Description

Technical Field

[0001] This utility model relates to the field of vehicle bracket structure technology, specifically to a frame reinforcement connection structure and bracket. Background Technology

[0002] With technological advancements, new energy heavy-duty trucks have been developed and put into use. The battery pack structure of these trucks is mounted on a bracket connected to the vehicle's main beam. This bracket structure serves to install, stabilize, and protect the battery pack. A conventional bracket consists of a frame and a base. To facilitate processing and installation, the frame is composed of multiple horizontally arranged and fixedly connected frame bodies. Each frame body is welded and fixed by multiple support frames. After these frame bodies are sequentially welded and fixed to form the frame, the frame is then fixedly installed on the base. Finally, the base is fixed to the heavy-duty truck's main beam. The top surface of the frame can then be used to install and fix the existing battery pack.

[0003] Although existing brackets can be used to install and fix the battery pack, especially since the brackets can provide stable support for the battery pack in the vertical direction, the force exerted by the battery pack on the bracket during actual driving, especially during turning, is not only along the vertical direction but also has a lateral component force. Since the frame body is only fixedly connected between adjacent frame bodies, the lateral load-bearing capacity of the frame is not effective. In order to improve the stability of supporting and fixing the battery pack, it is necessary to improve the existing bracket structure. Utility Model Content

[0004] The present invention aims to provide a frame reinforcement connection structure and bracket to solve the problem that the brackets in the prior art have weak lateral connection stability and cannot provide stable support for the battery pack.

[0005] To solve the above problems, the present invention adopts the following technical solution: a frame reinforcement connection structure, including at least two frame bodies arranged horizontally side by side and fixedly connected to each other, with a socket portion provided on the front and / or rear side of the frame body; and further including a horizontal fixing member fixedly connected to all frame bodies at the same time, with a plug-in portion on the horizontal fixing member having the same number of socket portions as all frame bodies and corresponding to each other.

[0006] The principles and beneficial effects of this application are as follows: In this application, all frame bodies are arranged side by side along the left and right sides and are fixedly connected to each other in pairs to form a frame structure in the prior art. All frame bodies are connected as a whole and can provide stable support for the battery pack in the prior art, especially in the vertical direction. At the same time, in this application, horizontal fasteners are fixedly connected to the outside of the frame bodies, and the horizontal fasteners are also fixedly connected to the side walls of all frame bodies. The use of horizontal fasteners can improve the structural strength of the connection of all frame bodies as a whole, thereby improving the overall structural strength of the frame, so as to provide more stable support for the battery pack.

[0007] Specifically, in this application, a socket is provided on the front and / or rear side of each frame body, and a number of plug-in parts are provided on the lateral fasteners, which are equal to and correspond one-to-one with the number of sockets on all frames. When the lateral fasteners are fixedly connected to all frame bodies, the plug-in parts are inserted into the sockets, which enhances the connection stability between the lateral fasteners and all frame bodies. In particular, the cooperation between the lateral fasteners and the plug-in parts makes the connection of the frame bodies in the lateral direction more stable. During subsequent use, it can withstand the lateral force exerted on the frame by the battery pack, thereby making the battery pack more stably supported and fixed.

[0008] Preferably, as an improvement, the socket is located at the top of the front and / or rear side of the frame body, and the top of the frame body is provided with a vertical fixing member that is vertically fixed to the socket.

[0009] In this design, the socket is located on the side of the frame body near the top, so that the horizontal fastener, after being connected to the frame body, is also located on the side of the frame body at the top. This allows the horizontal fastener to strengthen and fix the top position of all connected frame bodies. However, the bottom reinforcement structure of the frame body is relatively weak, which is consistent with the usage situation after multiple frame bodies are connected. This is because the bottom of all frame bodies is connected to a structurally stable base, and the force of the battery pack has a greater impact on the top of the frame body. Therefore, in this design, the horizontal fastener is connected near the top of the frame body, which can provide better lateral reinforcement and stability to the frame body.

[0010] In addition, in this embodiment, a vertical fixing member is provided at the top of the frame body to fix the plug-in part vertically. The plug-in part is fixed from the top of the frame body downward by the vertical fixing member. This not only makes the operation convenient, but also prevents the plug-in part from easily coming out of the socket after the vertical fixing member fixes the plug-in part. This makes the connection between the horizontal fixing member and the frame body more stable and further improves the stability of all frame bodies after they are connected as one, so as to provide a more stable fixing effect for the battery pack.

[0011] Preferably, as an improvement, each frame body is provided with several sockets, which are spaced apart along the transverse arrangement direction of all frame bodies, and frame support ribs are provided between adjacent sockets.

[0012] In this design, multiple sockets are provided on each frame body, and correspondingly, multiple insertion parts are provided on the transverse fasteners to cooperate with the sockets. The multiple sockets are arranged along the transverse direction of all frame bodies, so that the multiple sockets are arranged along the length direction of the transverse fasteners. This facilitates the installation of insertion parts on the transverse fasteners and avoids the transverse fasteners being too wide. In addition, frame support plates are provided between adjacent sockets. The frame support plates are used to reinforce the frame bodies with sockets, effectively ensuring the structural strength of the frame bodies and enabling the frame bodies to stably support and fix the battery pack.

