Description

Joint device and vehicle body

[0001] This application claims priority to Chinese patent application No. 2023108013070, filed on June 30, 2023, entitled “Connector device and vehicle body,” which is incorporated herein by reference in its entirety.

Technical field

[0002] The present application relates to the field of automobile parts, and in particular to a joint device and a vehicle body. [Background Technology]

[0003] In some vehicles, such as gasoline-powered, electric, or hybrid vehicles, a joint device is required to connect the longitudinal beam to the crash box. For vehicle safety reasons, the longitudinal beam, crash box, and joint device must meet the safety requirements for full-width head-on collisions, two-vehicle collisions, and frontal center impacts with poles. However, in sideways collisions, the longitudinal beam is less effective. Therefore, using existing joint devices results in insufficient overall strength in the longitudinal beam-related parts of the vehicle body and inability to provide adequate side thrust support.

[0004] [Summary of the invention]

[0005] The present application provides a joint device and a vehicle body, which can solve the problem that the overall strength of the relevant parts of the vehicle body longitudinal beam is insufficient and cannot provide a good side thrust support function.

[0006] In order to solve the above technical problems, a technical solution adopted in this application is: to provide a joint device, which includes: a frame, including multiple side walls connected in sequence, and an internal space of the frame is formed inside the multiple side walls; at least one side wall is configured to be used for connecting external components; at least one reinforcement member is configured in the internal space of the frame, and the reinforcement member is connected to the side wall to form multiple accommodating spaces in the internal space of the frame, and at least one of the accommodating spaces is provided with a reinforcement structure.

[0007] In the above manner, the frame can realize the connection between multiple external components, and has a reinforcement structure to enhance the structural strength of the frame, which can better transmit the force, thereby providing a good side push support function.

[0008] In some embodiments, one of the accommodating spaces can be configured to be connected to a vehicle body longitudinal beam, and at least one accommodating space having a reinforcement structure is arranged on an outer side of the vehicle body longitudinal beam away from a center of the vehicle body.

[0009] This method transfers force from other external components connected to the frame to the vehicle's longitudinal beams, enabling them to effectively support side thrusts. Furthermore, the frame directly connects multiple external components to form a framework structure, enhancing the overall strength of the area where the longitudinal beams connect to the joint device.

[0010] In some embodiments, the frame includes a first side wall, a second side wall, a third side wall and a fourth side wall connected in sequence, and the first side wall, the second side wall and the third side wall are connected to different external components; the reinforcement includes a first reinforcement and multiple second reinforcements, wherein the first reinforcement is located between the second side wall and the fourth side wall, one end is connected to the first side wall, and the other end is connected to the third side wall; multiple second reinforcements, one end is connected to the second side wall, the other end is connected to the fourth side wall, and are cross-connected with the first reinforcement, at least two second reinforcements, the first reinforcement and the second side wall form a first accommodating space; the joint device also includes a fixing plate, which is arranged in the first accommodating space and connected to the first reinforcement, the second reinforcement and the second side wall.

[0011] The first reinforcement member and the second reinforcement member are cross-connected to each other, forming a crisscross structure in the internal space of the frame, thereby enhancing the structural strength of the joint device. At the same time, multiple areas surrounded by side walls, first reinforcement members, and second reinforcement members are constructed in the internal space of the frame. These areas can be used to receive and install external components, or reinforcement structures can be added in the areas to improve the overall structural strength of the joint device.

[0012] In some embodiments, a first fixing hole is provided on the first side wall, a second fixing hole is provided on the second side wall, a third fixing hole is provided on the third side wall, and a fourth fixing hole is provided on the fourth side wall, and the second side wall and the fourth side wall are fixed to the same external component.

[0013] The second side wall and the fourth side wall are fixed with the same external component at the same time, which can enhance the fixing strength of the external component and thus enhance the overall strength.

[0014] In some embodiments, the first fixing hole and the third fixing hole are threaded holes, and metal threaded sleeves are embedded in the first fixing hole and the third fixing hole.

[0015] Embedding a metal threaded sleeve in a threaded hole can enhance the strength of the fixing hole, thereby improving the connection strength of the joint device.

[0016] In some embodiments, at least two of the second reinforcement members, the first reinforcement member and the fourth side wall form a second accommodating space adjacent to the first accommodating space, and a first reinforcement structure is provided in the second accommodating space, which connects the second reinforcement member, the first reinforcement member and the fourth side wall.

[0017] The second accommodating space is located to the side of the first accommodating space and is provided with a first reinforcing structure, which has greater strength, so that when the joint device is subjected to impact force from the side of the longitudinal beam, it can withstand and absorb greater impact force and easily transmit the impact force to other components.

[0018] In some embodiments, the volume of the second accommodating space is greater than the volume of the first accommodating space.

