Description

Technical Field

[0001] This invention relates to the field of optical observation device technology, and more specifically, to a telescopic and flipping actuator for an environmental perception camera used in electric delivery vehicles. Background Technology

[0002] The environmental perception camera of the electric delivery vehicle is an optical observation device that is fixed or movable and installed on the outside of the vehicle. It can collect images around the vehicle in real time and provide information such as blind spots in front and behind, narrow alleys on the sides and low obstacles, thereby assisting the vehicle to drive safely at low speed in narrow areas such as residential areas and streets.

[0003] The existing environmental perception camera for electric delivery vehicles mainly consists of large components such as optical lens modules, protective housings, and fixed or movable mounting bases. Its function is to replace or supplement traditional rearview mirrors, expand the driver's field of vision for complex road conditions such as blind spots and narrow alleys, and assist the vehicle in safe driving at low speeds and precise parking.

[0004] The environmental perception cameras equipped on existing electric delivery vehicles often experience problems in actual operation. When the vehicle travels on long slopes or sloping sections of underground parking garages, the entire vehicle tilts and the camera rotates synchronously with the vehicle. As a result, the camera can only capture images of the ground or sky, significantly reducing the effective field of view of the surrounding environment. This leads to a deterioration in the environmental perception and recognition effect, seriously interfering with vehicle repositioning, cargo loading and unloading, and other operations, directly reducing the overall efficiency of the vehicle's environmental perception operations.

[0005] Based on this, the present invention discloses an environmental perception camera telescopic and flipping actuator for electric delivery vehicles. Summary of the Invention

A pressing curved plate is fixedly connected to the top of the connecting slide column.

[0010] As a further improvement to this technical solution, a pair of limiting sliding pillars are fixedly connected to both sides of the delivery vehicle body. A connecting side plate is slidably connected to the outer wall of the pair of limiting sliding pillars. A protective side box is fixedly connected to the side wall of the connecting side plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the retractable and tilting actuator of the environmental perception camera used in electric express delivery vehicles, the entire vehicle-mounted camera actuator works in coordination with the buffer component and the adaptive leveling component. This can alleviate the problem of the vehicle tilting and tilting when the express delivery vehicle is traveling on long slopes or sloping sections of underground parking garages, and the problem of the perception camera tilting synchronously with the vehicle body. It can improve the shortcomings of traditional vehicle-mounted camera equipment that only captures the ground or sky, lacks effective field of view around the vehicle, and reduces the accuracy of environmental recognition. This is conducive to improving the efficiency of the vehicle's surrounding environment perception operation when the express delivery vehicle is moving or loading and unloading goods.

[0018] 2. In the retractable and tilting actuator of the environmental sensing camera used in electric express delivery vehicles, when the entire camera assembly is retracted into the storage slot two, the outer wall of the extrusion curved plate and the inner wall of the extrusion cone column press against each other, pushing the connecting slide column downwards, so that the retaining ring is embedded in the retaining groove. The bottom end of the retaining ring presses and rubs against the outer surface of the sliding ring, thus locking and limiting the fixed ball. This locking structure helps to reduce the random shaking of the sensing camera housing and sensing camera body inside the storage slot two when idle, reduces the meaningless reciprocating rotation of the center of gravity adjustment mechanism when not in operation, extends the service life of the entire mechanism, and stabilizes the working performance of the equipment.

[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] In actual operation, when vehicles travel on long slopes or sloping sections of underground parking garages, the entire vehicle tilts and pitches. The camera tilts synchronously with the vehicle body, and the captured image can only capture the ground or sky. The effective field of view of the surrounding environment is greatly lost, the environmental perception and recognition effect is deteriorated, and it seriously interferes with vehicle relocation, cargo loading and unloading and other operations, directly reducing the efficiency of the vehicle's environmental perception operation.

