[0043] The embodiment of the utility model discloses a handheld device and a battery cover for convenient battery replacement.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] In some embodiments, see Figures 1-6 The battery cover 1 provided by the present invention comprises a cover body 11, a screw cap 12 and a handle 13. The cover body 11 is used to insert into the opening 201 of the battery compartment 2 of the handheld device. The structure of the battery compartment 2 can be referred to Figure 7-Figure 9 The shape of the cover 11 can be configured accordingly to the shape of the opening 201 of the battery compartment 2 so as to close the opening 201 when assembled. The screw cap 12 is rotatably disposed on the side of the cover 11 facing the battery compartment 2. The screw cap 12 has a snap-fit ​​portion 121 for engaging with the snap-fit ​​slot 202 on the battery compartment 2. The screw cap 12 can rotate between a first position and a second position.

[0046] The handle 13 is rotatably disposed on a side of the cover 11 away from the battery compartment 2 and is connected to the rotary cover 12. Positioning the rotary cover 12 on the inside of the cover 11 prevents the cover 12 from being exposed when the cover 11 is inserted into the opening 201 of the battery compartment 2, thereby enhancing the appearance of the handheld device. Furthermore, by providing the handle 13 and connecting it to the rotary cover 12, the user can rotate the handle 13 on the outside of the cover 11 to drive the rotary cover 12 on the inside of the cover 11. The shape of the handle 13 can be customized and is not limited herein. Specifically, the handle 13 can be a rod that defines a cavity for the user to grasp, such as a U-shaped, C-shaped, or L-shaped rod. Alternatively, the handle 13 can be a protrusion, such as a protrusion disposed within the arc-shaped through-hole 111, so that the protrusion moves along the through-hole 111 when the rotary cover 12 rotates. It is understandable that the handle 13 and the rotary cover 12 can be different components and connected directly or indirectly using conventional fixing methods to facilitate the overall assembly of the battery cover 1. Alternatively, the handle 13 and the rotary cover 12 can also be an integrated structure if the assembly requirements are met.

[0047] The handle 13 is used to receive an external force and drive the rotary cover 12 to rotate. When the handle 13 drives the rotary cover 12 to rotate to the first position, the engaging portion 121 is inserted into the slot 202 to lock the battery cover to the battery compartment 2. When the handle 13 drives the rotary cover 12 to rotate to the second position, the engaging portion 121 is withdrawn from the slot 202 to unlock the battery cover. It is understood that the shape of the engaging portion 121 can be configured accordingly to the shape of the slot 202, and the rotary cover 12 can rotate between the engaging portion 121 being inserted into the slot 202 and withdrawn from the slot 202. The engagement of the engaging portion 121 with the slot 202 connects the cover 11 to the battery compartment 2, preventing it from falling out of the battery compartment 2, thereby achieving a secure connection of the cover 11. Specifically, the extending direction of the card slot 202 can be perpendicular to the insertion direction of the cover body 11. The engaging portion 121 accordingly adopts a horizontal plate. When it is inserted into the card slot 202, the engaging surface with the card slot 202 is larger and the engaging is reliable.

[0048] With the battery cover 1 provided by the present invention, the cover body 11 can be inserted into the opening 201 of the battery compartment 2 to close the opening 201. After the cover body 11 is assembled in place, the user can rotate the handle 13 to drive the rotary cover 12 to rotate, so that the engaging portion 121 of the rotary cover 12 rotates to the first position, that is, the engaging portion 121 is inserted into the engaging slot 202 of the battery compartment 2, thereby achieving a reliable connection between the battery cover 1 and the battery compartment 2. Figure 7 When the battery needs to be replaced, the user can rotate the handle 13 in the opposite direction to drive the rotary cover 12 to rotate in the opposite direction. When the engaging portion 121 rotates to the second position, the engaging portion 121 is ejected from the slot 202. Figure 8As shown, the locking action with the battery compartment 2 is released, and the battery cover 1 can be pulled out through the opening 201 of the battery compartment 2 to replace the battery. In summary, the battery cover 1 provided in this application can be disassembled and assembled with one hand without the need for tools, greatly facilitating battery replacement, and is particularly suitable for outdoor environments, thereby improving the user experience.