[0019] This arrangement enables the joint device to be exposed to impacts from the side of the longitudinal beam earlier, thereby transmitting and distributing the impact force and enhancing the side thrust support function.

[0020] In some embodiments, the joint device includes at least four second reinforcement members, and the at least four second reinforcement members are arranged in sequence, from the first side wall to the third side wall, the first second reinforcement member, the second second reinforcement member, and the second side wall and / or the third side wall form a third accommodating space, and a second reinforcement structure is provided in the third accommodating space; multiple third accommodating spaces are arranged on opposite sides of the first accommodating space and the second accommodating space.

[0021] This design approach enables the frame to have multiple reinforcement structures, thereby enhancing the overall strength of the connector device.

[0022] In some embodiments, the first side wall, the third side wall, and the second reinforcement are arranged in parallel, and the second side wall, the fourth side wall, and the first reinforcement are arranged in parallel.

[0023] This arrangement can make the shape of the connector device more regular, and each accommodating space is a rectangular space, which is better for arranging reinforcement structures or accommodating external components.

[0024] In some embodiments, the depth of the portion of the first accommodating space enclosed by the first reinforcement is less than the length of the second side wall and the fourth side wall in the depth direction, and the first reinforcement, the second reinforcement, 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 reinforcement away from the plane.

[0025] This arrangement allows the end portion of the longitudinal beam connected to the fixing plate to be located in the first accommodating space, and the smaller depth of the first reinforcement allows the other side of the fixing plate to contact the external component, and part of the external component is located between the second side wall and the fourth side wall, making it easier to connect with the second side wall and the fourth side wall.

[0026] In some embodiments, a welding portion is provided on a surface of the fixing plate facing the plane.

[0027] The provision of the welding portion can enable the fixing plate to be better welded to the longitudinal beam, thereby enhancing the connection strength between the joint device and the longitudinal beam.

[0028] In some embodiments, the joint device further includes a bracket, the bracket connecting the first reinforcement member and / or the second reinforcement member, and the bracket is arranged along the width direction of the first reinforcement member or the second reinforcement member.

[0029] The provision of the bracket can enhance the strength of the first reinforcement and / or the second reinforcement in the width direction, and can also connect other external components.

[0030] In order to solve the above technical problems, another technical solution adopted in this application is: providing a vehicle body, which includes a longitudinal beam, an energy absorption box, a subframe, a front cabin upper side beam and a joint device, and the joint device is any one of the joint devices described above, the subframe and the front cabin upper side beam are respectively connected to one of the side walls, the longitudinal beam and the energy absorption box are respectively located on opposite sides of the joint device, and are connected to opposite sides of the joint device.

[0031] In the above manner, the joint device simultaneously connects the longitudinal beam, energy absorption box, subframe and front cabin upper side beam, so that the longitudinal beam, subframe and front cabin upper side beam form an integral frame structure with strong structural strength, which can cope with and absorb impact forces in all directions; when any point in the overall frame structure is subjected to force, the force can be transmitted to other components.

[0032] 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 having the reinforcing structure is arranged on the outer side of the longitudinal beam away from the center of the vehicle body.

[0033] In some embodiments, the energy absorption box is connected to the fixing plate.

[0034] With this arrangement, the longitudinal beam and the energy absorption box can be connected through the fixing plate and the impact force can be transmitted between the longitudinal beam and the energy absorption box.

[0035] In some embodiments, the longitudinal beam and the energy absorbing box are both perpendicular to the fixing plate, and the area of ​​the surface where the longitudinal beam is connected to the fixing plate is smaller than the area of ​​the surface where the energy absorbing box is connected to the fixing plate.

[0036] This setting allows the vehicle body to use a larger energy absorption box, thereby achieving a better force dispersion effect.

[0037] In some embodiments, the crash box extends beyond the longitudinal beam in a direction away from the vehicle body.

[0038] Similarly, this setting allows the vehicle body to use a larger energy absorption box, thereby achieving a better force dispersion effect.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed to indicate or imply relative importance or to implicitly specify the number of the technical features indicated. Thus, a feature designated "first" or "second" may explicitly or implicitly include one or more of the features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0049] In the description of the present application, it should be understood that the terms "center", "lateral", "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0050] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0051] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it refer to independent or alternative embodiments that are mutually exclusive with other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0052] As mentioned above, it should be emphasized that when the term "include / comprises" is used in this specification, it is used to clearly indicate the presence of the features, integers, steps or components, but does not exclude the presence or addition of one or more other features, integers, steps, components or groups of features, integers, steps, components. As used in this application, the singular forms "a", "an" and "the" also include the plural forms, unless the context clearly indicates otherwise.

[0053] The terms "a" and "an" used in this specification may mean one, but may also have the same meaning as "at least one" or "one or more." The term "about" generally means plus or minus 10%, or more specifically, plus or minus 5%, of the referenced value.

