Description

Technical Field

[0001] This application relates to the field of automotive parts technology, and in particular to bracket assemblies and automobiles. Background Technology

[0002] A safety hammer is an escape tool that can be used to strike vulnerable parts of a car, such as car windows, to help users escape in emergency situations.

[0003] In related technologies, safety hammers are generally placed inside the vehicle, such as in the trunk, which makes them inconvenient for users to access. Utility Model Content

[0004] In view of this, this application provides a bracket assembly and a vehicle to improve the ease of access to the safety hammer.

[0005] Specifically, the following technical solutions are included:

[0006] A first aspect of this application provides a support assembly, the support assembly including an assembly and a support member, wherein...

[0007] The mounting surface of the assembly is used to mount a safety hammer.

[0008] One side of the support member is connected to the side of the assembly that is away from the assembly surface, and the support member is capable of contracting axially and undergoing elastic deformation.

[0009] In some possible implementations, the support member includes a first connecting portion, a second connecting portion, and an elastic portion. A telescopic cavity is formed between one end of the first connecting portion and one end of the second connecting portion. The elastic portion connects the first connecting portion and the second connecting portion within the telescopic cavity. The first connecting portion is connected to the side of the assembly facing away from the mounting surface. The second connecting portion is capable of approaching and moving away from the first connecting portion along the telescopic direction of the elastic portion.

[0010] With the above arrangement, the first connecting part and the second connecting part can be used to abut at different positions on the vehicle. The force generated by the abutment can cause the second connecting part to move closer to the first connecting part, and cause the telescopic cavity to contract and compress the elastic part, causing the elastic part to undergo elastic deformation. The elastic part that has undergone elastic deformation can generate elastic force, and the elastic force, as a reaction force, can keep the support member in a state of force balance and increase the pressure at the abutment position, thereby achieving relative fixation of the position of the support member.

[0011] In some possible implementations, the first connecting portion includes a first telescopic hole, the second connecting portion includes a second telescopic hole, the opening of the first telescopic hole extends into the second telescopic hole from the opening of the second telescopic hole, and together with the second telescopic hole, form the telescopic cavity.

[0012] With the above arrangement, the telescopic cavity formed by the first telescopic hole and the second telescopic hole helps to protect and shield the elastic part, reducing interference to the elastic part. Specifically, the opening of the first telescopic hole extends into the opening of the second telescopic hole, and the walls of the first and second telescopic holes overlap. As the degree of contraction of the telescopic cavity increases, the area of ​​the overlapping part also increases, thus achieving the contraction of the telescopic cavity.

[0013] In some possible implementations, the first connecting portion includes a rib located within the first telescopic hole and extending axially along the first telescopic hole, with one end of the elastic portion abutting against one end of the rib.

[0014] With the above arrangement, the ribs help to improve the structural strength of the first expansion hole. By abutting against one end of the elastic part, the ribs help to reduce the direct action of the elastic part on the bottom of the first expansion hole, thereby preventing the elastic force generated by the elastic part from being too large and damaging the first connecting part.

[0015] In some possible implementations, the first connecting portion includes a first guide portion located on the outer wall surface of the first telescopic hole, and the second connecting portion includes a second guide portion located on the inner wall surface of the second telescopic hole. Both the first guide portion and the second guide portion extend along the telescopic direction of the elastic portion, and the first guide portion and the second guide portion are connected in cooperation.

[0016] Through the above arrangement, the cooperation between the first guide part and the second guide part is conducive to the second connecting part moving closer to and further away from the first connecting part along the expansion and contraction direction of the elastic part. This is conducive to the elastic part being subjected to a force along its contraction direction and undergoing elastic deformation.

[0017] In some possible implementations, the first connecting portion includes a first limiting body, the second connecting portion includes a second limiting body, the first limiting body and the second limiting body are connected in cooperation, the orthographic projection of the first limiting body on the projection plane and the orthographic projection of the second limiting body on the projection plane at least partially coincide, and the projection plane is a plane perpendicular to the extension and retraction direction of the elastic portion.

