Description

Technical Field

[0001] The utility model relates to the technical field of slide rail motor installation, in particular to an in-vehicle slide rail mechanism assembly. Background Art

[0002] When the slide rail motor interferes with the vehicle body, the motor needs to be installed in a raised form. In some projects, in order to adapt to the customer's vehicle body design, the slide rail needs to be arranged in the form of high and low rails.

[0003] At present, the body design of some car models requires the seats to have an ultra-low block value to adapt to it. This requirement can be met by lifting the motor or arranging the high and low rails. The existing transmission solution is to tilt the gearbox and directly set a flexible shaft between the height rail and the motor. The flexible shaft is bent to achieve a small distance lifting installation of the motor, but the lifting height is relatively limited and cannot meet the needs of the current project. In addition, due to the lifting installation of the motor, the connection end of the flexible shaft and the motor and the connection end of the gearbox rotate out of center, causing the flexible shaft to jump during rotation and hit the bracket and the connecting square hole, resulting in abnormal noise.

During use, it can be arranged according to the actual layout in the vehicle, so that the battery assembly or ECU or ventilation and heating module can be stored in the functional space to save space in the vehicle and improve utilization rate. The drive motor 4 and the first slide rail 71 are connected by a transmission mechanism; the transmission mechanism includes a first flexible shaft 11 connected to the first slide rail 71, a universal joint 2 arranged at one end of the first flexible shaft 11 away from the first slide rail 71, a rigid shaft 31 arranged at the universal joint 2, and a second flexible shaft 12 connected between the rigid shaft 31 and the drive motor 4, a universal joint is arranged between the rigid shaft and the universal joint, and the rigid shaft is arranged tilted.

[0042] In the present invention, a preferred embodiment is: the connection structure between the first slide rail 71 and the drive motor 4 is: the first slide rail 71-first flexible shaft 11-universal joint 2-rigid shaft 31-universal joint 2-second flexible shaft 12-drive motor 4, the power of the drive motor 4 is output through the second flexible shaft 12, and the transmission direction is changed through the universal joint 2, through the rigid shaft 31, and the transmission direction is changed again through the universal joint 2, and the power is transmitted to the first slide rail 71 through the first flexible shaft 11. By using the universal joint 2 to change the transmission direction of the power of the drive motor 4, the connection between the drive motor 4 and the first slide rail 71 is realized, so that the drive motor provides a sliding function for the first slide rail. Preferably, the drive motor 4 can be fixedly installed on a battery assembly arranged on the vehicle chassis, thereby saving installation space, and the universal joint 2 is a cross universal joint 2 or a ball head universal joint 2.

[0043] Furthermore, the setting height of the first flexible shaft 11 is higher than the setting height of the second flexible shaft 12, or the setting height of the second flexible shaft 12 is lower than the setting height of the first flexible shaft 11, so that there is a height difference between the drive motor 4 and the first slide rail 11, thereby allowing the drive motor 4 to have a higher degree of freedom to be set in the internal space of the vehicle body.

[0044] See also Figure 2 , Figure 3 , Fig.14 and Fig.15 Furthermore, in the vehicle, a second slide rail 72 is provided on the side of the drive motor 4 away from the first slide rail 71, and the second slide rail 72 is parallel to the first slide rail 71.

Preferably, a sleeve 91 is also sleeved outside the third flexible shaft 13 to protect the third flexible shaft. The third flexible shaft 13 can also be replaced with a rigid shaft. Compared with directly connecting the motor and the slide rail by a flexible shaft in the prior art, in the present utility model, by connecting the flexible shaft and the rigid shaft through a universal joint 2, the driving motor 4 can be lifted or lowered by a large distance. For example Figure 4 the vertical distance D1 formed between the driving motor 4 and the first slide rail 71 in Fig.15 the vertical distance D2 formed between the driving motor 4 and the first slide rail 71 in Fig.17 and the vertical distance D3 formed between the driving motor 4 and the first slide rail 71 in

[0046] . Further, gear boxes 81 are respectively arranged on the first slide rail 71 and the second slide rail 72. The second slide rail 72 being flush with the driving motor 4 means that the input hole 811 of the gear box 81 on the second slide rail 72 is flush with the output hole 41 of the driving motor 4.

[0047] . Further, the driving motor 4 is arranged to be centered relative to the first slide rail 71 and the second slide rail 72; or closer to the first slide rail 71; or closer to the second slide rail 72. Preferably, different installation positions of the second slide rail 72, the first slide rail 71, and the driving motor 4 form different-sized functional spaces. Refer to Fig.10 and Fig.13 the functional spaces V1 and V2 in which change with the change of the distances L1 and L2 between the driving motor 4 and the first slide rail 71. For example, L1 > L2, so V1 < V2, thereby adapting to the vehicle interior space in various different situations, making the layout of the vehicle interior space more flexible. At this time, the second slide rail 72 can be flush with the driving motor 4, or there can be a height difference between the second slide rail 72 and the driving motor 4.

[0048] Refer to Figure 7 and Figure 8 . Further, the vehicle interior slide rail mechanism assembly further includes a motor bracket 6. The driving motor 4 is installed on the motor bracket 6, and the motor bracket 6 is fixedly connected to the first slide rail 71 and the second slide rail 72 respectively. Preferably, the motor bracket 6 can be installed between the first slide rail 71 and the second slide rail 72 by means of bolts 5, pins, buckles, etc. A motor installation groove is formed on the motor bracket 6, and the driving motor 4 is installed in the motor installation groove.

[0049] Further, the motor bracket 6 is provided with a plurality of grooves to support and limit at least one of the first flexible shaft 11, the second flexible shaft 12 and the rigid shaft 31. Preferably, the motor bracket 6 is provided with a semicircular groove 101 and a V-shaped groove 102, the flexible shaft is clamped in the semicircular groove 101, the first flexible shaft 11, the second flexible shaft 12 and the third flexible shaft 13 are limited and supported by the semicircular groove 101 and the V-shaped groove 102, so as to avoid the first flexible shaft 11, the second flexible shaft 12 and the third flexible shaft 13 from jumping when transmitting the power of the drive motor 4, and the rigid shaft 31 is limited and supported by the V-shaped groove 102.
