Description

Technical Field

[0001] This invention relates to the field of automotive accessories technology, and more particularly to a trailer basket. Background Technology

[0002] A trailer basket is an accessory installed on the rear of a vehicle to carry luggage, tools, outdoor equipment, and other items, effectively compensating for insufficient loading space in pickup truck cargo boxes or passenger car trunks.

[0003] Currently, most common trailer baskets use a fixed installation structure. The height of the load-bearing surface of the trailer square tube installed at the rear of the vehicle cannot be adjusted according to actual usage needs. Since the loading and unloading height is fixed, users need to frequently bend over or lift heavy objects during operation, which is inconvenient and labor-intensive, resulting in a significantly poor user experience.

[0004] Therefore, there is an urgent need for a trailer basket to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a trailer basket to solve the problem that the height of the trailer basket in the prior art cannot be adjusted, which leads to inconvenience in loading and unloading operations, high labor intensity, and a significantly poor user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A trailer basket is installed at the rear of a vehicle. The trailer basket includes a basket, a support mechanism, and a mounting mechanism. The mounting mechanism is installed at the rear of the vehicle. The support mechanism includes a linkage bracket and a position holding assembly. One side of the linkage bracket is connected to the basket, and the other side is connected to the mounting mechanism. The height of one side of the linkage bracket relative to the mounting mechanism is adjustable. The position holding assembly is able to maintain the height of one side of the linkage bracket relative to the mounting mechanism.

[0008] In some embodiments, the linkage bracket includes a first linkage, a second linkage, and a third linkage. The second linkage is arranged parallel to the mounting mechanism. One end of the first linkage is hinged to one end of the second linkage, and the other end is hinged to the mounting mechanism. The second linkage is connected to the basket. One end of the third linkage is hinged to the middle of the second linkage, and the other end is hinged to the mounting mechanism. The position holding component is capable of maintaining the angle between the first linkage and the mounting mechanism, as well as the angle between the third linkage and the mounting mechanism, to maintain the second linkage at a height equivalent to that of the mounting mechanism.

[0009] In some embodiments, the position holding assembly includes an adjustable damping element, one end of which is hinged to the first link and the other end of which is hinged to the mounting mechanism. The adjustable damping element is capable of providing an adjustable damping force to the first link. When the first link rotates about a rotation point, the adjustable damping element is capable of providing a damping force to the first link that is lower than a first preset value. When maintaining the angle between the first link and the mounting mechanism, the adjustable damping element is capable of providing a damping force to the first link that is higher than a second preset value.

[0010] In some embodiments, the position holding assembly further includes a damping adjustment switch, which includes an operating handle and a pull rope. One end of the pull rope is connected to the operating handle, and the other end is connected to one end of the adjustable damping element. Driving the operating handle can adjust the damping force provided by the adjustable damping element to the first connecting rod.

[0011] In some embodiments, the position holding assembly further includes a locking member, wherein a set of fixing holes is provided on the side of the third link away from the second link, and the locking member can pass through the set of fixing holes and abut against the mounting mechanism to fix the angle between the third link and the mounting mechanism.

[0012] In some embodiments, the locking element includes a locking block and a locking pin, the fixing hole group includes two fixing holes arranged coaxially, the locking block is installed between the two fixing holes, and the locking pin can be sequentially inserted into one of the fixing holes, the locking block and the other fixing hole to press the locking block against the mounting mechanism.

[0013] In some embodiments, the locking member further includes an anti-detachment pin, which includes a bent section, a middle section and an anti-detachment section connected in sequence. When the locking pin passes through one of the fixing holes, the locking block and the other fixing hole, the bent section and the anti-detachment section are located on both sides of the third link, and an anti-detachment hole is provided on the anti-detachment section, and the anti-detachment pin passes through the anti-detachment hole.

[0014] In some embodiments, notches are provided at both ends of the first link and at both ends of the third link.

[0015] In some embodiments, the trailer basket further includes a protective plate mounted on the mounting mechanism and located on the side of the mounting mechanism away from the trailer basket.

[0016] In some embodiments, both the first connecting rod and the third connecting rod are hinged to the mounting mechanism via a hinge shaft. The top of the protective plate has a first connecting plate and a second connecting plate disposed opposite to each other. The first connecting plate has two first connecting holes, and the second connecting plate has two second connecting holes. The two first connecting holes and the two second connecting holes correspond one-to-one. The hinge shaft on the first connecting rod can pass through one of the first connecting holes and the second connecting hole corresponding to one of the first connecting holes. The hinge shaft on the third connecting rod can pass through the other first connecting hole and the second connecting hole corresponding to the other first connecting hole.

