Technical Field

[0002] The present application belongs to the technical field of spring pads, and in particular relates to a cold-bonded spring pad for automobiles. Background Art

[0003] In a car's suspension system, a spring washer is typically placed between the spring and the car body, or between the spring and the swing arm. This washer prevents a rigid connection between the spring and the car body or swing arm, acting as a buffer to prevent friction and impact noise from the spring during driving, thus impacting ride comfort. With the development of new energy vehicles, their weight is increasing, and since the engines are replaced, noise requirements are relatively higher, so improvements are urgently needed.

[0004] Application Contents

[0005] In view of the problems mentioned in the background technology, the purpose of this application is to provide a cold-bonded spring pad for automobiles to solve the problems mentioned in the background technology.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A cold-bonded spring pad for an automobile includes a mounting body for mounting a spring, and is characterized in that a top surface of the mounting body is provided with a receiving groove for accommodating the spring and a mounting opening for mounting the spring in the receiving groove, the receiving groove and the mounting opening are communicated, and an adhesive layer for bonding the spring is provided in the receiving groove.

[0008] As a preferred technical solution, the accommodating groove is a spiral groove.

[0009] As a preferred technical solution, the receiving groove and the mounting opening are coaxial with the mounting body, and the sum of the central angles of the receiving groove and the mounting opening is 360°.

[0010] As a preferred technical solution, the central angle corresponding to the installation opening is an acute angle.

[0011] As a preferred technical solution, one end of the accommodating groove has a stopper for closing the accommodating groove.

[0013] As a preferred technical solution, a first groove is formed on the side wall of the accommodating groove near the center of the mounting body, and a portion of the adhesive layer is filled into the first groove.

[0014] As a preferred technical solution, a second groove is formed on a side wall of the accommodating groove away from the center of the mounting body, and a portion of the adhesive layer is filled into the second groove.

[0015] As a preferred technical solution, multiple groups of protrusions are installed on the accommodating groove.

[0016] As a preferred technical solution, the thickness of the adhesive layer is not less than the height of the protrusion.

[0017] In summary, this application has the following beneficial effects:

[0018] The adhesive layer is spread over the entire receiving groove, and the bottom end of the spring is rotated into the receiving groove from the installation opening until one end of the spring contacts the stop portion. The stop portion limits the spring to prevent the spring from sliding sideways, and the boss is clamped to the bottom end of the spring to prevent the spring from falling off during transportation. An adhesive layer is stored between the bosses on the receiving groove. The adhesive layer makes the connection between the mounting body and the spring more secure, and the adhesive layer makes the mounting body and the spring fit completely, which can effectively prevent foreign objects from entering during vehicle driving and eliminate the risk of abnormal noise caused by mutual friction here. The bottom end of the spring squeezes the adhesive layer into the first groove and the second groove to form a hook shape, which further stabilizes the spring; not only that, the adhesive layer also plays a role in buffering and shock absorption, and can also protect the spring, which can extend the service life of the spring pad. At the same time, when the mounting body is damaged during use, the adhesive layer can be removed and the mounting body can be replaced without destroying the entire spring.

[0027] Example 1

[0028] 1 to 6 , a cold-bonded spring pad for an automobile described in this embodiment includes a mounting body 100 and a spring 200. The top surface of the mounting body 100 is provided with a receiving groove 120 for accommodating the spring 200 and a mounting opening 210 for mounting the spring 200 in the receiving groove 120. The receiving groove 120 and the mounting opening 210 are both coaxial with the mounting body 100, and the sum of the central angles corresponding to the mounting opening 210 and the receiving groove 120 is 360°. An adhesive layer 220 for bonding the spring 200 is contained in the receiving groove 120.

[0029] Preferably, the adhesive layer 220 is glue.

[0030] Preferably, the receiving groove 120 is a spiral groove.

[0031] Preferably, the central angle corresponding to the mounting opening 210 is an acute angle.

[0032] Preferably, one end of the accommodating groove 120 has a stopping portion 140 for closing the accommodating groove 120 , and the other end of the accommodating groove 120 is communicated with the mounting opening 210 .

[0033] A boss 110 is provided at the central top of the mounting body 100 , and the receiving groove 120 and the mounting opening 210 both surround the boss 110 . Three bosses 170 for limiting the spring 200 are provided at equal intervals on the outer wall of the boss 110 in the receiving groove 100 .

[0034] A first groove 150 is defined on a sidewall of the receiving groove 120 near the center of the mounting body 100 , and the adhesive layer 220 fills the first groove 150 .

[0035] A second groove 160 is defined on a sidewall of the receiving groove 120 away from the center of the mounting body 100 , and the adhesive layer 220 fills the second groove 160 .

[0036] A plurality of groups of protrusions 250 are installed on the receiving groove 120 at equal intervals.

[0037] Preferably, the top of the protrusion 250 is smooth.

[0038] The thickness of the adhesive layer 220 is not less than the height of the protrusion 250 .

[0039] An assembly hole 130 is defined in the middle of the boss 110 along the axial direction and passes through the boss 110 and the mounting body 100 .

[0040] The assembly hole 130 includes an upper hole section 131 and a lower hole section 132 that are connected. The diameter of the lower hole section 132 gradually increases from an end close to the upper hole section 131 to an end away from the upper hole section 132 .

[0041] A positioning groove 180 is defined at the bottom of the mounting body 100 located at the mounting opening 210 .

[0042] An anti-error identification boss 190 is provided at the bottom end of the mounting body 100 located at the mounting opening 210 .

[0043] The adhesive layer 210 is spread over the receiving groove 120, and the bottom end of the spring 200 is rotated into the receiving groove 120 from the installation opening 210 until one end of the spring 200 contacts the stopper 140. The stopper 140 limits the spring 200 to prevent the spring 200 from sliding sideways. The boss 170 is engaged with the bottom end of the spring 200 to prevent the spring 200 from falling off during transportation. The adhesive layer 210 is stored between the bosses 250 on the receiving groove 120. The adhesive layer 210 makes the connection between the mounting body and the spring 200 more secure, and the adhesive layer 210 makes the mounting body 100 and the spring 200 more secure. The spring 200 fits perfectly, which can effectively prevent foreign objects from entering during the driving of the vehicle and eliminate the risk of abnormal noise caused by mutual friction. The bottom end of the spring 200 squeezes the adhesive layer 210 into the first groove 150 and the second groove 160 to form a hook shape, which further stabilizes the spring 200. Not only that, the adhesive layer 210 also plays a role in buffering and shock absorption, and can also protect the spring 200, which can extend the service life of the spring pad. At the same time, when the installation body is damaged during use, the adhesive layer 220 can be removed and the installation body can be replaced without destroying the entire spring 200.

[0044] The positioning groove 180 can avoid the problem of position and angle errors during the assembly process, and the anti-error identification boss 190 can avoid the problem of product misassembly.

[0045] The lower hole section 132 cooperates with the spring disc of the vehicle body. The lower hole section 132 forms a guiding function during assembly, which facilitates assembly and has a limiting effect when the spring washer and the spring disc cooperate.
