Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motor circuit boards for venetian blinds, and particularly relates to a support shell for a motor circuit board of a venetian blind. Background Art
[0002] The motor circuit board of a venetian blind usually includes multiple electronic components, such as integrated circuits, resistors, capacitors, diodes, magnetic sensitive components, etc. These components are connected together through circuits to achieve the control function of the motor. The circuit board controls actions such as the start, stop, forward and reverse rotation of the motor by receiving external signals (such as remote control signals, switch signals, etc.), thereby driving the opening and closing of the venetian blind.
[0003] When assembling the circuit board, it is necessary to install the circuit board inside the support shell, and then install the support shell inside the steel pipe so that the assembly can be completed. The parts inside the steel pipe are first assembled into semi-finished products. Since there are many parts in the internal components, after the tolerances of each part are accumulated, there will be a large floating space in the distance between the first and last screw holes. When the assembled internal structure components are inserted into the steel pipe and the first screw is aligned and driven in, there will be a problem that the screw holes of the steel pipe and the internal plastic parts on the left side are not aligned, resulting in inability to assemble. Therefore, for the improvement of the existing support shell, it is particularly important to design a new type of support shell for the motor circuit board of a venetian blind to solve the above technical defects and improve the practicability of the overall support shell. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a support shell for a motor circuit board of a venetian blind. When a component contacts the main body of the support shell, it contacts the soft glue and squeezes the soft glue. When the soft glue receives an axial force, it will deform. When receiving a lateral force, the semi-circular soft glue will bend outward. According to the magnitude of the force, the component can be compressed into any required length to adapt to the different cumulative errors of each finished product. At the same time, there is a clearance fit between the steel pipe and the internal components. The soft glue that bends outward can contact the steel pipe, playing a role in having a support point between the entire internal component and the steel pipe at the central position, making the entire internal structure more stable, so as to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A support shell for a motor circuit board of a venetian blind, including a main body of the support shell. A PCBA board is arranged inside the main body of the support shell, and a connection groove is formed on the outer side of the main body of the support shell. Soft glue is arranged inside the connection groove. A steel pipe is arranged on the outer side of the main body of the support shell and on the outer side of the soft glue. Components are arranged at both ends of the steel pipe.
[0007] As a preferred solution of the present utility model, the internal structure size of the connection groove corresponds to the external structure size of the soft rubber. The soft rubber is connected to the main body of the support housing through the connection groove, and the outer diameter of the soft rubber is smaller than the outer diameter of the main body of the support housing.
[0008] As a preferred solution of the present utility model, the external structure size of the soft rubber corresponds to the internal structure size of the steel pipe. The main body of the support housing is connected to the steel pipe through the soft rubber.
[0009] As a preferred solution of the present utility model, the soft rubber is designed in a semi-circular structure, and the soft rubber is made of rubber material.
[0010] As a preferred solution of the present utility model, both groups of the components are connected to the PCBA board through the main body of the support housing, and the external structure size of the components corresponds to the internal structure size of the steel pipe.
[0011] As a preferred solution of the present utility model, first connection holes are provided at both ends of the steel pipe and near both ends of the two groups of components. Second connection holes are provided on the outer sides of the components. The internal structure size of the first connection holes corresponds to the internal structure size of the second connection holes.
[0012] As a preferred solution of the present utility model, screws are provided inside both ends of the steel pipe and within the two groups of first connection holes. The external structure size of the screws corresponds to the internal structure size of both the first connection holes and the second connection holes. The steel pipe is connected to the components through the screws.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] In the present utility model, through the design of the main body of the support housing, when the components come into contact with the main body of the support housing, they come into contact with the soft rubber and squeeze the soft rubber. When the soft rubber receives an axial force, it will deform. When it receives a lateral force, the semi-circular soft rubber will bend outward. According to the magnitude of the force, this part can be compressed into any required length to adapt to the different cumulative errors of each finished product. At the same time, the steel pipe and the internal components have a clearance fit. The soft rubber that bends outward can come into contact with the steel pipe, playing a role in having a support point between the entire internal components and the steel pipe at the central position, making the entire internal structure more stable.

