Description

Technical Field

[0001] The utility model relates to the technical field of vehicle parts, and more specifically, to a driving mechanism for the downward and sideward opening of a pickup tailgate. Background Art

[0002] In the current field of automotive design, pickup trucks are widely popular due to their versatility and practicality, especially in scenarios where a large amount of cargo needs to be carried or heavy objects need to be towed. However, the traditional tailgate control mechanism of pickup trucks has certain limitations in design. Most pickup trucks are equipped with a tailgate that can only be flipped downward. Although this meets the daily use requirements to a certain extent, in specific situations, such as loading and unloading operations in narrow spaces, or when items need to be quickly taken and placed from the side, this single opening method is not flexible enough.

[0003] To solve this problem, there are also some tailgate designs on the market that can be opened laterally, but these designs often rely on manual operation, or even with electric assistance, they cannot seamlessly switch between the two modes of downward and sideward opening. Such a design not only increases the operation complexity of the driver and reduces efficiency, but also runs counter to the trend of lightweight, electrification, and intelligence pursued by modern automobiles.

[0049] The downward-flipping tailgate refers to that the tailgate can be rotated downward to open relative to the vehicle body; the side-flipping tailgate refers to that the tailgate can be rotated to open relative to the vehicle body along one of its side ends; these two opening methods can enable the tailgate to be used in different scenarios and have higher flexibility. In view of the fact that the existing pickup truck tailgates cannot achieve these two opening methods simultaneously, the present application provides a multi-mode drive mechanism for application to pickup trucks.

[0050] This drive mechanism can fully electrically realize the functions of downward flipping and side flipping of the tailgate. They can automatically adjust the position of the tailgate according to the driver's instructions, and can easily achieve either downward flipping for convenient loading and unloading of goods or lateral opening to meet the requirements of special scenarios.

[0051] The drive mechanism of the present application will be described in detail through the following embodiments.

[0052] Embodiment 1:

[0053] As Figures 1 - 5 shown, in this embodiment, a drive mechanism for downward flipping and side flipping of a pickup truck tailgate is provided. The vehicle includes: a vehicle body (not shown in the figure) and a tailgate 1; the drive mechanism can open or close the tailgate 1 in multiple modes according to actual needs.

[0054] Specifically, the drive mechanism includes: a mounting bracket 100, which is mounted on the tailgate 1 by bolts; a drive shaft 200, which is horizontally arranged on the mounting bracket 100; a hinge assembly 300, whose rotation axis is vertically arranged and is used to hinge one end of the drive shaft 200 to one side of the vehicle body tail; a latch assembly 400, which is used to lock the other end of the drive shaft 200 to the other side of the vehicle body tail or unlock it from the other side of the vehicle body tail; a drive assembly 500, which is arranged on the mounting bracket 100 and is used to apply a rotational torque to the drive shaft 200, so that the tailgate 1 and the drive assembly 500 rotate relative to the drive shaft 200 to open or close the tailgate 1 from the vehicle body; and / or, drive the tailgate 1 to rotate along the rotation axis of the hinge assembly 300 to open or close the tailgate 1 from the vehicle body; an auxiliary drive assembly 600, which provides an auxiliary thrust or pull for the tailgate 1 when the tailgate rotates to open or close relative to the drive shaft 200;

[0055] Wherein, by adjusting the latch assembly 400 to the locked state or the unlocked state, the two opening modes of the tailgate 1 are switched.

[0056] In this embodiment, the core components capable of realizing the lower flip and side flip of the tailgate are the horizontally arranged drive shaft 200, drive assembly 500, hinge assembly 300 and latch assembly 400.

[0057] When the tailgate is opened by lower flipping, first lock the latch assembly 400 so that the end of the drive shaft 200 away from the hinge assembly 300 is fixed on the vehicle body. At this time, both ends of the drive shaft 200 are fixed on the vehicle body. By controlling the drive assembly 500 to start, a rotational torque can be applied to the drive shaft 200. However, since both ends of the drive shaft 200 are fixed and cannot rotate, the entire drive assembly 500 will rotate relative to it. While the drive assembly 500 rotates, it drives the mounting bracket 100 and the tailgate to rotate, realizing the lower swing opening;

[0058] When the tailgate is opened by side flipping, first unlock the latch assembly 400 so that the end of the drive shaft 200 away from the hinge assembly 300 is in an active state. At this time, the drive shaft 200 can swing relative to the vehicle body through the hinge. Since the drive shaft 200 is restricted on the mounting bracket 100 and the drive shaft 200 is connected to the drive assembly 500, when the drive shaft 200 swings, it can drive the drive assembly 500, mounting bracket 100 and tailgate to swing synchronously, realizing the side swing opening.

