It perceives the road environment through the on-board sensor system, and plans the predetermined goals and controls the steering and speed of the vehicle based on the road, vehicle position and obstacle information obtained through perception. The core technical system of unmanned driving technology can be divided into three levels: perception, decision-making and control. In the perception technology, unmanned vehicles need to be equipped with a variety of sensors, such as laser radar, camera, millimeter wave radar, etc., to obtain information about the surrounding environment, including road conditions, the position and speed of other vehicles and pedestrians, etc.

[0004] Due to the driving habits and unskilled driving skills of vehicle drivers, accidents are likely to occur during driving. When the vehicle is collided and the information collection bracket on the vehicle is squeezed, the battery in the bracket will be damaged due to squeezing and deformation, and may even be damaged and self-ignite, thereby damaging the components in the information collection bracket, such as radar probes, cameras, etc., and cannot protect the equipment in the bracket in the event of an accident.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The present invention will be further described below in conjunction with the embodiments.

[0034] Example:

[0035] A metal carrier for unmanned driving information collection and power supply, see attached Figure 1-8 , including a vehicle-mounted radar bracket 1 and a battery bracket 2 connected to each other, the battery bracket 2 is located at the bottom of the vehicle-mounted radar bracket 1 and is connected by fasteners, the vehicle-mounted radar bracket 1 and the battery bracket 2 can be disassembled and separated, and a movable door panel 21 is movably installed at the bottom of the battery bracket 2, and the movable door panels 21 are provided in two groups and are symmetrically distributed. The two groups of movable door panels 21 are rotatably connected to the battery bracket 2 on the sides away from each other, and the movable door panels 21 are used to take out or install the battery when opened, and support the battery at the same time, that is, the movable door panel 21 is used to take out and install the battery when it is opened, and to support the battery when the movable door panel 21 is closed. A support pad is provided in the battery bracket 2 to increase the gap between the battery and the inner wall of the battery bracket 2, thereby improving the heat dissipation effect, and also includes:

[0036] An active ejection component 3 for ejecting the battery in the battery holder 2, the active ejection component 3 limits the opening of the two sets of movable door panels 21 under normal conditions, and when the battery holder 2 is hit and the force reaches a preset value, the two sets of movable door panels 21 at the bottom of the battery holder 2 are actively opened to provide space for the battery to move, and when the battery holder 2 is under pressure, the internal battery will move out, reducing the impact force on the battery, reducing the probability of battery damage and spontaneous combustion after battery damage, and further protecting the information collection parts in the vehicle-mounted radar holder 1, and protecting the whole, the active ejection component 3 includes a rotating rod 31 rotatably set on the top of the vehicle-mounted radar holder 1 and extending into the battery holder 2 and a sliding installed in the battery holder 2 for limiting A push plate 33 is provided to control the movable door panel 21 to be opened, and a limit plate 331 is elastically installed in the push plate 33. The limit plate 331 is used to extend into the movable door panel 21 to limit the movable door panel 21 from rotating on the battery bracket 2 to install the battery. A fixed cylinder 32 is provided at the bottom of the rotating rod 31 to squeeze and extend the limit plate 331. When the rotating rod 31 rotates, the fixed cylinder 32 is driven to change its state to extend and retract the limit plate 331, so that the limit plate 331 is extended into the movable door panel 21 to limit the rotation of the movable door panel 21. When the limit plate 331 is retracted, it is separated from the movable door panel 21. At this time, the movable door panel 21 is rotated and opened on the battery bracket 2. At this time, the battery drops due to gravity and moves out of the battery bracket 2. At this time, even if the battery bracket 2 is deformed, the battery will not be squeezed.

[0037] Specifically, a limit bar is provided on the rotating rod 31, which does not extend into the vehicle-mounted radar bracket 1, and the rotating rod 31 is slidably connected to the fixed cylinder 32 and the gear 41 respectively through the limit bar. The limit bar can limit the relative rotation between the rotating rod 31 and the fixed cylinder 32 and the gear 41, that is, when the gear 41 rotates, the rotating rod 31 is driven to rotate through the limit bar, and the rotating rod 31 drives the fixed cylinder 32 to rotate through the limit bar, so as to cooperate with the push plate 33 to limit and release the restriction on the movable door panel 21.

[0038] Furthermore, the limiting plates 331 are provided with two groups and are symmetrically distributed. The limiting plates 331 are slidably connected to the push plates 33, and the extending directions of the two groups of limiting plates 331 are toward the movable door plate 21. An elastic member 333 is provided between the two groups of limiting plates 331. The elastic member 333 is used to always pull the two groups of limiting plates 331 closer to each other. By setting the elastic member 333, the limiting plates 331 will retract into the push plates 33 and separate from the movable door plate 21 when they are not squeezed.

[0039] Among them, the push plate 33 is provided with a guide rod 332 for guiding the sliding of the limit plate 331, and the elastic member 333 is sleeved on the guide rod 332. The guide rod 332 can prevent the elastic member 333 from deforming and bending, and guide the limit plate 331 at the same time. A cam 321 is provided at the bottom of the fixed cylinder 32. The cam 321 is elliptical, and the cam 321 is located between the two groups of limit plates 331. In the initial state, the two ends of the long radius of the cam 321 abut against the limit plate 331, and the limit plate 331 is squeezed into the movable door panel 21. After the cam 321 rotates, the squeezing of the limit plate 331 is cancelled. At this time, the limit plate 331 retracts and abuts against the two ends of the short radius of the cam 321 under the pull of the elastic member 333.

