Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an inner handle for mechanical unlocking by pressing an electronic unlocking button and an unlocking method thereof. Background Art

[0002] As social standards continue to improve, more and more families choose cars as their means of transportation, and as the level of the automobile industry continues to improve, the requirements for car safety are also constantly increasing.

[0003] In the existing automotive field, inner door handles are generally unlocked electronically or mechanically by pressing a button. Although electronic unlocking is more convenient and faster than mechanical unlocking, it is prone to malfunction and cannot be unlocked in some emergency situations. Therefore, according to market requirements, some automobile companies have developed inner door handles that can achieve both electronic unlocking and mechanical unlocking by pressing a button.

[0004] However, the existing inner handle is prone to accidental triggering of the electronic unlocking and opening of the door due to the passenger's accidental touch, the mechanical unlocking rebound caused by the handle being pulled, or the acceleration caused by the door being hit, causing the handle to press the switch, causing the electronic unlocking and opening of the door to be mistakenly triggered, causing inconvenience in use and easily posing a safety hazard. Summary of the Invention

[0005] In order to solve the technical problems existing in the background technology, the present invention proposes an inner handle with mechanical unlocking by pressing electronic unlocking and an unlocking method thereof.

[0006] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0007] The inner handle for mechanical unlocking is opened by pressing the electronic unlocking, comprising a base, an unlocking handle rotated in the base, the base being provided with a folding groove, and the unlocking handle being folded in the folding groove;

[0008] The base is provided with a mechanical unlocking structure for mechanical unlocking and an electronic unlocking structure for electronic unlocking, and has an electrical unlocking stroke and a mechanical unlocking stroke that are relatively arranged;

[0009] The unlocking handle is connected to the unlocking end of the mechanical unlocking structure and brakes the mechanical unlocking structure during the mechanical unlocking stroke. The electronic unlocking structure is provided with a blocking portion that blocks the unlocking handle from approaching the unlocking end of the electronic unlocking structure. The blocking portion separates an idling stroke during the electrical unlocking stroke, and the unlocking handle overcomes the blocking portion and brakes the electronic unlocking structure.

[0010] Preferably, the electronic unlocking structure includes a mounting shell connected to the base, an unlocking control module disposed at the bottom of the mounting shell, an unlocking button slidably disposed within the mounting shell, and a conductive rubber member disposed between the unlocking button and the unlocking control module. With this improvement, when electronic unlocking is required, the unlocking handle can be pressed inward, causing the unlocking handle to squeeze the unlocking button, which in turn squeezes the conductive rubber member. The conductive rubber member contains conductive particles, which contact conductive particles on the unlocking control module, thereby connecting the unlocking control module's PCB circuitry and sending an unlocking signal to the onboard computer, achieving electronic unlocking.

[0011] Preferably, the conductive rubber is formed with a first protrusion for electronic unlocking, and the blocking portion includes a second protrusion formed on the conductive rubber. The second protrusion is higher than the first protrusion, and the height difference between the second protrusion and the first protrusion constitutes the idle travel of the unlock handle. With this improvement, when the unlock handle rotates inward, the unlock button first abuts the second protrusion. Only after the second protrusion is squeezed to a certain extent will the unlock button abut the first protrusion, thereby preventing the unlock handle from being accidentally touched by the passenger, causing electronic unlocking and opening the door.

[0012] Preferably, a sliding groove for the unlock button is formed within the mounting shell, and the unlock button is formed with a blocking protrusion. The blocking protrusion abuts the mounting shell to limit the unlock button's continued movement toward the conductive rubber. When the blocking protrusion abuts the mounting shell, the unlock button abuts the first protrusion, forcing the first protrusion to contact the unlock control module for electronic unlocking. This improvement limits the unlock button's sliding travel. When the unlock button moves inward a specified distance, the blocking protrusion abuts the mounting shell. At this point, the unlock button has abutted the first protrusion, limiting the unlock button's sliding travel, preventing the unlock button from excessively squeezing the conductive rubber and causing damage to the internal structure, thereby extending the handle's service life.

[0013] Preferably, the unlock handle has at least a retracted state, retracted within the retracted slot, and an inwardly rotated electronic unlocking state. When the unlock handle is in the retracted state, the unlock button abuts the second protrusion, and when the unlock handle is in the electronic unlocking state, the unlock button abuts the first and second protrusions simultaneously. With the above improvements, when electronic unlocking is performed, the obstruction of the second protrusion must be overcome first, and the second protrusion must be squeezed to a certain degree before the unlock handle abuts the first protrusion to unlock. This prevents the electronic unlocking from being accidentally triggered by a passenger, the unlock handle rebounding when the mechanical unlock is activated, or the door being accidentally triggered by acceleration due to an impact.

