[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0031] The purpose of the present invention is to provide a driving mode switching mechanism and a vehicle to solve the problems existing in the above-mentioned prior art and to achieve driving mode switching through a simpler mechanical structure.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Embodiment 1

[0034] This embodiment provides a driving mode switching mechanism, such as Figure 1-7 As shown, it includes: a support structure 1, a pedal 2, a connecting component 3, a throttle controller 4, a first switching rod 5, a second switching rod 6, a switching component 7 and a control component 8, the pedal 2 is rotatably connected to the support structure 1, the throttle controller 4 and the control component 8 are both fixedly connected to the support structure 1, one end of the connecting component 3 is fixedly connected to the pedal 2, and the other end is connected to the input end of the throttle controller 4, and the output end of the throttle controller 4 is used to connect to the input end of the vehicle power system; the first end of the first switching rod 5 is rotatably connected to the support structure 1 around the first rotating shaft 62, and the other end is connected to the connecting component 3, the control component 8 has a free end, one end of the second switching rod 6 is coaxially rotatably connected to the support structure 1 with the first end of the first switching rod 5, and the other end is connected to the control component The free end of the control component 8 is connected, and the control component 8 and the switching component 7 are both used for signal connection with the control system of the vehicle; the switching component 7 is constructed to prevent the first switching rod 5 from rotating relative to the second switching rod 6 to enter the automatic driving mode, or to enable the first switching rod 5 to rotate relative to the second switching rod 6 to enter the manual driving mode; in the automatic driving mode, the free end of the control component 8 can drive the first switching rod 5 and the second switching rod 6 to rotate synchronously around the first rotating shaft 62 and enable the connecting component 3 to drive the input end of the throttle controller 4 to rotate. In the manual driving mode, the pedal 2 can rotate and enable the connecting component 3 to drive the input end of the throttle controller 4 to rotate, and the throttle controller 4 can control the vehicle power system to operate with different output powers according to the rotation angle of the input end of the throttle controller 4.

[0035] The driving mode switching mechanism provided in this embodiment can change the connection mode between the second switching rod 6 and the first switching rod 5 through the switching component 7. Under the action of the switching component 7, when the first switching rod 5 cannot rotate relative to the second switching rod 6 around the first rotating shaft 62, the driving mode switching mechanism enters the automatic driving mode. At this time, the free end of the control component 8 can move under the control of the vehicle control system and make the first switching rod 5 and the second switching rod 6 rotate synchronously around the first rotating shaft 62. When the first switching rod 5 and the second switching rod 6 rotate, the connecting component 3 can be deflected and drive the input end of the throttle controller 4 to rotate, and the throttle controller 4 can drive the vehicle. The control system realizes the automatic driving of the vehicle with different power outputs; when the switching component 7 controls the first switching rod 5 to rotate relative to the second switching rod 6 around the first rotating shaft 62, the driving mode switching mechanism enters the manual driving mode. At this time, when the free end of the control component 8 moves, the second switching rod 6 will rotate relative to the first switching rod 5 and cannot drive the first switching rod 5 to move. The driver can step on the pedal 2, and the rotation of the pedal 2 controls the deflection of the connecting component 3. The connecting component 3 can drive the input end of the throttle controller 4 to rotate, and the throttle controller 4 can control the power system of the vehicle to output different powers, thereby manually changing the speed of the vehicle. The driving mode switching mechanism changes the connection relationship between the first switching rod 5 and the second switching rod 6 by the switching component 7, thereby realizing the convenient switching of the driving mode.

