[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0032] In the description of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0033] The loading and unloading structure of the vehicle and the transport frame in the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] In the prior art, when loading a vehicle onto a transport frame or driving a vehicle out of a transport frame, since each wheel support structure corresponding to the vehicle wheels on the transport frame for supporting and fixing has a certain height, and for different vehicle models, the chassis height and axle length are different, this results in the vehicle chassis colliding with the wheel support structure during vehicle loading and unloading. At the same time, the vehicle needs to overcome a large resistance to drive into the wheel support structure.

[0035] To solve the above technical problems, an embodiment of the present application provides a loading and unloading structure for a vehicle, which is applied to a transport frame. The transport frame includes a rectangular chassis and two sets of wheel support structures; the rectangular chassis includes two cross beams and two side beams, and the two cross beams and the two side beams are joined together to enclose the rectangular chassis, and the two sets of wheel support structures are arranged inside the rectangular chassis; the loading and unloading structure includes a connection bridge and a guiding member; the connection bridge is arranged between the two sets of wheel support structures; the guiding member is arranged at one end of the connection bridge to guide the vehicle wheels from the connection bridge into the wheel support structures. By using the connection bridge and the guiding member to raise the vehicle wheels, the collision between the vehicle chassis and the wheel support structure is avoided, effectively improving the safety of vehicle loading and unloading; at the same time, by changing the height of the guiding member, the wheels can be gradually introduced into the wheel support structures, improving the vehicle loading and unloading efficiency. The following is a detailed description.

[0036] Refer to Figure 1 and Figure 4 , in an embodiment, the loading and unloading structure of the vehicle is applied to a transport frame 30, which includes a rectangular chassis 33, longitudinal beams 34, and two sets of wheel support structures. The rectangular chassis 33 includes two cross beams 331 and two side beams 332, and the cross beams 331 and the side beams 332 are joined end to end in sequence to enclose the rectangular chassis 33. The longitudinal beams 34 are perpendicular to the cross beams 331 and the side beams 332; the two sets of wheel support structures are arranged inside the rectangular chassis 33. In this embodiment, the two sets of wheel support structures are respectively arranged on the opposite side walls of the two cross beams 331 (i.e., arranged in Figure 1on the left and right sides shown); the loading and unloading structure of the vehicle includes a connecting bridge 10 and a guiding member 20. The connecting bridge 10 is arranged between two sets of wheel hub support structures; the guiding member 20 is arranged at one end of the connecting bridge 10 to connect with the wheel hub support structure near this end, so as to guide the vehicle wheel hub from the connecting bridge 10 into the wheel hub support structure. In this embodiment, the guiding member 20 is arranged with an inclined slope, that is, lower on the left and higher on the right ( Figure 4 in the perspective view, the same below), and can gradually guide the wheel hub from the connecting bridge 10 into the wheel hub support structure.

[0037] It should be noted that in this embodiment, the two sets of wheel hub support structures are respectively arranged on the opposite side walls of two cross beams 331 only as a specific implementation form. In actual application, there is no limitation on the installation position and installation method of the wheel hub support structure. The two sets of the wheel hub support structures arranged in the rectangular chassis are all within the protection scope of this application.

