Abstract
Description
Technical Field
[0001] This invention relates to the field of optical instruments, and more specifically to a power supply module for an optical instrument. Background Technology
[0002] Optical instruments generally require a power supply module. For civilian portable optical instruments, such as laser levels, batteries are generally used for power supply. The power is supplied to the laser module through a circuit board. Battery power is convenient for replacement and carrying. Such optical instruments are generally equipped with a battery compartment, and the battery compartment of optical instruments is generally accessed from the end.
[0003] In existing technologies, the power supply module of optical instruments is designed for compactness. Typically, one end of the battery compartment is used for battery installation and removal, while the other end directly abuts against the circuit board. Corresponding conductive contacts are set on the circuit board to connect with the battery end for power supply. This design can greatly optimize the internal space of the optical instrument. However, the battery needs a certain contact pressure to conduct electricity. The battery installation and removal end of the battery compartment needs to be equipped with an elastic structure. As a result, the pressure generated at the contact point between the battery and the circuit board can easily cause the circuit board to deform. Furthermore, when used outdoors and carried, laser levels are prone to collisions and drops, which can exacerbate the deformation. The battery installation and removal end of the battery compartment also needs to be equipped with an elastic contact component, which also causes inconvenience in opening and closing this end. Utility Model Content
[0004] The purpose of this invention is to provide a power supply module for optical instruments, which solves the problem of existing batteries causing circuit board deformation when they are in contact with the circuit board.
[0005] The present invention achieves the above objectives through the following technical solutions: A power supply module for an optical instrument includes a cover and a power supply compartment for accommodating a power source. A conductive part is mounted on the cover, wherein the conductive part includes an elastic contact part for pressing against the power source and a conductive contact part extending through the outside of the cover for supplying power to the optical instrument.
[0006] As a preferred embodiment of this utility model, the power compartment is provided with an assembly base, the cover fits into the opening of the power compartment, and the cover is provided with an assembly hole. The assembly hole and the assembly base are connected by a fastener. In this embodiment, the cover has sufficient thickness due to the opening of multiple T-shaped grooves, and is further connected to the power compartment by two fasteners, which are respectively set at both ends of the cover.
[0007] As a preferred embodiment of this utility model, the conductive part further includes a mounting part. A T-shaped groove is provided in the cover body. The mounting part is connected to the large end of the T-shaped groove. The small end of the T-shaped groove is used to extend the elastic contact part into the power supply compartment. This solution connects the conductive part to the cover body by opening a T-shaped groove on the cover body and using an internal fitting method. It has considerable firmness, and the cover body is not easily deformed. Moreover, the cover body is integrally formed, which is suitable for assembly with the conductive part during the production process.
[0008] As a preferred embodiment of this utility model, a connecting groove is provided on the side of the cover, and the conductive contact part extends through the connecting groove to the outside of the cover. This embodiment allows the conductive contact part to directly extend to the outside of the cover by providing a connecting groove, which facilitates power supply to the power-consuming parts of optical instruments.
[0009] In a preferred embodiment of this utility model, the mounting part is a conductive body with a bent part thereon. The bent part abuts against the T-shaped groove, which is used to make the mounting part move unidirectionally in the assembly direction within the T-shaped groove. By tilting the bent part, the mounting part can only be assembled within the T-shaped groove, thus preventing it from moving out.
[0010] As a preferred embodiment of this utility model, the power source in the power compartment is a battery, and a conductive structure is provided at the end of the power compartment away from the cover to make the battery ends electrically connected to each other. In this embodiment, the battery is installed and removed from the other end of the power compartment, and both elastic contact parts are provided on the cover to facilitate the opening and closing of the battery cover at the other end of the power compartment.
[0011] As a preferred embodiment of this utility model, there are two batteries arranged side by side in the power compartment, and two conductive parts are provided on the cover. This embodiment uses two batteries for power supply, and the positive and negative terminals are reversed, with two corresponding conductive parts.
[0012] The beneficial effects of the present invention are as follows: by dividing the conductive part into an installation part, an elastic contact part, and a conductive contact part, it is convenient to install and supply power to the outside. Moreover, the elastic force fed back by the elastic contact part is spread on the cover through multiple installation parts, which avoids the deformation of the circuit board and remains firm and stable under heavy drops and impacts.

[0014] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.