[0013] Preferably, as an improvement, the socket includes a slot that extends through the frame body and is arranged in a direction perpendicular to the arrangement of all frame bodies.

[0014] In this design, the sockets are arranged horizontally along the direction perpendicular to the arrangement of all frame bodies, which facilitates the smooth insertion of all plug-in parts into the sockets and makes the horizontal fasteners and plug-in parts easy to install; at the same time, by setting the sockets near the top of the frame body, the weight of the entire frame body can be effectively reduced.

[0015] Preferably, as an improvement, the lateral fixing member includes a lateral fixing plate, and the plug-in part includes a plug-in seat fixedly connected to the lateral fixing plate.

[0016] In this solution, the horizontal fastener is a plate-shaped horizontal fastening plate, which can be easily fixed to the side of the frame body by welding; the plug-in part is a plug-in seat structure, which can be directly plugged into the socket during installation and fixing to accurately complete the installation operation.

[0017] Preferably, as an improvement, the connector is provided with weight-reducing grooves along all the arrangement directions of the frame body.

[0018] While ensuring the stability of all frame body connections by inserting the connector into the socket, this solution incorporates a weight-reducing groove on the connector to effectively reduce the overall weight of the structure. Furthermore, this weight-reducing groove is positioned along the entire frame body layout, giving the connector a U-shaped cross-section. This weight reduction effectively maintains the structural strength of the connector. Especially when the connector is inserted into the socket, the horizontal fixing plate is located at the top of the front and / or rear sides of the frame body. Therefore, the connector inserted into the socket provides auxiliary vertical support to the top of the front and / or rear sides of the frame body after the socket is installed, ensuring sufficient strength at the top of the frame body (particularly near the sides) to stably support and fix the battery pack.

[0019] Preferably, as an improvement, the weight-reducing groove is fixedly connected with a plug-in support plate, and the plug-in support plate is arranged along the direction of all the frame bodies.

[0020] In this solution, by setting up a plug-in support rib, the structural strength of the plug-in seat is further improved, so that after the plug-in seat is inserted into the socket, it can more stably assist in supporting the top of the frame body near the side.

[0021] Preferably, as an improvement, the insertion depth of the plug portion into the socket portion is greater than or equal to 80 mm.

[0022] In this design, the insertion depth of the plug-in part into the socket part is greater than or equal to 80mm, which facilitates the plug-in part to form a stable fixed connection with the frame body. This effectively ensures that after the horizontal fasteners are connected to all frame bodies, the plug-in part can form a stable connection with the corresponding frame body.

[0023] Preferably, as an improvement, the vertical fixing member includes a vertical fixing screw, the top of the frame body has a through hole, and the plug-in seat has a threaded hole that is vertically opposite to the through hole, the threaded hole being vertically inserted into or through the support plate rib.

[0024] In this design, the vertical fixing screw passes through the through hole and is threaded into the threaded hole, thus fixing the vertical fixing screw to the connector in a vertical direction. After fixing, the connector cannot move laterally and exit the connector slot, making the connector and the horizontal fixing plate more securely connected to all the frame bodies. In addition, the threaded hole is inserted vertically into or through the connector support plate rib, which not only facilitates the installation of the threaded hole but also provides sufficient space. Furthermore, when the vertical fixing screw is connected to the connector, it is also fixed to the connector support plate rib, further improving the overall stability of the connector and the frame body.

[0025] A bracket, comprising the aforementioned frame reinforcement connection structure.

[0026] In this solution, the bracket is equipped with a frame reinforcement connection structure, which allows the frame bodies to be connected side by side in the horizontal direction and further reinforced and fixed by the horizontal fasteners. This makes the stability better after all the frame bodies are connected as one. It can not only withstand the vertical gravity of the battery pack, but also stably install and fix the battery pack in the horizontal direction, thus improving the stability of the battery pack installation and fixation.

[0035] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: frame body 1, socket 101, mounting groove 102, through hole 103, frame support plate 2, horizontal fixing plate 3, plug-in seat 4, weight reduction groove 401, threaded hole 402, and plug-in support plate 5.

[0036] Example 1 This embodiment is as shown in the attached figure. Figure 1 As shown: A frame reinforcement connection structure includes at least two frame bodies 1 arranged horizontally side by side and fixedly connected to each other. The frame bodies 1 are made of aluminum alloy material and are integrally formed by extrusion. The adjacent frame bodies 1 are fixed to each other by friction stir welding. Figure 1The diagram shows ten frame bodies 1 fixed side by side. After all the frame bodies 1 are fixed laterally, they form a top support plane. The battery pack in the prior art can be fixed to the top support plane by bolts or other means. Therefore, in actual application, the lateral arrangement of all the frame bodies 1 is along the Y direction of the vehicle so that all the frame bodies 1 are fixed to each other before being installed and fixed on the vehicle.

[0037] In this embodiment, a socket is provided on the front and / or rear side of the frame body 1, and a transverse fastener is fixedly connected to the outer side of the frame body 1. The transverse fastener is provided with a plug-in part that is equal in number to and corresponds one-to-one with the sockets in all the frame bodies 1. Figure 1 The following example illustrates the use of a frame body 1 with sockets installed on both the front and rear sides.

