[0004] 2. If the battery module is rotated to a removable state but the replacement battery is not connected in time, the electronic device will be powered off;

[0005] These defects will lead to a poor user experience of the equipment and will not be conducive to its use in emergency scenes. Utility Model Content

[0007] The technical solution adopted by the utility model to solve the technical problem is: construct a linkage type rotation limiting structure, which is applied to a first component and a second component that can rotate relatively, and the linkage type rotation limiting structure includes two rotation limiting structures arranged in linkage, and a limiting groove configured on the second component;

[0008] Any of the rotation limiting structures comprises a pry bar; the pry bar is arranged on a side of the first component facing away from the second component; the pry bar has a first end and a second end, the first end is located on a side of the first component facing away from the second component, the first end is used to connect to another rotation limiting structure, and the second end extends to a side of the first component facing the second component in a natural state, and retracts into the first component when subjected to an external force;

[0009] The two pry bars are hingedly connected through their respective first ends, and their respective second ends are linked to extend and retract together;

[0010] The linkage type rotation limiting structure includes a locked state and an unlocked state;

[0011] The locked state is that the second end of one of the two pry bars naturally extends into the limiting groove to limit the relative rotation range between the first component and the second component;

[0012] The unlocked state is that the other second end of the two pry bars is retracted into the first component under force, driving the second ends of the two pry bars extending into the limiting grooves to retract accordingly, so as to release the rotation restriction.

[0013] In some embodiments, any of the rotation limiting structures further comprises an elastic member for assisting the second end to extend from the first component to a side of the first component facing the second component;

[0014] One end of the elastic member is used for being fixedly connected to the first component, and the other end of the elastic member is connected to the pry bar.

[0015] In some embodiments, the limiting groove is a longitudinal arc groove.

[0016] In some embodiments, the two rotation limiting structures are arranged in mirror symmetry.

[0017] In some embodiments, the rotation limiting structure further includes a rotating shaft passing through the middle of the pry bar, and the pry bar can rotate around the rotating shaft, and the rotation plane is perpendicular to the first component.

[0018] In some embodiments, it includes a connection structure and the above-mentioned linkage type rotation limiting structure;

[0019] The connection structure comprises two through holes arranged on the first component, an insertion portion arranged on the second component, and a buckle structure; the insertion portion extends into one of the two through holes and is fixed in the through hole by the buckle structure;

[0020] The linkage type rotation limiting structure limits the disassembly rotation range between the first component and the second component, so that the second component rotates within the disassembly rotation range limited by the linkage type rotation limiting structure and remains connected to the first component through the buckle structure.

[0021] In some embodiments, the disassembly rotation range limited by the linked rotation limiting structure is smaller than the rotation range of the insertion portion disengaging from the through hole limited by the snap-fit ​​structure, so that before the new second component is connected to the first component through the other through hole of the two through holes and the second end of the pry bar is pushed back into the first component, the snap-fit ​​structure constrains the old second component to be connected to the first component.

[0022] In some embodiments, the snap-fit ​​structure includes blocking portions arranged on opposite sides of the through hole, and snap-fit ​​portions arranged on opposite sides of the insertion portion, and the two snap-fit ​​portions are configured to extend into the through hole from the spaced position between the two blocking portions, and are overlapped on the two blocking portions by rotation.

[0023] The utility model also constructs an electronic device, comprising a host module and a battery module, wherein the battery module is detachably mounted on one side of the host module, and the host module is provided with two connection positions which can be electrically connected to the battery module;

[0024] The electronic device also includes the above-mentioned anti-disconnection matching structure;

[0028] The implementation of the utility model has the following beneficial effects: the linkage rotation limiting structure of the utility model is suitable for assembling a first component and a second component that can rotate relative to each other; through the cooperation of the rotation limiting structure and the limit groove, the relative rotation angle between the first component and the second component can be limited to avoid unexpected results caused by large rotation angles.

[0029] For example, the linkage limited rotation structure can be applied to electronic devices, where the first component is a host module of the electronic device, and the second component is a battery module of the electronic device; by cooperating between the limited rotation structure arranged on the host module and the limiting groove arranged on the battery module, the relative rotation angle between the host module and the battery module of the electronic device can be limited, effectively preventing the electronic device from missing the disassembly opportunity during the replacement of the rotating battery module.

When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located on the other element, or there may be one or more intermediate elements. The terms "first", "second", "third", etc. are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0048] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details that hinder the description of the present invention.

