Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to an electronic equipment. Background Art

[0002] In the field of emergency communications, for backpack products that use an external battery and a host as a combined splicing structure, when the battery is replaced, the host will be powered off when the old battery is removed and the new battery has not yet been replaced, affecting the normal use and user experience of the product, and is not conducive to emergency on-site command and judgment.

[0003] The host of the related technology has a built-in backup power storage module. When the host battery alarm sounds, the built-in power storage module starts to discharge the host during the process of removing the old battery. After the new battery is installed, the built-in power storage module stops discharging.

[0004] The main disadvantages are as follows: the need to add a storage module, which increases the product size and weight; to achieve this function, the control circuit is relatively complex; when the host power consumption is large, the built-in storage module power consumption must also be large enough; the replacement process time of the old and new batteries is not controlled, and a long interval may cause the built-in storage module to lack energy and cannot guarantee that the new battery can still power the host before it is replaced.

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] Figures 1 to 3 An electronic device according to an embodiment of the utility model is shown, and the electronic device comprises a host module 1 and a battery module 2. The battery module 2 is detachably mounted on the host module 1, which provides great convenience for replacing the battery module 2, and the operation is simple and quick.

[0050] The host module 1 is provided with a groove 13 that can be connected to the battery module 2, and the groove 13 includes a first groove 131 and a second groove 132; the battery module 2 includes a battery connector 21 that can be inserted into the groove 13 to be electrically connected to the host module 1; after the battery connector 21 is inserted into any groove 13 of the host module 1, when the battery module 2 is rotated, the battery module 2 and the host module 1 remain electrically connected. When the battery connector 21 of the battery module 2 is inserted into the first groove 131 to be electrically connected to the host module 1, the battery module 2 is rotated to expose the second groove 132 of the host module 1, so that the battery connector 21 of the replacement battery module can be inserted into the second groove 132 to be electrically connected to the host module 1.

[0051] like Figure 2 and Figure 3As shown, in some embodiments, the host module 1 includes a host 11 and an interlocking linkage module 12, the interlocking linkage module 12 is assembled on the host module 1, and the battery module 2 is connected to the host module 1 through the interlocking linkage module 12 to supply power to the host module 1. The interlocking linkage module 12 includes a through hole for inserting a battery connector 21 of the battery module 2, and the through hole includes a first through hole 123 and a second through hole 124, and the first through hole 123 corresponds to the first groove 131, and the second through hole 124 corresponds to the second groove 132. The battery connector 21 of the battery module 2 is electrically connected to the host 11 through any through hole of the interlocking linkage module 12. The interlocking linkage module 12 includes a linkage component, and the linkage component has an extended state and a compressed state. In the extended state, the two ends of the linkage component are respectively in the first through hole 123 and the second through hole 124 after being extended; in the compressed state, the two ends of the linkage component are both retracted away from the through hole. It should be noted that there are two situations for setting the groove 13. The first situation is that the above-mentioned through hole is the groove 13, and the second situation is that the host module 1 has a part of the groove 13 structure set on the host 11 in addition to the above-mentioned through hole to form the groove 13 together.

[0052] The battery connector 21 includes a positioning groove that can cooperate with the linkage component. When the battery connector 21 of the battery module 2 is inserted into any through hole, the linkage component is in an extended state, and one end of the linkage component is in the positioning groove, the linkage component restricts the battery module 2 from being pulled out of the host module 1. When the battery connector 21 of the battery module 2 is inserted into any through hole and the linkage component is in a compressed state, the linkage component releases the restriction on the battery module 2.

[0053] Optionally, the number of linkage components is one, the positioning groove is in an arc shape, and a flange is provided on the positioning groove, and the cooperation with the linkage component is achieved by inserting at different angles; when the battery connector 21 of the battery module 2 is inserted into any through hole, the battery module 2 is rotated, and when the flange abuts against one end of the linkage component, the linkage component is in a compressed state, and the linkage component releases the restriction on the battery module 2. By rotating the battery module 2, the flange is separated from the abutment relationship with the linkage component, and the linkage component falls into the positioning groove again, and the linkage component restricts the battery module 2 from being pulled out of the host module 1.

[0054] Optionally, the number of linkage components is two, specifically including a first linkage component 121 and a second linkage component 122, and the two linkage components have the same composition and function and are independent of each other. The first linkage component 121 has two ends for limiting the battery module 2, and the second linkage component 122 has two ends for limiting the battery module 2. When the battery connector 21 of the battery module 2 is inserted into any of the through holes, and any of the linkage components is in an extended state, and one end of the linkage component is in the positioning groove, the linkage component limits the battery module 2 from being pulled out of the host module 1; when the battery connectors 21 of the two battery modules 2 are simultaneously inserted into the first through hole 123 and the second through hole 124, and the first linkage component 121 and the second linkage component 122 are both in a compressed state, the linkage component releases the restriction on the battery module 2.

