Abstract
Description
Technical Field
[0001] This utility model relates to the field of power supply stability, and in particular to a battery cover, battery compartment, power supply module and thermal imaging device. Background Technology
[0002] Thermal imaging equipment is typically equipped with a separate power supply module. This module includes a battery compartment, a battery, and a battery cover. The bottom wall of the battery compartment has a first conductive terminal, and the opening of the battery compartment has a second conductive terminal. After the battery and battery cover are assembled, one end of the battery is electrically connected to the first conductive terminal, and the other end of the battery rests against the battery cover. The battery cover rests against the second conductive terminal. Since the battery cover is a conductor, the end of the battery can be electrically connected to the second conductive terminal through the cover. Once the first and second conductive terminals are electrically connected to the two ends of the battery, power can be supplied to the imaging components of the thermal imaging equipment.
[0003] When the thermal imaging device is shaken or impacted, the battery cover may become misaligned and separate from the battery end, resulting in a power outage between the first and second conductive terminals, preventing the thermal imaging device from imaging properly. In other words, existing thermal imaging devices lack operational stability when shaken or impacted. Utility Model Content
[0004] Therefore, it is necessary to provide a battery cover, battery compartment, power supply module, and thermal imaging device to address the problem of insufficient operational stability of thermal imaging devices when shaken or impacted.
[0005] A battery cover includes a conductive cover body having a first conductive portion for abutting against a battery end. The battery cover also includes a first conductive elastic member, one end of which abuts against the conductive cover body, and the other end of which abuts against a battery end.
[0006] In one embodiment, the battery cover includes a conductive element movably mounted on the conductive cover body along the axial direction of the first conductive elastic element, the conductive element having an adapter portion on which the first conductive elastic element abuts.
[0007] In one embodiment, the conductive member further has a limiting portion, at least a portion of which is projected axially onto the first conductive elastic member.
[0008] In one embodiment, the conductive cover includes a first conductor and a second conductor designed separately from the first conductor, the second conductor being mounted on and in contact with the first conductor, the first conductive portion being a part of the second conductor, the limiting portion being located between the first conductive portion and the first conductor, and the end of the first conductive elastic member abutting against the first conductor.
[0009] A battery compartment, comprising the aforementioned battery cover and compartment body;
[0010] A first conductive terminal is provided at the bottom wall of the compartment, and the first conductive terminal is used to abut the end of the battery.
[0011] A second conductive terminal is provided at the opening of the compartment, and the conductive cover has a second conductive part. The conductive cover is installed at the opening of the compartment so that the second conductive terminal abuts against the second conductive part.
[0012] In one embodiment, a circuit board is provided at the opening of the compartment, and the second conductive terminal is elastically and retractably disposed on the circuit board.
[0013] In one embodiment, a second conductive elastic element is provided between the first conductive terminal and the bottom wall of the chamber.
[0014] In one embodiment, a sealing ring is provided on the periphery of the conductive cover.
[0015] A power supply module includes a battery compartment and a battery, the battery being installed in the compartment, a first conductive terminal abutting one end of the battery, and a first conductive part and a first conductive elastic element abutting the other end of the battery.
[0016] A thermal imaging device includes a body and a power supply module, wherein the housing is mounted on the body so that the first conductive terminal and the second conductive terminal are electrically connected to the body.
[0017] The beneficial effects of this utility model are as follows:
[0018] Compared with the prior art, the battery cover of this utility model has an additional first conductive elastic element that abuts against the conductive cover body.
[0019] When the battery cover is in place and the thermal imaging device has not been impacted, both the first conductive part and the end of the first conductive elastic member can abut against one end of the battery. At this time, the battery end can be electrically connected to the second conductive terminal via the first conductive elastic member and the second conductive part, or vice versa, thereby enabling electrical connection between the battery end and the second conductive terminal. Furthermore, the addition of a conductive path between the first conductive elastic member and the second conductive part reduces the resistance between the battery end and the second conductive terminal.
[0020] When the thermal imaging device is impacted or shaken, causing a gap between the battery cover and the battery end, the first conductive elastic element recovers so that its end can stably abut against the battery end, maintaining the smooth conductive path of the battery end, the first conductive elastic element, and the second conductive part, reducing the risk of power failure between the second conductive terminal and the battery end, and thereby improving the working stability of the thermal imaging device when it is impacted or shaken.