[0017] The beneficial effects of this invention are:

[0018] This invention provides a trailer basket installed at the rear of a vehicle. The trailer basket includes a basket, a support mechanism, and a mounting mechanism. The mounting mechanism is installed at the rear of the vehicle. The support mechanism includes a linkage bracket and a position holding component. One side of the linkage bracket is connected to the basket, and the other side is connected to the mounting mechanism. The height of one side of the linkage bracket relative to the mounting mechanism is adjustable. The position holding component maintains the height of one side of the linkage bracket relative to the mounting mechanism. With this configuration, one side of the linkage bracket is connected to the basket, and the other side is connected to the mounting mechanism. The height of one side of the linkage bracket relative to the mounting mechanism is adjustable. When the height of the basket needs to be adjusted, the height of one side of the linkage bracket relative to the mounting mechanism can be adjusted, thereby adjusting the height of the basket relative to the mounting mechanism. After adjusting the height of the basket, the position holding component maintains the height of one side of the linkage bracket relative to the mounting mechanism, thus maintaining the height of the basket relative to the mounting mechanism. This allows users to flexibly adjust the load-bearing height of the basket according to actual needs. Users do not need to frequently bend over or lift heavy objects during operation, reducing the labor intensity of loading and unloading, and facilitating operation, thus improving the user experience.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0032] This embodiment provides a trailer basket that solves the problem in the prior art where the height of the trailer basket cannot be adjusted, resulting in inconvenient loading and unloading operations, high labor intensity, and a significantly poor user experience.

[0033] In some embodiments, the trailer basket is installed at the rear of the vehicle, i.e., the trailer basket is installed at the rear of the vehicle. Specifically, the trailer basket can be installed on the trailer square tube at the rear of the vehicle, or it can be installed on a modified rear bumper that has a trailer square tube. Regarding the connection method between the trailer basket and the trailer square tube, a detachable connection can be achieved by inserting the trailer basket into the trailer square tube and using bolts, screws, or other structural connections. This is existing technology and will not be described in detail in this embodiment.

[0034] like Figures 1-6 As shown, in this embodiment, the trailer basket includes a basket 1, a support mechanism 2, and a mounting mechanism 3. The basket 1 is used to carry items. The mounting mechanism 3 is installed at the rear of the vehicle. The support mechanism 2 includes a linkage bracket 21 and a position holding assembly 22. One side of the linkage bracket 21 is connected to the basket 1, and the other side is connected to the mounting mechanism 3. The height of one side of the linkage bracket 21 relative to the mounting mechanism 3 is adjustable. The position holding assembly 22 can maintain the height of one side of the linkage bracket 21 relative to the mounting mechanism 3.

[0035] Understandably, with the above configuration, one side of the connecting rod bracket 21 is connected to the basket 1, and the other side is connected to the mounting mechanism 3. The height of one side of the connecting rod bracket 21 relative to the mounting mechanism 3 is adjustable. When it is necessary to adjust the height of the basket 1, the height of one side of the connecting rod bracket 21 relative to the mounting mechanism 3 can be adjusted through the connecting rod bracket 21, thereby adjusting the height of the basket 1 relative to the mounting mechanism 3. After adjusting the height of the basket 1, the height of one side of the connecting rod bracket 21 relative to the mounting mechanism 3 can be maintained by the position holding component 22, thereby maintaining the height of the basket 1 relative to the mounting mechanism 3, improving the stability of the basket 1, and allowing users to flexibly adjust the load-bearing height of the basket 1 according to actual needs. Users do not need to frequently bend over or lift heavy objects during operation, thereby reducing the labor intensity of loading and unloading, and making operation easier and improving the user experience.

