Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to an aluminum alloy frame of a new energy automobile instrument panel with a stable structure. Background Art

[0002] The car dashboard frame is the supporting structure of the car instrument panel, which is connected to the body frame. It is usually made of aluminum alloy materials through stamping, welding and other processes. It has the characteristics of lightweight, corrosion resistance and strong rigidity. Therefore, the car dashboard frame can also play a certain protective role for the people in the cockpit and improve the overall safety of the vehicle.

[0003] The patent publication number CN218558973U discloses a cross beam of an automobile dashboard, including a cross beam skeleton body, a floor connection bracket is fixedly installed at the bottom of the middle section of the surface of the cross beam skeleton body, and a steering column connection assembly is provided on the surface of one side of the cross beam skeleton body. This technology not only reduces the overall weight of the device by more than 30%, but also can greatly improve the safety factor, and effectively improve the anti-shake ability of the steering wheel, and can effectively suppress the local resonance that will appear during the acceleration process, greatly improving the driving comfort. Secondly, while the overall structural stability is improved, the anti-deformation performance during assembly installation can also be further enhanced. There is no need to use a crushing method to dock with the connection part of the body structure, which greatly reduces the assembly cost and improves the quality of assembly assembly. At the same time, the box-shaped structure can effectively improve the torsional stiffness.

[0004] The prior art has the following defects: Since a large area of ​​batteries need to be laid on the bottom of new energy vehicles, this will cause the overall weight of new energy vehicles to be heavy. In order to increase the endurance of new energy vehicles, the car frame will be made of lighter aluminum alloy materials during design, and the corresponding parts of the internal body frame, such as the dashboard frame, will be further thinned. This will cause the impact resistance of the main structure of the dashboard frame to be weakened and the structural stability to be insufficient. When hit by a large vehicle, it is prone to huge deformation or fracture, and cannot provide adequate protection for the people in the car.

[0005] The main body of the dashboard skeleton is the main beam, and the outer side of the main beam is welded with steering column mounting bracket, instrument mounting bracket, airbag mounting bracket, storage box or glove box mounting bracket and other structural parts. Due to the high thermal conductivity and large thermal expansion coefficient of aluminum alloy materials, they are easily deformed under the influence of welding heat. Some structural parts are large in size and have a large contact area with the main beam, so large-area welding is required. This will cause the local deformation of the main beam to be aggravated and the structural stability of the main body will be affected. In order to save costs and improve efficiency, spot welding is mostly used in the welding process, which affects the overall strength and stability of the dashboard skeleton. Summary of the invention

[0006] In view of the problem that the instrument panel frame structure is weak in stability in the prior art, a new energy vehicle instrument panel aluminum alloy frame with a stable structure is proposed.

[0007] The present application provides a structurally stable aluminum alloy frame for a new energy vehicle instrument panel, the purpose of which is to enhance the structural stability of the instrument panel frame.

[0008] The technical solution of the present invention is: a structurally stable aluminum alloy frame of a new energy vehicle dashboard, comprising a main beam, a steering column bracket, a support fixing frame, an auxiliary mounting frame, and a side connection assembly arranged outside the main beam, wherein the main beam specifically comprises an outer tube and an inner tube plugged into the inner part of the outer tube; The cross section of the outer cylinder is circular, the cross section of the inner cylinder is hexagonal, and the six sides of the outer side of the inner cylinder are in contact with the inner wall of the outer cylinder.

[0009] Furthermore, six interlayer intervals are arranged between the outer tube and the inner tube, the interlayer intervals are filled with filling pads, adjacent filling pads are connected by connecting belts, and the six filling pads are connected in series through the connecting belts and are surrounded by the outer side of the inner tube.

[0010] Furthermore, the side connection assembly specifically includes fixed side plates arranged at both ends of the main beam, a connection sleeve arranged on the outside of the fixed side plates, and an inner support platform arranged on the inside of the fixed side plates; The fixed side plate is sleeved on the outside of the outer cylinder, and the inner support platform is inserted into the inner cylinder.

[0011] Furthermore, a fixing assembly is provided between the main beam and the steering column bracket, the support fixing frame, and the side connection assembly, and the fixing assembly specifically comprises a fixing screw hole opened on the surface of the outer cylinder and a fixing bolt inserted into the fixing screw hole; The fixing screw holes penetrate the outer tube, the inner tube, and the filling pad inwardly in sequence, and penetrate the steering column bracket, the support fixing frame, and the side connection assembly outwardly respectively. The fixing bolts are connected to the fixing screw holes through threads, and respectively fix the steering column bracket, the support fixing frame, and the side connection assembly to the outside of the outer tube.

