Description

Technical Field

[0001] This utility model relates to the technical field of handheld barcode scanning devices, and more particularly to a dual-screen handheld barcode scanning device. Background Technology

[0002] With the rapid development of industries such as mobile payment, retail inventory management, and logistics warehousing, handheld barcode scanners have become indispensable data collection tools. Currently, handheld barcode scanners on the market typically adopt a single display screen design. This screen primarily serves the operator, displaying data information, scanning results, and other information.

[0003] However, this single-screen design has significant limitations in practical applications, especially in scenarios requiring information interaction with customers. For example, when an operator needs to show a customer scan result (such as product price, payment amount, ticket information) or other prompts, the operator must turn the device screen towards the customer or hand the entire device to the customer for viewing. This not only reduces work efficiency but is also inconvenient to use, thus limiting its application in broader business environments that place greater emphasis on interactive experiences. Utility Model Content

[0004] The purpose of this application is to provide a dual-screen handheld barcode scanning device that combines the powerful functions of dual-screen devices, the portability of the foldable form, and the ease of operation of the self-supporting structure, effectively overcoming the shortcomings of existing technologies such as poor scene adaptability and inconvenient interaction.

[0005] The technical solution provided in this application is as follows:

[0006] A dual-screen handheld barcode scanner includes:

[0007] The host computer has a main screen on its front.

[0008] A secondary unit, wherein a secondary screen is provided on the front of the secondary unit;

[0009] A rotating mechanism is provided, through which the top of the auxiliary unit is rotatably connected to the top of the main unit, enabling the dual-screen handheld barcode scanner to have a folded state and an unfolded state.

[0010] In the folded state, the auxiliary unit is stacked on the back of the main unit;

[0011] In the unfolded state, the secondary unit and the main unit form an angle, and the bottom of the secondary unit and the main unit together constitute a support structure, enabling the dual-screen handheld barcode scanner to stand upright on a plane, with the main screen facing away from the secondary unit and the secondary screen facing away from the main unit.

[0012] In some implementations, in the folded state, the secondary screen is either away from the main unit or close to the main unit.

[0013] In some embodiments, a connecting portion protrudes from the top of the back of the host computer;

[0014] The auxiliary unit has a mounting groove at the top of its rear side. The connecting part is housed in the mounting groove and is rotatably connected to the auxiliary unit through the rotating mechanism.

[0015] In some embodiments, the top surface of the connector is flush with the top surface of the host and forms a mounting plane;

[0016] It also includes a sweeping dock, which is set on the mounting plane.

[0017] In some embodiments, a limiting part is provided in the mounting groove, which cooperates with the connecting part to limit the relative rotation angle between the auxiliary machine and the main machine.

[0018] In some embodiments, the rotating mechanism is a damping shaft, and the auxiliary machine is rotatably connected to the main machine through the damping shaft, so that the auxiliary machine can be fixed at any angle.

[0019] In some embodiments, the damping shaft includes a bushing and a shaft, one end of the bushing is fixedly connected to the auxiliary machine, and the other end of the bushing is provided with a mounting hole;

[0020] One end of the rotating shaft is fixedly connected to the main unit, and the other end of the rotating shaft is inserted into the mounting hole and is interference-fitted with the mounting hole. The damping rotating shaft achieves damped rotation through the friction between the rotating shaft and the bushing.

[0021] In some embodiments, a camera is also included, with the camera located on the front of both the main unit and the front of the secondary unit.

[0022] In some embodiments, the bottom of the main unit and the bottom of the auxiliary unit are respectively provided with anti-slip parts.

[0023] In some embodiments, the anti-slip portion is a strip-shaped protrusion;

[0024] Alternatively, the anti-slip portion may be spaced-apart dot-shaped protrusions.

[0025] The technical advantages of this application are as follows: By combining the powerful functions of a dual-screen device, the portability of the folded form, and the ease of operation of the self-supporting structure through a dual-screen design and a unique folding design, the dual-screen handheld barcode scanner can be combined into one thickened single-screen handheld barcode scanner in the folded state, which greatly reduces the overall size and space occupied by the device. This not only makes it convenient for the operator to hold the device for barcode scanning, but also makes it easy to carry in a pocket or tool bag. The self-supporting structure of the device in the unfolded state allows the device to stand upright on a flat surface, and it is convenient for the operator and the customer to view and operate the device at the same time, effectively overcoming the defects of poor scene adaptability and inconvenient interaction in the prior art.

[0039] Furthermore, in the description of this application, ordinal numbers, such as "first" and "second," are used only to distinguish related objects and should not be construed as indicating or implying the relative importance or order between related objects.

