Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, and in particular to a portable electronic information device. Background Technology

[0002] With the rapid development of the logistics and warehousing industry, handheld electronic information collection terminals have been widely used in inventory and warehouse management. Staff need to hold these devices for long periods of time to scan and input barcodes on the shelves. In order to ensure battery life and grip stability, the existing handheld terminal devices are large in size and weight.

[0003] Existing handheld barcode scanners mainly adopt an integrated gun-shaped design, with the handle and scanning head connected at a fixed angle. This fixed structure results in a large overall space occupied by the device when not in use. When staff need to climb shelves or perform other handling operations, it is difficult to put the bulky barcode scanner into their pockets or bags for easy carrying.

[0004] This fixed and non-retractable structure limits the flexibility of handheld barcode scanners. When it is necessary to collect data on labels on goods at high or low locations, staff must bend over significantly or elevate their bodies to adjust the scanning angle, causing inconvenience. At the same time, the non-foldable structure makes the device take up a lot of space during relocation, which not only increases the carrying burden but also increases the risk of the handheld barcode scanner being bumped and damaged during transport.

[0005] Therefore, this utility model proposes a portable electronic information device to address the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems of existing handheld electronic barcode scanners, such as bulky overall structure leading to inconvenience in carrying and storage, difficulty in adjusting the scanning angle, and lack of effective protection for the scanning lens which easily accumulates dust and reduces the recognition rate, this utility model aims to provide a portable electronic information device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a portable electronic information device, including: a barcode scanning module, and a retractable folding mechanism installed at the bottom of the barcode scanning module.

[0008] The shrinking and folding mechanism has the structural features of being able to fold at multiple angles and adjust its length.

[0009] Furthermore, a fixing plate is fixedly connected to the rear side of the bottom wall of the scanning module, and a first gripping tube is provided between the fixing plates. The top end of the first gripping tube is rotatably connected to the fixing plate through a first damping shaft. A second gripping tube is slidably connected inside the first gripping tube. The second gripping tube can be housed inside the first gripping tube. The bottom end of the second gripping tube is rotatably connected to a battery box through a second damping shaft. The first damping shaft and the second damping shaft are used to provide rotational damping force to achieve angle positioning.

[0010] Preferably, the first grip tube and the second grip tube each have locking holes equidistantly spaced along their length on one sidewall. The retractable folding mechanism also includes a pin, which is inserted into the locking hole at the overlapping position of the first grip tube and the second grip tube to lock the relative positions of the first grip tube and the second grip tube by means of mechanical locking.

[0011] Preferably, the scanning module is provided with a module protection mechanism on its exterior. The module protection mechanism includes a first protective sleeve and a second protective sleeve. The first protective sleeve is engaged with the front end of the scanning module, and the second protective sleeve is engaged with the rear end of the scanning module. A connecting strap is fixedly connected between the adjacent sidewalls of the first protective sleeve and the second protective sleeve. The first protective sleeve and the second protective sleeve are connected to the scanning module through the connecting strap.

[0012] Preferably, the first protective sleeve has an annular groove on one end face near the scanning module, and the first protective sleeve is interference-fitted with the front edge of the scanning module through the annular groove.

[0013] Preferably, a dustproof sheet is fixedly connected to the inner ring of the first protective sleeve on the side near the scanning module, and the dustproof sheet covers the front of the scanning end of the scanning module.

[0014] Preferably, the first protective sleeve has straight grooves at both the upper and lower ends. The straight grooves are located on the same vertical axis and in front of the dustproof sheet. Sliding blocks are slidably connected inside the straight grooves, and the sliding blocks are respectively distributed on the left and right sides of the straight grooves.

[0015] Preferably, a sliding plate is fixedly connected to the side wall of the slider away from the center of the dustproof sheet, and a cleaning block is fixedly connected to the inner side of the sliding plate. The side surface of the cleaning block facing the dustproof sheet is in contact with the outer surface of the dustproof sheet, and is used to clean the dust on the surface of the dustproof sheet when the slider slides.

