Description

Technical Field

[0001] The present invention relates to the technical field of scanning tools, in particular to a scanning pen. Background Art

[0002] Scanning pen is also called micro scanner or hand-scraping scanning pen. The so-called scanning pen is to scan the image, table or printed font directly into the pen for storage or directly transfer to the computer for storage, reading or editing and modification by aiming the scanning head of the scanning pen at the object to be scanned through scanning technology.

[0003] When the user uses the scanning pen, due to the user's usage habits, there is a second angle between the scanning pen and the scanned object when the scanning pen is tilted as a whole. When the user holds the scanning pen in a gesture-compliant state, the scanning pen will form another angle between the scanning pen and the scanned object. Different users will have different second angles when using the scanning pen, and the user can adjust the size of the second angle by adjusting the grip. However, the scanning head of the existing scanning pen is mostly fixed on the scanning pen, making it difficult for the user to adapt to the angle of the gesture and wrist when adjusting the angle between the scanning pen and the scanned object, resulting in a poor user experience when using the scanning pen.

[0066] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0067] In order to simplify the drawings, only the parts related to the present invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0068] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0069] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0070] In one embodiment, referring to the accompanying drawings, Figures 1 to 14 A scanning pen is described, in which a scanning head 2000 is rotatably set at one end of a pen body 1000, and a user adjusts the size of a first angle α by rotating his wrist, thereby satisfying the user's usage habits and improving the user's experience.

[0071] Specifically, see the attached drawings of the specification Figures 1 to 3 A scanning pen includes a pen body 1000 and a scanning head 2000. The pen body 1000 is provided with a accommodating cavity. The scanning head 2000 is hinged at one end of the pen body 1000 so that the scanning head 2000 and the pen body 1000 can rotate relative to each other.

[0072] It is understandable that during the scanning process, the user holds the scanning pen, the pen body 1000 has a holding posture, and the scanning head 2000 contacts the surface of the scanned object and moves relative to the scanned object to scan the scanned object. Accordingly, a first angle α is formed between the scanning head 2000 and the pen body 1000, and a second angle β is formed between the entire scanning pen and the scanned object.

[0073] In this embodiment, by rotatably setting the scanning head 2000 at one end of the pen body 1000, when the scanning pen is in use, the user can tilt the entire scanning pen by holding the pen body 1000 and thus adjust the size of the second angle β. Accordingly, the size of the first angle α can also be adjusted by relative rotation of the scanning head 2000 and the pen body 1000, so that the pen body 1000 rotates toward the direction close to the human body. Therefore, the user can hold the scanning pen according to his or her actual needs and adjust the first angle α to a suitable angle, so that the scanning pen can adapt to the angle requirements of the gesture and wrist, thereby improving the user experience and meeting the needs of ergonomics.

[0074] It is understandable that when in use, the user holds the pen body 1000 of the scanning pen, and contacts the scanning head 2000 with the surface of the scanned object, and drives the scanning head 2000 to move on the surface of the scanned object. In this process, the user can adjust the size of the first angle α by rotating the pen body 1000 relative to the scanning head 2000, so that the pen body 1000 reaches a suitable angle between the human body and the scanned object, adapting to the user's gestures and wrist angles, so that the user can use the scanning pen at a comfortable first angle α, thereby improving the user's experience. In addition, by rotatably setting the scanning head 2000 at one end of the pen body 1000, the user can make the scanning head 2000 fit the surface of the scanned object in the process of adjusting the first angle α, and will not separate from the scanned object, thereby ensuring the scanning effect.

[0075] In one embodiment, referring to the accompanying drawings, Figure 1 , Figure 6 , Figure 7 , the present embodiment further describes the scanning head 2000. The pen body 1000 is provided with a first opening at one end in the length direction, and the scanning head 2000 includes a fixed bracket 2100 and a camera module. The fixed bracket 2100 includes a first connecting member 2110, a first supporting member 2120 and a first fixed axis 2130. The first supporting member 2120 is provided with two respectively arranged at two opposite ends of the first supporting member 2120 and located on the same side of the first connecting member 2110, so that the fixed bracket 2100 is U-shaped. Accordingly, the two first supporting members 2120 form a scanning window, and a containing space is provided in the first connecting member 2110. The camera module is provided in the containing space and is directly opposite to the scanning window. The camera module scans the surface of the scanned object through the scanning window.

