Description

Technical Field

[0001] This invention belongs to the field of automotive technology, and specifically relates to a fender protection device used for preventing car scratches. Background Technology

[0002] Currently, parking spaces in Chinese cities are narrow (standard parking space size is 5000mm×2500mm) and scarce. Meanwhile, cars sold on the market are becoming increasingly larger, leading to frequent door scratches during parking. Owners of new cars, high-end cars, or those who are very concerned about their vehicle's appearance tend to protect their cars by choosing spacious parking spots or purchasing car scratch protection products rather than frequently spending money on expensive paint repairs. However, these methods have their limitations. Finding spacious parking spaces in congested areas of densely populated cities like Beijing, Shanghai, Guangzhou, and Shenzhen is often time-consuming and laborious. Common car door scratch protection products on the market include door bumper strips and integrated car protective covers. Traditional bumper strips (such as patent application CN202430275079.3) have limited protection range and affect the car's appearance, while integrated protective covers (such as patent application CN202421110458.8) are expensive and have complex installation and storage methods, failing to meet the needs of most users. Summary of the Invention

[0003] To address at least one of the problems existing in current technologies, this invention provides a fender umbrella device for preventing car scratches, solving the problem of frequent door scratches when parking in narrow urban parking spaces (typically 5000mm × 2500mm) and increasingly larger cars on the market. This invention's device unfolds close to the edge of the car when parked, effectively preventing scratches from adjacent cars opening their doors. When not in use, it is hidden under the car body, preserving the vehicle's streamlined appearance. This invention's concealed design balances protection and aesthetics, offers convenient and quick unfolding and storage, and is inexpensive, meeting car owners' demands for aesthetics, convenience, and cost-effectiveness.

[0004] To achieve the purpose of this invention, this invention discloses a fender protection umbrella device for preventing car scratches, including a pedal storage box, a safety foot pedal for getting in and out of the vehicle, and a foldable and concealed fender protection umbrella device.

[0005] The safety foot pedal for getting on and off the vehicle is slidably mounted on the foot pedal storage box. The foldable and concealed anti-scratch fender protection device is installed in the mounting cavity of the safety foot pedal for getting on and off the vehicle. In the non-working state, the foldable and concealed anti-scratch fender protection device is stored in the mounting cavity. The folding, concealed anti-scratch wing protection umbrella device includes a first rod, a second rod, a movable pedal, a canopy pivot, a canopy, and a third rod. The bottom of the first rod is rotatably mounted in the mounting cavity of the vehicle entry / exit safety foot pedal, and its top is rotatably connected to the bottom of the second rod via a joint gear. The top of the second rod is rotatably connected to the bottom of the movable pedal. The canopy pivot is rotatably connected to the first rod, and the canopy is rotatably mounted on the canopy pivot. The canopy includes a fixed fabric and an unfolding fabric. One end of the fixed fabric is connected to the movable pedal, and one end of the unfolding fabric is connected to the third rod. The third rod is rotatably mounted at the bottom of the movable pedal.

[0006] Furthermore, the side wall of the pedal storage box is provided with a sliding groove, and the safety foot pedal for getting on and off the vehicle is provided with a sliding rail that cooperates with the sliding groove.

[0007] Furthermore, a push-to-pop reset device is provided on the slide groove at one end near the rear wall of the box. When the driver presses the safety foot pedal horizontally to get in and out of the car, the top of the fixed anti-slip foot pedal is pressed to squeeze the push-to-pop reset device, and the safety foot pedal pops out of the foot pedal storage box. When it pops out, pressing it horizontally again will retract the safety foot pedal into the foot pedal storage box.

[0008] Furthermore, the safety foot pedal for getting on and off the vehicle and the foot pedal storage box are equipped with cooperating limit blocks to limit the sliding of the safety foot pedal for getting on and off the vehicle. Furthermore, the top of the foot pedal storage box is equipped with a first limit block, and the top of the safety foot pedal for getting on and off the vehicle is equipped with a second limit block.

