Description

Technical Field

[0001] The present invention relates to the field of chamber structures for accommodating replaceable components in equipment, and in particular to a single-operation multi-locking chamber structure and an emergency starting power supply. Background Art

[0002] With the differentiated development of mobile electronic devices in different application scenarios, different types of mobile electronic devices have emerged. Different application scenarios require different mobile electronic devices. Replaceable components are a key requirement of mobile electronic devices. Batteries, as the core power supply component of mobile electronic devices, are a common replaceable component.

[0003] Typically, the housing of a mobile electronic device is equipped with a battery compartment structure. This compartment structure includes a housing with an opening and a cover for covering the opening, facilitating battery replacement. To provide power, the compartment structure is equipped with corresponding electrical connectors, allowing the batteries to be electrically connected to the internal circuitry of the mobile electronic device. This allows fully charged battery modules to replace low-charged ones, and battery modules of different specifications can also be interchanged.

[0004] To protect the batteries, the compartment structure is typically equipped with a locking mechanism that securely locks the compartment cover to the compartment opening, securing the battery module within the compartment structure. During use, pressing in the unlocking direction unlocks the compartment cover from the compartment opening, allowing the cover to be opened, making it easy and convenient to remove and install the battery module.

[0005] In the prior art, common locking mechanisms for mobile electronic devices employ a snap-on structure on one side of the compartment cover and a lock structure on the other. With this type of solution, if the device is dropped, the lock structure may accidentally unlock due to vibration, or the snap-on structure may break, causing the lock to fail. This can cause the battery pack to escape from the compartment, damaging it and rendering the product unusable.

[0006] Chinese patent publication number CN207082583U discloses a battery box and mobile robot, specifically disclosing technical features: two latches, one for each first track. The latches can slide along the first track and can also be separated from it. Although this solution has two latches, both ends must be operated simultaneously to unlock, making disassembly inconvenient. Furthermore, since the two latches are oriented in the same direction, a collision in the same direction can easily cause the latches to detach, rendering the protection system ineffective.

[0007] Chinese patent publication number CN107124906A discloses a battery retaining assembly, drone, and charger, specifically disclosing technical features: Through the design of the battery retaining assembly, an electrical interface and a latching portion, combined with the linkage of an elastic member and an operating member, enable single-handed securing and unlocking of the drone battery. However, despite the multiple latching portions provided in this solution, they can easily disengage simultaneously in the event of a simultaneous collision, rendering the locking protection ineffective.

[0008] It can be seen that the existing technology has problems such as inconvenient operation, loose locking of the bin body and the bin body cover, and failure of locking due to collision. Summary of the Invention

[0009] In order to solve the problems existing in the prior art, the main purpose of the present invention is to provide a single-operation multi-locking compartment structure and emergency starting power supply.

[0015] The above chamber structure is preferably such that the locking mechanism further comprises: a transmission slider and an elastic member; the chamber cover is provided with a locking mechanism cavity and a cavity cover for sealing the locking mechanism cavity; The locking mechanism cavity is provided with a first limiting groove, and the transmission slider is provided in the first limiting groove in a constrained sliding manner in the front-back direction; The left and right sides of the lock mechanism cavity are respectively provided with second limiting grooves, and the two locking tongues are respectively provided in the second limiting grooves in a constrained sliding manner along the left and right directions; The operating part is arranged on the transmission slider and extends forward outside the locking mechanism cavity. The left and right sides of the transmission slider are respectively provided with transmission guide grooves. The rear ends of the two lock tongues are respectively slidably placed in the two transmission guide grooves. The transmission guide grooves are arranged obliquely to pull the two lock tongues to slide in the left and right directions when the transmission slider slides in the front and rear directions, so that the two lock tongues extend and retract the warehouse cover; the two elastic ends of the elastic member are respectively in contact with the locking mechanism cavity and the transmission slider to enable the transmission slider to reset forward.

