[0043] The present application embodiment provides a vehicle door drive assembly, such as Figures 5 to 9 As shown, it includes a driving mechanism 1 and a flexible sleeve 3.

[0044] Specifically, combined Figure 5 , Figure 8 and Fig. 9 As shown, the driving mechanism 1 includes a mounting frame 101, a driving member 102 and a support rod 103. The driving member 102 is arranged on the mounting frame 101, and the mounting frame 101 is suitable for being installed on the vehicle door 2. The driving member 102 is connected to the support rod 103 to drive the support rod 103 to enter the opening 201 of the vehicle door 2 and extend and retract relative to the opening 201.

[0045] Specifically, Figure 5 As shown, the flexible sleeve 3 is suitable for being sleeved on the support rod 103 .

[0046] Specifically, combined Figure 5 , Figure 8 and Fig. 9 As shown, the support rod 103 has an installation state and a working state. In the installation state, the support rod 103 is inserted into the opening 201 of the vehicle door 2 through the flexible sleeve 3. In the working state, the flexible sleeve 3 is removed from the support rod 103.

[0047] The vehicle door drive assembly provided in the embodiment of the present application, when the drive mechanism 1 is installed on the vehicle door 2, the support rod 103 is first driven to extend through the driving member 102 in the installed state, so that the support rod 103 is in an extended state, and then the flexible sleeve 3 is sleeved on the outer surface of the support rod 103, and the support rod 103 passes through the flexible sleeve 3 to penetrate into the opening 201 of the vehicle door 2. In the process of the support rod 103 and the flexible sleeve 3 penetrating into the opening 201 of the vehicle door 2, the flexible sleeve 3 sleeved on the outer surface of the support rod 103 contacts the hole wall of the opening 201, and the flexible sleeve 3 plays a buffering and protective role, protecting the outer surface of the support rod 103 and preventing the outer surface of the support rod 103 from being scratched by the hole wall of the opening 201. This not only ensures the appearance integrity of the support rod 103, but also improves the smoothness of the operation of the drive mechanism 1. After installing the mounting frame 101 on the vehicle door 2 and completing the installation of the driving mechanism 1, the support rod 103 is in the working state, and the flexible sleeve 3 is removed from the support rod 103 to facilitate the subsequent installation of the driving mechanism 1 and to enable recycling, thereby reducing material waste. The entire assembly process is simple and efficient, and the installation quality and reliability of the vehicle door drive assembly are significantly improved.

[0048] Specifically, the drive mechanism 1 can select an existing door driver according to usage requirements. For example, the drive mechanism 1 can select an electric door driver, etc. In the implementation of this application, there is no specific restriction on the type of the drive mechanism 1.

[0049] Specifically, the mounting frame 101 can be detachably set on the vehicle door 2 by fasteners, can be detachably set on the vehicle door 2 by snap-fitting, and can be fixed to the vehicle door 2 by welding or the like. In the implementation of the present application, no specific restrictions are imposed on the installation method of the mounting frame 101 on the vehicle door 2.

[0050] Exemplarily, the mounting bracket 101 can be detachably mounted on the vehicle door 2 by means of bolts. When the drive mechanism 1 is installed, the bolts can play a certain pre-positioning role and facilitate subsequent maintenance and replacement.

[0051] Specifically, the driving component 102 can be an existing driving component such as an electric motor, a servo motor, a stepping motor, etc. In the embodiment of the present application, there is no specific limitation on the type of the driving component 102.

[0052] Specifically, the support rod 103 can be selected into any shape according to the requirements. For example, the axial cross-section of the support rod 103 can be set to be square, rectangular or circular, etc. In the embodiment of the present application, the shape of the support rod 103 is not specifically limited.

[0053] Specifically, the flexible sleeve 3 can be set in any shape such as a sheet or a block. When in use, the flexible sleeve 3 can be set on the support rod 103 by wrapping the outer surface of the support rod 103. The inner surface shape of the flexible sleeve 3 matches the outer surface shape of the support rod 103, that is, the flexible sleeve 3 can be set in a shape that matches the outer contour of the support rod 103. When in use, the flexible sleeve 3 can be directly set on the support rod 103, which increases the matching degree between the two. In the embodiment of the present application, the structure and shape of the flexible sleeve 3 are not specifically limited.

[0054] Specifically, Figure 5 As shown, the end of the support rod 103 can be installed with a hinge head 104. After the support rod 103 passes through the flexible sleeve 3 and enters the opening 201 of the vehicle door 2, the hinge head 104 can be installed on the vehicle body. The driving member 102 drives the support rod 103 to switch between the extended state and the retracted state, so as to realize the switching of the vehicle door 2 between the open state and the closed state.

[0055] In some embodiments of the present application, Figures 5 to 7 As shown, the flexible sleeve 3 is provided with an axial through hole 301 , and a side wall of the flexible sleeve 3 is provided with an opening 302 , which is communicated with the axial through hole 301 and penetrates along the length direction of the flexible sleeve 3 .

