Description

Technical Field

[0001] The invention relates to the technical field of blackboard writing pens, in particular to a multifunctional electronic blackboard writing pen. Background Art

[0002] A blackboard pen is a tool used for writing on a blackboard or whiteboard, mainly used for teaching, meetings and presentations. It includes different types of pens, which vary depending on the surface used and the writing needs. Whiteboard pens use dry-erase ink, which can write smoothly on whiteboards and is easy to wipe off. Blackboard chalk is a traditional writing tool used for writing on blackboards. It is usually presented in powder form and can be easily erased with an eraser. Liquid chalk pens combine the characteristics of whiteboard pens and traditional chalks. They use liquid ink and can be written and wiped on blackboards or other specific surfaces. The choice of these pens depends on the writing surface and specific usage needs.

[0003] During teaching, meetings or demonstrations, there are situations where a laser pen is used to indicate content, a capacitive pen is used to perform touch operations on a smart display screen, or a translation pen is used to scan and translate text content. This requires the use of additional laser pens, capacitive touch pens and translation pens. However, the writing pens, laser pens, capacitive touch pens and translation pens in traditional technologies are not independent individuals, which results in operators needing to carry and manage multiple pens with different functions, increasing the burden of carrying and the complexity of management. In addition, switching between different pen bodies requires frequent picking up and placing on the table, which is time-consuming and laborious. Summary of the invention

[0004] The purpose of the present invention is to provide a multifunctional electronic blackboard pen to solve the technical problems raised in the above background technology.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 10The present invention provides a multifunctional electronic blackboard writing pen, including a blackboard writing pen head 01, a capacitive touch pen head 02, a laser pen head 03, a pen holder 1, an end cap 2 and a translation module 3. The pen holder 1 has a first cavity 101 on one side and a second cavity 102 on the other side. The end cap 2 is screwed on an end of the pen holder 1 close to the second cavity 102 by a thread, and the end cap 2 can be moved along the length direction of the pen holder 1 by tightening or loosening the end cap 2. The translation module 3 is arranged at an end of the pen holder 1 close to the first cavity 101. The translation module 3 can scan, identify and translate texts to realize the translation function, which is convenient for teaching and office work.

[0032] On the inner end wall of the first cavity 101, three guide grooves 11 are equidistantly arranged around the axis of the pen barrel 1, and the three guide grooves 11 intersect to form a cavity 111. The end of the end cap 2 has a telescopic hole 21, and the telescopic hole 21 is aligned with the cavity 111. A slide bar 12 extending along the length direction of the pen barrel 1 is installed in each guide groove 11 for limited sliding. The blackboard writing pen head 01, the blackboard writing pen head 01 and the laser pen head 03 are respectively installed on the ends of the three slide bars 12. The pen barrel 1 is also provided with a pushing mechanism 5, which is used to push one of the slide bars 12 to slide to the center of the cavity 111 when the end cap 2 is tightened. Among them, the blackboard writing pen head 01, the capacitive touch pen head 02 and the laser pen head 03 all adopt the existing technology, and the specific shape structure and working principle are not described in detail in the present invention.

[0033] Specifically, when the blackboard writing pen tip 01 needs to be used, the end cap 2 is tightened, and the end cap 2 slides along the outer wall of the pen holder 1 toward the side of the translation module 3, and at the same time cooperates with the pushing mechanism 5 to drive the sliding rod 12 connected to the blackboard writing pen tip 01 to slide to the center of the cavity 111. Then, while the sliding rod 12 connected to the blackboard writing pen tip 01 moves toward the center of the cavity 111, the blackboard writing pen tip 01 and the end cap 2 move relative to each other, and finally the blackboard writing pen tip 01 extends to the outside through the telescopic hole 21, and normal writing can be performed. The method of using the capacitive touch pen tip 02 and the laser pen tip 03 is the same as the method of using the above-mentioned blackboard writing pen tip 01, and the specific details are not repeated here. The capacitive touch pen tip 02 is used to realize the touch operation of the smart screen, and the laser pen tip 03 can be used to perform laser indication of the required content, so that the multifunctional electronic blackboard book has four functions of writing, touching, laser indication and text translation. Compared with the traditional pen body with single function, it does not need to be frequently taken out and replaced during use, which is easy to use and meets a variety of usage scenarios.