[0032] Therefore, the present invention provides an environmental perception camera telescopic and flipping actuator for electric delivery vehicles. See [link to related document]. Figures 1-6 As shown, the device includes a delivery vehicle body 1. Both sides of the delivery vehicle body 1 have storage slots 11. The bottom of each pair of storage slots 11 has a second storage slot 12. A telescopic electric cylinder 13 is fixedly connected to the bottom inner side of each storage slot 11. A telescopic rod 14 is fixedly connected to the output end of the telescopic electric cylinder 13. A sensing camera housing 15 is located on the side of the telescopic rod 14 away from the delivery vehicle body 1. Sensing camera bodies 16 are located on both sides of the sensing camera housing 15. A buffer assembly is located at the end of the telescopic rod 14 away from the telescopic electric cylinder 13, which is used to buffer the sensing camera housing 15 from compression and impact. An adaptation assembly is located on the top of the sensing camera housing 15, which is used to adaptively adjust the sensing camera housing 15 according to the tilt and weight of the entire vehicle to maintain a horizontal shooting state.

[0033] The buffer assembly includes a connecting cylinder 3, which is slidably connected to the outside of the telescopic rod 14. A buffer spring 32 is fixedly connected to the inner side of the connecting cylinder 3 away from the telescopic electric cylinder 13. The buffer spring 32 is connected to the end of the telescopic electric cylinder 13. Multiple sets of material reduction grooves 31 are opened on the outer wall of the connecting cylinder 3.

[0034] The adaptation component includes a fixed rod 2, which is rotatably connected to the end of the connecting cylinder 3 away from the telescopic electric cylinder 13. Both outer walls of the fixed rod 2 are fixedly connected to connecting rotating plates 21. A pair of connecting rotating plates 21 are fixedly connected to a fixed rotating ring 22 at one end close to each other. The top of the fixed rotating ring 22 is provided with a slot 23. A sliding ring 24 is slidably connected to the inner side of the fixed rotating ring 22. A fixed ball 25 is fixedly connected to the inner wall of the sliding ring 24. The fixed ball 25 is located inside the fixed rotating ring 22. Both sides of the fixed ball 25 are fixedly connected to connecting arms 26. The bottom of a pair of connecting arms 26 is connected to the bottom of the sensing camera housing 15. A counterweight 27 is fixedly connected to the bottom of the sensing camera housing 15.

[0035] During operation, when it is necessary to extend the sensing camera housing 15 and the sensing camera body 16 outward to conduct panoramic sensing and observation of the external environment surrounding the delivery vehicle body 1, the telescopic electric cylinder 13 can be activated. The telescopic electric cylinder 13 can extend outward synchronously with the fixed rod 2 through the telescopic rod 14, connecting cylinder 3, buffer spring 32, and fixed rod 2, so as to achieve the effect of extending the sensing camera housing 15 and the sensing camera body 16 to collect images. After the vehicle has completed the loading and unloading of goods and the relocation operation, the staff can also activate the telescopic electric cylinder 13 in reverse to drive the sensing camera housing 15 and the sensing camera body 16. The main body 16 retracts into the storage compartment 12 for storage. When the delivery vehicle body 1 travels to a slope with left and right inclinations, the counterweight 27, due to its own weight, can rotate within the fixed rotating ring 22 via the interaction of the fixed ball 25 and the sliding ring 24, thereby achieving left and right horizontal adjustment of the sensing camera housing 15 and the sensing camera body 16. When the delivery vehicle body 1 travels to a slope with front and rear inclinations, the counterweight 27, relying on its own center of gravity, pulls the fixed rod 2 to rotate synchronously, thereby achieving horizontal adjustment of the sensing camera housing 15 and the sensing camera body. The front and rear horizontal adjustment of the 16 allows for adaptive tilting and leveling of the vehicle-mounted camera equipment, adapting to various sloping road conditions. Multiple sets of material-reducing grooves 31 are opened on the outer wall of the connecting cylinder 3 to reduce its overall weight, helping to alleviate the load on the connection point between the telescopic rod 14 and the connecting cylinder 3. When external objects, walls, or the fixed rod 2 or counterweight 27 come into rigid contact with the vehicle during operation, the connecting cylinder 3 can slide along the telescopic rod 14 towards the telescopic cylinder 13 to compress the buffer spring 32. The elastic deformation of the buffer spring 32 absorbs the impact force. It helps reduce the probability of the entire vehicle-mounted camera assembly being damaged by rigid collisions; the entire vehicle-mounted camera actuator, through the coordinated cooperation of the buffer component and the adaptive leveling component, can alleviate to some extent the problem of the vehicle body 1 tilting and the sensing camera body 16 tilting synchronously with the vehicle body when the express delivery vehicle body 1 is driving on long slopes or sloping sections of underground parking garages; it can improve the shortcomings of traditional vehicle-mounted camera equipment that only captures the ground or sky, lacks effective field of view around the vehicle, and reduces the accuracy of environmental recognition, thus improving the efficiency of vehicle surrounding environment perception operations during express delivery vehicle relocation and cargo loading and unloading.

