Technical field

[0001] The present invention relates to the technical field of underwater lighting lamps, in particular a diving lamp, in which a base and a cover together form a sealed housing and enclose a mounting space to accommodate a light source and a battery. The present invention relates to a mechanical and electrical arrangement for securely fixing the battery and the conductive connection of the negative terminal, comprising a mounting plate that serves to fix and lock the battery in the base and interacts with the connection point for the negative current conductor. The embodiments of the present disclosure are suitable for an LED light source mounted on a control board, which is arranged in the mounting space and optically coupled via the light-transmitting window of the cover.The present technical field also includes common sealing and ergonomic interfaces for diving lights, such as the screw connection between the base and the lid with an intermediate sealing ring, as well as the non-slip structure on the side walls for easier handling and operation. State of the art

[0002] Diving lights are used for underwater auxiliary lighting and typically feature a sealed housing comprising a base and a cover. Together, these enclose a mounting space to house a light source, a control board, and a battery, and usually have a hinged design to facilitate battery replacement. In practical applications, such products must strike a balance between water resistance and serviceability. They are suitable for use in aquatic environments such as swimming pools, bathrooms, etc., and are subject to design limitations regarding accessibility, handling, and operation.

[0003] In many traditional designs, however, the battery is simply placed inside the housing. Once children open the housing, they can remove the battery without tools, posing safety risks such as swallowing. This reveals significant shortcomings in the child safety design of existing dive lights. Although the hinged housing design offers practical advantages, the aforementioned problem remains. Therefore, there is an urgent need for a specialized battery retention system that securely and stably holds the battery even when the lid is open.

[0004] Although the hinged housing structure offers practical advantages, the aforementioned problem remains. Therefore, there is an urgent need for a specialized battery retention system that securely and stably holds the battery even when the lid is open. Furthermore, sealing and ergonomic measures are commonly employed in this technical field, such as the screw connection between the base and the lid with an interposed sealing ring, as well as the non-slip surface on the side walls. These elements also limit how the battery retention and the arrangement of the electrical connections can be implemented within the compact diving lamp housing. Content of the invention

[0005] The object of the present invention is to overcome the shortcomings of the prior art and to provide a diving lamp to solve the technical problem of existing diving lamps with safety risks.

[0006] To achieve the above-mentioned purpose, the invention offers the following technical solutions: A diving lamp according to an embodiment of the present invention comprises the following: a base, a lid tightly connected to the base, wherein the base and the lid together enclose a mounting space in which a light source and a battery for supplying power to the light source are arranged; A mounting plate is arranged on the top of the battery, both ends of which are connected to the base and which serves to firmly fix the battery in the base.

[0007] A mounting groove with an opening is provided on the inner wall of the base, and the mounting plate bridges the edges of the mounting groove along the diameter direction of the opening.

[0008] The inner wall of the mounting groove has a slotted hole, the side wall opposite the slotted hole is provided with a threaded hole, one end of the mounting plate is inserted into the slotted hole, and the other end is screwed into the threaded hole via a screw.

[0009] The mounting plate features a raised connection point for the negative current conductor.

[0010] The connection point for the negative current line is spring-loaded and connected to the main body of the mounting plate.

[0011] The light source is positioned between the mounting plate and the lid, and a light-transmitting window is provided in the lid.

[0012] The light source comprises a control board (PCB) and an LED lamp connected to the control board, the control board also having a contact plate for electrical connection to the connection point for the negative current line.

[0013] The light-transmitting window is a lens structure that improves the light range.

[0014] The base and the lid are attached by screw connection, and a sealing ring is arranged at the screw connection point between the base and the lid.

[0015] The side walls of the base and the lid each have a non-slip structure.

[0016] The diving lamp according to the present invention secures the battery in the mounting groove of the base via a mounting plate arranged on the base. Even when the base and cover are opened, the battery remains securely fixed. Simultaneously, the diving lamp allows for a conductive connection of the negative current lead between the battery and the circuit board (PCB) without the need to solder an additional negative lead plate to the top of the circuit board, thus saving manufacturing costs. This design prevents safety hazards such as small children swallowing the battery due to it becoming detached or falling out. Its fixing structure is simple and complies with child safety standards in Europe and the USA.

