Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a sofa angle adjustment motor. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy and is widely used in industries such as manufacturing, home appliances, automobiles, and robotics. The sofa angle adjustment motor is a core component of electric or functional sofas, used to control the tilt angle of the backrest and footrest to provide users with a comfortable sitting or lying experience.

[0003] The attached diagram of the instruction manual Figure 8 The image shows a schematic diagram of a sofa support structure in the prior art, including a seat plate. Support legs are fixedly mounted in a rectangular array on the bottom of the seat plate. A leg rest is hinged between two support legs. A backrest is hinged to the end of the seat plate away from the leg rest and located between the two support legs. A slider is slidably mounted vertically on the bottom of the seat plate. A threaded post, rotatably connected to the bottom of the seat plate, is threaded through the slider in a vertical direction. Hinges are hinged to both sides of the slider, with the other ends of the two hinges respectively hinged to the leg rest and the backrest. A reinforcing rod is fixedly connected between the two support legs on the same side of the leg rest. In use… The threaded column rotates at the bottom of the seat plate, causing the slider to slide vertically at the bottom of the seat plate. At this time, the two hinge rods rotate on both sides of the slider, and the other ends of the two hinge rods rotate between the leg support plate and the back support plate, respectively. This allows the leg support plate and the back support plate to rotate on the seat plate in an inclined position, thereby achieving the effect of adjusting the tilt angle of the leg support plate and the back support plate. However, when installing the motor in this sofa frame, the output shaft of the motor is first fixed to the threaded column using a coupling, the motor is fixed using the bracket, and then the two ends of the bracket are fixed to the two reinforcing rods to complete the installation of the motor.

[0004] However, since the height between the reinforcing rod and the bottom of the threaded column on different models of sofa frames is mostly different, it is necessary to equip various different specifications of brackets for motor installation, which is quite inconvenient.

[0005] Therefore, this application proposes a sofa angle adjustment motor. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Example 1

[0034] To address the technical problems in the background section, the following sofa angle adjustment motor is provided:

[0035] Combination Figures 1-7 As shown, the present invention provides a sofa angle adjustment motor, including a fixed base 1 and a sofa support 4 for mounting the fixed base 1. Vertical guide rods 11 are symmetrically and movably passed through the fixed base 1. Mounting seats 12 are fixedly installed on the top of the two guide rods 11. A driving member 13 is installed on the fixed base 1 for driving the mounting seats 12 to slide along the guide rods 11 or stopping the sliding.

[0036] The fixed base 1 is symmetrically equipped with telescopic mechanisms 2 on both sides, and a positioning mechanism 3 is installed at the end of the telescopic mechanism 2. The telescopic mechanism 2 is used to move the positioning mechanism 3 closer to or further away from the fixed base 1. The sofa support 4 includes a seat plate 41. Support legs 42 are fixedly installed in a rectangular array at the bottom of the seat plate 41. A leg support plate 43 is hinged between two support legs 42. A back support plate 44 is hinged at the end of the seat plate 41 away from the leg support plate 43 and located between two support legs 42. A slider 45 is slidably installed vertically at the bottom of the seat plate 41. A threaded post 46 that is rotatably connected to the bottom of the seat plate 41 is threaded vertically through the slider 45. Hinges 47 are hinged on both sides of the slider 45. The other ends of the two hinges 47 are respectively hinged to the leg support plate 43 and the back support plate 44. A reinforcing rod 48 is fixedly connected between two support legs 42 located on the same side of the leg support plate 43. The two sets of positioning mechanisms 3 can be used to position or cancel the positioning between the two sets of telescopic mechanisms 2 and the two reinforcing rods 48 respectively.

