DETAILED DESCRIPTION

[0046] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0047] The words expressing positions and directions described in the present invention are all explained with reference to the accompanying drawings as examples, but they can be changed as needed, and all such changes are included in the protection scope of the present invention.

[0048] like Figure 1 As shown, the present invention provides a quick-release device, comprising a first shell 1, a second shell 2, and a quick-release assembly for realizing quick disassembly and assembly between the first shell 1 and the second shell 2. The quick-release device of the present invention can be applied to a device so that a component in the device can be separated from a main body of the device or installed in the main body of the device. The main body shell of the device can form the first shell 1, and the shell of the component to be disassembled in the device can form the second shell 2. The quick-release device realizes the installation and removal between the component and the main body of the device by locking and releasing the first shell 1 and the second shell 2.

[0049] Reference Figure 2 The first shell 1 may be provided with an installation chamber 11 for installing a quick-release assembly, and a through hole 12 that penetrates the first shell 1 and can communicate with the installation chamber 11. When the first shell 1 and the second shell 2 are locked, the main part of the quick-release assembly is accommodated in the installation chamber 11 of the first shell 1, and the part of the quick-release assembly used to cooperate with the second shell 2 can extend out of the first shell 1 through the through hole 12. When it is necessary to separate the first shell 1 from the second shell 2, the quick-release assembly can be completely accommodated in the installation chamber 11, or the quick-release assembly can be completely accommodated in the overall space composed of the installation chamber 11 and the through hole 12. Among them, one or more through holes 12 can be provided, and the part of the quick-release assembly used to cooperate with the second shell 2 can extend out of the first shell 1 through one or more through holes 12.

[0050] In some specific embodiments, a receiving chamber 16 for receiving the second housing 2 may be further provided in the first housing 1, and the receiving chamber 16 may be communicated with the through hole 12. The contour of the receiving chamber 16 may be adapted to the outer contour of the second housing 2, so that when the second housing 2 is received in the receiving chamber 16, the second housing 2 may completely fill the receiving chamber 16, or fill most of the area of ​​the receiving chamber 16 and leave a small space with the wall forming the receiving chamber 16.

[0051] The second housing 2 is provided with a limiting groove 21. When the second housing 2 is installed in the first housing 1, the limiting groove 21 of the second housing 2 can be communicated with the through hole 12 of the first housing 1, so that the part of the quick release component extending from the first housing 1 can extend into the limiting groove 21 and abut against the wall forming the limiting groove 21, thereby limiting the relative movement between the second housing 2 and the first housing 1 to lock the second housing 2. There can be one limiting groove 21, and one limiting groove 21 can be correspondingly communicated with multiple or all through holes 12, so that part of the quick release component extending from the through hole 12 corresponding to the limiting groove 21 can extend into the limiting groove 21; or, there can be multiple limiting grooves 21, and each limiting groove 21 can be correspondingly communicated with one or more through holes 12, so that part of the quick release component extending from the through hole 12 corresponding to a limiting groove 21 can extend into the corresponding limiting groove 21.

[0052] The quick release assembly includes a first locking member 3, a second locking member 5 and a driving member 4. The first locking member 3 can be installed in the installation chamber 11. Figure 2 When the first housing 1 and the second housing 2 need to be locked, one end of the first locking member 3 can extend out of the first housing 1 through the corresponding through hole 12 and extend into the limiting groove 21 of the second housing 2. The portion of the first locking member 3 extending into the limiting groove 21 can abut against the wall forming the limiting groove 21 to lock the second housing 2. Figure 3 When the first shell 1 needs to be separated from the second shell 2, the first locking member 3 can be retracted into the first shell 1 to release the restriction on the second shell 2, and the second shell 2 can be separated from the first shell 1. The first locking member 3 is used to extend out of the first shell 1 to form a limiting portion 32, and the limiting portion 32 extends into the limiting groove 21 of the second shell 2. When the second shell 2 is installed in the first shell 1, the second shell 2 can move along the installation direction of the second shell 2 to abut against the inner wall of the first shell 1, thereby preventing the second shell 2 from moving further along its installation direction; when the second shell 2 moves in the direction opposite to its installation direction, the second shell 2 will abut against the limiting portion 32 of the first locking member 3 to be restricted by the first locking member 3, thereby locking the second shell 2 in the first shell 1.

