Description

Technical Field

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

[0002] The drive motor controller is usually located directly in front of the front electric drive system. When the vehicle is involved in a frontal collision, the front electric drive system is easily compressed by the collision in a short period of time, making it difficult for the front electric drive system to perform the high voltage cut-off action, which can lead to a short circuit and fire.

Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] In the description of this utility model, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the number of indicated technical features, or the sequential relationship between indicated technical features.

[0024] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0025] It should be noted that the drive motor controller is generally located directly in front of the front electric drive system. When the vehicle is involved in a frontal collision, the front electric drive system is easily compressed by the collision in a short period of time, making it difficult for the front electric drive system to perform the high voltage cut-off action, which may lead to a short circuit and fire.

[0026] Reference Figures 1 to 5As shown, the first aspect of this utility model provides a protective bracket 10 for connecting a motor 20. When connected to the motor 20, the protective bracket 10 can cover at least a portion of the motor controller 30 connected to the motor 20. The protective bracket 10 includes a connecting portion 100 and a collision portion 200. The connecting portion 100 is used to connect the motor 20. The collision portion 200 is connected to the connecting portion 100 and protrudes from the connecting portion 100 in a direction away from the motor controller 30. The collision portion 200 is configured such that when the collision portion 200 is subjected to an external force, the collision portion 200 transmits the external force to the connecting portion 100, dispersing the external force to each connecting portion 100, thereby delaying the collision time between the protective bracket 10 and the motor controller 30, providing sufficient operating time for the high-voltage power-off operation of the motor controller 30, reducing the probability of short-circuit fire accidents, and improving safety performance.

[0027] It should be noted that the motor 20 is installed in the front compartment (also known as the engine compartment) of the vehicle. Along the direction from the front to the rear of the vehicle, the protective bracket 10, the motor controller 30, and the motor 20 are arranged in sequence. When the front of the vehicle collides, the front of the vehicle collapses and absorbs energy, causing the protective bracket 10 to be subjected to force before the motor controller 30, thereby protecting the motor controller 30 and delaying the impact time of the motor controller 30. This gives the motor controller 30 more time to perform high-voltage power-off operation, thereby reducing the occurrence of short-circuit fire accidents and improving safety performance.

[0028] Specifically, the motor 20 is generally directly or indirectly connected to the vehicle frame, and the motor 20 can be connected using high-strength connectors, making the connection between the motor 20 and the frame more reliable. In addition, the motor 20 includes a motor housing, which is also made of high-strength materials and has a reinforced structure. Therefore, the overall structural strength of the motor 20 is high. The protective bracket 10 includes a connecting part 100 and a collision part 200. The connecting part 100 is connected to the motor housing and supported by the motor housing, giving the protective bracket 10 higher support strength. In the event of a collision, the protective bracket 10 receives a higher support force, resulting in better protection. At the same time, the collision part 200 protrudes from the connecting part 100 in a direction away from the motor controller 30. That is, the collision part 200 will be impacted before the connecting part 100. After the collision, the collision part 200 will distribute the impact force to the connecting part 100, and the connecting part 100 will bear the main impact force. The connecting part 100 will then transfer the impact force to the motor housing, thus realizing the transfer of impact force. This allows the protective bracket 10 to withstand higher impact forces and has a better protection effect.

[0029] It is understandable that because the structural strength of the protective bracket 10 is increased, resulting in a structural strength far exceeding the design strength, the thickness of the protective bracket 10 is optimized to reduce structural costs. This slightly reduces the structural strength of the protective bracket 10 while still meeting the design strength standards. The reduced thickness also reduces the weight of the protective bracket 10, thereby lowering its manufacturing cost and contributing to vehicle lightweighting to some extent. In this embodiment, the minimum thickness of the protective bracket 10 is approximately 4mm, and the average thickness is approximately 5mm to 7mm, while the average thickness of ordinary brackets is generally 8mm or more.

[0030] In this embodiment, the protective bracket 10 includes multiple connecting parts 100. For example, the protective bracket 10 covers one corner of the motor controller 30 and includes three connecting parts 100. Of course, the protective bracket 10 can also cover the entire motor controller 30 or other parts, and the protective bracket 10 can also include two or four or more connecting parts 100. Each connecting part 100 includes a connecting plate and a connecting post. The connecting plate is connected to the collision part 200. One end of the connecting post is connected to the connecting plate, and the other end of the connecting post extends from the front to the rear of the vehicle. The connecting post also has a connecting through hole that communicates with the connecting plate in the direction from the front to the rear of the vehicle. The motor housing has a locking hole, and a connecting bolt passes through the connecting through hole and is locked into the locking hole, thus connecting the connecting part 100 to the motor 20. In another embodiment, the connecting part 100 includes a connecting plate part connected to the collision part 200. The connecting plate part has a connecting through hole along the direction from the front to the rear of the vehicle. The motor housing has a mounting post. The end of the mounting post away from the motor housing has a mounting hole. The connecting plate part abuts against the end of the mounting post away from the motor housing, and the connecting through hole is aligned with the mounting hole. The connecting bolt passes through the connecting through hole and is locked inside the mounting hole, thereby realizing the connection between the connecting part 100 and the motor 20.