[0036] For example, such as Figure 3 As shown, the linkage bracket 21 includes a first linkage 211, a second linkage 212, and a third linkage 213. The second linkage 212 is arranged parallel to the mounting mechanism 3. One end of the first linkage 211 is hinged to one end of the second linkage 212, and the other end is hinged to the mounting mechanism 3. The second linkage 212 is connected to the basket 1. One end of the third linkage 213 is hinged to the middle of the second linkage 212, and the other end is hinged to the mounting mechanism 3. The position holding component 22 can maintain the angle between the first linkage 211 and the mounting mechanism 3 and the angle between the third linkage 213 and the mounting mechanism 3, so as to maintain the second linkage 212 at the height of the mounting mechanism 3. It is understandable that by setting up a first connecting rod 211, a second connecting rod 212, and a third connecting rod 213 that are hinged in sequence, and with the other ends of the first connecting rod 211 and the third connecting rod 213 both hinged to the mounting mechanism 3, the second connecting rod 212 can rise or fall when the first connecting rod 211 rotates, the third connecting rod 213 rotates, or the second connecting rod 212 moves. Since the second connecting rod 212 is connected to the basket 1, it can realize the rise or fall of the basket 1. Furthermore, the second connecting rod 212 is set parallel to the mounting mechanism 3, which can keep the basket 1 in a parallel state with the mounting mechanism 3 during the rise or fall of the basket 1, thus ensuring the stability of the basket 1 carrying the items.

[0037] Of course, in other embodiments, one end of the third link 213 can also be hinged to the other end of the second link 212. The hinge point between one end of the third link 213 and the second link 212 can be determined according to actual usage requirements, as long as the movement requirements of the link bracket 21 are met.

[0038] In this embodiment, when the vehicle is traveling on a level road, the mounting mechanism 3 is in a horizontal state, and the basket 1, which is parallel to the mounting mechanism 3, is also in a horizontal state, which can ensure the stability of the basket 1 carrying the goods. That is, no matter how the height of the basket 1 is adjusted, the second link 212 always remains parallel to the mounting mechanism 3. When the vehicle is traveling on a flat road, the basket 1 can be in a horizontal state or close to a horizontal state, which improves the stability of the basket 1 carrying the goods.

[0039] Specifically, the hinges between the first link 211, the second link 212, the third link 213, and the mounting mechanism 3 are all achieved by hinge shafts. Since the use of hinge shafts to achieve hinges is existing technology, this embodiment will not elaborate further.

[0040] In this embodiment, during the process of adjusting the overall height of the linkage bracket 21, the linkage bracket 21 is in a rotating state. When the linkage bracket 21 is at its lowest position, that is, when the basket 1 is at its lowest position, the basket 1 is furthest from the trailer square tube. When the vehicle bed is opened, the linkage bracket 21 can be positioned at its lowest position to reduce the risk of interference between the vehicle bed and the basket 1 and the support mechanism 2.

[0041] In some embodiments, such as Figures 3-4 As shown, notches are provided at both ends of the first link 211 and the third link 213, which facilitates the simultaneous hinge connection of the first link 211 and the third link 213 with the second link 212 and the mounting mechanism 3, and facilitates the rotation of the first link 211 and the third link 213, thus avoiding interference with the second link 212 and the mounting mechanism 3 when the first link 211 and the third link 213 rotate.

[0042] Furthermore, the first link 211 and the third link 213 are arranged in parallel, enabling the first link 211, the second link 212, the third link 213 and the mounting mechanism 3 to form a four-bar articulated structure with each pair of links parallel to each other. The mounting mechanism 3 is installed at the rear of the vehicle and is in a relatively stationary state relative to the vehicle. When adjusting the height of the basket 1, the height of the second link 212 can be adjusted by directly driving the first link 211, the second link 212 or the third link 213, thereby adjusting the load-bearing height of the basket 1.

[0043] Of course, in other embodiments, the linkage bracket 21 can also be directly configured as a four-bar structure. For example, the linkage bracket 21 includes a first link 211, a second link 212, a third link 213 and a fourth link. The fourth link is connected to the mounting mechanism 3, the second link 212 is connected to the basket 1, one end of the first link 211 is hinged to one end of the second link 212 and the other end is hinged to one end of the fourth link, one end of the third link 213 is hinged to the middle of the second link 212 and the other end is hinged to the other end of the fourth link, which facilitates the direct assembly of the linkage bracket 21.

