[0003] If the electronic components and battery are both located on the temple, the temple is usually divided into two sections for ease of manufacturing. One section integrates the speaker and processing devices, while the other section integrates the battery and the necessary power supply components. The two sections are assembled separately and then spliced ​​together. However, installing the battery and the necessary power supply components involves the issue of whether the battery is installed correctly or incorrectly, and splicing the two temple sections also involves the issue of whether they are installed correctly or incorrectly, which makes the manufacturing of the temple inconvenient.

Detailed Implementation

[0025] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This utility model provides a battery assembly.

[0028] Reference Figure 1-3 The battery assembly includes a battery 1, a battery housing 2, a circuit board 3, a positive terminal 4, and a negative terminal 5. Specifically, the battery housing 2 is connected to the front section of the temple 9. The battery housing 2 is provided with a receiving groove 21. The battery 1 is inserted into the receiving groove 21 through the opening of the groove. After the battery 1 enters the receiving groove 21 and abuts against the bottom of the groove 21, the battery 1 will be completely contained in the receiving groove 21 and will not move around in the receiving groove 21. Therefore, the shape and size of the receiving groove 21 must be designed according to the shape and size of the battery 1. At the same time, after the battery 1 is inserted into the receiving groove 21, the opening of the receiving groove 21 will be sealed to meet the waterproof and dustproof requirements of the battery assembly.

[0029] Circuit board 3 is connected to battery 1. Circuit board 3 has a rectifier circuit, such as a bridge rectifier circuit. So, whether battery 1 and circuit board 3 are connected in the correct direction or in the reverse direction, the positions of the positive and negative terminals of the circuit board 3 that transmit current will not change, so as to achieve reverse connection protection at the circuit level.

[0030] The positive terminal 4 is electrically connected to the rectifier circuit of the circuit board 3 and is connected to the positive output of the circuit board 3. The negative terminal 5 is electrically connected to the rectifier circuit of the circuit board 3 and is connected to the negative output of the circuit board 3. The two negative terminals 5 are symmetrically arranged with respect to one positive terminal 4. So no matter how the battery assembly rotates, the positive terminal 4 is always in the middle, while the two negative terminals 5 are still on both sides. This can achieve reverse connection protection at the mechanical level.

[0031] The battery assembly installation steps are as follows: First, complete the connection between battery 1, circuit board 3, positive terminal 4 and negative terminal 5. Then, put battery 1 into the receiving slot 21. Then, connect the battery assembly to the front section of the temple 9. The positive terminal 4 is connected to the positive receiving terminal in the front section of the temple 9, and the negative terminal 5 is connected to the negative receiving terminal in the front section of the temple 9.

[0032] In summary, by using a rectifier circuit to achieve reverse connection protection at the circuit level, the assembly between battery 1 and circuit board 3 becomes more convenient. By using the positive terminal 4 and negative terminal 5 to achieve reverse connection protection at the mechanical level, the assembly between the battery assembly and the front section of temple 9 becomes more convenient, thus making the production and manufacturing of temple 9 more convenient.

[0033] There are many types of batteries, such as cylindrical batteries and button batteries. Cylindrical batteries have a larger capacity than button batteries and are commonly used in remote controls and large toys, while button batteries are generally used in devices with lower power consumption, such as watches.

[0034] In this embodiment, reference is made to... Figure 1 The selection of battery 1 needs to consider two factors. First, as smart glasses become more functional, the demand for battery 1's capacity gradually increases. Therefore, from a power perspective, cylindrical battery 1 is more suitable. Second, since the battery assembly is located at the end of the temple 9, and for aesthetic and practical purposes, the battery assembly needs to adapt to the shape of the temple 9, making cylindrical battery 1 a more appropriate choice.

[0035] Given that the battery 1 is selected as a cylindrical battery 1, the length direction of the battery 1 will be parallel to the center line direction of the groove opening of the receiving groove 21.

[0036] As mentioned above, after battery 1 is inserted into the receiving slot 21, the opening of the receiving slot 21 will be sealed. There are two scenarios for this sealing. The first is that the opening of the receiving slot 21 is sealed only after the battery assembly is spliced ​​with the front section of the temple 9. In this case, the opening of the receiving slot 21 is sealed by the front section of the temple 9, so before splicing the battery assembly, battery 1 needs to be fixed in the receiving slot 21 with glue. The second scenario is that the opening of the receiving slot 21 is sealed before the battery assembly is assembled with the front section of the temple 9. In this case, after battery 1 is inserted into the receiving slot 21, a cover is installed at the opening of the receiving slot 21. This cover, together with the battery housing 2, encloses battery 1. After the cover is installed, the battery assembly is then spliced ​​with the front section of the temple 9.

[0037] Since the battery assembly and the front section of the temple 9 are assembled together, there are requirements for the sealing of the splice between the battery assembly and the front section of the temple 9. Since the front section of the temple 9 and the battery housing 2 are both in the form of tubular shells at their closest ends, there are two ways to achieve this. The first is to use a nested tubular shell with a sealing ring. The second is to add a plug to the inner wall of one of the tubular shells, and this plug is interference-fitted with the inner wall of the other tubular shell.

