Description

Technical Field

[0001] This utility model relates to a window opener, and more particularly to a control panel mounting mechanism for a window opener and the window opener itself. Background Technology

[0002] Existing window openers, as shown in patent 201710140143.6, generally consist of an outer cylinder, a lead screw motor, and a circuit board. During installation, the lead screw motor is fixed to the outer cylinder with screws. Then, the circuit board, which houses the control chip, is directly inserted into the outer cylinder behind the lead screw motor after wiring. Finally, a cap is screwed in to cover it. However, this structure has two drawbacks. First, the control chip is prone to damage during use, and it is difficult for ordinary users to replace the chip individually, increasing the difficulty of later maintenance for manufacturers. Second, fixing the lead screw motor with screws exposes the screw heads on the surface of the outer cylinder, reducing the overall aesthetics of the window opener.

[0003] Therefore, a window opener is needed that allows users to easily perform later repairs and remove screw heads from the surface of the outer cylinder. Utility Model Content

[0004] The purpose of this invention is to provide a control board mounting mechanism for a window opener and a window opener itself. It allows users to easily replace the control chip and circuit board, and removes the fixing screws from the surface of the window opener.

[0005] The technical solution of this utility model is as follows: A control board mounting mechanism for a window opener and a window opener, including an outer cylinder, a stepped section formed in the middle of the outer cylinder, a first mounting hole formed on one side of the stepped section, a lead screw motor installed in the first mounting hole, one end of the lead screw motor abutting against the stepped section, and a circuit board mounting bracket located in the first mounting hole at the other end of the lead screw motor. A circuit board is detachably connected to the circuit board mounting bracket, and the two sides of the circuit board are connected to the power lines of the lead screw motor and the window opener via wiring terminals. A first cap threadedly connected to the outer cylinder is provided at the end of the circuit board mounting bracket away from the lead screw motor. The first cap, the circuit board mounting bracket, and the lead screw motor are sequentially attached to each other.

[0006] In the aforementioned window opener control board mounting mechanism, a wave spring is provided between the first cap and the circuit board mounting bracket. The wave spring is used to compress the circuit board mounting bracket after the first cap is tightened, so that the circuit board mounting bracket and the lead screw motor are compressed to form a rotation limit.

[0007] In the aforementioned window opener control board mounting mechanism, one end of the lead screw motor is fixedly connected to a limiting sleeve, and the limiting sleeve is engaged with the step portion on the side away from the lead screw motor.

[0008] In the aforementioned window opener control board mounting mechanism, a control chip is inserted into the circuit board.

[0009] A window opener is also provided, which includes the aforementioned window opener control panel mounting mechanism.

[0010] In the aforementioned window opener, the outer cylinder has a second mounting hole on the side away from the first mounting hole. The lead screw of the lead screw motor extends into the second mounting hole and is connected to a lead screw pair. A telescopic tube is threaded onto the lead screw pair. One end of the telescopic tube extends to the outer side of the end of the outer cylinder. The telescopic tube is slidably connected to the outer cylinder via a second cap at the end away from the first cap.

[0011] Compared with the prior art, this utility model has the following characteristics:

[0012] (1) This utility model fixes the control chip on the circuit board and connects the power lines on both sides to the circuit board through the terminals, so that the user can directly replace the control chip by inserting it in the later stage, or replace the circuit board as a whole after removing it from the circuit board mounting bracket, thereby effectively reducing the difficulty of later maintenance of the window opener; through the structural cooperation of the step part, the circuit board mounting bracket and the first cap, the screw motor can be squeezed and fixed from both ends to prevent the axial movement or rotation of the screw motor; under the above cooperation, the screw motor does not need to be fixed with screws, that is, the screw structure on the surface of the outer cylinder is removed, improving the overall aesthetics of the window opener;

[0013] (2) By fixing the circuit board with the circuit board mounting bracket, the circuit board 6 can also be kept in a fixed state. That is, on the one hand, the vibration and noise of the circuit board during transportation and use are avoided, and on the other hand, the loosening and disconnection of the connecting wires caused by the vibration of the circuit board are prevented, thus improving the fixing effect of the circuit board.

