[0002] Due to the application scenarios of electric scroll compressors, their external space is limited by the vehicle's installation space, which in turn restricts the layout of the controller. When the vehicle is subjected to a frontal collision, the compression of the front compartment will directly impact the high-voltage connectors and wiring harness connections on the compressor controller side, posing a risk of short-term high-voltage exposure and further endangering the safety of the occupants.

[0003] Therefore, this utility model provides a vehicle scroll compressor with a connector anti-collision structure. Utility Model Content

[0004] To address the problems in the existing technology, the purpose of this utility model is to provide a vehicle scroll compressor with a connector anti-collision structure, which overcomes the difficulties of the existing technology. It can provide anti-collision protection for connectors through the compressor's own shell structure, which not only reduces the space required for anti-collision structures in the vehicle, but also improves the protection of high-voltage wiring harnesses in the event of a collision.

[0020] Preferably, when a 2WN external force is applied to the top of the anti-collision baffle, the deformation of the anti-collision baffle is less than 7mm.

[0021] Preferably, it further includes a bumper guard, which is integrally formed with the low-voltage platform and protrudes from the side of the low-voltage harness interface facing the impact direction.

Figure 2 This is a second-view perspective perspective view of a vehicle scroll compressor with a connector anti-collision structure according to this utility model. Figure 3 This is a third-person perspective view of a vehicle scroll compressor with a connector anti-collision structure according to the present invention. Figure 4 yes Figure 3 A magnified view of a portion of the image. Figure 3 and Figure 4 In the diagram, the x-axis represents the direction of the car's front, i.e., the direction of impact; the y-axis represents the direction of gravity. For example... Figures 1 to 4As shown, the automotive scroll compressor with connector-based anti-collision structure of this utility model includes: a compressor housing 1, a controller housing 2, and an anti-collision baffle 3. The controller housing 2 is connected to the bottom of the compressor housing 1. The controller housing 2 includes a low-pressure platform 23 and a high-pressure platform 24 protruding from the low-pressure platform 23. The low-pressure platform 23 is provided with a low-pressure wiring harness interface 21, and the high-pressure platform 24 is provided with a high-pressure wiring harness interface 22. The high-pressure platform 24 is located on the side of the low-pressure platform 23 away from the impact direction. The anti-collision baffle 3 is integrally formed with the high-pressure platform 24. The anti-collision baffle 3 protrudes from the side of the high-pressure wiring harness interface 22 facing the impact direction. The ratio of the top thickness to the bottom thickness of the anti-collision baffle 3 is between 1 / 2 and 2 / 3. With the center of the high-pressure wiring harness interface 22 as the center, the coverage angle of the two sides of the anti-collision baffle 3 is 60° to 120°. The low-voltage wiring harness interface 21 in this invention is used to connect low-voltage cables, mainly providing control signals and data signals between the compressor and the vehicle's infotainment system. The high-voltage wiring harness interface 22 is used to connect high-voltage cables, mainly providing power to drive the compressor. If the high-voltage wiring harness interface 22 is damaged, it can easily lead to the high-voltage cable breaking, posing a risk of short-term high-voltage exposure, which could endanger the user. This invention is a vehicle scroll compressor with connector anti-collision function. A special protective structure is added to the controller housing to achieve connector impact protection. The biggest feature of this design is that, without affecting the overall vehicle layout boundaries, the compressor's own structural optimization achieves a connector anti-collision structure, protecting the compressor connector from high-voltage exposure after impact breakage, thus mitigating the risk to passenger safety.

[0053] In a preferred embodiment, the height H of the anti-collision baffle 3 protruding from the high-pressure platform 24 is in the range of 25≤H<30; the top thickness of the anti-collision baffle 3 is W1, and the range of W1 is 10≤W1≤15; the bottom thickness of the anti-collision baffle 3 is W2, and the range of W2 is 15≤W2≤20, but not limited thereto.

[0054] In a preferred embodiment, the height H of the anti-collision baffle 3 protruding from the high-pressure platform 24 is in the range of 30≤H≤40; the top thickness of the anti-collision baffle 3 is W1, and the range of W1 is 7≤W1≤10; the bottom thickness of the anti-collision baffle 3 is W2, and the range of W2 is 10.5≤W2≤20, but not limited thereto.

[0055] In a preferred embodiment, the minimum gap between the boundary of the anti-collision baffle 3 and the boundary of the high-voltage wiring harness interface 22 is W3, where W3 > 15 mm, but is not limited thereto.

[0056] In a preferred embodiment, the anti-collision baffle 3 includes a first folded edge 31 and a second folded edge 32. The first folded edge 31 and the second folded edge 32 intersect to form an intersection 33. The first projection range of the intersection 33 in the impact direction overlaps with the second projection range of the high-voltage wire harness interface 22 in the impact direction, but is not limited thereto.

[0057] In a preferred embodiment, when a 2WN external force is applied to the top of the anti-collision baffle 3, the deformation of the anti-collision baffle 3 is less than 7mm, but is not limited thereto.

[0058] In one alternative embodiment, a bumper (not shown) is also included, which is integrally formed with the low-voltage platform 23. The bumper protrudes from the side of the low-voltage harness interface 21 facing the impact direction to provide additional protection, but is not limited thereto.

