Description

Technical Field

[0001] The utility model relates to accessories for an electric scooter, in particular to a cargo rack with movable supporting legs. Background Art

[0002] Existing scooters install a luggage rack on the handlebar to solve the problem of carrying items, so as to avoid driving with items in hand, which affects safety. The luggage rack loaded with heavy objects will affect the balance of the scooter when parked. The scooter is unstable when parked with its own single-sided footrest and is prone to tipping over. Later, additional rollers were installed at the bottom of the luggage rack to provide support to help the scooter maintain balance when parked. The rollers roll with the scooter when driving. However, such additional rollers will affect the passability and steering flexibility of the scooter, and it is inconvenient for the scooter to pass when the road is uneven. Utility Model Content

[0003] The utility model aims to solve the technical problem that the existing scooter has rollers installed on the cargo rack, which affects the passability and flexible steering of the scooter. The utility model provides a cargo rack with movable supporting legs. The supporting legs can be movably extended to support the ground when the scooter is parked, and cooperate with the wheels of the scooter to ensure that the scooter can be parked stably without tipping over. The supporting legs can be movably retracted when the scooter is traveling, ensuring that the scooter maintains the existing passability and flexible steering characteristics.

[0004] The technical solution adopted by the utility model to solve the technical problem is: a cargo rack with movable support legs, including side plates connected to the handlebar and a bottom plate for carrying cargo, characterized in that the bottom plate is provided with movable and retractable support legs on both sides of the bottom, and the support legs can be extended to support the ground when the scooter is parked, and retracted when the scooter is driving. The utility model improves the stability of the scooter when parking cargo through the movable and retractable support legs. When the support legs on both sides of the bottom of the bottom plate are extended to support the ground, they cooperate with the wheels of the scooter to form a multi-point positioning, so that the scooter can be parked stably without tipping over; when the scooter is back on the road, the support legs are retracted, which does not affect the normal driving of the scooter, so that the scooter can maintain its original passability and flexible steering characteristics.

[0005] As a further improvement and supplement to the above technical solution, the utility model adopts the following technical measures: the upper end of the support leg is rotatably connected to the bottom of the base plate, and the lower end of the support leg is the ground contact end. The support leg can be rotatably released by kicking the ground contact end in the forward direction of the scooter, and the support leg can be rotatably retracted by kicking the ground contact end in the backward direction of the scooter or by making the scooter move forward; an elastic mechanism with a tension spring is connected between the base plate and the support leg, and the tension spring extends when the support leg is rotated and released, and returns to its original position and shortens when the support leg is rotated and retracted. The support leg is rotatably connected to the bottom of the base plate, and when parking, the lower end of the support leg is kicked forward toward the side of the forward direction of the scooter, and the support leg can be rotatably released, and the lower end of the support leg is kicked backward or the scooter is made to move forward, and the support leg can be rotatably retracted. The elastic mechanism utilizes the axial expansion and contraction deformation of the tension spring to elastically rotate and retract the supporting leg. When the supporting leg needs to be released, the supporting leg is kicked forward with force to overcome the elastic force of the tension spring and elastically rotate and release the supporting leg. During this process, the tension spring stretches and becomes longer; when the supporting leg needs to be retracted, the supporting leg is lightly kicked backward in the opposite direction, or the scooter is pushed forward to utilize the friction between the ground-contacting end and the ground, and with the help of the tension spring reset, the supporting leg can be quickly rotated and retracted. During this process, the tension spring shrinks and shortens. After the supporting leg is retracted into place, the tension spring tightens the supporting leg and elastically damps the supporting leg when the scooter vibrates during driving to prevent the supporting leg from shaking.