[0044] In this embodiment, the position holding assembly 22 includes an adjustable damping element 221. One end of the adjustable damping element 221 is hinged to the first connecting rod 211, and the other end is hinged to the mounting mechanism 3. The adjustable damping element 221 can provide an adjustable damping force to the first connecting rod 211. When the first connecting rod 211 rotates around the rotation point, the adjustable damping element 221 can provide a damping force lower than a first preset value to the first connecting rod 211. When maintaining the angle between the first connecting rod 211 and the mounting mechanism 3, the adjustable damping element 221 can provide a damping force higher than a second preset value to the first connecting rod 211. It can be understood that by setting the adjustable damping element 221, the damping force output by the adjustable damping element 221 is adjustable, which facilitates the adjustment and fixing of the angle of the first connecting rod 211, thereby realizing the movement of the entire connecting rod bracket 21, so as to realize the height adjustment and height maintenance of the basket 1.

[0045] It should be noted that the adjustable damping element 221 can be an existing adjustable damper spring. The first preset value refers to the value of the force that drives the linkage bracket 21 to move, and the second preset value refers to the value of the force applied to the first linkage 211 when the basket 1 carries the maximum weight of the item that can be carried. The first and second preset values ​​can be determined according to the actual situation. The range of the output damping force of the adjustable damping element 221 can be determined according to the first and second preset values, as long as it meets the usage requirements.

[0046] It is understandable that, since the first link 211 and the third link 213 are arranged in parallel, and the second link 212 is arranged in parallel with the mounting mechanism 3, and the mounting mechanism 3 is in a fixed state, as long as the first link 211, the second link 212, or the third link 213 is in a fixed state, the link bracket 21 is in a fixed state, which can maintain the angle between the first link 211 and the mounting mechanism 3 and the angle between the third link 213 and the mounting mechanism 3, so as to maintain the height of the second link 212 relative to the mounting mechanism 3. Regarding the driving method of the link bracket 21, the operator can drive it manually or use existing driving components such as telescopic cylinders to drive it. This is not the focus of protection in this embodiment, and this embodiment does not make specific limitations.

[0047] Regarding the adjustment of the output damping force of the adjustable damping element 221, in this embodiment, as follows: Figure 2 As shown, the position holding assembly 22 also includes a damping adjustment switch 222. The damping adjustment switch 222 is used to adjust the damping force output by the adjustable damper 221. The damping adjustment switch 222 includes an operating handle and a pull rope. One end of the pull rope is connected to the operating handle, and the other end is connected to one end of the adjustable damper 221. Driving the operating handle can adjust the damping force provided by the adjustable damper 221 to the first link 211.

[0048] Specifically, the other end of the pull rope is connected to the actuator of the adjustable damping element 221, and the actuator is connected to the valve core inside the adjustable damping element 221. It can be understood that driving the operating handle can move the pull rope, the other end of which is connected to the actuator and can move the actuator to drive the valve core, changing the size of the damping orifice, thereby adjusting the damping force output by the adjustable damping element 221. After adjustment, releasing the operating handle causes the return spring of the adjustable damping element 221 to push the valve core back to its original position.

[0049] Furthermore, the operating handle is rotatably mounted on the linkage bracket 21. Specifically, the operating handle is rotatably mounted on the second linkage 212 to facilitate driving the pull rope.

[0050] It should also be noted that the actuator can be an adjusting fork or lever. A smaller damping orifice increases flow resistance and strengthens the damping force. Conversely, a larger damping orifice decreases flow resistance and weakens the damping force. The specific adjustment principle of the adjustable damper spring is existing technology and will not be elaborated upon in this embodiment.

[0051] To further improve the stability of the link bracket 21 and thus enhance the support stability of the basket 1, in some embodiments, the position holding assembly 22 further includes a locking member 223. A fixing hole group is provided on the side of the third link 213 away from the second link 212. The locking member 223 can pass through the fixing hole group and abut against the mounting mechanism 3 to fix the angle between the third link 213 and the mounting mechanism 3. Understandably, after adjusting the angle between the first link 211 and the mounting mechanism 3, and the angle between the third link 213 and the mounting mechanism 3, the adjustable damping element 221 applies a damping force to the first link 211 to prevent it from rotating. At this time, the angle between the first link 211 and the mounting mechanism 3, and the angle between the third link 213 and the mounting mechanism 3, are fixed. Then, the locking element 223 passes through the fixing hole group and abuts against the mounting mechanism 3, that is, the distance between the fixing hole group and the mounting mechanism 3 is fixed, and the third link 213 cannot rotate. This further fixes the angle between the third link 213 and the mounting mechanism 3, and further improves the stability of the link bracket 21.

