Abstract
Description
Technical Field
[0001] This utility model relates to the field of infrared imaging technology, and in particular to a battery compartment structure and an infrared thermal imaging device. Background Technology
[0002] Infrared thermal imaging equipment, such as infrared thermal imaging telescopes, is a device that uses infrared thermal imaging technology for long-distance observation. It can convert the invisible infrared energy emitted by a target object into a visible thermal image, thereby enabling long-distance imaging and temperature measurement of the target's thermal state. There are two main power supply methods for infrared thermal imaging telescopes: built-in battery power and external battery power. When using external battery power, a common single-cell lithium battery is typically placed in a battery compartment within the telescope's casing. To ensure stable power supply and a robust casing structure, the casing and battery compartment of commercially available infrared thermal imaging telescopes are usually integrally molded. Specifically, magnesium alloy or aluminum alloy is generally used to integrally mold the casing and battery compartment. Furthermore, to simplify the structural design, the battery is often integrated into the casing as part of the negative electrode, reducing the need for additional negative leads and lowering production costs. However, when the infrared thermal imaging device is subjected to external impact, the battery compartment cover may momentarily disconnect from the battery compartment due to vibration, leading to a power outage and affecting the normal operation of the infrared thermal imaging device. Therefore, ensuring a stable power supply from the battery to the infrared thermal imaging device when subjected to external impact is a critical technical problem that needs to be solved.

[0048] like Figure 1-7As shown, in one embodiment of this utility model, a battery compartment structure includes a main shell 10 and a battery compartment reinforcement 20. A battery compartment 11 is disposed within the main shell 10. The battery compartment 11 has two ends: one end is an open end 111, and the other opposite end is a closed end 110. The closed end 110 is provided with a first electrode 12 for electrical connection with a battery 50 installed within the battery compartment 11. The battery compartment reinforcement 20 is installed at the open end 111 of the battery compartment 11, and the battery compartment reinforcement 20 is provided with... The mounting part is used to connect and install the battery compartment cover 30. The conductivity of the material of the battery compartment reinforcement 20 is greater than that of the material of the main shell 10. The opening end 111 is provided with a first protrusion 14 protruding from the inner wall of the battery compartment 11. The connecting section 21 is provided with a second protrusion 210 protruding from the outer wall of the battery compartment reinforcement 20. The first protrusion 14 and the second protrusion 210 are connected by interlocking so that the battery compartment reinforcement 20 is installed in the opening end 111 of the battery compartment 11.
[0049] In existing designs, the battery compartment cover of infrared thermal imaging equipment is connected to the battery compartment via threads (the inner thread of the cover engages with the outer thread of the compartment). This battery compartment cover is a critical component in the current path during equipment operation. However, when the equipment is subjected to external impact, the resulting strong vibration may cause a momentary loosening between the battery compartment cover and the battery compartment. This loosening causes the threads to lose effective contact momentarily, leading to a momentary interruption of the current path. Consequently, the infrared thermal imaging equipment malfunctions due to an unexpected momentary interruption of battery power.
[0050] In this application's technical solution, a battery compartment reinforcement 20 is added between the battery compartment 11 and the battery compartment cover 30. The opening end 111 of the battery compartment 11 is provided with a first protrusion 14 protruding from the inner wall of the battery compartment 11. The battery compartment reinforcement 20 includes a connecting section 21 and an extension section 22. The extension section 22 is provided with a mounting part for connecting and installing the battery compartment cover, that is, the battery compartment cover 30 is first securely and tightly connected to the battery compartment reinforcement 20 (e.g., snap-fit connection). The connecting section 21 is provided with a second protrusion 210 protruding from the outer wall of the battery compartment reinforcement 20, and the battery compartment 11 and the battery compartment reinforcement 20 are connected by interlocking between the two protrusions. The interlocking connection (meaning that when the connecting section 21 of the battery compartment reinforcement 20 is inserted into the opening end 111 of the battery compartment 11, the two protrusions are interference-fitted and squeeze each other during connection, resulting in local plastic deformation at the squeezing point, and the local plastic deformation points of the two form a nested interlocking connection) forms an extremely strong mechanical interlock. Even when the infrared thermal imaging device is subjected to external impact, the connection between the battery compartment 11 and the battery compartment reinforcement 20 is stable, and the battery compartment cover 30 is firmly and tightly connected to the battery compartment reinforcement 20, which can always ensure that the power supply circuit of the infrared thermal imaging device is always unobstructed, and the battery can stably supply power to the infrared thermal imaging device.
