[0042] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field of the present invention. The words "including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.
[0043] In view of the problems existing in the prior art, the present invention provides a battery module for a drone, such as Figure 1 As shown, specifically:
[0044] The battery module for drone comprises a shell 1 with an opening on one side, and a blocking door 2 for blocking the opening of the shell 1. The shell 1 and the blocking door 2 are combined to form a sealed protective cover after the blocking door 2 completes the blocking of the opening of the shell 1, so that the battery body can be sealed in the protective cover, thereby protecting the battery body. Figure 1 In the example, the opening of the shell 1 is arranged on the right side surface. It should be understood that in other examples, the opening of the shell 1 is not limited to being arranged on the right side surface.
[0045] It is worth noting that when the housing 1 is fixed to the drone body, specifically, it can be fixed in the drone body by embedding. Figure 1 The space in which the blocking door 2 in the example can move left and right is exposed, and at the same time, the bottom of the shell 1 also needs to be exposed to the outside; it can also be suspended and fixed at the bottom of the drone body.
[0046] In one example, Figure 1As shown, a support plate 3 is fixedly arranged on one side of the blocking door 2 close to the housing 1, and the support plate 3 is arranged horizontally. Figure 1 In the example, the supporting plate 3 is arranged close to the upper part of the blocking door 2. Of course, in other examples, it is not limited to being arranged close to the upper part of the blocking door 2. The specific height setting can be adjusted according to the height of the battery body.
[0047] In this example, in order to provide a mounting position for the battery body, N battery storage compartments 4 for storing the battery body and isolated from each other are fixedly arranged on the lower end surface of the support plate 3, and the N battery storage compartments 4 and the support plate 3 are all arranged in the shell 1, wherein N is a positive integer greater than 1. In actual settings, the number of battery storage compartments 4 is at least 2, and this setting is to increase the voltage, so as to better provide power for the drone. In one example, as Figure 1 As shown, two adjacent battery storage compartments 4 are arranged close together, so that the space can be used more effectively and more battery bodies can be stored. Another advantage of this example is that the battery storage compartment 4 and the support plate 3 form an independent compartment body, so that the two adjacent battery bodies are isolated from each other, so that when one of the battery bodies fails or catches fire, it will not affect the adjacent battery bodies; at the same time, due to the setting of the isolation measures, the risk of disassembly and assembly can be effectively reduced, and more time can be gained for the disassembly and assembly process.
[0048] In one example, Figure 2 As shown, a fixed side plate assembly 5 matching the opening of the battery storage compartment 4 is provided on the inner side wall of the housing 1; Figure 2 In the example, the fixed side plate assembly 5 protrudes toward the horizontal center line of the inner cavity of the shell 1, so that when the battery body moves into the shell 1, it can provide a resistance force to the battery body, thereby fixing the battery body in the battery storage compartment 4 through the resistance effect.
[0049] In one example, the fixed side plate assembly 5 can be composed of two layers of material, one is a rigid material and the other is an elastic material, and the rigid material and the elastic material are fixedly connected, wherein the rigid material contacts the inner wall of the shell 1. The elastic material is arranged close to the battery body, so that it will not cause damage to the battery body when scratched, and at the same time, it can provide sufficient elastic reset force, so that the battery body can be fixed more firmly. It should be noted that the thickness ratio of the elastic material and the rigid material should be maintained at 1:9.
[0050] In one example, the lower end of the battery storage compartment 4 is slidably arranged with the inner bottom wall of the shell 1, and the upper end of the supporting plate 3 is slidably arranged with the inner top wall of the shell 1. This arrangement can ensure that the combined structure of the blocking door 2, the supporting plate 3 and the battery storage compartment 4 is always in a horizontal state, and can ensure that the combined structure always moves in a horizontal direction.
[0051] In one example, no locking limit device is provided at the left end of the support plate 3 and the battery storage compartment 4, so that in this example, the combined structure of the blocking door 2, the support plate 3 and the battery storage compartment 4 can be taken out from the shell 1; in another example, a locking limit device (not shown) is provided at the left end of the support plate 3 and / or the battery storage compartment 4, and the setting of the locking limit device can limit the combined structure of the blocking door 2, the support plate 3 and the battery storage compartment 4 from being taken out of the shell 1.
