[0002] The car child safety lock is an active safety device to ensure the safety of children riding in the car, preventing the danger of children accidentally opening the door from inside the car while the wheels are moving. When the child safety lock is locked, even if the central lock is electrically unlocked, the child safety device is still in the locked state, the door can only be opened from the outside, and the door handle inside the car temporarily loses its door opening function.

[0003] Most of the child lock structures in the prior art use a large number of components through a series of transmission methods, which eventually temporarily disable the door handle inside the vehicle from opening the door. However, these structures not only have poor integrated design effects, resulting in more overall space occupation, but also when any structure is damaged or stuck, the door handle inside the vehicle cannot be locked, thereby causing the risk of accidentally opening the door. Therefore, under the operation of a series of numerous components, not only is the noise generation increased, making the components prone to damage and resulting in frequent replacement, but it also affects the stability of the overall child lock structure when locking the door handle inside the vehicle.

[0034] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0035] like Figures 1 to 5 As shown, the utility model is a vehicle child lock structure assembly, comprising: a housing 1; an electric release swing arm 2 and an inner opening arm 3, which are rotatably arranged in the housing 1, the electric release swing arm 2 and the inner opening arm 3 are arranged on the same rotation axis, and when the electric release swing arm 2 rotates, it is used to push the external inner opening device to rotate, so as to realize the inner opening of the door; the end of the inner opening arm 3 away from its rotation axis is connected to the inner opening pull wire 4, and the inner opening pull wire 4 is used to pull the inner opening arm 3 to rotate relative to the housing 1; the inner opening clutch arm assembly 5, which has an inner opening position that can be switched between an unlocking position and a locking position in the housing 1. The clutch arm 50 is movably connected to the inner opening arm 3 and can rotate synchronously with the inner opening arm 3; the inner opening clutch arm 50 in the unlocking position can be movably pressed against the electric release swing arm 2 due to the pulling of the inner opening pull wire 4, so that the inner opening of the door can be achieved when the electric release swing arm 2 rotates; when the inner opening clutch arm assembly 5 drives the inner opening clutch arm 50 to switch to the locking position, the inner opening clutch arm 50 moves relative to the inner opening arm 3 to the periphery of the electric release swing arm 2, so that when the inner opening pull wire 4 is pulled, the inner opening clutch arm 50 idles and does not contact the electric release swing arm 2, so as to limit the inner opening of the door.

[0036] In this embodiment, the unlocking and locking functions of the interior door handle are mainly realized. Specifically, under normal circumstances, the inner opening clutch arm 50 is usually in Figure 2In the unlocked position shown, when the user pulls the door handle inside the vehicle, the inner opening cable 4 can be pulled to drive the inner opening arm 3 around its rotation axis (i.e. Figure 2 The left end position of the inner opening arm 3) along Figure 2 The inner clutch arm 50 in the unlocked position is clamped on the inner opening arm 3, and the end of the inner clutch arm 50 is movably pressed against the electric release swing arm 2. Therefore, the inner opening arm 3 rotates to drive the inner clutch arm 50 to rotate around its rotation center and push the electric release swing arm 2 along the unlocked position. Figure 2 The inner opening clutch arm 50 is rotated counterclockwise, and finally the inner opening device (not shown in the figure) is driven to realize the inner opening of the door (that is, the door opening function is realized in the car). When the child is riding in the car, the user can control the inner opening clutch arm 50 to start through the central control system, and then pull the inner opening clutch arm 50 to the position as shown in the figure. Figure 3 As shown in the locking position, it can be seen that at this time, the end of the inner opening clutch arm 50 is at the periphery of the electric release swing arm 2. When the user pulls the inner door handle again, even if the inner opening arm 3 still drives the inner opening clutch arm 50 along Figure 3 The inner opening clutch arm 50 rotates counterclockwise, but at this time, the inner opening clutch arm 50 is in an idling state (i.e., it cannot contact the electric release swing arm 2). In the case where the electric release swing arm 2 cannot apply a rotational force, the inner opening device cannot realize the door opening function. Therefore, the child lock structure not only simplifies the overall structure, reduces the manufacturing cost, and saves the space occupied by the child lock structure in the door by integrating the electric release swing arm 2, the inner opening clutch arm 50, and the inner opening arm 3, but also can utilize the inner opening arm 3 in the locked position and the electric release swing arm 2 to be staggered, effectively ensuring the stability when the door opening function is lost when the inner door handle is pulled, thereby providing a guarantee for the safety of children when riding in the car.

