Description

Technical Field

[0001] The utility model belongs to the technical field of automobile sunroofs, and in particular relates to an enclosed mechanical group cable assembly structure for automobile sunroofs. Background Art

[0002] With the development of the new energy vehicle market, automotive sunroofs are increasingly being used on the roofs of commercial SUVs and sedans. Most sunroof glass features opening and tilting functions, improving interior brightness, ensuring fresh air circulation, and enhancing passenger comfort. The sunroof glass is mounted on a motion mechanism. A motor transmits force to the mechanism via a cable, which in turn activates the movement of the sunroof, enabling it to open, close, and tilt.

[0003] The existing motion mechanism is complex, and the matching of various components is particularly important. This is especially true for the front guide and cable assembly. This can easily lead to malfunctions, unusual noises, and vibrations of the sunroof glass. During high-speed collision tests (i.e., simulated car crashes), this assembly transmits the vast majority of the impact force generated by the glass's inertia. Therefore, this assembly must be sufficiently strong to ensure the sunroof maintains normal operation under extreme acceleration during high-speed collisions. Summary of the Invention

[0004] The purpose of the utility model is to solve the above technical problems and provide a car sunroof enclosed type mechanical group cable assembly structure with higher structural strength and safety.

[0005] To achieve the above-mentioned purpose, the utility model provides a car sunroof surrounded mechanical group cable assembly structure, including a sunroof cable head, a mechanical group front guide and a guide rail; the mechanical group front guide is embedded in the sunroof cable head, and the sunroof cable head cooperates with the slide groove of the guide rail, and the mechanical group front guide cooperates with the upper surface of the guide rail.

[0006] Furthermore, the sunroof cable head includes a thin iron body, a thin iron plastic part of the plastic-coated thin iron body, and a core wire. One end of the thin iron body is curled inward to form a thin iron through hole for inserting the core wire, and the inward curled part of the thin iron is stuck in the slide groove of the guide rail.

[0007] Furthermore, the front guide of the mechanical group includes an iron body, a mechanical group plastic part of the plastic-coated iron body, and a rubber block; an elastic seat is arranged on the surface of the outward protruding part of the side of the mechanical group plastic part, and the rubber block is built into the installation cavity of the elastic seat. When the front guide of the mechanical group runs in the guide rail, the outer surface of the elastic seat contacts the upper surface of the guide rail.

[0008] Furthermore, an embedding notch is provided in the middle of the head of the sunroof cable, and the outwardly protruding portion of the side of the mechanical assembly plastic part and the elastic seat are embedded in the embedding notch.

[0009] Furthermore, the upper and lower surfaces of the thin iron-plastic part respectively abut against the upper and lower surfaces of the guide rail 3 .

[0010] Furthermore, a connecting rib is provided at the edge of the head of the skylight cable and above the embedding notch, and the connecting rib surrounds the embedding notch into a circular shape.

[0011] Furthermore, the surface of the elastic seat in contact with the upper surface of the guide rail is an arc-shaped surface.

[0012] Furthermore, the embedding gap is surrounded by a circle of thin iron.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention adopts a structure in which the front guide of the mechanical group is embedded in the head of the sunroof cable, which enhances the strength of the head of the sunroof cable, thereby improving the strength of the mechanical group transmission structure; in addition, a rubber block is added to the Z direction of the front guide of the mechanical group to ensure the vertical stability of the front guide of the mechanical group in the guide rail, avoid overturning and generating abnormal noise during operation, and ensure that the sunroof can operate normally during high-speed collision tests, thereby increasing the safety performance of the sunroof.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1The illustrated vehicle sunroof enclosed mechanical assembly cable assembly structure includes a sunroof cable head 1, a mechanical assembly front guide 2, and a guide rail 3. The mechanical assembly front guide 2 is embedded in the sunroof cable head 1, which engages with a guide groove 3.1 of the guide rail 3, and the mechanical assembly front guide 2 engages with the upper surface of the guide rail 3. This enhances the fit between the mechanical assembly front guide and the sunroof cable head, preventing the mechanical structure from colliding with the mechanical assembly at high speed during movement, or causing the sunroof cable to break, thereby causing the sunroof to malfunction. The guide rail provides a stable motion path for the mechanical assembly front guide and the sunroof cable head.

