Description

Technical Field

[0001] The present disclosure relates to the technical fields of automotive child protection devices, door systems, etc. In particular, the present disclosure relates to a child protection device, a door system, and an automobile. Background Art

[0002] A child protection device, that is, a child insurance device (i.e., a child insurance mechanism), is an essential device on current automobiles.

[0003] For current child protection devices, an occupant (especially a rear occupant) needs to manually engage or disengage the insurance by operating a child protection button or a child protection knob installed on the inner side of the door, so as to disconnect or connect the power transmission between the door unlocking system (mechanical system and / or electric system) and the door lock.

[0004] However, in some scenarios, if there is only a child in the rear row or in some emergency situations, the rear occupant is inconvenient or unable to operate the child protection button or the child protection knob to disengage the child protection device, resulting in the door lock being unable to be unlocked, which will bring great inconvenience and even potential safety hazards. Summary of the Invention

[0005] According to one aspect of the present disclosure, there is provided a child protection device, including: An electric drive mechanism; A child protection execution part; A substrate, the electric drive mechanism is installed on a first side surface of the substrate, and the child protection execution part is installed on a second side surface of the substrate. The first side surface and the second side surface are two opposite surfaces of the substrate; The electric drive mechanism is connected to the child protection execution part via a first link. The electric drive mechanism can drive the child protection execution part via the first link, so that the child protection execution part moves to the child protection insurance-on state or the child protection insurance-off state.

[0006] For the child protection device according to at least one embodiment of the present disclosure, the child protection execution part includes: A child protection base, the child protection base is rotatably installed on the second side surface of the substrate; A child protection execution rod, the child protection execution rod is connected to the first link; A child protection execution shaft, the child protection execution shaft is arranged perpendicular to the child protection execution rod; The first link drives the child protection execution shaft by driving the child protection execution rod, so that the child protection execution shaft moves to a first position or a second position; when the child protection execution shaft moves to the first position, the child protection execution part moves to the child protection insurance-on state, and when the child protection execution shaft moves to the second position, the child protection execution part moves to the child protection insurance-off state.

[0007] According to the child protection device of at least one embodiment of the present disclosure, a first through groove is formed on the child protection execution rod, and the child protection execution shaft passes through the first through groove and can slide or roll within the first through groove.

[0008] According to the child protection device of at least one embodiment of the present disclosure, the child protection base is integrally formed with the child protection execution rod, or the child protection base is fixedly connected to the first end of the child protection execution rod.

[0009] According to the child protection device of at least one embodiment of the present disclosure, the electric drive mechanism includes: A motor that outputs a rotational motion via a motor output shaft; A commutation mechanism fixedly connected to the first end of the first link. The commutation mechanism receives the rotational motion output by the motor output shaft and outputs a commuted rotational motion, and the commuted rotational motion is used to drive the first link.

[0010] According to the child protection device of at least one embodiment of the present disclosure, the second end of the first link is connected to a first shaft portion fixed on the child protection execution rod. The first link drives the child protection execution rod via the first shaft portion based on its second end, so that the child protection execution portion moves to the child protection upper insurance state or the child protection release insurance state.

[0011] According to the child protection device of at least one embodiment of the present disclosure, a second through groove is formed at the second end of the first link, and the first shaft portion passes through the second through groove, so that the first link drives the child protection execution rod via the first shaft portion based on the second through groove.

[0012] According to the child protection device of at least one embodiment of the present disclosure, the child protection execution shaft also passes through a third through groove at the first end of a first transmission rod for locking / unlocking the car door and can roll or slide within the third through groove; When the child protection execution portion is in the child protection release insurance state, a second transmission rod for locking / unlocking the car door can drive the child protection execution shaft and drive the first transmission rod through the child protection execution shaft, so that the first transmission rod outputs an action for unlocking the car door lock; When the child protection execution portion is in the child protection upper insurance state, the second transmission rod cannot drive the child protection execution shaft, and thus cannot drive the first transmission rod.

[0013] According to the child protection device of at least one embodiment of the present disclosure, in the axial direction of the child protection execution shaft, that is, in the direction perpendicular to the substrate, the first link, the child protection execution rod, the first transmission rod, and the second transmission rod are arranged in sequence.

[0026] The present disclosure will be further described in detail below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the relevant content and do not limit the present disclosure. Additionally, it should be noted that for the sake of convenience of description, only the parts related to the present disclosure are shown in the drawings.

