Description

Technical Field

[0001] This utility model relates to the field of electric vehicle frame technology, specifically a retractable electric vehicle frame. Background Technology

[0002] In the current community management system, due to the standardized management of electric vehicles, the designated parking spaces are often unsuitable for the large size of electric vehicles, making it difficult to meet the needs of standardized community parking. Therefore, there is a need for a retractable electric vehicle frame that can solve the storage problem and is easy to control.

[0003] Chinese utility model patent application CN221541827U discloses a retractable electric vehicle frame and an electric vehicle, relating to the field of electric vehicle technology. The retractable electric vehicle frame includes: a retractable electric vehicle frame body, a frame control module, and an environmental sensing module. The frame control module and the environmental sensing module are mounted on the retractable electric vehicle frame body and are communicatively connected. The environmental sensing module collects environmental data from the external environment, and the frame control module unfolds or retracts the retractable electric vehicle frame body under the control of the environmental data. This utility model can automatically unfold or retract the retractable electric vehicle frame according to the external environment, making travel more convenient for users. However, this device does not solve the problems of easy free extension and retraction and improved carrying and storage space. Therefore, we propose a retractable electric vehicle frame. Utility Model Content

[0004] The purpose of this invention is to provide a retractable electric vehicle frame to solve the problems mentioned in the background art, such as the inability to achieve easy retraction and extension and improve the carrying and storage space.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A retractable electric vehicle frame includes a fixed base. A main body mechanism is fixedly mounted on the top of the fixed base, and a moving mechanism is movably mounted on the bottom of the main body mechanism. The main body mechanism includes a front frame. The front frame, a first set of limiting rods, and a device mounting frame are fixedly mounted on the top of the fixed base. The first set of limiting rods is fixedly mounted on one side of the front frame. The device mounting frame is fixedly mounted on the other side of the first set of limiting rods away from the front frame. A second set of limiting rods is movably mounted on the other side of the device mounting frame away from the first set of limiting rods. A rear frame is fixedly mounted on the other side of the second set of limiting rods away from the device mounting frame.

[0007] Preferably, the top of the front frame has a battery mounting slot, and a dust cover is movably mounted on the top of the battery mounting slot. The dust cover is mounted on the top of the battery mounting slot by a set of fixing bolts. The battery mounting slot has a circular hole, and a Y-shaped mounting rod is movably mounted inside the circular hole. A frame handle is fixedly mounted on the top of the Y-shaped mounting rod, and a controller is fixedly mounted on the top of the frame handle. The dust cover facilitates better mounting on the top of the battery mounting slot by the set of fixing bolts.

[0008] Preferably, a first set of electric push rods is fixedly installed inside the device mounting frame. The output end of the first set of electric push rods is fixedly connected to one end of the first set of limiting rods near the device mounting frame, and the output end of the second set of electric push rods is fixedly connected to one end of the second set of limiting rods near the device mounting frame. The first set of electric push rods drives the first set of limiting rods to extend towards one end of the Y-shaped mounting rod, and the second set of electric push rods drives the second set of limiting rods to extend towards the side of the supporting sub-seat cushion, thereby extending the distance between the front frame and the rear frame.

[0009] Preferably, a second set of electric push rods is fixedly installed on one side of the first set of electric push rods. The first set of limiting rods, the first set of electric push rods, the second set of limiting rods, and the second set of electric push rods are parallel to each other and axially symmetrical. Four I-shaped plates are fixedly installed in the middle of the first set of limiting rods and the second set of limiting rods. In normal use, it is often necessary to carry items. In the process of expansion, the storage space between the first set of limiting rods, the second set of limiting rods, and the device mounting frame is expanded.

[0010] Preferably, a main vehicle seat is fixedly installed on the top of the rear frame, a supporting secondary seat is fixedly installed on one side of the main vehicle seat, and two sets of supporting collars are fixedly installed on both sides of the supporting secondary seat. Two fixed spindles are movably installed inside each of the two sets of supporting collars. Two connecting secondary seat cushions are movably installed on the side of the two fixed spindles away from the supporting secondary seat cushion. The angle of the two connecting secondary seat cushions can be freely rotated and adjusted on both sides of the supporting secondary seat cushion through the fixed spindles. When it is necessary to use the supporting secondary seat cushion to carry large luggage, the user manually rotates the fixed spindle to rotate the two connecting secondary seat cushions and adjusts them to be parallel to the supporting secondary seat cushion for transporting large goods.

[0011] Preferably, the action mechanism includes a front wheel and a rear wheel. The front wheel is located at the bottom end of the Y-shaped mounting rod, and the rear wheel is movably mounted on one side of the front wheel. The rear wheel is located at the bottom end of the rear frame. When using the telescopic electric vehicle frame for free movement, the user holds the frame handle, and the combination design of the front wheel and the rear wheel driving the electric vehicle frame to move freely achieves the purpose of facilitating free movement of the telescopic electric vehicle frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This retractable electric vehicle frame, when it needs to be extended or retracted, the user first controls the controller, then the first set of electric push rods drives the first set of limit rods to extend towards one end of the Y-shaped mounting rod, and the second set of electric push rods and the second set of limit rods extend towards the side of the supporting sub-seat, thereby extending the distance between the front frame and the rear frame. In normal use, it is often necessary to carry items, and during the extension process, the storage space between the first set of limit rods, the second set of limit rods and the device mounting frame is expanded. When it is necessary to use the supporting sub-seat to carry large luggage, the user manually rotates the fixed spindle to drive the two connecting sub-seats to rotate, adjusting them to be parallel to the supporting sub-seat for transporting large goods. The combination design realizes that the retractable electric vehicle frame can be freely extended and retracted and improves the carrying and storage space capacity.

[0014] 2. This retractable electric vehicle frame, when used for free movement, allows the user to hold the frame handle and move the electric vehicle frame freely through the front and rear wheels, thus achieving the purpose of facilitating free movement of the retractable electric vehicle frame.
