Description

Technical Field

[0001] This invention belongs to the field of drone battery technology, and in particular relates to a mounting structure for drone batteries. Background Technology

[0002] Given the stringent requirements of unmanned aerial vehicle (UAV) systems for continuous power supply to their onboard avionics, their batteries not only need sufficient energy output capacity but also require meticulous structural design that considers both installation and fixation. Specifically, the battery cells must be able to be quickly and easily removed and replaced by operators to accommodate frequent maintenance or mission changes. Simultaneously, they must provide extremely robust and stable restraint in complex flight environments and maneuvers, such as when encountering airflow disturbances or acceleration / deceleration impacts, effectively preventing any power outages or flight safety hazards that could result from battery displacement, loosening, or even accidental detachment. Therefore, modern UAV battery fixing solutions require significant optimization and upgrades compared to traditional strapping methods.

[0003] In the current design, the method of connecting the battery by freely swinging the wires is not only complicated to operate, requiring effort to align the pins and straighten the wire harness, which greatly reduces the convenience of disassembly and assembly; at the same time, this kind of exposed cable connection is very prone to loosening or poor contact under the vibration and impact of flight, and the physical reliability of the connection is difficult to guarantee.

[0004] Due to the inherent operational inconvenience and connection fragility of the wire-spinning connection in the relevant technology, as well as the lack of effective compensation design for battery deformation in the fixing structure when dealing with temperature changes, the contact pressure at the connector interface is unstable or even fails, resulting in serious power supply reliability and safety issues. Summary of the Invention

[0005] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A mounting structure for a drone battery includes a front limiting mechanism, a middle limiting mechanism, and a rear limiting mechanism;

[0008] The front limiting mechanism, the middle limiting mechanism and the rear limiting mechanism are all arranged on the end face of the cabin frame. The front limiting mechanism, the middle limiting mechanism and the rear limiting mechanism are axially distributed along the battery installation direction and respectively abut against the front end face, the outer surface of the middle section and the rear end face of the battery body to jointly constrain the position of the battery on the end face of the cabin frame.

[0009] The front limiting mechanism includes a front limiting seat fixedly installed on the end face of the bulkhead inside the cabin and two elastic buckle assemblies symmetrically arranged on the front limiting seat;

[0010] The front end of the battery is provided with a limiting structure corresponding to the front limiting seat; the elastic buckle assembly is configured to lock when the limiting structure of the battery abuts against the front limiting seat to constrain the axial displacement of the battery, and to disassemble by manual release.

[0011] Furthermore, the intermediate limiting mechanism includes an intermediate limiting seat fixedly installed on the end face of the internal frame of the cabin and two intermediate limiting ears fixedly installed in the middle of the battery body.

[0012] The intermediate limiting seat is provided with intermediate limiting grooves on its opposite sides;

[0013] The intermediate limiting ear can slide horizontally into and engage with the corresponding intermediate limiting groove;

[0014] The intermediate limiting groove can accommodate the intermediate limiting ear and restrict its displacement in the vertical direction.

[0015] Furthermore, the rear limiting mechanism includes a rear limiting base fixedly installed on the end face of the internal bulkhead of the cabin, two rear limiting ears fixedly installed at the rear of the battery body, and two locking mechanisms installed on the rear limiting base.

[0016] The rear limiting base is provided with rear limiting grooves on its opposite sides;

[0017] The rear limiting ear can be inserted into the corresponding rear limiting groove to achieve horizontal positioning;

[0018] The locking mechanism is used to limit the rear of the battery.

[0019] Furthermore, the locking mechanism includes a buckle base, a rear limiting buckle, and a glass bead set screw. The buckle base and the rear limiting base are integrally connected at their ends. One end of the rear limiting buckle is rotatably engaged with the buckle base via a knurled pin, and the other end of the rear limiting buckle is detachably connected to the buckle base via the glass bead set screw. The rear limiting buckle is used to limit the rear of the battery.

