Description

Technical Field

[0001] The utility model relates to the technical field of vehicle loading accessories, in particular to an external connection loading tool for vehicles. Background Art

[0002] In modern travel and leisure activities, large sports equipment such as bicycles and snowboards has become an indispensable companion. For the transportation of these equipment, they are generally fixed on a loading tool - a bicycle rack. Specifically, the traditional method is to design and install the bicycle bracket on the top of the vehicle, in the trunk, or fixed by using a suspension device, aiming to effectively utilize the external space of the vehicle and facilitate long-distance travel or daily carrying.

[0003] Among them, although these designs solve the carrying problem to a certain extent, due to the long-term exposure of the loading tool to the outside, plus the bumps and vibrations during vehicle driving, etc., the connection between the loading tool and the vehicle is worn due to vibration and the erosion of external environmental factors (such as rain and sand). And the wear not only affects the stability and safety of the loading tool, but also may shorten its service life and increase the maintenance cost of users. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an external connection loading tool for vehicles to improve the problem of poor stability when carrying items due to wear at the connection between the loading tool and the vehicle.

[0005] The technical solution of the utility model is as follows:

[0006] An external connection loading tool for vehicles includes:

[0007] A connection component, a support component, and an eccentric component disposed between the two. The connection component is rotatably connected to and abuts against the support component. The eccentric component includes an eccentric member and an eccentric driving member. Both ends of the eccentric member are rotatably connected to the support component, and the middle part of the eccentric member abuts against the connection component;

[0008] The eccentric driving member is respectively connected to the support component and the eccentric member, and the eccentric driving member is used to drive the eccentric member to rotate self to eliminate the wear gap at the abutting position between the eccentric member and the connection component.

[0009] In a possible implementation manner, the eccentric member includes an eccentric shaft. At least two outer shafts are provided on the eccentric shaft, and an inner shaft is provided between two adjacent outer shafts. The axis of the inner shaft is eccentrically arranged with the axis of the outer shaft. The outer shaft is used to be rotatably connected to the support component, and the inner shaft is used to abut against the connection component.

[0010] In a possible implementation, the support assembly includes at least two side plates arranged in parallel with each other. Clearance-eliminating rotation holes are formed in the side plates, the eccentric shaft vertically passes through the clearance-eliminating rotation holes, and the outer shaft is rotatably arranged in the clearance-eliminating rotation holes.

[0011] In a possible implementation, the connection assembly includes at least one abutting plate. The abutting plate is arranged between the two side plates, and an abutting notch is formed in the abutting plate;

[0012] A rotating arc surface is arranged around the circumference of the inner shaft. When the eccentric shaft is rotated to make the rotating arc surface face the abutting notch, the contact between the support assembly and the inner shaft is eliminated, and the support assembly and the connection assembly can be rotatably connected to adjust the placement angle.

[0013] In a possible implementation, the support assembly further includes a support bottom plate arranged between the two side plates. Support convex arms are arranged at both ends of the support bottom plate;

[0014] Support holes are formed in the side plates. The support convex arms are snap-fitted into the support holes, and the support bottom plate abuts against the lower end surface of the abutting plate. The support bottom plate is used to support the self-weight of the support assembly.

[0015] In a possible implementation, a clearance-eliminating abutting surface is further arranged around the circumference of the inner shaft. The clearance-eliminating abutting surface is used to abut against the abutting notch.

[0016] In a possible implementation, the eccentric driving member includes a driving torsion spring. The driving torsion spring is arranged outside the side plate and sleeved on one end of the outer shaft. The driving torsion spring is used to drive the eccentric shaft to rotate self in a first direction, so as to eliminate the wear clearance of the inner shaft rotation.

[0017] In a possible implementation, an abutting starting point and an abutting ending point are arranged on the clearance-eliminating abutting surface. When the abutting starting point abuts against the abutting notch, the clearance-eliminating distance is 0 mm. When the eccentric shaft rotates self to make the abutting ending point abut against the abutting notch, the clearance-eliminating distance is 3 mm.

[0018] In a possible implementation, a first clamping hook is arranged at one end of the driving torsion spring, and a second clamping hook is arranged at the other end. The first clamping hook is fixedly connected with the side plate, and the second clamping hook is fixedly connected with the outer shaft.

[0019] In a possible implementation, the eccentric driving member further includes a manual rocker. The manual rocker is connected with the other end of the eccentric shaft. The manual rocker is used to rock the eccentric shaft to rotate self in a second direction.

[0020] The utility model according to the above scheme has the beneficial effect that an external connection load-carrying tool for vehicles includes a connection component connected to the vehicle, a support component for placing equipment, and an eccentric component disposed in the middle of the two. Among them, an eccentric driving member drives an eccentric member to rotate self, thereby eliminating the wear gap at the contact between the eccentric member and the connection component, reducing the risk of gaps at the connection of the load-carrying tool's own structure due to wear between structures, and enabling the utility model to improve the stability of the load-carrying tool's own structure through the structural settings of the eccentric member and the eccentric driving member, and improving the safety when the vehicle transports large equipment.

