Description

Technical Field

[0001] The utility model relates to the technical field of actuators, in particular to an automobile hood opening and closing actuator. Background Art

[0002] The actuator is an essential component of the automatic control system. Its function is to receive the control signal from the controller and change the size of the controlled medium, thereby maintaining the controlled variable at the required value or within a certain range.

[0003] The actuators currently on the market (linked to the car doors) cannot lock the actuator when the actuator is opened and the electric control is locked (locking the car door). In this way, the shell may be closed directly when the cover is closed. Therefore, a block is used to limit the electric lock from entering the locked position during the downward pressure process except for the locking state point. Since the rotating column needs to be pressed down to the locking switching point and then rebound to the locking point, the rotating column has not been pressed down to the locking switching point. At this time, the rotating column has not reached the switching point, and the machine has not reached the locking state. The electric lock pin will be locked in advance at the height of the locking point, which is an abnormal lock. At this time, the cover is not completely closed, and the user may slap the cover without knowing it, causing damage to the actuator and breakage of the electric lock pin. Utility Model Content

[0004] The purpose of the present utility model is to provide an automobile hood opening and closing actuator to solve the problems raised by the above-mentioned background technology.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A lower shell, an upper shell is provided above the lower shell, a solenoid valve is provided in the lower shell, a solenoid valve locking rod is provided on one side of the solenoid valve, and the solenoid valve controls the solenoid valve locking rod to slide horizontally;

[0008] A rotating column, wherein the rotating column is arranged between the upper shell and the lower shell, one end of the rotating column passes through the upper shell, a spring is provided inside the rotating column, two ends of the spring are respectively fixedly connected to the inner wall of the rotating column and the inner wall of the lower shell, the rotating column passes into the interior of the lower shell, the rotating column is slidably connected to the upper shell and the lower shell, and the end portion of the rotating column located inside the upper shell abuts against the lock rod of the solenoid valve;

[0011] The main guide connecting post at the other end of the connecting rod is set to be pressed down from the initial position of the unlocked state to the locking switching point. At this time, the downward pressure distance of the rotating column is the minimum downward pressure value to unlock. At this time, the value between the bottom surface of the rotating column and the rotating column limiting surface at the bottom of the lower shell is A. The main guide connecting post at the other end of the connecting rod is set to be pressed down from the locked state to the unlocking switching point. At this time, the downward pressure distance of the rotating column is the minimum downward pressure value to unlock. At this time, the value between the bottom surface of the rotating column and the rotating column limiting surface at the bottom of the lower shell is B. B The value is less than the A value by a certain amount, and the solenoid valve locking rod advances to the locked position when the rotary column is still in the open state. When the rotary column reaches the A value, it does not contact the solenoid valve locking rod and can reach the locking switching point. The rotary column can enter the locked state. When entering the locked state and wanting to be unlocked, the rotary column needs to be pressed down to reach the B value. Since the solenoid valve locking rod is against the bottom of the rotary column, the rotary column cannot reach the B value and cannot be unlocked. The actuator is locked, and the solenoid valve needs to be unlocked to open the rotary column so that the solenoid valve locking rod can retreat.

[0012] Furthermore, a manual pull wire is provided on the side of the solenoid valve away from the solenoid valve locking rod, and the manual pull wire can control the solenoid valve locking rod to move backward. A guide deceleration block is installed on the solenoid valve locking rod, and the guide deceleration block reduces the noise generated by the solenoid valve.

[0013] Furthermore, a micro switch is installed in the upper shell, and the micro switch is arranged on one side of the rotating column. The micro switch identifies the opening and closing status of the actuator. The rotating column is located on the side wall of the outer side of the upper shell and is provided with a waterproof soft rubber sleeve. The waterproof soft rubber sleeve prevents external water and dust from entering the actuator during the sliding and rotating process of the rotating column.

[0014] Furthermore, a sub-control block is provided on the front side of the main control block, the main control block and the sub-control block are connected and arranged opposite to each other, one end of the connecting rod is located in the main control block and the sub-control block, and the two sides of this end of the connecting rod are respectively fixedly connected to the main guide connecting column and the sub-guide connecting column, and the main guide connecting column and the sub-guide connecting column are respectively arranged in the channels of the main control block and the sub-control block for sliding fit.