[0053] Reference Figure 3 and Figure 6The driving member 4 can be connected to the first locking member 3 and used to drive the first locking member 3 to move, so that the first locking member 3 can be retracted into the first housing 1 under the drive of the driving member 4. When the driving member 4 drives the first locking member 3 to move, the moving direction of the driving member 4 is the first direction, and the moving direction of the first locking member 3 when retracting is the second direction, and the first direction can be perpendicular to the second direction. After the driving member 4 drives the first locking member 3 to retract into the first housing 1, the driving member 4 is in the release position; when the driving member 4 moves to the initial position in the opposite direction of the first direction, the driving member 4 is in the locking position.

[0054] Reference Figure 8 and Fig.10 Specifically, the driving member 4 may be provided with a second driving inclined surface 44, and the second driving inclined surface 44 is gradually lowered along the first direction. The second driving inclined surface 44 may abut against the first locking member 3, specifically, abut against the portion of the first locking member 3 accommodated in the installation chamber 11. When the driving member 4 moves along the first direction, the second driving inclined surface 44 drives the first locking member 3 to gradually rise, and the direction in which the first locking member 3 rises is the second direction, so that the first locking member 3 can be retracted into the first housing 1 under the drive of the driving member 4.

[0055] In some specific embodiments, in order to make the driving member 4 drive the first locking member 3 to move more smoothly and stably, the first locking member 3 is provided with a second mating bevel 33 mating with the second driving bevel 44, the second mating bevel 33 is parallel to the second driving bevel 44, and the first locking member 3 abuts against the second driving bevel 44 through the second mating bevel 33, so that the driving member 4 and the first locking member 3 maintain surface-to-surface contact during relative movement, thereby improving the stability of the relative movement of the driving member 4 and the first locking member 3.

[0056] In some specific embodiments, in order to allow the first locking member 3 to retract into the first shell 1 after the driving member 4 drives the first locking member 3 to retract, so that the first locking member 3 can re-extend from the first shell 1 to lock the second shell 2, the first locking member 3 can be connected to a third elastic member 31. One end of the third elastic member 31 directly or indirectly abuts against the wall forming the installation chamber 11, and the other end directly or indirectly abuts against the first locking member 3. When the first locking member 3 retracts into the first shell 1 driven by the driving member 4, the first locking member 3 will squeeze the third elastic member 31 and cause the third elastic member 31 to be compressed. At this time, the third elastic member 31 applies an elastic force to the first locking member 3 extending toward the first shell 1, so that the first locking member 3 can re-extend from the first shell 1 under the drive of the third elastic member 31. Among them, the third elastic member 31 can be specifically a spring.

[0057] In some specific embodiments, when the second shell 2 is taken out, the driving member 4 can be kept in the released position and the first locking member 3 can be kept retracted into the first shell 1. When the second shell 2 is inserted into the first shell 1 again, the driving member 4 can be moved to the locked position, and the first locking member 3 can be extended out of the first shell 1 under the drive of the third elastic member 31.

[0058] Reference Figure 2 and Figure 5 In other specific embodiments, when the second shell 2 is taken out, the driving member 4 can be moved to the locking position, and the first locking member 3 is extended out of the first shell 1 under the drive of the third elastic member 31. In order to prevent the second shell 2 from interfering with the first locking member 3 when it needs to be installed in the first shell 1, the limiting portion 32 of the first locking member 3 can include an installation bevel 321 and a locking surface 322 located in front of the installation bevel 321 along the installation direction of the second shell 2. The height of the installation bevel 321 gradually decreases along the installation direction of the second shell 2. When the second shell 2 is installed in the first shell 1, the second shell 2 will first contact the installation bevel 321, and lift the first locking member 3 through the installation bevel 321, so that the first locking member 3 is retracted into the first shell 1. When the second housing 2 is installed, the limiting groove 21 of the second housing 2 is located below the limiting portion 32 of the first locking member 3, and the limiting portion 32 of the first locking member 3 can extend into the limiting groove 21 under the drive of the third elastic member 31, and the locking surface 322 of the limiting portion 32 can abut against the wall forming the limiting groove 21 to limit the movement of the second housing 2. The locking surface 322 can be parallel or substantially parallel to the side wall forming the limiting groove 21, specifically, the locking surface 322 is parallel or substantially parallel to the side wall of the side wall forming the limiting groove 21, which is located at the front end along the installation direction of the second housing 2, and is used to abut against the side wall.

