Description

Technical Field

[0001] This utility model relates to the field of automotive technology, and more particularly to the field of tractor parts technology. Specifically, it is a side skirt flipping mechanism for automobiles. Background Technology

[0002] Traditional tractor side skirts are primarily used to protect components on both sides of the vehicle body and also serve a decorative purpose. Traditional side skirts typically use fixed or simple hinged connections, but they suffer from the following problems:

[0003] Fixed side skirts cannot be opened and need to be disassembled for inspection and maintenance, which is time-consuming and labor-intensive. For example, when inspecting vehicle chassis components or changing tires, fixed side skirts restrict the operating space. When the vehicle is driving on rough roads or roads with high shoulders, the side skirts are easily damaged by collisions. Furthermore, with the increasing use of new energy battery-swapping tractor vehicles, traditional pit-type battery-swapping stations occupy a large space, and the side battery-swapping mechanism cannot pass through the fixed side skirts, thus failing to achieve the purpose of battery swapping.

[0004] While a simple hinge connection can enable the opening and closing of side skirts, traditional side skirt opening and closing mechanisms lack assist devices and require considerable force to operate. This is especially true for larger side skirts, where operation becomes more difficult, resulting in inconvenient opening and closing, strenuous operation, and a lack of flexibility. Furthermore, the absence of limiting devices makes it easy for the side skirts to wobble or detach.

[0005] Therefore, developing a flexible, flip-up side skirt mechanism is key to solving these problems. Utility Model Content

[0006] The purpose of this utility model is to provide a car side skirt flipping mechanism to solve the problems of existing fixed side skirts that require disassembly during maintenance, limit operating space, are prone to collisions, and are not suitable for pit-type battery swapping stations. It also solves the problems of inconvenient opening and closing and laborious operation of simple hinge connection methods.

[0007] The present invention solves the above problems through the following technical solution:

[0008] A car side skirt flipping mechanism includes:

[0009] Fixed bracket, installed on the longitudinal beams of the car frame;

[0010] The main support rod has one end hinged to the first end of the fixed bracket and the other end fixedly connected to the first support provided on the side skirt of the car.

[0011] The flip-up bracket includes a first telescopic rod and a second telescopic rod. The first end of the first telescopic rod is hinged to the second end of the fixed bracket, and the second end of the first telescopic rod is hinged to a second support provided on the main support rod. The first end of the second telescopic rod is hinged to a third support provided on the side skirt plate, and the second end of the second telescopic rod is hinged to a fourth support provided on the main support rod. The second support, the first telescopic rod, the fourth support, and the second telescopic rod are respectively located on both sides of the main support rod.

[0012] Furthermore, the first telescopic rod and the second telescopic rod are respectively equipped with a travel self-limiting device.

[0013] Furthermore, the travel self-limiting device is a limit block or a limit pin.

[0014] Furthermore, both ends of the first telescopic rod are detachably and fixedly connected to the fixed bracket and the second support, respectively.

[0015] Furthermore, the two ends of the second telescopic rod are detachably and fixedly connected to the fourth support and the third support, respectively.

[0016] Furthermore, both ends of the main support rod are detachably and fixedly connected to the fixed bracket and the first support, respectively.

[0017] Furthermore, both the first and second telescopic rods are air struts.

[0018] Furthermore, both the first and second telescopic rods are equipped with a self-locking structure for self-locking of the telescopic stroke.

[0019] Furthermore, the first telescopic rod and the second telescopic rod are electric telescopic rods or hydraulic telescopic rods.

[0020] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0021] (1) This utility model has a simple structure, is easy to manufacture and install; it is easy to operate and can easily flip the side skirts, thus improving work efficiency.

[0022] (2) This utility model is equipped with a travel self-limiting device, which can effectively prevent the side skirt from overturning and improve safety.

[0023] (3) This utility model is equipped with a self-locking device for the gas strut stroke. When the side skirt is flipped to a horizontal or vertical position, it can be automatically locked to prevent the side skirt from shaking unexpectedly during driving.

[0024] (4) This utility model is applicable to various types of tractor vehicles and has good versatility.

[0025] (5) The flipping structure of this utility model adopts a high-strength hinge connection method, which enables the side skirt to flip smoothly around a fixed axis. The hinge is specially designed to have good wear resistance and fatigue resistance, ensuring smooth flipping during long-term use.

[0026] (6) This invention achieves the side skirts without mechanical power, using external force (manual) to lift them, or it can be driven electrically or hydraulically. The driver can easily flip the side skirts using the control buttons inside the vehicle. The electric drive system is responsive and easy to operate; the hydraulic drive system provides greater torque and is suitable for heavier side skirts.

