Description

Technical Field

[0001] This invention belongs to the field of vehicle accessory technology, and relates to a bicycle rack assembly installed in a vehicle and the vehicle itself. Background Technology

[0002] In addition to serving as a means of transportation, vehicles are increasingly taking on the function of carrying other outdoor activity equipment to meet users' diverse travel needs. In recent years, with the popularization of outdoor cycling activities, more and more individuals or families are choosing to drive to the suburbs or scenic areas for cycling.

[0003] Currently, there are two main ways for users to carry bicycles in their vehicles: one is to disassemble the bicycle and install it inside the vehicle. This method is cumbersome and takes up passenger space, so passenger comfort needs improvement. The other is to purchase a separate bicycle rack and assemble it. Existing bicycle racks are mainly divided into two categories: one type is installed using the roof rack, fixing the bicycle rack to the roof. This type of rack may need to be disassembled when passing through tunnels, bridges, or other height-restricted areas, so its ease of operation and safety need improvement. The other type is a rear-mounted rack installed at the rear of the car. This type of rack is large and cannot be stored inside the car. It needs to be temporarily installed before each trip and disassembled after use, so its ease of operation and user experience need optimization. Summary of the Invention

[0004] This application provides a bicycle rack assembly and a vehicle to solve the problems existing in the prior art, avoid occupying passenger space, increase riding comfort, improve the convenience and safety of using the bicycle rack, and optimize the operating experience.

[0007] Optionally, the outer surface of the rear bumper is provided with a license plate mounting area.

[0008] Optionally, the bracket assembly includes: at least one set of wheel fixing mechanisms for clamping or fixing the bicycle wheel; a sliding guide groove formed on the pull-out guide rail or located on an independent component connected to the pull-out guide rail; wherein the wheel fixing mechanism is slidably disposed on the sliding guide groove to adjust the fixing position of the wheel fixing mechanism according to the size of the bicycle.

[0009] Optionally, the wheel fixing mechanism includes a wheel frame assembly; the wheel frame assembly includes a base slidably disposed on the sliding guide groove, one or two support arms, one end of the support arm being hinged to the base, and the other end being detachably mounted with a fastener; the support arm can rotate relative to the base between a folded position and a working position; in the folded position, the support arm is against the inner side of the sliding guide groove or the movable component; in the working position, the support arm is flipped to form an acute angle or a right angle with the horizontal plane.

[0010] Optionally, the wheel fixing mechanism further includes a wheel strap assembly, which includes a strap disc and a one-way locking strap. The strap disc is installed in the sliding guide groove, one end of the one-way locking strap is fixed to the strap disc, and the other end is used to pass through the one-way locking structure of the strap disc. The portion of the one-way locking strap located between the strap disc and the one-way locking structure is used to fix the wheel.

[0011] Optionally, at least one of the fixing opening on the fixing component for receiving the rear bumper plate and / or the outer edge of the rear bumper plate is provided with a sealing strip and / or a decorative cover; when the movable component moves back to the fixing component, the sealing strip and / or the decorative cover fills the space between the fixing opening and the outer edge of the rear bumper plate.

[0012] Optionally, a locking ejection mechanism is also included, which is disposed between the fixed component and the movable component, for locking the movable component when the movable component moves back into the fixed component, and unlocking and ejecting the movable component when the movable component is pressed toward the interior of the vehicle body.

[0013] Optionally, it further includes a driving state locking mechanism, which is used to prevent the movable component from moving outward from the fixed component during vehicle operation; the driving state locking mechanism includes: a locking actuator, disposed between the fixed component and the movable component, having a locked state and an unlocked state; a vehicle speed sensor, used to acquire the real-time vehicle speed signal; and a controller, electrically connected to the vehicle speed sensor and the locking actuator, used to control the locking actuator to switch to the locked state when the real-time vehicle speed signal exceeds a preset threshold, so as to restrict the movable component from sliding relative to the fixed component.