[0038] For the convenience of description, the two sets of wheel hub support structures are respectively the first wheel hub support structure 31 and the second wheel hub support structure 32, that is, the first wheel hub support structure 31 is on the left side and the second wheel hub support structure 32 is on the right side ( Figure 1 in the perspective view). In actual use, the connecting bridge 10 in this embodiment is arranged between the first wheel hub support structure 31 and the second wheel hub support structure 32 of the vehicle frame 30, that is, one end of the connecting bridge 10 abuts against the first wheel hub support structure 31, and the other end of the connecting bridge 10 abuts against the second wheel hub support structure 32. The space between the first wheel hub support structure 31 and the second wheel hub support structure 32 is raised by the connecting bridge 10 and the guiding member 20, so that the height of the end of the connecting bridge 10 close to the first wheel hub support structure 31 is the same as that of the first wheel hub support structure 31, and the highest ( Figure 4 in the perspective view, the same below) position of the guiding member 20 is the same as the height of the second wheel hub support structure 32; when loading the vehicle, the vehicle reverses into the vehicle frame 30 from the first wheel hub support structure 31 to the second wheel hub support structure 32. The rear wheels of the vehicle first pass through the first wheel hub support structure 31 and then drive onto the top surface of the connecting bridge 10 ( Figure 4 in the perspective view). Due to the arrangement of the connecting bridge 10, the rear wheels of the vehicle will not lower in height after passing through the first wheel hub support structure 31, thus avoiding the collision between the vehicle chassis and the first wheel hub support structure 31. Then continue to reverse. Due to the left-low and right-high arrangement of the guiding member 20, the rear wheels of the vehicle are gradually lifted in height after passing through the guiding member 20 until the rear wheels enter the second wheel hub support structure 32. At this time, the front wheels fall into the first wheel hub support structure 31, and the loading of the vehicle on the vehicle frame 30 is completed. Then the connecting bridge 10 and the guiding member 20 are withdrawn and recycled for repeated use.

[0039] It should be noted that the form in which one end of the connecting bridge 10 abuts against the first hub support structure 31 and the other end of the connecting bridge 10 abuts against the second hub support structure 32 can be: both the head and the tail ends of the connecting bridge 10 abut against the first hub support structure 31 and the second hub support structure 32 respectively. It can also be that one of the head and the tail ends of the connecting bridge 10 abuts against one of the first hub support structure 31 or the second hub support structure 32, and the guiding member 20 is arranged between the connecting bridge 10 and the other hub support structure. It can be understood that, for example, when the guiding member 20 is stacked on the connecting bridge 10, it is in a state where both the head and the tail ends of the connecting bridge 10 abut against the first hub support structure 31 and the second hub support structure 32 respectively. When the guiding member 20 is juxtaposed with the connecting bridge 10, the guiding member 20 is arranged between the connecting bridge 10 and the other hub support structure.

[0040] In this embodiment, during the loading process of the vehicle, the height of the rear wheel is continuously raised through the connecting bridge 10 and the guiding member 20 and then enters the second hub support structure 32, avoiding the collision between the vehicle chassis and the first hub support structure 31 and the second hub support structure 32. At the same time, since the guiding member 20 has a slope setting, the vehicle can enter the second hub support structure 32 without having to overcome a large force, improving the loading efficiency of the vehicle and being able to meet the use of various vehicles with different chassis heights. In addition, when the vehicle is unloaded from the transport frame 30, the connecting bridge 10 and the guiding member 20 are placed between the first hub support structure 31 and the second hub support structure 32, and the vehicle is directly driven out of the transport frame 30. The specific unloading process is similar to the loading process and will not be elaborated here. In some embodiments, the vehicle loading is not limited to the reverse mode, and the vehicle can also be directly driven into the transport frame 30 according to requirements, the on-site loading situation, etc.

[0041] It should be noted that in this embodiment, the guiding member 20 is set to be lower on the left and higher on the right ( Figure 1 in the perspective), that is, the surface of the guiding member 20 that contacts the vehicle wheel (that is, Figure 4 the top surface of the guiding member 20 in the perspective, the same below) is in an inclined state, and can guide and raise the wheel from the connecting bridge 10 to the second hub support structure 32; and in this embodiment, the dimension of the guiding member 20 in the longitudinal direction ( Figure 4 the up and down direction in this, that is, the extending direction of the longitudinal beam 34, the same below) gradually increases from the first hub support structure 31 to the second hub support structure 32, and is linearly increased. At this time, the surface of the guiding member 20 that contacts the wheel is set to be a plane (as Figure 8 shown).

[0042] In some embodiments, the surface of the guiding member 20 that contacts the wheel can also increase non-linearly. For example, the surface of the guiding member 20 that contacts the wheel is a curved surface or composed of multiple planes spliced together (that is, Figure 4 in the perspective, the surface of the guiding member 20 that contacts the wheel is in a broken line shape).

