Description

Technical Field

[0001] The present application relates to the technical field of automobile accessories, and in particular to an expansion device and an automobile. Background Art

[0002] To create a modern and technological feel, more and more automakers are removing physical buttons that previously performed related functions and integrating virtual buttons with the same functionality into the center console, resulting in a more streamlined system. However, virtual buttons leave fingerprints during operation, making them unsightly. Furthermore, due to the lack of feedback during driving, virtual buttons are inconvenient and unsafe to operate. Consequently, automakers are integrating the physical buttons that perform related functions into optional add-on devices for users.

[0003] In the related art, the expansion module of the expansion device is not convenient enough to be assembled and disassembled. Utility Model Content

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes an expansion device and a vehicle to improve the convenience of disassembling and assembling the expansion module.

[0005] An expansion device according to an embodiment of the first aspect of the present application includes:

[0006] Extension modules;

[0007] A connector assembly comprising an inner housing, a locking member, and a driving member, wherein the inner housing is connected to the expansion module, and the driving member is movable within the inner housing along a first direction to drive the locking member to move relative to the inner housing along a second direction between a first position and a second position. When the locking member is in the first position, the locking member is recessed in the inner housing, and when the locking member is in the second position, the locking member protrudes from the inner housing, and the second direction is arranged to intersect the first direction.

[0008] A fixing assembly includes a shell having a locking portion, and at least a portion of the connector assembly is arranged in the shell. When the locking member is in the first position, the connector assembly can move relative to the fixing assembly to disengage from the shell. When the locking member is in the second position, the locking member can lock with the locking portion to lock the connector assembly to the fixing assembly.

[0009] The expansion device according to the embodiment of the present application has at least the following beneficial effects:

[0010] In an embodiment of the present application, a driver drives a locking member to move relative to the inner housing in a second direction, such that the locking member has a first position recessed into the inner housing and a second position protruding from the inner housing. When the locking member is in the first position relative to the inner housing, the locking member disengages from the locking portion of the outer housing, allowing the connector assembly to move relative to the outer housing of the fixed assembly to separate from the outer housing. When the locking member is in the second position relative to the inner housing, the locking member engages with the locking portion of the outer housing to lock the connector assembly within the outer housing of the fixed assembly. By operating the driver to drive the locking member relative to the inner housing, the connector assembly can be disengaged from the fixed assembly or locked to the fixed assembly. This allows for convenient assembly and disassembly of the expansion module without the need for screws and related tools, improving ease of assembly and disassembly of the expansion module and reducing the possibility of screws falling into gaps in the central control assembly. Because the fixed assembly can be positioned at a predetermined position in the central control assembly based on user preferences and habits, it facilitates personalized user needs and enhances the user experience.

[0011] According to some embodiments of the present application, the movement direction of the driving member driving the locking member to switch from the second position to the first position is the same as the movement direction of the connector assembly to separate from the housing assembly.

[0013] When the locking member is located at the first position, the locking member abuts against the plane; when the locking member is located at the second position, the locking member abuts against the locking surface.

[0014] According to some embodiments of the present application, the locking surface includes a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are arranged in sequence along the moving direction of the connector assembly from the housing. The slope of the first inclined surface is greater than the slope of the second inclined surface. When the locking member is in the second position, the locking member abuts against the first inclined surface, or, when the locking member is in the second position, the locking member abuts against the second inclined surface.

[0015] According to some embodiments of the present application, the number of the locking members is at least two, at least two of the locking members are arranged at intervals along the first direction, and the locking portions correspond one-to-one to the locking members.

[0016] According to some embodiments of the present application, there are multiple protrusions, and the connector assembly includes an elastic member, which is arranged in the inner shell. One end of the elastic member along the first direction is connected to the driving member, and the other end of the elastic member is connected to the inner shell. The elastic member is configured so that the driving member has a tendency to drive the locking member to lock with the locking portion.

[0017] According to some embodiments of the present application, the connector assembly includes a first magnetic component, which is arranged at an end of the inner shell away from the expansion module along the first direction, and the fixing assembly includes a second magnetic component, which is arranged at an end of the outer shell away from the expansion module along the first direction, so that the first magnetic component can be magnetically matched with the second magnetic component.