[0054] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0055] Existing joint devices generally only connect the longitudinal beam and the energy absorption box. It is divided into two parts. The first part is the first end plate welded to the longitudinal beam, and the second part is the second end plate welded to the energy absorption box. The first end plate and the second end plate are then bolted together to connect the longitudinal beam and the energy absorption box. The design of this joint device can meet the requirements of full-width head-on collision, that is, it can meet the requirements when a collision occurs on the front of the longitudinal beam. However, in the case of a double-vehicle collision and a center column collision, this joint device will fail to connect, resulting in an increase in the amount of intrusion and increased damage to the members. In addition, in the case of a side collision of the longitudinal beam, since there is no related structure on the side of the longitudinal beam, the longitudinal beam will be exposed to the collision later, making it difficult to play a role, and it is impossible to realize an integrated side thrust structure in which the front cabin upper side beam, the longitudinal beam, and the subframe are connected in series. In addition, the end plate splicing design, even if it is designed as a series structure with the longitudinal beam, will lack overall strength and cannot form a good side thrust support function.

[0056] In order to solve the problem of insufficient overall strength of the relevant parts of the vehicle body longitudinal beam and the inability to form a good side thrust support function, the present application proposes a joint device, which is box-shaped and adopts a frame structure; the joint device includes four side walls, and the four side walls surround the internal space of the joint device. At least one first reinforcement extending along the first direction and at least one second reinforcement extending along the second direction are arranged in the internal space. The two ends of the first reinforcement and the second reinforcement can be fixedly connected to any two of the four side walls respectively. Therefore, through the connection of the first reinforcement, the second reinforcement and the four side walls, the structural strength of the joint device can be enhanced, and multiple areas can be formed in the internal space of the joint device.

[0057] Preferably, the four side walls of the joint device form a square structure, the first reinforcement member is perpendicularly connected to one set of opposing side walls, and the second reinforcement member is perpendicularly connected to another set of opposing side walls. Thus, a crisscross pattern is constructed within the interior space of the joint device, thereby forming a plurality of 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.

[0058] At least one reinforcement structure is provided in at least one of the other regions, and the reinforcement structure is fixedly connected to the side wall of the region where it is located to form a reinforcement structure in the region, thereby enhancing the structural strength of the region.

[0059] On the side relative to 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 a collision or impact, and 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.

[0060] As shown in Figures 1 and 2, Figure 1 is a schematic diagram of the three-dimensional structure of the connector device 10 according to some embodiments, and Figure 2 is a front view of the connector device 10 according to some embodiments. In some embodiments, the connector device 10 includes a frame and a reinforcement. The frame includes a plurality of side walls connected in sequence, and the plurality of side walls form an internal space of the frame. At least one side wall is configured for connecting external components. There is at least one reinforcement, which is configured in the internal space of the frame. The reinforcement is connected to the side wall to form a plurality of accommodating spaces in the internal space of the frame, and a reinforcement structure is provided in at least one of the accommodating spaces.

[0061] The frame is a structure including a plurality of side walls connected in sequence, which serves as the outermost structure. The plurality of side walls are connected in sequence and are the main structure that encloses the frame. The interior of the plurality of side walls constitutes the internal space of the frame, while the outer side of the side walls is configured to connect external components, so that the external components can be connected to the components in the internal space of the frame to achieve force conduction. The reinforcement structure can be a structure such as a reinforcing rib, which is used to enhance the structural strength of the frame. The external components include but are not limited to the front cabin upper side beam 40, the energy absorption box 30, the subframe 50, and the longitudinal beam 20. The frame can be connected to any component therein, so as to achieve force conduction between the external components.

[0062] In the above manner, the frame can realize the connection between multiple external components, and has a reinforcement structure to enhance the structural strength of the frame, which can better transmit the force, thereby providing a good side push support function.

[0063] In some embodiments, one of the accommodating spaces can be configured for connecting to a vehicle body longitudinal beam 20 , and at least one accommodating space having a reinforcement structure is arranged on an outer side of the vehicle body longitudinal beam 20 away from a center of the vehicle body.

[0064] In this way, the force from other external components connected to the frame can be transferred to the body rail 20, enabling the body rail 20 to provide effective side thrust support. Furthermore, the frame directly connects multiple different external components to form a frame structure, which can enhance the overall strength of the connection area between the body rail 20 and the joint device.