[0043] In some embodiments, the longitudinal dimension of the guide member 20 first increases and then decreases, that is, the middle bulge of the guide member 20 in the extending direction of the side beam 332 is the highest point (the guide member 20 is arched). After the wheel hub enters the guide member 20 from the connecting bridge 10, the height of the wheel hub first rises. After passing through the highest point, the wheel hub passes through the rear section of the guide member 20 and its height is lowered until it enters the second wheel hub support structure 32. This setting can, after the wheel hub enters the second wheel hub support structure 32 (i.e., when the vehicle is mounted on the transport frame 30), the protruding part of the guide member 20 can block the wheel hub and prevent the wheel hub from rolling out of the second wheel hub support structure 32 with a relatively high height, improving the safety of loading the vehicle on the transport frame 30. Of course, in this setting, the protruding part of the guide member 20 will not collide with the vehicle chassis either; with such a setting, it can meet the use of guiding the wheel hub from the connecting bridge 10 to be raised to the second wheel hub support structure 32; the shape setting of the guide member 20 can guide the wheel hub to the second wheel hub support structure 32 and will not cause collision to the vehicle chassis.

[0044] In addition, in some embodiments, anti-slip protrusions can also be provided on the surface of the guide member 20 in contact with the wheel to prevent the wheel from slipping when passing through the guide member 20 during the process of loading and unloading the vehicle, which affects the stability and loading and unloading efficiency of the vehicle during loading and unloading. In some embodiments, one end of the connecting bridge 10 close to the first wheel hub support structure 31 may not be at the same height as the first wheel hub support structure 31, and may also be slightly lower or higher than the first wheel hub support structure 31, and one end of the guide member 20 close to the second wheel hub support structure 32 may also be slightly lower or higher than the second wheel hub support structure 32, as long as the vehicle can enter and exit smoothly without bumping the chassis during vehicle loading and unloading.

[0045] Please refer to Figure 4 and Figure 6 , in an embodiment, the guide member 20 is provided at one end of the connecting bridge 10 and is stacked above the connecting bridge 10 ( Figure 4 in the perspective view). In this embodiment, since the guide member 20 is stacked above the connecting bridge 10 and the guide member 20 borrows the height of the connecting bridge 10, the height that the guide member 20 needs to lift the wheel hub is relatively small, reducing the material consumption and weight of the guide member 20, and the assembly is convenient, facilitating the handling of the connecting bridge 10 and the guide member 20 during loading and unloading and reducing the labor intensity.

[0046] It should be noted that referring to Figure 5In one embodiment, the guide member 20 is disposed between the connecting bridge 10 and the second hub support structure 32, that is, one end of the guide member 20 abuts against one end of the connecting bridge 10 close to the second hub support structure 32, and the other end abuts against the second hub support structure 32. In this embodiment, the guide member 20 can increase the length of the connecting bridge 10 in the extending direction of the side beam 332, that is, when the length of the connecting bridge 10 is not enough to connect the first hub support structure 31 and the second hub support structure 32, the guide member 20 in this embodiment can play the role of extending the connecting bridge 10 and can guide the wheel hub into the second hub support structure 32.

[0047] It should also be noted that, regardless of whether the guide member 20 is disposed on the top surface of the connecting bridge 10 or between the connecting bridge 10 and the second hub support structure 32, the guide member 20 and the connecting bridge 10 may be integrally or separately disposed, depending on specific usage conditions.

[0048] See also Figure 2 , Figure 5 , Figure 8 as well as Figure 9 In one embodiment, the guide member 20 is provided with a rotating shaft 26 and a buckle arm 27, and the connecting bridge 10 is provided with a limiting protrusion 28. The above-mentioned buckle arm 27 is rotatably set on the side wall of the above-mentioned guide member 20 facing the side beam 332 through the rotating shaft 26, and the limiting protrusion 28 is set on the side wall of the connecting bridge 10 facing the side beam 332. The above-mentioned buckle arm 27 is buckled on the above-mentioned limiting protrusion 28 to fix the relative position of the guide member 20 and the connecting bridge 10 in the longitudinal direction, that is, to ensure that the guide member 20 will not be displaced longitudinally, and the guide member 20 will not collide with the chassis of the vehicle when the vehicle is loaded and unloaded.

