[0042] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0044] like Figures 1-10As shown, the embodiment of the present application proposes a multifunctional all-in-one pen, comprising a pen body 1, which has a top end 11 and a bottom end 12 arranged opposite to each other along the axial direction of the pen body 1, and a writing portion 13 is provided at the bottom end 12 of the pen body 1; a lighting component 2 is provided on the outer wall of the pen body 1 near the top end 11; a camera component 3 is provided on the outer wall of the pen body 1 near the top end 11 and is staggered with the lighting component 2; Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the tape measure assembly includes a tape measure 43, a limiting assembly 5 and a winding drum 4. The winding drum 4 is coaxially sleeved on the outer peripheral wall of the pen body 1 near the top end 11. The winding drum 4 has two constraint plates 41 axially spaced along the pen body 1. The constraint plates 41 are circular plates. The two constraint plates 41 are coaxially arranged with the pen body 1. The arrangement of the two constraint plates 41 enables, when the pen body 1 is not in use and placed on the desktop, the pen body 1 is supported by the two constraint plates 41, so that one end of the pen body 1 equipped with the lighting assembly 2 and the camera assembly 3 is in a suspended state, thereby preventing the lighting assembly 2 and the camera assembly 3 from contacting the desktop, so as to protect the lighting assembly 2 and the camera assembly 3 and avoid wear and tear; the area between the two constraint plates 41 constitutes a winding chamber 42 for accommodating the tape measure 43; the limiting assembly 5 is used to limit the free end of the tape measure 43. When the measuring tape 43 is not in use, it is stored within the winding chamber 42. The free end of the measuring tape 43 is positioned on the winding drum 4 by the stopper assembly 5 to prevent it from detaching from the winding drum 4. When the measuring tape 43 is needed, the stopper assembly 5 is controlled to release the positioning of the free end of the measuring tape 43. The free end of the measuring tape 43 is then manually pulled and released from the winding drum 4 for measurement. A battery assembly, located within the pen body 1, is used to power the lighting assembly 2 and the camera assembly 3.

[0045] During specific use, the user can control the lighting component 2 or the camera component 3 to turn on according to the usage scenario to meet the needs of multi-scene use; the lighting component 2 helps the user to complete the corresponding drawing design work in a low-light environment, and the camera component 3 can be used to record a certain range of scenes, and to store on-site images so that the cartographer can review the real scene, thereby improving the cartographer's work efficiency; the tape measure 43 can be released through the tape measure component to facilitate the cartographer to measure the size of the object, and the tape measure 43 can be stored on the tape measure component when not in use; this solution integrates the lighting component 2, the camera component 3, and the tape measure 43 for measuring size into the pen body 1, which can realize multiple functions such as writing, measuring, video recording, and lighting in one. At the same time, the above-mentioned components are integrated into the pen body 1, which is also convenient to carry when working outdoors, avoiding the inconvenience of carrying and easy loss due to separate storage; Figure 2As shown, when the pen body 1 is not in use and placed on a table, the winding tube 4 protrudes from the pen body 1, effectively preventing contact between the lighting assembly 2 and the camera assembly 3 and the table surface. This reduces the likelihood of wear and tear on the lighting assembly 2 and the camera assembly 3 caused by frequent contact with the table surface, helping to protect the lighting assembly 2 and the camera assembly 3 and extend their service life. The measuring tape 43 in this embodiment is made of lightweight fabric, which helps reduce the weight of the pen body 1.

[0046] In some embodiments of the present application, Figure 6 As shown, a clamping post 431 is provided at the free end of the tape measure 43 along the width direction of the tape measure 43; the limiting assembly 5 includes a constraint hole 51 that is set along the thickness direction of the constraint plate 41 and matches the clamping post 431. The constraint holes 51 on the two constraint plates 41 are arranged coaxially, and an embedded channel 52 is provided along the radial direction of the constraint plate 41 to connect the constraint hole 51 with the outside world. The embedded channel 52 is set along the thickness direction of the constraint plate 41; the two ends of the clamping post 431 respectively enter and clamp into the constraint hole 51 through the corresponding embedded channel 52. Figure 5 As shown, the clamping column 431 is clamped in the constraint hole 51 and limits the free end of the tape measure 43. A rubber layer can be covered on the inner wall of the constraint hole 51, so that when the clamping column 431 is clamped in the constraint hole 51, the friction resistance between the clamping column 431 and the constraint hole 51 is increased to prevent the clamping column 431 from withdrawing from the constraint hole 51, thereby ensuring reliable positioning of the free end of the tape measure 43.

