Description

Technical Field

[0001] This utility model relates to the technical field of electric curtain accessories, specifically a control component. Background Technology

[0002] In the prior art, patent publication number CN222296106U discloses a control structure for a Venetian blind, including a drive motor and a control box built into the window frame. The control box contains a battery, and its side has a circumferential groove. A mounting base is embedded in the outer side of the window frame, and the mounting base has a first conductive element electrically connected to the drive motor. A magnetic element and a magnetic guide element are connected within the circumferential groove to allow the control box to be detachably mounted on the mounting base. The control box also has a second conductive element connected to the battery. In the installed state, the first and second conductive elements are in contact to achieve electrical conduction between the control box and the drive motor. Based on this, the battery can be easily charged, and the control box can be easily maintained and replaced in case of failure of the control box or its internal battery, ensuring the normal raising, lowering, and tilting of the Venetian blind.

[0003] The aforementioned patent achieves a detachable connection between the control box and the mounting base through magnetic conductive parts and magnetic suction parts, but the method of relying solely on magnetic adsorption is not secure enough. Utility Model Content

[0004] The technical problem this invention aims to solve is the insufficient firmness of magnetic adsorption alone.

[0005] This utility model solves the above-mentioned technical problems through the following technical solution: a control component, including a control box and a mounting base installed on a window frame, wherein the control box has a receiving cavity, the receiving cavity has a limiting hole, the mounting base has a limiting member, at least part of the limiting member extends into the limiting hole, a gap space is formed between the end of the receiving cavity away from the limiting member and the mounting base, the straight compression distance of the gap space toward the limiting member is greater than or equal to the depth of the limiting member extending into the limiting hole or a rotation space is formed between the limiting member and the window frame to allow the limiting member to disengage from the limiting hole.

[0006] The beneficial effects of this utility model are as follows: By forming a limiting member on one end of the mounting base, and at least part of the limiting member extending into the limiting hole, the limiting member can restrict the control box from moving in the direction away from the magnetic attraction. When the direction of the external force is away from the magnetic attraction, the control box cannot be directly separated from the mounting base, which increases the firmness of the control box on the mounting base and solves the problem of insufficient firmness in the prior art that relies solely on magnetic adsorption. Furthermore, the user can remove the control box from the mounting base by sliding it in a straight line or by rotating the control box upwards.

[0007] Furthermore, the depth to which the limiting member extends into the limiting hole is greater than or equal to half the height of the limiting member.

[0008] Furthermore, the end of the mounting base opposite to the limiting member has an outer chamfered surface.

[0009] Furthermore, the outer chamfered surface is a first inclined surface.

[0010] Furthermore, the end face of the space opposite to the mounting base is formed with a second inclined surface that matches the first inclined surface.

[0011] Furthermore, a first arc-shaped surface is formed on the inner side of the limiting member.

[0012] Furthermore, a second arc-shaped surface adapted to the first arc-shaped surface is formed on the inner side of the limiting hole.

[0013] Furthermore, the gap extends toward the side opposite to the limiting member and penetrates the control box.

[0014] Furthermore, there are two mounting bases arranged side by side.

[0015] Furthermore, one of the mounting bases is electrically connected to the control box. Attached Figure Description

Example

[0030] This utility model discloses a control component, such as Figure 1-6As shown in Figures 9 and 11, the device includes a control box 2 and a mounting base 3 installed on the window frame 1. The control box 2 has a receiving cavity 10, and the receiving cavity 10 has a limiting hole 7. The mounting base 3 has a limiting member 6, and at least part of the limiting member 6 extends into the limiting hole 7. A gap space 12 is formed between the end of the receiving cavity 10 away from the limiting member 6 and the mounting base 3. The straight compression distance of the gap space 12 toward the limiting member 6 is greater than or equal to the depth of the limiting member 6 extending into the limiting hole 7.

[0031] Specifically, such as Figure 1 , 2 As shown, the mounting base 3 is fixedly connected to the window frame 1. The mounting base 3 is installed on the window frame 1 by means of screws, adhesives, etc. Specifically, such as Figure 1 , 2 As shown in Figures 5 and 6, a first magnetic component 4 is installed on the control box 2, and a second magnetic component 5 is installed on the mounting base 3. The control box 2 and the mounting base 3 are attracted to each other through the first magnetic component 4 and the second magnetic component 5. Specifically, one of the first magnetic component 4 and the second magnetic component 5 is a magnet, and the other is an iron component, or both the first magnetic component 4 and the second magnetic component 5 are magnets. The control box 2 is magnetically mounted to the mounting base 3.

[0032] Specifically, the control box 2 has a receiving cavity 10, at least part of the mounting base 3 is located in the receiving cavity 10, and a groove is formed on the back of the control box 2 to form the receiving cavity 10, wherein the back of the control box 2 is the side facing the window frame 1.

