In order to improve vehicle driving stability, modern automobiles mostly use stabilizer bar devices. Generally, the two ends of the stabilizer bar are connected to the steering knuckle or shock absorber bracket through the stabilizer bar connecting rod, so that when the vehicle rolls, it can generate a larger roll angle stiffness to resist the vehicle roll and improve vehicle stability.

[0003] In the prior art, stabilizer bar connecting rods are produced using prefabricated molding technology. Since automobile companies have a variety of vehicle models, they need to design stabilizer bar connecting rods of various lengths and installation directions during production, which results in a large number of production molds, resulting in high production costs and a long development cycle. Utility Model Content

[0004] The present application provides a variable structure stabilizer bar connecting rod, which aims to solve the problem in the prior art that in the production process of stabilizer bar connecting rods, a variety of stabilizer bar connecting rods with different lengths and installation directions need to be designed for a variety of vehicle models, resulting in a large number of production molds, high production costs and long development cycles.

[0005] A first aspect of the present application provides a variable structure stabilizer bar connecting rod, the variable structure stabilizer bar connecting rod comprising:

[0006] A dominant ball head rod, one end of which is provided with a tenon, and the cross-sectional shape of the tenon is an axisymmetric figure;

[0007] An auxiliary ball head rod, one end of which is provided with a tenon, the tenon comprising a groove adapted to the cross-sectional shape of the tenon, the tenon being engaged and inserted in the groove;

[0008] A sleeve, wherein the sleeve is sleeved at a position corresponding to the connection between the tenon and the insert tenon, and one end of the sleeve is fixedly connected to the main ball head rod, and the other end of the sleeve is fixedly connected to the auxiliary ball head rod.

[0009] According to the above-mentioned technical means, the embodiment of the present application can cooperate with the groove in the tenon of the auxiliary ball head rod through the tenon with a cross-sectional shape of an axisymmetric figure set on one end of the main ball head rod, so that the two can have a variety of combinations when combined, thereby forming various types of stabilizer bar connecting rods. When fixed by a sleeve, the combined distance between the two can be limited, so as to meet the requirements of the length of the stabilizer bar connecting rod of different types of vehicle models, reduce the number of production molds developed, and meet the use of various vehicle models.

[0010] Optionally, a first ball pin is disposed on the other end of the dominant ball rod, and the first ball pin is fixedly disposed with the dominant ball rod along a first predetermined angle;

[0011] A second ball pin is arranged on the other end of the auxiliary ball rod, and the second ball pin is fixedly arranged with the auxiliary ball rod along a second predetermined angle.

[0012] According to the above-mentioned technical means, in the embodiment of the present application, a first ball pin is provided on the other end of the dominant ball head rod, and the first ball pin is used to connect with other structures of the vehicle, and a second ball pin is provided on the other end of the auxiliary ball head rod, and the second ball pin is used to connect with other structures of the vehicle, thereby realizing the connection function of the stabilizer bar connecting rod in the vehicle. In this embodiment, the first ball pin and the dominant ball head rod are fixed at a first preset angle, and the second ball pin and the auxiliary ball head rod are fixed at a second preset angle. Therefore, when combining the combined effect of the dominant ball head rod and the auxiliary ball head rod, a variety of different types of stabilizer bar connecting rod structures can be formed, which can meet the use of various vehicle models.

[0013] Optionally, the tenon is arranged along the length direction of the main ball head rod; the tenon is arranged along the length direction of the auxiliary ball head rod; the cross-sectional shape of the tenon is a cross; the length dimension of the tenon is adapted to the depth dimension of the groove.

[0014] According to the above-mentioned technical means, in the embodiment of the present application, the tenon is arranged along the length direction of the dominant ball head rod, and the tenon is arranged along the length direction of the auxiliary ball head rod. When the dominant ball head rod and the auxiliary ball head rod are combined, stabilizer bar connecting rods of various lengths can be formed by limiting the depth of the combination of the tenon and the tenon. On the other hand, the cross-sectional shape of the tenon is a cross. When combined with the groove of the tenon, different combination states of 90 degrees, 180 degrees, and 270 degrees can be formed. Combined with the preset setting angles of the first ball pin and the second ball pin, stabilizer bar connecting rods with various orientations can be combined to meet the use requirements of different vehicle models.

