Description

Technical Field

[0001] This utility model relates to the field of compartment structures for accommodating replaceable components in equipment, and particularly to a single-operation, multi-lock compartment structure and an emergency start-up power supply. Background Technology

[0002] With differentiated development in various application scenarios, mobile electronic devices have evolved into different types. Different application scenarios present different requirements for mobile electronic devices. Replaceable components are a crucial requirement for mobile electronic devices. As the core power supply component of mobile electronic devices, the battery is a common replaceable component.

[0003] Typically, mobile electronic devices have a battery compartment on their casing. This compartment includes a housing with an opening and a cover to close the opening, facilitating battery replacement. For power supply, the compartment contains electrical connectors that connect the battery to the internal circuitry of the mobile electronic device. Thus, a fully charged battery module can replace a depleted one, and battery modules of different specifications can also be interchanged.

[0004] To protect the battery, the compartment structure is usually equipped with a locking mechanism. This mechanism locks the compartment cover in place at the compartment opening, thus securely locking the battery pack module inside the compartment structure. During use, pressing in the unlocking direction will unlock the compartment cover from the compartment opening, allowing for simple and convenient removal and installation of the battery pack module.

[0005] In existing technologies, the common locking mechanism for mobile electronic devices uses a latching structure on one side of the compartment cover and a locking structure on the other side. With this type of design, in the event of a drop, the locking structure may accidentally unlock due to vibration, or the latching structure may break and fail to lock, potentially causing the battery pack to detach from the compartment and become damaged, rendering the product unusable.

[0006] Chinese patent CN207082583U discloses a battery box and a mobile robot, specifically outlining its technical features: two handle positions, each corresponding to a first track. The handles can slide along the first track or detach from it. While this design features two latches, both ends must be operated simultaneously to unlock, making disassembly inconvenient. Furthermore, since the two latches are in the same direction, a collision in the same direction can easily cause them to disengage, leading to a failure of the protection mechanism.

[0007] Chinese patent CN107124906A discloses a battery holding component, a drone, and a charger, specifically revealing the following technical features: The battery holding component is designed to achieve single-handed battery securing and unlocking by utilizing an electrical interface and engaging parts in conjunction with an elastic element and an operating element. However, although this solution has multiple engaging parts, these parts are prone to simultaneous disengagement upon impact in the same direction, causing the locking protection to fail.

[0008] It is evident that existing technologies suffer from problems such as inconvenient operation, insecure locking of the compartment and its cover, and failure of the collision lock. Utility Model Content

[0009] To address the problems existing in the prior art, the main objective of this utility model is to provide a single-operation, multi-locking compartment structure and an emergency start-up power supply.

[0030] The operating part is disposed on the transmission slider and extends forward to the outside of the locking mechanism cavity. Transmission guide grooves are respectively provided on the left and right sides of the transmission slider. The rear ends of the two locking tongues are slidably placed in the two transmission guide grooves. The transmission guide grooves are inclined so as to pull the two locking tongues to slide in the left and right directions when the transmission slider slides in the front-back direction, so that the two locking tongues extend and retract into the compartment cover. The two elastic ends of the elastic element abut against the locking mechanism cavity and the transmission slider respectively, so as to cause the transmission slider to move forward and reset.

[0031] As a preferred embodiment of the above-mentioned compartment structure, the positioning mechanism includes:

[0032] The locking clip is located at the front end of the compartment cover.

[0033] The slot is located at the front end of the compartment opening;

[0034] The locking buckle and the locking slot cooperate with each other so that when the compartment cover is closed, the locking buckle is engaged in the locking slot; at least two sets of the locking buckle and the locking slot are provided.

[0035] In a second aspect, this utility model provides an emergency start-up power supply, which includes the single-operation multi-lock compartment structure of the above-mentioned technical solutions. The compartment body houses a battery pack module, and the compartment body is provided with a connector terminal, which is plugged into the connector terminal.

[0036] As a preferred embodiment of the above-mentioned emergency start-up power supply, the equipment housing includes an upper housing and a lower housing that cooperate with each other, and fastening covers disposed at both ends of the equipment housing; the fastening covers cover the sides of the equipment housing near the ends, the fastening covers abut against the outer surface of the compartment cover, the compartment body is disposed on the lower housing, the fastening covers are fastened to the upper housing by bolts in the horizontal direction, and the fastening covers are fastened to the lower housing by bolts in the vertical direction.