[0034] In addition, the components with translation functions are integrated on one side of the pen holder 1, and the blackboard writing pen head 01, capacitive touch pen head 02 and laser pen head 03 are integrated on the other side of the pen holder 1. The partitioned design helps to optimize the internal space layout of the pen holder 1, avoiding complex circuits and structures inside the device, thereby improving the overall design and ease of use of the pen.

[0035] In addition, the translation module 3 is partitioned with the blackboard pen head 01, the capacitive touch pen head 02 and the laser pen head 03. The translation module 3 is located alone at one end of the pen holder 1. When the user is writing, drawing, laser pointing and touch operation, the translation function can be used simultaneously without adjustment, which is more convenient to use. In addition, when the user is using the translation function, there is no need to worry about interference from the capacitive touch pen head 02 or the laser pen head 03. The overall structural layout is reasonable.

[0036] In addition, the multifunctional electronic blackboard pen also includes a protective cover 4, which is provided with a bayonet 41. A buckle 42 matching the bayonet 41 is received on the outer wall of the pen barrel 1 and on one side away from the end cap 2. The protective cover 4 is detachably fastened to the end of the pen barrel 1 through the cooperation of the bayonet 41 and the buckle 42, and covers the translation module 3 as a whole. When the translation module 3 is not in use, the protective cover 4 is fastened to the end of the pen barrel 1, which can provide a protective effect for the translation module 3 and prevent the translation module 3 from touching the ground and breaking.

[0037] Among them, a counterweight base 401 is fixed on the end of the protective cover 4, and the diameter of the counterweight base 401 is larger than the outer diameter of the protective cover 4. When the whole is idle, the counterweight base 401 is placed on the desktop or table top. Combined with the counterweight effect of the counterweight base 401 and its large contact support area with the desktop or table top, the whole can be placed vertically to avoid rolling and shifting when the whole is placed horizontally on the desktop or table top, thereby ensuring the stability of the whole when idle.

[0038] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 8 The pushing mechanism 5 includes three wedge-shaped sliders 51, three clamping heads 52, three push rods 53, a ring member 54 and a push arm 55. Three slide grooves 501 that are equidistantly connected to the second cavity 102 are arranged on the outer wall of the pen barrel 1 around the axis of the pen barrel 1. The slide grooves 501 extend along the length direction of the pen barrel 1 and correspond to the positions of the guide grooves 11 one by one. The wedge-shaped slider 51 is correspondingly limited and slidably installed in the slide groove 501. The clamping head 52 is fixed on the outer surface of the wedge-shaped slider 51. The push rod 53 is correspondingly fixed on the side of the slide rod 12 and abuts against the inclined surface of the wedge-shaped slider 51. The ring member 54 is rotatably installed on the end surface of the end cap 2. The push arm 55 is fixed on the end of the ring member 54 and extends along the length direction of the pen barrel 1. A clamping groove 551 for the push rod 53 to match and snap into is provided on the end of the push arm 55 away from the ring member 54.

[0039] When the blackboard writing pen tip 01 is needed, first rotate the adjusting ring 54 to align the slot 551 with the clamping head 52 corresponding to the position of the blackboard writing pen tip 01, then tighten the end cap 2 to the side of the translation module 3, and the end cap 2 drives the push arm 55 to move closer to the side of the clamping head 52 until the clamping head 52 matches and is clamped into the slot 551. As the end cap 2 continues to be pushed forward, the push arm 55 pushes the clamping head 52 and drives the wedge-shaped slider 51 to slide. Under the extrusion and cooperation between the inclined surface of the wedge slider 51 and the end of the push rod 53, the slide bar 12 corresponding to the position of the blackboard writing pen tip 01 can be pushed to slide toward the cavity 111, thereby realizing the centering of the blackboard writing pen tip 01. Finally, the blackboard writing pen tip 01 is extended from the telescopic hole 21, which is convenient for writing. The adjustment method of the capacitive touch pen tip 02 and the laser pen tip 03 is the same, and the specific details will not be repeated, so that the switching of the blackboard writing pen tip 01, the capacitive touch pen tip 02 and the laser pen tip 03 is convenient enough.