[0038] In summary, referring to 2-4, based on the two sealing methods of the receiving slot 21 and the two splicing sealing methods, from the perspective of structural simplicity, it is chosen that the opening of the receiving slot 21 be sealed before the battery assembly and the front section of the temple 9 are assembled. Specifically, an end cap 6 is sealed at the opening of the receiving slot 21, and the positive terminal 4 and the negative terminal 5 are positioned at the corresponding positions of the opening of the receiving slot 21. That is, the battery housing 2 does not need to open a window from the side wall of the receiving slot 21 for the positive terminal 4 and the negative terminal 5. Instead, the part of the end cap 6 outside the receiving slot 21 is inserted into the splicing interface of the front section of the temple 9, thus achieving the sealing of the receiving slot 21 and the splicing between the two sections of the temple 9 through the simplest structure.

[0039] Reference Figure 1-3 In this embodiment, the end cap 6 and the battery housing 2 can be glued or ultrasonically welded. Considering the stability of the end cap 6 and the battery housing 2 during the fixing process, a positioning groove 7 is provided on the outer wall of the end cap 6 that contacts the receiving groove 21. There are two positioning grooves 7 symmetrically arranged with respect to the center line of the end cap 6. Each positioning groove 7 is hemispherical. At the same time, a positioning block 8 is formed on the inner wall of the receiving groove 21. One positioning block 8 is adapted to one positioning groove 7. The initial stable connection between the end cap 6 and the battery housing 2 is achieved through the cooperation between the positioning block 8 and the positioning groove 7, which facilitates the subsequent glued or ultrasonically welded connection.

[0040] As mentioned above, both the positive terminal 4 and the negative terminal 5 are located at corresponding positions in the slot 21. Based on this layout, to more easily achieve the connection between the circuit board 3, the positive terminal 4, and the negative terminal 5, the following arrangement is preferred: the circuit board 3 is disposed in the slot 21 and located at the slot 21 opening; both the positive terminal 4 and the negative terminal 5 are passed through and fixed to the end cap 6, specifically through an interference fit; and both the positive terminal 4 and the negative terminal 5 are also passed through and fixed to the circuit board 3, specifically by passing through the circuit board 3 and then soldering them to the circuit board 3.

[0041] In summary, during assembly, the positive terminal 4, negative terminal 5, end cap 6, and circuit board 3 can be assembled together first. Then, the circuit board 3 can be connected to the battery 1. Finally, after the battery 1 is inserted into the receiving slot 21, the end cap 6 can be inserted into the opening of the receiving slot 21, which further makes the assembly of the battery assembly more convenient.

[0042] Reference Figure 2-4 Based on the aforementioned adhesive or ultrasonic welding of the end cap 6 and the battery housing 2, the sealing performance between the end cap 6 and the battery housing 2 is improved. In order to improve the sealing performance between the end cap 6 and the front section of the temple 9, the following configuration is provided: the end cap 6 is divided into a splicing part 61 and a connecting groove part 62. The splicing part 61 is used to connect the temple 9, that is, it is inserted into the splicing interface of the front section of the temple 9. The connecting groove part 62 connects to the inner wall of the receiving groove 21 near the groove opening. The connecting groove part 62 is thicker than the splicing part 61 so that the connecting groove part 62 abuts against the end face of the front section of the temple 9 housing at the splicing interface. In this way, the connecting groove part 62 will block the gap between the splicing part 61 and the front section of the temple 9 housing, thereby improving the splicing sealing performance between the end cap 6 and the front section of the temple 9.

[0043] Reference Figure 2-4 In order to avoid rotational misalignment between the battery assembly and the front section of the temple 9 during the splicing process, rotational misalignment here refers to the situation that if the splicing part 61 is cylindrical or regular polygonal prism, the positive end 4 may be aligned, but the negative end 5 may not be aligned. Therefore, the splicing part 61 is designed as a non-centrally symmetrical cylindrical shape, such as an elliptical cylinder.

[0044] Reference Figure 5In addition, to make the splicing part 61 of the end cap 6 more firmly connected to the previous temple 9, a splicing protrusion 611 is provided on the splicing part 61, and a splicing groove 612 is provided on the previous temple 9. Here, the splicing protrusion 611 refers to the plastic buckle protrusion, and the splicing groove 612 refers to the plastic buckle recess. During assembly, when the splicing part 61 is inserted into the previous temple 9, the splicing protrusion 611 is engaged with the splicing groove 612 under pressure. In this way, the end cap 6 and the previous temple 9 will be more firmly connected.

[0045] Reference Figure 3 In order to extend the service life of battery 1 and ensure safe use, a protection chip 31 is also provided on the circuit board 3. The protection chip 31 is electrically connected to the circuit board 3, that is, the protection chip 31 is soldered to the circuit board 3. At the same time, the battery 1 and the protection chip 31 are also connected together by soldering wires. When the battery 1 is over-discharged or overcharged, the protection chip 31 can react in time and cut off the corresponding circuit, effectively preventing the battery 1 from being damaged due to over-discharge or overcharge, and providing a guarantee for the safe operation of the battery assembly.

[0046] This application also discloses a temple, which includes the battery assembly mentioned in the foregoing embodiments.

[0047] This application also discloses a smart glasses, which includes the battery assembly mentioned in the foregoing embodiments.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