[0040] like Figures 1 to 3As shown, in one or more embodiments, this disclosure provides a dual-screen handheld barcode scanner, including a main unit 100, a secondary unit 200, and a rotating mechanism 300. The main unit 100 has a main screen 110 on its front; the secondary unit 200 has a secondary screen 210 on its front; the top of the secondary unit 200 is rotatably connected to the top of the main unit 100 through the rotating mechanism 300, so that the dual-screen handheld barcode scanner has a folded state and an unfolded state; in the folded state, the secondary unit 200 is stacked on the back of the main unit 100; in the unfolded state, the secondary unit 200 and the main unit 100 form an angle, and the bottom of the secondary unit 200 and the main unit 100 together form a support structure, so that the dual-screen handheld barcode scanner can stand upright on a plane, and the main screen 110 is set away from the secondary unit 200, and the secondary screen 210 is set away from the main unit 100.

[0041] Specifically, the main unit 100 and the secondary unit 200 are two independent modules, each equipped with a display screen. The display screen on the main unit 100 is the main screen 110, and the display screen on the secondary unit 200 is the secondary screen 210. The main screen 110 is for operator use, displaying operation menus, product lists, management interfaces, or for scanning confirmation, etc. The secondary screen 210 is for customer use, displaying payment amounts, QR codes, confirmation information, or other content that needs to be displayed. Since the secondary unit 200 is an independent module, its secondary screen 210 can be made larger, for example, filling the entire front of the secondary unit 200, to increase the size of the secondary screen 210 and display richer and clearer information, thereby improving the customer's user experience. The main unit 100 and the secondary unit 200 are electrically connected via flexible cables to ensure stable, high-speed, and interference-free power and data signal transmission, ensuring the timeliness and accuracy of the content displayed on the secondary screen 210.

[0042] The top of the secondary unit 200 is connected to the top of the main unit 100 via a rotating mechanism 300. The secondary unit 200 can rotate around the rotating mechanism 300, allowing the dual-screen handheld barcode scanner to switch between a folded and an unfolded state. In the folded state, the secondary unit 200 rotates around the rotating mechanism toward the back of the main unit 100, causing it to fit snugly against the back of the main unit 100. At this time, the dual-screen handheld barcode scanner has a compact overall shape, similar to a thickened single-screen handheld barcode scanner. In the unfolded state, the secondary unit 200 rotates in the opposite direction from the back of the main unit 100 around the rotating mechanism 300, forming an angle between the secondary unit 200 and the main unit 100. At this time, the bottom of the main unit 100 and the bottom of the secondary unit 200 together form a support structure, allowing the dual-screen handheld barcode scanner to stand stably on a table or other flat surface. At this time, both the main screen 110 and the secondary screen 210 face outwards. The main screen 110 can face the operator, and the secondary screen 210 can face the customer, achieving a complete separation of operation and display in physical space and visually.

[0043] In this embodiment, a unique folding design allows the dual-screen handheld barcode scanner to be folded into a single, thickened single-screen handheld barcode scanner, significantly reducing the overall size and space occupied. This not only makes it convenient for the operator to hold the device while scanning but also makes it easy to carry in a pocket or tool bag. The self-supporting structure in the unfolded state allows the device to stand upright on a flat surface, freeing the operator's hands for other tasks. Furthermore, by changing the angle between the secondary and primary units, it can adapt to different desktop heights and viewing angles, improving the user experience.

[0044] In some embodiments, in the folded state, the secondary screen 210 is positioned away from the main unit 100; that is, when the secondary unit 200 is stacked on the back of the main unit 100, the secondary screen 210 is located on the outside of the secondary unit 200. Since the secondary screen 210 is located on the outside of the secondary unit 200 in both the folded and unfolded states, when the dual-screen handheld barcode scanner switches between the folded and unfolded states, the secondary unit 200 only needs to rotate outward around the rotating mechanism 300 without needing to perform a flipping motion, which simplifies the structure of the rotating mechanism.

[0045] In other embodiments, in the folded state, the secondary screen 210 is positioned close to the main unit 100. That is, when the secondary unit 200 is stacked on the back of the main unit 100, the secondary screen 210 is located inside the secondary unit 200, which protects the secondary screen 210 from damage during carrying or use. Since the secondary screen 210 is located inside the secondary unit 200 in the folded state and outside the secondary unit 200 in the unfolded state, the rotating mechanism 300 needs to achieve a complex composite motion for the secondary unit 200. When the device switches from the folded state to the unfolded state, the secondary unit 200 first rotates outward around the top of the main unit 100, then flips 180 degrees around an axis, ultimately causing the secondary screen 210 to face outward in the unfolded state for easy viewing by the customer. In other words, the rotating mechanism 300 needs at least two mutually perpendicular rotating axes to achieve the rotation and flipping motion of the secondary unit 200.

