Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted bicycle rack technology, and in particular to a foldable vehicle-mounted bicycle rack. Background Technology

[0002] As living standards improve, people are paying more and more attention to environmentally friendly travel or exercise. Some cycling enthusiasts often drive (here, "vehicle" refers to medium and large vehicles that are allowed to carry bicycles at the rear without violating traffic regulations, such as trucks, large SUVs, etc.) to find suitable places to ride and exercise. Therefore, for drivers, bicycle racks at the rear of their vehicles have become a convenient and practical vehicle tool.

[0003] However, the number of bicycles that can be loaded on the rear bicycle rack is currently limited, usually only one or two. If more bicycles need to be loaded, the overall size of the rack needs to be increased, which will affect the car's operation. However, if the size of the rack is controlled to accommodate more bicycles, loading and unloading the bicycles will be inconvenient and time-consuming due to the compact space between the bicycles. Utility Model Content

[0004] This utility model provides a foldable bicycle rack that can carry multiple bicycles. The lateral width of the entire support frame is adjustable. When the car is in motion, the lateral width of the support frame is reduced, making the overall size of the rack smaller and not affecting the car's movement. When loading and unloading bicycles, the lateral width of the support frame is increased, making it easier for the user to load and unload bicycles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable bicycle mount includes a mounting frame, a lifting drive mechanism, and a support frame.

[0007] The aforementioned mounting bracket is used to connect to a vehicle, the aforementioned lifting drive mechanism is connected to the aforementioned mounting bracket, and the other end of the aforementioned lifting drive mechanism is connected to the aforementioned support frame, so that the aforementioned support frame can be raised and lowered in the vertical direction.

A bicycle fixing frame is horizontally installed at the upper end of both the central support rod and the support rod.

[0009] Each side of the aforementioned central support rod has at least two side support rods, and an X-shaped connecting frame is provided between each of the two adjacent side support rods and the aforementioned side support rod and the aforementioned central support rod. The aforementioned X-shaped connecting frame is foldable so that the two adjacent side support rods are close to each other and the aforementioned side support rod is close to the aforementioned central support rod.

[0010] Preferably, the aforementioned support rod includes a connecting central rod and side central rods connected to both sides of the connecting central rod. The side central rods are used to install the aforementioned X-shaped connecting frame, and the connecting central rod is used to install the aforementioned fixing frame.

[0011] The aforementioned lifting drive mechanism is connected to the aforementioned connecting rod.

[0012] Preferably, each of the aforementioned side support rods and each of the aforementioned side middle rods is fitted with a sliding tube, and the two connecting ends of the upper part of the X-shaped connecting frame between two adjacent side support rods are respectively rotatably connected to the connecting blocks provided on the upper part of the two aforementioned side support rods, and the two connecting ends of the lower part of the X-shaped connecting frame are respectively rotatably connected to the sliding tubes provided on the lower part of the two aforementioned side support rods;

[0013] The two connecting ends of the upper part of the X-shaped connecting frame between the aforementioned side center rod and the adjacent side support rod are respectively rotatably connected to the connecting blocks provided on the upper part of the aforementioned side center rod and the aforementioned side support rod. The two connecting ends of the lower part of the X-shaped connecting frame are respectively rotatably connected to the sliding tubes provided on the upper part of the aforementioned side center rod and the aforementioned side support rod. Furthermore, the lower ends of the X-shaped connecting frames on both sides of the same aforementioned side support rod are connected to the same sliding tube.

[0014] Preferably, the two outermost side support rods of the support frame are provided with fixed threaded holes, and the sliding tubes provided thereon are provided with fixed through holes.

[0031] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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 utility model based on the specific circumstances.

[0034] like Figures 1-7 As shown, this utility model embodiment provides a foldable bicycle mount, including a mounting frame 1, a lifting drive mechanism 2, and a support frame 3; wherein the mounting frame 1 is used to connect to a car, the lifting drive mechanism 2 is connected to the mounting frame 1, and the other end of the lifting drive mechanism 2 is connected to the support frame 3, so that the support frame 3 can be lifted and lowered in the vertical direction, and the bicycle is placed on the support frame 3, thereby the bicycle is lifted and lowered under the drive of the lifting drive mechanism 2.

[0035] Specifically, the support frame 3 includes a central support rod 31 arranged vertically and side support rods 32 located on both sides of the central support rod 31 and arranged vertically. Both the central support rod 31 and the upper end of the support rods are equipped with bicycle mounting brackets 4. To accommodate at least three bicycles, there are at least two side support rods 32 on each side of the central support rod 31. Adjacent side support rods 32 and the side support rods 32 are connected to the central support rod 31 to form a single unit, allowing the support frame 3 to accommodate at least three bicycles at a time. The mounting brackets 4 are existing bicycle mounting brackets, and the fixing method is also existing, so it will not be described in detail.