[0049] See also Figure 1The utility model constructs a linkage type rotation limiting structure 1, which is suitable for assembling a first component 3 and a second component 4 that can rotate relatively. Through the rotation limiting structure 11, the relative rotation angle between the first component 3 and the second component 4 can be limited to avoid unexpected results caused by large rotation angles.

[0050] The following is an example in which the first component 3 and the second component 4 are flat plate structures, the first component 3 is located above the second component 4, and the first component 3 and the second component 4 need to be assembled and rotated to be fully fitted. Of course, the first component 3 and the second component 4 can be other shapes and structures, and the relative position between the first component 3 and the second component 4 can be adjusted, and whether they need to be fully fitted is not limited here.

[0051] In some embodiments, Figure 1 As shown, the linkage type rotation limiting structure 1 may include two rotation limiting structures 11 which are installed on the first component 3 and are arranged in linkage, and a limiting groove 12 which can be arranged on the second component 4 .

[0052] Optionally, see Figure 2 Any rotation limiting structure 11 includes a pry bar 111 , a rotating shaft 112 and an elastic member 113 .

[0053] The rotating shaft 112 is used to be fixed on the top surface of the first component 3 and is arranged in the middle of the pry bar 111. The pry bar 111 can rotate around the rotating shaft 112, and the plane of the rotation is perpendicular to the first component 3 and parallel to the length direction of the first component 3. Optionally, the rotating shaft 112 is a longitudinal cylindrical structure, and its length direction is perpendicular to the length direction of the first component 3.

[0054] The pry bar 111 has a first end and a second end, wherein the first end is located on one side of the top surface of the first component 3, and the second end can extend to one side of the bottom surface of the first component 3 in a natural state, and can be retracted into the first component 3 when subjected to external force. Optionally, the pry bar 111 is an L-shaped rod structure.

[0055] The elastic member 113 is used to help the pry bar 111 reset so that the second end of the pry bar 111 can be re-extended to one side of the bottom surface of the first component 3. Optionally, the elastic member 113 can be a torsion spring, one end of which is fixedly connected to the first component 3, and the other end of which is connected to the pry bar 111. Of course, the elastic member 113 is not a necessary component of the linkage type rotation limiting structure 1. In an embodiment where the elastic member 113 is not provided, the second end of the pry bar 111 can be re-extended under the action of gravity.

[0056] like Figure 1As shown, the limit groove 12 is a longitudinal arc groove for the second end of the pry bar 111 to extend into and relatively displace in the limit groove 12. The limit displacement position of the second end is limited by the groove wall of the limit groove 12 to limit the relative rotation angle between the first component 3 and the second component 4. The rotation angle corresponds to the length of the limit groove 12.

[0057] Combination Figure 1 , Figure 2 It can be seen that the two pry bars 111 are hinged through their respective first ends, and their respective second ends are linked to extend and retract together. The linkage type rotation limiting structure includes a locked state and an unlocked state.

[0058] In the locked state, the second end of one of the two pry bars 111 naturally extends into the limiting groove 12 to limit the relative rotation range between the first component 3 and the second component 4;

[0059] In the unlocked state, the other second end of the two pry bars 111 is retracted into the first component 3 under force, driving the second ends of the two pry bars 111 extending into the limiting grooves 12 to retract accordingly, so as to release the rotation restriction.

[0060] When the surface of the second component 4 applies force to the second end of any pry rod 111 to retract the second ends of the two pry rods 111 into the first component 3 , the linkage rotation limiting structure changes from a locked state to an unlocked state.

[0061] It can be understood that when the first component 3 and the second component 4 are separated, reference can be made to Figure 1 , the two pry bars 111 are in a natural state, and their respective second ends extend to one side of the bottom surface of the first component 3.

[0062] See also Figure 3 , during the installation process of the second component 4 and the first component 3, the second component 4 first partially contacts the first component 3, and at this time the position between them is not yet the preset assembly completion position (in the present embodiment, the preset assembly completion position is that the second component 4 is completely fitted to the first component 3), the top surface of the second component 4 pushes up the second end of one of the pry bars 111, the pry bar 111 rotates due to the external force, and its second end retracts into the first component 3, while the second end of the other pry bar 111 is also retracted into the first component 3 under the action of linkage; as the first component 3 and the second component 4 continue to rotate relative to each other, the assembly is completed, and at this time the limit groove 12 is located below the second end of one of the pry bars 111; since the top surface of the second component 4 continuously pushes up one of the pry bars 111, the second end of the pry bar 111 does not affect the relative rotation between the first component 3 and the second component 4 during the entire installation stage.