[0015] The above technical solution has the following beneficial effects: The bicycle bracket assembly and vehicle provided in this application integrate the bicycle mounting bracket into the inner side of the movable component of the rear bumper assembly. When the bracket is needed, the user simply slides the movable component backward, exposing the bracket to the outside of the vehicle for securing the bicycle. After use, the movable component slides forward, retracting the bracket into the vehicle interior. The movable component, as part of the rear bumper assembly, restores its original appearance and function. Since the bracket is always integrated with the vehicle, it eliminates the need for separate storage and installation, avoiding space occupation and improving passenger comfort. Furthermore, users can easily use and store the bracket with a simple pull or button press, greatly enhancing ease of use. Compared to existing technologies where the bracket is exposed during use and completely retracted when not in use, this design does not affect the vehicle's appearance and avoids the issues of height restrictions for roof racks and the bulky and difficult-to-store nature of rear-mounted racks, thus improving the user experience.

Detailed Implementation

[0026] The technical solution of the present invention will be further described in detail below with reference to embodiments and accompanying drawings. The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0027] The bicycle rack assembly provided in this application, such as Figure 1 and Figure 2 As shown, it includes: rear bumper assembly 1 and bracket assembly 2.

[0028] The rear bumper assembly 1 includes a movable component 10 and a fixed component 11. The fixed component 11 is fixedly connected to the vehicle body, and the movable component 10 slides relative to the fixed component 11 in the front-rear direction of the vehicle body. The bracket assembly 2 is installed inside the movable assembly 10, and is exposed when the movable assembly 10 slides out toward the rear of the vehicle body, for detachably mounting at least one bicycle 3, such as... Figure 3 As shown; the movable component 10 slides back towards the front of the vehicle body and is used as part of the rear bumper assembly 1, as... Figure 1 As shown.

[0029] In this embodiment, the bracket assembly 2 for mounting the bicycle 3 is integrated inside the movable component 10 of the rear bumper assembly 1. When the function of the bracket assembly 2 is needed, the user only needs to slide the movable component 10 backward to move it out, and the bracket assembly 2 installed inside it will be exposed outside the vehicle to secure the bicycle 3. After use, the movable component 10 is slid forward to move it back, and the bracket assembly 2 is stored inside the vehicle body. The movable component 10, as part of the rear bumper assembly 1, restores its original rear bumper appearance and function. Since the bracket assembly 2 is always integrated with the vehicle, it does not need to be stored and installed separately, avoiding the occupation of interior space and improving the passenger comfort. Moreover, the user can easily use and store the bracket assembly 2 by simply pulling or pressing a button, greatly improving ease of use. At the same time, compared with the prior art where the bracket assembly is exposed when in use and completely stored inside the vehicle body when not in use, it does not affect the appearance of the vehicle and avoids the problems of roof brackets needing to consider height restrictions and rear-mounted brackets being bulky and difficult to store.

[0030] In one alternative implementation, such as Figure 2 As shown, the movable component 10 includes a rear bumper plate 100 and two pull-out guide rails 101 connected to and opposite to the rear bumper plate 100; the fixed component 11 has two sliding grooves, and the two pull-out guide rails 101 are slidably disposed in the two sliding grooves in a one-to-one correspondence. The rear bumper plate 100, as the external part of the movable component 10, can be made of materials and have a shape adapted to the vehicle body; the two pull-out guide rails 101 are fixedly connected in parallel to the inner side (facing the vehicle body) of the rear bumper plate 100, extending along the front-rear direction of the vehicle body, such as... Figure 2 As shown. The fixed component 11 is provided with two corresponding sliding grooves. The cross-sectional shape of the sliding grooves is adapted to the cross-sectional shape of the pull-out guide rail 101. For example, a T-shaped groove, dovetail groove or C-shaped groove is used. Through the cooperation between the pull-out guide rail 101 and the sliding grooves, the smooth sliding of the movable component 10 is realized, while providing high structural strength and load-bearing capacity, which can withstand the weight of the bicycle 3 and the bracket component 2.

[0031] Furthermore, a wear-resistant bushing or lubricating layer can be provided between the pull-out guide rail 101 and the slide groove to reduce frictional resistance and make the pull-out operation of the movable component 10 smoother.

