Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to a battery device and an electronic device. Background Technology

[0002] Electronic devices (such as law enforcement recorders and walkie-talkies) may include a battery device and a main body. The battery device is detachably connected to the main body. The battery device is equipped with a locking mechanism, which can be used to lock or unlock the battery device by sliding the locking mechanism. In related technologies, when foreign objects intrude into the gaps at the locking mechanism, it can easily cause the locking mechanism to become stuck, affecting the use of the battery device. Utility Model Content

[0003] This application provides a battery device and an electronic device that can solve the technical problem of locking parts becoming stuck due to the intrusion of foreign objects.

[0004] To address the aforementioned technical problems, this application provides a battery device, comprising a housing assembly and a locking assembly. The housing assembly has a sliding cavity and a button hole, the button hole communicating with the sliding cavity. The locking assembly includes a movable member and a locking member. The movable member is slidably mounted in the sliding cavity along a first direction and has a receiving groove. The locking member includes a guide portion and a locking portion. The guide portion is slidably disposed in the receiving groove along a second direction, which intersects with the first direction. At least a portion of the guide portion is exposed outside the button hole. The locking portion is connected to the guide portion. The locking member has a first position and a second position relative to the movable member. In the first position, the locking portion locks the movable member to the housing assembly. In the second position, the locking portion unlocks the movable member, allowing the movable member to slide along the first direction. During the process of the locking member moving from the first position to the second position, the gap between at least a portion of the outer wall of the guide portion and the groove wall of the receiving groove increases.

[0005] In another aspect, this application provides an electronic device, which includes a battery device and a device body as described above, wherein the battery device and the device body are detachably connected.

[0006] The battery device provided in this application increases the gap between at least part of the outer wall of the guide portion and the wall of the receiving groove during the process of the locking member moving from the first position to the second position. This can reduce the constraint of the receiving groove on foreign objects between the locking member and the moving member, allowing the foreign objects to move with the locking member, thereby reducing the possibility of the locking member sliding and getting stuck.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. 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.

[0022] This application provides an electronic device. Exemplarily, the electronic device may be a handheld terminal, such as a law enforcement recorder, walkie-talkie, or other electronic equipment. Please refer to [link to relevant documentation]. Figure 1 The electronic device 500 may include a battery device 100 and a device body 200. The battery device 100 is used to provide electrical energy to the device body 200 during operation. The battery device 100 is detachably connected to the device body 200, which facilitates the maintenance and replacement of the battery device 100.

[0023] Please see Figures 2-6The battery device 100 may include a battery assembly 10, a housing assembly 20, and a locking assembly 30. The battery assembly 10 is mounted on the housing assembly 20, which provides protection for the battery assembly 10. The housing assembly 20 has a sliding cavity 27 and a button hole 221 communicating with the sliding cavity 27. The locking assembly 30 is used to detachably mount the battery device 100 to the electronic device 500. The locking assembly 30 includes a movable member 32 and a locking member 31. The movable member 32 is used to connect to the device body 200. The movable member 32 is slidably mounted in the sliding cavity 27 along a first direction. Exemplarily, the first direction may be... Figure 4 The moving part 32 has a receiving groove 325. The locking part 31 includes a guide part 311 and a locking part 312. The guide part 311 is slidably disposed in the receiving groove 325 along the second direction. The second direction is intersecting the first direction. That is, the second direction is different from the first direction, and there is an angle between the second direction and the first direction. For example, the second direction can be the X-axis direction. Figure 4 The Z-axis direction is shown. At least part of the guide portion 311 is exposed through the button hole 221, allowing the user to operate the guide portion 311 via the button hole 221. The locking portion 312 is connected to the guide portion 311. The locking portion 312 can be integrally formed with the guide portion 311, or it can be machined separately and then assembled. The guide portion 311 drives the locking portion 312 to slide, thereby unlocking or locking the moving part 32, thus facilitating the removal of the battery device 100 from the device body 200, or the installation of the battery device 100 onto the device body 200.

[0024] The locking member 31 has a first position and a second position relative to the movable member 32. As the locking member 31 slides in the receiving groove 325, it can move between the first and second positions. In the first position, the locking part 312 locks the movable member 32 to the housing assembly 20, restricting the sliding of the movable member 32 and thus securing the battery device 100 to the device body 200 to prevent it from falling off. In the second position, the locking part 312 unlocks the movable member 32, allowing it to slide in a first direction, thus enabling the battery device 100 to be detached from the device body 200.