Furthermore, the described specific features, structures, materials, or properties may be combined appropriately in one or more embodiments or examples. The diving lamp (100) is an ambient light for supplementary illumination during underwater work.It generally comprises a housing, a light source (3), a control board (31), and a battery (5) arranged inside the housing. The housing is usually designed as a hinged structure to allow opening and replacement of the battery, etc. However, in existing designs, the battery (5) is simply located inside the housing. If children open the housing, the battery (5) can be removed and played with without the use of tools, which could cause safety accidents such as ingestion. Therefore, existing designs of diving lamps present safety risks. Due to the above requirements, the present embodiment provides a diving lamp (100) with which the safety risks caused by the battery can be reduced.

[0026] As in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 to Fig. As shown in Figure 7, the diving lamp (100) provided by the present embodiment is suitable for supplementary lighting in underwater working environments. The diving lamp (100) comprises the following: a base (2), a cover (1) tightly connected to the base (2), wherein the base (2) and the cover (1) together enclose a mounting space (10) in which a light source (3) and a battery (5) for supplying power to the light source (3) are arranged.

[0027] To prevent the battery (5) from coming loose and falling when the cover (1) and the base (2) are opened, a retaining plate (4) is arranged on the top of the battery (5). The two opposite ends of the retaining plate (4) are both connected to the base (2), so that the retaining plate (4) fixes and locks the battery (5) in the base (2).

[0028] In the present embodiment, the battery (5) is securely held in the mounting groove (20) of the base (2) by means of the mounting plate (4). When the cover (1) and the base (2) are opened, the battery (5) remains fixed to the base (2) and does not detach or fall out, thus preventing safety hazards. When the battery (5) needs to be replaced, this must be done by adults using specialized tools, preventing children from easily opening it and creating a risk of swallowing.

[0029] As in Fig. 5, Fig. 6 to Fig. As shown again in Figure 7, a mounting groove (20) with an upper opening is provided in the base (2). The mounting plate (4) bridges the edges of the mounting groove (20) along the diameter direction of the upper opening. In particular, the mounting groove (20) is a cylindrical chamber with an upper opening. The battery (5) is installed into the mounting groove (20) through this upper opening and, after installation, is secured from above by the mounting plate (4).

[0030] The inner wall of the mounting groove (20) has a slot (23), and the side wall opposite the slot (23) is provided with a threaded hole (24). One end of the mounting plate (4) is inserted into the slot (23), and the other end is screwed into the threaded hole (24) via a screw (7). During assembly, first one end of the mounting plate (4) is inserted into the slot (23), then the screw (7) is inserted through the other end of the mounting plate (4), and finally the screw (7) is screwed into the threaded hole (24) – thus completing the fixing of the battery (5) by the mounting plate (4).

[0031] As in Fig. As shown in Figure 6, a raised connection contact point for the negative current line (41) is provided on the mounting plate (4). Therefore, no additional control board (PCB) needs to be placed on the top of the battery (5), which simplifies the structure.

[0032] The connection point for the negative current line (41) serves to provide the light source (3) with a negative contact and is accordingly electrically connected to the negative terminal of the battery (5). Since the mounting plate (4) is located directly above the battery (5), the connection point for the negative current line (41) on the mounting plate (4) preferably corresponds to the polarity of the negative terminal of the battery (5) below.The power supply circuit of the light source (3) comprises the following: a conductor which forms a negative circuit via the connection contact point for the negative power line (41) on the mounting plate (4), and another conductor via which the other electrode of the battery (5) is electrically connected to the other conductive contact of the control board (31) via a separate positive contact plate (9) or a conductor embedded in the base (2); an insulating separation is provided between the mounting plate (4) and the battery (5) by an insulating plate (8).

[0033] To improve the stability of the electrical connection between the negative current contact point (41) and the light source (3), the negative current contact point (41) is spring-loaded to the main body of the mounting plate (4). A perforated structure can be provided between the negative current contact point (41) and the main body of the mounting plate (4), or the negative current contact point (41) can be made of an elastic and conductive material to achieve the required contact pressure.

[0034] As in Fig. As shown in Figure 5, the light source (3) is arranged between the mounting plate (4) and the cover (1). A light-transmitting window (11) is provided in the cover (1), wherein the light-transmitting window (11) is a lens structure that improves the light range.

