Branched band winding structure and automobile

Abstract

This invention provides a branch tape winding structure and an automobile. The branch tape winding structure includes a support frame, a reel, a branch tape, a coiling spring mechanism, and a locking mechanism. The reel is rotatably connected to the support frame. The first end of the branch tape is fixed to the reel, and the branch tape is wound around the reel. The coiling spring mechanism is connected to both the support frame and the reel, controlling the rotation of the reel to retract or unfold the branch tape. The locking mechanism is connected to both the support frame and the reel, allowing the reel to be in a locked or unlocked state. In this invention, when the branch tape unfolds, the coiling spring mechanism relaxes, and the reel rotates accordingly. Conversely, when the branch tape retracts, the coiling spring mechanism tightens, causing the reel to rotate in the opposite direction, thus rewinding the branch tape onto the reel. This facilitates the retraction or unfolding of the branch tape, avoids long-term exposure of the branch tape to the elements, increases the weather resistance and service life of the branch tape, prevents product corrosion and aging, and ensures high reliability.

[0050] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below 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 are not intended to limit the invention.

[0051] In the description of this invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, 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, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0052] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0053] This invention provides a branched band winding structure, referring to... Figure 1-2The branch belt winding structure includes a support frame 1, a roller 2, a branch belt 3, a coiling spring mechanism 4, and a locking mechanism 5. The roller 2 is rotatably connected to the support frame 1, and the branch belt 3 is wound around the roller 2. The coiling spring mechanism 4 is connected to both the support frame 1 and the roller 2, and controls the rotation of the roller 2 to retract or unfold the branch belt 3. The locking mechanism 5 is connected to both the support frame 1 and the roller 2 to allow the roller 2 to be in a locked or unlocked state.

[0054] As an example, a branch tape retractable structure is fixed to a car to shield tree branches and protect the windshield. In this example, support frame 1 is fixed to the car, and reel 2 is rotatably connected to support frame 1. A limiting groove is reserved on reel 2. The head of branch tape 3 (i.e., the first end of branch tape 3) is folded and sewn to a pin, and then the pin is installed into the limiting groove of reel 2 and fixed by bolts at both ends of the limiting groove. Branch tape 3 is wound around reel 2. Spring mechanism 4 is installed on the first side of support frame 1 and connected to the first end of reel 2. Spring mechanism 4 controls the rotation of reel 2 to retract or unfold branch tape 3. When the branch belt 3 unfolds, the coiling spring mechanism 4 relaxes, and the scroll 2 rotates simultaneously. Conversely, when the branch belt 3 retracts, the coiling spring mechanism 4 tightens, causing the scroll 2 to rotate in the opposite direction, thus rewinding the branch belt 3 onto the scroll 2. This facilitates the unfolding and retraction of the branch belt 3, preventing it from being exposed to the elements for extended periods, increasing its weather resistance and service life, preventing corrosion and aging, and ensuring high reliability. The locking mechanism 5 is installed on the second side of the support frame 1 and is connected to the second end of the scroll 2. It controls the scroll 2 to be in a locked or unlocked state. When the branch belt 3 is pulled outwards at excessive speed, the locking mechanism 5 is activated, locking the scroll 2 and preventing it from being pulled. When the locking mechanism 5 is not activated, the scroll 2 remains unlocked, allowing it to rotate normally and the branch belt 3 to be pulled.

[0055] In one embodiment, reference is made to Figure 2 The support frame 1 includes a main plate 11 and a first support plate 12 and a second support plate 13 extending from the two sides of the main plate 11 in the same direction; a first mounting position 14 is provided on the first support plate 12, and a coil spring mechanism 4 is mounted on the first mounting position 14; a second mounting position 15 is provided on the second support plate 13, and a locking mechanism 5 is mounted on the second mounting position 15.

