[0039] Reference Figures 1 to 8 A gooseneck-type hanging device, comprising:

[0040] A first track 11 and a second track 12 are arranged in parallel. The first track 11 is provided with a first connecting hole 111, and the second track 12 is provided with a second connecting hole 121 corresponding to the first connecting hole 111. The first track 11 and the second track 12 are used to connect to the carriage.

[0041] Device body 2, wherein the device body 2 is provided with a third connecting hole 211 and a fourth connecting hole 221;

[0042] Goose neck head 23, which is connected to the main body 2 of the device and is used to connect to the towed vehicle;

[0043] When the main body 2 of the device is connected to the first track 11 and the second track 12, the first connecting hole 111 and the third connecting hole 211 are correspondingly provided to allow a connector to be inserted; the second connecting hole 121 and the fourth connecting hole 221 are correspondingly provided to allow another connector to be inserted.

[0044] The above-described structure provides a simple, stable, and easy-to-install gooseneck mounting device.

[0045] For example, when the gooseneck-type coupling device described in this application is installed in the vehicle body, the first track 11 and the second track 12 are arranged in parallel to form a symmetrical rigid frame structure, which can evenly distribute the vertical load of the coupling device, such as the weight of the towed vehicle, to both sides of the vehicle body, avoiding structural deformation or tilting caused by single-point force, effectively suppressing left and right swaying after coupling, and improving stability during driving; and when the main body 2 of the device is connected to the first track 11 and the second track 12, it is only necessary to insert one connector into the first connecting hole 111 and the third connecting hole 211 to fix them relatively, and insert another connector into the second connecting hole 121 and the fourth connecting hole 221 to fix them relatively, so as to achieve overall fixation, which greatly simplifies the installation process and shortens the coupling time, especially suitable for scenarios that require frequent disassembly and assembly.

[0046] In this embodiment, the number of the first connecting hole 111 and the second connecting hole 121 is at least two, and the first connecting hole 111 is arranged along the extension direction of the first track 11, and the second connecting hole 121 is arranged along the extension direction of the second track 12. When the device body 2 is connected to the first track 11 and the second track 12, the third connecting hole 211 is arranged corresponding to one of the first connecting holes 111, and the fourth connecting hole 221 is arranged corresponding to one of the second connecting holes 121.

[0047] With the above structure, the main body 2 of the device can select different fixed points in the extension directions of the first track 11 and the second track 12 to adapt to different usage requirements and scenarios.

[0048] For example, uneven weight distribution of goods during transportation can easily cause problems such as warping of the vehicle body. By setting multiple connecting holes distributed along the extension direction of the first track 11 and the second track 12, the position of the coupling point can be flexibly adjusted according to the different centers of gravity of the towed vehicle, which can effectively prevent the warping and deformation of the vehicle body, extend the service life of the vehicle body, and protect driving safety.

[0049] In this embodiment, both the first track 11 and the second track 12 are provided with a fixing part 13, which is used to allow the first track 11 and the second track 12 to be connected to the carriage.

[0050] The aforementioned structure allows for the even distribution of loads, such as traction force and cargo weight, from the mounting device to the main body of the truck bed. For example, the fixing part 13 employs a multi-bolt connection or a large-area contact design, effectively converting concentrated force into distributed force and reducing the risk of localized deformation of the truck bed. Taking a pickup truck bed as an example, when towed by a tractor, the fixing part 13 connects to the truck bed frame through multiple bolt holes, preventing tearing of the sheet metal caused by single-point stress.

[0051] In this embodiment, the fixing part 13 includes a fixing hole 131 and a fastener 132. The fastener 132 is inserted into and protrudes from the fixing hole 131 for connection to the vehicle body.

[0052] With the above-described structure, the fastener 132 only needs to be inserted into and pass through the fixing hole 131, and then connected to the carriage to complete the stable connection between the first track 11 and the second track 12 and the carriage. It does not require special tools or complex processes, shortens the installation time, and when the fixing part 13 is worn, it only needs to replace the fastener 132, without having to completely disassemble the hanging device, which greatly reduces maintenance costs.

[0053] In this embodiment, the edge of the main body 2 of the device protrudes downward to form a third connecting part 21 and a fourth connecting part 22. The third connecting hole 211 is located on the third connecting part 21, and the fourth connecting hole 221 is located on the fourth connecting part 22. The middle parts of the first track 11 and the second track 12 both protrude upward. The middle part of the first track 11 is provided with a first mounting hole 112. The shape and size of the first mounting hole 112 match the third connecting part 21. The middle part of the second track 12 is provided with a second mounting hole 122. The shape and size of the second mounting hole 122 match the fourth connecting part 22. The third connecting part 21 is inserted into and passes through the first mounting hole 112, and the fourth connecting part 22 is inserted into and passes through the second mounting hole 122.