[0065] In some embodiments, the frame includes a first side wall 11, a second side wall 12, a third side wall 13, and a fourth side wall 14, which are connected in sequence. In addition to being connected to the third side wall 13, the fourth side wall 14 is also connected to the first side wall 11, thereby forming a rectangular frame. The first side wall 11, the second side wall 12, and the third side wall 13 are respectively connected to different external components. The reinforcement includes a first reinforcement 15 and a plurality of second reinforcements 16. The first reinforcement 15 is located between the second side wall 12 and the fourth side wall 14, with one end of the first reinforcement 15 connected to the first side wall 11 and the other end connected to the third side wall 13. The plurality of second reinforcements 16 are connected to the second side wall 12 at one end and to the fourth side wall 14 at the other end, and are cross-connected with the first reinforcement 15. In this embodiment, there are four second reinforcements 16; in other embodiments, the second reinforcements 16 include, but are not limited to, two, three, or more. The connector device 10 also includes a fixing plate 17, wherein, as shown in Figure 1, portions of at least two second reinforcement members 16, portions of the first reinforcement member 15, and portions of the second sidewall 12 enclose a first accommodation space. In practice, the portion of the first reinforcement member 15 located in the middle and between two adjacent second reinforcement members 16, the portions of two adjacent second reinforcement members 16 along the Z direction located between the first reinforcement member 15 and the second sidewall 12, and the portion of the second sidewall 12 between the two second reinforcement members 16 collectively enclose the first accommodation space. In some embodiments, there are four second reinforcement members 16 arranged along the Z direction, and portions of two adjacent second reinforcement members 16 located in the middle along the Z direction can be selected to enclose the first accommodation space. In this embodiment, the Z direction is the longitudinal length of the connector device 10. The first accommodation space is not a sealed space, but rather a space with an opening. The fixing plate 17 is disposed in the first accommodation space and is connected to the first reinforcement member 15, the second reinforcement member 16, and the second sidewall 12. In some embodiments, the fixing plate 17 is perpendicular to the first reinforcement 15 , the second reinforcement 16 , and the second side wall 12 .

[0066] The first reinforcement 15 and the second reinforcement 16 are cross-connected to each other, forming a crisscross structure in the internal space of the frame, thereby enhancing the structural strength of the connector device 10. At the same time, multiple areas surrounded by side walls, the first reinforcement 15, and the second reinforcement 16 are constructed in the internal space of the frame. These areas can be used to receive and install external components, or reinforcing structures can be added in the areas to improve the overall structural strength of the connector device 10.

[0067] The first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 are strip-shaped or plate-shaped structures that form the frame. Methods for connecting the first side wall 11, the second side wall 12, and the third side wall 13 to external components include, but are not limited to, welding, bolting, rivet connection, and snap-fit ​​connection. The first reinforcement 15 is also a strip-shaped or plate-shaped structure, but is located inside the frame to provide support and separation. The second reinforcement 16 is also a strip-shaped or plate-shaped structure, located inside the frame to provide support and separation. The difference between the second reinforcement 16 and the first reinforcement 15 is that they are located in different directions. The fixing plate 17 is a plate-shaped structure used to connect the longitudinal beam 20. In some embodiments, the frame, the first reinforcement 15, and the second reinforcement 16 are integrally formed, or the frame, the first reinforcement 15, the second reinforcement 16, and the fixing plate 17 are integrally formed and made of metal. Metals include, but are not limited to, aluminum alloys, steel, and steel alloys.

[0068] The first reinforcement 15 divides the frame of the joint device 10 into two parts, leaving a portion of the frame on one side of the fixing plate 17. The fixing plate 17 is used to connect to the longitudinal beam 20, leaving a portion of the frame to the side of the longitudinal beam 20. In the event of a side collision with the longitudinal beam 20, the force is transmitted to the longitudinal beam 20 through the frame, providing effective side thrust support. Furthermore, the frame directly connects to multiple external components to form a framework structure, enhancing the overall strength of the area connecting the longitudinal beam 20 to the joint device.

[0069] In some embodiments, a first fixing hole 111 is provided on the first side wall 11, a second fixing hole 121 is provided on the second side wall 12, a third fixing hole 131 is provided on the third side wall 13, and a fourth fixing hole is provided on the fourth side wall 14. The second side wall 12 and the fourth side wall 14 can be used to fix the same external component.

[0070] The first fixing hole 111, the second fixing hole 121, the third fixing hole 131, and the fourth fixing hole are configured as holes for securing the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 to an external component via a fixing member. Any two of the first fixing holes 111, the second fixing hole 121, the third fixing hole 131, and the fourth fixing hole can be the same or different. The number of first fixing holes 111 can be one, two, or more, depending on actual needs. Similarly, the number of second fixing holes 121, the third fixing hole 131, and the fourth fixing hole can be one, two, or more. Furthermore, while the second side wall 12 and the fourth side wall 14 can be used to secure 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 match different styles of fixing members, allowing for a variety of fixing methods for external components, thereby enhancing the securing effect.

[0071] The second side wall 12 and the fourth side wall 14 are fixed with the same external component at the same time, which can enhance the fixing strength of the external component and thus enhance the overall strength.