[0006] The elastic mechanism includes a tension spring and two hingedly connected first and second brackets. The rotation plane formed by the hinged connection of the first and second brackets is parallel to the rotation plane of the support leg. One end of the tension spring is connected to the first connection part set on the bottom plate, and the other end of the tension spring is connected to the second connection part set on the first bracket. The second bracket is fixed to the upper end of the support leg. The tension spring in the elastic mechanism adjusts the elastic rotation and retraction of the support leg and the elastic shock absorption after being retracted into place through telescopic deformation; the two brackets are hinged and can rotate relative to each other on a plane parallel to the rotation of the support leg. At the same time, one end of the tension spring is connected to the first bracket. During the retraction and extension of the support leg, the first bracket together with one end of the tension spring connected thereto can rotate relative to the second bracket and the support leg, and then the tension spring can also rotate relative to the first connection part connected thereto on a plane parallel to the rotation of the support leg. The rotation of the tension spring plus the telescopic deformation work together to realize the elastic rotation and retraction of the support leg.

[0007] Both ends of the tension spring are provided with hooks, the first connection part and the second connection part are cross bars that can hang the hooks, and the two cross bars are respectively arranged on the bottom plate and the first bracket. The connection between the tension spring and the two connection parts is hooked to the cross bar, the tension spring is provided with hooks at both ends, and the two connection parts are cross bars.

[0008] The first bracket is composed of two parallel and opposite curved curved plates, a pin rod is inserted between the two curved plates facing the front end of the tension spring as a crossbar for hanging the hook, and the second bracket is a single plate hinged between the rear ends of the two curved plates facing away from the tension spring, the single plate is fixed to the upper end of the support leg, the upper end of the support leg passes through the arc gap formed by the extension of the two curved plates, and maintains a gap with the curved plates. The first bracket and the second bracket are both plate members, wherein the first bracket is composed of two curved plates extending in an arc, a pin rod is inserted through the front ends of the two curved plates as a crossbar for hanging the hook at one end of the tension spring, and the second bracket is a single plate hinged between the rear ends of the two curved plates; the upper end of the support leg passes through the arc gap of the two curved plates and cooperates with the gap of the curved plates, and the support leg will not interfere with the first bracket when rotating and retracting.

[0009] The bottom plate and the side plate are fixedly connected, and a stopper bar extending outward is provided at the connection between the two, and the stopper bar can abut against the support leg to limit its position when the support leg is rotated and retracted. The function of the stopper bar is to contact and limit the support leg when the support leg is rotated and retracted, so that the support leg can be rotated to a suitable angle after being retracted, which is convenient for kicking the support leg next time, and can also effectively prevent the support leg from rotating too far and hitting the bottom plate or the side plate.

[0010] The bottom plate is fixedly connected by two side frames and the side plates, the side frames are composed of a vertical part and a horizontal part which are integrated with the upper and lower parts, the vertical parts of the two side frames are respectively fixed to the bent edges extending from the two sides of the side plates by bolts, and the horizontal parts of the two side frames are respectively fixed to the two sides of the bottom of the bottom plate by bolts; the supporting legs of the bottom plate on both sides of the bottom are rotatably connected to the bottom of the bottom plate through the horizontal parts of the corresponding side frames and the intermediate frame arranged between the two horizontal parts, the two ends of the intermediate frame are respectively fixedly connected to the two supporting legs, the upper ends of the supporting legs extend toward the two sides of the bottom plate to form horizontal axis sections which are perpendicular to the long direction of the supporting legs, one end of the horizontal axis section is rotatably connected to the horizontal part of the corresponding side frame, the other end of the horizontal axis section is fixedly connected to the corresponding end of the intermediate frame, and the horizontal part of the side frame is provided with a mounting hole for rotatably connecting the horizontal axis section. The bottom plate and the side plate are detachably fixed by bolts through two side frames, and the vertical and horizontal parts of each side frame are respectively used to fix the side plate and the bottom plate; a common middle frame is also arranged under the bottom plate to drive the supporting legs on both sides to work in conjunction and to be retracted or released together; since the supporting legs are rotatably connected to the horizontal parts of the corresponding side frames and the supporting legs are fixed to the middle frame, as long as one supporting leg is movably retracted or released, the other supporting leg can be driven to move synchronously through the linkage of the middle frame; the supporting legs are rotatably connected to the horizontal parts of the corresponding side frames through the horizontal axis sections extending from the upper ends thereof and are fixed to the common middle frame.

