Description

Technical Field

[0001] The utility model relates to the technical field of automobile modification, in particular to an automobile electric curtain driving structure. Background Art

[0002] The windows are located on the left and right sides of the car. People can adjust the air flow in the car by changing its height to improve the air quality in the car. It can also bring cool air into the stuffy car, which is conducive to creating a healthy and pleasant driving and riding experience. However, the windows cannot effectively block the hot sun, which not only brings discomfort to people in high temperatures, but also represents the damage of ultraviolet radiation to human skin. In addition, in the passenger area of ​​the commercial vehicle modification, curtains are also needed for privacy and other reasons.

[0003] At present, there are also electric curtains in the field of modified cars, but the structure is not perfect. Usually, it is a simple steel wire rope driven by a motor to drive the curtain to open and close, which lacks flexibility and stability. In addition, the steel wire rope may cause sliding stagnation due to oxidation and other reasons, which affects the automatic opening and closing of the curtain and the user experience is not good. At the same time, since the electric curtain is fixed to the moving mechanism, it is not convenient for personnel to manually adjust it. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and Figure 2 As shown, the utility model provides a technical solution: an automobile electric curtain driving structure, comprising a shell 1, a driving motor 2 is installed at one end of the shell 1, a lead screw 5 is rotatably connected to the inner cavity of the shell 1 along the length direction, the driving motor 2 and the lead screw 5 are connected through a transmission assembly 3, a nut slider 6 is threadedly connected to the lead screw 5, a guide column 7 is arranged in the inner cavity of the shell 1, the guide column 7 penetrates the nut slider 6 and is slidably connected to the nut slider 6; a plurality of belt rings 9 are slidably sleeved on the guide column 7, and a curtain 10 is fixedly connected to the lower part of the belt ring 9; a first magnet ring 8 is fixedly connected to the guide column 7, a second magnet ring is arranged on one side of the nut slider 6, and the first magnet ring 8 and the second magnet ring can be magnetically connected to the belt ring 9; a notch 11 matching the curtain 10 is opened at the lower part of the shell 1.

[0023] The utility model, through the provided driving motor 2, transmission assembly 3 and lead screw 5, can be driven by the driving motor 2, so that the nut slider 6 can drive the curtain 10 to move along the guide column 7, thereby realizing the electric opening and closing of the curtain 10; through the provided first magnetic ring 8, second magnetic ring 12 and belt ring 9, it is convenient for personnel to manually separate the magnetic fixation between the belt ring 9 and the magnetic ring in daily life, so that personnel can manually pull the curtain 10 to make the belt ring 9 slide on the guide column 7, thereby completing the switching between the electric adjustment mode of the curtain 10 and the manual adjustment mode of the curtain 10, and when it is necessary to adjust to electric adjustment, the belt ring 9 and the second magnetic ring 12 can be magnetically fixed together again, at this time, the driving motor 2 is started, and the nut slider 6 realizes the adjustment of the curtain 10 through the belt ring 9.

[0024] Reference Figure 4As shown, in this embodiment, the transmission component 3 includes a worm fixedly connected to the output end of the drive motor 2, and a worm wheel matching the worm is fixedly provided on the lead screw 5. In this solution, by adopting a worm gear as the transmission component 3, the space of the inner cavity of the housing 1 can be effectively utilized, the layout of the worm gear is reasonably selected, and the layout of the lead screw 5 can be adapted; at the same time, a worm gear with a self-locking condition can be used for transmission, so that the lead screw 5 can self-lock in the process of driving the nut slider 6 to move, effectively ensuring the stability of the transmission during the adjustment of the curtain 10. In actual application, the transmission component 3 can adopt a bevel gear fixedly connected to the output end of the drive motor 2, and a bevel gear is also fixedly provided on the lead screw 5, and the two bevel gears are connected in transmission. Therefore, personnel can choose a bevel gear as a transmission solution based on the cost investment.

[0025] Reference Figure 4 As shown, in this embodiment, a support plate 4 is fixedly provided in the inner cavity of the housing 1, and the lead screw 5 passes through the support plate 4 and is rotatably connected to the support plate 4. In this solution, the support plate 4 can cooperate with the housing 1 to provide stable support for the lead screw 5, so as to avoid excessive concentration of stress at the center of gravity of the lead screw 5 during operation, thereby causing the middle part of the lead screw 5 to be easily bent, thereby reducing the stability of the transmission between the nut slider 6 and the lead screw 5.

[0026] Reference Figure 2 and 3 As shown, in this embodiment, the two belt rings 9 magnetically fixed to the magnet ring cannot be separated from the first magnet ring 8 and the second magnet ring 12 during the up and down shaking of the shell 1. When the curtain 10 driving structure corresponding to this scheme is installed on the vehicle body, since the vehicle body is often in a driving state, the shell 1 shakes up and down, which causes the guide column to be tilted. At this time, due to the effect of gravity, the belt ring 9 will slide on the guide column 7. At this time, the belt ring 9 magnetically fixed to the magnet ring will be intermittently pulled. At this time, it is necessary to ensure that the belt ring 9 cannot be separated from the magnet ring to ensure the operability of the subsequent electric adjustment of the curtain 10. Otherwise, personnel are required to manually fix the belt ring 9 to the magnet ring by magnetic attraction again.

[0027] In this embodiment, an arc-shaped opening matching the first magnet ring 8 is provided on the guide column 7, the first magnet ring 8 is snap-fitted and fixed in the opening, and the second magnet ring 12 is magnetically fixed to one side of the nut slider 6. In this solution, by snap-fitting the first magnet ring 8 with the opening and magnetically fixing the second magnet ring 12, the process of installing and fixing the magnet rings in the entire electric drive structure can be simplified, and the actual molding cost of the entire electric curtain 10 drive structure can also be saved.
