Description

Technical Field

[0001] This application relates to the field of vehicle interiors, and more particularly to a child lock cover assembly and a vehicle. Background Technology

[0002] As a standard interior feature of passenger cars, rear coat racks typically lack dedicated storage space. For ease of use, car accessories such as tissue boxes are usually placed on the surface of the coat rack.

[0003] In related technologies, additional structures are installed on the surface of coat racks to fix in-vehicle accessories such as tissue boxes. However, these additional structures are mostly adhesive or integrated structures that need to be fixed to the coat rack, making them difficult to repair or replace after installation. Summary of the Invention

[0004] To address the aforementioned technical problems, this application provides a child lock cover assembly and a vehicle, which allows for easy disassembly, maintenance, and replacement of vehicle accessories such as tissue boxes that are fixed to the surface of a coat rack.

[0005] In a first aspect, this application provides a child lock cover assembly, including a main body, a bracket, and a snap-fit ​​structure; wherein, the bracket is connected to the main body, and a receiving cavity and a connecting channel are formed between the bracket and the main body, the receiving cavity is connected to the external environment through the connecting channel, the receiving cavity is used to accommodate a magnetic attractor, and the magnetic attractor enters and exits the receiving cavity through the connecting channel; the snap-fit ​​structure is connected to the bracket, and at least part of the snap-fit ​​structure extends between the bracket and the main body to restrict the displacement of the magnetic attractor from the receiving cavity to the connecting channel.

[0006] The child lock cover assembly provided in this application forms a cavity for accommodating a magnetic component in the space between the main body and the bracket. This cavity is connected to the outside via a connecting channel. The magnetic component enters the cavity through the connecting channel, enabling installation between the main body and the bracket. The portion of the snap-fit ​​structure extending between the bracket and the main body is located on the path of the magnetic component's displacement from the cavity to the connecting channel, thus confining the magnetic component inside the cavity after insertion and ensuring its reliability. Based on this, the magnetic component provides a foundation for magnetic fixation. Car accessories such as tissue boxes can be magnetically fixed to the surface of the coat rack with minimal modification to the vehicle structure, preserving the coat rack's aesthetics when not in use. When the magnetic component needs replacement, simply release the locking mechanism between the snap-fit ​​structure and the magnetic component to remove it from the cavity along the connecting channel; after a new magnetic component is inserted via the connecting channel, the snap-fit ​​structure returns to its locking state. Thus, through the cooperation of the main body, bracket and snap-fit ​​structure, the magnetic component can be repeatedly installed and removed inside the child lock cover assembly, thereby using magnetic force to fix car accessories such as tissue boxes, while facilitating the maintenance and replacement of the magnetic component.

[0007] In some implementations, the snap-fit ​​structure includes a connector and a limiting member. The first end of the connector is connected to the limiting member, and the second end of the connector is connected to the bracket. The limiting member is located between the bracket and the main body and can abut against the magnetic member. The connector can undergo elastic deformation relative to the bracket to move the limiting member away from the accommodating cavity.

[0008] In some implementations, the bracket has a release groove at the snap-fit ​​structure, which connects the accommodating cavity to the external environment, and the connector can deform to one side of the release groove.

[0009] In some implementations, the support has a through groove located on the side of the accommodating cavity away from the connecting channel, and the through groove connects the accommodating cavity with the external environment.

[0010] In some implementations, a protrusion is provided on the side of the bracket facing the main body, and the magnetic component is interference-fitted between the protrusion and the main body.

[0011] In some implementations, a guide component is provided between the bracket and the main body. The guide component extends from the connecting channel to the accommodating cavity and forms an installation space between the bracket and the main body. The installation space has a first width dimension L1 at the connecting channel and a second width dimension L2 at the accommodating cavity. The magnetic suction component has a third width dimension L3. The third width dimension L3 satisfies: L1>L3 and L2<L3.

[0012] In some implementations, there is a gap between the sidewalls of the support and the guide assembly to form a buffer space.

[0013] In some implementations, the main body, support frame, and snap-fit ​​structure are integrally molded.

[0014] In some implementations, the support has an observation port that connects the accommodating cavity to the external environment.

[0015] Secondly, embodiments of this application provide a vehicle including a coat rack and a child lock cover assembly as described in the first aspect, wherein the main body is disposed on the coat rack.

[0016] In the vehicle of this application embodiment, since the child lock cover assembly of the first aspect is included, the same beneficial effects can be achieved. That is, the installation of vehicle accessories such as tissue boxes on the surface of the coat rack is convenient and quick, and the structure used to fix vehicle accessories such as tissue boxes is convenient for maintenance and replacement, and is easy to assemble and disassemble.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone.

[0030] The following is a detailed description of this application.

