[0002] Motorcycles are a popular mode of transportation due to their small size and ease of parking. To improve their loading convenience, people often install a rear box on the motorcycle's tail rack, which requires a connector to support the rear box.

[0003] In existing motorcycles, the support structure of the rear cargo box is prone to bending when subjected to external impact, causing the cargo box to become tilted or fall off, rendering it unusable. Utility Model Content

[0004] This utility model proposes a motorcycle frame external trunk connector to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a motorcycle frame external trunk connector, comprising two mounting parts, which are detachably mounted on the rear side of the motorcycle frame by means of bolts, and a support plate is fixedly connected to one end of the two mounting parts, wherein the support plate can support the motorcycle trunk, and the cross-section of the support plate is rectangular.

[0006] The effect achieved by the above components is as follows: when it is necessary to install the motorcycle trunk, the staff first installs the two mounting pieces on both sides of the motorcycle frame with bolts, and the support plate at one end of the mounting piece provides support for the motorcycle trunk.

[0007] Preferably, the bottom of the support plate is provided with an inclined plate, wherein the inclined plate is made of aluminum alloy, and both ends of the inclined plate are fixedly connected to mounting plates. The two mounting plates are detachably connected to the support plate and the back of the motorcycle frame by means of bolts.

[0008] The effect achieved by the above components is as follows: When using the support plate to support the motorcycle's rear cargo box, the operator moves the ramp, and the mounting plates at both ends of the ramp abut against the bottom of the support plate and the rear side of the motorcycle frame, respectively. Finally, the ramp is fixed with bolts. The ramp, the motorcycle frame, and the support plate form a stable triangular structure, thereby improving the stability of the support plate. By setting the ramp, the effect of supporting the support plate is achieved. At the same time, the aluminum alloy material of the ramp increases its own hardness, preventing the ramp from bending when the support plate is under stress.

[0009] Preferably, a protective pad is fixedly connected to the side of the support plate near the motorcycle frame, wherein the cross-section of the protective pad is arc-shaped.

[0010] The effect achieved by the above-mentioned components is to support the driver's back by setting up an arc-shaped protective pad, thereby achieving the effect of protecting the driver's back.

[0011] Preferably, two symmetrical horizontal plates are fixedly connected at the center of the support plate, wherein the surface of the horizontal plates is provided with mounting holes, and the mounting holes are used to install the trunk with bolts.

[0012] The aforementioned components achieve the following effect: when the trunk needs to be installed, the worker can pass screws through the mounting holes in the trunk and the cross panel, and finally use nuts to fix the screws, thus achieving the effect of fixing the trunk and bringing convenience to the worker in installing the trunk.

[0013] Preferably, the support plate is provided with limiting mechanisms on both sides, the limiting mechanisms including two L-shaped plates, each side of the support plate having mounting holes, the two L-shaped plates being slidably inserted into the sides of the support plate via the mounting holes, two grooves being formed on both sides of the support plate, the support plate having insert rods via the grooves, and the L-shaped plates having a plurality of insertion holes evenly formed at the corresponding insertion rods, wherein the size of the insertion rods is adapted to the size of the insertion holes, and the two ends of the springs are fixedly connected to the inner wall of the grooves and the insertion rods, respectively.

[0014] The aforementioned components achieve the following effect: After the trunk is installed, the worker pulls the insert rod, which moves within the groove, causing the spring to deform. The worker then moves the L-shaped plate, inserting its horizontal end into the mounting hole. Finally, the vertical end of the L-shaped plate rests against the trunk surface. The worker releases the insert rod, and under the spring's restoring force, the insert rod inserts into the L-shaped plate's hole, thus fixing the L-shaped plate in place. The two L-shaped plates, set by the limiting mechanism, effectively limit the trunk's movement, preventing it from swaying left and right.

[0015] Preferably, a pull plate is fixedly connected to one side of the insertion rod, wherein the surface of the pull plate is provided with anti-slip texture.

