Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a switch actuator. Background Art

[0002] The car refueling / charging port switch actuator is a control device specially used to control the opening and closing of the car refueling / charging port cover;

[0003] like Figure 1 The invention is composed of a lock head and a lock body that are rotated and extended. A tilting piece and a lock plate are arranged in the lock body. The tilting piece and the lock plate cooperate to lock the lock head at the highest limit position and the lowest limit position. A lock hole that cooperates with the lock head is arranged on the cover door. When the lock head is at the lowest limit position, the cover door is locked. When the lock head is at the highest limit position, the cover door is separated from the cover door.

[0004] In reality, the switch actuator on the vehicle body is often not used for the expected service life, and the lock will not be sensitive when locked in the lowest limit position. In addition, when the vehicle body shakes over bumpy roads while driving, the lock can easily pop out, causing the cover door to be bounced open. Research has found that the reason is that when the lock is locked in the lowest position by the tilting piece, it is not in a fixed state. During use, the vehicle body vibrates, causing vibration and wear between the tilting piece and the lock plate. After a long time, the lock plate is not tightly locked to the tilting piece, causing the lock to be insensitive and easy to pop out. Summary of the invention

[0034] 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.

[0035] In order to further understand the content of the present invention, the present invention is described in detail in conjunction with the accompanying drawings.

[0036] The switch actuator on the vehicle body has not been used for the expected service life, and the lock head is not sensitive when locked at the lowest limit position. In addition, when the vehicle travels over a bumpy road, the vibration causes the lock head to pop out and the cover door is bounced open. The reason is that when the lock head is locked at the lowest position by the tilting member body 15, it is not in a fixed state. This causes the vehicle to vibrate during use, resulting in vibration wear between the tilting member body 15 and the lock plate body 16. Specifically, Figure 2As shown, a slideway is provided on the surface of the lock plate body 16. When one end of the lift body 15 is located at position b, the lock head is at the highest position. In this state, the lock head and the cover door are separated; when one end of the lift body 15 is located at position a, the lock head is at the lowest position. In this state, the lock head locks the cover door. The lift body 15 has elastic potential energy from a to b. When opening the cover door daily, the cover door is first pressed to cause one end of the lift body 15 to move upward from position a, and is guided by the upper guide groove to the left slideway and slide into position b; When one end of the body 15 is located at a to lock the cover door normally, it is precisely because one end of the lift body 15 has space to move upward at a that causes the vehicle body to vibrate and shake strongly when encountering bumpy roads during driving, causing the cover door to shake, and the shaking is transmitted to the lift body 15 through the lock head, causing one end of the lift body 15 to wear against the lock plate body 16 at a, causing multiple limiting edges and corners of a to be worn, ultimately resulting in a poor limiting effect, and ultimately resulting in a poor locking effect of the switch actuator and insensitive locking.

[0037] Combination Figure 1-Figure 12 A switch actuator comprises an actuator body 10, wherein the actuator body 10 comprises a lock body and a lock head that rotates and extends outward, wherein a tilting member body 15 for prying the lock head and a lock plate body 16 for limiting the swing of the tilting member body 15 are arranged in the lock body, and a locking mechanism 20 for locking the tilting member body 15 when it swings is also arranged in the lock body;

[0038] A damping ring 153 is fixedly connected to one side of the rotating rod 151 of the tilting member body 15;

[0039] The locking mechanism 20 includes a swinging assembly 21, a pushing assembly 22, and a pressing assembly 23. The pressing assembly 23 is arranged on one side of the damping ring 153, and is movable to lock the damping ring 153 and delay the release. The swinging assembly 21 is assembled on the outer side of the lock body through the pushing assembly 22, and generates mechanical energy as the lock body shakes. The pushing assembly 22 is also connected to the pressing assembly 23. The pushing assembly 22 generates mechanical energy through the swinging assembly 21 as the lock body shakes to drive the pressing assembly 23 to lock the damping ring 153. The pressing assembly 23 delays the release, so that the lock body continues to shake, and the tilting member body 15 is continuously limited to swing, so as to reduce unnecessary wear between the tilting member body 15 and the lock plate body 16.