[0031] This application provides a vehicle, which is a machine powered by fuel or electricity used to transport people or goods. The vehicle can be a sedan, SUV, sport utility vehicle (SUV), multi-purpose vehicle (MPV), truck, bus, public transport, etc. The vehicle can refer to a fuel-powered vehicle, an electric vehicle, or a hybrid vehicle.

[0032] Some family cars have coat racks in the rear, located inside the windshield behind the rear seats. Originally intended to cover luggage, protect privacy, and support the rear window sunshade, coat racks typically have a flat surface without any designed storage or restraint mechanisms. In practice, frequently used small items are often left lying around on them, the most common being tissue boxes.

[0033] In related technologies, additional structures are typically added to coat racks to secure tissue boxes. For example, magnetic or fixing structures are directly adhered to the surface of the coat rack, allowing the tissue box to be attracted or snapped into a preset position. While this solves the problem of unstable tissue box placement, it has significant limitations. First, once the magnetic or fixing structure is attached to the back of the coat rack, it is difficult to remove. When the components age, the magnetic force weakens, or it becomes damaged, repair or replacement is almost impossible. Forcibly removing it can easily damage the original paint and interior structure of the coat rack. Second, the added structure is exposed on the front of the coat rack, making concealed installation impossible and resulting in poor aesthetics.

[0034] Based on this, the child lock covers on the left and right sides of the coat rack are usually purely decorative and closed, with a relatively simple function, only serving to cover and protect the back structure of the coat rack. This means that the space potential of the area around the coat rack is not fully utilized.

[0035] Therefore, how to provide a convenient and easy-to-replace / maintain accessory fixing solution for coat racks without affecting the integrity of the original vehicle interior has become a direction that needs to be improved in vehicle interior design.

[0036] This application provides a child lock cover assembly M1, referring to... Figure 1 , Figure 2 and Figure 2 The device includes a main body 1, a support 2, and a snap-fit ​​structure 3. The support 2 is connected to the main body 1, and a cavity 4 and a connecting channel 5 are formed between the support 2 and the main body 1. The cavity 4 is connected to the external environment through the connecting channel 5. The cavity 4 is used to accommodate a magnetic component 6, and the magnetic component 6 enters and exits the cavity 4 through the connecting channel 5. The snap-fit ​​structure 3 is connected to the support 2, and at least part of the snap-fit ​​structure 3 extends between the support 2 and the main body 1 to restrict the displacement of the magnetic component 6 from the cavity 4 to the connecting channel 5.

[0037] The child lock cover assembly M1 provided in this application has a receiving cavity 4 formed in the space between the main body 1 and the bracket 2 for placing the magnetic component 6. The receiving cavity 4 is connected to the outside through a connecting channel 5. The magnetic component 6 enters the receiving cavity 4 through the connecting channel 5 to achieve installation between the main body 1 and the bracket 2. The portion of the snap-fit ​​structure 3 extending between the bracket 2 and the main body 1 is located on the path of the magnetic component 6 as it moves from the receiving cavity 4 to the connecting channel 5, thereby confining the magnetic component 6 inside the receiving cavity 4 after it is inserted, ensuring the reliability of the magnetic component 6 after installation.

[0038] Based on this, the magnetic attachment 6 provides a foundation for magnetic fixation. Car accessories such as tissue boxes can be magnetically fixed to the surface of the coat rack M2 with minimal alteration to the vehicle's structure, preserving the aesthetic appeal of the coat rack M2 when not in use. When the magnetic attachment 6 needs replacement, simply release the limiting position between the locking structure 3 and the magnetic attachment 6, allowing the magnetic attachment 6 to exit through the accommodating cavity 4 along the connecting channel 5. After the new magnetic attachment 6 is inserted through the connecting channel 5, the locking structure 3 returns to its limiting position. Thus, through the cooperation of the main body 1, the bracket 2, and the locking structure 3, the magnetic attachment 6 can be repeatedly installed and removed from inside the child lock cover assembly M1, facilitating both the magnetic fixation of car accessories such as tissue boxes and the maintenance and replacement of the magnetic attachment 6.

[0039] Reference Figure 1 and Figure 2The cover plate of the original child lock of the coat rack M2 can be used as the main body 1 of the child lock cover plate assembly M1 in this application. The main body 1 is distributed on the back of the coat rack M2, so that the front of the coat rack M2 still retains its integrity.

[0040] Two main bodies 1 can be set on the coat rack M2. The two main bodies 1 are symmetrically set on the coat rack M2 to form two magnetic areas, so as to provide multiple fixing points for in-vehicle accessories such as tissue boxes. Passengers can adjust the fixing position of the tissue box according to their seating position.

[0041] The main body 1 has an inner surface facing the coat rack M2 and an outer surface facing away from the coat rack M2, and the bracket 2 is connected to the outer surface of the main body 1. (Refer to...) Figure 3 The bracket 2 is a box-shaped structure that is fastened to the outer surface of the main body 1. The middle region of the bracket 2 arches away from the main body 1 to form a gap between the bracket 2 and the main body 1. The accommodating cavity 4 and the connecting channel 5 are located in the gap.