[0009] When the driver presses the safety foot pedal, the slide rail of the safety foot pedal slides quickly inward in the slide groove of the pedal storage box. The top of the fixed anti-slip pedal in the safety foot pedal squeezes and presses the pop-out reset device, and the safety foot pedal pops out of the pedal storage box at a uniform speed. When the pop-out distance is the preset distance, the second limit block on the safety foot pedal is locked by the first limit block on the top of the pedal storage box, and the safety foot pedal is fixed.

[0010] Furthermore, both the fixed fabric and the unfolded fabric are equipped with mutually cooperating soft magnets.

[0011] Furthermore, anti-collision guard strips are installed on the movable pedal, the first rod, and the third rod to prevent the rigid components of the folding and concealed anti-scratch fender protection device from causing scratch damage to the vehicle body when subjected to external impact.

[0012] Furthermore, the folding concealed anti-scratch fender protection umbrella device also includes a rainproof differential gear box, which is installed in the mounting cavity of the safety foot pedal for getting on and off the vehicle, and is connected to the umbrella fabric pivot.

[0013] Furthermore, the mounting cavity of the safety foot pedal for getting on and off the vehicle, the first rod, the second rod, the third rod, and the bottom of the movable pedal are all equipped with fixed joint gears. The joint shaft passes through the circular holes of the above components that coincide with the joint gears, so that the front wall of the safety foot pedal for getting on and off the vehicle is coupled and rotated and horizontally limited between the first rod, between the first rod and the second rod, between the third rod and the movable pedal, and between the first rod and the movable pedal.

[0014] Furthermore, the rainproof differential gear box includes a joint shaft, a first sliding differential gear, a second sliding differential gear, a third sliding differential gear, and a fixed differential gear. The first and second sliding differential gears are arranged opposite each other on the joint shaft, and the first sliding differential gear is fixed to the bottom of the first rod. The third sliding differential gear and the fixed differential gear are arranged opposite each other on the umbrella fabric shaft, and the third sliding differential gear and the fixed differential gear are meshed with the first and second sliding differential gears. When the first rod rotates, it drives the umbrella fabric shaft to rotate through the rainproof differential gear box, and the umbrella fabric unfolds vertically at the same speed as the first and second rods.

[0015] The number of teeth on the sliding differential gear and the fixed differential gear are in a multiple relationship. When the lever drives the sliding differential gear to rotate, the fixed differential gear rotates in conjunction with the sliding differential gear and the sliding differential gear. At the same time, the fixed differential gear drives the umbrella fabric shaft to rotate.

[0016] Furthermore, the device includes five operating states: retractable safety foot pedal for getting on and off the vehicle, horizontally popped-out safety foot pedal for getting on and off the vehicle, vertically raised wing parachute, partially deployed wing parachute, and fully deployed wing parachute by rotation.

[0017] Furthermore, when the safety foot pedals for getting in and out of the vehicle are in the retracted state, the safety foot pedals are located inside the pedal storage box, which is hidden under the vehicle chassis and will not affect the aesthetics of the vehicle's streamlined design. When the safety foot pedal for getting on and off the vehicle is pressed, the safety foot pedal pops out horizontally and evenly into the pedal storage box. When the safety foot pedal for getting in and out of the vehicle is in the horizontally extended position, pulling the movable pedal vertically upward causes the first lever to rotate, which in turn drives the first sliding differential gear to rotate. The fixed differential gear is coupled with the first and second sliding differential gears to rotate. At the same time, the fixed differential gear drives the umbrella fabric shaft to rotate. The umbrella fabric on the umbrella fabric shaft unfolds vertically at the same speed as the first and second levers. When the angle between the second and first levers rotates from 0° to 180°, the movable pedal can no longer be pulled vertically upward, and the folding and concealed anti-scratch wing protection umbrella device is partially unfolded. With the folding concealed anti-scratch wing protection device partially unfolded, rotate the third rod outward to rotate and unfold the outer fabric. When the angle between the third rod and the bottom of the movable pedal rotates from 0° to 180°, the third rod can no longer rotate, and the folding concealed anti-scratch wing protection device is fully unfolded.