[0056] As an example, the support frame 1 includes a main body plate 11, a first support plate 12, and a second support plate 13. The first support plate 12 and the second support plate 13 extend from the two side edges of the main body plate 11 in the same direction. The first support plate 12 is provided with a first mounting position 14, which facilitates the installation of a coil spring mechanism 4. The coil spring mechanism 4 is connected to the first end of the roller 2 and controls the rotation of the roller 2 to retract or unfold the branch belt 3. The second support plate 13 is provided with a second mounting position 15, which facilitates the installation of a locking mechanism 5. The locking mechanism 5 is connected to the second end of the roller 2 and controls the roller 2 to be in a locked or unlocked state. This ensures that the branch belt winding structure can separate obstacles such as tree branches while preventing obstacles from rebounding and scratching the vehicle body or windshield, thus improving the practicality of the equipment.

[0057] In one embodiment, reference is made to Figure 2 The coiling spring mechanism 4 includes an inner coiling spring cover 41, an outer coiling spring cover 42, a retainer 43, and a coiling spring body 44. The first side of the inner coiling spring cover 41 is mounted on the first side of the support frame 1, and the outer coiling spring cover 42 is fixed on the second side of the inner coiling spring cover 41. The inner coiling spring cover 41 and the outer coiling spring cover 42 cooperate to form a first accommodating space. The coiling spring body 44 and the retainer 43 are both installed in the first accommodating space. The first end of the retainer 43 is connected to the first end of the coiling shaft 2, and the second end of the retainer 43 passes through the inner coiling spring cover 41 and is connected to the coiling spring body 44.

[0058] As an example, the inner cover 41 of the coil spring is installed on the first side of the support frame 1, specifically on the first mounting position 14 of the first support plate 12. The outer cover 42 of the coil spring is installed on the inner cover 41 of the coil spring. The inner cover 41 and the outer cover 42 of the coil spring cooperate to form a first accommodating space. The coil spring body 44 and the card holder 43 are both installed in the first accommodating space. That is, the coil spring body 44 and the card holder 43 are both located in the first accommodating space and are connected to the inner cover 41 of the coil spring and / or the outer cover 42 of the coil spring. The first end of the retainer 43 is connected to the first end of the reel 2, and the second end of the retainer 43 passes through the inner cover 41 of the spring and is connected to the spring body 44. In this way, the spring body 44 is confined within the first accommodating space. The retainer 43 rotates forward or backward with the reel 2, thereby causing the spring body 44 to tighten or loosen. When the branch belt 3 is unfolded, the reel 2 rotates and causes the retainer 43 and the spring body 44 to loosen. Conversely, when the branch belt 3 is retracted, the spring body 44 tightens, causing the reel 2 to rotate in the opposite direction, thereby causing the branch belt 3 to be rewound onto the reel 2. This makes it easy to retract or unfold the branch belt 3, avoids the branch belt 3 being exposed to the outside for a long time, increases the weather resistance and service life of the branch belt 3, prevents product corrosion and aging, and has good reliability.

[0059] In one embodiment, reference is made to Figure 3 and Figure 4The locking mechanism 5 includes a ratchet 51, a brake lever 52, and a brake pawl 53. The ratchet 51 is mounted on the second side of the support frame 1. The brake lever 52 is rotatably mounted inside the scroll 2 and can rotate with the scroll 2. The brake pawl 53 is mounted on the end of the brake lever 52 and has a braking part 54. The braking part 54 is connected to the ratchet 51 to prevent the scroll 2 from rotating.

[0060] As an example, the locking mechanism 5 includes a ratchet 51, a brake lever 52, and a brake pawl 53. The ratchet 51 is mounted on the second side of the support frame 1, specifically on the second mounting position 15 of the second support plate 13. The ratchet 51 is fitted onto the second end of the scroll 2. The brake lever 52 is rotatably mounted inside the scroll 2 and can rotate with the scroll 2. The brake lever 52 passes through the scroll 2 and can rotate inside the scroll 2 or rotate with the scroll 2. The brake pawl 53 is mounted on the end of the brake lever 52 and has a braking part 54. The braking part 54 is used to engage with the ratchet 51 to prevent the scroll 2 from rotating. In this example, when the branch belt 3 is pulled outward, if the rotation speed of the reel 2 exceeds the preset speed, the brake pawl 53 can drive the brake lever 52 to rotate relative to the reel 2. At this time, the brake part 54 will engage with the ratchet 51, which can block the movement of the brake lever 52, thereby blocking the rotation of the reel 2, so as to lock the movement of the branch belt 3 and prevent the branch belt 3 from being pulled out. That is to say, if the branch belt 3 is pulled out too quickly, the locking function will be triggered. When the rotation speed of the reel 2 is within the normal range, the brake pawl 53 does not drive the brake lever 52 to rotate relative to the reel 2. At this time, the brake part 54 will not engage with the ratchet 51, and will not block the movement of the brake lever 52. The reel 2 can rotate normally, and the branch belt 3 can be pulled out freely.