[0052] Specifically, the locking element 223 includes a locking block 2231 and a locking pin 2232. The fixing hole group includes two coaxially arranged fixing holes. The locking block 2231 is installed between the two fixing holes. The locking pin 2232 can be sequentially inserted into one fixing hole, the locking block 2231, and the other fixing hole to press the locking block 2231 against the mounting mechanism 3. It can be understood that by sequentially inserting the locking pin 2232 into one fixing hole, the locking block 2231, and the other fixing hole, the locking block 2231 can be pressed against the mounting mechanism 3, that is, the distance between any fixing hole and the mounting mechanism 3 is fixed, so that the third link 213 cannot rotate.

[0053] In this embodiment, the locking component 223 includes multiple locking blocks 2231 with different heights, but all of them can be installed between two fixing holes. The locking pin 2232 can pass through the middle of the locking block 2231. When the basket 1 needs to be adjusted to different heights, the tilt angle of the third link 213 relative to the mounting mechanism 3 is different, and the distance between the middle of the locking block 2231 and the mounting mechanism 3 is different. By setting multiple locking blocks 2231 with different heights, it can adapt to the fixing of the third link 213 at different angles when the basket 1 needs to be adjusted to different heights, and has strong adaptability.

[0054] In some embodiments, the locking member 223 further includes an anti-detachment pin 2233. The locking pin 2232 includes a bent section 22321, an intermediate section 22322, and an anti-detachment section 22323 connected in sequence. When the locking pin 2232 passes through one of the fixing holes, the locking block 2231, and the other fixing hole, the bent section 22321 and the anti-detachment section 22323 are located on both sides of the third connecting rod 213, respectively. An anti-detachment hole is provided on the anti-detachment section 22323, and the anti-detachment pin 2233 passes through the anti-detachment hole. Understandably, the middle section 22322 is used to pass through one of the fixing holes, the locking block 2231, and the other fixing hole. The bent section 22321 can use its own structure to abut against the side of the third link 213 and will not pass through the fixing hole. The anti-detachment section 22323 has an anti-detachment hole, and the anti-detachment pin 2233 is inserted in the anti-detachment hole to prevent the anti-detachment section 22323 from passing through the fixing hole, so as to ensure that the locking pin 2232 will not fall off and ensure the fixing effect of the locking block 2231.

[0055] Specifically, the bending section 22321, the intermediate section 22322, and the anti-detachment section 22323 have the same diameter, and their diameters are all slightly smaller than the diameter of the fixing hole. The included angle between the bending section 22321 and the intermediate section 22322 prevents the intermediate section 22322 and the bending section 22321 from passing through the fixing hole in sequence. Of course, in other embodiments, the bending section 22321 can be omitted, and a limiting section with a diameter larger than the diameter of the fixing hole can be directly used to limit the locking pin 2232.

[0056] In this implementation, such as Figures 3-5 As shown, the installation mechanism 3 includes an installation tube 31, an abutment component 32, and a connector 33. The installation tube 31 can be inserted into the trailer square tube. The installation tube 31 has two mounting holes that are arranged opposite each other. The abutment component 32 passes through a preset side wall of the installation tube 31 and its position relative to the preset side wall is adjustable. The axial direction of the mounting hole is parallel to the preset side wall. When the installation tube 31 is inserted into the trailer square tube, the abutment component 32 can abut against the inner wall of the trailer square tube. The axis of the installation tube 31 is parallel to the axis of the trailer square tube. The connector 33 can pass through one through hole, two mounting holes, and another through hole.

[0057] Understandably, even when the mounting mechanism 3 is installed on trailer square tubes of different sizes, when the mounting tube 31 is inserted into the trailer square tube, the abutment component 32 can abut against the inner wall of the trailer square tube, making the axis of the mounting tube 31 parallel to the axis of the trailer square tube. The side wall of the mounting tube 31 opposite to the preset side wall can abut against the inner wall of the trailer tube. That is, the abutment component 32 passing through the preset side wall and the side wall opposite to the preset side wall abut against the two opposite inner walls of the trailer square tube respectively. The axis of the mounting hole is parallel to the preset side wall, that is, the abutment component 32 is perpendicular to the axis of the mounting hole. This can prevent the mounting tube 31 from rotating relative to the trailer square tube around the axis of the connector 33, avoid generating obvious impact noise, ensure driving comfort, and avoid the problems in the prior art where the connecting pipe is prone to bending deformation, wear and dent due to long-term reciprocating impact, and irreversible indentation and wear on the inner wall of the trailer square tube. This ensures the overall load-bearing capacity and service life of the mounting mechanism 3.