[0016] As a preferred embodiment of the above-mentioned chamber structure, the locking mechanism includes: The snap button is located at the front end of the compartment cover. A latching slot is provided at the front end of the compartment opening; The locking buckle and the locking groove cooperate with each other so that the locking buckle is locked in the locking groove when the bin cover closes the bin opening; at least two groups of the locking buckle and the locking groove are provided.

[0017] In a second aspect, the present invention provides an emergency starting power supply, which includes the single-operation multi-lock chamber structure of the above-mentioned technical solutions, wherein the chamber body accommodates a battery pack module, and a plug terminal is provided inside the chamber body, and the battery pack module is plugged into the plug terminal.

[0018] The above-mentioned emergency starting power supply is preferred, and the device housing includes an upper housing and a lower housing that cooperate with each other, and fastening covers arranged at both ends of the device housing; the fastening cover is wrapped around the various side surfaces of the device housing close to the end, the fastening cover abuts against the outer surface of the bin cover, the bin body is arranged in the lower housing, the fastening cover is fastened to the upper housing by horizontal bolts, and the fastening cover is fastened to the lower housing by vertical bolts.

[0019] The above-mentioned emergency starting power supply is preferred, and the device shell includes an upper shell and a lower shell that cooperate with each other, and fastening covers arranged at both ends of the device shell; each of the fastening covers is provided with at least two supporting feet on one side close to the bottom of the lower shell, and each of the supporting feet has the same supporting plane and the supporting plane of each of the supporting feet is higher than the bin cover.

[0020] Compared with the prior art, the present invention has the following beneficial effects: (1) The present invention provides a locking mechanism at the front end of the hopper cover and the hopper opening cover, and provides at least two lock tongues on the left and right sides of the hopper cover through a locking mechanism, and two lock holes on the left and right sides of the hopper opening, and provides an operating part to drive the two lock tongues to extend to the lock holes and retract into the hopper cover synchronously, thereby forming a triangular locking stress distribution structure, so that under the action of any vector impact force, the hopper body and the hopper cover can be firmly locked, which can provide effective protection for components that need to be frequently replaced (such as batteries) in mobile electronic devices. When replacing components, by operating the operating part, the lock holes on the left and right sides are retracted into the hopper cover, which serves as the replacement operation boundary.

[0021] (2) In the present invention, further, by cooperating with the first guide rail and the first slider, the bin cover is installed on the bin opening in a horizontal insertion manner. At the same time, combined with the locking of the left and right sides by the lock tongue and the lock hole, the cooperation of the first guide rail and the first slider enhances the installation stability between the bin cover and the bin opening.

[0022] (3) In the present invention, further, by cooperating with the additional second guide rail and the second slider, combined with the locking of the left and right sides by the lock tongue and the lock hole, the installation between the bin cover and the bin opening at the long side is further stabilized.

[0023] (4) In the present invention, further, by providing the protruding portion, 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 bin body, thereby making the internal space of the bin body equivalent to or larger than the designed space.

[0024] (5) In the present invention, further, through the setting of the locking mechanism, the operating part can only be pressed in the front-to-back direction, that is, in the horizontal direction of the device housing, thereby avoiding the vertical force on the device housing and avoiding the accidental triggering of the operating part. The displacement of the transmission slider in the front-to-back direction drives the lock tongue to slide in the left-to-right direction through the transmission slide groove. The mutually perpendicular sliding directions further prevent the lock tongue from being locked by mistake. At the same time, when a single lock tongue is subjected to force, it is easy to deflect the transmission slider, but it is difficult to cause the displacement of the other lock tongue. The elastic member is used to reset the transmission slider, making the operation more convenient, and at the same time, the two lock tongues are always driven synchronously in the front-to-back direction of the transmission slider.

The terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure. In addition, in the description of the present disclosure, the terms "first", "second", etc. are used only for descriptive purposes and to distinguish similar objects.

[0037] The devices disclosed herein include, as non-limiting examples, vehicle batteries, jump-start power supplies, RC drones, and RC racing cars. Device housing 10 refers to the outer shell of these devices. Typically, the outer shell of these devices includes a housing 11 and a housing cover 13 that closes a housing opening 12, allowing for convenient replacement of non-limiting examples of battery modules 16, circuit modules, or functional modules.

