Description

Technical Field

[0001] The invention relates to the technical field of automobile sunroof equipment, and in particular to a guide linkage device for an automobile sunroof. Background Art

[0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car and increase the intake of fresh air. In order to drive the car sunroof to slide on the roof, a driving mechanism, a motion mechanism and a carrier for the sunroof panel to be installed are required. The driving mechanism provides power, and the motion mechanism guides the carrier to complete the lifting, sliding and other actions;

[0003] At present, a sunroof driving device in the prior art is provided with a guide connecting plate on a carrier, and a driving slide is provided on the guide connecting plate. The driving slide slides on a guide rail. During the process, the driving slide acts on the guide connecting plate, and controls the lifting, opening and closing of the carrier through the curved trajectory on the guide connecting plate. After reaching the end of the guide connecting plate, the carrier completes sinking, and then the driving slide continues to run to drive the sunroof to fully open. The problem with the above-mentioned roof is that a random recess is provided at the end of the guide connecting plate, and two guide elements are provided on the driving slide. When the driving slide drives the sunroof, the guide element must be completely placed in the random recess. The positioning requirements and the overall precision requirements for the guide connecting plate and the guide element are relatively high. Deviations are likely to occur between the guide element and the random recess, resulting in jamming of the sunroof, or partial entry of the guide element, or a gap between the guide element and the random recess, which is likely to cause abnormal noise and sunroof jamming. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a guide linkage device for a car sunroof to ensure the stability of the sunroof state switching and operation opening.

[0005] The above technical purpose of the present invention is achieved through the following technical solutions: a guide linkage device for a car sunroof, comprising a guide rail and a carrier for carrying the sunroof, the guide rail is also provided with a driving skeleton for driving the carrier to move and return relative to the guide rail, the driving skeleton is constrained to slide in the travel channel of the guide rail, the carrier is provided with guide ribs for the driving skeleton to move thereon, the guide ribs are in a curved trajectory, and the driving skeleton is provided with a guide unit that is always attached to the upper and lower ends of the guide ribs, the guide ribs include at least a first section for driving the carrier to rise and a second section for driving the carrier to sink, and the second section forms a vertically inclined slope at the end of the first section, the guide unit is guided into the second section by the first section, and the driving skeleton continues to move to drive the carrier to move.

[0006] Furthermore, the second section extends to the upper part of the carrier in a straight line, and the rear part of the second section is open.

[0007] Furthermore, the second section is connected to the first section by an arc-shaped transition.

[0008] Furthermore, the guide unit includes: a first guide element, which acts on the upper end surface of the guide rib, and the first guide element is provided with a guide arc surface; a second guide element, which acts on the lower end surface of the guide rib, and the first guide element is provided with a supporting foot that fits the contour of the lower end surface of the second section.

[0009] Furthermore, the first guide element and the second guide element are arranged on the driving frame in a staggered manner front to back.

[0010] Furthermore, the width of the connection between the first section and the second section is greater than the width of both sides thereof.

[0011] Furthermore, a first limit block is provided on the pivot end near the carrier, a second limit block is provided near the rear end of the carrier, and a guide component is also provided on the travel channel for guiding the first limit block and the second limit block to switch between the tilted state and the sunken state of the carrier.

[0012] Furthermore, the guide component includes a first guide block and a second guide block which are relatively arranged at the front and rear ends of the travel channel, and the first guide block and the second guide block are separately arranged relative to the guide rail.

[0013] Furthermore, after the carrier reaches the sinking state, the first limit block and the second limit block are guided by the guide component to slide in the travel channel.

[0014] Furthermore, the guide component is provided with a guide channel for the first limit block and / or the second limit block to run therein, and slots are provided on both sides of the guide channel; the guide rail is provided with an installation groove for the guide component to be inserted, and protrusions are provided on both sides of the installation groove, and the protrusions are plugged into and matched with the slots.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: during operation, the driving skeleton first runs on the first section of the guide rib and completes the tilting action of the carrier. When the guide unit reaches between the first section and the second section, the arc portion between the two guides the guide unit to enter the second section. The second section has an upward slope relative to the first section. As the driving skeleton runs on the second section, the relative height between the driving skeleton and the guide rail remains unchanged, causing the carrier to sink. During the cooperation between the guide unit and the second section, the rear part of the second section is set to be open, thereby ensuring that the guide unit can stably enter the second section and maintain action and cooperation with it, thereby reducing the overall manufacturing difficulty and reducing the shaking and jamming of the guide unit on the second section during the operation of the sunroof. At the same time, when the guide unit runs to the second section, the supporting feet on the second guide element fit the contour of the second section, eliminating the gap between the first guide element and the second guide element on the second section during the movement, thereby increasing the stability of the sunroof operation.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0025] It should be understood that although the terms upper, middle, lower, top, end, etc. appear in this article to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, and are not used to define any direction or order limitation.