[0034] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0035] In the description of this application, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or workstation relationships, are based on the orientations or workstation relationships shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application.

[0036] In the description of this application, "several" means more than one, "plurality" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0037] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0038] In the description of this application, reference to the terms "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in any appropriate manner in any one or more embodiments or examples.

[0039] In the prior art, expansion devices are typically connected to the central control assembly using screws. This requires tools for both installation and removal, making installation and removal inconvenient. The screws used to install the expansion device can easily slip and fall into gaps in the central control assembly, making it difficult to remove. Furthermore, because the expansion device is connected to the central control assembly using screws, it is typically only secured to a specific location within the central control assembly, making it difficult for users to adjust the position of the expansion device to their preferences.

[0040] In view of this, an embodiment of the present application provides an expansion device 100 in which a driving member 23 drives a locking member 22 to move relative to an inner housing 21, such that the locking member 22 has a first position recessed in the inner housing 21 and a second position protruding from the inner housing 21. When the locking member 22 is in the first position relative to the inner housing 21, the connector assembly 2 can move relative to the outer housing 31 of the fixed assembly 3 to detach from the outer housing 31. When the locking member 22 is in the second position relative to the inner housing 21, the locking member 22 can engage with a locking portion 311 of the outer housing 31 to lock the connector assembly 2 within the outer housing 31 of the fixed assembly 3. By driving the locking member 22 relative to the inner housing 21 by the driving member 23, the connector assembly 2 can be detached from the fixed assembly 3 or locked to the fixed assembly 3. This allows for convenient assembly and disassembly of the expansion module 1 without the need for screws and related tools, reducing the possibility of screws falling into gaps in the central control assembly 200.

[0041] Specifically, see Figure 7 , an embodiment of the present application provides an automobile, including a central control assembly 200 and an expansion device 100. The central control assembly 200 may include a central control body 201 and a display device 202. The display device 202 is arranged on the central control body 201 and electrically connected to the central control body 201, so as to realize relevant functions of the automobile through virtual buttons on the display device 202, such as turning on and off the air conditioner, adjusting the volume of the speaker, etc. The expansion device 100 is installed on the central control assembly 200 and electrically connected to the central control body 201, so as to replace the virtual buttons integrated in the display device 202 to realize relevant functions of the automobile. The expansion device 100 has a relatively fixed position and a certain touch feedback relative to the virtual buttons in the display device 202, which is convenient for users to turn on and off relevant functions of the automobile more quickly according to their own muscle memory, thereby improving the safety of the automobile during driving.

[0042] See also Figure 1 and Figure 4 The expansion device 100 includes an expansion module 1, a connector component 2, and a fixing component 3. The expansion module 1 can be a physical button to replace the virtual button on the display device 202 to implement the relevant functions of the car. The expansion module 1 can also be an external speaker or an external storage box to meet the personalized needs of users. Figure 2 and Figure 5 The connector assembly 2 includes an inner shell 21, a locking member 22, and a driving member 23. The inner shell 21 can be made of metal or a material with a certain strength. The inner shell 21 is connected to the expansion module 1 so that the expansion module 1 can be set on the fixed assembly 3 through the connector assembly 2. The driving member 23 can move in the inner shell 21 along a first direction to drive the locking member 22 to move relative to the inner shell 21 along a second direction between a first position and a second position. For example, Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The direction shown by R1 is the first direction, Figure 2 and Figure 5 The direction indicated by R2 is the second direction, the first direction and the second direction are arranged crosswise, and the first direction can also be arranged perpendicular to the second direction. Specifically, Figure 2 The assembly process of the connector assembly 2 and the fixing assembly 3 is shown. Figure 2 As shown, when the locking member 22 is located at the first position, the locking member 22 is recessed into the inner housing 21 . Figure 5 It shows that the connector assembly 2 and the fixing assembly 3 have been assembled in place. Figure 5 As shown, when the locking member 22 is located at the second position, the locking member 22 protrudes from the inner housing 21 .

[0043] For example, see Figure 2 and Figure 5The upper surface of the inner shell 21 has an avoidance hole 213 for avoiding the locking member 22. When the locking member 22 is in the first position, the upper end of the locking member 22 is recessed in the avoidance hole 213. When the locking member 22 is in the second position, the upper end of the locking member 22 protrudes from the avoidance hole 213.

