Description

Technical Field

[0001] This utility model relates to the field of photocopying equipment technology, and in particular to a scanning component and scanning device. Background Technology

[0002] Scanning equipment typically includes an image scanning unit, which is driven by a drive assembly to move and scan an object placed on a glass panel to obtain an electronic image of the object. During scanning, due to the uneven surface of the glass panel, the scanning unit can float vertically to ensure scan quality. Therefore, a clearance is required between the scanning unit and the side wall of the housing on which it is mounted. However, when the drive assembly moves the scanning unit, the gap between the scanning unit and the housing, and the movement of the scanning unit to adapt to the flatness of the glass panel, results in inconsistent movement speeds between the scanning unit and the housing. This causes the scanning unit to shift and wobble, affecting the scanning effect. Utility Model Content

Because the elastic wall elastically abuts against the side wall of the mounting groove, the scanning assembly and the housing can maintain elastic contact via the elastic arm, ensuring that the position of the scanning device relative to the housing remains unchanged. Simultaneously, enabling the scanning device to move relative to the housing along its height direction effectively prevents discrepancies in the movement speeds of the scanning device and the housing, improving the reliability of the scanning assembly and enhancing scanning quality and effect.

[0042] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0043] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, inside, outside, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0044] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0045] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0046] Currently, scanning equipment typically includes an image scanning device. A drive assembly moves the image scanning device to scan objects placed on a glass panel, obtaining an electronic image of the object. During scanning, due to the uneven surface of the glass panel, the scanning device can float vertically to ensure scanning quality. Therefore, a clearance is required between the scanning device and the side wall of the housing on which it is mounted. However, when the drive assembly moves the scanning device, the gap between the scanning device and the housing, and the movement of the scanning device to adapt to the flatness of the glass panel, results in inconsistent movement speeds between the two, causing the scanning device to shift and wobble, affecting the scanning effect. In related technologies, an elastic plate is provided on the side wall of the housing, which elastically abuts against the scanning device to ensure a constant relative position between the scanning device and the housing. However, due to the trend towards lightweight scanning devices, the height of the scanning devices is becoming smaller, resulting in a corresponding decrease in the height of the elastic plate. This leads to insufficient elasticity of the elastic plate, failing to guarantee that the scanning device and the housing maintain elastic contact at all times, causing the scanning device to shift and wobble, thus affecting the scanning effect.

[0047] Therefore, some embodiments of this utility model propose a scanning component and a scanning device, as detailed below. Figures 1 to 10 The scanning component 1000 and the scanning device 2000 are described.

[0048] Reference Figure 1 , Figure 2 and Figure 4 In a first aspect of this invention, a scanning assembly is provided, including an image acquisition assembly 100 and a driving assembly 200. The image acquisition assembly 100 includes a housing 110, a scanning device 120, and a friction element 130. The housing 110 has a mounting groove 111, the opening of which faces upwards along the height direction of the housing 110. The scanning device 120 is mounted in the mounting groove 111 and is movably connected to the housing 110. A scanning panel 521 is provided above the scanning assembly 100, and the scanning device 120 contacts and slides on the scanning panel 521. The driving assembly 200 is connected to the housing 110 and drives the image acquisition assembly 100 to move, causing the scanning device 120 to slide along the scanning panel 521 to acquire images of objects on the scanning panel 521.

[0049] Understandably, because the scanning device 120 is spaced apart from the side wall of the mounting groove 111, and the scanning device 120 is movably connected to the housing 110, the scanning device 120 can move relative to the housing 110, thereby allowing the scanning device 120 to adjust its movement according to the flatness of the scanning panel 521. The friction member 130 is connected to the upper side of the scanning device 120, and the friction member 130 can drive the scanning device 120 to move along the height direction of the housing 110 within the mounting groove 111, ensuring scanning quality by allowing the scanning device 120 to move along the height direction of the housing 110 according to the flatness of the scanning panel 521.