[0014] Preferably, a limiting protrusion is formed in the mounting housing, and a limiting groove is formed in the unlocking button, and the limiting protrusion is inserted into the limiting groove. Through the above improvement, the limiting groove and the limiting protrusion cooperate to ensure the stability of the unlocking button during the sliding process, thereby preventing the unlocking button from deviating and causing poor contact during the unlocking process.

[0015] Preferably, a limiting rib is formed within the retraction groove, which abuts the unlock handle to limit further inward rotation of the unlock handle. When the limiting rib abuts the unlock handle, the unlock button abuts the first protrusion, forcing the first protrusion to contact the unlock control module to perform electronic unlocking. With this improvement, the limiting rib can limit the inward rotational range of the unlock handle, thereby preventing excessive compression of the conductive rubber and damage to the internal structure, thereby ensuring the service life during subsequent use.

[0016] Preferably, a rotating shaft is provided in the retracting groove, the unlocking handle is rotated on the rotating shaft, and an elastic element is sleeved on the rotating shaft, one end of the elastic element abuts the base and the other end abuts the unlocking handle, so that the unlocking handle is retracted into the retracting groove, and the mechanical unlocking structure includes an unlocking pull cord, which is connected to the unlocking handle, and the unlocking handle rotates outward, and the unlocking pull cord is pulled to mechanically unlock. With the above improvement, when mechanical unlocking is required, the unlocking handle can be pulled outward, so that the unlocking handle pulls the unlocking pull cord to unlock, thereby achieving mechanical unlocking. After mechanical unlocking is completed, the unlocking handle will be retracted into the base under the action of the elastic element.

[0017] Preferably, a shock-absorbing pad is provided within the base, and when the unlock handle retracts into the base, it contacts the shock-absorbing pad. With the above improvements, after mechanical unlocking is completed, the unlock handle rebounds under the action of the elastic element, and the unlock handle contacts the shock-absorbing pad, reducing vibration and preventing accidental activation of the electronic unlocking mechanism.

[0018] The method for unlocking the inner handle by pressing the electronic unlocking to activate the mechanical unlocking includes the following steps:

[0019] S0 Unlock method selection: Choose mechanical unlocking or electronic unlocking. You can pull the unlock handle outward for mechanical unlocking or press the unlock handle inward for electronic unlocking.

[0020] S1 performs mechanical unlocking: Pull one end of the unlock handle outward to rotate it, and the other end of the unlock handle pulls the unlock rope to mechanically unlock. After unlocking is completed, the unlock handle is retracted into the base under the action of the elastic element;

[0021] S2 performs electronic unlocking: press the unlock handle inward to rotate the unlock handle inward, and squeeze the unlock button. The unlock button slides in the mounting shell, and the unlock handle first enters the idling stroke. The unlock button first abuts against the second convex portion. After the second convex portion is compressed to a certain extent, the unlock button abuts against the first convex portion, so that the first convex portion drives the unlock control module to start electronic unlocking. After unlocking is completed, the unlock button pushes the unlock handle back to its initial position.

[0022] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0023] By providing a blocking part on the electronic unlocking structure to block the unlocking handle from approaching the unlocking end of the electronic unlocking structure, the unlocking handle needs to overcome the obstruction of the blocking part before squeezing the electronic unlocking structure, and can only contact the unlocking end of the electronic unlocking structure after completing a certain idling stroke, thereby avoiding accidental touch by passengers, mechanical unlocking rebound caused by the unlocking handle, or acceleration falsely triggered by the door being hit, causing the electronic unlocking to open, thereby improving the user experience.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0032] It should be understood that although terms such as upper, middle, lower, top, end, etc. appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for ease of understanding, and are not used to define any direction or order limitation.

[0033] like Figure 1-6 As shown, the inner handle for mechanical unlocking by pressing the electronic unlocking comprises a base 1, an unlocking handle 2 rotated inside the base 1, a retracting groove 3 is formed on the base 1, and the unlocking handle 2 is retracted in the retracting groove 3;

[0034] Specifically, a mechanical unlocking structure 4 for mechanical unlocking and an electronic unlocking structure 5 for electronic unlocking are provided in the base 1, and have an electrical unlocking stroke and a mechanical unlocking stroke which are relatively arranged;

[0035] The unlocking handle 2 is connected to the unlocking end of the mechanical unlocking structure 4 and brakes the mechanical unlocking structure 4 during the mechanical unlocking stroke. The electronic unlocking structure 5 is provided with a blocking portion 6 that blocks the unlocking handle 2 from approaching the unlocking end of the electronic unlocking structure 5. The blocking portion 6 separates the idling stroke during the electrical unlocking stroke, and the unlocking handle 2 overcomes the blocking portion 6 and brakes the electronic unlocking structure 5.

