TECHNICAL FIELD

[0001] The utility model relates to a kind of automobile accessories, in particular to a double-track lifter mounting plate assembly. BACKGROUND

[0002] In the field of automobile manufacturing, double-track lifter mounting plate assembly is usually used for the lifting operation of vehicle door glass. It fixes and supports the glass lifter through the specific structure on the mounting plate, ensuring the glass can move up and down along the guide rail smoothly. Specifically, in the use process, the driving mechanism of the lifter is connected with the internal structure of the door through the mounting plate, and the glass edge is embedded in the guide groove, so as to realize accurate lifting action. This design is widely used in passenger cars and commercial vehicles, providing convenient window control function for vehicles, while also putting forward higher requirements for the strength and precision of the mounting plate.

[0003] Chinese patent document CN219650978U discloses a glass lifter mounting plate, which includes a base body provided with a transverse mounting groove. The base body is provided with a support seat on the side of the transverse mounting groove for mounting the glass lifter. The base body is provided with a positioning frame at the edge position. The positioning frame is provided with a guide groove for sliding cooperation with the edge of the lifting glass along the height direction of the base body. The mounting plate is made of high-strength plastic material.

[0004] Although the glass lifter mounting plate in the prior art adopts high-strength plastic material to reduce weight and cost, its overall strength still cannot compare with that of metal material. In actual use, when the vehicle encounters collision or external impact, the plastic material mounting plate is easy to deform or even break, resulting in damage to the function of the lifter, and further affecting the normal use of the window. In addition, the integral plastic mounting plate needs to be replaced as a whole after being damaged, resulting in high repair cost. SUMMARY

[0005] In view of the deficiencies of the prior art, the utility model provides a double-track lifter mounting plate assembly with higher structural strength and lower repair cost.

[0006] The utility model discloses the following technical scheme in order to realize above-mentioned purpose: a double track lifter mounting plate assembly, including mounting plate and lifter, the lifter includes two slide rails that are arranged in parallel on the mounting plate, the clamping plate for clamping glass is slidably arranged on each slide rail, and the drive rope is driven by the rotating motor, the both ends of each slide rail are provided with the pulley for preventing the drive rope from falling out, the drive rope is fixed on the rotating motor and is driven by the rotating motor to move after being successively from the pulley of both ends of two slide rails, the mounting plate includes the metal sheet and the plastic plate, the corresponding end face of metal sheet and plastic plate is provided with the first assembly part and the second assembly part that can be mutually stacked respectively, a plurality of first fixed holes are arranged on the first assembly part and the second assembly part, and the first fixed hole of the first assembly part and the second assembly part is overlapped after being stacked and is correspondingly provided with the fastener of first fixed hole number to form the fixed between metal sheet and plastic plate.

[0007] The utility model discloses the following technical scheme in order to realize above-mentioned purpose: a double track lifter mounting plate assembly, including mounting plate and lifter, the lifter includes two slide rails that are arranged in parallel on the mounting plate, the clamping plate for clamping glass is slidably arranged on each slide rail, and the drive rope is driven by the rotating motor, the both ends of each slide rail are provided with the pulley for preventing the drive rope from falling out, the drive rope is fixed on the rotating motor and is driven by the rotating motor to move after being successively from the pulley of both ends of two slide rails, the mounting plate includes the metal sheet and the plastic plate, the corresponding end face of metal sheet and plastic plate is provided with the first assembly part and the second assembly part that can be mutually stacked respectively, a plurality of first fixed holes are arranged on the first assembly part and the second assembly part, and the first fixed hole of the first assembly part and the second assembly part is overlapped after being stacked and is correspondingly provided with the fastener of first fixed hole number to form the fixed between metal sheet and plastic plate.

[0008] Further, at least two fixed grooves are arranged on each slide rail, and at least one fixed groove is arranged in the part corresponding to the metal sheet and the plastic plate, a second fixed hole that can be spliced is arranged on the position corresponding to the metal sheet or the plastic plate of each fixed groove, and the slide rail is fixed between the metal sheet and the plastic plate by arranging the fastener in the second fixed hole.

[0009] By arranging the fixed groove on the slide rail and cooperating with the second fixed hole on the metal sheet and the plastic plate, the slide rail can be reliably fixed, and the connection stability between the metal sheet and the plastic plate can be enhanced, so that the anti-deformation ability of the overall structure is improved. This design fully utilizes the geometric shape of the slide rail, and realizes multi-position connection reinforcement without adding additional parts. As a preferred mode, reinforcing ribs can be added to the bottom of the fixed groove to further improve the carrying capacity and bending resistance of the slide rail. At the same time, by arranging the second fixed hole on the metal sheet and the plastic plate respectively, the stress can be dispersed, and damage caused by stress concentration at a single connection point can be avoided, thereby prolonging the service life of the device.

[0010] Further, the driving motor is arranged on the plastic plate, the driving motor comprises a wire wheel fixed with the driving rope, the plastic plate is provided with a through hole only for the wire wheel to pass through, and the two sides of the plastic plate are respectively provided with mounting covers fixed through fasteners, and the two mounting covers are matched to fix the driving motor.

