This can reduce the weight of the control arm body 1 and the lower sealing plate 2, lower the raw material price, and lower the cost. In addition, the stamping material thickness can be reduced, and the production efficiency can be improved.

[0032] As shown in Figures 1-4 The control arm structure 100 according to an embodiment of the utility model includes a control arm body 1 and a reinforcing pipe 3.

[0033] The control arm structure 100 is a key component in the automobile suspension system, is connected between the vehicle wheel and the vehicle body, is responsible for transmitting various forces on the vehicle wheel, such as impact force and steering force, and ensures that the vehicle wheel moves along a certain track. The control arm body 1 is the main part of the control arm structure 100, which is responsible for transmitting various forces on the vehicle wheel (such as impact force and steering force) to the vehicle body, and ensures the driving stability and safety of the vehicle.

[0034] The lower side of the control arm body 1 is connected with a lower sealing plate 2, which can support and fix the lower part of the control arm body 1, enhance the overall strength of the control arm body 1, and improve the fatigue strength of the control arm body 1. In addition, the lower sealing plate 2 is used to close the lower space of the control arm body 1, prevent sundries or moisture from entering, and effectively protect the internal structure of the control arm body 1 from erosion by sundries or moisture, thereby prolonging the service life of the control arm structure 100.

[0035] The lower sealing plate 2 can be connected to the control arm body 1 by bolts or other fasteners, or the lower sealing plate 2 can be welded to the control arm body 1.

[0036] The reinforcing pipe 3 penetrates the control arm body 1 and the lower sealing plate 2 in sequence in the up-down direction, and at least part of the upper end of the reinforcing pipe 3 protrudes upward from the upper surface of the control arm body 1 and / or at least part of the lower end of the reinforcing pipe 3 protrudes downward from the lower surface of the lower sealing plate 2.

[0037] That is, only at least part of the upper end of the reinforcing pipe 3 can be arranged to protrude upward from the upper surface of the control arm body 1, or only at least part of the lower end of the reinforcing pipe 3 can be arranged to protrude downward from the lower surface of the lower sealing plate 2, or at least part of the upper end of the reinforcing pipe 3 can be arranged to protrude upward from the upper surface of the control arm body 1 and at least part of the lower end of the reinforcing pipe 3 can be arranged to protrude downward from the lower surface of the lower sealing plate 2, and the above-mentioned arrangements can realize the installation of the reinforcing pipe 3 relative to the control arm body 1 and the lower sealing plate 2, and the arrangement is various and can be flexibly selected.

[0038] Specifically, the control arm body 1 is located on the upper side of the lower sealing plate 2, the reinforcing pipe 3 penetrates the control arm body 1 and the lower sealing plate 2 in sequence in the up-down direction, and the reinforcing pipe 3 can be fixed relative to the control arm body 1 and the lower sealing plate 2 in the up-down direction, wherein at least part of the upper end of the reinforcing pipe 3 protrudes upward from the upper surface of the control arm body 1, which can well support and fix the reinforcing pipe 3, can improve the connection strength between the reinforcing pipe 3 and the control arm body 1, that is, the thickness of the control arm body 1 does not need to be set too large, which can reduce the weight of the control arm body 1, and at least part of the lower end of the reinforcing pipe 3 protrudes downward from the lower surface of the lower sealing plate 2, which can well support and fix the reinforcing pipe 3, can improve the connection strength between the reinforcing pipe 3 and the lower sealing plate 2, that is, the thickness of the lower sealing plate 2 does not need to be set too large, which can reduce the weight of the lower sealing plate 2, thereby reducing the overall weight of the control arm structure 100 while meeting the high-strength requirement of the control arm structure 100. The arrangement is simple and convenient to process.

[0039] Further, during the operation of the vehicle, the control arm structure 100 will always bear the vertical force transmitted from the wheel, and in the pit or lateral impact working condition, it will also bear the lateral impact in addition to the vertical force. Through the control arm structure 100 of the embodiment, the force transmission stability between the wheel and the vehicle body is good and the driving safety of the vehicle is high under different operating conditions.

[0040] In actual installation, the reinforcing pipe 3 can penetrate the lower sealing plate 2 and the control arm body 1 in sequence from the lower direction, and the reinforcing pipe 3 can also penetrate the control arm body 1 and the lower sealing plate 2 in sequence from the upper direction.