[0047] In some embodiments of the present application, in order to further improve the positioning effect of the free end of the tape measure 43, the present embodiment makes the following improvements: the two ends of the clamping column 431 are respectively extended out of the constraint plate 41 along the axial direction of the pen body 1, and a limiting plate 432 is coaxially provided at one end of the clamping column 431 extending out of the constraint plate 41 and fits with the outer wall of the constraint plate 41; magnetic sheets are provided at the fitting part between the outer wall of the constraint plate 41 and the corresponding limiting plate 432, and at the side of the limiting plate 432 facing the constraint plate 41. When the clamping column 431 is clamped in the constraint hole 51, with the cooperation of the two limiting plates 432, the clamping column 431 is positioned along the axial direction of the pen body 1. At the same time, through the setting of the magnetic sheet, the clamping column 431 can be more firmly clamped in the constraint hole 51, further improving the positioning effect of the free end of the tape measure 43.

[0048] In some embodiments of the present application, Figure 5As shown, the outer circumferential walls of the two restraining plates 41 are correspondingly provided with straight portions 411. There are one or more straight portions 411, and the plurality of straight portions 411 are spaced apart along the circumference of the restraining plates 41. The arrangement of the straight portions 411 ensures that when the pen body 1 is not in use and placed on a table, the straight portions 411 on the restraining plates 41 contact the table surface, effectively preventing the pen body 1 from rotating freely while placed on the table surface, thereby achieving a certain degree of positional restraint for the pen body 1.

[0049] In some embodiments of the present application, Figure 1 As shown, the pen body 1 further includes a measuring ruler 14 provided on the outer peripheral wall near the bottom end 12. The measuring ruler 14 extends along the axial direction of the pen body 1, and the pen body 1 can be transformed into a measuring ruler at any time. The measuring ruler 14 on the pen body 1 can be used to conveniently measure objects of smaller sizes and can be used at any time as needed.

[0050] In some embodiments of the present application, Figure 1 、 Figure 2 As shown, it also includes a blade 6 arranged at the top 11 and retractable along the axial direction of the pen body 1. When it is needed, it is extended from the pen body 1, and when it is not needed, it is retracted into the pen body 1, which is convenient for the designer to use.

[0051] In some embodiments of the present application, Figure 7 As shown, the blade 6 is placed in the pen body 1 and is connected to an operating rod 61 extending outward from the pen body 1 at one end along the radial direction of the pen body 1. A first through-hole 17 is provided on the pen body 1 for allowing the operating rod 61 to extend outward. The first through-hole 17 extends along the axial direction of the pen body 1. A sliding key 62 is connected to the end of the operating rod 61 extending out of the pen body 1. A first sliding groove 15 is provided on the outer wall of the pen body 1 for sliding assembly with the sliding key 62. The first sliding groove 15 is connected to the first through-hole 17. When the blade 6 needs to be used, the user pushes the sliding key 62 with a finger and slides it along the first sliding groove 15, so that the blade 6 is extended from the pen body 1. When not in use, the user moves the sliding key 62 in the opposite direction with a finger, so that the blade 6 is retracted into the pen body 1. When the blade 6 is not in use, in order to improve the positioning effect of the blade 6, a rubber layer can be covered on the inner wall of the first sliding groove 15 to increase the friction resistance between the sliding key 62 and the first sliding groove 15, thereby achieving a certain degree of positioning effect on the blade 6.

