Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0027] Referring to "embodiment" herein means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art understand explicitly and implicitly that the embodiments described herein can be combined with other embodiments.

[0028] Next, the suspension rod system auxiliary tool provided by the present invention will be described in detail in conjunction with the embodiments.

[0029] Please refer to Figures 1 to 3 , Figure 1 It is a structural schematic view of an embodiment of the subframe of the present application; Figure 2 It isFigure 1 Schematic structural diagram of A shown Figure 3 It is a schematic structural diagram of an embodiment of the suspension rod system auxiliary tool of the present application. The present application provides a suspension rod system auxiliary tool. In the multi-link suspension rod system, the swing arm 32 and the mounting portion 311 in the subframe 31 are connected by fasteners such as bolts 22 and nuts 21. The suspension rod system auxiliary tool 10 is used to fix the nut 21 to realize the fixation of the bolt 22 and the nut 21.

[0030] Specifically, the suspension rod system auxiliary tool 10 includes a fixed seat 11. The fixed seat 11 includes a first end face 11a and a second end face 11b arranged opposite to each other. The second end face 11b is provided with a fixing portion (not shown in the figure). The fixing portion can be used to install the nut 21. The fixed seat 11 is penetrated with a first fixing hole 112. The first fixing hole 112 can be used to pass through the bolt 22. The fixing portion is communicated with the first fixing hole 112, that is, after the bolt 22 passes through the nut 21, at least part of the bolt 22 can enter the first fixing hole 112, and the first fixing hole 112 can play a role in avoiding the bolt 22.

[0031] The suspension rod system auxiliary tool 10 further includes an auxiliary positioning assembly 12. The number of the auxiliary positioning assemblies 12 can be but is not limited to one group, two groups, three groups, four groups or more. In this embodiment, the number of the auxiliary positioning assemblies 12 is three groups. Each auxiliary positioning assembly 12 includes a positioning member 121 and a driving member 122. The positioning member 121 passes through the fixed seat 11. The positioning member 121 includes a first end 121a and a second end 121b arranged opposite to each other. The first end 121a protrudes from the first end face 11a. The second end 121b protrudes from the second end face 11b. The positioning member 121 plays a positioning role. Among them, the second end 121b of the positioning member 121 is used to be inserted into the mounting portion 311 in the subframe 31 to limit the suspension rod system auxiliary tool 10 on the mounting portion 311 in the subframe 31.

[0032] The driving member 122 is arranged on the first end face 11a of the fixed seat 11. For example, the driving member 122 is detachably or fixedly connected to the first end face 11a of the fixed seat 11. At the same time, the driving member 122 is connected to the positioning member 121. The driving member 122 plays a driving role. The driving member 122 drives the positioning member 121 to move in the first direction so that the fixed seat 11 stably abuts against the mounting portion 311 in the subframe 31. Among them, the first direction can be but is not limited to the length extension direction of the positioning member 121.

[0033] Thus, through the cooperation of the positioning member 121 and the driving member 122 in the fixing base 11 and the auxiliary positioning assembly 12, the fixing base 11 is stably abutted against the mounting portion 311 in the subframe 31. When the local mounting position is limited, the positioning and fixing between the nut 21 and the mounting portion 311 in the subframe 31 can also be achieved, so that the bolt 22 is tightened and fixed, thereby reducing the phenomenon that the nut 21 rotates with the bolt 22, and further improving the assembly efficiency and rhythm.

[0034] Please refer to Figure 4 and Figure 5 , Figure 4 which is an exploded schematic view of an embodiment of the suspension rod system auxiliary tool of the present application; Figure 5 which is a structural schematic view of the fixing base in the suspension rod system auxiliary tool of the present application. Combining Figures 1 to 3 , the above-mentioned fixing portion can be an integral structure with the fixing base 11 or a split structure. In addition, the fixing portion can protrude from the second end face 11b of the fixing base 11; or, the fixing portion can be recessed in the second end face 11b of the fixing base 11.

[0035] In this embodiment, the fixing portion is recessed in the second end face 11b of the fixing base 11. For example, the fixing portion is a fixing groove 111. That is, the fixing groove 111 is provided on the second end face 11b. The fixing groove 111 communicates with the first fixing hole 112. The shape of the fixing groove 111 matches the shape of the nut 21. The nut 21 is installed or clamped through the fixing groove 111, etc. By directly providing the above-mentioned fixing groove 111 on the second end face 11b of the fixing base 11, not only the structure is simple and easy to process, but also the stability of installing the nut 21 can be improved. The shapes of the above-mentioned fixing groove 111 and the nut 21 are the same, and both are hexagonal.

[0036] In addition, the above-mentioned fixing base 11 is a casting base, and its own structure has relatively high strength, which can improve the overall strength of the suspension rod system auxiliary tool 10, and further improve the service life of the suspension rod system auxiliary tool 10, etc.