[0035] As in Fig. As shown in Figure 6, the light source (3) comprises a control board (31) and an LED lamp (32) connected to the control board (31). The control board (31) also has a contact plate or an electrical connection for the electrical connection to the terminal for the negative current line (41) (not shown in the figure). The control board (31) serves to control the battery (5) that powers the LED lamp (32) and can receive external control signals to control the switching on or off of the LED lamp (32). If the battery (5) is a rechargeable and dischargeable battery, the control board (31) also has a charge and discharge management function. In this embodiment, the battery (5) is a button cell or several button cells connected in series. Specifically, the base (2) is screwed to the cover (1), and a sealing ring (6) is provided at the screw connection point.The base (2) is provided with an external thread (22); correspondingly, the cover (1) is equipped with an internal thread. Both are screwed together and fixed by turning.

[0036] As in Fig. As shown in Figure 3, a first non-slip structure (21) is provided on the side wall of the base (2) and a second non-slip structure (13) is provided on the side wall of the lid (1). This makes it easier for the user to open the lid (1) and the base (2) by turning; at the same time, the first non-slip structure (21) and the second non-slip structure (13) can also increase the heat dissipation area to improve heat dissipation efficiency.

[0037] In a representative embodiment, the base (2) and the cover (1) together form a sealed housing and define a mounting space (10). The mounting plate (4) extends transversely along the diameter direction of the upper opening of the mounting groove (20) to counteract the upward displacement of the battery (5) when the housing is opened and serviced. This ensures that the battery (5) remains securely fixed even when the cover (1) and base (2) are open, thus eliminating the safety risk associated with tool-free removal of the battery.

[0038] The mounting plate (4) combines mechanical fixing and electrical functions: it supports the raised connection contact point for the negative current line (41) above the battery (5) and simultaneously secures the battery (5) firmly in the base (2); the spring connection between the connection contact point for the negative current line (41) and the mounting plate (4) helps to maintain a reliable contact pressure and stable negative conductivity even under vibration and shock conditions.

[0039] During assembly, first one end of the mounting plate (4) is inserted into the slot (23) on the side wall of the mounting groove (20). Then, a screw (7) is inserted through the other end of the mounting plate (4) and screwed into the threaded hole (24) on the opposite side wall to secure the battery (5). Maintenance is performed in reverse order. A tool is required to remove the screw (7), thus preventing unauthorized access by children and reducing the risk of accidental removal of the battery (5).

[0040] The insulating plate (8) is positioned between the mounting plate (4) and the battery (5) to prevent a short circuit and to ensure that the intended negative path is formed exclusively via the connection point for the negative current line (41). Other conductive areas remain electrically isolated from the battery housing, allowing the mounting plate (4) to exert mechanical pressure while maintaining circuit integrity.

[0041] The light source (3) is positioned between the mounting plate (4) and the cover (1), and the translucent window (11) provided in the cover (1) improves the light range by acting as a lens. The control board (31) and the LED lamp (32) are arranged in the mounting space (10), which promotes optical coupling relative to the translucent window (11) and simultaneously ensures a compact package around the mounting groove (20).

[0042] To ensure immersion performance, the base (2) is screwed to the cover (1), at the screw connection of which a sealing ring (6) is provided. The base (2) has an external thread (22), and the cover (1) has a corresponding internal thread – both achieve a tight connection through the application of torque. The first anti-slip surface (21) and the second anti-slip surface (13) facilitate the application of the opening or closing torque and simultaneously improve thermal management performance by increasing the surface area. Regarding the power supply architecture, the negative path is routed via the contact point for the negative power line (41) on the mounting plate (4), while the positive path is connected to the corresponding conductive contacts of the control board (31) via the separate positive contact plate (9) or a line integrated into the base (2).The control board (31) can receive external control signals to control the switching on and off of the LED lamp (32) and performs the charging and discharging management of a rechargeable and dischargeable battery (5).

[0043] In an exemplary implementation, the battery (5) is a button cell or several button cells connected in series to meet the voltage requirements of the control board (31) and the LED lamp (32) without increasing the footprint of the mounting slot (20). The mounting plate (4) and the connection point for the negative current line (41) ensure electrical continuity in the series configuration, and the insulating plate (8) provides the necessary electrical insulation protection.

[0044] The features described in connection with any embodiment (e.g., the resilient connection of the terminal contact point for the negative current line (41), the interaction of the plug hole (23) / threaded hole (24) / screw (7), the sealing ring (6), and the anti-slip structures (21, 13)) can be combined in any suitable way, provided they are not mutually exclusive. This allows for the realization of various embodiments within the scope of the claims. The accompanying drawings are schematic and not necessarily to scale. The relative relationships between the elements can be adapted in practice, while maintaining the structural and functional relationships mentioned above.