[0015] Example 1 like Figure 1-5 As shown, a power supply module for an optical instrument includes a cover 1 and a power supply compartment 2 for accommodating a power source. A conductive part 3 is mounted on the cover 1. The conductive part 3 includes an elastic contact part 34 for pressing against the power source and a conductive contact part 32 that extends to the outside of the cover 1 for supplying power to the optical instrument.
[0016] This design divides the conductive part 3 into an installation part 31, an elastic contact part 34, and a conductive contact part 32, which facilitates installation and external power supply. In use, the conductive part 3 is installed into the cover 1, and the conductive contact part 32 extends to the outside of the cover 1 and is connected to the circuit board through a conductive wire or electric contact. The elastic force fed back by the elastic contact part 34 is distributed on the cover 1 through multiple installation parts 31, which avoids the deformation of the circuit board and ensures that it remains firm and the contacts are stable even under heavy drops and impacts.
[0017] Preferably, the power compartment 2 is provided with a mounting base 21, the cover 1 fits into the opening of the power compartment 2, and the cover 1 is provided with a mounting hole 11. The mounting hole 11 and the mounting base 21 are connected by a fastener 4. In this embodiment, the cover 1 is provided with multiple T-shaped grooves, has sufficient thickness, and is further connected to the power compartment 2 by two fasteners 4, which are respectively provided at both ends of the cover 1.
[0018] Specifically, the conductive part 3 also includes a mounting part 31. A T-shaped groove 12 is provided in the cover 1. The mounting part 31 is connected to the large end of the T-shaped groove 12. The small end of the T-shaped groove 12 is used to extend the elastic contact part 34 into the power supply compartment 2. By opening a T-shaped groove on the cover 1, the conductive part 3 is connected to the cover 1 through internal fitting, which has considerable firmness. The cover 1 is not easily deformed. The cover 1 is integrally formed, which is suitable for assembly with the conductive part 3 during the production process. As a preferred solution, the cover 1 can be set to an ellipse, or it can be set to a square, circle or other combined shapes.
[0019] Preferably, a connecting groove 13 is provided on the side of the cover 1, and the conductive contact part 32 extends through the connecting groove 13 to the outside of the cover 1. By providing the connecting groove, the conductive contact part 32 can directly extend to the outside of the cover 1, which facilitates power supply to the power supply parts of optical instruments. In order to reduce weight and save materials, the mounting part 31 can be set to a hollow shape.
[0020] As another preferred embodiment, please refer to Figure 3-5 The mounting part 31 is a conductive body with a bent part 33 on it. The bent part 33 abuts against the T-shaped groove 12, which is used to allow the mounting part 31 to move unidirectionally in the assembly direction within the T-shaped groove 12. By setting this shape, the mounting part 31 can directly enter the T-shaped groove 12, which is simple to assemble and has a strong structure. Specifically, the mounting part 31 is a flat conductive body with bent parts 33 on both sides. The angle of the bent part 33 is preferably 45°, which is used to press against the T-shaped groove 12 after entering the T-shaped groove 12 to prevent it from retracting.
[0021] Preferably, the power source in the power compartment 2 is a battery, and the end of the power compartment 2 away from the cover 1 is provided with a conductive structure to electrically connect the battery ends to each other. The battery is a common portable power supply component. In this embodiment, the battery is installed and removed from the other end of the power compartment 2 away from the cover 1, and both elastic contact parts 34 are provided on the cover 1 to facilitate the opening and closing of the battery cover at the other end of the power compartment 2. It should be noted that although both elastic contact parts 34 are provided on the cover 1 in this embodiment, the positive and negative terminals of the battery are still reversed. A conductive sheet is provided on the battery cover at the other end of the power compartment 2 to connect the positive and negative terminals of the battery. The elastic contact part 34 can be a spring, elastic sheet, or other components.
[0022] Preferably, there are two batteries arranged side by side in the power compartment 2, and two conductive parts 3 are provided on the cover 1. The power is supplied by two batteries, and there are two corresponding conductive parts.
[0023] Please see Figure 3 During production and assembly, the cover 1 is integrally formed, and the conductive part 3 is assembled into it. The conductive contact part 32 enters the connecting groove 13 through the T-shaped groove 12, while the mounting part 31 enters the T-shaped groove 12 and is locked by the bending part 33 to restrict the retraction of the mounting part 31 and to press the mounting part 31. The elastic contact part 34 extends into the power compartment 2. The cover 1 is connected to the mounting base 21 by the fastener 4. Then the switch and wires of the optical instrument are connected to the two conductive contacts 32. Finally, when in use, the battery is inserted into the power compartment 2.
[0024] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
