Description

Technical Field

[0001] This utility model belongs to the technical field of baking and lighting devices, specifically, it relates to an automatic opening and closing baking and lighting device with a detachable battery and mechanical positioning. Background Technology

[0002] Automatic opening and closing supplemental lighting devices for tobacco curing are key auxiliary equipment in tobacco curing barns. Their function is to automatically unfold the lamp panels according to the process rhythm during the curing stage, providing a uniform and observable spectrum to the tobacco leaves, promoting chlorophyll degradation and internal substance transformation, thereby shortening the curing cycle and improving the color of the finished product. Traditional devices typically fix the lamp panels to simple hinges, using a built-in geared motor to drive a connecting rod for rotation; the energy source uses a non-removable lithium battery built into a sealed box, with the charging interface exposed to high temperature and humidity; the positioning method relies solely on a motor encoder or Hall effect counter, with the controller immediately cutting off the motor when the number of pulses reaches a set value, keeping the lamp panel at the theoretical angle. While the entire system appears to achieve "automatic opening and closing," in reality, the various functional modules are isolated, lacking system-level adaptation to the harsh conditions of the curing barn. First, the built-in battery cannot be quickly replaced on-site. Once the battery is depleted, the entire machine must be powered off and moved out of the curing chamber for charging, causing the curing process to be interrupted. Second, the single electronic positioning will accumulate errors after long-term operation, and in the event of a sudden power outage, the motor will lose its holding force, and the lamp panel will slide down due to its own weight, causing the illumination angle to shift or even hitting the tobacco leaves. Third, high-temperature airflow containing tar can easily enter the electrical cavity along the hinge gaps, inducing contact corrosion, bearing jamming, and insulation failure, resulting in a high maintenance frequency. Utility Model Content

[0003] In view of this, the present invention provides an automatic opening and closing baking and supplemental lighting device with a detachable battery and mechanical positioning, which solves the problem of how to quickly replace the battery on the baking and supplemental lighting site without stopping the machine or using tools, and can still maintain the unfolded angle of the lamp panel in the event of power failure or control system failure, so as to achieve continuous, reliable and maintenance-free automatic opening and closing supplemental lighting.

[0004] This utility model is implemented as follows:

[0005] This utility model provides an automatic opening and closing baking and lighting device with a removable battery and mechanical positioning, comprising:

[0006] A lamp body assembly having a light-emitting surface and a back surface opposite to the light-emitting surface;

[0007] A rotary drive mechanism, comprising a rotary output end and a fixed support, wherein the rotary output end is rigidly connected to the back of the lamp body assembly, and the fixed support is located on the outer side of the back of the lamp body assembly and surrounds the rotary output end around the rotation axis;

[0008] A removable battery module, the removable battery module comprising:

[0009] The battery compartment is formed as a blind hole-shaped accommodating space that is recessed from the outer wall of the fixed support along the direction perpendicular to the axis of rotation, with the opening facing the outside of the device.

[0010] The battery pack is an integrally enclosed elongated oval shell, with the outer contour of the shell slidingly engaging with the inner contour of the battery compartment. One end of the shell is provided with a handle, and the other end is provided with a conductive end face.

[0011] A quick connector is fixed to the bottom of the battery compartment and has an elastic contact that is complementary to the conductive end face of the battery pack. When the battery pack is pushed in along the axis of the battery compartment, the elastic contact is pressed against the conductive end face to form an electrical connection.

[0012] The mechanical lock includes an elastic flange disposed on the side wall of the battery pack housing and a corresponding recess disposed at the opening of the battery compartment. When the battery pack is fully inserted, the elastic flange engages with the recess to form a lock that can be released by hand.

[0013] A mechanical positioning mechanism, comprising:

[0014] The positioning disk is coaxially fixed to the rotating output end and rotates synchronously with the lamp body assembly. The end face of the positioning disk is provided with spherical recesses distributed around the rotation axis.

[0015] The spring top ball is installed on the wall of the fixed support facing the positioning disk along the rotation axis. Its steel ball end always abuts against the end face of the positioning disk under the spring preload. When the lamp body assembly rotates to the preset angle, the steel ball is embedded in the corresponding spherical recess to form a mechanical limit.