[0018] Compared with the prior art, the beneficial effects that the present invention can achieve are at least as follows: (1) Currently, the most common car door anti-scratching products on the market are door anti-collision strips and integrated car protective covers. Traditional anti-collision strips have limited protection range and affect the appearance of the car body, while integrated protective covers are expensive and have complicated installation and storage methods. Compared with the above products, the hidden design of this invention takes into account both protection and aesthetics, and the unfolding and storage methods are convenient and quick. Moreover, the price is low, which meets the car owners' pursuit of aesthetics, convenience and cost performance.

[0019] (2) In addition to being applied to situations where the car owner manually unfolds and stores the vehicle, the present invention can be further improved in terms of technology and convenience by adding a power system to enable automatic unfolding when parked and automatic storage via remote control.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] like Figure 1 As shown in the figure, an embodiment of the present invention discloses a fender protection umbrella device for preventing car scratches, including a pedal storage box 1, a safety foot pedal for getting in and out of the car 2, and a foldable and concealed anti-scratch fender protection umbrella 3.

[0034] The safety foot pedal 2 for getting on and off the vehicle is slidably mounted on the pedal storage box 1. For example... Figure 2 As shown, the pedal storage box 1 includes a circular first gasket 4, a box body 5, a press-to-release reset device 7, and a first limiting block 8. The pedal storage box 1 is fixed to the car chassis by screws passing through the first gasket 4. Symmetrical sliding grooves 6 are provided on the left and right side walls 9 of the box body 5. The slide rail 11 on the safety foot pedal 2 can slide horizontally in the sliding grooves 6. A press-to-release reset device 7 is provided on the sliding groove 6 and near the rear wall 10 of the box body (the press-to-release reset device is a known existing structure, such as the similar application in CN 219516533U, which will not be elaborated here). The first limiting block 8 is located on the top of the pedal storage box 1 and works together with the second limiting block 12 on the safety foot pedal 2.

[0035] like Figure 3As shown, the safety foot pedal 2 for getting on and off the vehicle includes a fixed anti-slip foot pedal 13 and a second limiting block 12. A slide rail 11 is provided on the narrow side wall of the fixed anti-slip foot pedal 13, and the second limiting block 12 is located on the top of the long side of the fixed anti-slip foot pedal 13. The slide rail 11 on the safety foot pedal 2 can slide horizontally in the slide groove 6 on the left and right side walls 9 of the pedal storage box 1. By pressing the pop-out reset device 7 and cooperating with the horizontal sliding, the safety foot pedal 2 can be popped out of the pedal storage box 1 and retracted into the pedal storage box 1. The second limiting block 12 on the safety foot pedal 2 cooperates with the first limiting block 8 on the pedal storage box 1 to limit the safety foot pedal 2. When the driver presses the safety foot pedal 2 horizontally, the rear edge of the fixed anti-slip foot pedal 13 is squeezed and pressed to release the reset device 7, thereby popping the safety foot pedal 2 out of the pedal storage box 1. When the safety foot pedal 2 is popped out, pressing it horizontally again will retract the safety foot pedal 2 into the pedal storage box 1.

[0036] like Figure 4 As shown, the folding concealed anti-scratch fender protection umbrella 3 includes a movable foot pedal 22, a rainproof differential gear box 14, an umbrella fabric pivot 15, an umbrella fabric 16 made of double-coated flame-retardant material, a first rod 17, a second rod 18, a third rod 26, a joint gear 19, a joint pivot 20, and a 2mm thick soft magnet 21. An installation cavity is provided on the safety foot pedal 2 for getting in and out of the vehicle and on one side of the anti-slip foot pedal 13. The folding concealed anti-scratch fender protection umbrella 3 is installed on the installation cavity. Differential gear boxes 14 are provided on both sides of the installation cavity. The two ends of the umbrella fabric pivot 15 pass through the two differential gear boxes 14 respectively.