[0014] (3) Based on the above, by fastening the end of the lead screw motor to the step part through the limiting sleeve, the limiting sleeve can also be used to achieve hard limiting of the lead screw motor, thereby further improving the fixing and anti-rotation effect of the lead screw motor.

[0015] Therefore, this utility model allows users to easily replace the control chip and circuit board, and remove the fixing screws on the surface of the window opener. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0022] Example 1. A control panel mounting mechanism for a window opener, configured as follows: Figure 1 As shown, the device includes an outer cylinder 1, with a stepped portion 2 formed in the middle of the outer cylinder 1. The stepped portion 2 is shaped like an annular retaining ring, which is snapped into the outer cylinder 1 or integrally formed with the outer cylinder 1. A first mounting hole 3 is formed on one side of the stepped portion 2, and a lead screw motor 4 is installed in the first mounting hole 3. One end of the lead screw motor 4 abuts against the stepped portion 2, and the other end of the lead screw motor 4 is provided with a circuit board mounting bracket 5 located in the first mounting hole 3. A circuit board 6 is screwed onto the circuit board mounting bracket 5. The two sides of the circuit board 6 are connected to the power cord of the lead screw motor 4 and the power cord of the window opener via wiring terminals. A first cap 7 is threadedly connected to the outer cylinder 1 at the end of the circuit board mounting bracket 5 away from the lead screw motor 4. The first cap 7, the circuit board mounting bracket 5, and the lead screw motor 4 are sequentially attached to each other.

[0023] A rubber pad can be added between the lead screw motor 4 and the step section 2 as needed.

[0024] The circuit board mounting bracket 5 includes a mounting plate with a T-shaped cross section. The middle part of the mounting plate is detachably connected to the circuit board 6. Two symmetrical round tubes are glued to both ends of the mounting plate. The round tubes and the outer cylinder 1 are nested together and fit together.

[0025] A wave spring 8 is provided between the first cap 7 and the circuit board mounting bracket 5. The wave spring 8 is used to compress the circuit board mounting bracket 5 after the first cap 7 is tightened, so that the circuit board mounting bracket 5 and the lead screw motor 4 are compressed to form a rotation limit.

[0026] The circuit board 6 can be connected to the control chip via a plug-in connection. The control chip is a conventional plug-in window opener control chip. Alternatively, the manufacturer can directly fix the control chip onto the circuit board 6 as needed, so that the circuit board 6 and the control chip can be removed and replaced together during later maintenance.

[0027] In this embodiment, during installation, the circuit board 6 is first mounted on the circuit board mounting bracket 5. Then, the power cords of the lead screw motor 4 and the window opener are connected to the circuit board 6 via wiring terminals to achieve power supply. After wiring, the lead screw motor 4 and the circuit board mounting bracket 5 are inserted into the first mounting hole 3 of the outer cylinder 1. Then, the wave spring 8 is placed in and the first cap 7 is screwed in. By tightening the first cap 7, the wave spring 8 is compressed, and after being deformed by compression, the wave spring 8 applies an inward compressive force to the lead screw motor 4 through the circuit board mounting bracket 5. Under this compressive force, the lead screw motor 4 fits tightly against the step 2 to achieve a limiting function.

[0028] With the above-mentioned coordination, this embodiment enables, on the one hand, the power cords to be connected to the circuit board 6 via plug-in connections, and the circuit board 6 to be screwed onto the circuit board mounting bracket 5. This allows the user to easily replace the circuit board 6 by unscrewing the first cap 7 when it is damaged, reducing the difficulty of later maintenance of the window opener. On the other hand, after the circuit board mounting bracket 5 is installed, it can also work with the wave spring 8 and the first cap 7 to compress and fix the lead screw motor 4, thereby eliminating the need for the existing screw structure used to fix the lead screw motor 4, improving the overall aesthetics and waterproof performance of the window opener.

