[0020] Compared to the prior art, the present invention provides a curtain tensioning system for a side curtain vehicle. The vehicle side frame is rectangular in shape, and the top of the side curtain body is movably connected to the inner side of the top of the vehicle side frame. This movably connected system can be implemented by providing a groove with an inverted T-shaped longitudinal section at the bottom of the vehicle side frame, multiple inverted T-shaped slides at the top of the side curtain body, and pulleys on either side of the slides, which are slidably connected to the groove. Alternatively, the system can be implemented by providing a slide rail with an inverted Ω-shaped longitudinal section at the bottom of the vehicle side frame, multiple slides at intervals at the top of the side curtain body that movably engage the slide rails. Alternatively, the system can be implemented by providing a slide rod at the bottom of the vehicle side frame, multiple sliding rings at the top of the side curtain body, all of which movably engage the slide rod. The top of the side curtain body is connected to the inner side of the vehicle side frame, and an extended brim can be provided at the top of the vehicle side frame, depending on the actual situation. These systems can effectively prevent rainwater from entering the vehicle compartment.

[0021] When securing the side curtain bodies, after the side curtain bodies are properly positioned, the latching members are rotated upward one by one. During this upward rotation, the free ends of the rotating members swing downward. When the free ends of the rotating members contact the top of the outer end of the locking tongue, the locking tongue is driven into the telescopic slot until the first retaining groove of the latching member and the vehicle side frame secure the first anti-slip body. Alternatively, only the first anti-slip body can be secured, or the side curtain bodies can be wrapped around the outside of the first anti-slip body, and the first anti-slip body and the surrounding side curtain bodies are secured together. As the first anti-slip body is secured, the rotating member passes over the locking tongue. At this point, the elastic force of the first elastic member causes the locking tongue to move outward, and the bottom of the locking tongue is brought into contact with the top of the rotating member. In actual operation, an L-shaped rotating arm can be welded to the outside of the latching member. When rotating the rotating member, a worker can use a steel pipe or other structure to fit over the rotating arm, thereby easily rotating the latching member. At the same time, since the side curtain body has a certain flexibility, after the first anti-slip body is actually clamped, the buckle part can continue to rotate inwardly by a very small angle, so that the top of the rotating part is slightly lower than the bottom of the locking tongue (only a very small gap is needed), and then the locking tongue can be easily moved outward; even if the buckle part is loosened and the buckle part moves outward, the moving distance is very small, which can effectively prevent the first anti-slip body from detaching.

[0022] When opening the side curtain, simply horizontally move the synchronizing element so that all locking tongues move to the sides of their corresponding rotating parts. Gravity then causes the rotating parts and the fastening parts to rotate, automatically separating the fastening parts from the first anti-slip body. Once the fastening parts are separated from the first anti-slip body, the synchronizing element can be reset and the curtain can be used again.

[0023] During the entire process, only when fixing the bottom of the side curtain body do you need to operate the buckle parts one by one, and when loosening the side curtain body, all the buckle parts can be separated from the first anti-detachment body at one time, which makes the operation more convenient and efficient.

[0037] A vehicle side frame 1 and a side curtain body 2 movably connected to the inner side of the top of the vehicle side frame 1. A long first anti-slip body 3 (preferably a rope) is fixedly provided horizontally at the bottom of the side curtain body 2. The diameter of the first anti-slip body 3 is greater than the thickness of the side curtain body 2.

[0038] A bottom plate 4 is provided at the bottom of the vehicle side frame 1 and has a plurality of movable openings 5 ​​formed thereon. A support seat 6 is provided on the inner side of each movable opening 5.

[0039] A rotating portion 7, wherein the middle portion of the rotating portion 7 is vertically hinged to the support seat 6, and a buckle portion 8 perpendicular to the rotating portion 7 is provided on the outer side of the rotating portion 7, and a first limiting groove 9 is horizontally opened on the side of the buckle portion 8 close to the rotating portion 7;

[0040] When the top of the rotating part 7 contacts the bottom of the locking tongue 12, the first limiting groove 9 and the outer side of the vehicle side frame 1 clamp the first anti-separation body 3. When the locking tongue 12 and the rotating part 7 are misaligned, the buckling part 8 is separated from the first anti-separation body 3. When the free end of the rotating part 7 is located above the outer end of the locking tongue 12, the buckling part 8 is rotated upward to make the free end of the rotating part 7 act on the outer end of the locking tongue 12, thereby driving the locking tongue 12 to move into the telescopic groove.

