Description

TECHNICAL FIELD

[0001] The present application belongs to the field of automobile parts, and particularly relates to a joint device and a vehicle body. BACKGROUND

[0002] In some vehicles, such as fuel vehicles, electric vehicles or hybrid vehicles, a longitudinal beam needs to be connected with an energy absorption box through a joint device. Based on the safety consideration of the vehicle, the longitudinal beam, the energy absorption box and the joint device need to meet the requirements of the vehicle safety under the conditions of full-width frontal collision, double-vehicle collision and front collision center column. However, in the lateral collision of the longitudinal beam, the longitudinal beam is difficult to play a role. Therefore, using the existing joint device will result in insufficient overall strength of the related part of the vehicle body longitudinal beam, and cannot provide good side push support function. SUMMARY

[0003] The present application provides a joint device and a vehicle body, which can solve the problem of insufficient overall strength of the related part of the vehicle body longitudinal beam and the inability to provide good side push support function.

[0004] To solve the above technical problems, one technical solution adopted by the present application is to provide a joint device, which comprises: a frame body comprising a plurality of side walls connected in sequence, and a frame body internal space formed inside the plurality of side walls; at least one side wall is configured to connect external components; at least one reinforcing member is arranged in the frame body internal space, and the reinforcing member is connected with the side wall to form a plurality of accommodation spaces in the frame body internal space, and at least one of the accommodation spaces is provided with a reinforcing structure.

[0005] In the above manner, the frame body can realize the connection between a plurality of external components, and the reinforcing structure can enhance the structural strength of the frame body, and better conduct the force, thereby providing good side push support function.

[0006] In some embodiments, one of the accommodation spaces can be configured to connect the vehicle body longitudinal beam of the vehicle, and at least one accommodation space with a reinforcing structure is arranged on the outer side of the vehicle body longitudinal beam away from the center of the vehicle body.

[0007] In this way, the force of other external components connected by the frame body can be conducted to the vehicle body longitudinal beam, so that the vehicle body longitudinal beam can form good side push support function. Moreover, the frame structure composed of the frame body directly connecting a plurality of different external components can enhance the overall strength of the connection area between the vehicle body longitudinal beam and the joint device.

[0008] In some embodiments, the frame body comprises a first side wall, a second side wall, a third side wall and a fourth side wall connected in sequence, the first side wall, the second side wall and the third side wall are connected to different external components; the reinforcing member comprises a first reinforcing member and a plurality of second reinforcing members, wherein the first reinforcing member is located between the second side wall and the fourth side wall, one end of the first reinforcing member is connected to the first side wall and the other end is connected to the third side wall; the plurality of second reinforcing members are connected to the second side wall at one end and to the fourth side wall at the other end, and cross-connect with the first reinforcing member; at least two second reinforcing members, the first reinforcing member and the second side wall form a first accommodating space; the joint device further comprises a fixing plate arranged in the first accommodating space and connected to the first reinforcing member, the second reinforcing member and the second side wall.

[0009] The first reinforcing member and the second reinforcing member are cross-connected to form a cross-shaped structure in the internal space of the frame body, thereby enhancing the structural strength of the joint device, and at the same time, a plurality of regions surrounded by the side wall, the first reinforcing member and the second reinforcing member are formed in the internal space of the frame body, which can be used to receive and install external components, or additional reinforcing structures are added in the regions to improve the overall structural strength of the joint device.

[0010] In some embodiments, the first side wall is provided with a first fixing hole, the second side wall is provided with a second fixing hole, the third side wall is provided with a third fixing hole, and the fourth side wall is provided with a fourth fixing hole, and the second side wall and the fourth side wall are fixed to the same external component.

[0011] The second side wall and the fourth side wall are fixed to the same external component at the same time, which can enhance the strength of the external component fixation and thereby enhance the overall strength.

[0012] In some embodiments, the first fixing hole and the third fixing hole are threaded holes, and a metal threaded sleeve is embedded in the first fixing hole and the third fixing hole.

[0013] Embedding a metal threaded sleeve in the threaded hole can enhance the strength of the fixing hole and thereby improve the connection strength of the joint device.

[0014] In some embodiments, at least two second reinforcing members, the first reinforcing member and the fourth side wall form a second accommodating space adjacent to the first accommodating space, and a first reinforcing structure is arranged in the second accommodating space, and the first reinforcing structure is connected to the second reinforcing member, the first reinforcing member and the fourth side wall.

[0015] The second accommodating space is located at the side of the first accommodating space and is provided with the first reinforcing structure, which has a large strength, so that the joint device can bear and absorb a large impact force when the longitudinal beam is impacted from the side direction, and the impact force is easily transmitted to other components.

[0016] In some embodiments, the volume of the second accommodating space is greater than the volume of the first accommodating space.

[0017] This arrangement allows the joint device to contact the impact from the side direction of the longitudinal beam earlier, thereby transmitting and distributing the impact force and enhancing the side push support function.

[0018] In some embodiments, the joint device includes at least four second reinforcing members, which are sequentially arranged from the first side wall to the third side wall. The first second reinforcing member, the second second reinforcing member, and the second side wall and / or the third side wall form a third accommodating space, which is provided with a second reinforcing structure. Multiple third accommodating spaces are arranged on opposite sides of the first accommodating space and the second accommodating space.

