Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more specifically, to a lamp. Background Technology

[0002] In the professional lighting field, work lights are a commonly used lighting tool. Currently, portable work lights are needed in many places where fixed light sources cannot be used, such as outdoor or field environments.

[0003] However, most light fixtures on the market have non-replaceable batteries, which greatly affects user experience and maintenance. Additionally, while some light fixtures do have replaceable batteries, their waterproofing is poor, easily leading to circuit damage or electric shock, causing inconvenience and even endangering lives.

[0004] Furthermore, due to their lack of waterproofing, they cannot meet user needs and have limited applicability. In particular, replaceable battery lamps cannot effectively guarantee both sealing and the requirements for quick disassembly and maintenance, presenting numerous contradictions and shortcomings that hinder their widespread adoption.

[0005] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] In view of this, the object of the present invention is to provide a lamp to solve the above problems.

[0007] The present invention adopts the following solution:

[0008] This application provides a lamp fixture, including: a lamp body and a power module; the lamp body includes a housing assembly and a light-emitting component disposed on the housing assembly; the power module includes a battery pack assembly; the housing assembly has a connecting portion suitable for engaging the light-emitting component and a mounting portion for accommodating the battery pack assembly; an internal cavity suitable for the battery pack assembly to enter and exit is formed in the mounting portion, the internal cavity is constrained at its mounting position by a cover assembly disposed on the housing assembly, and the internal cavity has an ejector assembly on the side away from the cover assembly, the ejector assembly elastically abutting against the battery pack assembly housed in the internal cavity; wherein, a sealing assembly is provided between the battery pack assembly and the internal cavity, the sealing assembly is disposed on the side away from the ejector assembly, and forms a waterproof area in the internal cavity; after the cover assembly moves to release the constraint on the battery pack assembly, the elastic force provided by the ejector assembly to the battery pack assembly is greater than the tight fit force provided by the sealing assembly to the battery pack assembly, so as to facilitate the quick removal of the battery pack assembly from the internal cavity.

[0009] As a further improvement, the ejection assembly includes a spring disposed on the inner end side of the internal chamber, and a retaining seat for defining the spring in relation to the battery pack assembly; the retaining seat is detachably disposed within the housing assembly, and the spring protrudes from the end face of the retaining seat.

[0010] As a further improvement, the spring is configured as a helical compression spring, and the inner diameter of the helical compression spring gradually decreases from the end face of the fixing seat to the end face of the battery pack assembly, so as to provide the battery pack assembly with a lateral elastic force instantaneously after it leaves the internal cavity.

[0011] As a further improvement, the sealing assembly includes a waterproof ring disposed on the outer periphery of the battery pack assembly, the battery pack assembly having an installation groove suitable for the waterproof ring, the battery pack assembly and the internal cavity having a clearance fit, and the waterproof ring disposed on the battery pack assembly abutting against the internal cavity.

[0012] As a further improvement, the mounting groove is arranged circumferentially around the battery pack assembly and positioned on the outer end of the battery pack assembly adjacent to the inner chamber, so that the longitudinal clamping force provided by the waterproof ring to the battery pack assembly at the mounting position in the inner chamber is far removed from the elastic force provided by the ejector assembly, which is suitable for effortlessly performing the detachment operation of the battery pack assembly in the inner chamber.

[0013] As a further improvement, the cover assembly includes a bottom cover hinged to the housing assembly in an opening and closing manner, and a fastener disposed on the bottom cover; the fastener is capable of elastically locking onto the housing assembly when the bottom cover is in a closed state to prevent the battery pack assembly from popping out, and of switching the bottom cover to an open state after the fastener is operably moved to release the elastic locking.

[0014] As a further improvement, the fastening element is configured as a push-twist structure and is elastically positioned on the outer end side of the bottom cover; wherein, the inner end side of the bottom cover is provided with a buffer protruding from the end face, the buffer being able to press directly onto the battery pack assembly after the bottom cover is in the closed state, so as to provide a reaction force that cooperates with the ejection assembly.

[0015] As a further improvement, the buffer is constructed as a pad of a certain thickness, which is centrally located on the inner end face of the bottom cover to cooperate with the ejection assembly to define the installation position of the battery pack assembly in the internal chamber.

[0016] As a further improvement, a control circuit board is also included; the control circuit board is electrically connected to the light-emitting component, and the control circuit board is provided with a contact structure that can be electrically engaged with the battery pack assembly.

[0017] As a further improvement, the housing assembly includes a main housing and a sub-housing detachably mounted on the main housing; an assembly space for an internal electrical module is formed between the sub-housing and the main housing, and the connecting part is configured as a hinge seat formed by the sub-housing covering the front half of the main housing, and the internal cavity of the mounting part is formed separately in the rear half of the main housing; wherein, the light-emitting component includes a body that cooperates with the hinge seat and a strip light and a spherical light disposed on the body; the body is provided with a hinge shaft that is dampedly connected to the hinge seat, the strip light is disposed on the front end side of the body, and the spherical light is disposed on the rear end side of the body, thereby operablely switching between two modes.