[0037] As a preferred embodiment of the above-mentioned emergency start-up power supply, the equipment housing includes an upper housing and a lower housing that cooperate with each other, and fastening covers disposed at both ends of the equipment housing; each of the fastening covers is provided with at least two legs on the side near the bottom of the lower housing, each of the legs has the same supporting plane and the supporting plane of each leg is higher than the housing cover.

[0038] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0039] (1) This utility model sets a locking mechanism at the front end of the compartment cover and the compartment opening cover, and sets at least two locking tongues on the left and right sides of the compartment cover and two locking holes on the left and right sides of the compartment opening through a locking mechanism. An operating part is set to drive the two locking tongues to extend into the locking holes and retract into the compartment cover at the same time, forming a triangular locking stress distribution structure. This allows the compartment and the compartment cover to be firmly locked under any vector impact force, which can provide effective protection for frequently replaced components (such as batteries) in mobile electronic devices. When replacing components, the operating part is operated to retract the locking holes on the left and right sides into the compartment cover, which serves as the replacement operation boundary.

[0040] (2) In this utility model, the first guide rail and the first slider cooperate to install the compartment cover in the compartment opening in a horizontal insertion manner. At the same time, the locking tongue and the locking hole lock the left and right sides. The cooperation of the first guide rail and the first slider strengthens the stability of the installation between the compartment cover and the compartment opening.

[0041] (3) In this utility model, by adding a second guide rail and a second slider, and combining the locking tongue and the lock hole to lock the left and right sides, the installation of the compartment cover and the compartment opening at the long side is more stable.

[0042] (4) In this utility model, further, by setting the protrusion, the cooperation between the lock tongue and the lock hole, the cooperation between the first slider and the first guide rail, and the cooperation between the second slider and the second guide rail are all located outside the preset compartment body, so that the internal space of the compartment body is comparable to or larger than the designed space.

[0043] (5) In this utility model, furthermore, through the locking mechanism, the operating part can only be pressed in the front-back direction, that is, the horizontal direction of the equipment housing, thereby avoiding the vertical force on the equipment housing and preventing the operating part from being accidentally triggered. The displacement of the transmission slider in the front-back direction drives the locking tongue to slide in the left-right direction through the transmission groove. The mutually perpendicular sliding directions further prevent the locking tongue from being accidentally locked. At the same time, when a single locking tongue is subjected to force, it is easy to cause the transmission slider to deflect, but it is difficult to cause the other locking tongue to displace. The elastic element is used for the reset of the transmission slider, making the operation more convenient, and also ensuring that the two locking tongues are always synchronously driven by the front-back direction of the transmission slider.

[0060] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. Furthermore, in the description of this disclosure, the terms "first," "second," etc., are used for descriptive purposes and to distinguish similar objects only, and there is no order between them, nor should they be construed as indicating or implying relative importance. Additionally, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0061] The devices disclosed herein include, as non-limiting examples, vehicle batteries, emergency jump starters, RC drones, RC racing cars, etc. The device housing 10 refers to the outer casing of these devices. Typically, the outer casing of these devices has a compartment body 11 and is equipped with a compartment cover 13 that closes the compartment opening 12, allowing for convenient replacement of non-limiting examples of battery pack modules 16, circuit modules, or functional modules, etc.

[0062] like Figures 1 to 9 The diagram shows a single-operation, multi-lock compartment structure according to an embodiment of the present invention. (Reference) Figure 1 and Figure 2 The compartment structure includes a compartment body 11 and a compartment cover 13. The compartment body 11 is mounted on the device housing 10. Exemplarily, a battery pack module 16 is housed within the compartment body 11. The compartment body 11 has a compartment opening 12 that extends outside the device housing 10, and the compartment cover 13 is fitted to and close onto the compartment opening 12. (Refer to...) Figure 3 and Figure 4 To achieve the purpose of this disclosure, the compartment structure also includes a locking mechanism and a latching mechanism. A locking mechanism is provided between the front end of the compartment cover 13 and the front end of the compartment opening 12. A latching mechanism is provided on the left side of the compartment cover 13 and the left side of the compartment opening 12, and on the right side of the compartment cover 13 and the right side of the compartment opening 12.