[0011] The intermediate frame includes a connecting rod and transition plates at both ends thereof, one end of the transition plate is sleeved and fixed to the end of the connecting rod, and the other end of the transition plate is sleeved and fixed to one end of the transverse axis section. The intermediate frame is composed of a connecting rod and transition plates at both ends thereof, and the transition plates are fixed to the connecting rod and the transverse axis section at the upper end of the supporting leg by means of sleeved holes. The cross section of the connecting rod can be a polygon such as a rectangle and a square and other shapes that will not rotate relative to each other, so that the supporting legs on both sides can be linked with the help of the intermediate frame and can be retracted or released synchronously.

[0012] The bottom plate and / or the side plate are provided with binding holes for binding ropes. The binding holes are used for threading ropes to bind the articles placed on the position-limiting load carrier. The binding holes can be provided on both the bottom plate and the side plate, or on one of the plates.

[0013] The side panel is opened at the edge adjacent to the bottom panel and extends upward to form a card interface for disassembling and connecting the handlebar stem. The card interface is used for the detachable connection between the side panel and the handlebar stem of the scooter. During installation, a card seat that matches the shape of the card interface is preset on the handlebar stem. The edge of the card seat leaves a card slot that matches the thickness of the side panel where the card interface is located. When the side panel and the card interface are aligned with the card seat and inserted, part of the plate around the card interface is inserted into the card slot, the side panel and the card seat can be docked and installed, and then the cargo rack can be installed on the handlebar stem. After stacking items on the bottom panel, the side panel will tend to sink due to the load. The tighter the clamping between the side panel and the card seat, the more secure the installation of the cargo rack.

[0014] The utility model improves the stability of the scooter when it is parked with objects by means of movably retractable supporting legs. When the supporting legs are extended to support the ground, the scooter is more stable when parked with a load and is not easy to tip over. When the supporting legs are retracted, the normal running of the scooter on the road is not affected, and the scooter can maintain its original passability and flexible steering characteristics.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, a cargo rack with movable supporting legs comprises a side plate 1 connected to a handlebar stem and a bottom plate 2 for carrying cargo, the two plates are fixedly connected, the side plate 1 is opened at an edge adjacent to the bottom plate 2 and extends upward to form a card interface 16 for disassembling and connecting the handlebar stem, the card interface 16 is an isosceles trapezoidal card interface that gradually decreases in diameter from bottom to top, the opening edge of the isosceles trapezoidal card interface is an arc-shaped edge 16-1, and the bottom plate 2 is provided with a movable and retractable supporting leg 3 on both sides of the bottom, the supporting leg 3 can be extended to support the ground when the scooter is parked, and can be retracted when the scooter is driving. Specifically, the upper end of the supporting leg 3 is rotatably connected to the bottom of the base plate 2, and the lower end of the supporting leg 3 is the ground-contacting end. The supporting leg 3 can be rotated to be released by kicking the ground-contacting end in the forward direction of the scooter, and the supporting leg 3 can be rotated to be retracted by kicking the ground-contacting end in the backward direction of the scooter or making the scooter move forward; an elastic mechanism with a tension spring 4 is connected between the base plate 2 and the corresponding supporting leg 3. When the supporting leg 3 is rotated to be released, the tension spring 4 of the elastic mechanism is extended, and when the supporting leg 3 is rotated to be retracted, the tension spring 4 is restored and shortened.

