Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a trailer bar and a motorhome. Background Technology

[0002] With the increasing popularity of motorhomes, the demand for personalization is becoming more and more apparent. If bicycles, motorcycles, etc. are placed inside the motorhome, they will take up a lot of space. Therefore, bicycles, motorcycles, etc. are usually connected to the motorhome's trailer bumper through special frames and other components, and then placed on the special frames.

[0003] Currently, trailer bars that can be used to install special vehicle frames generally adopt a three-port design. The two side ports are used to install the special vehicle frame, and the middle port is used to install the tow hook. Existing trailer bars are generally fixed in design, and the spacing between the two side ports cannot be adjusted, which limits their use and makes them unsuitable for installation on different vehicle frames. Therefore, they generally need to be customized according to the spacing of the vehicle frame ports.

[0004] Therefore, in order to address the aforementioned technical issues, it is necessary to provide a trailer bumper and a motorhome.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1 to 4 As shown, a trailer bar in one embodiment of the present invention includes: a pair of main connectors 1 and a pair of frame connecting devices 2.

[0029] like Figures 1 to 2 As shown, a connecting sleeve 102 is fixed to one end of each pair of main connecting parts 1, and a main horizontal plate 103 is fixed on the pair of connecting sleeves 102. A first connector 104 is fixed to the middle of the side wall of the main horizontal plate 103 away from the main connecting parts 1. By installing the pair of main connecting parts 1 onto the vehicle frame, the trailer bar is installed. The first connector 104 is mainly used to install the trailer hook for trailer use.

[0030] Secondly, a first reinforcing rib 108 is fixed on the port of the first connector 104, and two pairs of first positioning holes 109 are drilled on the two side walls of the first connector 104. The first reinforcing rib 108 is used to increase the strength of the port of the first connector 104. A trailer hook is installed on the first connector 104 so that a pin is inserted into the first positioning hole 109, thereby fixing the trailer hook on the first connector 104.

[0031] like Figures 1 to 2 As shown, each of the pair of main connectors 1 has a connecting groove 101. The main connector 1 is clamped onto the beam of the vehicle through the connecting groove 101 and then fixed with bolts.

[0032] like Figures 1 to 2 As shown, a C-shaped reinforcing plate 105 is fixed between the first connector 104 and the main cross plate 103, and an auxiliary connector 106 is fixed to the upper end of the C-shaped reinforcing plate 105. The first connector 104 is mainly used to install a trailer hitch. When the first connector 104 is towing, it is mainly subjected to lateral tension. Therefore, the C-shaped reinforcing plate 105 is used to strengthen the connection strength between the first connector 104 and the auxiliary connector 106. In addition, the auxiliary connector 106 can be fixed to the rear bumper beam or frame of the vehicle to enhance the support of the main cross plate 103.

[0033] like Figures 1 to 2 As shown, a reinforcing rib 107 is fixed between the auxiliary connector 106 and the C-shaped reinforcing plate 105. The reinforcing rib 107 is used to increase the connection strength between the auxiliary connector 106 and the C-shaped reinforcing plate 105.

[0034] like Figures 1 to 4 As shown, a pair of frame connecting devices 2 are installed on the main cross plate 103. Each pair of frame connecting devices 2 includes a movable sleeve 201. The movable sleeve 201 slides on the main cross plate 103. A second connector 202 is fixed on the side of the movable sleeve 201 near the first connector 104. The second connector 202 is used to connect the connecting tube of the frame. According to the spacing of different frame connecting tubes, the position of the movable sleeve 201 is slid on the main cross plate 103 to adjust the spacing of the pair of second connectors 202 to match the connecting tubes installed on the frame.

[0035] In addition, a fixing plate 203 is fixed to both sides of the first connector 104 at the bottom of the main horizontal plate 103, and a pair of clamping plates 204 are fixed to the bottom of the movable sleeve 201. The pair of clamping plates 204 are located on both sides of the fixing plate 203. Multiple second positioning holes 205 are evenly drilled on the fixing plate 203. Two pairs of fifth positioning holes 217 are drilled on the pair of clamping plates 204, which correspond to any two of the second positioning holes 205. A threaded sleeve 207 is fixed to one of the clamping plates 204 at each of the pair of fifth positioning holes 217. A first bolt 206 is installed in each of the two pairs of fifth positioning holes 217. After the movable sleeve 201 is moved to a suitable position on the main horizontal plate 103, the two pairs of fifth positioning holes 217 can correspond to any two of the second positioning holes 205. Then, the first bolt 206 is tightened on the threaded sleeve 207, locking the pair of clamping plates 204 onto the fixing plate 203, thereby fixing the movable sleeve 201.

