Description

Technical Field

[0001] This utility model relates to the field of mobile lighting technology, and in particular to a flashlight with a dust cover. Background Technology

[0002] Currently, most rechargeable portable lights (such as flashlights) on the market use a sealing plug as a dustproof structure, requiring users to manually pull or insert the sealing plug from the charging port. This structure has two drawbacks: first, the connection between the sealing plug and the housing is usually quite weak; improper force during insertion or removal can easily tear or break the connection, affecting the sealing effect and lifespan; second, manually inserting the sealing plug is inconvenient for elderly users or those with poor eyesight. To address these issues, some have invented structures with assisted dustproof covers. For example, Chinese utility model patent CN222824207U discloses a portable lighting lamp with an assisted dustproof cover. This lamp features a protrusion at the rotating end of the dustproof cover, allowing the assistive top block and assistive spring to provide assistance when rotating to open or close the cover, making it easier for users to operate. However, this solution has the following problems: First, it requires a screw and a shaft to install the fixing block and dust cover respectively, which not only makes the structure more complicated, but also requires multiple holes for installation, increasing the risk of water entering the lamp cavity; Second, the dust cover and the booster block are positioned by using a beveled fit, which cannot form a stable positioning angle, and the dust cover is easy to shake after it is opened. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a flashlight with a simpler structure, more reasonable design, reduced risk of water ingress into the inner cavity, and more stable charging port with an auxiliary dust cover after the dust cover is opened.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a flashlight with a charging port and a dust cover, comprising a shell, a lamp body, a battery, a charging interface, and a dust cover assembly. The dust cover assembly includes a dust cover, a positioning head, and an elastic component. The fixing head of the dust cover is pivotally mounted in the mounting groove of the shell via a pin. The positioning head is movably disposed in the mounting groove and docks with the fixing head of the dust cover through the cooperation of the elastic component. A first positioning groove and a second positioning groove in the shape of a recessed groove are provided along the side of the fixing head, and the two positioning grooves are separated by a protruding transition portion. A positioning part is provided on the top of the positioning head, which can engage with the first positioning groove and the second positioning groove respectively. When the dust cover is on, the positioning part engages and locks with the first positioning groove. When the dust cover is open, the positioning part engages and locks with the second positioning groove.

[0005] Preferably, the first positioning groove and the second positioning groove have the same size, both of which are arc-shaped grooves or V-shaped grooves, and the positioning part is the arc-shaped part or V-shaped part corresponding to the two positioning grooves.

[0006] Furthermore, the opening direction of the first positioning groove is perpendicular to the opening direction of the second positioning groove, and the positioning part is located in the middle position of the positioning head.

[0007] Preferably, the transition portion is a convex arc-shaped structure or a V-shaped structure.

[0008] Furthermore, the dustproof assembly also includes a fixing seat, which is fixed in the mounting groove of the housing. The fixing head of the dustproof cover is embedded in the fixing seat, and the shaft pin passes through the shaft hole of the fixing seat and the fixing head to achieve pivotal fixing of the dustproof cover.

[0009] Furthermore, a thread is provided near the end of the shaft pin, which is screwed into the threaded hole of the housing to install and fix the fixing seat, while the fixing head is inserted on the part of the shaft pin that is not threaded.

[0010] Preferably, the elastic part is a spring, and there is one spring, which holds the positioning head against the positioning head.

[0011] Preferably, the charging interface is a waterproof TYPE-C interface or MICRO-USB interface, and a sealing ring is provided between the charging interface and the housing for sealing.