[0039] Example:
[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a thermal imaging device, including a body 4 and a power supply module. The power supply module is installed on the body 4 to supply power to the body 4. When the body 4 receives power, it can perform thermal imaging normally.
[0041] Specifically, the power supply module includes a battery compartment and a battery 2. The battery compartment includes a battery cover 1 and a compartment body 3. The battery 2 is installed inside the compartment body 3, and the battery cover 1 is detachably installed at the opening of the compartment body 3.
[0042] like Figure 1 and Figure 3 As shown, a first conductive terminal 31 is provided on the bottom wall of the compartment 3, such as... Figure 2 and Figure 4As shown, a second conductive terminal 32 is provided at the opening of the compartment 3. The compartment 3 is mounted on the body 4 so that the first conductive terminal 31 and the second conductive terminal 32 are electrically connected to the body 4.
[0043] For example, a circuit board 33 is provided at the opening of the compartment 3, and a second conductive terminal 32 is mounted on the circuit board 33. The second conductive terminal 32 is located at the opening of the compartment 3 through the circuit board 33 and is electrically connected to the main body 4 through the circuit board 33. The way in which the first conductive terminal 31 and the circuit board 33 are electrically connected to the main body 4 is prior art and will not be described in detail in this embodiment.
[0044] See Figure 5 The battery cover 1 includes a conductive cover body 11 and a first conductive elastic element 12. The conductive cover body 11 has a first conductive portion 111 and a second conductive portion 114. Since the main structure of the conductive cover body 11 is a conductor, the first conductive portion 111 and the second conductive portion 114 are electrically connected to each other. The first conductive elastic element 12 is mounted on the conductive cover body 11, and one end of the first conductive elastic element 12 abuts against the conductive cover body 11, so that the first conductive elastic element 12 is conductive to the second conductive portion 114.
[0045] like Figure 8 As shown, when the battery cover 1 is installed in place and the thermal imaging device is not impacted, the ends of the first conductive part 111 and the first conductive elastic member 12 can both abut against one end of the battery 2, while the other end of the battery 2 abuts against the first conductive terminal 31. Figure 8 As shown by the dashed line, the end of battery 2 can be electrically connected to the second conductive terminal 32 via the first conductive elastic element 12 and the second conductive part 114, or via the first conductive part 111 and the second conductive part 114. This allows the end of battery 2 to be electrically connected to the second conductive terminal 32. In other words, the first conductive terminal 31 and the second conductive terminal 32 are respectively connected to the positive and negative terminals of battery 2, thereby supplying power to the main body 4 and ensuring its normal operation. Furthermore, compared to the prior art where the end of battery 2 and the second conductive terminal 32 are only connected via the first conductive part 111 and the second conductive part 114, this embodiment adds a conductive path between the first conductive elastic element 12 and the second conductive part 114, thereby reducing the resistance between the end of battery 2 and the second conductive terminal 32.
[0046] like Figure 9As shown, when the thermal imaging device is impacted or shaken, the battery cover 1 may deform or become misaligned, resulting in a gap between the battery cover 1 and the end of the battery 2. The end of the battery 2 may then separate from the first conductive part 111, preventing it from being electrically connected to the second conductive terminal 32 via the passage between the first conductive part 111 and the second conductive part 114. However, the gap between the battery cover 1 and the end of the battery 2 allows the first conductive elastic element 12 to recover to a certain extent, maintaining stable contact with the end of the battery 2 and ensuring the smooth flow of the conductive path between the end of the battery 2, the first conductive elastic element 12, and the second conductive part 114. In other words, by adding the first conductive elastic element 12 to the conductive cover 11, the stability of the electrical connection between the end of the battery 2 and the second conductive part 114 can be maintained when the thermal imaging device is impacted or shaken, reducing the risk of power failure between the second conductive terminal 32 and the end of the battery 2, thereby improving the operational stability of the thermal imaging device when impacted or shaken.
[0047] Based on similar principles, such as Figure 3 As shown, in this embodiment, a second conductive elastic element 34 is provided between the first conductive terminal 31 and the bottom wall of the housing 3. The first conductive terminal 31 can be electrically connected to the body 4 through the second conductive elastic element 34. When the thermal imaging device is impacted or shaken, causing the first conductive terminal 31 to separate from the end of the battery 2, the second conductive elastic element 34 restores its original shape, ensuring the contact stability between its end and the end of the battery 2.
