Description

Technical Field

[0001] The utility model relates to the technical field of batteries, and in particular to a sensor battery pack structure that can be quickly installed. Background Art

[0002] With the development of Internet of Things technology, sensors are increasingly used in nodes of the Internet of Things. As one of the sensors, passenger flow counting sensors are people counting sensors designed for aisle flow analysis. They use infrared sensors or thermopile technologies to detect human infrared heat energy to achieve crowd counting in scenes such as conference rooms, convenience stores, shopping malls and toilets.

[0003] Some passenger counting sensors are equipped with battery packs, and the passenger counting sensors are generally fixed at high places by means of door lintel installation and ceiling installation. Since the battery life of the battery pack is limited (such as the battery of the battery pack is exhausted or damaged), the battery pack needs to be replaced regularly. However, the battery pack is installed in the passenger counting sensor, which makes it difficult to remove and install the battery pack. In addition, the power supply end of the battery pack and the power receiving end of the passenger counting sensor are electrically connected by means of screw connection or welding, so it is difficult to replace.

[0004] In addition, because the passenger flow counting sensor is fixed at a high place, the passenger flow counting sensor needs to be taken down from the high place before the battery pack can be replaced. At this time, the installation height of the passenger flow counting sensor is relatively high, and it is necessary to climb up and disassemble the corresponding fixing screws, which makes it difficult to manually replace the battery pack.

These drawings are part of the disclosure of the present invention, which 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 contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0029] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figures 1 to 5 As shown, this embodiment provides a sensor battery pack structure that can be quickly installed (hereinafter referred to as a battery pack structure), and the battery pack structure includes the following Figure 8 The sensor body 1 and the power supply for the sensor body 1 are as follows Figure 6 The battery pack body 2, the sensor body 1 and the battery pack body 2 are independently arranged. The sensor body 1 has a power receiving end, and the power receiving end includes two first electrode sheets 11. The battery pack body 2 has a power supply end that is plugged with the power receiving end. The power supply end includes two second electrode sheets 21. The first electrode sheet 11 has an elastic Figure 3 The bent portion 111 shown in FIG. 1 is a second electrode sheet 21 having a rigid Figure 4 As shown in the plug-in portion 211 , the first electrode sheet 11 corresponds to the second electrode sheet 21 one by one to form a group setting, and the plug-in portions 211 of the same group abut against the bending portions 111 of the same group to form a quick-install electrical connection setting between the sensor body 1 and the battery pack body 2 .

[0031] In this embodiment, the battery pack of the sensor adopts the above-mentioned battery pack structure, such as Figure 7 The battery pack body 2 shown includes a battery pack shell 23 and four batteries 24, the batteries 24 are detachably mounted in the battery pack shell 23, and the batteries 24 and the power supply end are electrically connected via a third electrode sheet 25, and the third electrode sheet 25 is fixedly mounted on the battery pack shell 23. Specifically, the battery pack shell 23 includes a battery cover and a battery shell for accommodating the batteries 24, and the battery cover is detachably mounted on the battery shell.

[0032] The battery pack shell 23 has a clearance opening for making way for the power supply end, and the second electrode sheet 21 passes through the clearance opening. At this time, the straight-line portion of the second electrode sheet 21 located outside the clearance opening is the plug-in portion 211 of the second electrode sheet 21, and the plug-in portion 211 has an inclined guide surface at one end facing the power receiving end to facilitate smooth plug-in operation.

[0033] The first electrode sheet 11 also has a fixing portion 112 connected to the bent portion 111. The sensor body 1 has a sensor housing, and the sensor housing has a plug-in slot 12 for accommodating the power receiving end and a plug-in port extending through the plug-in slot 12. The fixing portion 112 is fixed in the plug-in slot 12 of the sensor body 1. The bent portion 111 is suspended, and the fixing portion 112 and the bent portion 111 are connected to form a hook-shaped structure, so that the bent portion 111 is suspended on one side.

The bending portion 111 relies on its own elastic force to form an elastic abutment with the plug-in portion 211 to form a reliable and stable electrical connection.

[0035] When the power receiving end and the power supply end are separated, the plug-in part 211 of the battery pack main body 2 is also separated from the extraction slot 12 of the sensor main body 1. During the replacement of the battery pack main body 2, the maintenance personnel are required to use force to overcome the limitation of the elastic force and pull the plug-in part 211 out of the battery pack main body 2 to achieve lossless and quick disassembly, and then replace the old battery 24 in the battery pack main body 2 with a new battery 24, and then connect the battery pack main body 2 replaced with the new battery 24 and the sensor main body 1 to ensure normal subsequent power supply.

When the shielding member 22 and the plug-in portion 211 are simultaneously inserted into the corresponding plug-in slot 12, the plug-in portion 211 and the bending portion 111 of the same group are also located in the concave groove of the shielding member 22 to achieve an embracing setting, thereby achieving that the plug-in portion 211 and the bending portion 111 of the same group will not contact other conductors to prevent a short circuit from occurring.

[0041] Further preferably, an inclined guide surface is provided at one end of the bending portion 111 facing the plug-in portion 211 , and at the same time, an inclined guide surface is provided at the plug-in port of the sensor body 1 , so as to facilitate smooth introduction of the plug-in portion 211 into the corresponding plug-in slot 12 and abutment against the corresponding bending portion 111 .

[0042] In another preferred embodiment, the third electrode sheet 25 is a spring sheet and has a plug-in slot.