[0063] Specifically, refer to Figures 3 to 6 The locking mechanism includes a locking buckle 21 located at the front end of the compartment cover 13 and a locking groove 22 located at the front end of the compartment opening 12. The locking buckle 21 and the locking groove 22 cooperate with each other so that when the compartment cover 13 closes the compartment opening 12, the locking buckle 21 is engaged within the locking groove 22.

[0064] Specifically, refer to Figures 3 to 6 The locking mechanism includes two locking holes 32 respectively located on the left and right sides of the compartment opening 12, two locking tongues 31 respectively located on the left and right sides of the compartment cover 13, and an operating part 33. Each locking hole 32 can slide out and retract from the compartment cover 13 from its location side. The operating part 33 drives the two locking tongues 31, and under operation, the operating part 33 can drive the two locking tongues 31 to extend and retract synchronously from the compartment cover 13. The positions of the locking holes 32 and locking tongues 31 are mutually coordinated, so that when the compartment cover 13 closes the compartment opening 12, the locking holes 32 on the left and right sides can respectively accommodate the locking tongues 31 extending from the left and right sides of the compartment cover 13.

[0065] It is understandable that when the compartment cover 13 is closed onto the compartment opening 12, the front ends of the compartment cover 13 and the compartment opening 12 are fixed by the locking buckle 21 and the locking groove 22. The left side of the compartment cover 13 and the compartment opening 12 is fixed by the locking tongue 31 extending into the locking groove, and the right side of the compartment cover 13 and the compartment opening 12 is also fixed by the locking tongue 31 extending into the locking groove, forming a triangular locking stress distribution structure. Under the action of any vector impact force, even if one part is loosened due to the force, the other two parts remain tightly locked due to the angle difference and the smaller force, thereby preventing the compartment cover 13 from falling off the compartment opening 12. When it is necessary to replace the internal parts, press the operating part 33. The operating part 33 will drive the locking tongues 31 on the left and right sides to retract into the compartment cover 13. Then, operate the compartment cover 13 to move so that the locking buckle 21 disengages from the locking groove 22. Thus, the compartment cover 13 can be separated from the compartment body 11 with a simple operation to perform the corresponding battery pack module 16 replacement operation. After completion, close the compartment cover 13 back onto the compartment opening 12.

[0066] As can be seen, the compartment structure disclosed herein, through convenient operation and simple structure, achieves a secure lock between the compartment body and the compartment cover 13, and can provide effective protection for frequently replaced components (such as batteries) in mobile electronic devices.

[0067] Specifically, in this embodiment, refer to Figures 3 to 6 The compartment structure also includes a guide rail mechanism. The guide rail mechanism includes two first guide rails 41 and two first sliders 42. The two first guide rails 41 are respectively located on the left and right sides of the compartment opening 12 and near the rear side of the compartment opening 12, each extending in the front-back direction. The two first sliders 42 are respectively located on the left and right sides of the compartment cover 13 and near the rear side of the compartment opening 12, each extending in the front-back direction. Taking the right side as an example, the same applies to the left side. The first sliders 42 cooperate with the first guide rails 41, allowing the compartment cover 13 to be inserted horizontally into the rear end of the first guide rail 41 on the compartment opening 12 using its first sliders 42. When the first sliders 42 slide to the front end of the first guide rail 41, the compartment cover 13 closes the compartment opening 12, fixing the first sliders 42 within the first guide rails 41.

[0068] It is understandable that the cooperation between the first guide rail 41 and the first slider 42 allows the compartment cover 13 to be installed in the compartment opening 12 in a horizontal insertion manner. At the same time, the cooperation between the first guide rail 41 and the first slider 42 enhances the stability of the installation between the compartment cover 13 and the compartment opening 12.