[0032] In an optional embodiment, the outer surface of the rear bumper 100 is provided with a license plate mounting area 100a for mounting the vehicle's license plate, such as... Figures 1 to 6As shown, when the movable component 10 slides backward, the installed license plate moves with the movable component 10, always remaining exposed and avoiding being obstructed by the bracket component 2 or the bicycle 3, thus meeting the road traffic regulations' requirement that the license plate must be clearly visible.

[0033] Optionally, the license plate mounting area 100a can be a flat area on the outer surface of the rear bumper 100, which is provided with license plate mounting holes or license plate fixing brackets for fixing the license plate by means of bolts or clips.

[0034] In one alternative implementation, such as Figure 2 As shown, the bracket assembly 2 includes at least two sets of wheel fixing mechanisms 20 and sliding guide grooves 21. The wheel fixing mechanisms 20 are used to clamp or fix the wheels of the bicycle 3. Each set of wheel fixing mechanisms 20 can be used independently or in combination. For example, for a bicycle 3, a set of wheel frame assemblies 200 can be used to fix the rear wheel 31, while a set of wheel strap assemblies 201 can be used to fix the front wheel 30, or a set of wheel fixing mechanisms 20 can be used in conjunction with other support structures (such as straps, clamps, etc.) to fix a bicycle 3. The sliding guide groove 21 is formed on the pull-out guide rail 101 (for example, a groove along the length direction is formed on the side or top surface of the pull-out guide rail 101) or located on an independent component connected to the pull-out guide rail 101; wherein, the bottom of the wheel fixing mechanism 20 is provided with a sliding element (such as a slider or bolt) that cooperates with the sliding guide groove 21, so that the wheel fixing mechanism 20 can move laterally (left and right) along the bicycle body on the sliding guide groove 21. With the aforementioned adjustable sliding design, users can flexibly adjust the spacing between each set of wheel fixing mechanisms 20 according to the wheel track or frame size of the bicycle 3, to accommodate different types and sizes of bicycles 3, thus improving the versatility and adaptability of the bracket assembly 2. After adjustment, the wheel fixing mechanism 20 can be locked in the predetermined position on the sliding guide groove 21 by locking bolts, wing nuts, or quick-clamping mechanisms.

[0035] In an optional embodiment, the wheel fixing mechanism 20 includes a wheel carrier assembly 200; the wheel carrier assembly 200 includes a base 200a slidably disposed on the sliding guide groove 21, and one or two support arms 200b, one end of each support arm 200b being hinged to the base 200a, and the other end being detachably fitted with a fastener; the support arm 200b is rotatable relative to the base 200a between a folded position and a working position; in the folded position, the support arm 200b is in contact with the inner side of the sliding guide groove 21 or the movable component 10, such as... Figure 4 As shown; in the operating position, the support arm 200b is rotated to form an acute angle or a right angle with the horizontal plane, such as... Figure 6 As shown.

[0036] This embodiment provides a specific implementation of the wheel fixing mechanism 20. A sliding guide groove 21 has a strip-shaped sliding opening along its length. A fastening bolt passes through the strip-shaped sliding opening of the sliding guide groove 21 and is installed on the base 200a. When the fastening bolt is loosened, the base 200a can slide along the strip-shaped sliding opening and rotate around the fastening bolt in the horizontal plane, allowing the entire wheel frame assembly 200 to be slidably and adjustably installed on the pull-out guide rail 101. When the fastening bolt is tightened, the base 200a is secured to the sliding guide groove 200a. One end of the support arm 200b is connected to the base 200a via a hinge shaft, allowing the support arm 200b to rotate around the hinge shaft. The other end of the support arm 200b is provided with fasteners, such as buckles, clamps, fixing ropes, or quick clamps, for contacting the wheel axle, spokes, or tire and providing a fastening force when fixing the bicycle wheel 3.

