[0028] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0029] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0030] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0031] In related technologies, a suspension assembly includes two suspension units connected together. Each suspension unit includes a connecting seat, two pressure blocks, and a thrust rod. The pressure blocks and the connecting seat together fix one end of the thrust rod, and the pressure blocks, thrust rod, and connecting seat in the two suspension units are connected together by fasteners.

[0032] However, in the aforementioned suspension assembly, the two pressure blocks in the same suspension unit are asymmetrically arranged, and the line connecting the centers of the connecting holes on the pressure blocks is at a certain angle to the central axis of the pressure blocks. This increases the difficulty of processing the pressure blocks, thereby reducing the assembly efficiency of the entire suspension assembly and consequently reducing the overall vehicle manufacturing efficiency.

[0033] Therefore, this application provides a suspension assembly and a vehicle. By improving the structure of the pressure block in the suspension assembly, the processing cost of the pressure block is reduced, thereby reducing the assembly efficiency of the entire suspension assembly and thus improving the manufacturing efficiency of the whole vehicle.

[0034] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0035] Please combine Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the suspension assembly provided in an embodiment of this application. Figure 2 This is a schematic planar structure diagram of the suspension assembly provided in an embodiment of this application.

[0036] As shown in the figure, this embodiment provides a suspension assembly 10, including two suspension units 1 connected together. The suspension unit 1 includes a connecting seat 11, a pressure block 12, and a thrust rod 13. There are two pressure blocks 12. One end of the thrust rod 13 has two connecting ears 132, which are connected to the axle of the vehicle. The other end of the thrust rod 13 has two connecting posts 131. The two connecting posts 131 are arranged in a one-to-one correspondence with the two pressure blocks 12. A fixing hole 14 is formed between the pressure block 12 and the connecting seat 11 to cooperate with the connecting post 131. The connecting seat 11 has a first central axis l1 extending along the height direction of the vehicle. The two pressure blocks 12 are arranged axially symmetrically about the first central axis l1.

[0037] It should be noted that, in this embodiment, the connecting ear 132 is provided with a fastening hole 1321, and the fastener, such as a screw or other threaded fastener, passing through the fastening hole 1321 can connect the thrust rod 13 to the axle.

[0038] In this embodiment, the two pressure blocks 12 in each suspension unit 1 are symmetrically arranged about the first central axis l1 of the connecting seat. This means that only one mold is needed to process the pressure blocks 12. On the one hand, this reduces the processing difficulty of the four pressure blocks 12, on the other hand, it reduces the processing cost of the four pressure blocks 12, and it also improves the assembly efficiency of the suspension assembly 10 provided in this embodiment.

[0039] Please continue to combine Figure 3 , Figure 3 This is a three-dimensional structural diagram of the connecting seat in the suspension assembly provided in this embodiment. To connect the two suspension units 1 together, the suspension assembly 10 provided in this embodiment also includes a first fastener (not shown in the figure). The pressure block 12 has a first connecting hole 121, the connecting post 131 has a second connecting hole 1311, and the connecting seat 11 has a third connecting hole 111. The first fastener passes sequentially through the first connecting hole 121, the second connecting hole 1311, and the third connecting hole 111 of one suspension unit 1, and through the third connecting hole 111, the second connecting hole 1311, and the first connecting hole 121 of the other suspension unit 1, thus connecting the two suspension units 1 together. It should be noted that the connection of the first fastener not only enables the connection between the two suspension units 1 but also enables the fixation of the end of the thrust rod 13.

[0040] Furthermore, to improve the connection reliability between the two suspension units 1, the suspension assembly 10 provided in this embodiment also includes a second fastener (not shown in the figure). The pressure block 12 has a fourth connecting hole 122 spaced apart from the first connecting hole 121, and the connecting seat 11 has a fifth connecting hole 112 spaced apart from the third connecting hole 111. The second fastener passes sequentially through the fourth connecting hole 122 and the fifth connecting hole 112 of one suspension unit 1, and the fifth connecting hole 112 and the fourth connecting hole 122 of the other suspension unit 1, connecting the two suspension units 1 together. Thus, the connection reliability between the two suspension units 1 is improved through the connection of the second fastener, thereby improving the structural stability of the suspension assembly 10 provided in this embodiment.

[0041] Furthermore, please combine Figure 4 , Figure 4 This is a schematic diagram of the planar structure of the pressure block in the suspension assembly provided in this application embodiment. To further reduce the manufacturing difficulty of the pressure block 12, in some embodiments, the connecting seat 11 has a connecting surface 116 that abuts against the pressure block 12, and the pressure block 12 has a second central axis l2 extending along the height direction of the vehicle. The line connecting the center of the first connecting hole 121 and the center of the fourth connecting hole 122 is the center line l; wherein the orthographic projection of the second central axis l2 on the connecting surface 116 coincides with the orthographic projection of the center line l on the connecting surface 116. In this way, the pressure block 12 itself is an axisymmetric structure, thereby reducing the processing difficulty of the pressure block 12 and further reducing the processing cost of the pressure block 12.

[0042] It is understandable that, in order to improve the connection reliability between the two suspension units 1, the above-mentioned second fasteners can be set to multiple. For a single pressure block 12, multiple second fasteners can be inserted, and the multiple second fasteners are respectively located on opposite sides of the first fastener.

