Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and more specifically, it relates to an electric vehicle door push rod assembly. Background Technology

[0002] Electric door push rod assemblies are mechatronic devices used to automatically open and close vehicle doors, widely used in new energy vehicles and some high-end gasoline-powered vehicles. Their core function is to convert electrical energy into linear mechanical motion, precisely controlling the opening, closing, and locking of the door to enhance vehicle intelligence and safety. Existing electric door push rod assemblies generally consist of a drive motor, a push rod body, and a mounting bracket.

[0003] Existing application number: CN202322362288.4, this utility model discloses a push rod assembly for an electric linear actuator in the field of electric linear actuator technology. It includes an electric linear actuator body, on which a push rod is mounted, and on the push rod is a rod head. Limiting devices are provided on both sides of the electric linear actuator body. Each limiting device includes a movable block slidably connected to the push rod. The movable block is provided with a first moving structure and a second moving structure. The first moving structure moves the movable block along the moving direction of the push rod, allowing an insert block to move with the push rod. The second moving structure moves the insert block in a direction perpendicular to the moving push rod, so that the insert block is inserted into the push rod after use, locking and limiting the push rod, thus supporting the push rod, preventing continuous stress on the push rod, and increasing the service life of the electric linear actuator.

[0004] Based on the above, electric door push rod assemblies lack convenient quick assembly and disassembly structures, and usually rely on multiple bolts to fix the push rod assembly to the vehicle body. During the assembly and disassembly process, not only do the bolts need to be operated one by one, which is time-consuming, but the space around the door is already small, which further increases the difficulty of bolt disassembly and hole alignment, causing many inconveniences for actual installation and subsequent maintenance. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an electric vehicle door push rod assembly. This addresses the lack of convenient and quick assembly and disassembly structures in existing electric vehicle door push rod assemblies, which typically rely on multiple bolts to fix the push rod assembly to the vehicle body. During assembly and disassembly, not only are individual bolts required, which is time-consuming, but the already limited space around the door further increases the difficulty of bolt assembly and disassembly, as well as hole alignment, leading to numerous inconveniences in actual installation and subsequent maintenance.

[0006] The purpose and function of this utility model's electric vehicle door push rod assembly are achieved through the following specific technical means: An electric vehicle door push rod assembly includes a connecting plate, a push rod body, a plug-in block, a drive motor, a plug-in box, a mounting plate, a quick-assembly assembly, and an anti-fall-off assembly. The push rod body is fixedly connected to the left side of the connecting plate; the plug-in block is fixedly connected to the rear of the push rod body; the drive motor is fixedly connected to the left side of the connecting plate; the plug-in box is plugged into the outside of the plug-in block; the mounting plate is fixedly connected to the rear plug-in box; the quick-assembly assembly is disposed inside the plug-in box; and the anti-fall-off assembly is disposed at the left end of the mounting plate.

[0007] Furthermore, the quick assembly assembly includes: a transmission knob, a transmission worm gear, and a transmission worm wheel; the transmission knob is rotatably connected to the right side of the connector box; the transmission worm gear is coaxially fixedly connected to the left end of the transmission knob; the transmission worm wheel is rotatably connected inside the connector box, and the transmission worm wheel meshes with the transmission worm gear.

[0008] Furthermore, the quick assembly assembly also includes: a transmission gear and a transmission rack; the transmission gear is coaxially and fixedly connected to the front end of the transmission worm gear; two transmission racks are provided, and the two transmission racks are slidably connected inside the plug-in box, and the two transmission racks mesh with the transmission gear respectively.

[0009] Furthermore, the quick assembly assembly also includes: a sliding positioning rod and a positioning groove; the sliding positioning rod has a "U" shaped structure, and two sliding positioning rods are provided, with the rear inner ends of the two sliding positioning rods respectively fixedly connected to the inner ends of two transmission racks; two positioning grooves are provided, with the two positioning grooves respectively provided inside the left and right sides of the insertion block, and the front inner ends of the two sliding positioning rods are respectively inserted into the two positioning grooves.

[0010] Furthermore, the anti-fall component includes: a fixing screw and an operating nut; the fixing screw is threadedly connected inside the mounting plate; the operating nut is coaxially fixedly connected to the front end of the fixing screw.

[0011] Furthermore, the anti-fall component also includes: a limiting post, a limiting bracket, and a limiting hole; the limiting post is coaxially fixedly connected to the front of the operating nut; the limiting bracket is fixedly connected to the front of the mounting plate; and the limiting hole is opened inside the front end of the limiting bracket.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, when disassembling and assembling the drive motor and push rod body, simply turn the transmission knob. Through the cooperation of the plug block and the plug box and the precise insertion of the sliding positioning rod, the push rod body can be quickly aligned with the mounting plate fixed in the vehicle body. This avoids the problem of difficult hole alignment in the narrow space of the car door, making the installation and maintenance of the drive motor and push rod body more convenient and efficient.

[0013] Secondly, by setting up an anti-fall component, when the fixing screw of the fixed mounting plate is removed, the limiting post will move with the operating nut and enter the limiting hole of the limiting bracket. When the operating nut contacts the limiting bracket, although the rear end of the fixing screw is detached from the vehicle body, it still remains in the mounting plate and is limited by the mounting plate and the limiting bracket together, so it will not fall into the gap of the vehicle body. There is no need to search for the lost bolt during installation, which further improves the smoothness of component disassembly and assembly in the narrow space of the car door.