[0045] The structure described above allows the battery (5) to be securely fixed even when the cover (1) is open. At the same time, this eliminates the need for a separate negative contact plate on the top of the control board (31), simplifying the components and reducing manufacturing costs. Furthermore, the diving light (100) reduces the risk of the battery (5) coming loose and being swallowed by children. The fixing structure is simple in design and complies with European and American safety standards for use by children.

[0046] The dimensions, contours and tolerances of the base (2), the cover (1), the mounting space (10) and the mounting groove (20) can be selected according to the target requirements for mechanical fixation, watertightness and operating characteristics - provided that the mounting plate (4) continues to be laid transversely along the diameter direction of the upper opening of the mounting groove (20) to secure the battery (5) in the base (2).

[0047] The thickness and shape of the mounting plate (4) can be adjusted as needed to achieve a balance between stiffness and local flexibility in the area of ​​the connection point for the negative current line (41). At the same time, electrical insulation is maintained by the insulating plate (8) arranged between the mounting plate (4) and the battery (5).

[0048] The interaction between the mounting plate (4) and the base (2) via the slotted hole (23), the threaded hole (24), and the screw (7) can be configured as required. This ensures protection against disassembly and vibration resistance in underwater environments for the consumer market, while maintaining serviceability for adults who can replace the battery (5) using specialized tools.

[0049] The connection contact point for the negative current line (41) can either have a segmented structure (including hole structure) with a spring connection to the mounting plate (4) to ensure contact pressure, or be made of an elastic and conductive contact material to ensure a stable electrical connection to the light source (3).

[0050] The energy path to the light source (3) comprises a first circuit via the connection contact point for the negative current line (41) and a second circuit via the separate positive contact plate (9) or the integrated line. The arrangement of both circuits in the mounting space (10) can be optimized as needed to reduce contact resistance and prevent interference with the optical components.

[0051] The translucent window (11) of the cover (1) acts as a lens to improve the light range. Depending on the number and distribution of the LED lamps (32) on the control board (31), the lens geometry and position can be selected to simultaneously adjust the light cone angle and the light intensity distribution while maintaining the lens function.

[0052] The sealing ring (6) provided at the screw connection between the base (2) and the cover (1) can achieve the target compression volume according to the assembly torque. The dimensional ratio between the external thread structure (22) and the corresponding internal thread structure ensures reliable sealing at the desired hydrostatic pressure.

[0053] The first non-slip structure (21) and the second non-slip structure (13) can have surface textures with increased friction while increasing the exposed area to aid heat dissipation, as shown in the accompanying drawings.

[0054] The battery (5) can be a single button cell or several button cells connected in series, the number of cells connected in series being determined according to the voltage requirements of the control board (31) and the LED lamp (32). When using a rechargeable and dischargeable battery, the control board (31) performs the corresponding charging and discharging management as well as the on / off control.

[0055] The assembly and maintenance can be carried out in the following sequence: The battery (5) is placed in the mounting groove (20), one end of the mounting plate (4) is inserted into the slot (23), the screw (7) is guided through the other end of the mounting plate (4) and finally screwed into the threaded hole (24). This ensures that the battery (5) remains fixed in the base (2) even when the cover (1) is removed, thanks to the mounting plate (4) which runs across the mounting groove (20), thus maintaining child safety.

[0056] The diving lamp (100) of the present embodiment secures the battery (5) in the mounting groove (20) via the mounting plate (4) arranged on the base (2). Even when the base (2) and the cover (1) are opened, the battery (5) remains securely fixed. Simultaneously, the electrical connection of the negative current line between the mounting plate (4) and the control board (31) eliminates the need for additional soldering of a negative conductor plate on the top of the control board (31), thus reducing manufacturing costs. This design prevents accidental damage in which the battery (5) becomes detached and falls out, potentially being accidentally swallowed by small children. The fixing structure is simple and complies with European and American safety standards for children's use.The above descriptions merely illustrate the technical content of the present invention by means of embodiments to facilitate the reader's understanding, without implying that the embodiments of the present invention are limited to them. Any technical extension or innovation based on the present invention is protected by the present invention; the scope of protection of the present invention is governed by the claims.