[0025] The utility model utilizes a movably retractable supporting leg to improve the stability of the scooter when it is parked. When parking, the supporting leg is kicked forward to overcome the elastic force of the tension spring and elastically rotate to release the supporting leg. In this process, the tension spring is stretched and lengthened. When both supporting legs are released to support the ground, they cooperate with the wheels of the scooter to form a multi-point positioning, so that the scooter is parked stably with a load and does not tip over. When the scooter needs to go on the road again, the supporting leg is lightly kicked backward in the opposite direction, or the scooter is pushed forward to utilize the friction between the ground-contacting end and the ground, and the supporting leg is quickly rotated and retracted with the help of the tension spring reset. In this process, the tension spring shrinks and shortens. After the supporting leg is retracted, the tension spring tightens the supporting leg and can elastically damp the supporting leg when the scooter vibrates during driving to prevent the supporting leg from shaking. After the supporting leg is retracted, it will not affect the normal driving of the scooter. The scooter still retains the original passability and flexible steering characteristics of the front and rear wheels.

[0026] Furthermore, the elastic mechanism includes a tension spring 4 and two hingedly connected first brackets and second brackets. The rotation plane formed by the hinged connection of the first bracket and the second bracket is parallel to the rotation plane of the support leg 3. Both ends of the tension spring 4 are provided with hooks 4-1. The hook at one end of the tension spring hooks the first connecting portion 7 provided on the bottom plate 2, and the hook at the other end of the tension spring hooks the second connecting portion 8 provided on the first bracket. The second bracket is fixed to the upper end of the support leg 3. The first connecting portion 7 and the second connecting portion 8 are both pins that can be matched with the hook 4-1. The two pins are respectively provided on the bottom plate 2 and the first bracket. Figure 2 and Figure 3 As shown, taking the decomposition of the matching elastic mechanism on a supporting leg as an example, the first bracket is composed of two parallel and opposite arc-shaped bent plates 5, and a pin rod is inserted between the two bent plates 5 towards the front end of the tension spring 4 as a cross bar for hanging the hook 4-1; the second bracket is a single plate 6 hinged between the rear ends of the two bent plates 5 facing away from the tension spring 4, the single plate 6 and the upper end of the supporting leg 3 are fixed, and the upper end of the supporting leg 3 passes through the arc-shaped gap formed by the extension of the two bent plates 5 and maintains a gap with the bent plates 5.

[0027] The tension spring in the elastic mechanism adjusts the elastic rotation and retraction of the support leg and the elastic shock absorption after it is retracted into place through telescopic deformation. Since the two brackets are hinged, they can also rotate relative to each other on a plane parallel to the rotation of the support leg. At the same time, the hook at one end of the tension spring hooks the pin rod set on the first bracket, and the hook at the other end hooks the pin rod set on the bottom plate. During the process of rotation and retraction of the support leg, the two bent plates together with one end of the tension spring connected thereto can rotate relative to the single plate and the support leg fixing the single plate. The tension spring can also rotate relative to the pin rod corresponding to the first connecting part connected thereto on a plane parallel to the rotation of the support leg. The rotation of the tension spring and the telescopic deformation along the axial direction work together to realize the elastic rotation and retraction of the support leg.

[0028] Furthermore, the bottom plate 2 is as Figure 3 and Figure 4 As shown, the side panels 1 are fixedly connected by two side frames 10, the side frames 10 are composed of a vertical portion 10-1 and a horizontal portion 10-2 which are integrally connected to each other. The vertical portions 10-1 of the two side frames 10 are respectively fixed to the bent edges extending from both sides of the side panels 1 by bolts 11, and the horizontal portions 10-2 of the two side frames 10 are respectively fixed to both sides of the bottom of the bottom panel 2 by bolts; the support legs 3 of the bottom panel 2 are connected to the horizontal portions 10-2 of the corresponding side frames 10 and the horizontal portions 10-2 arranged on the two horizontal portions 10- 2 is rotatably connected to the bottom of the bottom plate 2, and the two ends of the middle frame are fixedly connected to the two support legs respectively. The upper ends of the support legs 3 extend to the two sides of the bottom plate 2 to form a transverse axis section 3-1 perpendicular to the long direction of the support legs 3. One end of the transverse axis section 3-1 is rotatably connected to the transverse portion 10-2 of the corresponding side frame 10, and the other end of the transverse axis section 3-1 is fixedly connected to the corresponding end of the middle frame. The transverse portion 10-2 of the side frame 10 is provided with a mounting hole 12 for rotatably connecting the transverse axis section 3-1. Figure 2As shown, the intermediate frame includes a connecting rod 13 and transition plates 14 disposed at both ends thereof. One end of the transition plate 14 has a hole and is sleeved and fixed to the end of the connecting rod 13, and the other end of the transition plate 14 has a hole and is sleeved and fixed to one end of the transverse axis section 3-1.