[0014] This invention ensures efficient assembly and disassembly of the drive motor and push rod body within the vehicle body through rapid assembly components, reducing the impact of installation in the confined space of the door. Simultaneously, the anti-drop component prevents the fixing screw from falling into the gaps in the vehicle body during disassembly, making the assembly and disassembly of the drive motor, push rod body, and mounting plate more convenient and smooth, reducing additional hassles. This helps lower the operational threshold and time cost of after-sales maintenance for electric door push rod components, further enhancing the practicality of the components and the user experience.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example 1: As attached Figure 1 To be continued Figure 5As shown: This utility model provides an electric vehicle door push rod assembly, including a connecting plate 1, a push rod body 2, a plug-in block 201, a drive motor 3, a plug-in box 4, a mounting plate 5, and a quick assembly assembly; the push rod body 2 is fixedly connected to the left side of the connecting plate 1; the plug-in block 201 is fixedly connected to the rear of the push rod body 2; the drive motor 3 is fixedly connected to the left side of the connecting plate 1; the plug-in box 4 is plugged into the outside of the plug-in block 201; the mounting plate 5 is fixedly connected to the rear plug-in box 4; and the quick assembly assembly is disposed inside the plug-in box 4.

[0023] The quick-assembly components include: a transmission knob 6, a transmission worm 601, and a transmission worm wheel 7; the transmission knob 6 is rotatably connected to the right side of the plug-in box 4; the transmission worm 601 is coaxially fixedly connected to the left end of the transmission knob 6; the transmission worm wheel 7 is rotatably connected inside the plug-in box 4, and the transmission worm wheel 7 meshes with the transmission worm 601.

[0024] The quick assembly assembly also includes: a transmission gear 701 and a transmission rack 8; the transmission gear 701 is coaxially fixedly connected to the front end of the transmission worm gear 7; two transmission racks 8 are provided, and the two transmission racks 8 are slidably connected inside the plug-in box 4, and the two transmission racks 8 are respectively meshed with the transmission gear 701.

[0025] The quick assembly component also includes: a sliding positioning rod 801 and a positioning groove 202; the sliding positioning rod 801 has a "U" shaped structure, and two sliding positioning rods 801 are provided, with the rear inner ends of the two sliding positioning rods 801 respectively fixedly connected to the inner ends of the two transmission racks 8; two positioning grooves 202 are provided, and the two positioning grooves 202 are respectively provided inside the left and right sides of the plug-in block 201, with the front inner ends of the two sliding positioning rods 801 respectively inserted into the two positioning grooves 202.

[0026] The specific usage and function of this embodiment are as follows: When in use, if it is necessary to disassemble the push rod body 2 and drive motor 3 for maintenance, simply rotate the transmission knob 6. The worm gear transmission mechanism formed by the meshing of the transmission worm wheel 7 and the transmission worm 601 drives the transmission gear 701 to rotate. The transmission gear 701, through the gear and rack transmission mechanism formed by meshing with the two transmission racks 8 respectively, drives the front inner ends of the two sliding positioning rods 801 to disengage from the two positioning slots 202 respectively. Then, move the push rod body 2 and drive motor 3 forward to remove them. When it is necessary to reinstall, first insert the plug block 201 into the plug box 4, and then rotate the transmission knob 6 in the opposite direction so that the front inner ends of the two sliding positioning rods 801 are inserted back into the two positioning slots 202 respectively.

[0027] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 5As shown, it also includes an anti-fall component, which is located at the left end of the mounting plate 5.

[0028] The anti-fall component includes: a fixing screw 9 and an operating nut 901; the fixing screw 9 is threaded inside the mounting plate 5; the operating nut 901 is coaxially fixedly connected to the front end of the fixing screw 9.

[0029] The anti-fall component also includes: a limiting post 902, a limiting bracket 10, and a limiting hole 1001; the limiting post 902 is coaxially fixedly connected to the front of the operating nut 901; the limiting bracket 10 is fixedly connected to the front of the mounting plate 5; and the limiting hole 1001 is opened inside the front end of the limiting bracket 10.

[0030] The specific usage and function of this embodiment are as follows: When the connector box 4 needs to be removed from the vehicle body for maintenance, a wrench is used on the outside of the operating nut 901 and rotated to loosen the fixing screw 9 from the vehicle body. During this process, the limiting post 902 moves forward simultaneously and enters the limiting hole 1001 inside the limiting bracket 10. When the front end of the operating nut 901 moves to contact the limiting bracket 10, the rear end of the fixing screw 9 has completely detached from the vehicle body, and a portion of the rear end of the fixing screw 9 remains inside the mounting plate 5. At this time, the connector box 4 is no longer connected to the vehicle body and can be easily removed. The fixing screw 9 and the limiting post 902 are respectively restricted by the mounting plate 5 and the limiting bracket 10, thereby preventing the fixing screw 9 from detaching from the mounting plate 5 during the disassembly process and falling into the gap of the vehicle body, causing inconvenience. Multiple sets of anti-fall components can be set simultaneously as needed to facilitate the fixing of the mounting plate 5 to the vehicle body.
