Description

Technical Field

[0001] The present invention relates to a bicycle accessory, in particular to a tiltable bicycle carrying frame which can be tilted at an angle for conveniently taking out articles in the bicycle. Background Art

[0002] Generally, when transporting bicycles, a bicycle carrier is used to place the bicycles on the back of the car. In this way, the bicycles do not need to be excessively disassembled during transportation, which can reduce the time of sorting. Figure 1 As shown, an existing bicycle-carrying frame 10 includes a support 11, a frame body 12 and a quick-release unit 13; the support 11 has two clamping parts 111, and the quick-release unit 13 can open or close the clamping parts 111, so that the clamping parts 111 can clamp or loosen a trailer head fixed to the rear of the vehicle, and the frame body 12 is connected to the two clamping parts 111 by two support rods 121, and a bendable connecting rod 122 is provided between the two support rods 121. When generally used, the two clamping parts 111 will be clamped on the trailer head, so the two support rods 121 of the frame body 12 will form an open state, and a bicycle can be carried on the two support rods 121; when the two support rods 121 are opened, the ... trailer head; when the two support rods 121 are opened, the bicycle can be carried on the trailer head; when the two support rods 121 are opened, the bicycle can be carried on the trailer head; when the two support rods 121 are opened, the bicycle can be carried on the trailer head; when After using the support rods 121 or when taking items from the rear seat of the car, it is necessary to press the quick-release unit 13 to separate the support base 11 from the trailer head, that is, to move the two clamping parts 111 away from the trailer head. At the same time, the two support rods 121 on the two clamping parts 111 will move closer to each other inwardly. At the same time, the connecting rod 122 will be bent, so that the two support rods 121 can be retracted, and then the vehicle carrying frame 10 can be separated from the trailer head, allowing the user to open the tailgate or window on the rear side of the car and take items. After completion, the support base 11 is re-fixed to the trailer head and the quick-release unit 13 is pressed to fix it.

[0003] In order to ensure that the support 11 can be firmly fixed to the trailer head during driving, the quick-release unit 13 provides a strong clamping force, so it is relatively difficult to remove the support 11. Moreover, when removing the support 11, if there is still a bicycle on the frame 12, it is necessary to first remove the bicycle and then remove it. After re-fixing the support 11, the bicycle must be re-installed on the frame 12, causing inconvenience in use. Summary of the Invention

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0033] See also Figures 2 to 4 FIG. 1 is a preferred embodiment of a tiltable bicycle carrier provided by the present invention, wherein the bicycle carrier 20 comprises:

[0034] The two bearings 30 are each provided with a bearing groove 31 at a facing position. A straight rod 32 is vertically provided on the two bearings 30. The free ends of the two straight rods 32 are pivotally connected to a connecting portion 33. The connecting portion 33 is a single piece and is pivotally connected to the two straight rods 32 at both ends. The two straight rods 32 can rotate the two bearings 30 respectively using the connecting portion 33 as an axis, so that the two bearings 30 can rotate respectively using the ends of the straight rods 32 as an axis. The front ends of the two bearings 30 are provided with a stop portion 34, and the top of the stop portion 34 is provided with an inclined surface 341.

[0035] Two support rods 40 are each provided with a pivot 41 at one end thereof, pivotally connected to the straight rods 32 of the two bearings 30, and can rotate on the straight rods 31 with the pivot 41 as the axis. The stopper 34 on the two bearings 30 is located at the front end of the two support rods 40, so that the two inclined surfaces 341 can limit the rotation angle of the two support rods 40, thereby preventing the two support rods 40 from rotating too much.

[0036] Two storage rods 50, each having two storage portions 51 thereon. The ends of the two storage rods 50 are pivotally mounted on the free ends of the two rack rods 40 via a quick release unit 60;