[0069] Specifically, in this embodiment, refer to Figures 3 to 6 When the left and right sides of the rectangular compartment opening 12 are the long sides of the rectangular compartment, the guide rail mechanism also includes two second guide rails 43 and two second sliders 44. The two second guide rails 43 are respectively disposed on the left and right sides of the compartment opening 12. Each second guide rail 43 is located in front of the first guide rail 41 and extends in the same direction as the first guide rail 41. Correspondingly, the two second sliders 44 are also respectively disposed on the left and right sides of the compartment cover 13, each second slider 44 is located in front of the first slider 42 and extends in the same direction as the first slider 42. Notches are formed at the rear ends of the two second guide rails 43 to allow the second sliders 44 to be inserted into the second guide rails 43 through the notches. As the compartment cover 13 moves from the rear end to the front end, the second sliders 44 on the left and right sides of the compartment cover 13 also slide from the rear end of the second guide rails 43 to the front end, thus fixing the second sliders 44 within the second guide rails 43. It can be understood that the cooperation of the second guide rails 43 and the second sliders 44 further improves the connection stability between the compartment cover 13 and the compartment opening 12.

[0070] Specifically, in this embodiment, refer to Figures 3 to 6The left and right sides of the compartment opening 12 are respectively provided with protrusions 14 relative to the outer surface of the equipment housing 10. Two first guide rails 41 are respectively disposed on the protrusions 14 on the left and right sides, and two second guide rails 43 are respectively disposed on the protrusions 14 on the left and right sides. Two locking holes 32 are respectively disposed on the protrusions 14 on the left and right sides, and the two locking holes 32 are respectively located above the first guide rails 41 of the protrusions 14 on that side. It is worth noting that the front side of the end of the locking tongue 31 is configured as a bevel, while the rear side of the end of the locking tongue 31 is configured as a straight surface. Thus, when the compartment cover 13 is pushed forward, it can automatically retract into the compartment cover 13 when the bevel of the locking tongue 31 abuts against the protrusion 14. When the locking tongue 31 moves to the locking hole 32, it will automatically fall into the locking hole 32, and the rearward force of the compartment cover 13 under the abutment of the straight surface of the locking tongue 31 against the locking hole 32 will prevent the locking tongue 31 from being pushed back into the compartment cover 13. Thus, the protrusion 14 ensures that the engagement of the latch 31 and the lock hole 32, the engagement of the first slider 42 and the first guide rail 41, and the engagement of the second slider 44 and the second guide rail 43 are all located outside the preset compartment body 11, thereby making the internal space of the compartment body 11 comparable to or larger than the designed space.

[0071] Specifically, in this embodiment, refer to Figure 3 and Figure 4 When the hopper cover 13 is closed onto the hopper opening 12, the front section of the hopper cover 13 fits against the outer surface of the equipment housing 10, and the rear section of the hopper cover 13 fits against the upper surface of the protrusion 14. The first slider 42 and the second slider 44 are located on the left and right sides of the rear section of the hopper cover 13, and the locking mechanism is located on the rear section of the hopper cover 13. Thus, the hopper cover 13 can adapt to the shapes of the equipment housing 10 and the protrusion 14, forming a smooth process that makes the hopper cover 13 less susceptible to impact.

[0072] Specifically, in this embodiment, refer to Figures 7 to 9Overall, the locking mechanism includes two latches 31 on the compartment cover 13, an operating part 33, a transmission slider 36, and an elastic element 38. The compartment cover 13 has a locking mechanism cavity and a cover 39 that closes the locking mechanism cavity. The locking mechanism cavity has a first limiting groove 34 extending in the front-rear direction. The transmission slider 36 is disposed within the first limiting groove 34, so that it is constrained to slide only in the front-rear direction. The operating part 33 is integrally connected to the front end of the transmission slider 36 and extends outside the locking mechanism cavity. Second limiting grooves 35 are respectively provided on the left and right sides of the locking mechanism cavity. Each second limiting groove 35 extends in the left-right direction, and the two latches 31 are slidably disposed in the second limiting groove 35, so that they are constrained to slide only in the left-right direction. Transmission guide grooves 37 are respectively provided on the left and right sides of the transmission slider 36, and the two transmission guide grooves 37 are respectively inclined at approximately 45° to the sides. The rear ends of the two locking tongues 31 are slidably placed within the two transmission guide grooves 37, so that when the transmission slider 36 slides in the front-back direction, the two locking tongues 31 are pulled to slide in the left-right direction, so that the two locking tongues 31 extend and retract into the compartment cover 13. The elastic element 38 is configured as a helical spring, one elastic end of the helical spring abuts against the locking mechanism cavity, and the other end of the helical spring abuts against the rear end of the transmission slider 36, so that the transmission slider 36 moves forward to reset.