[0016] The technical advantages of this utility model for an automatic opening and closing baking supplementary lighting device with a detachable battery and mechanical positioning are as follows: By integrating the detachable battery module and the mechanical positioning mechanism into the same fixed support, operators can complete "non-stop power replacement" by simply inserting and removing the battery pack with one hand in the field. At the same time, when the lamp body rotates to 0° or 90°, the steel ball automatically falls into the pit, producing a clear "click" feel, forming an absolute mechanical limit that can be maintained without electricity. This eliminates the risk of position drift when the traditional pure motor positioning loses power or steps, and achieves true "unlimited battery life" and "plug and play", greatly improving the continuity and reliability of tobacco baking supplementary lighting operations.

[0017] Based on the above technical solution, the automatic opening and closing baking and lighting device with a detachable battery and mechanical positioning of this utility model can be further improved as follows:

[0018] The battery compartment has a sealing flange around its opening. The surface of the sealing flange facing outward is a continuous plane, which is used to press and cooperate with the annular sealing rib inside the battery pack handle to form a dustproof and moisture-proof barrier for the battery compartment.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the sealing flange surrounding the hatch and the annular sealing rib on the inside of the battery pack handle are pressed together at the moment of locking, forming a continuous barrier without breaks, preventing moisture, smoke and pesticide particles from entering the battery compartment, avoiding contact corrosion or short circuit, and enabling the device to maintain stable electrical connection for a long time in the high humidity and high dust oven environment, reducing the frequency of maintenance.

[0020] Furthermore, the elastic contact of the quick connector is a copper alloy leaf spring assembly. The leaf spring assembly is evenly arranged circumferentially along the bottom of the battery compartment and extends obliquely towards the hatch opening. The conductive end face of the battery pack is a copper-plated plane. During the insertion of the battery pack, the leaf spring assembly is synchronously slid and pressed by the conductive end face and generates an elastic force perpendicular to the insertion direction to maintain continuous surface contact.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the copper alloy leaf spring assembly is synchronously slid and pressed by the conductive end face during the battery pack insertion process, and generates an elastic force perpendicular to the insertion direction, so that the contacts always maintain a face-to-face pressing state. Even if the device is continuously micro-moving due to fan vibration during the baking process, the elastic compensation of the leaf spring can automatically eliminate the contact gap, prevent arc erosion, and ensure the long-term reliability of high current transmission.

[0022] Furthermore, the elastic flange of the mechanical latch is a cantilevered plastic tongue, the root of which is integrally formed with the battery pack shell. A wedge-shaped protrusion is provided on the outer side of the free end of the tongue, and the corresponding recess at the battery compartment opening is a window that penetrates the wall thickness of the fixing support. The wedge-shaped protrusion pops out and is exposed in the window when the battery pack is inserted into place, forming a dual visual and tactile prompt.

[0023] The cantilevered plastic tongue is made of glass fiber reinforced nylon 6 (PA6-GF30).

[0024] Furthermore, the outer peripheral wall of the positioning disk is provided with an annular step, and an annular wear-resistant pad is sandwiched between the end face of the step facing the fixed support and the fixed support. The wear-resistant pad provides axial preload and reduces end face wear when the positioning disk rotates.

[0025] The annular wear-resistant pad is formed by stamping 316L stainless steel foil.

[0026] Furthermore, the mounting hole of the spring top ball is a stepped threaded hole opened from the outer wall of the fixed support along the rotation axis. The large diameter section of the stepped threaded hole faces the outside of the device and accommodates the adjusting nut. The adjusting nut is used to change the spring compression to adjust the abutment force of the steel ball on the positioning plate.

[0027] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the combination of stepped threaded hole and adjusting nut allows the contact force of steel ball against positioning plate to be adjusted on the assembly site in real time with a screwdriver. It can not only set a suitable "click" feel when the machine is new, but also quickly compensate for the preload after long-term use due to spring fatigue. The original positioning quality can be restored without replacing parts, reducing the life cycle maintenance cost.