[0016] Preferably, the left and right outer walls of the first protective sleeve are provided with storage grooves, which are connected to the linear slide groove; the cleaning block has an open arc-shaped structure, and the storage groove is used to accommodate the slide plate and the cleaning block when cleaning is finished, so that the cleaning block avoids the scanning range of the barcode scanning module.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model solves the problems of existing handheld barcode scanners being bulky and inconvenient to carry, as well as the difficulty in adjusting the scanning angle when facing goods at high or low positions, by setting a retractable and folding mechanism containing a double-damped rotating shaft and a multi-section telescopic tube at the bottom of the barcode scanning module. It achieves the effect of freely adjusting the grip length and angle according to the operation requirements, and can be folded and stored to reduce the volume occupied when not in use, which significantly improves the portability and operational flexibility of electronic information equipment.

[0019] 2. This utility model solves the problems of weak protection capabilities of existing barcode scanning devices, which are easily damaged by drops, and the lack of convenient cleaning methods after dust accumulation on the lens dust cover, which affects the recognition accuracy, by setting front and rear protective sleeves connected by elastic bands on the outside of the barcode scanning module and integrating a sliding arc-shaped cleaning component at the front end. It achieves the effect of providing flexible buffer protection while being able to remove dust from the surface of the dust cover at any time through sliding operation, ensuring barcode scanning sensitivity and effectively extending the service life of electronic information equipment.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0030] Example:

[0031] Please refer to Figures 1 to 7 This utility model provides a portable electronic information device, which aims to solve the problems of existing handheld barcode scanners being bulky and inconvenient to store, difficult to adjust the scanning angle, and having lenses that lack effective protection and are prone to dust accumulation, leading to a decrease in recognition rate.

[0032] Please refer to Figure 1 , Figure 2 and Figure 3 The portable electronic information device includes a barcode scanning module 1, a retractable folding mechanism 2 installed at the bottom of the barcode scanning module 1, and a module protection mechanism 3 covering the outside of the barcode scanning module 1. The barcode scanning module 1 is mainly used to photoelectrically scan and collect information from the barcode on the surface of goods and store the information. The retractable folding mechanism 2 is mainly used to provide handheld support and to realize the storage and angle adjustment of the electronic information device through structural deformation. The module protection mechanism 3 is used to provide drop protection and dust removal function for the lens surface.

[0033] Please refer to Figure 2 , Figure 3 and Figure 4Two fixing plates 201 are fixedly connected to the rear side of the bottom wall of the barcode scanning module 1 by bolts. The two fixing plates 201 are symmetrically distributed and extend vertically downward. A first grip tube 202 is provided between the two fixing plates 201. The top end of the first grip tube 202 is rotatably connected to the two fixing plates 201 through a first damping shaft 203. The two ends of the first damping shaft 203 are respectively embedded in the inner sidewall of the two fixing plates 201. The first grip tube 202 can be rotated and adjusted in the front and back direction relative to the barcode scanning module 1 around the axis of the first damping shaft 203. The first grip tube 202 is a hollow tubular structure.

[0034] A second gripping tube 204 is slidably connected to the inner wall of the bottom end of the first gripping tube 202. The outer diameter of the second gripping tube 204 is adapted to the inner diameter of the first gripping tube 202. The second gripping tube 204 can reciprocate linearly up and down along the axial direction of the first gripping tube 202, thereby allowing the second gripping tube 204 to be stored inside the first gripping tube 202 or pulled out from the first gripping tube 202. The bottom end of the second gripping tube 204 is rotatably connected to a battery box 208 via a second damping pivot 207. The battery box 208 is used to hold the battery to power the barcode scanning module 1. At the same time, the battery box 208 serves as a base to increase the bottom counterweight when holding the device. The first damping shaft 203 and the second damping shaft 207 are both composed of a shaft core, a friction damping plate, an elastic clamping component, and an adjusting nut. The rotational damping torque is generated by the elastic component clamping the friction pair. The damping magnitude can be adjusted by turning the adjusting nut to change the clamping force, thereby enabling the first grip tube 202, the second grip tube 204, and the battery box 208 to be suspended and positioned at any angle.

