[0039] Embodiments of the present application are described below in the detailed description and illustrated in the accompanying drawings by various drawings for example. Identical or similar elements or elements having identical or similar functions are denoted throughout the same or similar reference numerals, based on the embodiments in the embodiments. It is intended to explain the present application based on the embodiments, and cannot be understood as a limitation of the present application.

[0040] In this specification, "one embodiment" or "an example" or "an example" means that the specific features, structures or characteristics described in connection with the embodiment itself can be included in at least one embodiment of the present disclosure. The occurrence of the phrase "in one embodiment" at various locations in the specification does not necessarily refer to the same embodiment.

[0041] A support device for vehicle transportation fixation in the related art, when the support force for the material needs to be removed and the telescopic pipe is pressed between the materials, in order to improve the efficiency, the limit of the telescopic pipe is generally removed, and the telescopic pipe is quickly retracted or quickly extended manually. The operation part of the driving assembly in the related art is in the position of removing the limit, and the space between the operation part and the telescopic pipe extension part is small. When the telescopic pipe is quickly extended or quickly retracted, the operator is easily injured.

[0042] As one of the embodiments of the present application, refer to the accompanying Figures 1 to 10 A support device for vehicle transportation fixation is disclosed, which comprises an outer sleeve 10, a telescopic pipe 20 and a telescopic driving assembly. The outer sleeve 10 is sleeved on the outside of the telescopic pipe 20, one end of the telescopic pipe 20 extends out of the outer sleeve 10, and the telescopic driving assembly is arranged on the outer sleeve 10 and used for driving the telescopic pipe 20 to extend out of the outer sleeve 10,

[0043] The telescopic driving assembly comprises a support 31, a retreat stopping unit 32 and a driving unit 33. The support 31 is connected with the outer sleeve 10, the driving unit 33 and the retreat stopping unit 32 are located on one side of the telescopic pipe 20 and are respectively pivotally connected with the support 31. The driving unit 33 comprises an operation part 331 and a matching part 332 connected with each other. The pivot axis of the driving unit 33 intersects with the axis of the telescopic pipe 20. The operation part 331 can drive the driving unit 33 to rotate and switch between a first position and a second position under the action of an external force.

[0044] In the first position, the matching part 332 and at least one of the retreat stopping unit 32 are clamped and matched with the telescopic pipe 20 to limit the telescopic pipe 20 from retracting into the outer sleeve 10.

[0045] In the second position, both the mating part 332 and the anti-reverse unit 32 are disengaged from the telescopic tube 20, and the axial directions of the operating part 331 and the portion of the telescopic tube 20 extending out of the outer sleeve 10 form a set angle.

[0046] In one embodiment of the present invention, the first position is located between the second position and the portion of the telescopic tube 20 extending out of the outer tube 10;

[0047] In the first position, when the drive unit 33 rotates toward the part of the telescopic tube 20 that extends out of the outer tube 10, the mating part 332 can engage with the telescopic tube 20 and drive the telescopic tube 20 to extend out of the outer tube 10.

[0048] When the drive unit 33 rotates toward the part of the telescopic tube 20 that extends out of the outer tube 10 away from the telescopic tube 20, the first end of the drive unit 33 can move in the opposite direction to the telescopic tube 20 in the direction of extension of the telescopic tube 20, and is limited to cooperate with the telescopic tube 20 to restrict the retraction of the telescopic tube 20 into the outer tube 10.

[0049] The cargo support device for vehicle transportation in this embodiment is generally used in transportation equipment (such as vans) in the logistics and transportation industry to support and fix materials. It can support materials horizontally or vertically. The following description uses the vertical support method as an example.

[0050] In this embodiment, a cargo support device for securing vehicles is typically equipped with support pads 50 at the end of the outer tube 10 furthest from the telescopic tube 20 and at the end of the telescopic tube 20 extending out of the outer tube 10, respectively. (See attached diagram.) Figure 1 , 6 8. When in use, the support pad 50 is in direct contact with the material to increase the support area. When setting it up, the support pad 50 can generally be made of rubber or plastic material to reduce damage to the material.

[0051] In this embodiment, the telescopic drive assembly is used to drive the telescopic tube 20 to extend out of the outer tube 10. The telescopic drive assembly is connected to the outer tube 10 via a support member 31. During installation, the support member 31 is generally configured to be detachably connected to the outer tube 10, as shown in the attached figure. Figure 8 As shown, the support member 31 in this embodiment is set as a clamp structure, which allows for the use of outer tubes 10 with different outer diameters within a certain range, thus improving the applicability.

