Description

Technical Field

[0001] This utility model relates to the field of automotive parts, specifically to a trailer rack pedal. Background Technology

[0002] A trailer hitch step (also known as a tow bar step or trailer connection step) is an auxiliary device installed near the trailer hitch (trailer frame) or at the rear of the trailer, primarily used for:

[0003] Easy trailer connection: Provides a step platform for users to operate the trailer hook, attach trailers, or adjust the towing device.

[0004] Safe loading and unloading of trailers: Some trailers come with a folding step at the rear for easy loading and unloading of goods or inspection of the trailer's condition (such as RVs and cargo trailers).

[0005] Off-road and rescue scenarios: When towing a stuck vehicle or in complex terrain, the pedals provide stable operating support.

[0006] Since trailer rack steps are often used in complex environments, they require a certain level of strength. Therefore, a trailer rack step with sufficient structural strength is urgently needed in the market. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a trailer frame pedal.

[0008] To achieve the above objectives, the basic solution of this utility model is as follows:

[0009] A trailer frame step includes a main frame and connecting rods connected to each other. The main frame includes a crossbar, a first bow-shaped rod, and a second bow-shaped rod. The crossbar connects the two ends of the first bow-shaped rod, and the two ends of the second bow-shaped rod are connected to the crossbar. The crossbar forms a first plane and a second plane with the first bow-shaped rod and the second bow-shaped rod, respectively. The included angle between the first plane and the second plane is 80°~100°. A short rod connects the first bow-shaped rod and the second bow-shaped rod. A step is provided on the first plane.

[0010] Compared with the prior art, the trailer rack step of this application has the following advantages:

[0011] The trailer frame step of this application forms a first plane and a second plane by setting a crossbar, a first bow-shaped rod and a second bow-shaped rod. The first plane and the second plane form an included angle, making the overall cross section of the main frame triangular. At the same time, the crossbar and the first bow-shaped rod respectively form a shape that is also close to a triangle, which is sufficient to support the strength of the trailer frame step under various working conditions. In addition, the crossbar, the first bow-shaped rod and the second bow-shaped rod are all made of circular tubes. The cross section of the circular tube is axisymmetric and centrally symmetric, and the moment of inertia in all directions is the same. This allows the load to be evenly distributed around the tube wall, reducing local stress concentration, thereby making the structure of the main frame more stable and stronger.

[0012] Preferably, the angle between the first plane and the second plane is 90°.

[0013] Beneficial effects: The 90° angle between the first and second planes allows the second plane to fit more closely to the car's trunk lid after the trailer hitch is installed. In special circumstances, the car's trunk lid can provide support for the crossbar and the second bow-shaped bar.

[0014] Preferably, the short rod is connected at the middle position of the first bow-shaped rod and the second bow-shaped rod.

[0015] Beneficial effect: This configuration makes the overall structure of the main frame more stable.

[0016] Preferably, the crossbar, the first bow-shaped bar, the second bow-shaped bar, the connecting plate, and the short bar are all made of aluminum alloy or steel.

[0017] Beneficial effects: The use of high-strength aluminum alloy and steel materials ensures the strength of the main frame.

[0018] Preferably, a connecting plate is provided on the second plane.

[0019] Beneficial effects: The connecting plate enhances the connection strength between the crossbar and the second bow-shaped bar, and the connecting plate can also be used to connect the connecting rod.

[0020] Preferably, the connecting plate is located at the middle position of the connecting crossbar and the second bow-shaped bar.

[0021] Beneficial effect: This configuration makes the overall structure of the main frame more stable.

[0022] Preferably, a connecting seat is provided at one end of the connecting rod, and the connecting seat is detachably connected to the connecting plate.

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: main frame 1, connecting rod 2, crossbar 3, first bow-shaped rod 4, second bow-shaped rod 5, short rod 6, pedal 7, connecting plate 8, pin hole 9, and connecting seat 10.

[0032] As attached Figure 1-2 As shown in the figure, this embodiment illustrates a trailer rack step, including a main frame 1 and a connecting rod 2 connected to each other. The connecting rod 2 is used to connect a car. A step platform is provided on the main frame 1 to facilitate users to operate the trailer hook, attach a trailer, or adjust the towing device. At the same time, it is convenient to load and unload goods or check the status of the trailer. In towing a stuck vehicle or in complex terrain, the step can provide stable operating support.

[0033] Specifically, the main frame 1 includes a crossbar 3, a first bow-shaped rod 4, and a second bow-shaped rod 5. The crossbar 3 connects to both ends of the first bow-shaped rod 4, and both ends of the second bow-shaped rod 5 are connected to the crossbar 3. The crossbar 3 is located within the first bow-shaped rod 4, meaning that both ends of the crossbar 3 do not exceed the length of the first bow-shaped rod 4; similarly, both ends of the second bow-shaped rod 5 do not exceed the length of the crossbar 3.

[0034] The crossbar 3 forms a first plane and a second plane with the first bow-shaped bar 4 and the second bow-shaped bar 5, respectively. The angle between the first plane and the second plane is 80°~100°. A short bar 6 connects the first bow-shaped bar 4 and the second bow-shaped bar 5. The short bar 6 enhances the supporting force of the main frame 1. At least one short bar 6 is provided, and the short bars 6 are evenly distributed between the first bow-shaped bar 4 and the second bow-shaped bar 5.

[0036] The main frame 1 has a triangular cross-section, and the crossbars 3, together with the first bow-shaped bar 4 and the second bow-shaped bar 5, also form shapes that are close to triangles, which is sufficient to support the strength of the trailer frame steps under various working conditions. In addition, the crossbars 3, the first bow-shaped bar 4 and the second bow-shaped bar 5 are all made of circular tubes. The cross-section of the circular tubes is axially symmetric and centrally symmetric, and the moment of inertia in all directions is the same. This allows the load to be evenly distributed around the tube wall, reducing local stress concentration, and thus making the main frame structure more stable and stronger.

[0037] Specifically, in this embodiment, the included angle between the first plane and the second plane is set to 90°, so that the crossbar 3 and the second bow-shaped bar 5 of the second plane fit the car better, and in some cases, the rear of the car provides better support for the crossbar 3 and the second bow-shaped bar 5.

[0038] A connecting plate 8 is provided on the second plane. The connecting plate 8 is used to connect the connecting rod 2.

[0039] The short rod 6 connects the middle of the first bow-shaped rod 4 and the second bow-shaped rod 5. The connecting plate 8 connects the middle of the crossbar 3 and the second bow-shaped rod 5.

[0040] The above settings make the overall structure of the main frame 1 more stable.

[0041] In another embodiment, a connecting seat 10 is provided at one end of the connecting rod 2, and the connecting seat 10 is detachably connected to the connecting plate 8. Specifically, the detachable connection can be a screw connection. The connecting rod 2 achieves its connection to the main frame 1 by fixing it to the connecting plate via the connecting seat 10.

[0042] Specifically, the crossbar 3, the first bow-shaped bar 4, the second bow-shaped bar 5, the connecting plate 8, and the short bar 6 are all made of aluminum alloy or steel. The crossbar 3 is welded to the first bow-shaped bar 4, the crossbar 3 is welded to the second bow-shaped bar 5, the short bar 6 is welded to the first bow-shaped bar 4, the short bar 6 is welded to the second bow-shaped bar 5, the connecting plate 8 is welded to the first bow-shaped bar 4, and the connecting plate 8 is welded to the second bow-shaped bar 5.

[0043] The connecting rod 2 is a rectangular tube with pin holes 9 on both sides. The pin holes 9 are used for inserting the rod to connect the trailer frame step and the car.
