Description

Technical Field

[0001] This application belongs to the field of motor technology, specifically relating to an electric roller shutter cover motor with a braking structure. Background Technology

[0002] As a vehicle that combines cargo and passenger functions, pickup trucks prioritize cargo security and space utilization in their cargo beds. To prevent cargo theft without excessively encroaching on cargo space, power-operated roll-up covers, driven by a motor for automated opening and closing, have become a mainstream feature. These devices must possess reliable self-locking capabilities when stationary to prevent accidental opening due to vibrations or other external forces while the vehicle is in motion. Simultaneously, they must minimize their structural impact on cargo bed space, placing stringent demands on the performance and structural design of the drive motor.

[0003] The self-locking function of existing electric roller shutter motors mainly relies on a worm gear structure: In traditional solutions, some motors use a worm gear structure with the output shaft parallel to the worm, utilizing the locking characteristics of both to achieve self-locking and restrict the movement of the roller shutter slats. However, this structure needs to be parallel to the roller shutter shaft when arranged in the vehicle, resulting in a significant increase in the volume of the roller shutter housing and severely compressing the cargo box storage space. To optimize space, another solution designs the motor output shaft and worm as a vertical structure, which greatly reduces the space occupied in the cargo box, but changes the contact state between the worm gear and the worm, bringing new challenges to the self-locking performance.

[0004] Shortcomings of existing technology:

[0005] 1) In a motor structure where the output shaft is perpendicular to the worm, the contact area between the worm wheel and the worm is prone to significant changes when traveling on vibrating surfaces. When the contact area decreases and the motor is subjected to external vibration, the frictional self-locking force between the two is insufficient, making relative rotation likely. This can cause the motor to fail to reliably self-lock, potentially resulting in the roller shutter cover being shaken open and posing a risk of goods theft.

[0006] 2) Traditional structures that rely on worm gear self-locking, if the output shaft is parallel to the worm to ensure self-locking performance, will significantly increase the volume of the roll-up cover box and affect the storage space of the cargo box; if a vertical structure is adopted to save space, it is difficult to balance the self-locking reliability under vibration environment, resulting in a contradiction between structural design and functional requirements. Utility Model Content

[0007] The purpose of this utility model is to provide an electric roller shutter motor with a braking structure. By integrating a braking structure consisting of an electromagnetic coil, an armature, and brake pads into the motor, the armature and brake pads are engaged and disengaged, thereby stabilizing the frictional resistance and limiting the rotation of the worm gear. This solves the problem that the roller shutter cover is easily shaken open on vibrating roads due to insufficient self-locking force of the motor with the output shaft perpendicular to the worm gear.

[0055] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0056] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0057] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: In some embodiments, it includes: a motor body 1; a roller shutter drive gear 11, which is fixedly installed at the output end of the motor body 1 and is used for the opening and closing transmission of the roller shutter cover; an electric rear end extension 12, which is provided at the tail end of the motor body 1; a first brake disc 13, which is screwed and fixedly mounted at the output end of the first brake disc 13; and a second brake disc 35, the deceleration surface of the second brake disc 35 cooperating with the first brake disc 13.

[0058] In this embodiment, the motor body 1 serves as the core driving component, and the roller shutter transmission gear 11 fixed at its output end undertakes the transmission function of opening and closing the roller shutter cover; the electric rear extension part 12 extended at the tail of the motor body 1 provides a structural extension basis for the installation of the first brake disc 13, and the deceleration surface of the first brake disc 13 and the second brake disc 35 cooperate to form a key contact structure for achieving the braking effect. The switching of the braking state is completed by the contact and separation of the two.

[0059] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: motor body 1; motor mounting part 111, which is fixed to the tail of motor body 1; connecting part 2, which is fixedly connected to the motor mounting part 111 by screws; mounting base 3, which is fixedly installed on the outer surface of connecting part 2; sealing strip 21, which is sealed and embedded in the mounting groove between connecting part 2 and mounting base 3.

[0060] In this embodiment, the motor mounting part 111 provides a fixed base point for the connection between the connecting part 2 and the motor body 1. The two are fixedly connected by screws to ensure structural stability. The mounting base 3 is fixed to the outer surface of the connecting part 2, forming the mounting carrier for the subsequent brake components. The sealing strip 21 is embedded in the mounting groove between the connecting part 2 and the mounting base 3, which can effectively prevent external dust and moisture from entering the internal gap and improve the overall sealing performance.

[0061] In some embodiments, as shown in the appendixFigure 1 To be continued Figure 5 As shown: Mounting base 3; Brake housing 31, which is fixedly mounted on the outer surface of mounting base 3.

[0062] In this embodiment, the brake housing 31 is fixed to the outer surface of the mounting base 3, serving as a protective housing for the brake system. This provides installation space for internal components such as the spring 33 and the electromagnetic coil 5, and also provides physical protection for these components, reducing interference from the external environment on the brake assembly.