[0041] According to the control arm structure 100, the reinforcing pipe 3 is arranged to penetrate the control arm body 1 and the lower sealing plate 2 in the up-down direction, the overall strength of the control arm body 1 and the lower sealing plate 2 can be enhanced, the safety of vehicle driving can be improved, the thickness of the control arm body 1 and the lower sealing plate 2 can be reduced after meeting the strength of the control arm structure 100, the weight of the control arm body 1 and the lower sealing plate 2 can be reduced, the lightweight design can be realized, the raw material price is reduced, the cost is lower, the stamping material thickness can be reduced, the process problems such as cracking and wrinkling are not prone to occur in the stamping forming process, and the production efficiency and production quality are improved.

[0042] In some embodiments, at least part of the upper end of the reinforcing pipe 3 protrudes upward from the upper surface of the control arm body 1 by a height H1, and satisfies: H1≥6.0mm.

[0043] Specifically, as shown in Figure 2 the reinforcing pipe 3 penetrates the control arm body 1 and the lower sealing plate 2 in the up-down direction, and at least part of the upper end of the reinforcing pipe 3 protrudes from the upper surface of the control arm body 1, and the protruding height is H1 as indicated in Figure 2 , wherein H1 can take values of 6.0mm, 6.5mm, 7.0mm, 7.5mm, 8.0mm, etc., so that the height of the reinforcing pipe 3 protruding from the upper surface of the control arm body 1 is controlled to be greater than or equal to 6.0mm, that is, enough space is reserved between the upper end of the reinforcing pipe 3 and the upper surface of the control arm body 1, so as to facilitate welding of the reinforcing pipe 3 and the upper surface of the control arm body 1, and ensure firm and reliable welding. And enough space can effectively avoid process defects such as welding undercut, and improve the actual use cycle of the product.

[0044] Wherein, the height of the upper end of the reinforcing pipe 3 protruding from the upper surface of the control arm body 1 cannot be set too small, otherwise the welding will be unreliable, and process defects such as welding undercut will occur, affecting the connection strength of the reinforcing pipe 3 and the control arm body 1, and reducing the product use cycle. And the height of the upper end of the reinforcing pipe 3 protruding from the upper surface of the control arm body 1 cannot be set too large, although it can meet the welding conditions and welding strength, but it will cause the reinforcing pipe 3 to be too large in size, increase the weight of the reinforcing pipe 3, and may interfere with other structures, which is not conducive to the reasonable arrangement of multiple structures.

[0045] In other embodiments, at least part of the lower end of the reinforcing pipe 3 protrudes downward from the lower surface of the lower sealing plate 2 by a height H2, and satisfies: H2≥6.0mm.

[0046] Specifically, as shown in Figure 2 the reinforcing pipe 3 penetrates the control arm body 1 and the lower sealing plate 2 in the up-down direction, and at least part of the lower end of the reinforcing pipe 3 protrudes from the lower surface of the lower sealing plate 2, and the protruding height is H2 as indicated in Figure 2H2, wherein H2 can be 6.0 mm, 6.5 mm, 7.0 mm, 7.5 mm, 8.0 mm, etc., so that the height of the reinforcing pipe 3 protruding from the lower surface of the lower sealing plate 2 is controlled to be greater than or equal to 6.0 mm, that is, sufficient space is reserved between the lower end of the reinforcing pipe 3 and the lower surface of the lower sealing plate 2, so as to facilitate the welding of the reinforcing pipe 3 and the lower surface of the lower sealing plate 2, and ensure the welding to be firm and reliable. The sufficient space can effectively avoid process defects such as welding undercut, and improve the actual use cycle of the product.

[0047] The height of the lower end of the reinforcing pipe 3 protruding from the lower surface of the lower sealing plate 2 cannot be set too small, otherwise the welding will be unreliable, and process defects such as welding undercut will occur, which will affect the connection strength of the reinforcing pipe 3 and the lower sealing plate 2, and reduce the use cycle of the product. In addition, the height of the lower end of the reinforcing pipe 3 protruding from the lower surface of the lower sealing plate 2 cannot be set too large, otherwise although the welding condition and welding strength can be met, the size of the reinforcing pipe 3 will be too large, which will increase the weight of the reinforcing pipe 3, and may interfere with other structures, which is not conducive to the reasonable arrangement of multiple structures.