[0016] The effect achieved by the above-mentioned components is to increase the contact area between the worker's hand and the insertion rod by setting up the pull plate, which makes it more convenient for the worker to move the insertion rod.

[0017] Preferably, both sides of the insertion rod are fixedly connected to sliders, wherein the groove is provided with a sliding groove corresponding to the slider, and the slider and the sliding groove are slidably adapted to each other.

[0018] The effect achieved by the above components is that by moving the slider of the insertion rod in the groove of the groove, the movement direction of the insertion rod is restricted, thus preventing the insertion rod from shaking.

[0019] Preferably, one end of the insertion rod is fixedly connected to a pointed protrusion, wherein the tip of the pointed protrusion is far away from the insertion rod.

[0020] The effect achieved by the above-mentioned components is that the pointed protrusions guide the insertion rod, making it easier for workers to insert the insertion rod into the socket of the L-shaped plate.

[0021] When using a support plate to support the motorcycle's rear cargo box, the worker moves the ramp, with the mounting plates at both ends of the ramp abutting against the bottom of the support plate and the rear of the motorcycle frame, respectively. Finally, the ramp is fixed with bolts. The ramp, the motorcycle frame, and the support plate form a stable triangular structure, thereby improving the stability of the support plate. By setting up the ramp, the support plate is effectively supported. At the same time, the aluminum alloy material of the ramp increases its own rigidity, preventing the ramp from bending when the support plate is under stress. Attached Figure Description

[0030] The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] In this embodiment:

[0032] Reference Figure 1-5 As shown, this embodiment discloses an external rear cargo box connector for a motorcycle frame, including two mounting parts 1, which are detachably mounted on the rear side of the motorcycle frame using bolts; and a support plate 2, which is fixedly connected to one end of the two mounting parts 1. The support plate 2 supports the motorcycle cargo box, and its cross-section is rectangular. When installing the motorcycle cargo box, the operator first installs the two mounting parts 1 on both sides of the motorcycle frame using bolts, and the support plate 2 at one end of the mounting parts 1 provides support for the motorcycle cargo box.

[0033] Reference Figure 1-5 As shown, a ramp 3 is provided at the bottom of the support plate 2. The ramp 3 is made of aluminum alloy, and mounting plates 4 are fixedly connected to both ends of the ramp 3. The two mounting plates 4 are detachably connected to the support plate 2 and the rear of the motorcycle frame by bolts. When using the support plate 2 to support the motorcycle's rear cargo box, the operator moves the ramp 3. The mounting plates 4 at both ends of the ramp 3 abut against the bottom of the support plate 2 and the rear of the motorcycle frame, respectively. Finally, the ramp 3 is fixed with bolts. The ramp 3, the motorcycle frame, and the support plate 2 form a stable triangular structure, thereby improving the stability of the support plate 2. By setting up the ramp 3, the support plate 2 is supported. At the same time, the aluminum alloy material of the ramp 3 increases its own rigidity, preventing the ramp 3 from bending when the support plate 2 is under stress.

[0034] Reference Figure 1-5As shown, a protective pad 5 is fixedly connected to the side of the support plate 2 near the motorcycle frame, and the protective pad 5 has an arc-shaped cross-section. The arc-shaped protective pad 5 provides support for the driver's back, achieving the effect of protecting the driver's back. Two symmetrical horizontal plates 6 are fixedly connected to the center of the support plate 2, and the surface of the horizontal plates 6 has mounting holes. When the trunk needs to be installed, the operator passes screws through the mounting holes 71 of the trunk and the horizontal plates 6, and finally secures the screws with nuts, achieving the effect of fixing the trunk and providing convenience for the operator during installation.