[0037] Please refer to Figure 6 , Figure 6 which is a structural schematic view of the positioning member in the suspension rod system auxiliary tool of the present application. Combining Figures 1 to 5 , in some embodiments, the auxiliary positioning assembly 12 further includes a switch member 123. The switch member 123 is connected to the driving member 122. Through the switch member 123, the opening or closing of the driving member 122 can be directly controlled, which is not only easy to quickly start the operation of the suspension rod system auxiliary tool 10 in a narrow space, improve the assembly efficiency and rhythm, but also has a simple structure and is easy to implement, etc.

[0038] The above-mentioned switch member 123 can be arranged on the first end face 11a of the fixed seat 11, or on the outer periphery of the driving member 122, or at any position such as the positioning member 121, which is not limited herein. In a specific embodiment, an installation hole 12111 is formed at the end of the first end 121a of the positioning member 121. The installation hole 12111 provides an installation position for the switch member 123. By arranging the switch member 123 in the installation hole 12111 at the second end 121b of the positioning member 121, it is not only easier to quickly start the operation of the suspension rod system auxiliary tool 10 in a narrow space, improving the assembly efficiency and rhythm, but also has a simple structure and is easy to implement, etc.

[0039] The above-mentioned switch member 123 is installed in the installation hole 12111. The switch member 123 is at least arranged in the installation hole 12111, and at least a part of it protrudes out of the installation hole 12111, which is convenient for the user to activate the switch member 123, etc. Among them, the working principle of the electrical connection between the switch member 123 and the driving member 122 is common technology for those skilled in the art and is not limited herein.

[0040] In some embodiments, the driving member 122 is sleeved on the positioning member 121, which can not only drive the positioning member 121 to move in the first direction, but also limit the movement direction of the positioning member 121, reducing the risk of movement deviation of the positioning member 121, etc.

[0041] Specifically, the driving member 122 includes a driving housing 1221 and a hollow rotor shaft (not shown in the figure). The driving housing 1221 is connected to the hollow rotor shaft. The driving housing 1221 is connected to the first end face 11a of the fixed seat 11 so that the driving member 122 is stably connected to the first end face 11a of the fixed seat 11. The hollow rotor shaft is connected to the positioning member 121 so that the hollow rotor shaft drives the positioning member 121 to move in the first direction. Further, the positioning member 121 is a sliding screw rod (not shown in the figure), and a transmission connection is formed between the hollow rotor shaft and the sliding screw rod through a threaded fit so that the positioning member 121 moves in the first direction.

[0042] The above-mentioned driving housing 1221 is detachably or fixedly connected to the first end face 11a of the fixed seat 11. In this embodiment, for example, the driving housing 1221 can be welded to the first end face 11a of the fixed seat 11. The above-mentioned driving member 122 is a driving motor (not shown in the figure), and the driving member 122 is common technology for those skilled in the art and is not limited herein.

[0043] Continue to refer to Figures 1 to 6, in some embodiments, the auxiliary positioning component 12 further includes an elastic member 124. The elastic member 124 is sleeved on the positioning member 121. Meanwhile, the elastic member 124 is located between the driving member 122 and the second end 121b of the positioning member 121. For example, one end of the elastic member 124 is located at the end of the driving member 122 away from the first end face 11a, and the other end of the elastic member 124 is located at the second end 121b of the positioning member 121. The elastic member 124 has a certain elasticity. When the driving member 122 works, the driving member 122 drives the positioning member 121 to move in the first direction, and the elastic member 124 is compressed during the movement of the positioning member 121. When the driving member 122 stops working, the elastic member 124 returns to its original state and drives the positioning member 121 to return to its original state. By providing the above elastic member 124 in the auxiliary positioning component 12, the positioning member 121 can be quickly restored to its original state, etc. The above elastic member 124 can be, but is not limited to, a compression spring (not shown in the figure), etc. When the driving member 122 stops working, the elastic member 124 is in an extended state.

[0044] In some embodiments, the positioning member 121 includes a positioning portion 1211 and a positioning shaft 1212. The positioning portion 1211 is connected to the positioning shaft 1212. The size of the positioning portion 1211 is larger than that of the positioning shaft 1212. The elastic member 124 is sleeved on the positioning shaft 1212; meanwhile, the elastic member 124 is located between the positioning portion 1211 and the driving member 122. Through the above positioning member 121, the stability and reliability of the elastic member 124 installed between the driving member 122 and the positioning portion 1211 can be improved, etc. The above positioning portion 1211 is detachably or fixedly connected to the positioning shaft 1212. In this embodiment, for example, the positioning portion 1211 is integrally formed and connected to the positioning shaft 1212. The positioning member 121 can be, but is not limited to, a positioning pin (not shown in the figure). In addition, a limiting structure (not shown in the figure) can be provided at the second end face 11b of the fixed seat 11. The limiting structure can limit one end of the positioning portion 1211 away from the positioning shaft 1212.

[0045] The number of the auxiliary positioning components 12 can be, but is not limited to, two, three, four or more, etc. Each auxiliary positioning component 12 can be, but is not limited to, including the above positioning member 121, driving member 122, switch member 123, elastic member 124, etc. When the suspension rod system auxiliary tool 10 includes more than two groups of auxiliary positioning components 12, the number of the positioning members 121 is at least two, the number of the driving members 122 is at least two, the number of the switch members 123 is at least two, and the number of the elastic members 124 is at least two, etc. Among them, each group of auxiliary positioning components 12 can operate independently or jointly, etc.