[0012] Furthermore, a reinforcement component is provided on the outer side of the main beam, and the reinforcement component specifically includes a fastening screw hole opened on the outer side of the outer tube and a reinforcement bolt inserted into the fastening screw hole; The fastening screw hole penetrates the outer cylinder, the inner cylinder and the filling pad front and back, and the reinforcing bolt is connected to the fastening screw hole through a thread.

[0013] Furthermore, the fixing bolt and the reinforcing bolt are both provided with a locking assembly, which specifically includes an inner slot opened inside the fixing bolt and the reinforcing bolt, a side opening opened outside the fixing bolt and the reinforcing bolt, a locking bolt arranged inside the inner slot, a receiving slot opened outside the locking bolt, and a piercing rod arranged inside the receiving slot; The side opening is communicated with the inner slot, the side opening is designed to be inclined, the opening of one end of the side opening close to the inner slot is larger than the opening of the other end, and the puncture rod punctures into the filling pad.

[0014] Furthermore, the locking assembly further comprises a limiting sleeve arranged outside the fixing bolt and the reinforcing bolt, a ring groove provided outside the fixing bolt and the reinforcing bolt, and an elastic ring arranged inside the limiting sleeve; The limiting sleeve is wrapped around the outer side of the opening of the inner slot, the elastic ring sleeve is buckled in the ring groove, and the locking bolt is pressed against the surface of the limiting sleeve.

[0015] Furthermore, the interior of the filling pad is filled with interlaced fiber threads, and the fiber threads are wound into the threads on the outside of the fixing bolts and the reinforcing bolts.

[0016] Beneficial effects of the present invention: 1. By setting the main beam as double-layer, the circular cross-section of the outer tube has better radial stability, and the hexagonal shape of the inner tube can play a supporting and strengthening role in the inner layer. Especially when bearing asymmetric loads or torsional forces, the edges and sides of the hexagon can cooperate with the outer cylindrical tube to enhance the stability and bearing capacity of the overall structure. In this way, the stability of the skeleton is improved on the basis of increasing the gravity of the skeleton.

[0017] 2. By filling the filling pad between the outer tube and the inner tube, the filling pad can play a certain supporting role on the outer tube, and the force on the outer tube can be better transmitted to the inner tube, so that the structural stability of the outer tube and the inner tube is further improved.

[0018] 3. By setting reinforcing bolts, the reinforcing bolts connect the front and rear sides of the outer tube and the inner tube. When the front end of the main beam is subjected to force, the force can be transmitted to the rear of the main beam through the reinforcing bolts, so that the force is evenly dispersed throughout the main beam, further enhancing the stability of the structure. At the same time, the fiber threads in the filling pad are wound around the outside of the fixing bolts and the reinforcing bolts. When the main beam is broken or shattered due to severe collision, the fixing bolts and the reinforcing bolts will not splash toward the people in the car under the action of inertia, thereby improving safety.

[0019] 4. By setting a locking assembly, the puncture rod passes through the storage groove and into the filling pad, locking the fixing bolts and the reinforcement bolts with the filling pad. The puncture rod is entangled by the fiber threads in the filling pad and is difficult to move in a circular direction. This can prevent the fixing bolts and the reinforcement bolts from gradually loosening due to the vibration of the vehicle, resulting in a decrease in the connection stability of the components.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] Example 1, reference Figure 1-11 , which is the first embodiment of the present invention, provides a structurally stable aluminum alloy skeleton of a new energy vehicle dashboard, including a main beam 1, a steering column bracket 2, a support fixing frame 3, an auxiliary mounting frame 4, and a side connecting assembly 5 arranged outside the main beam 1, and the main beam 1 specifically includes an outer tube 11, and an inner tube 12 plugged into the inner part of the outer tube 11; Specifically, components such as the steering column bracket 2 and the supporting fixing frame 3 are relatively large, and their contact area with the main beam 1 is also relatively large, so they are fixed to the main beam 1 with bolts, and components such as the auxiliary mounting frame 4 are welded to the main beam 1. The cross-section of the outer tube 11 is circular, and the cross-section of the inner tube 12 is hexagonal. The six sides of the outer side of the inner tube 12 are in contact with the inner wall of the outer tube 11. The outer tube 11 and the inner tube 12 are made of aluminum alloy material, and the thickness of both is 2 mm (the thickness of ordinary skeletons is 4 mm).

[0024] By setting the main beam 1 as a double-layer, the circular cross-section of the outer tube 11 has better radial stability, and the hexagonal shape of the inner tube 12 can support and strengthen the inner layer. Especially when subjected to asymmetric loads or torsional forces, the hexagonal edges and sides can cooperate with the outer cylindrical tube to enhance the stability and bearing capacity of the overall structure. In this way, the stability of the skeleton is improved on the basis of increasing the gravity of the skeleton.