[0059] Reference Figure 7 and Fig. 9 When the driving member 4 moves to the release position, it is necessary to keep the driving member 4 at the release position for a period of time to facilitate the removal of the second housing 2. In order to keep the driving member 4 fixed when it moves to the release position, the driving member 4 is connected to the second locking member 5. Specifically, the driving member 4 can be provided with a locking groove 41, and the second locking member 5 is provided with a locking portion 51 corresponding to the locking groove 41. Fig. 9, when the driving member 4 drives the first locking member 3 to retract, the locking portion 51 of the second locking member 5 can face the locking groove 41, for example, the projection of the locking portion 51 of the second locking member 5 along the opposite direction of the second direction completely falls into the locking groove 41, preferably, the locking portion 51 is located directly above the locking groove 41. At this time, the locking portion 51 of the second locking member 5 can fall into the locking groove 41 by external force or deadweight, and the locking portion 51 can abut against the side wall forming the locking groove 41 to limit the movement of the driving member 4, thereby locking the driving member 4 in the release position. Among them, the moving direction of the second locking member 5 can be perpendicular to the moving direction of the driving member 4 and parallel to the moving direction of the first locking member 3; and when the driving member 4 moves, it drives the first locking member 3 and the second locking member 5 to move at the same time.

[0060] In some specific embodiments, in order to ensure the docking of the locking portion 51 with the locking groove 41, the second locking member 5 may be connected to a second elastic member 53. One end of the second elastic member 53 directly or indirectly abuts against the wall forming the installation chamber 11, and the other end of the second elastic member 53 directly or indirectly abuts against the locking portion 51 of the second locking member 5. When the driving member 4 moves to the release position, the second elastic member 53 is in a compressed state and will apply elastic force to the second locking member 5, and the locking groove 41 of the driving member 4 is located below the locking portion 51. At this time, the second elastic member 53 will drive the locking portion 51 to move toward the locking groove 41, thereby ensuring that the locking portion 51 can move into the locking groove 41 to achieve docking with the locking groove 41. Among them, the second elastic member 53 can be a spring.

[0061] In some specific embodiments, when the driving member 4 is in the locking position, the locking portion 51 of the second locking member 5 can abut against a plane that is higher than or flush with the upper end of the locking groove 41, and the second elastic member 53 maintains a state of large compression; when the driving member 4 moves to the release position, the locking portion 51 is flush with the upper end of the locking groove 41 or located above the locking groove 41, and the locking portion 51 of the second locking member 5 moves into the locking groove 41 driven by the second elastic member 53.

[0062] In some other specific embodiments, reference Figure 7When the driving member 4 is in the locking position, the locking portion 51 of the second locking member 5 can abut against the surface below the upper end of the locking groove 41, so that the second elastic member 53 maintains a state of small compression or no compression. In order to prevent the locking portion 51 from moving to be flush with the upper end of the locking groove 41 or above the locking groove 41, the driving member 4 can be provided with a first driving inclined surface 43 located in front of the locking groove 41 along the first direction, the height of the first driving inclined surface 43 gradually decreases along the first direction, and the highest point of the first driving inclined surface 43 can be flush with the upper end of the locking groove 41 or higher than the upper end of the locking groove 41. When the driving member 4 moves along the first direction, the locking portion 51 will gradually move to be higher than or flush with the upper end of the locking groove 41 under the drive of the first driving inclined surface 43. When the locking portion 51 is located above the locking groove 41, the locking portion 51 can be driven by the second elastic member 53 to move into the locking groove 41. The upper end of the locking groove 41 is the end of the locking groove 41 with the highest height in the direction opposite to the second direction.

[0063] In order to make the relative movement between the locking part 51 and the first driving bevel 43 more stable, the locking part 51 can be provided with a first mating bevel 511 mating with the first driving bevel 43. The first mating bevel 511 is parallel to the first driving bevel 43, and the locking part 51 abuts against the first driving bevel 43 through the first mating bevel 511, so that the locking part 51 and the first driving bevel 43 maintain surface-to-surface contact during movement, thereby improving the stability of the relative movement between the locking part 51 and the first driving bevel 43.