[0018] Through the above arrangement, the cooperation between the first and second limiting bodies helps to reduce the possibility of the second connecting part detaching from the first connecting part. Specifically, there is a space between the first and second limiting bodies that allows movement along the extension and contraction direction of the elastic part. The orthographic projections of the first and second limiting bodies on the projection plane at least partially overlap. When the second connecting part moves to the extreme position of the aforementioned space, it will be interfered with by the first connecting part. This interference will restrict the second connecting part from continuing to move, thereby helping to prevent the first and second connecting parts from detaching.

[0019] In some possible implementations, the support includes a force-bearing portion for receiving force to cause the support to contract axially.

[0020] With the above arrangement, since the two ends of the support need to be adjusted to abut against the car so that the contraction direction of the elastic element is collinear with the direction of the pressure generated by the abutment, the stability of the support is improved. Therefore, the assembler can compress the support in advance through the force-bearing part. After adjusting the position of the support, the force-bearing part can be released so that the two ends of the support abut against different positions.

[0021] In some possible implementations, the assembly includes a through hole extending from the surface of the support to the mounting surface, wherein the force-bearing portion is located within the through hole in the orthographic projection of the support.

[0022] With the above arrangement, the holes facilitate the application of pressure to the stressed parts by the assembler through the holes during the assembly of the support components. This allows the support to shrink in advance, which is beneficial for its two ends to abut against different positions.

[0023] In some possible implementations, the assembly includes a support plate and an assembly slot, the opening of which faces away from the support plate, and the assembly slot is used to engage with the safety hammer.

[0024] With the above arrangement, the opening of the assembly slot can allow the safety hammer to pass through, which is beneficial for the safety hammer to engage with the assembly slot to complete the assembly.

[0025] In some possible implementations, the assembly groove includes a first segment and a second segment, the first segment having a smaller cross-sectional area than the second segment, and the first segment being closer to the opening of the assembly groove than the second segment.

[0026] With the above arrangement, the second section can accommodate the safety hammer, and the first section can interfere with the safety hammer in the second section. This interference helps the safety hammer to engage with the assembly slot, so that it is confined within the assembly slot and assembled.

[0027] In some possible implementations, the assembly slot includes a first slot and a second slot, the first slot extending along the width direction of the support plate and the second slot extending along the length direction of the support plate, the first slot having a through opening facing one end of the second slot and communicating with the second slot.

[0028] With the above arrangement, the shape of the assembly slot is close enough to match the shape of the safety hammer, which is conducive to the first slot engaging the hammer head part of the safety hammer, and the second slot engaging the hammer handle part of the safety hammer, thereby realizing the assembly of the safety hammer.

[0029] A second aspect of this application provides an automobile that includes a bracket assembly as described in the above technical solutions.

[0030] In some possible implementations, the vehicle includes a first support and a second support, the support having a first end and a second end along the axial direction, the first end abutting against the first support and the second end abutting against the second support.

[0031] With the above arrangement, the first support part and the second support part can abut against the two ends of the support member, so as to achieve relative fixation of the position of the support member, which is beneficial to improving the stability of the position of the safety hammer assembled in the assembly.

[0032] The beneficial effects of the technical solution provided in this application include at least the following: the axial ends of the support member can abut against different positions on the vehicle, thereby contracting and undergoing elastic deformation. This allows the support member to generate elastic force, which increases the pressure at the abutment position, thus increasing the frictional force required for the support member to slide. This maintains the relative fixation of the position and provides sufficient support force to the assembly, ensuring the relatively fixed position of the safety hammer located on the assembly surface. The relatively fixed position of the safety hammer facilitates easy access for the user after installation, improving retrieval convenience. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] In the embodiments of this application, directional terms such as "upper," "lower," and "side" are generally used in the following ways: Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0048] Unless otherwise defined, all technical terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art.