[0063] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: brake housing 31; sealing ring 22, the sealing ring 22 seals the mounting groove between the brake housing 31 and the connecting part 2.

[0064] In this embodiment, the sealing ring 22 is sealed and embedded in the mounting groove between the brake housing 31 and the connecting part 2, which further enhances the sealing performance of the connection position between the brake housing 31 and the connecting part 2. It works in conjunction with the sealing strip 21 to form a multi-layer sealing structure, thereby improving the dustproof and waterproof capabilities of the device.

[0065] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: mounting base 3; mounting plate 32, which is fixedly installed inside the brake housing 31; spring 33, one end of which is fixedly installed inside the mounting plate 32.

[0066] In this embodiment, the mounting plate 32 is fixed inside the brake housing 31, providing a stable mounting support point for the spring 33; one end of the spring 33 is fixed to the mounting plate 32, and its elastic potential energy can be converted into the power to push the second brake disc 35, which is the core elastic component for realizing the braking state reset.

[0067] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: spring 33; connecting part 34, one end of the connecting part 34 is fixedly installed on one end of the spring 33; second brake disc 35, the outer surface of the second brake disc 35 is fixedly installed on the mounting part of the connecting part 34.

[0068] In this embodiment, the connecting component 34 serves as the connecting medium between the spring 33 and the second brake disc 35, stably transmitting the elastic force of the spring 33 to the second brake disc 35, ensuring that the force of the spring can effectively drive the movement of the second brake disc 35, and ensuring the precise switching of the brake disc engagement relationship.

[0069] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5As shown: second brake disc 35; mounting ring 4, the outer surface of the mounting ring 4 is fixedly mounted to the outer surface of the second brake disc 35 by screws; armature 41, the outer surface of the armature 41 is fixedly mounted to the outer surface of the mounting ring 4 by screws; the outer wall of the armature 41 and the inside of the brake housing 31 slide against each other for sliding limit.

[0070] In this embodiment, the mounting ring 4 rigidly connects the armature 41 to the second brake disc 35 with screws, so that the three form a linked whole; the outer wall of the armature 41 slides against the inside of the brake housing 31, which not only restricts the movement direction of the armature 41 (sliding only along the axial direction), but also prevents it from deviating or shaking during movement, thus ensuring the coaxiality of the second brake disc 35 when it is engaged with the first brake disc 13.

[0071] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: brake housing 31; electromagnetic coil 5, which is disposed inside the brake housing 31; limit block 51, the mounting part of each limit block 51 is fixedly installed on the outer wall of the electromagnetic coil 5.

[0072] In this embodiment, the electromagnetic coil 5 is disposed inside the brake housing 31 and is the core component for generating electromagnetic force; the limiting block 51 is fixed to the outer wall of the electromagnetic coil 5, which can initially position the electromagnetic coil 5 in the housing, prevent it from shifting when not in operation, and ensure the accuracy of the direction of electromagnetic force.

[0073] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: Each limiting block 51 is fixedly installed on the inner wall of the brake housing 31.

[0074] In this embodiment, the limiting block 51 is simultaneously fixed to the inner wall of the brake housing 31. Through double fixing (connected to both the outer wall of the electromagnetic coil 5 and the inner wall of the brake housing 31), the electromagnetic coil 5 is firmly locked in the preset position, preventing it from loosening when it generates a magnetic field or is subjected to force, thus ensuring the stability and consistency of the electromagnetic attraction.

[0075] In some embodiments, as shown in the appendix Figure 1 To be continued Figure 5 As shown: The electromagnetic coil 5 is energized and de-energized to control the engagement relationship between the first brake disc 13 and the second brake disc 35.

[0076] In this embodiment, the on / off state of the electromagnetic coil 5 directly determines the cooperation relationship between the first brake disc 13 and the second brake disc 35: when energized, electromagnetic force is generated to drive the brake to be released, and when de-energized, the braking is achieved by spring force. This control logic is simple and efficient and is the core control mechanism of the entire braking system.

[0077] Working principle: When the electromagnetic coil 5 is de-energized, the spring 33 releases its elastic potential energy, which pushes the second brake disc 35 towards the first brake disc 13 through the connecting component 34, so that the deceleration surfaces of the two are tightly fitted, and braking is achieved by friction, keeping the roller shutter cover stationary; when the electromagnetic coil 5 is energized, the electromagnetic force it generates attracts the armature 41, and the armature 41 drives the second brake disc 35 to move in the opposite direction against the elastic force of the spring 33 through the mounting ring seat 4, so that the first and second brake discs are separated, the braking is released, and the motor body 1 drives the roller shutter cover to open and close through the roller shutter transmission gear 11. During this process, the sliding cooperation between the armature 41 and the brake housing 31 ensures smooth movement, the sealing strip 21 and the sealing ring 22 protect the internal components from external environmental corrosion, and the limit block 51 fixes the position of the electromagnetic coil 5 to ensure the stability of the electromagnetic force, ultimately achieving precise start and stop control of the roller shutter cover.