[0012] This invention has the following advantages over existing technologies: First, by setting a screw on the shaft pin for screwing and fixing it to the housing, and simultaneously pivotally connecting the dust cover to the fixing base, a dual-purpose shaft is achieved. This eliminates the need for an additional screw mounting base, simplifying the installation structure and reducing the number of openings in the housing, thus lowering the risk of water ingress. Second, by setting two positioning grooves on the fixing head of the dust cover, and positioning parts on the positioning head that can engage with the two positioning grooves respectively, the positioning heads can stably lock into the corresponding positioning grooves when the dust cover is closed or opened, resulting in less wobbling and greater stability after opening. Furthermore, only a spring is needed to hold the positioning head in place, further simplifying the structure. Attached Figure Description

Detailed Implementation

[0020] In this embodiment, refer to Figures 1-6 The flashlight with a charging port and dust cover includes a housing 1, a lamp body 2, a battery 5, a charging interface 4, and a dustproof assembly. The dustproof assembly includes a dust cover 3, a positioning head 33, and an elastic component. The fixing head 31 of the dust cover 3 is pivotally mounted in the mounting groove 12 of the housing 1 through a shaft pin 34 passing through the shaft hole 311 of the fixing head 31. The positioning head 33 is movably disposed in the mounting groove 12 and mates with the fixing head 31 of the dust cover 3 through the cooperation of the elastic component. The charging interface 4 is installed in the housing and connected to the circuit components inside the housing 1. The housing 1 is also provided with a switch button 6 for control. The light is switched on and off and in different modes; a first positioning groove 312 and a second positioning groove 313 in the shape of a recessed groove are provided along the side of the fixing head 31, and the two positioning grooves are separated by a protruding transition part 314; a positioning part 331 is provided on the top of the positioning head 33, which can engage with the first positioning groove 312 and the second positioning groove 313 respectively. When the dust cover 3 is closed, the positioning part 331 and the first positioning groove 313 are engaged and locked together, and the charging interface 4 is covered at this time; when the dust cover 3 is opened, the positioning part 331 and the second positioning groove 313 are engaged and locked together, and the dust cover 3 is raised to expose the charging interface 4.

[0021] The first positioning groove 312 and the second positioning groove 313 have the same size, and both are arc-shaped grooves (or V-shaped grooves). The positioning part 331 is an arc-shaped part (or V-shaped part) corresponding to the two positioning grooves. When opening or closing the dust cover 3, after the fixing head 31 rotates until the transition part 314 passes the positioning part 331, the fixing head 31 will continue to rotate under the action of the elastic component through the positioning head 33 until the positioning part 331 is engaged in the next positioning groove (for example, switching from the first positioning groove 312 to the second positioning groove 313 when opening the dust cover 3). Due to the matching curvature, the dust cover 3 can maintain a stable state whether it is open or closed, and it is not easy to shake.

[0022] The opening direction of the first positioning groove 312 is perpendicular to the opening direction of the second positioning groove 313. The positioning part 331 is located in the middle of the positioning head 33. The dust cover 3 is basically in a vertical state after it is opened.

[0023] The transition portion 314 is a protruding arc-shaped structure (or a V-shaped structure) so that it can pass over the positioning portion 331 more smoothly.

[0024] The dustproof assembly also includes a fixing seat 32, which is fixed in the mounting groove 12 of the housing 1. The fixing head 31 of the dustproof cover 3 is embedded in the fixing seat 32. The shaft pin 34 passes through the shaft hole 311 of the fixing seat 32 and the fixing head 31 to achieve pivotal fixing of the dustproof cover 3.

[0025] A thread is provided near the end of the shaft pin 34, which is screwed into the threaded hole of the housing 1 to install and fix the fixing seat 32. The fixing head 31 is inserted into the unthreaded part of the shaft pin. In this way, only one shaft is needed to install and fix the fixing seat 32 and the dust cover 3 at the same time, thereby reducing the number of holes that need to be drilled in the housing due to multiple shafts (or screws), thus reducing the risk of water entering the inner cavity 11 of the housing 1 through the holes.

[0026] The elastic part uses a single spring 35, which holds the positioning head 33 in place. This design is simpler than the existing technology that uses two springs, reduces costs, and makes assembly easier.

[0027] The charging port 4 uses a waterproof TYPE-C interface (or MICRO-USB interface). A sealing ring is provided between the charging port 4 and the housing 1, which can be used with the dust cover 31 to achieve an IPX67 waterproof rating.

[0028] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