[0036] Among them, the outward rotation stroke of the unlocking handle 2 is the mechanical unlocking stroke, and the inward rotation stroke is the electrical unlocking stroke. A blocking part 6 is provided on the electronic unlocking structure 5 to block the unlocking handle 2 from approaching the unlocking end of the electronic unlocking structure 5. When the unlocking handle 2 squeezes the electronic unlocking structure 5 for electronic unlocking, it needs to overcome the obstruction of the blocking part 6. In the process of overcoming the obstruction of the blocking part 6, the unlocking handle 2 can only contact the unlocking end of the electronic unlocking structure 5 after completing a certain idling stroke, thereby avoiding accidental touch by passengers, mechanical unlocking rebound caused by the unlocking handle, or accidental triggering of acceleration caused by collision to open the door, thereby improving the user experience.

[0037] like Figure 2-6 As shown, in this embodiment, the electronic unlocking structure 5 includes a mounting shell 101 connected to the base 1, an unlocking control module 102 arranged at the bottom of the mounting shell 101, an unlocking button 103 slidably arranged in the mounting shell 101, and a conductive rubber 104 arranged between the unlocking button 103 and the unlocking control module 102.

[0038] Furthermore, the unlocking control module 102 includes a pin assembly for connecting the PCB boards, and conductive particles are provided on the PCB boards, and conductive particles are also provided in the conductive rubber 104 .

[0039] When electronic unlocking is required, the unlocking handle 2 can be pressed inward, so that the unlocking handle 2 squeezes the unlocking button 103, and the unlocking button 103 squeezes the conductive rubber 104. The conductive particles in the conductive rubber 104 come into contact with the conductive particles on the unlocking control module 102, the PCB board circuit is connected, and the pin assembly outputs a signal to the on-board computer to achieve electronic unlocking.

[0040] Specifically, a first protrusion 105 for electronic unlocking is formed on the conductive rubber 104, and the blocking portion 6 includes a second protrusion 106 formed on the conductive rubber 104. The second protrusion 106 is higher than the first protrusion 105. The height difference between the second protrusion 106 and the first protrusion 105 constitutes the idle travel of the unlocking handle 2.

[0041] When the unlocking handle 2 rotates inward, the unlocking button 103 first abuts against the second protrusion 106. When the second protrusion 106 is squeezed to a certain extent, the unlocking button 103 abuts against the first protrusion 105, thereby preventing the unlocking handle 2 from being accidentally touched by the passenger, resulting in electronic unlocking and opening the door.

[0042] Preferably, the first protrusion 105 is centrally arranged on the conductive rubber 104, and the second protrusions 106 are spaced apart around the first protrusion 105 to avoid accidental touching of the first protrusion 105 due to tilt of the unlock button 103, thereby further improving the reliability of electronic unlocking.

[0043] In addition, the unlocking handle 2 has at least a folded state folded in the folding groove 3 and an electronic unlocking state rotated inward. When the unlocking handle 2 is in the folded state, the unlocking button 103 abuts against the second protrusion 106, and when the unlocking handle 2 is in the electronic unlocking state, the unlocking button 103 abuts against the first protrusion 105 and the second protrusion 106 at the same time.

[0044] Therefore, when performing electronic unlocking, it is necessary to overcome the obstruction of the second protrusion 106 first, and only after the second protrusion 106 is squeezed to a certain extent can the unlocking handle 2 abut against the first protrusion 105 to unlock, thereby avoiding the passenger's accidental touch, the unlocking handle opening the mechanical unlocking rebound, or the car door being hit to generate acceleration false triggering causing the electronic unlocking to open the door. After the electronic unlocking is completed, the hand releases the unlocking handle, and the first protrusion 105 and the second protrusion 106 will push the unlocking button 103 out, and the unlocking handle is reset under the action of the unlocking button 103.

[0045] like Figure 2-6As shown, regarding the further unlocking of the structural cooperation of the electronic unlocking structure 5 in this embodiment, a sliding groove 201 for the unlocking button 103 to slide is formed in the mounting shell 101, and a blocking protrusion 202 is formed on the unlocking button 103. The blocking protrusion 202 abuts against the mounting shell 101. When the blocking protrusion 202 abuts against the mounting shell 101, the unlocking button 103 abuts against the first protrusion 105.