[0052] In a vehicle transport securing device, when used vertically, during the intermittent period when the drive unit 33 pushes the telescopic tube 20 outward, if there is no corresponding anti-retraction structure, the telescopic tube 20 will fall into the outer sleeve 10 under its own weight. In this embodiment, the anti-retraction unit 32 is used to limit the retraction of the telescopic tube 20, ensuring that the extended position of the telescopic tube 20 is limited, thus preventing retraction and improving the efficiency of the extension. In this embodiment, the anti-retraction unit 32 directly engages with the telescopic tube 20 for limiting its position. Compared to related technologies that indirectly limit the position of the telescopic tube 20 by limiting the gear (drive component), this method is more effective in limiting the position of the telescopic tube 20 and improves its stability.

[0053] In this embodiment, the drive unit 33 can intermittently drive the extension action of the telescopic tube 20. At least one of the drive unit 33 and the anti-retraction unit 32 engages with the telescopic tube 20 during the extension process, which can prevent the telescopic tube 20 from retracting, ensure extension efficiency, and keep the telescopic tube 20 stably in the extended position.

[0054] In this embodiment, the drive unit 33 can drive the telescopic tube 20 to move in one direction. When setting it, it can be set as a structure with a pawl and a rack 22, or a structure with a telescopic pin and a rack 22, or other similar structures.

[0055] In this embodiment, the anti-reverse unit 32 can directly cooperate with the telescopic tube 20 to form a limiting and anti-reverse effect. Moreover, the drive unit 33 can also engage the telescopic tube 20 during the stationary process, which can also play an anti-reverse effect. Thus, a double limiting effect can be formed, which can effectively prevent the telescopic tube 20 from retracting and improve the stability of the operation of a cargo support device used for vehicle transportation and fixing.

[0056] It should be noted that this embodiment does not specifically limit how the anti-reverse unit 32 and the drive unit 33 engage with the telescopic tube 20. For example, teeth or locking holes can be provided on the telescopic tube 20.

[0057] In this embodiment, when the drive unit 33 is in the first position (a position within a certain area), the telescopic tube 20 can only extend and cannot retract into the outer tube 10. This is suitable when pressure needs to be applied after the support pad 50 at the extended end of the telescopic tube 20 contacts the material. The support force can be gradually increased by rotating the drive unit 33. In the second position, the drive unit 33 in this embodiment can not only disengage its own mating part 332 from the telescopic tube 20, but also drive the anti-retraction unit 32 to disengage from the telescopic tube 20. At this time, the retraction of the telescopic tube 20 is not restricted, and the telescopic tube 20 can freely extend and retract relative to the outer tube 10. At this time, the operator can quickly move the telescopic tube 20 to the predetermined position. For example, when the distance between the material to be supported and the support point is large, the drive unit 33 can be rotated to the second position, and the operator can manually pull the telescopic tube 20 outward, so that the support pad 50 at the outer end of the telescopic tube 20 quickly extends to the position in contact with the material. Then, the support force can be gradually applied by rotating the drive unit 33 in the first position.

[0058] See appendix Figure 4 In this embodiment, the operating part 331 in the second position is in a position that is approximately parallel to the telescopic tube 20. At this time, the space between the operating part 331 and the extended part of the telescopic tube 20 is the largest. When the operator extends or retracts the telescopic tube 20, he / she will not be squeezed by the operating part 331 and the extended part of the telescopic tube 20, which is safer.

[0059] In this embodiment, the setting angle is not specifically limited. In actual setting, the setting angle is generally between 120° and 180°.

[0060] In this embodiment, the specific structure for how the telescopic tube 20 engages with the drive unit 33 and the engaging unit is not limited. In practice, a rack 22 or a locking hole can be provided on the telescopic tube 20. The following description uses the telescopic tube 20, including the tube body 21 and the rack 22, as an example to illustrate the solution of this application.

[0061] In one embodiment of the present invention, the anti-reverse unit 32 includes a first anti-reverse member 321 and a first elastic member 322. The first anti-reverse member 321 is pivotally connected to the support member 31. The first anti-reverse member 321 includes an anti-reverse portion 3213 and a pressure-receiving portion 3212. The anti-reverse portion 3213 and the pressure-receiving portion 3212 are disposed on opposite sides of the pivot axis on which the anti-reverse unit 32 is pivotally connected to the support member 31. The anti-reverse portion 3213 is opposite to the telescopic tube 20 and is used to engage with the telescopic tube 20. The pressure-receiving portion 3212 is opposite to the operating portion 331. In the second position, the operating portion 331 can push the pressure-receiving portion 3212 to rotate, thereby causing the anti-reverse portion 3213 to disengage from the telescopic tube 20. The elastic member is disposed between the first anti-reverse member 321 and the support member 31 and is used to keep the anti-reverse portion 3213 engaged with the telescopic tube 20.