[0025] There is a certain gap between the outer wall of the guide portion 311 and the groove wall of the receiving groove 325 to ensure that the guide portion 311 can slide smoothly within the receiving groove 325. In related technologies, when foreign objects intrude into the gap, it can easily cause the locking member 31 to slide and get stuck, making it difficult for the locking member 31 to move to the second position. As a result, the battery device 100 cannot be removed from the main body 200, affecting the use of the battery device 100.

[0026] To solve the above-mentioned technical problems, the battery device 100 provided in this application, such as Figures 7-9As shown, during the process of the locking member 31 moving from the first position to the second position, the gap between at least a portion of the outer wall of the guide portion 311 and the groove wall of the receiving groove 325 increases. This arrangement reduces the constraint of the receiving groove 325 on foreign objects between the locking member 31 and the moving member 32, allowing foreign objects to move with the locking member 31, thereby reducing the possibility of the locking member 31 sliding and getting stuck.

[0027] In one embodiment, such as Figure 7 As shown, the locking member 31 moves from a first position to a second position under a pushing or pulling action. For example, the guide portion 311 is provided with a pull ring or pull cord, which can be used to apply a pulling force to the guide portion 311, causing the locking member 31 to move towards the external space of the battery device 100 to unlock the movable member 32. The receiving groove 325 has a first groove segment 3251 and a second groove segment 3252 arranged adjacent to each other in a second direction. The second groove segment 3252 communicates with the external space of the battery device 100 through the first groove segment 3251. The guide portion 311 is exposed at the end of the first groove segment 3251 away from the second groove segment 3252 through the button hole 221. That is, the first groove segment 3251 is closer to the external space of the battery device 100 than the second groove segment 3252. In a reference cross section perpendicular to the second direction, at least a portion of the second groove segment 3252 is smaller than the first groove segment 3251. That is, the cross-sectional area of ​​the receiving groove 325 at the point where it communicates with the external space of the battery device 100 is larger than the cross-sectional area of ​​other adjacent areas. With this configuration, when it is necessary to unlock the movable part 32, the button hole 221 can be placed downwards, and the user can apply a pulling force to the guide part 311, causing the locking part 31 to move to the second position towards the external space of the battery device 100, thereby unlocking the movable part 32. During the process of the locking part 31 moving from the first position to the second position, the constraint of the receiving groove 325 on foreign objects between the locking part 31 and the movable part 32 is reduced, allowing foreign objects to move with the locking part 31. Under the action of gravity, the foreign objects can fall to the outside of the battery device 100, thereby reducing the possibility of the locking part 31 sliding and getting stuck.

[0028] In one embodiment, such as Figure 8 , Figure 9As shown, the locking member 31 moves from a first position to a second position under pressure. For example, a user can apply pressure to the end of the guide portion 311, causing the locking member 31 to move towards the internal space of the battery device 100 to unlock the movable member 32. The receiving groove 325 has a first groove segment 3251 and a second groove segment 3252 arranged adjacent to each other in a second direction. The second groove segment 3252 communicates with the external space of the battery device 100 through the first groove segment 3251. The guide portion 311 protrudes from the end of the first groove segment 3251 away from the second groove segment 3252 into the button hole 221. That is, the first groove segment 3251 is closer to the external space of the battery device 100 than the second groove segment 3252. In a reference cross section perpendicular to the second direction, at least a portion of the second groove segment 3252 is larger than the first groove segment 3251. That is, the cross-sectional area of ​​the receiving groove 325 at the point where it communicates with the external space of the battery device 100 is smaller than the cross-sectional area of ​​other adjacent areas. With this configuration, when the movable part 32 needs to be unlocked, the button hole 221 can be placed upwards, and the user applies pressure to the guide portion 311, causing the locking part 31 to move towards the internal space of the battery device 100 to the second position, thereby unlocking the movable part 32. During the process of the locking part 31 moving from the first position to the second position, the constraint of the receiving groove 325 on foreign objects between the locking part 31 and the movable part 32 is reduced, allowing foreign objects to move with the locking part 31. Under the action of gravity, the foreign objects can fall to the bottom of the receiving groove 325, thereby reducing the possibility of the locking part 31 sliding and getting stuck. Relatively speaking, on the one hand, applying pressure to the guide portion 311 with the button hole 221 facing upwards is more convenient and helps improve the usability of the battery device 100; on the other hand, the cross-sectional area of ​​the connection between the receiving groove 325 and the external space of the battery device 100 is smaller, which can reduce the possibility of external foreign objects intruding into the gap between the outer wall of the guide portion 311 and the groove wall of the receiving groove 325.

