Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, specifically to a pipe clamp assembly and a vehicle. Background Technology
[0002] Vehicle air conditioning pipes are used to connect various components of the vehicle's air conditioning system and to deliver refrigerant to these components, allowing the refrigerant to circulate between components such as the compressor, condenser, evaporator, and expansion valve to complete the refrigeration cycle. During vehicle installation, air conditioning pipes are typically secured using multi-hole pipe clamps, which are then fixed to the vehicle frame.
[0003] In related technologies, a pipe clamp includes a pipe clamp body, a flexible disc, and a limiting member. The pipe clamp body has multiple slots with different diameters, and multiple pipes are connected to the multiple slots to be fixed to the pipe clamp body. The flexible disc is located at the bottom of the pipe clamp body and is connected to the pipe clamp body. One end of the limiting member is connected to the flexible disc, and the other end of the limiting member is connected to the vehicle frame, with the side of the flexible disc facing away from the pipe clamp body abutting against the vehicle frame.
[0004] However, the aforementioned technologies have some drawbacks. Specifically, during the use of a vehicle's air conditioning system, the compressor vibrates and transmits the vibration to the interior of the cabin through the air conditioning ducts, reducing the vehicle's noise, vibration, and harshness (NVH) performance and affecting the comfort of passengers. Utility Model Content
[0005] This utility model provides a pipe clamp assembly and a vehicle to solve the problem in related technologies where air conditioning pipes transmit vibrations to the interior of the vehicle cabin, reducing the vehicle's NVH performance.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] On one hand, a pipe clamp assembly is provided, including a pipe clamp body, a bushing, and an elastic element. The pipe clamp body includes a connecting fixing part and a locking part. The fixing part is configured to fix the pipe clamp assembly to a vehicle frame, and the locking part is configured to engage an air conditioning pipe. The fixing part has a first through hole. The bushing includes a sleeve and a gasket. The sleeve is disposed on one side of the gasket and connected to the gasket. The sleeve includes a second through hole that penetrates the gasket; and the sleeve passes through the first through hole. The elastic element is sleeved on the sleeve; the elastic element passes through the first through hole, and one end abuts against the gasket, while the other end is configured to abut against the vehicle frame.
[0008] In some embodiments, the surface of the elastic member near the gasket has a first uneven structure, and / or the surface of the elastic member away from the gasket has a second uneven structure.
[0009] In some embodiments, along the extending direction of the elastic member, the cross-sectional shape of the first concave-convex structure includes any one of serrated, wavy, and rectangular shapes; and / or, along the extending direction of the elastic member, the cross-sectional shape of the second concave-convex structure includes any one of serrated, wavy, and rectangular shapes.
[0010] In some embodiments, the furthest distance between the end of the elastic member away from the gasket and the gasket is greater than the distance between the end of the sleeve away from the gasket and the gasket.
[0011] In some embodiments, the fixing part further includes a retaining plate and a receiving part. The receiving part is disposed on one side of the retaining plate, connected to the retaining plate, and surrounding the retaining plate. The receiving part has a receiving cavity. Along the thickness direction of the retaining plate, the first through hole penetrates the retaining plate and communicates with the receiving cavity.
[0012] In some embodiments, the elastic member has a slot on the side wall near the fixing part, and the slot engages with the card plate.
[0013] In some embodiments, the first through-hole also penetrates a portion of the edge of the card plate along a direction parallel to the plane where the first through-hole is located.
[0014] In some embodiments, the bayonet portion includes a main body and two spring tabs. Along a first direction, one side of the main body is recessed towards the opposite side to form a bayonet. The two spring tabs are disposed at the ends of the bayonet and extend obliquely inward toward the bayonet, respectively.
[0015] In some embodiments, the bayonet portion includes a plurality of bayonets, which are spaced apart along a second direction perpendicular to the first direction. The pipe clamp body further includes a connecting portion and a hollowed-out area, and the fixing portion is connected to the bayonet portion via the connecting portion. The hollowed-out area is disposed between two adjacent bayonets and / or on the connecting portion.
[0016] On the other hand, a vehicle is provided, the vehicle including a pipe clamp assembly, a frame, and fasteners as described in the above embodiments. The frame is fixedly connected to the pipe clamp assembly. The fasteners include a first fastener and a second fastener, the first fastener passing through a second through-hole in the bushing and the frame, and screwed to the second fastener.