[0018] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0019] 1. The lighting fixture of this application, while meeting the requirements for disassembly and maintenance of the power module in the form of a battery pack, ensures, on the one hand, that the battery pack assembly forms a waterproof zone in the internal cavity through the sealing component, so as to achieve the airtightness of the power supply in the housing after frequent disassembly and assembly, significantly improving the service life of the lighting fixture. On the other hand, the ejection component equipped in the internal cavity can directly provide the power for the battery pack assembly to quickly detach from the internal cavity after the cover assembly is released from the limit, thereby performing an ejection operation on the tightly set battery pack assembly and the outer shell assembly, which greatly facilitates the user to remove and replace it.

[0020] 2. The ejector assembly is positioned in the internal cavity away from the cover assembly to provide an elastic force for easy detachment of the battery pack assembly. The sealing assembly is positioned away from the ejector assembly to provide a tight fitting force for installation. This design not only ensures that the battery pack assembly has a large enough waterproof area within the internal cavity, but also avoids interference between the tight fitting force and the elastic force, resulting in a more efficient and labor-saving design. Furthermore, the sealing assembly has a shorter effective tight fitting force within the internal cavity. After the elastic force detaches the battery pack assembly, the tight fitting force disappears when the sealing assembly is exposed to the outside, significantly improving the efficiency of detaching and reassembling the battery pack assembly within the internal cavity and enhancing the user experience.

[0033] Example

[0034] Combination Figures 1 to 6This embodiment provides a lamp, including a lamp body 1 and a power module 2. The lamp body 1 includes a housing assembly 3 and a light-emitting component 4 disposed on the housing assembly 3. The power module 2 includes a battery pack assembly 5. The housing assembly 3 has a connecting portion suitable for engaging the light-emitting component 4 and a mounting portion for accommodating the battery pack assembly 5. An internal cavity 6 suitable for the battery pack assembly 5 to enter and exit is formed in the mounting portion. The internal cavity 6 is constrained at its mounting position by a cover assembly disposed on the housing assembly 3, and an ejector assembly 7 is provided on the side of the internal cavity 6 away from the cover assembly. The ejector assembly 7 elastically abuts against the battery pack assembly 5 housed in the internal cavity 6. A sealing assembly 8 is provided between the battery pack assembly 5 and the internal cavity 6. The sealing assembly 8 is disposed on the side away from the ejector assembly 7 and forms a waterproof area in the internal cavity 6. After the cover assembly moves to release the restriction on the battery pack assembly 5, the elastic force provided by the ejector assembly 7 to the battery pack assembly 5 is greater than the tight fitting force provided by the sealing assembly 8 to the battery pack assembly 5, so as to facilitate the quick removal of the battery pack assembly 5 from the internal chamber 6.

[0035] The aforementioned lamps, while meeting the disassembly and maintenance requirements of the power module 2 in the form of a battery pack, also ensure that the battery pack assembly 5 forms a waterproof zone in the internal cavity 6 through the sealing assembly 8, thereby achieving the airtightness of the power supply in the housing after frequent disassembly and assembly, significantly improving the service life of the lamps. On the other hand, the ejection assembly 7 equipped in the internal cavity 6 can directly provide the power for the battery pack assembly 5 to quickly detach from the internal cavity 6 after the cover assembly is released from its limiting position, thereby performing an ejection operation on the tightly set battery pack assembly 5 and the outer shell assembly 3, greatly facilitating the user to remove and replace them.

[0036] The ejector assembly 7 is positioned in the internal cavity 6, away from the cover assembly, to provide the battery pack assembly 5 with an elastic force for easy disengagement. The sealing assembly 8 is positioned away from the ejector assembly 7 to provide the battery pack assembly 5 with a tight-fitting force for installation. This arrangement not only ensures that the battery pack assembly 5 has a large enough waterproof area within the internal cavity 6, but also avoids interference between the tight-fitting force and the elastic force due to their distance from each other, resulting in a more efficient and labor-saving process. Furthermore, the sealing assembly 8 has a smaller effective tight-fitting force within the internal cavity 6. After the elastic force disengages the battery pack assembly 5, the tight-fitting force disappears when the sealing assembly 8 is exposed to the outside, significantly improving the efficiency of disassembly and assembly of the battery pack assembly 5 within and outside the internal cavity 6, and enhancing the user's operating experience.

