Description

Technical Field

[0001] This utility model relates to the field of vehicle pipeline connection technology, and in particular to a clamp. Background Technology

[0002] In the field of automotive piping connections, the assembly of hoses and connectors has always been a crucial step. However, in practice, several problems often arise, especially when assembling within the confined space of the engine compartment.

[0003] First, when hoses and connectors need to be connected within the confined space of the cabin, operators often cannot effectively hold the clamps and hoses due to space constraints, making the assembly process extremely difficult. In this situation, operators struggle to accurately position and tighten the clamps, thus affecting the quality and efficiency of the assembly.

[0004] Secondly, even with sufficient operating space, traditional clamp designs often suffer from unstable fixation. Because the clamps cannot be effectively secured to the hose, operators must hold the clamp with one hand and tighten it with the other during assembly, increasing operational complexity and reducing production line efficiency. Furthermore, loosening or tilting of the clamps can lead to insecure hose connections, affecting the stability and safety of the entire system. Utility Model Content

[0005] In view of this, the present invention aims to provide a clamp to solve the problem of difficulty in accurately positioning and fastening clamps.

[0006] To achieve the above objectives, the first aspect of this application provides a clamp, including a connector and a clamp body, characterized in that the clamp body is provided with two positioning elements;

[0007] One end of the hoop is fixedly connected to the connector, and the positioning member is positioned on the hoop close to the position where the hoop is fixedly connected to the connector.

[0008] The two positioning components are a first positioning component and a second positioning component. In the pre-tightened state of the clamp, the angle between the straight line pointing from the first positioning component to the center of the clamp body and the straight line pointing from the second positioning component to the center of the clamp body is greater than or equal to 15° and less than or equal to 45°.

[0009] Both positioning elements have a snap-fit ​​area for snapping into the wall of the hose port.

[0010] Optionally, the positioning element includes a base portion and a main body portion;

[0011] The base portion is connected to the hoop body;

[0012] The main body is connected to the end of the base part away from the hoop, and the end of the main body part away from the base part is bent toward the hoop so that the main body part and the base part form the snap-fit ​​area;

[0013] When the clamp is in the pre-tightened state, the wall of the hose port can be inserted into the clamping area so that the clamp is positioned on the hose.

[0014] Optionally, the basic part includes a first part and a second part;

[0015] The first part is fixedly connected to the hoop body;

[0016] The second part is connected to the first part and extends along the width direction of the hoop;

[0017] The main body includes a third part and a fourth part;

[0018] The third part is connected to the end of the second part away from the first part, and the third part and the second part are perpendicular to each other;

[0019] The fourth part is connected to the end of the third part away from the second part, and the fourth part is perpendicular to the third part.

[0020] Optionally, the fourth portion has a spike at one end away from the third portion that faces the snap-fit ​​area.

[0021] Optionally, two spikes are provided, and the fourth part has a slot between the two spikes.

[0022] Optionally, the second part is located on the same plane as the hoop.

[0023] Optionally, the length of the third part is 5mm-7mm.

[0024] Optionally, the distance between the positioning element and the connector is greater than or equal to 10 mm.

[0025] Optionally, the shape formed by the base part and the main body part can be a triangle or a heart shape.

[0026] A second aspect of this application provides a vehicle that includes the clamp provided in the first aspect.

[0027] The beneficial effects of this utility model are:

[0028] 1. Precise positioning and fixing: The positioning component is designed to precisely lock onto the hose end wall, ensuring the hose is accurately positioned on the clamp, reducing the movement or loosening of the hose during installation and use, simplifying installation operations, and avoiding the need for clamp adjustment due to slippage or offset.

[0029] 2. Enhanced fixing effect: The spikes on the positioning piece enhance the fixing effect of the clamp on the hose port, preventing the hose from loosening or falling off during use and improving the stability of the connection.

[0030] 3. Distribute pressure and protect the hose: By having the base of the positioning component and the clamp fit together against the hose wall, the pressure of the clamp on the hose wall can be more effectively distributed, reducing the risk of damage to the hose wall due to excessive local stress.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] like Figure 1 As shown, the first aspect of this application provides a clamp, including a connector 1 and a clamp body 2, characterized in that the clamp body 2 is provided with two positioning elements 3;

[0039] One end of the hoop 2 is fixedly connected to the connector 1, and the positioning piece 3 is positioned on the hoop 2 close to the position where the hoop 2 is fixedly connected to the connector 1.

[0040] The two positioning components 3 are the first positioning component and the second positioning component, respectively. In the pre-tightened state of the clamp, the angle between the straight line of the first positioning component pointing to the center of the clamp body 2 and the straight line of the second positioning component pointing to the center of the clamp body 2 is greater than or equal to 15° and less than or equal to 45°.

