Description

[Technical Field]

[0001] The present invention relates to the technical field of electric tricycles, and more particularly to an electric tricycle with a new carrier and battery box structure. [Background technology]

[0002] Electric tricycles are equipped with three wheels, which improve the stability of the cart. Electric tricycles are mainly used to transport cargo over short distances, replacing traditional hand-pushed tricycles, which can greatly improve work efficiency and reduce the workload of workers.

[0003] In the prior art, a utility model with Chinese registration publication number CN210258500U discloses an electric flat platform truck, in which position-regulating railings are fixed to both sides of the vehicle frame, and the position-regulating railings are formed by bending hollow circular tubes into an N shape, and the bottoms of the position-regulating railings are fixed to both sides of the vehicle frame with fixing bolts.

[0004] In the electric flatbed trucks of the prior art cited above, the bottom of the position control railing is fixed, and therefore the space formed by the surrounding position control railings is fixed. Therefore, when loading cargo whose length is longer than the distance between the opposing position control railings, the cargo must be placed on the position control railing and then tied down with a rope or a worker must support the rear, making it inconvenient to transport large cargo volumes.

[0005] In the prior art, a utility model with Chinese registration publication number CN215286043U discloses an adjustable-size battery mounting box, in which the first mounting box and the second mounting box have the same structure, both consisting of a bottom plate, a back plate and an intermediate partition plate, with multiple intermediate partition plates movably attached to the back plate, the back plate and bottom plate being divided into multiple mounting chambers by the intermediate partition plates, which slide along the back plate to adjust the size of the mounting chambers, and fixing screw holes are further installed at the ends of the intermediate partition plate, and fastening bolts are installed in the fixing elongated holes, and the fastening bolts are installed in the fixing screw holes to fix the intermediate partition plate to the back plate.

[0006] In the prior art cited above, the size of the loading chamber is adjusted using an intermediate partition plate, and in the process of adjusting the intermediate partition plate, the intermediate partition plate is fixed with a tightening bolt, and the tightening bolt needs to be operated before and after moving the intermediate partition plate, which makes it difficult to install quickly and makes operation inconvenient. Summary of the Invention [Problem to be solved by the invention]

[0007] The objective of the present invention is to provide an electric tricycle with a new carrier and battery box structure, thereby resolving the aforementioned problems of the currently available electric tricycles in the background art, such as the inconvenience of loading large objects and quickly dividing the space. [Means for solving the problem]

[0008] In order to achieve the above objectives, the present invention provides a technical solution for an electric tricycle with a new carrier and battery box structure, which: a mounting plate welded to the inside of the frame, with a fixing bar welded to the lower end of the frame and a fence inserted into the end of the fixing bar; a connecting bar located at the right end of the frame, with a front wheel rotatably connected to the lower left corner thereof and a rear wheel attached to the lower right end of the frame; The electric tricycle further includes a fence and a battery box body. The fence is positioned around the frame. An extension mechanism is installed between the fence and the fixed bar to enable the fence to be extended or retracted. The telescopic mechanism adjusts the extension of the fence depending on the size of the belongings. The battery box body engages with the right end of the frame. Inside the battery box body, an adjustment mechanism is installed that slides to easily accommodate different storage batteries.

[0009] Preferably, the telescopic mechanism includes through holes that are equally spaced apart on both sides of the lower end of the fence, and both sides of the lower end of the fence protrude into the fixed bar, which is installed in a hollow cylindrical structure.

[0010] Preferably, a bolt module including a bolt and a nut is threadedly attached to both sides of the lower end of the fixing bar, the nut is located at the lower end of the fixing bar, and the bolt is inserted into the through hole and the fixing bar.

[0011] Preferably, holes are uniformly formed on the upper end of the support plate, and the depth of the holes is the same as the thickness of the support plate. A plurality of intersecting support bars are welded to the lower end of the frame, and the upper ends of the support bars are attached to the lower end of the support plate.

[0012] Preferably, a push handle is inserted through the upper end of the connecting bar. A grip is attached to the right end of the push handle. A control member is installed to the left side of the grip. The control member allows the tricycle to move.

[0013] Preferably, a connection device is installed at the left end of the battery box body, a controller is disposed at the front side inside the battery box body, and the adjustment mechanism includes a partition plate that engages with an insertion groove inside the battery box body.

[0014] Preferably, two sets of the insertion grooves are provided inside the battery box body, and each set of the insertion grooves consists of three insertion grooves.