[0019] This design allows multiple reinforcing structures to be arranged in the frame, thereby enhancing the overall strength of the joint device.

[0020] In some embodiments, the first side wall, the third side wall, and the second reinforcing member are arranged in parallel, and the second side wall, the fourth side wall, and the first reinforcing member are arranged in parallel.

[0021] This arrangement allows the joint device to have a more regular shape, with each accommodating space being a rectangular space, which better allows the reinforcing structure to be arranged or the external component to be accommodated.

[0022] In some embodiments, the depth of the portion of the first reinforcing member surrounding the first accommodating space is less than the length of the second side wall and the fourth side wall in the depth direction, and the first reinforcing member, the second reinforcing member, the first side wall, the second side wall, the third side wall, and the fourth side wall are located on the same plane along one side of the depth direction, and the fixing plate is connected to the side of the first reinforcing member away from the plane.

[0023] This arrangement allows the end of the longitudinal beam connecting the fixing plate to be located in the first accommodating space, and the smaller depth of the first reinforcing member allows the other side of the fixing plate to abut against the external component, and part of the external component is located between the second side wall and the fourth side wall, which is more easily connected to the second side wall and the fourth side wall.

[0024] In some embodiments, the surface of the fixing plate facing the plane is provided with a welding part.

[0025] The welding section allows the fixing plate to be welded to the longitudinal beam more effectively, enhancing the connection strength between the joint device and the longitudinal beam.

[0026] In some embodiments, the connector device further includes a bracket that connects the first reinforcement and / or the second reinforcement, the bracket being disposed along the width direction of the first reinforcement or the second reinforcement.

[0027] The bracket can enhance the strength of the first and / or second reinforcement members in the width direction, and can also connect other external components.

[0028] To solve the above-mentioned technical problems, another technical solution adopted in this application is: to provide a vehicle body, the vehicle body including longitudinal beams, energy-absorbing boxes, subframes, upper front cabin beams and joint devices, the joint devices being any of the joint devices described above, the subframes and the upper front cabin beams being connected to one of the side walls respectively, the longitudinal beams and the energy-absorbing boxes being located on opposite sides of the joint devices and connected to the opposite sides of the joint devices.

[0029] In this way, the joint device connects the longitudinal beam, energy-absorbing box, subframe, and upper front cabin beam simultaneously, so that the longitudinal beam, subframe, and upper front cabin beam form an integral frame structure with strong structural strength, capable of coping with and absorbing impact forces from all directions; when any part of this integral frame structure is subjected to force, the force can be transmitted to other components.

[0030] In some embodiments, a fixing plate is provided in one of the accommodating spaces, the longitudinal beam is connected to the fixing plate in the accommodating space, and at least one accommodating space with the reinforcing structure is arranged on the outer side of the longitudinal beam away from the center of the vehicle body.

[0031] In some embodiments, the energy-absorbing box is connected to the fixing plate.

[0032] This configuration allows the longitudinal beam and the energy-absorbing box to be connected by a fixing plate, and enables the transmission of impact force between the longitudinal beam and the energy-absorbing box.

[0033] In some embodiments, both the longitudinal beam and the energy-absorbing box are perpendicular to the fixed plate, and the area of ​​the surface where the longitudinal beam connects to the fixed plate is smaller than the area of ​​the surface where the energy-absorbing box connects to the fixed plate.

[0034] This configuration allows the vehicle body to use a larger energy-absorbing box, thereby achieving a better force dispersion effect.

[0035] In some implementations, the energy-absorbing box extends beyond the longitudinal beam in a direction away from the vehicle body.

[0036] Similarly, this configuration allows the vehicle body to use a larger energy-absorbing box, thereby achieving a better force dispersion effect. Attached Figure Description

Detailed Implementation

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings showing multiple embodiments according to this application. It should be understood that the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments described in this application without creative effort will fall within the scope of protection of this application.

[0046] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing specific embodiments only and is not intended to limit this application; the terms "comprising," "including," "having," "containing," etc., in the description, claims, and accompanying drawings of this application are open-ended terms. Therefore, "comprising," "including," or "having" refers to, for example, a method or apparatus having one or more steps or elements, but is not limited to having only these one or more elements. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0047] In the description of this application, it should be understood that the terms "center", "lateral", "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicate the orientation or positional relationship based on the orientation or positional relationship 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, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0048] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] In this application, the term "implementation" means that a specific feature, structure, or characteristic described in connection with an implementation can be included in at least one implementation of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same implementation, nor is it a separate or alternative implementation mutually exclusive with other implementations. Those skilled in the art will understand, explicitly and implicitly, that the implementations described in this application can be combined with other implementations.

[0050] As mentioned above, it should be emphasized that when the term "comprising / including" is used in this specification, it is used to explicitly indicate the presence of the stated feature, integer, step, or component, but does not exclude the presence or addition of one or more other features, integers, steps, components, or groups of features, integers, steps, or components. As used in this application, the singular forms "a," "an," and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0051] The terms “a” and “an” used in this specification may mean one, but may also be used interchangeably with “at least one” or “one or more”. The term “about” generally means the mentioned value plus or minus 10%, or more specifically, plus or minus 5%. The term “or” used in the claims means “and / or” unless it is explicitly stated that it refers only to alternatives.