[0048] In some embodiments, the control arm body 1 and the lower sealing plate 2 jointly form an avoiding space 11, and the reinforcing pipe 3 is arranged in the avoiding space 11 and fixedly connected with the inner wall of the avoiding space 11.

[0049] Specifically, the avoiding space 11 is used for avoiding installation tools, and the avoiding space 11 is arranged on the control arm body 1 and the lower sealing plate 2 to jointly avoid the installation tools. The avoiding space 11 penetrates the control arm body 1 and the lower sealing plate 2 to realize the connection of the reinforcing pipe 3 in the avoiding space 11. Further, the reinforcing pipe 3 is arranged in the avoiding space 11 and fixedly connected with the inner wall of the avoiding space 11, so as to realize the installation of the reinforcing pipe 3, and the installation process is simple and convenient.

[0050] The reinforcing pipe 3 and the inner wall of the avoiding space 11 can be in clearance fit, so as to facilitate the connection of the reinforcing pipe 3 in the avoiding space 11. The reinforcing pipe 3 and the avoiding space 11 can also be in interference fit, and the connection of the two can be completed by press fitting process.

[0051] Therefore, by arranging the avoiding space 11 on the control arm body 1 and the lower sealing plate 2, the structural strength of the control arm body 1 and the lower sealing plate 2 at the avoiding space 11 can be reduced. By arranging the reinforcing pipe 3 in the avoiding space 11, the circumference of the avoiding space 11 can be supported to strengthen the strength of the avoiding space 11, and the reinforcing pipe 3 occupies small space, so the strength and fatigue resistance of the control arm body 1 and the lower sealing plate 2 can be efficiently improved in limited space.

[0052] The control arm body 1 and the lower sealing plate 2 are both configured in an arc shape, the avoiding space 11 is formed at the corner of the control arm body 1 and the lower sealing plate 2, and the reinforcing pipe 3 is also arranged at the corner of the control arm body 1 and the lower sealing plate 2, so that the structural strength of the corner of the control arm body 1 and the lower sealing plate 2 can be improved, and the force transmission stability of the control arm body 1 and the lower sealing plate 2 during vehicle driving can be improved.

[0053] In some embodiments, the reinforcing pipe 3 is connected to the inner wall of the avoiding space 11 by welding, and the reinforcing pipe 3 is formed with a welding reserved gap 31 which is discontinuous in the circumferential direction and extends in the axial direction.

[0054] In this way, the reinforcing pipe 3 and the inner wall of the avoiding space 11 can be fixedly connected by welding, the welding is firm and reliable, the connection strength of the reinforcing pipe 3 in the avoiding space 11 can be improved, and the welding reserved gap 31 is formed in the reinforcing pipe 3, so that the welding stress and heat generated during welding of the reinforcing pipe 3 and the avoiding space 11 can be buffered and released through the welding reserved gap 31, so as to effectively prevent welding deformation of the reinforcing pipe 3 and the avoiding space 11 during welding from affecting the related installation size, and improve the welding quality.

[0055] Specifically, the welding reserved gap 31 extends in the axial direction of the reinforcing pipe 3 and penetrates through both axial ends of the reinforcing pipe 3, so that the reinforcing pipe 3 is discontinuous in the circumferential direction, and thus the welding stress and heat generated during welding can be released in the axial direction and the radial direction of the reinforcing pipe 3 respectively through the welding reserved gap 31, so that the heat distribution in the reinforcing pipe 3 and the avoiding space 11 is uniform, and the welding deformation is reduced. Moreover, the structure is simple and convenient to process.

[0056] In the reinforcing pipe 3, the steel plate stamping forming process can be adopted, the production is convenient, the structure is simple, and the raw material cost can be reduced.

[0057] In some embodiments, the reinforcing pipe 3 is formed with an avoiding gap 32 for avoiding the stabilizer bar.

[0058] The stabilizer bar is an important component of the suspension system, which can improve the driving stability of the vehicle and reduce the roll amplitude. Figure 3 and Figure 4 As shown in the figures, the avoiding gap 32 can be arranged at the end of the reinforcing pipe 3, and during actual processing, the avoiding gap 32 can be formed by cutting part of the structure of the reinforcing pipe 3, and the size of the avoiding gap 32 needs to be greater than the size of the stabilizer bar, so as to effectively avoid the stabilizer bar, and the processing method is simple and has high production efficiency.