[0064] Reference Figure 2 and Figure 4When the driving member 4 needs to be moved to the locking position, the locking portion 51 needs to be moved out of the locking groove 41 so that the locking portion 51 releases the locking of the driving member 4. In order to facilitate the moving of the locking portion 51 out of the locking groove 41, a spherical portion 52 can be provided at one end of the second locking member 5. The spherical portion 52 can extend out of the first shell 1 through the through hole 12 and extend into the limiting groove 21, and the second shell 2 can drive the second locking member 5 to retract into the first shell 1 through the spherical portion 52 and move the locking portion 51 out of the locking groove 41 to release the locking of the driving member 4. Specifically, when the second shell 2 is installed in or removed from the first shell 1, the second shell 2 will abut against the spherical portion 52 of the second locking member 5, and lift the second locking member 5 through the spherical portion 52 during the movement, and the second locking member 5 will squeeze the second elastic member 53. When the second housing 2 is installed, the spherical portion 52 of the second locking member 5 can be located above the limiting groove 21 of the second housing 2, and the spherical portion 52 of the second locking member 5 is driven by the second elastic member 53 to move into the limiting groove 21. When the second housing 2 is moved out, the spherical portion 52 of the second locking member 5 can be driven by the second elastic member 53 to move into the accommodating chamber 16 for accommodating the second housing 2. The spherical portion 52 has a spherical structure, which can be a part of a spherical surface, such as a hemispherical surface or a 1 / 3 spherical surface. The spherical portion 52 and the limiting portion 32 can extend through one through hole 12, or the spherical portion 52 and the limiting portion 32 can extend through different through holes 12 respectively.

[0065] Reference Figure 6 In some specific embodiments, when the second locking member 5 releases the locking of the driving member 4, in order to realize that the driving member 4 automatically moves to the locking position, the driving member 4 may be connected to the first elastic member 42. One end of the first elastic member 42 directly or indirectly abuts against the wall forming the installation chamber 11, and the other end directly or indirectly abuts against the driving member 4, and the elastic force direction of the first elastic member 42 is parallel to the moving direction of the driving member 4. When the driving member 4 moves from the locking position to the release position, the first elastic member 42 is squeezed to make the first elastic member 42 compressed, and the driving member 4 is locked by the locking portion 51 of the second locking member 5 after moving to the release position, so that the first elastic member 42 remains in a compressed state; when the locking portion 51 of the second locking member 5 releases the locking of the driving member 4, the first elastic member 42 drives the driving member 4 to reset to the locking position.

[0066] Reference Fig.11 The present invention also provides a mobile power source, comprising the above-mentioned quick release device. The main body shell in the mobile power source forms a first shell 1 in the quick release device. The shell of the battery pack in the mobile power source forms a second shell 2 in the quick release device, and the second shell 2 accommodates the power module in the battery pack.

[0067] Reference Fig.12 and Fig.13 In order to facilitate the movement of the mobile power source, the first shell 1 may be connected with a handle 200, and the handle 200 is used for the user to hold it to facilitate the movement of the mobile power source. The handle 200 is provided with at least one first matching portion 201, and the first shell 1 is provided with at least one second matching portion 13. The first matching portion 201 and the second matching portion 13 may form a concave-convex matching, so that the handle 200 and the first shell 1 are relatively fixed through the cooperation of the first matching portion 201 and the second matching portion 13. Among them, the first matching portion 201 may be a groove, and the second matching portion 13 is provided with a protrusion 202 adapted to the groove; or, the second matching portion 13 is a groove, and the first matching portion 201 is provided with a protrusion 202 adapted to the groove. In this embodiment, specifically, the second matching portion 13 is a groove, and the first matching portion 201 is provided with a protrusion 202 adapted to the groove. The recessed direction of the groove can be perpendicular to the extension direction of the handle 200. When the first matching portion 201 is matched with the second matching portion 13, the protrusion 202 is accommodated in the groove, and the wall forming the groove blocks the protrusion 202 from moving along the extension direction of the handle 200, thereby keeping the handle 200 and the first shell 1 relatively fixed.