[0033] Specifically, Figure 5 In the middle, the limiting hole 7 is opened at the top of the receiving cavity 10, such as Figure 5-6 As shown, a limiting member 6 is formed at the upper end of the mounting base 3, and the limiting member 6 is integrally formed on the mounting base 3. The shape of the limiting member 6 is not limited, but preferably, the limiting member 6 can be in the shape of a protrusion, and at least a portion of the limiting member 6 extends into the limiting hole 7. Figure 5-6 In the middle, the limiting hole 7 opens downwards, and the limiting member 6 extends upwards into the inner side of the limiting hole 7. Through the limiting effect of the limiting member 6 and the limiting hole 7, when the direction of the external force is away from the magnetic attraction direction, the external force cannot directly separate the control box 2 from the mounting base 3, which increases the firmness of the control box 2 on the mounting base 3.

[0034] Due to the setting of the limiting component 6 and the limiting hole 7, when the direction of the external force is opposite to the magnetic attraction direction, the external force cannot directly separate the control box 2 from the mounting base 3.

[0035] In this embodiment, as Figure 5-6As shown, the user pushes the control box 2 upward, causing the control box 2 to move along the linear sliding direction of the interval space 12 toward the limiting member 6. The control box 2 slides upward, compressing the interval space 12. The distance of the linear compression of the interval space 12 toward the limiting member 6 is greater than or equal to the depth of the limiting member 6 extending into the limiting hole 7. Thus, when the user pushes the control box 2 to make the lower end of the receiving cavity 10 contact the lower end of the mounting base 3, the limiting hole 7 and the limiting member 6 have already or just separated relative to each other, so that the control box 2 can be relatively separated from the mounting base 3, thereby allowing the control box 2 to be smoothly removed from the mounting base 3.

[0036] Specifically, after the limiting member 6 disengages from the limiting hole 7, the user moves the control box 2 in the direction away from the magnetic attraction, thereby separating the control box 2 from the mounting base 3 and achieving the purpose of removing the control box 2.

[0037] Specifically, when the control box 2 is installed on the mounting base 3, the control box 2 is electrically connected to the mounting base 3, and the mounting base 3 is electrically connected to the motor inside the window frame 1, so that the control box 2 controls the motor. The control box 2 is provided with a control board 11, and one end of the second conductive element 16 is fixedly connected to the control board 11. The mounting base 3 is provided with a first conductive element 15, and the first conductive element 15 and the second conductive element 16 contact each other to form an electrical connection.

[0038] The contact point between the first conductive element 15 and the second conductive element 16 can be located on the side of the mounting base 3 facing away from the window frame 1, without affecting the upward sliding of the control box 2. When the control box 2 slides upward, the second conductive element 16 slides upward along the surface of the mounting base 3 to disengage from the contact with the first conductive element 15.

[0039] Or such as Figure 5-6 As shown, the contact point between the first conductive element 15 and the second conductive element 16 is located within the mounting base 3. A recessed cavity 17 is formed on the mounting base 3, and the inner bottom wall of the recessed cavity 17 is the end face of the first conductive element 15. The second conductive element 16 is a spring-loaded pin. When the control box 2 is mounted on the mounting base 3, the second conductive element 16 is not in its maximum compressed state. The second conductive element 16 has a chamfered surface facing the limiting member 6, and this chamfered surface can contact and engage with the recessed cavity 17 during the upward movement of the control box 2. This allows the second conductive element 16 to automatically contract in the direction away from the magnetic attraction, and the contraction amount is sufficient to allow the end of the second conductive element 16 closest to the first conductive element 15 to detach from the recessed cavity 17, thus not obstructing the upward movement of the control box 2. When the second conductive element 16 is used as a spring-loaded pin, the elasticity of the second conductive element 16 during the upward movement of the control box 2 relatively reduces the friction between the second conductive element 16 and the surface of the mounting base 3, thereby improving the service life of the second conductive element 16.

[0040] Specifically, the depth to which the limiting member 6 extends into the limiting hole 7 is greater than or equal to half the height of the limiting member 6. For example... Figure 5 , 6As shown, when the depth of the limiting member 6 extending into the limiting hole 7 is greater than or equal to 1 / 2 of the height of the limiting member 6, it can establish a stable and accurate positioning while saving materials, and can provide sufficient strength and rigidity to withstand the expected load.

[0041] Specifically, the mounting base 3 has a first inclined surface 22 formed at one end away from the limiting member 6, and the gap space 12 has a second inclined surface 14 formed at one end away from the mounting base 3, which is adapted to the first inclined surface 22.