[0040] When the vehicle is driving and encounters a bumpy road surface that may cause vibration and wear between the tilting piece body 15 and the lock plate body 16, the swing component 21 detects the vibration of the lock body along with the vehicle body, and can also automatically generate mechanical energy to trigger the pressure component 23 through the pushing component 22, so that the pressure component 23 can lock the sliding swinging state of the tilting piece body 15 and delay the unlocking. In this way, even if the vehicle is driving on a continuous bumpy road surface, the pressure component 23 can keep the tilting piece body 15 locked, so that the tilting piece body 15 will not be shaken by the shaking cover door when driving over the entire continuous bumpy road surface, thereby ensuring the relative stillness of the tilting piece body 15 and the lock plate body 16, thereby avoiding unnecessary wear between the tilting piece body 15 and the lock plate body 16.

[0041] In the previous embodiment: the swing assembly 21 includes a swing rod 211 that swings up and down on one side of the push assembly 22, and one end of the swing rod 211 is fixedly connected to a counterweight 212. When the lock body is installed on the vehicle body, the end of the swing rod 211 with the counterweight 212 swings up and down toward the ground, so that when the vehicle body is bumpy, the counterweight 212 will shake up and down, prompting the swing rod 211 to swing up and down, thereby prompting the push assembly 22 to generate axis rotation mechanical kinetic energy;

[0042] One side of the counterweight 212 is connected to a positioning spring 213 that elastically supports it. One side of the positioning spring 213 is fixedly assembled on the outer surface of the lock body through a support frame 214. The positioning spring 213 supports the counterweight 212, which facilitates limiting the initial position of the counterweight 212 and facilitating the counterweight 212 to swing up and down more easily.

[0043] In the previous embodiment: the pushing assembly 22 includes a bearing 223 fixedly embedded in the surface of the lock body, the inner ring of the bearing 223 is rotatable, and a rotating rod 221 is installed in the ring, one end of the swing rod 211 is fixedly connected to the side surface of one end of the rotating rod 221, and the other end of the rotating rod 221 is provided with a conversion component for converting the rotation axis movement of the rotating rod 221 into linear movement, and the conversion component drives the pressure assembly 23 to lock the damping ring 153, and by converting the rotation axis movement of the rotating rod 221 into linear movement, the converted linear movement mechanical kinetic energy is more convenient to be used by the pressure assembly 23;

[0044] The conversion component includes an active crown gear 224 fixed to the lower end of the rotating rod 221 and connected coaxially, a driven crown gear 225 cooperating with the active crown gear 224 is provided at the lower side of the active crown gear 224, an extrusion block 226 is fixedly connected to the lower side of the driven crown gear 225, the active crown gear 224 and the driven crown gear 225 are hollow, and a tension spring 227 for pulling the active crown gear 224 and the driven crown gear 225 to keep meshing is provided in the hollow cavity, the rotating rod 221 is also rotated by the axis and penetrated by a fixed rod 222, a fixing frame 2221 is provided at the upper end of the fixed rod 222 to fix it, a limited rotation block 2222 is fixedly connected to the lower end of the fixed rod 222, and a limiting groove 2251 is provided on the inner side of the driven crown gear 225 to slide and engage with the limited rotation block 2222;

[0045] When the fixed rod 222 rotates through the swing of the rocker arm 211, the driven crown gear 225 is restricted in rotation by the limiting block 2222, and the driven crown gear 225 is pulled by the tension spring 227 to maintain contact with the active crown gear 224. This makes the active crown gear 224 rotate relative to the driven crown gear 225, pushing the driven crown gear 225 to move downward. Therefore, during the reciprocating rotation of the rotating rod 221, the driven crown gear 225 reciprocates linearly up and down in the vertical direction, driving the extrusion block 226 to reciprocate up and down.