[0046] In some embodiments, such as Figure 1 and Figure 2As shown, the top rear end of the main unit 100 has a protruding connecting portion 120, and the top rear end of the auxiliary unit 200 has a mounting groove 220. The connecting portion 120 is accommodated within the mounting groove 220 and is rotatably connected to the auxiliary unit 200 via a rotating mechanism 300. The connecting portion 120 protrudes from the top rear end of the main unit 100 and serves as a fixed end for the rotating mechanism 300, facilitating the installation connection between the rotating mechanism 300 and the main unit 100. Correspondingly, the top rear end of the auxiliary unit 200 has a mounting groove 220, the size and shape of which are adapted to the connecting portion 120 on the main unit 100, allowing the connecting portion 120 to be accommodated within the mounting groove 220.

[0047] One end of the rotating mechanism 300 is fixedly connected to the side wall of the mounting groove 220, and the other end of the rotating mechanism 300 is fixedly connected to the connecting part 120, thereby realizing the connection of the main unit 100 and the auxiliary unit 200 into one unit through the rotating mechanism 300, and the main unit 100 and the auxiliary unit 200 can rotate relative to each other through the rotating mechanism 300.

[0048] In this embodiment, by providing a connecting part 120 in the main unit 100, the installation of the rotating mechanism 300 can be facilitated; by installing the connecting part 120 in the mounting slot of the sub-unit 200, not only can external space be saved, but the enclosure of the connecting part 120 by the mounting slot 220 can improve the connection stability between the main unit 100 and the sub-unit 200 and avoid the feeling of shaking.

[0049] Furthermore, the top surface of the connecting part 120 is flush with the top surface of the host 100, forming a mounting plane; the scanning terminal 130 on the host 100 is disposed on the mounting plane. The top surface of the connecting part 120 and the top surface of the host 100 together form a continuous and smooth mounting plane. This mounting plane is relatively large, which facilitates the installation of the scanning terminal 130. The scanning terminal 130 is a barcode scanning module, including an optical lens and sensors, etc. The scanning terminal is embedded inside the mounting plane, and the scanning window of the scanning terminal is opened on the mounting plane.

[0050] In this embodiment, the scanning dock 130 is installed on the top surface of the connecting part 120 and the main unit 100, which can prevent the scanning dock 130 from occupying more space in the main unit 100, so that more space can be left for the battery or motherboard without changing the size of the main unit 100. The scanning dock 130 is integrated into the mounting plane, which avoids multiple discontinuous protrusions on the top of the main unit 100, so that the top of the main unit 100 forms a clean, neat and uniform outline, which greatly enhances the product's refinement and premium feel.

[0051] Furthermore, a limiting part is provided within the mounting groove 220, which cooperates with the connecting part 120 to limit the relative rotation angle between the sub-unit 200 and the main unit 100. The limiting part can be a rigid stop block provided on the inner wall of the mounting groove 220, which limits the relative rotation angle between the main unit 100 and the sub-unit 200. Alternatively, the limiting part can be a limiting groove provided on the inner wall of the mounting groove 220, and a limiting post can be provided on the connecting part 120. The limiting post slides within the limiting groove, and rotation is terminated when it reaches both ends of the limiting groove. The cooperation between the limiting post and the limiting groove effectively limits the relative rotation angle between the main unit 100 and the sub-unit 200.

[0052] When the auxiliary unit 200 is unfolded from the folded state, the connecting part 120 of the main unit 100 rotates relative to the mounting slot 220 of the auxiliary unit 200. When it rotates to the preset maximum unfolding angle (for example, the maximum unfolding angle is 120°), the connecting part 120 or the limiting post on the connecting part 120 just abuts against the limiting part. Due to physical interference, the rotation is forcibly stopped, so that the auxiliary unit 200 and the main unit 100 are maintained at the maximum unfolding angle, thereby improving the stability of the equipment in the unfolded state.

[0053] In this embodiment, the limiting part provides a clear and definite endpoint for the user's unfolding action. When rotated to the limit position, the user will feel a clear resistance, which not only improves the convenience of operation, but also ensures that each unfolding can automatically stop at the optimal, preset support angle, ensuring that the secondary screen 210 can always face the customer with the best viewing angle without the need for manual fine-tuning by the user.