[0068] In order to allow the handle 200 to be extended when in use for user operation, and to be retracted when not in use to reduce the space occupied by the mobile power source, the handle 200 preferably forms a retractable structure with the first housing 1. Specifically, a plurality of second coupling portions 13 may be provided, and the plurality of second coupling portions 13 are arranged at intervals along the retracting direction of the handle 200. By matching the first coupling portion 201 with different second coupling portions 13, the handle 200 can be kept at different retracted positions, thereby realizing the retraction of the handle 200. When it is necessary to move the first connecting portion 201 of the handle 200 from one second connecting portion 13 to another second connecting portion 13, the user can apply a force to the handle 200 so that the portion of the handle 200 at the first connecting portion 201 is deformed in a direction away from the first shell 1, for example, the first connecting portion 201 of the handle 200 and the portion of the main body 204 of the handle 200 adjacent to the first connecting portion 201 are deformed, so that the first connecting portion 201 can be separated from the second connecting portion 13 under the action of an external force; when the first connecting portion 201 of the handle 200 is moved to another second connecting portion 13, the first connecting portion 201 of the handle 200 rebounds and makes the first connecting portion 201 mate with the second connecting portion 13.

[0069] When it is necessary to separate the first connection portion 201 from the second connection portion 13 by external force, the user needs to apply a large force to the handle 200 so that the portion of the handle 200 at the first connection portion 201 is deformed and then separated from the second connection portion 13. In order to reduce the force applied by the user when separating the first connection portion 201 from the second connection portion 13 for ease of operation, refer to Fig.14 The main body 204 of the handle 200 may be provided with a recessed groove 205, and the recessed groove 205 is used to accommodate the first matching portion 201. The first matching portion 201 is a plate-like structure, and a portion of the surface of the first matching portion 201 is protruded to form a protrusion 202. One end of the first matching portion 201 away from the protrusion 202 is connected to the main body 204, for example, forming an integrated structure with the main body 204. The first connecting portion 201, except for the portion connected to the main body 204, can be spaced apart from the main body 204 so that the first connecting portion 201 can be deformed under the action of an external force without interfering with the main body 204. Therefore, when the first connecting portion 201 needs to be separated from the second connecting portion 13, the main body 204 of the handle 200 can remain unchanged, while the first connecting portion 201 of the handle 200 is deformed and separated from the second connecting portion 13, so as to reduce the amount of deformation required for the handle 200, thereby reducing the force applied by the user when separating the first connecting portion 201 from the second connecting portion 13. The first connecting portion 201 can be completely accommodated in the recessed groove 205 when the first connecting portion 201 is separated from the second connecting portion 13 and deformed; when the first connecting portion 201 is mated with the second connecting portion 13, the protrusion 202 of the first connecting portion 201 at least partially protrudes out of the recessed groove 205 to mate with the second connecting portion 13, and the rest of the first connecting portion 201 can be accommodated in the recessed groove 205. The first connecting portion 201 has a certain elasticity so that the first connecting portion 201 can be elastically deformed. The main body 204 of the handle 200 can be specifically the part of the handle 200 except the first connecting portion 201 and the slider 203.

[0070] Reference Fig.13 In some specific embodiments, in order to facilitate the guidance of the telescopic movement of the handle 200, the first housing 1 may be provided with a slide groove 14, the extension direction of which is parallel to the telescopic direction of the handle 200. The handle 200 may be provided with a slider 203 that cooperates with the slide groove 14. When the handle 200 is installed in the first housing 1, the slider 203 of the handle 200 is at least partially disposed in the slide groove 14 of the first housing 1, so that the handle 200 can slide along the extension direction of the slide groove 14, thereby achieving guidance when the handle 200 is telescopic.

[0071] Reference Fig.11In some specific embodiments, in order to facilitate users to find the mobile power supply in a dim environment, a marking portion 15 may be provided on the surface of the first shell 1. A luminous layer is formed on the surface of the marking portion 15, and the luminous layer may be printed with luminous materials. When the mobile power supply is in a dim environment, the luminous layer may emit light to facilitate users to find it. In order to facilitate indicating the outline of the mobile power supply, the marking portion 15 may be provided at the edge of the first shell 1. Preferably, a plurality of marking portions 15 are provided, and each marking portion 15 is provided at an edge position of the first shell 1.