[0042] In this embodiment, as Figure 5 , 6 As shown, a first inclined surface 22 is formed at the lower end of the mounting base 3. The first inclined surface 22 extends downward from the side of the mounting base 3 facing the control box 2 to the side facing away from the control box 2. The first inclined surface 22 facilitates the demolding of the mounting base 3. Correspondingly, a second inclined surface 14 is parallel to the first inclined surface 22, so that the distance between the first inclined surface 22 and the second inclined surface 14 is equal everywhere, which facilitates the upward sliding of the control box 2.

[0043] Specifically, the gap 12 extends toward the side opposite to the limiting member 6 and passes through the control box 2.

[0044] In this embodiment, the partition space 12 extends downward and penetrates through the control box 2, so that the lower end of the partition space 12 is open, which saves material. When the lower end of the partition space 12 is open, the vertical length of the partition space 12 increases, providing more space for the receiving cavity 10 in the control box 2 to cooperate with the mounting base 3 and the limiting member 6, resulting in relatively high installation efficiency.

[0045] Specifically, there are two mounting brackets 3 arranged side by side. For example... Figure 11 As shown, two mounting bases 3 are arranged side by side, and correspondingly, the receiving cavities 10 and mounting bases 3 are arranged one-to-one. Preferably, the two receiving cavities 10 are symmetrically distributed about the first central axis of the control box 2. This first central axis is parallel to the direction of linear compression of the space 12 towards the limiting member 6, and the first central axis is arranged vertically upward. The first central axis AA is as follows: Figure 11 As shown, this ensures the balance and stability of the control box 2 when it is installed on the two mounting bases 3.

[0046] Specifically, one of the two mounting bases 3 is electrically connected to the control box 2. When there is only one motor in the window frame 1, only one of the two mounting bases 3 is equipped with a first conductive element 15. The mounting base 3 is electrically connected to the control box 2 through the first conductive element 15 and the second conductive element 16, thereby enabling the control box 2 to control and supply power to the motor.

[0047] Specifically, a USB interface 23 is provided on the receiving cavity 10. For example... Figure 3As shown, a USB interface 23 is provided on the receiving cavity 10, and a battery pack is installed inside the control box 2. The battery pack is used to power the motor, and the control box 2 can be charged by an external power source through the USB interface 23 to ensure that the control box 2 has sufficient power. Furthermore, when the user installs the control box 2 onto the mounting base 3, the USB interface 23 is hidden by the mounting base 3, reducing the possibility of dust or other contaminants entering the USB interface. The control box 2 includes a main shell 21 and a back cover 20. The main shell 21 includes a shell with an opening, and the back cover 20 covers the opening of the main shell 21. The main shell 21 and the back cover 20 are detachably connected by a snap-fit ​​mechanism, and the receiving cavity 10 is formed on the back cover 20. Example

[0048] like Figure 1-4 As shown in Figures 7-11, this utility model provides a control component, including a control box 2 and a mounting base 3 installed on a window frame 1. The control box 2 has a receiving cavity 10, and the receiving cavity 10 has a limiting hole 7. The mounting base 3 has a limiting member 6, at least part of which extends into the limiting hole 7. A gap space 12 is formed between the end of the receiving cavity 10 away from the limiting member 6 and the mounting base 3. A rotation space 13 is formed between the limiting member 6 and the window frame 1.

[0049] Unlike Example 1, as Figure 7 , 8 As shown, when the control box 2 is mounted on the mounting base 3, the second conductive element 16 automatically retracts along the direction away from the magnetic attraction when the control box 2 moves upward. This retraction amount is insufficient to allow the end of the second conductive element 16 near the first conductive element 15 to detach from the recessed cavity 17. Alternatively, if the second conductive element 16 is a rigid pin, it cannot retract along the direction away from the magnetic attraction. Therefore, the second conductive element 16 interferes with the upward movement of the control box 2, preventing the control box 2 from moving directly upward. Using the above embodiment reduces accidental disassembly by non-operators.

[0050] Because of the limiting element 6 and the limiting hole 7, when the direction of the external force is opposite to the magnetic attraction direction, the external force cannot directly separate the control box 2 from the mounting base 3. Therefore, it is necessary to change the direction of the external force when separating the control box 2 and the mounting base 3. However, the second conductive element 16 will interfere with the direct upward linear sliding of the control box 2.

[0051] Since the control box 2 cannot slide upwards in a straight line, when the user disassembles the control box 2, the user first rotates the control box 2 upwards at a certain angle so that the second conductive element 16 is disengaged from the recessed cavity 17, and until the lower end of the control box 2 slides upwards in a straight line without interfering with the mounting base 3. Then, under the action of an upward external force, the control box 2 can move upwards so that the limiting element 6 is disengaged from the control box 2.

