Technical Field
[0001] The utility model relates to the technical field of automobile handles, in particular to a mechanically retractable automobile handle. Background Art
[0002] When a car is driving, wind resistance is generated around the car, and the protruding handles will increase the drag coefficient. Therefore, many existing cars have hidden handles to reduce wind resistance, reduce fuel consumption of oil cars or increase the cruising range of electric cars.
[0003] A Chinese patent with application number 201921213219.4 discloses an automatic swinging outer handle structure for a vehicle, comprising a handle base fixed in the vehicle body; a handle body hidden in the handle base and flush with the vehicle body, the handle body being rotatably connected to the handle base and capable of moving between an initial hidden state and a pre-deployed state; an electric ejection mechanism capable of moving the handle body from the initial hidden state to the pre-deployed state; the electric ejection mechanism comprising an actuator, a rotating arm, a push rod and a slider, the rotating arm being rotatably connected to the handle base, the two ends of the rotating arm being respectively connected to the actuator and the push rod, a sliding cavity being provided in the handle base, the slider being movably arranged in the sliding cavity, a control chamber being provided in the slider, the push rod being staggered with the control chamber, the front end of the handle body being inserted into the control chamber from one side, and an unlocking block being further included, the unlocking block being abutted against the handle body, and a pull wire for unlocking the vehicle door being connected to the unlocking block.
[0004] The solution starts the actuator, which drives the push rod to be inserted into the control room from the other side, so that the push rod drives the slider to move along the sliding cavity toward the inside of the vehicle body, and then the slider abuts against the front end of the handle body and causes the handle body to rotate, so that the handle body moves from an initial hidden state to a pre-deployed state, exposed outside the door for grasping, and then the handle body is pulled so that the handle body continues to flip outward from the pre-deployed state to a fully deployed state, completing the unlocking between the door and the frame so that the door can be opened.
[0005] However, the electric ejection mechanism in the above solution is expensive, and in bad weather, such as cold conditions, the accuracy of electronic instruments such as actuators decreases, malfunctions or even damage occur, and the maintenance cost is high. Utility Model Content
[0006] The utility model aims at the disadvantages of the hidden handle in the prior art, such as high manufacturing cost and maintenance cost, high failure rate, etc., and provides a mechanical retractable automobile handle.
[0007] In order to solve the above technical problems, the utility model is solved by the following technical solutions:
[0008] A mechanical retractable automobile handle comprises a handle body and a receiving groove which is recessed on a vehicle door and can completely receive the handle body. The handle body comprises a gripping portion which is arranged outward and a matching portion which is guided to move in the receiving groove. A matching structure which is provided in the receiving groove and which realizes receiving the handle body in the receiving groove when the matching portion is retracted inward to a first stroke and releases the position limit of the matching portion when the matching portion is further retracted inward to a second stroke. A first elastic member which drives the handle body to extend outward when the matching portion is retracted to the second stroke and the thrust is removed is provided in the receiving groove. A rotating part is rotatably provided at the opening of the accommodating groove, which can unlock the vehicle door and the vehicle frame when it is flipped outward. A baffle is vertically protruded on the outer wall of the rotating part between the gripping part and the matching part, which limits the matching part from leaving the accommodating groove when the matching part extends outward under the elastic force of the first elastic member. A limiting structure is provided between the baffle and the matching part, which can lock the baffle and the matching part when the matching part extends outward and unlock the two under the action of thrust. When the limiting structure realizes the locking between the matching part and the rotating part, the handle body can be pulled to make the handle body and the rotating part flip outward synchronously.
[0009] By adopting the above scheme, when the car is driving normally, the handle body is stored and hidden in the accommodating groove, that is, it is limited to the first stroke by the matching structure. When the car door needs to be opened, the gripping part is pushed to retract it to the second stroke in the accommodating groove, and the matching structure releases the limitation on the matching part, and the first elastic member is squeezed to generate elastic force. At this time, the thrust on the gripping part is removed, and the first elastic member drives the handle body to extend outward until the gripping part is located outside the car door and the matching part abuts against the baffle. The limiting structure realizes the locking between the matching part and the rotating part. The user grasps the gripping part, and the handle body can be flipped outward synchronously with the rotating part, so that the car door and the frame are unlocked; after opening the car door, the gripping part is pushed to retract into the accommodating groove until the car handle retracts to the first stroke, and the matching part of the matching structure limit realizes the storage and hiding of the handle body in the accommodating groove.