[0076] Correspondingly, a through hole matching the first fixed axis 2130 is provided on the pen body 1000, the fixing bracket 2100 is partially arranged in the first opening, and the first fixed axis 2130 penetrates into the through hole, so that the fixing bracket 2100 is rotatably arranged at the first opening of the pen body 1000.

[0077] It is understandable that a mounting plate may also be provided in the pen body 1000, and vias are provided on the mounting plate. The mounting plate is made of metal material and is fixed in the pen body 1000 by gluing or screws to improve the local strength of the scanning pen and to increase the service life.

[0078] In one embodiment, the first fixed axis 2130 is disposed on one of the two first supporting members 2120, so that the rotation center is located on one side of the scanning head 2000. When the user uses the scanning pen, the scanning head 2000 is driven to rotate by pushing the first supporting member 2120 on which the first fixed axis 2130 is not disposed, so that the scanning head 2000 performs unidirectional rotation.

[0079] Preferably, see the accompanying drawings of the specification Figure 7 A first extension portion 2140 is provided on one side of the first connecting member 2110, and the first extension portion 2140 is located between the two first supporting members 2120. The first fixed axis 2130 is located at one end of the first extension portion 2140 away from the first connecting member 2110, so that the scanning head 2000 can rotate in both directions, thereby improving the adjustment range of the first angle α.

[0080] See the attached drawings in the specification Figure 1 The pen body 1000 includes a first shell 1100 and a second shell 1200 , the first shell 1100 and the second shell 1200 are covered and connected to form a receiving cavity and a first opening, and a through hole is opened on the second shell 1200 .

[0081] Further, see the accompanying drawings of the specification Fig.14 , the present embodiment further describes the scanning head 2000, and a sliding protrusion 2111 is further provided on the scanning head 2000, and the sliding protrusion 2111 is located on the side of the first connecting member 2110 close to the first housing 1100, that is, on the side of the first connecting member 2110 away from the first extension portion 2140. Accordingly, the sliding protrusion 2111 is arc-shaped, and a sliding groove matching with the sliding protrusion 2111 is provided on the side of the first housing 1100 close to the scanning head 2000, so that the sliding protrusion 2111 is located in the sliding groove, and when the scanning head 2000 rotates relative to the pen body 1000 through the first fixed axis 2130, the sliding protrusion 2111 can move in the sliding groove. It can be understood that by simultaneously providing the first fixed axis 2130 and the sliding protrusion 2111 on the opposite sides of the scanning head 2000, the stability of the scanning head 2000 during rotation is improved.

[0082] In one embodiment, referring to the accompanying drawings, Figure 4 , Fig.10 , Fig.12 The scanning pen is further described in this embodiment. The scanning pen is also provided with an adjustment component 3000, which is arranged in the accommodation cavity of the pen body 1000 and is transmission-connected with the scanning head 2000 to maintain the size of the first angle α.

[0083] Furthermore, this embodiment provides a specific form of an adjustment component 3000. Specifically, see the attached Figures 4 to 8 The adjustment assembly 3000 includes a connecting plate 3100, a sliding plate 3200 and an adjusting plate 3300. The connecting plate 3100 is located above the first connecting member 2110, that is, the connecting plate 3100 is arranged on the side of the first connecting member 2110 away from the first supporting member 2120. A first baffle is arranged in the first housing 1100, and the first baffle is arranged perpendicular to the length direction of the first housing 1100. The connecting plate 3100 is connected and fixed to the first baffle. Accordingly, the sliding plate 3200 is located on the side of the connecting plate 3100 away from the second housing 1200, and two first limiting posts 3220 are also arranged on the sliding plate 3200. The first limiting posts 3220 are located on the side of the sliding plate 3200 away from the second housing 1200. The adjusting plate 3300 includes an adjusting plate body and a second extending portion 3310. The second extending portion 3310 is arranged on the side of the adjusting plate body close to the scanning head 2000. The adjusting plate body is provided with a first sliding hole 3330 matched with the first limiting column 3220 , and the first limiting column 3220 is arranged through the first sliding hole 3330 , so that the adjusting plate 3300 is movably arranged on the sliding plate 3200 .

[0084] Furthermore, two first bending portions 3230 are provided on the sliding plate 3200, and the two first bending portions 3230 are respectively arranged at both ends of the sliding plate 3200 in the length direction, and a first gear protrusion 3210 is provided at one end of the sliding plate 3200 close to the scanning head 2000, and a plurality of first gear grooves 2112 are provided on the side of the first connecting member 2110 close to the sliding plate 3200, and the first gear protrusion 3210 is located in one first gear groove 2112, and when the scanning head 2000 rotates relative to the pen body 1000, the first gear protrusion 3210 can be located in different first gear grooves 2112.