[0037] The support arm 200b can rotate between two positions: a folded position and a working position. In the folded position, the support arm 200b is approximately parallel to the inner surface of the sliding guide groove 21 or the movable component 10, making the entire wheel frame assembly 200 flat, so that it can be stored in the sliding groove or a separately opened receiving opening in the fixed component 11 when the movable component 10 is moved back. In the working position, the support arm 200b first rotates upward about the first hinge axis arranged laterally along the vehicle body to form an acute angle or a right angle with the horizontal plane, such as... Figure 5 As shown; subsequently, loosen the fastening bolts that slide the base 200a onto the sliding guide groove 21, causing the base 200a to rotate around the fastening bolts in the horizontal plane until the support arm 200b is in a working posture that is approximately perpendicular to the length direction of the vehicle body, as shown. Figure 6 As shown, tighten the fastening bolts to fix the base 200a on the sliding guide groove 21.

[0038] Furthermore, the base 200a can be installed on the sliding guide groove 21 by bolts. When the base 200a needs to slide along the sliding guide groove 21, or when the base 200a needs to rotate in the horizontal direction, the bolts are loosened; when the base 200a needs to be fixed, the bolts are tightened and fixed on the sliding guide groove 21.

[0039] The foldable design of the support arm 200b enables the bracket assembly 2 to switch between the use state and the storage state. This ensures that the bicycle wheel 3 is effectively fixed when in use, and that the bracket assembly 2 can be completely stored inside the movable assembly 10 when not in use, without taking up extra space or affecting the normal driving and appearance of the vehicle.

[0040] like Figure 3As shown, when there are two support arms 200b, one of the support arms 200b is a high support arm 200b, which fixes the high part of the wheel; the other is a low support arm 200b, which fixes the side of the wheel and prevents the wheel from moving longitudinally.

[0041] In one alternative implementation, such as Figure 7 and Figure 8 As shown, the wheel fixing mechanism 20 further includes a wheel strap assembly 201, which includes a strap disc 201a and a one-way locking strap 201b. The strap disc 201a is mounted on the sliding guide groove 21. One end of the one-way locking strap 201b is fixed to the strap disc 201a, and the other end is used to pass through the one-way locking structure 201c of the strap disc 201a. The portion of the one-way locking strap 201b located between the strap disc 201a and the one-way locking structure 201c is used to fix the wheel. This embodiment adds a wheel strap assembly 201 to the wheel frame assembly 200 to provide a more reliable fixing effect.

[0042] Optionally, the strap disc 201a is fixed to the side or top surface of the guide rail by means of a butterfly bolt 201d or a snap-fit ​​connection. One end of the one-way locking strap 201b is fixed to the strap disc 201a, and the other end is a free end, which is used to wrap around the bicycle wheel 3 and then pass into the one-way locking structure 201c on the strap disc 201a.

[0043] The one-way locking structure 201c can be a ratchet, rack, or friction one-way locking mechanism, allowing the one-way locking strap 201b to pass freely in the tightening direction, but automatically locking in the opposite direction (loosening direction) to prevent loosening. In use, the user wraps the one-way locking strap 201b around the bicycle wheel (usually the rim and tire), pulls the free end taut, and the one-way locking strap 201b secures the wheel to the strap reel 201a or wheel frame assembly 200. The one-way locking structure 201c automatically locks, achieving quick and reliable fastening. For disassembly, the user can release the one-way lock by pressing the release button 201e or moving the unlocking lever, and then remove the one-way locking strap.

[0044] The wheel strap assembly 201 works in conjunction with the wheel frame assembly 200 to form a combined fixation for the wheel: such as Figure 3 As shown, the wheel strap assembly 201 is used to fix the front wheel 30, and the wheel frame assembly 200 is used to fix the rear wheel 31. The double fixation ensures that the bicycle 3 will not shake or fall off due to vibration or bumps during the vehicle's operation, thus improving transportation safety.

[0045] In an optional embodiment, at least one of the fixed openings on the fixed assembly 11 for accommodating the rear bumper 100 and / or the outer edge of the rear bumper 100 is provided with a sealing strip and / or a decorative cover; when the movable assembly 10 moves back to the fixed assembly 11, the sealing strip and / or the decorative cover fills the space between the fixed opening and the outer edge. When the movable assembly 10 moves back into the fixed assembly 11, a gap is formed between the outer edge of the movable assembly 10 and the edge of the fixed opening. A sealing strip can be provided at the edge of the fixed opening, and / or a decorative cover can be provided at the outer edge of the movable assembly 10 to fill the gap. The sealing strip is typically made of flexible materials such as rubber, silicone, or thermoplastic elastomers, and is elastic. When the movable assembly 10 moves back, the sealing strip is compressed and fills the gap, providing waterproofing, dustproofing, and shockproofing, preventing rainwater, dust, or mud from entering the rear bumper interior, and protecting the internal bracket assembly 2 and sliding mechanism. The decorative cover can be made of a hard material that is the same color or texture as the body, covering the outside of the gap, so that the rear bumper assembly 1 presents a complete and continuous appearance after the movable component 10 is moved back, enhancing the overall aesthetics of the vehicle.