[0035] The first grip tube 202 has multiple locking holes 205 equidistantly spaced along its length on one side wall, and the second grip tube 204 also has multiple locking holes 205 equidistantly spaced along its length on one side wall. When adjusted to a suitable length, the locking holes 205 on the first grip tube 202 and the locking holes 205 on the second grip tube 204 are located on the same horizontal axis. The retractable folding mechanism 2 is also equipped with a pin 206, which can be inserted from the outside and pass through the locking holes 205 on the first grip tube 202 and the second grip tube 204 in sequence. The pin 206 restricts the sliding of the second grip tube 204 relative to the first grip tube 202 by mechanical locking, thereby locking the total length of the retractable folding mechanism 2.

[0036] Please refer to Figure 5 and Figure 6The module protection mechanism 3 includes a first protective sleeve 301 located at the front end and a second protective sleeve 304 located at the rear end. The first protective sleeve 301 has an annular groove 302 along its edge on the side face near the barcode scanning module 1. The cross-sectional shape and size of the annular groove 302 are adapted to the shape and size of the edge of the front shell of the barcode scanning module 1. The first protective sleeve 301 is tightly fitted to the front end of the barcode scanning module 1 through the annular groove 302 in an interference fit. The annular groove 302 is used to limit the displacement of the first protective sleeve 301 relative to the barcode scanning module 1 in the up, down, left, and right directions. The second protective sleeve 304 is connected to the rear edge of the barcode scanning module 1 in the same snap-fit ​​manner.

[0037] Connecting straps 303 are fixedly connected between the adjacent sidewalls on the left and right sides of the first protective sleeve 301 and the second protective sleeve 304. The connecting straps 303 are made of rubber with high resilience. The two connecting straps 303 pull the first protective sleeve 301 and the second protective sleeve 304 towards the middle through their own elastic tension, so that the first protective sleeve 301 and the second protective sleeve 304 firmly hold the barcode scanning module 1. The connecting straps 303 are used to prevent the first protective sleeve 301 and the second protective sleeve 304 from separating when the electronic information equipment is dropped, thereby ensuring that the first protective sleeve 301 and the second protective sleeve 304 can continuously provide cushioning protection for the outer shell and internal components of the barcode scanning module 1.

[0038] Please refer to Figure 6 The inner ring of the first protective sleeve 301 is fixedly connected to the side of the barcode scanning module 1 by adhesive with a dustproof sheet 305. The dustproof sheet 305 is located in front of the scanning end of the barcode scanning module 1 and completely covers the scanning window. The dustproof sheet 305 is made of tempered glass with high light transmittance. The dustproof sheet 305 is used to isolate the external environment from the precision optical lens of the barcode scanning module 1, preventing dust and moisture in the air from directly contacting the lens surface of the barcode scanning module 1. At the same time, the dustproof sheet 305 can also prevent sharp objects from scratching the lens of the barcode scanning module 1.

[0039] In a preferred embodiment, the upper and lower end faces of the first protective sleeve 301 are provided with linear grooves 306. The two linear grooves 306 are located on the axis of the same vertical plane and are located in front of the dustproof sheet 305. The cross-section of the linear groove 306 is dovetail-shaped to prevent internal parts from falling off. Each linear groove 306 has two sliders 308 slidably connected inside. The two sliders 308 are respectively distributed on the left and right sides of the linear groove 306 and can reciprocate linearly along the length of the linear groove 306.