[0049] To make the technical solutions and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0050] The first aspect of this application provides a support assembly, such as Figure 1 As shown, the bracket assembly includes an assembly 1 and a support 2, wherein,

[0051] The mounting surface of assembly 1 is used to assemble safety hammer 3.

[0052] One side of the support member 2 is connected to the side of the assembly 1 that is away from the assembly surface. The support member 2 can shrink axially and undergo elastic deformation.

[0053] With the above arrangement, the axial ends of the support member 2 can abut against different positions on the vehicle, thereby contracting and undergoing elastic deformation. This generates an elastic force in the support member 2, which increases the pressure at the abutment position and consequently increases the frictional force required for the support member 2 to slide. This maintains a relatively fixed position and provides sufficient support for the assembly 1, ensuring the relatively fixed position of the safety hammer 3 located on the assembly surface. The relatively fixed position of the safety hammer 3 facilitates easy access for the user after installation, improving retrieval convenience.

[0054] In this embodiment, the assembly 1 and the support 2 can be manufactured by an integral molding process, so that one side of the support 2 is connected to the side of the assembly 1 that is away from the assembly surface.

[0055] In this embodiment, the assembly 1 can be connected to the safety hammer 3 by means of snap-fit, bolt connection or other methods to complete the assembly.

[0056] In this embodiment, the two ends of the support member 2 in the axial direction can be fixed by abutting against components that are arranged opposite to the car and spaced apart from each other.

[0057] In this embodiment, when the support member 2 undergoes elastic deformation, it tends to return to its original shape. When this tendency acts on the abutment position, it will generate corresponding pressure, thereby increasing the frictional force required for the support member 2 to slide.

[0058] In some embodiments of this application, such as Figure 1 and Figure 2As shown, the support member 2 includes a first connecting part 21, a second connecting part 22, and an elastic part 23. A telescopic cavity 200 is formed between one end of the first connecting part 21 and one end of the second connecting part 22. The elastic part 23 connects the first connecting part 21 and the second connecting part 22 within the telescopic cavity 200. The first connecting part 21 is connected to the side of the assembly 1 that is away from the assembly surface. The second connecting part 22 can move closer to and away from the first connecting part 21 along the telescopic direction of the elastic part 23.

[0059] With the above arrangement, the first connecting part 21 and the second connecting part 22 can be used to abut at different positions on the vehicle. The force generated by the abutment can cause the second connecting part 22 to move closer to the first connecting part, and cause the telescopic cavity 200 to contract and compress the elastic part 23, causing the elastic part 23 to undergo elastic deformation. The elastic part 23, which undergoes elastic deformation, can generate elastic force. The elastic force, as a reaction force, can keep the support member 2 in a state of force balance and increase the pressure at the abutment position, thereby achieving relative fixation of the position of the support member 2.

[0060] In the embodiments of this application, the elastic part 23 can be a spring or other elastic component that can undergo elastic deformation.

[0061] In this embodiment of the application, the volume of the telescopic cavity 200 can be reduced due to compression, thereby causing the wall of the telescopic cavity 200 to abut against the elastic part 23, causing the elastic part 23 to undergo elastic deformation.

[0062] In some embodiments of this application, such as Figure 2 As shown, the first connecting part 21 includes a first telescopic hole 201, and the second connecting part 22 includes a second telescopic hole 202. The opening of the first telescopic hole 201 extends into the second telescopic hole 202 from the opening of the second telescopic hole 202, and together with the second telescopic hole 202, they form a telescopic cavity 200.

[0063] With the above arrangement, the telescopic cavity 200 formed by the first telescopic hole 201 and the second telescopic hole 202 helps to protect and shield the elastic part 23, reducing interference to the elastic part 23. Specifically, the opening of the first telescopic hole 201 extends into the opening of the second telescopic hole 202, and the walls of the first telescopic hole 201 and the second telescopic hole 202 overlap. As the degree of contraction of the telescopic cavity 200 increases, the area of ​​the overlapping portion also increases, thus achieving the contraction of the telescopic cavity 200.

