Description

Technical Field

[0001] This utility model relates to the field of cooling pipe connection application technology for new energy vehicles, and in particular to a reinforced four-way pressure plate for cooling systems. Background Technology

[0002] The cooling system of new energy vehicles is a key system for ensuring the normal operation of core components such as batteries and motors. It circulates coolant through cooling pipes to maintain the operating temperature of components within a reasonable range. The four-way pressure plate, as a core connecting component for cooling pipes, undertakes important functions of diverting, merging, and steering connections. Its structural rationality and connection reliability directly affect the overall operating efficiency of the cooling system.

[0003] In practical applications, existing four-way pressure plates generally have many technical defects: the connection strength between the connector and the mounting plate is insufficient, and the connection is prone to cracking due to long-term vehicle vibration; the assembly of pipes and connectors lacks effective anti-detachment and limiting structures, which makes the pipes easy to loosen and fall off; some connector designs are not adapted to the pipe layout requirements, which increases the pipe assembly stress and is prone to leakage after long-term use, seriously affecting the stability and safety of the cooling system and failing to meet the high reliability requirements of new energy vehicles for the cooling system. Therefore, this utility model proposes a reinforced four-way pressure plate for the cooling system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a reinforced four-way pressure plate for a cooling system, so as to improve the firmness and stability of pipe connections, enhance structural strength, prevent pipe detachment and leakage, and ensure the stable operation of the cooling system.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a cooling system reinforced four-way pressure plate is provided, including a mounting plate, wherein plug connectors A are symmetrically fixedly connected to the bottom of the mounting plate near the middle position, and the two plug connectors A are integrated with the mounting plate to fix the plug connectors A, thereby ensuring that the external pipes connected to them are firm and stable. The mounting plate has two symmetrically arranged plugs B near the center of its top, and the two plugs B are respectively connected to the two plugs A, so as to connect the pipes connected by plugs A and plugs B.

[0006] The present invention is further configured such that: mounting protrusions are fixedly connected to one of the two corners of the mounting plate, and mounting holes are provided inside the two mounting protrusions.

[0007] Through the above technical solution, the mounting protrusion provides a stable load-bearing structure for the mounting hole. The mounting hole can be used with bolts and other fasteners to fix the mounting plate in the designated installation position of the new energy vehicle cooling system. The diagonal distribution of the installation method makes the mounting plate evenly stressed, avoiding displacement or loosening caused by unbalanced stress after installation, and thus providing a stable foundation support for the connection of connector A and connector B to the external pipeline.

[0008] The present invention is further configured such that: a reinforcing block is integrally provided at the connection between the two plug-in connectors A and the mounting plate, and the reinforcing block is configured in a cross shape.

[0009] Through the above technical solution, the cross-shaped reinforcing block is integrally formed with the mounting plate and the plug connector A. Its cross-shaped distribution structure can disperse the stress at the connection between the plug connector A and the mounting plate from multiple directions, increase the stress-bearing area of ​​the connection, effectively improve the structural strength and fatigue resistance of the connection, avoid the problem of connection breakage caused by vibration, pressure and other factors during long-term use, and extend the service life of the plug connector A.

[0010] The present invention is further configured such that both of the plug connectors A are bent at a 90-degree angle and are fixedly connected to limit blocks at the port positions.

[0011] Through the above technical solution, the plug-in connector A with a 90-degree bend can adapt to the layout requirements of the pipes in the cooling system of new energy vehicles, realize the turning connection of the pipes, and reduce the bending stress during pipe connection; the limiting block at the port can play an axial limiting role for the external pipe inserted into the plug-in connector A, determine the insertion depth of the pipe, avoid the pipe being inserted too shallowly and resulting in a loose connection, and at the same time prevent the pipe from being over-inserted, causing internal channel blockage or pipe damage, thus ensuring the accuracy and effectiveness of the pipe connection.

[0012] The present invention is further configured such that: multiple anti-detachment protrusions are provided equidistantly along the axial direction on the outer wall of both of the plug connectors A near the port.

