Description

Technical Field

[0001] This disclosure relates to the field of motor vehicle lock technology, and more particularly to a lock body mechanism, lock device, and automobile. Background Technology

[0002] A car tailgate is a type of tailgate that opens in two separate sections, top and bottom. With the development of automotive automation and intelligent technologies, the locking mechanism of car tailgates is gradually adopting electric and intelligent electromechanical systems.

[0003] Existing automotive tailgate lock mechanisms generally adopt a split structure, that is, components such as the latch are configured separately from components such as the electric closing actuator. For example, the lock for installation on a car tailgate disclosed in Chinese patent document CN201520060740.4 has an electric closing actuator that is difficult to integrate with the latch and pawl into a single unit configuration. The electric closing actuator needs to be configured separately. This configuration makes the lock mechanism occupy a large space and its operational stability needs to be improved.

[0004] Furthermore, with advancements in automotive technology, more and more vehicles are using suicide doors to enhance the user experience. However, these suicide doors present challenges in door lock placement because it's impossible to position the lock in the middle of the door's height. Placing a lock at the top or bottom of the door can result in the door failing to lock properly, compromising vehicle safety. Summary of the Invention

[0091] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0092] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0093] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0094] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0095] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0096] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations 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 “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0097] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, 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 rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0098] The following text is for reference only. Figures 1 to 5 The lock mechanism disclosed herein will be described in detail.

[0099] Figure 1 This is a schematic diagram of the structure of an automotive top and bottom door according to one embodiment of the present disclosure.

[0100] Figure 1 In the car, the Heaven and Earth Gate consists of the Heaven Gate and the Earth Gate. Both the Heaven Gate and the Earth Gate are mounted on the rear of the car body via rotating shafts, and the rotating axes of the Heaven Gate and the Earth Gate are parallel to each other.

[0101] The lock mechanism 100 disclosed herein can be used in, for example... Figure 1 The car's top and bottom doors are shown.

[0102] In some embodiments of this disclosure, the lock body mechanism is disposed on the vehicle body and is located above the rotation axis of the bottom door of the vehicle's top and bottom doors. It includes: a latch 101; a pawl 102; a first motor 103, which outputs a rotational drive action via a motor shaft (not shown); an unlocking actuator, which outputs an unlocking drive action to the pawl 102 based on the rotational drive action in a first direction output by the first motor 103, thereby releasing the pawl 102 from holding the latch 101 in a locked position (at least one locked position), allowing the latch 101 to move to the unlocked position; and a engaging actuator, which outputs an engaging drive action to the latch 101 based on the rotational drive action in a second direction opposite to the first direction output by the first motor 103, causing the latch 101 to move to the fully locked position.

[0103] The lock body mechanism 100 disclosed herein can realize both the unlocking and engaging functions through a single motor, namely the first motor 103. The lock tongue, pawl, first motor, unlocking actuator, and engaging actuator of the lock body mechanism 100 disclosed herein can be held by the same lock body housing 120.

[0104] Preferably, the unlocking actuator of this disclosure includes an unlocking lever 105, which can output an unlocking drive action to the pawl 102 based on the rotation drive action in the first direction output by the first motor 103.

[0105] Preferably, the engagement actuator of this disclosure includes: an engagement drive rod 106, which can output a rotation drive action based on the rotation drive action in the second direction output by the first motor 103; and an engagement lever 107, which can be driven by the rotation drive action output by the engagement drive rod 106 to output an engagement drive action on the latch 101.

[0106] Preferably, the lock body mechanism 100 of this disclosure further includes: a drive actuator, which outputs a linear drive action based on the rotation drive action output by the first motor 103 to drive the unlocking actuator and the engaging actuator.

[0107] The lock body mechanism 100 of this disclosure also includes a transmission mechanism, through which the rotational drive action of the first motor 103 is transmitted to the drive actuator.