[0029] Example 2. Window opener, configured as follows: Figure 2 As shown, the window opener includes the window opener control panel mounting mechanism of Embodiment 1, wherein the outer cylinder 1 forms a second mounting hole 10 on the side away from the first mounting hole 3, the stepped portion 2 is located at the connection between the first mounting hole 3 and the second mounting hole 10, the lead screw of the lead screw motor 4 extends into the second mounting hole 10 and is connected to a lead screw pair 11, a telescopic tube 12 is threaded onto the lead screw pair 11, one end of the telescopic tube 12 extends to the outer side of the end of the outer cylinder 1, and the telescopic tube 12 is slidably connected to the outer cylinder 1 via a second cap 13 at the end away from the first cap 7.

[0030] Both ends of the lead screw assembly 11 are connected to rubber pads.

[0031] This embodiment, by defining the structure of the window opener, enables the control board mounting mechanism for the window opener in Embodiment 1 to be stably applied in the window opener.

[0032] Example 3. A control panel mounting mechanism for a window opener, configured as follows: Figure 3As shown, the device includes an outer cylinder 1, with a stepped portion 2 formed in the middle of the outer cylinder 1. A first mounting hole 3 is formed on one side of the stepped portion 2, and a second mounting hole 10 is formed on the other side of the stepped portion 2. The diameter of the second mounting hole 10 is smaller than that of the first mounting hole 3, and a stepped portion 2 is formed at the connection. A lead screw motor 4 is installed in the first mounting hole 3. One end of the lead screw motor 4 abuts against the stepped portion 2. The other end of the lead screw motor 4 is provided with a circuit board mounting bracket 5 located in the first mounting hole 3. A circuit board 6 is detachably connected to the circuit board mounting bracket 5. A control chip is fixedly connected to the circuit board 6. The two sides of the circuit board 6 are connected to the power lines of the lead screw motor 4 and the window opener via wiring terminals. A first cap 7 is provided at the end of the circuit board mounting bracket 5 away from the lead screw motor 4, which is threaded to the outer cylinder 1. The first cap 7, the circuit board mounting bracket 5, and the lead screw motor 4 are sequentially attached to each other.

[0033] The circuit board mounting bracket 5 includes a mounting plate with a T-shaped cross section. The middle part of the mounting plate is detachably connected to the circuit board 6. Two symmetrical round tubes are glued to both ends of the mounting plate. The round tubes and the outer cylinder 1 are nested together and fit together.

[0034] A retaining ring is fastened to the inner part of the stepped portion 2. The retaining ring and the outer cylinder 1 are welded or glued to each other. The retaining ring is provided with a groove.

[0035] One end of the lead screw motor 4 is connected by a screw, fastening, or adhesive to a limiting sleeve 9. One side of the limiting sleeve 9 is provided with a locking block with a mating groove. On the side away from the lead screw motor 4, the limiting sleeve 9 is fastened to the retaining ring through the locking block and the groove, thereby using the cooperation of the limiting sleeve 9 and the retaining ring to limit the rotation of the lead screw motor 4.

[0036] Compared with Embodiment 1, this embodiment, through the coordinated arrangement of the step portion 2, the retaining ring and the limiting sleeve 9, can achieve a rigid limit on the lead screw motor 4, thereby improving the anti-rotation effect of the lead screw motor 4 and facilitating the user's disassembly and assembly of the first cap 7.

[0037] Manufacturers can also install the retaining ring by directly snapping it into the outer cylinder 1 and fixing it, thereby removing the stepped part 2 in the middle of the outer cylinder 1 and reducing the processing difficulty of the outer cylinder 1.

[0038] Example 4. Window opener, configured as follows: Figure 4 As shown, the window opener includes the window opener control panel mounting mechanism in embodiment 3, wherein the lead screw of the lead screw motor 4 extends into the second mounting hole 10 and is connected to the lead screw pair 11, and the lead screw pair 11 is threadedly connected to the telescopic tube 12, one end of the telescopic tube 12 extends to the outer side of the end of the outer cylinder 1, and the telescopic tube 12 is slidably connected to the outer cylinder 1 via the second cap 13 at the end away from the first cap 7.

[0039] Both ends of the lead screw assembly 11 are connected to rubber pads.

[0040] This embodiment, by defining the structure of the window opener, enables the control board mounting mechanism for the window opener in Embodiment 3 to be stably applied in the window opener.