[0036] Furthermore, to ensure that after the entire support frame 3 is loaded with a bicycle, the connecting parts between the two adjacent side support rods 32 and the middle support rod 31 are all X-shaped connecting frames 33, which can be folded to allow the two adjacent side support rods 32 to move closer together and the side support rod 32 to move closer to the middle support rod 31, specifically, during loading and unloading of the bicycle, the support frame rotates downward under the drive of the linear drive device 24, causing the support frame 3 and the fixed frame 4 to descend to a height where the user can place the bicycle, and then the X-shaped connecting frame 33 is unfolded. This increases the distance between adjacent mounting frames 4, making it easier for users to load or unload bicycles onto or from the support frame 3 without being affected by bicycles on the adjacent side. Similarly, after the bicycle is loaded, the X-shaped connecting frame 33 is folded, at which point the two adjacent side support rods 32 are close together and the side support rods 32 are close to the middle support rod 31, that is, the two adjacent mounting frames 4 are close together, thus allowing the two adjacent bicycles to be close together. This reduces the lateral dimension of the support frame 3, preventing it from extending beyond the outside of the car and thus not affecting other vehicles while the car is in motion.

[0037] It is important to know that in order for the two bicycles to be able to come closer together after the support frame 3 is folded, and for the bicycle handlebars not to hinder the two bicycles from getting closer together, the bicycles on the adjacent fixed frames 4 are placed in a staggered manner. This staggered placement is achieved by the user when placing the bicycles, or by setting the two adjacent fixed frames 4 to be staggered in the front-to-back direction, and then placing the bicycles normally on the fixed frames 4, which also achieves the staggered placement of the adjacent bicycles.

[0038] Of course, in order not to obscure the license plate, a license plate mounting plate is provided at the lower end of the support frame 3, or the inner cantilever 11 of the mounting frame 1 is installed below, above or parallel to the license plate, so that the lifting drive mechanism 2 and the mounting frame 1 will not obscure the license plate after the support frame 3 is raised.

[0039] Specifically, the central support rod 31 includes a connecting central rod 312 and side central rods 311 connected to both sides of the connecting central rod 312. The side central rods 311 are used to install X-shaped connecting frames 33, and the connecting central rod 312 is used to install the fixing frame 4. Moreover, the lifting drive mechanism 2 is connected to the connecting central rod 312 to avoid the connection with the lifting drive mechanism 2 and the connection with the X-shaped connecting frame 33 acting on the connecting central rod 312, thereby improving the overall strength of the central support rod 31 bearing the connection relationship. In this embodiment, an X-shaped connecting frame 33 is connected between the side central rod 311 and the adjacent side support rod 32, and an X-shaped connecting frame 33 is connected between two adjacent side support rods 32. Specifically, a sliding tube 34 is sleeved on each side support rod 32 and each side central rod 311. The two connecting ends of the upper part of the X-shaped connecting frame 33 between two adjacent side support rods 32 are respectively rotatably connected to the connecting blocks provided on the upper part of the two side support rods 32, and the two connecting ends of the lower part of the X-shaped connecting frame 33 are respectively rotatably connected to the connecting blocks provided on the lower part of the two side support rods 32. Similarly, on the sliding tube 34, the two connecting ends of the upper part of the X-shaped connecting frame 33 between the side center rod 311 and the adjacent side support rod 32 are rotatably connected to the connecting blocks set on the upper part of the side center rod 311 and the side support rod 32, respectively. The two connecting ends of the lower part of the X-shaped connecting frame 33 are rotatably connected to the sliding tube 34 set on the upper part of the side center rod 311 and the side support rod 32, respectively. Moreover, the lower ends of the X-shaped connecting frames 33 on both sides of the same side support rod 32 are connected to the same sliding tube 34, thereby enabling the stable folding and unfolding of the entire support frame 3.

[0040] Furthermore, the two outermost side support rods 32 of the support frame 3 are provided with fixing threaded holes, and the sliding tubes 34 provided on them are provided with fixing through holes 341. The fixing threaded holes and fixing through holes 341 are used in conjunction. By passing bolts through the fixing through holes 341 and threadedly connecting them to the fixing threaded holes, the sliding tubes 34 are fixed to the side support rods 32. Specifically, after the bicycle is loaded and the X-shaped connecting frame 33 is in a folded state, bolts can be passed through the fixing through holes 341 and connected to the threaded holes to lock the folded state of the X-shaped connecting frame 33, so that the folded state of the entire support frame 3 is locked and will not unfold on its own.