[0059] For the drive mechanism that realizes the above two drive modes of the tailgate, each of its structures is a relatively common structure when taken out separately. However, after combining each structure, it can subvert the single-mode drive tailgate drive mechanism of the transmission, with strong practicability and broad application prospects.

[0060] In this embodiment, specifically, the hinge assembly 300 includes: a fixed plate 310 fixedly arranged on the vehicle body; a movable plate 320; and a connecting shaft 330 for rotatably connecting the fixed plate 310 and the movable plate 320.

[0061] Wherein, the movable plate 320 is fixedly connected to one end of the drive shaft 200.

[0062] The latch assembly 400 includes: a fixed lock base 410 arranged on the vehicle body, which has a lock groove 411; a movable lock base 420 arranged on the tailgate and connected to the end of the drive shaft 200 far from the hinge assembly 300, and the movable lock base 420 has a lock pin 421 that can be horizontally inserted into the lock groove 411; and a lock tongue 430 arranged on the fixed lock base 410, which can rotate relative to the fixed lock base 410 between a locking position and an unlocking position to restrict the lock pin 421 from disengaging from the lock groove 411 or to release the restriction.

[0063] The structures of the above-mentioned hinge assembly 300 and latch assembly 400 are relatively common, as long as their respective functions can be realized, so no detailed description will be made here.

[0064] The drive assembly 500 includes: a first drive part 510 arranged on the mounting bracket 100; wherein, the first drive part 510 has two output ends, the drive shaft 200 is divided into two shaft parts and is respectively connected to the two output ends of the first drive part 510.

[0065] The first drive part 510 is a speed reduction motor system. After the motor is decelerated by the speed reducer, torque is applied to the two shaft parts connected thereto, and then the first drive part 510 rotates relative to the drive shaft 200, achieving the technical effect that the drive shaft 200 does not rotate and the tailgate rotates. Compared with the traditional drive structure, this drive structure not only occupies less space, but also is convenient for installation and disassembly.

[0066] It should be noted that for the entire drive mechanism, the drive assembly 500 can only be used as a power component. If the load generated by the weight of the tailgate acts completely on the drive assembly 500, it will affect the performance of the drive assembly 500, and after a long time, the drive assembly 500 will be overloaded and damaged. Therefore, an auxiliary drive assembly 600 is provided to balance the weight of the tailgate through the auxiliary drive assembly 600.

[0067] It should be noted that the present application is a mechanism for driving the tailgate to rotate. To enable the tailgate to be firmly locked to the vehicle body, there is also a door lock assembly 700. Moreover, there are two door lock assemblies 700, which are respectively installed on both sides of the rear of the vehicle body, opposite to the upper end of the tailgate. When the tailgate is closed, the two door lock assemblies 700 are activated to lock the tailgate to the vehicle body. When the tailgate needs to be opened, one or both of them can be opened according to the actual situation.

[0068] Specifically, one of the door lock assemblies 700 is installed at an upper position on the movable plate 320, and the other door lock assembly 700 is installed on the side of the vehicle body and is opposite to the door lock assembly 700 on the movable plate 320. For the convenience of assembly, there is a vertically arranged side fixing plate 800 on the side of the fixed lock seat 410, and the side fixing plate 800 is exactly opposite to the movable plate 320, and the other door lock assembly 700 can be directly installed on the side fixing plate 800. When the tailgate needs to be opened by downward flipping, the two door lock assemblies 700 are unlocked simultaneously, so that the upper end of the tailgate is released from the restriction. At this time, the tailgate can be flipped along the axis of the drive shaft 200; when the tailgate needs to be opened by side flipping, the door lock assembly 700 on the side fixing plate 800 is opened, and the door lock assembly 700 on the movable plate 320 is closed. At this time, the tailgate can be flipped along the rotation axis of the hinge assembly 300.

[0069] It should be noted that according to actual needs, the drive assembly 500 further includes: a second drive part (not shown in the figure), which is used to drive the tailgate to rotate around the connecting shaft 330 as the rotation axis. For the second drive part, a power part that rotates by driving the connecting shaft 330 can be adopted, as long as it can be implemented, and there is no limitation.