[0028] Furthermore, the back of the lamp body assembly is provided with an annular boss coaxial with the rotating output end. A sealing ring is sandwiched between the outer wall of the annular boss and the inner wall of the fixed support. The sealing ring maintains a sliding seal throughout the rotation of the lamp body assembly, preventing external dust from entering the interior of the rotating drive mechanism.

[0029] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the silicone sealing ring between the annular boss on the back of the lamp body and the inner wall of the fixed support maintains a sliding seal throughout the rotation process, forming a dynamic barrier to prevent hot air containing tar in the drying oven from entering the interior of the rotating drive mechanism, avoids the motor bearing from getting stuck due to tar condensation, extends the drive life, and at the same time ensures that the lamp body rotates smoothly and without noise.

[0030] Furthermore, the bottom of the battery compartment is provided with a mechanical anti-reverse insertion rib arranged alongside the quick connector. The anti-reverse insertion rib extends along the battery pack insertion direction, and the corresponding position of the battery pack housing is provided with a guide groove of complementary shape. The guide groove slides in cooperation with the anti-reverse insertion rib to prevent the battery pack from being inserted in reverse.

[0031] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the anti-reverse insertion rib at the bottom of the battery compartment and the battery pack guide groove form a unique geometric channel, which ensures that the battery pack can only be inserted in the correct posture, completely eliminating short circuits or arcing of contacts caused by reverse or skewed insertion, realizing "foolproof" battery swapping, and even at night without lighting, the operation can be completed by feel, improving the safety of field operations.

[0032] Furthermore, the edge of the light-emitting surface of the lamp assembly is provided with a flexible light-shielding lip that surrounds the light-emitting surface. The flexible light-shielding lip expands outward when the lamp assembly is rotated to the working state to block lateral stray light and prevent the light-emitting surface from making hard contact with external objects.

[0033] The flexible light-shielding lip is a food-grade silicone ring.

[0034] Furthermore, it also includes an energy and control mechanism, which is equipped with:

[0035] The main control circuit board is attached and fixed to the inner wall of the fixed support and located next to the rotary drive mechanism. The main control circuit board is electrically connected to the quick connector through wires to obtain the power of the removable battery module.

[0036] A motor drive circuit is arranged on the main control circuit board and connected to the stator winding of the motor of the rotary drive mechanism via a flexible cable. It is used to receive control signals from the main control circuit board to drive the lamp body assembly to rotate.

[0037] An angle sensing circuit includes a magnetic element fixed around the positioning disk and a Hall element fixed to a fixed support. The Hall element is electrically connected to the main control circuit board and is used to provide the main control circuit board with a real-time angle signal of the lamp assembly. The main control circuit board controls the motor drive circuit to start and stop according to the signal, and together with the mechanical positioning mechanism, realizes the dual positioning of the lamp assembly at a preset angle.

[0038] The main control circuit board uses STMicroelectronics STM32F103C8T6 (ARM Cortex-M3, 72 MHz, 64 KB Flash) as the main MCU. It integrates multiple PWM, ADC and I²C interface on the chip, which can directly receive Hall angle signals and output motor drive PWM.

[0039] The motor drive circuit uses the TI DRV8873H 5-A peak H-bridge chip, which has built-in overcurrent and overtemperature protection, and is connected to the stator winding of the DC geared motor via a flexible FPC cable.

[0040] The angle sensing circuit uses the Hall effect angle sensor TLE5012B (Infineon).

[0041] The aforementioned chip combination has been commercially matured in angle servo applications such as smart gimbals and electric clamps, and can be directly adapted to this device.

[0042] The energy and control mechanism utilizes a mature combination of an STM32 main control board, a DRV8873H driver chip, and a TLE5012B Hall angle sensor to read the positioning disk angle in real time and cross-verify it with the position of the mechanical recess. The motor PWM output stops the instant the steel ball falls into the recess, achieving dual "electrical-mechanical" confirmation and completely eliminating overshoot or loss of synchronization. The entire control unit is fitted and fixed to the inner wall of the fixed support, sharing the same support with the battery compartment, reducing the length of the wiring harness and the number of connectors. During assembly, only two standard FPC cables need to be plugged and unplugged to complete the electrical connection, simplifying production and after-sales maintenance. This allows the device to maintain high reliability while also offering the advantages of low cost and rapid mass production.