[0052] 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, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0053] Existing joint devices typically connect only the longitudinal beams and the energy-absorbing box. They consist of two parts: the first part involves welding a first end plate to the longitudinal beam, and the second part involves welding a second end plate to the energy-absorbing box. The first and second end plates are then bolted together, thus connecting the longitudinal beam and the energy-absorbing box. This joint device design can meet the requirements for full-width frontal collisions, meaning it meets the requirements when colliding head-on with the longitudinal beam. However, in two-vehicle head-on collisions and center-pillar collisions, this joint device may fail, resulting in increased intrusion and increased injury to occupants. Furthermore, in side-impact collisions with the longitudinal beam, because there are no related structures on the sides, the longitudinal beam will make contact with the impact later, making it difficult to function effectively and failing to achieve a tandem side-thrust structure connecting the upper side beam of the front compartment, the longitudinal beam, and the subframe. Additionally, the spliced ​​end plate design, even when designed in series with the longitudinal beam, will lack overall strength and cannot form a good side-thrust support function.

[0054] To address the issue of insufficient overall strength and inability to provide adequate lateral thrust support in the longitudinal beams of the vehicle body, this application proposes a joint device. The joint device is box-shaped and employs a frame structure. The joint device includes four side walls that enclose an internal space. Within this internal space, at least one first reinforcing member extending along a first direction and at least one second reinforcing member extending along a second direction are provided. The ends of the first and second reinforcing members can be fixedly connected to any two of the four side walls, respectively. Thus, the connection between the first and second reinforcing members and the four side walls enhances the structural strength of the joint device and simultaneously creates multiple regions within the internal space of the joint device.

[0055] Preferably, the four sidewalls of the joint device form a square structure. The first reinforcing member is perpendicularly connected to a set of opposite sidewalls, and the second reinforcing member is perpendicularly connected to another set of opposite sidewalls. Thus, a grid-like structure is constructed in the internal space of the joint device, thereby forming multiple square areas. The first area is used to receive the end of the longitudinal beam and is fixedly connected to the longitudinal beam, for example, by welding, screwing, or riveting.

[0056] At least one reinforcing structure is provided in at least one of the other regions, and the reinforcing structure is fixedly connected to the sidewall of the region to form a reinforcing structure in the region, thereby enhancing the structural strength of the region.

[0057] On the side of the longitudinal beam, especially on the outer side of the longitudinal beam away from the center of the vehicle body, the joint device is provided with at least one area, which is used to receive the impact force in advance through the area on the outer side of the longitudinal beam when the outer side of the longitudinal beam away from the center of the vehicle body receives an impact or shock, and to transmit the impact force to the longitudinal beam, thereby increasing the buffer space on the outer side of the longitudinal beam away from the center of the vehicle body.

[0058] like Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional structural schematic diagram of the connector device 10 according to some embodiments. Figure 2 This is a front view of a connector device 10 according to some embodiments. In some embodiments, the connector device 10 includes a frame and a reinforcing member. The frame includes a plurality of sidewalls connected in sequence, forming an internal space within the frame. At least one sidewall is configured for connecting an external component. At least one reinforcing member is disposed within the internal space of the frame, connected to the sidewalls, forming a plurality of receiving spaces within the internal space of the frame, at least one of which is provided with a reinforcing structure.

[0059] The frame is a structure comprising multiple sequentially connected sidewalls, forming the outermost structure. These sidewalls, connected sequentially, are the main structural elements enclosing the frame. The interior of these sidewalls constitutes the internal space of the frame, while the exterior of the sidewalls connects to external components, enabling the connection between these external components and components within the frame's internal space, thus facilitating force transmission. Reinforcing structures, such as stiffeners, enhance the frame's structural strength. External components include, but are not limited to, the upper front cabin beam 40, the energy-absorbing box 30, the subframe 50, and the longitudinal beams 20. The frame can connect to any of these components, thereby enabling force transmission between the various external components.

[0060] Through the above methods, the frame can connect multiple external components and has a reinforced structure to enhance the structural strength of the frame, which can better transmit force and thus provide good lateral support function.

[0061] In some embodiments, one of the accommodating spaces can be configured to connect the vehicle body longitudinal beam 20, and at least one accommodating space with a reinforcing structure is arranged on the outer side of the vehicle body longitudinal beam 20 away from the center of the vehicle body.

[0062] In this way, the forces of other external components connected to the frame can be transmitted to the vehicle body longitudinal beam 20, enabling the vehicle body longitudinal beam 20 to form a good lateral thrust support function. Furthermore, the frame structure formed by directly connecting multiple different external components to the frame body enhances the overall strength of the connection area between the vehicle body longitudinal beam 20 and the joint device.

