Description

Technical Field

[0001] This utility model relates to the field of battery compartment technology, and in particular to a side-mounted waterproof battery compartment structure and sensor. Background Technology

[0002] High-protection sensors are sensors with high waterproof and dustproof ratings, enabling them to work stably in harsh environments. Generally, high-protection sensors are powered by replaceable batteries, and if the battery life is insufficient during daily use, the old batteries need to be replaced regularly.

[0003] Currently, the waterproof structure of the battery compartment of such sensors is simple. If the battery compartment is opened again, the seal of the waterproof structure is easily damaged and can no longer provide waterproofing. Therefore, the sensor after battery replacement cannot meet the waterproof requirements, nor can it provide dust protection. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a side-mounted waterproof battery compartment structure and sensor that can maintain waterproof and dustproof requirements even after the battery is replaced from the side.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] This utility model provides a side-mounted waterproof battery compartment structure, including a side cover and a housing. The housing contains a battery compartment, and the side wall of the battery compartment has an outwardly protruding side opening for placing and removing the battery. The side cover is used to close the side opening. It also includes an electrical connection assembly. The electrical connection assembly includes a conductive spring, a first electrode plate, and a spring. The spring is assembled to the spring to form an electrical connection, and the spring is assembled inside the side cover. The battery compartment has a second electrode plate for electrically connecting the inward-facing end of the battery. The first electrode plate is located on the side of the battery compartment opposite to the second electrode plate. One end of the first electrode plate passes through the side opening and abuts against the outward-facing side wall of the side opening to form an electrical connection end. A sealing ring is provided between the side cover and the side opening to form a sealing fit. When the side cover is assembled to the side opening, the spring elastically abuts against the outward-facing end of the battery, and the spring elastically abuts against the electrical connection end of the first electrode plate.

[0007] Furthermore, the spring is bowl-shaped, one end of the spring is fixed to the center of the spring, and the other end of the spring is used to elastically abut against the outward end of the battery and form an electrical connection.

[0008] Furthermore, the side cover has a protruding connecting rib at its center, the spring sheet has a central hole at its center, the connecting rib passes through the central hole and is hot-riveted to the spring sheet.

[0009] Furthermore, the inner circumferential wall of the side cover is provided with a first thread, and the outer circumferential wall of the side opening protruding outward is provided with a second thread. The first thread is screwed into the second thread so that the side cover applies pressure to the spring, thereby causing the spring to form an elastic constraint on the battery in the battery compartment to ensure a stable electrical connection.

[0010] Furthermore, it also includes a circuit board disposed within the housing, the circuit board having a first power terminal and a second power terminal for electrically connecting the battery, the first power terminal and the second power terminal of the circuit board being respectively fixedly mounted on the first electrode plate and the second electrode plate by conductive screws, and forming an electrical connection in sequence.

[0011] Furthermore, the housing includes an upper cover and a lower cover, the upper cover being ultrasonically welded to the lower cover to form a sealed configuration.

[0012] Furthermore, both the first electrode sheet and the second electrode sheet are mounted on the bottom shell.

[0013] This invention provides a sensor, which includes at least the aforementioned side-mounted waterproof battery compartment structure.

[0014] The technical solution provided by this utility model has the following beneficial effects:

[0015] By inserting the battery laterally into the battery compartment through the side opening and assembling the side cover onto the side opening, the side cover applies pressure to the spring and forms an elastic force towards the battery. At this time, the spring provides elastic restraint to the battery inside the battery compartment, that is, the spring elastically abuts against the outward end of the battery, and the spring piece electrically connected to the spring elastically abuts against the electrical connection end of the first electrode plate. This ensures a stable electrical connection between the first electrode plate and the battery. At the same time, a sealing ring is used to achieve a sealed fit between the side cover and the side opening, so as to realize the side replacement of the battery. The sealing ring is not easily damaged during disassembly and assembly, and still ensures its waterproof requirements. Attached Figure Description

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] Reference Figures 1 to 4 As shown, Embodiment 1 provides a side-mounted waterproof battery compartment structure (hereinafter referred to as the battery compartment structure). The battery compartment structure of this embodiment includes a side cover 2 and a housing 1. The housing 1 has a battery compartment 13 inside, and the side wall of the battery compartment 13 has an outwardly protruding side opening 121 for taking out and placing the battery 7. The side cover 2 is used to close the side opening 121 to seal the side opening 121. The housing 1 specifically includes an upper cover 11 and a bottom shell 12. The side opening 121 is located on one side of the bottom shell 12. The upper cover 11 is fixedly connected to the bottom shell 12 by ultrasonic welding process to form an integral whole, and at the same time, a sealed fit is achieved between the upper cover 11 and the bottom shell 12.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, the battery compartment structure of this embodiment also includes an electrical connection component 3. The electrical connection component 3 includes a conductive spring 31, a first electrode 32, and a spring 33. The spring 33 is assembled on the spring 31 to form an electrical connection. The spring 31 is assembled inside the side cover 2. The battery compartment 13 is provided with a second electrode 4 for electrically connecting the inward end of the battery 7. The first electrode 32 is provided on the side of the battery compartment 13 away from the second electrode 4. One end of the first electrode 32 passes through the side opening 121 and abuts against the outward side wall of the side opening 121 to form an electrical connection end 321.