[0059] Thus, the reinforcing pipe 3 and the stabilizer bar can keep enough space by avoiding the gap 32, so as to prevent the interference and collision between the two during the driving of the vehicle, and help to reduce the wear and damage between the components, prolong the service life of the suspension system, and effectively avoid the abnormal noise caused by the interference and collision, so as to ensure the stability and comfort of the vehicle driving. And the gap 32 can facilitate the installation of the reinforcing pipe 3 and the stabilizer bar, so as to improve the coordination between the structures.

[0060] And the gap 32 can avoid the stabilizer bar, but will not affect the structural strength of the reinforcing pipe 3, and thus will not affect the reinforcing effect of the reinforcing pipe 3 on the control arm body 1 and the lower sealing plate 2.

[0061] In some embodiments, the gap 32 is connected to the upper end of the welding reserved gap 31, that is, the gap 32 is communicated with the welding reserved gap 31, so that the gap 32 can be machined by referring to the position of the welding reserved gap 31 during machining, which is simpler and more convenient, and the welding stress can be released by the gap 32.

[0062] And the above setting can make the gap 32 and the welding reserved gap 31 combined together, so that the machining of the two can be carried out at the same time. Specifically, the position of the gap 32 is located at the upper end of the welding reserved gap 31, so that the machining of the two features can be completed at one time during the machining process, which is simpler and shortens the machining time.

[0063] Wherein, the gap 32 can be arranged at any position of the reinforcing pipe 3, and the gap 32 can also be arranged at a position different from the welding reserved gap 31, and the setting mode is various and can be selected flexibly.

[0064] In some embodiments, the gap 32 is configured as a V-shaped gap, and the opening width of the V-shaped gap is configured to gradually increase upward.

[0065] Specifically, the gap 32 is connected to the upper end of the welding reserved gap 31, and the gap 32 is configured as a V-shaped gap, and the machining of the V-shaped gap is taken as the reference point, so that the machining of the gap 32 is simpler and more convenient. And as shown in Figure 3 the opening width of the V-shaped gap gradually increases from bottom to top, so that enough space can be formed at the upper end of the reinforcing pipe 3, which can effectively avoid the stabilizer bar. And the opening width of the V-shaped gap gradually increases from bottom to top, so that the structure of the reinforcing pipe 3 at the V-shaped gap is smooth and stable and reliable. Wherein, the opening angle of the V-shaped gap can be a right angle or an obtuse angle, and the specific setting angle is not limited and can be selected flexibly.

[0066] The avoidance gap 32 can also be configured as a U-shaped gap, a semicircular gap or other arc-shaped gap, and the setting mode is various, which can be selected flexibly according to actual needs.

[0067] In some embodiments, the width of the welding reserved gap 31 is a, and satisfies: 1.0mm≤a≤2.0mm, specifically, the width of the welding reserved gap 31 is a as marked in Figure 4 , and the width of the welding reserved gap 31 is its circumferential dimension of the reinforcing pipe 3. Wherein, a can be 1.0mm, 1.2mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2.0mm, etc., so that the reinforcing pipe 3 is reserved with a suitable width of the welding reserved gap 31, which is convenient for the welding connection of the reinforcing pipe 3 and the inner wall of the avoidance space 11, or the welding connection of the reinforcing pipe 3 and the control arm body 1 or the lower sealing plate 2, to ensure the firm and reliable welding. And enough space can effectively prevent the welding deformation of the reinforcing pipe 3 and the control arm body 1 during welding, to improve the welding quality.

[0068] Wherein, the width of the welding reserved gap 31 cannot be too small, otherwise the welding stress and temperature cannot be well released during the welding process, and welding deformation may occur. And the width of the welding reserved gap 31 cannot be too large, otherwise the strength of the reinforcing pipe 3 will be reduced, which does not meet the design requirements.

[0070] Specifically, the control arm structure 100 is used for connecting the auxiliary frame and the wheel, as shown in Figure 1 The first connecting portion 4 and the second connecting portion 5 can be arranged on the inner side of the control arm structure 100 and spaced apart in the front-rear direction, and the auxiliary frame is provided with corresponding connecting positions, so that the inner side of the control arm structure 100 can be connected with the auxiliary frame through the first connecting portion 4 and the second connecting portion 5.