[0085] Correspondingly, the adjusting plate body is provided with second bending portions 3320 at both ends in the length direction, and the second bending portions 3320 are located above the first bending portions 3230, and a first elastic member 3340 is further provided between the first bending portion 3230 and the second bending portion 3320, and the first elastic member 3340 is in a compressed state. Figure 7Correspondingly, a second gear protrusion 3311 is provided at one end of the second extension portion 3310 away from the adjustment plate body, and a plurality of second gear grooves 2113 are provided on the sliding protrusion 2111, and the second gear protrusion 3311 is suitable for snap-fitting with the second gear groove 2113.

[0086] Furthermore, the first housing 1100 is also provided with a mounting groove, and the adjustment plate 3300 is arranged in the mounting groove so as to be movable up and down, and the mounting groove includes a first mounting groove and a second mounting groove, the first mounting groove is connected to the first sliding groove, and the second mounting groove is located above the sliding groove and the first mounting groove. Accordingly, the adjustment plate body is located in the second mounting groove, and the second extension portion 3310 is arranged in the first mounting groove.

[0087] When in use, the user can rotate the scanning head 2000 and the pen body 1000 to rotate relative to each other, so that the adjustment plate 3300 moves in the installation groove, the first gear protrusion 3210 and the current first gear groove 2112 are separated from each other, and the second gear protrusion 3311 and the current second gear groove 2113 are separated from each other. When the first angle α is rotated to a suitable first angle, the user stops rotating the scanning head 2000. Since the first elastic member 3340 is in a compressed state, the second gear protrusion 3311 is driven to move toward the direction close to the second gear groove 2113 under the action of the restoring force of the first elastic member 3340, so that the second gear protrusion 3311 and the second gear groove 2113 are engaged with each other. The first elastic member 3340 can be set as a spring or the like. Accordingly, under the action of the restoring force of the first elastic member 3340, the first gear protrusion 3210 and the first gear groove 2112 are driven to engage with each other, thereby fixing the size of the first angle α. It is understandable that the first gear protrusion 3210 is engaged with different first gear grooves 2112, and the second gear protrusion 3311 is engaged with different second gear grooves 2113, corresponding to different sizes of the first angle α. For example, each time the first gear protrusion 3210 rotates once and engages with the adjacent first gear groove 2112, it can be set that the scanning head 2000 rotates 5°, and rotating twice means that the scanning head 2000 rotates 10° to achieve gear adjustment. Of course, in actual production, the manufacturer can adjust the first gear groove 2112 and the second gear groove 2113 to achieve gear adjustment of different sizes and angles, which will not be described in detail here, and all are within the protection scope of the present invention.

[0088] In one embodiment, referring to the accompanying drawings, Fig.10 , Fig.11, this embodiment provides another way of adjusting the assembly 3000. A second baffle is disposed in the second housing 1200, and the second baffle is disposed perpendicular to the length direction of the second housing 1200. Specifically, the adjusting assembly 3000 includes a fixing plate 3400, a shift plate 3500 and a clamping member 3600, and the fixing plate 3400 is disposed above the first connecting member 2110, that is, the fixing plate 3400 is disposed on a side of the first connecting member 2110 away from the first supporting member 2120, and is connected and fixed to the second baffle.

[0089] Two second limiting posts 3410 are provided on one side of the fixed plate 3400 close to the second housing 1200. Correspondingly, a second sliding hole 3510 matching with the second limiting posts 3410 is provided on the shift plate 3500. The second limiting posts 3410 are arranged through the second sliding holes 3510, and the shift plate 3500 is then arranged on the fixed plate 3400, so that the shift plate 3500 and the fixed plate 3400 can move relative to each other. Moreover, the shift plate 3500 is provided with third bending portions 3540 at both ends in the length direction, and the fixed plate 3400 is provided with a sliding groove 3420 matching with the third bending portion 3540. When the shift plate 3500 is arranged on the fixed plate 3400, the third bending portion 3540 is located in the sliding groove 3420, and the shift plate 3500 moves relative to the fixed plate 3400 to drive the third bending portion 3540 to move in the sliding groove 3420.