[0070] Embodiment 2:

[0071] This embodiment is a further improvement based on Embodiment 1.

[0072] As Figures 1 - 5 shown, in this embodiment, the auxiliary drive assembly 600 includes: a first rotating arm 610, which can rotate around the drive shaft 200; and a first power-assisted strut 620, one end of which is arranged on the movable plate 320 and the other end is connected to the first rotating arm 610;

[0073] wherein, the first power-assisted strut 620 is a telescopic rod, and the first rotating arm 610 is connected to the tailgate; during the process of the tailgate being opened by downward flipping, the first power-assisted strut 620 provides an auxiliary thrust for the downward flipping of the tailgate.

[0074] When the tailgate flips downward, the actual force points of the tailgate are at the joints between the two shaft parts of the drive shaft 200 and the two output ends of the first drive part 510; when the tailgate flips to the side, the weight of the tailgate acts entirely on the joint between the drive shaft 200 and the movable plate 320. Therefore, an auxiliary drive assembly 600 is provided to balance the tailgate through the auxiliary drive assembly 600, so that the service life of the entire drive mechanism is longer.

[0075] Specifically, the auxiliary drive assembly 600 includes: a first rotating arm 610 and a first power-assisted strut 620; the first rotating arm 610 is installed on the tailgate, and then the upper end of the first power-assisted strut 620 is connected to the movable plate 320, and the lower end is connected to the first rotating arm 610. It should be noted that the first power-assisted strut 620 is a gas spring. When the tailgate flips downward, the first power-assisted strut 620 will extend under the action of its elastic force and act on the first rotating arm 610, and then the tailgate can not only quickly flip down, but also after flipping down to a certain angle, the first power-assisted strut 620 will have a pulling force on the first rotating arm 610 under the action of its spring, thereby slowing down the opening of the tailgate. That is to say, the tailgate is first opened to a certain angle at a faster speed, and then slowly opened to the maximum angle, so as to realize the high-efficiency control of the tailgate.

[0076] On the other hand, under the action of the first rotating arm 610, at this time, a part of the load corresponding to the weight of the tailgate is transferred from the first rotating arm 610 to the first power-assisted strut 620, and finally to the movable plate 320, thereby playing a role in balancing the tailgate.

[0077] It should be noted that the drive shaft 200 is arranged to pass through the first rotating arm 610, and the drive shaft 200 and the first rotating arm 610 are rotatably arranged through bearings. This arrangement not only facilitates the assembly of each component, but more importantly, increases the force point of the drive shaft 200, not only making the tailgate more stable when rotating, but also further balancing the weight of the tailgate.

[0078] In this embodiment, specifically, the first rotating arm 610 is of an L-shaped structure and is divided into a bottom plate 611 and a side plate 612. The bottom plate 611 and / or the side plate 612 are arranged on the tailgate, and the drive shaft 200 passes through the side plate 612 and is rotatably connected to the side plate 612.

[0079] Embodiment Three:

[0080] This embodiment is a further improvement based on Embodiment Two.

[0081] Such as Figures 1 - 5As shown, in this embodiment, the auxiliary drive assembly 600 further includes: a second rotating arm 630 rotatably disposed on the fixed lock base 410; and a second assist strut 640 having one end disposed on the vehicle body and the other end connected to the second rotating arm 630.

[0082] Wherein, the second assist strut 640 is a telescopic rod; during the process of the tailgate being turned down and opened, the second assist strut 640 applies a rotational thrust to the second rotating arm 630, and after the second rotating arm 630 rotates and abuts against the movable lock base 420, it applies a thrust to the movable lock base 420 and provides an auxiliary thrust for the tailgate to turn downwards.

[0083] To further improve the smoothness during the downward and sidewise turning of the tailgate, balance the weight of the tailgate, and reduce the load on the first drive part 510, a second rotating arm 630 and a second assist strut 640 are further provided. The second rotating arm 630 and the second assist strut 640 are disposed on the other side of the drive shaft 200 and are symmetrically arranged with the first rotating arm 610 and the first assist strut 620.

[0084] It should be noted that the second assist strut 640 has the same structure as the first assist strut 620 and is also a gas spring. The function of the second assist strut 640 is the same as that of the first assist strut 620, so no detailed description will be given here.

[0085] The embodiments of the present disclosure have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical application, or the improvement of the technology in the market, or to enable other ordinary skill in the art in the technical field to understand the disclosed embodiments.