[0015] Optionally, the length of the sleeve is twice the length of the tenon.

[0016] According to the above-mentioned technical means, in the embodiment of the present application, the sleeve serves as a reinforcement component for the connection portion between the main ball head rod and the auxiliary ball head rod. It is necessary to ensure that the length of the sleeve is greater than the connection size of the tenon and the plug tenon to ensure that both ends of the sleeve can be firmly fixed on the main ball head rod and the auxiliary ball head rod. Since the tenon and the plug tenon need to form a plug-in relationship to form a connection, the length of the sleeve is set to twice the length of the tenon in this embodiment, which can not only ensure the stability of the connection, but also will not add extra weight, thereby meeting the use requirements.

[0017] Optionally, a first adjusting rod is provided on the dominant ball head rod at a position corresponding to the tenon;

[0018] A second adjusting rod is provided on the auxiliary ball head rod at a position corresponding to the tenon;

[0019] The first adjusting rod and the second adjusting rod are respectively provided with threads, and the two ends of the sleeve are respectively rotatably connected to the threads on the first adjusting rod and the second adjusting rod.

[0020] According to the above-mentioned technical means, in the embodiment of the present application, the sleeve is fixedly connected with the main ball head rod and the auxiliary ball head rod by rotating, and by setting threads on the first adjusting rod and the second adjusting rod, the sleeve is rotated to be connected with the first adjusting rod and the second adjusting rod respectively during installation, which can be used to limit the distance between the first adjusting rod and the second adjusting rod, and is convenient for fine-tuning during the actual installation process, thereby avoiding poor installation due to tolerance problems.

[0021] Optionally, a first nut is rotatably sleeved on the first adjusting rod; a second nut is rotatably sleeved on the second adjusting rod; when the sleeve is installed on the first adjusting rod and the second adjusting rod, the first nut and the second nut respectively abut against two ends of the sleeve.

[0022] According to the above-mentioned technical means, in order to ensure that the sleeve is sufficiently stable after installation and to prevent the sleeve from rotating due to vibration, which causes the main ball head rod and the auxiliary ball head rod to change in length and separate, in the embodiment of the present application, a first nut and a second nut are also provided in the present embodiment, which are used to cooperate with the threads on the first adjusting rod and the second adjusting rod. After the installation position of the sleeve is determined, the sleeve is clamped by the first nut and the second nut to limit the positional relationship between the sleeve and the main ball head rod and the auxiliary ball head rod, thereby ensuring the safety and reliability of the stabilizer bar connecting rod during use.

[0023] Optionally, the thread on the first adjusting rod and the thread on the second adjusting rod are arranged in opposite directions.

[0024] According to the above-mentioned technical means, in the embodiment of the present application, the setting directions of the threads on the first adjusting rod and the second adjusting rod should be set to be opposite. The purpose of such setting is, on the one hand, to facilitate the simultaneous installation of the sleeve on the first adjusting rod and the second adjusting rod, and on the other hand, to facilitate the sleeve to fine-tune the distance between the main ball head rod and the auxiliary ball head rod, thereby facilitating the assembly personnel to operate.

[0025] Optionally, the lengths of the threads provided on the first adjusting rod and the second adjusting rod are both half of the length of the tenon;

[0026] The thread on the first adjusting rod is arranged on a side corresponding to the tenon;

[0027] The thread on the second adjusting rod is arranged on a side corresponding to the tenon.

[0028] According to the above-mentioned technical means, in the embodiment of the present application, the length of the thread on the first adjusting rod and the second adjusting rod is half of the length of the tenon. The reason is that when the dominant ball head rod and the auxiliary ball head rod are fully combined, that is, when the tenon is fully inserted into the groove of the tenon, the size of the sleeve corresponding to the tenon is half of the sleeve. In this fully combined state, the sleeve can be directly tightened with the threads on the dominant ball head rod and the auxiliary ball head rod. In this case, there is no need to use the first nut and the second nut. Therefore, in order to ensure the beautiful appearance of the combined stabilizer bar connecting rod, the length of the thread is limited to ensure the beauty of the stabilizer bar connecting rod.