[0040] In a preferred embodiment, a sliding plate 309 is fixedly connected to the side wall of the slider 308 away from the center of the dustproof sheet 305 by adhesive or snap-fit. The sliding plate 309 has an arc-shaped plate structure. A cleaning block 310 is fixedly connected to the inner ring side wall of the sliding plate 309. The cleaning block 310 is made of soft rubber material. The side surface of the cleaning block 310 facing the dustproof sheet 305 is in close contact with the outer surface of the dustproof sheet 305. The vertical length of the cleaning block 310 covers the vertical height of the dustproof sheet 305.

[0041] In a preferred embodiment, the left and right outer walls of the first protective sleeve 301 are provided with a storage groove 307, which is connected to the interior of the straight slide groove 306. The cleaning block 310 has an open arc-shaped structure, and the curvature of the cleaning block 310 matches the curvature of the edge of the dustproof sheet 305. When the sliding plate 309 slides to the extreme position on both sides, the sliding plate 309 together with the cleaning block 310 can be completely stored in the interior of the storage groove 307. At this time, the cleaning block 310 is located in the edge area of ​​the first protective sleeve 301.

[0042] Working principle: When staff use electronic information equipment for barcode scanning, the scanning module 1 scans the barcode on the surface of the goods and stores the data. When the grip length needs to be adjusted to adapt to different working environments, the staff manually pulls the second grip tube 204, causing it to slide downwards inside the first grip tube 202 until the locking hole 205 at the bottom of the first grip tube 202 and the locking hole 205 at the top of the second grip tube 204 are at the same horizontal level. At this point, the pin 206 is inserted into the aligned locking hole 205. The pin 206 uses its rigid structure to restrict the retraction or disengagement of the second grip tube 204, thereby fixing the grip length. The staff then grips the second grip tube. Operation can be performed using either the first grip tube 202 or the second grip tube 204. If encountering corners or goods at different heights, the operator can adjust the angle of the first grip tube 202 relative to the barcode scanning module 1 by rotating the first damping shaft 203, or adjust the angle of the battery box 208 relative to the second grip tube 204 by rotating the second damping shaft 207. When the first damping shaft 203 and the second damping shaft 207 become loose and cannot be detected, the damping can be adjusted by turning the adjusting nut to change the clamping force, so that the electronic information equipment can be kept at any angle after adjustment. The battery box 208 acts as a counterweight to prevent the electronic information equipment from being top-heavy and also provides a storage place for the batteries that supply power.

[0043] When the electronic information equipment is accidentally collided or dropped during use, the first protective sleeve 301 at the front end and the second protective sleeve 304 at the rear end first contact the external object to absorb the impact. The first protective sleeve 301 uses the annular groove 302 to tightly hold the edge of the barcode scanning module 1 to prevent it from falling off. At the same time, the connecting strap 303 uses the elastic contraction force to always pull the first protective sleeve 301 and the second protective sleeve 304 towards the center. The connecting strap 303 prevents the two protective sleeves from separating at the moment of force, thereby ensuring that the protective sleeves can continuously provide buffer protection for the outer shell and internal components of the barcode scanning module 1.

[0044] When dust adheres to the surface of the dustproof sheet 305 and affects the recognition sensitivity of the barcode scanning module 1, the operator pushes the slider 308 located in the linear slide 306 with their finger. The slider 308 drives the slide plate 309 and the inner cleaning block 310 to move laterally along the surface of the dustproof sheet 305. Since the cleaning block 310 is in close contact with the surface of the dustproof sheet 305, the friction during the movement wipes away the dust on the surface of the dustproof sheet 305. After cleaning, the operator pushes the slider 308 to the leftmost or rightmost end of the linear slide 306. At this time, the slide plate 309 drives the cleaning block 310 to completely enter the storage slot 307. Since the cleaning block 310 has an open arc structure, the cleaning block 310 can fit the edge of the first protective cover 301 and hide, thereby preventing the cleaning block 310 from blocking the scanning light path of the barcode scanning module 1.