[0044] For example, see Figure 3 and Figure 6 The inner shell 21 may include a shell 211 and a fixing bracket 212. The fixing bracket 212 is arranged in the shell 211. The fixing bracket 212 and the shell 211 jointly enclose an avoidance hole 213, so that when the driving member 23 moves along the first direction in the inner shell 21 to drive the locking member 22 to switch between the first position and the second position relative to the inner shell 21 along the second direction, the fixing bracket 212 can limit the movement of the locking member 22 in the first direction, so that the locking member 22 can only move along the second direction.

[0045] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The fixing assembly 3 includes a housing 31, and at least part of the connector assembly 2 is disposed in the housing 31. The housing 31 has a locking portion 311. When the locking member 22 is in the second position, the locking member 22 can lock with the locking portion 311 to lock the connector assembly 2 to the fixing assembly 3. For example, the locking portion 311 of the housing 31 can be as follows: Figure 2 and Figure 5 The locking hole shown penetrates the surface of the outer shell 31 along the second direction. The locking portion 311 can also be a locking groove, with the opening direction of the locking groove being in the second direction toward the direction of the connector assembly 2, so that the portion of the locking member 22 protruding from the inner shell 21 along the second direction can be snapped into the locking hole or locking groove, thereby locking the connector assembly 2 with the fixed assembly 3. The operating drive member 23 drives the locking member 22, so that when the locking member 22 is in the first position, the locking member 22 disengages from the locking portion 311, thereby allowing the connector assembly 2 to move relative to the fixed assembly 3 in the first direction to separate from the outer shell 31.

[0046] In the embodiment of the present application, the locking member 22 is driven by the driving member 23 to move relative to the inner shell 21 along the second direction, so that the locking member 22 has a first position recessed in the inner shell 21 and a second position protruding from the inner shell 21. When the locking member 22 is in the first position relative to the inner shell 21, the locking member 22 can be disengaged from the locking portion 311 of the outer shell 31, so that the connector assembly 2 can move relative to the outer shell 31 of the fixed assembly 3 to disengage from the outer shell 31. When the locking member 22 is in the second position relative to the inner shell 21, the locking member 22 can be locked with the locking portion 311 of the outer shell 31 to lock the connector assembly 2 in the outer shell 31 of the fixed assembly 3. By operating the driver 23 to move the locking member 22 relative to the inner housing 21, the connector assembly 2 can be disengaged from the fixing member 3 or locked to the fixing member 3. This allows for convenient assembly and disassembly of the expansion module 1 without the need for screws or related tools, improving the ease of assembly and disassembly of the expansion module 1 and reducing the possibility of screws falling into gaps in the central control assembly 200. Because the fixing member 3 can be set at a preset position in the central control assembly 200 based on the user's preferences and habits, it helps meet the user's personalized needs and, in turn, improves the user experience.

[0047] In one embodiment, please refer to Figure 2 and Figure 5 The movement direction of the driving member 23 driving the locking member 22 to switch from the second position to the first position is the same as the movement direction of the connector component 2 to separate from the housing 31 component, so that during the process of disassembling the connector component 2, the connector component 2 can be disassembled from the fixing component 3 more conveniently.

[0048] For example, see Figure 2 and Figure 5 The end of the driving member 23 that is closer to the expansion module 1 along the first direction has an operating portion 232. This allows the user to move the driving member 23 relative to the inner housing 21 in the first direction via the operating portion 232. When the driving member 23 moves along the first direction toward the expansion module 1, it drives the locking member 22 from the second position to the first position, disengaging the locking member 22 from the locking portion 311. This allows the connector assembly 2 to also disengage from the fixing assembly 3 along the first direction toward the expansion module 1. The movement direction of the driving member 23 is the same as the disengagement direction of the connector assembly 2, facilitating removal of the expansion module 1.

[0049] It is understandable that the moving direction of the driving member 23 is not limited to being in the same direction as the disengagement direction of the connector assembly 2. For example, the moving direction of the driving member 23 may also be opposite to the disengagement direction of the connector assembly 2.