[0029] Optionally, a plurality of identification grooves are respectively provided at positions corresponding to the thread settings on the first adjusting rod and the second adjusting rod, and the plurality of identification grooves are evenly arranged along the same straight line and at predetermined intervals, and the identification grooves are used to indicate the connection positions of the sleeves on the first adjusting rod and the second adjusting rod.

[0030] According to the above-mentioned technical means, in an embodiment of the present application, in order to facilitate the assemblers to pre-install stabilizer bar connecting rods of different lengths when assembling the stabilizer bar adjusting rod, in this embodiment, a plurality of identification grooves are preset at positions corresponding to the threaded settings on the first adjusting rod and the second adjusting rod. The plurality of identification grooves are used to identify the lengths of the stabilizer bar connecting rods corresponding to different positions during the sleeve connection process, thereby facilitating the assemblers to perform quick operations and avoiding repeated measurements.

[0031] A second aspect of the present application provides a vehicle, which includes the variable structure stabilizer bar connecting rod described in the above embodiment.

[0032] According to the above-mentioned technical means, the above-mentioned embodiments of the present application can be applied to the production and use of vehicles. Through the structural setting of the above-mentioned variable-structure stabilizer bar connecting rod, relatively few molds can be used to prefabricate standard parts of the main ball head rod and the auxiliary ball head rod, and then they can be assembled in accordance with the actual use requirements of different models with the sleeve. During the assembly process, various types of stabilizer bar connecting rods can be formed through combined angle restrictions and combined length restrictions, thereby meeting the use requirements of various different models and reducing the development cycle and mold production costs.

[0033] The beneficial effect of the utility model is that a tenon with a cross-section of an axisymmetric figure is arranged at one end of the dominant ball head rod, and a tenon with a groove is arranged at one end of the auxiliary ball head rod. The tenon with a cross-section of an axisymmetric figure and the tenon with a groove are combined at various angles to form different types of stabilizer bar connecting rods. After the combination, the distance is limited and the strength is guaranteed by connecting with a sleeve, so that a stabilizer bar connecting rod that meets the size requirements of different vehicle models can be formed. The utility model can reduce the number of mold development and reduce costs, shorten the development cycle, and meet the production needs of various different vehicle models.

DETAILED DESCRIPTION

[0042] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0043] The following is an explanation of the variable structure stabilizer bar connecting rod of the embodiment of the present application with reference to the accompanying drawings. In view of the related art mentioned in the background art, the stabilizer bar connecting rod is produced by prefabrication molding technology. Since the automobile enterprises have a variety of models, it is necessary to design a variety of stabilizer bar connecting rods with different lengths and installation directions during production, which leads to a large number of production molds, high production costs, and long development cycles. The present application provides a variable structure stabilizer bar connecting rod, which can be formed by setting a tenon 110 with a cross section of an axisymmetric figure at one end of the leading ball head rod 100, and setting a tenon 210 with a groove 211 at one end of the auxiliary ball head rod 200. The tenon 110 with a cross section of an axisymmetric figure and the tenon 210 with a groove 211 are combined at various angles to form different types of stabilizer bar connecting rods. After the combination, the distance is limited and the strength is guaranteed by connecting through the sleeve 300, so as to form a stabilizer bar connecting rod that meets the size requirements of different models. Thus, the problems of various types of stabilizer bar connecting rods, long development cycles, and high costs in the related art are solved.