[0063] In some embodiments, the frame includes a first sidewall 11, a second sidewall 12, a third sidewall 13, and a fourth sidewall 14 connected sequentially. The fourth sidewall 14 connects to the third sidewall 13 and also to the first sidewall 11, thus forming a rectangular frame. The first sidewall 11, second sidewall 12, and third sidewall 13 are respectively connected to different external components. The reinforcing members include a first reinforcing member 15 and a plurality of second reinforcing members 16. The first reinforcing member 15 is located between the second sidewall 12 and the fourth sidewall 14, with one end connected to the first sidewall 11 and the other end connected to the third sidewall 13. The plurality of second reinforcing members 16 are connected at one end to the second sidewall 12 and at the other end to the fourth sidewall 14, and are cross-connected to the first reinforcing member 15. In this embodiment, four second reinforcing members 16 are included; in other embodiments, the second reinforcing members 16 include, but are not limited to, two, three, or more. The connector device 10 also includes a fixing plate 17, wherein, as... Figure 1As shown, portions of at least two second reinforcing members 16, portions of the first reinforcing member 15, and portions of the second sidewall 12 form a first accommodating space. Specifically, the portion of the first reinforcing member 15 located in the middle and between two adjacent second reinforcing members 16, the portions of two adjacent second reinforcing members 16 along the Z-direction located between the first reinforcing member 15 and the second sidewall 12, and the portion of the second sidewall 12 between the aforementioned two second reinforcing members 16 together form the first accommodating space. In some embodiments, four second reinforcing members 16 are arranged along the Z-direction, and portions of two adjacent second reinforcing members 16 located in the middle along the Z-direction can be selected to form the first accommodating space. In this embodiment, the Z-direction is the longitudinal length direction of the connector device 10. The first accommodating space is not a sealed space but a space with an opening. A fixing plate 17 is disposed in the first accommodating space and connected to the first reinforcing member 15, the second reinforcing member 16, and the second sidewall 12. In some embodiments, the fixing plate 17 is perpendicular to the first reinforcing member 15, the second reinforcing member 16, and the second sidewall 12.

[0064] The first reinforcing member 15 and the second reinforcing member 16 are connected to each other in a cross shape, forming a grid-like structure in the internal space of the frame, thereby enhancing the structural strength of the connector device 10. At the same time, multiple areas are constructed in the internal space of the frame, which are enclosed by the side walls, the first reinforcing member 15, and the second reinforcing member 16. These areas can be used to receive and install external components, or to add reinforcing structures in the areas to improve the overall structural strength of the connector device 10.

[0065] The first sidewall 11, second sidewall 12, third sidewall 13, and fourth sidewall 14 are strip-shaped or plate-shaped structures used to form the frame. The connection methods between the first sidewall 11, second sidewall 12, and third sidewall 13 and external components include, but are not limited to, welding, bolting, riveting, and snap-fitting. The first reinforcing member 15 is also a strip-shaped or plate-shaped structure, but it is located inside the frame, serving a supporting and separating function. The second reinforcing member 16 is also a strip-shaped or plate-shaped structure, located inside the frame, serving a supporting and separating function. The difference between the second reinforcing member 16 and the first reinforcing member 15 is that their orientations are different. The fixing plate 17 is a plate-shaped structure used to connect the longitudinal beam 20. In some embodiments, the frame, the first reinforcing member 15, and the second reinforcing member 16 are integrally formed structures, or the frame, the first reinforcing member 15, the second reinforcing member 16, and the fixing plate 17 are integrally formed structures and are made of metal. The metal includes, but is not limited to, aluminum alloy, steel, and steel alloy.

[0066] By setting the first reinforcing member 15, the frame of the joint device 10 is divided into two parts, so that one side of the fixing plate 17 still has a portion of the frame. The fixing plate 17 is used to connect the longitudinal beam 20, thus ensuring that the side of the longitudinal beam 20 still has a portion of the frame. When a collision occurs on the side of the longitudinal beam 20, the force is transmitted to the longitudinal beam 20 through the frame, providing good lateral thrust support. Furthermore, the frame directly connects multiple different external components, forming a frame structure that enhances the overall strength of the connection area between the vehicle body longitudinal beam 20 and the joint device.

[0067] In some embodiments, a first fixing hole 111 is provided on the first sidewall 11, a second fixing hole 121 is provided on the second sidewall 12, a third fixing hole 131 is provided on the third sidewall 13, and a fourth fixing hole is provided on the fourth sidewall 14. The second sidewall 12 and the fourth sidewall 14 can be used to fix the same external component.

[0068] The first fixing hole 111, the second fixing hole 121, the third fixing hole 131, and the fourth fixing hole are configured to fix the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 to an external component via fasteners. Any two of the first fixing holes 111, 121, 131, and 4 can be the same or different. There can be one, two, or more first fixing holes 111, depending on actual needs. Similarly, there can be one, two, or more second fixing holes 121, 131, and 4 fixing holes. Furthermore, although the second sidewall 12 and the fourth sidewall 14 can be used to fix the same external component, the second fixing hole 121 and the fourth fixing hole can be the same or different. Different styles of second fixing holes 121 and fourth fixing holes can be used to cooperate with different styles of fasteners, allowing for multi-style fixing of the external component and thus enhancing the fixing effect.

[0069] The second sidewall 12 and the fourth sidewall 14 are fixed with the same external components at the same time, which can enhance the strength of the external component fixing, thereby enhancing the overall strength.