[0048] Furthermore, the second conductive terminal 32 is elastically retractable on the circuit board 33, so that when the battery cover 1 deforms or moves on the compartment 3, the second conductive terminal 32 can automatically extend and maintain contact with the second conductive part 114.
[0049] For example, this embodiment provides a specific structure for the second conductive terminal 32. For example... Figure 7 As shown, the second conductive terminal 32 includes a conductive rod 321, a conductive tube 322, and an elastic element. One end of the conductive tube 322 can be soldered onto the circuit board 33. The conductive rod 321 passes through the other end of the conductive tube 322. The conductive rod 321 can move axially along the conductive tube 322 and contacts the inner wall of the conductive tube 322 to keep the conductive rod 321 and the conductive tube 322 in a conductive state. The elastic element is located inside the conductive tube 322, and its two ends abut against the end of the conductive rod 321 and the circuit board 33, respectively. The end of the conductive rod 321 outside the conductive tube 322 can abut against the second conductive part 114.
[0050] like Figure 5As shown, the battery cover 1 in this embodiment also includes a conductive member 13, which is movably mounted on the conductive cover body 11 along the axial direction of the first conductive elastic member 12. The conductive member 13 has an adapter portion 131, and the first conductive elastic member 12 abuts against the adapter portion 131. Figure 8 and Figure 9 As shown, the end of the first conductive elastic element 12 always abuts against the end of the battery 2 through the adapter 131, and is also always electrically connected to the end of the battery 2 through the adapter 131. The shape of the adapter 131 matches the shape of the end face of the battery 2 and the shape of the end of the first conductive elastic element 12, thereby enabling both the end face of the battery 2 and the end of the first conductive elastic element 12 to maintain a large contact area with the adapter 131, improving the stability of the electrical connection between the first conductive elastic element 12 and the battery 2. For example, in this embodiment, the first conductive elastic element 12 is a metal spring, the end face of the battery 2 is a plane, and the adapter 131 is flat, with the end of the first conductive elastic element 12 and the end face of the battery 2 pressed against the two sides of the adapter 131 respectively.
[0051] See further Figure 5 The conductive element 13 also has a limiting portion 132. In this embodiment, the limiting portion 132 is located at the edge of the adapter portion 131 to avoid interference between the adapter portion 131 and the end face of the battery 2. At least a portion of the projection of the limiting portion 132 in the axial direction of the first conductive elastic element 12 is located on the first conductive portion 111, thereby limiting the conductive element 13 through the first conductive portion 111, and thus preventing the first conductive elastic element 12 and the conductive element 13 from detaching from the conductive cover 11.
[0052] like Figure 5 and Figure 6 As shown, the conductive cover 11 in this embodiment includes a first conductor 112 and a second conductor 113 that is separately designed from the first conductor 112. The second conductor 113 is mounted on the first conductor 112 and contacts the first conductor 112, thereby making the first conductor 112 and the second conductor 113 conductive. The first conductor 112 and the second conductor 113 can be made of different conductive materials to meet cost control requirements.
[0053] In this embodiment, both the first conductive part 111 and the second conductive part 114 are part of the second conductor 113. The limiting part 132 is located between the first conductive part 111 and the first conductor 112, and the end of the first conductive elastic member 12 abuts against the first conductor 112. When the second conductor 113 is removed from the first conductor 112, the limiting part 132 loses the limiting function of the first conductive part 111. In other words, based on the removal and installation of the second conductor 113 on the first conductor 112, the removal and installation of the first conductive elastic member 12 and the conductive member 13 on the conductive cover 11 can also be realized.
[0054] like Figures 8-10As shown, the thermal imaging device in this embodiment also includes a rear shell 5, on which an avoidance opening 51 is provided. The opening of the chamber 3 is fixed in the middle of the avoidance opening 51. A sealing ring 115 is provided on the periphery of the conductive cover 11. The sealing ring 115 is pressed between the edge of the conductive cover 11 and the avoidance opening 51. The sealing ring 115 can improve the sealing performance inside the chamber 3 on the one hand, and increase the positional stability of the conductive cover 11 at the opening of the chamber 3 on the other hand.
[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
