Description

Technical Field

[0001] This invention relates to a bicycle frame, and more particularly to a vehicle-mounted electric telescopic bicycle frame. Background Technology

[0002] As the automotive industry undergoes a profound transformation towards intelligent and electrified transportation, the role of the car has gradually evolved from a simple means of transportation to a "third space" integrating travel, living, and entertainment. Under this trend, the human-centered design, comfort, and convenience of various components within the cabin have become fundamental and crucial elements. This pursuit of the ultimate user experience will inevitably extend to the vehicle's external functions and accessories; the convenient user experience of in-vehicle electric bicycle racks will be a growing trend.

[0003] Currently, the mainstream bicycle racks on the market mainly include tow racks, roof racks, and trunk / tailgate-mounted racks. Tow racks typically require dedicated tow hooks (square / ball-end), making installation complex, requiring specific vehicle modifications, and resulting in higher costs. The racks themselves are bulky and inconvenient to store; they also obstruct license plates and taillights, necessitating additional license plate holders and lighting devices to meet regulations, further increasing complexity. Roof racks require lifting the bicycle onto the roof, a process demanding significant physical strength (especially for women and the elderly), posing safety hazards, and are limited by garage height. They also increase wind resistance and noise, reducing fuel economy or increasing energy consumption for electric vehicles. Trunk / tailgate-mounted racks usually rely on straps or hooks to secure to the tailgate / bumper, resulting in poor stability and potential damage to the paint. Opening the trunk usually requires disassembling the rack, which is extremely cumbersome, involves frequent loading and unloading, and offers a disjointed user experience.

[0004] In summary, existing bicycle racks generally suffer from core pain points such as "laborious installation, inconvenient retrieval and placement, impact on basic vehicle functions, and poor user experience". Summary of the Invention

Detailed Implementation

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] Embodiments of the present invention: such as Figures 1-4 As shown, a vehicle-mounted electric telescopic bicycle rack includes a storage frame, a bicycle support assembly, a slide rail assembly, and a position adjustment assembly. The storage frame is fixed to the bottom surface at the rear end of the chassis. The bicycle support assembly is movably mounted on the storage frame via the slide rail assembly. The bicycle support assembly is connected to the storage frame via the position adjustment assembly.

[0023] The bicycle support assembly has two working positions, namely a first working position and a second working position. A position adjustment component is used to drive the bicycle support assembly to switch between the first and second working positions. When in the first working position, the bicycle support assembly is located inside the storage frame and is retracted to the bottom of the vehicle. When in the second working position, the bicycle support assembly extends out of the storage frame and the rear of the vehicle, at which point the bicycle can be secured to the bicycle support assembly.

[0024] This invention uses electric adjustment, eliminating the need for manual disassembly and assembly of bicycle support components, effectively saving manpower.

[0025] Specifically, the storage frame includes a base plate 1, a left side plate 2, and a right side plate 3. The left side plate 2 is fixed to the left side of the base plate 1, and the right side plate 3 is fixed to the right side of the base plate 1. A groove 26 is formed in the middle of the base plate 1. The groove 26 extends along the length of the vehicle, and a screw rod mounting seat 4 is fixed at the end of the groove 26 near the front of the vehicle.

[0026] In order to reduce the overall weight of this product and improve fuel economy and energy consumption of electric vehicles, it is preferable to open a large number of weight reduction holes on the base plate 1, left side plate 2 and right side plate 3 while ensuring structural strength.

[0027] The top of the left side plate 2 and the right side plate 3 are respectively provided with three connecting lugs 27, which are fixed to the vehicle chassis by bolt assemblies.

[0028] The position adjustment assembly includes a lead screw 5 and a through lead screw motor 6. One end of the lead screw 5 is fixedly connected to the lead screw mounting base 4, and the other end of the lead screw 5 is connected to the through lead screw motor 6. Both the lead screw 5 and the through lead screw motor 6 are located in the groove 26.

[0029] By providing a recess 26 to accommodate the lead screw 5 and the through lead screw motor 6, the height of the left side plate 2 and the right side plate 3 can be reduced, saving both material and weight. The through lead screw motor 6 is a commercially available product and can be purchased directly. Those skilled in the art will understand that the vehicle interior will necessarily have control buttons for controlling the forward and reverse rotation of the through lead screw motor 6.

[0030] Furthermore, the bicycle support assembly includes a bicycle support frame 7, wheel holders 8, a first pedal holder and a second pedal holder. Two wheel holders 8 are rotatably mounted on the left and right beams of the bicycle support frame 7, respectively. The two wheel holders 8 on the left beam are distributed opposite to the wheel holders 8 on the right beam, and the wheel holders 8 can be rotated 180°.