[0011] Arranging the driving motor on the plastic plate and fixing the driving motor through the mounting cover not only avoids the influence of drilling holes on the metal plate on the overall strength, but also reduces the strength loss of the plastic plate through smaller drilling sizes, thereby improving the reliability of the overall structure. The design of the mounting cover can also protect the driving motor from external environmental interference, such as dust or water vapor intrusion, and facilitate disassembly and replacement of the motor. As a preferred mode, an elastic sealing gasket can be arranged on the inner side of the mounting cover to further enhance the waterproof and dustproof effect. In addition, the mounting cover is fixed through fasteners, which is simple to operate, can quickly complete assembly, and reduces the complexity and time cost in the production process.

[0013] Through the interference fit between the sliding plate and the sliding groove, instead of the traditional fastener fixing mode, the loosening phenomenon of the clamping plate during long-time operation can be effectively prevented, thereby improving the stability and service life of the clamping plate. The design of the interference fit simplifies the assembly process, reduces the number of parts, and reduces the manufacturing cost. As a preferred mode, the surface of the sliding plate can be roughened (such as sandblasting or knurling) to further enhance the friction between the sliding plate and the sliding groove and ensure more stable connection effect. In addition, the interference fit can also reduce the influence of external vibration on the position of the clamping plate, making the clamping action more stable and reliable.

[0014] Further, the two parts intersecting in the L-shaped sliding groove are each provided with a plurality of expansion ribs, and the plurality of expansion ribs are matched to form an interference fit between the sliding groove and the sliding plate.

[0015] The addition of expansion ribs in the sliding groove can significantly improve the connection stability of the interference fit between the sliding groove and the sliding plate, and can maintain good clamping effect even in high-frequency reciprocating motion. The design of the expansion rib enhances the firmness of the connection through the pre-tightening force generated by local deformation, while avoiding the loosening problem that may occur with traditional fasteners. As a preferred way, the number and distribution density of the expansion ribs can be adjusted according to actual needs to adapt to different load conditions and working environments. For example, in situations requiring higher stability, the number of expansion ribs can be increased and their arrangement angle can be optimized to further enhance the shear resistance. In addition, the presence of the expansion rib can also compensate for wear caused by long-term use, extending the service life of the clamping plate. BRIEF DESCRIPTION OF DRAWINGS

A plurality of first fixing holes 13 are arranged on the first assembling part 111 and the second assembling part 121, and these fixing holes will overlap after stacking, and the metal plate 11 and the plastic plate 12 are fixed together through fasteners. This assembling method not only facilitates maintenance, but also improves the overall strength by using the metal part.

[0021] The lifter comprises two sliding rails 2, which are arranged in parallel on the mounting plate. A clamping plate 3 is slidably mounted on each sliding rail 2 for clamping glass. In order to ensure the stable fixation of the sliding rail 2, at least two fixing grooves 21 are arranged on each sliding rail 2, at least one of which corresponds to the metal plate 11 or the plastic plate 12. A second fixing hole 211 is arranged in the fixing groove 21, and the sliding rail 2 is fixedly connected with the metal plate 11 and the plastic plate 12 by means of fasteners inserted in the second fixing hole 211, which not only fixes the sliding rail 2, but also further enhances the connection stability between the metal plate 11 and the plastic plate 12.

[0022] The lifting device further comprises a driving rope 4 and a rotating motor 5. The driving rope 4 is fixed on the rotating motor 5 after passing through the pulleys 22 at both ends of the slide rail 2 in sequence, and is driven to move by the rotating motor 5. The rotating motor 5 is arranged on the plastic plate 12 instead of the metal plate 11, so as to avoid drilling holes on the metal plate 11 and reduce the overall strength of the metal plate 11. The rotating motor 5 comprises a wire reel 51 fixed with the driving rope 4. The plastic plate 12 is provided with a through hole 122 only for the wire reel 51 to pass through, and two mounting covers 123 are arranged on both sides of the plastic plate 12, respectively.

[0023] An L-shaped sliding plate 23 is arranged on one side of the slide rail 2, and the clamping plate 3 is designed with a sliding groove 31 corresponding to the shape of the sliding plate 23, which can be inserted into the sliding plate 23 and form an interference fit. This design can avoid the problem of loosening of the fasteners after long-term use. In order to further improve the stability of the interference fit between the sliding groove 31 and the sliding plate 23, the two parts intersecting in the sliding groove 31 are provided with a plurality of expansion ribs 311, which cooperate to make the connection between the sliding groove 31 and the sliding plate 23 more firm.

[0024] The working principle of the embodiment is as follows: when the rotating motor 5 is started, it drives the clamping plate 3 on the slide rail 2 to slide along the slide rail 2 through the driving rope 4. The clamping plate 3 is kept stable by the interference fit between the sliding groove 31 and the sliding plate 23, and will not loosen after long-term use. At the same time, the slide rail 2 is fixed with the metal plate 11 and the plastic plate 12 through the fixing groove 21, which enhances the stability of the overall structure. The rotating motor 5 is arranged on the plastic plate 12 and fixed by the mounting cover 123, which not only protects the overall strength of the metal plate 11, but also ensures the structural stability of the plastic plate 12. The whole device is designed reasonably, and it is convenient to maintain and replace parts. As for how the rotating motor 5 drives the clamping plate 3 to slide along the slide rail 2 through the driving rope 4, it belongs to the prior art, and will not be described in detail here.

[0025] The above embodiment is only one of the preferred specific embodiments of the present application, and the usual changes and replacements made by those skilled in the art within the technical scheme of the present application are all included in the protection scope of the present application.