[0055] The interlocking linkage module 12 has an extended state and a compressed state. Specifically, the first linkage component 121 is not affected by external forces in the extended state, and the two ends of the first linkage component 121 extend out of the first through hole 123 and the second through hole 124; the second linkage component 122 is also not affected by external forces in the extended state, and the two ends of the second linkage component 122 extend out of the first through hole 123 and the second through hole 124. Specifically, in the extended state, the two ends of the first linkage component 121 protrude from the inner wall surfaces of the first through hole 123 and the second through hole 124 to limit the battery module 2; the same is true for the second linkage component 122.

[0056] Combination Figure 4 The first linkage component 121 and the second linkage component 122 are in a compressed state at the same time. The first linkage component 121 is subjected to an external force, and its two ends are retracted into the first through hole 123 and the second through hole 124; the second linkage component 122 is subjected to an external force, and its two ends are retracted into the first through hole 123 and the second through hole 124, that is, its two ends do not protrude from the inner wall surfaces of the first through hole 123 and the second through hole 124, so that the movement of the battery module 2 will not be restricted, and the battery module 2 can be disassembled.

[0057] When the battery module needs to be replaced, the replacement battery module and the battery module 2 are both installed in the first through hole 123 and the second through hole 124. Under the external force of the battery module 2, the interlocking linkage module 12 unlocks the battery module 2 and the host module 1; when the battery module 2 is installed in the first through hole 123 or the second through hole 124, the battery module 2 and the host module 1 are locked.

[0058] When replacing the battery module 2, since there is a battery module 2 installed on one of the grooves 13 of the original host module 1, the replacement battery module is installed in the other groove 13, so that the replacement battery module and the battery module 2 are respectively installed in the two grooves 13 of the host module 1. At this time, the battery module 2 and the replacement battery module are in an unlocked state, and the battery module 2 can be taken out. When the battery module 2 is taken out, the replacement battery module will remain locked with the host module 1, and the reliability is high. The replacement battery module 2 must be inserted into the replacement battery module to unlock it, which can avoid the host module 1 from being powered off due to misoperation. Furthermore, the battery module 2 can also be fixed to the interlocking linkage module 12 by a buckle 22 to further lock the battery module 2.

[0059] Combination Figure 4 and Figure 5 In some embodiments, the interlocking linkage module 12 further includes a fixing seat 125, and the first through hole 123 and the second through hole 124 are respectively arranged at the two ends of the length direction of the fixing seat 125, and penetrate the fixing seat 125 in the axial direction. The first linkage assembly 121 and the second linkage assembly 122 are respectively installed on the opposite sides of the thickness direction of the fixing seat 125, and are located in the area between the first through hole 123 and the second through hole 124. An axial hole 1251 is provided in the middle of the fixing seat 125, and a limiting shaft 1252 is provided. The limiting shaft 1252 is penetrated in the axial hole 1251, and is used to connect with the first linkage assembly 121 and the second linkage assembly 122. Cover plates 1253 are respectively provided at both ends of the fixing seat 125, and are fixed to the cover plates 1253 by screws, and then installed on the host module 1 together.

[0060] Specifically, the first linkage assembly 121 includes a first sliding rod 1211, a second sliding rod 1212, a first elastic member 1213 and a first rotating plate 1214. The first elastic member 1213 is respectively sleeved outside the first sliding rod 1211 and the second sliding rod 1212. The first rotating plate 1214 is connected between the first sliding rod 1211 and the second sliding rod 1212 to achieve the linkage of the first sliding rod 1211 and the second sliding rod 1212. The first rotating plate 1214 and the second rotating plate 1224 are installed in the limiting shaft 1252 and can rotate along the circumferential direction of the limiting shaft 1252.

[0061] The second linkage assembly 122 includes a third sliding rod 1221, a fourth sliding rod 1222, a second elastic member 1223 and a second rotating plate 1224. The second elastic member 1223 is sleeved outside the third sliding rod 1221 and the fourth sliding rod 1222. The second rotating plate 1224 is connected between the third sliding rod 1221 and the fourth sliding rod 1222 to achieve the linkage of the third sliding rod 1221 and the fourth sliding rod 1222. The first elastic member 1213 and the second elastic member 1223 can be springs, which can be compressed under the action of external force, thereby driving the sliding rods to move inward synchronously. After the external force is removed, the sliding rods are reset to the extended state under the elastic force of the springs.

