Description

Technical Field

[0001] This application relates to the technical field of barcode scanners, and more specifically, to a barcode scanner light effect display structure. Background Technology

[0002] A barcode scanner is a device that quickly inputs information from barcodes, QR codes, and other similar documents by scanning. Existing barcode scanners typically have a light display area on the casing, such as on the top, to indicate successful scanning. However, this single-light display area results in a small display area and a limited display effect, failing to meet users' needs for simultaneously displaying diverse information such as the scanner's battery level and scan confirmation. Utility Model Content

[0003] To address the aforementioned shortcomings of the prior art, this application provides a barcode scanner light effect display structure that sets different light display areas to separately display battery level and barcode confirmation light effects.

[0004] To solve the above-mentioned technical problems, the technical solution adopted in this application is: a barcode scanner light effect display structure, which includes a housing located at the upper end of the barcode scanner, one end of the housing is a scanning end, and the other end is provided with a light shield bracket. A light PCB board is provided on the side of the light shield bracket facing the inside of the housing. At least a first light-transmitting hole and a second light-transmitting hole are provided on the light shield bracket. A first light guide and a second light guide are respectively provided in the first light-transmitting hole and the second light-transmitting hole. The areas where the first light guide and the second light guide are located respectively form a first light display area and a second light display area.

[0005] With the above structure, this application forms at least two light display areas, a first light display area and a second light display area, on the side of the barcode scanner housing closest to the user. These two light display areas can be used to display indicators such as the barcode scanner's battery level and the barcode confirmation light effect, respectively. Therefore, compared with the existing single display, this structure allows the user to simultaneously obtain the battery level and barcode confirmation information while observing the position of the light display area on the barcode scanner housing. Observation is convenient and quick. This structure can meet the need to obtain multiple light effect results by observing the same part. Moreover, both light display areas are located on the barcode scanner housing closer to the user's observation end rather than on the top, making it more convenient for the user to quickly observe and obtain the displayed information.

[0006] Furthermore, the first light guide is used to display the battery level, and a light display area for displaying the remaining battery level of the barcode scanner can be formed on the housing of the barcode scanner.

[0007] Furthermore, the second light guide is used to display the scanning confirmation light effect; a light area for displaying the scanning confirmation light effect can be formed on the housing of the barcode scanner. By observing the position of this light display area on the housing of the barcode scanner, information on the power display of the barcode scanner and the display of the scanning confirmation light effect can be obtained simultaneously.

[0008] Furthermore, the first light guide is a hollow cylinder located at the upper part of the light-shielding bracket. The first light guide is a cylindrical light guide column that matches the first light-transmitting hole. With this structure, users can obtain the barcode scanner's battery information more quickly. Moreover, three such cylindrical first light guides can be set and arranged side by side along the horizontal direction of the light-shielding bracket. The number of lights emitted by the three first light guides can be used to determine the barcode scanner's battery level, thus assessing whether the barcode scanner needs to be charged and its usage time.

[0009] Furthermore, the outer wall of the light-shielding bracket is provided with a groove at the first light-transmitting hole, and a light-diffusing film is provided in the groove, which covers the outside of the first light guide. This structure can improve the light emission uniformity of the light guide and also improve the display effect of the light, reducing the impact on the user's vision.

[0010] Furthermore, the second light-transmitting hole is located at the lower part of the light-shielding bracket, and the second light guide includes an inner light guide strip and an outer light guide strip connected together. The inner light guide strip is located inside the second light-transmitting hole, and the outer light guide strip is snapped onto the side of the light-shielding bracket facing the interior of the housing. With this structure, the second light-transmitting hole and the first light-transmitting hole are arranged vertically on the light-shielding bracket, which is convenient for user observation. Moreover, the second light guide is designed with inner and outer light guide strips, which also facilitates its assembly with the light-shielding bracket to utilize the light extraction.

[0011] Furthermore, the outer contour of the inner light guide strip is smaller than that of the outer light guide strip, and a stepped surface is formed at the connection between the inner and outer light guide strips; a retaining ring that abuts against the stepped surface is provided on the inner surface of the light shield bracket along the outer periphery of the second light-transmitting hole, and the stepped surface abuts against the retaining ring; with this structure, the second light guide can be limited on the light shield bracket by the stepped surface, and the outer light guide strip is located inside the light shield bracket, while the inner light guide strip is inserted into the second light-transmitting hole to realize the extraction of light.

[0012] Furthermore, a semi-transparent cover plate is provided on the outer surface of the light-shielding bracket on the side away from the light PCB board; this structure can create a screen-off effect when the barcode scanner is not in use.

[0013] Furthermore, the translucent cover plate has a buckle and a guide post on its surface facing the light-shielding bracket, and the corresponding light-shielding bracket has a slot and a guide hole. The buckle engages with the slot, and the guide post is fitted into the guide hole. With this structure, the translucent cover plate and the light-shielding bracket can be fastened together to cover the first light display area and the second light display area to achieve a screen-off effect.