[0052] During operation, after the battery bodies are stored in the N battery storage compartments 4, a driving force is provided to the blocking door 2 in the horizontal direction (driving force is provided to the left, and the blocking door 2 moves to the left), so that the N battery bodies are sequentially moved to the left and installed into the housing 1 through the blocking door 2, the supporting plate 3 and the battery storage compartment 4, and the battery bodies are fixed in the battery storage compartment 4 through the resistance force of the fixed side plate assembly 5. Although in the present invention, the N battery bodies sequentially enter the housing 1 and are sequentially fixed in the battery storage compartment 4 through the fixed side plate assembly 5, the entry process of the N battery bodies can be completed at one time by only providing a driving force to the left, without adding other operation steps; at the same time, when the N battery bodies are sequentially fixed through the fixed side plate assembly 5, there is no need to add other fixing steps, and the fixing can be completed by providing a resistance force through the same fixed side plate assembly 5. It should be understood that the sequential fixing only has an order for entering the housing 1. For example, in one example, if the N battery bodies enter the housing 1 at the same time, they can be fixed at the same time through the fixed side plate assembly 5. Therefore, compared with the prior art, the present invention requires the battery body to be fixed in the shell by screws alone, which can achieve the effect of simultaneous installation and disassembly of N battery bodies without fixing or disassembling a single battery body, which can effectively improve the installation and disassembly efficiency.
[0053] In one embodiment, the battery storage compartment 4 is only provided with an opening at the front end. Figure 1 As shown, in order to cooperate with the opening, the fixed side panel assembly 5 is only provided on the front inner wall of the shell 1. When working, the battery body is placed from the opening into the battery storage compartment 4 (it should be noted that the battery body is pushed backwards until it cannot be pushed anymore. This is to provide a prerequisite for the next step of installation). As the battery storage compartment 4 moves to the left, the fixed side panel assembly 5 provides a driving force from front to back to fix the battery body in the battery storage compartment 4.
[0054] In the above embodiment, since the battery body is only subjected to force on one side, it is impossible to achieve the coincidence of the horizontal center line with the horizontal center line of the battery storage compartment 4. In this way, the assembled battery module will tilt because one side of the drone is heavy and the other side is light.
[0055] In order to solve the above problem, in one embodiment, the battery storage compartment 4 has two opposite openings (not shown) in a first direction (which can be understood as a front-to-back direction, the first direction and the horizontal direction are arranged perpendicular to each other), and two fixed side panel assemblies 5 matching the two openings of the battery storage compartment 4 are arranged on the inner side wall of the housing 1, such as Figure 2 As shown, the two fixed side panel assemblies 5 are arranged on both sides of the battery storage bin 4. In the process of the battery body entering the shell 1, the two fixed side panel assemblies 5 alternately resist the movement of the battery body in the first direction to adjust the horizontal center line of the battery body to coincide with the horizontal center line of the battery storage bin 4. The setting of this embodiment can adjust the position of the battery body so that the horizontal center line of the fixed battery body coincides with the horizontal center line of the battery storage bin 4. In this way, the assembled battery module will not cause an imbalance in the weight of the drone, and effectively prevent the drone from tilting.
[0056] Since the battery body is not fixed in the battery storage compartment 4, when placing the battery body, it is impossible to place the battery body in the same position, that is, the lengths of several battery bodies extending out of the battery storage compartment 4 are inconsistent, and there is a problem of unevenness. Therefore, the battery body extending out of the battery storage compartment 4 for a large distance will be misaligned with the fixed side plate assembly 5, causing the battery body to move to the left and get stuck. In order to solve the above problem, in one embodiment, as Figure 3 As shown, the fixed side plate assembly 5 is provided with a first anti-stuck groove 51 for traction at one end close to the blocking door 2. The groove cavity of the first anti-stuck groove 51 is a triangular structure, and the inclined surface is arranged from right to left. The arrangement of the inclined surface of the first anti-stuck groove 51 can play a role in guiding and preventing jamming, thereby preventing the battery body from being stuck when moving to the left.
[0057] When the battery body is driven to move to the left, an impact force will occur at the moment of contact with the fixed side plate assembly 5. The existence of the impact force will cause damage to both the battery body and the equipment.
[0058] In order to mitigate the impact force and protect the device and the battery body, in one embodiment, Figure 7 and Figure 8As shown, the fixed side panel assembly 5 includes a first side panel 52 and a second side panel 53, and a guide support assembly 54 disposed between the first side panel 52 and the second side panel 53 and used to connect the first side panel 52 and the second side panel 53. The first side panel 52 is movably disposed in the shell 1, and the second side panel 53 is statically disposed in the shell 1. Specifically, the state in which the second side panel 53 is statically disposed in the shell 1 can be formed by the second side panel 53 being directly fixed to the shell 1, or can be formed by the second side panel 53 being detachably disposed in the shell 1. The setting of the guide support assembly 54 in this embodiment is used to buffer the impact force. When implemented, the number of the guide support assemblies 54 can be set to 1, 2, 3 or more. In order to achieve a better buffering effect, the more the number of the guide support assemblies 54, the better, but it cannot be set too much to prevent the buffering force from being much greater than the impact force and failing to buffer the impact force. Preferably, the number of the guide support assemblies 54 is set to three, and the three guide support assemblies 54 are arranged at equal distances in the vertical direction.
