Description

Technical Field

[0001] This utility model relates to the field of electro-disc brake technology, specifically a constant current multi-voltage electro-disc brake. Background Technology

[0002] An electro-disc brake is a mechanical device that uses electromagnetic force to achieve braking. Its core principle is that an electromagnet, when energized, generates a magnetic field that attracts the iron parts of the brake disc, causing the disc to come into close contact with the friction pads. This generates frictional torque to stop the rotation of the components. During operation, the electro-disc brake directly generates braking force through the energization of the electromagnet, eliminating the need for hydraulic or pneumatic transmission. This results in extremely low action delay, and the coefficient of friction between the brake disc and the friction pads is minimally affected by temperature. Furthermore, the disc structure has no self-amplifying effect, ensuring stable braking torque output. When using an electro-disc brake, a positioning component is typically used to assist in its operation. Since the friction plates on the surface of the positioning component are usually fixed with multiple sets of bolts, if the friction plates are damaged and need immediate replacement, it is necessary to first find the tools to tighten the bolts, which is time-consuming and affects usability.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent application number 202222378763.2, application date 2022-09-07) provides an electro-disc brake with a built-in positioning component. The electro-disc brake body and the positioning plate have through holes on their surface and grooves at one end. A rubber sleeve is placed in the groove, and a friction plate is snapped onto one end of the positioning plate. A snap is also provided on the side of the friction plate. In use, the electro-disc brake with a built-in positioning component first presses down the pressure rod, then inserts the friction plate into the groove. The rubber sleeve in the groove can better fit the friction plate and enhance stability. After the snap at one end of the friction plate is inserted into the through hole, the pressure rod is released, and the pressure rod is reset by the spring force, so that the pressure rod limits the snap. When the friction plate is damaged, a new friction plate can be replaced simply by pressing down the pressure rod.

[0004] The voltage range available for electro-disc brakes, both domestically and internationally, is relatively narrow, typically offering only a limited selection of 96V, 103V, 170V, 180V, and 205V. This cannot fully meet the needs of most countries worldwide. Furthermore, the excessive number of voltage options makes it difficult to manufacture standardized electro-disc brakes, resulting in longer production cycles for non-standard products and impacting the overall production schedule. During use, the inability of the device to operate under different voltages reduces its versatility across various power environments. Additionally, the inability to achieve effective air convection within the lifting mechanism drum prevents the timely dissipation of heat generated during braking, leading to accelerated thermal fatigue of the drum material and deterioration of lubricating oil performance. Utility Model Content

[0005] The purpose of this invention is to provide a constant current multi-voltage electric disc brake to solve the problems mentioned in the background art, which prevent the device from working under different voltages, thus reducing the device's versatility under different power environments. At the same time, the air inside the lifting mechanism drum cannot form effective convection, and the heat generated during braking cannot be dissipated in time, leading to increased thermal fatigue of the drum material and deterioration of lubricating oil performance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a constant current multi-voltage electro-disc brake, comprising a base, a support frame fixedly connected to the upper surface of the base, the support frame being symmetrically distributed about the center of the base, and ventilation holes being provided inside both the support frame and the base; a braking assembly being slidably connected to the upper surface of the base; the braking assembly being slidably disposed inside the support frame, and a friction assembly being fixedly connected to the lower left end of the braking assembly, and the ventilation holes being provided inside the braking assembly; a fixing block being fixedly connected to the lower end of the braking assembly; a sliding groove being provided inside the fixing block via a locking assembly; a limiting rod being fixedly connected to the upper surface of the base, and the limiting rod slidably passing through the limiting block, and the surface of the limiting block being inclined at the end near the base.

[0007] Preferably, one end of the connecting spring is fixedly connected to the surface of the sliding groove, and the engaging structure includes a telescopic block fixedly connected to the other end of the connecting spring.

[0008] Preferably, the lower surface of the telescopic block is inclined near the base, and a positioning groove is provided inside the base, with the lower end of the braking component nested and connected inside the positioning groove.

[0009] Preferably, a connecting block is fixedly connected to the upper surface of the base, and the telescopic block is slidably connected to the surface of the connecting block.

[0010] Preferably, a baffle is fixedly connected to the upper surface of the base, and a sliding block is slidably connected inside the baffle, and the surface of the sliding block is inclined at the end near the braking assembly.

[0011] Preferably, a fixing plate is fixedly connected to the surface of the sliding block, and one end of a fixing spring is fixedly connected to the surface of the fixing plate, while the other end of the fixing spring is fixedly connected to the baffle. At the same time, a push plate is fixedly connected to the end of the sliding block surface near the positioning groove.

[0012] Preferably, a pull rod is fixedly connected to the upper surface of the limiting block, and one end of a buffer spring is fixedly connected to the lower surface of the limiting block, and the other end of the buffer spring is fixedly connected to the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This constant current multi-voltage electro-disc brake adopts a novel structural design, the specific details of which are as follows: (1) The constant current multi-voltage electric disk brake, through the electric disk brake, enables the device to be applicable under different voltages. Even if the lifting height increases, the left and right limits of the electric hoist will be significantly reduced compared to before, improving the product utilization efficiency. At the same time, by adding ventilation holes, the drum of the entire lifting mechanism is ventilated, extending the overall service life of the lifting mechanism.

[0014] Furthermore, improved ventilation helps maintain the good performance of the lubricating oil, ensures smooth operation between components, reduces vibration and noise, improves the stability and reliability of the lifting mechanism, and ensures that the equipment maintains a good working condition during long-term operation.

[0015] (2) The constant current multi-voltage electric disk brake can disassemble the base by setting the fixed block and the telescopic block, which not only improves the maintenance efficiency and maintenance quality of the staff, but also reduces the production interruption caused by equipment maintenance, indirectly reducing the production cost of the enterprise and improving the production efficiency.