[0038] like Figures 1 to 9 As shown in FIG, a single-operation multi-locking chamber structure according to an embodiment of the present invention. Figure 1 and Figure 2 The chamber structure includes a chamber body 11 and a chamber cover 13. The chamber body 11 is provided on the device housing 10. For example, a battery module 16 is placed in the chamber body 11. The chamber body 11 has a chamber opening 12 that opens to the outside of the device housing 10, and the chamber cover 13 can be matched to cover the chamber opening 12. Figure 3 and Figure 4 To achieve the objectives of this disclosure, the chamber structure also includes a latching mechanism and a locking mechanism. A latching mechanism is provided between the front end of the chamber cover 13 and the front end of the chamber opening 12. Locking mechanisms are provided on the left side of the chamber cover 13 and the left side of the chamber opening 12, as well as on the right side of the chamber cover 13 and the right side of the chamber opening 12.

[0039] Specifically, refer to Figures 3 to 6 The locking mechanism includes a locking buckle 21 provided at the front end of the bin cover 13 and a locking groove 22 provided at the front end of the bin opening 12. The locking buckle 21 and the locking groove 22 cooperate with each other so that the locking buckle 21 is locked in the locking groove 22 when the bin cover 13 covers the bin opening 12.

[0040] Specifically, refer to Figures 3 to 6The locking mechanism includes two locking holes 32, one on each side of the hopper opening 12, two locking tongues 31, one on each side of the hopper cover 13, and an operating portion 33. Each locking hole 32 can slide out and retract from its location into the hopper cover 13. The operating portion 33 drives and connects the two locking tongues 31. When operated, the operating portion 33 can drive the two locking tongues 31 to synchronously extend and retract into the hopper cover 13. The positioning of the locking holes 32 and the locking tongues 31 cooperates with each other. When the hopper cover 13 covers the hopper opening 12, the left and right locking holes 32 can respectively accommodate the locking tongues 31 extending from the left and right sides of the hopper cover 13.

[0041] It can be understood that when the bin cover 13 is closed on the bin opening 12, the front ends of the bin cover 13 and the bin opening 12 are fixed by the locking buckle 21 and the locking groove 22, and the left sides of the bin cover 13 and the bin opening 12 are fixed by the locking tongue 31 extending into the locking groove, and the right sides of the bin cover 13 and the bin opening 12 are 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 of the places is loosened due to the force, the other two places remain locked due to the angle difference and the smaller force, thereby preventing the bin cover 13 from being separated from the bin opening 12. When the interior needs to be replaced, the operating part 33 can be pressed, and the operating part 33 can drive the locking tongues 31 on the left and right sides to retract into the warehouse cover 13, and then the warehouse cover 13 can be moved to disengage the locking buckle 21 from the locking groove 22, so that the warehouse cover 13 can be separated from the warehouse body 11 through simple operation, and the corresponding battery pack module 16 replacement operation can be carried out. After completion, the warehouse cover 13 can be re-covered on the warehouse opening 12.

[0042] It can be seen that the compartment structure disclosed herein achieves a firm lock between the compartment body and the compartment cover 13 through convenient operation and simple structure, and can provide effective protection for components (such as batteries) in mobile electronic devices that need to be frequently replaced.

[0043] Specifically, in this embodiment, Figures 3 to 6 , the chamber structure also includes a guide rail mechanism. The guide rail mechanism includes two first guide rails 41 and two first sliders 42. Among them, the two first guide rails 41 are respectively arranged on the left and right sides of the warehouse opening 12 and close to the rear side of the warehouse opening 12, and each first guide rail 41 extends in the front-to-back direction. The two first sliders 42 are respectively arranged on the left and right sides of the warehouse cover 13 and close to the rear side of the warehouse opening 12, and each first slider 42 extends in the front-to-back direction. Taking the right side as an example, the left side is similarly configured, the first slider 42 cooperates with the first guide rail 41 so that the warehouse cover 13 is inserted into the rear end of the first guide rail 41 on the warehouse opening 12 with its first slider 42 from the horizontal direction, and when the first slider 42 slides to the front end of the first guide rail 41, the warehouse cover 13 covers the warehouse opening 12, so that the first slider 42 is fixed in the first guide rail 41.

