With the advancement of software and hardware, scanners have become one of the basic equipment for many computer users. It can scan text or image data such as documents, magazines, books, pictures, etc. into the computer and process them. Among all kinds of scanners, the flatbed scanner is the most commonly used one. In the flatbed scanner, the scanning module is installed under a transparent platform in a way that can be pulled back and forth to scan documents placed on the transparent platform. . Moreover, the scanning module itself has no power, so it needs transmission mechanisms such as servo motors, gears, belts, etc. to drive it. When wanting to use a flat-bed scanner to scan a document, the document must be placed on the transparent platform, and then the document cover is covered to press the document flat against the transparent platform, and then scanned.

The advantage of this design is that it is very easy to assemble, and there is no problem of loosening or damage.

However, this design also has its disadvantages, that is, during a shock test, one side of the glass of the light-transmitting plate is often broken due to the forward collision of the light-transmitting plate.

Detailed ways

FIG. 1 and FIG. 2 are a three-dimensional schematic diagram and a three-dimensional exploded view of the optical scanner 100 and its shock absorbing structure of the present invention, respectively.

As shown in Figures 1 and 2, the main body 110 of the optical scanner 100 includes an upper housing 112 and a lower housing 114, and the transparent plate 120 is directly arranged and fixed on the upper housing 112, and one side thereof is inserted into the clip. Hold in an open slot 1141 of the lower housing 114 .

The upper case 112 is also fixed on the lower case 114 , and clamps and fixes the transparent plate 120 between the upper case 112 and the lower case 114 . In this way, the light-transmitting plate 30 has become an important supporting point in the structure, and the upper casing 112 has become an auxiliary reinforcing structure.

In order to prevent the side 122 of the light-transmitting plate 120 inserted into the opening groove 1141 from being broken due to collision during the vibration test, the utility model is arranged in the opening groove 1141 of the lower housing 114 with multiple (3 in this embodiment) 1) The elastic structure group 200, such as elastic material such as rubber, extends from the surface of the lower housing 114 toward the light-transmitting plate, and abuts against one side 122 of the light-transmitting plate 120, and uses the elasticity of its own material as a buffer, A shock-absorbing effect on the light-transmitting plate 120 is achieved.

Referring next to FIG. 3 , it shows a plan view of the relative position of the light-transmitting plate 120 and the elastic structure group 200. The elastic structure group 200 is in contact with the side 122 of the light-transmitting plate 120 at one end of the extending direction, and each elastic structure group 200 Each has a plurality (nine in this embodiment) of elongated (rectangular) elastic structures 210 , but the lengths of these elastic structures 210 are not all the same.

As shown in FIG. 4 , the length of the elastic structures 210 in this embodiment varies regularly, being the longest in the center and tapered symmetrically on both sides, so that the appearance of each elastic structure group 200 is roughly a mountain shape.

In this way, when the vibration drop test is performed, the light-transmitting plate 120 contacts the side 122 of the elastic structure group 200 through the multi-stage (length) structure of the elastic structure group 200, and each elastic structure group 200 will be compressed first. The longer elastic structures 210 contact and compress the subsequent shorter elastic structures 210 one by one in order to form a multi-stage buffering function.

That is to say, the plurality of elastic structure groups 200 of the present invention can utilize the elasticity of its own material and its multi-stage structure to absorb the collision force of the light-transmitting plate 120 in sections to achieve a better cushioning effect.

In addition, as shown in FIG. 5 , for the mountain-shaped elastic structure group 200 , the lengths of the elastic structures 210 on both sides of the elastic structure group 210 can be gradually shortened in a staggered left and right manner.

The elastic structure 210 is used to achieve the effect of segmented cushioning. That is to say, the shape of the elastic structure group 200 is not limited to the aforementioned mountain shape, trapezoid shape or wave shape, as long as it has the effect of being able to contact the light-transmitting plate 120 in sections and provide cushioning. That is to say, as long as the lengths of the elastic structures are not exactly the same and they are side by side with each other, they can have the effect of end cushioning, and the appearance of the overall elastic structure group can also be irregular.

Moreover, the shape of the elastic structure 210 is not limited to the elongated shape (rectangular shape) of this embodiment, and can also be various polygonal shapes such as a triangle as shown in FIG. 7 , as long as it can achieve a segmented cushioning effect . However, the buffer structure of the present invention should not be limited to the application between the light-transmitting plate and the casing of the optical scanner, as long as there is a joint between two hard objects, if there is a risk of vibration, it can be used in one of them. This elastic structure group is configured on the surface of the body to form a segmented buffer to achieve protection against collisions.