[0049] It should be noted that when loading and unloading the vehicle, the end of the guide member 20 close to the second wheel hub support structure 32 is subjected to the weight of the vehicle, and the end of the guide member 20 away from the second wheel hub support structure 32 may tilt up; and when the end of the guide member 20 away from the second wheel hub support structure 32 is ready to tilt up, since the above-mentioned buckle arm 27 is buckled on the limiting protrusion 28, the buckle arm 27 is forced to pull the limiting protrusion 28, thereby limiting the longitudinal displacement of the end of the guide member 20 away from the second wheel hub support structure 32, that is, preventing the end of the guide member 20 away from the second wheel hub support structure 32 from tilting up, thereby ensuring that the chassis is protected from collision when the guide member 20 tilts up.

[0050] In this embodiment, the above-mentioned buckle arm 27 includes a first sub-arm 271 and a second sub-arm 272. The first sub-arm 271 is connected to the rotating shaft 26, and the second sub-arm 272 is connected to the end of the first sub-arm 271 away from the rotating shaft 26. The connection between the first sub-arm 271 and the second sub-arm 272 is set at an angle, and the limiting protrusion 28 abuts between the first sub-arm 271 and the second sub-arm 272.

[0051] It should be noted that the first sub-arm 271 and the second sub-arm 272 form a hook shape. In this embodiment, the included angle between the first sub-arm 271 and the second sub-arm 272 is 90°. In some embodiments, it can also be set at other angles, which is set according to factors such as the position of the rotating shaft 26 and the size of the limiting protrusion 28. By rotating the rotating shaft 26, the buckle arm 27 hooks the limiting protrusion 28, which can prevent the end of the guide member 20 away from the second wheel hub support structure 32 from tilting up, and can also prevent the guide member 20 from moving in the extending direction of the side beam 332. In this embodiment, the buckle arm 27 hooks the limiting protrusion 28 from below (as shown in Figure 6 ), and in some embodiments, the buckle arm 27 can also hook the limiting protrusion 28 from above (as shown in Figure 7 ); in some embodiments, the buckle arm 27 can also be set in other forms, not limited to this.

[0052] At the same time, in this embodiment, the guide member 20 is provided with an adjustment groove 21 on the side wall facing the side beam 332. The adjustment groove 21 is in a long strip shape. In this embodiment, the adjustment groove 21 extends along the extending direction of the side beam 332. The rotating shaft 26 is slidably connected in the adjustment groove 21, and the rotating shaft 26 can displace along the first direction X in the adjustment groove 21. The position of the buckle arm 27 can be adjusted to meet the use of different limiting protrusions 28, improving the overall adaptability. In some embodiments, the above adjustment groove 21 can also extend in other directions to meet the position adjustment of the buckle arm 27; or the first sub-arm 271 is telescopic, and the position of the second sub-arm 272 is adjusted by the telescopic of the first sub-arm 271 to meet the use requirements of the buckle arm 27 buckling on the limiting protrusion 28.

[0053] Refer to Figure 1 、 Figure 3 、 Figure 6 and Figure 8 , in an embodiment, the guide member 20 is arranged on the top surface of the connecting bridge 10, and the guide member 20 and the connecting bridge 10 are separately arranged; in this embodiment, the guide member 20 is provided with an end connecting ear 23, and the connecting bridge 10 is provided with a fixing plate 24 adapted to the end connecting ear 23. The end connecting ear 23 and the fixing plate 24 are fixedly connected by a connecting bolt 25, realizing the fixed connection between the connecting bridge 10 and the guide member 20; making the guide member 20 stable relative to the connecting bridge 10 during the loading and unloading process of the vehicle.

[0054] It should be noted that through the above - mentioned settings of the end - connecting ear 23, the fixing plate 24 and the connecting bolt 25, when loading the vehicle, the guide member 20 will not displace in the extending direction of the side beam 332 due to contact with the wheel (receiving the frictional force of the wheel), ensuring the stable and reliable loading of the vehicle. In some embodiments, the connection between the guide member 20 and the connection bridge 10 can also be in other ways. For example, the end - connecting ear 23 and the fixing plate 24 can be connected together by riveting; or the guide member 20 and the connection bridge 10 can be fixed by welding.