[0044] It can be understood that the cooperation between the first guide rail 41 and the first slider 42 enables the bin cover 13 to be installed in the bin 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 installation stability between the bin cover 13 and the bin opening 12.

[0045] Specifically, in this embodiment, Figures 3 to 6 When the left and right sides of the rectangular bin opening 12 are the long sides of the rectangular bin, the guide rail mechanism further 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 bin 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, two second sliders 44 are also respectively disposed on the left and right sides of the bin cover 13, each second slider 44 being located in front of the first slider 42 and extending in the same direction as the first slider 42. The rear ends of the two second guide rails 43 each have a notch, allowing the second slider 44 to fit into the second guide rail 43 through the notch. As the bin cover 13 moves from the rear end to the front end, the second sliders 44 on the left and right sides of the bin cover 13 also slide from the rear end to the front end of the second guide rail 43, securing the second sliders 44 within the second guide rail 43. It can be understood that the coordination between the second guide rails 43 and the second sliders 44 further enhances the stability of the connection between the bin cover 13 and the bin opening 12.

[0046] Specifically, in this embodiment, Figures 3 to 6 The left and right sides of the housing opening 12 are respectively provided with protrusions 14 relative to the outer surface of the device 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 correspondingly 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 an inclined surface, while the rear side of the end of the locking tongue 31 is configured as a straight surface. Therefore, when the housing cover 13 is pushed forward, the locking tongue 31 automatically retracts into the housing cover 13 when the inclined surface abuts the protrusion 14. When the locking tongue 31 moves to the locking hole 32, it automatically falls into the locking hole 32. Under the abutment between the straight surface of the locking tongue 31 and the locking hole 32, the backward force applied to the housing cover 13 cannot push the locking tongue 31 back into the housing cover 13. Therefore, the setting of the protrusion 14 makes the cooperation between the lock tongue 31 and the lock hole 32, the cooperation between the first slider 42 and the first guide rail 41, and the cooperation between the second slider 44 and the second guide rail 43 all located outside the preset warehouse body 11, so that the internal space of the warehouse body 11 is equivalent to or larger than the designed space.

[0047] Specifically, in this embodiment, Figure 3 and Figure 4When the hopper cover 13 is closed over the hopper opening 12, the front section of the hopper cover 13 fits on the outer surface of the device housing 10, and the rear section of the hopper cover 13 fits on the upper surface of the protrusion 14. The first and second sliders 42 and 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 shape of the device housing 10 and the protrusion 14, forming a smooth sliding process, making the hopper cover 13 less susceptible to collisions.

[0048] Specifically, in this embodiment, Figures 7 to 9 Generally speaking, the locking mechanism includes two locking tongues 31 provided on the hopper cover 13, an operating portion 33, a transmission slider 36, and an elastic member 38. The hopper cover 13 is provided with a locking mechanism cavity and a cavity cover 39 that closes the locking mechanism cavity. The locking mechanism cavity is provided with a first limiting groove 34 extending in the front-to-back direction. The transmission slider 36 is provided within the first limiting groove 34 so as to be constrained to slide only in the front-to-back direction. The operating portion 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 provided on the left and right sides of the locking mechanism cavity. Each second limiting groove 35 extends in the left-to-right direction, and the two locking tongues 31 are slidably provided in the second limiting groove 35 so as to be constrained to slide only in the left-to-right direction. Transmission guide grooves 37 are 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 degrees to the sides. The rear ends of the two locking tongues 31 are slidably disposed within the two transmission guide slots 37, respectively. As the transmission slider 36 slides forward and backward, the two locking tongues 31 are pulled to slide left and right, thereby extending and retracting the two locking tongues 31 into the compartment cover 13. The elastic member 38 is configured as a coil spring, one end of which abuts the latch mechanism cavity, and the other end of which abuts the rear end of the transmission slider 36, thereby causing the transmission slider 36 to return forward.