[0046] Furthermore, the blocking protrusion 202 can limit the unlocking button 103 from continuing to move toward the conductive rubber 104. The blocking protrusion 202 will abut against the mounting shell 101. At this time, the unlocking button 103 has already abutted against the first protrusion 105, which can limit the sliding stroke of the unlocking button 103, preventing the unlocking button 103 from excessively squeezing the conductive rubber 104 and causing damage to the internal structure, thereby improving the service life.

[0047] In addition, a limiting protrusion 203 is formed in the mounting shell 101, and a limiting groove 204 is formed in the unlocking button 103. The limiting protrusion 203 is placed in the limiting groove 204, and the limiting groove 204 cooperates with the limiting protrusion 203 to ensure the stability of the unlocking button 103 during the sliding process, thereby avoiding the unlocking button 103 from being offset and causing poor contact during the unlocking process.

[0048] In some other embodiments, a limiting rib 205 is formed in the retraction groove 3, and the limiting rib 205 abuts against the unlocking handle 2 to limit the unlocking handle 2 from continuing to rotate inward. When the limiting rib 205 abuts against the unlocking handle 2, the unlocking button 103 abuts against the first protrusion 105 and forces the first protrusion 105 to contact the unlocking control module 102 for electronic unlocking.

[0049] The limiting rib 205 can limit the inward rotational travel of the unlocking handle 2 , thereby avoiding excessive squeezing of the conductive rubber 104 and causing damage to the internal structure, thereby ensuring the service life during subsequent use.

[0050] like Figure 1-3 As shown, as a further explanation of the implementation method of the mechanical unlocking structure 4 in this embodiment, a rotating shaft 301 is provided in the retracting groove 3, the unlocking handle 2 is rotated on the rotating shaft 301, and an elastic element 302 is sleeved on the rotating shaft 301, one end of the elastic element abuts the base 1, and the other end abuts the unlocking handle 2, so that the unlocking handle 2 is retracted in the retracting groove 3, and the mechanical unlocking structure 4 includes an unlocking rope 303, the unlocking rope 303 is connected to the unlocking handle 2, and the unlocking handle 2 rotates outward, and pulls the unlocking rope 303 to perform mechanical unlocking.

[0051] When mechanical unlocking is required during use of the inner handle, the unlocking handle 2 can be pulled outward so that the unlocking handle 2 pulls the unlocking rope 303 to unlock, thereby realizing mechanical unlocking. After the mechanical unlocking is completed, the unlocking handle 2 will be retracted into the base 1 under the action of the elastic element 302.

[0052] Preferably, a shock-absorbing pad 304 is provided in the base 1. When the unlocking handle 2 is retracted into the base 1, the unlocking handle abuts against the shock-absorbing pad 304. When the mechanical unlocking is completed, the unlocking handle 2 rebounds under the action of the elastic element 302. The unlocking handle 2 will contact the shock-absorbing pad 304, reducing vibration and avoiding accidental touching of the electronic unlocking structure 5.

[0053] like Figure 1-6 As shown, the unlocking method of the inner handle by pressing the electronic unlocking to activate the mechanical unlocking includes the following steps:

[0054] S0 Unlock method selection: Choose mechanical unlocking or electronic unlocking. You can pull the unlocking handle 2 outwards for mechanical unlocking or press the unlocking handle 2 inwards for electronic unlocking.

[0055] S1 performs mechanical unlocking: Pull one end of the unlocking handle 2 outward to rotate it outward, and the other end of the unlocking handle 2 pulls the unlocking rope 303 to mechanically unlock. After unlocking is completed, the unlocking handle 2 is retracted into the base 1 under the action of the elastic element 302;

[0056] S2 performs electronic unlocking: press the unlock handle 2 inward to rotate the unlock handle 2 inward and squeeze the unlock button 103. The unlock button 103 slides in the mounting shell 101. The unlock handle 2 first enters the idling stroke. The unlock button 103 first abuts against the second protrusion 106. After the second protrusion 106 is compressed to a certain extent, the unlock button 103 abuts against the first protrusion 105, so that the first protrusion 105 drives the unlock control module 102 to start electronic unlocking. After unlocking is completed, when the hand is separated from the unlock handle 2, the unlock button 103 will push the unlock handle 2 back to the initial position.

[0057] This specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art may make non-creative modifications to this embodiment as needed. However, as long as such modifications are within the scope of the claims of the present invention, they are protected by patent law.
