This invention discloses a handwritten signature device and terminal. The writing device includes a housing disposed on the top of a workbench. A first support member is disposed at the bottom of the housing, and a second support member is disposed on the top of the workbench, which slides in cooperation with the first support member. A stop unit is disposed between the first support member and the housing. A limiting unit that cooperates with the first support member is disposed on the second support member, and a driving unit is disposed between the first and second support members. When the housing rotates to a vertical position, the limiting unit releases its restriction on the first support member. Through the cooperation of the limiting unit and the driving unit, when the housing rotates to the side of the glass panel and is in a vertical position, the self-locking effect is achieved by the gravity of the signature terminal, so that the housing and the signature terminal cannot rotate relative to the glass panel. This not only stores the signature terminal but also prevents dust from falling onto the screen of the signature terminal.

Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and in particular to a handwritten signature device and terminal. Background Technology

[0002] In daily life and work, many documents, orders, agreements, and contracts need to be signed in order to be legally authenticated, approved, and effective. Currently, electronic signatures are being gradually implemented in places requiring signatures, such as bank and telecommunications branches, and the signing devices used are mostly handwritten signature pads.

[0003] Chinese patent CN214376399U discloses a dual-touch electronic signature screen with photo-taking capability, comprising a housing and an electromagnetic pen. A connector is connected to the top of the housing, and a camera is movably connected to the top of the connector via a pin. An electromagnetic screen, consisting of a capacitive touchscreen and an electromagnetic touchscreen, is mounted on the surface of the housing. The electromagnetic screen and the electromagnetic pen are connected wirelessly. A control circuit board is located inside the housing and is electrically connected to the electromagnetic screen. A USB port is located on one side of the top surface of the housing, and a stylus holder with a pen cord loop is located on one side of the stylus holder.

[0031] like Figure 1-4 As shown, a signature handwriting device includes a housing 3 placed on top of a workbench 31 and a signature terminal disposed inside the housing 3. The signature terminal is a handwriting screen 2 and a stylus used in conjunction with it (not shown in the figure). A glass panel 1 is disposed on one side of the top of the workbench 31, and the housing 3 and the signature terminal are disposed between the workbench 31 and the glass panel 1.

[0032] Furthermore, a support adjustment assembly is provided between the bottom of the outer shell 3 and the worktable 31 to adjust the angle of the outer shell 3 at the top of the worktable 31, thereby facilitating the operator's use. Specifically, the adjustment support assembly includes a first support member connected to the bottom surface of the outer shell 3 and a second support member connected to the worktable 31. The first support member and the second support member are slidably engaged, and a stop unit is provided between the first support member and the outer shell 3. In actual use, the connection relationship between the first support member and the outer shell 3 is controlled by controlling the stop unit. When it is necessary to adjust the angle of the signing terminal at the top of the worktable 31, the stop unit can be controlled to remove the limit between the outer shell 3 and the first support member, thereby maintaining the stability of the signing terminal after adjustment.

[0033] Furthermore, a limiting unit that cooperates with the first support is provided on the second support. By adjusting the limiting unit to extend to the outside of the second support, the first support can be limited, thereby preventing the first support from sliding downward relative to the second support. In addition, a driving unit is provided between the first and second support, so that when the outer shell 3 drives the first and second support to rotate to a vertical position, the first support slides downward relative to the second support, and the driving unit drives the second support to rotate, thereby changing the rotation direction of the second support.

[0034] like Figure 1 , 4 As shown in Figure -10, the first support member includes a first connecting rod 11 hinged to the outer shell 3 and a first connecting shaft 12 integrally formed with the first connecting rod 11. A sleeve 13 is fixedly connected to the end of the first connecting shaft 12 away from the outer shell 3. The second support member includes a second connecting rod 10 connected to the workbench 31 and a second connecting shaft 14 integrally formed with the second connecting rod 10. Specifically, a base 6 is rotatably connected to the top of the workbench 31. Second vertical plates 7 are fixedly provided on both sides of the top of the base 6. A pin 8 is fixedly connected between the two second vertical plates 7. The pin 8 passes through one end of the second connecting rod 10 and is rotatably connected to it. In use, the pin 8 is parallel to the glass panel 1, so that the outer shell 3 can rotate relative to the glass panel 1 with the pin 8 as the center line.

[0035] The aforementioned stop unit includes a first vertical plate 24 fixedly connected to the bottom surface of the outer casing 3, and the top end of the first connecting rod 11 extends to the space between two adjacent first vertical plates 24. A connecting pipe 21 is provided between two adjacent first vertical plates 24. The connecting pipe 21 passes through the first connecting rod 11 and is fixedly connected to it. A through hole is provided on the first vertical plate 24 to cooperate with the connecting pipe 21, so that the connecting pipe 21 passes through the through hole and rotates with the first vertical plate 24.