[0051] In addition, in the above scheme, the battery compartment structure adopts a split configuration, which is divided into a main shell 10 and a battery compartment reinforcement 20. The main shell 10 is integrally formed with the body shell 40, and the conductivity of the material of the battery compartment reinforcement 20 is greater than that of the main shell 10. This can reduce the overall impedance of the body shell 40, make fuller use of the battery's electrical energy, reduce the loss of electrical energy during transmission, and thus extend the battery's power supply time. This allows the infrared thermal imaging telescope to have a longer working time and better meet the needs of long-term use.
[0052] like Figure 1-7 As shown, in one embodiment of this utility model, the battery compartment reinforcement 20 includes a connecting section 21 and an extension section 22. The connecting section 21 is provided with a second protrusion 210 protruding from the outer wall of the battery compartment reinforcement 20, and the opening end 111 is provided with a first protrusion 14 protruding from the inner wall of the battery compartment 11. The battery compartment reinforcement 20 and the main shell 10 have the first protrusion 14 and the second protrusion 210, and the first protrusion 14 and the second protrusion 210 are connected by an interference fit through riveting, so as to achieve a stable electrical connection between the battery compartment reinforcement 20 and the main shell 10, and avoid the battery compartment reinforcement 20 and the main shell 10 from separating and losing power after being impacted during product use, which would affect the user experience of the product.
[0053] like Figure 1-7As shown, in one embodiment of this utility model, the inner wall of the battery compartment 11 is circular, the outer wall of the connecting section 21 is cylindrical, the length of the first protrusion 14 extends along the axial direction of the battery compartment 11, and the length of the second protrusion 210 extends along the circumferential direction of the connecting section 21. In other embodiments, the length of the first protrusion 14 may also extend along the circumferential direction of the battery compartment 11, and the second protrusion 210 may extend along the axial direction of the connecting section 21. The first protrusion 14 and the second protrusion 210 are arranged perpendicular to each other, and the first protrusion 14 and the second protrusion 210 are connected by an interference fit riveting connection. Furthermore, the first protrusion 14 includes multiple sets, and the second protrusion 210 includes multiple sets. The multiple sets of the first protrusion 14 and the multiple sets of the second protrusion 210 are arranged in a one-to-one correspondence. The multiple sets of engagement can provide more contact points and greater friction, thereby better dispersing and bearing external forces, further improving the impact resistance of the battery compartment structure and the stability of the electrical connection between the battery compartment reinforcement 20 and the main shell 10.
[0054] like Figure 1-7 As shown, in one embodiment of this utility model, a first positioning protrusion 211 is provided on the outer wall of the connecting section 21, and a second positioning protrusion (not shown) is provided on the inner wall of the opening end 111. The first positioning protrusion 211 and the second positioning protrusion abut against each other to limit the relative rotational movement of the battery compartment reinforcement 20 and the main shell 10, thereby fixing the dwell angle of the battery compartment reinforcement 20 at the opening end 111, so as to ensure the uniformity of the subsequent battery compartment cover 30 installation direction.