[0015] Furthermore, the main control block is provided with the first locking channel and the first unlocking channel, and the first locking channel has multiple locking guide edges, namely the first locking guide edge, the second locking guide edge and the third locking guide edge, to ensure the order of the main guide connecting column passing through the first locking channel to reach the locking point, and the first unlocking channel has multiple unlocking guide edges, namely the first unlocking guide edge, the second unlocking guide edge and the third unlocking guide edge, to ensure the order of the main guide connecting column passing through the first unlocking channel to reach the unlocking point, and finally return to the first return channel, and the first locking channel is provided with the locking switching check step, and the locking switching check step prevents the main guide connecting column from returning to the first locking channel after going down the step, thereby switching to the first locking point, and also serves to emit a locking prompt sound.

[0016] Furthermore, the main control block is provided with the first locking point, and the auxiliary control block and the corresponding part of the main control block are provided with a second locking point. The first locking point and the second locking point are subjected to force synchronously when locking the main guide connecting column and the auxiliary guide connecting column, and an unlocking check step is provided in the first unlocking channel. The unlocking check step plays a prompt sound when unlocking, and the auxiliary control block is provided with a second locking channel, a second unlocking channel and a second return channel corresponding to the position of the main control block.

Connecting columns are fixedly connected to the U-shaped inner walls of the connecting rod, and the connecting columns are stuck in the sliding grooves and are rotatably connected to the sliding grooves.

[0018] Furthermore, a rotating column guide groove is provided on the side of the rotating column, and a rotating column guide column is fixedly connected to the inner wall of the upper shell close to the rotating column. The rotating column guide groove cooperates with the rotating column guide column to rotate, and the rotating column is driven to rotate as the rotating column slides up and down. A card is provided at the upper end of the rotating column, and the different rotation positions of the card lock and unlock the corresponding cover body.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The utility model is that when the rotating column is pressed down to the minimum displacement of the locking point, the distance A between the rotating column and the limit surface is reached. When the rotating column is pressed down to the minimum displacement of the unlocking point, the distance B between the rotating column and the limit point is reached. The B value is less than the A value by a certain amount. When the electric control lock pin advances to the locked state while the rotating column is still in the open state, the rotating column does not contact the lock pin when it reaches the A value, and the lock switching point can be reached. The cover body can enter the locked state. When entering the locked state and wanting to be unlocked, the rotating column needs to be pressed down to the B value. Since the electromagnetic valve lock rod is against the bottom of the rotating column, the rotating column cannot reach the B value and there is no solution. The actuator is locked. If the cover needs to be opened, it only needs to be electrically unlocked to let the electromagnetic lock pin retreat, avoiding abnormal locking and causing damage to the actuator.

[0021] 2. When the actuator is in the open state, the connecting rod presses the micro switch, and the micro switch is turned on. When the actuator is in the locked state, the connecting rod disengages the micro switch, and the micro switch is turned off. That is, the micro switch can send a signal when the actuator is in the open or locked state, so that the information of whether the cover is locked can be obtained in time;

[0022] 3. After opening the charging port cover and plugging in the charging gun for charging, the person needs to close the car door when leaving. After charging is completed, unplug the charging gun and close the charging port cover directly. At this time, the charging port cover and the car door are synchronously locked and there is no need to lock the car door again. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0034] See also Figures 1 to 9 The utility model provides a technical solution: an automobile hood opening and closing actuator, comprising a lower shell 2, an upper shell 3 is arranged above the lower shell 2, a solenoid valve 1 is arranged in the lower shell 2, a solenoid valve lock rod 11 is arranged on one side of the solenoid valve 1, and the solenoid valve 1 controls the solenoid valve lock rod 11 to slide horizontally;

[0035] The structure of the solenoid valve 1 is used to perform locking and unlocking operations between the lower shell 2 and the upper shell 3 .

[0036] A rotating column 7 is provided between the upper shell 3 and the lower shell 2. One end of the rotating column 7 passes through the upper shell 3. A spring 73 is provided inside the rotating column 7. The two ends of the spring 73 are fixedly connected to the inner wall of the rotating column 7 and the inner wall of the lower shell 2 respectively. The rotating column 7 passes into the interior of the lower shell 2. The rotating column 7 is slidably connected to the upper shell 3 and the lower shell 2. The inner end of the rotating column 7 located in the upper shell 3 abuts against the solenoid valve lock rod 11.

