Description

Technical Field

[0001] This invention relates to the field of electric power device arrangement and installation technology, specifically a battery pack locking mechanism and an electric vehicle. Background Technology

[0002] The development of new energy electric vehicles is rapid. Current electric vehicle battery installation methods are generally divided into fixed and swappable types. Fixed batteries are typically fixed to the bottom of the vehicle, and the vehicle itself is used for charging. Swappable batteries, on the other hand, are usually fixed to a bracket on the bottom of the vehicle through a movable installation method, allowing them to be removed for replacement or charging. Currently, the fixing methods for swappable new energy vehicle battery packs are mainly divided into two categories: bolt fixing and clip-on fixing.

[0003] Existing bolt-fixing methods require manual or specialized equipment to tighten multiple bolts, which is time-consuming and cannot meet the "minute-level" disassembly and assembly requirements of battery swapping. While snap-on fixing methods are faster, the snaps are prone to wear or deformation after long-term use, leading to increased locking gaps and battery pack swaying during vehicle operation, posing a safety hazard. Furthermore, existing locking mechanisms lack effective locking status feedback, failing to confirm in real-time whether the battery pack is fully locked. Incomplete locking could lead to battery pack detachment, poor circuit contact, and other risks. Therefore, there is an urgent need for a battery pack locking mechanism that combines "fast operation," "stable locking," and "status feedback." Summary of the Invention

[0004] The purpose of this invention is to provide a battery pack locking mechanism and electric vehicle that facilitates improved locking efficiency and sensing and correction of the locking state, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a battery pack locking mechanism, comprising a frame, a storage mechanism, and a locking mechanism. A storage box is fixedly connected to the frame. The storage mechanism includes a storage compartment slidably connected to the inner wall of the storage compartment in a vertical direction. The storage compartment has a storage cavity for storing a battery pack. The storage mechanism is used to store the battery pack. The locking mechanism includes a rotating disk installed in the storage compartment. The rotating disk has multiple sets of sloping panels. An annular groove is formed in the storage compartment. The top surface of the annular groove is sloping and can fit against the top surface of the sloping panels. The storage box is slidable, with a support member at the bottom to support the bottom surface of the storage box. Inside the storage box is a sensing element for detecting the installation status of the storage box. The locking mechanism can sense the installation status of the storage box through the sensing element and control the rotating disk to extend the sloped panel as it rotates within the annular groove. This uniformly raises the top of the storage box while improving locking efficiency. Furthermore, the support member gradually supports the bottom surface of the storage box, enhancing stability during storage, facilitating improved locking efficiency, and allowing for sensing and correction of the locking status.

[0006] Preferably, the locking mechanism further includes an external toothed ring coaxially fixedly mounted on the rotating disk. The rotating disk has multiple sets of sliding grooves evenly distributed on it. The slope panel is slidably connected to the inner wall of the sliding groove in the horizontal direction. An annular cavity is formed at the top center of the storage box. The inner side of the annular groove is connected to the outer side of the annular cavity. The rotating disk can be movably connected to the inner wall of the annular cavity. The storage box is provided with a control component for controlling the movement state of the slope panel.

[0007] Preferably, the control component includes a fixed column fixedly mounted on the frame, a first bevel gear coaxially fixedly connected to the bottom of the fixed column, an external gear ring rotatably connected to the outer wall of the fixed column, a fixed block fixedly connected in the sliding groove, the fixed block being located at one end of the sliding groove near the first bevel gear, a lead screw rotatably connected to the fixed block, the lead screw passing through the ramp panel and threadedly connected to the inner wall of the ramp panel, one end of the lead screw being coaxially fixedly connected to a second bevel gear meshing with the first bevel gear, and a drive component for driving the external gear ring to rotate, facilitating control of the movement state of the ramp panel.

[0008] Preferably, the support includes two sets of sliding frames installed at the bottom of the storage box. The two sets of sliding frames are symmetrically arranged on both sides of the storage box. Guide grooves are provided on both sides of the storage box. The inner walls of the two sides of the sliding frames are slidably connected to the guide grooves in the horizontal direction. A drive plate is fixedly connected to the sliding frame. The frame is provided with a transmission component for synchronously moving the drive plates on both sides in opposite directions when the external gear ring rotates, so as to facilitate the support of the bottom surface of the storage box.

[0009] Preferably, the transmission component includes a bevel gear ring fixedly mounted on the upper side of the external gear ring. The inner wall of the bevel gear ring is rotatably connected to the outer wall of the fixed column. Two sets of third bevel gears are rotatably connected to the frame. The third bevel gears are symmetrically distributed on both sides of the bevel gear ring and mesh with the bevel gear ring. A threaded rod is coaxially fixedly connected to the side of the third bevel gear. The threaded rod is rotatably connected to the frame. The threaded rod passes through the drive plate and is threadedly connected to the drive plate. The threaded directions of the threaded rods on both sides are the same, which facilitates the synchronous reverse movement of the drive plates on both sides when the external gear ring rotates.