[0063] See also Figure 4Subsequently, when the second component 4 needs to be separated from the first component 3, the second component 4 is rotated in the direction of disassembly. After rotating at a preset angle, due to the loss of the force on the top surface of the second component 4 and under the action of the elastic member 113, the second ends of the two pry bars 111 are extended again, and the second end of one of the pry bars 111 falls into the limiting groove 12 and is in a locked state, and the function of the rotation limiting structure 11 takes effect.

[0064] When the first component 3 and / or the second component 4 is about to rotate too much, the wall of the limit slot 12 will abut against the second end of the pry bar 111 and stop the first component 3 and / or the second component 4 from rotating further. If the second component 4 needs to be removed, an upward force needs to be applied to the second end of the other pry bar 111 to retract it into the first component 3, so that the locked state can be switched to the unlocked state, thereby removing the second component 4.

[0065] It should be noted that, for the convenience of understanding and explanation, the present invention specifically defines the positions of components such as the pry bar 111, but in fact, the top surface of the first component 3 can be understood as the surface of the first component 3 facing away from the second component 4, and the top surface of the second plane can be understood as the surface of the second component 4 facing the first component 3, and so on. Therefore, the positions of components such as the pry bar 111 on the first component 3 / second component 4 can be understood with reference to the relative positions of the first component 3 and the second component 4, and are not specifically limited here.

[0066] In some embodiments, Figure 2 As shown, any pry bar 111 may include a rod portion 1111 , and a connecting portion 1112 and a contact portion 1113 respectively connected to two ends of the rod portion 1111 .

[0067] The rod portion 1111 is longitudinally elongated, and its length direction is parallel to / coincides with the length direction of the first component 3 .

[0068] The connecting portion 1112 is located between the rod portion 1111 and another pry bar 111, and is used to connect to the other pry bar 111; the connecting portion 1112 is also longitudinally shaped, and its length direction is parallel to / coincides with the length direction of the first component 3; the position of the first connecting portion 1112 can be higher than the position of the rod portion 1111 to facilitate rotation.

[0069] The contact portion 1113 is located on one side of the rod 1111 away from the other pry bar 111, and is used to extend outside the first component 3 to cooperate with the second component 4. The contact portion 1113 can be longitudinally shaped, and can form an angle with the rod 1111; in this embodiment, the angle is 90°.

[0070] See also Figure 5The utility model also constructs an anti-disconnection matching structure, which is suitable for assembling a first component 3 and a second component 4 that can rotate relatively, wherein the first component 3 needs to maintain a connection relationship and a replacement component 5 (see Fig.10 ) replace the second component 4. It should be noted that the above-mentioned anti-disconnection can be to prevent disconnection in mechanical connection or to prevent disconnection in electrical connection.

[0071] Secondly, the replacement part 5 and the second component 4 can be the same object, and the replacement part 5 replacing the second component 4 can be understood as the replacement of the old and new second component 4. Here, for the convenience of understanding and distinction, a new name is used for the new second component 4. Understandably, in the definition of new and old, the old second component 4 can be understood as the second component 4 that has been installed on the first component 3 and is to be replaced, and the new second component 4 can be understood as the spare second component 4 that is to be replaced with the first component 3.

[0072] For example, the anti-disconnection matching structure can be applied in the communication field, such as on a backpack device with an external battery. In the related technology, when the battery of the backpack device is replaced, the old battery will be removed and the new battery will not be installed yet, which will cause the host of the backpack device to lose power. After the new battery is replaced, the host will restart and a short black screen will appear in the on-site command center, which greatly affects the normal use and usage experience of the product and is not conducive to emergency on-site command and judgment. The anti-disconnection matching structure constructed in the utility model can be applied to the device to replace the old battery with the new battery without cutting off the power.

[0073] In some embodiments, Figure 5 As shown, the anti-disconnection matching structure may include a linkage limited rotation structure 1 and a connection structure 2, wherein the connection structure 2 is used for the second component 4 or the replacement component 5 to be installed on the first component 3, and the linkage limited rotation structure 1 is used to constrain the rotation range of the second component 4 before the replacement component 5 is successfully connected to the first component 3, thereby preventing the second component 4 from being separated from the first component 3 too early or easily.