[0037] When the rotating column 7 is unlocked, the actuator is opened by the elastic force of the spring 73. After the solenoid valve locking rod 11 is extended, the solenoid valve locking rod 11 abuts against the bottom of the rotating column 7 to avoid abnormal locking.

[0038] The main control block 4 is arranged in the upper shell 3 and the lower shell 2. The main control block 4 is arranged on the side of the solenoid valve 1 away from the rotating column 7. The main control block 4 is provided with a first locking channel 42, a first unlocking channel 43, a first return channel 47, an unlocking guide cutting edge 41, a locking guide cutting edge, a first locking point 44, an unlocking check step 48 and a locking switching check step 45.

[0039] The connecting rod 6 is arranged between the main control block 4 and the rotating column 7. A rotating shaft 62 is provided in the middle of the connecting rod 6. The connecting rod 6 is rotatably mounted between the upper shell 3 and the lower shell 2 via the rotating shaft 62. One end of the rotating shaft 62 is connected to the rotating column 7 via a rotating column connecting column 63. The other end of the connecting rod 6 is connected to the main control block 4 via a main guide connecting column 61. At the same time, it is slidably connected to the main control block 4 and the rotating column 7. The up and down sliding of the rotating column 7 drives the connecting rod 6 to swing in a seesaw-like manner with the rotating shaft 62 as the central axis.

[0040] Through several channels, locking points and unlocking points in the main control block 4, the main guide connecting column 61 on the connecting rod 6 controls the unlocking and locking of the rotating column 7 when entering the locking point and unlocking point through different channels respectively, so as to realize the opening and locking of the actuator.

[0041] The main guide connecting post 61 at the other end of the connecting rod 6 is set to be pressed down from the initial position of the unlocked state to reach the locking switching point, that is, the pressing distance of the rotating column 7 is the minimum pressing value until the lock is locked. At this time, the value between the bottom surface of the rotating column 7 and the rotating column limiting surface 21 at the bottom of the lower shell 2 is A. The main guide connecting post 61 at the other end of the connecting rod 6 is set to be pressed down from the locked state to reach the unlocking switching point, that is, the pressing distance of the rotating column 7 is the minimum pressing value for unlocking. At this time, the value between the bottom surface of the rotating column 7 and the rotating column limiting surface 21 at the bottom of the lower shell 2 is B, the B value is less than the A value by a certain amount, and the solenoid valve locking rod 11 advances to the locked position when the rotating column 7 is still in the open state. When the rotating column 7 reaches the A value, it does not contact the solenoid valve locking rod 11 and can reach the locking switching point. The rotating column 7 can enter the locked state. When entering the locked state to be unlocked, the rotating column 7 needs to be pressed down to reach the B value. Since the solenoid valve locking rod 11 is against the bottom of the rotating column 7, the rotating column 7 cannot reach the B value and cannot be unlocked. The actuator is locked, and the solenoid valve 1 needs to be unlocked to open the rotating column 7 to allow the solenoid valve locking rod 11 to retreat.

[0042] A manual pull wire 9 is provided on the side of the solenoid valve 1 away from the solenoid valve locking rod 11, and the manual pull wire 9 can control the solenoid valve locking rod 11 to retreat. A guide deceleration block 8 is installed on the solenoid valve locking rod 11, and the guide deceleration block 8 reduces the noise generated by the solenoid valve 1.

[0043] The manual pull wire 9 is used for manual unlocking when the electromagnetic valve lock rod 11 has a problem, and the guide speed reduction block 8 is used to reduce the noise generated when the electromagnetic valve 1 is in use.

[0044] A micro switch 10 is installed in the upper shell 3. The micro switch 10 is arranged on one side of the rotating column 7. The micro switch 10 identifies the opening and closing status of the actuator. The rotating column 7 is located on the side wall outside the upper shell 3 and is provided with a waterproof soft rubber sleeve 71. The waterproof soft rubber sleeve 71 prevents external water and dust from entering the actuator during the sliding and rotating process of the rotating column 7.