[0061] In one embodiment, reference is made to Figure 3 and Figure 4 The locking mechanism 5 also includes a return spring 55; the brake pawl 53 is also provided with a spring mounting part 56, one end of the return spring 55 is connected to the spring mounting part 56, and the other end of the return spring 55 is connected to the end face of the roller 2; the brake part 54 and the spring mounting part 56 are provided on opposite sides of the brake pawl 53 and are located on opposite sides of the brake lever 52.

[0062] As an example, the locking mechanism 5 also includes a return spring 55; a spring mounting part 56 is also provided on the brake pawl 53, one end of the return spring 55 is connected to the spring mounting part 56, and the other end of the return spring 55 is connected to the end face of the roller 2; the brake part 54 and the spring mounting part 56 are provided on opposite sides of the brake pawl 53 and on opposite sides of the brake lever 52; by utilizing the elasticity of the return spring 55, the brake part 54 of the brake pawl 53 can be returned to the initial position, so that the brake part 54 and the ratchet 51 are not jammed, the locking mechanism 5 is in the unlocked state, and the branch belt 3 can be pulled out freely. In this example, when the branch belt 3 is pulled outward, if the rotation speed of the reel 2 exceeds the preset speed, the brake pawl 53 can drive the brake lever 52 to rotate relative to the reel 2. At this time, the brake part 54 will engage with the ratchet 51, which can block the movement of the brake lever 52, thereby blocking the rotation of the reel 2, so as to lock the movement of the branch belt 3 and prevent the branch belt 3 from being pulled out. That is to say, if the branch belt 3 is pulled out too quickly, the locking function will be triggered. When the acceleration decreases, the rotation speed of the reel 2 is within the normal range. Using the elasticity of the return spring 55, the brake part 54 of the brake pawl 53 can return to the initial position. The brake pawl 53 does not drive the brake lever 52 to rotate relative to the reel 2. At this time, the brake part 54 will not engage with the ratchet 51 and will not block the movement of the brake lever 52. The reel 2 can rotate normally, the locking mechanism 5 is in the unlocked state, and the branch belt 3 can be pulled out freely.

[0063] In one embodiment, reference is made to Figure 5 The branch belt winding structure also includes a fixed frame 6, a recovery bracket 7, and a limiting lock 8; the support frame 1 is installed on the fixed frame 6; the recovery bracket 7 is fixed on the fixed frame 6, and an movable gap is formed between the recovery bracket 7 and the fixed frame 6; the second end of the branch belt 3 passes through the movable gap, and the second end of the branch belt 3 is provided with a limiting lock 8, which is detachably connected to the recovery bracket 7.

[0064] As an example, the branch belt winding structure also includes a fixing frame 6, a recovery bracket 7, and a limiting lock 8. The fixing frame 6 is fixed to the vehicle, and then the support frame 1 is installed on the fixing frame 6. The recovery bracket 7 is fixed to the fixing frame 6, forming a movable gap between the recovery bracket 7 and the fixing frame 6. The second end of the branch belt 3 passes through the movable gap, and the second end of the branch belt 3 is provided with a limiting lock 8. The limiting lock 8 is detachably assembled on the locking plate 72 of the recovery bracket 7. This arrangement can lock the branch belt 3 and prevent it from being completely wound onto the reel 2, affecting its next use. The limiting lock 8 is made of high-strength alloy steel material with a hard plastic coating such as PA, and the recovery bracket 7 is made of hot-rolled steel material with magnetic properties. When the branch belt 3 retracts, the limiting lock 8 can be effectively attracted to the recovery bracket 7, thereby fixing the branch belt 3 and making the equipment more convenient to use. It can effectively prevent the limiting lock 8 from making abnormal noise during vehicle operation.