[0072] 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 .

[0073] The metal threaded sleeve is a metal tubular structure with threads both inside and outside. The external threads of the metal threaded sleeve are threadedly connected to the internal threads of the first fixing hole 111 and the internal threads of the third fixing hole 131. The internal threads of the metal threaded sleeve are used to threadably connect to an external component or a fixing member, thereby achieving a fixed connection between the external component or fixing member and the joint device. The metal threaded sleeve includes but is 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 side wall 11 and the third side wall 13, thereby improving the structural strength and connection strength of the first fixing hole 111 and the third fixing hole 131, and preventing the first fixing hole 111 and the third fixing hole 131 from being damaged during a collision.

[0074] 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.

[0075] In some embodiments, as shown in Figures 1-2, portions of at least two second reinforcement members 16, portions of the first reinforcement member 15, and portions 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 reinforcement structure 181 is disposed in the second accommodating space 18. The first reinforcement structure 181 can be fixedly connected to the sidewall of the second accommodating space 18. Specifically, the first reinforcement structure can connect the second reinforcement member 16, the first reinforcement member 15, and the fourth sidewall 14.

[0076] The portion of the first reinforcement member 15 between two adjacent second reinforcement members 16 located in the middle, the portion of the two adjacent second reinforcement members 16 located in the middle between the first reinforcement member 15 and the fourth side wall 14, and the portion of the fourth side wall 14 between two adjacent second reinforcement members 16 located in the middle, define a second accommodating space 18. In this embodiment, the first and second accommodating spaces 18 are defined by the same two second reinforcement members 16, but different portions of these two second reinforcement members 16 define the first and second accommodating spaces 18, respectively. The portions of the first reinforcement member 15 defining the first and second accommodating spaces 18 are identical. Therefore, the first and second accommodating spaces 18 are adjacent. The second accommodating space 18 is also not a sealed space, but rather a space with an opening. The first reinforcement structure 181 can be formed by intersecting multiple strip-like or plate-like structures, connecting the four corners of the second accommodating space 18, the fourth side wall 14, and the first reinforcement member 15. Alternatively, the first reinforcement structure 181 can also be connected only to the four corners of the second accommodating space 18; or alternatively, the first reinforcement structure 181 can also be connected to the two second reinforcement members 16. When the first reinforcement structure 181 is connected to the fourth side wall 14, the first reinforcement member 15 or the second reinforcement member 16, it is best to divide the fourth side wall 14, the first reinforcement member 15 or the second reinforcement member 16 that enclose the second accommodating space 18 into equal parts, so that the fourth side wall 14, the first reinforcement member 15 or the second reinforcement member 16 are evenly stressed. The intersection of the multiple strip structures or plate structures in the first reinforcement structure 181 is preferably the center position of the second accommodating space 18. In addition, the first reinforcement structure 181 includes but is not limited to this structure, and can also be a matrix structure cross-connected in two directions, a honeycomb structure, a structure with multiple triangles or trapezoids and the like arranged in an interlaced manner.

[0077] 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, so that when the joint device 10 is subjected to an impact force along the side of the longitudinal beam 20, it can withstand and absorb a large impact force and easily transmit the impact force to other components.

[0078] In some embodiments, the volume of the second accommodating space 18 is greater than the volume of the first accommodating space.

[0079] The second accommodating space 18 shares a portion of the first reinforcement 15 with the first accommodating space. Therefore, its volume is determined by the length of the second reinforcement 16 that encloses the first and second accommodating spaces 18. The volume of the second accommodating space 18 is greater than that of the first accommodating space. Specifically, the length of the portion of the second reinforcement 16 that encloses the second accommodating space 18 is greater than the length of the portion of the second reinforcement 16 that encloses the first accommodating space. The length of the second reinforcement 16 is parallel to the lateral direction of the longitudinal beam 20. The first accommodating space is used to accommodate the fixing plate 17 that connects the longitudinal beam 20. Therefore, the second accommodating space 18 is provided to increase the lateral collision distance of the longitudinal beam 20, specifically, the collision distance of the longitudinal beam 20 in the Y direction. This allows the longitudinal beam 20 to collide with the joint device 10, particularly the second accommodating space 18 portion of the joint device 10, earlier in the event of a lateral collision. This allows force to be transferred to the longitudinal beam 20, allowing the longitudinal beam 20 to participate in the collision earlier. In other embodiments, an extension with the same structure may also be provided on the other side of the first accommodating space. However, in general, the longitudinal beam 20 is arranged on one lateral side of the vehicle body. Therefore, in order to receive the collision outside the vehicle body, such a structure may be provided on the side of the longitudinal beam 20 away from the center of the vehicle body.