[0035] Reference Figure 1-5 As shown, the support plate 2 is provided with limiting mechanisms 7 on both sides. The limiting mechanisms 7 include two L-shaped plates 72, and mounting holes 71 are provided on both sides of the support plate 2. The two L-shaped plates 72 are slidably installed on both sides of the support plate 2 through the mounting holes 71; grooves 73 are provided on both sides of the support plate 2. The support plate 2 is provided with insert rods 75 through the grooves 73. Several insertion holes 76 are evenly provided on the L-shaped plates 72 corresponding to the insertion rods 75. The size of the insertion rods 75 is adapted to the size of the insertion holes 76; springs 74 are fixedly connected at both ends to the inner wall of the grooves 73 and the insertion rods 75 respectively. After the trunk is installed, the worker pulls the insert rod 75, which moves in the groove 73. The spring 74 deforms, and then the worker moves the L-shaped plate 72. The horizontal end of the L-shaped plate 72 is inserted into the mounting hole 71, and finally the vertical end of the L-shaped plate 72 rests against the surface of the trunk. The worker releases the insert rod 75, and under the restoring force of the spring 74, the insert rod 75 is inserted into the insertion hole 76 of the L-shaped plate 72, thus fixing the L-shaped plate 72. The two L-shaped plates 72 set by the limiting mechanism 7 achieve the effect of limiting the trunk and preventing the trunk from shaking from side to side.

[0036] Reference Figure 1-5 As shown, a pull plate 77 is fixedly connected to one side of the insertion rod 75, and the surface of the pull plate 77 is provided with anti-slip texture. The pull plate 77 increases the contact area between the worker's hand and the insertion rod 75, making it easier for the worker to move the insertion rod 75. Slider blocks 79 are fixedly connected to both sides of the insertion rod 75, and grooves 710 are formed in the grooves 73 corresponding to the sliders 79, allowing the sliders 79 to slide smoothly into the grooves 710. The movement of the sliders 79 of the insertion rod 75 within the grooves 73 and the corresponding grooves 710 effectively restricts the direction of movement of the insertion rod 75, preventing it from wobbling. A pointed protrusion 78 is fixedly connected to one end of the insertion rod 75, with the tip of the protrusion 78 away from the insertion rod 75. The pointed protrusion 78 guides the insertion rod 75, making it easier for the worker to insert the insertion rod 75 into the insertion hole 76 of the L-shaped plate 72.

[0037] Working principle: When installing a motorcycle trunk, the worker first uses bolts to install two mounting parts 1 on both sides of the motorcycle frame. The worker then moves the ramp 3, and the mounting plates 4 at both ends of the ramp 3 abut against the bottom of the support plate 2 and the rear of the motorcycle frame, respectively. Finally, the ramp 3 is fixed with bolts. The ramp 3, the motorcycle frame, and the support plate 2 form a stable triangular structure, thereby improving the stability of the support plate 2. The worker then places the motorcycle trunk on the support plate 2 and inserts screws through the mounting holes 71 of the trunk and the horizontal plate 6. Finally, the screws are fixed with nuts, achieving the effect of fixing the trunk. By setting the ramp 3, the support plate 2 is supported. At the same time, the aluminum alloy ramp 3 increases its own rigidity, preventing the ramp 3 from bending when the support plate 2 is under stress.

[0038] After the trunk is installed, the worker pulls the insert rod 75 using the pull plate 77. The insert rod 75 moves in the groove 73, and the slider 79 of the insert rod 75 moves in the slide groove 710 of the groove 73, thus limiting the movement direction of the insert rod 75. The spring 74 deforms. Then, the worker moves the L-shaped plate 72, and the horizontal end of the L-shaped plate 72 is inserted into the mounting hole 71. Finally, the vertical end of the L-shaped plate 72 rests against the surface of the trunk. The worker releases the pull plate 77, and under the restoring force of the spring 74, the insert rod 75 is inserted into the insertion hole 76 of the L-shaped plate 72 with the help of the pointed protrusion 78, thus fixing the L-shaped plate 72. The two L-shaped plates 72 set by the limiting mechanism 7 achieve the effect of limiting the trunk and preventing the trunk from shaking from side to side.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