[0055] In addition, in an embodiment, the above - mentioned end - connecting ear 23 has a fixing portion 231 and a connecting portion 232. The fixing portion 231 is fixedly arranged on the side wall of the guide member 20 facing the second hub support structure 32. The above - mentioned connecting portion 232 extends along the extending direction of the side beam 332. With such a setting, the end - connecting ear 23 will not protrude beyond the highest point of the guide member 20 in the longitudinal direction, that is, the connecting bolt 25 will not protrude, and it will not affect the safe passage of the wheel. The above - mentioned fixing plate 24 is fixedly arranged on the side wall of the connection bridge 10 facing the second hub support structure 32. At the same time, in order to adapt to the connecting portion 232, the fixing plate 24 also extends along the extending direction of the side beam 332. A first through - hole 2321 is provided on the connecting portion 232, and a second through - hole 241 is provided on the fixing plate 24. The orthographic projection of the first through - hole 2321 on the abutting surface of the connecting portion 232 and the fixing plate 24 overlaps at least partially with the orthographic projection of the second through - hole 241 on the abutting surface of the connecting portion 232 and the fixing plate 24. With such a setting, it can be ensured that the connecting bolt 25 can smoothly penetrate through the first through - hole 2321 and the second through - hole 241 to tightly connect the connecting portion 232 and the fixing plate 24 together.

[0056] It should be noted that in some embodiments, the above - mentioned first through - hole 2321 and the second through - hole 241 can be long - strip - shaped through - holes. With such a setting, it can provide sufficient assembly allowance and facilitate the connection between the connecting portion 232 (end - connecting ear 23) and the fixing plate 24.

[0057] Refer to Figure 6 and Figure 8 , in an embodiment, the above - mentioned end - connecting ear 23 further has a limiting portion 233. The limiting portion 233 is arranged between the fixing portion 231 and the connecting portion 232. The limiting portion 233 extends towards the connection bridge 10, that is, the limiting portion 233 extends longitudinally downward ( Figure 6extends in the perspective; when the limiting portion 233 abuts against the side wall of the connecting bridge 10 facing the second hub support structure 32, the orthographic projections of the first through hole 2321 and the second through hole 241 on the abutting surface of the connecting portion 232 and the fixing plate 24 overlap at least; with such a setting, the positions of the first through hole 2321 and the second through hole 241 can be quickly positioned through the above-mentioned limiting portion 233, the quick installation of the connecting bolt 25 can be realized, and the installation efficiency of the guiding member 20 can be improved; at the same time, when the vehicle is loaded, the static friction of the hub on the guiding member 20 will cause the guiding member 20 to receive a force from the second hub support structure 32 towards the first hub support structure 31, and the above-mentioned limiting portion 233 can offset part of the force, avoiding the connecting portion 232, the fixing plate 24 and the connecting bolt 25 from being deformed due to receiving a large force, which affects subsequent use.

[0058] Refer to Figure 3 , Figure 6 and Figure 8 , in an embodiment, the guiding member 20 is provided with a connecting plate 22, and in this embodiment, the connecting plate 22 is arranged on the side wall of the guiding member 20 facing the second hub support structure 32, the connecting plate 22 extends along the extending direction of the side beam 332, and a plurality of pin holes 221 are provided on the connecting plate 22, and there are four pin holes 221 in this embodiment; when the vehicle is loaded and unloaded, one end of the connecting bridge 10 is abutted against the first hub support structure 31, and the guiding member 20 is abutted against the second hub support structure 32. At this time, the guiding member 20 is connected to the second hub support structure 32 by passing a pin 222 through the pin hole 221, preventing the connecting bridge 10 and the guiding member 20 from displacing in the extending direction of the side beam 332 when the vehicle is loaded and unloaded. In some embodiments, the end of the connecting bridge 10 abutting against the first hub support structure 31 can also be arranged in this way; the displacement of the connecting bridge 10 and the guiding member 20 in the extending direction of the side beam 332 is limited by the pin 222, and the structure is simple and the disassembly and assembly are convenient.