[0010] Preferably, a rotating ring is rotatably connected within the annular groove. The inner wall of the rotating ring is uniformly connected to multiple sets of oscillating teeth via a spring-loaded shaft. Multiple sets of helical tooth blocks are uniformly fixedly connected to the outer wall of the rotating ring. Multiple sets of impact rods are slidably connected within the storage box. One end of each impact rod can slide against the outer wall of the rotating ring. A return spring is fixedly connected to the end of each impact rod away from the rotating ring. The end of the return spring away from the impact rod is fixedly connected to the storage box. This allows the rotating disk to rotate in the opposite direction when the storage box is not installed stably, causing the impact rods to vibrate and impact, enabling the storage box to detach from its stuck position and be reinstalled.

[0011] Preferably, the sensing element includes a limiting block fixedly installed on the top of the storage box, and the inner wall of the storage box is provided with a limiting groove that can be inserted into the limiting block. A pressure sensor is fixedly connected in the limiting groove. The pressure sensor is used to sense the pressure when the limiting block is inserted, so as to facilitate the judgment of the installation stability of the storage box.

[0012] Preferably, the driving component includes a drive motor fixedly mounted on the storage box, and the output end of the drive motor is coaxially fixedly connected to a drive gear that meshes with the external gear ring, so as to drive the external gear ring and the bevel gear ring to rotate.

[0013] Preferably, multiple sets of plug-in blocks are evenly fixedly connected to the bottom side of the sliding frame, and multiple sets of plug-in slots that can be plugged into the plug-in blocks are evenly opened on the bottom side of the sliding frame, which facilitates the improvement of the tightness of the seal and the improvement of the support strength at the joint.

[0014] An electric vehicle includes the aforementioned battery pack locking mechanism, which is detachably mounted on the electric vehicle.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention provides a battery pack locking mechanism and an electric vehicle, solving the problems of insufficient battery pack installation and removal efficiency and difficulty in judging and correcting the battery pack installation status in existing battery pack locking mechanisms and electric vehicles. The battery pack is stored through a storage mechanism, and the installation status of the storage box is detected by a sensing element. The locking mechanism controls a rotating disk to extend the ramp panel as it rotates within an annular groove, uniformly raising the top of the storage box while improving locking efficiency. Furthermore, a linkage support element gradually supports the bottom of the storage box, improving stability during storage. When an abnormal battery pack position is detected, the mechanism can quickly assist in fine-tuning and correcting the battery pack position, thus improving battery pack installation efficiency.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-12The diagram illustrates a battery pack locking mechanism, comprising a frame 1, a storage mechanism, and a locking mechanism. A storage box 2 is fixedly connected to the frame 1. The storage mechanism includes a storage box 3 that is slidably connected to the inner wall of the storage box 2 in a vertical direction. The storage box 3 has a storage cavity 4 for storing a battery pack 39. The storage mechanism is used to store the battery pack 39. The locking mechanism includes a rotating disk 5 installed inside the storage box 2. The rotating disk 5 has multiple sets of sloping panels 6. An annular groove 7 is formed inside the storage box 3. The top surface of the annular groove 7 is sloping and can slide against the top surface of the sloping panels 6. The bottom of the storage box 2 has a support member 8 that can support the bottom surface of the storage box 3. The storage box 2 has a sensing member 9 for sensing the installation status of the storage box 3. The sensing member 9 includes a fixed mounting bracket. A limiting block 32 is installed at the top of the storage box 3. The limiting block 32 is located at the four corners of the storage box 3. The inner wall of the storage box 2 has a limiting groove 33 that can be inserted into the limiting block 32. A pressure sensor 34 is fixedly connected in the limiting groove 33. The pressure sensor 34 is used to sense the pressure when the limiting block 32 is inserted. The locking mechanism can sense the installation status of the storage box 3 through the sensing element 9 and control the rotating disk 5 to drive the slope panel 6 to extend out during the rotation in the annular groove 7. This uniformly raises the top of the storage box 3 and improves the locking efficiency. At the same time, the linkage support element 8 gradually supports the bottom surface of the storage box 3, improving the stability during storage. The locking mechanism also includes an external toothed ring 10 coaxially fixedly installed on the rotating disk 5. Multiple sets of sliding grooves 11 are evenly provided on the upper part of the slope panel 6. The inner wall of the sliding groove 11 is slidably connected to the slope panel 6 in the horizontal direction. An annular cavity 12 is provided in the middle of the top of the storage box 3. The annular groove 7 is connected to the annular cavity 12. The rotating disk 5 can be movably connected to the inner wall of the annular cavity 12. The storage box 2 is provided with a control component 13 for controlling the movement state of the slope panel 6. The control component 13 includes a fixed column 14 fixedly installed on the frame 1. The bottom of the fixed column 14 is coaxially fixedly connected to a first bevel gear 15. The external gear ring 10 is rotatably connected to the outer wall of the fixed column 14. A fixed block 16 is fixedly connected in the sliding groove 11. The fixed block 16 is located at the end of the sliding groove 11 near the first bevel gear 15. A lead screw 17 is rotatably connected to the fixed block 16. The lead screw 17 passes through the slope panel 6. The screw 17 is threadedly connected to the inner wall of the slope panel 6. One end of the screw 17 is coaxially fixedly connected to a second bevel gear 18 that meshes with the first bevel gear 15. The storage box 2 is equipped with a drive component 19 for driving the external gear ring 10 to rotate. The drive component 19 includes a drive motor 35 fixedly installed on the storage box 2. The drive motor 35 is preferably a YYHS-40. The output end of the drive motor 35 is coaxially fixedly connected to a drive gear 36 that meshes with the external gear ring 10. By inserting the storage box 3 into the storage box 2 from bottom to top, the top limiting block 32 is inserted into the limiting groove 33, and the rotating disk 5 is inserted into the annular cavity 12. At this time, the slope panel 6 is housed inside the sliding groove 11. Then, the drive motor 35 drives the rotating disk 5 to rotate.While the fixed column 14 and the first bevel gear 15 remain stationary, the second bevel gear 18 rolls on the first bevel gear 15, driving the lead screw 17 to rotate. This pushes out the surrounding sloping panels 6. The top slope of the sloping panels 6 first inserts into the annular groove 7 and fits against the top slope of the annular groove 7. As the sloping panels 6 extend, they gradually lift the storage box 3. During the lifting process, the sloping panels 6 continuously rotate within the annular groove 7. Because the multiple sets of sloping panels 6 extend at the same speed, the storage box 3 is pushed up relatively evenly at all positions, improving the stability during the fixing process.