[0050] In one embodiment, please refer to Figure 3 and Figure 6The driving member 23 has a driving surface 231, which includes a plane 2311 and a locking surface 2312 connected to each other. The plane 2311 is generally parallel to the first direction and is arranged in sequence along the direction of movement of the connector assembly 2 from the housing 31. The locking surface 2312 can be located on the side of the plane 2311 closer to the expansion module 1 along the first direction, or on the side of the plane 2311 away from the expansion module 1 along the first direction. The distance between the locking surface 2312 and the locking portion 311 gradually decreases. The locking surface 2312 can be an inclined surface or a curved surface. When the locking member 22 is in the first position, the locking member 22 abuts the plane 2311. When the locking member 22 is in the second position, the locking member 22 abuts the locking surface 2312.

[0051] For example, the locking member 22 may be a ball bearing, which facilitates the driving member 23 to move in the first direction relative to the locking member 22 . The driving member 23 may be made of metal or a material with a certain strength.

[0052] For example, see Figures 1 to 3 During the assembly of the connector assembly 2 and the fixing assembly 3, the driving member 23 is moved along the first direction toward the expansion module 1. The driving surface 231 moves relative to the locking member 22 along the first direction toward the expansion module 1. Under the action of gravity, the locking member 22 moves relative to the inner housing 21 along the second direction to the plane 2311, so that the locking member 22 is in the first position relative to the inner housing 21. Figures 4 to 6 When the connector assembly 2 and the fixing assembly 3 are assembled in place, the driving member 23 is moved along the first direction away from the expansion module 1, and the driving surface 231 moves relative to the locking member 22 along the first direction away from the expansion module 1. Under the pressure of the locking surface 2312, the locking member 22 can move to the second position relative to the inner shell 21 along the second direction, so that the end of the locking member 22 away from the driving member 23 along the second direction is locked with the locking portion 311 of the outer shell 31, so that the connector assembly 2 is more firmly set in the fixing assembly 3.

[0053] In the embodiment of the present application, the plane 2311 and the locking surface 2312 are connected to each other, so that the movement of the driving member 23 along the first direction can drive the locking member 22 to move between the first position and the second position along the second direction. The structure is relatively simple and the operation is relatively convenient, which is conducive to improving the convenience of disassembly and assembly of the expansion module 1.

[0054] In one embodiment, please refer to Figure 3 and Figure 6The locking surface 2312 includes a first inclined surface 23121 and a second inclined surface 23122. Along the moving direction of the connector assembly 2 from the housing 31, the first inclined surface 23121 and the second inclined surface 23122 are arranged in sequence. The first inclined surface 23121 is located along the first direction on the side of the second inclined surface 23122 away from the expansion module 1. The slope of the first inclined surface 23121 is greater than the slope of the second inclined surface 23122. When the locking member 22 is in the second position, the locking member 22 abuts against the first inclined surface 23121, or when the locking member 22 is in the second position, the locking member 22 abuts against the second inclined surface 23122, so that when the driving member 23 moves along the first direction toward the direction away from the expansion module 1, the slope The first inclined surface 23121 with a larger slope can drive the locking member 22 to move in the second direction at a faster speed, which is convenient for timely locking the locking member 22 with the locking portion 311. The second inclined surface 23122 with a smaller slope can drive the locking member 22 to continue to move in the second direction at a slower speed, which is convenient for fine-tuning the position of the locking member 22 relative to the inner shell 21 along the second direction and locking the locking member 22 with the locking portion 311 more tightly, which is beneficial to reducing the possibility of the expansion module 1 shaking in the second direction due to the assembly gap between the connector component 2 and the fixing component 3, and then helping to improve the user experience and reduce the possibility of electrical connection failure between the connector component 2 and the fixing component 3.

[0055] It is understood that the magnitude relationship between the slope of the first inclined surface 23121 and the slope of the second inclined surface 23122 is not limited. For example, the slope of the first inclined surface 23121 can also be less than or equal to the slope of the second inclined surface 23122.

[0056] In one embodiment, please refer to Figures 1 to 6 There are at least two locking members 22, and the at least two locking members 22 are spaced apart along the first direction, with the locking portions 311 corresponding one to one with the locking members 22. When the at least two locking members 22 are both in the second position, the at least two locking members 22 can be locked with the corresponding number of locking portions 311, thereby increasing the restraining area of the fixing assembly 3 with respect to the plug assembly 2. This helps reduce the possibility of the expansion module 1 shaking in a direction intersecting both the first and second directions due to the assembly gap between the plug assembly 2 and the fixing assembly 3, thereby improving the user experience and reducing the possibility of electrical connection failure between the plug assembly 2 and the fixing assembly 3.

