[0016] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0017] like Figure 1 - Figure 3 As shown, the buffer block according to the embodiment of the present application includes a rubber member 1, a threaded member 2 and an adjusting nut 3. The threaded member 2 includes a connecting portion 21 and a screw portion 22 connected in sequence, the connecting portion 21 is connected to the rubber member 1, and at least part of the screw portion 22 protrudes outside the rubber member 1. The adjusting nut 3 is threadably matched with the screw portion 22, the adjusting nut 3 is spaced apart from the rubber member 1, and is used to abut against the counterpart.

[0018] According to the embodiment of the present application, the buffer block can be installed on the opponent by threading the screw portion 22 of the threaded member 2 with the threaded hole on the opponent, and by rotating the buffer block, the position of the rubber member 1 in the buffer block relative to the opponent can be adjusted. Moreover, after the buffer block is installed at the set position of the opponent through the screw portion 22, the adjusting nut 3 is also rotated to make the adjusting nut 3 abut against the opponent. At this time, the friction between the adjusting nut 3 and the opponent realizes the self-locking of the screw portion 22 relative to the opponent, and the screw portion 22 is less likely to rotate relative to the opponent by mistake. Therefore, the installation reliability of the buffer block on the opponent is higher, and it is less likely to loosen by itself and cause position changes or even fall off.

[0019] It should be noted that the counterpart is a component on the vehicle, specifically including a sheet metal 4 and a projection welding nut 5 connected to the sheet metal 4. When the buffer block is installed on the counterpart, the adjusting nut 3 is first threadedly engaged with the screw portion 22, and then the screw portion 22 passes through the mounting hole on the sheet metal 4, and then threadedly engaged with the threaded hole of the projection welding nut 5. After the screw portion 22 is rotated into place, the adjusting nut 3 is rotated to abut against the side of the sheet metal 4 facing away from the projection welding nut 5.

[0020] In some embodiments of the present application, Figure 1 As shown, the rubber member 1 covers the connecting portion 21 and a portion of the screw portion 22 .

[0021] That is, the connecting portion 21 and part of the screw portion 22 are hidden in the rubber member 1, and the buffer block is in contact with external parts through the rubber member 1, thereby achieving the buffering noise reduction or limiting noise reduction function of the buffer block.

[0022] Specifically, the rubber component 1 can be injection molded on the connecting portion 21 and part of the screw portion 22 through a vulcanization process, or the rubber component 1 is pre-injection molded, and a mounting cavity for interference fit or snap fit between the connecting portion 21 and part of the screw portion 22 is formed on the rubber component 1. At the same time, the connecting portion 21 and part of the screw portion 22 can also be bonded to the inner surface of the mounting cavity by bonding, thereby effectively ensuring the connection strength and connection reliability of the rubber component 1 and the threaded component 2.

[0023] In some embodiments of the present application, Figure 1 As shown, the rubber member 1 has a first end face 11 away from the adjusting nut 3, and the connecting portion 21 has a second end face 211 away from the adjusting nut 3. The minimum distance between the first end face 11 and the second end face 211 is d1, wherein 3mm≤d1≤4mm, or 1.5mm≤d1≤2mm.

[0024] The portion of the rubber component 1 located between the first end face 11 of the rubber component 1 and the second end face 211 of the connecting portion 21 is the main portion that collides and deforms with external parts. When making a buffer block, the hardness of the buffer block can be changed by adjusting the distance between the first end face 11 of the rubber component 1 and the second end face 211 of the connecting portion 21. The larger the distance, the smaller the hardness of the above-mentioned portion. Therefore, when using the same hardness rubber material to make the rubber component 1, setting 3mm≤d1≤4mm is equivalent to a hardness between 55HRE and 50HRE, which can play a good buffering and noise reduction function. Setting 1.5mm≤d1≤2mm is equivalent to a hardness between 75HRC and 70HRC, which can play a good limiting and noise reduction function.

[0025] In other words, only one type of hardness rubber material is needed to produce a buffer block with buffering and limiting functions respectively. The buffer block is easy to process, the various production materials are easy to purchase, the material cost is low, and the difficulty of production control is low.

[0026] Specifically, the first end surface 11 and the second end surface 211 are parallel to each other, and the distance between them can be 1.5 mm, 1.75 mm, 2 mm, 3 mm, 3.5 mm and 4 mm.

[0027] In some embodiments of the present application, Figure 1 As shown, the minimum distance between the outer circumference of the rubber member 1 and the outer circumference of the connecting portion 21 is d2, wherein d2≥1.5 mm.

[0028] This effectively ensures the radial connection strength between the rubber component 1 and the connection portion 21 , and effectively prevents the rubber component 1 from being too thin and easily damaged, thereby exposing the connection portion 21 .

[0029] Specifically, the outer contours of the rubber member 1 and the connecting portion 21 are both cylindrical, the outer circumferential surfaces of the rubber member 1 and the connecting portion 21 are both circular surfaces and coaxial, and the distance between the two outer circumferential surfaces can be 1.5 mm, 1.7 mm, and 1.9 mm.