[0070] In some embodiments, the first fixing hole 111 and the third fixing hole 131 are threaded holes, and metal threaded sleeves are embedded in the first fixing hole 111 and the third fixing hole 131.

[0071] A metal threaded sleeve is a tubular metal structure with threads on both its inner and outer sides. The external thread of the metal threaded sleeve is screwed into the internal threads of the first fixing hole 111 and the third fixing hole 131. The internal thread of the metal threaded sleeve is used to screw into external components or fasteners, thereby achieving a fixed connection between the external components or fasteners and the connector device. Metal threaded sleeves include, but are not limited to, steel threaded sleeves, steel alloy threaded sleeves, copper threaded sleeves, and copper alloy threaded sleeves. The hardness of the metal threaded sleeve needs to be greater than the hardness of the first sidewall 11 and the third sidewall 13, thereby improving the structural strength and connection strength of the first fixing hole 111 and the third fixing hole 131, and preventing damage to the first fixing hole 111 and the third fixing hole 131 during collisions.

[0072] Embedding a metal threaded sleeve in the threaded hole can enhance the strength of the fixing hole, thereby improving the connection strength of the connector device 10.

[0073] In some implementations, such as Figures 1-2 As shown, at least two portions of the second reinforcing members 16, a portion of the first reinforcing member 15, and a portion of the fourth sidewall 14 enclose a second accommodating space 18. The second accommodating space 18 is adjacent to the first accommodating space. A first reinforcing structure 181 is provided in the second accommodating space 18, and the first reinforcing structure 181 can be fixedly connected to the sidewall of the second accommodating space 18. Specifically, the first reinforcing structure can connect the second reinforcing members 16, the first reinforcing member 15, and the fourth sidewall 14.

[0074] The portion of the first reinforcing member 15 between two adjacent second reinforcing members 16 in the middle position, the portion of the two adjacent second reinforcing members 16 in the middle position between the first reinforcing member 15 and the fourth sidewall 14, and the portion of the fourth sidewall 14 between two adjacent second reinforcing members 16 in the middle position form a second accommodating space 18. In this embodiment, the first accommodating space and the second accommodating space 18 are enclosed by the same two second reinforcing members 16, but different portions of these two second reinforcing members 16 respectively enclose the first accommodating space and the second accommodating space 18. The portions of the first reinforcing members 15 that enclose the first accommodating space and the second accommodating space 18 are the same. Therefore, the first accommodating space and the second accommodating space 18 are adjacent. The second accommodating space 18 is also not a sealed space, but a space with an opening. The first reinforcing structure 181 may be formed by multiple strip-shaped structures or plate-shaped structures intersecting, connecting the four corners of the second accommodating space 18 and the fourth sidewall 14 and the first reinforcing member 15. Alternatively, the first reinforcing structure 181 may connect only to the four corners of the second accommodating space 18; or the first reinforcing structure 181 may connect to the two second reinforcing members 16. When the first reinforcing structure 181 connects to the fourth sidewall 14, the first reinforcing member 15, or the second reinforcing member 16, it is best to divide the fourth sidewall 14, the first reinforcing member 15, or the second reinforcing member 16 that enclose the second accommodating space 18 equally, so that the fourth sidewall 14, the first reinforcing member 15, or the second reinforcing member 16 are subjected to uniform force. The intersection of the multiple strip-shaped or plate-shaped structures in the first reinforcing structure 181 is preferably the center position of the second accommodating space 18. In addition, the first reinforcing structure 181 includes, but is not limited to, this structure, and may also be a row structure, a honeycomb structure, or a structure in which multiple triangles or trapezoids are arranged in an alternating pattern.

[0075] The second accommodating space 18 is located to the side of the first accommodating space and is provided with a first reinforcing structure 181, which has high strength. This allows the joint device 10 to withstand and absorb a large impact force when subjected to an impact force along the side of the longitudinal beam 20, and to easily transmit the impact force to other components.

[0076] In some embodiments, the volume of the second accommodating space 18 is larger than the volume of the first accommodating space.

[0077] The second accommodating space 18 shares a portion of the first reinforcing member 15 with the first accommodating space. Therefore, its volume is determined by the length of the second reinforcing member 16 that encloses both the first and second accommodating spaces 18. The volume of the second accommodating space 18 is greater than that of the first accommodating space, meaning the length of the portion of the second reinforcing member 16 enclosing the second accommodating space 18 is greater than the length of the portion of the second reinforcing member 16 enclosing the first accommodating space. The length direction of the second reinforcing member 16 is parallel to the lateral direction of the longitudinal beam 20. The first accommodating space is used to accommodate the fixing plate 17 connecting the longitudinal beam 20. Therefore, the second accommodating space 18 is provided to increase the collision distance in the lateral direction of the longitudinal beam 20, i.e., to increase the collision distance of the longitudinal beam 20 in the Y direction. This allows the joint device 10 to collide earlier when the longitudinal beam 20 collides laterally, especially the second accommodating space 18 portion of the joint device 10, thereby transmitting force to the longitudinal beam 20 and enabling the longitudinal beam 20 to participate in the collision earlier. Alternatively, in other embodiments, an extended portion with the same structure can also be provided on the other side of the first accommodating space. However, under normal circumstances, the longitudinal beam 20 is positioned on the transverse side of the vehicle body. Therefore, in order to receive collisions from outside the vehicle body, this structure can be provided on the side of the longitudinal beam 20 away from the center of the vehicle body.