[0062] Taking the first linkage assembly 121 as an example, when any first sliding rod 1211 is subjected to force and moves, the first rotating plate 1214 transmits the force to synchronously drive the other first sliding rod 1211 to do the same movement, and the movement speed and distance of the two first sliding rods 1211 remain the same. Similarly, the second linkage assembly 122 is also the same, which will not be described in detail here.

[0063] like Figure 2 , Figures 6 to 10 As shown, the battery module 2 includes a battery connector 21. Fig.10 As shown, the battery connector 21 includes a positive electrode sheet 211 and a ring-shaped negative electrode sheet 212. The host module 1 is provided with an elastic connector 14 corresponding to the battery connector 21. The elastic connector 14 includes a positive electrode column 141 and a negative electrode column 142. The positive electrode column 141 is connected to the positive electrode sheet 211, and the negative electrode column 142 is connected to the negative electrode sheet 212. The elastic connector 14 is connected in parallel to the power supply line of the control board through a welding cable, and each elastic connector 14 can independently power the host module 1. The elastic connector 14 is a spring pin structure, and the elastic connector 14 also includes a connecting seat 143, and the connecting seat 143 can be fixed on the main board module by screws. A third elastic member is installed in the connecting seat 143, and the third elastic member can be a spring. The end connection of the positive electrode column 141 and the negative electrode column 142 is pushed out of the connecting seat 143 by the elastic force of the third elastic member. When it is subjected to external pressure, the front end connection of the positive electrode column 141 and the negative electrode column 142 is pressed into the connecting seat 143. The positive pole column 141 and the negative pole column 142 may be copper poles, and cables are welded to the tail ends of the positive and negative pole copper poles and connected to the power supply circuit of the control board.

[0064] The positive electrode sheet 211 and the annular negative electrode sheet 212 of the battery connector 21 are in contact with the positive and negative copper pillars of the elastic connector 14 on the host module 1 to achieve circuit connectivity. The elastic connector 14 on the host 11 and the annular negative electrode band on the battery can ensure that after the battery module 2 is rotated to any angle, it can still maintain a reliable circuit connection with the elastic connector 14 of the host module 1.

[0065] In some embodiments, the battery connector 21 further includes a housing 213, and the battery connector 21 further includes a housing 213, and the positioning grooves are provided on the housing 213, and the positioning grooves include a first positioning groove 2131 and a second positioning groove 2132. The housing 213 of the battery connector 21 is generally a convex step structure, and a circle of positioning grooves are respectively provided on the small end and the large end of the step, and each cooperates with the first linkage component 121 and the second linkage component 122. Specifically, it is defined here that the end with a smaller diameter of the step is provided with a first positioning groove 2131, and the end with a larger diameter of the step is provided with a second positioning groove 2132, so that the first positioning groove 2131 cooperates with the first sliding rod 1211 and the second sliding rod 1212 of the first linkage component 121, and the second positioning groove 2132 cooperates with the third sliding rod 1221 and the fourth sliding rod 1222 of the second linkage component 122. The step-shaped design ensures that when the battery module 2 is inserted, the first positioning groove 2131 will not be stuck by the third sliding rod 1221 or the fourth sliding rod 1222.

[0066] like Figure 6 , 8 As shown in Figures 9 and 10, by setting the two ends of the linkage assembly to different heights, the two ends of the linkage assembly located in the first through hole 123 and the second through hole 124 have different heights, so that the battery module 2 can be replaced in any hole. When the battery module 2 is installed in the first through hole 123 and the second through hole 124 is open, the second linkage assembly 122 is in an extended state, one end of the second linkage assembly 122 is in the second positioning groove 2132, and the other end of the second linkage assembly 122 is in the second through hole 124. Or when the battery module 2 is installed in the second through hole 124 and the first through hole 123 is open, the first linkage assembly 121 is in an extended state, one end of the first linkage assembly 121 is in the first positioning groove 2131, and the other end of the first linkage assembly 121 is in the first through hole 123.

[0067] When the battery module 2 is installed in the first through hole 123 and the replacement battery module is installed in the second through hole 124 , the first linkage assembly 121 and the second linkage assembly 122 are both in a compressed state.

[0068] like Figures 6 to 9As shown, optionally, both ends of the first linkage assembly 121 and both ends of the second linkage assembly 122 are provided with a locking portion 1215, and the locking portion 1215 limits the battery module 2 in one direction. The locking portion 1215 can be a D-shaped structure, with an arc surface on the insertion side and a right-angle surface on the extraction side, which includes a flat top surface and an arc bottom surface, the end surface of the flat top surface abuts against the inner wall surface of the first positioning groove 2131 or the second positioning groove 2132, and the arc bottom surface at least partially extends into the first positioning groove 2131 or the second positioning groove 2132. The D-shaped structure allows the battery connector 21 to be directly inserted into the first positioning groove 2131 or the second positioning groove 2132, but is restricted from being directly extracted, so the battery module 2 can be limited in one direction.