[0031] The connecting part 100 also includes a plurality of reinforcing ribs, which are connected between the connecting plate part and the connecting column part. The plurality of reinforcing ribs are distributed sequentially along the circumference of the connecting column part, and the distribution of the plurality of reinforcing ribs can be uniform or non-uniform.

[0032] Reference Figure 3 and Figure 5 As shown, in some specific embodiments of this utility model, the collision part 200 includes a first part 210 and a second part 220. The first part 210 is arranged along a first direction, and the second part 220 is arranged along a second direction. The first direction intersects with the second direction, and both the first part 210 and the second part 220 are connected to the connecting part 100.

[0033] It is worth understanding that by transmitting the collision force in different directions through the first part 210 and the second part 220, and by transmitting the collision force in different directions to the area where the connecting part 100 is located, the collision force in each direction can be concentrated in the area where the connecting part 100 is located and transmitted to the motor housing through the connecting part 100, thereby further improving the structural strength of the protective bracket 10.

[0034] In this embodiment, the first direction is perpendicular to the second direction. The first portion 210 and the second portion 220 intersect and are perpendicular to each other, forming a cross shape. That is, the first portion 210 and the second portion 220 have overlapping areas. Taking the overlapping area as the origin and the first portion 210 and the second portion 220 as coordinate axes, four quadrant regions are formed between the first portion 210 and the second portion 220. The protective bracket 10 includes three connecting portions 100, which are respectively located in three of the four quadrant regions. Specifically, when the first portion 210 is impacted by a collision force, the first portion 210 will transmit the collision force along the second direction. The collision force received by the first portion 210 will be transmitted along the second direction towards each quadrant region, and the collision force received by the second portion 220 will be transmitted along the first direction towards each quadrant region, thereby realizing the transmission of the collision force to the region where the connecting portion 100 is located.

[0035] In other embodiments, the first direction may also be set at a certain angle to the second direction; the distribution of the first part 210 and the second part 220 intersecting and perpendicular to each other also includes: the first part 210 and the second part 220 being distributed in a "T" shape, forming two or three quadrant regions between the first part 210 and the second part 220; or the first part 210 and the second part 220 being distributed in an "L" shape, forming one or two quadrant regions between the first part 210 and the second part 220; when the protective bracket 10 includes four connecting parts 100, the four connecting parts 100 may be respectively located within the four quadrant regions.

[0036] In addition, the collision part 200 may also include a first part 210, which is disposed along a first direction or a second direction. The first part 210 directly forms two quadrant regions, and the connecting part 100 is disposed in at least one of the two quadrant regions.

[0037] Reference Figure 3 and Figure 5 As shown, in some specific embodiments of this utility model, the first portion 210 protrudes from the second portion 220 in a direction away from the motor controller 30; that is, the second portion 220 protrudes from the second portion 220. For example... Figure 3As shown by the black unidirectional arrow, the path for transmitting impact force in the protective bracket 10 includes: first section 210 – connecting section 100 and first section 210 – second section 220 – connecting section 100. The external force received by the protective bracket 10 is transmitted through multiple transmission paths and concentrated at the connecting section 100, further improving the structural strength of the protective bracket 10. As another embodiment, the protruding side of the first section 210 relative to the connecting section 100 and the protruding side of the second section 220 relative to the connecting section 100 can be flush with each other.

[0038] In some specific embodiments of this utility model, the thickness of the collision part 200 and the thickness of the connecting part 100 increase along the direction from the collision part 200 to the connecting part 100.

[0039] It is understandable that when the collision part 200 is impacted, it is more prone to deformation. The collision part 200 transmits the impact force through deformation. Since the thickness of the connecting part 100 is greater than that of the collision part 200, the connecting part 100 can withstand a greater impact force, resulting in better support for the collision part 200 and thus improving the overall structural strength of the protective bracket 10. In this embodiment, the thickness of both the first portion 210 and the connecting part 100 increases along the direction from the first portion 210 to the connecting part 100, and the thickness of both the second portion 220 and the connecting part 100 also increases along the direction from the second portion 220 to the connecting part 100.