[0026] like Figure 1-7 As shown, a guide linkage device for a car sunroof includes a guide rail 1 and a carrier 2 for carrying the sunroof. A driving skeleton 3 is also provided on the rail, and the driving skeleton 3 is used to drive the carrier 2 to move and return on the guide rail 1, so that the sunroof can be opened and closed relative to the roof.

[0027] Before the sunroof is fully opened, the sunroof needs to be lifted up first, and then the sunroof sinks down after the lifting is completed through the hinge end of the carrier 2, and then enters the opening process. The guide rail 1 is provided with a travel channel 1.1, and the driving frame 3 is constrained to slide in the travel channel 1.1, so as to constrain the relative height between the driving frame 3 and the guide rail 1 to remain unchanged. The carrier 2 is provided with a guide rib 2.1 for the driving frame 3 to travel thereon, and the guide rib 2.1 is a curved track, and the driving frame 3 is provided with a guide unit that is always attached to the upper and lower ends of the guide rib 2.1, and the guide rib 2.1 at least includes a guide rib 2.1 for The first section 2.2 is used to drive the carrier 2 to tilt up, and the second section 2.3 is used to drive the carrier 2 to sink down, and the second section 2.3 forms a vertically inclined slope at the end of the first section 2.2. After the guide unit moves to the end of the first section 2.2, the carrier 2 completes tilting. At the same time, the guide unit is guided by the first section 2.2 to enter the second section 2.3. When the guide unit moves on the second section 2.3, the carrier 2 gradually sinks and completes the sinking at the end of the second section 2.3. The front and rear ends of the carrier 2 enter the travel channel 1.1 of the guide rail 1. After that, the driving skeleton 3 continues to move to drive the carrier 2 to move.

[0028] As a preferred embodiment, the guide ribs 2.1 are arranged on both sides of the carrier 2 along the longitudinal direction of the roof, and the guide units on the driving frame 3 are also covered on the guide ribs 2.1 on both sides of the carrier 2.

[0029] As an embodiment, the second section 2.3 is vertically inclined with respect to the first section 2.2, which means that the second section 2.3 and the first section 2.2 form a relative angle, which is set to be an obtuse angle to alleviate the height difference between the second section 2.3 and the first section 2.2, and the end of the second section 2.3 has a tendency to lift upward.

[0030] like Figure 1 As shown in , in order to enable the guide unit to stably enter the second section 2.3, the second section 2.3 extends to the upper part of the carrier 2 in a straight line, and the rear of the second section 2.3 is open, thereby facilitating the positioning of the guide unit and the second section 2.3.

[0031] In other embodiments, those skilled in the art may conceive, based on the above, that the second section 2.3 may be a curved line, which ultimately drives the skeleton 3 to drive the carrier 2 to sink.

[0032] Specifically, the arc-shaped transition connection between the second section 2.3 and the first section 2.2 enables the guide unit to smoothly enter the second section 2.3 and return from the second section 2.3 to the first section 2.2. Preferably, an arc portion 2.4 is formed between the first section 2.2 and the second section 2.3, and the lower end surface of the arc portion 2.4 has a smoother arc surface than the upper end surface of the arc portion 2.4.

[0033] Specifically, the guide unit includes: a first guide element 3.1, which acts on the upper end surface of the guide rib 2.1, and the first guide element 3.1 is provided with a guide arc surface 3.1.1; a second guide element 3.2, which acts on the lower end surface of the guide rib 2.1, and the first guide element 3.1 is provided with a supporting foot 3.2.1 that fits the contour of the lower end surface of the second section 2.3, and the supporting foot 3.2.1 has an inclined surface that fits the lower contour of the second section 2.3.

