DETAILED DESCRIPTION

[0030] See also Figures 1 to 3A movable electric vehicle controller test platform includes a mobile base 1, one side of the top of the mobile base 1 is provided with a hub shaft fixing component 10 for fixing the electric bicycle hub, the left end of the upper side of the mobile base 1 is fixedly connected to the electric vehicle hub support box 2, two data display screens 5 are inlaid on the upper side of the electric vehicle hub support box 2, and a plurality of operation control knobs 6 are inlaid on the upper side of the electric vehicle hub support box 2, the right end of the upper side of the mobile base 1 is fixedly connected to a hub placement recess 7, and the upper side of the hub placement recess 7 is fixedly connected to four mounting plates 9 that are compatible with the hub shaft fixing component 10.

[0031] Among them, a baffle 11 is hinged on the right side of the mobile base 1, and a removable end plate 3 is bolted to the front end face of the electric vehicle hub support box 2. A circuit hole 4 is provided inside the lower side of the removable end plate 3, and one side of the mounting plate 9 is detachably connected to the electric vehicle handlebar mounting tube 8. A plurality of wires are connected to the lower side of the operation control knob 6, and a plurality of wires are sleeved inside the electric vehicle hub support box 2. A circuit hole 4 is provided inside the lower side of the removable end plate 3, and the wires are moved out of the circuit hole 4 and extended to the outside. Two data display screens 5 are arranged horizontally, and the output end of the data display screen 5 is fixedly connected to one end of the wire, and the output end of the operation control knob 6 is fixedly connected to one end of the wire. A groove is provided inside the upper side of the fixed plate 12, and the hub placement recess 7 is a U-shaped plate structure. The four mounting plates 9 are respectively fixedly connected to the four corners of the top of the hub placement recess 7.

[0032] It should be noted that the interior of the mobile base 1 is a hollow structure, and some infrequently used maintenance tools can be placed inside. Daily, the tools in the inner cavity of the mobile base 1 can be taken out by opening the baffle 11. A plurality of rollers are bolted to the lower side of the mobile base 1, and a brake pad is fixedly connected to the upper end of each roller. The detachable end plate 3 is bolted to one end surface of the electric vehicle hub support box 2. The line can be removed from the line hole 4 and electrically connected to other controllers. At the same time, the line can also be used to transmit data to the data display screen 5, which is convenient for subsequent observers to better view. The wires are used to transmit the data and control the hub shaft fixing component 10. The wires are removed from the circuit hole 4 and can be connected to other devices to facilitate the control of data transmission. The data display screen 5 can view the hub data results more intuitively. The groove can plug and fix the hub's rotating shaft inside the upper side of the fixing plate 12, which is convenient for fixing and supporting the hub shaft to avoid shaking. The U-shaped structure of the hub placement recess 7 is convenient for avoiding the hub with tire, and can also be used as a placement platform to allow the hub tire to be directly placed in to play a supporting role.

[0033] The working principle of a roller is primarily based on energy conversion, specifically the conversion between kinetic energy and elastic potential energy. Taking the Hooke roller as an example, its operating principle can be summarized as follows: when a hand pushes the roller, it is given an initial kinetic energy—the hand push initiates the movement. As the roller rolls, internal mechanisms, such as the suspended nut and rubber band, convert this kinetic energy into elastic potential energy. During this process, the rubber band continuously twists and deforms, storing energy. When the roller is about to stop rolling, the rubber band untwists, releasing the stored elastic potential energy and driving the roller in the opposite direction. This allows the roller to continuously convert between kinetic energy and elastic potential energy, enabling it to roll back and forth. The working principle of a roller brake pad is similar to that of a car's braking system, primarily utilizing friction to achieve braking. A roller brake consists of multiple layers. When the innermost gear-shaped steel ring rotates, it lifts each cylindrical steel ball, increasing the diameter of the second layer. This increased diameter then forces the steel balls into contact with the third layer, increasing the diameter of the brake pad. Finally, this forces the brake pad into contact with the outermost brake drum, achieving the desired braking effect. This graded braking method can make the vehicle brake more smoothly during driving and prevent the wheels from slipping suddenly. The roller brake pads generate friction through contact with the brake drum or brake disc. During the braking process, the brake pads are clamped and pressed against the brake drum or brake disc. Due to the effect of friction, the kinetic energy of the vehicle is converted into heat energy and consumed, thereby achieving the braking effect.

[0034] It's important to note that the operating principle of roller brake pads can vary depending on the specific design and application. For example, in some cases, roller brake pads may be implemented as a disc brake system, where the brake pads are clamped by the brake caliper and press against the brake disc to generate friction. In other cases, roller brake pads may be implemented as a drum brake system, where the brake pads contact the brake drum to generate friction.

[0035] See also Figures 1 to 3 In this embodiment, the hub shaft fixing component 10 includes a fixing plate 12 bolted to one side of the mounting plate 9, a hub shaft positioning threaded rod 13 threadedly connected to the upper side of the fixing plate 12, an internal block push rod 14 slidingly sleeved on the upper side of the fixing plate 12, and a block 15 fixedly connected to one end of the block push rod 14.

[0036] Among them, the block 15 can indirectly check the bearing capacity, rotation accuracy and durability of the bearing by contacting the hub shaft. If there is a problem with the bearing, such as wear, looseness or damage, abnormal sound, vibration or increased resistance may be generated during contact. By contacting the block 15 with the hub shaft and observing the rotation of the hub, it is possible to detect whether the hub has a runout problem. Excessive runout will lead to increased tire wear, increased vehicle vibration, and even affect driving safety. By contacting the block 15 with the hub shaft, it is possible to check whether the hub is firmly installed on the vehicle and whether there are any loose or misaligned problems. These problems may cause the hub to fall off or be damaged during driving, thereby causing traffic accidents. By contacting the block 15 with the hub shaft and observing the rotational stability of the hub, the dynamic balance performance of the hub can be evaluated. A hub with poor dynamic balance performance will lead to increased vehicle vibration and uneven tire wear.

[0037] The working principle of the above embodiment is:

[0038] First, observe the size of the electric vehicle wheel hub, and adjust the spacing between the two relative hub axle fixing components 10 on the side of the mounting plate 9 through bolts to keep the two hub axle fixing components 10 in contact and fixed with the hub axle. Then, pass the hub axle of the wheel hub through the two hub axle fixing components 10. In order to avoid the wheel hub from shaking, rotate the hub axle positioning threaded rod 13 and use the threaded structure to move it toward the side of the fixing plate 12 until the hub axle positioning threaded rod 13 contacts the upper side of the hub axle, which can effectively prevent the hub axle from moving up and down. Then, according to the diameter of the hub axle, cooperate with the block push rod 14 to push the block 15 into contact. The bottom of the fixed hub is suspended on the upper side of the hub placement recess 7. The hub placement recess 7 can effectively play a role of avoidance, and when the hub is not in use, the hub can be directly placed on the upper side of the hub placement recess 7. Finally, it is only necessary to control the operation control knob 6 to start and drive the hub shaft. The block 15 can indirectly know the load-bearing capacity, rotation accuracy and durability of the hub by contacting the hub shaft. If there is a problem with the bearing, such as wear, looseness or damage, abnormal sound, vibration or increased resistance may be generated during contact. The final result will be transmitted to the data display screen 5 for direct viewing by the staff.