The terminology used herein in the description of this invention is for the purpose of describing particular, specific embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] As attached Figure 1-12As shown, this application discloses a lighting effect display structure. The structure includes a housing 1 located at the top of a barcode scanner. One end of the housing 1 is a barcode scanner 101, and the other end is provided with a light-shielding bracket 2. A light PCB board 3 is provided on the side of the light-shielding bracket 2 facing the interior of the housing 1. The light-shielding bracket 2 is provided with at least a first light-transmitting hole 4 and a second light-transmitting hole 5. The first light-transmitting hole 4 and the second light-transmitting hole 5 are used for light emission. A first light guide 6 and a second light guide 7 are respectively provided in the first light-transmitting hole 4 and the second light guide 7. The areas where the first light guide 6 and the second light guide 7 are located respectively form a first lighting display area S1 and a second lighting display area S2. Specifically, the end of the housing 1 closest to the information waiting to be scanned, such as the barcode or QR code, is the barcode scanner, and the opposite end forms the end for user observation. This end is closer to the user, making it more convenient for the user to observe the lighting display area.

[0030] With the above structure, this application forms at least two light display areas, a first light display area S1 and a second light display area S2, on the side of the barcode scanner housing 1 closest to the user. These two light display areas can be used to display indicators such as the barcode scanner's battery level and the barcode confirmation light effect. Therefore, compared with the existing single display, this structure allows the user to simultaneously obtain the battery level and barcode confirmation information when observing this position of the barcode scanner housing 1, making observation convenient and quick. This structure can meet the need to obtain multiple light effect results by observing the same part. By setting the light-shielding bracket 2, this application ensures that light can only be emitted from the light-transmitting hole, and the light is confined to a specific area, thus facilitating user observation. Moreover, both light display areas are located on the side of the barcode scanner housing 1 closest to the user's observation end rather than on the top. During the barcode scanning process, this position directly faces the user, making it easier for the user to quickly observe and obtain the display information of the two lights.

[0031] As an example, the first light guide 6 described in this application is used to display the barcode scanner's battery level, and the second light guide 7 is used to display the barcode scanning confirmation lighting effect. That is, the light intensity of the first light guide 6 indicates the remaining battery level of the barcode scanner. After the barcode scanner's scanning end 101 scans a QR code or barcode, it checks whether the information has been successfully acquired by the barcode scanner. If it has, the second light guide 7 emits light to indicate successful acquisition. With this structure, the battery level display and the barcode scanning confirmation lighting effect can be obtained simultaneously by observing the positions of these two light display areas on the barcode scanner's housing 1.

[0032] As attached Figure 5-6As shown, the first light-transmitting hole 4 described in this application is a hollow cylinder and is located at the upper part of the light-shielding bracket 2. The first light guide 6 is a cylindrical light guide column that matches the first light-transmitting hole 4. That is, in this application, the first light guide 6 can be sleeved in the first light-transmitting hole 4, and then the light is emitted from the light PCB board 3 and led out from one end of the first light guide 6 along the axis and emitted from the other end of the axis to form a light spot to display the battery level of the barcode scanner.

[0033] More specifically, as shown in the appendix Figure 1 , Figure 5-6 and Figure 9 As shown, the first light guide 6 described in this application is provided with three lines arranged side by side along the transverse direction of the light shield bracket 2. With this structure, users can obtain the barcode scanner's battery information more quickly. Moreover, the number of light-emitting elements of the three first light guides 6 arranged side by side along the transverse direction of the light shield bracket 2 can be used to determine the barcode scanner's battery level, thus providing an assessment of whether the barcode scanner needs charging and its usage time.

[0034] More specifically, as shown in the appendix Figure 5-6 As shown, the first light guide 6 of the cylindrical light guide column described in this application extends axially in the same direction as the thickness extension of the light shield 2. The light guide can be fixed in the first light-transmitting hole 4 by bonding or interference fit. With this structure, the user can observe three light-emitting dots, which can be effectively distinguished from the second light guide 7, quickly determine the remaining power of the barcode scanner, and does not require occupying too much area of ​​the light shield 2.

[0035] As attached Figure 1 , 3 , Figure 5-6 As shown, the outer wall of the light-shielding bracket 2 described in this application is provided with a recessed groove 201 at the first light-transmitting hole 4. A light-diffusing film 8 is provided in the recessed groove 201, and the light-diffusing film 8 covers the outside of the first light guide 6. Specifically, the light-diffusing film 8 covers the first light guide 6 near the user's observation end. With this structure, the light emission uniformity of the light guide can be improved, and the display effect of the light can also be improved, reducing the impact on the user's vision.