[0032] Example 2: Please refer to Figures 1-7 This embodiment further illustrates Embodiment 1. The support member 8 shown in the figure includes two sets of sliding frames 20 installed at the bottom of the storage box 2. The two sets of sliding frames 20 are symmetrically arranged on both sides of the storage box 3. The cross-section of the sliding frame 20 is U-shaped. Multiple sets of plug-in blocks 37 are uniformly fixedly connected to the bottom side of the sliding frame 20. Multiple sets of plug-in slots 38 that can plug into the plug-in blocks 37 are uniformly opened on the bottom side of the sliding frame 20. Guide slots 21 are opened on both sides of the storage box 2. The inner walls of both sides of the sliding frame 20 are slidably connected to the guide slots 21 in the horizontal direction. A drive plate 22 is fixedly connected to the sliding frame 20. The frame 1 is provided with a transmission member 23 for synchronously moving in opposite directions with the drive plates 22 on both sides when the external gear ring 10 rotates. The transmission member 23 includes a bevel gear ring 24 fixedly installed on the upper side of the external gear ring 10. The inner wall is rotatably connected to the outer wall of the fixed column 14. Two sets of third bevel gears 25 are rotatably connected to the frame 1. The third bevel gears 25 are symmetrically distributed on both sides of the bevel gear ring 24 and mesh with the bevel gear ring 24. A threaded rod 26 is coaxially fixedly connected to the side of the third bevel gear 25. The threaded rod 26 is rotatably connected to the frame 1. The threaded rod 26 passes through the drive plate 22 and is threadedly connected to the drive plate 22. The threaded directions of the two threaded rods 26 are the same. Since the rotation directions of the two sets of third bevel gears 25 are opposite, the threaded rods 26 on both sides can synchronously drive the sliding frame 20 to slide open and close in opposite directions. The upper surface of the sliding frame 20 can also be provided with a support plate that can be raised and lowered. After the two sliding frames 20 are closed, the support plate is raised and lowered to support the bottom of the storage box 3. When opening the sliding frame 20, the support plate is lowered first.

[0033] Example 3: Please refer to Figures 5-12This embodiment further illustrates Embodiment 1. A rotating ring 27 is rotatably connected within the annular groove 7 shown in the figure. Multiple sets of oscillating teeth 28 are uniformly rotatably connected to the inner wall of the rotating ring 27 via a spring-loaded shaft. Multiple sets of helical tooth blocks 29 are uniformly fixedly connected to the outer wall of the rotating ring 27. Multiple sets of impact rods 30 are slidably connected within the storage box 3. One end of each impact rod 30 is arc-shaped and can slide against the outer wall of the rotating ring 27. A return spring 31 is fixedly connected to the end of the impact rod 30 away from the rotating ring 27. The end of the return spring 31 away from the impact rod 30 is fixedly attached to the storage box 3. The connection is achieved by the slope plate 6 sliding against the inclined side of the swing tooth 28 when rotating in the forward direction, without causing the rotating ring 27 to rotate. However, when the slope plate 6 rotates in the reverse direction, it abuts against the tip of the swing tooth 28, causing the rotating ring 27 to rotate together. This causes the helical tooth block 29 to continuously push the impact rod 30 and, under the push of the return spring 31, to impact the outer wall of the rotating ring 27, causing the storage box 3 to vibrate slightly. This helps to loosen the position where it is stuck, and after the storage box 3 slides down a certain distance, the rotating disk 5 is controlled to rotate in the forward direction again to complete the fixing and locking.

