Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to an integrated drive mechanism. Background Technology

[0002] Motors are widely used in automated equipment, smart homes, robots, vehicle electric drive devices, and various electric actuators due to their compact structure and ability to flexibly change the direction of power output. The normal operation of such motors requires a dedicated control box (or driver), which integrates motor drive circuitry, control units (such as MCUs), signal processing, and communication interfaces to receive external commands and precisely control the motor's start, stop, speed, and direction.

[0003] Currently, the mainstream solution on the market adopts a split structure. This means the motor and its control box are two independent physical entities, manufactured separately, requiring secondary assembly during on-site installation. This traditional architecture has the following inherent drawbacks:

[0004] First, the increased number of components increases costs. Split-type installation requires the use of external, dedicated wiring harnesses and essential connectors at both ends of the harness to achieve the electrical connection between the control box and the motor. The wiring harness itself and the connectors are additional parts, increasing both component and manufacturing costs.

[0005] Secondly, the installation process is cumbersome and inefficient. Installers need to perform multiple operations: first, they must fix the motor and control box to the equipment frame or housing; then, they must find the path to lay the wiring harness; finally, they must align and plug in one end of the wiring harness with the control box interface, and then align and plug in the other end with the motor interface. The entire process involves many steps and is time-consuming, reducing production assembly efficiency. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an integrated drive mechanism to solve the technical problems of a large number of parts and complicated installation procedures in the prior art.

[0007] To achieve the above objectives, this utility model provides an integrated drive mechanism, comprising: a control structure, the control structure including a control housing, a first buckle disposed at one end of the control housing, and a PCB board disposed inside the control housing; a drive structure, the drive structure including a drive housing and a motor disposed inside the drive housing; the PCB board being electrically connected to the motor; a first slot corresponding to the first buckle being provided at one end of the drive housing, one end of the control housing being inserted into one end of the drive housing and being engaged in the first slot by the first buckle, thereby connecting the control housing and the drive housing together; a sealing ring being provided at the connection between the control housing and the drive housing, one end of the sealing ring abutting against the end face of one end of the control housing, and the other end abutting against the motor.

[0008] In a preferred embodiment, the control housing includes an upper housing and a lower housing connected to the upper housing, with the first latch respectively disposed at one end of the upper housing and the lower housing.

[0009] As a preferred embodiment, one end of the drive housing is further provided with a guide groove, and one end of the lower housing is provided with a guide protrusion corresponding to the guide groove, the guide protrusion being engaged in the guide groove.

The connecting seat is provided with a second slot corresponding to the second buckle, and the second buckle is engaged in the second slot to connect the upper housing and the lower housing together.

[0011] As a preferred embodiment, one end of the drive housing is further provided with a partition groove, which is located on both sides of the first slot. During the process of the first buckle engaging into the first slot, the partition groove causes the area where the first slot is located to form an elastic cantilever. The elastic cantilever is elastically deformed outward under the pressure of the first buckle, and the elastic cantilever returns to its original position after the first buckle engages with the first slot.

[0012] As a preferred embodiment, the control housing further includes water guide channels, which are respectively disposed at one end of the upper housing and the lower housing, and the water guide channels on the upper housing and the lower housing are interconnected. A water outlet communicating with the water guide channels is provided at the bottom of one end of the lower housing.

[0013] As a preferred embodiment, the lower edge of the inner sidewall of the upper housing is provided with an outward protrusion, the upper edge of the inner sidewall of the lower housing is provided with an inward protrusion and a waterproof platform extending outward along the inward protrusion, and the outward protrusion engages with the inward protrusion.

[0014] In a preferred embodiment, the control structure further includes a wire harness connector connected to the PCB board; the wire harness connector is provided with a water-guiding step in its circumference, and a water-guiding cavity is provided at the bottom of the other end of the lower housing, with a water-guiding through hole provided in the water-guiding cavity. Water that intrudes into the joint between the upper housing, the lower housing, and the wire harness connector flows along the water-guiding step under the action of gravity toward the water-guiding through hole provided in the water-guiding cavity, and then flows out from the water-guiding through hole.