[0015] Preferably, a baffle plate is engaged with the right end of the rear partition plate. A horizontal plate is engaged between the front and rear partition plates. The horizontal plate is installed horizontally. The length of the horizontal plate is longer than the maximum distance between the front and rear insertion grooves.

[0016] Preferably, a storage battery is placed above the horizontal plate. The storage battery is electrically connected to a controller. The controller is electrically connected to a connection device. The two left and right parts of the battery box body are engaged and fixed.

[0017] Preferably, the push handle has grooves at equal intervals on its outer surface. The grooves have a thickness smaller than the radius of the push handle. A screw is threadedly attached to the right end of the connecting bar. The left end of the screw is inserted into the connecting bar.

[0018] Compared with the prior art, the present invention has the following significant advantages: it can adjust the cargo carrying space of the electric tricycle, accommodate batteries of different specifications, and quickly divide the battery carrying space, thereby improving work efficiency. 1. The fence can slide inside the fixed bar, and the fence can move to the appropriate bolt module and be fixed by this bolt module. The surrounding fence is expandable, so the size of the space formed by the four fences can be changed according to the size of the object. The fence contacts the cargo and restricts it, reducing the swaying of the cargo while the electric tricycle is moving and reducing the workload of the workers. 2. The push handle slides onto the connecting bar and can be fixed with a screw, which fixes the grip position and allows the operator to adjust it according to their own height before pushing the electric tricycle, making it easier to control the direction of the electric tricycle when supporting it. 3. The partition plates can be inserted directly into the insertion grooves. Each set of insertion grooves consists of three insertion grooves, so the distance between the two left and right partition plates can be adjusted according to the volume of the storage battery. This allows batteries of different specifications to be used in the electric box body, and the process of dividing the space can be done simply by inserting the partition plates into the insertion grooves, allowing for quick change of space. 4. The horizontal plate is fitted inside the two front and rear baffle plates to divide the space formed by the two plates. A small-volume battery can be stored above the horizontal plate, and the upper end of the battery is positioned accordingly. This prevents the battery from shaking when the electric tricycle travels over uneven ground, and prevents the battery from colliding with the battery box body, protecting the battery. 5. The mounting plate is equipped with holes, so if dirt remains on the mounting plate, it can be washed directly. The washed-out mounting plate leaves little moisture, shortening the drying time. The electric tricycle does not require pushing by the operator while in use, reducing the workload. The operator only needs to support the electric tricycle during use.

[0020] The following will more clearly and comprehensively describe the technical solutions in the embodiments of the present invention with reference to the drawings of the embodiments of the present invention. The described embodiments are not all of the embodiments of the present invention, but only some of the embodiments of the present invention. All other embodiments that can be obtained by those skilled in the art based on the embodiments of the present invention without creative work should fall within the scope of protection of the present invention.

[0021] Referring to FIGS. 1 to 8, the technical solution of the present invention is as follows. Example 1 To solve the problem of the prior art that it is difficult to divide the space quickly, the following technical solution is disclosed. Specifically, as shown in FIGS. 2-3 and 6-7, a battery box body 7 is engaged with the right end of the frame 1. An adjustment mechanism that slides to easily accommodate different storage batteries is installed inside the battery box body 7. A connection device 10 is installed at the left end of the battery box body 7. A controller 11 is disposed at the front side inside the battery box body 7. The adjustment mechanism includes a partition plate 12 that engages with an insertion groove inside the battery box body 7.

[0022] Two sets of insertion grooves are provided inside the battery box body 7. Each set of insertion grooves consists of three insertion grooves.

[0023] A baffle plate 13 is engaged with the right end of the rear partition plate 12. A horizontal plate 14 is engaged between the front and rear partition plates 12. The length of the horizontal plate 14 is longer than the maximum distance between the front and rear insertion grooves.

[0024] A storage battery electrically connected to the controller 11 is placed above the horizontal plate 14. The controller 11 is electrically connected to the connection device 10. The two left and right portions of the battery box body 7 are engaged and fixed.

[0025] Grooves 16 are formed at equal intervals on the outside of the push handle 4. The thickness of the grooves 16 is smaller than the radius of the push handle 4. A screw 6 is threadedly attached to the right end of the connecting bar 15. The left end of the screw 6 is inserted into the connecting bar 15. The travel distance of the connecting bar 15 is longer than the maximum distance from the left end of the connecting bar 15 to the push handle 4.