[0043] Compared with existing technologies, the advantages of this utility model's automatic opening and closing baking and lighting device with a detachable battery and mechanical positioning are as follows: This utility model redesigns the topological relationship of the three major subsystems—energy, positioning, and sealing—within the device, making "uninterrupted operation during battery swapping," "no displacement during power outages," and "no corrosion at high temperatures" a reality. By placing the battery compartment externally and using a rail-type quick connector, operators can pre-charge the spare battery pack outside the baking chamber and perform single-handed insertion and removal, just like changing a tool battery. The device can continue to operate without power interruption, fundamentally eliminating baking interruptions caused by charging wait times. The mechanical positioning mechanism provides an absolute holding force for the lamp panel, independent of electricity, through a purely physical engagement of a spring-loaded ball and a spherical recess. Regardless of whether the controller is working, the lamp panel can be firmly locked at the two key angles of retraction and unfolding with a "click," avoiding the accumulation of electronic errors and eliminating the risk of slippage during power outages, ensuring that the lighting angle remains accurate even after multiple opening and closing cycles. The detachable battery module and the rotary drive mechanism are separated by the same sealing flange and dynamic sealing ring. The battery compartment and the electrical cavity form an independent isolated chamber, preventing high-temperature tar-containing airflow from penetrating the contacts and bearings, significantly reducing corrosion and wear rates and extending the overall lifespan of the device. Since all maintenance interfaces face outwards, operators can visually inspect the latch status, adjust spring preload, or replace wear-resistant gaskets without disassembling the device. Maintenance time has been reduced from several hours to just a few minutes, significantly reducing labor intensity. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0052] like Figures 1-4 The image shown is an example diagram of an automatic opening and closing baking and lighting device with a removable battery and mechanical positioning provided by this utility model, comprising:

[0053] The lamp body assembly 10 has a light-emitting surface and a back surface opposite to the light-emitting surface;

[0054] The rotary drive mechanism 20 includes a rotary output end and a fixed support. The rotary output end is rigidly connected to the back of the lamp body assembly 10, and the fixed support is located on the outside of the back of the lamp body assembly 10 and surrounds the rotary output end around the rotation axis.

[0055] The removable battery module 30 includes:

[0056] Battery compartment 31 is formed as a blind hole-shaped accommodating space that is recessed from the outer wall of the fixed support along the direction of rotation perpendicular to the axis of rotation, with the hatch facing the outside of the device.

[0057] The battery pack 32 is an overall enclosed elongated oval shell. The outer contour of the shell slides in conjunction with the inner contour of the battery compartment 31. One end of the shell is provided with a handle, and the other end is provided with a conductive end face.

[0058] Quick connector 33 is fixed to the bottom of battery compartment 31 and has an elastic contact that is complementary to the conductive end face of battery pack 32. When battery pack 32 is pushed in along the axis of battery compartment 31, the elastic contact is pressed against the conductive end face to form an electrical connection.

[0059] The mechanical latch includes an elastic flange provided on the side wall of the battery pack 32 housing and a corresponding recess provided at the opening of the battery compartment 31. When the battery pack 32 is fully inserted, the elastic flange engages with the recess to form a lock that can be released by hand.

[0060] Mechanical positioning mechanism 40, which includes:

[0061] The positioning disk is coaxially fixed to the rotating output end and rotates synchronously with the lamp body assembly 10. The end face of the positioning disk is provided with spherical recesses distributed around the rotation axis.

[0062] The spring ball is installed on the wall of the fixed support facing the positioning plate along the rotation axis. Its steel ball end always abuts against the end face of the positioning plate under the spring preload. When the lamp body assembly 10 rotates to the preset angle, the steel ball is embedded in the corresponding spherical recess to form a mechanical limit.