[0044] Several long, strip-shaped openings 16 are vertically formed through the synchronizer 10. An anti-slip seat 17 is vertically provided at the bottom of the vehicle side frame 1. The anti-slip seat 17 passes through the opening 16. A second drag-reducing wheel 18 is rotatably provided on the side of the anti-slip seat 17. The second drag-reducing wheel 18 movably contacts the bottom of the synchronizer 10, and both sides of the anti-slip seat 17 movably fit against the inner walls of the opening 16. The second drag-reducing wheel 18 and the first drag-reducing wheel can reduce the movement resistance of the synchronizer 10, while the anti-slip seat 17 can improve the movement stability of the synchronizer 10.

[0045] A power column 19 is provided at the bottom of the vehicle side frame 1 for horizontal rotation. A fixing mechanism for fixing the angle of the power column 19 is provided on the vehicle side frame 1. A power disc 20 is provided on the power column 19. A plurality of power teeth 21 are provided at the bottom of the power disc 20. An L-shaped linkage part 22 is provided at the end of the synchronizer 10. The top of the vertical part of the linkage part 22 is connected to the synchronizer 10, and the top of the horizontal part is engaged with the power teeth 21. The side of the power disc 20 is provided with a rotating handle for rotating the power disc 20.

[0046] Two tensioning discs 23 are arranged at intervals on the outer wall of the power column 19, and a plurality of C-shaped anti-slip teeth 24 are arranged at intervals on the outer wall of the tensioning disc 23. The length of the first anti-slip body 3 is greater than the length of the side curtain body 2, and the end of the first anti-slip body 3 is located outside the side curtain body 2. The free end of the first anti-slip body 3 is provided with an I-shaped anti-slip piece 25. The end of the anti-slip piece 25 connected to the first anti-slip body 3 can be engaged with any pair of opposite anti-slip teeth 24, and the end of the first anti-slip body 3 is located between the two tensioning discs 23. When the outer end of the anti-slip piece 25 is pulled, the skin of the finger can be prevented from being pinched by the anti-slip teeth 24, thereby improving the safety of operation.

[0047] The end of the side curtain away from the power column 19 is fixedly connected to the vehicle side frame 1, and the end close to the power column 19 is vertically provided with a second anti-slip body 26 (preferably a rope). The diameter of the second anti-slip body 26 is greater than the thickness of the side curtain body 2;

[0048] A fan-shaped bevel gear body 27 is provided on the top of the power disk 20, and two side seats 28 are provided on the outer side of the vehicle side frame 1. A side rod 29 is provided vertically through the two side seats 28 and is rotatably connected to the side seats 28. A passive bevel gear 30 meshing with the bevel gear body 27 is horizontally provided at the bottom of the side rod 29. The passive bevel gear 30 is located on the outer side of the bevel gear body 27. A clamping portion 31 is provided on the side rod 29. A second limiting groove 32 is vertically opened on the side of the clamping portion 31. When the first limiting groove 9 limits the first anti-detachment body 3, the second limiting groove 32 and the outer side of the vehicle side frame 1 clamp and limit the second anti-detachment body 26.

[0049] The vehicle side frame 1 is provided with a first matching groove and a second matching groove. A first anti-slipping space for limiting the first anti-slipping body 3 is formed between the first matching groove and the first limiting groove 9. A second anti-slipping space for limiting the second anti-slipping body 26 is formed between the second matching groove and the second limiting groove 32. The free end of the buckle portion 8 and the free end of the pressing portion 31 both press the side curtain body 2 to fit against the outer side of the vehicle side frame 1.