[0020] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.
[0021] Embodiment:
[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0023] A support housing for a louver curtain motor circuit board, comprising a main body 1 of the support housing. The inside of the main body 1 of the support housing is provided with a PCBA board 2, and a connection groove 3 is opened on the outside of the main body 1 of the support housing. A soft glue 4 is arranged inside the connection groove 3. A steel pipe 5 is arranged on the outside of the main body 1 of the support housing and on the outside of the soft glue 4. Components 6 are arranged at both ends of the steel pipe 5.
[0024] Furthermore, the internal structure size of the connection groove 3 is designed to correspond to the external structure size of the soft glue 4. The soft glue 4 is connected to the main body 1 of the support housing through the connection groove 3, and the outer diameter of the soft glue 4 is smaller than the outer diameter of the main body 1 of the support housing. Connecting the soft glue 4 to the connection groove 3 enables the soft glue 4 to be connected to the main body 1 of the support housing.
[0025] Among them, the external structure size of the soft glue 4 is designed to correspond to the internal structure size of the steel pipe 5. The main body 1 of the support housing is connected to the steel pipe 5 through the soft glue 4. The soft glue 4 is designed in a semi-circular structure, and the soft glue 4 is made of rubber material. When the main body 1 of the support housing is connected to the steel pipe 5, the outwardly bent soft glue 4 can contact the steel pipe 5, providing a support point for the entire internal component at the center position with the steel pipe 5, making the entire internal structure more stable.
[0026] Furthermore, both sets of components 6 are connected to the PCBA board 2 through the support housing body 1, and the external structure size of the component 6 is designed to correspond to the internal structure size of the steel pipe 5. Connect the component 6 to the support housing body 1 so that the component 6 can be connected to the PCBA board 2 inside it, and then install the component 6 inside the steel pipe 5 to complete the assembly.
[0027] Furthermore, first connection holes 7 are provided at both ends of the steel pipe 5 and near both ends of the two sets of components 6, and second connection holes 8 are provided on the outer side of the component 6. The internal structure size of the first connection hole 7 is designed to correspond to the internal structure size of the second connection hole 8. Screws 9 are provided inside both ends of the steel pipe 5 and inside the two sets of first connection holes 7. The external structure size of the screw 9 corresponds to the internal structure sizes of both the first connection hole 7 and the second connection hole 8. The steel pipe 5 is connected to the component 6 through the screw 9. When the component 6 and the support housing body 1 are installed inside the steel pipe 5, the first connection hole 7 is docked with the second connection hole 8, and the screw 9 is installed inside the first connection hole 7 and the second connection hole 8, so that the component 6 can be installed inside the steel pipe 5, and thus the support block body can be installed inside the steel pipe 5, and therefore the PCBA board 2 can be installed inside the steel pipe 5.
[0028] In this embodiment, the implementation scenario is specifically as follows: during actual use, connect the component 6 to the support housing body 1, and then connect the component 6 and the support housing body 1 to the steel pipe 5. At the same time, when the component 6 comes into contact with the support housing body 1, it contacts the soft rubber 4 and squeezes the soft rubber 4. When the soft rubber 4 receives an axial force, it will deform. When it receives a lateral force, the semi-circular soft rubber 4 will bend outward. According to the magnitude of the force, this part can be compressed into any required length to adapt to the different cumulative errors of each finished product, so that the first connection hole 7 is docked with the second connection hole 8, and the screw 9 is installed inside the first connection hole 7 and the second connection hole 8, so that the component 6 can be installed inside the steel pipe 5, and thus the support block body can be installed inside the steel pipe 5, and therefore the PCBA board 2 can be installed inside the steel pipe 5. The steel pipe 5 and the internal components are in clearance fit, and the soft rubber 4 that bends outward can contact the steel pipe 5, playing a role in having a support point between the entire internal components and the steel pipe 5 at the central position, making the entire internal structure more stable. Compared with the existing support housing, the present utility model can improve the overall practicality of the support housing through the design.