[0042] The support 2 includes an integrally formed first segment 21 and a second segment 22. The first segment 21 forms a connecting channel 5 with the main body 1, and the second segment 22 forms an accommodating cavity 4 with the main body 1. (Refer to...) Figure 4 The first segment 21 has an opening at one end away from the second segment 22, which serves as a connection port between the channel 5 and the external environment, allowing the magnetic component 6 to enter and exit.

[0043] It should be noted that the edge of the second segment 22 is semi-closed or closed in the circumferential direction, so that after the magnetic attractor 6 enters the accommodating cavity 4, the inner wall of the second segment 22 (i.e. the wall surface of the accommodating cavity 4) forms a circumferential limit on the magnetic attractor 6.

[0044] The magnetic component 6 can be a cylindrical permanent magnet. The two ends of the magnetic component 6 along its own axis are the N pole and the S pole, respectively. In this embodiment, the S pole of the magnetic component 6 faces the coat rack M2, and the N pole faces away from the coat rack M2, so as to accurately attract and match with car accessories such as magnetic tissue boxes.

[0045] The portion of the snap-fit ​​structure 3 extending between the bracket 2 and the main body 1 can be located between the first segment 21 and the second segment 22, that is, between the accommodating cavity 4 and the connecting channel 5. The limiting method of this portion of the snap-fit ​​structure 3 for the magnetic suction member 6 can be that it abuts against the magnetic suction member 6. For example, in the embodiment of this application, the snap-fit ​​structure 3 abuts against the side of the magnetic suction member 6 facing the connecting channel 5 to create motion interference with the magnetic suction member 6 and prevent the magnetic suction member 6 from moving into the connecting channel 5.

[0046] The relative positions of the snap-fit ​​structure 3 and the magnetic suction component 6 can be adjusted. The snap-fit ​​structure 3 can be located on the side of the accommodating cavity 4 closer to the main body 1, or on the side of the accommodating cavity 4 closer to the bracket 2, or on the side wall of the bracket 2, as long as it can form a limiting contact with the magnetic suction component 6.

[0047] After the main body 1 is mounted on the surface of the coat rack M2, the magnetic force generated by the magnetic component 6 passes through the main body 1 and the coat rack M2, attracting the magnetic material on the tissue box, thereby fixing the tissue box to the surface of the coat rack M2. During vehicle operation, the magnetic force continues to act to keep the tissue box in a stable position.

[0048] It should be noted that the outer side of the main body 1 is usually also provided with an outer shell 7. The outer shell 7 surrounds the outer perimeter of the main body 1 and extends partially to the side of the main body 1 away from the coat rack M2, in order to protect the main body 1 and the support 2. The main body 1 and the outer shell 7 are connected by a snap-fit ​​mechanism, and the outer shell 7 is connected to the coat rack M2 by a snap-fit ​​mechanism.

[0049] Reference Figure 5 and Figure 6 The snap-fit ​​structure 3 includes a connector 31 and a limiting member 32. The first end of the connector 31 is connected to the limiting member 32, and the second end of the connector 31 is connected to the bracket 2. The limiting member 32 is located between the bracket 2 and the main body 1 and can abut against the magnetic member 6. The connector 31 can undergo elastic deformation relative to the bracket 2 to drive the limiting member 32 away from the accommodating cavity 4.

[0050] The first end of the connector 31 is connected to the limiting member 32, and the second end is connected to the bracket 2. In its natural state, the limiting member 32 remains on the displacement path of the magnetic chuck 6 towards the connecting channel 5. When the magnetic chuck 6 needs to be removed, the connector 31 undergoes elastic deformation, causing the limiting member 32 to move out of this displacement path. Thus, both the limiting and releasing functions of the limiting member 32 on the magnetic chuck 6 are achieved through the elastic deformation of the connector 31, allowing for repeated limiting and removal operations of the magnetic chuck 6, further improving the convenience of maintenance and replacement of the magnetic chuck 6.

[0051] The connector 31 and the limiting member 32 can be integrally formed, that is, the limiting member 32 is formed by bending the end of the connector 31 into the cavity 4. The limiting member 32 can be a sheet-like structure, or it can be bent to the end to contact the connector 31, forming a hollow closed structure to enhance its own strength.

[0052] After the magnetic suction member 6 is inserted into the receiving cavity 4, the limiting member 32 can abut against the side surface of the magnetic suction member 6 facing the connecting channel 5. It should be noted that the distance between the limiting member 32 and the end wall of the receiving cavity 4 away from the connecting channel 5 can be set to match the size of the magnetic suction member 6, so as to form a bidirectional limiting on the magnetic suction member 6 in the insertion direction and ensure the stability of the magnetic suction member 6.