[0037] The inner clutch arm assembly 5 also includes: a driving member 51, which is arranged in the housing 1, and the driving end of the driving member 51 is coaxially connected to the worm 52; a worm wheel 53 and a swing arm 54, the worm wheel 53 is rotatably arranged in the housing 1 and movably meshed with the worm 52; one end of the swing arm 54 is connected to the worm wheel 53, and the other end is movably engaged with the inner clutch arm 50.

[0038] like Figure 2 and Figure 3 As shown, when the driving member 51 is turned on and drives the coaxially connected worm 52 to rotate, the worm 52 can drive the worm wheel 53 movably meshed with it to rotate during the rotation process, thereby Figure 2 The swing arm 54 is shown moved to Figure 3 At the position shown, the inner opening clutch arm 50 connected to the end of the swing arm 54 is finally moved from the unlocking position relative to the inner opening arm 3 to Figure 3In the locking position shown, the structure is relatively simple as a whole, which reduces the use of parts and effectively ensures the smoothness and stability of the inner clutch arm 50 when switching between the unlocking position and the locking position. At the same time, the structure utilizes the self-locking characteristics of the worm wheel 53 and the worm 52 to provide stability for the inner clutch arm 50 when it is in the unlocking position and the locking position.

[0039] A first waist-shaped hole 30 is provided at the end of the inner opening arm 3 away from the inner opening pull wire 4, and a second waist-shaped hole 540 is provided at the end of the swing arm 54 away from the worm gear 53. Buckle parts 500 are formed at both ends of the inner opening clutch arm 50. The buckle parts 500 pass through the first waist-shaped hole 30 or the second waist-shaped hole 540 and are movably pressed against the inner opening clutch arm 50 or the swing arm 54.

[0040] like Figures 2 to 4 As shown, no matter it is the waist-shaped hole set on the inner opening arm 3 or the swing arm 54, when the buckle part 500 on the inner opening clutch arm 50 is movably engaged in the waist-shaped hole, the waist-shaped hole can provide convenience for the installation and disassembly of the inner opening clutch arm 50, and at the same time, it can effectively avoid the jamming phenomenon of the inner opening clutch arm 50 when it rotates with the inner opening arm 3 through the first waist-shaped hole 30 and the second waist-shaped hole 540, ensuring that the inner opening clutch arm 50 in the unlocked position can smoothly push the electric release swing arm 2 through the buckle part 500 to realize the door opening function.

[0041] It should be noted that the rotation center of the electric release swing arm 2 (not shown in the figure) is the rotation center of the inner opening arm 3, and the inner opening arm 3 drives the inner opening clutch arm 50 to rotate. Figure 2 The displayed position switches to Figure 3 In the position shown, the waist-shaped hole can also provide space for the inner opening clutch arm 50 to rotate relative to the swing arm 54, ensuring that the user can normally pull the inner door handle while the door is in a state of temporarily losing the opening function.

[0042] Preferably, if Figure 4 As shown, the buckle portion 500 in the present scheme consists of two parts: a guide portion 500a and an anti-slip portion 500b, wherein the guide portion 500a can pass through the above-mentioned first waist-shaped hole 30 or the second waist-shaped hole 540, so that the anti-slip portion 500b located at the end of the guide portion 500a can be pressed against the outer wall of the inner opening arm 3 or the swing arm 54, and the guide portion 500a plays a guiding and limiting effect on the movement of the inner opening clutch arm 50, and at the same time, the anti-slip portion 500b can be used to effectively prevent the inner opening clutch arm 50 from falling off during the movement, thereby improving the stability of the structure during operation.