[0062] See appendix Figures 2 to 5 In this embodiment, the telescopic tube 20 and the anti-reverse unit 32 form a mutually engaging structure through the anti-reverse member 321 (see attached figure, one end of which is a ratchet structure) and the rack 22. The anti-reverse unit 32 provides a one-way limiting effect on the telescopic tube 20. The anti-reverse unit 32 includes a first elastic member 322. The first elastic member 322 can maintain the first end (ratchet end) of the anti-reverse member 321 in a state of mutual contact with the rack 22 through its own elasticity, thus ensuring the stability of the anti-reverse effect of the anti-reverse unit 32.

[0063] As one embodiment of the present invention, see Appendix Figure 7 The support member 31 has a first pivot hole 313, and the anti-retraction member 321 has a protruding first pivot shaft 3211. The first pivot shaft 3211 is inserted into the first pivot hole 313. The first pivot hole 313 includes a first limiting surface 3131 and a second limiting surface 3132 arranged circumferentially. The first pivot shaft 3211 is disposed between the first limiting surface 3131 and the second limiting surface 3132. When the ratchet end of the anti-retraction member 321 is engaged with the rack 22, the first pivot shaft 3211 is limited by the first limiting surface 3131. During the extension of the telescopic tube 20, the teeth of the rack 22 can push the anti-retraction member 321 to rotate, so that the anti-retraction member 321 and the telescopic tube 20 move relative to each other. The first elastic member 322 is used to provide the anti-retraction member 321 with a torque to reset it from the position after being pushed by the teeth to the position engaged with the teeth.

[0064] In this embodiment, the first limiting surface 3131 and the second limiting surface 3132 formed in the first pivot hole 313 restrict the rotation range of the anti-reverse member 321, so that the anti-reverse member 321 can only rotate within a certain range, reducing the possibility of jamming failure. In addition, since the anti-reverse unit 32 is subject to the gravity of the telescopic tube 20 and the reaction force of the pressure on the top of the cargo when it forms an anti-reverse limit on the telescopic tube 20, the anti-reverse member 321 can withstand greater pressure through the limiting effect of the first limiting surface 3131, thus improving the stability of the anti-reverse effect.

[0065] As one embodiment of the present invention, see Appendix Figure 9 , 10 The drive unit 33 includes an operating part 331, a mating part 332, and a second elastic member 333. The operating part 331 includes a first end and a second end opposite to each other. The operating part 331 is pivotally connected to the support member 31, and the pivotal connection is located between the first end and the second end of the operating part 331. It can rotate and switch between the first position and the second position. The mating part 332 is rotatably disposed at the first end of the operating part 331 and is opposite to the rack 22. The mating part 332 is rotatably connected to the first end of the operating part 331. The second elastic member 333 is disposed between the mating part 332 and the operating part 331 and is used to keep the ratchet end of the mating part 332 engaged with the rack 22 during the rotation of the operating part 331 in the first direction.

[0066] In this embodiment, the cargo support for vehicle transportation is used by the user to drive the extension of the telescopic tube 20 through the operating part 331. The pivot connection between the operating part 331 and the support member 31 is located between the first end and the second end of the operating part 331. In this way, the operating part 331 forms a lever-like structure. By designing the length of the lever arm, the extension of the telescopic tube 20 can be driven with less effort.

[0067] In this embodiment, the drive unit 33 also drives the extension of the telescopic tube 20 through a one-way engagement structure of the mating part 332 and the rack 22. Combined with the structure of the anti-retraction member 321 in the anti-retraction unit 32 mentioned above, a double ratchet structure is formed. During use, at least one of the anti-retraction member 321 and the mating part 332 will engage with the rack 22, so that the telescopic tube 20 can extend intermittently as the control handle is rotated.

[0068] The second elastic element 333 in this embodiment has a similar function to the first elastic element 322 mentioned above, which can improve the effectiveness and stability of the engagement between the mating part 332 and the rack 22.

