Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a universal joint device. Background Technology

[0002] In industrial products, it is often necessary to move internal parts back and forth, such as electric pillows. Currently, electric lead screws or cylinders are used to drive these parts, thus achieving the desired movement. However, some parts require not only linear positional adjustments but also angular adjustments, which electric lead screws or cylinders cannot adequately meet. Therefore, there is an urgent need for a more flexible movement adjustment device. Utility Model Content

[0003] The purpose of this utility model is to provide a universal motion device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] A universal joint includes: a housing with a rotating sleeve rotatably connected inside, the rotating sleeve being threadedly connected to a lead screw; a motor mounted on the housing and drivingly connected to the rotating sleeve; a movable seat connected to the end of the lead screw, a guide rod connected to the movable seat, the guide rod slidingly connected to the housing along the length of the lead screw, and a mounting groove provided on the side of the movable seat away from the housing, the mounting groove containing a universal ball.

[0006] This technical solution has at least the following beneficial effects: Connecting the moving parts to the universal ball joint allows for movement of the parts in a straight line. When needed, the rotating sleeve can be driven by a motor. The rotating sleeve engages with the lead screw, and the movable seat is slidably connected to the housing via a guide rod. This allows the parts to move along the length of the lead screw. Reversing the motor causes the parts to move in the opposite direction. When the parts deflect at an angle during straight-line movement, the universal ball joint provides the deflection freedom, thus adapting to the adjustment needs of the parts' movement. This provides the freedom to adjust the rotation angle, improving the flexibility of power output. Furthermore, the overall structure is compact, better meeting installation and usage requirements.

[0007] As a further improvement to the above technical solution, a receiving groove is provided on the end face of the lead screw near the movable seat, and the universal ball extends into the receiving groove. The mounting groove on the end face of the movable seat and the receiving groove on the end face of the lead screw together form a space that can accommodate and limit the universal ball, thus reducing the thickness required for the movable seat, making the overall structure more compact, and ensuring the stability of the overall installation.

[0008] As a further improvement to the above technical solution, this utility model also includes a connecting plate, wherein a screw passes through the center of the connecting plate, the screw is connected to the universal ball and presses the connecting plate onto the universal ball. The connecting plate can be used to connect to peripheral components. During assembly, the connecting plate can improve the stability of fixing peripheral components to the universal ball, and the screw pressing the connecting plate onto the universal ball ensures a secure connection between the two.

[0009] As a further improvement to the above technical solution, the connecting plate is provided with multiple connecting holes around the screw. These multiple connecting holes facilitate the insertion of connectors to connect to peripheral components, further improving the ease of assembly and use.

[0010] As a further improvement to the above technical solution, the output end of the motor extends into the housing and is connected to a driving gear. A driven gear is connected to the outside of the rotating sleeve. A transmission gear is rotatably connected inside the housing between the driving gear and the driven gear, and the transmission gear meshes with both the driving gear and the driven gear. The motor drives the driving gear to rotate, and the power is transmitted to the driven gear through the transmission gear, thereby driving the rotating sleeve to rotate. By using gears to transmit the motor's power to the rotating sleeve, the installation position of the motor can be easily adjusted to better adapt to usage requirements, and the torque of the rotating sleeve can be easily adjusted, thereby adjusting the output torque of the lead screw.

[0011] As a further improvement to the above technical solution, the inner side of the rotating sleeve is provided with an interconnected internal thread section and a clearance section. The internal thread section meshes with the lead screw, and a movable clearance is provided between the outer side of the lead screw and the inner side of the clearance section. By utilizing the meshing of the internal thread section with the external thread on the outer side of the lead screw, the power of the rotating sleeve is transmitted to the lead screw. The movable clearance between the clearance section on the inner side of the rotating sleeve and the outer side of the lead screw eliminates the need for the entire rotating sleeve to mesh with the lead screw, thus reducing friction and improving the smoothness and accuracy of the lead screw's movement.

[0012] As a further improvement to the above technical solution, the housing includes a bottom housing and a vertical housing connected to the top left side of the bottom housing. The rotating sleeve is rotatably connected inside the vertical housing. The driving gear, driven gear, and transmission gear are respectively located inside the bottom housing, and the motor is connected to the top right side of the bottom housing. In this configuration, the lead screw and motor are arranged side-by-side with spacing, which helps to flatten the overall structure, reduce the space required along the length of the lead screw, and thus better suit different installation application scenarios.

[0013] As a further improvement to the above technical solution, multiple guide rods are arranged around the lead screw. These multiple guide rods can help stabilize the position of the movable seat, further improving the stability and accuracy of the lead screw driving the movable seat to move back and forth.

[0014] As a further improvement to the above technical solution, a connecting lug is provided on the outer side of the housing. When connecting the housing to an external device, a connector can be driven into the connecting lug and connected to the housing, improving the convenience of overall installation.

[0015] As a further improvement to the above technical solution, a protective shell is provided on the outside of the motor, and the protective shell is connected to the housing. The protective shell can provide enveloping protection for the motor, improving the pressure resistance and reliability of the motor position. Attached Figure Description

Detailed Implementation

[0021] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connection relationships mentioned herein do not simply refer to direct connection of components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions.

[0022] Reference Figures 1 to 3 A universal joint device includes: a housing 100, in which a rotating sleeve is rotatably connected, and a lead screw 120 is threadedly connected to the rotating sleeve. In practical applications, ball bearings are connected between the top and bottom positions of the rotating sleeve and the inner side of the housing 100, thereby enabling the rotating sleeve to rotate within the housing 100; a motor 200, which is mounted on the housing 100 and is drivenly connected to the rotating sleeve; a movable seat 300, which is connected to the end of the lead screw 120, and a guide rod 310 is connected to the movable seat 300. The guide rod 310 slides along the length direction of the lead screw 120 and is slidably connected to the housing 100. A mounting groove is provided on the side of the movable seat 300 away from the housing 100, and a universal ball 320 is disposed in the mounting groove.