[0053] The connector 31 can be a cantilever structure. The end of the connector 31 away from the limiting member 32 is a fixed end and fixed to the bracket 2, while the end with the limiting member 32 is a free end. When an external force is applied to the limiting member 32 or the connector 31, the connector 31 undergoes bending elastic deformation, and the free end of the connector 31 is displaced relative to the fixed end, thereby causing the limiting member 32 to move away from the accommodating cavity 4. When the external force is released, the connector 31 returns to its natural state under the action of elastic restoring force, and the limiting member 32 returns to the position extending into the displacement path.

[0054] In this embodiment, the connector 31 is a sheet structure, and the limiting member 32 is a tubular structure. To facilitate the smooth insertion of the magnetic 6, the limiting member 32 has a guide slope or chamfer structure on the side away from the connector 31 and facing the connecting channel 5, which is used to form an abutment with the magnetic 6 when it is inserted.

[0055] As the magnetic chuck 6 enters the accommodating cavity 4 via the connecting channel 5, its outer wall first contacts the guide slope or chamfer structure of the limiting member 32. As the magnetic chuck 6 continues to move into the accommodating cavity 4, it pushes the limiting member 32 and causes the connecting member 31 to undergo elastic deformation. The limiting member 32 moves away from the accommodating cavity 4, making way for the magnetic chuck 6. When the magnetic chuck 6 has completely entered the accommodating cavity 4, its pushing effect on the limiting member 32 disappears, and the connecting member 31 resets under the action of elastic restoring force. The limiting member 32 follows the connecting member 31 back to its natural position. At this time, the limiting member 32 abuts against the side surface of the magnetic chuck 6 facing the connecting channel 5, confining the magnetic chuck 6 inside the accommodating cavity 4.

[0056] When it is necessary to remove the magnetic chuck 6 from the accommodating cavity 4, an external force is applied to the limiting member 32 or the connecting member 31 in a direction away from the accommodating cavity 4. The connecting member 31 undergoes elastic deformation and drives the limiting member 32 away from the accommodating cavity 4. After the limiting member 32 disengages from the displacement path of the magnetic chuck 6 toward the connecting channel 5, the magnetic chuck 6 can then be moved out of the accommodating cavity 4 along the connecting channel 5. After the external force is released, the connecting member 31 returns to its natural state, and the limiting member 32 returns to its initial position.

[0057] Reference Figure 5 and Figure 6 The bracket 2 has a release groove 23 at the snap-fit ​​structure 3. The release groove 23 connects the accommodating cavity 4 with the external environment, and the connector 31 can deform to one side of the release groove 23.

[0058] The release groove 23 forms a space on the bracket 2 for the connector 31 to move into when it deforms, and the release groove 23 is connected to the external environment, providing an operating space for external tools or fingers to be inserted into the location of the connector 31.

[0059] The first segment 21 and the second segment 22 of the bracket 2 each have an end face opposite to the main body 1. A connector 31 is provided to connect with the second segment 22, and a release groove 23 is provided on the end face corresponding to the second segment 22. The release groove 23 penetrates the end face of the second segment 22 to form a connection between the accommodating cavity 4 and the external environment.

[0060] To facilitate the displacement of the connector 31 and the limiting member 32, the opening range of the release groove 23 on the projection surface of the bracket 2 facing the main body 1 should at least completely cover the outline range of the snap-fit ​​structure 3 to provide sufficient deformation space.

[0061] Meanwhile, the width of the release groove 23 is greater than the width of the connector 31, wherein the width direction is perpendicular to the deformation direction of the connector 31, so that at least one inner wall of the release groove 23 extends beyond the outer wall of the snap-fit ​​structure 3 to form a preset gap. Through the preset gap, external tools (such as screwdrivers, pry bars) or fingers can be inserted into the location of the connector 31 to apply an external force to the connector 31 away from the direction of the receiving cavity 4.

[0062] In this embodiment, the connector 31 can be connected to the side of the release groove 23 closer to the interior of the accommodating cavity 4, so that the limiting member 32 is closer to the displacement path of the magnetic suction member 6, and prevents the snap-fit ​​structure 3 from occupying the external environmental space of the bracket 2 in the free state. When subjected to force, the connector 31 can move away from the accommodating cavity 4, that is, enter the release groove 23 or pass through the release groove 23 to the external environment.

[0063] Reference Figure 7 The bracket 2 has a through groove 24, which is located on the side of the accommodating cavity 4 away from the connecting channel 5, and the through groove 24 connects the accommodating cavity 4 with the external environment.