[0017] Therefore, the above-mentioned technical features of this utility model have the following beneficial effects:
[0018] (1) An elastic element is fitted onto the sleeve and passes through the first through hole. One end of the elastic element abuts against the gasket, and the other end abuts against the vehicle frame. The first fastener can then pass through the second through hole of the sleeve, and the pipe clamp assembly is fixed to the vehicle frame by adjusting the second fastener. In this case, when the vehicle's air conditioning is in use, the compressor vibrates, causing the air conditioning pipes and pipe clamp assembly to vibrate as well. Since one end of the elastic element abuts against the gasket and the other end abuts against the vehicle frame, and the elastic element is located between the pipe clamp body and the bushing, the elastic element will buffer the vibration from multiple directions, improve the problem of the air conditioning pipes transmitting vibration to the vehicle frame and then to the interior of the cabin, improve the vibration damping of the pipe clamp assembly, and thus improve the NVH performance of the vehicle and the comfort of the passengers.
[0019] (2) When the elastic element is subjected to vibration, the concave and convex structures in the first and / or second concave and convex structures can deform and bend relatively independently. Compared with a smooth elastic element, the first and / or second concave and convex structures provide more deformation directions and space, enabling the elastic element to generate more compression when subjected to force, thereby further improving the damping performance of the pipe clamp assembly and improving the NVH performance of the vehicle and the comfort of the passengers to a greater extent.
[0020] (3) Along the extension direction of the elastic element, the cross-sectional shape of the first concave-convex structure includes any one of sawtooth, wavy, and rectangular shapes. And / or, along the extension direction of the elastic element, the cross-sectional shape of the second concave-convex structure includes any one of sawtooth, wavy, and rectangular shapes. In this case, compared with a smooth surface elastic element, the first concave-convex structure and / or the second concave-convex structure provide more deformation directions and space, enabling the elastic element to generate more compression when under force, thereby further improving the damping performance of the pipe clamp assembly and improving the NVH performance of the vehicle and the comfort of the passengers to a greater extent.
[0021] (4) The furthest distance between the end of the elastic element furthest from the gasket and the gasket is greater than the distance between the end of the sleeve furthest from the gasket and the gasket. In this case, the elastic element can be guaranteed to have a certain amount of compression in the length direction, thereby further improving the shock absorption effect of the elastic element. In addition, the bushing can support and limit the elastic element, preventing damage when the elastic element is subjected to excessive force.
[0022] (5) Some elastic elements can be located in the accommodating cavity, which serves to limit and protect the elastic elements.
[0023] (6) During the installation and fixing of the pipe clamp assembly to the vehicle frame, the engagement of the slot and the clamping plate of the elastic element prevents the elastic element from moving within the first through hole, thereby improving assembly efficiency. Furthermore, after the pipe clamp assembly is installed and fixed to the vehicle frame, the engagement of the slot and the clamping plate of the elastic element ensures that the position of the elastic element remains relatively fixed when it plays a role in buffering vibration, reducing the impact of vibration on the stability of the pipe clamp assembly.
[0024] (7) When the elastic element is passed through the first through hole and the slot is engaged with the card plate, the elastic element can be installed into the first through hole through the through hole firstly to prevent the card plate from damaging the elastic element when the elastic element is installed perpendicular to the first through hole, and to improve assembly efficiency.
[0025] (8) The bayonet is used to clamp the air conditioning pipe. Two spring clips are set at the end of the bayonet to limit the air conditioning pipe and prevent the air conditioning pipe from coming out of the bayonet.
[0026] (9) Setting a hollow area can reduce the weight of the pipe clamp body, thereby helping to improve the vehicle body's lightweight design. In addition, setting a hollow area can also reduce the production cost of the pipe clamp body.

Detailed Implementation
[0036] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0037] Figure 1 The diagram shown is a structural schematic of a vehicle provided in some embodiments of this application; Figure 2 The diagram shown is a structural schematic of a pipe clamp assembly provided in some embodiments of this application.
[0038] like Figure 1 and Figure 2 As shown, this application embodiment provides a vehicle 1000, which can be any power-driven vehicle such as a fuel vehicle or a new energy vehicle. The vehicle 1000 includes a pipe clamp assembly 100, a frame 200, fasteners 300, and an air conditioning pipe 400. The pipe clamp assembly 100 is used to clamp the air conditioning pipe 400 and is fixedly connected to the frame 200 by the fasteners 300. The fasteners 300 include a first fastener 310 and a second fastener 320. For example, the first fastener 310 can be a bolt, and the second fastener 320 can be a nut.
[0039] Figure 3 The diagram shown is a structural schematic of an elastic element provided in some embodiments of this application. Figure 4 The diagram shown is a structural schematic of a bushing provided in some embodiments of this application; Figure 5 The diagram shown is a structural schematic of a pipe clamp body provided in some embodiments of this application; Figure 6 The image shown is a side view of a pipe clamp body provided in some embodiments of this application.