[0046] In the previous embodiment: the pressure-applying assembly 23 includes a fixedly mounted oil cylinder 231, an oil sac 232 and an oil box 233 are mounted on the upper side of the oil cylinder 231, an arc block 234 is disposed on the lower side of the oil cylinder 231, the arc block 234 is suspended on the upper side of the damping ring 153, the upper surface of the oil sac 232 and the lower surface of the extrusion block 226 are tightly bonded, the closed space inside the oil box 233, the oil sac 232 and the oil cylinder 231 is filled with hydraulic oil, and the extrusion block 226 will cause the oil sac 232 to reciprocate when it moves up and down.

[0047] The first one-way valve 2321 and the second one-way valve 2322 are connected to the two sides of the oil bag 232 respectively. The inside of the oil box 233 is connected to the inside of the oil bag 232 in one direction through the first one-way valve 2321. The oil bag 232 is connected to the inside of the oil cylinder 231 in one direction through the second one-way valve 2322. A third one-way valve 2331 is provided between the oil cylinder 231 and the oil box 233. The third one-way valve 2331 is connected to the inside of the oil box 233 in one direction.

[0048] A piston plate 2311 is provided inside the oil cylinder 231 to move up and down. The lower side of the piston plate 2311 is fixedly connected to the arc block 234 through an extrusion column 2312. A rubber extrusion pad 2341 is provided on the lower side of the arc block 234.

[0049] The oil box 233 is designed to be cylindrical, and an upper and lower movable oil plug is arranged inside it, a plug rod 2332 is fixedly connected to the upper side of the oil plug, and a push spring 2333 for elastically pulling it is also arranged on the upper side of the oil box 233;

[0050] Under the same hydraulic pressure, the liquid flow rate of the third one-way valve 2331 is smaller than that of the first one-way valve 2321 and the second one-way valve 2322, and the liquid flow rates of the first one-way valve 2321 and the second one-way valve 2322 are the same;

[0051] When the squeezing block 226 reciprocates up and down to cause the oil bag 232 to reciprocate and contract, the oil bag 232 will pump the continuous hydraulic oil in the oil box 233 into the oil cylinder 231 and the closed cavity above the piston plate 2311, so that the piston plate 2311 is pushed downward, and the arc block 234 is pushed to the surface of the damping ring 153 through the squeezing column 2312. The rubber squeezing pad 2341 undergoes a certain deformation to press the damping ring 153, so that the rotation of the locking tilting member body 15 is stopped. In addition, since the third one-way valve 2331 is under the same hydraulic pressure, the third one-way valve 2331 is under the same hydraulic pressure. , the liquid passing through the second one-way valve 2322 has a flow rate lower than that of the second one-way valve 2322, which causes the push spring 2333 to push the plug rod 2332, and it takes a certain amount of time to draw the hydraulic oil in the oil cylinder 231 back into the oil box 233 through the third one-way valve 2331. If the vehicle body is always in a bumpy state, the oil bag 232 is continuously in a reciprocating contraction state, and the oil cylinder 231 will maintain high-pressure hydraulic oil, prompting the piston plate 2311 to maintain the state of pushing the arc block 234, and then prompting the arc block 234 to keep pressing the damping ring 153;

[0052] It should be noted that when the piston plate 2311 is at the extreme downward position, and the oil bag 232 is still pushed back and forth by the extrusion block 226 to shrink, there is no need to worry about the problem of the oil cylinder 231 bursting, because as the hydraulic strength of the hydraulic oil in the oil cylinder 231 increases, the flow rate of the hydraulic oil flowing into the oil box 233 through the third one-way valve 2331 will also increase, and finally a dynamic flow balance will be formed;

[0053] In addition, when the vehicle body changes from a dynamic state to a static state, such as when the vehicle drives into a gas station for refueling, when the vehicle body is static, the push spring 2333 elastically pulls the second one-way valve 2322 through the third one-way valve 2331 to draw back the hydraulic oil in the cylinder 231, so that the piston plate 2311 returns to its position. The time is designed accordingly, and the preferred time is between 15 seconds and 20 seconds. In this way, the vehicle body quickly changes from a dynamic state to a static state, and the arc block 234 can release the restriction on the lift body 15 within the corresponding time, so that the cover door can be smoothly opened.