[0052] In some embodiments of the present application, Figure 1 、 Figure 9 As shown, the lighting assembly 2 includes a lighting circuit 22 and an LED lamp 21. The LED lamp 21 is arranged on the outer wall of the pen body 1 and is connected to the lighting circuit 22. Figure 1 、 Figure 10As shown, the camera assembly 3 includes a camera 31, a processor module 32, and a camera circuit 33. The camera 31 is arranged on the outer wall of the pen body 1 and is connected to the processor module 32. The camera 31 and the processor module 32 are both connected to the camera circuit 33. The battery assembly is connected to a control switch 7, which is used to control the lighting circuit 22 or the camera circuit 33 to be connected to the battery assembly. This embodiment provides a specific implementation method of controlling the lighting circuit 22, the camera circuit 33 and the battery assembly with the control switch 7: Figure 7 As shown, a second slide groove 19 is provided on the outer wall of the pen body 1, and the control switch 7 is slidably assembled in the second slide groove 19. A rubber layer can be provided in the second slide groove 19 to increase the friction resistance between the control switch 7 and the second slide groove 19 to prevent the control switch 7 from accidentally moving in the second slide groove 19; Figure 8 As shown, a connecting rod 72 extending into the pen body 1 is connected below the control switch 7. A second through-hole 18 is provided on the pen body 1 for the connecting rod 72 to pass through, and the second through-hole 18 extends along the length direction of the second slide 19. Two first contacts 221 are provided at intervals at the bottom of the connecting rod 72 (the contact portions between the first contacts 221 and the connecting rod 72 are insulated). The two first contacts 221 are connected to the positive and negative electrodes of the battery assembly via wires. Figure 9 、 Figure 10 As shown, the lighting circuit 22 is provided with two second contacts 331 at intervals (the two second contacts 331 are fixedly installed at appropriate positions in the pen body 1 and are insulated from the pen body 1), and the lighting circuit 22 is disconnected at the two second contacts 331. The camera circuit 33 is provided with two third contacts 71 at intervals (the two third contacts 71 are fixedly installed at appropriate positions in the pen body 1 and are insulated from the pen body 1), and the camera circuit 33 is disconnected at the two third contacts 71. When the control switch 7 is in the middle position of the second slide slot 19, the first contact 221 is in contact with the second contact 331 and the third contact 71. 71 are not in contact, the camera circuit 33 and the lighting circuit 22 are both in the disconnected state, the control switch 7 is moved and moved along the second slide 19 toward the top 11 to the set position, so that the two first contacts 221 are in contact with the two third contacts 71 respectively, then the camera circuit 33 is connected to the battery assembly, and the camera function is enabled; the control switch 7 is moved and moved along the second slide 19 toward the bottom 12 to the set position, so that the two first contacts 221 are in contact with the two second contacts 331 respectively, then the lighting circuit 22 is connected to the battery assembly, and the lighting function is enabled. The processor module 32 in this solution includes a photoelectric conversion device, a video processing circuit, and a recording and storage module. The camera 31 selects a certain range of scenes through the lens, converts it into an electrical signal through the photoelectric conversion device, sends it to the video processing circuit for correction and processing, and stores it in the recording and storage module to realize image storage; such as Figure 4As shown, a USB interface 16 connected to the recording storage module is provided on the outer wall of the pen body 1. The video can be viewed on the monitor by connecting the computer through the USB interface 16, so as to review the scene in a convenient and effective manner.

[0053] In some embodiments of the present application, the battery assembly in this solution can be a dry cell battery or a storage battery, and can be configured accordingly according to actual needs.

[0054] The working process of the present invention is as follows: the user controls the lighting assembly 2 or the camera assembly 3 via the control switch 7 according to the needs of the usage scenario, thereby meeting the needs of multiple usage scenarios; the user selects the measuring ruler 14 or the measuring tape 43 according to the size of the object to be measured; when using the measuring tape 43 for measurement, the user first releases the limit of the free end of the measuring tape 43 by the limit assembly 5, then manually pulls the free end of the measuring tape 43 and releases it from the winding drum 4; when use is completed, the measuring tape 43 is rewound on the winding drum 4 and the clamping post 431 provided at the free end of the measuring tape 43 is re-engaged in the corresponding restraining hole 51; the blade 6 is controlled to extend or retract from the pen body 1 by moving the sliding key 62 to meet the user's various usage needs; when the pen body 1 is not in use, it is placed on a desktop, and the winding drum 4 acts to keep the end of the pen body 1 equipped with the lighting assembly 2 and the camera assembly 3 suspended in the air, thereby reducing the probability of contact between the lighting assembly 2 and the camera assembly 3 and the desktop, thereby avoiding wear.

[0055] In summary, the embodiment of the present invention provides a multifunctional all-in-one pen. This solution provides a winding tube 4 coaxially on the pen body 1 and a tape measure is wound on the winding tube 4 to facilitate the user to use for measurement; and the lighting component 2 and the camera component 3 provided on the pen body 1 are located on the inner side of the axial projection of the winding tube 4 along the axial direction of the pen body 1. When the pen body 1 is not in use and placed on a desktop, the part of the pen body 1 where the LED lamp 21 and the camera 31 are located can be suspended with the help of the winding tube 4 protruding from the pen body 1, so that they do not contact the desktop, effectively avoiding the contact between the camera 31, the LED lamp 21 and the desktop, and reducing the probability of wear and tear caused by the camera 31 and the LED lamp 21 moving back and forth relative to the desktop, thereby better protecting the camera 31 and the LED lamp 21 and increasing their service life.