[0069] Combination Fig.11 In some embodiments, the interlocking linkage module 12 further includes a stopper 126. When the battery module 2 is connected to the host module 1, the stopper 126 is clamped in the first positioning groove 2131 and / or the second positioning groove 2132. Optionally, the stopper 126 and the first linkage assembly 121 are spaced around the first through hole 123, and the stopper 126 and the second linkage assembly 122 are spaced around the second through hole 124. Specifically, the stopper 126 can be a ball screw. After the battery module 2 is inserted into the first through hole 123 or the second through hole 124 of the host module 1, the positioning groove of the housing 213 of the battery connector 21 is limited by a sliding rod and three ball screws. The limiting steel ball of the ball screw can be compressed into the screw when under pressure to assist in positioning the battery. The three ball screws and the sliding rod are spaced around the battery connector 21 at an angle of 90° in space, so that the lateral elastic force of the battery module 2 during the plugging and unplugging process is more balanced, thereby improving reliability. Of course, they can also be distributed at other different angles, which is not limited here.

[0070] After the battery connector 21 is inserted into any input interface of the host module 1, the battery module 2 can rotate around the input interface without disconnecting the power supply between the battery module 2 and the host module 1, but it cannot be pulled out due to the restriction of the D-type limit structure. When the battery module 2 needs to be replaced, the replacement battery module must be inserted into another input interface of the host module 1, thereby driving the interlocking linkage module 12 to unlock the battery module 2 before the battery module 2 can be pulled out.

[0071] like Figure 6As shown, when the battery module 2 is installed in the first through hole 123 of the host 11, the replacement process is as follows: the first sliding rod 1211 is squeezed by the housing 213 of the battery connector 21 and is in a compressed state, driving the second sliding rod 1212 to be in a compressed state. The front end of the third sliding rod 1221 is limited in the second positioning groove 2132 of the housing 213 of the battery connector 21 of the battery module 2 to limit its withdrawal, and the fourth sliding rod 1222 is in an extended state. At this time, the power supply of the battery module 2 is to rotate the battery module 2, the battery connector 21 of the battery module 2 and the elastic connector 14 of the host module 1 will not be disconnected, and the battery module 2 continues to supply power to the host 11.

[0072] The internal action of the interlocking module is that the first sliding rod 1211 continues to be squeezed by the battery module 2 and is in a compressed state, driving the second sliding rod 1212 to be in a compressed state.

[0073] like Figure 8 As shown, as the replacement battery module is inserted, the positive and negative plates 212 of the battery connector 21 and the elastic connector 14 of the host 11 are first contacted and energized, and then the top of the fourth sliding rod 1222 is compressed by the shell 213 of the battery connector 21, gradually changing to a compressed state, driving the third sliding rod 1221 in a compressed state, and the battery module 2 is released from the limit and can be directly pulled out. Due to the auxiliary limit of the three ball screws, the battery module 2 and the replacement battery module can be prevented from accidentally falling off during replacement. At this time, the battery power supply situation is that the battery module 2 and the replacement battery module simultaneously power the host 11.

[0074] like Fig. 9 As shown, after the battery module 2 is pulled out, the first sliding rod 1211 is no longer subjected to external pressure and returns to the extended state. The second sliding rod 1212 is simultaneously restored to the extended state, and its front end extends into the first positioning groove 2131 of the battery connector 21 shell 213 of the replacement battery module, limiting the replacement battery module to prevent it from being pulled out. Because the fourth sliding rod 1222 is still squeezed by the battery connector 21 shell 213 of the replacement battery module, it is in a compressed state, driving the third sliding rod 1221 to be in a compressed state as well. At this time, the battery power supply situation is that the replacement battery module supplies power to the host 11.

[0075] Rotate the replacement battery module to a horizontal position to complete the battery replacement of battery module 2 and the replacement battery module.

[0076] It is understandable that this is a description of the replacement of the battery module 2 in one embodiment. When the battery module 2 is installed in the second through hole 124 of the host 11, the replacement process is similar to this process and will not be described in detail here.

[0077] The utility model can be applied in emergency communication scenarios, and can realize the host 11 without shutting down and replacing the battery without powering off, so as to avoid the host 11 from being powered off and terminating, and improve the stability and reliability of the emergency network. The interlocking linkage module 12 of the utility model can be automatically reset during the disassembly and assembly process, can be modularly installed, and has a simple overall structure. The battery replacement process is highly reliable, and the replacement battery module 2 must be inserted into the replacement battery module to unlock, which can effectively avoid the host module 1 from being powered off due to misoperation.

[0078] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should belong to the scope covered by the claims of the utility model.