[0020] Furthermore, the limiting structure includes a limiting slot and a front limiting ear that can cooperate with the limiting slot. The front limiting ear is located at the front end of the power supply, and the limiting slot is located at the front limiting seat. The shape of the limiting slot is adapted to the front limiting ear.

[0021] The front limiting ear can be inserted into the limiting slot to achieve the initial positioning of the battery body relative to the front limiting seat;

[0022] When the front limiting ear is inserted into the limiting slot, the elastic buckle assembly locks in to constrain the axial displacement of the front limiting ear within the limiting slot.

[0023] Furthermore, the elastic buckle assembly includes a buckle body, a travel hole, a return spring, and a limiting screw. The end of the front limiting seat is provided with a front limiting groove, the top of the buckle body is provided with a pressing part, the side of the buckle body is provided with a buckle limiting ear, and the travel hole is vertically disposed in the middle of the buckle body.

[0024] The lower part of the buckle body is accommodated in the front limiting groove;

[0025] The reset spring is disposed at the bottom of the front limiting groove and elastically abuts against the bottom of the limiting groove and the buckle body;

[0026] The limiting screw passes through the travel hole and is threadedly connected to the front limiting seat. Its head size is larger than the width of the travel hole, thereby slidably constraining the buckle body on the front limiting seat and allowing the buckle body to move vertically along the limiting groove within a limited travel.

[0027] When the buckle body is in an unpressed state, its position blocks the front limit ear that is inserted into the upper limit slot of the front limit seat, thereby limiting its axial displacement.

[0028] By pressing the pressing part, the buckle body is driven to overcome the spring force of the reset spring and move downward, so that the buckle limiting ear can be disengaged from the obstruction of the front limiting ear, thereby achieving unlocking.

[0029] Furthermore, the front limit seat is provided with a baffle in the middle, the baffle is provided with a slot that can cooperate with the power socket, one side of the slot is directly opposite the power socket, and the other side of the slot is provided with a socket protective cover.

[0030] Furthermore, the buckle body is provided with a visual identification area, which is exposed outside the front limit seat when it is in the initial locked position under the action of the return spring;

[0031] When the visual marking area is pressed down to the unlocked position against the force of the reset spring, the visual marking area is blocked by the front limit seat;

[0032] The exposed and obscured states of the visual identification area correspond to the locked and unlocked states of the elastic buckle component, respectively.

[0033] Compared with existing technologies, the mounting structure for drone batteries described in this invention has the following advantages:

[0034] 1. The front limiting mechanism achieves initial positioning by precisely fitting and inserting the limiting ear at the front end of the battery into the limiting slot. Combined with the elastic buckle components distributed symmetrically on both sides, it automatically locks in place the moment the battery comes into contact, forming a rigid constraint on the axial displacement of the battery, effectively ensuring the contact reliability of the battery connector in the vibration environment of flight.

[0035] 2. The intermediate limiting mechanism provides full-range load-bearing support for the battery body by guiding the limiting ear in the middle of the battery to slide horizontally into the limiting groove, which greatly reduces the risk of deformation of the battery shell due to bending stress during flight maneuvers.

[0036] 3. After the rear limiting ear is inserted into the rear limiting groove to achieve precise horizontal positioning of the rear of the battery, the rotary locking mechanism applies continuous clamping force through the ratchet locking effect of the glass ball set screw, forming a three-way limiting (axial anti-dislodgement, lateral anti-torsion, and vertical anti-vibration).

[0037] 4. The three mechanisms are distributed along the battery installation axis, and targeted constraints are implemented for the front, middle and rear sections of the battery respectively: the front section is used to ensure electrical interface and automatic locking, the middle section is used to ensure support stiffness and deformation compensation, and the rear section is used to achieve manual locking redundancy.

[0049] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0052] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] A mounting structure for drone batteries, such as Figure 1 As shown, it includes a front limiting mechanism 2, a middle limiting mechanism 3, and a rear limiting mechanism 4; the front limiting mechanism 2, the middle limiting mechanism 3, and the rear limiting mechanism 4 are all arranged on the end face 1 of the cabin frame. The front limiting mechanism 2, the middle limiting mechanism 3, and the rear limiting mechanism 4 are axially distributed along the battery installation direction and respectively abut against the front end face, the outer surface of the middle section, and the rear end face of the battery body to coordinately constrain the position of the battery on the end face 1 of the cabin frame.