[0034] In order to increase the tightness of the guide unit on the guide rib 2.1, the first guide element 3.1 and the second guide element 3.2 are arranged on the driving skeleton 3 in an alternating manner front and back. At the same time, in order to ensure the stability of both the carrier 2 and the driving skeleton 3 when the guide unit moves on the guide rib 2.1, the width of the connection between the first section 2.2 and the second section 2.3 is larger than the width on both sides thereof, and the width of the first section 2.2 near its end is larger than the width of its initial end. In this way, when the guide unit moves from the first section 2.2 to the second section 2.3, the second guide element 3.2 is always at the rear of the first guide element 3.1, so that the second guide element 3.2 enters the second section 2.3 before the first guide element 3.1, and provides auxiliary support for the first guide element 3.1, thereby increasing the stability of the carrier 2 when it sinks and returns, and reducing the sense of frustration caused by the height difference.

[0035] like Figure 2-Figure 5 As shown, a first limit block 2.5 is provided on the pivot end near the carrier 2, a second limit block 2.6 is provided near the rear end of the carrier 2, and a guide component is also provided on the travel channel 1.1 for guiding the first limit block 2.5 and the second limit block 2.6 to switch between the tilted state and the sunken state of the carrier 2.

[0036] Specifically, the guide component includes a first guide block 1.2 and a second guide block 1.3 which are relatively arranged at the front and rear ends of the travel channel 1.1, wherein the first guide block 1.2 is arranged on one side of the carrier 2 and is provided for the first limit block 2.5 to be placed therein, and the second guide block 1.3 is arranged on the other side of the carrier 2 and is provided for the second limit block 2.6 to be placed therein, and the first guide block 1.2 and the second guide block 1.3 are separately arranged relative to the guide rail 1, thereby facilitating the molding of the guide rail 1, reducing the manufacturing difficulty, and facilitating the positioning and matching with the actual size of the carrier 2.

[0037] Specifically, after the carrier 2 reaches the sinking state, the first limit block 2.5 and the second limit block 2.6 are guided by the guide component to slide in the travel channel 1.1.

[0038] Specifically, the second guide block 1.3 is provided with a guide channel 1.4 for the second limit block 2.6 to run therein. Optionally, the first guide block 1.2 is provided with a guide channel 1.4 for the first limit block 2.5 to run therein. The guide channel 1.4 is used for the first limit block 2.5 and the second limit block 2.6 to slide therein in at least two of the actions of the carrier 2 lifting, lifting and returning, sinking and sinking and returning, so as to ensure the stability of the movement of the carrier 2.

[0039] Among them, slots 1.5 are provided on both sides of the guide channel 1.4 located on the second guide block 1.3; the guide rail 1 is provided with a mounting groove 1.6 for inserting the guide component, and protrusions 1.7 are provided on both sides of the mounting groove 1.6, and the protrusions 1.7 are plugged into the slots 1.5.

[0040] As a configuration mode of the guide rib 2 . 1 , the guide rib 2 . 1 is a covering part formed on the lower part of the carrier 2 .

[0041] During operation, the driving skeleton 3 first runs on the first section 2.2 of the guide rib 2.1 and completes the tilting action of the carrier 2. When the guide unit reaches between the first section 2.2 and the second section 2.3, the arc portion 2.4 between the two guides the guide unit to enter the second section 2.3. The second section 2.3 has an upward slope relative to the first section 2.2. As the driving skeleton 3 runs on the second section 2.3, the relative height between the driving skeleton 3 and the guide rail 1 remains unchanged, so that the carrier 2 sinks. In the process of cooperation between the guide unit and the second section 2.3, The rear portion of the second section 2.3 is set to be open, thereby ensuring that the guide unit can stably enter the second section 2.3 and maintain interaction and cooperation with it, reducing the overall manufacturing difficulty and reducing the shaking and jamming of the guide unit on the second section 2.3 during the operation of the sunroof. At the same time, when the guide unit runs to the second section 2.3, the supporting foot 3.2.1 on the second guide element 3.2 fits the contour of the second section 2.3, eliminating the gap between the first guide element 3.1 and the second guide element 3.2 on the second section 2.3 during the movement, thereby increasing the stability of the sunroof operation.

[0042] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