[0044] See also Figure 1 and Figure 7The present application provides some embodiments of a variable structure stabilizer bar connecting rod, wherein the main body of the variable structure stabilizer bar connecting rod is composed of a dominant ball head rod 100, an auxiliary ball head rod 200 and a sleeve 300, wherein the dominant ball head rod 100 and the auxiliary ball head rod 200 are used to connect with other structures of the vehicle, such as a steering knuckle or a shock absorber bracket, etc. In actual production, the dominant ball head rod 100 is a prefabricated standard part, and a tenon 110 is provided on one end of the dominant ball head rod 100. The tenon The cross-sectional shape of 110 is an axisymmetric figure, for example, it can be specifically set to a cross, a triangle, other regular polygons, etc.; correspondingly, the auxiliary ball head rod 200 is also a prefabricated standard part, and a tenon 210 is provided on one end of the auxiliary ball head rod 200, and a groove 211 is provided on the tenon 210. The cross-sectional shape of the groove 211 is adapted to the cross-sectional shape of the tenon 210. During actual installation, the above-mentioned tenon 110 can be plugged and installed in the tenon 210 to provide axial limiting fixation.

[0045] In this embodiment, since the grooves 211 in the tenon 110 and the plug 210 are axially symmetrical figures with matching shapes, a variety of installation angles can be formed during actual installation. For example, when the cross-sectional shape of the tenon 110 is a cross, there are installation states of 0 degrees, 90 degrees, 180 degrees and 270 degrees. When the cross-sectional shape of the tenon 110 is a triangle, there are installation states of 0 degrees, 120 degrees and 240 degrees. When the cross-sectional shape of the tenon 110 is other regular polygons, there are also a variety of installation angles. Therefore, a combination of various angles between the end of the main ball head rod 100 and the end of the auxiliary ball head rod 200 can be formed to meet the use requirements of various vehicle designs.

[0046] Furthermore, since the tenon 210 and the latch 110 are plug-in connections, the cross-section of the axially symmetrical design can only provide an axial limiting effect. Therefore, in order to ensure the connection stability of the dominant ball head rod 100 and the auxiliary ball head rod 200, in this embodiment, a further combination is performed through a sleeve 300. Specifically, the sleeve 300 is sleeved at the position corresponding to the connection between the latch 110 and the tenon 210, and in actual setting, one end of the sleeve 300 is fixedly connected to the dominant ball head rod 100, and the other end of the sleeve 300 is fixedly connected to the auxiliary ball head rod 200, which can achieve the effect of limiting the relative position between the dominant ball head rod 100 and the auxiliary ball head rod 200, so that a stable installation whole is formed between the dominant ball head rod 100 and the auxiliary ball head rod 200, thereby achieving the effect of replacing the stabilizing rod connecting rod in the prior art.

[0047] In this embodiment, when installing the dominant ball head rod 100 and the auxiliary ball head rod 200, the assembler can select the prefabricated dominant ball head rod 100 and the auxiliary ball head rod 200 according to the requirements of the current production model, and make the tenon 110 on the dominant ball head rod 100 correspond to the tenon 210 on the auxiliary ball head rod 200, so that the tenon 110 is inserted into the groove 211 of the tenon 210 to form a connection. In this process, the sleeve 300 is sleeved at the connection position of the tenon 110 and the tenon 210. By connecting the tenon 110 and the tenon 210, the sleeve 300 is connected to the groove 211 of the tenon 210. 210 is combined to a predetermined position, and is fixedly connected with the main ball head rod 100 and the auxiliary ball head rod 200 through the sleeve 300, so as to complete the assembly of the main ball head rod 100 and the auxiliary ball head rod 200. It is worth noting that when the main ball head rod 100 and the auxiliary ball head rod 200 are fixed by the sleeve 300, the distance between the main ball head rod 100 and the auxiliary ball head rod 200 can also be limited by the sleeve 300 to adjust the length of the assembled stabilizer bar connecting rod, thereby realizing the production of more models of stabilizer bar connecting rods.

[0048] The variable structure stabilizer bar connecting rod of the present application can be stored through prefabrication. When meeting the production needs of different models, it only needs to be assembled according to the needs to meet the assembly needs of different models. Since there is no need to prefabricate various types of stabilizer bar connecting rods, it is only necessary to make molds for the main ball head rod 100, the auxiliary ball head rod 200 and the sleeve 300. In actual production, there is no need to adjust the mold for the stabilizer bar connecting rod of various models, which effectively shortens the development cycle and saves production costs, and meets the production needs of various types of automobiles.