[0025] Specifically, six interlayer intervals are provided between the outer tube 11 and the inner tube 12 , and the interlayer intervals are filled with filling pads 13 . Connecting belts 14 are connected between adjacent filling pads 13 . The six filling pads 13 are connected in series through the connecting belts 14 and are surrounded by the outer side of the inner tube 12 .

[0026] By filling the filling pad 13 between the outer tube 11 and the inner tube 12, the filling pad 13 can play a certain supporting role on the outer tube 11, and can also better transfer the force exerted on the outer tube 11 to the inner tube 12, so that the structural stability of the outer tube 11 and the inner tube 12 is further improved.

[0027] The side connection assembly 5 specifically includes fixed side plates 51 disposed at both ends of the main beam 1, a connection sleeve 52 disposed on the outside of the fixed side plates 51, and an inner support platform 53 disposed on the inside of the fixed side plates 51; Specifically, the fixed side panel 51 is fixed to the inner side of the A-pillar of the automobile. The fixed side panel 51, the connecting sleeve 52 and the inner support platform 53 are integrally formed by milling equipment. The fixed side panel 51 is sleeved on the outer side of the outer tube 11, and the inner support platform 53 is inserted into the inner tube 12.

[0028] By setting the side connection assembly 5, the main beam 1 is fixed between the A-pillars of the automobile, and part of the force is transmitted to the A-pillars of the automobile when it is impacted. At the same time, the fixed side plate 51 is sleeved on the outside of the outer tube 11, and the inner support platform 53 is inserted into the inner tube 12. In this way, the contact area between the main beam 1 and the side connection assembly 5 is increased, and the force transmission is better realized. In addition, the inner support platform 53 can also play a certain supporting role on the inner tube 12, so that the structure of the main beam 1 is more stable.

[0029] A fixing assembly 6 is provided between the main beam 1 and the steering column bracket 2, the support fixing frame 3, and the side connecting assembly 5. The fixing assembly 6 specifically includes a fixing screw hole 61 opened on the surface of the outer tube 11 and a fixing bolt 62 inserted into the fixing screw hole 61; Specifically, the fixing screw hole 61 penetrates the outer tube 11, the inner tube 12, and the filling pad 13 inwardly in sequence, and penetrates the steering column bracket 2, the support fixing frame 3, and the side connection assembly 5 outwardly respectively. The fixing bolt 62 is connected to the fixing screw hole 61 through a thread, and fixes the steering column bracket 2, the support fixing frame 3 and the side connection assembly 5 to the outside of the outer tube 11 respectively. The length of the fixing bolt 62 is smaller than the radius of the outer tube 11. By using the fixing bolt 62 for fixing, the connection point can be made more stable.

[0030] A reinforcement component 7 is provided on the outer side of the main beam 1. The reinforcement component 7 specifically includes a fastening screw hole 71 provided on the outer side of the outer tube 11 and a reinforcement bolt 72 inserted into the fastening screw hole 71. The fastening screw hole 71 passes through the outer tube 11, the inner tube 12, and the filling pad 13 from front to back. The reinforcing bolt 72 is connected to the fastening screw hole 71 by a thread. The length of the reinforcing bolt 72 is greater than the diameter of the outer tube 11. The reinforcing bolt 72 adopts a horizontal design. The reinforcing bolt 72 is distributed in a linear array on the outside of the main beam 1; the inside of the filling pad 13 is filled with interlaced fiber threads, and the fiber threads are wound into the threads of the fixing bolt 62 and the outer side of the reinforcing bolt 72. By setting the reinforcing bolts 72, the reinforcing bolts 72 connect the front and rear sides of the outer tube 11 and the inner tube 12. In this way, when the front end of the main beam 1 is subjected to force, the force can be transmitted to the rear of the main beam 1 through the reinforcing bolts 72, so that the force is evenly dispersed in various parts of the main beam 1, further enhancing the stability of its structure. At the same time, the fiber threads in the filling pad 13 are wound around the outside of the fixing bolts 62 and the reinforcing bolts 72. In this way, when the main beam 1 is broken or shattered due to severe collision, the fixing bolts 62 and the reinforcing bolts 72 will not splash toward the people in the car under the action of inertia, thereby improving safety.