[0046] Optionally, the sealing strip is fixed to the edge of the fixed opening by means of a groove, adhesive or pressing; the decorative cover is fixed to the outer edge of the movable component 10 by means of a snap, bolt or adhesive.

[0047] In an optional embodiment, a locking ejection mechanism is further included. This locking ejection mechanism is disposed between the fixed component 11 and the movable component 10, and is used to lock the movable component 10 when it moves back into the fixed component 11, and to unlock and eject the movable component 10 when it is pressed towards the interior of the vehicle body. This embodiment of the application implements a press-type locking and unlocking mechanism for the movable component 10, improving the convenience and intelligence of operation. The locking ejection mechanism can be similar to the press-type locking mechanism of a car glove box.

[0048] In one optional specific embodiment, the locking ejection mechanism includes a locking element, a locking catch, and an ejection elastic element. The locking element is disposed on the fixed component 11 and may be a pivotable pawl; the locking catch is disposed on the movable component 10 and may be a striking pin that cooperates with the pawl; the ejection elastic element (such as a compression spring or torsion spring) is disposed between the fixed component 11 and the movable component 10, and always applies a rearward ejection force to the movable component 10. When the user moves the movable component 10 back into the fixed component 11, the striking pin pushes the pawl to rotate against the spring force. After the striking pin passes the locking hook of the pawl, the pawl rotates back under the action of the return spring, causing the locking hook to hook the striking pin, thus locking. At this time, the ejection elastic element is in a compressed and energy-storing state. When the user needs to use the bracket again, he only needs to gently press the movable component 10 (towards the interior of the vehicle body). The striking pin pushes the pawl to rotate again, causing the locking hook to release the striking pin. The ejection elastic element releases energy instantaneously, ejecting the movable component 10 a certain distance, making it easy for the user to pull out.

[0049] This push-to-lock eject mechanism is simple to operate and offers a clear tactile feedback. Users can lock or unlock with a single press, eliminating the need for additional handles or buttons and maintaining the clean look of the rear bumper. Simultaneously, the ejector spring provides sufficient force to ensure the movable component 10 automatically extends to a comfortable grip position, enhancing the user experience.

[0050] In an optional embodiment, a driving state locking mechanism is further included. This mechanism prevents the movable component 10 from moving outward from the fixed component 11 during vehicle operation. The driving state locking mechanism includes a locking actuator, a vehicle speed sensor, and a controller. The locking actuator is positioned between the fixed component 11 and the movable component 10, and has locked and unlocked states. The vehicle speed sensor acquires and monitors the vehicle's real-time speed signal and sends it to the controller. The controller is electrically connected to the vehicle speed sensor and the locking actuator. The controller has a preset threshold for vehicle speed (e.g., 5 km / h or 10 km / h). When the real-time speed signal exceeds this preset threshold, the controller determines that the vehicle is in motion and sends a locking command to the locking actuator, controlling the actuator to switch to the locked state to restrict the movable component 10 from sliding relative to the fixed component 11. In the locked state, even if the movable component 10 is subjected to a pressing operation towards the interior of the vehicle body or receives a control command to move it electrically, the movable component 10 remains locked within the fixed component 11. This embodiment of the application implements an automatic locking mechanism linked to vehicle speed, achieving a "locking while driving" safety logic. This prevents the moving component 10 from accidentally popping out during vehicle operation due to misoperation or mechanical failure, thus improving vehicle driving safety. The controller in this embodiment can be an independent control unit or integrated into the vehicle's vehicle control unit (VCU), communicating with the vehicle speed sensor via a CAN bus.