[0010] Preferably, the mating part includes a moving part close to the bottom of the accommodating groove and a connecting part respectively connected to the moving part and the grasping part at both ends. After the grasping part, the moving part and the connecting part are connected, a "U-shaped" handle body with an opening toward the rotating part is formed. When the handle body extends outward, the grasping part is located outside the accommodating groove for grasping, and the limiting structure is arranged between the moving part and the baffle.
[0011] By adopting the above scheme, the handle body is in a "U-shape" with the opening facing the rotating part, and the baffle is located between the moving part and the grasping part, ensuring that the handle body can be smoothly extended and retracted in the accommodating groove. The moving part is located in the accommodating groove at the lower limit under the action of the baffle to prevent the handle body from falling out, and the grasping part is easy to grasp after extending out of the accommodating groove.
[0012] Preferably, the limiting structure includes a limiting block convexly provided on a side of the baffle plate close to the moving part and a limiting groove concavely provided on the moving part for the limiting block to be inserted into when the handle body extends outward.
[0013] By adopting the above scheme, the handle body extends outward under the action of the first elastic member. In the process of the movable part moving outward to abut against the baffle, the limit block is inserted into the limit groove to form a limit, thereby limiting the horizontal movement between the handle body and the baffle, ensuring that when the handle body is pulled outward, the handle body and the rotating part can be flipped outward synchronously.
[0014] Preferably, a magnetic attraction structure is provided between the limit block and the limit groove to limit the handle body from detaching from the baffle when it is flipped outward, and the magnetic attraction structure includes an iron sheet fixedly provided on the side of the limit block away from the baffle and a magnet fixedly provided at the bottom of the limit groove and capable of magnetic attraction to the iron sheet.
[0015] By adopting the above scheme, the locking and limiting ability between the handle body and the baffle is further strengthened through the magnetic attraction of the magnet and the iron sheet, and the magnetic attraction structure can also provide magnetic attraction force when the handle body is extended outward, so that the handle body can move outward more quickly. In addition, the magnetic attraction structure can further increase the accuracy of the limit block inserted into the limit groove.
[0016] Preferably, the matching structure includes a card slot recessed on one end of the moving part away from the connecting part, a telescopic slot recessed on the side wall of the accommodating groove, and a card block elastically and telescopically arranged in the telescopic slot and partially inserted into the card slot, the card block is provided with an extrusion inclined surface for driving the card block to retract into the telescopic slot when the moving part retracts to abut against the card block, an air cavity is recessed at the bottom of the accommodating groove, a sealing plate is provided in the air cavity for sealing and moving, and the sealing plate moves along the retraction direction of the moving part as the moving part moves from the first stroke to the second stroke, a traction structure is provided between the sealing plate and the card block, and the traction structure retracts the card block into the telescopic slot as the sealing plate moves along the retraction direction of the moving part, and a delay structure is provided at the bottom of the air cavity for delaying the reset speed of the sealing plate and the card block.
[0017] When the handle is retracted to the first stroke, the movable part first contacts the extrusion inclined surface, driving the card block to retract elastically into the telescopic groove until the handle is moved to the first stroke, that is, the card slot on the movable part is opposite to the telescopic groove. At this time, the card block elastically extends out partially and is inserted into the card slot for locking and limiting, so that the handle is hidden and stored in the accommodating groove; when the handle is continuously pushed to retract to the second stroke, the card slot and the extrusion inclined surface are squeezed to drive the card block to retract into the telescopic groove, and the movable part can continue to retract inward, and the extrusion sealing plate moves along the retraction direction of the movable part, and the state of the card block retracting into the telescopic groove is ensured by the traction structure and the card block continues to retract into the telescopic groove. At this time, after the thrust is removed, the handle is instantly extended outward under the action of the first elastic member, and due to the existence of the delay structure, the sealing plate is slowly reset, so that the card block also slowly extends out of the telescopic groove, thereby ensuring that when the movable part passes through the telescopic groove, the card block is still in the telescopic groove and will not interfere with or hinder the movement of the movable part.
[0018] Preferably, the traction structure includes a pull rope whose two ends are respectively fixedly connected to one side of the block close to the bottom of the telescopic groove and to one side of the sealing plate close to the moving part, and a through groove is provided between the bottom of the telescopic groove and the air cavity for the pull rope to pass through and move.
[0019] By adopting the above scheme, when the sealing plate moves along the retraction direction of the moving part, the pull rope drives the clamping block to retract into the telescopic part; conversely, after the handle body is extended outward, the resistance on the sealing plate disappears, and due to the elastic expansion and contraction of the clamping block, the clamping block partially extends out of the telescopic groove and is reset. During this process, the sealing plate is pulled along the extension direction of the moving part and is reset by the pull rope.