[0090] Furthermore, a second elastic member 3520 in a compressed state is also provided in the sliding groove 3420, and the second elastic member 3520 is located between the third bending portion 3540 and the bottom wall of the sliding groove 3420. The second elastic member 3520 can be set as a spring, an elastic airbag or other elastic device. The side of the shift plate 3500 away from the first connecting member 2110 is arc-shaped, one end of the clamping member 3600 is fixed on the first connecting member 2110, and the other end is located above the arc-shaped side of the shift plate 3500, and under the action of the second elastic member 3520, it is pressed and contacted with the arc-shaped side of the shift plate 3500.

[0091] During use, when the scanning head 2000 and the pen body 1000 rotate relative to each other, the scanning head 2000 drives the clamping member 3600 to rotate, so that the end of the clamping member 3600 away from the scanning head 2000 moves along the shift plate 3500. When the first angle α rotates to a suitable angle, the arc-shaped side of the shift plate 3500 is pressed and contacted with the clamping member 3600 away from the first connecting member 2110 under the action of the second elastic member 3520, and the friction between the clamping member 3600 and the shift plate 3500 is used to fix the first angle α. Accordingly, in this embodiment, the user rotates the scanning head 2000 to adjust the first angle α, and the first angle α can be maintained at any angle (within a certain range).

[0092] It can be understood that in this embodiment, before using the scanning pen, the user can adjust the first angle α between the scanning head 2000 and the pen body 1000 to a suitable angle, and then contact the scanning head 2000 with the scanned object. Correspondingly, the user can also directly hold the pen body 1000 to contact the scanning head 2000 with the scanned object, and during use, constantly adjust the size of the first angle α to meet the angle requirements of the wrist. Of course, if the surface of the scanned object is undulating, when the user uses the scanning pen, the scanning head 2000 can also rotate with the undulations of the surface of the scanned object, so that the scanning head 2000 can be close to the surface of the scanned object to improve the scanning effect.

[0093] Furthermore, a plurality of third gear grooves 3530 are provided on one side of the arc-shaped shift plate 3500, and correspondingly, a third gear protrusion matching the third gear groove 3530 is provided on one end of the clamping member 3600 away from the first connecting member 2110. When the clamping member 3600 and the arc-shaped side of the shift plate 3500 are pressed and contacted with each other, the third gear protrusion is clamped in the third gear groove 3530, thereby achieving the angle fixation of the first angle α. In actual production applications, the manufacturer can adjust the third gear groove 3530 to achieve different gears of the scanning head 2000 rotation angle.

[0094] In one embodiment, referring to the accompanying drawings, Fig.12 , Fig.13 This embodiment provides another specific form of the adjustment assembly 3000. The adjustment assembly 3000 includes a first connecting rod 3810, a second connecting rod 3820, a mounting seat 3800 and a cam assembly 3700, wherein the mounting seat 3800 is disposed on the second housing 1200, and an arc-shaped slide rail is also disposed on the mounting seat 3800. One end of the second connecting rod 3820 is disposed on the first connecting member 2110, and a limiting column 3830 is disposed at one end of the second connecting rod 3820 away from the first connecting member 2110, and the limiting column 3830 is disposed in the arc-shaped slide rail.

[0095] Further, the cam assembly 3700 includes a first cam 3710, a second cam 3720, a second fixed shaft 3750, a mounting shell 3730 and a third elastic member 3740. The mounting shell 3730 is located on a side of the mounting seat 3800 away from the second housing 1200, and a receiving cavity is provided in the mounting shell 3730. The second fixed shaft 3750 is provided in the receiving cavity of the mounting shell 3730 and is connected and fixed to the mounting seat 3800. The first cam 3710, the second cam 3720 and the third elastic member 3740 are sequentially sleeved on the second fixed shaft 3750, the side of the first cam 3710 away from the second cam 3720 is in contact with the mounting seat 3800, one end of the third elastic member 3740 is in contact with the side of the second cam 3720 away from the first cam 3710, the other end of the third elastic member 3740 is in contact with the end of the mounting shell 3730 away from the mounting seat 3800, and the third elastic member 3740 is in a compressed state. Under the action of the third elastic member 3740, the first cam 3710 and the second cam 3720 are squeezed and contacted with each other.

[0096] Correspondingly, a second opening is provided on one side of the first cam 3710, and a third opening is provided on the mounting shell 3730. The second opening and the third opening are arranged opposite to each other and are connected to each other. One end of the first connecting rod 3810 passes through the third opening and the second opening and is sleeved on the second fixed shaft 3750. The other end of the first connecting rod 3810 is hinged on the limiting column 3830.