[0073] In use, the user can press the operating part 33, causing it to move backward. Simultaneously, the transmission slider 36 moves backward along the first limiting groove 34, compressing the helical spring. The two locking tongues 31 are then driven from the outside of the transmission guide groove 37 to the inside of the groove, moving inward in the left-right direction and retracting into the compartment cover 13. When the pressure on the operating part 33 is released, the helical spring extends, pushing the transmission slider 36 forward along the first limiting groove 34. The two locking tongues 31 are driven from the inside of the transmission guide groove 37 to the outside of the groove, extending beyond the compartment cover 13.

[0074] It is understood that the operating part 33 can only be pressed in the front-to-back direction, that is, the horizontal direction of the device housing 10, thereby avoiding the vertical force on the device housing 10 and preventing the operating part 33 from being accidentally triggered. The front-to-back displacement of the transmission slider 36 drives the locking tongue 31 to slide in the left-to-right direction through the transmission groove. The mutually perpendicular sliding directions further prevent the locking tongue 31 from being accidentally locked. At the same time, the force on a single locking tongue 31 can easily cause the transmission slider 36 to deflect, but due to the constraint of the mutually perpendicular transmission mode between the locking tongue 31 and the transmission slider 26, it is difficult to link the other locking tongue 31. The elastic element 38 is used for the reset of the transmission slider 36, making the operation more convenient, and also ensuring that the two locking tongues 31 are always synchronously driven by the transmission slider 36 in the front-to-back direction.

[0075] Specifically, in this embodiment, refer to Figure 3 and Figure 4There are three sets of locking buckles 21 and locking slots 22. Specifically, the front end of the compartment cover 13 has three horizontally arranged locking openings, and the inner side wall of the front end of the compartment opening 12 has three horizontally arranged locking slots 22. Each locking buckle 21 and locking slot 22 corresponds to and cooperates with each other. The arrangement of three sets of locking buckles 21 and locking slots 22 makes the connection between the compartment opening 12 and the compartment cover 13 at the front end more secure.

[0076] like Figure 10 The diagram shows an emergency start-up power supply according to an embodiment of the present invention. The emergency start-up power supply includes the compartment structure described in the above embodiment. The equipment housing 10 includes a cooperating upper housing 101 and a lower housing 102. The compartment structure is disposed in the lower housing 102. The compartment body 11 houses a battery pack module 16, and a connector terminal 15 is provided within the compartment body 11, to which the battery pack module 16 is connected.

[0077] Specifically, in this embodiment, fastening covers 103 are respectively provided at both ends of the upper housing 101 and the lower housing 102. Each fastening cover 103 covers the sides of the upper housing 101 near its end and the sides of the lower housing 102 near its end, thereby protecting the corners of the upper housing 101 and the lower housing 102 and making the connection between the upper housing 101 and the lower housing 102 more secure. The location of the compartment structure overlaps with that of the fastening cover 103, so that the fastening cover 103 abuts against the outer surface of the compartment cover 13. Thus, both sides of the compartment cover 13 are fixed between the locking groove 22 and the fastening cover 103, thereby making the fixation of the compartment cover 13 more secure. Furthermore, the bottom of the fastening cover 103 is fastened to the lower housing 102 by vertical bolts, and the top of the fastening cover 103 is fastened to the upper housing 101 by horizontal bolts. The fastening cover 103 has different fastening methods at the top and bottom, making it more resistant to impacts. The bottom of the fastening cover 103 uses a vertical fastening method, which can better press the upper surface of the compartment cover 13.

[0078] Specifically, in this embodiment, each fastening cover 103 is provided with at least two support legs 104 on one side near the bottom of the lower housing 102. Each support leg 104 has the same supporting plane, and the supporting plane of each support leg 104 is higher than the housing cover 13. The emergency start power supply is placed on the supporting plane by the four support legs 104. Even if the emergency start power supply falls, the point of fall is more likely to collide with each support leg 104, thereby protecting the housing cover 13.