[0059] It should be noted that the thickness of the first side plate 52 is smaller than the thickness of the second side plate 53 .
[0060] In one example, Figure 8 As shown, the guide support assembly 54 includes a guide support rod 541, a guide support cylinder 542 and a guide support spring 543. The guide support rod 541 is movably inserted in the guide support cylinder 542. The guide support spring 543 is wound outside the guide support rod 541, and the two ends of the guide support spring 543 are respectively fixedly connected to the side wall of the guide support rod 541 and the outer side wall of the guide support cylinder 542. The setting of the guide support assembly 54 can not only guide the movement of the first side plate 52, but also provide power for the reset movement of the first side plate 52.
[0061] In order to achieve a better fixing effect, in one embodiment, Figure 8 As shown, the battery module for the drone also includes a plurality of fastening mechanisms 8 arranged on the fixed side panel assembly 5, the fastening mechanism 8 includes a second movable groove 81 opened on the second side panel 53, a fastening plate 82 is movably arranged in the second movable groove 81, the side wall of the fastening plate 82 is fixedly connected with a connecting spring 83, the free end of the connecting spring 83 is fixedly connected to the side wall of the second movable groove 81, the fastening mechanism 8 also includes a contact plate 84 fixedly arranged on the first side panel 52, the free end of the contact plate 84 extends into the second movable groove 81, and a second anti-stuck groove 85 is opened on one end of the contact plate 84 located in the second movable groove 81.
[0062] The setting of the fastening mechanism 8 in this embodiment can assist the fixed side plate assembly 5 to play a role of resisting and fixing the battery body again, so that the battery body can be better fixed. During operation, when the first side plate 52 contacts the battery body, it can buffer the impact force, and after playing the buffering role, the first side plate 52 is reset to the initial position; after all battery bodies enter the shell 1, as the blocking door 2 continues to move, it will resist the first side plate 52 to move leftward, and the leftward movement of the first side plate 52 will bring the resisting plate 84 to move leftward, and the leftward movement of the resisting plate 84 will cause the inclined surface of the second anti-stuck groove 85 to resist the fastening plate 82 to move forward, so that the front end of the fastening plate 82 moves to the outside of the second movable groove 81, and all battery bodies are resisted at the same time.
[0063] The electrodes on the existing battery body are all arranged to protrude from the battery body. Therefore, in the aforementioned example, in order to enable the battery body to smoothly contact the second side plate 53, the thickness of the first side plate 52 is set to be smaller than the second side plate 53. In order to enable the second side plate 53 to both resist and fix the battery body and at the same time avoid the situation where the electrodes on the battery body are stuck, the fastening plate 82 in the aforementioned example initially retracts its front end into the second movable groove 81, so that the electrodes on the battery body can pass through the second movable groove 81 (specifically, there is no space for the fastening plate 82 in the second movable groove 81) to avoid getting stuck.
[0064] After achieving the above anti-stuck effect, in order to ensure the electrical connectivity of the circuit, in one embodiment, Fig. 9 , Fig.10 and Fig.11 As shown, the battery module for the drone also includes a circuit connection mechanism 10, which includes a wire plug 101, and a conductive rod 102 is connected to the male end of the wire plug 101, and the conductive rod 102 is arranged on the shell 1 and the second side plate 53, and the end of the conductive rod 102 located in the shell 1 is connected to a connecting wire 104, and the free end of the connecting wire 104 is fixedly connected to the electrode 103, and the electrode 103 is arranged on the fastening plate 82, wherein the electrode 103 is matched with the electrode on the battery body, and when the fastening plate 82 is in the zero position state, the electrode 103 retracts into the second movable groove 81.
[0065] The arrangement of the circuit connection mechanism 10 of this embodiment can ensure effective electrical connection of the circuit. When working, when the battery body is not fully inserted into the housing 1, the fastening plate 82 is hidden in the second moving groove 81. Fig.11As shown, at this time, the second side plate 53 and the electrode on the battery body will not contact each other; as the fastening plate 82 is resisted by the contact plate 84 and moves out of the second movable groove 81, the electrode 103 thereon will also move, thereby bringing the electrode 103 into contact with the electrode on the battery body to achieve circuit connectivity.