[0049] In some embodiments, see Figure 4 and Figure 5 The rotary cover 12 includes a square or rectangular main body, with engaging portions 121 formed as arched sections at opposite ends of the main body. The chord length of the arched sections is equal to the length of the corresponding side of the main body. When the rotary cover 12 is rotated to the first position, the arched sections insert into the engaging slots 202, locking the battery cover 1 in the battery compartment 2. When the rotary cover 12 is rotated to the second position, the side of the main body not connected to the arched section faces the engaging slots 202, i.e., the arched sections exit the engaging slots 202, unlocking the battery cover 1. This arrangement of the rotary cover 12 provides a simple structure.

[0050] In some embodiments, the cover body 11 is provided with a through hole 111, and the handle 13 and the rotary cover 12 are connected through the through hole 111. By providing the through hole 111, the handle 13 or the rotary cover 12 can be inserted into the through hole 111, or the handle 13 and the rotary cover 12 can be inserted into the through hole 111 from both ends to achieve the connection between the handle 13 and the rotary cover 12, and the overall structure is simple and compact.

[0051] In some embodiments, the battery cover 1 further includes a central sleeve 14. The central sleeve 14 and the handle 13 are located on the same side of the cover 11. The central sleeve 14 or a portion of the rotary cover 12 is inserted through the through-hole 111 and is fixedly connected to the rotary cover 12. The handle 13 is rotatably mounted on the central sleeve 14, with the rotation axis of the handle 13 being perpendicular to the rotation axis of the rotary cover 12. The handle 13 is connected to the rotary cover 12 via the central sleeve 14. When the handle 13 rotates, the central sleeve 14 rotates, which in turn rotates the rotary cover 12, thereby switching the rotary cover 12 between the first position and the second position, thereby locking and unlocking the cover 11 and the battery compartment 2. The central sleeve 14 and the rotary cover 12 are located on both sides of the cover 11. The central sleeve 14 or a portion of the rotary cover 12 is inserted through the through-hole 111 of the cover 11, thereby fixing the central sleeve 14 and the rotary cover 12. The handle 13 is rotatably mounted on the central sleeve 14, with the rotation axis of the handle 13 perpendicular to the rotation axis of the rotary cover 12. For ease of explanation, the direction of the rotation axis of the rotary cover 12 relative to the cover body 11 is referred to as the first direction, and the direction of the rotation axis of the handle 13 relative to the central sleeve 14 is referred to as the second direction. On the one hand, rotation of the handle 13 in the first direction can drive the rotary cover 12 to rotate in the first direction. On the other hand, the handle 13 can also be rotated in the second direction to either stand upright or lay flat. Therefore, when the battery needs to be replaced, the handle 13 can first be rotated in the second direction to stand upright. Once upright, the user can apply force to rotate the handle 13 in the first direction, thereby unlocking the rotary cover 12. Once the battery is replaced and the rotary cover 12 is rotated to engage with the latch slot 202, the handle 13 can be laid flat. This not only reduces space usage but also makes it less likely to be accidentally touched, reducing the risk of the battery cover 1 accidentally falling out of the battery compartment 2.

[0052] In some embodiments, see Figure 1-Figure 3 The top surface of the cover body 11 is provided with a mounting groove 112, and the central sleeve 14 is disposed in the mounting groove 112. The handle 13 can rotate relative to the central sleeve 14 until it is accommodated in the mounting groove 112 or protrudes from a notch 113 of the mounting groove 112. By providing the mounting groove 112 on the top surface of the cover body 11, an accommodating space is provided for the central sleeve 14 and the handle 13. When the handle 13 rotates about the second direction to be accommodated in the mounting groove 112, the handle 13 does not protrude from the notch 113 of the mounting groove 112. That is, the handle 13 is located within the notch 113 of the mounting groove 112 or is parallel to the notch 113 of the mounting groove 112. This makes it difficult for the handle 13 to be accidentally touched, thereby preventing the battery cover 1 from accidentally falling off the battery compartment 2.