[0027] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments may be combined with each other. The technical solutions of the present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] Unless otherwise specified, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Thus, unless otherwise specified, the features of the various embodiments / examples may be additionally combined, separated, interchanged, and / or rearranged without departing from the technical concept of the present disclosure.

[0029] In the drawings, cross - hatching and / or shading are generally used to make the boundaries between adjacent components clear. Thus, unless stated otherwise, the presence or absence of cross - hatching or shading does not convey or imply any preference or requirement regarding the specific material, material properties, dimensions, proportions, commonality between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. Additionally, in the drawings, for clarity and / or descriptive purposes, the dimensions and relative dimensions of components may be exaggerated. When the exemplary embodiments can be implemented differently, the specific process sequences may be performed in an order different from that described. For example, two consecutively described processes may be performed substantially simultaneously or in an order opposite to that described. Further, the same reference numerals denote the same components.

[0030] When a component is referred to as being "on" or "above" another component, "connected to" or "coupled to" another component, the component can be directly on the other component, directly connected to or directly coupled to the other component, or there may be an intermediate component. However, when the component is referred to as being "directly on" another component, "directly connected to" or "directly coupled to" another component, there is no intermediate component. For this reason, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have an intermediate component.

[0031] For descriptive purposes, the present disclosure may use spatial relative terms such as "under", "below", "beneath", "lower", "above", "upper", "on", "higher", and "side (e.g., in "side wall")" to describe the relationship of one component to another (other) component as shown in the drawings. In addition to the orientation depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as "under" or "beneath" another component or feature will then be positioned "above" the other component or feature. Thus, the exemplary term "under" can encompass both the "above" and "under" orientations. Additionally, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations), and accordingly, the spatial relative descriptors used herein are to be interpreted accordingly.

[0032] The terms used herein are for the purpose of describing particular embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms. Additionally, when the terms "comprise" and / or "include" and their variants are used in this specification, it is stated that there are the stated features, integers, steps, operations, components, assemblies, and / or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, components, assemblies, and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about", and other similar terms are used as approximate terms and not as terms of degree, and thus are used to explain the inherent deviations of measured, calculated, and / or provided values that would be recognized by a person of ordinary skill in the art.

[0033] Figure 1 is a schematic configuration diagram on a substrate (i.e., mounting plate, door substrate) of an embodiment of the present disclosure, that is, a front view when an occupant observes inside the vehicle.

[0034] Figure 2 is Figure 1 a rear view of the schematic diagram shown.

The first side surface and the second side surface are two opposite surfaces of the substrate 300.

[0037] The electric drive mechanism 100 is connected to the child protection execution part 200 via a first connecting rod 400. The electric drive mechanism 100 can drive the child protection execution part 200 via the first connecting rod 400, so that the child protection execution part 200 moves to the child protection on-insurance state or the child protection off-insurance state.

[0038] Figure 1 The inner door handle 500 of the vehicle is also shown. The substrate 300 is fixedly mounted on the vehicle door (the vehicle door is not shown), and the inner door handle 500 of the vehicle is also fixedly mounted on the first side surface of the substrate 300. The vehicle occupant can open and close the vehicle door (sliding door) by operating the inner door handle 500 of the vehicle.

[0039] Figure 1 The area outlined by the dashed line in the figure does not show two first connecting rods 400, but is a schematic diagram of the first connecting rod 400 at two different positions.

It may only have a first transmission rod 801 and a second transmission rod 802. The child protection execution unit 200 cooperates with the first transmission rod 801 and the second transmission rod 802 to implement the child protection function. The first transmission rod and the second transmission rod will be described in detail below.

[0046] The present disclosure first describes the child protection execution unit 200 designed by the present disclosure in detail.

[0047] Figure 3 A structural schematic diagram of the child protection execution unit 200 is shown. Figure 3 The perspective of Figure 2 is the same as Figure 4 A structural schematic diagram of the child protection execution unit 200 is also shown. Figure 4 The perspective of Figure 3 is the rear perspective of Figure 5 A cooperation schematic diagram of the child protection execution unit 200 and the first link 400 is shown. Figure 5 The perspective of Figure 4 is the same as

[0048] Referring to Figures 3 to 5 , in a preferred embodiment of the present disclosure, the child protection execution unit 200 of the present disclosure includes: a child protection base 201, the child protection base 201 is rotatably mounted on the second side of the substrate 300; a child protection execution rod 202, the child protection execution rod 202 is connected to the first link 400; a child protection execution shaft 203, the child protection execution shaft 203 is disposed perpendicular to the child protection execution rod 202.