[0056] By providing the axial through hole 301 and the opening 302 communicating with the axial through hole 301 on the flexible sleeve 3, when the flexible sleeve 3 is sleeved on the strut 103, it is only necessary to pass the opening 302 of the flexible sleeve 3 through the outer surface of the strut 103 so that the strut 103 is located in the axial through hole 301, and the flexible sleeve 3 can be easily sleeved on the strut 103. When removing the flexible sleeve 3, a force in a direction away from the strut 103 is applied to the flexible sleeve 3, so that the flexible sleeve 3 is directly separated from the strut 103 from the opening 302, so as to facilitate the assembly or disassembly of the flexible sleeve 3. At the same time, since the flexible sleeve 3 has a certain flexibility, it is convenient to use on struts 103 with different diameters or shapes, thereby improving the versatility and adaptability of the flexible sleeve 3.

[0057] Specifically, the axial cross-section of the axial through hole 301 can be set to be square, circular, elliptical, etc. In the embodiment of the present application, the shape of the axial cross-section of the axial through hole 301 is not specifically limited.

[0058] In some embodiments of the present application, Figure 6 and Figure 7 As shown, the width of the opening 302 of the flexible sleeve 3 gradually increases from the inside to the outside.

[0059] The gradual increase in the width of the opening 302 provides a progressive guide for the support rod 103, making it easier and smoother for the support rod 103 to pass through the opening 302 of the flexible sleeve 3 and enter the axial through hole 301, effectively reducing the resistance during the installation process. Once the support rod 103 is completely passed through and located in the axial through hole 301, the narrow width of the opening 302 inside the flexible sleeve 3 can fit the support rod 103 tightly, thereby preventing the support rod 103 from accidentally falling out of the opening 302, ensuring the stability and safety of the installation.

[0060] It should be noted that the “from inside to outside” mentioned above can be understood as the direction from the inner surface of the flexible sleeve 3 to the outer surface of the flexible sleeve 3 .

[0061] Specifically, the axial cross section of the opening 302 may be set to be in the shape of an isosceles trapezoid. In the embodiment of the present application, the shape of the opening 302 is not specifically limited.

[0062] In some embodiments of the present application, Figure 6 As shown, the width of the opening 302 is smaller than the width of the support bar 103 .

[0063] Since the width of the opening 302 is smaller than the width of the support rod 103, a tight fit between the flexible sleeve 3 and the support rod 103 can be ensured, effectively preventing the flexible sleeve 3 from sliding on the support rod 103, and effectively preventing the flexible sleeve 3 from accidentally falling off the support rod 103, thereby improving the stability of the flexible sleeve 3 and the support rod 103 after fitting.

[0064] Exemplarily, when the width of the support rod 103 is about 10 mm, the width of the opening 302 can be set to about 6 mm to prevent the flexible sleeve 3 from accidentally falling off the support rod 103 .

[0065] In some embodiments of the present application, Figure 6 As shown, the diameter of the axial through hole 301 is smaller than or equal to the diameter or diagonal length of the axial cross section of the support rod 103 .

[0066] The smaller axial through hole 301 aperture closely matches the axial cross-section of the support rod 103, which can provide better fixation and support, so that the flexible sleeve 3 can be stably and firmly mounted on the outer surface of the support rod 103, and avoid the flexible sleeve 3 from sliding on the support rod 103 due to interference with the inner wall of the opening 201 when the flexible sleeve 3 passes through the opening 201.

[0067] Exemplarily, when the axial cross section of the support rod 103 is circular, the diameter of the axial through hole 301 is less than or equal to the diameter of the axial cross section of the support rod 103. When the axial cross section of the support rod 103 is square or rectangular, the diameter of the axial through hole 301 is less than or equal to the diagonal length of the axial cross section of the support rod 103.

[0068] In some embodiments of the present application, Figure 5 As shown, the length of the flexible sleeve 3 is smaller than the length of the support rod 103 in the extended state.

[0069] When assembling the flexible sleeve 3, since the flexible sleeve 3 is shorter than the extended support rod 103, the assembly of the flexible sleeve 3 is easier, and the flexible sleeve 3 only needs to cover the key parts of the support rod 103, such as the part in contact with the opening 201 of the door 2, without covering the entire support rod 103, thereby reducing the complexity of the assembly process and improving work efficiency. Similarly, when the flexible sleeve 3 needs to be disassembled, the shorter length also makes the disassembly process more convenient.

[0070] In some embodiments of the present application, the thickness of the flexible sleeve 3 is 1.5 mm-3 mm.

[0071] The thickness range of 1.5 mm to 3 mm allows the flexible sleeve 3 to maintain a certain degree of flexibility, which is convenient for installation and removal, and can also adapt to different diameters of the support rods 103. Within this thickness range, the flexible sleeve 3 can provide sufficient strength and durability to withstand the wear and pressure in daily use, and provide good protection for the support rod 103 to prevent the support rod 103 from being damaged during the process of passing through the opening 201.