[0058] It should be noted that the two through holes of the trailer square tube are usually respectively set on the two horizontally upward side walls. The connector 33 can pass through one of the through holes, two mounting holes and the other through hole, and the abutment component 32 is perpendicular to the axial direction of the mounting hole. That is, the two mounting holes are also respectively set on the two horizontally upward side walls of the mounting tube 31. The preset side wall and the side wall opposite to the preset side wall are arranged opposite each other in the vertical direction. That is, the preset side wall can be the top wall or the bottom wall of the mounting tube 31. In this embodiment, the preset side wall is the top wall of the mounting tube 31.

[0059] In some embodiments, the mounting mechanism 3 further includes an adjusting component 34, which is located inside the mounting tube 31 and abuts against the abutment component 32. A connecting member 33 can pass through the adjusting component 34. Rotation of the connecting member 33 can drive the adjusting component 34 to move, thereby causing the abutment component 32 to abut against or move away from the inner wall of the trailer square tube. It can be understood that by providing the adjusting component 34, rotation of the connecting member 33 can drive the adjusting component 34 to move, thereby causing the abutment component 32 to abut against or move away from the inner wall of the trailer square tube, thereby achieving abutment between the abutment component 32 and the trailer square tube, ensuring the stability of the mounting tube 31, or the abutment component 32 no longer abuts against the inner wall of the trailer square tube, allowing for disassembly of the mounting tube 31 and the trailer square tube.

[0060] Specifically, during installation, rotating the connector 33 clockwise rotates the adjusting component 34, which in turn moves the abutment component 32 against the inner wall of the trailer square tube. During disassembly, rotating the connector 33 counterclockwise rotates the adjusting component 34, which moves the abutment component 32 away from the inner wall of the trailer square tube, thus preventing interference between the abutment component 32 and the inner wall of the trailer square tube.

[0061] For example, such as Figure 6 As shown, the adjusting component 34 includes a first wedge block 341 and a second wedge block 342. The first wedge block 341 is located between the second wedge block 342 and the abutment component 32. The first wedge block 341 has a first inclined surface, and the second wedge block 342 has a second inclined surface that cooperates with the first inclined surface. The connecting member 33 can pass through the second wedge block 342. Rotation of the connecting member 33 can drive the second wedge block 342 to move axially along the connecting member 33, so as to drive the abutment component 32 to abut against or move away from the inner wall of the trailer square tube. It can be understood that rotation of the connecting member 33 can drive the second wedge block 342 to move axially along the connecting member 33. Due to the inclined surface cooperation of the first wedge block 341 and the second wedge block 342, during the axial movement of the second wedge block 342 along the connecting member 33, the first wedge block 341 can be driven to rise or fall, so as to drive the abutment component 32 to abut against or move away from the inner wall of the trailer square tube.

[0062] Specifically, in this embodiment, taking the movement of the connector 33 from left to right during installation as an example, when the connector 33 passes through the second wedge block 342 from left to right, the second wedge block 342 moves to the left, and during the movement, the second wedge block 342 gradually rises. During disassembly, when the connector 33 moves from right to left, during the rotation of the connector 33, the second wedge block 342 moves to the right, and during the movement, the second wedge block 342 gradually descends.

[0063] Specifically, a first limiting groove is provided in the preset side wall, and multiple receiving holes are opened on the preset side wall. The multiple receiving holes are spaced apart along the length direction of the mounting tube 31, and all multiple receiving holes are connected to the limiting groove. The first wedge block 341 is partially located in the first limiting groove, and multiple abutment posts 321 are respectively inserted into the multiple receiving holes. It can be understood that by providing multiple receiving holes and having multiple abutment posts 321 respectively inserted into the multiple receiving holes, the movement of the multiple abutment posts 321 can be limited. The first wedge block 341 is always located in the first limiting groove, which can prevent the first wedge block 341 from dislodging from the first limiting groove during movement and prevent the first wedge block 341 from being misaligned.

