Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a driving mechanism for controlling a skylight switch on an automobile. Background Art
[0002] At present, in order to meet the need of enjoying the scenery, the area of automobile skylights is getting larger and larger. When opening and closing the skylight and the sunshade, it is necessary to use a driving member to drive the flexible shaft to move through a connecting member connecting the driving member and the flexible shaft, so as to drive the skylight and the sunshade to open or close. However, since the area of the skylight is larger, when the driving member drives the skylight and the sunshade to move through the flexible shaft, the tensile force borne by the flexible shaft is also larger, resulting in the connecting member connecting the flexible shaft and the driving member being easily torn, and then the automobile skylight fails. Content of the Utility Model
[0003] In order to solve the problem that the automobile skylight fails due to the tearing of the connecting member connecting the flexible shaft and the driving member, the utility model provides a skylight driving mechanism, which includes a flexible shaft, a connecting member and a driving member. The connecting member is located between the flexible shaft and the driving member and connects the driving end of the flexible shaft and the driving member. The connecting member includes a metal member, the metal member is connected to the flexible shaft at the connecting end of the flexible shaft, and the surface of the metal member is coated with a plastic coating. In the skylight driving mechanism of the utility model, the connecting member is composed of a metal member and a plastic coating covering the surface of the metal member, which can effectively increase the strength of the connecting member, and then increase the pull-off force that the connecting member can bear, so as to reduce the probability of the automobile skylight failing due to the tearing of the connecting member in the skylight driving mechanism of the utility model.
[0004] Preferably, the flexible shaft includes a core wire, and a winding wire is wound around the core wire. In this way, the flexible shaft is formed by combining the core wire and the winding wire wound around the core wire, which can increase the strength and durability of the flexible shaft, and then extend the service life of the flexible shaft. Further, the winding wire is wound around the core wire by roll pressing. In this way, the winding wire is wound around the core wire by roll pressing, which can reduce the diameter of the flexible shaft on the basis of ensuring the strength and durability of the flexible shaft, meet the use requirements, and facilitate the flexible shaft to drive the skylight and the sunshade to move to complete the opening or closing operation under the drive of the driving member.
[0005] Preferably, a guiding head is arranged at the free end of the core wire away from the connecting member. In this way, arranging the guiding head at the free end of the core wire away from the connecting member can guide the flexible shaft during the movement process and facilitate the control of the movement path of the flexible shaft. Further, the guiding head is a conical shell, and the guiding head is sleeved on the free end of the core wire. Such a guiding head has a simple structure and is convenient and fast to manufacture, install and fix.
[0006] Preferably, in the connecting member, the metal member is coated on the connecting end of the core wire close to the driving member and riveted to the connecting end of the core wire, and a connecting card slot for connecting with the driving end of the driving member is arranged on the plastic coating layer. In this way, in the connecting member, the metal member is connected to the connecting end of the core wire by riveting, which is simple, convenient and stable; the connecting card slot is arranged on the plastic coating layer, which is convenient for connecting with the driving end of the driving member. Further, the metal member is formed by folding a metal sheet, a through hole is arranged on the metal member, and a clamping groove for clamping the plastic coating layer is arranged on the surface of the metal member. In this way, when the plastic coating layer is injection-molded on the metal member, the plastic coating layers on both sides of the metal member can be connected through the connecting columns formed in the through holes, improving the stability of the plastic coating layer coated on the metal member; when the driving member drives the flexible shaft to move and drives the skylight or the sunshade to move, the clamping groove can be used to clamp the plastic coating layer to prevent the plastic coating layer from falling off the metal member and affecting the service life of the skylight driving mechanism of the present invention. Description of the Drawings
[0007] Figure 1 is a schematic structural diagram of the skylight driving mechanism of the present invention;
[0008] Figure 2 is a schematic structural diagram of the metal member of the skylight driving mechanism of the present invention without the plastic coating layer. Detailed Embodiment
[0009] Next, in combination with Figure 1 and 2 the skylight driving mechanism of the present invention will be described in detail.
[0010] As shown in Figure 1 and 2As shown in the figure, the skylight drive mechanism of the present utility model includes a flexible shaft 1, a connecting member 2, and a driving member (not shown in the figure). The connecting member 2 is located between the flexible shaft 1 and the driving member and connects the flexible shaft 1 and the driving end of the driving member. The connecting member 2 includes a metal member 21, and the metal member 21 is connected to the flexible shaft 1 at the connecting end of the flexible shaft 1. The surface of the metal member 21 is coated with a plastic coating layer 22. In the skylight drive mechanism of the present utility model, the connecting member 2 is composed of the metal member 21 and the plastic coating layer 22 coated on the surface of the metal member 21, which can effectively increase the strength of the connecting member 2, and then increase the tensile force that the connecting member 2 can withstand, thereby reducing the probability of failure of the automobile skylight due to the tearing of the connecting member 2 in the skylight drive mechanism of the present utility model. Preferably, the flexible shaft 1 includes a core wire 11, and a winding wire 12 is wound around the core wire 11. In this way, the flexible shaft 1 is formed by combining the core wire 11 and the winding wire 12 wound around the core wire 1, which can increase the strength and durability of the flexible shaft 1, and then extend the service life of the flexible shaft 1. Preferably, the winding wire 12 is wound around the core wire 11 by roll wrapping. In this way, by using the roll wrapping method to wind the winding wire 12 around the core wire 11, the diameter of the flexible shaft 1 can be reduced on the basis of ensuring the strength and durability of the flexible shaft 1, meeting the use requirements and facilitating the flexible shaft 1 to drive the skylight and the sunshade to move to complete the opening or closing operation under the drive of the driving member. Preferably, a guiding head 13 is provided at the free end of the core wire 11 away from the connecting member 2. In this way, by providing the guiding head 13 at the free end of the core wire 11 away from the connecting member, it can guide during the movement of the flexible shaft 1 and facilitate the control of the movement path of the flexible shaft 1. Preferably, the guiding head 13 is a conical shell, and the guiding head 13 is sleeved on the free end of the core wire 11. Such a guiding head 13 has a simple structure and is convenient and fast to manufacture and install and fix.