[0046] In a specific embodiment, at least two sets of auxiliary positioning components 12 are located outside the periphery of the first fixing hole 112. When the suspension rod system auxiliary tool 10 includes at least two sets of auxiliary positioning components 12, the required auxiliary positioning components 12 can be selected according to the positions of different mounting parts 311 in the subframe 31 and the mounting positions between different swing arms 32, improving the convenience of the suspension rod system auxiliary tool 10.

[0047] Among the above-mentioned at least two sets of auxiliary positioning components 12, the adjacent auxiliary positioning components 12 can be arranged at equal intervals; or, the adjacent auxiliary positioning components 12 among the at least two sets of auxiliary positioning components 12 can be arranged at unequal intervals. The arrangement mode of the at least two sets of auxiliary positioning components 12 can be related to the shape of the fixing seat 11 and the setting position of the first fixing hole 112, which is not limited herein. The fixing seat 11 can be, but is not limited to, circular or square, etc. For example, when the fixing seat 11 is circular, the first fixing hole 112 is located at the center of the fixing seat 11, and at least two sets of auxiliary positioning components 12 can be distributed in a circumferential manner around the first fixing hole 112. When the fixing seat 11 is square, the first fixing hole 112 is located at the center of the fixing seat 11, and at least two sets of auxiliary positioning components 12 can be located on the diagonal line, etc. Of course, when the fixing seat 11 is non-circular, at least two sets of auxiliary positioning components 12 can also be distributed in a circumferential manner outside the first fixing hole 112.

[0048] In this embodiment, the auxiliary positioning component 12 includes three groups. The three groups of auxiliary positioning components 12 are distributed at equal angles in a circumferential manner outside the first fixing hole 112. For example, the central angle between adjacent auxiliary positioning components 12 is 120 degrees. Through the above arrangement mode of the three groups of auxiliary positioning components 12, the convenience of using the suspension rod system auxiliary tool 10 is increased, and the required auxiliary positioning components 12 can be selected according to the positions of different mounting parts 311 in the subframe 31 and the mounting positions between different swing arms 32, etc. In addition, when the three groups of auxiliary positioning components 12 are distributed at equal angles in a circumferential manner outside the first fixing hole 112, the three groups of auxiliary positioning components 12 can be located on the same circular ring of the fixing seat 11.

[0049] Specifically, when the suspension rod system auxiliary tool 10 includes three groups of auxiliary positioning components 12, the required auxiliary positioning components 12 can be selected according to the positions of different mounting parts 311 in the subframe 31 and the mounting positions between different swing arms 32. The switch 123 is turned on at a suitable position, and the switch 123 controls the corresponding positioning member 121 to extend along the first direction and be clamped in the fixing seat 11.

[0050] In some embodiments, when the number of the auxiliary positioning components 12 is two, the fixing seat 11 is provided with at least two second fixing holes 113. The positioning member 121 in each auxiliary positioning component 12 passes through the corresponding second fixing hole 113. In this embodiment, the auxiliary positioning component 12 is three groups, and three second fixing holes 113 are provided on the fixing seat 11.

[0051] Compared with the prior art, in this embodiment, the suspension rod system auxiliary tool includes a fixed seat and an auxiliary positioning component.

The auxiliary positioning component includes a positioning member and a driving member. The positioning member penetrates through the fixed seat. The positioning member includes a first end and a second end arranged opposite to each other. The first end protrudes from the first end face. The second end protrudes from the second end face and is used for plugging into the installation portion in the subframe. The driving member is arranged on the first end face and is connected with the positioning member. The driving member drives the positioning member to move along the first direction.

[0052] Through the cooperation of the above-mentioned fixed seat, the positioning member and the driving member in the auxiliary positioning component, the fixed seat is stably abutted against the installation portion in the subframe. When the local installation position is limited, the positioning and fixing between the nut and the installation portion in the subframe can also be realized, so that the bolt can be tightened and fixed, thereby reducing the phenomenon of the nut rotating with the bolt, and further improving the assembly efficiency and rhythm.

[0053] Continue to refer to Figures 1 to 6 , in some embodiments, the subframe 31 is provided with at least one installation portion 311. The number of the installation portions 311 can be but is not limited to one, two, more than three, etc. A positioning hole 3111 is provided on the installation portion 311 in the subframe 31. The positioning hole 3111 cooperates with the positioning member 121 in the suspension rod system auxiliary tool 10 to achieve the positioning function. In addition, a bolt hole 3112 is provided on the installation portion 311. The bolt hole 3112 is used for the bolt 22 to pass through. The bolt hole 3112 and the positioning hole 3111 are arranged on the same plane of the installation portion 311.

[0054] Specifically, the installation portion 311 has two sub-installation portions 312. Both of the two sub-installation portions 312 are provided with bolt holes 3112 and positioning holes 3111. The number of the above-mentioned positioning holes 3111 and the number of bolt holes 3112 can be determined according to the actual situation and are not limited herein. As in this embodiment, each sub-installation portion 312 is provided with a bolt hole 3112 and a positioning hole 3111.