[0064] The through groove 24 provides an independent force path for removing the magnetic 6. After the locking structure 3 is released, a tool or finger can be inserted into the cavity 4 through the through groove 24 and a pushing force can be applied to the magnetic 6 in the direction of the connecting channel 5. Under the action of this pushing force, the magnetic 6 moves outward along the connecting channel 5 and exits the cavity 4, so that the magnetic 6 can be removed from the connecting channel 5 without the need for clamping or prying, which further reduces the difficulty of disassembling the magnetic 6.

[0065] The bracket 2 has a side perpendicular to the end face, and the through groove 24 penetrates the side of the bracket 2 to connect the accommodating cavity 4 to the external environment. The extension direction of the through groove 24 is parallel or nearly parallel to the line connecting the connecting channel 5 and the accommodating cavity 4, that is, the through groove 24 is located at the other end of the accommodating cavity 4 opposite to the connecting channel 5.

[0066] It should be noted that the opening size of the through slot 24 should be larger than the head size of a conventional tool (such as a screwdriver or a pick) so that the tool can be inserted into the cavity 4 through the through slot 24. At the same time, the opening size of the through slot 24 should not be larger than the width of the magnetic component 6 to ensure that the side of the bracket 2 effectively limits the magnetic component 6 and prevents the magnetic component 6 from moving out of the through slot 24.

[0067] During the process of removing the magnetic chuck 6 from the accommodating cavity 4, an external force is first applied to the locking structure 3 to disengage the limiting member 32 of the locking structure 3 from its limiting position on the magnetic chuck 6. Subsequently, a tool is inserted into the accommodating cavity 4 through the through groove 24 to apply a pushing force to the magnetic chuck 6 in the direction of the connecting channel 5, thereby driving the magnetic chuck 6 to move along the accommodating cavity 4 towards the connecting channel 5, and finally remove it to the external environment.

[0068] In some other embodiments, the through slot 24 may also be provided at other locations on the bracket 2, such as other locations on the side or at the end face. As long as the through slot 24 can connect the accommodating cavity 4 with the external environment, and the tool can apply a pushing force toward the connecting channel 5 after being inserted through the through slot 24, the function of pushing the magnetic member 6 out of the connecting channel 5 can also be achieved.

[0069] The number of through slots 24 can also be set to multiple, located at different positions of the bracket 2, so as to apply a pushing force to the magnetic attractor 6 from different angles.

[0070] Reference Figure 4 and Figure 8 The bracket 2 has a protrusion 26 on the side facing the main body 1, and the magnetic component 6 is interference-fitted between the protrusion 26 and the main body 1.

[0071] The protrusion 26 forms a local contact area between the main body 1 and the magnetic component 6. At this local contact area, the magnetic component 6 is subjected to compression from both the protrusion 26 and the main body 1 along its height direction, thereby stably clamping the magnetic component 6. Compared to the large-area frictional engagement between the bracket 2 and the magnetic component 6, the protrusion 26 contacts the magnetic component 6 with a small area, providing stable positioning while reducing the contact area between the magnetic component 6 and the bracket 2. This reduces wear on the surfaces of the bracket 2 and the magnetic component 6 during repeated assembly and disassembly of the magnetic component 6.

[0072] The protrusion 26 can be formed by a local portion of the end face of the bracket 2 protruding towards one side of the main body 1, that is, the protrusion 26 and the bracket 2 are integrally injection molded. In other embodiments, the protrusion 26 can also be provided on the side of the main body 1 facing the bracket 2.

[0073] The protrusion 26 may not only be disposed within the accommodating cavity 4, but may also be disposed within the connecting channel 5 to provide a continuous limiting effect on the magnetic attractor 6. That is, the protrusion 26 extends from the connecting channel 5 into the accommodating cavity 4. In some embodiments, the extending direction of the protrusion 26 may be parallel or nearly parallel to the line connecting the connecting channel 5 and the accommodating cavity 4.

[0074] The number of protrusions 26 can be one or more. In this embodiment, two protrusions 26 are provided as an example. The two protrusions 26 are arranged in parallel and are symmetrical about the central axis of the bracket 2.

[0075] The protrusion height of the protrusion 26 is set such that after the magnetic chuck 6 is inserted into the accommodating cavity 4, the side surface of the magnetic chuck 6 facing the bracket 2 contacts the protrusion 26, while the side surface of the magnetic chuck 6 facing the main body 1 contacts the surface of the main body 1. That is, the thickness of the magnetic chuck 6 is greater than the distance between the top of the protrusion 26 and the surface of the main body 1, so that after the magnetic chuck 6 is inserted, the magnetic chuck 6 is subjected to a bidirectional compressive force jointly applied by the protrusion 26 and the surface of the main body 1 at the location of the protrusion 26, forming an interference fit.

[0076] The distance between the area of ​​the bracket 2 without the protrusion 26 and the surface of the main body 1 should be greater than the thickness of the magnetic component 6 to avoid contact with the magnetic component 6.