[0057] In one embodiment, please refer to Figure 2 and Figure 5The connector assembly 2 includes an elastic member 24, which is arranged in the inner shell 21. One end of the elastic member 24 along the first direction is connected to the driving member 23, and the other end of the elastic member 24 is connected to the inner shell 21. The elastic member 24 is configured so that the driving member 23 has a tendency to drive the locking member 22 to lock with the locking portion 311, so that when the connector assembly 2 and the fixing assembly 3 are assembled in place and the locking member 22 is in the second position and locked with the locking portion 311, the driving member 23 is less likely to move along the first direction toward the expansion assembly, thereby reducing the possibility of the locking member 22 being disengaged from the locking portion 311, so as to improve the stability of the connection between the connector assembly 2 and the fixing assembly 3.

[0058] Exemplarily, the elastic member 24 can be a spring. When the connector assembly 2 and the fixing assembly 3 are assembled in place and the locking member 22 is in the second position and locked with the locking portion 311, the elastic member 24 can be in a balanced state or in a compressed state, so that the elastic member 24 applies a force to the driving member 23 along the first direction toward away from the expansion module 1 to maintain the locking member 22 in the second position, thereby reducing the possibility of the locking member 22 being detached from the locking portion 311.

[0059] It is understandable that the connector assembly 2 is not limited to including the elastic member 24. For example, a protrusion can be provided on the driving member 23, and a first groove and a second groove that engage with the protrusion can be provided on the inner housing 21. When the protrusion is engaged with the first groove, the locking member 22 is located in the first position, and when the protrusion is engaged with the second groove, the locking member 22 is located in the second position.

[0060] In one embodiment, please refer to Figure 2 and Figure 5 The connector assembly 2 includes a first magnetic member 25, which can be a magnet or a metal that can be attracted to a magnet. The first magnetic member 25 is disposed along the first direction at the end of the inner shell 21 that faces away from the expansion module 1. The fixing assembly 3 includes a second magnetic member 33, which can be a magnet or a metal that can be attracted to a magnet. The second magnetic member 33 is disposed along the first direction at the end of the outer shell 31 that faces away from the expansion module 1, so that the first magnetic member 25 can magnetically cooperate with the second magnetic member 33. On the one hand, during the assembly of the connector component 2 and the fixed component 3, the first magnetic component 25 gradually approaches the second magnetic component 33 along the first direction, and the magnetic attraction between the first magnetic component 25 and the second magnetic component 33 gradually increases. When the first magnetic component 25 and the second magnetic component 33 are magnetically engaged, it can indicate that the connector component 2 and the fixed component 3 are assembled in place, which is beneficial to improving the convenience of users to install the expansion module 1; on the other hand, the magnetic attraction between the first magnetic component 25 and the second magnetic component 33 can connect the connector component 2 and the fixed component 3 more tightly to reduce the possibility of the connector component 2 and the fixed component 3 being detached.

[0061] It is understandable that the connector assembly 2 is not limited to including the first magnetic member 25 , and the fixing assembly 3 is not limited to including the second magnetic member 33 .

[0062] In one embodiment, please refer to Figure 7 The fixing component 3 is arranged on the side of the central control assembly 200 away from the cockpit of the car to reduce the space occupied in the cockpit, and the expansion module 1 is arranged on the side of the central control assembly 200 close to the cockpit to facilitate the user to operate the expansion module 1.

[0063] In one embodiment, please refer to Figure 2 、 Figure 5 and Figure 7 The central control assembly 200 has a mounting opening 203. The housing 31 has a receiving opening 312 on one side of the housing 31 along the first direction, proximate to the expansion module 1. The receiving opening 312 communicates with the mounting opening 203, allowing the side of the fixture with the receiving opening 312 to be connected to the central control assembly 200. The connector assembly 2 is at least partially slidably disposed within the housing 31 along the first direction, passing through the mounting opening 203 and the receiving opening 312.