[0050] Reference Figure 5 In some embodiments of this utility model, an elastic element 140 is provided between the bottom wall of the mounting groove 111 and the scanning device 120. The elastic element 140 can drive the scanning device 120 to move along the height direction of the housing 110, that is, the elastic element 140 makes the scanning device 120 always tend to move towards the scanning panel 521 along the height direction of the housing 110. When the driving component 200 drives the image acquisition component 100 to move, the friction element 130 abuts against the scanning panel 521 and is slidably connected to the scanning panel 521. By providing the elastic element 140 and the friction element 130 at both ends of the scanning device 120 along its height direction, and with the friction element 130 abutting against the scanning panel 521, when the driving component 200 drives the image acquisition component 100 to move, the friction element 130 will move up and down due to the unevenness of the scanning panel 521, thereby driving the scanning device 120 to move up and down. This allows the scanning device 120 to float and adjust up and down according to the flatness of the scanning panel 521, ensuring scanning quality and scanning effect.

[0051] It is understood that the elastic element 140 is a spring. The elastic element 140 can also be a bellows, rubber block, or other elastic structure, which can be selected according to the actual application, and this application does not limit it.

[0052] Reference Figure 6 and Figure 7 In some embodiments of this utility model, the friction member 130 has a raised rib 133 on the side facing the scanning panel 521. The raised rib 133 is attached to the scanning panel 521 and slidably connected to the scanning panel 521. By setting the raised rib 133 to be attached to the scanning panel 521, and when the driving device driving assembly 200 drives the image acquisition assembly 100 to move, the raised rib 133 causes the friction member 130 to move up and down due to the unevenness of the scanning panel 521, thereby driving the scanning device 120 to move up and down. By having the raised rib 133 attached to the scanning panel 521, the contact between the friction member 130 and the scanning panel 521 is more stable, thereby making the scanning device 120 more stable relative to the scanning panel 521.

[0053] Reference Figure 4 and Figure 5 In some embodiments of this utility model, the friction member 130 is provided with an elastic wall, which elastically abuts against the side wall of the mounting groove 111. Since the driving assembly 200 drives the image acquisition assembly 100 to move along the connection direction between the elastic wall and the side wall of the mounting groove 111, when the driving assembly 200 drives the image acquisition assembly 100 to scan, the scanning device 120 and the housing 110 can maintain elastic contact through the elastic wall, ensuring that the position of the scanning device 120 relative to the housing 110 remains unchanged. Simultaneously, the scanning device 120 can move up and down along the height direction of the housing 110 according to the flatness of the scanning panel 521, ensuring the reliability of the scanning assembly 1000 and effectively reducing the risk of inconsistent movement speeds between the scanning device 120 and the housing 110, thus ensuring scanning quality and improving scanning effect.

[0054] Reference Figure 2 In this embodiment of the invention, two friction elements 130 are provided, and the two friction elements 130 are respectively located at both ends of the scanning device 120 along its length direction. By having the two friction elements 130 respectively located at both ends of the scanning device 120, the stress distribution on the scanning device 120 is more uniform, which improves the stability of the scanning device 120, reduces the risk of the scanning device 120 shaking relative to the housing 110, and thus improves the scanning quality and scanning effect.

[0055] Reference Figure 3 and Figure 6 In some embodiments of this utility model, the elastic wall includes a connecting section 1311 and an abutting section 1312. The connecting section 1311 protrudes to form a sidewall of the friction member 130, that is, the connecting section 1311 extends outward along the sidewall of the friction member 130 in the horizontal plane. The abutting section 1312 is connected to the connecting section 1311 and extends downward along the height direction of the housing 110, that is, along the height direction of the housing 110, the abutting section 1312 extends downward from the end of the connecting section 1311 away from the sidewall of the friction member 130. The abutting section 1312 abuts against the sidewall of the mounting groove 111. By setting the connecting section 1311 and the abutting section 1312 in the elastic wall, the structural stability of the elastic wall is improved, the elastic performance of the elastic wall is enhanced, the reliability of the elastic wall is improved, and the elastic abutment between the scanning device 120 and the housing 110 is maintained.