[0077] In different embodiments, the height of the protrusion 26 can be set differently. For example, the distance between the top of the protrusion 26 and the surface of the main body 1 is set differently at the accommodating cavity 4 and the connecting channel 5. The distance at the accommodating cavity 4 is smaller than the distance at the connecting channel 5, and the distance at the accommodating cavity 4 is not greater than the thickness of the magnetic member 6.

[0078] In this case, the top of the protrusion 26 can be an inclined plane, so that the spacing dimension decreases uniformly from the connecting channel 5 to the accommodating cavity 4; or it can be an arc surface, so that the spacing dimension changes uniformly or non-uniformly.

[0079] In different embodiments, the protrusion direction of the protrusion 26 relative to the inner wall surface of the bracket 2 may be perpendicular to the inner wall surface of the bracket 2 or inclined to the inner wall surface of the bracket 2.

[0080] The cross-sectional shape of the protrusion 26 can be trapezoidal, arc-shaped, rectangular, etc.

[0081] Reference Figure 9A guide component 8 is provided between the bracket 2 and the main body 1. The guide component 8 extends from the connecting channel 5 to the accommodating cavity 4, and the guide component 8 forms an installation space 41 between the bracket 2 and the main body 1. The installation space 41 has a first width dimension L1 at the connecting channel 5 and a second width dimension L2 at the accommodating cavity 4. The magnetic suction component 6 has a third width dimension L3 (not shown in the figure). The third width dimension L3 satisfies: L1>L3 and L2<L3.

[0082] When the magnetic suction component 6 enters through the connecting channel 5, the width of the installation space 41 at the connecting channel 5 is greater than the width of the magnetic suction component 6, allowing the magnetic suction component 6 to smoothly enter the installation space 41. As the magnetic suction component 6 advances towards the accommodating cavity 4, the width of the installation space 41 gradually narrows to less than the width of the magnetic suction component 6, causing the magnetic suction component 6 to form an interference fit with the guide component 8 at the accommodating cavity 4 and be clamped and fixed. Thus, the guide component 8 not only provides guidance for the insertion of the magnetic suction component 6, but also provides clamping and limiting functions after the magnetic suction component 6 is fully inserted, integrating the two functions of insertion and fixation into the same structure, achieving a compact design.

[0083] The guide assembly 8 includes two opposing guide members 81, which are located on either side of the central axis of the space between the bracket 2 and the main body 1. The two guide members 81 are connected to the two opposing side walls at the opening of the first section 21 of the bracket 2, and extend toward one side of the accommodating cavity 4, forming a guide path from the opening of the connecting channel 5 to the accommodating cavity 4.

[0084] Two guide members 81 together enclose the mounting space 41 between the bracket 2 and the main body 1. Specifically, there is an acute or obtuse angle between the extension direction of the guide member 81 and the moving direction of the magnetic suction member 6 entering the accommodating cavity 4 through the connecting channel 5 (the direction of the line connecting the connecting channel 5 and the accommodating cavity 4), so that the distance between the two guide members 81, that is, the width dimension of the mounting space 41, gradually decreases towards the side of the accommodating cavity 4.

[0085] In this embodiment, the two guide members 81 are symmetrically distributed about the central axis of the bracket 2, so that the displacement path of the magnetic suction member 6 is located on the central axis of the gap area formed between the bracket 2 and the main body 1.

[0086] In some embodiments, the height of the guide member 81 is consistent with the distance between the bracket 2 and the main body 1, that is, along the direction perpendicular to the main body 1, the two ends of the guide member 81 abut against the inner wall surface of the bracket 2 and the surface of the main body 1 facing the bracket 2 in the area where the protrusion 26 is not provided. The guide member 81 may be fixedly connected to the bracket 2 or fixedly connected to the main body 1.

[0087] The guide 81 can be configured as a sheet structure, and the guide 81 is arranged perpendicular to the surfaces of the main body 1 and the support 2. Alternatively, the guide 81 can be inclined to the surfaces of the main body 1 and the support 2, but can fit against the side wall of the magnetic attractor 6 to provide a stable limiting effect for the magnetic attractor 6.

[0088] The mounting space 41 has a first width dimension L1 at the connecting channel 5, which refers to the distance between the two guide members 81 at the opening of the connecting channel 5. The mounting space 41 has a second width dimension L2 at the accommodating cavity 4, which refers to the distance between the two guide members 81 at the accommodating cavity 4. The magnetic member 6 has a third width dimension L3, which refers to the dimension in the direction corresponding to the width direction of the mounting space 41. In this embodiment, the third width dimension L3 refers to the diameter of the magnetic member 6.

[0089] The portion of the guide member 81 within the accommodating cavity 4 can be parallel to the central axis of the accommodating cavity 4, meaning that the second width dimension L2 is equal at any position within the accommodating cavity 4, in order to provide stable clamping for the magnetic member 6.