[0026] Before inserting the batteries, the left and right halves of the battery box body 7 are separated, and the positions of the front and rear partition plates 12 are changed depending on the size of the batteries, and the partition plates 12 are fitted into the appropriate insertion grooves. Whether or not to engage the side plates 14 can be selected depending on the height of the batteries. If the volume of the batteries is small, the side plates 14 can be fitted to the left ends of the front and rear baffle plates 13, and two batteries can be placed inside the battery box body 7 and above the side plates 14, respectively. Then, the circuits of the batteries, controller 11, and connection device 10 are connected, and the electrical device is operated by the batteries.

[0027] Example 2 To solve the problem of difficulty in placing large objects in the prior art, the present invention specifically includes a mounting plate 2 welded to the inside of a frame 1, a connecting bar 15 located at the right end of the frame 1, and an extension mechanism with through-holes equally spaced on both sides of the lower end of a fence 3, as shown in FIGS. 1 and 5 . A fixed bar 18 is welded to the lower end of the frame 1. The fence 3 is inserted into the end of the fixed bar 18. A front wheel is rotatably connected to the lower left corner of the connecting bar 15. A rear wheel 9 is attached to the lower right end of the frame 1. Both sides of the lower end of the fence 3 protrude into the fixed bar 18. The fixed bar 18 has a hollow cylindrical structure. Bolt modules 17, each including a bolt and a nut, are threadedly attached to both sides of the lower end of the fixed bar 18. The nuts are located at the lower end of the fixed bar 18. The bolts are inserted into the through-holes and into the fixed bar 18. The nut of the bolt module 17 is manually rotated until the nut and bolt module 17 are separated from the through-hole, and the grip 5 is manually pulled outward or pushed inward until the lower end position of the grip 5 slides inside the fixed bar. After the grip 5 has moved to the appropriate position, the nut is manually rotated, and the bolt is rotated synchronously as the nut is rotated. The bolt rotates and moves upward until it is inserted into the through-hole, thereby fixing the fence 3. After the nut can no longer rotate, they come into contact with the outside of the fixed bar 18, and then the bolt module 17 can no longer rotate, thereby fixing the fence 3.

[0028] Example 3 A new technical solution has been added based on Example 2, allowing the user to adjust the height of the grip 5 according to their height. Specifically, as shown in Figures 1 and 4-5, in this electric tricycle with a new carrier and battery box structure, a fence 3 is positioned around the frame 1, and a telescopic mechanism is installed between the fence 3 and a fixed bar 18 to allow the fence 3 to extend or retract. The telescopic mechanism adjusts its extension or retraction depending on the size of the belongings being carried. Holes are uniformly drilled at the top end of the loading plate 2, with the depth of the holes being the same as the thickness of the loading plate 2. A number of intersecting support bars are welded to the bottom end of the frame 1, and the top ends of the support bars are attached to the bottom end of the loading plate 2. A push handle 4 is inserted into the top end of the connecting bar 15, a grip is attached to the right end of the push handle 4, and a control member for driving the tricycle is installed to the left side of the grip 5. The screw 6 is manually rotated, and as the screw 6 rotates, it moves synchronously left and right; when the screw 6 rotates to the right, the left end of the screw 6 gradually separates from the groove 16. After the left end of the screw 6 completely separates from the groove 16, the push handle 4 is manually pulled upward, and the push handle 4 is moved upward until it reaches the appropriate height. The screw 6 is then manually reversed, and as the screw 6 reverses, it moves synchronously to the left, and the screw 6 moves toward the left and into the groove 16, and the screw 6 is rotated until it can no longer rotate. In this way, the position of the push handle 4 is regulated by the screw 6, and the positions of the push handle 4 and the grip 5 are also regulated, so that the operator can control the electric tricycle by operating the grip 5. This eliminates the need for the operator to push the electric tricycle, reducing the operator's workload and making it easier to control the traveling speed. By providing the holes in the mounting plate 2, when a user cleans the mounting plate 2, the amount of water remaining on the mounting plate 2 is small, and the drying time of the mounting plate 2 is shortened.

[0029] Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art may modify the technical solutions described in the above embodiments or replace some technical features with equivalents, and all modifications, equivalent replacements, improvements, etc. made without departing from the spirit and principles of the present invention are included in the protection scope of the present invention.