[0015] As a preferred embodiment, the PCB board is provided with connection terminals, which are electrically connected to the power supply terminal of the motor.

[0016] As a preferred embodiment, the drive structure further includes a mounting base disposed at the other end of the drive housing.

[0017] As described above, the integrated drive mechanism of this utility model has the following beneficial effects:

[0018] One end of the control housing is inserted into one end of the drive housing and is secured in the first slot by the first snap-fit, thus achieving a tight connection between the control housing and the drive housing. The PCB board is electrically connected to the motor, thereby integrating the control structure and the drive structure into one unit. This reduces the need for external dedicated wiring harnesses and connectors at both ends, lowering component procurement and manufacturing costs. Furthermore, the installation process is simplified by the cooperation of the first snap-fit ​​and the first slot, improving assembly efficiency. In addition, a sealing ring is provided at the connection between the control housing and the drive housing. One end of the sealing ring abuts against the end face of one end of the control housing, and the other end abuts against the motor. This not only fills the assembly gap between the control housing and the drive housing, making the connection between them tighter, but also prevents moisture intrusion, improving waterproof performance.

[0067] like Figure 1-7 As shown, this utility model provides an integrated drive mechanism, including:

[0068] Control structure 1, the control structure 1 includes a control housing 11, a first buckle 12 disposed at one end of the control housing 11, and a PCB board 13 disposed inside the control housing 11;

[0069] The drive structure 2 includes a drive housing 21 and a motor 22 disposed inside the drive housing 21; the PCB board 13 is electrically connected to the motor 22; one end of the drive housing 21 is provided with a first slot 211 corresponding to the first buckle 12; one end of the control housing 11 is inserted into one end of the drive housing 21 and is engaged in the first slot 211 by the first buckle 12 to connect the control housing 11 and the drive housing 21 together; a sealing ring 3 is provided at the connection between the control housing 11 and the drive housing 21, one end of the sealing ring 3 abuts against the end face of one end of the control housing 11, and the other end abuts against the motor 22.

[0070] This utility model discloses an integrated drive mechanism in which one end of the control housing 11 is inserted into one end of the drive housing 21 and is engaged in the first slot 211 by the first buckle 12, thereby achieving a tight connection between the control housing 11 and the drive housing 21. The PCB board 13 is electrically connected to the motor 22, thus integrating the control structure 1 and the drive structure 2 into one unit. This reduces the need for external dedicated wiring harnesses and connectors at both ends, lowering component procurement and manufacturing costs. Furthermore, the cooperation between the first buckle 12 and the first slot 211 simplifies the installation process and improves assembly efficiency. In addition, a sealing ring 3 is provided at the connection between the control housing 11 and the drive housing 21. One end of the sealing ring 3 abuts against the end face of one end of the control housing 11, and the other end abuts against the motor 22. This not only fills the assembly gap between the control housing 11 and the drive housing 21, making the connection between them tighter, but also prevents moisture intrusion, improving waterproof performance.

[0071] In this embodiment, as Figure 1-4 As shown, the control housing 11 includes an upper housing 111 and a lower housing 112 connected to the upper housing 111. The first latches 12 are respectively disposed at one end of the upper housing 111 and the lower housing 112. A PCB board 13 is disposed within the internal space formed by the upper housing 111 and the lower housing 112. The number of first latches 12 is two or more, and the number of first slots 211 is the same as the number of first latches 12.

[0072] In this embodiment, as Figure 1-3As shown in Figure 5, one end of the drive housing 21 is also provided with a guide groove 212, and one end of the lower housing 112 is provided with a guide protrusion 1121 corresponding to the guide groove 212. The guide protrusion 1121 is engaged in the guide groove 212 to achieve guidance and alignment between the control housing 11 and the drive housing 21. The guide protrusions 1121 are symmetrically arranged on both sides of one end of the lower housing 112, and the guide groove 212 and the guide protrusion 1121 are in corresponding positions and have the same number.