[0065] In one embodiment, reference is made to Figure 5 The fixing frame 6 includes a fixing plate 61 and a first support plate 62 extending vertically from one side of the fixing plate 61. The support frame 1 is mounted on the fixing plate 61. The recycling bracket 7 includes a second support plate 71. The second support plate 71 is connected to the first support plate 62, and an movable gap is formed between the two.

[0066] As an example, the mounting bracket 6 includes a mounting plate 61 and a first support plate 62 extending vertically from one side of the mounting plate 61. The mounting plate 61 is fixed to the vehicle, and then the support frame 1 is mounted on the first support plate 62. The recycling bracket 7 includes a second support plate 71, which is connected to the first support plate 62, and a movable gap is formed between them. The second end of the branch belt 3 passes through the movable gap, and the second end of the branch belt 3 is provided with a limit lock 8. The limit lock 8 is detachably mounted on the locking plate 72 of the recycling bracket 7. This arrangement can lock the branch belt 3 to prevent it from being completely rolled into the reel 2 and affecting the next use.

[0067] In one embodiment, reference is made to Figure 5 The recovery bracket 7 also includes a locking plate 72 extending horizontally from one side of the second support plate 71. The support surface of the locking plate 72 has a stepped structure, and the support surface of the limit lock 8 matches the support surface of the locking plate 72.

[0068] As an example, the recycling bracket 7 also includes a locking plate 72 extending horizontally from one side of the second support plate 71. The support surface of the locking plate 72 has a stepped structure. The support surface of the limit lock 8 matches the support surface of the locking plate 72, which can further increase the friction between the two and improve the fixing effect of the limit lock 8.

[0069] In one embodiment, reference is made to Figure 6 The limiting latch 8 includes a lock frame 81, a door lock 82, and a locking element 83; the lock frame 81 includes a first connecting arm 811, a second connecting arm 812 and a third connecting arm 813 extending from both ends of the first connecting arm 811 in the same direction; the second end of the branch belt 3 is connected to the first connecting arm 811, the first end of the door lock 82 is fixed to the free end of the second connecting arm 812, and the second end of the door lock 82 is provided with a retractable fixing pin 814, which may or may not abut against the free end of the third connecting arm 813; the locking element 83 is installed on the door lock 82 to restrict the extension and retraction of the fixing pin 814.

[0070] As an example, the lock frame 81 includes a first connecting arm 811, a second connecting arm 812, and a third connecting arm 813, the second connecting arm 812 and the third connecting arm 813 extending from both ends of the first connecting arm 811 in the same direction; the second end of the branch band 3 is connected to the first connecting arm 811, the first end of the door lock 82 is fixed to the free end of the second connecting arm 812, the second end of the door lock 82 is provided with a retractable fixing pin 814, and the locking member 83 is installed on the door lock 82 to restrict the extension and retraction of the fixing pin 814; when the fixing pin 814 extends, it connects with the third connecting arm 811... When the free ends of the third connecting arm 813 abut against each other, the locking element 83 locks the fixing pin 814, and the limit lock 8 is in a fixed state. When the fixing pin 814 is retracted and no longer abuts against the free end of the third connecting arm 813, the locking element 83 does not lock the fixing pin 814, and the limit lock 8 is in an unlocked state. This design allows the free end of the branch belt 3 to be fixed in a designated position by the limit lock 8 after the branch belt 3 is pulled apart, enabling the branch belt 3 to separate obstacles such as tree branches and provide protection. At the same time, the limit lock 8 is easy to unlock and facilitates the disassembly and retrieval of the branch belt 3. The limit lock 8 is similar to a gourd-shaped carabiner and has a built-in safety nut. After the safety nut is unscrewed from the fastened position, the lock can be unlocked by manually squeezing the movable handle of the lock.