[0037] The two quick release units 60, please refer to Figure 3 , respectively include two toothed discs 61, a screw 62, an eccentric rod 63, a spring 64 and a positioning member 65; the two toothed discs 61 are respectively arranged at the end positions of the frame rod 40 and the storage rod 50 and can be meshed and fixed with each other or separated and can rotate freely; the screw 62 is passed through the ends of the two toothed discs 61 and is screwed to the eccentric rod 63, the eccentric rod 63 has a cam 631 and a handle 632, when the handle 632 rotates, it can drive the cam 631 close to or away from the toothed disc 61, thereby making the toothed disc 61 mesh or separate; the spring 64 is arranged between the two toothed discs 61, which can form an elastic thrust. When the two toothed discs 61 are separated, the The spring 64 will push the two toothed discs 61 outward so that the two toothed discs 61 can be separated and the storage rod 50 can be freely adjusted on the rack rod 40; the grip 632 of the eccentric rod 63 is provided with the positioning member 65, which can generate an elastic force in the direction of the toothed disc 61, and a positioning groove 611 is relatively provided on the toothed disc 61. When the positioning member 65 is elastically engaged in the positioning groove 611, the eccentric rod 63 cannot rotate, so that the two toothed discs 61 can maintain their engaged position. When the eccentric rod 63 is to be rotated, the positioning member 65 needs to be pulled to disengage it from the positioning groove 611, thereby allowing the eccentric rod 63 to rotate freely.

[0038] Second fixing unit 70, please refer to Figure 4When the cam 72 is in the closed position, the cam 72 is in the closed position, and the cam 72 is in the closed position, so that the cam 72 is in the closed position and the cam 72 is in the closed position.

[0039] A fixing unit 80, please refer to Figure 4 , the two ends are respectively pivotally mounted on the two frame rods 40, and the position of the forced unit 80 can be adjusted to drive the position of the two frame rods 40, thereby adjusting the opening or closing of the two bearings 30; the forced unit includes two connecting rods 81 and a fixing member 82, one of which is provided with a guide groove 811, and the fixing member 82 is provided with a guide rod 821 in the guide groove 811, so that the guide rod 821 can be slidably mounted in the guide groove 811, and the fixing member 82 can slide on the connecting rod 81; one end of the two connecting rods 81 is divided into The two connecting rods 81 are pivotally connected to the frame rod 40 at their other ends, and are pivotally connected to each other at the other ends. When the two frame rods 40 are pressed inward, the pivotal positions of the two connecting rods 81 will face upward, and at the same time, the positions of the receiving grooves 31 of the two bearing seats 30 will open. When the two frame rods 40 are pushed outward, the two connecting rods 81 can be arranged in a straight line. At this time, the fixing member 82 can be placed across the two connecting rods 81 to prevent the two connecting rods 81 from bending and deforming. At the same time, the two frame rods 40 can concentrate the two receiving grooves 31 of the two bearing seats 30 to perform a clamping and fixing action. In order to enable the fixing member 82 to automatically span the two connecting rods 81 after the two connecting rods 81 form a straight line, an elastic element 83 is provided between the fixing member 82 and the two connecting rods 81. One end of the elastic element 83 is fixed to the pivot position of the two connecting rods 81, and the other end is fixed to the guide rod 821 of the fixing member 82. When the fixing member 82 moves away from the pivot position of the two connecting rods 81, the elastic element 83 generates an elastic restoring force. When the two connecting rods 81 form a straight line, the elastic restoring force of the elastic element 83 causes the fixing member 82 to move toward the pivot position of the two connecting rods 81. Because the guide rod 821 is limited by the guide groove 811, the fixing member 82 will slide horizontally on the two connecting rods 81, so that the fixing member 82 can automatically span between the two connecting rods 81.

[0040] The two belt bodies 90 are arranged at the center of the two frame rods 40, roughly corresponding to the position of the fastening unit 80. The two belt bodies 90 can help fix the vehicle to prevent the vehicle frame 20 from falling off.

[0041] When using, please refer to Figure 5 As shown, when the vehicle-carrying frame 20 is installed on a vehicle, the upper ends of the two frame bars 40 are first folded inwardly with the position of the forcing unit 80 as the axis point, so that the two connecting rods 81 of the forcing unit 80 form a concave state, thereby reducing the distance between the upper ends of the two frame bars 40. The lower ends of the two frame bars 40 near the support 30 will expand outward relative to each other, thereby causing the support 30 to expand outward with the connecting portion 33 as the axis, thereby increasing the distance between the two support grooves 31, so that it can be placed outside a trailer head T.