[0029] The extension direction of the first groove segment 3251 can be parallel to the second direction to constrain the sliding direction of the guide portion 311 and prevent the guide portion 311 from deviating during sliding. Due to limitations in the manufacturing process, the parallelism or perpendicularity in this application can have a deviation of ±5 degrees. In the first position, the end of the guide portion 311 away from the internal space of the battery device 100 can be flush with the movable member 32, which can reduce the risk of the battery device 100 being unlocked due to accidental contact with the guide portion 311, and also prevent the guide portion 311 from being exposed and affecting the appearance of the battery device 100.

[0030] In one embodiment, such as Figure 9As shown, the dimension of the first groove segment 3251 in the second direction is greater than the travel distance of the locking member 31 from the first position to the second position. During the movement of the locking member 31 from the first position to the second position, a portion of the guide portion 311 is always located within the range of the first groove segment 3251. The first groove segment 3251 can constrain the sliding direction of the guide portion 311, thereby preventing the guide portion 311 from deviating during sliding. In the second position, the ratio α of the dimension of the guide portion 311 projected along the first direction within the first groove segment 3251 to the dimension of the first groove segment 3251 in the second direction is less than or equal to 0.25. If the ratio α is greater than 0.25, the dimension of the guide portion 311 within the range of the first groove segment 3251 is larger, while the gap between the groove wall of the first groove segment 3251 and the outer wall of the guide portion 311 is smaller, increasing the risk of foreign objects getting stuck in the first groove segment 3251. For example, the ratio α can be 0.25, 0.2, 0.18, 0.15, 0.12 or 0.1, etc., without being specifically limited here.

[0031] Please see Figure 5 In one embodiment, locking portions 312 are spaced apart on both sides of guide portion 311 along a third direction, wherein the third direction, the first direction, and the second direction are perpendicular to each other. The third direction may be... Figure 5 The Y-axis direction in the middle. The housing assembly 20 includes a limiting member 24, which is disposed on the side wall of the sliding cavity 27, such as Figure 10 As shown. There can be two limiting members 24, each disposed on one side of the sliding cavity 27. In the first position, the locking part 312 abuts against the limiting member 24 on one side in the first direction, locking the movable member 32 to the housing assembly 20, thereby restricting the movable member 32 from sliding in the first direction; in the second position, the locking part 312 separates from the limiting member 24 on one side in the first direction, and abuts against the limiting member 24 on one side in the second direction, unlocking the movable member 32, allowing it to slide in the first direction. The receiving groove 325 can be cylindrical, with an opening in the third direction on its side wall. The locking part 312 is exposed through the opening in the receiving groove 325, allowing it to abut against the limiting member 24. At this time, the guide part 311 and the locking part 312 are separate structures, and the locking part 312 can be installed to the guide part 311 through the opening. Alternatively, as... Figure 6 As shown, the receiving groove 325 penetrates the movable member 32 along the third direction. That is, the receiving groove 325 has no side walls on both sides in the third direction, and the side walls of the receiving groove 325 will not affect the cooperation between the locking part 312 and the limiting member 24. At this time, the guide part 311 and the locking part 312 can be an integral structure. Compared with the separate structure, it can reduce the assembly steps and improve the assembly efficiency of the battery device 100.