[0038] Combination Figure 1 , Figure 2 and Figure 3 Each frame body 1 is provided with several socket portions, which are spaced apart along the transverse arrangement direction of all frame bodies 1. In this embodiment, the socket portions include socket slots 101 formed by integral extrusion molding on the front and rear top positions of the frame body 1. The socket slots 101 penetrate the frame body 1, so that the socket slots 101 on the front and rear sides of the frame body 1 are interconnected, and the socket slots 101 are arranged perpendicular to the arrangement direction of all frame bodies 1. Figure 3 The frame body 1 shown in the figure is provided with two support slots 101. In order to ensure the structural strength after the support slots 101 are provided on the top of the frame body 1, the adjacent support slots 101 are formed by integral extrusion molding of the frame support plate 2.

[0039] Combination Figure 1 and Figure 4 The horizontal fasteners include horizontally arranged horizontal fixing plates 3. The length of the horizontal fixing plates 3 is equal to the length of all the frame bodies 1 after being fixed and connected side by side. To improve the overall structural integrity and aesthetic appearance, combined with... Figure 3 In this embodiment, mounting grooves 102 that mate with the transverse fixing plate 3 are provided at the top front and rear sides of the frame body 1. The transverse fixing plate 3 is fixed to the front and rear sides of the frame body 1 by friction stir welding. The top of the transverse fixing plate 3 is flush with the top of the frame body 1, and the outer side of the transverse fixing plate 3 is flush with the front or rear side of the frame body 1. Figure 5In this embodiment, the insertion part includes an insertion seat 4 integrally formed on the side of the transverse fixing plate 3 facing the frame body 1. The insertion seat 4 is inserted into the socket 101, so that the transverse fixing plate 3 is more firmly connected to the frame body 1 through the insertion of the insertion seat 4 and the socket 101, thereby improving the stability of all frame bodies 1 after being fixedly connected to each other. In addition, in order to ensure the stability of the connection after the insertion seat 4 is inserted into the socket 101, the insertion depth of the insertion seat 4 into the socket 101 is greater than or equal to 80mm, preferably 85 or 90mm. In order to reduce the weight of the insertion seat 4 and ensure the structural strength of the insertion seat 4, in this embodiment, a weight-reducing groove 401 is provided on the insertion seat 4 by integral extrusion molding or other means along the length direction of the transverse fixing plate 3, and a vertically arranged insertion support plate rib 5 is fixedly connected in the weight-reducing groove 401 by integral extrusion molding or other means. The insertion support plate rib 5 is arranged along the length direction of the transverse fixing plate 3.

[0040] In this embodiment, all frame bodies 1 are fixed together by friction stir welding, forming a frame that supports and fixes the battery pack. Simultaneously, horizontal fixing plates 3 are welded and fixed to the top front and rear sides of the frame body. Since the horizontal fixing plates 3 are simultaneously fixed to all frame bodies 1, the overall stability of the integrated frame bodies 1 is enhanced. The insertion seats 4 on the horizontal fixing plates 3 engage with the slots 101 on the frame bodies 1, further improving the stability of the horizontal fixing plates 3 after fixing all frame bodies 1. When the battery pack is fixed to the top of the frame, all frame bodies not only provide stable support for the battery pack in the vertical direction but also withstand the lateral force exerted by the battery pack on the frame, thus ensuring a more stable and secure fixation of the battery pack.

[0041] A bracket includes the aforementioned frame reinforcement connection structure. All the frame bodies 1 in the bracket are stably connected and can stably withstand the vertical and lateral forces of the battery pack, thereby providing stable support and fixation for the battery pack.

[0042] Example 2 The difference between Example 2 and Example 1 is as follows: Figure 6 As shown, in this embodiment, a vertical fixing member is provided at the top of the frame body 1, which is vertically fixed to the plug-in seat 4. Specifically, in conjunction with... Figure 7 and Figure 8 The vertical fixing component includes a vertical fixing screw. The top of the frame body 1 has a vertical through hole 103. The plug-in seat 4 has a threaded hole 402 that is vertically opposite to the through hole 103. In order to facilitate and stably set the threaded hole 402, the threaded hole 402 is vertically inserted into or vertically penetrates the support plate rib 5. In this embodiment, the threaded hole 402 is vertically penetrated into the support plate rib 5.

[0043] In this embodiment, after the horizontal fixing plate 3 is welded and fixed to the front or rear side of the frame body 1, the plug-in seat 4 is inserted into the socket 101. Then, the vertical fixing screw is passed through the through hole 103 and locked with the threaded hole 402. The vertical fixing component limits the plug-in seat 4 in the horizontal direction. The vertical fixing screw can prevent the plug-in seat 4 from loosening outside the socket 101, further improving the connection stability between the plug-in seat 4 and the socket 101, thereby improving the connection stability between the horizontal fixing plate 3 and the frame body 1, so that the horizontal fixing plate 3 can more firmly connect all the frame bodies 1 into one, and play a more stable fixing role for the battery pack.