[0037] Two rainproof differential gear boxes 14 are connected to the two ends of the hollow side wall of the safety foot pedal 2 for getting on and off the vehicle. The umbrella cloth shaft 15 passes through the rainproof differential gear box 14. The first sliding differential gear 24 inside the rainproof differential gear box 14 is fixedly connected to the first rod 17. The rainproof differential gear box 14 can prevent the internal gear set from getting wet and rusting. The top of the umbrella cloth 16 is connected to the movable pedal 22 and the third rod 26, and the bottom is connected to the umbrella cloth shaft 15.

[0038] The bottom of the umbrella fabric 16 is rotatably mounted on the umbrella fabric pivot 15. The umbrella fabric 16 includes a fixed fabric and two unfolding fabrics located on both sides of the fixed fabric, with the sides of the unfolding fabrics sewn to the fixed fabric. In one embodiment, the fixed fabric is rectangular, and the unfolding fabrics are fan-shaped. When the umbrella fabric 16 is unfolded, it presents an overall shape of a central rectangle with two fan-shaped wings. The top of the fixed fabric is fixedly connected to the movable pedal 22, and the top of the unfolding fabric is connected to the third rod 26, which is rotatably mounted at the bottom of the movable pedal 22. Soft magnets 21 are attached to the two curved edges of the fan-shaped fabric and the back of the rectangular fabric. The soft magnets 21 on the fan-shaped fabric and the soft magnets 21 on the rectangular fabric can fix the fan-shaped fabric to the rectangular fabric when not unfolded, facilitating neat storage. Rotating the third rod 18 outward causes the unfolding fabric to unfold and straighten.

[0039] In one embodiment, the first member 17, the second member 18, and the third member 18 are rigid members.

[0040] In one embodiment, the first rod 17, the second rod 18, and the third rod 18 are hydraulic rods.

[0041] In one embodiment, transparent silicone anti-collision strips 23 are provided on the top of the movable pedal 22 and on both sides of the first rod 17 and the third rod 26 to prevent the rigid components of the folded and hidden anti-scratch fender 3 from causing scratch damage to the vehicle body when subjected to external impact.

[0042] like Figure 5-7 As shown, a circular second pad 27 is vertically arranged at the bottom of the movable pedal 22 to provide a fixed fulcrum for the joint gear 19 below the movable pedal 22; joint gears 19 are fixed in the mounting cavity of the vehicle safety foot pedal 2, at both ends of the first rod 17 and the second rod 18, at one end of the third rod 26, and on the second pad 27. The corresponding joint shafts 20 pass through the circular holes of the above components that coincide with the corresponding joint gears 19, so that the front wall of the vehicle safety foot pedal 2 is coupled and rotated and horizontally limited between the first rod 17, between the first rod 17 and the second rod 18, between the third rod 26 and the second pad 27 at the bottom of the movable pedal 22, and between the second rod 18 and the second pad 27 at the bottom of the movable pedal 22.

[0043] Specifically, such as Figure 8As shown, the rainproof differential gear box 14 is equipped with a corresponding joint shaft 20, a first sliding differential gear 24, a second sliding differential gear 32, a third sliding differential gear 35, and a fixed differential gear 25. The first sliding differential gear 24 and the second sliding differential gear 32 have sliding ball bearings 30 inside. The first sliding differential gear 24 is rotatably connected to the joint shaft 20, and the third sliding differential gear 35 is connected to the umbrella fabric shaft 15. The first sliding differential gear 24 is welded to the bottom of the first rod 17. The joint gear and the first sliding differential gear 24 are located on both sides of the first rod 17, respectively. The fixed differential gear 25 has a fixed limiting bearing 31 inside and is fixedly connected to... On the umbrella fabric rotating shaft 15, the umbrella fabric rotating shaft 15 passes through the joint rotating shaft 20 to limit the sliding differential gear in the rainproof differential gear box 14 in the horizontal and vertical directions, making the device more stable; the number of teeth of the first sliding differential gear 24 and the fixed differential gear 25 are in a multiple relationship, so that when the first rod 17 drives the first sliding differential gear 24 to rotate, the fixed differential gear 25 is coupled to rotate with the first sliding differential gear 24, the second sliding differential gear 32 and the third sliding differential gear 35. At the same time, the fixed differential gear 25 can drive the umbrella fabric rotating shaft 15 to rotate, and the umbrella fabric 16 on the umbrella fabric rotating shaft 15 unfolds vertically at the same speed as the first rod 17 and the second rod 18.