[0050] The fixing mechanism includes a fixing bracket 33 arranged on the outside of the vehicle side frame 1, and a movable hole with a rectangular longitudinal section is opened horizontally through the fixing bracket 33, and a fixing rod is provided through the movable hole horizontally and movably, and the outer wall of the fixing rod is movably fitted into the inner wall of the movable hole, and the outer end of the fixing rod is provided with an operating disk 34, and the inner end is provided with an outer wall disk 35, and a second elastic member 36 that is continuously in a compressed state is provided between the outer side of the outer wall disk 35 and the inner side of the fixing bracket 33, and a positioning column is provided on the inner side of the outer wall disk 35, and a synchronous disk 37 is fixedly provided at the inner end of the power column 19, and a plurality of fixing holes 38 are opened on the side wall of the synchronous disk 37, and the end of the positioning column can be inserted into any of the fixing holes 38, and a first hole body is opened vertically through the fixing bracket 33, and a second hole body is opened vertically through the fixing rod. When the positioning column is inserted into one of the fixing holes 38, the first hole body is communicated with the second hole body.

[0051] The present invention provides a curtain tensioning system for a side curtain vehicle. The side frame 1 is a rectangular vehicle side frame. The top of the side curtain body 2 is movably connected to the inner side of the top of the side frame 1. This movably connected system can be implemented by providing a groove with an inverted T-shaped longitudinal section at the bottom of the side frame 1, with multiple inverted T-shaped slides at the top of the side curtain body 2, and pulleys on either side of the slides, which are slidably connected to the groove. Alternatively, the system can be implemented by providing a slide rail with an inverted Ω-shaped longitudinal section at the bottom of the side frame 1, with multiple slides at intervals at the top of the side curtain body 2 movably connected to the slide rails. Alternatively, the system can be implemented by providing a slide rod at the bottom of the side frame 1, with multiple sliding rings at the top of the side curtain body 2, all of which are movably connected to the slide rod. The top of the side curtain body 2 is connected to the inner side of the side frame 1. Alternatively, the top of the side frame 1 can be provided with an extended brim, which effectively prevents rainwater from entering the vehicle compartment.

[0052] When securing the side curtain body 2, after the side curtain body 2 reaches the proper position, the fastening portion 8 is rotated upward one by one. During this upward rotation, the free end of the rotating portion 7 swings downward. When the free end of the rotating portion 7 acts on the top of the outer end of the locking tongue 12, the locking tongue 12 is driven to move into the telescopic slot until the first limiting groove 9 of the fastening portion 8 and the vehicle side frame 1 secure the first anti-detachment body 3. This can either secure only the first anti-detachment body 3, or the side curtain body 2 can surround the outside of the first anti-detachment body 3, and then the first anti-detachment body 3 and the surrounding side curtain body 2 are secured together. As the first anti-detachment body 3 is secured, the rotating portion 7 just passes over the locking tongue 12. At this time, under the elastic force of the first elastic member 13, the locking tongue 12 moves outward, and the lower side of the locking tongue 12 is in contact with the top of the rotating portion 7. In actual operation, an L-shaped rotating arm can be welded to the outside of the buckle part 8. Then, when the worker rotates the rotating part 7, he can use a steel pipe or other structure to be connected to the rotating arm, so that the buckle part 8 can be easily rotated. At the same time, because the side curtain body 2 has a certain flexibility, after the first anti-separation body 3 is clamped, the buckle part 8 can be further rotated inward by a very small angle, so that the top of the rotating part 7 is slightly lower than the bottom of the locking tongue 12 (only a very small gap is required), which can then facilitate the outward movement of the locking tongue 12. Even if the buckle part 8 is loosened and the buckle part 8 moves outward, the movement distance is very small, which can effectively prevent the first anti-separation body 3 from detaching.

[0053] When opening the side curtain body 2, it is only necessary to horizontally adjust the synchronizing member 10 so that all the locking tongues 12 move to the side of the corresponding rotating portion 7. Then, the rotating portion 7 and the buckling portion 8 rotate under the action of gravity, and the buckling portion 8 automatically separates from the first anti-separation body 3. After the buckling portion 8 separates from the first anti-separation body 3, the synchronizing member 10 can be reset and the curtain can be used directly next time.

[0054] During the entire process, the buckle parts 8 need to be operated one by one only when fixing the bottom of the side curtain body 2. When loosening the side curtain body 2, all the buckle parts 8 can be separated from the first anti-separation body 3 at one time, which makes the operation more convenient and efficient.