[0055] like Figure 1-7 As shown, in one embodiment of this utility model, an installation groove 212 is provided on the outer wall of the connection between the connecting section 21 and the extension section 22. A sealing element 213 is installed in the installation groove 212. The sealing element 213 can seal the gap between the battery compartment reinforcement 20 and the opening end 111, thus providing waterproofing and dustproofing. This helps protect the battery 50 and related components inside the battery compartment 11, preventing moisture and dust from entering and causing short circuits, corrosion, and other problems, thereby extending the service life of the battery compartment structure and improving the reliability and durability of the product.
[0056] like Figure 1-7As shown, in one embodiment of this utility model, the mounting part includes a first snap-fit part 220 disposed on the outer wall of the extension section 22, and a second snap-fit part 31 disposed inside the battery compartment cover 30. The battery compartment cover 30 is stably installed on the battery compartment reinforcement 20 by snap-fit connection between the first snap-fit part 220 and the second snap-fit part 31. Furthermore, in one embodiment of this utility model, the battery compartment cover 30 is sleeved on the outside of the battery compartment reinforcement 20, and the battery compartment cover 30 is provided with a second electrode 13 for electrical connection with the battery 50 installed in the battery compartment 11. This snap-fit connection method is simple and convenient to operate. The user only needs to twist the battery compartment cover 30 in the forward direction to achieve the snap-fit connection and complete the installation, while twisting in the reverse direction can make the battery compartment cover 30 disengage from the mounting part, easily realizing the switching between the lock and open states of the battery compartment cover 30. This design not only facilitates the installation and removal of the battery compartment cover 30 by the user, but also improves the efficiency of battery 50 replacement and enhances the user experience.
[0057] In one embodiment of this utility model, the main shell 10 is made of magnesium alloy or aluminum alloy, and the battery compartment reinforcement 20 is made of copper or copper alloy. That is, the hardness and conductivity of the material of the battery compartment reinforcement 20 are greater than those of the main shell 10. Using copper or copper alloy to make the battery compartment reinforcement 20 results in high surface hardness, and it is not easy to shed lint after long-term disassembly and reassembly with the battery compartment cover 30. This can prevent lint from causing a short circuit between the positive and negative terminals of the battery and burning out the battery. In addition, the battery compartment reinforcement 20 is not easily oxidized, which could lead to an insulation short circuit.
[0058] like Figure 1-7 As shown, in one embodiment of the present invention, the connecting segment 21 is provided with a stop ring groove 214 at one end near the opening end 111, and the inner wall of the opening end 111 is provided with a stop protrusion 15 embedded in the stop ring groove 214, and the stop protrusion 15 abuts against the second protrusion 210. The stop protrusion 15 restricts the extension length of the connecting segment 21 in the opening end 111, and the stop protrusion 15 abuts against the second protrusion 210, further improving the stability of the electrical connection between the battery compartment reinforcement 20 and the main shell 10.
[0059] An infrared thermal imaging device includes a battery compartment structure as described in any of the preceding claims and a housing 40, wherein the battery compartment structure is disposed on the housing 40. The aforementioned battery compartment structure improves energy utilization efficiency by reducing impedance. The interlocking connection ensures a tighter electrical connection between the battery compartment reinforcement 20 and the main housing 10, effectively resisting external interference and ensuring the stability of the battery compartment structure under various complex operating environments, especially under vibration and shock conditions. The sealing element 213 (which may be a sealing ring) seals the gap between the battery compartment reinforcement 20 and the opening end 111, providing waterproofing and dustproofing. This helps protect the battery and related components inside the battery compartment, preventing moisture and dust from entering and causing short circuits, corrosion, and other problems, thereby extending the service life of the battery compartment structure and improving product reliability and durability. Through the snap-fit connection structure, the user can easily achieve the snap-fit connection and complete the installation by simply twisting the battery compartment cover 30 in the forward direction, while twisting in the reverse direction allows the battery compartment cover 30 to detach from the mounting part, easily switching the battery compartment cover 30 between the lock and open states. This design not only makes it easier for users to install and remove the battery compartment cover 30, but also improves the efficiency of battery replacement.
[0060] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
