[0004] For example, the storage space of the aforementioned electric tricycles is usually only located on both sides of the dashboard, and the effective volume is generally insufficient. This results in insufficient capacity to accommodate the user's personal belongings. Necessities such as rain gear and repair tools often need to be stored externally, which affects driving safety and reduces space utilization. Utility Model Content

[0005] The purpose of this solution is to provide a storage structure for electric tricycles to address the existing problem of increasing storage space in electric tricycles.

[0006] To achieve the above objectives, this solution provides a storage structure for an electric tricycle, including a storage component disposed on the electric tricycle, the storage component comprising: The storage compartment is an open-end structure; the storage compartment is L-shaped and located below the seat of the electric tricycle. The connecting chamber is an open-end structure, with one end connected to the storage chamber. The upper and lower sides of the connecting chamber are provided with buckles, which are used to fix and connect to the seat and frame of the electric tricycle, respectively. A door, which is hinged to the connecting chamber, is used to close the opening at the other end of the connecting chamber.

[0007] The principle and effect of this solution are as follows: By optimizing the use of the unused space under the seat of the electric tricycle, the storage component is designed as an "L"-shaped storage chamber combined with a connecting chamber with openings at both ends. The "L"-shaped storage chamber can adapt to irregular spaces under the seat to maximize storage volume. The connecting chamber is fixed to the seat and frame of the electric tricycle by the upper and lower side fasteners, respectively, so that the storage component is installed stably without damaging the original structure of the vehicle. At the same time, the opening is closed by the door that is hinged to the connecting chamber. In this way, the unused space under the rear seat of the electric tricycle is utilized, which improves storage capacity without affecting the normal use function and driving comfort of the vehicle. It solves the problem of users having to externally store their personal items (such as rain gear, repair tools, etc.).

[0008] Furthermore, the connecting chamber has a rectangular structure, and the storage chamber is located above the connecting chamber, so that the bottom surfaces of the connecting chamber and the storage chamber form an "L" shape.

[0009] The principle and effect of this solution are as follows: through the above settings, the connection chamber is assembled with the seat and frame, and the space of the storage chamber is maximized.

[0010] Furthermore, a protective net is provided at the outlet end of the storage chamber.

[0011] The principle and effect of this solution is that the protective netting blocks the items inside the compartment, preventing small items (such as rain gear accessories, tool parts, etc.) from falling out of the storage compartment.

[0012] Furthermore, the connecting chamber is provided with several heat dissipation holes, which are connected to the interior of the connecting chamber; the door is provided with several through holes, and dustproof mesh is provided on the through holes.

[0013] The principle and effect of this solution are as follows: Since the motor needs to be installed on the lower side of the connecting chamber, heat dissipation holes and through holes are set on the connecting chamber to form an air circulation channel, so as not to affect the heat dissipation of the motor below.

[0014] Furthermore, the buckle plate has several blind holes along its length, and bolts are installed in the blind holes. The seat and the frame are both provided with threaded holes that mate with the bolts.

[0015] The principle and effect of this solution are as follows: through the above settings, the buckle plate is fixedly connected to the seat and frame of the electric tricycle, thereby installing the storage compartment and connecting compartment under the seat and above the motor.

[0016] Furthermore, the buckle plate located on the lower side of the connecting chamber is hinged to the box door, and the area of ​​the box door is not less than the opening area of ​​the connecting chamber.

[0017] The principle and effect of this solution are as follows: the hinge enables the door to flip open and close; the door area can completely cover the opening of the connecting chamber, preventing items from falling out of the storage chamber.

[0018] Furthermore, the buckle plate located on the upper side of the connecting chamber is provided with a lock hole, and the door is provided with a lock head that cooperates with the lock hole. The lock head is used to insert into the lock hole and lock the door and buckle plate together.

[0019] The principle and effect of this solution is that the lock head is inserted into the lock hole to lock the door and the snap plate.

[0020] Furthermore, the connecting chamber has several anti-collision protrusions on the side near the door, and the door has anti-collision blocks that cooperate with the anti-collision protrusions.

[0021] The principle and effect of this solution is to offset the impact when the door closes or when the vehicle is bumpy.

[0022] Furthermore, several hooks are provided on the inner top side of the connecting chamber.

[0023] The principle and effect of this solution is that it can hang and store small items such as rain gear and repair gloves.

[0024] Furthermore, the nameplate of the electric tricycle is located on the outside of the door.

[0025] The principle and effect of this solution are as follows: Since this storage component is installed under the rear seat of the electric tricycle, it will replace the original structure at the back of the tricycle, so the license plate and other items can be installed on the door.

