Description

Technical Field

[0001] This utility model relates to the field of automotive stabilizer bar technology, specifically a lateral stabilizer bar structure for new energy vehicles. Background Technology

[0002] Traditional automotive stabilizer bars, needing to withstand vibrations from the vehicle frame, require structural reinforcement to improve vibration resistance. A common approach is to increase the cross-sectional area of ​​the stabilizer bar and its support structure to enhance structural strength. However, this method leads to a significant increase in structural weight, which is unsuitable for lightweight designs in new energy vehicles. Therefore, we need to explore new structural designs that simultaneously improve the stabilizer bar's vibration resistance and achieve weight reduction.

[0003] Extensive searches revealed CN218577440U, which discloses a lateral stabilizer bar structure for new energy vehicles. This structure features high structural strength, good vibration resistance, weight reduction treatment to significantly reduce structural mass, and compliance with new energy vehicle specifications.

[0004] In existing technologies, stabilizer bars have relatively fixed dimensions, which means they can only be made for specific vehicles. This results in high costs during mold production. Furthermore, during installation, they must fit the vehicle frame perfectly; otherwise, stable installation is difficult. Consequently, thermal expansion and contraction can cause the vehicle frame to deform to some extent. Therefore, a new type of lateral stabilizer bar structure for new energy vehicles is needed to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lateral stabilizer bar structure for new energy vehicles, which has the advantages of convenient installation, adjustable size to a certain extent, and stretchability, thereby reducing the adverse effects of thermal expansion and contraction to a certain extent. It solves the problem that the size of the stabilizer bar in the prior art cannot be adjusted during use, resulting in poor product adaptability, and that it will cause certain damage to the vehicle frame under thermal expansion and contraction after fixed installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lateral stabilizer bar structure for a new energy vehicle, comprising a crossbar, wherein adjustment frames are fixedly installed at both ends of the crossbar, and the crossbar comprises a crossbar and two connecting frames fixedly connected to the crossbar via positioning frames;

[0007] The adjusting frame includes a connecting seat, one end of which is provided with a sleeve. The connecting seat is fitted onto both ends of the crossbar through the sleeve. The other end of the connecting seat is provided with a screw, and an adapter is movably fitted onto the screw.

[0008] Preferably, two limiting brackets are fixedly installed on the crossbar. These two limiting brackets are respectively fixedly installed on the crossbar on opposite sides of the two connecting brackets. A limiting groove is provided at the connection between the crossbar and the sleeve. In this design, the two limiting brackets fixedly installed on the crossbar are located on opposite sides of the two connecting brackets. This design not only enhances the overall structural strength of the crossbar but also provides physical constraints on the sliding of the adjusting bracket on the crossbar, preventing excessive sliding or detachment of the adjusting bracket under uncontrolled conditions. The limiting groove at the connection between the crossbar and the sleeve matches the fastening bolts. This design allows the user to fix or adjust the position of the sleeve on the crossbar by tightening or loosening the fastening bolts.

[0009] Preferably, the two connecting frames are mirror-distributed along the central axis of the crossbar, and both connecting frames have slots at their connections to the crossbar with embedded anti-slip pads. This mirror-distribution of the two connecting frames along the central axis of the crossbar ensures the lateral balance of the crossbar, improving overall stability and durability. The slots and embedded anti-slip pads at the connections effectively prevent the connecting frames from sliding or loosening on the crossbar, enhancing the stability of the connection.

[0010] Preferably, both positioning frames have grooves on their inner sides and are fitted with anti-slip pads of the same size as those on the connecting frame. Similar to the design of the connecting frame, the positioning frames also have grooves on their inner sides and are fitted with anti-slip pads. This design further enhances the stability of the connection between the positioning frames and the connecting frame, preventing loosening due to vibration or external forces.

[0011] Preferably, the connecting seat, sleeve, and screw adopt an integrated structural design. This integrated design not only simplifies the manufacturing process and reduces production costs, but also enhances the overall structural strength of the adjustment frame, making it more durable and reliable. Simultaneously, the integrated design reduces the number of connection points between components, thereby lowering the risk of failure due to loose connections.

[0012] Preferably, the sleeve has an expansion joint on the side opposite to the connecting seat, and a fastening bolt is threaded onto the side of the sleeve's outer wall with the expansion joint. The installation position of the fastening bolt matches the position of the limiting groove on the crossbar. The design of the expansion joint allows the sleeve to have a certain elastic deformation capacity when subjected to external forces, thereby mitigating the impact of thermal expansion and contraction on the structure to a certain extent. At the same time, the matching design of the fastening bolt and the limiting groove allows the user to fix or adjust the position of the sleeve by tightening or loosening the fastening bolt, realizing the function of fine adjustment of length.