[0053] Furthermore, a limiting groove is formed between the cover 11 and the central sleeve 14, which is in the same shape as the handle 13. When the handle 13 is placed flat in the limiting groove, it cannot rotate in the first direction due to the limiting effect of the cover 11 and the central sleeve 14, further avoiding misoperation of the rotary cover 12. When the rotary cover 12 needs to be rotated, the handle 13 is first turned up in the second direction. The rotation of the handle 13 in the first direction is no longer restricted, so the user can drive the rotary cover 12 to rotate by turning the handle 13. For details, please refer to Figure 5 A flange 132 is provided in the middle of the handle 13, and an avoidance space is provided on the cover body 11 corresponding to the flange 132. When the middle sleeve 14 rotates to the first position with the rotary cover 12, a limiting groove with the same shape as the handle 13 is formed between the cover body 11 and the middle sleeve 14. The arrangement of the flange 132 and the avoidance space can not only limit the handle 13, but also serve as a prompt to the user to indicate that the rotary cover 12 is in the first position.

[0054] In some embodiments, see Figure 4-Figure 6 The battery cover 1 further includes a pressing plate 15 and an elastic member 16. The pressing plate 15 is rotatably mounted on the central sleeve 14, and the rotation axis of the pressing plate 15 is coaxial with the rotation axis of the handle 13 relative to the central sleeve 14. One end of the pressing plate 15 is provided with a pushing portion 151, which is located below the handle 13 and abuts against the handle 13. The elastic member 16 is disposed between the other end of the pressing plate 15 and the central sleeve 14 and is used to provide a force to move the other end of the pressing plate 15 away from the central sleeve 14. By providing the pressing plate 15 and the elastic member 16, in a natural state, the elastic member 16 acts on the pressing plate 15. Under the action of a lever, the end of the pressing plate 15 provided with the pushing portion 151 is in a downwardly pressed state, i.e., close to or in contact with the central sleeve 14. At this time, the handle 13 can be accommodated in the mounting groove 112. When the handle 13 needs to be rotated, the user presses the end of the pressure plate 15 that engages with the elastic member 16. Under the action of the lever, the end of the pressure plate 15 provided with the pushing portion 151 is lifted upward and pushes the handle 13 to rotate in the second direction, that is, the handle 13 is tilted, so that the user can easily operate the handle 13 to further rotate it to the upright position. The handle 13 is stored in the installation slot 112 to avoid accidental touch. When the rotary cover 12 needs to be rotated, the handle 13 needs to be flipped up. With the setting of the pressure plate 15, the user does not need to buckle the handle 13 from the edge of the handle 13. By pressing the pressure plate 15, the handle 13 will be tilted to a certain height, specifically protruding from the notch 113 of the installation slot 112, which greatly facilitates user operation. After releasing the pressure plate 15, the pressure plate 15 will automatically reset under the action of the elastic member 16.

[0055] In some embodiments, the central sleeve 14 is provided with a first axial hole 141, the pressure plate 15 is provided with a second axial hole 152, and the handle 13 is provided with a third axial hole 131. A pin 17 is provided within the first axial hole 141, the second axial hole 152, and the third axial hole 131. The pin 17 has a clearance fit with the first axial hole 141 and the second axial hole 152, and an interference fit with the third axial hole 131. The connection between the pressure plate 15, the central sleeve 14, and the handle 13 is achieved through the pin 17, resulting in a simple structure and easy assembly. Rotation of the handle 13 in a first direction can drive the central sleeve 14 to rotate in the first direction accordingly via the pin 17, thereby driving the rotary cover 12 to rotate in the first direction simultaneously. Furthermore, the clearance fit between the pin 17 and the first axial hole 141 and the second axial hole 152 ensures smooth lifting and lowering of the handle 13.

