Description

Technical Field

[0001] This utility model relates to the field of vehicle bicycle rack technology, and in particular to a vehicle bicycle rack with a long service life. 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, bicycle brackets generally consist of a mounting frame, a lifting drive mechanism, and a support frame for placing the bicycle. The lifting drive mechanism typically drives a connecting rod to rotate via a drive device. This connecting rod is then connected to the support frame, which in turn drives the support frame to rotate. However, the connecting rod is usually a straight rod. When supporting the support frame, it bears excessive reaction pressure, which can affect its lifespan and thus the overall lifespan of the bicycle bracket. Utility Model Content

[0004] This invention provides a long-lasting bicycle mount that reduces the reaction pressure on the connecting rod (arc rod), ensuring its service life, and also makes the lifting and lowering of the bicycle on the support frame more stable.

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

[0006] A bicycle mount includes a mounting frame, a rotating frame, a linear drive mechanism, and a support frame;

[0007] The aforementioned support frame is equipped with at least one fixing bracket for securing the bicycle;

[0008] The aforementioned mounting bracket is used for connection with a vehicle. One end of the aforementioned rotating bracket is rotatably mounted on the aforementioned mounting bracket, and the other end of the aforementioned rotating bracket is rotatably connected to the aforementioned support bracket.

[0009] The linear drive mechanism is rotatably mounted on the mounting frame, and the output shaft of the linear drive mechanism is rotatably connected to the rotating frame, so that the rotating frame rotates relative to the mounting frame and causes the support frame to move up and down.

[0010] The aforementioned rotating frame includes an arc-shaped rod and two rotating rods located below the arc-shaped rod. The two rotating rods are arranged in parallel and connected by a first connecting rod.

[0011] The lower end of the aforementioned arc-shaped rod is rotatably connected to the aforementioned mounting bracket, and the upper end is rotatably connected to the aforementioned support bracket;

[0012] The lower end of the aforementioned rotating rod is rotatably connected to the aforementioned mounting bracket, and the upper end is rotatably connected to the aforementioned support bracket;

[0013] The lowest point of the aforementioned arc-shaped rod is located in the middle of the aforementioned arc-shaped rod, and the output shaft of the aforementioned linear drive mechanism is rotatably connected to the middle of the aforementioned arc-shaped rod.

[0014] Preferably, the mounting bracket includes a cantilever and two parallel triangular frames, the two triangular frames being vertically arranged on the side wall away from the support frame and connected to a mounting plate, and the cantilever being connected to the mounting plate.

[0015] A second connecting rod is provided between the upper ends of the two tripods away from the support frame, and the lower end of the arc-shaped rod is rotatably connected to the second connecting rod.

[0016] The lower ends of the two aforementioned rotating rods are respectively rotatably mounted on the lower ends of the two aforementioned tripods near the aforementioned support frame.

[0017] Preferably, a third connecting rod is provided between the lower ends of the two tripods away from the support frame, and the linear drive mechanism is located between the two tripods and rotatably mounted on the third connecting rod.

[0018] Preferably, the support frame is provided with an L-shaped connecting rod on the side wall near the rotating frame, the L-shaped connecting rod is vertically arranged, and a fourth connecting rod is provided at the lower end of the L-shaped connecting rod;

[0019] The upper end of the aforementioned arc-shaped rod is rotatably connected to the upper end of the aforementioned L-shaped connecting rod, and the upper ends of the two aforementioned rotating rods are respectively rotatably connected to the two ends of the aforementioned fourth connecting rod, with the two rotating connection points located on both sides of the aforementioned L-shaped connecting rod.

[0020] Preferably, the included angle formed on the aforementioned arc-shaped rod is an obtuse angle and less than 160 degrees.

[0021] Preferably, the cantilever is hollow and has multiple connection holes along its length.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] 1. The arc-shaped rod is rotatably connected to the linear drive device and to the support frame, enabling the support frame to be raised and lowered.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] like Figures 1-6 As shown, this utility model embodiment provides a long-life bicycle mount, including a mounting frame 1, a rotating frame 2, a linear drive mechanism 3, and a support frame 4. The support frame 4 has at least one fixed frame 5 for securing bicycles. Generally, two fixed frames 5 are provided to secure two bicycles. When a bicycle is placed horizontally on the fixed frame 5, it will not exceed the width of the car. The mounting frame 1 is used to connect to the car. One end of the rotating frame 2 is rotatably mounted on the mounting frame 1, and the other end is rotatably connected to the support frame 4. The linear drive mechanism 3 is rotatably mounted on the mounting frame 1, and its output shaft is rotatably connected to the rotating frame 2, allowing the rotating frame 2 to rotate relative to the mounting frame 1 and causing the support frame 4 to move up and down. This allows the support frame 4 to be lowered to a certain height when loading or unloading bicycles. After loading the bicycles, the support frame 4 is raised to a certain height through the cooperation of the linear drive mechanism 3 and the rotating frame 2, resulting in the support frame 4 being suspended in a high position. It should be noted that the lifting height of the support frame 4 can be determined by the user by controlling the stroke of the linear drive mechanism 3.