[0020] Preferably, a second elastic member is provided between the bottom of the telescopic slot and a side of the clamping block close to the bottom of the telescopic slot for driving the clamping block to partially extend out of the telescopic slot under normal conditions.
[0021] By adopting the above scheme, when the card block retracts into the telescopic groove, the second elastic member is squeezed to generate elastic force. When the squeezing force from the moving part on the card block disappears or the pulling force from the pull rope on the card block disappears, the second elastic member drives the card block to partially extend and reset, and at the same time, the sealing plate is pulled by the pull rope to move and reset along the extending direction of the moving part.
[0022] Preferably, the delay structure includes an air outlet one-way valve and an air exhaust and air supply hole arranged at the bottom of the air cavity, and the air outlet speed of the air outlet one-way valve is much greater than the air intake speed of the air exhaust and air supply hole.
[0023] By adopting the above scheme, when the sealing plate moves along the retraction direction of the movable part, the gas in the air cavity is quickly discharged through the air outlet one-way valve and the exhaust and air supply holes, that is, the sealing plate and the air cavity are kept at a normal pressure state; when the sealing plate moves along the extension direction of the movable part, only the exhaust and air supply holes take in air and the air intake speed is slow. The reset speed of the sealing plate and the block depends on the air intake speed of the exhaust and air supply holes, so the two are reset slowly.
[0024] Preferably, when the card block is inserted into the card slot, the side of the gripping portion away from the moving portion is flush with the outer side of the door, and the distance between the gripping portion and the baffle is greater than the length of the card block exposed outside the telescopic slot.
[0025] With the above solution, the side of the gripping part away from the moving part is flush with the outside of the door, which ensures the beauty of the door while minimizing the wind resistance caused by the car handle under this setting. The gripping part retracts to the second stroke, that is, the gripping part abuts against the baffle. Since the distance between the gripping part and the baffle is greater than the length of the block exposed outside the telescopic slot, when the gripping part abuts against the baffle, it can be ensured that the block retracts to a certain stroke in the telescopic slot, ensuring that when the handle body extends outward, the block will not hinder the movement of the moving part.
[0026] The utility model has significant technical effects due to the adoption of the above technical solutions: the gripping part is pushed to make the handle body retract into the receiving groove and hide, and the handle body is restricted from extending outward by the card block and the card slot, so that the handle body is stored, which is the initial hidden state; when in use, it is only necessary to continue to push the gripping part inward, squeeze the sealing plate to move along the retraction direction of the moving part, and make the card block located in the telescopic groove by the pull rope, remove the external force, and under the action of the first elastic member, the gripping part extends out of the door for gripping, and the moving part and the baffle are locked, which is the pre-expanded state; the user pulls the gripping part outward to drive the rotating part to flip outward, and the door is unlocked, which is the fully expanded state. After the door is opened, the gripping part is pushed to make the handle body retract into the receiving groove and continue to hide. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.
[0042] Example
[0043] A mechanical retractable car handle, referring to Figures 1 to 13 , including a door 1. Since the door 1 and the installation and switch method between the door 1 and the frame are prior art, in this embodiment Figures 2 to 13 A partial schematic diagram of the vehicle door 1 is provided, which is mainly used to describe the installation method between the vehicle handle and the vehicle door 1 and the extension and retraction process of the vehicle handle in the vehicle door 1.
[0044] The automobile handle includes a handle body 2. A receiving groove 3 is recessed on the vehicle door 1. The handle body 2 can partially extend out of the receiving groove 3 to facilitate gripping and opening the door, and can also be retracted and hidden in the receiving groove 3. When the handle body 2 is received in the receiving groove 3, the outer surface of the handle body 2 is flush with the surface of the vehicle door 1, ensuring beauty and minimizing the wind resistance caused by the handle body 2.
[0045] The handle body 2 includes a gripping portion 201 disposed outwardly, a matching portion 202 guided to move in the receiving groove 3, and the matching portion 202 includes a moving portion 2021 and a connecting portion 2022 connecting the gripping portion 201 and the moving portion 2021, that is, the gripping portion 201, the moving portion 2021 and the connecting portion 2022 are connected to form a "U-shaped" handle body 2, and the opening faces the rotating portion 5. A rotating portion 5 is rotatably disposed at the opening of the receiving groove 3, and when flipped outward, the door 1 and the frame can be unlocked. A baffle 6 is vertically protruded on the outer wall of the rotating portion 5 between the gripping portion 201 and the moving portion 2021.