[0040] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the pipe clamp assembly 100 includes a pipe clamp body 10, a bushing 20, and an elastic member 30. The pipe clamp body 10 includes a connecting fixing part 11 and a locking part 12. The fixing part 11 is configured to fix the pipe clamp assembly 100 to the vehicle frame 200, and the locking part 12 is configured to engage the air conditioning pipe 400. The fixing part 11 has a first through hole 111. The bushing 20 includes a sleeve 21 and a gasket 22. The sleeve 21 is disposed on one side of the gasket 22 and connected to the gasket 22. The sleeve 21 includes a second through hole 211 that penetrates the gasket 22, and the sleeve 21 passes through the first through hole 111. The elastic member 30 is sleeved on the sleeve 21, passes through the first through hole 111, and has one end abutting against the gasket 22, while the other end is configured to abut against the vehicle frame 200.
[0041] As described above, the elastic element 30 is sleeved on the sleeve 21 and passes through the first through hole 111. One end of the elastic element 30 abuts against the gasket 22, and the other end abuts against the frame 200. The first fastener 310 can then pass through the second through hole 211 of the sleeve 21, and the pipe clamp assembly 100 is fixed to the frame 200 by adjusting the second fastener 320. In this case, when the vehicle's air conditioning is in use, the compressor vibrates, causing the air conditioning pipe 400 and the pipe clamp assembly 100 to also vibrate. Since one end of the elastic element 30 abuts against the gasket 22 and the other end abuts against the frame 200, and the elastic element 30 is located between the pipe clamp body 10 and the bushing 20, the elastic element 30 will buffer the vibration from multiple directions, improving the problem of the air conditioning pipe 400 transmitting vibration to the frame 200 and then to the interior of the vehicle cabin, improving the shock absorption of the pipe clamp assembly 100, and thus improving the vehicle's NVH performance and the comfort of the passengers.
[0042] For example, the material of the elastic element 30 includes rubber, which gives the elastic element 30 good elasticity, thereby enabling the elastic element 30 to effectively absorb and buffer vibration energy and reduce the transmission of vibration. For example, the material of the elastic element 30 includes at least one of natural rubber and nitrile rubber.
[0043] In some embodiments, such as Figure 2 and Figure 6 As shown, the shape of the first through hole 111 includes either an oval or a racetrack shape. In this way, when the pipe clamp assembly 100 is installed and fixed to the frame 200, the bushing 20 and the elastic element 30 can move and adjust their installation positions within the first through hole 111, so that the first fastener 310 can be aligned with the mounting hole on the frame 200, thereby improving assembly efficiency.
[0044] In some embodiments, such as Figure 2 , Figure 3 and Figure 4As shown, the surface of the elastic member 30 near the gasket 22 has a first concave-convex structure 31, and / or the surface of the elastic member 30 away from the gasket 22 has a second concave-convex structure 32. When the elastic member 30 is subjected to vibration, the concave-convex structures in the first concave-convex structure 31 and / or the second concave-convex structure 32 can deform and bend relatively independently. Compared to a smooth-surfaced elastic member, the first concave-convex structure 31 and / or the second concave-convex structure 32 provide more deformation directions and space, enabling the elastic member 30 to generate more compression when subjected to force, thereby further improving the vibration damping performance of the pipe clamp assembly 100 and significantly enhancing the NVH performance of the vehicle and the comfort of the occupants.
[0045] For example, such as Figure 3 As shown, along the extending direction of the elastic member 30, the cross-sectional shape of the first concave-convex structure 31 includes any one of sawtooth, wavy, and rectangular shapes. And / or, along the extending direction of the elastic member 30, the cross-sectional shape of the second concave-convex structure 32 includes any one of sawtooth, wavy, and rectangular shapes. In this case, compared to a smooth-surfaced elastic member, the first and / or second concave-convex structures provide more deformation directions and space, enabling the elastic member to generate more compression under stress, thereby further improving the damping performance of the clamp assembly and significantly enhancing the vehicle's NVH performance and passenger comfort.
[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the furthest distance L1 between the end of the elastic element 30 furthest from the gasket 22 and the gasket 22 is greater than the distance L2 between the end of the sleeve 21 furthest from the gasket 22 and the gasket 22. This ensures that the elastic element 30 has a certain amount of compression in the length direction, thereby further improving the shock absorption effect of the elastic element 30. In addition, the bushing 20 can support and limit the elastic element 30, preventing damage when the elastic element 30 is subjected to excessive force.