[0041] Specifically, the upper ends of the side support rod 32 and the connecting rod 312 are both connected to a horizontal rod 35. The fixing frame 4 is set on the horizontal rod 35, thereby further strengthening the strength of the entire support frame 3 and stabilizing the horizontal support fixing frame 4 so that the bicycle is level.

[0042] Specifically, the mounting bracket 1 includes a cantilever 11 and two parallel tripods 12. The tripods 12 are structurally stable, and the two tripods 12 are vertically positioned near the sidewall of one end of the cantilever 11 and connected to a mounting plate 13. The cantilever 11 is connected to the mounting plate 13, making the installation of the cantilever 11 more stable and also making the two tripods 12 a single unit. Correspondingly, the linear drive device 24 is rotatably mounted on the fourth connecting rod 51 between the two tripods 12, while the rotating frame is rotatably mounted on the tripods 12. Specifically, the linear drive device 24 can be an existing electric actuator.

[0043] Specifically, the cantilever 11 is hollow, which reduces the weight of the cantilever 11 while ensuring connection strength. In addition, multiple connection holes 111 are provided on the cantilever 11 along its length to facilitate adjustment of the connection position between the cantilever 11 and the vehicle rear mounting point, so as to further meet the user's connection needs.

[0044] Specifically, the lifting drive mechanism 2 includes a rotating frame and a linear drive device 24. One end of the rotating frame is rotatably mounted on a tripod 12 on the mounting frame 1, and the other end of the rotating frame is rotatably connected to the support frame 3. The mounting end of the linear drive device 24 is rotatably mounted between the two tripods 12, and the output shaft of the linear drive device 24 is rotatably connected to the rotating frame. Thus, the linear drive device 24 can drive the rotating frame to rotate relative to the mounting frame 1, thereby causing the rotating frame to move the entire support frame 3 vertically. The bicycle placed on the support frame 3 will also move vertically, stopping after moving a certain distance from the ground. The entire support frame 3 is suspended behind the car, and the maximum height of the bicycle will not exceed the height of the car. Furthermore, it is not necessary to place the bicycle on the roof of the car, leaving space on the roof for loading other items. Specifically, the linear drive device 24 can be an existing push rod motor.

[0045] Specifically, the rotating frame includes an arc-shaped rod 21 and two rotating rods 22 located below the arc-shaped rod 21, with the two rotating rods 22 arranged parallel to each other. A first connecting rod 23 connects the two rotating rods 22 to form a whole, increasing the support strength. Correspondingly, a second connecting rod 14 connects the two tripods 12 away from the upper end of the support frame 3. The lower end of the arc-shaped rod 21 is rotatably connected to the second connecting rod 14, and the upper end is rotatably connected to the middle support rod 31. The lowest point of the arc-shaped rod 21 is located in the middle of the arc-shaped rod 21. The mounting part of the linear drive device 24 is rotatably disposed on a third connecting rod between the two tripods 12, and its output shaft is connected to the arc-shaped rod 21. The middle part of the support frame 3 is rotatably connected. The lower ends of the two rotating rods 22 are rotatably connected to the ends of the two tripods 12 away from the cantilever 11, and the upper ends are rotatably connected to the middle support rod 31. This allows the output shaft of the linear drive device 24 to extend, enabling the arc rod 21 to rotate. The arc rod 21 then drives the entire support frame 3 to move upward. The support frame formed by the two rotating rods 22 and the second connecting rod 14 serves as a connecting support, increasing the connection strength of the entire rotating frame. Furthermore, the connection point between the arc rod 22 and the support frame 3 is located below the connection point between the arc rod 21 and the support frame 3, forming a straight line, which together ensures that the support frame 3 remains stable in the vertical direction. Moreover, the lowest point of the arc rod 21 is located in the middle of the arc rod 21, indicating that the arc rod 21 bends downward. The angle between the end of the arc rod 21 near the support frame 3 and the support frame 3 is smaller, resulting in a larger vertical component force on the support frame 3 and better support connection capability.

[0046] Specifically, an L-shaped connecting rod 5 is provided on the side wall of the middle support rod 31 near the rotating frame. The L-shaped connecting rod 5 is set vertically, and a fourth connecting rod 51 is provided at the lower end of the L-shaped connecting rod 5. Correspondingly, the upper end of the arc-shaped rod 21 is rotatably connected to the upper end of the L-shaped connecting rod 5, and the upper ends of the two rotating rods 22 are respectively rotatably connected to the two ends of the fourth connecting rod 51. The two rotating connection points are located on both sides of the L-shaped connecting rod 5. By adding the L-shaped connecting rod 5, the support capacity of the rotating frame for the support rod can be further increased, so that the support frame 3 can be stably raised and lowered in the vertical direction.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