[0013] With the above technical solution, when the external pipe is sleeved at the port of the plug connector A, multiple anti-detachment protrusions distributed equidistantly along the axial direction can increase the friction between the inner wall of the pipe and the outer wall of the plug connector A, forming multiple anti-detachment barriers, effectively preventing the pipe from falling off the plug connector A under the action of external forces such as vibration and pulling, while enhancing the sealing performance between the pipe and the plug connector A and reducing the risk of leakage.

[0014] The present invention is further configured such that: a reinforcing plate and a reinforcing frame are provided between the two plug-in connectors B and the mounting plate, and the reinforcing plate and the reinforcing frame are sleeved together; and the top of the reinforcing plate and both sides of the two plug-in connectors B are symmetrically fixedly connected with retaining strips.

[0015] Through the above technical solution, the sleeve structure of the reinforcing plate and the reinforcing frame forms a double reinforcement support, which can stabilize the bottom of the plug connector B and disperse the pressure transmitted from the plug connector B to the mounting plate; the symmetrically arranged locking strips on both sides can limit the lateral displacement of the plug connector B from the side, prevent the plug connector B from shifting due to vibration and other factors, and ensure the stability of the connection between the plug connector B and the plug connector A.

[0016] The present invention is further configured such that: the opposing surfaces of the two sets of card strips are fixedly connected with card blocks, and the card blocks respectively engage with the corresponding slots opened on the outer walls of the two plug-in pipe heads B.

[0017] Through the above technical solution, the locking block on the locking strip and the locking groove on the outer wall of the connector B form a precise locking fit. By utilizing the limiting effect of the locking structure, the connector B is firmly fixed to the reinforcing plate, further restricting the axial and radial displacement of the connector B, preventing loosening between the connector B and the mounting plate, and facilitating the installation and disassembly of the connector B, thus improving assembly convenience while ensuring connection stability.

[0018] The beneficial effects of this utility model are as follows: 1. The cooling system reinforced four-way pressure plate proposed in this utility model adopts an integrated structure of plug connector A and mounting plate, and is equipped with reinforcement components such as reinforcement blocks, reinforcement plates, and reinforcement frames, which significantly improves the overall structural strength, effectively disperses the stress of each connection part, avoids the problem of connection breakage, and extends the service life. 2. The cooling system reinforced four-way pressure plate proposed in this utility model ensures the firmness of the pipe connection from multiple aspects such as axial limiting, increased friction, and lateral fixing by setting limiting blocks, anti-detachment protrusion rings, and the engaging structure of the locking block and the locking groove. It effectively prevents pipe detachment and leakage, ensures the stable operation of the cooling system, and is suitable for the use needs of new energy vehicles. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figure 1 As shown, a reinforced four-way pressure plate for a cooling system includes a mounting plate 1. Mounting protrusions are fixedly connected to a pair of corners of the mounting plate 1, and mounting holes 11 are opened inside the two mounting protrusions. The mounting protrusions provide a stable load-bearing structure for the mounting holes 11. The mounting holes 11 can be used with bolts and other fasteners to fix the mounting plate 1 at the designated installation position of the cooling system of the new energy vehicle. By using the diagonal distribution installation method, the mounting plate 1 is subjected to uniform force, avoiding displacement or loosening caused by force imbalance after installation, thereby providing a stable foundation support for the connection of the connector A2 and connector B3 to the external pipe.

