Abstract
Description
Technical Field
[0001] The utility model relates to an electric curtain device, in particular to a connection structure between a curtain motor and a transmission box. Background Art
[0002] With the development of intelligent home, people increasingly use electric curtains to open and close the curtains. The electric curtain mainly consists of a motor and a track. One end of the track is connected with a transmission box, and they are fixedly installed on the wall together; while the motor is installed in a machine box, and a gear set and other transmission components are also installed at one end of the machine box. This end of the machine box is called the motor head; an installation groove matched with the motor head is arranged on the transmission box, and the motor head is detachably installed in the installation groove, thereby fixing the machine box and connecting the transmission components with the transmission box to drive the guide rail to move, so as to open and close the curtain.
[0003] Both the motor head and the installation groove of the transmission box of this kind of electric curtain are circular, and clamping blocks that are engaged and fixed with each other are arranged on the outer wall of the motor head and in the installation groove. During installation, the staff inserts the motor head into the installation groove and then rotates it to make the two engage and fix. However, due to the clamping blocks being prone to cause obstruction and the lack of effective positioning connection, when the staff inserts the motor head into the installation groove, they must carefully twist it left and right, and find the accurate position by feeling before clamping it tightly, resulting in relatively troublesome operation. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a connection structure between a curtain motor and a transmission box to improve the convenience of installation and disassembly.
[0005] The connection structure between the curtain motor and the transmission box described in the utility model includes a machine box and a transmission box. A machine head cover is installed at one end of the machine box, and the transmission components connected with the motor are installed in the machine head cover. The cross-sectional shape of the machine head cover is a water droplet shape with both ends being arc-shaped. A concave installation groove for connecting with the machine head cover is arranged on the transmission box. The cross-sectional shape of the installation groove is a water droplet shape matching the machine head cover, and a rotation allowance space is left between the two sides of the water droplet shape of the installation groove and the two sides of the machine head cover; clamping blocks that are engaged and fixed with each other are arranged circumferentially and oppositely between the outer wall of the machine head cover and the inner wall of the installation groove.
[0006] Furthermore, a concave clamping hole is arranged at the end face of the machine box facing the transmission box. A clamping member is installed in the transmission box. One end of the clamping member can pass through the transmission box and be inserted into the clamping hole. An elastic member for applying a force towards the clamping hole to the clamping member is also installed in the transmission box.
[0007] Furthermore, the machine box includes a shell with an open end and an end cover for closing the open end of the shell. A plurality of screw holes for inserting screws are opened on the end cover. The screws pass through the screw holes and are screwed with the shell, and at least one screw hole is a clamping hole.
[0008] Furthermore, a positioning hole is opened on the transmission box opposite to the clamping hole, and an insertion hole is opened on the transmission box opposite to the outer side of the machine box side wall; the clamping member includes a positioning rod and an insertion rod passing through the positioning hole and the insertion hole respectively, and the positioning rod and the insertion rod are fixedly connected by a connecting rod.
[0009] Furthermore, the transmission box includes a box shell with an accommodating space arranged inside and an opening at the top, and a box cover capable of closing the opening of the box shell.
[0010] Furthermore, the elastic member is a spring, and two ends of the spring are respectively connected to the insertion rod and the box cover.
[0011] The curtain motor transmission box connection structure described in the utility model is that the machine box is fixed in the installation groove of the transmission box through the machine head cover, and the transmission components between the machine box and the transmission box are connected to each other, so that the curtain can be driven to open and close by the motor; the outer contour of the cross section of the machine head cover is in the shape of a water drop, and the installation groove of the transmission box is also in the shape of a water drop, and the diameter is slightly larger than the machine head cover so that it can be sleeved outside the machine head cover, and the blocks arranged between the two are mutually engaged and fixed, and at the same time, the two sides of the water drop shape of the installation groove expand outward to form a space for making way, so that a certain degree of rotation can be formed between the installation groove and the machine head cover. When the machine box is installed on the transmission box, the machine head cover is opposite to the installation groove, and the water drop shape is used for positioning, so that the machine head cover and the installation groove are staggered by a certain position to meet the insertion needs of the blocks between the two, and then the machine box is rotated by a certain angle so that the two ends of the water drop shape are opposite, and the blocks between the two are smoothly clamped, and the installation work can be completed. Therefore, through the setting of this curtain motor transmission box connection structure, the convenience and work efficiency of assembly and disassembly operations can be improved.