[0080] This arrangement enables the joint device 10 to be exposed to the impact in the lateral direction of the longitudinal beam 20 earlier, thereby transmitting and distributing the impact force, and enhancing the side thrust support function of the longitudinal beam end area.

[0081] In some embodiments, the connector device 10 includes at least four second reinforcement members 16, which are arranged sequentially. From the first sidewall 11 toward the third sidewall 13 (i.e., the direction opposite to the Z-direction), the first and second second reinforcement members 16, along with the second sidewall 12 and / or the third sidewall 13, form a third accommodating space 19. A second reinforcement structure 191 is disposed in the third accommodating space 19. From the third sidewall 13 toward the first sidewall 11 (i.e., the Z-direction), the first and second second reinforcement members 16, along with the second sidewall 12 and / or the third sidewall 13, also form a third accommodating space 19. A second reinforcement structure 191 is disposed in the third accommodating space 19. There are multiple third accommodating spaces 19, located on opposite sides of the first and second accommodating spaces 18.

[0082] The first accommodating space and the second accommodating space 18 are arranged along the extension direction of the second reinforcement 16, that is, the first accommodating space and the second accommodating space 18 are arranged along the Y direction. The Y direction is the horizontal length direction of the joint device 10. The third accommodating space 19 is located in the first accommodating space and the second accommodating space 18 and is arranged along the Z direction and / or the opposite direction of the Z direction. The setting of the third accommodating space 19 separates the first fixing hole 111 and the third fixing hole 131 from the first accommodating space and the second accommodating space 18. Therefore, when the joint 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 reinforcement structure 191 in the third accommodating space 19, and then transferred to the longitudinal beam 20, thereby enhancing the overall strength of the joint device 10. The second reinforcement structure 191 can be formed by the intersection of two strip structures or plate structures, respectively connecting the four corners of the third accommodating space 19, and the intersection is located at the center of the third accommodating space 19. The second reinforcement structure 191 can also be similar to the first reinforcement structure 181, formed by a plurality of cross-shaped strips or plate-like structures, or a matrix structure, a honeycomb structure, or a structure with multiple triangles or trapezoids arranged in a staggered manner in two directions. The first reinforcement structure 181 and the second reinforcement structure 191 can also be reinforcement ribs. In some embodiments, the first reinforcement structure 181 and the second reinforcement structure 191 are also integrally formed with the frame, the first reinforcement member 15, and the second reinforcement member 16. In addition, the four corners of the second accommodating space 18 and the third accommodating space 19 can also be provided with chamfered structures.

[0083] This design approach enables the frame to have multiple reinforcement structures, thereby enhancing the overall strength of the connector device 10 .

[0084] In some embodiments, the first side wall 11 , the third side wall 13 , and the second reinforcement 16 are arranged in parallel, and the second side wall 12 , the fourth side wall 14 , and the first reinforcement 15 are arranged in parallel.

[0085] In some embodiments, the first side wall 11 , the third side wall 13 , and the second reinforcement 16 are perpendicular to the second side wall 12 , the fourth side wall 14 , and the first reinforcement 15 .

[0086] This arrangement can make the shape of the connector device 10 more regular, and each accommodating space is a rectangular space, which is better for arranging reinforcement structures or accommodating external components.

[0087] Alternatively, the first side wall 11 , the third side wall 13 and the second reinforcement 16 are not perpendicular to the second side wall 12 , the fourth side wall 14 and the first reinforcement 15 but form an acute angle or an obtuse angle.

[0088] In some embodiments, as shown in FIG1 , in the X-direction, i.e., the depth direction of the connector device 10, the depth of the first accommodating space enclosed by the first reinforcement member 15 and the fixing plate 17 is less than the length of the second side wall 12 and the fourth side wall 14 in this depth direction. The first reinforcement member 15, the second reinforcement member 16, the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 have the same length in the X-direction, i.e., they have the same length in this depth direction, and the first reinforcement member 15, the second reinforcement member 16, the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 are located in the same plane along one side of the depth direction. The fixing plate 17 is connected to the side of the first reinforcement member 15 that is away from this plane.

[0089] The X direction in Figures 1 and 2 is the depth direction of the connector device 10, the Y direction is the lateral length of the connector device 10, and the Z direction is the longitudinal length of the connector device 10. The depth direction of the first reinforcement 15, the second reinforcement 16, the first side wall 11, the second side wall 12, the third side wall 13, and the fourth side wall 14 is the X direction. Assuming that the surface where the plane is located is the front of the frame and the surface opposite to the plane is the back of the frame, the longitudinal beam 20 is inserted from the front of the frame, that is, inserted into the first accommodating space along the opposite direction of the X direction and connected to the fixing plate 17. The energy absorption box 30 is connected to the connector device 10 on the back of the frame, that is, connected to the connector device 10 along the X direction, and connected to the first reinforcement 15 or the second reinforcement 16 or the fixing plate 17. The fixing plate 17 is arranged on the side of the first accommodating space facing the back of the frame. The first reinforcement 15 and the second reinforcement 16 are shorter in depth, that is, they occupy less space in the X direction, so a larger energy absorption box 30 can be inserted into the frame without being blocked by the first reinforcement 15 or the second reinforcement 16 .