[0043] In other words, for a single pressure block 12, it can have multiple fourth connecting holes 122, and these multiple fourth connecting holes 122 are located on opposite sides of the first connecting hole 121. For example... Figure 1 , Figure 2 and Figure 4 As shown, in a specific embodiment of this example, a pressure block 12 has one first connecting hole 121 and two fourth connecting holes 122. Of course, in other embodiments, the number of first connecting holes 121 and fourth connecting holes 122 on the pressure block 12 can be other numbers. Here, there is no specific limitation on the number of first connecting holes 121 and fourth connecting holes 122.

[0044] Please continue to combine Figure 5 , Figure 5This is a three-dimensional structural diagram of a partial structure of the suspension assembly provided in an embodiment of this application. In some embodiments, the connecting seat 11 includes a body portion 113 and two limiting portions 114. The body portion 113 is used to connect with the vehicle frame, and the two limiting portions 114 are connected to the body. The two limiting portions 114 are correspondingly arranged with two pressure blocks 12, and the limiting portions 114 abut against the pressure blocks 12 to form a fixing hole 14. Specifically, a first fixing hole segment 123 is formed on the pressure block 12, and a second fixing hole segment 1141 is formed on the limiting portion 114. The first fixing hole segment 123 and the second fixing hole segment 1141 together form the fixing hole 14.

[0045] The third connecting hole 111 and the fifth connecting hole 112 both penetrate part of the structure of the limiting part 114 and the main body part 113.

[0046] To facilitate determining the assembly position of the pressure block 12, in some embodiments, an inclined limiting surface 1142 is formed on the limiting portion 114 above the pressure block 12. The pressure block 12 has a stop surface 124 facing the limiting surface 1142, and the stop surface 124 extends horizontally. Specifically, the end of the stop surface 124 stops at the end of the limiting surface 1142. In this way, on the one hand, the assembly position of the pressure block 12 can be determined; on the other hand, by limiting the extension direction of the stop surface 124, compared with related technologies, it is not necessary to set the stop surface 124 as an inclined surface adapted to the limiting surface 1142. This further reduces the processing difficulty and cost of the pressure block 12, and further improves the assembly efficiency of the suspension assembly 10 provided in this embodiment.

[0047] Furthermore, the main body 113 includes a first connecting plate 1131 and a second connecting plate 1132 that are angled to each other and connected together. The first connecting plate 1131 is used to connect to the vehicle frame, and the second connecting plate 1132 is connected to the second connecting plate 1132 in another suspension unit 1.

[0048] Specifically, the first connecting plate 1131 has a plurality of spaced-apart sixth connecting holes 1133, and the second connecting plate 1132 has a plurality of spaced-apart seventh connecting holes 1134. Fasteners, such as screws or other threaded fasteners, passing through the plurality of sixth connecting holes 1133 can connect the connecting seat 11 to the vehicle frame. Two connecting seats 11 can be connected together by passing through the plurality of seventh connecting holes 1134 of one connecting seat 11 and the plurality of seventh connecting holes 1134 of the other connecting seat 11. Thus, a reliable connection between the suspension assembly 10 and the vehicle frame, as well as a reliable connection between the two suspension units 1, can be achieved in this embodiment.

[0049] In some embodiments, the limiting surface 1142 extends obliquely in the vertical direction, and the bottom end of the limiting surface 1142 is closer to the second connecting plate 1132 than the top end of the limiting surface 1142.

[0050] Furthermore, the limiting part 114 includes a first limiting block 1143 and a second limiting block 1144 connected together; the first limiting block 1143 is connected to the first connecting plate 1131, and the second limiting block 1144 is connected to the second connecting plate 1132, forming a clearance space 1145 between the first limiting block 1143 and the second limiting block 1144 to accommodate the pressing block 12; wherein, the limiting surface 1142 is formed on the first limiting block 1143, and the limiting surface 1142 forms the sidewall of the clearance space 1145. Thus, by forming the clearance space 1145, the assembly position of the pressing block 12 can be effectively determined.

[0051] The third connecting hole 111 and the fifth connecting hole 112 pass through the second limiting block 1144 and the second connecting plate 1132, respectively.

[0052] It is understandable that the connecting seat 11 needs to be connected to the vehicle frame, and the connecting seat 11 needs to be connected to the connecting seat 11 in another suspension unit 1. Therefore, the connecting seat 11 needs to have high strength. Therefore, in this embodiment, the connecting seat 11 also includes a reinforcing plate 115, which is connected between the body part 113 and the limiting part 114. In this way, by providing the reinforcing plate 115, the structural strength of the connecting seat 11 can be improved. Thus, when the structural strength of the connecting seat 11 is high, the structural strength of the suspension unit 1 can also be improved, thereby improving the structural strength of the suspension assembly 10 provided in this embodiment, and thus improving the structural stability of the suspension assembly 10 provided in this embodiment.

[0053] Specifically, the reinforcing plate 115 is connected between the second limiting block 1144 and the second connecting plate 1132, and there are two reinforcing plates 115 connected between the second limiting block 1144 and the second connecting plate 1132. Of course, in other embodiments, there may be multiple reinforcing plates 115 connected between the second limiting block 1144 and the second connecting plate 1132. Here, there is no specific limitation on the number of reinforcing plates 115.

[0054] This embodiment also provides a vehicle, including an axle, a frame, and the suspension assembly 10 described in the above embodiments; the axle is connected to the frame, the thrust rod 13 is connected to the axle, and the connecting seat 11 is connected to the frame. The structure of the suspension assembly 10 has been described in detail in the above embodiments and will not be repeated here.

[0055] It should be noted that the vehicle provided in this application embodiment should also include other modules or components that enable the vehicle to move normally. These will not be described in detail here.

[0056] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