[0064] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the first connecting part 21 includes a rib 211, which is located inside the first telescopic hole 201 and extends along the axial direction of the first telescopic hole 201. One end of the elastic part 23 abuts against one end of the rib 211.

[0065] With the above arrangement, the rib 211 helps to improve the structural strength of the first expansion hole 201. By abutting against one end of the elastic part 23, the rib 211 helps to reduce the direct action of the elastic part 23 on the bottom of the first expansion hole 201, thereby preventing the elastic force generated by the elastic part 23 from being too large and damaging the first connecting part 21.

[0066] In this embodiment of the application, there can be multiple ribs 211, and the multiple ribs 211 are arranged at intervals along the circumference of the first expansion hole 201.

[0067] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the first connecting part 21 includes a first guide part 212, which is located on the outer wall surface of the first telescopic hole 201. The second connecting part 22 includes a second guide part 221, which is located on the inner wall surface of the second telescopic hole 202. Both the first guide part 212 and the second guide part 221 extend along the telescopic direction of the elastic part 23, and the first guide part 212 and the second guide part 221 are connected in cooperation.

[0068] Through the above arrangement, the cooperation between the first guide portion 212 and the second guide portion 221 is beneficial for the second connecting portion 22 to move closer to and further away from the first connecting portion 21 along the extension and contraction direction of the elastic portion 23. This is beneficial for the elastic portion 23 to be subjected to a force along its contraction direction and undergo elastic deformation.

[0069] In this embodiment, the first guide portion 212 can be a protrusion, and the second guide portion 221 can be a groove. The first guide portion 212 extends into the second guide portion 221 and forms a mating connection with the second guide portion 221.

[0070] In this embodiment, the first guide portion 212 can be a groove, and the second guide portion 221 can be a protrusion. The second guide portion 221 extends into the first guide portion 212 and forms a mating connection with the second guide portion 221.

[0071] In this embodiment, there can be multiple first guide portions 212, which are arranged at circumferential intervals along the first telescopic hole 201. The number of second guide portions 221 can correspond to the number of first guide portions 212.

[0072] In some embodiments of this application, such as Figure 3 and Figure 4As shown, the first connecting part 21 includes a first limiting body 213, and the second connecting part 22 includes a second limiting body 222. The first limiting body 213 and the second limiting body 222 are connected in cooperation. The orthographic projection of the first limiting body 213 on the projection plane and the orthographic projection of the second limiting body 222 on the projection plane at least partially overlap. The projection plane is a plane perpendicular to the extension and retraction direction of the elastic part 23.

[0073] Through the above arrangement, the cooperation between the first limiting body 213 and the second limiting body 222 helps to reduce the possibility of the second connecting part 22 disengaging from the first connecting part 21. Specifically, there is a space between the first limiting body 213 and the second limiting body 222 that can move along the extension and retraction direction of the elastic part 23. The orthographic projection of the first limiting body 213 on the projection plane and the orthographic projection of the second limiting body 222 on the projection plane at least partially overlap. When the second connecting part 22 moves to the extreme position of the above space, it will be interfered with by the first connecting part 21. This interference will limit the continued movement of the second connecting part 22, thereby helping to prevent the first connecting part 21 and the second connecting part 22 from disengaging.

[0074] Meanwhile, the limiting effect of the first limiting body 213 also helps the support member 2 to be in a contracted state in its natural state, with the elastic part 23 in such a state. In this state, when the first connecting part 21 and the second connecting part 22 come into contact with different positions of the car, the elastic part 23 generates elastic force, thereby improving the stability of the bracket assembly.

[0075] In this embodiment, the first limiting body 213 can be a protrusion, and the second limiting body 222 can be a groove. The first limiting body 213 extends into the second limiting body 222 and forms a mating connection with the second limiting body 222.

[0076] In this embodiment, the first limiting body 213 can be a groove, and the second limiting body 222 can be a protrusion. The second limiting body 222 extends into the first limiting body 213 and forms a mating connection with the second limiting body 222.