[0049] In one implementation of the present application, refer to Figure 1 A first ball stud 120 is provided on the other end of the dominant ball stud rod 100, and the first ball stud 120 is fixedly connected to the dominant ball stud rod 100 along a first predetermined angle. Correspondingly, a second ball stud 220 is provided on the other end of the auxiliary ball stud rod 200, and the second ball stud 220 is fixedly connected to the auxiliary ball stud rod 200 along a second predetermined angle. In actual use, the first ball stud 120 and the second ball stud 220 are both used to connect with other functional components on the vehicle, such as a steering knuckle or a shock absorber bracket, etc. In this embodiment, refer to Figure 1 and Figure 5 The first predetermined angle has two types: 90 degrees and 0 degrees. When the first predetermined angle is 90 degrees, the first ball stud 120 and the leading ball stud rod 100 are in a vertical state, that is, corresponding to Figure 1 When the first predetermined angle is 0 degrees, the first ball stud 120 and the leading ball stud rod 100 are coaxial, that is, corresponding to Figure 5 The style shown; correspondingly, the second predetermined angle also has two types: 90 degrees and 0 degrees, which will not be repeated here.

[0050] In this embodiment, since the tenon 110 of the main ball head rod 100 and the tenon 210 of the auxiliary ball head rod 200 have various assembly angles, the cross-sectional shape of the tenon 110 is taken as an example;

[0051] When the main ball stud 100 and the auxiliary ball stud 200 are assembled with the first predetermined angle and the second predetermined angle both being 90 degrees, the first ball stud 120 and the second ball stud 220 can be formed to be parallel in the same direction (see Figure 2 ), the first ball stud 120 is perpendicular to the second ball stud 220 (see Figure 3 ), the first ball stud 120 is anti-parallel to the third ball stud (see Figure 4 ), and the first ball stud 120 is perpendicular to the second ball stud 220 (with Figure 2 reverse).

[0052] When the main ball stud 100 and the auxiliary ball stud 200 are assembled with the first predetermined angle of 0 degrees and the second predetermined angle of 90 degrees, the first ball stud 120 and the second ball stud 220 can be formed to be perpendicular (see FIG. Figure 5 ) structural style.

[0053] Similarly, when the first predetermined angle is 90 degrees and the second predetermined angle is 0 degrees, or the first predetermined angle is 0 degrees and the second predetermined angle is 0 degrees, different structural combination styles can be formed, which will not be described in detail here.

[0054] It can be seen that by presetting the dominant ball head rod 100 with the first ball head pin 120 at different predetermined angles, and the auxiliary ball head rod 200 with the second ball head pin 220 at different predetermined angles, different types of stabilizer bar connecting rods can be formed in combination with the unique design of the tenon 110 and the tenon 210, thereby being able to meet the different design requirements of different vehicle models. On the other hand, since the cross-sectional shape of the tenon 110 is an axially symmetrical figure, the cross-sectional shape of the groove 211 in the tenon 210 is adapted to the cross-sectional shape of the tenon 110, so when a cross-shaped or regular polygonal cross-sectional shape is adopted, it can also play a role in resisting torsion. Under the combined fixing action of the sleeve 300, deformation of the connecting portion of the dominant ball head rod 100 and the auxiliary ball head rod 200 can be avoided, thereby meeting the use requirements of various vehicle models.

[0055] In one implementation of the present application, refer to Figure 1The above-mentioned tenon 110 should be arranged along the length direction of the main ball head rod 100 when actually set, and correspondingly, the above-mentioned tenon 210 should be arranged along the length direction of the auxiliary ball head rod 200 when actually set. The purpose of such arrangement is to make the main ball head rod 100 and the auxiliary ball head rod 200 plug and unplug and connect along the length direction. When the sleeve 300 is combined, the combination depth of the tenon 110 and the tenon 210 can be limited according to actual use requirements, thereby forming more types of stabilizing rod connecting rods of different lengths.