[0108] In some other embodiments of this disclosure, reference is made to Figures 2 to 4The lock body mechanism 100 disclosed herein is disposed on the body of an automobile and is located above the rotation axis of the bottom door of the automobile's top and bottom door. It includes: a latch 101; a pawl 102; a first motor 103, which outputs a rotational drive action via a motor shaft (not shown); a nut screw drive mechanism 104 (drive actuator), which outputs a linear drive action based on the rotational drive action output by the first motor 103; and an unlocking lever 105 (unlocking actuator), which can be driven by a third-direction linear drive action output by the nut screw drive mechanism 104. The mechanism drives the pawl 102 to release it from the locking position (at least one locking position) of the bolt 101, allowing the bolt 101 to move to the unlocked position; it also drives the pull-in drive rod 106, which is driven by the linear drive action in the fourth direction opposite to the third direction output by the nut screw drive mechanism 104 to output a rotational drive action; and it also drives the pull-in lever 107, which is driven by the rotational drive action output by the pull-in drive rod 106 to output a pull-in drive action on the bolt 101, causing the bolt 101 to move to the fully locked position.

[0109] In this disclosure, the locking tongue 101 may have two locking positions, a first locking position and a second locking position (i.e., pre-locking position and full-locking position). When the full-locking position of the locking tongue 101 engages with the retaining structure of the pawl 102, the locking tongue 101 is in the fully locked position. The structure of the locking tongue 101 and the pawl 102 may adopt existing structures or make appropriate adjustments to existing structures, all of which fall within the protection scope of this disclosure.

[0110] In the preferred embodiments of this disclosure, the unlocking and engaging functions of the lock mechanism 100 can be achieved based on the driving action of the same first motor 103.

[0111] When the first motor 103 outputs a forward rotation drive action (or a reverse rotation drive action), the unlocking rod 105 of the lock body mechanism 100 is driven by the nut screw drive mechanism 104 to drive the pawl 102 and perform the unlocking function. When the first motor 103 outputs a reverse rotation drive action (or a forward rotation drive action), the engaging drive rod 106 of the lock body mechanism 100 is driven by the nut screw drive mechanism 104, thereby engaging the engaging drive rod 106 to drive the engaging lever 107, so that the engaging lever 107 outputs an engaging drive action to the locking tongue 101 and performs the engaging function.

[0112] Since the engaging actuator (engaging drive rod and engaging lever), unlocking rod 105, pawl 102 and nut screw drive mechanism 104 (drive actuator) need to be integrally configured on the lock body mechanism 100, this disclosure designs the mechanical structure of the engaging actuator. That is, through the cooperation of engaging drive rod 106 and engaging lever 107, the engaging drive action is realized through the rotational cooperation of the two, which can save the configuration space inside the housing of the lock body mechanism 100. Moreover, the engaging actuator of this disclosure can effectively and reliably perform the engaging function.

[0113] refer to Figure 4 In some embodiments of this disclosure, the nut screw drive mechanism of the lock body mechanism 100 includes a drive screw 1041 and a drive nut 1042. The drive nut 1042 is sleeved on the drive screw 1041 and can output linear drive motion based on the rotation of the drive screw 1041.

[0114] The drive screw 1041 can rotate based on the rotation action of the first motor 103. The surface of the drive screw 1041 is provided with threads. The drive nut 1042 has a hollow hole with threads inside. The drive nut 1042 can be sleeved on the drive screw 1041 based on the hollow hole, so that the two can be connected by transmission based on the threads.

[0115] The components disclosed herein, including the latch, pawl, lead screw drive mechanism, motor, unlocking lever, engaging drive lever, and engaging lever, are disposed within the lock body mechanism housing 120 of the lock body mechanism 100. The lock body mechanism housing 120 may include, for example, components such as... Figure 3 The mounting base 121, motor housing 123, connector housing 124, etc. shown can be modified by those skilled in the art based on the technical solutions of this disclosure. For example, the motor housing 123 can be detachably mounted on the mounting base 121, and the connector housing 124 can be detachably mounted on the mounting base 121. All of these modifications fall within the protection scope of this disclosure.

[0116] In some embodiments of this disclosure, a guide groove or similar structure may be provided on the inner wall of the lock body housing 120, and a protruding structure that cooperates with the guide groove may be provided on the outer side of the drive nut 1042, thereby restricting the rotation of the drive nut 1042 and realizing the linear motion of the drive nut 1042.

[0117] The nut and screw drive mechanism disclosed herein can adopt existing structures or make adjustments to existing structures, all of which fall within the protection scope of this disclosure.

[0118] refer to Figure 4In some embodiments of this disclosure, the attraction lever 107 described above is driven by the rotational drive action of the attraction drive rod 106 to rotate and thus output an attraction drive action.