[0043] An arc-shaped guide portion 20 is formed at the periphery of the electric release swing arm 2, and an extension portion 502 is formed at the end of the inner opening clutch arm 50 away from the swing arm 54. The extension portion 502 and the buckle portion 500 have opposite buckling directions, and the extension portion 502 is pressed against the bottom wall of the inner opening arm 3, and the buckle portion 500 is pressed against the top wall of the inner opening and movably pressed against the arc-shaped guide portion 20.

[0044] Further, if Figures 2 to 4 As shown, the buckle portion 500 of the inner opening clutch arm 50 in the unlocked position is located at the end of the arc-shaped guide portion 20. Since the electric release swing arm 2 and the inner opening arm 3 are arranged on the same rotation axis, the extension portion 502 at the end of the inner opening clutch arm 50 cooperates with the anti-detachment portion 500b of the buckle portion 500 to effectively ensure the stability of the buckle portion 500 and the inner opening arm 3 when they are movably engaged. Figure 2 and Figure 4 As shown, the extension portion 502 and the anti-slip portion 500b are oriented in opposite directions, and are distributed on both sides of the length direction of the first waist-shaped hole 30 during the clamping process, which plays a certain limiting effect. At this time, the guide portion 500a also happens to be movably pressed against the end of the arc-shaped guide portion 20. As the inner opening arm 3 rotates, the stability of the arc-shaped guide portion 20 when the inner opening clutch arm 50 rotates synchronously is guaranteed. In addition, the design of the guide portion 500a being movably pressed against the raised arc-shaped guide portion 20 also effectively avoids the stability of the inner opening device driven by the electric release swing arm 2 being affected.

[0045] An extension block 530 is provided at the periphery of the worm wheel 53 , a first connection portion 531 is formed on the extension block 530 , a second connection portion 541 is formed at the end of the swing arm 54 away from the inner clutch arm 50 , and the second connection portion 541 is movably sleeved on the first connection portion 531 .

[0046] like Figure 2 , Figure 3 as well as Figure 5 As shown, for the installation between the worm wheel 53 and the swing arm 54, this solution adopts the method of movably sleeved on the first connection part 531, which provides convenience for the connection between the extension block 530 and the swing arm 54, and further provides guarantee for the subsequent maintenance and replacement of parts. This structure is relatively simple, and while realizing the rapid connection between the worm wheel 53 and the swing arm 54, it also ensures the stability of the swing arm 54 during the swinging process driven by the rotation of the worm wheel 53, and avoids the displacement of the swing arm 54 relative to the worm wheel 53, which affects the smoothness and stability of the inner opening clutch arm 50 when switching between the locked position and the unlocked position.

[0047] A positioning block 531a and a limiting block 531b are provided on the first connection portion 531, and the limiting block 531b is connected to the outer wall of the positioning block 531a. A positioning hole 541a and a limiting hole 541b are provided on the second connection portion 541, and the limiting hole 541b is connected to the positioning hole 541a. The positioning hole 541a can be movably mounted on the positioning block 531a, so that the limiting block 531b extends into the limiting hole 541b to limit the relative rotation between the swing arm 54 and the extension block 530.

[0048] Further, if Figure 5 As shown, during the installation process, the worker can align the positioning block 531a with the positioning hole 541a. Similarly, after the limiting hole 541b is aligned with the limiting block 531b, the positioning block 531a can be inserted into the positioning hole 541a, and the limiting block 531b at this time also extends into the limiting hole 541b, so as to achieve the positioning installation between the first connecting part 531 and the second connecting part 541, effectively ensuring the stability between the swing arm 54 and the worm gear 53, and providing a guarantee for the accuracy and stability of the inner clutch arm 50 when switching between the unlocking position and the locking position. It should be added that when the first connecting part 531 and the second connecting part 541 are movably connected, the present solution can use the limiting structure (not shown in the figure) inside the housing 1 to ensure the stability of the two after the connection, which plays a certain limiting effect.