[0034] Furthermore, this application provides an electric vehicle including the aforementioned battery pack locking mechanism, through which the battery pack 39 is detachably connected to the bottom of the electric vehicle. By employing the aforementioned battery pack locking mechanism, the electric vehicle of this application allows the battery pack 39 to be installed and removed more stably and efficiently.

[0035] Working principle: During installation, the storage box 3 containing the battery pack 39 is inserted into the storage box 2 from bottom to top using hydraulic equipment, so that the limiting block 32 at the top corner is inserted into the limiting groove 33, and the rotating disk 5 is inserted into the annular cavity 12. At this time, the slope panel 6 is housed inside the sliding groove 11. Then, the drive motor 35 drives the drive gear 36 to rotate, and the drive gear 36 drives the external gear ring 10 to make the rotating disk 5 rotate as a whole, while the fixed column 14 and the first bevel gear 15 remain stationary, so that the second bevel gear 18 rolls on the first bevel gear 15, driving the lead screw 17 to rotate, thereby pushing out the slope panel 6 from all sides. The top sloping surface of the device will first be inserted into the annular groove 7 and fit against the top sloping surface of the annular groove 7. As the sloping panel 6 extends, it gradually lifts the storage box 3. During the lifting process, the sloping panel 6 will continuously rotate within the annular groove 7. Since the multiple sets of sloping panels 6 extend at the same speed, the storage box 3 is pushed up relatively evenly at all positions, improving the stability during the fixing process. This locking method is more efficient than the traditional screw nut and more flexible than the snap-fit ​​structure. It can drive the battery pack 39 to dock at a uniform speed during the locking process and apply pushing force in all directions, reducing the probability of the storage box 3 tilting and getting stuck on the inner wall of the storage box 2.

[0036] During the rotation of the external gear ring 10, the bevel gear ring 24 will also rotate. The bevel gear ring 24 will drive the third bevel gear 25 on both sides to rotate. The third bevel gear 25 will drive the threaded rod 26 to rotate, driving the drive plates 22 on both sides and the sliding frame 20 to synchronously close towards the middle, thereby blocking the bottom of the storage box 2 and preventing external objects from damaging the battery pack 39 during use. At the same time, when the two sliding frames 20 close, the plug block 37 is inserted into the plug slot 38 on the opposite side, and a sealing gasket can be set at the joint of the sliding frames 20 to improve the sealing performance. The upper surface of the sliding frame 20 can also be provided with a support plate that can be raised and lowered, so that after the two sliding frames 20 close together, the support plate is raised to support the bottom of the storage box 3. When opening the sliding frame 20, the support plate can be lowered first. Support from the bottom can effectively improve the support strength of the battery pack 39 in the storage box 3, reduce the stress on the slope panel 6, and extend the service life of the slope panel 6.

[0037] After storage box 3 is fully inserted into storage box 2, multiple pressure sensors 34 inside the limiting groove 33 sense the pressure value of the limiting block 32 during insertion to determine if tilting has occurred. When the error in the force values ​​of the four pressure sensors 34 is within the set range, it indicates that the installation is relatively stable. When the difference is large, it indicates that storage box 3 may be tilted. At this time, it is necessary to control the rotating disk 5 to rotate in the opposite direction. The tip of the slope plate 6 will then abut against the tip of the swing tooth 28, causing the rotating ring 27 to rotate together. This causes the helical tooth block 29 to continuously push the impact rod 30 and, under the push of the return spring 31, impact the outer wall of the rotating ring 27, thus causing the storage box to tilt. Slight vibration of storage box 3 helps to loosen its jammed or tilted position. As the slope panel 6 retracts into the sliding groove 11, storage box 3 slides down a certain distance. Then, the rotating disk 5 is controlled to rotate forward again to lift and lock storage box 3, thus completing the auxiliary correction of storage box 3. If the above operation is repeated and the abnormality is still displayed, manual inspection of the position of storage box 2 and storage box 3 and the deformation of the box body is required. Since the vehicle body itself will vibrate to a certain extent during driving, the impact of the impact rod 30 set inside the mechanism is only used to assist the storage box 3 in resetting and will not damage the battery pack 39.