[0054] The above structure effectively prevents the main body 2 of the device from shifting in the horizontal and rotational directions, and also simplifies the installation process and makes it convenient for users.

[0055] For example, when the towed vehicle turns, the lateral centrifugal force is transmitted to the third connecting part 21 and the fourth connecting part 22 through the gooseneck head 23. At this time, the third connecting part 21 and the fourth connecting part 22 will have a tendency to move horizontally and rotate. At this time, the hole walls of the first mounting hole 112 and the second mounting hole 122 can respectively abut against the sides of the third connecting part 21 and the fourth connecting part 22, effectively restricting the third connecting part 21 and the fourth connecting part 22 from producing horizontal displacement and rotation.

[0056] In this embodiment, the first connecting holes 111 are symmetrically distributed along the axis of the middle part of the first track 11, and the two first connecting holes 111 symmetrically distributed along the axis of the middle part of the first track 11 form a first symmetrical connecting hole group 11a. The second connecting holes 121 are symmetrically distributed along the axis of the middle part of the second track 12, and the two second connecting holes 121 symmetrically distributed along the axis of the middle part of the second track 12 form a second symmetrical connecting hole group 12a. When the device body 2 is connected to the first track 11 and the second track 12, the third connecting hole 211 and the first symmetrical connecting hole group 11a are used to allow one connector to be inserted, and the fourth connecting hole 221 and the second symmetrical connecting hole group 12a are used to allow another connector to be inserted.

[0057] By configuring the structure described above, lateral loads perpendicular to track 1, such as bending moments and torques, are evenly distributed to the connection points on both sides, preventing track 1 from shifting or deforming due to unilateral force. For example, when the main body 2 of the device is subjected to lateral force, the symmetrical first connection hole 111 and the third connection hole 211 form a "two-point constraint," converting the force into a symmetrical pressure along the axis rather than an eccentric moment. Furthermore, the symmetrically distributed first connection hole 111 and the symmetrically distributed second connection hole 121 also facilitate installation by the user.

[0058] In this embodiment, the main body 2 of the device is rectangular in shape, the number of the third connecting holes 211 is at least two, and the two third connecting holes 211 are respectively located at two vertices on the side of the main body 2 of the device that is close to the first track 11, and the number of the fourth connecting holes 221 is at least two, and the two fourth connecting holes 221 are respectively located at two vertices on the side of the main body 2 of the device that is close to the first track 11.

[0059] By setting the above structure, a uniform and symmetrical force-bearing structure can be formed. When the main body 2 of the device is subjected to the force from the towed vehicle, the force from the towed vehicle can be effectively distributed and offset by the four-point connection.

[0060] In this embodiment, the main body 2 of the device is also provided with a hook-up hole 24, which is used to allow the hook of the towing vehicle to be engaged.

[0061] The above-mentioned structure can further enhance the stability of the connection between the gooseneck coupling device and the towed vehicle.

[0062] For example, when the hook is engaged in the hook hole 24 and the gooseneck head 23 is connected to the towed vehicle, if the gooseneck head 23 deforms and breaks due to uneven stress, the auxiliary connection setting of the hook engaging in the hook hole 24 can effectively avoid the risk of the device falling off during towing and causing an accident, increasing the connection strength between the gooseneck hook device of this application and the towed vehicle. In addition, the hook hole 24 can also be used independently to improve the scenario applicability of the gooseneck hook device of this application.

[0063] In this embodiment, the main body 2 of the device is provided with a clamping plate 25, the lower end of the goose neck head 23 extends through the lower side of the main body 2 of the device, the clamping plate 25 is connected to the lower end of the goose neck head 23, and the upper part of the clamping plate 25 abuts against the lower side of the main body 2 of the device.

[0064] With the above structure, when the gooseneck 23 is subjected to the pulling force of the towing vehicle, the force is transmitted to the clamping plate 25 through the gooseneck 23. The upper abutment surface of the clamping plate 25 disperses the force to the bottom frame of the main body 2, effectively avoiding deformation or breakage caused by single-point force at the connection between the gooseneck 23 and the main body, and enhancing the connection strength.

[0065] In this embodiment, the lower side of the device body 2 is also provided with a snap-fit ​​part 26, and the snap-fit ​​plate 25 is connected to the snap-fit ​​part 26.

[0066] With the above-described structure, the clamping plate 25 can not only distribute the vertical force received to the device body 2 through abutment, but also distribute it through the clamping part 26, further enhancing its structural strength in the vertical direction. When the device is subjected to a horizontal impact force, the abutment surface between the clamping plate 25 and the lower side of the body can offset part of the horizontal force through frictional resistance, and the connection between the clamping part 26 and the clamping plate 25 can also resist the remaining impact through a rigid structure.

[0067] The above description provides one or more embodiments in conjunction with specific content, and does not imply that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the protection scope of this utility model.