[0031] Example 2, reference Figure 1-14 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a locking assembly 8 is provided inside the fixing bolt 62 and the reinforcing bolt 72. The locking assembly 8 specifically includes an inner slot 81 opened inside the fixing bolt 62 and the reinforcing bolt 72, a side opening 82 opened outside the fixing bolt 62 and the reinforcing bolt 72, a locking bolt 83 arranged inside the inner slot 81, a receiving slot 84 opened outside the locking bolt 83, and a piercing rod 85 arranged inside the receiving slot 84; Specifically, the inner slot 81 axially passes through the heads of the fixing bolt 62 and the reinforcing bolt 72. The heads of the fixing bolt 62 and the reinforcing bolt 72 are both provided with hexagonal slots. The side opening 82 is connected to the inner slot 81. The side opening 82 adopts an inclined design. The opening of the side opening 82 close to one end of the inner slot 81 is larger than the opening at the other end. The position of the side opening 82 corresponds to the filling pad 13. Two pairs of side openings 82 are set on the outside of the reinforcing bolt 72. The locking bolt 83 is slidably inserted in the inner slot 81. One end of the puncture rod 85 is rotatably connected to the receiving groove 84, and a torsion spring is set at the rotating connection to give the puncture rod 85 an outward thrust. The other end of the puncture rod 85 is slidably inserted in the receiving groove 84 and punctures into the filling pad 13.

[0032] By setting the locking assembly 8, the piercing rod 85 passes through the storage groove 84 and is inserted into the filling pad 13, locking the fixing bolt 62 and the reinforcing bolt 72 with the filling pad 13. The piercing rod 85 is entangled by the fiber threads in the filling pad 13 and is difficult to move in a circular direction. This can prevent the fixing bolt 62 and the reinforcing bolt 72 from gradually loosening due to the vibration of the vehicle, resulting in a decrease in the connection stability of the components.

[0033] The locking assembly 8 further includes a limiting sleeve 86 disposed outside the fixing bolt 62 and the reinforcing bolt 72, an annular groove 87 provided outside the fixing bolt 62 and the reinforcing bolt 72, and an elastic ring 88 disposed inside the limiting sleeve 86; Specifically, the limiting sleeve 86 is wrapped around the outer side of the opening of the inner insertion slot 81 , the elastic ring 88 is inserted into the buckle ring groove 87 , and the locking bolt 83 is pressed against the surface of the limiting sleeve 86 .

[0034] By providing the limiting sleeve 86 , the limiting sleeve 86 limits the locking bolt 83 in the inner slot 81 , thereby preventing the locking bolt 83 from moving at will and ensuring the stability of the states of various components.

[0035] Based on Examples 1-2, the working principle of the aluminum alloy skeleton of a new energy vehicle instrument panel with a stable structure of the present invention is as follows: During installation, first fix the auxiliary mounting frame 4 and other small components to the outside of the main beam 1 by welding, then sleeve the filling pad 13 on the outside of the inner tube 12, and then sleeve the outer tube 11 on the outside of the filling pad 13. During this process, it is necessary to ensure that the fixing screw holes 61 and the fastening screw holes 71 on the outer tube 11, the inner tube 12, and the filling pad 13 are connected; screw the reinforcing bolt 72 into the fastening screw hole 71, and after the reinforcing bolt 72 is fully inserted, the piercing rod 85 on the outside of the locking bolt 83 is inserted. Press and retract it into the receiving groove 84, and then insert it into the receiving groove 84. During this process, the receiving groove 84 and the side opening 82 need to be misaligned. After the second section of the puncture rod 85 is also inserted into the inner slot 81, the locking bolt 83 is rotated to make the receiving groove 84 correspond to the puncture rod 85, and then the locking bolt 83 is completely pushed into the inner slot 81. During this process, the puncture rod 85 bounces into the side opening 82, and as the locking bolt 83 goes deeper, the puncture rod 85 is inserted into the filling pad 13 along the side opening 82.

[0036] The steering column bracket 2 and the support fixing frame 3 are respectively attached to the corresponding positions on the outside of the main beam 1, and then the fixing bolt 62 is screwed into the fixing screw hole 61. After the fixing bolt 62 is fully inserted, the piercing rod 85 on the outside of the locking bolt 83 is pressed and retracted into the receiving groove 84, and then inserted into the receiving groove 84. During this process, the piercing rod 85 bounces into the side opening 82, and as the locking bolt 83 goes deeper, the piercing rod 85 is inserted into the filling pad 13 along the side opening 82. After fixing with the fixing bolt 62 and the reinforcing bolt 72, the limiting sleeve 86 is respectively nested in the head of the fixing bolt 62 and the reinforcing bolt 72, so that the elastic ring 88 is stuck in the ring groove 87.

[0037] Move the side connection assembly 5 close to the main beam 1 , so that the fixed side plate 51 is sleeved on the outside of the outer tube 11 , and the inner support platform 53 is inserted into the inner tube 12 , and finally fixed with the fixing bolts 62 .

[0038] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