[0055] When securing the side curtain body 2, the worker first needs to pull the anti-slip member 25 to flatten the side curtain body 2. At this time, since the end of the side curtain body 2 away from the power column 19 (preferably the end closer to the front of the vehicle) is fixedly connected to the vehicle side frame 1, it is only necessary to forcefully pull the anti-slip member 25 backward. Then, the end of the anti-slip member 25 connected to the first anti-slip body 3 is snapped into the two opposing anti-slip teeth 24 (the first anti-slip body 3 is now in a preliminarily tensioned state). The end of the first anti-slip body 3 is located between the two tensioning discs 23, preventing the anti-slip member 25 from detaching from the tensioning discs 23. The worker then turns the rotating handle downward (the rotating handle can be fixed to the outer wall of the power disc 20, or a telescopic handle available on the market, or a hole is opened on the side of the power disc 20, and the rotating handle can be inserted into the hole for rotation, and then pulled out of the hole for storage when not in use). At this time, the power gear body 21 at the bottom of the power disc 20 drives the synchronizer 10 to reset through the linkage part 22, and at the same time the bevel gear body 27 moves and drives the side rod 29 to rotate through the passive bevel gear 30, so that the pressing part 31 swings toward the second anti-slip body 26. When the tension of the first anti-slip body 3 reaches the appropriate level, the pressing part 31 also swings to the appropriate position, and the second anti-slip body 26 is clamped by the second limiting groove 32 and the second matching groove, and the free end of the pressing part 31 presses the side curtain body 2 against the outside of the vehicle side frame 1, thus fully ensuring the positional stability of the vertical part of the side curtain body 2.

[0056] Before turning the handle, the worker must pull the operating disc 34 outward with one hand to separate the positioning post from the fixing hole 38. Once the power disc 20 reaches the desired angle, the worker simply releases the operating disc 34. The elastic force of the second elastic member 36 allows the positioning post to be inserted into the corresponding fixing hole 38, thereby fixing the angles of the synchronizing disc 37, the power post 19, the power disc 20, and the tensioning disc 23. This also secures the positions of the pressing portion 31, the first anti-slip body 3, and the second anti-slip body 26. The first anti-slip body 3 can now be secured by simply rotating the fastening portion 8 upward. The first anti-slip body 3 is restrained by both the first mating groove and the first limiting groove 9, while the second anti-slip body 26 is restrained by both the second mating groove and the second limiting groove 32. This further ensures the stability of the horizontal free end and bottom of the side curtain body 2.

[0057] Moreover, since the positions of the first hole body and the second hole body are relative, a U-shaped lock or other lock can be passed through the first hole body and the second hole body at the same time, thereby further improving the positional stability of each structure.

[0058] When opening the side curtain body 2, first unlock the U-lock, then pull the operating disk 34 outward to disengage the positioning post from the fixing hole 38, and then turn the rotating handle upward. At this time, the power gear body 21 drives the synchronizer 10 to move through the linkage part 22, so that all the locking tongues 12 move to the side of the corresponding rotating part 7, so that all the buckling parts 8 are naturally opened. At the same time, the bevel gear body 27 drives the side rod 29 to rotate through the passive bevel gear 30, so that the pressing part 31 releases the second linkage part 22. In this way, the bottom and end of the side curtain body 2 can be loosened at the same time by simply turning the rotating handle, and then the side curtain body 2 can be directly opened.

[0059] That is, during the entire use process, only the buckle parts 8 need to be rotated one by one to fix the bottom of the side curtain body 2. When the power disk 20 is rotated, the first anti-slip body 3 and the second anti-slip body 26 can be tightened at the same time, and the second anti-slip body 26 can also be fixed. Then, when the first anti-slip body 3 and the second anti-slip body 26 are released, only the power disk 20 needs to be rotated, which is highly convenient to operate.

[0060] It should also be noted that all references to "disposed" and similar descriptors in this application (especially in this specification) express that two structures have or exist in a connection relationship. However, the specific means by which the two structures are connected are not particularly limited, and are generally conventional connection means. In other words, such means should be understood as existing in the art and do not require further elaboration. For example, "n is disposed on m" simply expresses that structure n is present on structure m, while the two are specifically connected by welding, riveting, adhesive bonding, or integral molding, all of which are within the scope of protection of this application. Another example is "y is rotatably disposed on x" simply expresses that y and x are rotatable relative to each other, while whether the two are connected by a bearing, y directly passes through x and is rotatably connected to x, or other feasible methods are all within the scope of protection of this application.

[0061] The above description is only a description of the preferred embodiments of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