[0036] As attached Figure 7-8 and Figure 9As shown, the second light-transmitting hole 5 described in this application is located at the lower part of the light-shielding bracket 2; the second light guide 7 includes an inner light guide strip 701 and an outer light guide strip 702 connected to each other. The inner light guide strip 701 is located inside the second light-transmitting hole 5, and the outer light guide strip 702 is snapped onto the side of the light-shielding bracket 2 facing the inside of the housing 1. With this structure, the second light-transmitting hole 5 and the first light-transmitting hole 4 are arranged in an upper and lower position on the light-shielding bracket 2, which is convenient for user observation; and the second light guide 7 is configured as an inner and outer light guide strip, wherein the outer contour of the inner light guide strip 701 matches the inner contour of the second light-transmitting hole 5. After the two are fitted together, light is introduced from the outer light guide strip 702 side to the inner light guide strip 701 side. This structure of the light guide is also convenient to be assembled with the light-shielding bracket 2 to utilize the light extraction.

[0037] As attached Figure 7-8 and Figure 9 As shown, the outer contour of the inner light guide 701 is smaller than the outer contour of the outer light guide 702. A stepped surface 703 is formed at the connection between the inner light guide 701 and the outer light guide 702. A retaining ring 202 is provided on the inner surface of the light shield 2 along the outer periphery of the second light-transmitting hole 5, which abuts against the stepped surface 703. The stepped surface 703 abuts against the retaining ring 202. With this structure, the second light guide 7 can be limited on the light shield 2 by the stepped surface 703, and the outer light guide 702 is located on the inner side of the light shield 2, that is, the side close to the light PCB board 3, while the inner light guide 701 is inserted into the second light-transmitting hole 5 to realize the extraction of light.

[0038] More specifically, as shown in the appendix Figure 1 , Figure 3 and Figure 7-8 As shown, the inner light guide 701 and outer light guide 702 described in this application are elongated and extend along the width direction of the light shield 2, that is, along the left and right lateral directions of the light shield 2. The second light guide 7 is located at the end of the light shield 2 away from the first light guide 6, that is, the second light guide 7 and the first light guide 6 are located above and below the light shield 2. With this structure, an elongated barcode scanner scanning light effect display can be formed, increasing the display area, making it convenient for users to observe, and also making it easy to effectively distinguish from the first light guide 6 for power display, so as not to be confused. The first light guide 6 and the second light guide 7 are arranged above and below the light shield 2, and the two light display areas are reasonably distributed on the shell of the barcode scanner near the user side, so that the user can observe the display information of the two light effects at the same time. The inner light guide 701 is inserted into the second light-transmitting hole 5 and is close to the user's observation end.

[0039] As an example, the colors of the lights drawn out by the first light guide 6 and the second light guide 7 described in this application may be different; by adopting this scheme, it is easier for users to quickly distinguish and judge the lighting effect display information corresponding to the first light guide 6 and the second light guide 7 respectively.

[0040] As attached Figure 4-6 As shown, the outer surface of the light-shielding bracket 2 on the side away from the light PCB board 3 described in this application is covered with a semi-transparent cover plate 9. With this structure, a screen-off effect can be formed when the barcode scanner is not in use. The semi-transparent setting does not affect the transmission of light in the first light display area S1 and the second light display area S2. Specifically, the semi-transparent cover plate 9 can be a black semi-transparent cover plate 9, which can achieve a more ideal screen-off effect.

[0041] As attached Figure 6 , Figure 9-10 As shown, the translucent cover plate 9 of this application has a buckle 901 and a guide post 902 on its surface facing the light-shielding bracket 2. The corresponding light-shielding bracket 2 has a slot 203 and a guide hole 204. The buckle 901 is engaged with the slot 203, and the guide post 902 is fitted into the guide hole 204. Specifically, the buckle 901 and the guide post 902 of this application are respectively located near the left and right sides in the width direction of the light-shielding bracket 2, and are flush in height. During assembly, the guide post 902 and the guide hole 204 can be engaged and inserted first, and then the buckle 901 can be inserted into the slot 203 to achieve connection. With this structure, the translucent cover plate 9 and the light-shielding bracket 2 can be engaged and connected, covering the first light display area S1 and the second light display area S2 to achieve the screen-off effect.

[0042] As attached Figure 2 and Figure 6 As shown, the light-shielding bracket 2 described in this application also has a snap-fit ​​structure on the inner surface of the side near the light PCB board 3, through which the light-shielding bracket 2 and the light PCB board 3 are fastened together.

[0043] As attached Figure 11-12 As shown, this application includes a barcode scanner with the aforementioned lighting effect display structure. When the user observes the location of the housing where the two lighting display areas are set on the barcode scanner, the user can simultaneously obtain power display information and scan confirmation lighting effect display information, so as to facilitate the user to judge the scanning effect and the remaining power of the barcode scanner.

[0044] The barcode scanner's lighting display structure of this application sets different light display areas on the scanner's housing near the user's observation end to display the scanner's battery level and the scanning confirmation lighting effect, respectively. Thus, the user can simultaneously obtain two lighting effect display information by observing this part of the housing. This lighting display structure of this application sets a light-shielding bracket 2 and a light-diffusing film 8 on the light-shielding bracket 2 to guide the light emission area and direction, and will not cause irritation to the user's eyes, making the light softer.