[0013] Preferably, a limiting nut and a fastening nut are threaded onto the screws on both sides of the adapter frame, respectively. The adapter frame has radially spaced expansion joints on the side near the limiting nut, and the wall thickness at this end is relatively thin. The threaded installation of the limiting nut and fastening nut on the adapter frame allows users to fix or adjust the position of the adapter frame on the screws by adjusting the positions of the limiting nut and fastening nut, thereby achieving precise adjustment of the frame connection. The expansion joint design on the side of the adapter frame near the limiting nut allows the adapter frame to deform under the external force of the fastening nut, thus ensuring a tight fit with the limiting nut and mitigating the impact of thermal expansion and contraction on the structure to some extent. Simultaneously, the thinner wall thickness reduces the weight of the adapter frame, meeting the requirements of lightweight design for new energy vehicles, and also makes it easier to deform under stress, further mitigating the impact of its own thermal expansion and contraction on the structure.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention uses sleeves to mount the adjustment brackets to both ends of the crossbar. This design allows the adjustment brackets to be detached from the crossbar, thus providing some adaptability to thermal expansion and contraction between the sleeves and the crossbar. The adapter bracket is positioned on the screw rod by limiting nuts and fastening nuts, and is finally fixed by the fastening nuts. This design allows users to precisely adjust the position of the adapter bracket according to the mounting hole positions on the frame, ensuring that the stabilizer bar can be securely installed on the frame. The expansion joint on the side of the sleeve away from the connecting seat allows the sleeve to have a certain elastic deformation capacity under external force. This design mitigates the impact of thermal expansion and contraction on the structure to a certain extent, allowing the stabilizer bar to adapt to slight changes in the frame at different temperatures. The radial expansion joints on the side of the adapter bracket near the limiting nut, along with the thinner wall thickness, make the adapter bracket more easily deformable under the external force of the fastening nuts, thereby mitigating the impact of thermal expansion and contraction on the structure. In summary, this invention achieves the advantages of convenient installation, adjustable size, and expandability. These designs not only improve the adaptability of the stabilizer bar, but also reduce the adverse effects of thermal expansion and contraction on the frame, thus solving the problems in the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of this utility model is provided: a transverse stabilizer bar structure for a new energy vehicle, including a cross frame 1, with adjustment frames 2 fixedly installed at both ends of the cross frame 1. The cross frame 1 includes a cross bar 11 and two connecting frames 13 fixedly connected to the cross bar 11 through positioning frames 12.

[0024] The adjusting frame 2 includes a connecting seat 21. One end of the connecting seat 21 is provided with a sleeve 211. The connecting seat 21 is fitted onto both ends of the crossbar 11 through the sleeve 211. The other end of the connecting seat 21 is provided with a screw 212. An adapter 22 is movably fitted onto the screw 212.

[0025] Specifically, the adjustment bracket 2 is fitted onto both ends of the crossbar 11 via sleeves 211. This design allows the adjustment bracket 2 to be disassembled from the crossbar 11, thus enabling the sleeves 211 and the crossbar 11 to adapt to thermal expansion and contraction. The adapter bracket 22 is positioned on the screw 212 via limiting nuts 23 and fastening nuts 24, and is finally fixed by the fastening nuts 24. This design allows users to precisely adjust the position of the adapter bracket 22 according to the mounting hole positions on the frame, ensuring that the stabilizer bar can be securely installed on the frame. The expansion joint on the side of the sleeve 211 away from the connecting seat 21 allows the sleeve 211 to have a certain elastic deformation capacity when subjected to external forces. This design mitigates the impact of thermal expansion and contraction on the structure to some extent, enabling the stabilizer bar to adapt to slight changes in the frame at different temperatures. The radially arranged expansion joints and thinner wall thickness of the adapter frame 22 near the limiting nut 23 allow it to deform more easily under the external force of the fastening nut 24, thus mitigating the impact of thermal expansion and contraction on the structure. In summary, this invention achieves the advantages of convenient installation, adjustable size, and expandability. These designs not only improve the adaptability of the stabilizer bar but also reduce the adverse effects of thermal expansion and contraction on the frame, thereby solving the problems in the prior art.

[0026] Example 2

[0027] To improve the stability of the connection structure between the crossbeam and the frame, such as Figure 2 As shown, in this embodiment, two limiting brackets 14 are fixedly installed on the crossbar 11. The two limiting brackets 14 are respectively fixedly installed on the crossbar 11 on opposite sides of the two connecting brackets 13. A limiting groove 111 is provided at the connection between the crossbar 11 and the sleeve 211. In this design, the two limiting brackets 14 fixedly installed on the crossbar 11 are located on opposite sides of the two connecting brackets 13. This design not only enhances the overall structural strength of the crossbar 11, but also provides physical restriction for the sliding of the adjusting bracket 2 on the crossbar 11, preventing the adjusting bracket 2 from sliding excessively or falling off uncontrollably. The limiting groove 111 provided at the connection between the crossbar 11 and the sleeve 211 matches the fastening bolt 2111. This design allows the user to fix or adjust the position of the sleeve 211 on the crossbar 11 by tightening or loosening the fastening bolt 2111.