[0090] The first width dimension L1 is greater than the third width dimension L3, so that when the magnetic suction member 6 enters the connecting channel 5, there is a gap between the two side edges of the magnetic suction member 6 and the two side inner walls of the mounting space 41, which facilitates the unobstructed entry of the magnetic suction member 6 into the mounting space 41, and at the same time, it also serves as a guide to prevent bumps. The second width dimension L2 is smaller than the third width dimension L3, so that when the magnetic suction member 6 reaches the position of the accommodating cavity 4, there is a pressing interference between the two side edges of the magnetic suction member 6 and the two guide members 81 along the width direction, so as to achieve an interference fit.

[0091] It should be noted that the guide member 81 can undergo elastic deformation relative to the bracket 2 and the main body 1, so that when the magnetic member 6 reaches the accommodating cavity 4, the two side walls of the magnetic member 6 form an interference fit with the two guide members 81, the guide member 81 undergoes elastic deformation and generates an elastic restoring force towards the magnetic member 6, clamping the magnetic member 6 between the two guide members 81.

[0092] Reference Figure 9 There is a gap between the side wall of the bracket 2 and the guide assembly 8 to form a buffer space 42.

[0093] During or after the main body 1 is assembled with the coat rack M2, the main body 1 will be subjected to external compressive force (such as assembly clamping force or vibration and impact force during vehicle operation). By separating the side wall of the bracket 2 from the guide component 8, the guide component 8 can elastically deform to one side of the buffer space 42 when compressed, thereby controlling the compressive force transmitted to the magnetic suction component 6 within the range that the magnetic suction component 6 can withstand. That is, the buffer space 42 can absorb and disperse the compressive force borne by the guide component 8, avoid the compressive force being directly transmitted to the magnetic suction component 6, and prevent the magnetic suction component 6 from breaking due to excessive compression.

[0094] The sidewall of bracket 2 refers to the side portion of bracket 2 that is perpendicular to the end face and connected to the main body 1. The sidewall of bracket 2 encloses and forms the side of the cavity 4. The guide component 8 is disposed on the inner side of the sidewall of bracket 2, and a gap is provided between the sidewall of bracket 2 and the corresponding guide component 81. The size of the gap is greater than zero, so that the guide component 81 and the corresponding sidewall of bracket 2 are physically separated. This gap forms a buffer space 42 between the wall surface of bracket 2 and the surface of guide component 8 facing the sidewall of bracket 2.

[0095] In some embodiments, the buffer space 42 can be a solid structure, while in other embodiments, the buffer space 42 can be a cavity structure.

[0096] The installation space 41 and the buffer space 42 together form the accommodating cavity 4. The guide 81 separates the installation space 41 and the buffer space 42, so that the magnetic suction component 6 exists only in the installation space 41.

[0097] To accommodate the cylindrical structure of the magnetic chuck 6, the second section 22 of the bracket 2 is a circular box-shaped structure, meaning the accommodating cavity 4 is a circular cavity with a diameter larger than that of the magnetic chuck 6. Correspondingly, the width of the buffer space 42 will adapt to the shape change of the magnetic chuck 6, thereby forming a near-annular cavity structure on the outer periphery of the magnetic chuck 6 that fits the peripheral wall of the magnetic chuck 6.

[0098] It should be noted that, since the bracket 2 needs to have a through groove 24 on the side of the accommodating cavity 4 away from the connecting channel 5, and the side of the bracket 2 corresponding to the through groove 24 forms a radial abutment against the magnetic member 6, the end of the guide member 81 away from the connecting channel 5 does not exceed the through groove 24. Therefore, the buffer space 42 forms a crescent shape that is wide in the middle and narrow at both ends. At both ends of the diameter line of the magnetic member perpendicular to the central axis of the bracket 2, the buffer space 42 has the largest width dimension to provide the required maximum displacement when the guide member 81 undergoes elastic deformation.

[0099] The main body 1, the bracket 2, and the snap-fit ​​structure 3 are integrally molded.

[0100] The main body 1, the bracket 2, and the snap-fit ​​structure 3 are formed into an integral component through a one-piece molding process. The three components can form a spatial structure of accommodating cavity 4 and connecting channel 5 without additional assembly processes. This eliminates the assembly gaps and connection tolerances between the main body 1 and the bracket 2, and between the bracket 2 and the snap-fit ​​structure 3. This ensures that when the magnetic suction part 6 is limited in the accommodating cavity 4, the positional accuracy and limiting reliability of the snap-fit ​​structure 3 are not affected by assembly errors. At the same time, it simplifies the manufacturing and assembly process of the child lock cover assembly M1, and ensures the limiting accuracy of the snap-fit ​​structure 3 for the magnetic suction part 6 and the long-term stability of its use.