[0064] In some embodiments, the adjusting component 34 further includes a third wedge 343, with the second wedge 342 located between the first wedge 341 and the third wedge 343. The second wedge 342 also has a third inclined surface, and the third wedge 343 has a fourth inclined surface that cooperates with the third inclined surface. It is understood that the cooperation between the third wedge 343 and the inclined surface of the second wedge 342 guides the movement of the second wedge 342, improving the smoothness of the movement of the second wedge 342.

[0065] Specifically, the third wedge block 343 has a limiting part 3431, and a second limiting groove is provided on one side wall opposite to the preset side wall. The limiting part 3431 passes through the second limiting groove to improve the stability of the third wedge block 343, avoid large displacement between the third wedge block 343 and the mounting tube 31, avoid misalignment, and ensure the stability of guiding the second wedge block 342.

[0066] For example, the abutment component 32 includes a plurality of abutment posts 321, each of which passes through a preset sidewall and abuts against the side of the first wedge block 341 away from the second wedge block 342. It is understood that by providing multiple abutment posts 321, the stability of the entire abutment component 32 can be improved by having multiple abutment posts 321 simultaneously abut against the inner wall of the trailer square tube. This avoids the situation where only one abutment post 321 is provided, which would result in excessive pressure between the abutment post 321 and the inner wall of the trailer square tube, thus damaging the quality of the inner wall surface of the trailer square tube or the end face quality of the abutment post 321.

[0067] In this embodiment, the connector 33 has a threaded section 331 and the second wedge block 342 has a threaded hole. The threaded section 331 is threadedly engaged with the threaded hole, thereby driving the second wedge block 342 to move along the axial direction of the connector 33 when the connector 33 is rotated.

[0068] In some embodiments, the mounting mechanism 3 further includes a limiting member 35, and the connector 33 includes a cap 332 and a rod connected together. A limiting hole is formed on the side of the rod away from the cap 332, and the limiting member 35 passes through the limiting hole. A threaded section 331 is formed on the side of the rod away from the limiting hole. Specifically, the cap 332 can abut against the trailer square tube. It is understood that by forming a limiting hole on the side of the rod away from the cap 332, and with the limiting member 35 passing through the limiting hole, the rod cannot pass through the through hole, and the cap 332 can prevent the connector 33 from falling off, ensuring the stability of the connection.

[0069] In this embodiment, as Figure 5 As shown, the trailer basket also includes a protective plate 4, which is installed on the mounting mechanism 3 and located on the side of the mounting mechanism 3 away from the basket 1. It can be understood that by providing the protective plate 4 on the side of the mounting mechanism 3 away from the basket 1, when driving on the road, it can prevent sewage and mud from adhering to the hinge points between the first link 211 and the third link 213 and the mounting mechanism 3, thus avoiding affecting the normal rotation of the first link 211 and the third link 213.

[0070] In this embodiment, the protective plate 4 is installed on the side wall of the mounting tube 31. Specifically, the protective plate 4 includes a plate body 43 and a first connecting plate 41 and a second connecting plate 42 located on top of the plate body 43 and arranged opposite to each other. The first connecting plate 41 has two first connecting holes, and the second connecting plate 42 has two second connecting holes. The two first connecting holes and the two second connecting holes correspond one-to-one. The hinge shaft on the first connecting rod 211 can pass through one of the first connecting holes and the second connecting hole corresponding to one of the first connecting holes. The hinge shaft on the third connecting rod 213 can pass through the other first connecting hole and the second connecting hole corresponding to the other first connecting hole. It can be understood that the installation of the protective plate 4 is achieved by using the hinge shafts used by the first connecting rod 211 and the third connecting rod 213, eliminating the need for additional mounting parts to fix the protective plate 4, thus saving costs. Furthermore, the first connecting holes and the second connecting holes are respectively opened on the first connecting plate 41 and the second connecting plate 42, avoiding the need to open holes on the plate body 43 and ensuring the protective effect.

[0071] In some embodiments, the plate 43 includes a horizontal portion 431 and an inclined portion 432 connected to each other. The horizontal portion 431 is located at the bottom of the mounting mechanism 3. In the length direction of the mounting mechanism 3, the inclined portion 432 is located at the end of the mounting mechanism 3 away from itself and connected to the trailer square tube, which further prevents sewage and dirt on the road surface from adhering to the hinge joint between the first link 211 and the third link 213 and the mounting mechanism 3, thereby improving the protective effect of the protective plate 4.