[0016] Furthermore, by installing the base, it is possible to better adapt to different installation site conditions, thereby improving the accuracy and efficiency of installation.

[0017] (3) The constant current multi-voltage electric disc brake improves the stability of the device during operation through the set support frame and baffle, which can prevent the deformation or damage of the components caused by uneven force, ensure the structural integrity and stability of the brake, extend its service life, and thus ensure the consistency and reliability of the braking effect.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: By incorporating the braking component 4, vent 3, and friction component 5, the device can operate under different voltages, while simultaneously improving its working efficiency. Figures 1-2 As shown: It includes a base 1, a support frame 2 is fixedly connected to the upper surface of the base 1, and the support frame 2 is symmetrically distributed about the center of the base 1. Both the support frame 2 and the base 1 have ventilation holes 3. At the same time, a braking component 4 is slidably connected to the upper surface of the base 1. The braking component 4 is slidably disposed inside the support frame 2. A friction component 5 is fixedly connected to the lower left end of the braking component 4. The braking component 4 has ventilation holes 3 inside. At the same time, a fixing block 6 is fixedly connected to the lower end of the braking component 4. The fixing block 6 has a sliding groove 7 provided inside through a locking component. A limit rod 17 is fixedly connected to the upper surface of the base 1. The limit rod 17 slidably passes through and connects to a limit block 18. The surface of the limit block 18 is inclined at the end near the base 1.

[0028] The staff installed the device in the designated location and started it. When the device was connected to a power source with different voltages (such as...), Figure 1 and Figure 2 As shown), the internal components of the braking assembly 4 can automatically identify and adjust, ensuring that the device can work normally under different voltages. Meanwhile, the vent 3 helps dissipate heat generated by the device under different voltages, maintaining the normal operating temperature of the internal components and ensuring its stability under different voltage conditions. When braking is required, external mechanical force is transmitted to the friction assembly 5 through the braking assembly 4. The friction assembly 5 uses friction to generate a braking effect (e.g., ...). Figure 1 As shown, when the staff disassembles the brake assembly 4 and the base 1, they press the lever 19 to separate the brake assembly 4 and the base 1, which improves the staff's maintenance efficiency and maintenance quality.

[0029] In Example 2, unlike Example 1, the inclusion of the telescopic block 9, positioning groove 10, and connecting block 11 allows the device to better adapt to different installation site conditions, improving installation accuracy and efficiency. Figures 4-5 As shown: one end of the connecting spring 8 is fixedly connected to the surface of the sliding groove 7, and the engaging structure includes a telescopic block 9 fixedly connected to the other end of the connecting spring 8. The lower surface of the telescopic block 9 is inclined near the base 1, and a positioning groove 10 is provided inside the base 1. The lower end of the braking component 4 is nested and docked inside the positioning groove 10. A connecting block 11 is fixedly connected to the upper surface of the base 1, and the telescopic block 9 is slidably connected to the surface of the connecting block 11.

[0030] When the operator connects the brake assembly 4 and the base 1, the brake assembly 4 is pushed to connect with the positioning groove 10 inside the base 1 (e.g., Figure 3 As shown), and when the telescopic block 9 on the surface of the fixed block 6 contacts the connecting block 11, the connecting block 11 pushes the telescopic block 9 to slide towards the surface of the sliding groove 7, while simultaneously causing the connecting spring 8 on the surface of the telescopic block 9 to retract towards the inner wall of the fixed block 6 (as shown). Figure 4 and Figure 5 When the braking assembly 4 is fully engaged with the positioning groove 10, the connecting spring 8 pushes the telescopic block 9, causing the telescopic block 9 to slide on the inner wall of the connecting block 11 and engage with the inner wall of the connecting block 11. This achieves good adaptation of the device to the site conditions and greatly expands the applicability of the device.

[0031] In Example 3, unlike Example 2, the base 1 can be disassembled using the fixed spring 16, buffer spring 20, and pull rod 19, improving the efficiency and quality of maintenance for the operator. Figures 6-7 As shown: A baffle 12 is fixedly connected to the upper surface of the base 1, and a sliding block 13 is slidably connected inside the baffle 12. The surface of the sliding block 13 is inclined at the end near the braking assembly 4. A fixing plate 15 is fixedly connected to the surface of the sliding block 13, and one end of a fixing spring 16 is fixedly connected to the surface of the fixing plate 15. The other end of the fixing spring 16 is fixedly connected to the baffle 12. At the same time, a push plate 14 is fixedly connected to the end of the sliding block 13 near the positioning groove 10. A pull rod 19 is fixedly connected to the upper surface of the limiting block 18, and one end of a buffer spring 20 is fixedly connected to the lower surface of the limiting block 18. The other end of the buffer spring 20 is fixedly connected to the base 1.

[0032] When the staff disassembles the base 1, they press the lever 19 at the upper end of the limit block 18 (as shown in the image). Figure 7 As shown), the pull rod 19 drives the limiting block 18 to slide on the surface of the limiting rod 17, and causes the buffer spring 20 on the surface of the limiting block 18 to retract towards the surface of the base 1. At the same time, the limiting block 18 squeezes the sliding block 13, pushing the sliding block 13 to slide inside the baffle 12, and causes the fixing spring 16 on the surface of the fixing plate 15 to retract towards the surface of the baffle 12 (as shown). Figure 6 As shown in the figure, the push plate 14 at the end of the sliding block 13 slides on the inner wall of the connecting block 11, thereby pushing the telescopic block 9 to slide towards the inner wall of the fixed block 6, thereby separating the braking assembly 4 and the base 1. This can reduce production interruptions caused by equipment maintenance, indirectly reduce the company's production costs, and improve production efficiency.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