[0022] like Figure 2 The sunroof cable head 1 shown in the figure comprises a thin iron body 1.1, a thin iron plastic part 1.2 coated with plastic within the thin iron body 1.1, and a core wire 1.3. One end of the thin iron body 1.1 is curled inward to form a thin iron through-hole 1.4 for the core wire 1.3 to be inserted. The thin iron body strengthens the transmission of force from the sunroof cable head and absorbs collision forces. The mechanical assembly front guide 2 comprises an iron body 2.1, a mechanical assembly plastic part 2.2 coated with plastic within the iron body 2.1, and a rubber block 2.3. An elastic seat 2.5 is arranged on the surface of an outwardly protruding portion 2.4 on the side of the mechanical assembly plastic part 2.2, and the rubber block 2.3 is embedded in a mounting cavity 2.6 within the elastic seat 2.5.

[0023] like Figure 3 、 4 As shown in Figures 5 and 6, there is an embedding notch 1.5 in the middle of the sunroof cable head 1, and the side outward protrusion 2.4 and the elastic seat 2.5 of the mechanical group plastic part 1.2 are embedded in the embedding notch 1.5, which plays the role of transmitting the force of the sunroof cable head and bearing the collision force; the inward curled part of the thin iron body 1.1 is stuck in the slide groove 3.1 of the guide rail 3, and when the front guide 2 of the mechanical group runs in the guide rail 3, the outer surface of the elastic seat 2.5 contacts the upper surface of the guide rail 3, which plays a buffering role, avoiding the defect of jumping of the front guide of the mechanical group due to unstable movement during operation; at the same time, the upper and lower surfaces of the thin iron plastic part 1.2 respectively rest against the upper and lower surfaces of the guide rail 3 to ensure the stability of the movement of the sunroof cable head 1 and the force transmission during collision, thereby preventing structural damage.

[0024] In addition, there is a connecting rib 1.6 at the edge of the sunroof cable head 1 and above the embedding notch. The connecting rib 1.6 surrounds the embedding notch 1.5 into a circular shape to enhance the connecting force and pulling force in the front-to-back direction, preventing the sunroof cable head 1 from deforming in the front-to-back direction during a collision.

[0025] The surface where the elastic seat 2.5 contacts the upper surface of the guide rail 3 is an arc-shaped surface; the embedded notch 1.5 is surrounded by a circle of thin iron, which can greatly enhance the strength of the sunroof cable head to ensure that the transmission structure does not break in the event of a high-speed collision (simulating a high-speed car accident experiment), meeting the normal functions of the sunroof such as lifting, opening, and closing, and ensuring safety performance.

[0026] During assembly of the mechanical assembly, the raised front guide portion is fitted with an elastic seat that slots into the notch in the center of the sunroof cable head. A motor transmits force from the front guide structure to the mechanical assembly via a flexible shaft, and the movement of the mechanical assembly activates the opening, closing, and tilting of the glass. A surrounding thin iron reinforcement strengthens the entire sunroof cable head, ensuring that the transmission structure does not break in the event of a collision, preventing the sunroof glass from flying out. Rubber blocks embedded in the elastic seat of the mechanical assembly's plastic components act as vertical buffers, ensuring stable operation of the front guide within the guide rails.

[0027] When the vehicle is traveling at high speed, if an unexpected collision occurs, the sunroof must also be able to operate normally. When the vehicle is traveling at high speed and an unexpected collision occurs, or when the vehicle is started or braked suddenly, the vehicle will generate a large acceleration. At this time, the connection between the mechanical group and the sunroof cable must be strong enough to ensure that the force can be normally transmitted to the mechanical group to complete the opening or closing function of the sunroof, and avoid the sunroof mechanical group structure from breaking and failing, causing the sunroof glass to not work properly. This practical vehicle model increases the contact and cooperation between the sunroof cable head and the front guide of the mechanical group in the direction of operation, thereby enhancing the strength of the mechanical group transmission structure. A buffer structure is added to the vertical direction of the front guide of the mechanical group to ensure the Z-direction stability of the front guide of the mechanical group in the guide rail, which plays a more reliable role in the transmission between the two parts and avoids the flexible operation in the vertical direction causing reversal and abnormal noise during operation.
