Description

Technical Field

[0001] This application relates to the field of gooseneck balls, and more particularly to a novel gooseneck ball. Background Technology

[0002] Currently, more and more users in the domestic market are starting to use and engage in outdoor sports, including products such as RVs, trailers, and yachts. These large products require a trailer connection with the vehicle during use so that the RV, trailer, and yacht can move.

[0003] Generally, a gooseneck ball consists of a ball body and a mounting part. The gooseneck ball is mounted on a mounting seat at the rear of the vehicle, which securely connects the mounting part to the mounting seat at the rear of the vehicle. A trailer ball cover is installed on the front of a motorhome, trailer, or yacht. The trailer ball cover can press and fix the ball body of the gooseneck ball inside the trailer ball cover to complete the trailer connection between the motorhome, trailer, yacht, and the vehicle.

[0004] Regarding the above-mentioned technical solutions, the existing gooseneck ball bearing capacity is insufficient, which makes the gooseneck ball prone to breakage when used for trailers. Summary of the Invention

[0005] To improve the load-bearing capacity of the gooseneck ball, this application provides a novel gooseneck ball.

[0006] The novel gooseneck ball provided in this application adopts the following technical solution:

[0007] A novel gooseneck ball, comprising:

[0008] A spherical portion, which is used to connect with a trailer ball cover;

[0009] The mounting part is fixedly connected to the ball part and is used to connect with the mounting base;

[0010] The reinforcing part is located between the sphere and the mounting part. The reinforcing part includes at least one reinforcing rib. Each reinforcing rib is fixedly disposed in the sphere and extends to the mounting part, or each reinforcing rib is fixedly disposed in the mounting part and extends to the sphere.

[0011] By adopting the above technical solution, when using a gooseneck ball for towing, the mounting part of the gooseneck ball is fixedly connected to the mounting seat of the car or other trailer vehicle, and then the spherical part of the gooseneck ball is fixedly connected to the trailer ball cover of the RV, yacht or other towed vehicle. This allows the trailer vehicle to tow the towed vehicle. During towing, because the reinforcing part is located between the spherical part and the mounting part, and the reinforcing rib extends from the spherical part to the mounting part, or vice versa, the connection strength between the mounting part and the spherical part is better, thus improving the load-bearing capacity of the gooseneck ball. This makes the gooseneck ball less prone to breakage when used for towing, improving the problem of insufficient load-bearing capacity of existing gooseneck balls, which leads to easy breakage when using them for towing.

[0012] Optionally, the reinforcing part further includes a reinforcing top piece, which is located between the spherical part and the reinforcing rib. The reinforcing top piece is connected to the spherical part or to the mounting part, and one side of the reinforcing top piece is fixedly connected to the reinforcing rib.

[0013] Optionally, the reinforcing part further includes a reinforcing base plate, which is located between the mounting part and the reinforcing rib. The reinforcing base plate is connected to the mounting part or to the spherical part, and one side of the reinforcing base plate is connected to the reinforcing rib.

[0014] Optionally, the reinforcing part further includes one or more reinforcing plates, which are connected to the spherical part or to the mounting part;

[0015] Furthermore, the reinforcing sheet and each of the reinforcing ribs are fixedly connected.

[0016] Optionally, the axis of the sphere portion does not coincide with the axis of the mounting portion.

[0017] Optionally, the reinforcing ribs are arranged parallel to each other.

[0018] Optionally, the reinforcing part further includes one or more reinforcing connecting pieces, one end of each reinforcing connecting piece being fixedly connected to the spherical part, and the other end of each reinforcing connecting piece being fixedly connected to the mounting part.

[0019] Optionally, the axis of the sphere coincides with the axis of the mounting portion.

[0020] Optionally, each of the reinforcing ribs is evenly distributed circumferentially around the axis of the sphere or mounting portion.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] When using a gooseneck ball for towing, the mounting part of the gooseneck ball is fixedly connected to the mounting bracket of the car or other trailer vehicle. Then, the ball part of the gooseneck ball is fixedly connected to the trailer ball cover of the RV, yacht, or other towed vehicle, allowing the trailer vehicle to tow the towed vehicle. During towing, because the reinforcing part is located between the ball part and the mounting part, and the reinforcing rib extends from the ball part to the mounting part, or vice versa, the connection strength between the mounting part and the ball part is better, thus improving the load-bearing capacity of the gooseneck ball. This makes the gooseneck ball less prone to breakage when towing, improving the problem of insufficient load-bearing capacity of existing gooseneck balls, which leads to easy breakage when using them for towing.

[0037] The following is in conjunction with the appendix Figure 1-13 This application will be described in further detail.

[0038] This application discloses a novel gooseneck ball.

[0041] Reference Figures 1 to 4 The spherical part 1 includes a spherical segment 11, an arc segment 12, and a cylindrical segment 13. The spherical segment 11, the arc segment 12, and the cylindrical segment 13 are fixedly connected in sequence. The spherical segment 11 is spherical. The diameter of the arc segment 12 gradually decreases from the end near the cylindrical segment 13 to the end near the spherical segment 11. The cylindrical segment 13 is cylindrical.

[0042] Reference Figures 1 to 4 The mounting part 2 includes a connecting section 21 and a main body section 22. The connecting section 21 is fixedly connected to the cylindrical section 13, and the main body section 22 is fixedly connected to the connecting section 21. The main body section 22 is rectangular. A central hole 222 is provided in the middle of the main body section 22. Connecting holes 221 are provided on both sides of the main body section 22 that are directly opposite each other. Both connecting holes 221 are connected to the central hole 222.

[0043] Reference Figures 1 to 4The reinforcing part 3 includes two reinforcing ribs 31, a reinforcing top piece 32, and a reinforcing connecting piece 33. The two reinforcing pieces 35 are fixedly disposed on the outer peripheral surface of the cylindrical section 13 and extend along the connecting section 21.

The reinforcing top piece 32 is fixedly disposed on the outer peripheral surface of the cylindrical section 13, and one side of the reinforcing top piece 32 is fixedly connected to both reinforcing ribs 31. One end of the reinforcing connecting piece 33 is fixedly connected to the spherical part 1, and the other end of the reinforcing connecting piece 33 is fixedly connected to the mounting part 2.

[0044] The implementation principle of Embodiment 1 is as follows: When using a gooseneck ball for towing, the mounting part 2 of the gooseneck ball is fixedly connected to the mounting seat of the car or other trailer vehicle. Then, the ball part 1 of the gooseneck ball is fixedly connected to the trailer ball cover of the RV, yacht or other towed vehicle, thereby enabling the trailer vehicle to tow the towed vehicle. During towing, because the reinforcing part 3 is located between the ball part 1 and the mounting part 2, and the reinforcing rib 31 extends from the ball part 1 to the mounting part 2, the connection strength between the mounting part 2 and the ball part 1 is better, thereby improving the load-bearing capacity of the gooseneck ball. As a result, the gooseneck ball is less likely to break when used for towing, improving the problem of insufficient load-bearing capacity of existing gooseneck balls, which leads to easy breakage when using them for towing.