[0038] Specifically, to further ensure the support stability of the support frame 4, in this embodiment, the rotating frame 2 includes an arc-shaped rod 21 and two rotating rods 22 located below the arc-shaped rod 21. The lower end of the arc-shaped rod 21 is rotatably connected to the mounting frame 1, and the upper end is rotatably connected to the support frame 4. The output shaft of the linear drive mechanism 3 is connected to the middle of the arc-shaped rod 21. The two rotating rods 22 are arranged in parallel and connected by a first connecting rod 23. The lower end of the rotating rod 22 is rotatably connected to the mounting frame 1, and the upper end is rotatably connected to the support frame 4. The first connecting rod 23 enables the two rotating rods 22 to form a support frame. On the one hand, it strengthens the support connection effect of the rotating rods 22 on the support frame 4. On the other hand, its connection point with the support frame 4 is located below the connection point between the arc-shaped rod 21 and the support frame 4, forming two rotation support points to keep the support frame 4 stable in the vertical direction. Specifically, the extension or shortening of the output shaft of the linear drive mechanism 3 can cause the arc-shaped rod 21 and the support frame to rotate upward or downward simultaneously, which will drive the entire support frame 4 to move stably upward or downward. Specifically, the linear drive mechanism 3 can be an existing electric actuator.

[0039] Furthermore, as the name suggests, the arc-shaped rod 21 is designed to be arc-shaped. In this embodiment, the lowest point of the arc-shaped rod 21 is located in the middle of the arc-shaped rod 21. It can be seen that the arc-shaped rod 21 bends downward at an angle. The angle between the upper end of the arc-shaped rod 21 and the support frame 4 is smaller than that of the straight rod, thus the vertical component of the force on the support frame 4 is greater, and the support connection capability is better.

[0040] Furthermore, the included angle formed on the arc-shaped rod 21 is an obtuse angle and less than 160 degrees. The larger the angle, the larger the angle between the upper end of the arc-shaped rod 21 and the support frame 4. Thus, the load-bearing capacity of the part of the arc-shaped rod 21 closest to the support frame 4 is greater, which makes the torque of the linear drive mechanism 3 greater. By limiting the included angle formed by the arc-shaped rod 21, the service life of the linear drive mechanism 3 and the arc-shaped rod 21 can be guaranteed.

[0041] Specifically, the mounting frame 1 includes a cantilever 11 and two parallel tripods 12. The tripods 12 are structurally stable, and the two tripods 12 are vertically arranged near the side wall of the end of the cantilever 11 and connected to a mounting plate 13. The cantilever 11 is connected to the mounting plate 13, which makes the installation of the cantilever 11 more stable and also makes the two tripods 12 a whole. Correspondingly, a second connecting rod 14 is provided between the upper ends of the two tripods 12 away from the support frame 4. The lower end of the arc-shaped rod 21 is rotatably connected to the second connecting rod 14. A third connecting rod is provided between the lower ends of the two tripods 12 away from the support frame 4. The linear drive mechanism 3 is located between the two tripods 12 and is rotatably mounted on the third connecting rod. The lower ends of the two rotating rods 22 are respectively rotatably mounted at the lower ends of the two tripods 12 near the support frame 4 and are located on the outside of the two tripods 12, thereby forming a stable support structure.

[0042] Specifically, the linear drive mechanism 3 is located between the two tripods 12 and is rotatably mounted on the third connecting rod, so that the linear drive mechanism 3 is located in the middle of the rotating frame 2, making its center of gravity stable, and the rotation of the linear drive mechanism 3 and the entire rotating frame 2 is more stable.

[0043] Specifically, the support frame 4 is provided with an L-shaped connecting rod 6 on the side wall near the rotating frame 2. The L-shaped connecting rod 6 is set vertically, and the lower end of the L-shaped connecting rod 6 is provided with a fourth connecting rod 61. The upper end of the arc-shaped rod 21 is rotatably connected to the upper end of the L-shaped connecting rod 6. The upper ends of the two rotating rods 22 are respectively rotatably connected to the two ends of the fourth connecting rod 61, and the two rotating connection points are respectively located on both sides of the L-shaped connecting rod 6, so that there are two support points at the second location. This forms a triangular support connection structure with the support points of the upper arc-shaped rod 21 and the L-shaped connecting rod 6, making the connection and support of the entire rotating frame 2 to the support frame 4 more stable.