[0077] In this embodiment, there can be multiple first limiting bodies 213, which are arranged at circumferential intervals along the first telescopic hole 201. The number of second limiting bodies 222 can correspond to the number of first limiting bodies 213.

[0078] In some embodiments of this application, such as Figure 2 and Figure 5 As shown, the support member 2 includes a force-receiving part 24, which is used to receive force to cause the support member 2 to contract axially.

[0079] With the above arrangement, since the two ends of the support member 2 need to be adjusted to abut against the car so that the contraction direction of the elastic member is collinear with the pressure direction generated by the abutment, the stability of the support member 2 is improved. Therefore, the assembler can compress the support member 2 in advance through the force-bearing part 24. After adjusting the position of the support member 2, the force-bearing part 24 can be released so that the two ends of the support member 2 abut against different positions.

[0080] In some embodiments of this application, such as Figure 2 and Figure 5 As shown, the assembly 1 includes a through hole 102, which extends from the surface of the support member 2 to the assembly surface. The force-bearing part 24 is located within the through hole 102 in the orthographic projection of the support member 2.

[0081] With the above arrangement, the through hole 102 facilitates the assembly personnel to apply pressure to the force-bearing part 24 through the through hole during the assembly of the bracket assembly. This allows the support member 2 to shrink in advance, which is beneficial for its two ends to abut against different positions.

[0082] In some embodiments of this application, such as Figure 5 As shown, the assembly 1 includes a support plate 11 and an assembly groove 101. The opening of the assembly groove 101 faces away from the support plate 11, and the assembly groove 101 is used to engage with the safety hammer 3.

[0083] With the above arrangement, the opening of the assembly slot 101 can allow the safety hammer 3 to pass through, which is conducive to the safety hammer 3 engaging with the assembly slot 101 in the assembly slot 101 to complete the assembly.

[0084] In some embodiments of this application, such as Figure 2 As shown, the assembly groove 101 includes a first section 1011 and a second section 1012. The cross-sectional area of ​​the first section 1011 is smaller than that of the second section 1012. The first section 1011 is closer to the opening of the assembly groove 101 than the second section 1012.

[0085] With the above arrangement, the second section 1012 can accommodate the safety hammer 3, and the first section 1011 can interfere with the safety hammer 3 in the second section 1012. This interference is conducive to the safety hammer 3 being snapped into the assembly groove 101 so that it can be confined within the assembly groove 101 and thus be assembled.

[0086] In some embodiments of this application, such as Figure 5 As shown, the assembly slot 101 includes a first slot 1013 and a second slot 1014. The first slot 1013 extends along the width direction of the support plate 11, and the second slot 1014 extends along the length direction of the support plate 11. The first slot 1013 has a through opening 10131, one end of which faces the second slot 1014 and communicates with the second slot 1014.

[0087] The safety hammer 3 is generally T-shaped. With the above arrangement, the shape of the assembly groove 101 is close enough to match the shape of the safety hammer 3, which is conducive to the first slot 1013 engaging the hammer head part of the safety hammer 3, and the second slot 1014 engaging the hammer handle part of the safety hammer 3, thereby realizing the assembly of the safety hammer 3.

[0088] A second aspect of this application provides an automobile that includes a bracket assembly as described above.

[0089] With the above arrangement, the automobile of this application has the same technical effects as the above embodiments, which will not be repeated here.

[0090] In the embodiments of this application, the automobile can be an automobile powered by an engine, an automobile powered by an electric motor, or an automobile powered by both an engine and an electric motor.

[0091] In some embodiments of this application, such as Figure 6 As shown, the car includes a first support part 41 and a second support part 42. The support member 2 has a first end and a second end along the axial direction. The first end abuts against the first support part 41 and the second end abuts against the second support part 42.

[0092] With the above arrangement, the first support part 41 and the second support part 42 can abut against the two ends of the support member 2, thereby achieving relative fixation of the position of the support member 2, which is beneficial to improving the stability of the position of the safety hammer 3 assembled in the assembly 1.

[0093] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.