[0040] Reference Figure 4 As shown, in some specific embodiments of this utility model, the protective bracket 10 further includes an inner groove wall 300; the inner groove wall 300 is connected to the side of the collision part 200 facing the motor controller 30; and / or, the connecting part 100 faces the side of the motor controller 30; the inner groove wall 300 at least surrounds the collision part 200 to form a protective groove 101, the protective groove 101 being used to cover the high voltage connecting part 32 of the motor controller 30.

[0041] It should be noted that the high-voltage connection part 32 of the motor controller 30 refers to the part where the motor controller 30 connects to the high-voltage wiring harness. The high-voltage wiring harness mainly supplies high-voltage electricity and has high energy. Therefore, a short circuit in the high-voltage connection part 32 can easily cause a fire. The protective groove 101 formed by the inner groove wall 300 and the collision part 200 means that the inner groove wall 300 and the collision part 200 together form a groove body, and the protective groove 101 is located within the groove body. In this embodiment, the inner groove wall 300 constitutes the side wall of the groove body, the collision part 200 constitutes the bottom wall of the groove body, and the inner groove wall 300 has an opening that connects the protective groove 101 to the outside. The high-voltage wiring harness from the outside passes through the opening and is electrically connected to the high-voltage connection part 32 inside the protective groove 101.

[0042] Specifically, the collision part 200 includes a first surface and a second surface opposite to each other, the first surface being opposite to the motor controller 30, the inner groove wall 300 being disposed on the first surface and extending toward the motor controller 30; and / or, the connecting part 100 includes a third surface and a fourth surface opposite to each other, the third surface being opposite to the motor controller 30, the inner groove wall 300 being disposed on the third surface and extending toward the motor controller 30.

[0043] It is understandable that the inner groove wall 300 and the collision part 200 together form a protective groove 101. The protective groove 101 covers the high-voltage connection part 32 of the motor controller 30 along the direction from the front to the rear of the vehicle, so that the protective groove 101 protects the high-voltage connection part 32 of the motor controller 30, effectively reducing the possibility of short circuit and fire caused by collision. At the same time, the inner groove wall 300 also plays a certain supporting role. When the inner groove wall 300 is connected to the collision part 200 and the connection part 100, the inner groove wall 300 can increase the structural strength of the collision part 200 and the connection part 100, thereby improving the overall structural strength of the protective bracket 10.

[0044] In this embodiment, the inner tank wall 300 includes a first partition wall 310 disposed along a first direction and a second partition wall 320 disposed along a second direction. The first partition wall 310 is disposed in the transition region between the first portion 210 and the connecting portion 100, and the second partition wall 320 is disposed in the transition region between the second portion 220 and the connecting portion 100, thereby increasing the structural strength of all transition regions and thus increasing the reliability of the impact force transmission from the impact portion 200 to the connecting portion 100. Furthermore, the second partition wall 320 is connected to the first portion 210 along the second direction, and the inner tank wall 300 can increase the structural strength of the first portion 210, enabling the first portion 210 to withstand higher impact forces.

[0045] Reference Figure 4 As shown, in some specific embodiments of this utility model, the protective bracket 10 further includes a first reinforcing part 400; the first reinforcing part 400 is connected between the collision part 200 and the inner groove wall 300; and / or, the first reinforcing part 400 is connected between the connecting part 100 and the inner groove wall 300.

[0046] In this embodiment, the first reinforcing part 400 is connected between the collision part 200 and the inner tank wall 300 to strengthen the connection between the collision part 200 and the inner tank wall 300, thereby improving the structural strength of the connection. The first reinforcing part 400 is also connected between the connecting part 100 and the inner tank wall 300 to strengthen the connection between the connecting part 100 and the inner tank wall 300, thereby improving the structural strength of the connection, resulting in higher structural strength for the protective bracket 10. The first reinforcing part 400 is a reinforcing rib structure.

[0047] Reference Figure 4As shown, in some specific embodiments of this utility model, the protective bracket 10 further includes an outer groove wall 500 and a second reinforcing part 600; the outer groove wall 500 is connected to the side of the collision part 200 facing the motor controller 30, and the outer groove wall 500, the inner groove wall 300, and the collision part 200 together form a reinforcing chamber 102; and / or, the outer groove wall 500 is connected to the side of the connecting part 100 facing the motor controller 30, and the outer groove wall 500, the inner groove wall 300, and the connecting part 100 together form a reinforcing chamber 102; the second reinforcing part 600 is disposed within the reinforcing chamber 102.