[0063] In the above technical solution, the outer periphery of the hatch of the battery compartment 31 is provided with a sealing flange surrounding the hatch. The surface of the sealing flange facing the outside of the device is a continuous plane, which is used to press and cooperate with the annular sealing rib inside the handle of the battery pack 32 to form a dustproof and moisture-proof barrier for the battery compartment 31.

[0064] Furthermore, in the above technical solution, the elastic contact of the quick connector 33 is a copper alloy leaf spring assembly. The leaf spring assembly is evenly arranged circumferentially along the bottom of the battery compartment 31 and extends obliquely towards the hatch opening. The conductive end face of the battery pack 32 is a copper-plated plane. During the insertion of the battery pack 32, the leaf spring assembly is synchronously slid and pressed by the conductive end face and generates an elastic force perpendicular to the insertion direction to maintain continuous surface contact.

[0065] Furthermore, in the above technical solution, the elastic flange of the mechanical lock is a cantilevered plastic tongue. The root of the tongue is integrally formed with the shell of the battery pack 32. A wedge-shaped protrusion is provided on the outer side of the free end of the tongue. The corresponding recess at the opening of the battery compartment 31 is a window that penetrates the wall thickness of the fixing support. The wedge-shaped protrusion pops out and is exposed in the window when the battery pack 32 is inserted into place, forming a dual visual and tactile prompt.

[0066] Furthermore, in the above technical solution, the outer peripheral wall of the positioning disk is provided with an annular step, and an annular wear-resistant pad is sandwiched between the end face of the step facing the fixed support and the fixed support. The wear-resistant pad provides axial preload and reduces end face wear when the positioning disk rotates.

[0067] Furthermore, in the above technical solution, the mounting hole of the spring top ball is a stepped threaded hole opened from the outer wall of the fixed support along the direction of the rotation axis. The large diameter section of the stepped threaded hole faces the outside of the device and accommodates the adjusting nut. The adjusting nut is used to change the spring compression to adjust the abutment force of the steel ball on the positioning plate.

[0068] Furthermore, in the above technical solution, the back of the lamp body assembly 10 is provided with an annular boss coaxial with the rotating output end. A sealing ring is sandwiched between the outer wall of the annular boss and the inner wall of the fixed support. The sealing ring maintains a sliding seal throughout the rotation of the lamp body assembly 10, preventing external dust from entering the interior of the rotating drive mechanism 20.

[0069] Furthermore, in the above technical solution, the bottom of the battery compartment 31 is provided with a mechanical anti-reverse insertion rib arranged in parallel with the quick connector 33. The anti-reverse insertion rib extends along the insertion direction of the battery pack 32. The corresponding position of the battery pack 32 housing is provided with a guide groove of complementary shape. The guide groove slides in cooperation with the anti-reverse insertion rib to prevent the battery pack 32 from being inserted in reverse.

[0070] Furthermore, in the above technical solution, the edge of the light-emitting surface of the lamp assembly 10 is provided with a flexible light-shielding lip that surrounds the light-emitting surface. The flexible light-shielding lip expands outward when the lamp assembly 10 is rotated to the working state, in order to block lateral stray light and prevent the light-emitting surface from making hard contact with external objects.

[0071] Furthermore, the above technical solution also includes an energy and control mechanism, which is equipped with:

[0072] The main control circuit board is attached and fixed to the inner wall of the fixed support and located next to the rotary drive mechanism 20. The main control circuit board is electrically connected to the quick connector 33 through wires to obtain the power of the detachable battery module 30.

[0073] The motor drive circuit is arranged on the main control circuit board and connected to the stator winding of the motor of the rotary drive mechanism 20 via a flexible cable. It is used to receive control signals from the main control circuit board to drive the lamp body assembly 10 to rotate.

[0074] An angle sensing circuit includes a magnetic element fixed around the positioning disk and a Hall element fixed to the fixed support. The Hall element is electrically connected to the main control circuit board and is used to provide the main control circuit board with a real-time angle signal of the lamp assembly 10. The main control circuit board controls the motor drive circuit to start and stop according to the signal, and together with the mechanical positioning mechanism 40, achieves dual positioning of the lamp assembly 10 at a preset angle.