[0049] A mounting post 10 is provided in the housing 1 , a first torsion spring 100 is provided on the mounting post 10 , a clearance hole 31 is formed on the inner opening arm 3 , one end of the first torsion spring 100 is connected to the clearance hole 31 , and the other end is connected in the housing 1 .

[0050] like Figures 2 to 4 As shown, for the automatic reset of the inner opening arm 3, when the user no longer pulls the inner and outer pull wires, the elastic reset function of the first torsion spring 100 can be used to pull the inner opening arm 3 to rotate around its rotation center to Figure 2 or Figure 3 At the position shown, the structure is relatively simple as a whole, and is convenient and quick to install, and has good stability. It is worth noting that the first torsion spring 100 in this solution is movably connected to the clearance hole 31 of the inner opening arm 3, and the clearance hole 31 provides displacement space for the inner opening arm 3 when rotating relative to the housing 1, ensuring that the inner opening arm 3 can smoothly push the inner opening clutch arm 50 to rotate synchronously, and the first torsion spring 100 also ensures the accuracy of the inner opening arm 3 when rotating and resetting.

[0051] A fixing column 11 is also provided on the housing 1 , and a second torsion spring 110 is provided on the fixing column 11 . A protrusion 501 is formed at the end of the inner clutch arm 50 close to the swing arm 54 . One end of the second torsion spring 110 is connected to the housing 1 , and the other end is connected to the protrusion 501 .

[0052] like Figures 2 to 5 As shown, when the driving member 51 rotates forward, the inner clutch arm 50 can be pulled from the inner clutch arm 50 through the second waist-shaped hole 540 on the swing arm 54. Figure 2 The displayed position switches to Figure 3 At this time, the door handle in the vehicle temporarily loses the door opening function, and when the driving member 51 reverses, the swing arm 54 can be Figure 3 The displayed position switches to Figure 2 In this process, the second waist-shaped hole 540 cannot stably apply the force for resetting the inner clutch arm 50. At this time, the elastic resetting function of the second torsion spring 110 can be relied on to accurately reset the inner clutch arm 50 to the position along with the resetting of the swing arm 54. Figure 2 At the position shown, therefore, this solution utilizes the reverse rotation of the driving member 51 to drive the swing arm 54 to reset, and cooperates with the reset function of the second torsion spring 110 itself, which greatly improves the stability and accuracy of the inner clutch arm 50 when resetting.

[0053] Preferably, a detection switch 12 is also provided in the housing 1 in this solution. Figure 2 and Figure 3 As shown, the contact head of the detection switch 12 is movably pressed against the end of the inner opening arm 3 away from the rotation axis (i.e., the right end of the inner opening arm 3), and the detection switch 12 is used to give the central control panel an electrical signal that the structure of the child stroller is in a state of being able to be opened normally, so as to remind the user to switch the inner opening clutch arm 50 to the locking position (i.e., the locking position) when the child is riding in the stroller. Figure 3 shown in the position).

[0054] A reset stopper 13 is further provided in the housing 1 , and a limiting groove 32 is formed on the inner opening arm 3 , and the limiting groove 32 movably abuts against the reset stopper 13 , so that the inner opening arm 3 after reset can contact the detection switch 12 .

[0055] Further, if Figure 3 As shown, when the inner opening arm 3 is reset by the above-mentioned first torsion spring 100, the limiting function of the inner opening arm 3 can be realized through the cooperation of the reset block 13 on the shell 1 and the limiting groove 32, so that the end of the inner opening arm 3 after reset can accurately contact the above-mentioned detection switch 12, and then give the user an electrical signal of the state of the child lock structure.

[0056] It should be noted that the driving member 51 in this solution can be replaced by other driving devices such as a stepper motor and a servo motor. In addition, the inner opening device in this solution can adopt the structure in the prior art, and its working principle and structure are the same, which will not be repeated here.

[0057] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0058] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0059] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