[0041] Both positioning elements 3 have a snap-fit ​​area, which is used to snap the hose port wall.

[0042] Connector 1 is a component of the clamp, comprising a housing 11 and a bolt 12. The housing 11 is connected to one end of the clamp body 2. The other end of the clamp body 2 can be inserted through the housing 11, forming a ring that can encircle an object. The clamp body 2 is in a pre-tightened state when inserted into the housing 11. The clamp body 2 has a threaded groove that matches the bolt 12, allowing the threaded groove to engage with the bolt 12. This allows the bolt 12 to control the movement of the clamp body 2 within the housing 11, thereby controlling the size of the ring formed by the clamp body 2 and the housing 11. During clamp pre-tightening, rotating the bolt 12 controls the clamp body 2 to tighten the object to be secured, such as a hose, ensuring the clamp remains stably on the hose and preventing loosening or detachment.

[0043] The positioning element 3 is used to clamp onto objects that require clamping, such as hoses. It has a clamping area that can be set on the positioning element 3 so that the clamping area and the hose wall at the hose port can clamp onto each other, thereby fixing the positioning element 3 and the hose, and thus fixing the clamp that is fixedly connected to the positioning element 3 into the hose.

[0044] The two positioning pieces 3 are positioned close to the fixed connection between the clamp body 2 and the connector 1. This way, when adjusting the clamp or tightening the clamp connector 1 to adjust the clamp body 2, the positioning pieces 3 will not be affected. Furthermore, the included angle between the two positioning pieces 3 is greater than or equal to 15° and less than or equal to 45°, which can increase the overall gripping width of the two positioning pieces 3 without being too dispersed and causing insufficient gripping force.

[0045] By setting two positioning elements 3 and distributing them at a specific angular distance on the clamp 2, the hose can be secured more effectively. This design prevents the hose from moving or falling off due to external forces during use, thereby enhancing the stability of the connection.

[0046] The two positioning elements 3 are distributed at an appropriate angular distance, which can form a more uniform clamping force and subject the hose wall to more even pressure. This helps reduce the risk of hose damage due to excessive local stress and improves the service life of the hose and clamps.

[0047] With the clamp pre-tightened, the angular distance between the two positioning pieces 3 is appropriate, making it easier for operators to insert the hose into the clamp and quickly complete the fixing operation. This reduces installation difficulty and improves work efficiency.

[0048] Furthermore, in an alternative embodiment, the positioning element 3 includes a base portion and a main body portion;

[0049] The base part is connected to hoop 2;

[0050] The main body is connected to the end of the base part away from the hoop 2, and the end of the main body part away from the base part is bent towards the hoop 2 so that the main body part and the base part form a snap-fit ​​area with an opening;

[0051] With the clamp pre-tightened, the hose wall at the end of the hose can be inserted into the clamping area so that the clamp is positioned on the hose.

[0052] The base part of the positioning component 3 is connected to the clamp 2 and extends from the location of the clamp 2 in the width direction of the clamp 2. The main body part of the positioning component 3 connects to the base part at a position away from the clamp 2 and bends back towards the clamp 2, so that the base part and the main body part form a semi-enclosed structure with an opening facing the clamp 2, i.e., the snap-fit ​​area. When the clamp is in the pre-tightened state, the snap-fit ​​area is located inside the ring of the annular clamp 2, thus matching the hose. In this way, when the clamp is adjusted to the pre-tightened state and placed at the end of the hose, the hose end wall can be snapped into the snap-fit ​​area, so that the base part and the main body part of the positioning component 3 clamp the hose wall. After the positioning component 3 is clamped onto the hose wall, moving or shaking the hose body in subsequent operations will not cause the clamp to shift or disengage from the hose body, realizing the positioning and fixation of the clamp on the hose in the pre-tightened state. This prevents the inconvenience caused by the clamp disengaging or shifting during subsequent hose tightening, which would require adjustment.

[0053] like Figure 2 and Figure 3 As shown, further, in an optional embodiment, the base part includes a first part 31 and a second part 32, the first part 31 being fixedly connected to the hoop 2, and the second part 32 being connected to the first part 31 and extending along the width direction of the hoop 2.

[0054] The first part 31 is a component of the base of the positioning element 3. It is fixedly connected to the clamp 2 and fits tightly against the clamp 2. Specifically, it can be fixed to the clamp 2 by stamping or spot welding. The fixed connection of the first part 31 ensures that the positioning element 3 can be stably installed on the clamp 2, providing a solid foundation for subsequent hose positioning.

[0055] The second part 32 connects to the first part 31 and extends along the width of the clamp 2. It further forms the base part of the positioning member 3. The extended design of the second part 32 not only enhances the structural strength of the positioning member 3, but also provides connection points for the subsequent main parts, including the third part 33 and the fourth part 34, so that the entire positioning member 3 can form a snap-fit ​​area with an opening, effectively positioning the pipe wall of the hose port on the clamp.