[0032] The guide portion 311 may be cylindrical, and correspondingly, the groove wall of the second groove segment 3252 may be a portion of the outer surface of a frustum. Alternatively, in one embodiment, the guide portion 311 is cylindrical, and the outer surface of the guide portion 311 near the groove wall of the receiving groove 325 in the first direction is planar. In a reference section perpendicular to the second direction, the outline of the groove wall of the second groove segment 3252 is parallel to the outer surface of the guide portion 311 near the groove wall of the receiving groove 325 in the first direction. For example, the extension direction of the second groove segment 3252 is not parallel to the second direction. In a reference section parallel to the second direction, the outline of the second groove segment 3252 is a straight line or a curve, meaning the cross-sectional area of ​​the receiving groove 325 increases continuously, linearly or non-linearly, in the direction in which the locking member 31 moves from the first position to the second position. Alternatively, the extension direction of the second groove segment 3252 is parallel to the second direction. In a reference section parallel to the second direction, the outline of the second groove segment 3252 is stepped, meaning the cross-sectional area of ​​the receiving groove 325 increases discontinuously, in a stepped manner, in the direction in which the locking member 31 moves from the first position to the second position. This configuration allows the groove wall of the second groove segment 3252 to be a plane or a cylindrical curved surface, and the shape of the groove wall of the receiving groove 325 to be relatively regular, facilitating the machining of the receiving groove 325.

[0033] The increased gap between at least a portion of the outer wall of the guide portion 311 and the wall of the receiving groove 325 allows foreign objects to move with the locking member 31 and fall to the bottom of the receiving groove 325, thereby enabling the housing assembly 20 to be opened for cleaning. In one embodiment, as... Figure 6 , Figure 10 , Figure 11As shown, the movable component 32 also has a drain channel 326, which extends along a third direction and communicates with the receiving groove 325 on one side of the receiving groove 325 in the first direction. The drain channel 326 can be located on one side of the receiving groove 325 in the first direction, or it can be located on both sides of the receiving groove 325 in the first direction. The drain channel 326 can penetrate the movable component 32 along the third direction, or it can only penetrate one side of the movable component 32. The side wall of the drain channel 326 away from the key hole 221 in the second direction can be lower than the bottom wall of the receiving groove 325; or, the side wall of the drain channel 326 away from the key hole 221 in the second direction can be flush with the bottom wall of the receiving groove 325, so that foreign objects can collect in the drain channel 326 under the action of gravity. In contrast, by setting the sidewall of the drain channel 326 away from the keyhole 221 in the second direction to be flush with the bottom wall of the receiving groove 325, the size of the drain channel 326 in the second direction can be reduced, which is beneficial to reducing the size of the moving part 32. By setting the drain channel 326 that communicates with the receiving groove 325, and by setting the sidewall of the drain channel 326 away from the keyhole 221 in the second direction to be flush with the bottom wall of the receiving groove 325, foreign objects can be collected in the drain channel 326 under the action of gravity, thereby facilitating the cleaning of foreign objects.

[0034] Please see Figure 11 In one embodiment, the housing assembly 20 has a drain hole 222 on a third-direction side, which can communicate with the drain channel 326. For example, the drain hole 222 can be positioned offset at one end of the button hole 221 in the first direction. When the movable member 32 slides to a preset position, it can communicate with the drain channel 326, allowing foreign objects in the drain channel 326 to be discharged from the drain hole 222 by rinsing or suction. Since foreign objects can be cleaned without opening the housing assembly 20, it is beneficial to improve the user experience.

[0035] The drain hole 222 can be sealed by the housing of the main body 200 to prevent external foreign objects from entering the drain channel 326 through the drain hole 222. Or, as Figure 11 As shown, in one embodiment, the housing assembly 20 includes a seal 25 for sealing the drain hole 222. The seal 25 can be a label or a rubber stopper. By providing the seal 25, even when the battery device 100 is separated from the device body 200, the seal 25 can prevent external foreign objects from entering the drain channel 326 from the drain hole 222, further reducing the possibility of foreign objects entering the drain channel 326.