Detailed Implementation

[0028] The following will describe the concept and technical effects of this utility model clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Example 1: Please see Figures 1-3 This embodiment discloses a storage structure for an electric tricycle, aiming to solve the problem of insufficient storage capacity in existing electric tricycles by making full use of the unused space under the seat. The overall structure includes a storage component 1 mounted on the electric tricycle, which consists of a storage chamber 11, a connecting chamber 13, and a door 12. The storage chamber 11 is an "L"-shaped structure open at one end, and the connecting chamber 13 is a rectangular structure open at both ends. Both are integrally injection molded from high-strength polyethylene. The connecting chamber 13 has external dimensions of 32-36cm in length, 19-23cm in width, and 13-16cm in height. The horizontal section of the storage chamber 11 is fixed to the top surface of the connecting chamber 13 by hot-melt welding, so that their bottom surfaces together form an "L"-shaped structure. The top surface of the connecting chamber 13 forms an "L"-shaped horizontal section (28-32cm in length), and the bottom surface of the vertical section (16-19cm in height) of the storage chamber 11 forms an "L"-shaped vertical section. The connection between the horizontal and vertical sections uses a rounded transition with a radius of 3-5cm, which not only adapts to the irregular unused space under the seat in both horizontal and vertical directions, but also maximizes the filling of the unused three-dimensional space in this area, increasing the storage capacity by 40%-50% compared to the traditional structure.

[0029] The inner wall of the storage chamber 11 has 3-4 reinforcing ribs (not shown) evenly distributed along the height direction. The reinforcing ribs are 2-3mm thick and spaced 6-8cm apart. This can improve the load-bearing capacity of the storage chamber 11 and ensure that it does not deform when heavy objects such as a 3-5kg maintenance tool kit are placed on it. A protective net 16 is fixed to its open end (the end facing the connecting chamber 13). The protective net 16 is made of high-strength polyethylene and is fixed to the edge of the open end of the storage chamber 11 by 4 plastic pins. This can block rain gear accessories, small maintenance parts and other easily scattered items in the storage chamber 11 and prevent items from falling into the connecting chamber 13 when the vehicle is bumpy or the door 12 is opened.

[0030] Fastener plates 14 are fixed to the upper and lower sides of the connecting chamber 13, respectively. The fastener plates 14 are made of cold-rolled steel plates with a thickness of 2.5-3mm and are fixed to the outer wall of the connecting chamber 13. The fastener plates 14 have 4-6 blind holes 141 along their length, and hexagon socket bolts 142 are installed in the blind holes 141. The bottom of the seat of the electric tricycle (corresponding to the upper fastener plate 14) and the crossbeam of the frame (corresponding to the lower fastener plate 14) are both pre-drilled with threaded holes that mate with the bolts 142. Through the threaded connection of the bolts 142 with the threaded holes, the connecting chamber 13 can be firmly fixed between the seat and the frame, preventing the storage component 1 from shaking or shifting during vehicle operation, and without damaging the original structure of the vehicle. In addition, the side wall of the connecting chamber 13 (the side facing the electric tricycle motor) is provided with 7 strip-shaped heat dissipation holes 131, which are arranged in a matrix. The spacing between adjacent heat dissipation holes 131 is 4-6cm. The heat dissipation holes 131 penetrate the side wall of the connecting chamber 13 to achieve communication between the inside and the outside. Near the opening edge of the door 12, a nitrile rubber anti-collision protrusion 132 is glued to each of the four corners of the connecting chamber 13. 2-3 plastic hooks 15 are welded to the inner top of the connecting chamber 13, which can be used to hang small items such as rain gear and repair gloves, so as to realize the classification and storage of items and avoid stacking with large items, which would cause inconvenience in access.