[0051] Furthermore, the locking actuator can include electromagnetic locking type, motor-driven type, etc. The electromagnetic locking type includes an electromagnet and a locking pin. When the electromagnet is energized, it drives the locking pin to extend and insert into the locking hole on the movable component 10, thus achieving locking. The motor-driven type includes a micro motor and a transmission mechanism. The rotation of the motor drives the locking pin or locking block to move, thus achieving locking and unlocking.

[0052] When the vehicle speed drops below a preset threshold (such as when the vehicle stops or is parked), the controller controls the locking actuator to switch to the unlocked state, releasing the restriction on the active component 10, and the user can use the bracket function normally.

[0053] In an optional embodiment, the bicycle rack assembly located on the vehicle further includes an anti-sway stabilizing outrigger assembly, which includes a support rod, a height adjustment mechanism, and a grounding pad. The upper end of the support rod is rotatably connected to the bottom rear end of the movable assembly 10 via a hinged bracket (i.e., located on the side furthest from the vehicle body when the movable assembly 10 is fully slid out to the working position).

[0054] Specifically, the hinged support is disposed between the ends of the two pull-out guide rails 101, or separately disposed below the ends of the two pull-out guide rails 101, to form a double-point support and further improve stability.

[0055] The hinged support is equipped with a damping pivot or a positioning buckle, allowing the support rod to have a retracted position and a supported position. In the retracted position, the support rod flips upward and fits into the inner groove on the bottom surface of the movable component 10, ensuring that the overall outline of the support rod does not exceed the bottom boundary of the movable component 10. At this time, the overall outline of the support rod does not exceed the outer boundary of the movable component 10, ensuring that the movable component 10 can smoothly slide back into the fixed component 11 without interference. In the supported position, the support rod flips downward to a vertical state or a slightly backward tilted state (an angle of 70°-90° with the horizontal plane), with its lower end extending to the ground.

[0056] Furthermore, it also includes a height adjustment mechanism located at the lower part of the support rod. The height adjustment mechanism includes a telescopic inner rod sleeved on the lower end of the support rod and a locking knob (or quick-release handle). The total length of the outrigger is adjusted by changing the extension length of the telescopic inner rod. Alternatively, the height adjustment mechanism adopts a threaded screw structure, and fine adjustment can be achieved by rotating the adjusting nut at the lower end of the support rod to adapt to different ground flatness and height changes of the vehicle suspension system under different loads.

[0057] In an optional embodiment, a lighting and warning module is integrated on the rear bumper 100 of the movable component 10. The lighting and warning module includes: at least one LED taillight connected to the vehicle's existing taillight circuit, used to replace the obscured taillights when the bracket assembly 2 is removed; at least one LED turn signal connected to the vehicle's existing turn signal circuit; at least one LED license plate light for illuminating the license plate on the license plate mounting area 100a; a position sensor for detecting the position of the movable component 10 relative to the fixed component 11; and a controller electrically connected to the position sensor and the lighting and warning module for automatically activating the lighting and warning module when the movable component 10 is detected to be in the removed position. In this embodiment, the controller can be a separate control unit or integrated into the vehicle's vehicle control unit (VCU), communicating with the vehicle speed sensor via a CAN bus.

[0058] Optionally, the lighting and warning module further includes at least one rearward-projecting laser warning line generator for projecting a warning line onto the ground behind the vehicle to alert vehicles approaching from behind.

[0059] This application also provides a vehicle, including a vehicle body and a bicycle rack assembly as described in any of the above embodiments; the rear bumper assembly 1 is located at the rear of the vehicle body. By integrating the bicycle rack assembly into the rear bumper, this application enables the vehicle to carry a bicycle 3 without additional disassembly. When a user needs to carry the bicycle 3, they only need to operate the movable component 10 of the rear bumper (e.g., press to pop it out, manually pull it out) to secure the bicycle 3 using the integrated rack assembly 2; after use, the movable component 10 can be moved back to restore the vehicle's normal appearance and bumper function, solving the problem of inconvenient bicycle carrying in the prior art, greatly expanding the vehicle's usage scenarios, and meeting the growing outdoor travel needs of users.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