[0078] This configuration allows the joint device 10 to come into contact with the impact in the lateral direction of the longitudinal beam 20 earlier, thereby transmitting and distributing the impact force and enhancing the lateral thrust support function of the longitudinal beam end area.

[0079] In some embodiments, the connector device 10 includes at least four second reinforcing members 16, which are arranged sequentially. From the first sidewall 11 to the third sidewall 13 (the opposite direction of the Z direction), the first second reinforcing member 16, the second second reinforcing member 16, and the second sidewall 12 and / or the third sidewall 13 form a third accommodating space 19, in which a second reinforcing structure 191 is provided. From the third sidewall 13 to the first sidewall 11 (the Z direction), the first second reinforcing member 16, the second second reinforcing member 16, and the second sidewall 12 and / or the third sidewall 13 also form a third accommodating space 19, in which a second reinforcing structure 191 is provided. There are multiple third accommodating spaces 19, located on opposite sides of the first and second accommodating spaces 18.

[0080] The first and second accommodating spaces 18 are arranged along the extension direction of the second reinforcing member 16, i.e., the first and second accommodating spaces 18 are arranged along the Y direction. The Y direction is the transverse length direction of the connector device 10. The third accommodating space 19 is located in the first and second accommodating spaces 18 along the Z direction and / or the opposite direction of the Z direction. The arrangement of the third accommodating space 19 separates the first fixing hole 111 and the third fixing hole 131 from the first and second accommodating spaces 18. Thus, when the connector device 10 receives an external impact, especially when the external component connected to the first side plate 11 and the third side plate 13 is subjected to force, it can be buffered and absorbed by the second reinforcing structure 191 in the third accommodating space 19 before being transmitted to the longitudinal beam 20, thereby enhancing the overall strength of the connector device 10. The second reinforcing structure 191 can be formed by two intersecting strip structures or plate structures, respectively connecting the four corners of the third accommodating space 19, and the intersection point is located at the center of the third accommodating space 19. The second reinforcing structure 191 can also be the same as the first reinforcing structure 181, formed by the intersection of multiple strip-shaped or plate-shaped structures, or by a row-and-column structure, honeycomb structure, or multiple triangles or trapezoids arranged in an alternating pattern. The first reinforcing structure 181 and the second reinforcing structure 191 can also be reinforcing ribs. In some embodiments, the first reinforcing structure 181 and the second reinforcing structure 191 are also integrally formed with the frame, the first reinforcing member 15, and the second reinforcing member 16. Additionally, chamfered structures can be provided at the four corners of the second accommodating space 18 and the third accommodating space 19.

[0081] This design allows for multiple reinforcing structures within the frame, thereby enhancing the overall strength of the joint device 10.

[0082] In some embodiments, the first sidewall 11, the third sidewall 13 and the second reinforcing member 16 are arranged in parallel, and the second sidewall 12, the fourth sidewall 14 and the first reinforcing member 15 are arranged in parallel.

[0083] In some embodiments, the first sidewall 11, the third sidewall 13, and the second reinforcing member 16 are perpendicular to the second sidewall 12, the fourth sidewall 14, and the first reinforcing member 15.

[0084] This arrangement allows the connector device 10 to have a more regular shape, with each accommodating space being a rectangular space, which better facilitates the installation of reinforcing structures or the accommodation of external components.

[0085] Alternatively, the first sidewall 11, the third sidewall 13, and the second reinforcing member 16 are not perpendicular to the second sidewall 12, the fourth sidewall 14, and the first reinforcing member 15, forming an acute or obtuse angle.

[0086] In some implementations, such as Figure 1As shown, in the X direction, i.e., the depth direction of the connector device 10, the depth of the first accommodating space formed by the first reinforcing member 15 and the fixing plate 17 is less than the lengths of the second sidewall 12 and the fourth sidewall 14 in that depth direction. The first reinforcing member 15, the second reinforcing member 16, the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 have the same length in the X direction, i.e., the same length in that depth direction, and the first reinforcing member 15, the second reinforcing member 16, the first sidewall 11, the second sidewall 12, the third sidewall 13, and the fourth sidewall 14 are located on the same plane along one side of that depth direction. The fixing plate 17 is connected to the side of the first reinforcing member 15 away from this plane.

[0087] Figure 1 and Figure 2 In the diagram, the X direction represents the depth of the connector device 10, the Y direction represents the lateral length of the connector device 10, and the Z direction represents the longitudinal length of the connector device 10. The depth directions of the first reinforcing member 15, the second reinforcing member 16, the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 are also defined as the X direction. Assuming the plane containing this plane is the front of the frame and the plane opposite to this plane is the back of the frame, the longitudinal beam 20 is inserted from the front of the frame, i.e., inserted into the first accommodating space along the opposite direction of the X direction and connected to the fixing plate 17. The energy-absorbing box 30 is connected to the connector device 10 on the back of the frame, i.e., connected along the X direction, and connected to the first reinforcing member 15, the second reinforcing member 16, or the fixing plate 17. The fixing plate 17 is located on the side of the first accommodating space facing the back of the frame. The first reinforcing member 15 and the second reinforcing member 16 are shorter in the depth direction, which means they occupy less space in the X direction. This allows a larger energy-absorbing box 30 to be inserted into the frame without being blocked by the first reinforcing member 15 or the second reinforcing member 16.