[0036] Please see Figure 3 , Figure 5 , Figure 6 , Figure 10In one embodiment, the housing assembly 20 includes a housing 21, an end cap 22, and a fixing member 23. The battery assembly 10 is mounted on the housing 21, and the end cap 22 is disposed at one end of the housing 21. The end cap 22, the housing 21, and the fixing member 23 enclose a sliding cavity 27. The housing 21 may include multiple sub-housings to enclose an installation space for the battery assembly 10. The end cap 22 may be integrally formed with the housing 21 or assembled with the housing 21. Similarly, the two limiting members 24 may be integrally formed with the housing 21 and the end cap 22 respectively, or may be assembled with them. A button hole 221 is provided on the end cap 22. The button hole 221 may be provided in the middle region of the end cap 22 in a first direction, making the appearance of the battery device 100 more aesthetically pleasing. The fixing member 23 is provided with a limiting groove 231. The movable component 32 includes a slider 322, a push button 321, and a locking claw 323. The push button 321 and the locking claw 323 are respectively connected to the slider 322. The push button 321 passes through the button hole 221. A receiving groove 325 is disposed at the push button 321 along the second direction. A portion of the receiving groove 325 extends through the slider 322. The locking claw 323 passes through the limiting groove 231 and is used to detachably install the battery device 100 to the electronic device 500. Exemplarily, the push button 321 and the locking claw 323 can be respectively connected to opposite sides of the slider 322 in the second direction, thereby making full use of the space at the end of the housing 21. The locking claw 323 can be hook-shaped, and a corresponding through hole is provided on the main body 200. When the locking member 31 is in the first position, the locking part 312 restricts the sliding of the movable member 32, and the locking claw 323 can be inserted into the through hole to fix the battery device 100 to the main body 200 to prevent the battery device 100 from falling off. When the locking member 31 is in the second position, the locking part 312 unlocks the movable member 32, and the movable member 32 can be pushed to slide in the first direction by the push knob 321. The locking claw 323 slides out from the through hole, so that the locking claw 323 is unlocked from the main body 200, and the battery device 100 can be removed from the main body 200.

[0037] In one embodiment, such as Figure 3 , Figure 8As shown, the locking assembly 30 includes a first elastic member 33. The first elastic member 33 may be a spring or an elastic rubber component. The first elastic member 33 is accommodated in a receiving groove 325, and its two ends abut against the guide portion 311 and the sliding body 322, respectively. When the battery device 100 needs to be removed from the main body 200, the guide part 311 can be pressed to make the locking member 31 be in the second position. The locking part 312 separates from the limiting member 24 on one side in the first direction. The first elastic member 33 is elastically compressed and exerts pressure on the locking part 312. The locking part 312 abuts against the limiting member 24 on one side in the second direction, which can prevent the movable member 32 from shaking when sliding along the first direction, thereby making the movement of the movable member 32 more stable. When the battery device 100 needs to be fixed to the main body 200, after the movable member 32 moves to the predetermined position in the sliding cavity 27, the locking part 312 separates from the limiting member 24 on one side in the second direction, so that the first elastic member 33 can drive the locking member 31 to move to the first position in the second direction. The locking part 312 abuts against the limiting member 24 on one side in the first direction, and the locking part 312 locks the movable member 32 to the housing assembly 20.

[0038] In one embodiment, such as Figure 8 As shown, the movable component 32 also includes a positioning post 324, which is connected to the sliding body 322. The positioning post 324 extends along the second direction, and the first elastic member 33 is sleeved on the positioning post 324. The positioning post 324 can restrict the displacement of the first elastic member 33, thereby preventing the locking member 31 from deviating when moving from the first position to the second position, making the movement of the locking member 31 more stable.

[0039] Sliding friction can exist between the moving part 32 and the cavity wall of the sliding cavity 27. The relatively smooth cavity wall of the sliding cavity 27 reduces the resistance to sliding of the moving part 32 within it. Alternatively, please refer to... Figure 3 , Figure 8 In one embodiment, the moving member 32 and the cavity wall of the sliding cavity 27 experience rolling friction. The locking assembly 30 includes a ball bearing 34 and a second elastic member 35. A mounting groove 3221 is provided on the sliding body 322, and the second elastic member 35 is disposed in the mounting groove 3221. The two ends of the second elastic member 35 abut against the sliding body 322 and the ball bearing 34 respectively, causing the ball bearing 34 to abut against the fixing member 23. By setting the sliding body 322 to abut against the fixing member 23 via the ball bearing 34, a rolling contact is formed between the sliding body 322 and the fixing member 23, which can further reduce the resistance when the moving member 32 slides in the sliding cavity 27.

[0040] In one embodiment, such as Figure 3 , Figure 8As shown, a base plate 26 is mounted on the fixing member 23, and the base plate 26 can be embedded in the fixing member 23. A limiting position 261 is provided on the base plate 26. The ball 34 rolls on the base plate 26, and when the ball 34 falls into the limiting position 261, the locking claw 323 unlocks from the device body 200.
