[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0036] The aforementioned and other technical aspects, features, and functions of the present invention will be more clearly demonstrated in the following detailed description of the embodiments with reference to the accompanying drawings. Directional terms such as up, down, left, right, front, and back, used in the following embodiments, are merely references to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes only and are not intended to limit the present invention. Furthermore, throughout the embodiments, identical reference numerals denote identical components.

[0037] The structure of an existing electric bicycle (e-bike) mainly consists of the following parts: 1. A frame, which is usually made of metal (such as aluminum alloy) or carbon fiber to provide stable structural support and load-bearing capacity, and is equipped with a front wheel 401 and a rear wheel 402; 2. An electric motor, which is usually installed in the center of the frame to provide power drive, and common types include a central drive motor, a rear wheel drive motor, and a front wheel drive motor; 3. A battery 200, which is usually installed on the rear rack 403 of the frame and is used to store electrical energy for use by the motor, and can be used through the handle 201 (such as the handle 201) of the battery 200. Figure 3 The battery can be removed from the rear hanger 403. The battery can be a lithium battery, nickel-metal hydride battery, or similar. Fourth, the control system, which typically includes a controller, display, and handle. The controller controls the speed and power output of the motor, the display shows information such as battery level, speed, and mileage, and the handle controls acceleration and braking. Fifth, the transmission system, typically consisting of a chain and gears, transmits the power of the motor to the wheels, enabling forward and reverse movement.

[0038] However, existing battery handle durability testing methods primarily rely on manual operation, simulating user usage scenarios by repeatedly pulling and rotating the battery handle to test its durability and stability. While this method can provide a certain degree of accuracy in determining the durability of the battery handle, the test results lack accuracy and repeatability, and the test efficiency is low.

[0039] In order to solve the above problems, this embodiment provides a testing device for testing the durability of the battery handle of the rear clothes hanger of an e-bike.

[0040] Combine Figure 1 and Figure 2As shown, a test device for testing the durability of the battery handle of the rear hanger of an e-bike comprises:

[0041] A fixing mechanism 100, used for fixing the electric-assisted bicycle 400 to be tested;

[0042] The lifting mechanism 300 is arranged near the rear clothes hanger 403 of the electric assisted bicycle 400 and is arranged on the fixing mechanism 100; the lifting mechanism 300 includes at least one lifting drive source 301 and a lifting component that can contact the active end of the lifting drive source 301; the lifting component includes a connector 303 that is clamped with the battery 200 of the electric assisted bicycle 400.

[0043] In this embodiment, the fixing mechanism 100 includes a base 101, a first bracket 102, a second bracket 103 and a support body 104. The first bracket 102, the second bracket 103 and the support body 104 are installed on the base 101 in sequence along the length direction of the base 101; the first bracket 102 is used to fix the front wheel 401 of the electric assisted bicycle 400; the second bracket 103 is used to fix the rear wheel 402 of the electric assisted bicycle 400; the support body 104 is used to install the lifting mechanism 300.

[0044] Furthermore, the height of the first bracket 102 and the height of the second bracket 103 are both adjustable. The adjustment method can be achieved by replacing the first bracket 102 and the second bracket 103 with different heights, so as to adapt to different models of electric-assisted bicycles 400.

[0045] The support body 104 is a frame structure. Specifically, the support body 104 is composed of a plurality of beams and a plurality of columns.

[0046] It can be understood that the front wheel 401 of the electric assisted bicycle 400 is fixed by the first bracket 102, and the rear wheel 402 of the electric assisted bicycle 400 is fixed by the second bracket 103. The tires of the front wheel 401 and the rear wheel 402 are on the ground, and the parking of the electric assisted bicycle 400 is simulated in practice.