[0056] The fixed connection between the first part 31 and the clamp 2 ensures the overall stability of the positioning component, allowing it to be securely installed in the desired position. The extended design of the second part 32 further enhances the structural strength of the positioning component, enabling it to withstand greater external forces without easily being damaged. Through the combination of the first part 31 and the second part 32, the positioning component 3 forms a snap-fit ​​area with an opening. This area precisely engages with the hose end wall, ensuring the hose is accurately positioned on the clamp. This precise positioning helps reduce hose movement or loosening during installation and use, thereby improving the stability and reliability of the entire system.

[0057] The main body includes a third part 33 and a fourth part 34. The third part 33 is connected to the end of the second part 32 away from the first part 31, and the third part 33 and the second part 32 are perpendicular to each other. The fourth part 34 is connected to the end of the third part 33 away from the second part 32, and the fourth part 34 and the third part 33 are perpendicular to each other.

[0058] The third part 33 is a component of the main body of the positioning element 3. It connects to the end of the second part 32 furthest from the first part 31 and is perpendicular to the second part 32. This design allows the third part 33 to act as a transition section, connecting the base of the positioning element 3 with the other parts of the main body to form a complete snap-fit ​​area. The connecting function of the third part 33 ensures the overall structural stability and functionality of the positioning element 3. Simultaneously, the vertical design of the third part 33 provides necessary support and guidance for the further connection of the fourth part 34.

[0059] The fourth part 34 is connected to the end of the third part 33 furthest from the second part 32 and is perpendicular to the third part 33. After being supported and guided by the third part 33, the fourth part 34 can be parallel to the second part 32, thus forming a complete snap-fit ​​area. When the hose wall is placed into the snap-fit ​​area, the outer surface of the hose wall contacts the second part 32, and the inner surface of the hose wall contacts the fourth part 34, thereby achieving the clamping and fixing of the hose wall by the positioning element 3.

[0060] The design of Parts 33 and 34 enables Positioning Component 3 to more effectively secure the hose port wall, preventing the hose from loosening or detaching during use. Through the connection and support provided by Parts 33 and 34, the overall structure of Positioning Component 3 is more stable and reliable, capable of withstanding greater external forces and pressure. The stable and reliable fixing effect of Positioning Component 3 makes the assembly process of the hose and connector smoother and more efficient, reducing assembly difficulty and cost. The design of Parts 33 and 34 offers a degree of flexibility, adapting to hose ports of different specifications and sizes, thus improving the versatility and applicability of Positioning Component 3.

[0061] Furthermore, in an alternative embodiment, the fourth portion 34 is provided with a spike 35 facing the snap-fit ​​area at one end away from the third portion 33.

[0062] The fourth part 34, at its end furthest from the third part 33, has a spike 35 facing the locking area. This design enhances the securing effect of the positioning element 3 on the hose port. The presence of the fourth part 34 and its spike 35 allows the positioning element 3 to more effectively clamp the hose port wall, preventing the hose from loosening or falling off during use. Simultaneously, the spike 35 increases the friction between the positioning element 3 and the hose wall, improving the stability and reliability of the fixation. The spike 35 makes the hose positioning within the clamp more stable, maintaining a tight connection between the hose and the clamp even under vibration or shaking conditions, ensuring the reliability and safety of the hose connection.

[0063] Furthermore, in an alternative embodiment, two spikes 35 are provided, and a fourth portion 34 has a slot 36 between the two spikes 35.

[0064] The two spikes 35 further increase the contact points with the hose wall, thereby enhancing the clamping force of the clamp on the hose. This design makes the hose less prone to slippage under external force, improving the stability of the connection. The groove 36 between the two spikes 35 helps optimize stress distribution. When the hose is subjected to pressure or tension, the groove 36 can act as a stress relief point, reducing the risk of deformation and damage to the fourth part 34 and extending the service life of the clamp.

[0065] The groove 36 allows operators to more easily observe the fit between the hose and the clamp during installation and adjustment, ensuring proper clamp placement. Simultaneously, the groove 36 provides some flexibility, allowing the clamp to accommodate hoses of different sizes during installation. By creating the groove 36 between the two spikes 35, material usage can be reduced while maintaining clamp performance, lowering production costs and achieving a dual improvement in environmental and economic benefits.

[0066] Furthermore, in an alternative embodiment, the second part 32 is located on the same plane as the hoop 2.

[0067] That is, after the second part 32 is connected to the first part 31, the portion of the second part 32 extending along the width direction of the clamp 2 is located on the same plane as the clamp 2. In this way, when the clamp 2 is in contact with the wall of the hose, the second part 32 can also be in contact with the wall of the hose at the same time.