[0101] The main body 1, the bracket 2, and the snap-fit ​​structure 3 can be made of the same plastic material and integrally formed in a single mold through injection molding. The bracket 2 and the snap-fit ​​structure 3 are integrally formed on the main body 1 and can open and close synchronously with the main body 1. During the opening and closing process, the magnetic part 6 remains inside the accommodating cavity 4 and does not affect the original protective and shielding functions of the main body 1.

[0102] In one alternative embodiment, the bracket 2 is made of a PC (polycarbonate) + ABS (acrylonitrile butadiene styrene) composite material. The PC+ABS composite material combines the high strength of polycarbonate with the good molding and processing properties of acrylonitrile butadiene styrene copolymer, and also has aging resistance, making it suitable for the use environment of automotive interiors. Furthermore, the bracket 2 is integrally formed with the main body 1 and the snap-fit ​​structure 3 through injection molding, making the integrally molded snap-fit ​​structure 3 less prone to fatigue fracture during repeated elastic deformation, thus ensuring the long-term reliability of the snap-fit ​​structure 3 in positioning the magnetic component 6.

[0103] Reference Figure 3 The bracket 2 has an observation port 25, which connects the accommodating cavity 4 with the external environment.

[0104] By forming a through channel on the bracket 2 through the observation port 25, the position of the magnetic suction component 6 inside the accommodating cavity 4 can be directly observed through the observation port 25 during the process of the magnetic suction component 6 being placed into the accommodating cavity 4 via the connecting channel 5. This avoids the risk of limiting failure or loosening of the magnetic suction component 6 caused by the locking structure 3 being prematurely limited due to the magnetic suction component 6 not being fully placed.

[0105] The observation port 25 is opened on the end face of the second section 22 of the bracket 2 and penetrates the end face of the bracket 2 in a direction perpendicular to the main body 1.

[0106] The observation port 25 can be circular, elliptical, arc-shaped, rectangular, or elongated, and its opening area is smaller than the surface area of ​​the magnetic component 6 facing the bracket 2, so as to prevent the magnetic component 6 from falling out of the observation port 25.

[0107] The observation port 25 can be set to one or more. When multiple observation ports 25 are set, the multiple observation ports 25 are distributed in different areas of the corresponding accommodating cavity 4 of the bracket 2, and are arranged at intervals along the extension direction or circumferential direction of the accommodating cavity 4, so that the operator can observe the state of the magnetic suction component 6 in different parts of the accommodating cavity 4 from different positions.

[0108] It should be noted that the position of the observation port 25 can be set to correspond to the position of the guide 81, so that the edge of the magnetic suction component 6 can be directly observed, thereby improving the accuracy of judging the installation position of the magnetic suction component 6.

[0109] In this embodiment, the release groove 23 is disposed on the central axis of the bracket 2, and multiple observation ports 25 are symmetrically distributed on both sides of the release groove 23, but the observation ports 25 can be offset from the release groove 23 in the width direction.

[0110] In some embodiments, the observation port 25 may also be provided on the side of the bracket 2 to provide a field of view at different angles.

[0111] This application also provides a vehicle, as shown in the embodiments. Figure 1 and Figure 2 It includes a coat rack M2 and a child lock cover assembly M1 as described in the above embodiment, wherein the main body 1 is disposed on the coat rack M2.

[0112] In the vehicle of this application, since the child lock cover assembly M1 of the above embodiment is included, the same beneficial effects can be achieved. That is, the installation of vehicle accessories such as tissue boxes on the surface of the coat rack M2 is convenient and quick, and the structure used to fix vehicle accessories such as tissue boxes is convenient for maintenance and replacement, and is easy to assemble and disassemble.

[0113] The connection between the main body 1 and the coat rack M2 can retain the original connection structure between the child lock cover plate and the coat rack M2. That is, the main body 1 can be fixed to the coat rack M2 by snap-fit, so as to reduce the changes to the original vehicle structure.

[0114] In one alternative embodiment, after the main body 1 and the bracket 2 are integrally molded by injection molding, the magnetic suction component 6 is inserted into the receiving cavity 4 through the connecting channel 5 from the opening. After the magnetic suction component 6 is fully inserted into the receiving cavity 4, the locking structure 3 limits the magnetic suction component 6. Subsequently, the child lock cover assembly M1 is integrally snapped and installed into the preset installation position of the coat rack M2.

[0115] The child lock cover assembly M1 is fixedly connected to the coat rack M2 by a snap-fit ​​method, and the assembly can be completed without drilling or pasting. The assembly method is the same as the original child lock cover installation method.

[0116] In other embodiments, the child lock cover assembly M1 can also be located in other locations in the vehicle interior, and is not limited to the coat rack M2.

[0117] The above description is merely a specific embodiment of this application, enabling those skilled in the art to understand or implement this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments described herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