[0036] Secondly, a second reinforcing rib ring 210 is fixed on the port of the second connector 202, and two pairs of third positioning holes 209 are drilled on the two side walls of the second connector 202. A longitudinal support component 211 is installed on the second connector 202. The second reinforcing rib ring 210 is used to increase the strength of the port of the first connector 104. After the external connecting tube is inserted into the second connector 202, the external connecting tube is fixed in the second connector 202 by inserting the second bolt 216 into the third positioning hole 209.

[0037] like Figures 1 to 4 As shown, the longitudinal support assembly 211 includes a retainer 212, which is snapped onto the upper end of the second connector 202. The retainer 212 is located on the outside of the second connector 202 and a support plate 213 is fixed thereon. The retainer 212 is snapped onto the second connector 202, and then the support plate 213 provides a certain longitudinal support force to the connecting pipe connected to the second connector 202.

[0038] like Figures 1 to 4 As shown, the sleeve 212 has a groove 214 that matches the second reinforcing ring 210. When the longitudinal support component 211 is installed on the second connector 202, it slides on the second reinforcing ring 210 through the groove 214, thereby locking the longitudinal support component 211 on the second connector 202, and at the same time aligning the two pairs of fourth positioning holes 215 with the two pairs of third positioning holes 209.

[0039] like Figures 1 to 4 As shown, the inner wall dimension of the support plate 213 is consistent with the inner diameter dimension of the second connector 202, so that the inner wall of the support plate 213 is tightly fitted with the outer wall of the connecting pipe connected to the second connector 202, so that the support plate 213 effectively supports the external connecting pipe.

[0040] like Figures 1 to 4 As shown, the sleeve 212 has two pairs of fourth positioning holes 215 corresponding to the positions of the third positioning holes 209. After the longitudinal support component 211 is engaged on the second connector 202, the two pairs of fourth positioning holes 215 are aligned with the two pairs of third positioning holes 209. Then, the outer connecting pipe is fixed to the second connector 202 by the second bolt 216, and the longitudinal support component 211 is also fixed to the second connector 202.

[0041] like Figures 1 to 4 As shown, a support rib 208 is fixed between the bottom of the second connector 202 and the side wall of the movable sleeve 201. The support rib 208 provides longitudinal support for the second connector 202, thereby providing support for the second connector 202.

[0042] An embodiment of this utility model also provides a motorhome, which includes the aforementioned trailer bar.

[0043] Working principle: When using this device, the connection slot 101 is snapped into the workshop and then fixed with bolts to complete the installation of the device. When towing is required, the trailer hook is inserted into the first connector 104 and then the pin is inserted into the first positioning hole 109 to fix the trailer hook. After fixing, the trailer can be used for towing.

[0044] When a special frame needs to be installed, first measure the distance between the connecting tubes on both sides of the frame, then unscrew the first bolt 206 from the fifth positioning hole 217, and then slide the movable sleeve 201 on the main cross plate 103. The movable sleeve 201 drives the second connector 202 to move and adjust the position of the second connector 202. After the adjustment is completed, insert the first bolt 206 into the fifth positioning hole 217 and tighten it on the threaded sleeve 207, thereby completing the fixing of the movable sleeve 201.

[0045] Next, install the longitudinal support assembly 211 onto the second connector 202. During installation, align the slide groove 214 with the second reinforcing ring 210, and insert the longitudinal support assembly 211 downwards. The retaining sleeve 212 is then secured to the upper end of the second connector 202. Subsequently, insert the connecting tube of the frame into the second connector 202. If the frame has three connecting tubes, install the longitudinal support assembly 211 onto the first connector 104 using the same method. Then, insert the middle connecting tube into the first connector 104. Next, insert the second bolt 216 into the third positioning hole 209 and the fourth positioning hole 215 to fix the longitudinal support assembly 211. At this point, the support plate 213 can provide a longitudinal support force for the connecting tube in the frame, thus completing the frame installation.