[0066] In the above embodiment, the fastening plate 82 will form a resistance to the battery body. In order to prevent the electrode 103 from being damaged by excessive squeezing and at the same time ensure that the electrode 103 is in effective contact with the electrode on the battery body, the left end of the electrode 103 is hidden in the fastening plate 82 (not shown) so that the electrode 103 can move outside the fastening plate 82 to contact the electrode on the battery body.
[0067] In one embodiment, Fig.11 As shown, the battery module for the drone also includes a displacement compensation mechanism 11, which includes a support spring 111 wound around the outside of the electrode 103, and the two ends of the support spring 111 are respectively fixedly connected to the side wall of the electrode 103 and the side wall of the fastening plate 82, and the electrode 103 is movably inserted into the fastening plate 82. The displacement compensation mechanism 11 also includes a first push-pull rod 112 with one end hinged to the electrode 103 and the other end hinged to the edge of the rotating disk 113. The rotating disk 113 is fixedly sleeved outside the second rotating rod 114, and the second rotating rod 114 is rotatably set in the second movable groove 81. The edge of the rotating disk 113 is also hinged with a second push-pull rod 115, and the free end of the second push-pull rod 115 is hinged to the fastening plate 82.
[0068] The arrangement of the displacement compensation mechanism 11 in this embodiment can compensate for the movement of the electrode 103. Specifically, while the electrode 103 is moved out of the second moving groove 81 by the fastening plate 82, the displacement compensation mechanism 11 makes the electrode 103 extend out of the fastening plate 82, thereby achieving contact with the electrode on the battery body. Fig.11 As shown, the fastening plate 82 moves to the left, and the second push-pull rod 115 will pull the rotating disk 113 to rotate clockwise. The clockwise rotation of the rotating disk 113 will push the electrode 103 to move relative to the fastening plate 82 through the first push-pull rod 112. In this way, in the example where the electrode 103 is hidden in the fastening plate 82, the left end of the electrode 103 can be pushed out of the fastening plate 82 to contact the electrode on the battery body.
[0069] In one embodiment, the two fixed side panel assemblies 5 are separately provided without any connecting structure provided therebetween.
[0070] In order to make the two fixed side plate assemblies 5 uniform and more operable, in another embodiment, as Figure 6and Figure 7 As shown, a plurality of reinforcing ribs 7 are arranged between the two fixed side panel assemblies 5, and the two fixed side panel assemblies 5 are fixedly connected by the plurality of reinforcing ribs 7, wherein the plurality of reinforcing ribs 7 are arranged near one end of the fixed side panel assembly 5 away from the blocking door 2, and the plurality of reinforcing ribs 7 are arranged on the same vertical line. Figure 6 In the example, the fixed side plate assembly 5 is an integral unit. Figure 7 In the example, the fixed side plate assembly 5 is a structure having the ability to buffer impact force as described above. Figure 6 still Figure 7 For example, the two fixed side panel assemblies 5 are connected as a whole through a plurality of the reinforcing ribs 7 .
[0071] The shells of existing battery modules are all open from the top and sealed on other sides. In this way, when the drone falls, the battery body cannot be separated from the drone and can only be damaged as the drone falls.
[0072] In order to solve the above problems, in one implementation, Fig.12 and Fig.13 As shown, sealing plates 12 are fixedly provided on the upper and lower ends of the two fixed side panel assemblies 5, and a release port (unnumbered) connected to the inner cavity is provided at the bottom of the shell 1. The two sealing plates 12 and the two fixed side panel assemblies 5 form a tube body, and the tube body is arranged to penetrate along the horizontal direction. The sealing plate 12 below is arranged in the release port and is used to seal the release port. The fixed side panel assembly 5 and the shell 1 are detachable, and the supporting plate 3 and the battery storage compartment 4 are movably arranged in the tube body.
[0073] The setting of the release port in this embodiment, as well as the detachable setting of the fixed side panel assembly 5 and the shell 1, can enable the battery body to detach from the shell 1 together with the tube body, so that it can be separated from the drone, thus preventing the battery body from falling along with the drone and being damaged.