[0056] Reference Figure 6In some embodiments of this utility model, the end face of the abutment section 1312 facing the side wall of the mounting groove 111 is provided with a protrusion 1313. The protrusion 1313 is provided with an arc surface 1314, and the protrusion 1313 abuts against the side wall of the mounting groove 111 through the arc surface 1314. Because the protrusion 1313 abuts against the side wall of the mounting groove 111, the elastic performance of the abutment section 1312 is improved. Because the protrusion 1313 is provided with an arc surface 1314 abutting against the side wall of the mounting groove 111, the contact area between the protrusion 1313 and the side wall of the mounting groove 111 is increased, the stress distribution on the surface of the protrusion 1313 is optimized, and at the same time, the flexibility of the protrusion 1313 elastically abutting against the side wall of the mounting groove 111 is improved, facilitating the stability of the scanning device 120 moving up and down along the height direction of the housing 110, and improving the reliability of the elastic wall.

[0057] Reference Figure 4 and Figure 7 In some embodiments of this utility model, the top of the scanning device 120 is provided with a positioning hole 121, and the lower side of the friction member 130 protrudes to form a positioning post 132 corresponding to the positioning hole 121. The positioning post 132 passes through the positioning hole 121 so that the friction member 130 is positioned and installed on the scanning device 120, which facilitates the installation and positioning of the friction member 130.

[0058] It is understood that two positioning holes 121 can be provided, with the two positioning holes 121 arranged at intervals along the width direction of the scanning device 120. Two positioning posts 132 are provided, with each positioning post 132 corresponding to one of the two positioning holes 121. By providing two positioning posts 132 and two positioning holes 121, the stress distribution between the friction element 130 and the scanning device 120 is optimized, and the stability of the connection between the friction element 130 and the scanning device 120 is improved.

[0059] It is understood that there can be two or more positioning holes 121 and positioning posts 132 respectively. The specific number and distribution of positioning holes 121 and positioning posts 132 can be selected according to the actual application, and this application does not limit them here.

[0060] Reference Figure 5 and Figure 6In some embodiments of this utility model, the friction member 130 and the scanning device 120 are connected by a first snap-fit ​​structure 300. The first snap-fit ​​structure 300 includes a first snap 310 and a first latch 320. The first snap 310 is disposed on the friction member 130, and the first latch 320 is provided with the scanning device 120. The first latch 320 extends outward from the side wall of the scanning device 120. The first snap 310 extends downward along the height direction of the friction member 130, and a first hook 311 is formed by the side wall of the first snap 310 protruding towards the end face of the first latch 320. The end face of the first hook 311 engages with the first latch 320, so that the first snap 310 engages with the first latch 320, thereby connecting the friction member 130 to the scanning device 120 and reducing the risk of the friction member 130 detaching from the scanning device 120 along its height direction.

[0061] It is understood that the first latch 320 may also extend inward from the side wall of the scanning device 120 to form a groove, and the first hook 311 of the first latch 310 is fastened to the groove wall of the first latch 320. The specific fastening structure of the first latch 320 and the first latch 310 can be selected according to the actual application, and this application does not limit it here.

[0062] It is understood that one of the first latch 310 and the first latching position 320 is located on the friction member 130, and the other of the first latch 310 and the first latching position 320 is located on the scanning device 120. That is, the first latch 310 can be located on the friction member 130 and the first latching position 320 can be located on the scanning device 120, or the first latch 310 can be located on the scanning device 120 and the first latching position 320 can be located on the friction member 130. The choice can be made according to the actual application, and this application does not limit it.

[0063] Reference Figure 3 , Figure 5 and Figure 8In some embodiments of this utility model, the housing 110 and the scanning device 120 are connected by a second snap-fit ​​structure 400, which includes a second snap 410 and a second latch 420. The second snap 410 is disposed on the housing 110, and the second latch 420 is disposed on the scanning device 120. The second snap 410 extends upward from the bottom wall of the mounting groove 111 along the height direction of the housing 110, that is, the second snap 410 protrudes to form a connection with the bottom wall of the mounting groove 111. A second hook is provided at the end of the second snap 410, which protrudes from the side wall of the second snap 410 toward the second latch 420. The friction element 130 has a clearance groove 134 on its side wall, which exposes the end face of the scanning device 120 near the friction element 130. The end face of the clearance groove 134 and the corresponding position of the scanning device 120 form a second latch 420. The end face of the second hook can abut against the end face of the scanning device 120 below the clearance groove 134, so that the second latch 410 can be fastened in the second latch 420, thereby limiting the height of the scanning device 120 relative to the housing 110 and reducing the risk of the scanning device 120 detaching from the housing 110 along the height direction of the housing 110. Since the end face of the second hook can abut against the end face of the scanning device 120 below the clearance groove 134, there is no need to set up another structure on the scanning device 120 to fasten the second hook, which facilitates the installation of the scanning device 120, reduces the processing difficulty of the scanning device 120, and saves manufacturing costs.