[0090] This arrangement allows the end portion of the longitudinal beam 20 connected to the fixing plate 17 to be located in the first accommodating space, and the shorter length of the first reinforcement 15 in the X direction allows the other side of the fixing plate 17 to contact the external component, and part of the external component is located between the second side wall 12 and the fourth side wall 14, making it easier to connect to the second side wall 12 and the fourth side wall 14.

[0091] In some embodiments, alternatively, the lengths of the first reinforcement 15 and the second reinforcement 16 in the X direction are the same as the lengths of the second side wall 12 and the fourth side wall 14 in the X direction, and the energy absorption box 30 can be connected to the first reinforcement 15, the second reinforcement 16, the second side wall 12, and the fourth side wall 14. This allows the energy absorption 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 absorption box 30 can absorb energy earlier in the Y direction, thereby improving the lateral support capability.

[0092] In some embodiments, a welding portion 171 is provided on a surface of the fixing plate 17 facing the plane.

[0093] The welding portion 171 includes, but is not limited to, a strip-shaped raised structure and a dot-shaped raised structure. Multiple welding portions 171 may be provided, dispersedly arranged. Multiple groups of welding portions 171 may be provided. In some embodiments, the other side surface of the fixing plate 17 may also be provided with a welding portion 171 for welding to the crash box 30.

[0094] The provision of the welding portion 171 allows the fixing plate 17 to be better welded to the longitudinal beam 20 , thereby enhancing the connection strength between the joint device 10 and the longitudinal beam 20 .

[0095] In some embodiments, the connector device 10 further includes a bracket 101, which is connected to the first reinforcement member 15 and / or the second reinforcement member 16. The bracket 101 is a raised structure and may be provided with connection holes for connecting to a fan or other external components. Alternatively, in some embodiments, the bracket 101 may also serve as an auxiliary support.

[0096] The provision of the bracket 101 can enhance the strength of the first reinforcement member 15 and / or the second reinforcement member 16 , and can also connect other external components.

[0097] As shown in Figures 3 and 4, Figure 3 is a schematic diagram of the three-dimensional structure of a vehicle body according to some embodiments, and Figure 4 is a left view of the vehicle body according to some embodiments. The vehicle body includes a longitudinal beam 20, an energy absorption box 30, a subframe 50, a front cabin upper side beam 40, and a joint device 10. The joint device 10 is the joint device 10 in any of the above-mentioned embodiments. The subframe 50 and the front cabin upper side beam 40 are respectively connected to one of the side walls, and the longitudinal beam 20 and the energy absorption box 30 are respectively located on opposite sides of the joint device 10 and connected to opposite sides of the joint device 10.

[0098] In the above manner, the joint device 10 simultaneously connects the longitudinal beam 20, the energy absorption box 30, the subframe 50 and the front cabin upper side beam 40, so that the longitudinal beam 20, the subframe 50 and the front cabin upper side beam 40 form an integral frame structure with strong structural strength, which can cope with and absorb impact forces in all directions; when any point in the overall frame structure is subjected to force, the force can be transmitted to other components.

[0099] In some embodiments, a fixing plate 17 is provided in a receiving space, and the longitudinal beam 20 is connected to the fixing plate 17 in the receiving space. At least one receiving space with a reinforcement structure is arranged on the outer side of the longitudinal beam away from the center of the vehicle body.

[0100] This approach makes the connection between the longitudinal beam 20 and the joint device 10 more stable, and the joint device 10 can better transfer the force to the longitudinal beam 20 after being subjected to force.

[0101] In some embodiments, the crash box 30 is connected to the fixing plate 17 .

[0102] In this way, the energy absorption box 30 and the longitudinal beam 20 can be connected through the fixing plate 17, and the connection between the energy absorption box 30 and the longitudinal beam 20 is more stable.

[0103] In some embodiments, the longitudinal beam 20 and the crash box 30 are both perpendicular to the fixing plate 17. The area of ​​the surface of the longitudinal beam 20 connected to the fixing plate 17 is smaller than the area of ​​the surface of the crash box 30 connected to the fixing plate 17.