[0048] In this embodiment, the outer groove wall 500 is connected to both the first surface of the collision part 200 and the third surface of the connecting part 100. The outer groove wall 500 can further strengthen the structural strength of the collision part 200 and the connecting part 100. At the same time, the outer groove wall 500 and the inner groove wall 300 are connected by the second reinforcing part 600 so that the outer groove wall 500 and the inner groove wall 300 support each other, further enhancing the overall structural strength of the protective bracket 10.

[0049] Reference Figure 4 As shown, in some specific embodiments of this utility model, the protective bracket 10 further includes a third reinforcing part 700. The third reinforcing part 700 is disposed in the collision part 200. The third reinforcing part 700 strengthens the structural strength of the collision part 200, enabling the collision part 200 to withstand greater collision forces, thereby improving the reliability of the force transmission of the protective bracket 10. In this embodiment, the third reinforcing part 700 is disposed within the first portion 210 to strengthen the first portion 210 that is the first to come into contact with the collision force, thereby improving the reliability of the protective bracket 10.

[0050] Reference Figure 1 and Figure 2 As shown, the second aspect of this utility model proposes a vehicle, which includes a frame, a motor 20, a motor controller 30, and a protective bracket 10 as described in the first aspect embodiment. The motor 20 is connected to the frame; the motor controller 30 is connected to the motor 20; and the protective bracket 10 is connected to the motor 20 and covers at least a portion of the motor controller 30. The protective bracket 10, the motor controller 30, and the motor 20 are arranged sequentially along the collision direction of the frame. The vehicle adopts the protective bracket 10 of the first aspect embodiment, which improves the vehicle's safety performance while reducing manufacturing costs.

[0051] It should be noted that the collision direction of the vehicle frame refers to the following: when the motor 20 is installed in the front compartment, the collision direction is from the front to the rear of the vehicle; when the motor 20 is installed in the rear compartment, the collision direction is from the rear to the front of the vehicle. In this embodiment, the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0052] Reference Figure 2 As shown, in some specific embodiments of this utility model, the motor controller 30 includes a main body 31 and a high-voltage connection part 32. The high-voltage connection part 32 is connected to the main body 31 and is used to connect the high-voltage wiring harness. The protective bracket 10 is covered by the high-voltage connection part 32.

[0053] It should be noted that the motor controller 30 includes a housing and an electrical control unit, with the electrical control unit housed within the housing. The surface of the housing is the same as the surface of the main body 31. Because the electrical control unit needs to be electrically connected to electrical components such as the battery and motor 20, a connector is provided on the surface of the housing for the high-voltage wiring harness to be snapped into place. When the high-voltage wiring harness is snapped into the connector, it is electrically connected to the electrical control unit. However, the connection point between the high-voltage wiring harness and the motor controller 30 is therefore exposed outside the housing. In the event of a collision, this connection point is easily subjected to impact and compression, potentially leading to a short circuit and fire.

[0054] It is understandable that by covering the high-voltage connection part 32 with the protective bracket 10, the protective bracket 10 mainly protects the location of the high-voltage connection part 32, thereby reducing the occurrence of short circuit and fire accidents of the high-voltage connection part 32. In addition, the protective bracket 10 needs to cover a smaller area, making the protective bracket 10 itself smaller, which is more conducive to saving the cost of the protective bracket 10 and can achieve vehicle weight reduction.

[0055] In this embodiment, the main body 31 is basically rectangular, the high voltage connection part 32 is disposed on the surface of the main body 31 away from the motor 20 and is located at one corner of the main body 31, and the protective bracket 10 is covered in the area where the high voltage connection part 32 is located and is spaced apart from the high voltage connection part 32 to protect the high voltage connection part 32.

[0056] Reference Figure 2As shown, in some specific embodiments of this utility model, the high-voltage connection portion 32 protrudes from the surface of the main body portion 31, and the protective bracket 10 has a protective groove 101. The protective groove 101 covers the high-voltage connection portion 32 to provide more comprehensive protection for the protruding high-voltage connection portion 32, thereby reducing the probability of short circuit and fire of the high-voltage connection portion 32. As another embodiment, the surface of the main body portion 31 has a mounting groove, and the high-voltage connection portion 32 is disposed in the groove. The protective groove 101 of the protective bracket 10 still covers the area where the high-voltage connection portion 32 is located to protect the high-voltage connection portion 32 and effectively reduce the probability of short circuit and fire of the high-voltage connection portion 32.

[0057] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
