Description

Technical Field

[0001] This utility model relates to vehicle structure, specifically to a rear towing assembly and a vehicle. Background Technology

[0002] With the increasing popularity of automobiles and the rise of camping and self-driving tours, consumers' demands for vehicle storage space are showing a diversified and upgrading trend. Traditional car trunks, due to space limitations, can no longer meet the needs of long-distance self-driving tours and outdoor equipment transportation, giving rise to auxiliary transportation solutions such as roof racks and trailers. Currently, the mainstream rear-mounted towing assemblies generally adopt a rigid connection design (such as fixed interfaces or ball joint coupling devices). This rigid connection design has two major drawbacks: first, it affects the overall aesthetics; second, it is prone to causing greater damage to following vehicles in a rear-end collision, which is widely criticized. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a rear towing assembly and a vehicle, wherein the tow hook assembly is detachable and the signal adapter mounting base is rotatable, thereby ensuring an aesthetically pleasing appearance and reducing the risk of damage to rear-end collision vehicles when the rear towing assembly is not in use.

[0004] A rear tow assembly according to this utility model includes a mounting bracket, a tow hook assembly, a locking seat, and a signal adapter mounting seat. The locking seat is fixedly connected to the mounting bracket, the tow hook assembly is detachably connected to the locking seat, and the signal adapter mounting seat is rotatably connected to the mounting bracket.

[0005] Furthermore, it also includes a mounting beam and a signal adapter body. The left and right ends of the mounting beam are respectively provided with vehicle body connecting plates.

[0034] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0035] like Figures 1-3 As shown, a rear tow assembly in this embodiment includes a mounting bracket 1, a tow hook assembly 2, a locking seat 3, and a signal adapter mounting seat 4. The locking seat 3 is fixedly connected to the mounting bracket 1, the tow hook assembly 2 is detachably connected to the locking seat 3, and the signal adapter mounting seat 4 is rotatably connected to the mounting bracket 1.

[0036] The tow hook assembly 2 is detachable, and the signal adapter mounting base 4 is rotatable. Therefore, when using the rear towing assembly, the tow hook assembly 2 can be installed, and the signal adapter mounting base 4 can be rotated to a lower position to facilitate the towing of trailers, RVs, or other equipment by the tow hook assembly 2, and to facilitate the connection of the signal adapter body 6 on the signal adapter mounting base 4 with the electrical system of the trailer, RV, or other equipment, providing power and switch control signals for the turn signals, reversing lights, etc. of the towed trailer, RV, or other equipment. When the rear towing assembly is not in use, the tow hook assembly 2 can be removed and the signal adapter mounting bracket 4 can be rotated to a higher position. After the tow hook assembly 2 is removed, it can be stored in the vehicle's trunk or other locations. Rotating the signal adapter mounting bracket 4 to a higher position brings the signal adapter mounting bracket 4 closer to the mounting beam 5. When the vehicle is viewed from the rear, the signal adapter mounting bracket 4 is hidden inside the vehicle body, which does not affect the aesthetics of the rear of the vehicle. This effectively solves the problem of unsightly exposed structures and reduces the risk of damage to rear-end collision vehicles.

[0037] In this embodiment, as Figure 2 and Figure 3 As shown, the rear towing assembly also includes a mounting beam 5 and a signal adapter body 6. The left and right ends of the mounting beam 5 are respectively provided with vehicle body connecting plates 501. The mounting bracket 1 is fixedly connected to the middle of the mounting beam 5. The signal adapter body 6 is connected to the signal adapter mounting seat 4.

[0038] The body connecting plate 501 of the mounting beam 5 can be bolted to the vehicle's body structure, providing greater strength for towing. The signal adapter body 6 is used to connect to the electrical systems of trailers, RVs, or other equipment.

[0039] In this embodiment, as Figure 1 , Figure 4 and Figure 9 As shown, the mounting bracket 1 is provided with a receiving groove 101 for mounting the locking seat 3. A mounting lug 102 is provided on one side of the mounting bracket 1, and a mounting hook 103 is provided on the mounting lug 102. The mounting hook 103 includes a longitudinal rod segment 1031 and a transverse rod segment 1032 connected to the lower part of the longitudinal rod segment 1031. The length of the longitudinal rod segment 1031 is along the vertical direction, and the length of the transverse rod segment 1032 is along the front-back direction. The longitudinal rod segment 1031 is connected to the mounting lug 102. The mounting lug 102 and the longitudinal rod segment 1031 are connected by bolts.

[0040] In this embodiment, as Figure 8 and Figure 9As shown, a limiting member is installed at the rear of the crossbar segment 1032; a mounting sleeve 401 is provided on the signal adapter mounting base 4, which is rotatably connected to the crossbar segment 1032. A contact portion 402 is provided at the front of the mounting sleeve 401. An elastic element 403 and a support ring 404 are provided inside the mounting sleeve 401. The support ring 404 is rotatably engaged with the crossbar segment 1032. The two ends of the elastic element 403 abut against the support ring 404 and the limiting member, respectively. When the elastic element 403 is in a contracted state, the elastic force of the elastic element 403 causes the support ring 404 to have a forward movement tendency so that the contact portion 402 abuts against the longitudinal segment 1031. The elastic element 403 can be a spring.