[0044] The fixed differential gear 25 has a fixed limiting bearing 31 inside and is fixedly connected to the umbrella fabric rotating shaft 15. The fixed differential gear 25 and the umbrella fabric rotating shaft 15 rotate simultaneously. The fixed differential gear 25 is coupled to the sliding differential gear 24 for rotation. The first sliding differential gear 24 is welded to the bottom of the first rod 17. When the first rod 17 rotates in the vertical direction, due to the joint gear set between the first rod 17 and the second rod 18, the rotation of the first rod 17 drives the second rod 18 to rotate in the vertical direction. When the second rod 18 rotates, it drives the movable pedal 22 to rise vertically. The top of the umbrella fabric 16 is fixed on the movable pedal 22, and the umbrella fabric 16 unfolds vertically.

[0045] like Figure 9-13 As shown, the invention has five operating states: safety pedal storage, safety pedal horizontal pop-out, wing parachute vertical rise, wing parachute partially deployed, and wing parachute fully deployed by rotation.

[0046] like Figure 14 As shown, when the safety foot pedal 2 is in the retracted state, it is located inside the pedal storage box 1, which is hidden under the car chassis and does not affect the aesthetics of the car body's streamline.

[0047] like Figure 15As shown, when the driver presses the safety foot pedal 2, the slide rail 11 of the safety foot pedal 2 slides rapidly inward in the slide groove 6 of the pedal storage box 1 (the slide rail 11 on the outer side of the safety foot pedal 2 connects with the slide groove 6 on the inner side of the pedal storage box 1, allowing for relative sliding similar to a drawer). The inner edge of the fixed anti-slip pedal 13 in the safety foot pedal 2 presses against the pop-out reset device 7, and the safety foot pedal 2 pops out of the pedal storage box 1 at a uniform speed. When it pops out to a preset distance (in one embodiment, the preset distance is 160mm), the second limiting block 12 on the safety foot pedal 2 is blocked by the first limiting block 8 at the top of the pedal storage box 1, and the safety foot pedal 2 is fixed in place.

[0048] like Figure 16-17 As shown, when the safety foot pedal 2 is in the horizontally extended state, the driver pulls the movable pedal 22 vertically upwards. The joint gear 19 between the second pad 27 and the second rod 18 at the bottom of the movable pedal 22, the joint gear 19 between the second rod 18 and the first rod 17, and the joint gear 19 between the first rod 17 and the front wall of the safety foot pedal 2 engage in coupled rotation and horizontal limiting. The number of teeth on the first sliding differential gear 24 and the fixed differential gear 25 are in a multiple relationship, so that when the first rod 17 drives the first sliding differential gear 24 to rotate, the fixed differential gear 25 and the first sliding differential gear... Gear 24 and the second sliding differential gear 32 rotate in coupling, while the fixed differential gear 25 drives the umbrella fabric shaft 15 to rotate. The umbrella fabric 16 on the umbrella fabric shaft 15 unfolds vertically at the same speed as the first rod 17 and the second rod 18. When the angle between the second rod 18 and the first rod 17 rotates from 0° to 180°, the joint gear 19 stops rotating, and the movable pedal 22 can no longer be pulled vertically upward. The folding and concealed anti-scratch wing protection umbrella 3 is in a partially unfolded state, which plays a basic protective role. At this time, the soft magnets 21 on the two arc-shaped sides of the unfolded fabric remain attached to the soft magnets 21 on the back of the rectangular umbrella surface.