[0037] like Figure 2 and Figure 4As shown, in one embodiment, the ejection assembly 7 includes a spring 9 disposed on the inner end side of the internal chamber 6, and a fixing seat 10 for defining the spring 9 facing the battery pack assembly 5. The fixing seat 10 is detachably disposed within the housing assembly 3, and the spring 9 protrudes from the end face of the fixing seat 10. The spring 9 is configured as a helical compression spring, and its inner diameter gradually decreases from the end face of the fixing seat 10 to the end face of the battery pack assembly 5, providing a lateral elastic force to the battery pack assembly 5 momentarily after it detaches from the internal chamber 6. Thus, the end face of the battery pack assembly 5, assembled in the internal chamber 6, presses against the spring 9, causing the spring to be in a stored state. At this time, the battery pack assembly 5 is stably defined in its installation position by the limiting position of the cover assembly, allowing the battery pack assembly 5 to perform normal charging and discharging power functions. Until the cover assembly moves to the contact limit position, the spring 9 releases its elastic potential energy, thereby ejecting the battery pack assembly 5 out of the internal chamber 6.

[0038] like Figure 2 , Figure 4 As shown, in one embodiment, the sealing assembly 8 includes a waterproof ring 11 disposed on the outer periphery of the battery pack assembly 5. The battery pack assembly 5 has a mounting groove suitable for the waterproof ring 11. The battery pack assembly 5 and the internal cavity 6 are in clearance fit, and the waterproof ring 11 disposed on the battery pack assembly 5 abuts against the internal cavity 6. The mounting groove is circumferentially arranged around the battery pack assembly 5 and disposed on the outer end of the battery pack assembly 5 adjacent to the internal cavity 6. This allows the longitudinal tightening force provided by the waterproof ring 11 to the battery pack assembly 5 at the installation position in the internal cavity 6 to be far removed from the elastic force provided by the ejector assembly 7, facilitating effortless disassembly of the battery pack assembly 5 from the internal cavity 6. In this embodiment, the waterproof ring 11, with its elastic protrusion on the outer periphery of the battery pack assembly 5, can fit tightly against the inner wall of the internal cavity 6 after assembly, improving the sealing and tightness between them. In particular, the triggering position of the elastic force and the application position of the tightening force tend to be relatively far apart, facilitating coordinated operation after disassembly and assembly, resulting in excellent effortless operation and waterproof sealing.

[0039] like Figure 1 and Figure 2As shown, in one embodiment, the cover assembly includes a bottom cover 12 hinged to the outer casing assembly 3 in an opening and closing manner, and a fastening member 13 disposed on the bottom cover 12. The fastening member 13 is capable of spring-locking onto the outer casing assembly 3 when the bottom cover 12 is in the closed state to prevent the battery pack assembly 5 from popping out, and of switching the bottom cover 12 to the open state after the fastening member 13 is operably moved to release the spring-locking. It should be noted that the fastening member 13 is configured as a push-twist structure and is spring-locked onto the outer end of the bottom cover 12. Obviously, the push-twist structure spring-locked onto the bottom cover 12 is more convenient for the user to directly press and push, correspondingly locking the bottom cover 12 onto the outer casing assembly 3 or unlocking it and rotating it away from the battery pack assembly 5, achieving the purpose of an openable / closing cover installation.

[0040] In a preferred embodiment, a buffer 14 protruding from the end face is provided on the inner end side of the bottom cover 12. The buffer 14 can press against the battery pack assembly 5 when the bottom cover 12 is in the closed state, so as to provide a reaction force that cooperates with the ejector assembly 7. Thus, after the battery pack assembly 5 is in the installed position, the spring 9 of the ejector assembly 7 and the buffer 14 are positioned opposite each other on opposite sides of the battery pack assembly 5, and the two interact and restrict each other, significantly improving the relative stability of the battery pack assembly 5 in its installed position. In particular, the buffer 14 is constructed as a thick gasket, which is centrally disposed on the inner end face of the bottom cover 12 to cooperate with the ejector assembly 7 to define the installation position of the battery pack assembly 5 in the internal cavity 6.

[0041] like Figure 2 and Figure 6 As shown, in one embodiment, a control circuit board 15 is also included. The control circuit board 15 is electrically connected to the light-emitting component 4, and the control circuit board 15 is provided with a contact structure capable of electrically engaging with the battery pack assembly 5. Thus, when the battery pack assembly 5 is positioned, the contact structure can be elastically engaged with the battery pack assembly 5, thereby achieving an electrical connection to further supply power to the light-emitting component 4.

[0042] In one embodiment, the housing assembly 3 includes a main housing 16 and a sub-housing 17 detachably disposed on the main housing 16. An assembly space for the internal electrical module is formed between the sub-housing 17 and the main housing 16, and the connecting part is configured as a hinge formed by the sub-housing 17 covering the front half of the main housing 16. The internal cavity 6 of the mounting part is separately formed in the rear half of the main housing 16. The light-emitting assembly 4 includes a body 20 that cooperates with the hinge and a strip light 18 and a spherical light 19 disposed on the body 20. The body 20 has a hinge shaft that is dampedly connected to the hinge. The strip light 18 is disposed on the front end of the body 20, and the spherical light 19 is positioned opposite the rear end of the body 20, allowing for operable switching between two modes. This assembly method between the housings greatly improves the product's recognizability and practicality. Obviously, the control circuit board 15 has a push-button switch, a charging interface, etc., which will not be described in detail here.

[0043] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