[0071] This invention provides a vehicle, with reference to... Figure 7 , Figure 8 and Figure 9 It includes a branch belt retractable structure, a luggage frame structure 9, and a hanging lug 10; the luggage frame structure 9 is installed on the roof of the vehicle body, the branch belt retractable structure is installed on the front of the luggage frame structure 9, the hanging lug 10 is installed on the front fender of the vehicle, and the branch belt 3 of the branch belt retractable structure is connected to the hanging lug 10.

[0072] As an example, the luggage frame structure 9 is installed on the roof of the vehicle body, the branch belt retractable structure is installed on the front of the luggage frame structure 9, the hanger 10 is installed on the front fender of the car, and the branch belt 3 of the branch belt retractable structure is connected to the hanger 10 through the limit lock 8, so that the branch belt 3 can be extended and used to block tree branches and protect the windshield. In use, the support frame 1 is fixed to the front of the luggage frame structure 9. The scroll 2 is fitted onto the support frame 1, and a limiting groove is pre-drilled on the scroll 2. The branch tape 3 is folded in half and sewn onto the pin, and then the pin is installed into the limiting groove of the scroll 2 and fixed by the bolts at both ends of the limiting groove. The branch tape 3 is wound around the scroll 2. The coiling spring mechanism 4 is installed on the first side of the support frame 1 and connected to the first end of the scroll 2. It controls the rotation of the scroll 2, causing the branch tape 3 to retract or unfold. When the branch tape 3 unfolds, the coiling spring mechanism 4 relaxes, and the scroll 2 rotates accordingly; conversely, when the branch tape 3 is retracted, the coiling spring mechanism 4 tightens, causing the scroll 2 to rotate in the opposite direction, thus... The branch tape 3 is rewound onto the reel 2, which facilitates its winding and unwinding, preventing it from being exposed to the elements for extended periods. This increases the branch tape 3's weather resistance and lifespan, prevents corrosion and aging, and ensures high reliability. The locking mechanism 5 is installed on the second side of the support frame 1 and connected to the second end of the reel 2. It controls the reel 2 to be in a locked or unlocked state. When the branch tape 3 is pulled outwards, excessive speed will trigger the locking mechanism 5, locking the reel 2 and preventing it from being pulled. When the locking mechanism 5 is not activated, the reel 2 is unlocked, allowing it to rotate normally and the branch tape 3 to be pulled. When in use, the branch strip 3 can flexibly block tree branches from rebounding and hitting the car body due to the forced cutting of branches by traditional metal wires, protecting the windshield and preventing scratches on the car body. When the branch strip 3 is not working, the limit lock 8 opens, and the branch strip 3 can be detached from the lug 10 on the front fender, making the branch strip 3 detachable. This greatly increases the convenience and efficiency of installation and removal for car owners.

[0073] In one embodiment, reference is made to Figure 7 The luggage frame structure 9 includes a longitudinal beam 91, a mounting bracket 92, a cross beam 93, and an inclined column 94. The longitudinal beam 91 is mounted on the roof of the vehicle body via the mounting bracket 92, and the two ends of the cross beam 93 are connected to a longitudinal beam 91 respectively. One end of the inclined column 94 is connected to the longitudinal beam 91, and the other end of the inclined column 94 is connected to the cross beam 93. The branch belt retraction structure is fixed to the bottom of the inclined column 94.

[0074] As an example, the longitudinal beams 91 and transverse beams 93 are integrated into the frame of the luggage frame structure 9 through riveting, screwing, or welding processes via the diagonal pillars 94. The frame is then screwed to the mounting point on the roof of the vehicle. The branch belt retractable structure is in its retracted state and is located at the front of the luggage frame structure 9, screwed to the bottom of the diagonal pillars 94 to reduce wind resistance and minimize the exposure of the retaining latches 8 after retraction. This position of the branch belt retractable structure is optimal, as it not only separates obstacles such as tree branches but also avoids obstructing the driver's view. Furthermore, the branch belt retractable structure is located at the bottom of the diagonal pillars 94 and can be largely concealed by the roof and luggage frame structure 9, significantly reducing eddy current resistance and avoiding aesthetic issues caused by excessive exposure.

[0075] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