[0049] like Figure 18 As shown, when the folding concealed anti-scratch fender umbrella 3 is partially unfolded, the car owner rotates the third rod 26 outwards. The joint gear 19 between the second pad 27 at the bottom of the movable pedal 22 and the second rod 18 is coupled and rotated horizontally. The soft magnets 21 on the arc-shaped edges of the two unfolded fabrics of the umbrella 16 gradually separate from the soft magnets 21 on the back of the rectangular umbrella surface. The third rod 18 drives the unfolded fabric to rotate outwards and unfold. When the angle between the third rod 18 and the bottom of the movable pedal 22 rotates from 0° to 180°, the third rod 18 can no longer rotate, and the folding concealed anti-scratch fender umbrella 3 is fully unfolded, expanding the protection area.

[0050] The concealed design of the foregoing embodiments of the present invention balances protection and aesthetics, is convenient and quick to unfold and store, and is inexpensive, meeting car owners' pursuit of aesthetics, convenience and cost-effectiveness.

[0051] In a preferred embodiment, besides being applied to manual unfolding and folding by the car owner, this invention can further enhance its technological appeal and convenience by adding a power system to enable automatic unfolding when parked and automatic folding via remote control. Alternatively, the umbrella's fan surface can be used as an advertising display surface to spray advertisements for automotive-related products, further reducing the product's price through advertiser sponsorship. As described above, this invention can be effectively implemented.

[0052] This invention is applicable to situations where urban parking spaces are narrow (the standard size of a parking space is 5000mm × 2500mm) and the size of cars sold on the market is getting larger and larger, resulting in frequent scratches of car doors when parking. The device in this invention unfolds and fits close to the edge of the car when parking, effectively preventing scratches from cars in adjacent parking spaces when they open their doors. When not in use, it can be hidden and stored at the bottom of the car body without disrupting the car's streamlined appearance.

[0053] Currently, common car door anti-scratch products on the market include door bumper strips and integrated car protective covers. Traditional bumper strips offer limited protection and affect the car's appearance, while integrated protective covers are expensive and complex to install and store. Compared to these products, the concealed design of this invention balances protection and aesthetics, offers convenient and quick unfolding and storage, and is priced significantly lower than integrated protective covers, meeting car owners' demands for aesthetics, convenience, and cost-effectiveness.

[0054] This invention is used when the car is parked. According to the Road Traffic Safety Law of the People's Republic of China, this invention does not involve assembling motor vehicles or unauthorized alteration of the registered engine, structure, construction or characteristics of motor vehicles, and it will not operate when the motor vehicle is on the road, and does not fall under the category of motor vehicle modification.

[0055] The above description is merely a preferred embodiment of the present invention. Those skilled in the art can make various other variations or modifications without departing from the principles of the invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.

When the safety foot pedal (2) is in the horizontal pop-out state, the movable pedal (22) is pulled vertically upward, the first rod (17) rotates, which drives the first sliding differential gear (24) to rotate. The fixed differential gear (25) is coupled with the first sliding differential gear (24) and the second sliding differential gear (32) to rotate. At the same time, the fixed differential gear (25) drives the umbrella fabric shaft (15) to rotate. The umbrella fabric (16) on the umbrella fabric shaft (15) unfolds vertically at the same speed as the first rod (17) and the second rod (18). When the angle between the second rod (18) and the first rod (17) rotates from 0° to 180°, the movable pedal (22) can no longer be pulled vertically upward, and the folding and hidden anti-scratch wing protection umbrella device (3) is in a partially unfolded state. With the folding concealed anti-scratch wing protection device (3) partially unfolded, rotate the third rod (26) outward to rotate and unfold the unfolding cloth. When the angle between the third rod (26) and the bottom of the movable pedal (22) rotates from 0° to 180°, the third rod (26) can no longer rotate, and the folding concealed anti-scratch wing protection device (3) is fully unfolded.