[0049] During use, the user presses the operating portion 33, causing the operating portion 33 to move backward. The transmission slider 36 then simultaneously moves backward along the first limiting groove 34, compressing the coil spring and driving the two locking tongues 31 from the outside of the transmission guide groove 37 to the inside of the transmission guide groove 37, thereby moving inward in the left-right direction and retracting into the interior of the bin cover 13. When the pressing of the operating portion 33 is released, the coil spring extends, pushing the transmission slider 36 forward along the first limiting groove 34, and driving the two locking tongues 31 from the inside of the transmission guide groove 37 to the outside of the transmission guide groove 37 and extending out of the bin cover 13.

[0050] It can be understood that the operating portion 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 avoiding the accidental triggering of the operating portion 33. The front-to-back displacement of the transmission slider 36 drives the lock tongue 31 to slide in the left-to-right direction through the transmission slide groove. The mutually perpendicular sliding directions further prevent the lock tongue 31 from being accidentally locked. At the same time, the force applied to a single lock tongue 31 can easily cause the transmission slider 36 to deflect, but due to the constraint of the mutually perpendicular transmission mode between the lock tongue 31 and the transmission slider 26, it is difficult to link the other lock tongue 31. The elastic member 38 is used to reset the transmission slider 36, making the operation more convenient, and at the same time, it also ensures that the two lock tongues 31 are always synchronously driven in the front-to-back direction by the transmission slider 36.

[0051] Specifically, in this embodiment, Figure 3 and Figure 4 There are three sets of latches 21 and slots 22. Specifically, the front end of the hopper cover 13 is provided with three horizontally arranged latching openings, and the front inner wall of the hopper opening 12 is provided with three horizontally arranged latching slots 22. Each latch 21 and each latching slot 22 correspond to each other. The provision of three sets of latches 21 and slots 22 ensures a more secure connection between the hopper opening 12 and the hopper cover 13 at the front end.

[0052] like Figure 10 The figure shows an emergency starting power supply according to an embodiment of the present invention. This emergency starting power supply includes the compartment structure described in the above embodiment. The device housing 10 comprises an upper housing 101 and a lower housing 102 that cooperate with each other. The compartment structure is disposed within the lower housing 102. The compartment body 11 houses a battery module 16, which is provided with connector terminals 15 within the compartment body 11. The battery module 16 is pluggably connected to the connector terminals 15.

[0053] Specifically, in this embodiment, a fastening cover 103 is provided at each end of the upper shell 101 and the lower shell 102. Each fastening cover 103 wraps around each side surface of the upper shell 101 near the end, and wraps around each side surface of the lower shell 102 near the end, thereby protecting each corner of the upper shell 101 and the lower shell 102, making the connection between the upper shell 101 and the lower shell 102 more secure. The chamber structure overlaps with the setting position of the fastening cover 103, so that the fastening cover 103 abuts the outer surface of the hopper cover 13. As a result, the two sides of the hopper cover 13 are respectively fixed between the locking groove 22 and the fastening cover 103, thereby making the fixation of the hopper cover 13 more secure. Furthermore, the bottom of the fastening cover 103 is fastened to the lower shell 102 by vertical bolts, and the top of the fastening cover 103 is fastened to the upper shell 101 by horizontal bolts. The top and bottom of the fastening cover 103 are fixed in different ways, making the fastening cover 103 more adaptable to collisions. The bottom of the fastening cover 103 adopts a vertical fastening method, which can better press the upper surface of the compartment cover 13.

[0054] Specifically, in this embodiment, each fastening cover 103 is provided with at least two legs 104 on one side near the bottom of the lower housing 102. Each leg 104 has a common support plane and its support plane is higher than that of the compartment cover 13. The emergency starting power supply is supported on the support plane by the four legs 104. Even if the emergency starting power supply falls, the falling point is more likely to collide with the legs 104 first, thereby protecting the compartment cover 13.

[0055] The above embodiments primarily illustrate the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