[0059] The specific implementation of this utility model is as follows:

[0060] like Figures 1 to 4As shown, the automotive scroll compressor with connector-based anti-collision structure of this utility model includes: a compressor housing 1, a controller housing 2, and an anti-collision baffle 3. The controller housing 2 is connected to the bottom of the compressor housing 1. The controller housing 2 includes a low-pressure platform 23 and a high-pressure platform 24 protruding from the low-pressure platform 23. The low-pressure platform 23 is provided with a low-pressure wiring harness interface 21, and the high-pressure platform 24 is provided with a high-pressure wiring harness interface 22. The high-pressure platform 24 is located on the side of the low-pressure platform 23 away from the impact direction. The anti-collision baffle 3 is integrally formed with the high-pressure platform 24. The anti-collision baffle 3 protrudes from the side of the high-pressure wiring harness interface 22 facing the impact direction. The ratio of the top thickness to the bottom thickness of the anti-collision baffle 3 is between 1 / 2 and 2 / 3. With the center of the high-pressure wiring harness interface 22 as the center, the coverage angle of the two sides of the anti-collision baffle 3 is 60° to 120°. The anti-collision baffle 3 includes a first folded edge 31 and a second folded edge 32. The first folded edge 31 and the second folded edge 32 intersect to form a junction 33. The first projection range of the junction 33 in the impact direction overlaps with the second projection range of the high-voltage wire harness interface 22 in the impact direction. Since the deformation resistance of the junction 33 is significantly higher than that of the first folded edge 31 and the second folded edge 32, it strengthens the protection of the high-voltage wire harness interface 22 in the impact direction and prevents deformation after impact. Due to the above structure, when a 2WN external force is applied to the top of the anti-collision baffle 3, the deformation of the anti-collision baffle 3 is less than 7mm. The minimum gap between the boundary of the anti-collision baffle 3 and the boundary of the high-voltage wire harness interface 22 is W3, where W3 > 15mm, thus meeting the space requirements of the connector for the fitting.

[0061] The crash barrier 3 protrudes from the edge of the high-voltage platform 24 near the low-voltage platform 23, with a height H of 25mm to 40mm protruding from the high-voltage platform 24. The crash barrier 3 is a protrusion with a gradually narrowing cross-section from bottom to top. The height H of the crash barrier 3 protruding from the high-voltage platform 24 is 25 ≤ H < 30mm. The top thickness of the crash barrier 3 is W1, with a range of 10 ≤ W1 ≤ 15mm. The bottom thickness of the crash barrier 3 is W2, with a range of 15 ≤ W2 ≤ 20mm. Alternatively, the height H of the crash barrier 3 protruding from the high-voltage platform 24 is 30 ≤ H ≤ 40mm; the top thickness of the crash barrier 3 is W1, with a range of 7 ≤ W1 ≤ 10mm; and the bottom thickness of the crash barrier 3 is W2, with a range of 10.5 ≤ W2 ≤ 20mm.

[0062] This invention aims to provide collision protection for connectors through the compressor's own housing structure without altering the overall vehicle layout. This not only reduces the space required for a collision protection structure within the vehicle but also utilizes the inherent strength of the compressor housing material to more effectively protect the connectors. Extending the compressor's controller housing to design the connector collision protection structure aligns with current front compartment layout trends. Furthermore, the strength of the compressor housing material and the stability of the casting structure contribute to the effectiveness of the collision protection structure. When the vehicle is subjected to a frontal impact, the compression of the front compartment layout directly impacts the high-voltage connectors and wiring harness connections on the compressor controller side, posing a risk of short-term high-voltage exposure and potentially endangering the safety of the occupants.

[0063] This invention reduces the risk of instantaneous disconnection in high-voltage connectors by designing a simulated stop structure in the impact direction. Verified through simulation results and vehicle collision tests, the specific requirements for the stop size and shape are as follows: the stop is located on the side of the connector closest to the vehicle's impact direction, with the center of the connector mounting point as the center, and the coverage angle α of the stop edge ranging from 60° to 120°.

[0064] The relationship between the stop block height H and other dimensions of the stop block is shown in the table below: (unit: mm)

[0065] 25≤H＜30 15≤W2≤20 10≤W1≤15 30≤H≤40 10.5≤W2≤20 7≤W1≤10

[0066] The minimum gap W3 between the stop block boundary and the connector boundary of this utility model is greater than 15mm, thereby meeting the connector's space requirements for the mating plug.

[0067] This invention eliminates the need for additional space in the vehicle for anti-collision structures, allowing implementation directly at the compressor end. The strength of the compressor housing material effectively reduces housing deformation after impact (deformation less than 7mm after a 2WN load on the top of the stop). This invention has wide applicability; existing compressors can all incorporate this structure to address the impact direction.

[0068] In summary, the purpose of this utility model is to provide a vehicle scroll compressor with a connector anti-collision structure, which can protect the connector through the compressor's own shell structure without changing the overall vehicle layout. This not only reduces the space required for the anti-collision structure in the vehicle, but also utilizes the strength of the compressor shell material itself to more effectively protect the connector, thereby improving the protection of the high-voltage wiring harness in the event of a collision.

[0069] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