[0075] Specific Implementation Example 1: This embodiment adopts a single-sided cantilever and quick-connect battery layout, suitable for standardized tobacco loading channels in newly built dense curing barns. The fixed support is directly suspended below the I-beam of the curing barn top by four expansion bolts, with the rotation axis parallel to the tobacco hanging beam; the battery compartment opening faces the outside of the channel, 1.8 meters above the ground, allowing operators to complete battery swapping while standing on the ground. The battery pack uses cylindrical lithium iron phosphate cells, encapsulated in an ABS+PC alloy shell with a handle, with an overall "flat elliptical" cross-section, forming a clearance fit with the elliptical blind hole of the battery compartment; three copper alloy leaf springs are arranged at the bottom of the compartment, with silver-plated surfaces. When the battery pack is pushed in, the copper-plated plane of the conductive end face first obliquely slides against the leaf springs, and the elastic deformation of the leaf springs generates a surface pressure of about ten Newtons, ensuring low-resistance contact even under continuous vibration. The mechanical latch is a single-point cantilevered tongue, with the base of the tongue integrally injection molded with the battery pack housing. The free end has a wedge-shaped protrusion with a height of two millimeters. When the battery pack is pushed to the end, the protrusion engages with the rectangular window of the hatch and protrudes outwards. The operator can unlock it by pressing the protrusion with their finger. The entire battery swapping process requires no tools and takes about five seconds. The rotary drive mechanism uses a combination of a DC geared motor and a planetary gearbox. The output flange is rigidly connected to the back of the lamp body by four high-strength bolts. The positioning plate is an aluminum disc that is coaxially locked with the output flange. Two spherical recesses are milled on the end face of the disc, corresponding to the zero-degree storage and ninety-degree working angles, respectively. Stainless steel spring balls are screwed into the corresponding positions of the fixed support, and the preload can be finely adjusted by the external hexagonal nut. When the lamp body unfolds, the motor initially rotates at a constant speed. When the Hall element detects that the magnetic element is approaching 90 degrees, the controller reduces the PWM duty cycle to decelerate the motor. The moment the positioning disc's recess aligns with the steel ball, the ball snaps into place under the action of the spring. The sudden increase in motor current is detected by the controller and immediately cuts off. The lamp panel is mechanically fixed in place, ensuring it won't fall even if the curing barn experiences an unexpected power outage. The edge of the luminous surface features a vulcanized, one-piece molded silicone lip with a duckbill-shaped cross-section. When the lamp body unfolds horizontally, the lip droops naturally, blocking stray light from the sides and preventing direct glare from the operator's eyes. Simultaneously, the silicone's softness allows for elastic deformation upon accidental impact with tobacco leaves, preventing scratches. The entire device weighs less than eight kilograms, allowing for installation and wiring by a single worker. It is suitable for newly built curing barns with high ceilings and wide passageways, enabling "immediate installation and use, with no downtime during power changes."

