Image sensors are a type of linear image sensors, mainly used in scanners, fax machines and multifunction printers to scan flat images or documents into electronic formats for easy storage, display or transmission. Image sensors are usually equipped with a sensing module, and during the scanning movement, they maintain stable contact with the transparent glass plate above which the document to be scanned is placed, so as to achieve stable scanning of the document.

A Chinese patent with authorization announcement number CN204707174U discloses an image acquisition device, in which an image sensor module, supported by an elastic element, contacts a transparent plate through a rolling body. The rolling body has high precision, and the friction between the rolling body and the transparent plate is small, the change in depth of field is small, and the imaging distance is fixed, so that the image quality is high. Although the above-mentioned image acquisition device improves the image quality, when the above-mentioned image acquisition device is actually used, the image sensing module is generally installed with a module bracket to facilitate the movement of the image sensing module. However, the image sensing module cannot be accurately positioned and installed with the module bracket during installation, and repeated installation is required, thereby increasing the difficulty of installing the image sensor and not facilitating the rapid installation and use of the image sensing module.

To solve the above problems, an image sensing module is proposed in this application.

Detailed ways

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The utility model provides an image sensing module as shown in FIG1 , comprising:

A module bracket assembly 1, a symmetrically distributed side plate 11 is installed at the top of the module bracket assembly 1, a moving assembly 13 is installed at the bottom of the module bracket assembly 1, and a detachable sensing module body 12 is installed on the module bracket assembly 1; the structure and principle of the moving assembly 13 are prior art, and its specific sliding principle can be referred to the comparative document (the authorization announcement number is CN204707174U, and the patent name is image acquisition device), which will not be repeated here;

As can be seen from the above, when in use, the sensing module body 12 is installed on the module bracket assembly 1, and the sensing module body 12 is located between the two side panels 11, so as to increase the stability of the sensing module body 12 on the module bracket assembly 1, and the moving assembly 13 is installed on the track, so that the module bracket assembly 1 and the moving assembly 13 drive the sensing module body 12 to move, so as to perform document scanning operations.

Referring to FIGS. 1 to 4 , the positioning assembly 2 is used to accurately position the sensing module body 12 and the module bracket assembly 1. The positioning assembly 2 includes a counterweight rod 22 fixed to the bottom end of the sensing module body 12 and a mounting cavity 23 provided at the top end of the module bracket assembly 1. A clamping assembly 3 for limiting the counterweight rod 22 is installed in the mounting cavity 23. A connecting column 32 is also fixed in the mounting cavity 23, and one side of the connecting plate 31 is sleeved on the outside of the connecting column 32.

The clamping assembly 3 includes two connecting plates 31 hinged in the installation cavity 23 and symmetrically distributed, and a gravity column 21 fixed to the outside of the counterweight rod 22. A through groove for the counterweight rod 22 to move is formed between the two connecting plates 31. The two connecting plates 31 are provided with a limiting cavity 33 that cooperates with the gravity column 21 on the opposite sides. A stabilizing assembly that supports the connecting plates 31 is provided in the installation cavity 23.

Through the above technical solution:

When the image sensor is installed, it is installed between the sensing module body 12 and the module bracket assembly 1. At this time, the counterweight rod 22 is inserted into the installation cavity 23. Since the counterweight rod 22 is located in the installation cavity 23 and one end extends into the through groove, the through groove is used to guide the counterweight rod 22. However, the gravity column 21 is located in the limiting cavity 33 by the counterweight rod 22, so that the gravity in the limiting cavity 33 is increased, which is used to rotate and move the two connecting plates 31 along the outside of the connecting column 32 relative to each other, so that the limiting cavity 33 and the gravity column 21 are clamped, and the stability of the counterweight rod 22 in the through groove is increased, which can accurately position the sensing module body 12 during installation, solves the problem that the sensing module body 12 cannot be accurately positioned and installed with the module bracket assembly 1 during installation, and needs to be repeatedly installed many times, reduces the installation difficulty of the image sensor, and improves the rapid installation and use of the image sensing module, so that the sensing module body 12 can provide good scanning image quality.

Furthermore, the stabilizing component includes a stabilizing groove provided on the bottom wall of the mounting cavity 23 and an elastic support frame 34 installed at the connection between the two connecting plates 31, and the elastic support frame 34 is located in the stabilizing groove, and a telescopic column 35 is fixedly connected to the elastic support frame 34; based on this, the two connecting plates 31 are subjected to force and move relative to each other. At this time, when the connecting plates 31 are moving, the connection between the two connecting plates 31 and the elastic support frame 34 conflicts with each other, and the internal gravity of the connecting plates 31 increases, so that the outside of the elastic support frame 34 is subjected to external pressure. The elastic support frame 34 is compressed in the stabilizing groove under force, and the elastic force of the elastic support frame 34 itself converts the external pressure into elastic potential energy, so that it fits tightly with the connection between the two connecting plates 31, thereby increasing the stability of the two connecting plates 31.

In addition, referring to Figures 1 and 4, a connecting component 4 is also provided between the side panel 11 and the sensing module body 12, and the connecting component 4 includes a latch slot 43 provided at the top of the side panel 11 and a silicone gasket 42 connected to one side of the sensing module body 12, a latch column 41 is clamped in the latch slot 43, and a plug-in component is provided between the latch column 41 and the silicone gasket 42; the plug-in component includes a notch 45 provided on one side of the side panel 11 and a mounting block 44 fixed on one side of the silicone gasket 42, and the notch 45 is connected to the latch slot 43, and one side of the mounting block 44 extends into the notch 45 and is fixedly connected to one side of the latch column 41.

Through the above technical solution:

When in use, the sensing module body 12 is installed between the module bracket assembly 1, and the latch column 41 is inserted into the latch slot 43. The latch slot 43 and the latch column 41 are clamped and fixed. Since the latch column 41 drives the mounting block 44 to move synchronously during the movement of the latch column 41 along the latch slot 43, the mounting block 44 is inserted into the slot 45, which is used to install the silicone gasket 42 between the sensing module body 12 and the side plate 11, and one side of the silicone gasket 42 absorbs pressure and then deforms, so that the contact range between one side of the silicone gasket 42 and the sensing module body 12 is increased, further improving the stability of the sensing module body 12 located between the two side plates 11, and can provide a stable support effect for the sensing module body 12, preventing the sensing module body 12 from shaking between the module bracket assembly 1 after installation, further improving the stability of the sensing module body 12, and increasing the practicality of the image sensor, so that the sensing module body 12 can provide good scanning image quality.

Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein by equivalents.