[0023] In this universal joint device, the parts that need to be moved are connected to the universal ball 320. In use, if it is necessary to move the parts in a straight line, the motor 200 can drive the rotating sleeve to rotate. The rotating sleeve and the lead screw 120 are threaded together, and the movable seat 300 is slidably connected to the housing 100 through the guide rod 310. This allows the parts to move along the length of the lead screw 120. When the motor 200 is rotated in the opposite direction, the parts will move in the opposite direction in a straight line. When the parts move in a straight line and the angle deflection occurs, the universal ball 320 can provide the parts with the degree of freedom of deflection, thereby adapting to the needs of adjusting the movement of the parts. In this way, the universal ball 320 provides the degree of freedom of rotation adjustment angle, improves the flexibility of outputting power, and the overall structure is compact, better meeting the needs of installation and use.

[0024] In the above embodiment, the mounting groove can directly provide space for the universal ball 320. In this case, the movable seat 300 needs to have sufficient depth to accommodate the mounting groove. To make the overall structure more compact, in this embodiment, a receiving groove is provided on the end face of the lead screw 120 near the movable seat 300, and the universal ball 320 extends into the receiving groove. The mounting groove on the end face of the movable seat 300 and the receiving groove on the end face of the lead screw 120 together form a space that can accommodate and limit the universal ball 320. This reduces the required thickness of the movable seat 300, making the overall structure more compact and ensuring the stability of the overall installation.

[0025] Peripheral components can be directly connected to the universal ball joint 320. However, since the universal ball joint 320 is relatively small, and some larger components may be difficult to connect directly, this invention also includes a connecting plate 400. A screw 410 passes through the center of the connecting plate 400, connecting to the universal ball joint 320 and pressing the connecting plate 400 firmly onto it. The connecting plate 400 can be used to connect peripheral components. During assembly, the connecting plate 400 improves the stability of fixing peripheral components to the universal ball joint 320, and the screw 410 presses the connecting plate 400 firmly onto the universal ball joint 320, ensuring a secure connection.

[0026] Furthermore, the connecting plate 400 is provided with a plurality of connecting holes 420 surrounding the screw 410. The plurality of connecting holes 420 facilitate the insertion of connectors to connect to peripheral components, further improving the ease of assembly and use.

[0027] The output end of the motor 200 can be directly connected to the rotating sleeve drive. In this case, the motor 200 and the lead screw 120 need to be arranged in a straight line. In order to improve the flexibility of the overall structural arrangement, in this embodiment, the output end of the motor 200 extends into the housing 100 and is connected to the driving gear 210. The driven gear 230 is connected to the outside of the rotating sleeve. A transmission gear 220 is rotatably connected between the driving gear 210 and the driven gear 230 inside the housing 100. The transmission gear 220 meshes with the driving gear 210 and the driven gear 230 respectively. In practical applications, the transmission gear 220 can be a double gear. In this case, the driving gear 210 and the driven gear 230 mesh with gears of different outer diameters in the double gear respectively. The motor 200 drives the drive gear 210 to rotate, and transmits the power to the driven gear 230 through the transmission gear 220, thereby driving the rotating sleeve to rotate. In this way, the power of the motor 200 is transmitted to the rotating sleeve through the gears, which makes it easy to adjust the installation position of the motor 200 to better meet the usage requirements, and also makes it easy to adjust the torque of the rotating sleeve, thereby adjusting the output torque of the lead screw 120.

[0028] The rotating sleeve can be threadedly engaged with the lead screw 120 in its entirety, or only partially engaged. Specifically, the inner side of the rotating sleeve is provided with an interconnected internal thread section 111 and a clearance section 112. The internal thread section 111 engages with the lead screw 120, and a clearance is provided between the outer side of the lead screw 120 and the inner side of the clearance section 112. By utilizing the engagement between the internal thread section 111 and the external thread of the lead screw 120, the power of the rotating sleeve is transmitted to the lead screw 120. The clearance between the clearance section 112 on the inner side of the rotating sleeve and the outer side of the lead screw 120 eliminates the need for the entire rotating sleeve to engage with the lead screw 120, thus reducing friction and improving the smoothness and accuracy of the lead screw 120's movement.

[0029] In some embodiments, the housing 100 includes a bottom housing 131 and a vertical housing 132 connected to the top left side of the bottom housing 131. The rotating sleeve is rotatably connected to the vertical housing 132. The driving gear 210, driven gear 230, and transmission gear 220 are respectively located inside the bottom housing 131. The motor 200 is connected to the top right side of the bottom housing 131. In this configuration, the lead screw 120 and the motor 200 are arranged side-by-side with spacing, which helps to flatten the overall structure and reduce the space required along the length of the lead screw 120, thus better adapting to different installation application scenarios.

[0030] The guide rod 310 is used to form a sliding connection between the movable seat 300 and the housing 100. Specifically, multiple guide rods 310 are arranged around the lead screw 120. Multiple guide rods 310 can help stabilize the position of the movable seat 300, further improving the stability and accuracy of the movable seat 300 moving back and forth driven by the lead screw 120.

[0031] In some embodiments, a connecting lug 140 is provided on the outer side of the housing 100. When the housing 100 is connected to the structure of an external device, a connector can be driven into the connecting lug 140 and connected to the housing 100, improving the convenience of overall installation.

[0032] In some embodiments, a protective shell 150 is provided on the outside of the motor 200, and the protective shell 150 is connected to the housing 100. The protective shell 150 can provide enclosed protection for the motor 200, improving the pressure resistance and reliability of the motor 200.

[0033] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