[0044] 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.

[0045] Of course, in order not to obscure the license plate, a license plate mounting plate 13 is provided at the lower end of the support frame 4, or the inner cantilever 11 of the mounting frame 1 is installed below, above or parallel to the license plate, so that when the support frame 4 is raised, the rotating frame 2, the linear drive mechanism 3 and the mounting frame 1 will not obscure the license plate.

[0046] Preferably, the support frame 4 is foldable. Specifically, the support frame 4 includes a central support rod 41 arranged vertically and side support rods 42 located on both sides of the central support rod 41 and arranged vertically. A bicycle mounting bracket 5 is installed on the upper end of both the central support rod 41 and the support rod. To accommodate at least three bicycles, there are at least two side support rods 42 on each side of the central support rod 41. Adjacent side support rods 42 and the side support rods 42 are connected to the central support rod 41 to form a single unit, allowing the support frame 4 to accommodate at least three bicycles at a time. The mounting bracket 5 is a conventional bicycle mounting bracket 5, and the fixing method is also conventional, and will not be described further.

[0047] Furthermore, to ensure that after the entire support frame 4 is loaded with a bicycle, the connecting parts between the two adjacent side support rods 42 and the middle support rod 41 are all X-shaped connecting frames 43, and the X-shaped connecting frames 43 can be folded, thereby allowing the two adjacent side support rods 42 to move closer together and the side support rod 42 to move closer to the middle support rod 41. Specifically, during loading and unloading of the bicycle, the rotating support frame 2 rotates downward under the drive of the linear drive mechanism 3, causing the support frame 4 and the fixing frame 5 to descend to a height where the user can place the bicycle, and then the X-shaped connecting frames 43 are unfolded. This arrangement increases the distance between adjacent mounting brackets 5, making it easier for users to load or unload bicycles onto or from the support bracket 4 without being affected by bicycles on adjacent sides. Similarly, after the bicycles are loaded, the X-shaped connecting bracket 43 is folded, bringing adjacent side support rods 42 and the middle support rod 41 closer together, i.e., adjacent mounting brackets 5 are close together. This allows adjacent bicycles to be close together, reducing the lateral dimension of the support bracket 4 so that it does not extend beyond the outside of the car and does not affect other vehicles while the car is in motion. It should be noted that in order for the two bicycles to be closer together after the support bracket 4 is folded, and for the bicycle handlebars not to hinder the further approach of the two bicycles, the bicycles on adjacent mounting brackets 5 are staggered. This staggered placement is achieved by the user during placement.

[0048] Specifically, the central support rod 41 includes a connecting central rod 412 and side central rods 411 connected to both sides of the connecting central rod 412. The side central rods 411 are used to install the X-shaped connecting frame 43, and the connecting central rod 412 is used to install the fixing frame 5. Moreover, the L-shaped connecting rod 6 connected to the rotating frame 2 is connected to the connecting central rod 412, so that the connection with the rotating rod 22 and the connection with the X-shaped connecting frame 43 both act on the connecting central rod 412, thereby improving the overall strength of the central support rod 41 that bears the connection relationship. In this embodiment, an X-shaped connecting frame 43 connects the side center rod 411 and the adjacent side support rod 42. Specifically, a sliding tube 44 is fitted onto each side support rod 42 and each side center rod 411. The two upper connecting ends of the X-shaped connecting frame 43 between two adjacent side support rods 42 are rotatably connected to connecting blocks provided on the upper parts of the two side support rods 42, and the two lower connecting ends of the X-shaped connecting frame 43 are rotatably connected to connecting blocks provided on the lower parts of the two side support rods 42. Similarly, on the sliding tube 44, the two connecting ends of the upper part of the X-shaped connecting frame 43 between the side center rod 411 and the adjacent side support rod 42 are rotatably connected to the connecting blocks set on the upper part of the side center rod 411 and the side support rod 42, respectively. The two connecting ends of the lower part of the X-shaped connecting frame 43 are rotatably connected to the sliding tube 44 set on the upper part of the side center rod 411 and the side support rod 42, respectively. Moreover, the lower ends of the X-shaped connecting frames 43 on both sides of the same side support rod 42 are connected to the same sliding tube 44, thereby enabling the stable folding and unfolding of the entire support frame 4.

[0049] Furthermore, a fixing through hole is provided on the outermost sliding tube 44, and a threaded hole is provided on the outermost side support rod 42. After the bicycle is loaded, the X-type connecting frame 43 is in a folded state. A bolt can be passed through the fixing hole and connected to the threaded hole to lock the folded state of the X-type connecting frame 43, so that the folded state of the entire support frame 4 is locked and will not unfold on its own.
