detection sensor, and a lower guide pin. When the detection pressing assembly is in operation, it is extended by the piston rod of the telescopic cylinder. When extended, the mushroom-shaped detection block covers the mushroom-shaped hook and loop fastener through the top transverse groove, and the top of the detection pin is pressed by the mushroom-shaped hook and loop fastener.

[0030] like Figure 5 , 6 As shown, if the mushroom-shaped latches of the sunroof assembly are missing or misaligned, the top of the detection pin will not be pressed down by the latches, and the detection pin will not retract into the detection pressing mechanism. At this time, the central axes of the three holes—the detection hole, the through hole, and the through-beam hole—are aligned, and the through-beam laser emitted by the two detection sensors can pass smoothly through the detection hole, allowing the detection sensors to receive the through-beam laser. Figure 5 , 6 The red dashed line in the middle indicates the received laser beam.

[0031] like Figure 7As shown, if the mushroom-shaped latch is correctly installed at the bottom of the sunroof assembly, the top of the detection pin will be pressed down by the mushroom-shaped latch. The detection pin will then compress the return spring downwards, causing the detection pin to retract into the detection pressing mechanism. At this time, the central axis of the detection hole is lower than the central axis of the through hole and the through-hole. The through-laser emitted by the two detection sensors cannot pass through the detection hole, and the detection sensors cannot receive the through-laser.

[0032] The system automatically determines whether the mushroom-shaped latches of the sunroof assembly are installed correctly by detecting whether the sensors receive the laser beam, and determines whether to issue an alarm notification based on the detection sensors.

[0033] b) The outer casing is used to connect the mushroom hook and loop detector pressing assembly, the telescopic cylinder assembly, and the mounting base. The lower guide pin, under the action of the lower waist groove of the outer casing, can constrain the mushroom hook and loop detector pressing assembly to move vertically up and down, preventing it from rotating laterally and thus affecting the accuracy of the mushroom hook and loop position detection.

[0034] c) The telescopic cylinder assembly consists of a cylinder body, a cylinder floating joint, and a cylinder sensor. It drives the movement of the mushroom-shaped hook-and-loop fastener detection and pressing component. A precision pressure regulating valve controls the adjustment of the pressing force on the hook-and-loop fastener, achieving good consistency in pressing force. The cylinder floating joint connects the cylinder piston rod to the mushroom-shaped hook-and-loop fastener detection and pressing component. The cylinder sensor detects the extension and retraction state of the cylinder piston rod.

[0035] d) Mounting base, located below the telescopic cylinder assembly, for connecting the mushroom hook and loop detector pressing mechanism and the detection base plate.

[0036] 2. Positioning assembly, consisting of positioning pins and positioning contouring fixtures. The positioning pins engage with the left and right guide rails of the sunroof, as well as the positioning holes for the front and rear rows. The positioning contouring fixtures support the bottom of the front row of the sunroof, providing positioning support and controlling the vertical height of the front row.

[0037] 3. The clamping assembly consists of a clamping cylinder and a positioning support. The positioning support supports the bottom of the rear sunroof, preventing deformation of the sunroof during the clamping cylinder's operation and thus avoiding displacement of the Hook and Loop fasteners. The clamping cylinder clamps the sunroof assembly, fixing its position and ensuring that the Hook and Loop fastener detection and pressing mechanism does not push the sunroof assembly out during upward pressing.

[0038] All other undescribed parts belong to the prior art. The above-described embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made 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 patent should be determined by the appended claims.