[0036] An annular groove, coaxial with the through hole, is formed on the first vertical plate 24. Multiple locking teeth 25 arranged in a circular array are provided on the inner wall of the annular groove. A sliding rod 27 is slidably arranged inside the connecting tube 21. The sliding rod 27 is columnar and has a strip groove 28 on its outer side. A protrusion 30 is provided inside the strip groove 28. A locking strip 22 that cooperates with the locking teeth 25 is provided on the outer peripheral wall of the connecting tube 21. The locking strip 22 passes through the connecting tube 21 and extends into the strip groove 28. In actual use, when the locking strip 22 is squeezed by the protrusion 30 to protrude to the outside of the connecting tube 21 and engage with the locking teeth 25 in the annular groove, the first connecting rod 11 is stationary relative to the first vertical plate 24 and cannot rotate relative to it, which helps to maintain the stability of the outer shell 3 after adjustment.

[0037] To drive the slide bar 27 to slide within the connecting tube 21, a pull rope 16 is provided at one end of the slide bar 27. Specifically, one end of the pull rope 16 is fixedly connected to the end face of one end of the slide bar 27. Grooves are provided on both sides of the top of the outer casing 3, and a slider 15 is slidably connected inside the groove. Specifically, the cross-sectional shape of the slider 15 and the groove is T-shaped, which helps to prevent the slider 15 from detaching from the outer casing 3. The end of the pull rope 16 away from the slide bar 27 extends through the end face of the connecting tube 21 and into the outer casing 3, where it is fixedly connected to the slider 15. The pull rope 16 slides in cooperation with the outer casing 3 and the connecting tube 21. A sliding plate 5 for user operation is fixedly connected to the top surface of the slider 15. In actual use, a second spring 26 is also provided inside the connecting tube 21. The second spring 26 is located at the end of the slide bar 27 away from the pull rope 16 and is positioned between the slide bar 27 and the connecting tube 21.

[0038] In actual use, when the angle of the signature terminal needs to be adjusted, the user can slide the slide plate 5 downwards, causing the slide plate 5 to drive the slider 15 to slide away from the pull rope 16 within the slide groove. At this time, the pull rope 16 can drive the slide rod 27 to slide within the connecting tube 21, thereby causing the protrusion 30 on the slide rod 27 to move to one side and disengage from the locking strip 22. When the protrusion 30 disengages from the locking strip 22, the locking strip 22 slides downwards into the slide rod 27 and separates from the locking teeth 25 on the first vertical plate 24, thus causing the first vertical plate 24 to lose its limiting relationship with the connecting tube 21. The first connecting rod 11 can also rotate relative to the signature terminal. Thus, the angle of the outer shell 3 and the signature terminal can be adjusted from the top of the workbench 31. When the signature terminal is rotated to a suitable angle for reading and signing, the angle can be adjusted. When the angle is adjusted, the slide plate 5 is released. At this time, under the action of the second spring 26, the slide rod 27 can be driven to return to its original position. After the slide rod 27 returns to its original position, the protrusion 30 is placed at the bottom of the card strip 22 and squeezes the card strip 22 to the outside of the connecting tube 21 and engages with the card tooth 25 in the annular groove. When the card strip 22 engages with the card tooth 25, the connecting tube 21 cannot rotate relative to the first vertical plate 24, thereby preventing the first connecting rod 11 from rotating relative to the outer shell 3, so that the signing terminal after the angle is adjusted remains stable. In addition, in actual use, a magnetic strip 29 can be fixedly connected to the bottom of the strip groove 28, and the card strip 22 is made of metal iron. When the protrusion 30 and the card strip 22 are misaligned, the magnetic strip 29 attracts the card strip 22 to slide down quickly into the connecting tube 21 and separates it from the card tooth 25.

[0039] like Figure 3-6 As shown, the limiting unit includes a protrusion 20 slidably disposed on the second connecting shaft 14. Specifically, a blind hole is provided on the outer circumferential surface of the second connecting shaft 14, and the columnar protrusion 20 is slidably disposed inside the blind hole. In addition, a first spring 19 is provided at one end of the protrusion 20 inside the blind hole. The two ends of the first spring 19 are fixed to the blind hole and the opposite side of the protrusion 20, respectively. When the protrusion 20 slides to the outside of the blind hole due to its own weight, it is placed at the bottom end of the sleeve 13 to limit it, thereby preventing the first connecting shaft 12 from sliding relative to the second connecting shaft 14.