[0073] In this embodiment, as Figure 1-4 As shown, the outer side wall of the upper housing 111 is provided with a second buckle 1111, and the outer side wall of the lower housing 112 is provided with a connecting seat 1122. The connecting seat 1122 is provided with a second slot 1122a corresponding to the second buckle 1111. The second buckle 1111 engages in the second slot 1122a to connect the upper housing 111 and the lower housing 112 together. Thus, the engagement of the second buckle 1111 with the second slot 1122a on the connecting seat 1122 facilitates the connection of the upper housing 111 and the lower housing 112, making installation convenient.

[0074] In this embodiment, as Figure 1 , 2 As shown in Figure 5, the drive housing 21 is made of an elastic material. One end of the drive housing 21 is also provided with a partition groove 213, which is located on both sides of the first slot 211. During the process of the first buckle 12 engaging with the first slot 211, the partition groove 213 causes an elastic cantilever 214 to form in the area of ​​the first slot 211. The elastic cantilever 214 elastically deforms outward under the pressure of the first buckle 12, and returns to its original position after the first buckle 12 engages with the first slot 211, thus achieving reliable engagement, simplifying assembly operations, and improving assembly efficiency.

[0075] In this embodiment, as Figure 1-5 As shown, the control housing 11 also includes a water guide channel 113, which is respectively disposed at one end of the upper housing 111 and the lower housing 112, and the water guide channels 113 on the upper housing 111 and the lower housing 112 are interconnected. A water outlet 1123 communicating with the water guide channel 113 is provided at the bottom of one end of the lower housing 112. Thus, water that enters the upper housing 111 or the lower housing 112 flows out along the water guide channel 113 through the water outlet 1123 at the bottom of the lower housing 112, preventing water from entering the interior of the upper housing 111 and the lower housing 112, further improving the waterproof performance of the integrated drive mechanism, and preventing the PCB board 13 and the motor 22 from getting damp or short-circuited.

[0076] In this embodiment, as Figure 1-5 As shown, the water guide channels 113 at one end of the upper shell 111 and one end of the lower shell 112 have the same shape and corresponding positions. The water guide channel 113 is formed by a U-shaped water guide channel and a long strip water guide channel communicating with the U-shaped water guide channel. The long strip water guide channels extend to the side wall edges of the upper shell 111 and the lower shell 112. When the upper shell 111 and the lower shell 112 are installed together, the long strip water guide channel of the upper shell 111 and the long strip water guide channel of the lower shell 112 are connected to achieve communication. The water outlet 1123 at the bottom of one end of the lower shell 112 is connected to the U-shaped water guide channel, so that the water that enters the upper shell 111 or the lower shell 112 flows out along the water guide channel 113 and through the water outlet 1123 at the bottom of the lower shell 112.

[0077] In this embodiment, as Figure 1 , 4 As shown, the lower edge of the inner wall of the upper shell 111 is provided with an outward protrusion 1112, and the upper edge of the inner wall of the lower shell 112 is provided with an inner protrusion 1124 and a waterproof platform 1125 extending outward along the inner protrusion 1124. The outward protrusion 1112 engages with the inner protrusion 1124. The outward protrusion 1112 is circumferentially distributed along the lower edge of the inner wall of the upper shell 111, and the inner protrusion 1124 is circumferentially distributed along the upper edge of the inner wall of the lower shell 112. In this way, the mutual engagement of the outward protrusion 1112 and the inner protrusion 1124 improves the airtightness of the joint between the upper shell 111 and the lower shell 112, preventing water from entering the internal space formed by the upper shell 111 and the lower shell 112, and allowing water that intrudes into the joint between the upper shell 111 and the lower shell 112 to flow out along the waterproof platform 1125 and the outer wall of the lower shell 112.