[0047] In this embodiment, combined with Figure 4 and Figure 5The lifting assembly also includes a second fixed plate 308 supporting a lifting drive source 301, a first fixed plate 302 for mounting a connector 303, at least one sliding assembly slidably connected to the first fixed plate 302, and a vertical plate 307 for fixing the sliding assembly and fixedly connected to the second fixed plate 308; wherein the connector 303 and the sliding assembly are respectively arranged on both sides of the first fixed plate 302. There are two lifting drive sources 301, and the two lifting drive sources 301 are symmetrically arranged about the central axis of the second fixed plate 308, which can increase the lifting speed, which is the same as the lifting and moving actions of the user in the actual process. The lifting drive source 301 can use a commercially available cylinder, and the model of the cylinder can be selected and adjusted by technicians in this field according to needs.

[0048] Specifically, the connecting member 303 includes a first connecting portion 3031 and a second connecting portion 3032 . The first connecting portion 3031 can at least partially extend into the groove of the handle 201 of the battery 200 . The second connecting portion 3032 is fixedly connected to the first fixing plate 302 .

[0049] The sliding assembly includes a sliding member 304 fixedly connected to the first fixed plate 302 , a guide rail 306 fixed to the vertical plate 307 , and a slider 305 sliding along the guide rail 306 ; the sliding member 304 is fixed to the slider 305 .

[0050] Furthermore, the lifting assembly also includes a limiting assembly, one side of which abuts the first fixing plate 302 and the other side of which is fixed to the second fixing plate 308. Specifically, the limiting assembly includes a support member 310 fixed to the second fixing plate 308 and disposed between the two lifting drive sources 301, and an actuating member 311 disposed on the support member 310. The support member 310 can be a rib plate.

[0051] Furthermore, a reinforcement member 309 may be provided between the first fixing plate 302 and the sliding member 304 , and the reinforcement member 309 increases the strength between the first fixing plate 302 and the sliding member 304 .

[0052] In other possible embodiments, the testing device further includes weights, which are fixed above the rear hanger 403. The purpose of providing the weights is to facilitate fixing and removing to change the load and to prevent the electric bicycle 400 from tilting during the test.

[0053] In other possible embodiments, the testing device also includes a temperature and humidity test box with adjustable temperature and humidity. The fixing mechanism 100, the lifting mechanism 300 and the electric assisted bicycle 400 are all installed in the temperature and humidity test box, so that different test conditions can be set as needed, such as changing the temperature or humidity, to comprehensively evaluate the durability and stability of the handle 201 under various environments and usage conditions.

[0054] The working principle of this utility model is as follows:

[0055] The lifting component is pushed upward by the lifting drive source 301. Specifically, the action end of the lifting drive source 301 pushes the first fixed plate 302, and the first fixed plate 302 slides along the sliding component. The first fixed plate 302 drives the handle 201 of the battery 200 to lift through the connecting member 303, simulating the action of a person lifting the handle 201 of the battery 200.

[0056] When the lifting drive source 301 is not working, the electric assisted bicycle 400 falls freely, and the limiting component is used to limit the descending position of the electric assisted bicycle 400, simulating the action of the user putting down the electric assisted bicycle 400; it should be noted that the lifting drive source 301 is not rigidly connected to the lifting component, and the descent can satisfy free fall without being interfered by the lifting drive source 301.

[0057] As can be seen from the above, compared with the existing technology, the beneficial effects of this embodiment are as follows:

[0058] First, it can accurately simulate the user's pulling motion on the handle 201 during riding, thereby more accurately evaluating the durability and stability of the handle 201 of the battery 200. Compared to existing manual testing methods, the testing device provided in this embodiment provides results that are closer to real-world usage scenarios and have higher accuracy and repeatability.

[0059] Second, using automated testing can greatly improve test efficiency and meet the needs of large-scale production. Compared with existing manual testing methods, the testing device provided by this embodiment can complete a large number of tests in a short period of time, greatly improving test efficiency.

[0060] Third, different test conditions can be set as needed, such as temperature, humidity, load, etc., to comprehensively evaluate the durability and stability of the handle 201 of the battery 200 under various environments and usage conditions. Compared to existing testing methods, the testing device provided in this embodiment can more comprehensively evaluate the quality level of the handle 201 of the battery 200.

[0061] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific contexts.

[0062] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