[0036] In one implementation of the present embodiment, the connecting assembly 3 includes an active push rod 31, a driven push rod 32, a pin 33 and a slider 34. One end of the active push rod 31 is fixedly connected to the pedal 2, and the other end forms a rotational connection with one end of the driven push rod 32 around the pin 33. The end of the driven push rod 32 away from the pin 33 is fixedly connected to the input end of the throttle controller 4, the pin 33 is fixedly connected to the slider 34, and the slider 34 is slidably connected to the first switching rod 5 along the length direction of the first switching rod 5. In manual driving mode, pedal 2 is depressed to rotate pedal 2, which drives active push rod 31 to deflect, active push rod 31 drives driven push rod 32 to deflect, and driven push rod 32 drives the input end of throttle controller 4 to rotate, so as to change the speed of the vehicle. Moreover, driven push rod 32 drives slider 34 to slide on first switching rod 5, and drives the first switching rod 5 to rotate at the same time, so that the first switching rod 5 will not affect the movement of driven push rod 32. In automatic driving mode, the free end of control component 8 makes the first switching rod 5 and the second switching rod 6 rotate synchronously, the first switching rod 5 drives slider 34 to rotate (at this time, slider 34 will also slide on the first switching rod 5) and deflects driven push rod 32, so that driven push rod 32 can drive the input shaft of throttle controller 4 to rotate and change the speed of the vehicle.

[0037] In one implementation of the present embodiment, the switching assembly 7 includes a first driver 71 and a locking rod 72. A first locking hole 51 is provided on the first switching rod 5, and a second locking hole 61 is provided on the second switching rod 6. The positions of the first locking hole 51 and the second locking hole 61 can correspond to each other. The first driver 71 is connected to the second switching rod 6, and the locking rod 72 is fixedly connected to the output end of the first driver 71. The locking rod 72 can be simultaneously extended into the first locking hole 51 and the second locking hole 61 or separated from the first locking hole 51 under the drive of the first driver 71. When it is necessary to switch from manual mode to automatic driving mode, the driver releases the accelerator, and the first driver 71 drives the locking rod 72 to extend into the first locking hole 51 and the second locking hole 61 at the same time, so that the first switching rod 5 cannot rotate relative to the second switching rod 6. At this time, the control component 8 can control the vehicle speed by moving the free end; when the automatic driving is switched to manual driving, (in order to prevent a sudden drop in speed, the driver can use his foot to support the pedal 2 to keep the pedal 2 at an angle), the first driver 71 drives the locking rod 72 to separate from the first locking hole 51, so that the first switching rod 5 can rotate relative to the second switching rod 6. At this time, the driver can control the speed of the vehicle by controlling the rotation angle of the pedal 2. By setting the first driver 71, the locking rod 72, the first locking hole 51 and the second locking hole 61, a smooth switch is achieved when the vehicle automatic driving is switched to manual driving. As long as the operation is correct, the passengers in the car will not feel the abrupt drop in speed, which improves the comfort of the passengers.

[0038] It should be noted that in addition to the first driver 71, the locking rod 72, the first locking hole 51 and the second locking hole 61, other devices can also be used to change the connection relationship between the first switching rod 5 and the second switching rod 6. For example, a clamp can be fixedly connected to the second switching rod 6. When the automatic mode is switched to the manual driving mode, the clamp is loosened. When the manual driving mode is switched to the automatic driving mode, the clamp is used to clamp the first switching rod 5. Electromagnets can also be respectively arranged on the first switching rod 5 and the second switching rod 6. When the automatic driving mode is switched to the manual driving mode, the magnets are powered off. When the manual driving mode is switched to the automatic driving mode, the magnets are powered on and adsorbed together.