[0026] A sealing ring 8 is provided between the side cover 2 and the side opening 121 to form a sealing fit with the side opening 121. When the side cover 2 is assembled into the side opening 121, the spring 33 is used to elastically abut against the outward end of the battery 7, and the spring piece 31 is used to elastically abut against the electrical connection end 321 of the first electrode plate 32. When the battery 7 is installed in the battery compartment 13, the first electrode plate 32 can be electrically connected to the outward end of the battery 7 through the spring piece 31 and the spring 33.

[0027] The battery compartment structure of this embodiment also includes a circuit board 5 disposed inside the housing 1. The circuit board 5 has a first power terminal and a second power terminal for electrically connecting the battery 7. The first power terminal and the second power terminal of the circuit board 5 are respectively fixedly mounted on the first electrode plate 32 and the second electrode plate 4 by two conductive screws 6, and form an electrical connection in sequence to ensure that the battery 7 can supply power to the circuit board 5 normally after installation.

[0028] In specific implementation, the spring 33 is a tower spring, the first electrode plate 32 and the second electrode plate 4 are both assembled on the screw post inside the bottom shell 12, and the first electrode plate 32 and the second electrode plate 4 correspond to the positive and negative terminals of the battery 7, respectively.

[0029] like Figure 4 As shown, the spring piece 31 is bowl-shaped, and the inner wall of the side cover 2 and the spring piece 31 are spaced apart to ensure that the spring piece 31 is smoothly installed in the side cover 2. Of course, in other embodiments, the spring piece 31 can also be square or triangular or other shapes, as long as the spring piece 31 can abut the electrical connection end 321 of the first electrode piece 32.

[0030] When it is necessary to install the spring 31 and the spring 33, the spring 31 has a central hole located in the center of the side cover 2, and the connecting rib 21 is passed through the central hole. Then the connecting rib 21 is hot-riveted to the spring 31 so that one end of the spring 33 is fixed to the center of the spring 31, and the other end of the spring 33 is used to elastically abut against the outward end of the battery 7 and form an electrical connection. This completes the assembly of the spring 33 onto the spring 31 to form a whole, and then the whole thing is installed inside the side cover 2.

[0031] When the side cover 2 needs to be installed on the housing 1, the side cover 2 is provided with a first thread on its circumferential inner wall and a second thread on its outwardly protruding outer circumferential wall of the side opening 121. The first thread is screwed into the second thread to enable the side cover 2 to be detachably installed on the housing 1. At the same time, the side cover 2 applies pressure to the spring 33, thereby causing the spring 33 to form an elastic constraint on the battery 7 in the battery compartment 13 to ensure a stable electrical connection.

[0032] When a new battery 7 needs to be installed, the battery 7 is inserted laterally into the battery compartment 13 through the side opening 121, and the side cover 2 is assembled into the side opening 121. This causes the side cover 2 to apply pressure to the spring 33 and form an elastic force towards the battery 7. At this time, the spring 33 forms an elastic constraint on the battery 7 in the battery compartment 13. That is, the spring 33 elastically abuts against the outward end of the battery 7, and the spring piece 31 electrically connected to the spring 33 elastically abuts against the electrical connection end 321 of the first electrode piece 32. This can ensure a stable electrical connection between the first electrode piece 32 and the battery 7. At the same time, the sealing ring 8 achieves a sealing fit between the side cover 2 and the side opening 121 to realize the lateral replacement of the battery 7. The sealing ring 8 is not easily damaged during disassembly and assembly, and can still ensure its waterproof requirements, and of course, it also meets the dustproof requirements.

[0033] In this embodiment, the battery compartment structure can ensure waterproofing and dustproofing while also allowing the battery 7 to conduct electricity and supply power to the circuit board 5, even with frequent battery replacements.

[0034] Of course, in other embodiments, the installation between the side cover 2 and the housing 1 can also be achieved by a fastening method such as a snap-fit ​​structure.

[0035] Example 2

[0036] like Figure 5 As shown, Embodiment 2 provides a sensor, which includes at least the side-mounted waterproof battery compartment structure of Embodiment 1, and the side cover 2 is assembled on one side of the housing 1.

[0037] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