[0076] Specific Implementation Example 2: This embodiment adopts a double-sided support and horizontal battery insertion layout, specifically designed for the renovation of low-ceilinged spaces in old drying ovens. The clear height under the beams in old drying ovens is typically only 1.6 meters, and the top is already covered with insulation, making it unable to withstand cantilever loads. Therefore, two short cantilever supports are symmetrically installed on both sides of the original load-bearing wall. The hollow shaft of the rotary drive mechanism passes through the two supports, forming a double-bearing structure with support at both ends, significantly reducing single-point bending moments. The battery compartment is horizontally arranged on the outside of the right-side support, with the hatch facing forward. Operators can pull out the battery pack horizontally like a drawer without having to raise their arms, conforming to ergonomics. The battery pack cross-section is changed to a "square with rounded corners," matching the square-hole guide rails of the battery compartment to prevent accidental rotation. The conductive end face uses gold-plated copper busbars, which connect with the elastic pin array inside the compartment. The pin array base is made of high-temperature resistant PPS plastic, which can withstand long-term ambient temperatures above 80 degrees Celsius in the drying oven without softening. The mechanical locking mechanism has been replaced with symmetrical elastic flanges on both sides, made of fiberglass-reinforced nylon. The flanges have a decreasing thickness at the base, forming a cantilever. When inserted, both flanges slide simultaneously across the hatch ramp, and pop out synchronously with a double "click" sound, providing both audible and tactile confirmation, allowing for successful locking even in noisy environments. The positioning plate is designed separately from the lamp body. The positioning plate is fixed to the outer wall of the hollow shaft by an expansion sleeve, facilitating on-site angle adjustment. The number of recesses has been increased to four evenly distributed around the circumference, corresponding to 0 degrees, 45 degrees, 90 degrees, and 135 degrees, meeting the needs of old drying rooms with varying beam spacing requiring multiple lighting angles. The spring top ball uses a stainless steel ball screw with a PTFE coating on the head, reducing friction noise with the aluminum positioning plate. The lamp body uses a split aluminum extrusion profile, with a silicone sealing strip embedded in the groove on the back, forming an axial seal with the end faces of the side supports to prevent tar-containing hot air from entering the bearings. The light-emitting surface no longer has an overall light-shielding lip; instead, micro silicone light-shielding caps are applied to the edge of each LED lens, achieving the same anti-glare effect while reducing wind resistance, making it suitable for low-ceilinged spaces with swirling airflow. Due to the double-sided support structure sharing the load, the entire device can support a heavier red LED array, making it suitable for upgrading old drying ovens that require increased light intensity. On-site installation only requires removing the original fixed lamp post and utilizing existing wall holes, shortening the construction period to half an hour and enabling rapid deployment for "simultaneous drying and modification."

[0077] Specifically, the principle of this invention is as follows: the device uses a fixed support as a geometric reference, and arranges the rotation axis, battery sliding axis, and sealing interface orthogonally, so that any functional action revolves around the same rigid frame, thereby avoiding the superposition of tolerances caused by multiple references. During battery swapping, the battery pack slides straight into the battery compartment along the guide rail. At the end of the sliding, the conductive end face simultaneously squeezes the copper alloy leaf spring assembly. The elastic deformation of the leaf spring automatically compensates for manufacturing and wear gaps, forming continuous surface contact, and realizing the simultaneous completion of electrical conduction and mechanical locking. The cantilevered tongue generates an elastic jump at the moment the battery pack is in place, and the wedge-shaped protrusion is locked into the window and exposed, providing tactile feedback and forming a secondary anti-disengagement protection, so that the locking remains reliable even under vibration. The rotary drive mechanism outputs torque to rotate the lamp panel. The positioning disk rotates synchronously with the lamp panel. When the spherical recess rotates to the position where the steel ball is directly opposite, the spring potential energy is released instantaneously, and the steel ball is pressed into the recess, generating radial mechanical resistance. This resistance is much greater than the self-locking torque of the motor gearbox, thus achieving angle maintenance without consuming current. When the controller receives the next command, the motor first outputs a breakthrough torque to overcome the resistance of the steel ball coming out, and then enters a constant speed range. When the Hall sensor detects that the angle of the magnetic element is close to the target, it decelerates in advance. The moment the motor stops, the steel ball falls back into the corresponding recess. Electronic and mechanical dual confirmation ensures that the lamp panel stops accurately. In terms of sealing, the sealing flange of the battery compartment and the ring rib of the handle are compressed when the latch is engaged, forming a continuous barrier without any breaks. A silicone sealing ring is set between the ring boss on the back of the lamp body and the inner wall of the fixed support, which maintains a sliding seal throughout the rotation process, isolating the hot air containing tar outside the electrical cavity, so that the contacts, bearings and control board are always in a relatively clean environment. This achieves system-level synergy of "battery replacement without disassembly, positioning without power consumption, and sealing without aging", and finally allows the automatic opening and closing baking supplement light device to be plug-and-play and maintenance-free for a long time under real baking oven conditions, just like a household appliance.