[0054] The front limiting mechanism 2 includes a front limiting seat 201 fixedly installed on the end face 1 of the cabin bulkhead and two elastic latching assemblies symmetrically arranged on the front limiting seat 201. The front end of the battery has a limiting structure corresponding to the front limiting seat 201. The elastic latching assemblies are configured to lock when the limiting structure of the battery abuts against the front limiting seat 201 to constrain the axial displacement of the battery, and can be disassembled by manual release. The front limiting mechanism 2 achieves initial positioning through the precise fitting and insertion of the limiting ear at the front end of the battery into the limiting slot. Combined with the symmetrically distributed elastic latching assemblies on both sides, they automatically lock at the moment of battery contact, forming a rigid constraint on the axial displacement of the battery, effectively ensuring the contact reliability of the battery connector in flight vibration environment.

[0055] The intermediate limiting mechanism 3 includes an intermediate limiting seat fixedly installed on the end face 1 of the internal frame of the cabin and two intermediate limiting ears 502 fixedly installed in the middle of the battery body. The intermediate limiting seat has intermediate limiting grooves 301 on its opposite sides. The intermediate limiting ears 502 can slide horizontally into and engage with the corresponding intermediate limiting grooves 301. The intermediate limiting grooves 301 can accommodate the intermediate limiting ears 502 and limit their displacement in the vertical direction. The intermediate limiting mechanism 3 provides full-range load-bearing support for the battery body through the guiding engagement method of the limiting ears in the middle of the battery sliding horizontally into the limiting grooves, which greatly reduces the risk of deformation of the battery casing due to bending stress during flight maneuvers.

[0056] The rear limiting mechanism 4 includes a rear limiting base 401 fixedly installed on the end face 1 of the internal frame of the cabin, two rear limiting ears 503 fixedly installed at the rear of the battery body, and two locking mechanisms installed on the rear limiting base 401. The rear limiting base 401 has rear limiting grooves 4011 on its opposite sides. The rear limiting ears 503 can be inserted into the corresponding rear limiting grooves 4011 to achieve horizontal positioning. The locking mechanisms are used to limit the rear of the battery. After the rear limiting ears 503 are inserted into the rear limiting grooves 4011 to achieve precise horizontal positioning of the rear of the battery, the rotary locking mechanism applies a continuous clamping force through the ratchet locking effect of the glass ball set screw 404 to form a three-way limiting (axial anti-dislodgement, lateral anti-torsion, and vertical anti-vibration).

[0057] The locking mechanism includes a buckle base, a rear limit buckle 402, and a glass bead set screw 404. The buckle base and the rear limit base 401 are integrally connected at their ends. One end of the rear limit buckle 402 is rotatably engaged with the buckle base through a knurled pin 403, and the other end of the rear limit buckle 402 is detachably connected to the buckle base through a glass bead set screw 404. The rear limit buckle 402 is used to limit the rear of the battery.

[0058] The limiting structure includes a limiting slot and a front limiting ear 501 that can cooperate with the limiting slot. The front limiting ear 501 is located at the front end of the power supply 5, and the limiting slot is located on the front limiting seat 201. The shape of the limiting slot is adapted to the front limiting ear 501. The front limiting ear 501 can be inserted into the limiting slot to achieve the initial positioning of the battery body relative to the front limiting seat 201. When the front limiting ear 501 is inserted into the limiting slot, the elastic buckle assembly locks to constrain the axial displacement of the front limiting ear 501 in the limiting slot.