[0097] In this embodiment, when the scanning head 2000 and the pen body 1000 rotate relative to each other, the second connecting rod 3820 is driven to move, so that the limiting column 3830 moves in the arc-shaped slide rail. Correspondingly, the movement of the limiting column 3830 drives the first connecting rod 3810 to rotate, thereby driving the first cam 3710 and the second cam 3720 to rotate relative to each other. The third elastic member 3740 can be set as a spring or other elastic device. It can be understood that since the third elastic member 3740 is in a compressed state, when the scanning head 2000 rotates to a suitable angle, under the action of the restoring force of the third elastic member 3740, the first cam 3710 and the second cam 3720 are pressed and contacted with each other, so that the first cam 3710 and the second cam 3720 no longer rotate, thereby fixing the first angle α between the scanning head 2000 and the pen body 1000. In this way, the scanning head 2000 and the pen body 1000 can maintain the first angle α of any size (within a certain range).

[0098] Preferably, a friction member may be provided on the side where the first cam 3710 and the second cam 3720 are close to each other, so as to increase the friction between the first cam 3710 and the second cam 3720, and to increase the difficulty of the first cam 3710 and the second cam 3720 rotating after the scanning head 2000 rotates to a suitable angle. There are many types of friction members, such as rubber pads or aramid fiber washers, to achieve the purpose of increasing friction, which will not be described one by one here, and all are within the protection scope of the present invention.

[0099] Further, a plurality of fourth limiting grooves are arranged on the side of the first cam 3710 away from the mounting seat 3800, and the plurality of fourth limiting grooves are evenly distributed on the circumference. Accordingly, a plurality of fourth gear protrusions matching with the fourth gear grooves are arranged on the side of the second cam 3720 close to the first cam 3710. It can be understood that when the scanning head 2000 rotates to a suitable first angle α, the fourth limiting groove and the fourth limiting protrusion are engaged with each other, so that the first angle α between the scanning head 2000 and the pen body 1000 remains fixed. In addition, since the fourth limiting grooves are evenly arranged on the circumference, the fourth limiting protrusion can only be engaged in the fourth limiting groove, so that the first angle α is adjusted to a gear adjustment. For example, each fourth gear groove indicates that the scanning head 2000 rotates 5°, so that the rotation angle of the scanning head 2000 is 5°, 10°, 15°, etc.

[0100] In one embodiment, the scanning pen in this embodiment further includes a pressure sensing module of a circuit board, the circuit board is arranged in the pen body 1000, the pressure sensing module is arranged on the fixed bracket 2100, and the pressure sensing module is communicatively connected with the circuit board. It can be understood that when the user puts the scanning head 2000 on the object to be scanned, the pressure sensing module can sense the pressure information received by the fixed bracket 2100, and transmit the pressure information to the circuit board, and the circuit board controls the camera module to start the scanning function according to the pressure information to scan the object to be scanned.

[0101] Further, see the accompanying drawings of the specification Figure 1 The first roller 2213 and the second roller 2214 are disposed at one end of the fixed bracket 2100 away from the pen body 1000. Correspondingly, the first roller 2213 and the second roller 2214 are respectively disposed at the ends of the two first supporting members 2120. The first roller 2213 and the second roller 2214 are disposed to contact the surface of the scanned object and roll on the surface of the scanned object, thereby enabling the camera module to scan the scanned object and reducing the friction between the scanning head 2000 and the scanned object.

[0102] In addition, the end of the fixed bracket 2100 away from the pen body 1000 can also be set to a smooth curved surface, which can contact the surface of the scanned object through the smooth curved surface, and can also reduce the friction between the scanning head 2000 and the scanned object when moving.

[0103] In one embodiment, referring to the accompanying drawings, Figure 4 , Figure 7 , this embodiment further describes the scanning head 2000. Specifically, the scanning head 2000 also includes a cover shell 2300, the cover shell 2300 includes a second connecting member and a second supporting member, the second supporting member is provided in two, the two second supporting members are provided at opposite ends of the second connecting member, and the second connecting member is located between the two first supporting members 2120, and the two second supporting members are respectively mounted on the two first supporting members 2120.

[0104] Correspondingly, a fourth opening is provided on the second connecting member, the fourth opening is directly opposite to the camera module, a scanning window is provided, and a light-transmitting glass 2310 is provided on the fourth opening.