[0023] like Figures 2-4 As shown, the bottom of the mounting plate 1 is symmetrically fixed with two connectors A2 near the middle. The two connectors A2 are integrated with the mounting plate 1 to fix the connectors A2, ensuring that the connected external pipes are firm and stable. A reinforcing block 21 is integrally provided at the connection between the two connectors A2 and the mounting plate 1. The reinforcing block 21 is in a cross shape. The cross-shaped reinforcing block 21 is integrally formed with the mounting plate 1 and the connectors A2. Its cross-shaped distribution can disperse the stress at the connection between the connectors A2 and the mounting plate 1 from multiple directions, increase the stress area of ​​the connection, effectively improve the structural strength and fatigue resistance of the connection, avoid the problem of connection breakage caused by vibration, pressure and other factors during long-term use, and extend the service life of the connectors A2. Both connectors A2 are bent at 90 degrees and are fixedly connected to limit blocks 22 at their ports. The 90-degree bends of connectors A2 can adapt to the layout requirements of pipes in the cooling system of new energy vehicles, realize the turning connection of pipes, and reduce the bending stress during pipe connection. The limit blocks 22 at the ports can axially limit the external pipes inserted into connectors A2, define the insertion depth of the pipes, avoid the pipes being inserted too shallowly and resulting in a loose connection, and at the same time prevent the pipes from being inserted too deeply and causing internal channel blockage or pipe damage, thus ensuring the accuracy and effectiveness of the pipe connection. Both plug-in connectors A2 have multiple anti-detachment protrusions 23 equidistantly arranged along the axial direction near the port. When the external pipe is fitted onto the port of plug-in connector A2, the multiple anti-detachment protrusions 23 equidistantly distributed along the axial direction can increase the friction between the inner wall of the pipe and the outer wall of plug-in connector A2, forming multiple anti-detachment barriers. This effectively prevents the pipe from falling off plug-in connector A2 under the action of external forces such as vibration and pulling, while also enhancing the sealing performance between the pipe and plug-in connector A2 and reducing the risk of leakage.

[0024] like Figures 1-5 As shown, two connectors B3 are symmetrically arranged near the center of the top of the mounting plate 1, and the two connectors B3 are respectively connected to the two connectors A2, so that the pipes connected by the connectors A2 and B3 are connected. A reinforcing plate 31 and a reinforcing frame 32 are arranged between the two connectors B3 and the mounting plate 1, and the reinforcing plate 31 and the reinforcing frame 32 are sleeved together. The reinforcing plate 31 has multiple flexible grooves. The top of the reinforcing plate 31 is located between the two connectors B3. Both sides are symmetrically fixed with locking strips 33. The sleeve structure of the reinforcing plate 31 and the reinforcing frame 32 forms a double reinforcement support, which can stabilize the bottom of the plug-in connector B3 and disperse the pressure transmitted from the plug-in connector B3 to the mounting plate 1. The locking strips 33 symmetrically arranged on both sides can limit the lateral displacement of the plug-in connector B3, prevent the plug-in connector B3 from shifting due to vibration and other factors, and ensure the stability of the connection between the plug-in connector B3 and the plug-in connector A2. Both sets of locking strips 33 have locking blocks 331 fixedly connected to their opposite sides. The locking blocks 331 are respectively engaged with the corresponding slots 34 opened on the outer walls of the two connectors B3. The locking blocks 331 on the locking strips 33 and the slots 34 on the outer walls of the connectors B3 form a precise engagement. By utilizing the limiting effect of the engagement structure, the connectors B3 are firmly fixed on the reinforcing plate 31, further restricting the axial and radial displacement of the connectors B3, preventing loosening between the connectors B3 and the mounting plate 1, and facilitating the installation and disassembly of the connectors B3. This ensures connection stability while improving assembly convenience.

[0025] In use, this utility model first uses the mounting holes 11 in the mounting protrusions at the diagonal corners of the mounting plate 1 to fix the mounting plate 1 to the designated position of the new energy vehicle cooling system using bolts; then, the corresponding external cooling pipes are inserted into the ports of connector A2 and connector B3 respectively. The limiting block 22 at the port of connector A2 restricts the insertion depth of the pipe, the anti-detachment protrusion ring 23 enhances the connection between the pipe and the connector, and the locking block 331 on the locking strip 33 engages with the locking groove 34 of connector B3 to ensure that connector B3 is stably fixed; through the communication between connector A2 and connector B3, the smooth connection of different cooling pipes is achieved. Under the action of the reinforcing block 21, the reinforcing plate 31 and the reinforcing frame 32, the stability and fatigue resistance of the overall structure are ensured, and the pipes are effectively prevented from falling off and leaking.