[0078] In this embodiment, as Figure 1-4 As shown in Figure 6, the control structure 1 further includes a wire harness connector 14, which is connected to the PCB board 13. The wire harness connector 14 has a circumferentially arranged water-guiding step 141, and a water-guiding cavity 1126 is provided at the bottom of the other end of the lower housing 112. A water-guiding through hole 1126a is provided within the water-guiding cavity 1126. Water that intrudes into the joint between the upper housing 111, the lower housing 112, and the wire harness connector 14 flows along the water-guiding step 141 under gravity towards the water-guiding through hole 1126a within the water-guiding cavity 1126, and then flows out from the water-guiding through hole 1126a. The wire harness connector 14 is an external interface used for energy and information exchange between the entire integrated drive mechanism and external sources (such as power supplies and control systems).

[0079] In this embodiment, as Figure 1As shown, the PCB board 13 is provided with a connection terminal 131, which is electrically connected to the power supply terminal of the motor 22 to realize the electrical connection between the PCB board 13 and the motor 22. The connection terminal 131 is a pin provided on the PCB board 13, and the pin is electrically connected to the power supply terminal of the motor 22.

[0080] In this embodiment, as Figure 1 , 2 As shown in Figures 7 and 8, the drive structure 2 also includes a mounting base 23, which is disposed at the other end of the drive housing 21.

[0081] In this embodiment, as Figure 1-4 As shown in Figure 7, the outer side wall of the upper housing 111 is provided with a first fixing seat 1113, and the outer side wall of the lower housing 112 is provided with a second fixing seat 1127. The first fixing seat 1113 is provided with a first fixing through hole 1113a, and the second fixing seat 1127 is provided with a second fixing through hole 1127a corresponding to the first fixing through hole 1113a. The integrated drive mechanism is mounted on the external mounting frame 5 by passing a fixing bolt 4 through the first fixing through hole 1113a and the second fixing through hole 1127a, so as to drive the moving parts mounted on the external mounting frame 5 to complete the predetermined action.

[0082] The integrated drive mechanism of this utility model has the following advantages:

[0083] (1) Integrated installation: One end of the control housing 11 is inserted into one end of the drive housing 21 and is snapped into the first slot 211 by the first buckle 12 to achieve a snap-fit ​​connection between the control housing 11 and the drive housing 21. The PCB board 13 is electrically connected to the motor 22, thereby integrating the control structure 1 and the drive structure 2 into one, reducing the external dedicated wiring harness and the connectors at both ends, and reducing the cost of parts procurement and manufacturing.

[0084] (2) The installation steps are simplified and the assembly efficiency is improved: the control housing 11 and the drive housing 21 are clamped together by the cooperation of the first buckle 12 and the first slot 211, which reduces the installation steps and operation time and improves the assembly efficiency.

[0085] (3) Good sealing performance: One end of the sealing ring 3 abuts against the end face of one end of the control housing 11 and the other end abuts against the motor 22. It not only fills the assembly gap between the control housing 11 and the drive housing 21, making the connection between the control housing 11 and the drive housing 21 tighter, but also prevents water intrusion and improves waterproof performance.

[0086] (4) Compact structure: The integrated installation avoids redundant space between the control structure 1 and the drive structure 2, reduces the overall volume occupied, and is conducive to the layout and optimization of the internal space of the equipment.

[0087] (5) Good waterproof performance: Water that enters the upper housing 111 or the lower housing 112 flows out through the water outlet 1123 at the bottom of the lower housing 112 along the water guide groove 113, preventing water from entering the interior of the upper housing 111 and the lower housing 112, further improving the waterproof performance of the integrated drive mechanism, and preventing the PCB board 13 and the motor 22 from getting damp or short-circuited.

[0088] In summary, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0089] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