[0049] The first link 400 drives the child protection execution shaft 203 to move the child protection execution shaft 203 to a first position or a second position by driving the child protection execution rod 202; when the child protection execution shaft 203 moves to the first position, the child protection execution unit 200 moves to the child protection upper insurance state (see Figure 8 ), when the child protection execution shaft 203 moves to the second position, the child protection execution unit 200 moves to the child protection release insurance state (see Figure 7 ).

[0050] It can be seen that the child protection execution unit 200 designed by the present disclosure has a very simple structure, improves the reliability of the child protection execution unit, and occupies very little space.

[0051] Figures 3 to 5 The shapes of the child protection base 201, the child protection actuating rod 202, and the first connecting rod 400 shown are exemplary. Under the inspiration of the technical solution of the present disclosure, any adjustment to their shapes or structures by those skilled in the art falls within the protection scope of the present disclosure.

[0052] In some embodiments of the present disclosure, the child protection actuating rod 202 is connected to the first connecting rod 400 through a first shaft portion 205 fixed to its end.

[0053] Wherein, the axis of the first shaft portion 205 is parallel to the axis of the child protection actuating shaft 203.

[0054] Preferably, the connection between the first shaft portion 205 and the first connecting rod 400 is a rotatable connection, so that the first connecting rod 400 can drive the child protection actuating rod 202 through a rotational movement, enabling the child protection actuating rod 202 and the child protection base 201 to rotate together, and thus the child protection actuating rod 202 drives the child protection actuating shaft 203 to move to the first position or the second position described above.

[0055] In some embodiments of the present disclosure, continue to refer to Figures 3 to 5 , the child protection base 201 is integrally formed with the child protection actuating rod 202, or the child protection base 201 is fixedly connected to the first end of the child protection actuating rod 202.

[0056] The above-described first shaft portion 205 is provided at the second end of the child protection actuating rod 202.

[0057] Continue to refer to Figures 3 to 5 , preferably, a first through groove 204 is formed on the child protection actuating rod 202 of the present disclosure, and the child protection actuating shaft 203 passes through the first through groove 204 and can slide or roll within the first through groove 204.

[0058] As can be seen from Figures 3 to 5 , preferably, the extending direction of the first through groove 204 is the same as or substantially the same as the extending direction of the child protection actuating rod 202.

[0059] Figure 6 Shows the cooperation structure between the electric drive mechanism 100 and the first connecting rod 400 in an embodiment of the present disclosure.

[0060] Refer to Figure 6, preferably, the electric drive mechanism 100 of the present disclosure includes: a motor 101 that outputs a rotational motion via a motor output shaft 102; a commutation mechanism 103 fixedly connected to a first end of the first link 400, the commutation mechanism 103 receiving the rotational motion output by the motor output shaft 102 and outputting a commuted rotational motion, and the commuted rotational motion is used to drive the first link 400.

[0061] Preferably, the motor output shaft 102 is a worm, and the commutation mechanism 103 is a worm gear (or gear), and the tooth portion 1031 of the worm gear (or gear) meshes with the worm to receive the rotational motion output by the worm.

[0062] Reference Figure 6 , the axle 1032 of the worm gear (or gear) can be fixedly connected to the first end of the first link 400.

[0063] The worm gear (or gear) rotates under the drive of the worm, and drives the first link 400 to rotate or swing through the rotation of the axle 1032, so that the first link 400 drives the child protection actuator rod 202.

[0064] Continue to refer to Figure 6 , the second end of the first link 400 is connected to a first shaft portion 205 fixed on the child protection actuator rod 202, and the first link 400 drives the child protection actuator rod 202 based on its second end via the first shaft portion 205, so that the child protection actuator 200 moves to the child protection on-insurance state or the child protection off-insurance state.

[0065] Continue to refer to Figure 6 , preferably, a second through groove 402 is formed at the second end of the first link 400 of the present disclosure, and the first shaft portion 205 passes through the second through groove 402, so that the first link 400 drives the child protection actuator rod 202 based on the second through groove 402 via the first shaft portion 205.

[0066] Figure 7 And Figure 8 respectively show a schematic diagram of the child protection device of the present disclosure in the off-insurance state and a schematic diagram in the on-insurance state.

[0067] Reference Figure 8 , the motor output shaft 102 can drive the child protection actuator shaft 203 to a first position by outputting a rotational motion in a first direction (for example, clockwise direction), that is, the child protection device is in the on-insurance state.