[0036] For details, see Figures 3-4As shown, a fixed top plate 4 is fixedly connected to the top of the telescopic electric cylinder 13. A pressing cone column 41 is fixedly connected to the bottom end of the fixed top plate 4 away from the telescopic electric cylinder 13. A connecting slide column 42 is slidably connected to the top of the fixed rod 2. A retaining ring 43 is fixedly connected to the bottom end of the connecting slide column 42. Return spring columns 44 are slidably connected to both sides of the top of the fixed rod 2. The bottom output ends of a pair of return spring columns 44 are connected to both sides of the top of the retaining ring 43. The top ends of a pair of return spring columns 44 are connected to the outer wall of the connecting slide column 42. A pressing curved plate 45 is fixedly connected to the top of the connecting slide column 42. During operation, when the telescopic electric cylinder 13 drives the fixed rod 2, the sensing camera housing 15, and the sensing camera body 16 to retract during their retraction stroke... The counterweight 27 synchronously drives the sensing camera housing 15 to complete the center of gravity adjustment, and the extrusion plate 45 rotates synchronously with the fixed rod 2. When the entire camera assembly is retracted into the storage slot 2 12, the outer wall of the extrusion plate 45 and the inner wall of the extrusion cone 41 press against each other, pushing the connecting slide column 42 to move downward, so that the retaining ring 43 is embedded in the retaining groove 23. The bottom end of the retaining ring 43 presses and rubs against the outer surface of the sliding ring 24, completing the locking and limiting of the fixed ball 25. This locking structure helps to reduce the random shaking of the sensing camera housing 15 and the sensing camera body 16 inside the storage slot 2 12 when idle, reduces the meaningless reciprocating rotation of the center of gravity adjustment mechanism when not in operation, extends the service life of the entire mechanism, and stabilizes the working performance of the equipment.

[0037] Further, see Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9As shown, a pair of limiting sliding pins 5 are fixedly connected to both sides of the express delivery vehicle body 1. A connecting side plate 51 is slidably connected to the outer wall of the pair of limiting sliding pins 5. A protective side box 52 is fixedly connected to the side wall of the connecting side plate 51. A pair of fixing plates 53 are fixedly connected to the inner side of the protective side box 52 away from the express delivery vehicle body 1. A bevel gear 54 is rotatably connected to the inner side of the pair of fixing plates 53. A threaded screw 55 is fixedly connected to the end of the pair of bevel gears 54 away from the protective side box 52. Threaded cylinders 56 are fixedly connected to both sides of the inner side of the pair of storage slots 12. 6 is threadedly connected to the threaded screw 55. The protective side box 52 has two rotatably connected fixing plates 57 on both sides inside. A pair of fixing plates 57 are fixedly connected to bevel gears 59 at one end close to each other. A connecting plate 58 is fixedly connected to the outer wall of each pair of bevel gears 59. A closed frame 510 is fixedly connected to the end of each pair of connecting plates 58 away from the express delivery vehicle body 1. An elastic connecting plate 511 is fixedly connected to the middle of the closed frame 510. A fixing cylinder 512 is fixedly connected to the inner side of the protective side box 52 away from the express delivery vehicle body 1. The fixing cylinder 512 is connected to the fixing rod 2. For rotational connection, the protective side box 52 is fixedly equipped with elastic sealing covers 513 on both sides of the end near the main body 1 of the delivery vehicle; during operation, the elastic sealing covers 513 and the elastic connecting soft plate 511 are made of elastic and flexible material; when the sensing camera housing 15 and the sensing camera body 16 retract during their retraction stroke, the fixing rod 2 moves synchronously, pulling the protective side box 52 as a whole to move through the fixing cylinder 512; because the threaded cylinder 56 is fixedly installed on the side wall of the storage slot 2 12, when the threaded screw 55 moves synchronously with the protective side box 52, it drives the bevel gear 1 54 to rotate by threaded engagement, and the bevel gear The meshing of the first gear 54 drives the second bevel gear 59 to rotate synchronously. The second bevel gear 59 drives the closed frame 510 to flip and fit against the bottom of the protective side box 52 through the connecting plate 58. After flipping, the elastic connecting plate 511 covers the outside of the counterweight 27, the sensing camera housing 15, and the sensing camera body 16. The elastic connecting plate 511 and the fixed cylinder 512 deform synchronously with the mechanism, which can block some external dust and impurities from entering the storage slot 12, reduce the possibility of impurities adhering to the lens of the sensing camera body 16 and the surface of the entire set of moving components, and help extend the service life of the equipment.

