Description

Technical Field

[0001] The invention relates to the field of filter switches, and in particular to a switching signal feedback structure of a filter switch and a camera device. Background Art

[0002] The filter switch structure in the prior art uses a swing needle to drive the filter to switch left or right. The controller from the back end gives a switching signal to the switch, and the electronic signal generates a magnetic field through the driving coil, thereby generating an attraction and repulsion effect with the rotating magnet, causing the rotating magnet and the bonded swing rod to swing, thereby driving the filter switch to switch left or right. This is the type of structure that all switches currently on the market have.

[0003] However, due to the size and tolerance of the components, or component problems during assembly, the product structure may cause the switch to not switch or not switch into place after receiving the signal. However, the back-end controller does not know whether to switch or whether it has switched into place.

[0004] At present, the manufacturers of filter switches on the market generally only confirm whether the switch is working properly by visual inspection or through images. However, if the switch function is judged by images, it can only be confirmed by visual inspection after the image output. After the terminal product is assembled, it can only be checked by visual inspection whether the filter switch is switching normally. If it is not normal, there is no smart improvement, such as sending a signal again to let the switch switch switch again. At present, security products only send a signal once when controlling the switch. That is to say, the IC that sends the signal inside the monitor will only send a signal once when the switch needs to switch. The IC believes that the switch is very obedient and will definitely switch and switch in place. However, this is not the case. Any electronic product will have a failure rate. There is only a high or low rate, but it is impossible to have zero error. The key point is that there is no mechanism inside the structure of the switch to send a message to the control IC to let the IC know that the switch has not been switched or has not been switched in place. Therefore, even if the control IC at the end has many functions, it cannot be implemented. Summary of the invention

Specific embodiments

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways defined and covered by the claims.

[0021] The present invention utilizes the original switch structure and additionally designs a judgment structure to facilitate feedback of a signal to the backend control circuit, enabling the control circuit to determine whether the switch has switched and switched in place.

[0022] In one aspect of the present invention, a switching signal feedback structure for a filter switch is provided, including: a rotatable swing rod 1, a conductive disk 2, and a relatively fixed flexible circuit board 3. The flexible circuit board 3 is provided with a signal line 4 and at least one switching-in-place feedback line 5. The conductive disk 2 is fixedly installed on the swing rod 1, and the conductive disk 2 is provided with a first contact 6 and a second contact 7 that are electrically connected to each other. Only when the swing rod 1 switches in place, the signal line 4 is in electrical contact with the first contact 6, and one of the switching-in-place feedback lines 5 is in contact with the first contact 6. Preferably, the flexible circuit board 3 is further provided with a switching signal line 13 for transmitting a control signal used to generate a magnetic field in the coil of the filter switch in the prior art. The principle is the same as that in the prior art and will not be elaborated here.

[0023] In this way, when the control signal from the switching signal line 13 causes the swing rod 1 to rotate, the conductive disk 2 on the swing rod 1 also rotates accordingly. As a result, the positions of the first contact 6 and the second contact 7 also change. During the rotation process, the flexible circuit board 3 remains fixed in position, and the positions of the first contact 6 and the second contact 7 change. When the switching signal causes the swing rod 1 to reach a predetermined switching position, the signal line 4 makes conductive contact with the first contact 6, and one of the switching-in-place feedback lines 5 contacts the first contact 6, so that the signal sent out in the signal line 4 can be transmitted to one of the switching-in-place feedback lines 5 through the conductive disk 2, enabling an external control device connected to the flexible circuit board to detect a corresponding switching-in-place signal from this switching-in-place feedback line 5. As Figure 3 shown, if no switching-in-place signal is detected, it indicates that the swing rod is not in place and the switching is not in place.

[0024] Due to the adoption of the above technical solution, the present invention can enable the external controller at the back end to accurately know whether the switching is in place, and there is no need to make a judgment based on the image anymore, having the characteristics of simple structure and low cost.

[0025] Preferably, two fixing columns 8 are formed on the swing rod 1, and through holes 9 for the fixing columns 8 to pass through are provided on the conductive disk 2.

[0026] Preferably, one signal line 4 and two switching-in-place feedback lines 5 are provided on the flexible circuit board 3, and the signal line 4 is located between the two switching-in-place feedback lines 5.

[0027] Preferably, an arc-shaped conductive wire 10 is provided on the flexible circuit board 3, one end of the arc-shaped conductive wire 10 is conductively connected to the signal line 4, and the other end contacts or disconnects from the first contact 6.

[0028] Preferably, a straight-shaped conductive wire 11 is provided on the flexible circuit board 3, the other end of the arc-shaped conductive wire 10 is electrically connected to the middle of the straight-shaped conductive wire 11, and two contact points 12 for making conductive contact with the first contact 6 are respectively formed at both ends of the straight-shaped conductive wire 11.

[0029] The present invention also provides a camera device, including the switching signal feedback structure of the above-mentioned filter switcher.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