[0040] The drive assembly includes a limiting block 18 fixedly disposed on the inner wall of the sleeve 13. The top end of the second connecting shaft 14 extends into the sleeve 13 and slides therewith. A limiting groove 17 that cooperates with the limiting block 18 is provided on the outer circumferential surface of the second connecting shaft 14 above the protrusion 20. The limiting groove 17 is spiral in shape. When the top end of the second connecting shaft 14 is placed inside the sleeve 13, the limiting block 18 slides inside the limiting groove 17.

[0041] During the actual signing process, since the outer shell 3 and the signing terminal are in an inclined state, the protrusion 20 can overcome the tension of the first spring 19 under its own weight and slide outward to the bottom of the sleeve 13. This prevents the second connecting shaft 14 from sliding relative to the sleeve 13, which helps to keep the pin 8 parallel to the glass panel 1, allowing the outer shell 3 and the signing terminal to rotate relative to the glass panel 1. After the signing terminal is used, the sliding plate 5 can be slid down to release the locking relationship between the connecting tube 21 and the first vertical plate 24, allowing the outer shell 3 to rotate relative to the first connecting rod 11. At this time, the outer shell 3 can be rotated upward to... At the extreme position, the outer shell 3 is in contact with and parallel to the first connecting shaft 12 and the second connecting shaft 14. Then, the outer shell 3 rotates upwards around the pin 8 to a vertical position. During this process, the outer shell 3 simultaneously rotates the first connecting shaft 12 and the second connecting shaft 14 upwards to a vertical position. When the first connecting shaft 12 and the second connecting shaft 14 are in a vertical position, the protrusion 20 is also relatively vertical. Therefore, under the action of the first spring 19, the protrusion 20 can move into the blind hole. In actual use, multiple ball bearings can be rotatably installed on the outside of the protrusion 20 to reduce the friction between the protrusion 20 and the sleeve. The friction between the sleeves 13 and 13 allows the first spring 19 to more easily pull the protrusion 20 into the blind hole and separate it from the sleeve 13. At this time, under the gravity of the signing terminal and the outer shell 3, the sleeve 13 can slide downward relative to the first connecting shaft 12. Since the limiting block 18 is placed inside the limiting groove 17, when the first connecting shaft 12 drives the protrusion 20 to slide in the limiting groove 17, it can drive the second connecting shaft 14 to rotate, thereby driving the base 6 to rotate relative to the worktable 31. When the protrusion 20 slides down from the top of the limiting groove 17 to the bottom of the limiting groove 17, the second connecting shaft 14 drives the base 6 to rotate synchronously by 90°. This makes the pin 8 on the base 6 perpendicular to the glass panel 1, so that the second connecting shaft 14 can only rotate in a direction parallel to the glass panel 1. As a result, the outer shell 3 and the signing terminal cannot rotate relative to the glass panel 1, achieving a self-locking effect. At this time, there is a small gap between the signing terminal and the glass panel 1. In order to seal this gap, a sealing strip 4 is fixedly installed on the outer side of the top surface of the outer shell 3. When the outer shell 3 rotates to the vertical position, the sealing strip 4 contacts the glass panel 1 to seal the gap between the outer shell 3 and the glass panel 1, thereby preventing external dust from falling onto the screen of the signing terminal and helping to protect it.

[0042] In summary, this device, through the cooperation of the limiting unit and the driving unit, achieves a self-locking effect by utilizing the gravity of the signing terminal when the outer casing 3 rotates to the side of the glass panel 1 and is in a vertical state. This prevents the outer casing 3 and the signing terminal from rotating relative to the glass panel 1, thus storing the signing terminal and preventing dust from falling onto the screen of the signing terminal, providing good protection for it.

[0043] like Figure 1 As shown, a baffle 9 is fixedly connected to the top of the base 6 near the glass panel 1. When the limiting block 18 and the limiting groove 17 cooperate to drive the second connecting shafts 14 on both sides to rotate relative to each other, the baffles 9 on the two bases 6 will rotate to the outside, thereby preventing the outer shell 3 from swaying left and right when stored. In actual application, the limiting grooves 17 on the two second connecting shafts 14 are screwed in opposite directions, so that when the limiting block 18 and the limiting groove 17 cooperate, they can drive the two second connecting shafts 14 to rotate relative to each other.

[0044] To prevent the slide rod 27 from rotating relative to the connecting pipe 21, a guide groove 23 is provided on the inner wall of the connecting pipe 21, and a guide block that slides in cooperation with the guide groove 23 is fixedly connected to the outer circumferential surface of the slide rod 27, so that the slide rod 27 and the connecting pipe 21 can rotate synchronously.