[0072] In some embodiments of the present application, the flexible sleeve 3 is one of a rubber sleeve, a silicone sleeve or a sponge sleeve.

[0073] The flexible sleeve 3 made of these materials has good elasticity, can be easily put on the support rod 103, and can be restored to its original state when removed. At the same time, it can provide good physical protection for the support rod 103 to prevent the outer surface of the support rod 103 from being scratched.

[0074] In the embodiment of the present application, the material of the flexible sleeve 3 is not specifically limited.

[0075] In some embodiments of the present application, Figure 5 As shown, at least one positioning bolt 1011 is also provided on the mounting frame 101 , and the positioning bolt 1011 is suitable for being installed on a corresponding assembly hole of the inner plate of the vehicle door 2 .

[0076] When installing the driving mechanism 1, the positioning bolts 1011 on the mounting frame 101 can be pre-hung on the corresponding assembly holes of the inner plate of the vehicle door 2 to prevent the support rods 103 on the driving mechanism 1 from interfering with the hole wall of the opening 201 and causing scratches due to the driving mechanism 1 falling down. At the same time, the positioning bolts 1011 directly cooperate with the assembly holes of the inner plate of the vehicle door 2, which simplifies the installation process of the driving mechanism 1 and improves the assembly efficiency.

[0077] Specifically, the positioning bolt 1011 can be an existing bolt such as a T-bolt, a hexagonal bolt, etc. In the embodiment of the present application, there is no specific limitation on the type of the positioning bolt 1011.

[0078] Specifically, the positioning bolts 1011 can be installed at both ends of the mounting frame 101 to ensure that the mounting frame 101 can be firmly fixed on the inner plate of the vehicle door 2. In the embodiment of the present application, the installation position and number of the positioning bolts 1011 are not specifically limited.

[0079] For example, Figure 5 As shown, a positioning bolt 1011 is provided at one end of the mounting frame 101 , and two positioning bolts 1011 arranged in parallel are provided at the other end.

[0080] The installation process of the door drive assembly in this embodiment is described as follows:

[0081] The driving member 102 drives the support rod 103 to extend, so that the support rod 103 enters the extended state, so that the support rod 103 can smoothly pass through the opening 201 of the door 2. The flexible sleeve 3 is sleeved on the outer surface of the support rod 103 through the opening 302 to provide protection when the support rod 103 passes through the opening 201 of the door 2.

[0082] The support rod 103 together with the flexible sleeve 3 mounted thereon are inserted into the opening 201 of the vehicle door 2. During this process, the flexible sleeve 3 contacts the hole wall of the opening 201. Due to the protective effect of the flexible sleeve 3, the outer surface of the support rod 103 will not directly rub against the hole wall, thereby avoiding possible scratches.

[0083] After the support rod 103 and the flexible sleeve 3 are successfully inserted into the opening 201 , the mounting frame 101 of the driving mechanism 1 is fixed to the vehicle door 2 by means of the positioning bolts 1011 .

[0084] After the installation of the drive mechanism 1 is completed, the flexible sleeve 3 is removed from the support rod 103 so that it can be reused when the next drive mechanism 1 is installed.

[0085] On this basis, refer to Figures 5 to 9 As shown, the embodiment of the present application also provides a vehicle installation device, such as Figures 5 to 9 As shown, it includes a vehicle door 2 and a vehicle door drive assembly.

[0086] Specifically, Fig. 9 As shown, an opening 201 is provided on the vehicle door 2 .

[0087] Specifically, the mounting bracket 101 is mounted on the vehicle door 2 , and the support rod 103 passes through the flexible sleeve 3 and penetrates into the opening 201 .

[0088] In the vehicle installation device provided by the embodiment of the present application, when the support rod 103 and the flexible sleeve 3 are inserted into the opening 201 of the vehicle door 2, the flexible sleeve 3 sleeved on the outer surface of the support rod 103 contacts the hole wall of the opening 201, and the flexible sleeve 3 plays a buffering and protective role, protecting the outer surface of the support rod 103 and preventing the outer surface of the support rod 103 from being scratched by the hole wall of the opening 201. After the installation of the driving mechanism 1 is completed, the flexible sleeve 3 is removed from the support rod 103, so that it can be recycled when the driving mechanism 1 is installed later, reducing material waste.

[0089] It should be noted that the vehicle in this application may refer to a large car, a small car, a special-purpose car, etc. For example, according to the car model, the car in this application may be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV) or other models. Generally, a vehicle is provided with wheels, a power source, and a transmission system arranged between the wheels and the power source. The transmission system can transmit the power provided by the power source to the wheels, so that the wheels rotate, thereby driving the vehicle to travel.

[0090] It should be noted that in the embodiments of the present application, the type of the power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.