[0056] In this embodiment, the cross-sectional shape of the latch 110 is set to be a cross shape, and correspondingly, the cross-sectional shape of the groove 211 in the tenon 210 is also a cross shape. The length dimension of the latch 110 is adapted to the depth dimension of the groove 211. Therefore, the combination of the latch 110 and the tenon 210 has two states: complete combination and incomplete combination. The complete combination means that the latch 110 is completely inserted into the groove 211 of the tenon 210, and the incomplete combination means that a part of the latch 110 is inserted into the groove 211 of the tenon 210 (see Figure 6 ), for these two states, it can play the effect of adjusting the length of the combined variable structure stabilizer bar connecting rod, and for these two states, the fixed connection positions of the sleeve 300 and the main ball head rod 100 and the auxiliary ball head rod 200 are different, so as to achieve the effect of fixed limiting. In this embodiment, no matter what the combination state is, the tenon 110 and the plug tenon 210 can achieve the effect of anti-torsion, that is, to ensure that the relative angle of the first ball head pin 120 and the second ball head pin 220 is fixed, and the stability of the use of the variable structure stabilizer bar connecting rod is guaranteed under the action of the fixed connection of the sleeve 300.

[0057] In one implementation of the present application, refer to Figure 1 The length of the sleeve 300 is twice the length of the tenon 110. The reason is that when the main ball head rod 100 and the auxiliary ball head rod 200 are connected, there are two limit states, one of which is that the tenon 110 is completely inserted into the tenon 210; the other is that a small part of the tenon 110 is inserted into the tenon 210. These two limit states are the length adjustment range of the variable structure stabilizer rod connecting rod of the present application. When the tenon 110 is completely inserted into the tenon 210, the connection between the tenon 110 and the tenon 210 is The connection part corresponds to half the length of the sleeve, so the sleeve still has a quarter of the length at both ends for connecting with the main ball head rod 100 and the auxiliary ball head rod 200, which can ensure the stability of the connection; when a small part of the tenon 110 is inserted into the internal tenon 210, the length of the combination of the tenon 110 and the tenon 210 must be less than 2 times the length of the tenon 110, that is, the sleeve still has a margin for connecting with the main ball head rod 100 and the auxiliary ball head rod 200, thereby ensuring the stability of the connection.

[0058] In this embodiment, the limit state in which a small part of the latch 110 is inserted into the interior of the insert 210 should be preset by the technician with reference to factors such as material strength and structural strength, and this application does not limit this.

[0059] In one implementation of the present application, refer to Figure 1 In order to realize the structural state of fixedly connecting the dominant ball head rod 100 and the auxiliary ball head rod 200 through the tube sleeve in the above embodiment, a first adjusting rod 130 is provided at a position corresponding to the tenon 110 on the dominant ball head rod 100, and correspondingly, a second adjusting rod 230 is provided at a position corresponding to the tenon 210 on the auxiliary ball head rod 200, and threads 310 are provided on both the first adjusting rod 130 and the second adjusting rod 230, and threads 310 are respectively provided inside the two ends of the sleeve 300, so that a rotational connection can be formed with the threads 310 on the first adjusting rod 130 and the second adjusting rod 230, so as to form a structural style that can be quickly assembled and has a stable connection state.

[0060] During actual installation, the dominant ball head rod 100 and the auxiliary ball head rod 200 are pre-adjusted to the required angles, and a sleeve 300 is sleeved on the outer side of the connection between the dominant ball head rod 100 and the auxiliary ball head rod 200. While rotating the sleeve 300, the dominant ball head rod 100 and the auxiliary ball head rod 200 are relatively close, and the tenon 110 is inserted into the insert tenon 210 to achieve a stable connection state. By controlling the combined depth between the sleeve 300 and the first adjustment rod 130 and the second adjustment rod 230, the length of the variable stabilizer rod connecting rod is adjusted, and the limiting and fixation of the combined components in the stabilizer rod connecting rod are achieved.