[0028] Furthermore, the two connecting frames 13 are mirror-distributed along the central axis of the crossbar 11. Both connecting frames 13 have slots at their connections to the crossbar 11, with anti-slip pads embedded within them. This mirror-distribution of the two connecting frames 13 along the central axis of the crossbar 11 ensures the left-right balance of the crossbar 1, improving overall stability and durability. The slots and embedded anti-slip pads at the connections between the connecting frames 13 and the crossbar 11 effectively prevent the connecting frames 13 from sliding or loosening on the crossbar 11, enhancing the stability of the connection.

[0029] Furthermore, both positioning frames 12 have grooves on their inner sides and are fitted with anti-slip pads of the same size as those on the connecting frame 13. Similar to the design of the connecting frame 13, the positioning frames 12 also have grooves on their inner sides and are fitted with anti-slip pads. This design further enhances the stability of the connection between the positioning frames 12 and the connecting frame 13, preventing loosening due to vibration or external forces.

[0030] Example 3

[0031] To facilitate the disassembly and reassembly of the adjustment frame and the crossbeam, and to make the connection position between the adjustment frame and the crossbeam adjustable, such as Figure 3 and Figure 4 As shown, in this embodiment, the connecting seat 21, sleeve 211, and screw 212 adopt an integrated structural design. This integrated design not only simplifies the manufacturing process and reduces production costs, but also enhances the overall structural strength of the adjusting frame 2, making it more durable and reliable. Simultaneously, the integrated structural design reduces the number of connection points between components, thereby reducing the risk of failure due to loose connections.

[0032] Furthermore, an expansion joint is provided on the side of the sleeve 211 away from the connecting seat 21. A fastening bolt 2111 is threaded onto the side of the outer wall of the sleeve 211 where the expansion joint is located. The installation position of the fastening bolt 2111 matches the position of the limiting groove 111 on the crossbar 11. The design of the expansion joint allows the sleeve 211 to have a certain elastic deformation capacity when subjected to external forces, thereby mitigating the impact of thermal expansion and contraction on the structure to a certain extent. At the same time, the matching design of the fastening bolt 2111 and the limiting groove 111 allows the user to fix or adjust the position of the sleeve 211 by tightening or loosening the fastening bolt 2111, realizing the function of fine adjustment of length.

[0033] Furthermore, limit nuts 23 and fastening nuts 24 are threaded onto the screws 212 on both sides of the adapter frame 22, respectively. The side of the adapter frame 22 near the limit nuts 23 has radially arranged expansion joints with a thinner wall thickness at that end. The threaded installation of the limit nuts 23 and fastening nuts 24 on the adapter frame 22 allows users to fix or adjust the position of the adapter frame 22 on the screws 212 by adjusting the positions of the limit nuts 23 and fastening nuts 24, thus achieving precise adjustment of the frame connection. The expansion joint design on the side of the adapter frame 22 near the limit nuts 23 gives the adapter frame 22 a certain deformation capacity when subjected to the external force of the fastening nuts 24, thus ensuring a tight fit with the limit nuts 23 and mitigating the impact of thermal expansion and contraction on the structure to some extent. Simultaneously, the thinner wall thickness reduces the weight of the adapter frame 22, meeting the requirements of lightweight design for new energy vehicles, and also makes it easier to deform under stress, thereby mitigating the impact of its own thermal expansion and contraction on the structure.

[0034] When using this invention, ensure that the vehicle frame of the new energy vehicle has a pre-reserved installation position that matches the lateral stabilizer bar structure. Check the integrity of the lateral stabilizer bar structure to ensure that all components are undamaged or missing. Measure the distance between the connection point between the vehicle frame and the stabilizer bar. First, install the limiting nut 23 on the screw 212 to easily adjust the position of the adapter 22 on the screw 212. Align the adapter 22 with the mounting hole on the vehicle frame, ensuring that the adapter 22 matches the position of the pre-reserved hole on the vehicle frame. Fine-tune the position of the limiting nut 23 as needed. Finally, install the fastening nut 24 on the other end of the screw 212 and tighten it to ensure that the adapter 22 is securely in place. With the position on the crossbar 11 unchanged, the adapter 22 is fixedly connected to the vehicle frame with bolts. It is confirmed that the lateral stabilizer bar structure is firmly installed on the vehicle frame and does not interfere with the normal operation of other components. The limit bracket 14 is loosened to adjust the position of the positioning bracket 12 and the connecting bracket 13 so that the hole on the connecting bracket 13 matches the reserved hole on the vehicle frame. Then the limit bracket 14 is tightened, and the connecting bracket 13 is fixedly connected to the crossbar 11 through the positioning bracket 12. The connecting bracket 13 is then fixedly connected to the vehicle frame with bolts. After all the installation is completed, the new energy vehicle is started and a test drive is conducted to check the working status of the lateral stabilizer bar structure.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