Detailed Embodiments

[0028] The following further describes the utility model in conjunction with the drawings and embodiments:

[0029] It should be noted that when individuals are faced with the transportation of large sports equipment such as bicycles and skis, they usually need to use a carrying tool installed on the outside of the vehicle, such as installing a bicycle rack on the top of the vehicle, and then fixing the bicycle on the bicycle rack. However, since the existing bicycle racks are exposed to the outside for a long time, coupled with factors such as bumps in vehicle driving, the structure on the bicycle rack is prone to wear, which reduces the structural stability of the bicycle rack itself and also reduces the safety of transporting bicycles on the vehicle. For this reason, the utility model proposes an externally connected carrying tool for vehicles, thereby improving the above-mentioned defects by changing the structure of the bicycle rack itself.

[0030] See Figures 1-5 As shown, the utility model proposes an external connection carrying tool for a vehicle, specifically, the external connection carrying tool includes a connecting assembly, a support assembly and an eccentric assembly arranged therebetween, wherein one end of the connecting assembly is provided with a connecting structure and is fixedly connected to the tow bar at the trunk of the vehicle, and the other end of the connecting assembly is rotatably connected and abutted with the support assembly. In this embodiment, a fixed base for fixing a bicycle is provided on the support assembly, so that the support assembly and the bicycle are supported and hung at the rear of the vehicle through the connecting assembly, thereby realizing the transportation of large sports equipment such as bicycles and skis. In addition, the eccentric assembly includes an eccentric piece and an eccentric driving piece. More specifically, both ends of the eccentric piece are rotatably connected to the other end of the support assembly, and the eccentric piece The middle part is arranged to abut against the connecting component. It needs to be explained that the connecting component lifts the supporting component upward by abutting against the lower end surface of the supporting component, and the eccentric member limits the upward movement of the connecting component through the abutment between the middle part and the connecting component. Among them, the eccentric driving member is arranged at one end of the eccentric member, and the eccentric driving member is connected and fixed to the supporting component, and is also connected and fixed to the eccentric member. The eccentric driving member is used to drive the eccentric member to rotate, thereby eliminating the wear gap at the abutment between the eccentric member and the connecting component, and thereby reducing the risk of gaps at the connection of the carrier's own structure due to wear between the structures. The utility model improves the structural stability of the carrier itself through the structural setting of the eccentric member and the eccentric driving member, and improves the safety of the vehicle when transporting large equipment.

[0031] It should be understood that the wear gaps at the abutment points between the connecting assembly and the supporting assembly, as well as at the abutment points between the eccentric assembly and the connecting assembly, can be eliminated simultaneously through the self-rotation of the eccentric piece. However, due to the action of gravity, the connecting assembly and the supporting assembly are always in abutment with each other. Therefore, it is only necessary to eliminate the gap at the abutment point between the upper eccentric piece and the connecting assembly to improve the stability of the connecting structure.

[0032] In some embodiments, see Figures 1-3, the eccentric member includes an eccentric shaft, on which there are at least two outer shafts and an inner shaft disposed between two adjacent outer shafts. In this embodiment, there are three outer shafts and two inner shafts on the eccentric shaft. Among them, the axis of the inner shaft is eccentrically arranged with the axis of the outer shaft, and the diameter of the inner shaft is 13 mm, and the diameter of the outer shaft is 16 mm. Specifically, the two outer shafts on the outside are rotatably connected to the support assembly, and the inner shaft is in contact with the connection assembly, so as to be in contact with the lower part of the connection assembly through the inner shaft. In addition, the eccentric drive member is fixedly connected to the outer shaft, so as to drive the eccentric member to rotate by itself through the eccentric drive member, change the placement position of the inner shaft, and combine the structure that the outer position of the inner shaft and the outer shaft is eccentrically arranged, so that the inner shaft can generate an upward extrusion force on the lower part of the connection assembly, and eliminate the wear gap between the connection assembly and the support assembly.

[0033] Further, referring to Figures 1-3 , the support assembly includes at least two side plates arranged in parallel to each other. There are clearance-eliminating rotation holes on the side plates. The eccentric shaft is perpendicular to the side plates and passes through the clearance-eliminating rotation holes. In this embodiment, the support assembly includes two side plates. The two outer shafts on the outside are respectively located at the clearance-eliminating rotation holes of the two side plates and are rotatably arranged therewith, so as to drive the eccentric shaft and the side plates to be rotatably connected through the eccentric drive member.

[0034] In this embodiment, referring to Figures 1-3 , the connection assembly includes at least one abutting plate, the abutting plate is arranged between the two side plates, and there is an abutting notch on the side surface of the end of the abutting plate close to the support assembly, and a rotating arc surface is arranged around the circumference of the inner shaft. When the rotating arc surface of the rotating eccentric shaft and the inner shaft is opposite to the abutting notch, the contact between the support assembly and the inner shaft is eliminated, so that the support assembly and the connection assembly can be rotatably connected to adjust the relative placement angle of the two, and further change the relative angle between the support assembly and the connection assembly, and finally enable the carrying tool to be received and the occupied space to be reduced when no items are transported.