[0045] The micro switch 10 can identify the opening and closing status of the actuator. When the actuator is in the open state, the connecting rod 6 presses the micro switch 10, and the micro switch is turned on. When the actuator is in the locked state, the connecting rod 6 disengages from the micro switch 10, and the micro switch 10 is disconnected. That is, the micro switch 10 can send a signal when the actuator is in the open or locked state. The waterproof soft rubber sleeve 71 prevents external water and dust from entering the actuator during the up and down movement of the rotating column 7.

[0046] A secondary control block 5 is provided on the front side of the main control block 4. The main control block 4 and the secondary control block 5 are connected and arranged opposite to each other. One end of the connecting rod 6 is located in the main control block 4 and the secondary control block 5. The two sides of this end of the connecting rod 6 are respectively fixedly connected to the main guide connecting column 61 and the secondary guide connecting column 64. The main guide connecting column 61 and the secondary guide connecting column 64 are respectively arranged in the channels of the main control block 4 and the secondary control block 5 for sliding cooperation.

[0047] The main control block 4 is provided with the first locking channel 42 and the first unlocking channel 43. The first locking channel 42 is provided with a plurality of locking guide edges 46, namely a first locking guide edge 461, a second locking guide edge 462 and a third locking guide edge 463, to ensure that the main guide connecting column 61 reaches the locking point in order when passing through the first locking channel 42. The first unlocking channel 43 is provided with a plurality of unlocking guide edges 41, namely a first unlocking guide edge 411, a second unlocking guide edge 412 and a third unlocking guide edge 413, to ensure that the main guide connecting column 61 reaches the unlocking point in order when passing through the first unlocking channel 43 and finally returns to the first homing channel 47. The first locking channel 42 is provided with the locking switching check step 45. The locking switching check step 45 prevents the main guide connecting column 61 from returning to the first locking channel 42 after descending the step, thereby switching to the first locking point 44, and also serves to emit a locking prompt sound.

[0048] The main control block 4 is provided with the first locking point 44, and the auxiliary control block 5 and the corresponding part of the main control block 4 are provided with the second locking point 52. The first locking point 44 and the second locking point 52 are synchronously subjected to force when locking the main guide connecting column 61 and the auxiliary guide connecting column 64, and an unlocking check step 48 is provided in the first unlocking channel 43. The unlocking check step 48 plays a prompt sound when unlocking. The auxiliary control block 5 is provided with a second locking channel 51, a second unlocking channel 53 and a second return channel 54 corresponding to the position of the main control block 4.

[0049] The main guide connecting column 61 moves in the channel of the main control block 4, and the auxiliary guide connecting column 64 moves in the channel of the auxiliary control block 5. The channels in the main control block 4 and the auxiliary control block 5 correspond one to one, so that the column guide connecting column 61 and the auxiliary guide connecting column 64 are locked and unlocked synchronously, so that the connecting rod 6 is evenly stressed during the swinging process.

[0050] One end of the connecting rod 6 arranged on the rotating column 7 is set to be U-shaped, and the outer walls on both sides of the rotating column 7 are provided with symmetrical sliding grooves. The U-shaped inner walls of the connecting rod 6 are respectively fixedly connected with rotating column connecting columns 63, and the rotating column connecting columns 63 are stuck in the sliding grooves and are rotatably connected to the sliding grooves.

[0051] The rotating column 7 will rotate during the pressing process. Through the rotating structure of the rotating column connecting column 63 and the sliding groove, the connecting rod 6 and the rotating column 7 can rotate, that is, the rotation of the rotating column 7 will not affect the swing of the connecting rod 6.

[0052] A rotation column guide groove 72 is provided on the side of the rotation column 7, and a rotation column guide column 31 is fixedly connected to the inner wall of the upper shell 3 close to the rotation column 7. The rotation column guide groove 72 cooperates with the rotation column guide column 31 to rotate, and the rotation column 7 is driven to rotate as the rotation column 7 slides up and down. A card is provided at the upper end of the rotation column 7, and the different rotation positions of the card lock and unlock the corresponding cover body.

[0053] Through the cooperation between the rotating column guide groove 72 and the rotating column guide column 31 , when the rotating column 7 is pressed in the upper shell 3 , it rotates toward the interior of the upper shell 3 and the lower shell 2 .