[0038] Among them, see Figure 1 As shown, fixed bases 6 are fixed to both sides of the express delivery vehicle body 1, and air guide plates 61 are fixed to both sides of the bottom of the fixed bases 6. A pair of air guide plates 61 are located on both sides of the protective side box 52. During operation, the fixed bases 6 and the air guide plates 61 cooperate with each other to form a front barrier against mud, sand and debris carried by the airflow, which is beneficial for the long-term operation of the equipment. At the same time, the air guide plates 61 can guide the airflow of the vehicle, appropriately reduce the front wind resistance of the camera storage structure, and improve the stability of the vehicle.

[0039] For details, see Figure 2, Figure 3 As shown, each of the two storage slots 12 has a sliding groove 7 on both sides inside. Each pair of sliding grooves 7 has a fixing ring 71 fixedly connected to one end of each other. Each set of fixing rings 71 has a supporting slide plate 72 slidably connected to its inner side. Each pair of supporting slide plates 72 is connected to the bottom sides of the protective side box 52. During operation, the sliding grooves 7, fixing rings 71 and supporting slide plates 72 cooperate with each other to form a sliding support for the protective side box 52, share the load-bearing pressure of the limiting sliding column 5 and the connecting side plate 51, reduce wear on the sliding parts, and help improve the structural stability of the protective side box 52 during long-term reciprocating movement.

[0040] Further, see Figure 3 As shown, the outer wall of the extrusion curved plate 45 is rotatably connected with a connecting ball 8, and multiple sets of the connecting ball 8 are provided on the outer side of the extrusion curved plate 45. During operation, the multiple sets of connecting balls 8 replace the outer wall of the extrusion curved plate 45 in contact and friction with the inner wall of the extrusion cone 41, reducing the wear caused by direct friction of hard parts and extending the service life of the locking structure.

[0041] Among them, see Figure 5 As shown, the counterweight 27 has a buffer cavity 9 inside. During operation, the buffer cavity 9 is filled with highly elastic buffer material. When the sensing camera housing 15 and the sensing camera body 16 swing back and forth with the counterweight 27, the buffer material inside the buffer cavity 9 absorbs part of the vibration amplitude, which helps to reduce the frequency of image shaking and maintain the relatively clear image captured by the vehicle.

[0042] Among them, see Figure 5 As shown, a protective soft plate 10 is fixed to the outer wall of the counterweight 27. During operation, the protective soft plate 10 is made of a highly wear-resistant and flexible material, which can replace the outer wall of the counterweight 27 in contact and collision with external hard objects, reduce the impact damage to the counterweight 27, and help improve the long-term stable operation of the adaptive leveling mechanism.

[0043] In summary, this effectively solves the problem that in actual operation, when a vehicle is driving on a long slope or an underground parking garage, the vehicle tilts and the camera tilts synchronously with the vehicle, resulting in only ground or sky images being captured. This leads to a significant loss of effective surrounding environment vision, poor environmental perception and recognition, serious interference with vehicle relocation, cargo loading and unloading, and a direct reduction in the overall efficiency of vehicle environmental perception operations.