[0104] The longitudinal beam 20 and the crash box 30 are both perpendicular to the fixing plate 17, and are located on opposite sides of the fixing plate 17. Therefore, the surface where the longitudinal beam 20 connects to the fixing plate 17 and the surface where the crash box 30 connects to the fixing plate 17 are opposite sides of the fixing plate 17. The larger the surface where the crash box 30 connects to the fixing plate 17, the larger the crash box 30. In other words, in the YZ plane, the area of ​​the crash box 30 is larger than that 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 crash box 30 still partially extends. Because the crash box 30 still partially extends along the side of the longitudinal beam 20, a larger crash box 30 can be used, and both sides can be connected to the joint device 10, and the crash box 30 is not limited to a crash box 30 of the same size as the cross-section of the longitudinal beam 20.

[0105] This configuration allows the vehicle body to use a larger energy absorption box 30, thereby achieving a better force dispersion effect.

[0106] In some embodiments, the crash box 30 extends beyond the longitudinal beam 20 in a direction away from the vehicle body.

[0107] Similarly, this arrangement is also intended to allow the vehicle body to use a larger energy absorption box 30, thereby achieving a better force dispersion effect.

[0108] In the above embodiment, each accommodating space can be regarded as a region, and the connector device 10 is surrounded by four side walls to form an internal space of the connector device 10, and is divided into multiple regions by the first reinforcement member 15 and the second reinforcement member 16. The first accommodating space is the first region.

[0109] In some specific application scenarios, in order to address the problem that the overall strength of the relevant parts of the existing vehicle body longitudinal beam 20 is insufficient and cannot form a good side thrust support function, the joint device 10 of the present application includes a frame, a first reinforcement 15, four second reinforcements 16 and a fixing plate 17. The frame includes a first side wall 11, a second side wall 12, a third side wall 13 and a fourth side wall 14 connected in sequence. In addition to being connected to the third side wall 13, the fourth side wall 14 is also connected to the first side wall 11, thereby forming a rectangular frame. The first side wall 11, the second side wall 12 and the third side wall 13 are respectively connected to different external components. The first reinforcement 15 is connected to the first side wall 11 at one end and to the third side wall 13 at the other end, and is arranged between the second side wall 12 and the fourth side wall 14. The four second reinforcements 16 are connected to the second side wall 12 at one end and to the fourth side wall 14 at the other end, and are cross-connected with the first reinforcement 15. The four second reinforcements 16 are parallel to each other. Portions of the two middle second reinforcements 16, portions of the first reinforcement 15, and portions of the second sidewall 12 enclose a first accommodation space. In practice, the portion of the first reinforcement 15 between the two middle, adjacent second reinforcements 16, the portion of the two middle, adjacent second reinforcements 16 between the first reinforcement and the second sidewall 12, and the portion of the second sidewall 12 between the two middle, adjacent second reinforcements 16 enclose the first accommodation space. The first accommodation space is not a sealed space, but rather a space with an opening. A fixing plate 17 is disposed in the first accommodation space and is connected to the first reinforcement 15, the second reinforcement 16, and the second sidewall 12. The fixing plate 17 is perpendicular to the first reinforcement 15, the second reinforcement 16, and the second sidewall 12. In some embodiments, portions of the two middle second reinforcements 16, portions of the first reinforcement 15, and portions of the fourth sidewall 14 enclose a second accommodation space 18. The second accommodation space 18 is adjacent to the first accommodation space. A first reinforcement structure 181 is disposed in the second accommodating space 18 . The first reinforcement structure 181 connects the second reinforcement member 16 , the first reinforcement member 15 and the fourth side wall 14 .

[0110] The provision of the first reinforcement 15 divides the frame of the joint device 10 into two parts, leaving a portion of the frame on one side of the fixing plate 17. The fixing plate 17 is used to connect to the longitudinal beam 20, thus leaving a portion of the frame on the side of the longitudinal beam 20 away from the center of the vehicle body. In the event of a side collision on the longitudinal beam 20, the force is transmitted to the longitudinal beam 20 through the frame, providing effective side thrust support. Furthermore, the direct connection of the frame to multiple external components enhances the overall strength of the portion of the vehicle body related to the longitudinal beam 20.

[0111] Although in the above embodiment, the first reinforcement member 15 is connected to the first and third side walls, and the second reinforcement member 16 is connected to the second and fourth side walls, alternatively, the first reinforcement member 15 may be connected to only one of the first and third side walls, with the other end of the first reinforcement member 15 connected to the second reinforcement member 16; and / or the second reinforcement member 16 may be connected to only one of the second and fourth side walls, with the other end of the second reinforcement member 16 connected to the first reinforcement member 15. In this way, areas of different sizes and positions can be constructed within the internal space of the connector device 10 to accommodate various requirements.

[0112] Although in the above embodiment, the frame includes a first side wall, a second side wall, a third side wall and a fourth side wall, the present application is not limited to this. Alternatively, the frame may also include three, five, six or other numbers of side walls. In the frame space surrounded by the side walls, the reinforcements can be connected to the corresponding side walls according to design requirements, and different connection structures can be constructed between the reinforcements as needed.

[0113] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