[0059] The elastic buckle assembly includes a buckle body 203, a travel hole 2032, a return spring 204, and a limiting screw 202. The end of the front limiting seat 201 is provided with a front limiting groove 2011. The top of the buckle body 203 is provided with a pressing part, and the side of the buckle body 203 is provided with a buckle limiting ear. The travel hole 2032 is vertically through the middle of the buckle body 203. The lower part of the buckle body 203 is accommodated within the front limiting groove 2011. The return spring 204 is located at the bottom of the front limiting groove 2011 and elastically abuts against... The limiting screw 202 is connected between the bottom of the limiting groove and the buckle body 203; the limiting screw 202 passes through the stroke hole 2032 and is threadedly connected to the front limiting seat 201. Its head size is larger than the width of the stroke hole 2032, thereby slidably constraining the buckle body 203 on the front limiting seat 201 and allowing the buckle body 203 to move vertically along the limiting groove within a limited stroke; when the buckle body 203 is in an unpressed state, its position blocks the front limiting ear 501 that is inserted into the upper limiting groove of the front limiting seat 201 to limit its axial displacement.

[0060] By pressing the pressing part to drive the buckle body 203 to overcome the elastic force of the reset spring 204 and move it downward, the buckle limiting ear 2033 can be disengaged from the obstruction of the front limiting ear 501, thereby achieving unlocking.

[0061] The front limit seat 201 has a baffle in the middle, and the baffle has a slot 601 that can cooperate with the power socket. One side of the slot 601 is directly opposite the power socket, and the other side of the slot 601 has a socket protective cover 6.

[0062] The buckle body 203 is provided with a visual identification area 2031. When it is in the initial locked position under the action of the return spring 204, the visual identification area 2031 is exposed outside the front limit seat 201. When it is pressed down to the unlocked position against the elastic force of the return spring 204, the visual identification area 2031 is covered by the front limit seat 201. The exposed and covered states of the visual identification area 2031 correspond to the locked and unlocked states of the elastic buckle assembly, respectively.

[0063] How this example works

[0064] Eight fixing screws 101 are used to fasten the front limiting seat 201 to the end face 1 of the cabin bulkhead; two return springs 204 are placed into the bottom of the front limiting groove 2011; then, two buckle bodies 203 are inserted into the front limiting groove 2011, and after moderately pressing down the buckle bodies 203, two limiting screws 202 are screwed in; the heads of the limiting screws 202 are recessed into the stroke holes 2032, so that the buckle bodies 203 maintain vertical freedom of movement within a limited stroke. Four fixing screws 101 are used to anchor the middle limiting seat 3 to the end face 1 of the cabin bulkhead.

[0065] The rear limit base 401 is fixed to the end face 1 of the cabin bulkhead using six fixing screws 101; the rear limit buckle 402 is hinged to the rear limit base 401 by two knurled pins 403; finally, two glass ball set screws 404 are screwed in to complete the locking unit assembly.

[0066] Operation status description:

[0067] The buckle body 203 is provided with a visual identification area 2031. When it is in the initial locked position under the action of the return spring 204, the visual identification area 2031 is exposed outside the front limit seat 201. When it is pressed down to the unlocked position against the elastic force of the return spring 204, the visual identification area 2031 is covered by the front limit seat 201. The exposed and covered states of the visual identification area 2031 correspond to the locked and unlocked states of the elastic buckle assembly, respectively.

[0068] The rear limit buckle 402 can rotate around the knurled pin 403 to switch between open and closed states; in the closed state, the head of the glass bead set screw 404 sinks into the locking hole, and resists 20g vibration impact through the ratchet locking effect to prevent accidental loosening.

[0069] Battery assembly process:

[0070] Press down the buckle body 203 to the unlock position (visual identification area 2031 is covered), and simultaneously rotate the rear limit buckle 402 to the open state; place the power supply 5 into the installation area and push it in the direction of the forward limit mechanism 2.

[0071] After the middle battery limiting ear slides into the middle limiting groove 301 and the rear battery limiting ear is inserted into the rear limiting groove 4011, the buckle body 203 is released.

[0072] The buckle body 203 automatically resets (visual identification area 2031 is exposed), and its buckle limiting ear 2033 and front limiting ear 501 form an axial interlock;

[0073] Rotate the rear limit buckle 402 to the closed position to complete the locking.

[0074] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