[0069] In this embodiment, both the anti-reverse component 321 and the mating part 332 cooperate with the rack 22. In actual installation, the anti-reverse component 321 and the mating part 332 can be spaced apart along the axial direction of the telescopic tube 20, as shown in the attached figure. Figure 1 The mating part 332 is generally located on the top side of the anti-reverse member 321. This can avoid interference that may occur during the driving process and facilitate the setting of the mating part 332 to achieve a larger single driving stroke.

[0070] In this embodiment, the structure with double ratchet plates allows the mating part 332 to span multiple teeth at once during the extension of the telescopic tube 20, compared to the structure in related technologies that uses gears and telescopic tube 20 meshing. Compared to the gear structure that can only drive one tooth at a time, the double ratchet plate driving structure of this embodiment has a greater lifting capacity and improved efficiency.

[0071] As one embodiment of the present invention, referring to the accompanying drawings, a second pivot hole 334 is formed at the first end of the operating part 331, and a protruding second pivot shaft 3321 is formed on the mating part 332. The second pivot shaft 3321 is inserted into the second pivot hole 334. The second pivot hole 334 includes a third limiting surface 335 and a fourth limiting surface 336 arranged circumferentially. The second pivot shaft 3321 is disposed between the third limiting surface 335 and the fourth limiting surface 336. When the ratchet end of the mating part 332 is engaged with the rack 22, the outer surface of the second pivot shaft 3321 abuts against the third limiting surface 335.

[0072] In this embodiment, the third limiting surface 335 and the fourth limiting surface 336 can limit the rotation of the mating part 332. Moreover, through the limiting effect of the third limiting surface 335 and the mating part 332, the pressure that the mating part 332 can withstand can be increased, thereby better driving the extension of the telescopic tube 20.

[0073] As one embodiment of the present invention, see Appendix Figure 8 The cargo support for vehicle transport also includes a locking component 40, which is disposed between the operating part 331 and the support member 31 and is used to lock the operating part 331.

[0074] In this embodiment, the locking component 40 can limit the position of the operating part 331 after the telescopic tube 20 is adjusted to the correct position. After the locking component 40 locks the operating part 331, the operating part 331 cannot continue to rotate, that is, the operating part 331 cannot be moved at this time, and the telescopic tube 20 cannot continue to extend outward, which can avoid damage to the goods caused by excessive pressure due to excessive extension. In addition, after the operating part 331 is locked, the position of the mating part 332 is also fixed. The mating part 332 can also limit the telescopic tube 20. Combined with the anti-reverse effect of the anti-reverse part 321, a double limiting effect can be achieved, improving the stability of the position of the telescopic tube 20.

[0075] This embodiment does not specifically limit the structure of the locking component 40. In actual installation, it can be locked by screws, by a locking plate, or by other locking structures.

[0076] As one embodiment of the present invention, see Appendix Figure 2 , 8 9, 10, The locking assembly 40 includes a locking member 41 and a positioning plate 43. The positioning plate 43 is fixedly connected to the support member 31. A locking mounting hole 3311 is formed on the operating part 331. The locking member 41 passes through the locking mounting hole 3311 and is rotatably connected to the inner wall of the locking mounting hole 3311. One end of the locking member 41 is opposite to the positioning plate 43 and forms a locking groove 411. The locking member 41 is adapted to rotate and switch between a locked position and an unlocked position under the action of external force. In the locked position, the locking groove 411 engages with the positioning plate 43 to lock the operating part 331. In the unlocked position, the positioning plate 43 and the locking member 41 disengage from each other.

[0077] The locking assembly 40 further includes a locking elastic member 42. The locking mounting hole 3311 includes a first hole segment 3311a and a second hole segment 3311b. The width of the first hole segment 3311a is smaller than the width of the second hole segment 3311b. The connection between the first hole segment 3311a and the second hole segment 3311b forms a positioning step. The locking elastic member 42 is disposed between the locking member 41 and the operating part 331 and is used to keep the locking member 41 in the unlocked position. In the unlocked position, the locking member 41 abuts against the positioning step.

[0078] In this embodiment, the locking member 41 is installed on the operating part 331. The rotation of the operating part 331 is limited by the engagement of the locking member 41 with the positioning plate 43 (installed on the support member 31). By setting two hole segments of different widths in the locking mounting hole 3311 and the locking elastic member 42, the locking member 41 can be stably kept in the unlocked position and the locked position, and interference with the rotation of the operating part 331 that may occur during the driving process can be avoided.

[0079] As one embodiment of the present invention, see Appendix Figure 8 The support member 31 includes a sleeve portion 311 and two opposing flat plate portions 312.