[0046] The handle body 2 is retracted in the accommodating groove 3. When it extends outward, the gripping portion 201 is located outside the vehicle door 1 for easy gripping, and the moving portion 2021 abuts against the baffle 6, preventing the entire handle body 2 from escaping from the accommodating groove 3 under the limitation of the baffle 6.
[0047] A limiting structure is arranged between the baffle plate 6 and the opposite side of the movable part 2021, and the limiting structure includes a limiting block 7 convexly arranged on the baffle plate 6 and a limiting groove 8 concavely arranged on the movable part 2021. The limiting groove 8 and the limiting block 7 are always opposite to each other during the movement of the movable part 2021 in the accommodating groove 3. Therefore, during the process of the movable part 2021 moving outward until it abuts against the baffle plate 6, the limiting block 7 can be inserted into the limiting groove 8 for limiting.
[0048] An iron sheet 9 is fixedly provided on the side of the limit block 7 away from the baffle 6, and a magnet 10 is fixedly provided at the bottom of the limit groove 8, which further strengthens the locking and limiting ability between the handle body 2 and the baffle 6. The magnetic attraction provided by the magnet 10 can also make the limit block 7 inserted into the limit groove 8 faster and more accurately. An introduction slope is provided on the side of the limit block 7 away from the baffle 6 to facilitate the insertion of the limit block 7 into the limit groove 8.
[0049] After the handle body 2 is extended outward, it is relatively still with the baffle 6 through the limiting structure, that is, it is relatively still with the rotating part 5. At this time, it is the pre-expanded state of the handle body 2, and the gripping part 201 is located outside the vehicle door 1. The user grasps the gripping part 201 and pulls it outward, so that the rotating part 5 is synchronously flipped outward, that is, it changes from the pre-expanded state to the fully expanded state, thereby realizing the unlocking between the vehicle door 1 and the vehicle frame, and the vehicle door 1 can be opened.
[0050] Most of the existing vehicles can unlock the door 1 by holding the handle and flipping it outward. Combined with the description in the background technology, it can be known that the method of unlocking the door 1 by flipping the handle body 2 and the rotating part 5 outward to change the car handle from a pre-deployed state to a fully deployed state is prior art. Therefore, the unlocking method of the door 1 and the unlocking structure of the door 1 are not shown in the figure in this embodiment and will not be described in detail. For details, please refer to the unlocking structure in the comparative patent in the background technology.
[0051] A torsion spring is provided between the rotating part 5 and the accommodating groove 3, which drives the rotating part 5 to rotate inward and reset when the external force on the rotating part 5 is removed. The rotating part 5 flips inward and resets, driving the handle body 2 to rotate inward. The setting of the torsion spring is the existing technology, which is not shown in the figure and will not be described here.
[0052] When the vehicle door 1 is opened, the external force is removed, and the handle body 2 and the rotating part 5 rotate inwards to reset, pushing the gripping part 201 to retract the handle body 2 inwards until the outer side of the gripping part 201 is flush with the outer side of the vehicle door 1.
[0053] A slot 11 is recessed on one side of the moving part 2021 away from the connecting part 2022, and a telescopic slot 12 is recessed on the side wall of the accommodating slot 3. A block 13 is partially telescopically arranged in the telescopic slot 12, and an extrusion slope 14 is arranged on the block 13. A second elastic member 19 is arranged between the bottom of the telescopic slot 12 and the side of the block 13 close to the bottom of the telescopic slot 12. During the retraction process of the moving part 2021, the moving part 2021 first abuts against the extrusion slope 14, and then drives the block 13 to retract into the telescopic slot 12. At this time, the second elastic member 19 is squeezed to generate elastic force until the slot 11 and the telescopic slot 12 are facing each other. Under the action of the second elastic member 19, the block 13 partially extends out and inserts into the slot 11, limiting the outward movement of the handle body 2. At this time, the outer side of the gripping part 201 is flush with the outer side of the door 1. This is the first stroke, which is also the initial hidden state of the handle body 2. In this embodiment, the second elastic member 19 is a second spring.
[0054] When the handle body 2 is used, it is necessary to switch from the initial hidden state to the pre-expanded state. Therefore, an air cavity 15 is recessed at the bottom of the accommodating groove 3, and a sealing plate 16 is provided in the air cavity 15 for sealing and moving. When the moving part 2021 continues to retract inward from the first stroke, the sealing plate 16 is driven to move along the retraction direction of the moving part 2021. Since a pull rope 17 is fixedly provided on one side of the block 13 close to the bottom of the telescopic groove 12, and the other end of the pull rope 17 is fixedly connected to the side of the sealing plate 16 close to the moving part 2021, the movement of the seal along the retraction direction of the moving part 2021 will drive the block 13 to retract into the telescopic groove 12. When the moving part 2021 is in the first stroke, the distance between the gripping part 201 and the baffle 6 is greater than the length of the block 13 exposed outside the telescopic groove 12. There is a through groove 18 between the bottom of the telescopic groove 12 and the air cavity 15 for the pull rope 17 to pass through and move.