[0119] refer to Figure 2 and Figure 4 In some embodiments of this disclosure, the suction drive rod 106 is mounted on the lock body mechanism 100 based on the suction drive rod shaft 1062, and the extension direction of the suction drive rod shaft 1062 is perpendicular to the rotation plane of the suction drive rod 106; the suction lever 107 is mounted on the lock body mechanism 100 based on the suction lever shaft (not shown), and the extension direction of the suction lever shaft is perpendicular to the rotation plane of the suction lever 107; wherein, the suction drive rod shaft 1062 and the suction lever shaft have a preset distance.

[0120] refer to Figure 4 Preferably, the attraction drive rod 106 of this disclosure includes: a first connecting end, the first connecting end 1061 being connected (pivotally connected) to the drive nut 1042 to receive the linear drive action of the drive nut 1042; a connecting structure for connecting to the first connecting end 1061 may be configured on the outer side of the drive nut 1042, which is not particularly limited in this disclosure; a second connecting end, the second connecting end being rotatably connected to the attraction drive rod shaft 1062, such that when the first connecting end 1061 is driven by the drive nut 1042, the attraction drive rod 106 rotates around the attraction drive rod shaft 1062 based on the second connecting end; and a drive end 1063, the drive end 1063 outputting a drive action to the attraction lever 107 based on the rotation of the attraction drive rod 106.

[0121] refer to Figure 4 The lines connecting the first connecting end 1061, the second connecting end, and the driving end 1063 of the attraction drive rod 106 of this disclosure form a triangle.

[0122] With the above structural design, when the first connecting end 1061 of the attraction drive rod 106 is as follows Figure 4 When driven downwards, the attraction drive rod 106 will rotate counterclockwise. Since the second connecting end of the attraction drive rod 106 (sleeved on the attraction drive rod shaft 1062) can only rotate, the driving end 1063 of the attraction drive rod 106 will apply a force to the attraction lever 107, causing the attraction lever 107 to rotate counterclockwise, thereby the attraction lever 107 outputs an attraction drive action to the locking tongue 101.

[0123] refer to Figure 2In a preferred embodiment of this disclosure, the suction lever 107 includes: a first connecting portion 1071 for rotatably connecting with the suction lever shaft; a force receiving portion 1072 for receiving the driving action of the driving end 1063 of the suction driving rod 106; and a suction end 1073 for outputting a suction driving action to the locking tongue 101 based on the driving action received by the force receiving portion 1072.

In some embodiments of this disclosure, one end of the pull-in lever spring 1074 is fixedly connected to the pull-in drive rod shaft 1062, and the other end is fixedly connected to the end of the pull-in lever 107 away from the pulling end 1073, which is located on both sides of the force-receiving part 1072 at the first connecting part 1071.

[0126] Preferably, refer to Figure 2 and Figure 4 The force-receiving portion 1072 of the suction lever 107 disclosed herein is located between the first connecting portion 1071 and the suction end 1073, and the force-receiving portion 1072 has an extension dimension in a direction perpendicular to the rotation plane of the suction lever 107 so as to cooperate with the driving end of the suction drive rod 106.

[0127] Preferably, refer to Figure 4 The drive end 1063 of the attraction drive rod 106 disclosed herein is concave in shape, so as to cooperate with the force receiving part 1072 of the attraction lever 107 and output drive action to the force receiving part 1072.

[0128] In some embodiments of this disclosure, reference is made to Figure 4 The locking tongue 101 of this disclosure is provided with a suction operation end 1011. The suction operation end 1011 can be operated by the suction drive action output by the suction end 1073 of the suction lever 107, so that the locking tongue 101 moves to the fully locked position.

[0129] The engaging end 1011 can be a structure extending from the latch 101 itself or a structure fixedly connected to the latch 101, both of which fall within the protection scope of this disclosure.

[0131] In some embodiments of this disclosure, the transmission mechanism of the lock body mechanism 100 described above includes a worm gear and a transmission gear 108. The worm gear is fixedly connected to the motor shaft of the first motor 103 to rotate coaxially with the motor shaft. The worm gear meshes with the transmission gear 108, which is fixed to one end of the drive screw 1041 to rotate coaxially with the drive screw 1041. The transmission mechanism consisting of the worm gear and the transmission gear is prior art. Any use of existing transmission mechanisms or structural adjustments thereof by those skilled in the art falls within the protection scope of this disclosure.

[0132] refer to Figure 5 , Figure 5 The overall structure of a lock body mechanism 100 according to one embodiment of the present disclosure is shown, as is the overall structure of the lock body mechanism housing 120.