[0064] It is understood that the scanning device 120 has a first state and a second state. When the scanning component 1000 is not installed below the scanning panel 521, that is, when the friction component is not in contact with the scanning panel 521, the scanning device 120 is in the second state. When the scanning component 1000 is installed below the scanning panel 521, that is, when the scanning panel 521 presses against the friction component 130, thereby compressing the elastic component 140, the scanning device 120 is in the second state. When the scanning device 120 is in the second state, the second latch 410 is engaged with the second latch position 420, reducing the risk of the scanning device 120 dislodging from the housing 110 and improving the structural stability of the image acquisition component 100. When the scanning device 120 is in the second state, because the scanning panel 521 presses against the friction component 130, thereby compressing the elastic component 140, the scanning device 120 moves downward along the height direction of the housing 110, at which time the second latch 410 disengages from the second latch position 420. By switching between the first and second states, the scanning device 120 ensures the structural stability and reliability of the image acquisition component 100.

[0065] Understandably, when the scanning device 120 is in the first state, the elastic wall elastically abuts against the side wall of the mounting groove 111. This keeps the position of the scanning device 120 relative to the housing 110 fixed, reducing the risk of damage from the scanning device 120 impacting the housing 110. When the scanning device 120 is in the second state, the elastic wall elastically abuts against the side wall of the mounting groove 111, reducing the risk of the scanning device 120 shaking relative to the housing 110 when the drive device moves the image acquisition component 100, thus ensuring scanning quality and effect. In other words, regardless of whether the scanning device 120 is in the first or second state, the elastic wall always maintains elastic abutment against the side wall of the mounting groove 111, improving the structural stability and reliability of the scanning component 1000.

[0066] It is understood that the second latch 410 is provided on the housing 110, and the second latching position 420 is provided on the scanning device 120. The second latching position 420 may also be formed by protruding from the side wall of the scanning device 120, with the end face of the second hook engaging with the side wall of the scanning device 120. Alternatively, a groove may be formed inward on the side wall of the scanning device 120, with the second hook engaging with the inner wall of the groove. The specific engaging structure of the second latch 410 and the second hook can be selected according to the actual application, and this application does not limit it here.

[0067] It is understood that one of the second latch 410 and the second latch position 420 is disposed in the housing 110, and the other of the second latch 410 and the second latch position 420 is disposed in the scanning device 120. That is, the second latch 410 can be disposed in the housing 110 and the second latch position 420 can be disposed in the scanning device 120, or the second latch 410 can be disposed in the scanning device 120 and the second latch position 420 can be disposed in the housing 110. The choice can be made according to the actual application, and this application does not limit it.

[0068] Reference Figure 9 and Figure 10 The present invention also provides a scanning device, including a housing 500 and a scanning component 1000 as described in the above embodiment. The housing 500 has a cavity 510 inside, the scanning component 1000 is disposed in the cavity 510, and the driving component 200 is used to drive the image acquisition component 100 to move along the length direction of the housing 500.

[0069] Reference Figure 9 and Figure 10In some embodiments of this utility model, the housing 110 includes an upper cover 520 and a lower cover 530, which together form a cavity 510. A transparent scanning panel 521 is disposed on the upper cover 520. The friction member 130 is provided with a rib 133, which is located at one end of the friction member 130 facing the upper cover 520, i.e., the rib 133 is located on the side of the friction member 130 facing the scanning panel 521. The rib 133 is attached to the scanning panel 521 and is slidably connected to the scanning panel 521.

[0070] Since the scanning device 2000 adopts all the technical solutions of the scanning component 1000 of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