[0088] This arrangement allows the end of the longitudinal beam 20 connected to the fixing plate 17 to be located in the first accommodating space, while the shorter length of the first reinforcing member 15 in the X direction allows the other side of the fixing plate 17 to contact the external component. Furthermore, part of the external component is located between the second side wall 12 and the fourth side wall 14, making it easier to connect with the second side wall 12 and the fourth side wall 14.

[0089] In some embodiments, alternatively, the lengths of the first reinforcing member 15 and the second reinforcing member 16 in the X direction are the same as the lengths of the second sidewall 12 and the fourth sidewall 14 in the X direction. The energy-absorbing box 30 can be connected to the first reinforcing member 15, the second reinforcing member 16, the second sidewall 12, and the fourth sidewall 14. This allows the energy-absorbing box 30 to have a larger width in the Y direction, so that when a collision occurs in the lateral direction of the longitudinal beam, the energy-absorbing box 30 can absorb energy in the Y direction earlier, thereby improving the lateral support capacity.

[0090] In some embodiments, the surface of the fixing plate 17 facing the plane is provided with a welding part 171.

[0091] The welding portion 171 includes, but is not limited to, strip-shaped protrusions and dot-shaped protrusions. Multiple welding portions 171 may be provided and distributed in a dispersed manner. Multiple welding portions 171 may be grouped together, and multiple groups may be provided. In some embodiments, the other side surface of the fixing plate 17 may also be provided with welding portions 171 for welding to the energy-absorbing box 30.

[0092] The welding part 171 allows the fixing plate 17 to be welded to the longitudinal beam 20 more effectively, thereby enhancing the connection strength between the joint device 10 and the longitudinal beam 20.

[0093] In some embodiments, the connector device 10 further includes a bracket 101, which connects the first reinforcing member 15 and / or the second reinforcing member 16. The bracket 101 is a protruding structure, which may be provided with connection holes for connecting a fan or other external components. Alternatively, in some embodiments, the bracket 101 may also serve as an auxiliary support.

[0094] The bracket 101 can enhance the strength of the first reinforcing member 15 and / or the second reinforcing member 16, and can also connect other external components.

[0095] like Figure 3 and Figure 4 As shown, Figure 3 This is a three-dimensional structural diagram of a vehicle body according to some embodiments. Figure 4 This is a left view of a vehicle body according to some embodiments. The vehicle body includes longitudinal beams 20, energy-absorbing boxes 30, subframes 50, upper front cabin beams 40, and connector devices 10. The connector device 10 is the connector device 10 in any of the above embodiments. The subframes 50 and the upper front cabin beams 40 are respectively connected to one of the side walls, and the longitudinal beams 20 and energy-absorbing boxes 30 are located on opposite sides of the connector device 10 and connected to the opposite sides of the connector device 10.

[0096] In the above manner, the joint device 10 simultaneously connects the longitudinal beam 20, the energy-absorbing box 30, the subframe 50, and the upper beam 40 of the front compartment, so that the longitudinal beam 20, the subframe 50, and the upper beam 40 of the front compartment form an integral frame structure with strong structural strength, capable of coping with and absorbing impact forces from all directions; when any part of the integral frame structure is subjected to force, the force can be transmitted to other components.

[0097] In some embodiments, a fixing plate 17 is provided in a accommodating space, and a longitudinal beam 20 is connected to the fixing plate 17 in the accommodating space. At least one accommodating space with a reinforcing structure is arranged on the outer side of the longitudinal beam away from the center of the vehicle body.

[0098] This method makes the connection between the longitudinal beam 20 and the joint device 10 more stable, and the joint device 10 can better transmit the force to the longitudinal beam 20 after being subjected to force.

[0099] In some embodiments, the energy-absorbing box 30 is connected to the fixing plate 17.

[0100] This method allows the energy-absorbing box 30 and the longitudinal beam 20 to be connected through the fixing plate 17, making the connection between the energy-absorbing box 30 and the longitudinal beam 20 more stable.

[0101] In some embodiments, both the longitudinal beam 20 and the energy-absorbing box 30 are perpendicular to the fixing plate 17. The area of ​​the longitudinal beam 20 on the surface connected to the fixing plate 17 is smaller than the area of ​​the energy-absorbing box 30 on the surface connected to the fixing plate 17.