[0037] The mounting base 12 is equipped with a motor body 5, which includes a motor housing 51 mounted on the mounting base 12. One end of the motor housing 51 is provided with a vertical output shaft 52. In this embodiment, a worm gear is coaxially fixed to the output end of the motor housing 51. A protective shell is fixedly mounted on the motor housing 51 and sleeved outside the worm gear by screws. The output shaft 52 passes through one side of the protective shell and is rotatably connected to the protective shell. A worm wheel that meshes with the worm gear is coaxially fixed to one end of the output shaft 52 located inside the protective shell. Through the design of the worm wheel and the worm gear, a mechanical locking effect is achieved on the output shaft 52. The output shaft 52 is fixedly connected to the threaded column 46 through a coupling 53.

[0038] By designing the fixed base 1, mounting base 12, driving component 13, telescopic mechanism 2, and positioning mechanism 3, when installing the motor body 5, the output shaft 52 and the threaded column 46 are fixed using the coupling 53. At this time, the mounting base 12 slides along the guide rod 11 through the driving component 13, so that the two sets of positioning mechanisms 3 are respectively facing the two reinforcing rods 48. Then, the two sets of telescopic mechanisms 2 are used to move the two sets of positioning mechanisms 3 away from the fixed base 1, so that the two sets of positioning mechanisms 3 contact the two reinforcing rods 48 respectively. The two sets of positioning mechanisms 3 position the two sets of telescopic mechanisms 2 between the two reinforcing rods 48 respectively, thereby positioning the fixed base 1. Thus, the motor body 5 can be installed and fixed. Through the design of the fixed base 1, mounting base 12, and driving component 13, the height position of the two sets of positioning mechanisms 3 can be adjusted according to the height between the bottom of the reinforcing rod 48 and the threaded column 46, improving applicability. Therefore, it is more convenient to install motors without the need for various different specifications of motor mounting brackets.

[0039] Example 2

[0040] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0041] In this embodiment, the driving member 13 includes a driving rod 131 that is vertical and threaded through the fixed base 1. The driving rod 131 is rotatably connected to the bottom of the mounting base 12. In use, a rotational force is applied to the driving rod 131, causing the driving rod 131 to move spirally on the fixed base 1. At this time, the driving rod 131 rotates with the mounting base 12, thereby allowing the mounting base 12 to slide along the guide rod 11. The operation is simple.

[0042] In this embodiment, the telescopic mechanism 2 includes a housing 21 fixedly installed on one side of the fixed base 1. A horizontal square rod 22 is fixedly installed inside the housing 21. A threaded rod 23 is movably inserted through the end of the housing 21 away from the fixed base 1, and the threaded rod 23 is slidably connected to the square rod 22. A threaded sleeve 24 is threadedly fitted on the outside of the threaded rod 23, and the threaded sleeve 24 is rotatably connected to the end of the housing 21 away from the fixed base 1. The positioning mechanism 3 is installed at the end of the threaded rod 23. In use, a force is applied to the threaded sleeve 24, causing it to rotate at the end of the housing 21. Since the threaded rod 23 is slidably connected to the square rod 22, a guiding effect is achieved on the threaded rod 23. Therefore, when the threaded sleeve 24 rotates on the housing 21, it can drive the threaded rod 23 to slide along the housing 21 towards its interior or exterior, thereby achieving the effect of moving the positioning mechanism 3 closer to or away from the fixed base 1, which is convenient for operation.

[0043] In this embodiment, the positioning mechanism 3 includes a positioning plate 31 fixedly installed at the end of the threaded rod 23. A clamping plate 32 is symmetrically slidably installed on the side of the positioning plate 31 away from the threaded rod 23. A bidirectional threaded rod 33 is rotatably installed on the positioning plate 31, and both clamping plates 32 are threadedly connected to the bidirectional threaded rod 33. In use, when fixing the telescopic mechanism 2 and the reinforcing rod 48, rotating the bidirectional threaded rod 33 causes the two clamping plates 32 to slide in opposite directions on the positioning plate 31, moving away from each other. This positions the two clamping plates 32 above and below the reinforcing rod 48, respectively. The telescopic mechanism 2 causes the positioning plate 31 to abut against the side wall of the reinforcing rod 48. At this time, the two clamping plates 32 are located above and below the reinforcing rod 48, respectively. Reverse rotation of the bidirectional threaded rod 33 causes the two clamping plates 32 to slide in opposite directions on the positioning plate 31, bringing them closer together. This allows the two clamping plates 32 to clamp the reinforcing rod 48, achieving the desired fixation between the telescopic mechanism 2 and the reinforcing rod 48. The operation is simple.