[0054] In some embodiments, such as Figure 1 As shown, the rotating mechanism 300 is a damped rotating shaft. The auxiliary unit 200 is rotatably connected to the main unit 100 via the damped rotating shaft, allowing the auxiliary unit 200 to be fixed at any angle. The damped rotating shaft enables stepless angle adjustment, allowing users to steplessly and precisely adjust the auxiliary screen 210 to any ideal viewing angle based on desktop height, sitting or standing posture, their own height, or the viewing position of customers. The damping force of the damped rotating shaft ensures the stability of the posture of the main unit 100 and the auxiliary unit 200, preventing them from wobbling due to slight vibrations of the desktop.

[0055] like Figure 4 As shown, the damping shaft includes a bushing 310 and a shaft 320. One end of the bushing 310 is fixedly connected to the auxiliary machine 200, and the other end of the bushing 310 is provided with a mounting hole 311. One end of the shaft 320 is fixedly connected to the main machine 100, and the other end of the shaft 320 is inserted into the mounting hole 311 and is interference-fitted with the mounting hole 311. The damping shaft achieves damped rotation through the friction between the shaft 320 and the bushing 310.

[0056] One end of the bushing 310 has a bolt hole, and the bushing 310 is fixedly connected to the auxiliary machine 200 by bolts, etc. The other end of the bushing 310 has a mounting hole 311, the inner diameter of which is designed to be slightly smaller than the outer diameter of the rotating shaft 320. The rotating shaft 320 is a shaft-shaped component. One end of the rotating shaft 320 is fixedly connected to the main machine 100 by bolts, and the other end of the rotating shaft 320 is forced into the mounting hole 311 of the bushing 310, so that the rotating shaft 320 and the bushing 310 form an interference fit. When rotating the auxiliary machine 200, the friction between the rotating shaft 320 and the bushing 310 needs to be overcome. The rotation process is characterized by a smooth and resistant damping sensation. Once the external force is stopped, the friction is immediately restored, which is sufficient to support the weight of the auxiliary machine 200 and the main machine 100, and can be hovered at any angle.

[0057] It is understood that the rotating mechanism 300 in this embodiment is not limited to the specific form of a damping shaft, but can also be a meshing gear set, a damping hinge, or other rotating connection structure that can achieve the same function.

[0058] In some embodiments, such as Figure 1 As shown, it also includes cameras 400, with cameras 400 respectively located on the front of the main unit 100 and the front of the secondary unit 200. The camera 400 of the main unit 100 is integrated into the front of the main unit 100, typically located above, to the side of, or integrated with the main screen 110 (under-screen camera), and can be used for photographing product barcodes, performing facial recognition login, or conducting video conferencing. The camera 400 of the secondary unit 200 is integrated into the front of the secondary unit 200, and its position is also coordinated with the secondary screen 210. It can be used to collect customer facial information for payment verification (facial recognition payment), scan the payment code on the customer's mobile phone, or conduct remote video inquiries and communication with customer service. The two cameras 400 face different directions and can be activated simultaneously to capture images from two different perspectives.

[0059] In some embodiments, the bottom ends of the main unit 100 and the sub-unit 200 are respectively provided with anti-slip portions. The anti-slip portions are either strip-shaped protrusions or spaced-apart dot-shaped protrusions. When the main unit 100 and the sub-unit 200 are in the unfolded state, the anti-slip portions on the bottom of the main unit 100 and the sub-unit 200 together form a support point in contact with the tabletop. The anti-slip portions can cover the entire bottom end surface, or they can be designed as multiple discrete, symmetrically distributed anti-slip points or anti-slip strips. The material of the anti-slip portions can be a high-friction coefficient elastic material, such as silicone, rubber, or thermoplastic elastomers.

[0060] The anti-slip part can be fixed to the bottom of the main unit 100 and the auxiliary unit 200 by secondary injection molding or attachment, or by physical processing directly on the housing of the main unit 100 and the auxiliary unit 200 to form dense corrugated protrusions, serrated patterns or tiny particle textures, thereby increasing friction and achieving a better anti-slip effect.

[0061] In this embodiment, the friction provided by the anti-slip part can effectively prevent the device from sliding or tipping over due to slight vibration of the desktop or unintentional touch by the user, thereby improving the stability of the device in the unfolded state.

[0062] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0063] It should be noted that the above embodiments can be freely combined as needed. The above description is only a preferred embodiment of this application. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the protection scope of this application.