[0052] In this embodiment, as Figure 7 , 8As shown, a rotation space 13 is formed between the limiting member 6 and the window frame 1, which allows the upper end of the control box 2 to rotate within the rotation space 13. During the rotation of the control box 2, the gap space 12 between the lower end of the control box 2 and the mounting base 3 ensures that the lower end of the mounting base 3 will not obstruct the rotation of the control box 2. After the user applies external force to rotate the control box 2, the limiting member 6 and the limiting hole 7 can be separated.

[0053] Specifically, the end of the mounting base 3 that is away from the limiting member 6 has an outer chamfered surface.

[0054] In this embodiment, the size of the outer chamfer surface can be determined according to the rotation angle of the control box 2, so as to prevent the control box 2 from interfering with the mounting base 3 during rotation. Preferably, the outer chamfered surface covers the entire bottom of the mounting base 3, that is, the outer chamfered surface extends from the side of the mounting base 3 facing the control box 2 to the side facing away from the control box 2, so as to increase the distance between the side of the mounting base 3 facing the control box 2 and the bottom of the space 12, making it easier to rotate the control box 2 and preventing interference between the control box 2 and the bottom of the mounting base 3. In addition, due to the presence of the outer chamfered surface, the distance from the side of the mounting base 3 away from the control box 2 to the bottom of the space 12 can be appropriately shortened.

[0055] Specifically, in this embodiment, the outer chamfer surface is the first inclined surface 22. Compared with the outer chamfer surface of the arc-shaped surface, the outer chamfer surface of the inclined surface is more convenient for the demolding of the mounting base 3.

[0056] Specifically, a first arc-shaped surface 8 is formed on the inner side of the limiting member 6.

[0057] In this embodiment, a first arcuate surface 8 is formed on the inner side of the limiting member 6, and the inner side of the limiting member 6 refers to the side facing the window frame 1. The first arcuate surface 8 is as follows: Figure 10 As shown, the arc surface of the first arc surface 8 is adapted to the rotation trajectory of the control box 2 as it rotates upward, so that the control box 2 can rotate upward relatively smoothly.

[0058] Specifically, a second arc-shaped surface 9 is formed on the inner side of the limiting hole 7, which is adapted to the first arc-shaped surface 8.

[0059] In this embodiment, as Figure 10 As shown, a second arc-shaped surface 9 is provided on the inner side of the corresponding limiting hole 7. The inner side of the limiting hole 7 refers to the side away from the window frame 1, and the arc surface of the second arc-shaped surface 9 is adapted to the arc surface of the first arc-shaped surface 8. Preferably, the curvature of the second arc-shaped surface 9 is the same as the curvature of the first arc-shaped surface 8.

[0060] In addition, such as Figure 7-9As shown, the first arc-shaped surface 8 formed on the inner side of the limiting member 6 and the second arc-shaped surface 9 on the inner side of the limiting hole 7 can also be replaced by a third inclined surface 24 on the inner side of the limiting member 6 and a fourth inclined surface 25 on the inner side of the limiting hole 7 facing the limiting member 6. The inclination direction of the third inclined surface 24 and the fourth inclined surface 25 is both upward from the inner side of the limiting member 6 to the inner side of the limiting hole 7. An inclination angle is formed between the third inclined surface 24 and the fourth inclined surface 25. Preferably, this inclination angle is consistent with the inclination angle of the control box 2 relative to the mounting base 3 after rotation. When rotating control box 2, as Figure 7 As shown, the control box 2 can first rotate a certain angle. At this time, the second conductive element 16 disengages from the recessed cavity 17, but before the control box 2 rotates to slide upwards in a straight line, the lower end of the mounting base 3 does not interfere with the upward movement of the control box 2. The control box 2 continues to rotate until the lower end of the control box 2 slides upwards in a straight line without interfering with the mounting base 3. During the rotation of the control box 2, under the action of the third inclined surface 24 and the fourth inclined surface 25, the control box 2 slides upwards. Therefore, during the rotation of the control box 2, the overall movement process of the control box 2 is a combination of rotational upwards and sliding upwards. Finally, it presents the following... Figure 8 The state shown is as indicated. At this point, the user can slide the control box 2 upwards in an inclined position to detach the control box 2 from the mounting base 3.

[0061] Specifically, the gap 12 extends toward the side opposite to the limiting member 6 and passes through the control box 2.

[0062] In this embodiment, when the lower end of the partition space 12 is closed, the size of the partition space 12 is such that the control box 2 does not interfere with the mounting base 3 when it rotates upward. When the lower end of the partition space 12 is open, the distance between the mounting base 3 and the bottom of the partition space 12 is increased, making it easier for the control box 2 to rotate.
