[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] like Figs. 1 to 5 As shown: An integrated brushless motor-driven linear actuator, comprising:

[0027] Brushless motor 1, one end of brushless motor 1 includes an output shaft;

[0028] Transmission mechanism 2 is located at one end of the output shaft of brushless motor 1 and is connected to the output shaft for transmission.

[0029] Push rod 3 is connected to the end of transmission mechanism 2 away from brushless motor 1. Brushless motor 1 drives push rod 3 to rotate through transmission mechanism 2.

[0030] Compared to traditional brushed motors, brushless motor 1 has higher operating efficiency because it lacks easily worn parts such as brushes and commutators, thus reducing energy loss. At the same power output, brushless motor 1 can provide higher output torque and more stable operation. Brushless motor 1 can intelligently adjust according to load changes, ensuring efficient operation under various working conditions and avoiding efficiency reduction due to overload or load imbalance.

[0031] By employing a brushless motor 1 and a high-efficiency transmission mechanism 2, the operational stability of the entire push rod 3 system is enhanced, reducing wear and tear on mechanical components and the risk of failure, thus lowering the need for maintenance and parts replacement. Furthermore, the brushless motor 1 has excellent heat dissipation performance, maintaining a low temperature even under high loads, preventing component damage and efficiency degradation caused by overheating, thereby improving the overall system durability.

[0032] In this embodiment, the brushless motor 1 has a circuit board 12 at the end away from the output shaft. The circuit board 12 includes a board body 121 and a control line 122.

[0033] The circuit board 12 is arranged at the end of the brushless motor 1 away from the output shaft, which makes the layout of the circuit board 12 and the control line 122 more compact, and avoids interference between the circuit board 12 and the transmission mechanism 2. The circuit board 12 usually contains control circuits and sensor interfaces, etc. Through this design, the motor control system can be more conveniently integrated into the overall structure, improving the integration and reliability of the system.

[0034] As a preferred embodiment of the above, the brushless motor 1 and the transmission mechanism 2 have the same outer contour and equal area.

[0035] This design makes the brushless motor 1 and the transmission mechanism 2 more matched in size and shape, effectively saving space and ensuring the compactness of the entire system. Through the same outer contour and area configuration, space can be more efficiently utilized, and installation is more convenient, reducing the complexity of installation and maintenance.

[0036] Among them, the brushless motor 1 and the transmission mechanism 2 are fixedly connected by fasteners along the length direction of the push rod 3.

[0037] By fixedly connecting the brushless motor 1 and the transmission mechanism 2 along the length direction of the push rod 3 through fasteners, the stability of the overall structure can be improved, avoiding loosening or deformation of the connection due to vibration or external force during use. In this way, the system can maintain higher mechanical precision during operation.

[0038] In this embodiment, the brushless motor 1 is provided with a plurality of slots 13 at the end away from the transmission mechanism 2, the housings of the brushless motor 1 and the transmission mechanism 2 are provided with threaded holes 14 corresponding to the slots 13, and the fasteners are bolts.

[0039] Among them, the slots 13 are four and are respectively arranged at the four corners of the end of the brushless motor 1 away from the transmission mechanism 2.

[0040] By providing slots 13 on the housings of the brushless motor 1 and the transmission mechanism 2 and connecting them through bolts, an efficient fixing method is provided. The bolts are screwed into the threaded holes 14 from the slots 13, which not only simplifies the assembly process, but also facilitates disassembly and maintenance when needed. The four slots 13 are respectively arranged at the four corners of the end of the brushless motor 1 away from the transmission mechanism 2, which further improves the stability of the fixing and avoids deformation or loosening of the components due to uneven forces.

[0041] As a preferred embodiment of the above, the transmission mechanism 2 is a planetary reducer.

[0042] The planetary reducer as the transmission mechanism 2 can provide high transmission efficiency and high torque output. Due to the uniform gear configuration and strong bearing capacity of the planetary reducer, vibration and noise during transmission can be effectively reduced, more stable power output is provided, and accurate control of the push rod 3 is realized.

[0043] The push rod 3 is provided with a hexagonal structure 31 at one end connected with the transmission mechanism 2, and the transmission mechanism 2 is provided with a hexagonal hollow cavity 21 at one end close to the push rod 3, the hexagonal structure 31 is inserted and matched with the hexagonal hollow cavity 21, and the push rod 3 is driven.

[0044] The hexagonal structure 31 and the hollow cavity are inserted and matched with each other, so that the connection between the push rod 3 and the transmission mechanism 2 is more firm, and the problems of sliding or loosening caused by the traditional circular connection mode are avoided. The hexagonal structure can provide better contact area and stronger locking force, improve the accuracy and stability of transmission, and help to maintain the performance consistency of the push rod 3 in long-term use.

[0045] The embodiment also includes a lifting device, which comprises a vertically arranged cavity, and the cavity is provided with the integrated brushless motor 1 power push rod 3.

[0046] By adopting the brushless motor 1 and the high-efficiency transmission mechanism 2, the running stability of the entire push rod 3 system is enhanced, the wear and failure risk of mechanical parts are reduced, and the demand for maintenance and replacement of parts is reduced. The heat dissipation performance of the brushless motor 1 is good, which can still maintain a low temperature when working under high load, avoiding damage to parts and efficiency reduction caused by overheating, thereby improving the durability of the entire system.