[0027] (7) This utility model is applicable to a variety of application scenarios: During vehicle maintenance, the side skirts can be easily flipped up, providing ample operating space for maintenance personnel, greatly shortening maintenance time and improving work efficiency; when the vehicle is driving on complex road conditions, the driver can flip the side skirts in time to avoid collisions between the side skirts and obstacles, reducing maintenance costs. Under normal driving conditions, the side skirts can effectively block airflow, reduce air resistance, reduce fuel consumption, and achieve the goal of energy conservation and emission reduction.

[0028] (8) This utility model can be applied not only to newly produced tractors, but also to existing vehicles through modification. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the embodiments, but the implementation of the present invention is not limited thereto.

[0033] Example:

[0034] Combined with appendix Figure 1 and Figure 2 As shown, a car side skirt flipping mechanism includes:

[0035] Fixed bracket 1 is installed on the longitudinal beam of the vehicle frame to support the entire tilting mechanism;

[0036] The main support rod 3 has one end hinged to the first end of the fixed bracket 1 and the other end fixedly connected to the first support 8 provided on the side skirt 7 of the car; it is used to drive the side skirt 7 to rotate.

[0037] The flip-up support includes a first telescopic rod 4 and a second telescopic rod 6. The first end of the first telescopic rod 4 is hinged to the second end of the fixed support 1, and the second end of the first telescopic rod 4 is hinged to a second support 5 on the main support rod 3. The first end of the second telescopic rod 6 is hinged to a third support 10 on the side skirt 7, and the second end of the second telescopic rod 6 is hinged to a fourth support 9 on the main support rod 3. The second support 5, the first telescopic rod 4, the fourth support 9, and the second telescopic rod 6 are located on opposite sides of the main support rod 3. The first telescopic rod 4 and the second telescopic rod 6 enable bidirectional flipping of the side skirt 7.

[0038] Furthermore, the first telescopic rod 4 and the second telescopic rod 6 are respectively equipped with stroke self-limiting devices. The stroke of the first telescopic rod 4 and the second telescopic rod 6 is naturally limited to restrict the flipping angle of the side skirt 7 and prevent the side skirt 7 from flipping excessively.

[0039] Furthermore, the travel self-limiting device is a limit block or a limit pin. The flip angle of the side skirt 7 can be adjusted according to actual needs.

[0040] Furthermore, the two ends of the first telescopic rod 4 are respectively connected to the fixed bracket 1 and the second support 5 via bolt assembly 2.

[0041] Furthermore, the two ends of the second telescopic rod 6 are respectively connected to the fourth support 9 and the third support 10 via bolt assembly 2.

[0042] Furthermore, the two ends of the main support rod 3 are connected to the fixed bracket 1 and the first support 8 respectively through bolt assembly 2.

[0043] The flip bracket and the side skirt 7 are connected by bolts and nuts, which facilitates disassembly and maintenance.

[0044] Furthermore, both the first telescopic rod 4 and the second telescopic rod 6 are air struts. The air struts are hinged to the fixed bracket 1, and the ends of the struts are hinged to the flipping bracket, which provides the power for the side skirt 7 to flip.

[0045] Furthermore, both the first telescopic rod 4 and the second telescopic rod 6 are equipped with a self-locking structure for self-locking of the telescopic stroke. When the side skirt 7 is flipped to a horizontal or vertical position, it can automatically lock to prevent the side skirt from accidentally shaking during driving.

[0046] Working principle:

[0047] When the side skirt 7 needs to be opened, manually lift the side skirt 7 upwards. The piston rod of the first telescopic rod 4 (such as an air strut, also called a pneumatic strut or gas spring) extends, pushing the main support rod 3 to rotate around the hinge point (at the second support 5), thereby causing the side skirt 7 to flip upwards. At the same time, the piston rod of the second telescopic rod 6 extends, pushing the side skirt 7 to rotate around the hinge point (at the fourth support 9), thus achieving the state where the side skirt 7 is opened vertically without occupying horizontal space. When the side skirt 7 needs to be closed, the piston rod of the first telescopic rod 4 retracts, pulling the main support rod 3 to rotate in the opposite direction, thereby causing the side skirt 7 to flip downwards. At the same time, the piston rod of the second telescopic rod 6 retracts, pushing the side skirt 7 to rotate around the hinge point (at the third support 10) until it fits against the vehicle body.

[0048] Furthermore, the first telescopic rod 4 and the second telescopic rod 6 are electric telescopic rods or hydraulic telescopic rods.

[0049] Although the present invention has been described herein with reference to illustrative embodiments, the above embodiments are merely preferred embodiments of the present invention, and the implementation of the present invention is not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and implementations, which will fall within the scope and spirit of the principles disclosed in this application.