[0054] Furthermore, the lock body includes an upper shell 11 and a lower cover plate 12, the lock head includes a rotating cylinder 14 and a clamping block 13 fixedly connected to the upper end, one end of the lift body 15 is movably connected to the surface of the rotating cylinder 14, a spiral groove is provided on the surface of the rotating cylinder 14, a limiting block fixed to the inner wall of the upper shell 11 and cooperating with the spiral groove is provided in the spiral groove, a long spring is provided on the lower side of the rotating cylinder 14 to push it, the long spring pushes the rotating cylinder 14 so that it has upward elastic potential energy, and the moving rotating cylinder 14 is rotated, extended or retracted under the action of the spiral groove and the limiting block on its surface, so that the clamping block 13 and the cover door are separated or locked.

[0055] Furthermore, one side of the rotating rod 151 is coaxially fixedly connected to a limiting ring 152, a filling block 111 is provided in the upper shell 11, and a first card slot 112 and a second card slot 113 are provided on the filling block 111, the rotating rod 151 is rotatably embedded in the inner side of the first card slot 112, and the limiting ring 152 is rotatably embedded in the inner side of the second card slot 113, and a top block 121 is provided on the surface of the lower cover plate 12 for sliding against the arc surface on the other side of the limiting ring 152, and the filling block 111 is also used for limiting the activity space of the lock plate body 16, and the limiting ring 152 is clamped by the top block 121 and the second card slot 113, so that the lift body 15 is rotatably installed on the inner side of the upper shell 11, and the inner wall where the first card slot 112 and the second card slot 113 are connected can limit the side of the limiting ring 152, so as to avoid the rotation circumferential deviation of the rotating rod 151, which causes the lift body 15 to malfunction.

[0056] Working principle: When the vehicle is driving on a bumpy road, vibration and wear occur between the tilting member body 15 and the lock plate body 16. The swing assembly 21 vibrates with the lock body and the vehicle body, and swings back and forth. Then the fixed rod 222 rotates and rotates through the swing of the swing assembly 21, causing the active crown gear 224 to rotate and push the driven crown gear 225 to move linearly downward, driving the extrusion block 226 to move up and down. Because the upper surface of the oil bag 232 and the lower surface of the extrusion block 226 are tightly bonded, the reciprocating motion of the extrusion block 226 causes the oil bag 232 to reciprocate and contract, pumping the hydraulic oil in the oil box 233 into the oil cylinder 231, pushing the piston plate 2311 to move downward, so that the arc block 234 is squeezed onto the surface of the damping ring 153, and the rubber extrusion pad 2341 undergoes a certain deformation to push the damping ring 15 3 is pressed tightly, so as to lock the rotation of the tilting member body 15. Among them, since the flow rate of liquid passing through the third one-way valve 2331 is smaller than that of the second one-way valve 2322 under the same hydraulic pressure, it takes a certain amount of time for the hydraulic oil in the oil cylinder 231 to return to the oil box 233 through the third one-way valve 2331. Therefore, the arc block 234 can be kept pressed on the surface of the damping ring 153 for a period of time. When the vehicle body is in a state of continuous bumping, the oil bag 232 continues to reciprocate and contract, and the hydraulic oil is continuously pumped into the oil cylinder 231. The oil cylinder 231 maintains hydraulic oil in a high-pressure state, so that the arc block 234 keeps pressing the damping ring 153. When the vehicle body is in a bumpy state, the tilting member body 15 is always in a locked state, so that unnecessary wear between the tilting member body 15 and the lock plate body 16 due to vibration is avoided.