[0074] In some embodiments, please combine Figure 5 , Figure 6 Referring to the figure, the connection structure 2 may include two through holes 21 for being provided on the first component 3, and an inserting portion 24 for being provided on the second component 4 or the replacement component 5, wherein the inserting portion 24 may extend into one of the two through holes 21 to achieve connection between the second component 4 and the first component 3. The connection structure 2 also includes a snap-fit ​​structure for rotating and snap-fitting the inserting portion 24 in the through hole 21; wherein the two through holes 21 are arranged at intervals.

[0075] It can be understood that the connecting structure 2 has a self-locking function, which can limit the second component 4 or the replacement component 5 to rotate to a preset angle relative to the first component 3 before it can be disassembled and assembled; with the cooperation of the connecting structure 2 and the linkage type rotation limiting structure 1, the second component 4 can only be rotated within the disassembly rotation range limited by the linkage type rotation limiting structure 1, and is maintained in connection with the first component 3 through the snap-fit ​​structure, so that the second component 4 cannot be removed from the first component 3 before the replacement component 5 is successfully connected to the first component 3.

[0076] Optionally, the buckle structure includes blocking portions 22 disposed on opposite sides of the through hole 21, and buckle portions 25 disposed on opposite sides of the insertion portion 24. The maximum length between the two blocking portions 22 is smaller than the maximum length between the two buckle portions 25, and the aperture of the through hole 21 is larger than the maximum length between the two buckle portions 25.

[0077] When in use, the snap portion 25 can be inserted into one of the through holes 21 from the circumferentially spaced position between the two blocking portions 22, and the snap portion 25 can be overlapped on the blocking portion 22 by rotating the insertion portion 24 to complete the assembly. At this time, the second component 4 or the replacement component 5 can be restricted from directly escaping from the through hole 21.

[0078] Preferably, if Figure 6 As shown, two limiting portions 23 corresponding to the two blocking portions 22 are provided on the inner side of the through hole 21. The two limiting portions 23 are longitudinally elongated, and their length directions are parallel to the axial direction of the through hole 21. They are used to limit the rotation direction of the second component 4 so that the second component 4 can only be rotated and disengaged in a single direction.

[0079] Optionally, in order to facilitate the replacement of the replacement part 5 and the second component 4, two blocking portions 22 in one through hole 21 are arranged on both sides of the width direction of the first component 3, and two blocking portions 22 in another through hole 21 are arranged on both sides of the length direction of the first component 3. Two buckle portions 25 can be arranged on both sides of the insertion portion 24 in the width direction of the second component 4.

[0080] In some embodiments, reference may be made to Figure 5 The linkage type rotation limiting structure 1 may include two rotation limiting structures 11 installed on the first component 3, and a limiting groove 12 provided on the second component 4 or the replacement component 5, and the first ends of the pry bars 111 of the two components are hinged to each other. Optionally, the two rotation limiting structures 11 are arranged in mirror symmetry; more preferably, the two rotation limiting structures 11 are located on the same straight line.

[0081] For the sake of convenience, the two rotation-limiting structures 11 are referred to as the first rotation-limiting structure 11a and the second rotation-limiting structure 11b. It is understandable that the first rotation-limiting structure 11a and the second rotation-limiting structure 11b are only used to distinguish the assembly sequence of the second component 4 and the replacement component 5, and do not limit two different structures for the corresponding assembly of the second component 4 and the replacement component 5. Similarly, the limiting groove 12 provided on the second component 4 is referred to as the first limiting groove 12a, and the limiting groove 12 provided on the replacement component 5 is referred to as the second limiting groove (not shown).

[0082] like Figure 5 As shown, the first rotation limiting structure 11a includes a first lever 111a, a first rotation axis 112a, and a first elastic member 113a; the first lever 111a, the first rotation axis 112a, and the first elastic member 113a can refer to the above description of the lever 111, the rotation axis 112, the elastic member 113, and the limiting groove 12, and will not be repeated here. Similarly, the second rotation limiting structure 11b includes a second lever 111b, a second rotation axis 112b, and a second elastic member 113b.

[0083] It can be understood that, in a natural state, the second ends of the first pry bar 111a and the second pry bar 111b extend to the side of the first component 3 facing the second component 4, and can be pushed back into the first component 3 under external force. At the same time, since the first pry bar 111a and the second pry bar 111b are hinged, when the second end of one of the pry bars 111a and the second pry bar 111b is pushed back, the second end of the other pry bar 111 of the first pry bar 111a and the second pry bar 111b can be linked and pushed back into the first component 3.