[0068] Reference Figure 7, the motor output shaft 102 can drive the child protection execution shaft 203 to the second position by rotating in the second direction (e.g., counterclockwise direction) opposite to the first direction, that is, the child protection device is in the deactivated state.

[0069] Figure 7 and Figure 8 shows the first transmission rod 801 and the second transmission rod 802 for locking / unlocking the vehicle door lock. Figure 9 shows the structural schematic diagram of the child protection device in the activated state.

[0070] Refer to Figures 7 to 9 , the first transmission rod 801 can be driven by the second transmission rod 802 in the deactivated state of the child protection device, so that the first transmission rod 801 can directly drive, for example, the unlocking cable 803 to perform an unlocking operation on the vehicle door lock, or the first transmission rod 801 can also drive, for example, the unlocking cable 803 through other transmission rods or driving rods to perform an unlocking operation on the vehicle door lock (e.g., Figure 9 in, the two unlocking cables 803 can respectively perform unlocking operations on the front vehicle door lock and the rear vehicle door lock).

[0071] Figures 7 to 9 The structures of the first transmission rod and the second transmission rod shown in

[0072] The first transmission rod 801 and the second transmission rod 802 can rotate around the same axis.

[0073] Continue to refer to Figure 7 , when the child protection execution shaft 203 is driven to the second position shown in, for example, Figure 7 the second transmission rod 802 can transmit the driving action to the first transmission rod 801 via the child protection execution shaft 203, so that the first transmission rod 801 can transmit the driving action to, for example, the unlocking cable 803.

[0074] Continue to refer to Figure 8 , when the child protection execution shaft 203 is driven to the second position shown in, for example, Figure 8When in the first position shown, the child protection execution shaft 203 is out of the position area that the second transmission rod 802 can drive to, and the second transmission rod 802 cannot transmit the driving action to the first transmission rod 801, so that the first transmission rod 801 cannot transmit the driving action to, for example, the unlocking cable 803.

[0075] Continue to refer to Figures 7 to 9 , preferably, the child protection execution shaft 203 also passes through the third through groove 8011 at the first end of the first transmission rod 801 for locking / unlocking the vehicle door lock and can roll or slide within the third through groove 8011.

[0076] When the child protection execution part 200 is in the child protection insurance removal state, the second transmission rod 802 for locking / unlocking the vehicle door lock can drive the child protection execution shaft 203 and drive the first transmission rod 801 through the child protection execution shaft 203, so that the first transmission rod 801 outputs an action for unlocking the vehicle door lock; When the child protection execution part 200 is in the child protection insurance state, the second transmission rod 802 cannot drive the child protection execution shaft 203, and thus cannot drive the first transmission rod 801.

[0077] Refer to Figure 7 and Figure 8 . Preferably, in the axial direction of the child protection execution shaft 203, that is, in the direction perpendicular to the substrate 300, the first connecting rod 400, the child protection execution rod 202, the first transmission rod 801, and the second transmission rod 802 are arranged in sequence.

[0078] The child protection device of each embodiment provided by the present disclosure has the following technical effects.

[0079] 1. Space optimization and integrated design: By arranging the electric drive mechanism and the child protection execution part on two opposite sides of the substrate respectively and using the first connecting rod to achieve power transmission, the space occupied by the traditional mechanical linkage structure on the vehicle door is significantly reduced, especially suitable for scenarios with high requirements for internal space such as sliding doors.

[0080] 2. Automatic control and safety improvement: The electric drive mechanism replaces the traditional manual dial operation of child protection, and can remotely control the switching of the child protection state at any position in the vehicle (such as the front driver's seat), solving the problem that it is impossible to manually operate only when there are only child occupants in the back row or in case of emergency, and at the same time avoiding potential safety hazards caused by children's accidental touch.

[0081] 3. High-reliability transmission structure: The sliding / rolling fit design of the child protection execution rod with the first through groove and the child protection execution shaft simplifies the mechanical transmission path and reduces the risk of component wear.

[0082] In summary, the child protection device of the present disclosure overcomes the defects of traditional child protection devices, such as relying on manual operation, occupying a large space in the car door, and poor compatibility, and provides a more efficient, reliable, and intelligent solution for automotive child safety protection.

[0083] The present disclosure also provides a car door system (such as a sliding door system) including the child protection device of any one of the embodiments of the present disclosure.

[0084] The present disclosure also provides a vehicle including the car door system of any one of the embodiments of the present disclosure.