[0068] The second part 32 is located on the same plane as the clamp body 2, ensuring that the clamp can more tightly wrap around the hose when it is fitted to the hose wall, reducing gaps caused by shape mismatch, thereby improving the clamp's fixing effect and sealing performance. When the clamp body 2 is tightly fitted to the hose wall, the second part 32 also fits simultaneously, providing an additional support point for the clamp. This design helps increase the stability of the clamp on the hose, preventing it from loosening due to vibration or external forces during use. By having the second part 32 and the clamp body 2 fit together against the hose wall, the pressure of the clamp on the hose wall can be more effectively distributed. This helps reduce the risk of damage to the hose wall due to excessive local stress, thereby extending the service life of the hose and the clamp. This design allows the clamp to more flexibly adapt to hoses of different shapes and sizes. Whether on curved hoses or straight pipes, the clamp maintains a good fit and fixing effect, thus broadening its application scenarios and scope of application.

[0069] When the second part 32 and the clamp body 2 are on the same plane, the overall appearance of the clamp is smoother and more aesthetically pleasing. This helps to improve the overall texture and visual effect of the product, meeting the user's aesthetic needs.

[0070] Furthermore, in an alternative embodiment, the third portion 33 has a length of 5mm-7mm.

[0071] The third part 33 serves as a transitional section connecting the second part 32 and the fourth part 34. Its length is within the range of 5mm-7mm, which ensures the structural stability of the entire positioning component 3, allowing the positioning component 3 to be securely installed on the hoop 2 and effectively forming a snap-fit ​​area.

[0072] The third section 33 within this length range provides sufficient support and guidance for the fourth section 34, allowing the fourth section 34 to be accurately parallel to the second section 32, forming a complete clamping area. This results in better clamping when the hose wall is placed into the clamping area, preventing the hose from loosening or falling off during use.

[0073] By setting the length of the third part 33 within the range of 5mm-7mm, the positioning element 3 can be made flexible enough to adapt to hose ports of different specifications and sizes. This design improves the versatility and applicability of the positioning element 3, enabling the clamp to be widely used in various hose connection applications.

[0074] The length of the third part 33 is moderate; it is neither too long, which would cause unnecessary trouble during manufacturing and installation, nor too short, which would affect the overall structure and function of the positioning component 3. This design makes the manufacturing and installation process of the clamp smoother and more efficient, reducing production costs and installation difficulty.

[0075] Furthermore, in an optional embodiment, the distance between the positioning element 3 and the connector 1 is greater than or equal to 10 mm.

[0076] This ensures sufficient space between the positioning element 3 and the connector 1, preventing unnecessary physical contact or interference and thus avoiding potential friction, collisions, or damage. This arrangement helps maintain the independence and integrity of the two components, ensuring their normal and stable operation. In some cases, the distance between the positioning element 3 and the connector 1 may need to be set according to specific design requirements or standards. A gap greater than or equal to 10 mm may meet these requirements or standards, ensuring product compliance and quality.

[0077] Furthermore, in an alternative embodiment, the shape of the base portion and the main body portion can be a triangle or a heart shape.

[0078] When the base and main body form a triangle, the base can be designed with a right-angled side (e.g., L-shaped), where one right-angled side connects to the clamp 2, and the other right-angled side extends out as one side of the triangle. The main body can then bend back from the extended side of the base at a certain angle (e.g., 90 degrees or less) and connect to another side of the base that is not connected to the clamp, forming an open triangular clamping area. With the clamp pre-tightened, the hose end wall can be inserted into this triangular clamping area, thus achieving the clamp's positioning and fixation of the hose.

[0079] When the base and main body form a heart shape, the base can be designed as a semi-circular structure, with one end connected to the clamp 2 and the other end extending in the width direction of the clamp 2, forming the lower part of the heart. The main body starts from the extended end of the base and curves back in a smooth arc, forming the upper part and sides of the heart. During the bending process, it is necessary to ensure that one end of the main body can bend towards the clamp 2 to form a heart-shaped locking area with an opening. In the pre-tightened state of the clamp, the wall of the hose end can be inserted into this heart-shaped locking area, thereby achieving the positioning and fixation of the hose by the clamp.

[0080] Furthermore, in an optional embodiment, the hoop 2 is also provided with a spring piece 4 and a spring piece protection piece 5, wherein the spring piece 4 is disposed between the spring piece protection piece 5 and the hoop 2, and the two ends of the spring piece protection piece 5 are slidably connected to the hoop 2.

[0081] Spring 4 is used to provide pre-tension force during pre-tensioning to counteract the decrease in clamping force caused by hose deformation. Spring 4 protective plate 5 is used to isolate spring 4 from the hose and prevent spring 4 from cutting the hose.

[0082] A second aspect of this application provides a vehicle that includes the clamp provided in the first aspect.

[0083] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