[0031] The door 12 is hinged to the lower panel 14 of the connecting chamber 13 by two 304 stainless steel hinges. The hinges are fixed to both ends of the lower edge of the door 12 by countersunk screws. The hinge rotation angle range is 0-100°, allowing the door 12 to be flipped down and opened, making it convenient for users to retrieve items from the side or rear of the vehicle. The external dimensions of the door 12 are 2-3mm larger than the opening size of the connecting chamber 13 (e.g., if the opening of the connecting chamber 13 is 32cm long and 19cm wide, then the door 12 is 34cm long and 21cm wide). This ensures that the door 12 can completely cover the opening of the connecting chamber 13 when closed, preventing items in the storage chamber 11 from falling through the gaps and reducing the intrusion of external dust. The door 12 has a through hole that matches the heat dissipation hole 131. An 80-100 mesh nylon dustproof mesh 121 is installed inside the through hole. The dustproof mesh 121 can prevent dust and sand particles in the air from entering the connecting chamber 13 and the storage chamber 11. At the same time, the heat dissipation hole 131 and the through hole form a "bottom in, top out" air circulation channel, which can guide the heat generated by the motor to diffuse upward and be discharged. On the side of the door 12 facing the connecting chamber 13, an EVA foam anti-collision block 123 (1-2mm larger than the anti-collision protrusion 132) is attached to the position of the anti-collision protrusion 132. When the door 12 is closed, the anti-collision protrusion 132 is embedded in the anti-collision block 123, which can offset the rigid collision between the door 12 and the connecting chamber 13, reduce the abnormal noise caused by component vibration during driving, and avoid structural wear caused by long-term collision. In addition, a pin tumbler lock cylinder 122 (with a copper alloy cylinder and a 5-6mm protruding bolt) is installed on the side of the door 12 facing the connecting chamber 13. A circular lock hole 143 (9-11mm in diameter) is provided in the middle of the upper snap plate 14 of the connecting chamber 13 to cooperate with the lock cylinder 122. When the door 12 is closed, the bolt of the lock cylinder 122 is pushed into the lock hole 143 to lock the door 12 to the upper snap plate 14. A nameplate 17 is fixed to the outside of the door 12. In this embodiment, an electric vehicle license plate is used. The license plate is fixed to the middle of the upper half of the outside of the door 12 by stainless steel rivets. Since this storage component 1 will replace part of the original rear structure of the vehicle after being installed under the rear seat of the electric tricycle, the license plate is located on the outside of the door 12.

[0032] When in use, the user opens the lock 122 with the key, flips the door 12 downwards, and puts large items such as repair toolboxes and rain gear storage bags into the storage compartment 11, and hangs small items such as folding umbrellas and repair gloves on the hooks 15. After the items are placed, flip the door 12 upwards to completely cover the opening of the connecting compartment 13, and push the lock 122 to insert the bolt into the lock hole 143 to lock it.

[0033] Example 2: The difference between this embodiment and the previous embodiment is that, in the aforementioned solution, because the storage compartment 11 needs to protect small parts such as umbrellas, when the electric tricycle is traveling, it will vibrate when encountering speed bumps or potholes. Although protective nets and other measures are in place, items in the storage compartment 11 are still easily shaken out of the storage compartment 11 and fall into the connecting compartment 13. When the door 12 is opened again, the items are likely to fall to the ground. More importantly, since the items are not restrained in the storage compartment 11, they will also vibrate when the vehicle shakes, impacting the storage compartment 11 and producing abnormal noise. This embodiment further optimizes the interior of the storage compartment 11 to solve the above problems.

[0034] Please see Figure 5 It also includes a limiting component 2, which includes an airbag 21 and an air gun 22. The airbag 21 is located inside the storage chamber 11 and is a strip-shaped airbag that fits along the inner wall of the storage chamber 11. The air gun 22 is located on the connecting chamber 13. In this embodiment, the air gun 22 used is a manual reciprocating air gun 22 (similar to an air gun for inflating a basketball). The airbag 21 and the air gun 22 are connected by a pipe, and the pipe is equipped with a one-way valve (not shown) so that the air enters the airbag 21 in one direction through the reciprocating extension and retraction of the piston rod of the air gun 22, causing the airbag 21 to expand and fill the entire storage chamber 11. The airbag 21 is connected to a pressure relief valve 23. When the airbag 21 expands to its limit, the pressure relief valve 23 opens to release the pressure from the airbag 21. At the same time, after the airbag 21 comes into contact with the items in the storage chamber 11, if the pressure on the airbag 21 exceeds the limit, the pressure relief valve 23 will also open to release air from the airbag 21, preventing it from expanding beyond the limit and rupturing.

[0035] Furthermore, to improve the inflation and deflation of the airbag 21, the limiting assembly 2 also includes a fixed pulley 24, a cable 25, and a spring 26. The fixed pulley 24 is mounted on the connecting chamber 13. The cable 25 is fixedly connected to the free end of the piston rod 221 of the air gun 22, and the cable 25 passes around the fixed pulley 24, changing its direction of movement. The free end of the cable 25 is connected to the door 12 by a fixing bolt. It should be noted that, to better facilitate opening and closing the door 12, thereby extending or retracting the air gun 22, a pulley assembly can be added along the movement trajectory of the cable 25, making the opening and closing of the door 12 smoother. One end of the spring 26 is fixedly connected to the piston (not shown) of the air gun 22, and the free end is fixedly connected to the inner wall of the cylinder of the air gun 22. Thus, when the box door 12 is closed, the pre-tightening force drives the piston and piston rod 221 of the air gun 22 to return to the initial limit position, thereby compressing the space in the enclosed cavity between the piston and the cylinder, squeezing the gas into the airbag 21 to make it expand, thereby covering and restricting the movement of small parts such as umbrellas.

[0036] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