[0029] The bottom plate and the side plate are detachably connected and fixed by bolts with two side frames on the left and right sides. The vertical part and the horizontal part of each side frame are respectively used to fix the side plate and the bottom plate, thereby fixing the side plate and the bottom plate. An intermediate frame is also arranged below the bottom plate to link the two supporting legs to realize synchronous rotation release or retraction. The upper end of each supporting leg extends to form a transverse axis section and is rotationally connected to the transverse part of the corresponding side frame. At the same time, the transverse axis section is also fixed to the intermediate frame, and the supporting legs on both sides are linked by the intermediate frame. The intermediate frame is composed of a connecting rod and a transition plate fixed at both ends. The connecting rod cross section of this embodiment adopts a quadrilateral shape, and the transition plate is also opened with a hole of a corresponding shape to be sleeved and fixed. There is no relative rotation between the connecting rod and the transition plate, and it is further reinforced by welding. The transition plate and the transverse axis section of the corresponding supporting leg are also only opened with a hole for sleeve, and are reinforced by welding to realize fixed connection. When the supporting leg on one side is rotated to release or retract, it can be linked by the intermediate frame, and the supporting leg on the other side is also rotated to release or retract synchronously.

[0030] like Figure 5 As shown, a lever 9 extending outward is provided at the connection between the bottom plate 2 and the side plate 1. The lever 9 in this embodiment is preferably an extension section of the bottom plate 2 downward. When the support leg 3 is rotated and retracted, the lever 9 can abut against the support leg 3 to limit its maximum rotation range. At the same time, a binding hole 15 for binding ropes is opened on the bottom plate 2 and / or the side plate 1. Both plates can have holes, or any of them can have holes, which are used to pass ropes to bind and fix the items placed on the cargo rack. In this embodiment, holes are preferably opened on both plates, wherein the binding holes on the side plates are also opened on the folded edges formed by the bending of their edges, and the binding holes on the bottom plate are opened at the front edge of the plate.

[0031] like Figure 6 and 7As shown, the luggage rack is detachably connected to the handlebar tube 17 of the scooter through the isosceles trapezoidal bayonet opening on the side panel 1. A holder 18 matching the shape of the bayonet is preset on the handlebar tube 17. A slot 18-1 matching the thickness of the side panel where the card interface is located is reserved at the edge of the holder. When the side panel 1 is inserted into the holder 18 together with the bayonet, so that part of the plate around the bayonet is inserted into the slot 18-1, the side panel 1 and the holder 18 can be docked and installed, and then the luggage rack is installed on the handlebar tube 17. When items are stacked on the bottom plate, the side panel will tend to sink due to the load. The tighter the clamping between the side panel and the holder, the more secure the installation of the luggage rack. The shape of the isosceles trapezoidal bayonet can make the side panel and the holder on the handlebar tube more securely installed, and the side panel clamping load is more balanced, so that the entire luggage rack can be firmly installed on the handlebar tube of the scooter. The arc-shaped edge of the opening can ensure smooth connection, installation or removal of the side panels and the holder, and avoid jamming during the disassembly process due to sharp straight edges and corners. When the carrier is not in use, it can be removed from the handlebar tube, and the side panels can be lifted to gradually disengage the bayonet from the slot. After the two are completely disengaged, the carrier can be removed from the handlebar tube. In addition, the side panels of the carrier can be opened to reduce weight, and the cross section of the side frame and the holder can also use holes to reduce weight. When the scooter is parked during use, put down the two support legs, and put away the two support legs before going on the road.