[0035] In this embodiment, referring to Figure 3 , the support assembly includes a support bottom plate arranged between the two side plates, and support convex arms are arranged at both ends of the support bottom plate. Among them, support holes are provided on both side plates, and the support convex arms are clamped and installed in the support holes, and the upper end surface of the support bottom plate is in contact with the lower end surface of the abutting plate, so as to support the gravity of the support assembly and the equipment below through the support bottom plate.

[0036] In this embodiment, referring to Figures 3-4 , a clearance-eliminating abutting surface is also arranged on the circumference of the inner shaft. The clearance-eliminating abutting surface is located on the other side of the rotating arc surface. The clearance-eliminating abutting surface is used to abut against the abutting notch, so as to generate an upward extrusion force on the lower part of the abutting plate, and eliminate the wear gap between the connection assembly and the support assembly.

[0037] In this embodiment, refer to Figures 1-3 , the eccentric drive member includes a drive torsion spring. The drive torsion spring is disposed on the outer side surface of the side plate, and the drive torsion spring is sleeved on the outer shaft at one end of the eccentric shaft. Wherein, the drive torsion spring is used to drive the outer shaft of the eccentric shaft and the side plate to rotate, thereby driving the inner shaft to rotate around the first direction, and further eliminating the wear gap existing between the inner shaft and the side plate, and improving the overall structural stability of the load-carrying tool.

[0038] Further, refer to Figures 3-4 , a first clamping hook is provided at one end of the drive torsion spring, and a second clamping hook is provided at the other end. In this embodiment, a hook hole for installing the first clamping hook is clamped on the side plate, so that one end of the drive torsion spring is fixedly connected and clamped with the side plate through the first clamping hook and the hook hole. In addition, the eccentric drive member further includes a spacer plate and a fixing plate both sleeved on the outer shaft of the eccentric shaft, and a torsion spring fixing bolt passing through the outer shaft of the eccentric shaft. Specifically, the spacer plate is located at one end of the drive torsion spring and is between the drive torsion spring and the side plate. The spacer plate can reduce the wear caused by the abutment between the drive torsion spring and the side plate. The torsion spring fixing bolt is located at the other end of the drive torsion spring, and the fixing plate is located between the torsion spring fixing bolt and the drive torsion spring. Wherein, the fixing plate can limit the drive torsion spring to prevent it from deforming along the axial direction of the eccentric shaft under force. In addition, by passing the torsion spring fixing bolt through the outer shaft, the second clamping hook can be clamped with the torsion spring fixing bolt, so that the other end of the drive torsion spring is fixedly connected and clamped with the eccentric shaft through the torsion spring fixing bolt, thereby driving the outer shaft of the eccentric shaft to rotate self-rotationally, and further driving the inner shaft to rotate self-rotationally to eliminate the wear gap.

[0039] Further, refer to Figure 4 , the wear clearance abutting surface is provided with an abutting starting point and an abutting ending point. When the abutting starting point abuts against the abutting notch, the wear clearance distance is 0 mm. When the drive torsion spring drives the eccentric shaft and the inner shaft to rotate self-rotationally so that the abutting ending point abuts against the abutting notch, the wear clearance distance is 3 mm. Specifically, when the structures of both the abutting part between the connecting component and the supporting component and the abutting part between the eccentric part and the connecting component are worn, the abutting starting point of the wear clearance abutting surface abuts against the abutting notch of the abutting plate. When the structures of the two abutting parts are worn to generate a gap, under the action of gravity, the supporting component and the device drive the supporting bottom plate to move downward around the rotating structure, and the supporting bottom plate continues to abut against the lower end surface of the abutting plate. At this time, a wear gap is generated between the abutting plate and the inner shaft, and the abutting state between the inner shaft of the eccentric shaft and the abutting plate is eliminated. The drive torsion spring can drive the outer shaft of the eccentric shaft to rotate around the first direction. Combining with the structural setting of the eccentricity and dislocation between the inner shaft and the outer shaft, the inner shaft is driven to rotate and continue to abut against the abutting plate, thereby eliminating the wear gap existing between the two.

[0040] In some embodiments, refer to Figures 1-3 、 Figure 5The eccentric driving member includes a manual rocker, which is arranged through an outer shaft at the other end of the eccentric shaft. The manual rocker is used to shake the eccentric shaft to rotate around the second direction, so that the rotating arc surface corresponds to the abutment notch of the abutment plate, thereby eliminating the abutment between the support assembly and the inner shaft, thereby facilitating the change of the relative angle between the support assembly and the connecting assembly, and finally retracting and extending the support assembly of the carrier tool to reduce the occupied space.

[0041] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.

[0042] The above is an exemplary description of the present utility model patent in conjunction with the accompanying drawings. It is obvious that the implementation of the present utility model patent is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present utility model patent, or the concept and technical solution of the present utility model patent are directly applied to other occasions without improvement, they are all within the scope of protection of the present utility model.