[0047] In some embodiments, such as Figure 2 and Figure 5 As shown, the fixing part 11 also includes a retaining plate 112 and a receiving part 113. The receiving part 113 is disposed on one side of the retaining plate, connected to the retaining plate, and surrounding the retaining plate 112. The receiving part 113 has a receiving cavity 1131. Along the thickness direction of the retaining plate 112, a first through hole 111 penetrates the retaining plate 112 and communicates with the receiving cavity 1131. In this way, part of the elastic element 30 can be located within the receiving cavity 1131, and the receiving cavity 1131 serves to limit and protect the elastic element 30.
[0048] In some embodiments, such as Figure 2 , Figure 3 and Figure 5As shown, the elastic member 30 has a slot 33 on its side wall near the fixing part 11, and the slot 33 engages with the clamping plate 112. In this case, during the installation and fixing of the pipe clamp assembly 100 to the frame 200, the engagement of the slot 33 of the elastic member 30 with the clamping plate 112 prevents the elastic member 30 from moving within the first through hole 111, thereby improving assembly efficiency. Furthermore, after the pipe clamp assembly 100 is installed and fixed to the frame 200, the engagement of the slot 33 of the elastic member 30 with the clamping plate 112 ensures that the position of the elastic member 30 remains relatively fixed when it plays a role in buffering vibration, reducing the impact of vibration on the stability of the pipe clamp assembly 100.
[0049] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, along a direction parallel to the plane where the first through hole 111 is located, the first through hole 111 also penetrates part of the edge of the clamping plate 112. In this way, when the elastic member 30 is passed through the first through hole 111 and the clamping groove 33 is engaged with the clamping plate 112, the elastic member 30 can be installed into the first through hole 111 through the through hole first, preventing the clamping plate 112 from damaging the elastic member 30 when it is installed perpendicular to the first through hole 111, and improving assembly efficiency.
[0050] In some embodiments, such as Figure 2 and Figure 5 As shown, the bayonet portion 12 includes a main body 121 and two spring tabs 122. Along the first direction X, one side of the main body 121 is recessed towards the opposite side to form a bayonet 1211. The two spring tabs 122 are disposed at the ends of the bayonet 1211 and extend obliquely inward toward the bayonet 1211. The first direction X is perpendicular to the length direction of the bayonet portion 12. In this case, the bayonet 1211 is used to engage the air conditioning pipe 400, and the two spring tabs 122, disposed at the ends of the bayonet 1211, are used to limit the air conditioning pipe 400 and prevent it from dislodging from the bayonet 1211.
[0051] It should be noted that the two spring pieces 122 form acute angles with the ends of the bayonet 1211 to serve as a limiting mechanism.
[0052] In some examples, the material of the two spring clips 122 includes polyhexamethylene adipamide 66 (PA66). This material gives the spring clips 122 good toughness and strength, so that when the air conditioning pipe 400 is installed in or removed from the bayonet 1211, the two spring clips 122 can be repeatedly bent without being damaged, thereby improving the durability and reliability of the pipe clamp assembly 100.
[0053] In some embodiments, the pipe clamp body 10 is integrally formed. In this case, the pipe clamp body 10 can be formed by injection molding, allowing for the production of a large number of products from a single mold, improving production efficiency and reducing molding difficulty. Furthermore, the integrally formed pipe clamp body 10 can improve stability and reliability.
[0054] For example, the material of the pipe clamp body 10 includes polyhexamethylene adipamide 66 (PA66 for short), which has less rigidity than metal pipe clamps, resulting in better shock absorption of the pipe clamp body 10.
[0055] In some embodiments, such as Figure 2 and Figure 5 As shown, the bayonet portion 12 includes a plurality of bayonets 1211, which are arranged at intervals along a second direction Y, perpendicular to the first direction X. The pipe clamp body 10 also includes a connecting portion 13 and a hollowed-out area 14. The fixing portion 11 is connected to the bayonet portion 12 via the connecting portion 13. The hollowed-out area 14 is disposed between two adjacent bayonets 1211, and / or on the connecting portion 13. In this case, providing the hollowed-out area 14 can reduce the weight of the pipe clamp body 10, thereby contributing to the lightweighting of the vehicle body. Furthermore, providing the hollowed-out area 14 can also reduce the production cost of the pipe clamp body 10.
[0056] In some examples, such as Figure 2 and Figure 5 As shown, multiple bayonets 1211 can be bayonets with different hole sizes to adapt to air conditioning pipes 400 of different specifications, thereby improving the practicality of the pipe clamp assembly 100.
[0057] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope 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.