[0040] In addition, it also includes a guide sleeve 34, which is arranged in the vehicle-mounted radar bracket 1 and sleeved on the rotating rod 31, the rotating rod 31 is located in the guide sleeve 34, and two groups of symmetrically distributed spiral guide grooves 341 are arranged in the guide sleeve 34, the rotating rod 31 is provided with a clearance groove 313, and a push rod 311 is slidably installed in the rotating rod 31, and a lever 312 is provided on the push rod 311, which passes through the clearance groove 313 and extends into the spiral guide groove 341. When the rotating rod 31 rotates, the push rod 311 is driven to rotate by the lever 312. At this time, the lever 312 is guided by the spiral guide groove 341 on the guide sleeve 34. The push rod 311 is in a tensioned state when it is in tension, and the spring in tension can assist in pulling the push plate 33 to support the battery in the battery holder 2. When the push rod 311 is in a tensioned state, the spring can assist in pulling the push plate 33 to support the battery in the battery holder 2. When the push rod 311 is in a tensioned state, the spring can assist in pulling the push plate 33 to support the battery in the battery holder 2. When the push rod 311 is in a tensioned state, the spring can assist in pulling the push plate 33 to support the battery in the battery holder 2.

[0041] In addition, the push plate 33 is connected to the battery bracket 2 through a telescopic rod, and the telescopic rod is detachably connected to the battery bracket 2 and the push plate 33. The telescopic rod is used to guide the push plate 33 to move vertically up and down and limit the rotation of the push plate 33.

[0042] The trigger mechanism includes a gear 41 rotatably mounted on the battery bracket 2 and multiple sets of trigger racks 42. A clockwork spring 22 is provided between the gear 41 and the battery bracket 2. The clockwork spring 22 is used to maintain the angle of the gear 41 in the initial state, while keeping the two ends of the long radius of the cam 321 at the bottom of the fixed cylinder 32 against the limit plate 331. The trigger rack 42 is slidably installed between the vehicle-mounted radar bracket 1 and the battery bracket 2 and extends out. A connecting block is provided between the vehicle-mounted radar bracket 1 and the battery bracket 2, and the trigger rack 42 passes through the connecting block. The trigger rack 42 is meshed and connected with the gear 41. The extended end of the trigger rack 42 can increase the force surface by adding a rectangular block, and is not limited to squeezing the trigger rack 42 at a certain point to drive the gear 41 to rotate.

[0043] It is worth noting that there are four groups of trigger racks 42, and adjacent trigger racks 42 are staggered. The four groups of trigger racks 42 extend to the four sides of the battery bracket 2 respectively. When the four sides of the vehicle-mounted radar bracket 1 and the battery bracket 2 are squeezed, the gear 41 will be rotated to open the movable door panel 21 to release the battery in the battery bracket 2, thereby effectively protecting the battery in the battery bracket 2.

[0044] Working principle: When the vehicle-mounted radar bracket 1 and the battery bracket 2 collide and squeeze during use, and the bottom end of the battery bracket 2 faces the ground, the trigger rack 42 moves and drives the gear 41 to rotate. At this time, the gear 41 drives the rotating rod 31 to rotate. Driven by the upper limit strip of the rotating rod 31, the fixed cylinder 32 rotates and drives the cam 321, so that the two ends of the long radius of the cam 321 are disengaged from the limit plate 331, and the restriction on the limit plate 331 is cancelled. At this time, when the elastic member 333 is reset, the two groups of limit plates 331 are pulled close to each other and retracted into the push plate 33, and the restriction on the movable door plate 21 is cancelled. The battery squeezes the movable door plate 21 due to gravity, and the movable door plate 21 rotates and opens on the battery bracket 2, so that the battery is separated from the battery bracket 2. At this time, even if the battery bracket 2 is squeezed and deformed, it will not press on the battery, which can protect the battery. , and prevent the battery from being damaged and spontaneously combusting to damage information collection parts; when the vehicle-mounted radar bracket 1 and the battery bracket 2 are in an inclined state or the bottom of the battery bracket 2 is not vertically downward, even if the limit plate 331 is retracted into the push plate 33 and the restriction on the movable door plate 21 is cancelled, the movable door plate 21 cannot be opened automatically. At this time, the guide sleeve 34 and the rotating rod 31 arranged in the vehicle-mounted radar bracket 1 cooperate with each other, and when the rotating rod 31 rotates, the push rod 311 and the lever 312 are driven to rotate, and the lever 312 cooperates with the spiral guide groove 341 in the guide sleeve 34, so that the push rod 311 moves in the rotating rod 31 along the setting direction of the give way groove 313, and then pushes the fixed cylinder 32 to move the push plate 33 out. Since a support pad is provided on the outer side of the fixed cylinder 32, the push plate 33 and the support pad will push the movable door plate 21 to open, thereby assisting the removal of the battery in the battery bracket 2.