[0044] Example 3

[0045] like Figures 1-7 As shown, based on the above embodiments, this embodiment further provides the following:

[0046] In this embodiment, the mounting base 12 includes a base 121 fixedly mounted on the top of two guide rods 11. A vertical plate 122 is fixedly mounted on the base 121, and a fixing mechanism 123 is mounted on the plate 122. The motor body 5 is detachably mounted on the fixing mechanism 123. With the design that the motor body 5 is detachably mounted on the fixing mechanism 123, when the motor body 5 is damaged and needs to be repaired or replaced, the fixing mechanism 123 can be removed from the motor body 5, and then the fixing between the coupling 53 and the output shaft 52 can be removed, so that the motor body 5 can be disassembled, which facilitates the disassembly of the motor body 5 and thus facilitates the repair or replacement of the motor body 5.

[0047] In this embodiment, the fixing mechanism 123 includes a connecting plate 1231 installed on one side of the upright plate 122. A lower fixing ring 1232 is fixedly installed at the bottom position of the connecting plate 1231 on the side away from the upright plate 122. A fixing plate 1233 is fixedly installed on the side of the connecting plate 1231 away from the upright plate 122 and directly above the lower fixing ring 1232. A guide post 1234 is vertically movably inserted through the fixing plate 1233. An upper fixing ring 1235 is fixedly installed at the bottom of the guide post 1234. A threaded rod 1236, which is rotatably connected to the upper fixing ring 1235, is vertically threaded through the fixing plate 1233. It should be noted that: the upper fixing ring 1235 and the lower fixing ring 1232 are both arc-shaped on opposite sides. When fixing the motor body 5, the motor housing 51 is positioned between the opposite sides of the upper fixing ring 1235 and the lower fixing ring 1232, and the top arc surface of the motor housing 51 contacts the lower fixing ring 1232. At this time, rotating the threaded rod 1236 causes the upper fixing ring 1235 to move downward along the guide post 1234, so that the upper fixing ring 1235 abuts against the top of the motor housing 51. The motor housing 51 can be clamped and fixed by the upper fixing ring 1235 and the lower fixing ring 1232, thereby achieving the positioning effect of the motor body 5.

[0048] In this embodiment, the connecting plate 1231 is rotatably mounted on one side of the upright plate 122 via the rotating shaft 6. Specifically, the rotating shaft 6 is horizontal, and an adjusting member 7 is installed on the upright plate 122 to act on the rotating shaft 6. This adjusting member 7 is used to make the rotating shaft 6 rotate or stop rotating on the upright plate 122. With the special design of the connecting plate 1231 being rotatably mounted on one side of the upright plate 122 via the rotating shaft 6, in use, the rotating shaft 6 is rotated on the upright plate 122 by adjusting the adjusting member 7, which drives the connecting plate 1231 to rotate around the rotating shaft 6, thereby adjusting the axial direction of the output shaft 52, further meeting installation requirements and increasing the applicability of this device.

[0049] In this embodiment, the adjusting component 7 includes a worm gear 71 coaxially fixed to the rotating shaft 6, and a worm 72 meshing with the worm gear 71 is rotatably mounted on the vertical plate 122. In use, applying a rotational force to the worm 72 will drive the rotating shaft 6 to rotate on the vertical plate 122 through the worm gear 71. The operation is simple. Since the meshing of the worm gear 71 and the worm 72 has a self-locking property, the position of the rotating shaft 6 can be fixed when the worm 72 is not rotated, which is convenient for use.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