[0039] In one implementation of the present embodiment, when the locking rod 72 is separated from the first locking hole 51, the locking rod 72 is located in the second locking hole 61; the switching assembly 7 also includes a screw 73, a nut 74 and a connecting piece 75, the screw 73 is rotatably connected to the first switching rod 5, the screw 73 is parallel to the locking rod 72, the nut 74 is threadedly connected to the screw 73, the connecting piece 75 is fixedly connected to the nut 74, and the first driver 71 is fixedly connected to the connecting piece 75. When the electronic device fails due to a fault in the automatic driving mode, the driver can manually rotate the screw 73. At this time, since the locking rod 72 is located in the first locking hole 51 and the second locking hole 61, the rotation of the screw 73 will cause the nut 74 to rotate along the thread. By controlling the direction of rotation of the screw 73, the nut 74 is rotated along the thread in the direction away from the second switching rod 6, so that the connecting seat can drive the first driver 71 away from the second switching rod 6 in a straight line, thereby separating the locking rod 72 from the first locking hole 51 and switching to the manual driving mode, so that the driver can manually control the vehicle speed, preventing accidents caused by the failure of the electronic device due to a fault, and improving safety. Among them, the end of the screw 73 away from the second switching rod 6 is fixedly connected with a handle 731 to facilitate the driver to manually operate the screw 73 to rotate.

[0040] In one embodiment of the present embodiment, the driving mode switching mechanism provided in the present embodiment further includes an arc rod 52, one end of which is fixedly connected to the first switching rod 5, and a limiting groove is provided on the arc rod 52, one end of which corresponds to the position of the first locking hole 51, and the limiting groove extends along a circle with the intersection of the central axis of the first rotating shaft 62 and the first switching rod 5 as the center. In the manual driving mode, the locking rod 72 can be rotated into the limiting groove and move along the limiting groove. In the manual driving mode, the first switching rod 5 rotates relative to the second switching rod 6. If the driver controls the locking rod 72 to extend when the pedal 2 is not released, the locking rod 72 will be against the arc groove and cannot be extended (if the arc plate is not provided, the locking rod 72 will be stuck to the first switching rod 5 when the driver controls the locking rod 72 to extend when the pedal 2 is not released). In order to prevent the end of the locking rod 72 extending out of the first locking hole 51 from colliding with the first switching rod 5, the end of the locking rod 72 can enter the arc groove.

[0041] In one embodiment of the present embodiment, the control assembly 8 includes a second driver 81, a connecting rod 82 and a sliding rod 83. The second driver 81 is fixedly connected to the support structure 1. One end of the connecting rod 82 is fixedly connected to the output end of the second driver 81, and the other end is fixedly connected to one end of the sliding rod 83. The connecting rod 82 is perpendicular to the first rotating shaft 62, and the sliding rod 83 is perpendicular to the connecting rod 82. The cross section of the sliding rod 83 along the direction perpendicular to its own axis is circular. The second switching rod 6 is provided with a slide groove 63 extending along the length direction of the second switching rod 6. The sliding rod 83 is arranged in the slide groove 63, and the inner side surface of the slide groove 63 contacts the two sides of the sliding rod 83. The second driver 81 can drive the connecting rod 82 to move in a straight line and make the sliding rod 83 move in a straight line. In the automatic driving mode, the second driver 81 controls the distance of the sliding rod 83 to move in a straight line under the control of the vehicle control system. The sliding rod 83 can control the rotation angle of the second switching rod 6 and the first switching rod 5 by applying a force to the inner side wall of the slide groove 63. It should be noted that when the slide bar 83 moves linearly, there is both sliding along the slide groove 63 and relative rotation between the slide bar 83 and the slide groove 63 .

[0042] Specifically, the second driver 81 and the first driver 71 are both electrically driven linear modules, and the interior of the modules can be configured in various forms such as a lead screw nut 74 mechanism, a cylinder, a hydraulic cylinder, etc.

[0043] In one implementation of this embodiment, the driving mode switching mechanism provided in this embodiment further includes a dust removal device 9, which is fixedly connected to the support structure 1 and has an air outlet 922, which can spray air toward the first switching rod 5 and / or the second switching rod 6. The dust removal device 9 can remove dirt and dust on the first switching rod 5 and / or the second switching rod 6, so that the sliding block 34 and the sliding rod 83 can slide more smoothly.