[0018] The present utility model provides a connection structure for a curtain motor transmission box.
[0019] The connection structure of the curtain motor transmission box in this embodiment includes a machine box 1 and a transmission box 2. One end of the machine box is provided with a machine head cover 3. A transmission component connected to the motor is installed inside the machine head cover. The cross-sectional shape of the machine head cover is a water droplet shape with both ends being arc-shaped. A mounting groove 21 for connecting with the machine head cover is recessed on the transmission box. The cross-sectional shape of the mounting groove is a water droplet shape matching the machine head cover, and there is a clearance space for relative rotation between the two sides of the water droplet shape of the mounting groove and the two sides of the machine head cover; mutually engaging and fixing blocks 5 are circumferentially arranged between the outer wall of the machine head cover and the inner wall of the mounting groove.
[0020] The described connection structure of the curtain motor transmission box. The machine box is fixed in the installation groove of the transmission box through the machine head cover, and the transmission components between the machine box and the transmission box are interconnected, so that the curtain can be opened and closed by the motor drive; the outer contour shape of the cross-section of the machine head cover is an arc with different diameters at both ends and different center positions, and the end with the larger diameter is the major arc while the end with the smaller diameter is the minor arc, and the ends of the two arcs are connected by a straight line, which can be the tangent of the two arcs, thus forming a machine head cover in the shape of a water droplet; the installation groove of the transmission box is also in the shape of a water droplet, and the diameter is slightly larger than that of the machine head cover so that it can be sleeved outside the machine head cover, and they are fixed by clamping blocks arranged between them. At the same time, on both sides of the water droplet shape of the installation groove, that is, opposite to the tangent of the outer contour of the machine head cover, a relief space is extended outwards, so that a certain degree of rotation can be formed between the installation groove and the machine head cover. When installing the machine box onto the transmission box, align the machine head cover with the installation groove, use the water droplet-shaped outer shape for positioning, stagger the machine head cover and the installation groove by a certain position to meet the insertion requirement of the clamping blocks between them, and then rotate the machine box by a certain angle so that the two ends of the water droplet shape are opposite, and the clamping blocks between them are tightly clamped, then the installation work can be completed.
[0021] For the connection structure of the curtain motor transmission box, a concave clamping hole 11 is provided at the end face of the machine box 1 facing the transmission box. A clamping member 6 is installed inside the transmission box 2. One end of the clamping member can pass through the transmission box and be inserted into the clamping hole. An elastic member 7 that applies a force towards the clamping hole to the clamping member is also installed inside the transmission box. This enables the clamping member to continuously press against the end face of the machine box when the machine box is installed. Until the machine box rotates into place, the clamping member is inserted into the clamping hole to form a limit, thereby improving the connection strength of the machine box. The machine box 1 includes a housing 12 with an open end and an end cover 13 that closes the open end of the housing, so as to install components such as motors and transmission components. A number of screw holes for inserting screws are provided on the end cover. The screws pass through the screw holes and are screwed to the housing, thereby fixing the end cover and the housing to each other. At the same time, at least one screw hole is the clamping hole 11. This can not only reduce the need for hole positions but also use the clamping member as a limiting member for the screws, further improving the connection strength. Similarly, the transmission box 2 includes a box shell 23 with an internal accommodation space and an open top, and a box cover 24 that can close the opening of the box shell, so as to install the internal parts. In addition, a positioning hole is provided on the transmission box 2 opposite to the clamping hole 11, and an insertion hole is provided on the transmission box 2 opposite to the outer side of the side wall of the machine box 1. The clamping member 6 includes a positioning rod 61 and an insertion rod 62 that respectively pass through the positioning hole and the insertion hole. The positioning rod and the insertion rod are fixedly connected by a connecting rod 63. The positioning rod passes through the positioning hole and cooperates with the clamping hole to form a fixation. However, if there is only the positioning rod, when the machine box needs to be disassembled for maintenance, it cannot be smoothly removed. Therefore, an insertion rod is provided on one side of the positioning rod, and the end of the insertion rod protrudes outside the transmission box and outside the machine box. When the staff pushes the insertion rod in, the insertion rod can be driven to withdraw from the clamping hole, so that the machine box can be conveniently and smoothly removed. Further, the elastic member 7 can be a spring, which has a simple structure and stable operation. The two ends of the spring are respectively connected to the insertion rod 62 and the box cover 24 to ensure the accuracy of the installation and disassembly operations.
[0022] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
