[0027] like Figures 1 to 3 As shown, this embodiment proposes a vibration isolation device for engine pipelines, including a pipe clamp body 1 and a fixing member 2. The pipe clamp body 1 has a slot 12, and the fixing member 2 is built into the pipe clamp body 1. Specifically, the pipe clamp body 1 has a receiving cavity, and the fixing member 2 is built into the receiving cavity. The receiving cavity also has a vibration isolation member 3, which wraps around the fixing member 2. In this way, by providing a slot 12 on the pipeline body 1, the engine pipeline can be clamped through the slot 12; by providing the fixing member 2, it can be used with bolts to fix the pipe clamp body 1 to the front bulkhead of the vehicle; by providing a receiving groove on the pipe clamp body 1, the fixing member 2 can be received therein, and by providing a vibration isolation member 3 between the receiving groove and the fixing member 2, the vibration isolation member 3 can absorb the energy transmitted by engine vibration, effectively avoiding noise in the cabin caused by engine vibration and improving driving comfort.

[0028] Preferably, the vibration isolator 3 is a vibration-damping rubber component. By using a rubber material, the vibration isolator 3 has a better vibration absorption effect.

[0029] Further, please refer to Figure 2 and Figure 3 As shown, the vibration isolation component 3 includes a first vibration isolation pad 31 and a second vibration isolation pad 32. The first vibration isolation pad 31 and the second vibration isolation pad 32 are sleeved on the fixing component 2, and the first vibration isolation pad 31 and the second vibration isolation pad 32 are detachably installed in the receiving cavity. In this way, when the first vibration isolation pad 31 or the second vibration isolation pad 32 is damaged, it can be partially replaced according to actual needs, avoiding the need to replace the entire vibration isolation component 3 due to partial damage, thus reducing material costs.

[0030] Further, please refer to Figure 2As shown, the first vibration isolation pad 31 and / or the second vibration isolation pad 32 are provided with a boss 33, which can abut against the end face of the pipe clamp body 1. Preferably, in this embodiment, both the first vibration isolation pad 31 and the second vibration isolation pad 32 are provided with a boss 33. By providing the boss 33, the contact area between the first vibration isolation pad 31 and the second vibration isolation pad 32 and the pipe clamp body 1 is increased, which can achieve better vibration absorption and reduce noise in the cockpit.

[0031] Further, please refer to Figure 1 As shown, the first vibration isolation pad 31 and / or the second vibration isolation pad 32 are provided with steps 34, and the fixing member 2 is provided with a locking platform 21, which abuts against the steps 34. Preferably, in this embodiment, both the first vibration isolation pad 31 and the second vibration isolation pad 32 are provided with steps 34. In this way, the fixing member 2 can abut against the steps 34 on the first vibration isolation pad 31 or the steps 34 on the second vibration isolation pad 32, depending on actual needs, thus meeting the diverse needs of users.

[0032] Preferably, the card holder 21 has a triangular cross-section. Of course, in this embodiment, depending on the actual situation and specific needs, the cross-section of the card holder 21 can also be rectangular, rhomboid, L-shaped, etc., and is not limited here.

[0033] Further, please refer to Figure 2 As shown, there are two mounting brackets 21, which are respectively disposed on opposite sides of the fixing member 2. The first vibration isolation pad 31 and / or the second vibration isolation pad 32 are respectively provided with two steps 34 that cooperate with the two mounting brackets 21. By setting two brackets, it is ensured that both sides of the fixing member 2 abut against the first vibration isolation pad 31 and / or the second vibration isolation pad 32, thereby enhancing the installation stability of the first vibration isolation pad 31 or the second vibration isolation pad 32.

[0034] Preferably, the fastener is made of plastic. By making the fastener 2 a plastic part, the rigid connection between the fastener 2 and the bolt is avoided, which helps to reduce the transmission of noise to the cab and further improves driving comfort.

[0035] Further, please refer to Figure 3 As shown, the fastener 2 has a through hole 22, and the through hole 22 has an internal thread 23. The internal thread 23 is connected with a bolt, so that the pipe clamp body 1 can be fixed to the front panel of the car.

[0036] Further, please refer to Figure 3As shown, the cross-section of the vibration isolator 3 is in the shape of a Chinese character 'hui'. The distance between the accommodation cavity and the fixing member 2 is less than or equal to the thickness of the vibration isolator 3. In this way, the vibration isolator 3 can be firmly clamped by the cooperation of the inner wall of the accommodation cavity and the fixing member 2, which is beneficial for the vibration isolator 3 to absorb better.

[0037] Further, please refer to Figure 1 As shown, clamping platforms 11 are provided on the opposite sides of the pipe clamp body 1, and clamping grooves 12 are respectively provided on each clamping platform 11. By providing two clamping grooves 12, two engine pipelines can be clamped. Of course, according to the actual situation, multiple clamping platforms 11 can also be provided, and multiple clamping grooves 12 can be opened on the multiple clamping platforms 11 to clamp more pipelines, achieving the effect of integration and space saving.

[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
