A drive shaft is installed at the center of the top of the housing, and a drive gear is connected to the bottom of the drive shaft. Four commutation components are installed in a ring around the drive gear inside the housing. The advantages are: by installing four commutation components, each consisting of an electric actuator, connecting bearing, sliding sleeve, protruding edge, driven gear, and driven shaft, in a ring around the drive gear inside the housing, and by installing a guide assembly consisting of a guide slide and a guide groove between the sliding sleeve of each commutation component and the side wall of the housing, the motor commutator can be used to ensure the meshing of the driven gear and drive gear in the corresponding direction by controlling the extension and retraction of the electric actuators in each commutation component.

Description

Technical Field

[0001] This utility model relates to the field of motor power commutation, specifically to a motor commutator. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. The basic working principle of an electric motor is that the interaction of an electric current with a magnetic field generates torque, which drives mechanical parts to rotate. Electric motors are widely used in various devices, such as household appliances, industrial machinery, power tools, and electric vehicles. In practical applications, a commutator is needed to facilitate the transmission of power from the motor.

[0003] Existing motor commutators for power reversing mainly consist of a housing, a power input shaft mounted on the housing, a speed-changing assembly with a fixed structure mounted inside the housing, and a power output shaft mounted on the power output end of the speed-changing assembly. Although this type of motor commutator can input the motor's power into the housing via the power input shaft and output the motor's power to external equipment in a specific direction under the action of the speed-changing mechanism inside the housing, the power reversing method of the speed-changing mechanism inside the existing motor commutator is relatively simple. As a result, the motor commutator cannot meet the need for convenient reversing transmission of motor power in different directions in actual use, thus making the motor commutator less flexible in use. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a motor commutator that can conveniently transmit motor power in multiple directions according to actual use needs, based on the current state of the technology.

[0005] This utility model is achieved through the following technical solution: This utility model proposes a motor commutator, including a housing, a drive shaft installed at the top center of the housing, a drive gear connected to the bottom end of the drive shaft, and four commutation components installed in a ring around the drive gear inside the housing, with an included angle of 90° between every two adjacent commutation components. Each commutation component includes an electric push rod, a connecting bearing, a sliding sleeve, a protruding edge, a driven gear, and a driven shaft. The sliding sleeve is installed in the middle of the side wall of the housing, the connecting bearing is located inside the sliding sleeve, the driven shaft is installed inside the connecting bearing, the protruding edge is formed at one end of the sliding sleeve inside the housing, the electric push rod is installed between the protruding edge and the inner wall of the housing, and the driven gear is installed at one end of the driven shaft inside the housing. A guide component is installed between the sliding sleeve and the inner wall of the housing in each commutation component. The guide component includes a guide slide and a guide groove. Two ear plates with self-mounting holes are also reserved on both sides of the bottom end of the housing.

[0006] Furthermore, each of the guide components has two guide slides, and the two guide slides are symmetrically installed in the middle of the outer side walls of the sleeve.

[0007] Furthermore, the guide groove is formed on the side wall of the housing and mates with the guide slide, and the guide slide and the guide groove are slidably engaged.

[0008] Furthermore, the outer ring of the connecting bearing is inserted into the sliding sleeve, and the inner ring of the connecting bearing is inserted into the driven shaft.

[0009] Furthermore, the driven shaft passes through the slide and is welded to the driven gear, and the diameter of the driven gear is larger than the diameter of the driving gear.

[0010] Furthermore, both the driving gear and the driven gear are bevel gears, and the driving shaft passes through the housing and is rotatably connected to the housing.

[0011] Furthermore, the sliding sleeve penetrates the side wall of the housing, and the sliding sleeve is welded to the convex edge, which has an annular structure.

[0012] Furthermore, the telescopic part of the electric actuator is connected to the convex bolt, and the fixed part of the electric actuator is connected to the inner wall of the box by bolts.

[0013] Compared with the prior art, this utility model has the following advantages:

[0014] This invention features four commutation assemblies arranged in a ring below the drive gear within the housing. These assemblies consist of electric push rods, connecting bearings, sliding sleeves, protruding edges, driven gears, and driven shafts. A guide assembly, consisting of guide slides and guide grooves, is installed between the sliding sleeve of each commutation assembly and the side wall of the housing. This allows the motor commutator to control the extension and retraction of the electric push rods in each commutation assembly during use, ensuring meshing between the driven gear and drive gear in the corresponding direction. This enables the on-demand transmission of motor power in four mutually perpendicular directions within the horizontal plane, effectively improving the flexibility of the motor commutator.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0023] like Figures 1-3 As shown, a motor commutator in this embodiment includes a housing 2. A drive shaft 1 is installed at the top center of the housing 2, and a drive gear 4 is connected to the bottom end of the drive shaft 1. Four commutation components 5 are installed in a ring around the drive gear 4 inside the housing 2, with an included angle of 90° between any two adjacent commutation components 5. Each commutation component 5 includes an electric actuator 501, a connecting bearing 502, a sliding sleeve 503, a protruding edge 504, a driven gear 505, and a driven shaft 506. The sliding sleeve 503 is installed in the middle of the side wall of the housing 2, and the connecting bearing 502 is located in the middle of the sliding sleeve 505. Inside the sleeve 503, the driven shaft 506 is installed inside the connecting bearing 502. The protruding edge 504 is formed on one end of the sleeve 503 located inside the housing 2. The electric push rod 501 is installed between the protruding edge 504 and the inner wall of the housing 2. The driven gear 505 is installed on one end of the driven shaft 506 located inside the housing 2. A guide assembly 6 is installed between the sleeve 503 and the inner wall of the housing 2 in each reversing assembly 5. The guide assembly 6 includes a guide slide 601 and a guide groove 602. Two ear plates 3 with their own mounting holes are also reserved on both sides of the bottom end of the housing 2.