[0056] In some embodiments, one of the rotary cover 12 and the cover body 11 is provided with an arcuate groove 122, and the other is provided with a stop protrusion 114. The stop protrusion 114 is inserted into the arcuate groove 122. When the rotary cover 12 is rotated until the stop protrusion 114 abuts against one end of the arcuate groove 122, the rotary cover 12 is in a first position. When the rotary cover 12 is rotated until the stop protrusion 114 abuts against the other end of the arcuate groove 122, the rotary cover 12 is in a second position. In one embodiment, the rotary cover 12 is provided with an arcuate groove 122 and the cover body 11 is provided with a stop protrusion 114. In another embodiment, the cover body 11 is provided with an arcuate groove 122 and the rotary cover 12 is provided with a stop protrusion 114. By providing an arcuate groove 122 on one of the mating surfaces of the cover body 11 and the rotating cover 12, and providing a limiting protrusion 114 on the other, the limiting protrusion 114 is inserted into the arcuate groove 122. When the rotating cover 12 rotates in a first direction, it can serve as a limiting guide. The length of the arcuate groove 122 is set to limit the rotation angle of the rotating cover 12. That is, when the rotating cover 12 rotates until the limiting protrusion 114 abuts one end of the arcuate groove 122, the rotating cover 12 is in the first position. When the rotating cover 12 rotates until the limiting protrusion 114 abuts the other end of the arcuate groove 122, the rotating cover 12 is in the second position. Specifically, the central angle of the arcuate groove 122 is 90 degrees, and the rotating cover 12 can rotate within a range of 90 degrees.

[0057] In some embodiments, a first annular groove 123 is provided on the end surface of the rotary cover 12 facing the central shaft sleeve 14. The inner diameter of the first annular groove 123 is larger than the outer diameter of the through hole 111. A first sealing ring 18 is provided in the first annular groove 123. The first sealing ring 18 abuts against the end surface of the cover body 11 with the through hole 111 to seal. In other embodiments, a first annular groove 123 is provided on the end surface of the cover body 11 facing the rotary cover 12. The inner diameter of the first annular groove 123 is larger than the outer diameter of the through hole 111. A first sealing ring 18 is provided in the first annular groove 123. The first sealing ring 18 abuts against the end surface of the rotary cover 12 facing the central shaft sleeve 14. By providing a first annular groove 123 on the rotary cover 12 or the cover body 11 and installing the first sealing ring 18 therein, it can be understood that the thickness of the first sealing ring 18 should be greater than the depth of the first annular groove 123, so that the first sealing ring 18 is squeezed between the end face of the through hole 111 provided in the cover body 11 and the central shaft sleeve 14 to achieve sealing, thereby preventing external dust, liquid, etc. from entering the inner side of the cover body 11.

[0058] In some embodiments, the sidewall of the cover 11 is provided with a second annular groove 115, within which a second sealing ring 19 is disposed. The second sealing ring 19 is configured to abut against the inner wall of the battery compartment 2 to provide a seal. It is understood that the thickness of the second sealing ring 19 should be greater than the depth of the second annular groove 115, so that the second sealing ring 19 is squeezed between the outer circumference of the cover 11 and the battery compartment 2 to achieve a seal, thereby preventing external dust, liquid, and the like from entering the battery compartment 2. The provision of the second sealing ring 19, combined with the provision of the first sealing ring 18, effectively seals the battery cover 1 and the battery compartment 2, meeting waterproof requirements for outdoor use.

[0059] In some embodiments, a receiving groove 116 is provided at the end of the cover 11 facing away from the handle 13. The rotary cover 12 is disposed within the receiving groove 116. The sidewalls of the receiving groove 116 are provided with a relief hole 117. When the rotary cover 12 is rotated to the first position, the engaging portion 121 passes through the relief hole 117 to engage with the engaging groove 202 of the battery compartment 2. By configuring the shape of the cover 11 to form the receiving groove 116 and positioning the rotary cover 12 within the receiving groove 116, the battery cover 1 has a more regular appearance and the cover 11 can better fit the battery compartment 2. Specifically, the sidewalls of the cover 11 form the receiving groove 116, and the relief hole 117 is provided on the sidewalls.

[0060] In some embodiments, a circuit board 20 is provided in the accommodating groove 116, and an electrical connector 21 for electrically connecting to the battery is provided on the circuit board 20. The notch 113 of the accommodating groove 116 is provided with a decorative cover 22, and a position-avoiding through hole 221 is provided on the decorative cover 22. The electrical connector 21 is passed through the position-avoiding through hole 221. The circuit board 20 is used to connect to the battery, and its specific structure can refer to the setting of a conventional battery cover and is not specifically limited here.