[0041] By applying a force backward, the signal adapter mounting base 4 moves backward, reducing the distance between the support ring 404 of the mounting sleeve 401 and the limiting piece 1035 of the limiting member. The support ring 404 and the limiting piece 1035 further compress the elastic element 403, and the contact part 402 separates from the longitudinal rod section 1031. At this time, the signal adapter mounting base 4 can rotate up and down around the axis of the transverse rod section 1032. After releasing the signal adapter mounting base 4 and stopping the force applied to it, under the elastic force of the elastic element 403, the support ring 404 of the mounting sleeve 401 moves forward, and the signal adapter mounting base 4 moves forward as a whole. The elastic force of the elastic element 403 allows the contact part 402 to abut against the longitudinal rod section 1031. The elastic force of the elastic element 403 acting on the support ring 404 can press the contact part 402 tightly against the longitudinal rod section 1031. At this time, the friction between the contact part 402 and the longitudinal rod section 1031 keeps them relatively stationary.

[0042] In this embodiment, as Figure 9 As shown, the crossbar segment 1032 is provided with a stepped portion 1033 and a screw portion 1034. The screw portion 1034 is located on the rear side of the stepped portion 1033. The limiting member includes a limiting piece 1035 and a nut sleeve 1036. The nut sleeve 1036 is threadedly connected to the screw portion 1034. The nut sleeve 1036 presses and fixes the limiting piece 1035 on the stepped portion 1033.

[0043] The elastic element 403 is sleeved on the crossbar section 1032, and the elastic element 403 is compressed and fixed between the limiting piece 1035 and the support ring 404.

[0044] In this embodiment, as Figure 5 and Figure 7As shown, the locking seat 3 is provided with a front limiting part 301, a insertion cavity 302, and a rear limiting part 303. The insertion cavity 302 is disposed inside the locking seat 3, and the front limiting part 301 and the rear limiting part 303 are spaced apart in the front-to-back direction. The front limiting part 301 and the rear limiting part 303 are respectively located on different sides of the insertion cavity 302. After the locking seat 3 is placed in the receiving groove 101, the locking seat 3 is connected to the mounting bracket 1 by threaded fasteners such as bolts and nuts.

[0045] In this embodiment, as Figures 5-7 As shown, the tow hook assembly 2 includes a tow hook body 201, a drive component 202, and a pin body 203. The upper part of the pin body 203 is provided with a limiting groove 2031. The tow hook body 201 includes a connecting portion 2011 for cooperating with the locking seat 3. The connecting portion 2011 has a mounting cavity extending vertically. The mounting cavity includes a pin mounting cavity 20111 and a drive mounting component disposed on the lower side of the pin mounting cavity 20111. Cavity 20112, the top of the connecting part 2011 is provided with a hook part 20113 for conformally engaging with the rear limiting part 303. When the hook part 20113 is connected to the rear limiting part 303, the driving member 202 can drive the pin body 203 to move upward in the pin mounting cavity 20111 until the upper end of the pin body 203 abuts against the hook part 20113 and the front limiting part 301 on the front and rear sides respectively.

[0046] In this embodiment, the driving component 202 includes a driving handle and a driving rod. The upper part of the driving rod is connected to the lower part of the pin body 203. The lower part of the driving rod is provided with a rack structure, and the driving handle is provided with a gear structure that meshes with the rack structure.

[0047] By rotating the drive handle, the rack and pinion structure can be rotated, which in turn drives the drive rod to move up and down, thereby driving the pin body 203 to move up and down.

[0048] When installing the tow hook assembly 2, firstly, rotating the drive handle causes the rack structure to rotate forward, which in turn moves the drive rod and the pin body 203 downward until the pin body 203 retracts into the pin mounting cavity 20111. Then, the connecting part 2011 is inserted into the insertion cavity 302, and the hook part 20113 is connected to the rear limiting part 303. Finally, rotating the drive handle causes the rack structure to rotate in the opposite direction, which in turn moves the drive rod and the pin body 203 upward until the upper end of the pin body 203 extends out of the pin mounting cavity 20111. The limiting groove 2031 fits snugly against the front limiting part 301. At this time, the front and rear sides of the upper end of the pin body 203 abut against the hook part 20113 and the front limiting part 301, respectively. The upper end of the pin body 203 prevents the hook part 20113 and the tow hook assembly 2 from moving back and forth. The hook part 20113 and the rear limiting part 303 cooperate to prevent the hook part 20113 and the tow hook assembly 2 from moving downward. The limiting groove 2031 of the pin body 203 prevents the pin body 203 and the tow hook assembly 2 from moving upward. Therefore, the installation and fixation of the tow hook assembly 2 are achieved.

[0049] When disassembling the tow hook assembly 2, the drive handle is rotated to drive the rack structure to rotate forward, which in turn drives the drive rod and the pin body 203 to move downward. The limiting groove 2031 of the pin body 203 gradually moves away from the front limiting part 301 until the pin body 203 moves downward to the position where it retracts into the pin mounting cavity 20111. At this time, the hook part 20113 can move forward and separate from the rear limiting part 303. After separation, the hook part 20113 and the entire tow hook assembly 2 can move downward, thereby removing the tow hook assembly 2.

[0050] In this embodiment, as Figure 6 As shown, the tow hook body 201 also includes a tow hook portion 2012 disposed on the front side of the connecting portion 2011, and the tow hook portion 2012 is provided with a ball head.

[0051] One vehicle in this embodiment includes the aforementioned rear towing assembly.