[0102] Both the longitudinal beam 20 and the energy-absorbing box 30 are perpendicular to the fixed plate 17, and are located on opposite sides of the fixed plate 17. Therefore, the surfaces connecting the longitudinal beam 20 and the fixed plate 17 are opposite sides of the fixed plate 17 to the surfaces connecting the energy-absorbing box and the fixed plate 17. The larger the surface connecting the energy-absorbing box 30 and the fixed plate 17, the larger the energy-absorbing box 30. That is, in the YZ plane, the area of ​​the energy-absorbing box 30 is larger than the area of ​​the longitudinal beam 20. Therefore, in the Y direction, that is, in the lateral direction of the longitudinal beam 2 away from the center of the vehicle body, the energy-absorbing box 30 still has a partial extension. Since the energy-absorbing box 30 still has a partial extension on the side of the longitudinal beam 20, a larger energy-absorbing box 30 can be used, and both sides can be connected to the connector device 10, and it is not limited to an energy-absorbing box 30 with the same cross-sectional size as the longitudinal beam 20.

[0103] This configuration allows the vehicle body to use a larger energy-absorbing box 30, thereby achieving a better force dispersion effect.

[0104] In some implementations, the energy-absorbing box 30 extends beyond the longitudinal beam 20 in a direction away from the vehicle body.

[0105] Similarly, this configuration is also intended to allow the vehicle body to use a larger energy-absorbing box 30, thereby achieving a better force dispersion effect.

[0106] In the above embodiment, each accommodating space can be regarded as a region. The connector device 10 is surrounded by four side walls to form the internal space of the connector device 10, and is divided into multiple regions by the first reinforcing member 15 and the second reinforcing member 16. The first accommodating space is the first region.

[0107] In some specific application scenarios, addressing the issue of insufficient overall strength and inability to provide adequate lateral thrust support in existing vehicle body longitudinal beams 20, the connector device 10 of this application includes a frame, a first reinforcing member 15, four second reinforcing members 16, and a fixing plate 17. The frame includes a first sidewall 11, a second sidewall 12, a third sidewall 13, and a fourth sidewall 14 connected sequentially. The fourth sidewall 14 connects to both the third sidewall 13 and the first sidewall 11, forming a rectangular frame. The first sidewall 11, second sidewall 12, and third sidewall 13 are connected to different external components. The first reinforcing member 15 is connected at one end to the first sidewall 11 and at the other end to the third sidewall 13, and is positioned between the second sidewall 12 and the fourth sidewall 14. The four second reinforcing members 16 are connected at one end to the second sidewall 12 and at the other end to the fourth sidewall 14, and are cross-connected to the first reinforcing members 15, with the four second reinforcing members 16 parallel to each other. A portion of the two middle second reinforcing members 16, a portion of the first reinforcing member 15, and a portion of the second sidewall 12 form a first accommodating space. Specifically, the portion of the first reinforcing member 15 between the two adjacent second reinforcing members 16 in the middle position, the portion of the two adjacent second reinforcing members 16 in the middle position between the first reinforcing member and the second sidewall 12, and the portion of the second sidewall 12 between the two adjacent second reinforcing members 16 in the middle position all form the first accommodating space. The first accommodating space is not a sealed space but rather a space with an opening. A fixing plate 17 is disposed in the first accommodating space and connected to the first reinforcing member 15, the second reinforcing member 16, and the second sidewall 12. The fixing plate 17 is perpendicular to the first reinforcing member 15, the second reinforcing member 16, and the second sidewall 12. In some embodiments, a portion of the two middle second reinforcing members 16, a portion of the first reinforcing member 15, and a portion of the fourth sidewall 14 form a second accommodating space 18. The second accommodating space 18 is adjacent to the first accommodating space. The second accommodating space 18 is provided with a first reinforcing structure 181, which connects the second reinforcing member 16, the first reinforcing member 15 and the fourth side wall 14.

[0108] By setting the first reinforcing member 15, the frame of the joint device 10 is divided into two parts, so that one side of the fixing plate 17 still has a portion of the frame. The fixing plate 17 is used to connect the longitudinal beam 20, thus ensuring that the side of the longitudinal beam 20 away from the center of the vehicle body still has a portion of the frame. When a collision occurs on the side of the longitudinal beam 20, the force is transmitted to the longitudinal beam 20 through the frame, thus providing good lateral thrust support. Furthermore, the frame directly connects multiple different external components, enhancing the overall strength of the relevant parts of the vehicle body longitudinal beam 20.

[0109] Although in the above embodiment, the first reinforcing member 15 is connected to the first sidewall and the third sidewall, and the second reinforcing member 16 is connected to the second sidewall and the fourth sidewall, alternatively, the first reinforcing member 15 may be connected to only one of the first sidewall and the third sidewall, while the other end of the first reinforcing member 15 is connected to the second reinforcing member 16; and / or, the second reinforcing member 16 may be connected to only one of the second sidewall and the fourth sidewall, while the other end of the second reinforcing member 16 is connected to the first reinforcing member 15. Thus, regions of different sizes and positions can be constructed in the internal space of the joint device 10 to accommodate various different requirements.

[0110] Although the frame includes a first sidewall, a second sidewall, a third sidewall, and a fourth sidewall in the above embodiments, this application is not limited thereto. Alternatively, the frame may include three, five, six, or other numbers of sidewalls. Within the frame space enclosed by the sidewalls, the reinforcing members can be connected to the corresponding sidewalls as required by the design, and different connection structures can be constructed between the reinforcing members as needed.

[0111] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