[0044] In one embodiment of the present embodiment, the dust removal device 9 includes an air storage box 91, an exhaust pipe 92 and a nozzle 921. The air storage box 91 is fixedly connected to the support structure 1. One end of the exhaust pipe 92 is connected and communicated with the air storage box 91, and the other end is connected and communicated with one end of the nozzle 921. The other end of the nozzle 921 is blocked. A plurality of air outlets 922 are provided on the side of the nozzle 921, and each air outlet 922 faces the first switching rod 5 and / or the second switching rod 6. By providing a plurality of air outlets 922 on the side of the nozzle 921, the gas can be sprayed onto the first switching rod 5 and / or the second switching rod 6 more evenly. Among them, each air outlet 922 of the nozzle 921 is preferably facing the first switching rod 5.

[0045] In one embodiment of the present embodiment, the dust removal device 9 also includes a support plate 94, an air supply tank 93, a piston 95, a support rod 96, a support member 97, an air inlet pipe 981, an air outlet pipe 982 and an elastic member 99. The support plate 94 is fixedly connected to the support structure 1, the air supply tank 93 is fixedly connected to the support plate 94, the piston 95 can be movably arranged in the piston 95, the outer side surface of the piston 95 contacts the inner side surface of the air supply tank 93, and the piston 95 divides the air supply tank 93 into a first cavity 931 and a second cavity 932. The support rod 96 is arranged in the first cavity 931, one end of the support rod 96 is fixedly connected to the piston 95, and the other end extends out of the air supply tank 93 and is fixedly connected to the support member 97. The elastic member 99 is fixedly connected in the second cavity 932, one end of the elastic member 99 abuts against the piston 95, and the other end abuts against the On the inner wall, one end of the air inlet pipe 981 is connected to the second cavity 932, and the other end is connected to the outside world. An air inlet check valve is arranged in the air inlet pipe 981, and the positive flow direction of the air inlet check valve is from the outside world to the air supply tank 93. One end of the air outlet pipe 982 is connected to the second cavity 932, and the other end is connected to the air storage box 91. An air outlet check valve is arranged in the air outlet pipe 982, and the positive flow direction of the air outlet check valve is from the air supply tank 93 to the air storage box 91. The position of the support member 97 corresponds to the position of the driven push rod 32. When the driven push rod 32 is deflected, it can press the support member 97 and make the support rod 96 drive the piston 95 to move in the air supply tank 93 to reduce the volume of the second cavity 932. The piston 95 can also move in the air supply tank 93 under the rebound action of the elastic member 99 to reduce the volume of the first cavity 931. A pressure relief valve is arranged in the exhaust pipe 92. When the driven push rod 32 is deflected in both automatic and manual modes, and when the driven push rod 32 is deflected and presses the support member 97, the support member 97 drives the support rod 96 and the piston 95 to move, thereby reducing the size of the second cavity 932. At this time, the gas in the second cavity 932 enters the air storage box 91 (the air intake check valve prevents the gas from being discharged from the air intake pipe 981). When the driven push rod 32 is deflected again and the pressure on the support member 97 is released, the piston 95 can move under the elastic force of the elastic member 99 and expand the size of the second cavity 932. At this time, the gas is sucked into the second cavity 932 (the air outlet check valve prevents the gas in the air storage box 91 from entering the air supply tank 93). With the multiple reciprocating deflections of the driven push rod 32, the amount of gas stored in the air storage box 91 reaches the threshold of the pressure relief valve, and the gas can be discharged from the nozzle 921 and sprayed toward the first switching rod 5 and / or the second switching rod 6. By providing an air supply tank 93, a piston 95, a support rod 96, a support member 97, an air inlet pipe 981, an air outlet pipe 982 and a pressure relief valve, automatic air supply and automatic dust removal of the air storage box 91 are achieved during vehicle driving without the need to provide other electronic equipment, thus saving energy, having a reliable structure and making the overall operation more stable.

[0046] Specifically, a slot is provided on the support member 97, and the driven push rod 32 is disposed in the slot.