[0061] In one implementation of the present application, refer to Figure 1 In order to further improve the combined stability of the variable structure stabilizer rod connecting rod, in the present embodiment, a first nut 400 is rotatably sleeved on the first adjusting rod 130, and correspondingly, a second nut 500 is rotatably sleeved on the second adjusting rod 230. After the sleeve 300 is installed on the first adjusting rod 130 and the second adjusting rod 230, when it is adjusted to a preset distance, the first nut 400 can be rotated to make the first nut 400 abut and fix one end of the sleeve 300, and the second nut 500 can be rotated to make the second nut 500 abut and fix the other end of the sleeve 300. Therefore, in actual use, the first nut 400 and the second nut 500 can prevent the sleeve from rotating due to vibration by limiting the position and the friction with the end of the sleeve, thereby effectively ensuring the reliable performance of the variable structure stabilizer rod connecting rod.

[0062] In one implementation of the present application, refer to Figure 1In the specific setting, the setting direction of the thread 310 on the first adjusting rod 130 is opposite to that of the thread 310 on the second adjusting rod 230. The advantage of such a setting is that it is convenient for connecting the sleeve 300 with the first adjusting rod 130 and the second adjusting rod 230, and it is convenient to adjust the distance between the main ball head rod 100 and the auxiliary ball head rod 200 through the sleeve 300.

[0063] In specific use, when the dominant ball head rod 100, the auxiliary ball head rod 200 and the sleeve 300 are combined, the dominant ball head rod 100 and the auxiliary ball head rod 200 are first adjusted to a preset angle, and the tenon 110 is made to correspond to the insert tenon 210. After the sleeve 300 is installed, the sleeve 300 is rotated in a predetermined direction, and the two ends of the sleeve 300 are respectively combined with the threads 310 on the first adjustment rod 130 and the second adjustment rod 230, and the dominant ball head rod 100 and the auxiliary ball head rod 200 are relatively moved under the rotation drive of the sleeve 300. , forming the adjustment of the tenon 110 in the groove 211 of the inserting tenon 210 to different depths; when it is necessary to adjust the length of the variable structure stabilizing rod connecting rod, since the setting directions of the threads 310 on the first adjusting rod 130 and the second adjusting rod 230 are opposite, it is only necessary to rotate in a predetermined direction to make the main ball head rod 100 and the auxiliary ball head rod 200 relatively close. When it is necessary to increase the length of the variable structure stabilizing rod connecting rod, the sleeve 300 is rotated in the opposite direction to make the main ball head rod 100 and the auxiliary ball head rod 200 relatively far away.

[0064] In one implementation of the present application, refer to Figure 1 In order to facilitate the assemblers to quickly adjust the length of the variable structure stabilizer rod connecting rod, in the present embodiment, a plurality of identification grooves 311 are respectively arranged at the positions corresponding to the settings of the threads 310 on the first adjustment rod 130 and the second adjustment rod 230. The identification grooves 311 are specifically grooves, which are arranged on the surfaces of the first adjustment rod 130 and the second adjustment rod 230, and do not affect the settings of the threads 310. In actual settings, the plurality of identification grooves 311 are evenly arranged along the same straight line and at predetermined intervals. In specific settings, the identification grooves 311 correspond to the length adjustment positions of the commonly used stabilizer rod connecting rod models. When the assemblers rotate the sleeve 300, the end of the sleeve 300 corresponds to the position of the identification groove 311. The assemblers can quickly adjust to the required length by referring to the corresponding relationship between the position of the identification groove 311 and the end of the sleeve 300, thereby achieving the effect of quickly adjusting the variable structure stabilizer rod connecting rod to the predetermined length and improving the assembly efficiency.