[0084] Secondly, in order to prevent the second component 4 from being disconnected first during the process of the replacement part 5 replacing the second component 4, the length of the second end of the pry bar 111 moving from the assembly completion position to the groove wall of the limiting groove 12 is less than the length of the required rotation path for the buckle portion 25 to disengage from the blocking portion 22, that is, before the second end of the pry bar 111 is lifted up, the insertion portion 24 cannot be disengaged from the through hole 21. It can be understood that the rotation path refers to the path of the buckle portion 25 rotating around the central axis of the through hole 21, which is a curve; the assembly completion position refers to the position where the second end of the pry bar 111 is located after the first component 3 and the second component 4 are assembled, generally located in the middle of the limiting groove 12; the length of the second end of the pry bar 111 moving from the assembly completion position to the groove wall of the limiting groove 12 is the limited disassembly rotation range between the first component 3 and the second component 4.

[0085] In some embodiments, Figure 5 As shown, the first component 3 is further provided with an escape opening 31 below the hinged position of the two pry bars 111 to facilitate the downward movement of the first end of the first pry bar 111 a and the first end of the second pry bar 111 b.

[0086] The following specifically describes the application process of the anti-break connection matching structure:

[0087] First, refer to Figure 5 , during the assembly process of the first component 3 and the second component 4, the first component 3 and the second component 4 are separated, the first pry bar 111a and the second pry bar 111b are in a natural state, and the second ends of each extend to the side of the first component 3 facing the second component 4;

[0088] Then, refer to Figure 7 , insert the insertion portion 24 provided on the second component 4 into one of the through holes 21 of the first component 3, the second component 4 abuts against the first component 3, and lifts up the second end of the first pry bar 111a, at which time the second end of the second pry bar 111b will also be linked and retracted into the first component 3; it can be understood that according to the position of the through hole 21 selected for insertion of the insertion portion 24, the second component 4 may also lift up the second end of the second pry bar 111b, which is not limited here;

[0089] Next, since the second ends of the first pry bar 111a and the second pry bar 111b are both retracted into the first component 3, the second component 4 can rotate without hindrance. As the second component 4 rotates, the second end of the first pry bar 111a is just located above the first limiting groove 12a on the second component 4, and under the action of the first elastic member 113a, the second end of the first pry bar 111a falls into the first limiting groove 12a (this process is not shown in the figure);

[0090] Then continue to rotate the second component 4, refer to Figure 8 The second component 4 pushes the second end of the second pry bar 111b back into the first component 3 and blocks the other through hole 21. The second end of the first pry bar 111a is retracted into the first component 3 under the action of the linkage until the second component 4 is completely fitted with the first component 3, and the buckle portion 25 provided on the second component 4 is completely overlapped on the blocking portion 22 of the first component 3, completing the assembly of the first component 3 and the second component 4. At this time, the first limiting groove 12a is located below the second end of the first pry bar 111a.

[0091] When the second component 4 needs to be replaced with the replacement part 5, refer to Fig. 9, rotate the second component 4 so that an angle is formed between the first component 3 and the second component 4. At this time, the other through hole 21 of the first component 3 leaks out, and the second end of the second pry bar 111b loses the obstruction of the second component 4 and re-extends under the action of the second elastic member 113b. The first pry bar 111a also falls into the first limiting groove 12a due to the linkage relationship, and the function of the first rotation limiting structure 11a takes effect; in other words, under the restriction of the first limiting groove 12a and the first pry bar 111a, the second component 4 can only rotate slightly (understandably, the angle of the slight rotation is the first preset angle, corresponding to the length of the arc groove; when the limiting portion 23 is not provided, the second component 4 can rotate in either clockwise or counterclockwise direction), and the rotation range is not enough to cause the buckle portion 25 of the second component 4 to disengage from the blocking portion 22, so during the replacement process, the second component 4 can remain connected to the first component 3, thereby preventing disconnection during the replacement process.

[0092] Then, refer to Fig.10 , the insertion portion 24 of the replacement part 5 can be inserted into the other through hole 21, and the replacement part 5 will push the second end of the second pry bar 111b back into the first component 3. Since the second pry bar 111b and the first pry bar 111a are linked, the second end of the first pry bar 111a will also be retracted into the first component 3; then, refer to Fig.11 , the replacement part 5 can continue to be rotated. Since the second end of the first pry bar 111a has been retracted, the replacement part 5 can push the second component 4 to continue to rotate during the rotation process, and finally the second component 4 can be successfully removed.

[0093] Finally, the replacement component 5 is rotated until it is completely fitted with the first component 3 . At this time, the second end of the second pry bar 111 b is located above the second limiting groove provided on the replacement component 5 .
