Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic brakes, and relates to an electromagnetic brake, particularly a hollow through-axle type electromagnetic brake for a mobility scooter. Background Technology

[0002] With the development of technology, electric mobility scooters have emerged to facilitate short-distance travel. These scooters are equipped with electromagnetic braking devices, which allow them to decelerate and brake using the vehicle's electrical energy.

[0003] Existing electromagnetic brakes typically involve inserting a drive shaft into the brake disc, thus fixing the brake disc to the drive shaft. Braking is then achieved through friction between the brake pads and the brake disc. However, this structure limits the installation location of the electromagnetic brake and also increases the required installation space, necessitating a larger size for the mobility scooter. Additionally, the small battery capacity of the mobility scooter may lead to power outages during operation. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an electromagnetic brake for a mobility scooter that achieves mechanical braking by inserting a hollow spring through an axle inside the electromagnetic brake.

[0005] This utility model can be achieved through the following technical solution: a hollow through-axle type electric brake for a mobility scooter, including a grooved disc and a brake structure. The brake structure includes a brake disc, an upper friction plate, and a lower friction plate. A through hole is opened in the grooved disc, and a spring fixing post is installed in the through hole. A hollow spring is arranged between the spring fixing post and the grooved disc, and a trigger is installed on the outside of the hollow spring.

[0006] In the aforementioned hollow through-axle type electric brake for mobility scooters, a steel ball is provided inside the trigger, and a groove is provided on the slotted plate.

[0007] In the aforementioned hollow through-axle type electric brake for mobility scooters, a slot is provided on the spring fixing post, and a retaining spring is installed in the slot.

[0008] In the aforementioned hollow through-axle type electric brake for mobility scooters, a wave-shaped shim is provided between the retaining ring and the trigger.

[0009] In the aforementioned hollow through-axle type electric brake for personal mobility vehicles, a base plate is provided on the outside of the trigger.

[0010] Compared with the prior art, the advantages of this utility model are as follows: by opening through holes in the slotted plate, the power shaft can be inserted through the slotted plate side and the brake structure side and connected to the brake disc to realize the braking function; the spring fixing column can drive the friction plate to contact the brake disc through the movement of the trigger and the push of the hollow spring to realize manual braking.

[0012] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0013] like Figure 1 and Figure 2 As shown, this utility model can be implemented through the following embodiments: a hollow through-axle type electric brake for a mobility scooter, including a grooved plate 1 and a brake structure 2. The brake structure 2 includes a brake disc 21, an upper friction plate 22 and a lower friction plate 23. A through hole 11 is opened in the grooved plate 1. A spring fixing post 3 is installed in the through hole 11. A hollow spring 4 is arranged between the spring fixing post 3 and the grooved plate 1. A trigger 5 is installed on the outside of the hollow spring 4.

[0014] Brake structure 2 is used to connect with the drive shaft. Braking is achieved by clamping the brake disc 21 connected to the drive shaft with the upper friction plate 22 and the lower friction plate 23. The opening of the through hole 11 allows the drive shaft to pass into the electromagnetic brake from the end of the slot plate 1, reducing the installation space for installing the electromagnetic brake. The spring fixing post 3 contacts the lower friction plate 23 and is used to push the lower friction plate 23 to close with the brake disc 21 and the upper friction plate 22 by its own movement, thereby achieving mechanical braking. The hollow spring 4 is used to push the spring fixing post 3 to move towards the brake disc 21. The trigger 5 is used to release the movement space of the spring fixing post 3 or to reset the spring fixing post 3.

[0015] like Figure 1 As shown, a steel ball 51 is provided inside the trigger 5, and a groove 12 is provided on the slotted plate 1. The steel ball 51 is used to support the trigger 5, so that there is a certain gap between the trigger 5 and the slotted plate 1, preventing the electromagnetic brake from activating due to the push of the spring fixing post 3 by the hollow spring 4; the groove 12 is used to accommodate the steel ball 51, so that the trigger 5 fits against the slotted plate 1, and the spring fixing post 3 has room to move; the setting of the steel ball 51 changes the sliding friction between the trigger 5 and the slotted plate 1 into rolling friction, which facilitates the sliding of the trigger 5.

[0016] like Figure 1 and Figure 2As shown, the spring fixing post 3 is provided with a slot 31, and a retaining spring 32 is installed in the slot 31. The slot 31 is used to install the retaining spring 32, and the retaining spring 32 is used to contact the trigger 5, so that the displacement of the spring fixing post 3 is restricted by the trigger 5, preventing the friction plate 23 from moving on its own by pushing the spring fixing post 3.

[0017] like Figure 1 and Figure 2 As shown, a wave-shaped shim 6 is provided between the retaining ring 32 and the trigger 5. The wave-shaped shim 6 is used to fill the gap between the retaining ring 32 and the trigger 5 to prevent noise during braking.

[0018] like Figure 1 As shown, a base plate 7 is provided on the outside of the trigger 5. The base plate 7 is used to cover the trigger 5 and to provide support for the drive shaft that passes through the slot 1, ensuring a stable connection between the brake disc 21 and the drive shaft.

[0019] The working principle of this utility model is as follows: When manual braking is required, the trigger 5 is pulled and the trigger 5 is in the braking position. The steel ball 51 fits into the groove 12, so that there is a gap between the snap ring 32 and the trigger 5. The hollow spring 4 pushes the spring fixing post 3 to move, so that the spring fixing post 3 pushes the lower friction plate 23 to move, thereby making the lower friction plate 23 contact the brake disc 21 and the upper friction plate 22 to achieve braking.

[0020] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0021] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