[0074] In order to enable the battery body to be separated from the drone and to protect the separated battery body, in one embodiment, Fig.11 , Fig.12 , Fig.13 and Fig.14As shown, the battery module for drone also includes an electromagnetic drive mechanism 13, which includes an electromagnet 131 movably mounted on the outside of the conductive rod 102, the electromagnet 131 is embedded in the shell 1, and a magnet ring 132 matching the electromagnet 131 is fixedly mounted outside the conductive rod 102, and the electromagnetic drive mechanism 13 also includes an inductor 135 arranged on the outer surface of the shell 1, and a parachute 134 arranged on the upper end surface of the blocking plate 12 above, wherein the conductive rod 102 is movably plugged into the shell 1, and one end of the conductive rod 102 located in the shell 1 extends into the first through hole 133, and the first through hole 133 is opened on the second side plate 53. It should be noted that the inductor 135 is electrically connected to the external central processing unit.
[0075] The arrangement of the electromagnetic drive mechanism 13 in this embodiment can not only ensure the separation of the battery body from the drone when the drone fails and falls, but also ensure the smooth landing of the separated battery body. Specifically, when the sensor 135 collects the falling signal of the drone failure, the central processor will receive the falling signal. After processing, the central processor controls the electromagnet 131 to be energized to generate magnetism. Under the action of the magnetic force, it will generate an adsorption force on the magnet ring 132, and move the conductive rod 102 to the right through the magnet ring 132, and move to the outside of the first through hole 133. Since it is an instantaneous magnetic pulling force, it will break the connected connecting wire 104. At this time, the fixed side plate assembly 5 has no connection with the shell 1, and the combined structure of the fixed side plate assembly 5 and the blocking plate 12 will be separated from the drone from the release port under the action of gravity. When the separated battery body falls downward to a preset distance, the central processor will control the electric starting device on the parachute 134 to open the parachute 134, slow down the descending speed of the battery body, and make the battery body land smoothly on the ground.
[0076] In one embodiment, if Figure 1 , Figure 4 and Figure 5 As shown, the battery module for the drone also includes a first driving mechanism 6 for driving the blocking door 2 to move in the horizontal direction, the first driving mechanism 6 includes a first movable groove 61 opened on the inner top wall of the shell 1, a U-shaped support plate 62 is movably arranged in the first movable groove 61, the U-shaped support plate 62 is fixedly arranged on the side wall of the blocking door 2, a spur rack 63 is fixedly connected to one of the arms of the U-shaped support plate 62, the spur rack 63 is meshed with a driving gear 64, the driving gear 64 is fixedly sleeved outside the first rotating rod 65, the first rotating rod 65 is movably inserted into the top plate of the shell 1, and the upper end of the first rotating rod 65 is connected to the driving end of the driving motor 66, and the driving motor 66 is fixedly arranged on the outer top wall of the shell 1.
[0077] The first driving mechanism 6 in this embodiment is used to electrically drive the combined structure of the blocking door 2, the supporting plate 3 and the battery storage compartment 4 to move in the horizontal direction. When working, the driving motor 66 will drive the first rotating rod 65 to rotate, and the rotation of the first rotating rod 65 will drive the combined structure of the blocking door 2, the supporting plate 3 and the battery storage compartment 4 to move left and right in the horizontal direction through the driving gear 64, the spur rack 63 and the U-shaped support plate 62. At the same time, the mechanical connection between the driving motor 66, the driving gear 64 and the spur rack 63 can also provide a self-locking force to lock the position of the housing 1 and the blocking door 2.
[0078] In one embodiment, if Fig.15 and Fig.16 As shown, the battery module locking mechanism 14 for the drone includes a locking groove 141 provided on the supporting plate 3, and a second through hole 142 provided on the shell 1, a locking rod 143 matching the locking groove 141 is movably inserted in the second through hole 142, a reset spring 144 is wound around the outside of the locking rod 143, two ends of the reset spring 144 are respectively fixedly connected to the side walls of the locking rod 143 and the side walls of the second through hole 142, and a pull-out plate 145 is fixedly connected to the upper end of the locking rod 143.
[0079] In this embodiment, the driving force for the combined structure of the blocking door 2, the supporting plate 3 and the battery storage compartment 4 to move in the horizontal direction can be provided by human force. During the installation of the battery body, the combined structure is pushed to the left by human force, and when the locking rod 143 enters the locking groove 141, the combined structure is locked together with the housing 1, and the battery body is fixed in the housing 1.
[0080] Of course, in other examples, the locking of the blocking door 2 and the shell 1 is not limited to the use of the first driving mechanism 6 and the locking mechanism 14 in the above-mentioned embodiment. For example, it can also be locked by screws (not shown). Specifically, the blocking door 2 and the shell 1 are locked together by screws. Compared with the prior art, this locking method can greatly reduce the number of screws used. Only one or two screws are needed for fixing, which can also improve the installation and disassembly effects.
[0081] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention as described in the claims.