[0024] This utility model provides a motor commutator that can conveniently transmit motor power in multiple directions according to actual usage needs. It solves the problem that while existing motor commutators can input motor power into the housing 2 via the power input shaft and output the power to external devices in a specific direction under the action of the speed-changing mechanism within the housing 2, the existing commutator's speed-changing mechanism has a relatively simple power commutation method. This results in the commutator being unable to meet the need for convenient power transmission in different directions during actual use, thus leading to poor flexibility in its use. This utility model addresses this issue. For example, the overall approach to solving the above problems is as follows: When reversing the power of the motor, the electric push rod 501 on the corresponding reversing assembly 5 is first activated by the external power supply and control components. After the electric push rod 501 is activated, the driven gear 505 in the reversing assembly 5 moves closer to the driving gear 4. After the driven gear 505 meshes with the driving gear 4, the motor power is conveniently transmitted to the corresponding direction, ensuring that the motor power can be reversing and adjusted as needed. When moving the sliding sleeve 503 during the reversing process, the guide slide 601 and the guide slide groove 602 can ensure the stable movement of the sliding sleeve 503 and achieve efficient adjustment of the position of the sliding sleeve 503.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, each guide assembly 6 has two guide slides 601, and the two guide slides 601 are symmetrically installed in the middle of the outer two side walls of the slide sleeve 503.

[0026] In one implementation, the guide slide 601 and the slide sleeve 503 are an integral structure. With the sliding cooperation between the guide slide 601 and the guide groove 602, the sliding adjustment of the slide sleeve 503 relative to the side wall of the housing 2 is more stable and convenient.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the guide groove 602 is formed on the side wall of the housing 2 and is in contact with the guide slide 601. The guide slide 601 and the guide groove 602 are in sliding contact.

[0028] As one implementation, the guide slide 601 and the guide slide groove 602 are slidably engaged, which not only ensures the stable sliding of the slide sleeve 503, but also prevents the slide sleeve 503 from rotating relative to the side wall of the housing 2 during the sliding process. Furthermore, the guide slide 601 and the guide slide groove 602 are always in contact during the sliding adjustment process of the slide sleeve 503.

[0029] like Figure 2 , Figure 3 and Figure 5As shown, the outer ring of the connecting bearing 502 is inserted into the sliding sleeve 503, and the inner ring of the connecting bearing 502 is inserted into the driven shaft 506.

[0030] As one implementation method, the plug-in fixing method makes the connecting bearing 502 more securely fixed in the sliding sleeve 503, and the plug-in connection between the inner ring of the connecting bearing 502 and the driven shaft 506 can ensure that the driven shaft 506 can be easily rotated and adjusted with the inner ring of the connecting bearing 502.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, the driven shaft 506 passes through the slide and is welded to the driven gear 505. The diameter of the driven gear 505 is larger than the diameter of the driving gear 4.

[0032] In one implementation, the driven shaft 506 is welded to the driven gear 505, which can ensure that the driven shaft 506 rotates synchronously with the driven gear 505.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, both the driving gear 4 and the driven gear 505 are bevel gears, and the driving shaft 1 passes through the housing 2 and is rotatably connected to the housing 2.

[0034] As one implementation method, the rotating connection installation method makes it more convenient for the drive shaft 1 to rotate relative to the housing 2.

[0035] like Figures 1-3 As shown, the sliding sleeve 503 penetrates the side wall of the housing 2, and the sliding sleeve 503 is welded to the protruding edge 504, which has a ring structure.

[0036] As one implementation method, the protruding edge 504 is mainly used to facilitate the connection between the electric actuator 501 and the sliding sleeve 503.

[0037] like Figure 2 and Figure 3 As shown, the telescopic part of the electric actuator 501 is bolted to the protruding edge 504, and the fixed part of the electric actuator 501 is bolted to the inner wall of the housing 2.

[0038] In one implementation, the electric actuator 501 is installed between the protruding edge 504 and the inner wall of the housing 2, which allows the sliding sleeve 503 to slide easily in the horizontal direction under the action of the electric actuator 501, so as to realize the on-demand meshing of the corresponding driven gear 505 and the driving gear 4.

[0039] The specific implementation process of this embodiment is as follows: When in use, first install the external motor on the top of the housing 2 and connect the external motor to the drive shaft 1. Then connect the commutator to the external power supply and control components. Then, simply start the electric push rod 501 on the corresponding commutation component 5. After the electric push rod 501 is started, the driven gear 505 in the commutation component 5 will move closer to the drive gear 4. After the driven gear 505 and the drive gear 4 mesh and contact, the motor power is conveniently transmitted to the corresponding direction, ensuring the on-demand commutation adjustment of the motor power. Since the motor commutator can be used to ensure that the driven gear 505 in the corresponding direction meshes with the drive gear 4 by controlling the extension and retraction of the electric push rod 501 in each commutation component 5, the motor power can be transmitted on demand in four mutually perpendicular directions in the horizontal plane, thereby effectively improving the flexibility of the motor commutator.