[0030] In some embodiments of the present application, Figure 1 As shown, the connecting portion 21 has a third end surface 212 connected to the outer circumferential surface of the screw portion 22 , and the third end surface 212 is provided with a plurality of protrusions 23 extending along the axial direction of the screw portion 22 . The plurality of protrusions 23 are arranged at intervals along the circumference of the screw portion 22 , and the rubber member 1 covers the protrusions 23 .

[0031] At least part of the rubber member 1 is located between any two adjacent protrusions 23. The cooperation between this part and the protrusion 23 realizes the relative fixation of the rubber member 1 and the threaded member 2 in the circumferential direction, effectively preventing the rubber member 1 from rotating relative to the threaded member 2 and affecting the functional reliability of the buffer block.

[0032] Specifically, the outer circumferential surface of the connecting portion 21 is a circular surface, and there may be three protrusions 23, which are arranged at equal intervals along the circumference of the screw portion 22, and the outer surface of each protrusion 23 is connected to the outer circumferential surface of the connecting portion 21, and the protrusions 23 and the screw portion 22 are arranged at intervals in the radial direction of the screw portion 22.

[0033] In some embodiments of the present application, Figure 1 As shown, the rubber member 1 further has a fourth end face 12 opposite to the adjusting nut 3 along the axial direction of the screw portion 22, and the minimum distance between the fourth end face 12 and the third end face 212 is d3, wherein d3≥2mm. And / or, the axial dimension of the protrusion 23 in the screw portion 22 is d4, wherein d3>d4≥0.8mm.

[0034] The setting of the minimum distance between the fourth end face 12 and the third end face 212 being not less than 2 mm effectively improves the axial connection strength between the rubber component 1 and the threaded component 2, and effectively avoids damage to the portion of the rubber component 1 located between the third end face 212 and the fourth end face 12, which may cause the rubber component 1 to axially disengage from the threaded component 2.

[0035] At the same time, the axial dimension of the protrusion 23 on the screw portion 22 is set to be no less than 0.8 mm, which further ensures the reliability of the circumferential limit of the protrusion 23 and the rubber member 1, and the circumferential connection strength between the rubber member 1 and the threaded member 2 is higher.

[0036] Specifically, the third end face 212 and the fourth end face 12 are parallel to each other, and the distance d3 therebetween can be 2 mm, 2.3 mm, or 2.6 mm. The axial dimension d4 of the protrusion 23 in the screw portion 22 can be 0.8 mm, 1 mm, or 1.2 mm.

[0037] In some embodiments of the present application, the threaded member 2 is a bolt, so that the threaded member 2 is easy to purchase, the purchase cost is low, and the overall cost of the buffer block is lower.

[0038] And / or, the cross-sectional outer contour of the connecting portion 21 is a polygon or an irregular shape. In this case, when the rubber member 1 covers the connecting portion 21, it is not necessary to provide the protrusion 23, and the relative fixation of the rubber member 1 and the threaded member 2 in the circumferential direction can also be effectively ensured.

[0039] For example, the outer contour of the cross section of the connecting portion 21 may be a regular hexagon, that is, the threaded member 2 is an external hexagonal bolt.

[0040] In some embodiments of the present application, the diameter of the screw portion 22 is d5, wherein 3 mm ≤ d5 ≤ 8 mm.

[0041] Therefore, the diameter of the mounting hole on the sheet metal 4 that is clearance-matched with the screw portion 22 is also between 3 mm and 8 mm, and the sheet metal 4 abuts against the adjusting nut 3 rather than the rubber part 1 with a larger cross-sectional area. Therefore, there is no need to set a larger plane space on the sheet metal 4 for processing the mounting hole, and the installation space of the buffer block on the sheet metal 4 is small, and there are many installation application scenarios.

[0042] Specifically, the diameter of the screw portion 22 can be 3mm, 6mm and 8mm. The length of the threaded portion in the screw portion 22 is greater than or equal to 10mm. After the screw portion 22 cooperates with the projection welding nut 5 on the counterpart, the length of the portion of the screw portion 22 protruding from the projection welding nut 5 is greater than or equal to 2mm, so as to leave sufficient installation margin for the buffer block.

[0043] In some embodiments of the present application, the outer contour of the cross section of the rubber member 1 is circular, and the outer diameter of the rubber member 1 is d6, where d6 ≥ 17 mm.

[0044] That is, the outer contour of the rubber component 1 is cylindrical, and the rubber component 1 with the above dimensions can have sufficient structural strength, and when hit by a part, it can withstand a greater impact without deformation or damage.

[0045] Specifically, the outer diameter d6 of the rubber member 1 may be 17 mm, 18 mm, or 19 mm.

[0046] The vehicle according to an embodiment of the present application includes a buffer block as described in any of the above embodiments.

[0047] The technical advantages of the vehicle according to the embodiment of the present application are the same as the technical advantages of the buffer block in the above-mentioned embodiment, which will not be repeated here.

[0048] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