[0065] In one implementation of the present application, refer to Figure 1The length of the thread 310 on the first adjusting rod 130 and the second adjusting rod 230 is half of the length of the tenon 110, and the thread 310 on the first adjusting rod 130 is arranged on one side of the corresponding tenon 110, and the thread 310 on the second adjusting rod 230 is arranged on one side of the corresponding tenon 210. The advantage of such a setting is that the sleeve 300 can be quickly combined with the thread 310 arranged on the first adjusting rod 130 and the thread 310 on the second adjusting rod 230 during assembly to correct the installation position; when the length of the thread 310 is set to half of the length of the tenon 110, since the length of the sleeve 300 is twice the length of the tenon 110, and the maximum distance between the end of the sleeve 300 and the thread 310 on one side is one quarter of the length of the sleeve 300, when the tenon 110 and the tenon 210 are fully inserted into the assembled state, the sleeve The tube 300 just forms a complete screw-on with the threads 310 at both ends. In this embodiment, the first nut 400 and the second nut 500 are not required, and the surface of the assembled variable structure stabilizing rod connecting rod has no threads 310, which can maintain the appearance and also ensure that the threads 310 are not damaged due to unexpected situations; when the tenon 110 and the plug tenon 210 are not fully inserted into the combined state, the sleeve 300 and the threads 310 at both ends are not fully screwed together. In this embodiment, after the sleeve 300 is combined, the surfaces of the first adjustment rod 130 and the second adjustment rod 230 still have threads 310. This state corresponds to the assembly of the first nut 400 and the second nut 500, which are combined with the threads 310 on the first adjustment rod 130 and the second adjustment rod 230 to form a clamping limit for the sleeve 300. The surface of the assembled variable structure stabilizing rod connecting rod also has no threads 310, which ensures beauty while preventing the threads 310 from being damaged due to accidental bumps.

[0066] In one implementation of the embodiment of the present application, when the cross-sectional shape of the tenon 110 is set to a cross shape, the designer can also set a guide portion on the side of the end of the tenon 110, that is, a slope inclined at a certain angle. The advantage of such a setting is that it can assist in inserting the tenon 110 into the interior of the plug 210 during assembly, thereby avoiding the situation where the tenon 110 and the plug 210 cannot be assembled due to a slight misalignment between the tenon 110 and the plug 210.

[0067] Based on the above embodiments, the actual use process of the variable structure stabilizer bar connecting rod of the utility model is as follows:

[0068] First, refer to Figure 1 , select the required types of the main ball head rod 100 and the auxiliary ball head rod 200, and make the tenon 110 on the main ball head rod 100 correspond to the tenon 210 on the auxiliary ball head rod 200, and sleeve the sleeve 300 at the corresponding positions of the tenon 110 and the tenon 210, so that the two ends of the sleeve 300 correspond to the threads 310 on the first adjustment rod 130 and the second adjustment rod 230 respectively;

[0069] Then rotate the sleeve 300 in a predetermined direction so that both ends of the sleeve 300 cooperate with the thread 310 respectively. When the sleeve 300 rotates relative to the main ball head rod 100 and the auxiliary ball head rod 200, the main ball head rod 100 and the auxiliary ball head rod 200 move toward each other, and finally the tenon 110 is completely inserted into the groove 211 of the tenon 210, thereby completing the assembly of the variable structure stabilizer rod connecting rod.

[0070] In the case where the length of the variable structure stabilizer rod connecting rod needs to be adjusted, the first nut 400 is pre-set on the first adjustment rod 130, and the second nut 500 is pre-set on the second adjustment rod 230. On the basis of the above-assembled stabilizer rod connecting rod, the sleeve 300 is rotated in the opposite direction to make the main ball head rod 100 and the auxiliary ball head rod 200 move in opposite directions. Combined with the corresponding relationship between the identification groove 311 set on the first adjustment rod 130 and the second adjustment rod 230 and the end of the sleeve 300, the variable structure stabilizer rod connecting rod is adjusted to a suitable length. At this time, the tenon 110 is not completely combined with the plug tenon 210 (see Figure 6 ), and finally rotate the first nut 400 and the second nut 500 so that the first nut 400 and the second nut 500 respectively abut and fix the two ends of the sleeve 300, thereby completing the assembly of the variable structure stabilizer rod connecting rod.

[0071] In addition, see Figures 1 to 6 Based on the variable structure stabilizer bar connecting rod of any of the above embodiments, the present application also provides a vehicle, which includes the variable structure stabilizer bar connecting rod of the above embodiment, referring to Figure 7 The variable structure stabilizer bar connecting rod is applied to the connecting structure in the vehicle production and assembly process, for example, it can be used for connecting the steering knuckle or the shock absorber bracket.