[0031] By setting four wheel fixing brackets 8, two bicycles can be placed and fixed at the same time. The four wheel fixing brackets 8 have the same structure. A wheel limiting protrusion 28 is formed on the top surface of the bracket to limit the bicycle tire. A tire limiting groove 29 is formed on the top surface of the wheel limiting protrusion 28. A strap 30 is also provided on the wheel limiting protrusion 28. The wheel limiting protrusion 28 on the left beam is set in the opposite direction to the wheel limiting protrusion 28 on the right beam. This can effectively prevent the bicycle from swaying from side to side.

[0032] A motor mounting plate 9 is fixed on the end plate near the front of the bicycle support frame 7. A through-screw motor 6 is fixedly mounted on the motor mounting plate 9. A crash beam 10 is fixed on the end plate near the rear of the bicycle support frame 7. A brake light 25 is installed on the crash beam 10. A license plate frame 11 is rotatably mounted on the top of the end plate.

[0033] The anti-collision beam 10 effectively prevents impacts and, when reversing, prevents damage to the bicycle due to improper distance control. The brake light 25 is electrically connected to the rear brake light of the vehicle. The arrangement of the brake light 25 and the license plate frame 11 ensures that this product does not affect the basic functions of the vehicle during use, thus improving safety.

[0034] Furthermore, a crossbeam 12 is fixed on the bicycle support frame 7, and a first mounting seat 16 and a second mounting seat 17 are fixed on the crossbeam 12. The first pedal fixing frame includes a first vertical rod 13, a first support rod 14, and a first U-shaped pedal limiting frame 15. One end of the first vertical rod 13 is rotatably mounted on the first mounting seat 16 via a pivot, and the other end of the first vertical rod 13 is rotatably connected to one end of the first support rod 14 via a pivot. The first U-shaped pedal limiting frame 15 is fixed to the other end of the first support rod 14.

[0035] The second pedal fixing frame includes a second vertical rod 18, a second support rod 19, and a second U-shaped pedal limiting frame 20. One end of the second vertical rod 18 is rotatably mounted on the second mounting base 17 via a pivot, and the other end of the second vertical rod 18 is rotatably connected to one end of the second support rod 19 via a pivot. The second U-shaped pedal limiting frame 20 is fixed to the other end of the second support rod 19. The length of the second vertical rod 18 is less than the length of the first vertical rod 13.

[0036] Furthermore, the slide rail assembly includes two first slide rails 21 and two second slide rails 22. Two first sliders 23 are fixed on the inner sides of the left side plate 2 and the right side plate 3, respectively. The two first slide rails 21 are respectively mounted on the left side plate 2 and the right side plate 3 through the first sliders 23. Two second sliders 24 are fixed on the inner sides of the two first slide rails 21, respectively. One second slide rail 22 is fixed on the left beam and the right beam of the bicycle support frame 7, respectively. The two first slide rails 21 are respectively connected to the two second slide rails 22 through the two second sliders 24.

[0037] By setting the first slide rail 21 and the second slide rail 22, the bicycle support assembly can extend a greater distance.

[0038] The working principle of this invention is as follows: When in use, pressing the control button starts the through-screw motor 6. Through the cooperation of the through-screw motor 6 and the lead screw 5, the through-screw motor 6 moves towards the rear of the bicycle. The through-screw motor 6 pushes the bicycle support frame 7 to move via the motor mounting plate 9. The bicycle support frame 7 moves from the first working position to the second working position. When the bicycle support frame 7 moves to the second working position, pressing the stop button stops the through-screw motor 6. Automatic stopping can also be achieved by setting a position switch at an appropriate location. At this time, the product is in the following state: Figure 4 As shown.

[0039] Manually flip the license plate holder 11 from a horizontal position to a vertical position, then flip the first vertical bar 13 and the second vertical bar 18 to a vertical position, then flip the four wheel fixing brackets 8 by 180° respectively, so that all four wheel fixing brackets 8 are flipped to the outside of the bicycle support frame 7, then flip the first vertical bar 13 and the second vertical bar 18 to a horizontal position, and flip the first support bar 14 and the second support bar 19 to a vertical position. At this time, the bicycle can be moved onto the bicycle support frame 7. Use the two wheel limiting bosses 28 to limit the front wheel and the rear wheel of the bicycle, then use the straps 30 to fix the wheels, and finally insert the bicycle pedals into the first U-shaped pedal limiting frame 15.

[0040] When not in use, manually reset the wheel holder 8, license plate holder 11, first longitudinal bar 13, first support bar 14, second longitudinal bar 18 and second support bar 19, and then press the control button to retract the bicycle support assembly into the storage frame.

[0041] The above description, based on the embodiments shown in the figures, details the structure, features, and effects of the present invention. The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, that do not exceed the spirit covered by the specification and figures, should be within the protection scope of the present invention.
