Description

Technical Field

[0001] This utility model relates to the field of automotive sunroof technology, specifically to a motion mechanism for an automotive sunroof. Background Technology

[0002] Traditional automotive sunroof mechanisms include a glass mounting bracket, with a front support arm and a rear support arm hinged to its front and rear ends, respectively. The front support arm and the front slider form a multi-locking motion, as do the rear support arm and the drive slider. The front slider and the drive slider are connected via a multi-locking mechanism. A flexible shaft that drives the drive slider is fixedly engaged with it. In this design, the front and rear support arms are hinged to the front and drive sliders (rear sliders), respectively, and the front and drive sliders (rear sliders) are connected via a multi-locking mechanism. Examples include "CN 107433840 B A Panoramic Sunroof for Automotive Interiors" and "CN 211280602 U". The traditional car sunroof motion mechanism has many moving structural components, which increases the probability of mechanical problems. In order to maintain balance, the front slider and the drive slider (rear slider) are unstable during sliding in the guide rail. Both the front slider and the drive slider (rear slider) need to be equipped with guide feet on both sides, which increases the probability of mechanical noise. Even if the wobbling and swing amplitude of the front slider and the drive slider (rear slider) relative to the guide rail can be kept stable, the increase in the mechanism will increase the probability of mechanical noise. Utility Model Content

[0003] The purpose of this utility model is to provide a motion mechanism for an automotive sunroof, which has the advantages of fewer mechanical parts, lower cost, simple structure, better noise control, convenient assembly and installation, and easy disassembly and maintenance.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a motion mechanism for an automobile sunroof, comprising a glass fixing bracket, wherein a front support arm and a rear support arm are respectively hinged to the front and rear ends of the glass fixing bracket, a front slider is fixedly hinged to one end of the front support arm, a drive slider is connected to one end of the rear support arm, and a pull cable is installed at the front end of the glass fixing bracket and on the outside of the rear support arm.

[0005] As a preferred embodiment, the rear support arm and the drive slider are connected by a multiple locking device, and the front slider and the drive slider are connected by a hooked guide rod.

[0006] As a preferred embodiment, the front slider, the front support arm, and the non-hooked end of the hooked guide rod are hinged together.

[0007] As a preferred embodiment, the hook end of the hooked guide rod has a hook portion and a guide slider, and the guide slider of the hooked guide rod and the guide groove on the drive slider form a multi-locking motion.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. The main advantages of this utility model are that during the movement, there is no guide groove on the front slider, so the front slider is smaller in size. The front slider, the front support arm and the non-hook end of the hooked guide rod are hinged together. The hook end of the hooked guide rod has a hook and a guide slider. The guide slider of the hooked guide rod and the guide groove on the drive slider form a multi-locking motion. In addition, this device has fewer mechanical parts, lower cost, simple structure, better noise control, convenient assembly and installation, and easy disassembly and maintenance.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0015] Please see Figure 1-2 As shown, this utility model provides a motion mechanism for a car sunroof, including a glass fixing bracket 1. The front and rear ends of the glass fixing bracket 1 are respectively hinged to a front support arm 2 and a rear support arm 5. A front slider 3 is fixedly hinged to one end of the front support arm 2, and a drive slider 6 is connected to one end of the rear support arm 5. A pull cable 7 is installed at the front end of the glass fixing bracket 1 and on the outside of the rear support arm 5. Example 2:

[0016] Based on Embodiment 1, this utility model is as follows: Figure 1 As shown, the rear support arm 5 and the drive slider 6 are connected by a multi-locking device, and the front slider 3 and the drive slider 6 are connected by a hooked guide rod 4.

[0017] Adopting such Figure 1 The technical solution shown has a simple structure, good noise control, is easy to assemble and install, and is easy to disassemble and maintain.

[0018] Secondly, in the technical solution, the front slider 3, the front support arm 2, and the non-hook end of the hooked guide rod 4 are hinged together; the hook end of the hooked guide rod 4 has a hook and a guide slider, and the guide slider of the hooked guide rod 4 and the guide groove on the drive slider 6 form a multi-locking motion.

[0019] Its adoption is as follows Figure 1 The technical solution shown does not have a guide groove on the front slider 3, so the front slider 3 has a smaller volume.

[0020] The working principle of this utility model is as follows: When the skylight is opened, the flexible shaft drives the drive slider 6 to move backward. At this time, the front support arm 2 remains stationary, while the rear support arm 5 begins to tilt under the action of the drive slider 6. When the rear support arm 5 tilts to its highest point, the guide slider of the hooked guide rod 4 moves along the guide groove on the drive slider 6 to the front. The hook of the hooked guide rod 4 engages and locks with the locking hole on the guide foot of the drive slider 6. At this time, the front support arm 2 begins to tilt under the action of the hooked guide rod 4. Waiting for the front support arm 2 to rise to its highest point... The hook guide rod 4 moves backward together with the front support arm 2 and the rear support arm 5, which are located at the higher position, thus completing the opening of the sunroof. When the sunroof is closed, the flexible shaft moves forward with the drive slider 6. The hook guide rod 4 moves forward together with the front support arm 2 and the rear support arm 5, which are located at the higher position. The front support arm 2 moves down under the action of the brake. When the front support arm 2 moves down to the lowest point, the drive slider 6 still moves forward. At this time, the hook end of the hook guide rod 4 separates from the locking hole on the guide slide foot on the drive slider 6, and the drive slider 6 lowers with the rear support arm 5.