[0055] Due to the existence of the extrusion slope 14, during the process of the moving part 2021 continuing to retract inward from the first stroke, the compression of the card slot 11 and the extrusion slope 14 can drive the card block 13 to retract into the telescopic slot 12, and the moving part 2021 can continue to retract inward, and the gripping part 201 moves to abut against the baffle 6. At this time, the handle body 2 cannot continue to retract. This is the second stroke. During the process of the moving plate moving from the first stroke to the second stroke, the extrusion sealing plate 16 moves along the retraction direction of the moving part 2021. Since the distance between the gripping part 201 and the baffle 6 is greater than the length of the card block 13 exposed outside the telescopic slot 12, the sealing plate 16 ensures that the card block 13 is retracted into the telescopic slot 12 through the pull rope 17 during the movement of the moving part 2021 and drives the card block 13 to continue to retract into the telescopic slot 12.
[0056] A first elastic member 4 is fixedly disposed at the bottom of the accommodating groove 3. When the moving part 2021 is in the first stroke, the end of the first elastic member 4 away from the accommodating groove 3 is in close contact with or has a clearance fit with the moving part 2021. An air outlet check valve 20 and an exhaust and air supply hole 21 are disposed at the bottom of the air cavity 15. The air outlet speed of the air outlet check valve 20 is much greater than the air intake speed of the exhaust and air supply hole 21. In this embodiment, the first elastic member 4 is a first spring.
[0057] When the sealing plate 16 moves along the retraction direction of the moving part 2021, the gas in the air cavity 15 is quickly discharged through the gas outlet check valve 20 and the exhaust and air supply hole 21, that is, the sealing plate 16 and the air cavity 15 are kept in a normal pressure state, at which time the first elastic member 4 is squeezed to generate elastic force; when the thrust on the handle body 2 disappears, the sealing plate 16 moves along the extension direction of the moving part 2021 under the action of the first elastic member 4, only the exhaust and air supply hole 21 is inlet, and the air intake speed is slow, and the reset speed of the sealing plate 16 and the block 13 depends on the air intake speed of the exhaust and air supply hole 21. Therefore, the handle body 2 extends outward instantly under the action of the first elastic member 4, and the sealing plate 16 slowly resets, so that the card block 13 also slowly extends out of the telescopic slot 12, thereby ensuring that when the movable part 2021 passes through the telescopic slot 12, although the card block 13 moves away from the bottom of the telescopic slot 12, the card block 13 is still in the telescopic slot 12 and will not interfere with or hinder the movement of the movable part 2021. The movable part 2021 extends outward under the action of the first elastic member 4 and abuts against the baffle 6, so that the handle body 2 can be smoothly in the pre-deployed state.
[0058] Under normal conditions, the handle body 2 is hidden in the accommodating groove 3, which is the initial hidden state; when the door 1 needs to be opened, it is only necessary to push the gripping portion 201 inward, and the side wall of the card slot 11 and the extrusion slope 14 squeeze and slide to drive the card block 13 to retract into the telescopic groove 12, ensuring that the handle body 2 can continue to retract inward. During the inward retraction of the moving portion 2021, the sealing plate 16 is squeezed and moved along the retraction direction of the moving portion 2021 while squeezing the first elastic member 4 to generate elastic force. The sealing plate 16 ensures that the card block 13 is located in the telescopic groove 12 through the pull rope 17, and the external force is removed. Under the action of the first elastic member 4, the gripping portion 201 extends out of the vehicle door 1 for gripping, and the movable portion 2021 extends outward and is locked between the baffle 6 by the limit block 7 and the limit groove 8, which is the pre-deployment state; the user pulls the gripping portion 201 outward to drive the rotating portion 5 to flip outward, completing the unlocking of the vehicle door 1, which is the fully deployed state; after the vehicle door 1 is opened, the rotating portion 5 and the handle body 2 flip inward and reset, and then push the gripping portion 201 to make the handle body 2 retract into the accommodating groove 3 to continue to be hidden, and the limiting is achieved by the block 13 and the slot 11.
[0059] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