[0042] When the position of the support 30 is fixed, please refer to Figure 4 and Figure 5 , the upper ends of the two frame rods 40 are pushed outward, so that the two connecting rods 81 of the forced fixing unit 80 gradually become straight. At the same time, the lower ends of the two frame rods 40 will drive the support 30 to retract inward. When the two connecting rods 81 become a straight state, the support groove 31 can completely clamp the trailer head. At the same time, the elastic element 83 on the forced fixing unit 80 will generate an elastic pulling force on the fixing member 82, so that the fixing member 82 can slide toward the pivot position of the two connecting rods 81 and fix the position of the two connecting rods 81, and also keep the position of the two support seats 30 fixed, so that the two support grooves 31 can hold the trailer head T. In order to ensure that the vehicle carrying frame 20 does not fall off, the two belt bodies 90 can be tied around the car to strengthen the fixation.

[0043] Please refer to Figure 6 The two storage rods 50 can be adjusted relative to the two rack rods 40. To adjust the angle of the two storage rods 50, the quick release unit 60 is first pulled to rotate the cam 631 on the eccentric rod 63 away from the two gear plates 61. The spring 64 generates an elastic force to separate the two gear plates 61, allowing the two storage rods 50 to adjust their angles on the two rack rods 40. After the adjustment is completed, the eccentric rod 63 is rotated to move the cam 631 toward the two gear plates 61. In this way, the two gear plates 61 are engaged with each other, and the relative positions of the two storage rods 50 and the two rack rods 40 are fixed. At the same time, the positioning member 65 is relatively engaged in the positioning groove 611, so that the positioning member 65 and the handle 632 of the eccentric rod 63 are fixed in position, thereby maintaining the positions of the two storage rods 50 and the two rack rods 40. When the two storage rods 50 are fixed, bicycles can be placed on the storage portions 51 and fixed. When bicycles are not placed, the two storage rods 50 can be folded to the sides of the two rack bars 40.

[0044] When you need to get items from your vehicle, refer to Figure 7 As shown, by pulling the pull rods 71 ​​of the two fixing units 70, the two pull rods 71 ​​can be disengaged from the two connecting grooves 72, that is, the two frame rods 40 can rotate freely around the pivot 41. At this time, the two frame rods 40 are rotated around the position of the pivot 41 pivotally connected to the straight rod 32, so that the two frame rods 40 and the two storage rods 50 can be rotated away from the car at the same time, thereby forming a larger operating space between the car carrying frame 20 and the car, making it easy to take items in the car without having to disassemble the car carrying frame 20. The rotation angle of the two support rods 40 is also affected by the stoppers 34 on the two bearings 30, causing the two support rods 40 to press against the inclined surfaces 341 of the two stoppers 34, preventing further downward rotation. This prevents the two support rods 40 from rotating excessively. Furthermore, the two support rods 40 are held in place by the stoppers 34, eliminating the need for manual gripping and allowing the user to operate the two support rods 40 independently. After removing items from the vehicle, the two support rods 40 are pushed toward the straight rods 32. When the two support rods 40 overlap with the two straight rods 32, the pull rod 71 resiliently snaps into the receiving slot 72, securing the two support rods 40 in place. This eliminates the need to remove the entire vehicle carrier 20 to access items from the vehicle, reducing retrieval time and unnecessary manipulation.

[0045] When you are finished using the bicycle carrier 20, please refer to the Figure 4 and Figure 5 First, the fixing member 82 of the forcing unit 80 is pulled away from the pivotal position of the two connecting rods 81, so that the two connecting rods 81 can rotate freely at the pivotal position. Then, the upper ends of the two frame rods 40 are folded inward, so that the lower ends of the two frame rods 40 can expand relative to each other, thereby causing the two bearing seats 30 to expand relative to each other, so that the two bearing grooves 31 can be separated from the trailer head, and the carrier frame 30 can be unloaded from the vehicle.

[0046] The bicycle carrier provided by the present invention can selectively fix the support and the frame rod through the two fixing units, allowing the user to adjust the position to take out items from the vehicle without disassembling the entire bicycle carrier. Compared with conventional bicycle carriers that cannot be adjusted and need to be disassembled to take out items, the bicycle carrier provided by the present invention can be adjusted by rotating the two frame rods, which can reduce the time and complexity of disassembling and reassembling the bicycle carrier.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