[0040] In addition, each guide groove 11 is provided with a first spring 121 extending radially along the pen holder 1, one end of the first spring 121 is fixed to the outer wall of the slide bar 12, and the other end is fixed to the inner end wall of the guide groove 11 away from the cavity 111. A second spring 122 is fixed on the outer wall of each slide bar 12 near its top end, and the extension direction of each second spring 122 is consistent with the first spring 121, and the other end of each second spring 122 is fixed to the inner wall of the first spring 121 accordingly. In the process of pushing the slide bar 12 to slide to the center of the cavity 111 under the extrusion action of the end of the wedge-shaped slider 51 and the push rod 53, the first spring 121 and the second spring 122 are stretched and stored. When the end cap 2 is loosened, the elastic reset effect of the first spring 121 and the second spring 122 can be used to drive the slide bar 12 to slide and reset to the guide groove 11, thereby realizing automatic reset of the slide bar 12, avoiding occupying the position of the cavity 111 and affecting the entry of other slide bars 12, making function switching and adjustment more convenient.

[0041] See also Figure 2 , Figure 3 and Figure 4The translation module 3 includes a translation head 31, a text recognition camera 32, a lamp bead array group 33, a pair of sliding contact feet 34 and a pair of micro-touch switches 35. The translation head 31 is arranged at one end of the pen holder 1 away from the end cap 2. The text recognition camera 32 is embedded on the inclined surface of the translation head 31. The lamp bead array group 33 is arranged in a ring array around the text recognition camera 32. Two sliding contact feet 34 are fixed on the end surface of the translation head 31. Two micro-touch switches 35 are correspondingly arranged at the ends of the sliding contact feet 34. When the translation function is used, the sliding contact feet 34 are supported on the paper and slide. By slightly pressing the pen holder 1, when the micro-touch switch 35 detects that the pressure reaches a preset range, the text recognition camera 32 and the lamp bead array group 33 are controlled to work. The text recognition camera 32 can shoot, scan and recognize the text for translation. The lamp bead array group 33 can play a role of fill light for the text recognition camera 32 to prevent insufficient shooting light from affecting text recognition.

[0042] See also Figure 1 , Figure 5 and Fig.10 A microprocessor 72, a memory 73, a controller 74 and a wireless transmission module 75 are installed on the inner wall of the first cavity 101. The text recognition camera 32, the memory 73 and the wireless transmission module 75 are electrically connected to the microprocessor 72 respectively, and the microprocessor 72 and the memory 73 are electrically connected. The capacitive touch pen head 02, the laser pen head 03, the text recognition camera 32, the lamp bead array group 33 and the micro-touch switch 35 are electrically connected to the controller 74 respectively. After the text recognition camera 32 shoots, the data is transmitted to the microprocessor 72, and the microprocessor 72 processes the data and compares it with the data stored in the memory 73, and finally translates the text into the required content. On the one hand, the microprocessor 72 can directly transmit the translation result to the display screen 7 for display, and on the other hand, the translation result can be wirelessly transmitted to the display screen 7 for playback through the wireless transmission module 75.

[0043] In addition, when the micro-touch switch 35 detects a certain pressing force, it sends a signal to the controller 74, and the controller 74 controls the text recognition camera 32 and the lamp array group 33 to work, thereby avoiding accidental touches.

[0044] Furthermore, a display screen 7 and a control button group 71 are provided on the outer wall of the pen barrel 1. The display screen 7 is electrically connected to the microprocessor 72, and the control button group 71 is electrically connected to the controller 74. By pressing the corresponding button on the control button group 71, the capacitive touch pen head 02 or the laser pen head 03 can be controlled to work, which is convenient for regulation.

[0045] See also Figure 5 and Fig.10A driving motor 301 is fixed on the inner end wall of the second cavity 102, and a shaft 302 extending along the length direction of the pen holder 1 is fixed on the output shaft of the driving motor 301, and a mounting seat 303 is fixed on the end of the shaft 302. The translation head 31 is mounted on the end surface of the mounting seat 303. The driving motor 301 is electrically connected to the controller 74. By pressing the corresponding button on the control button group 71, a signal is sent to the controller 74, and the controller 74 controls the driving motor 301 to work. The output shaft of the driving motor 301 drives the shaft 302 and the mounting seat 303 to rotate, and then drives the translation module 3 to rotate as a whole. The scanning direction of the translation module 3 as a whole can be adjusted so that the operator can use his dominant hand to perform scanning translation in two directions respectively, so that it is suitable for text translation with different sequential directions, and has high practicality.
