Description

Technical Field

[0001] This application relates to the field of vehicle electronic control device arrangement technology, and in particular to a combined bracket and vehicle. Background Technology

[0002] Because the power battery of an electric vehicle is located under the floor and occupies a large space, the space available for electrical control components such as brake air compressor, steering oil pump, water heater, and low-voltage battery is limited, making the placement of these components quite difficult.

[0003] In related technologies, a two-layer structure is often used to arrange electrical control components in a limited space. However, while this method solves the problem of arranging electrical control components, maintenance work on the electrical control components installed on the lower structure requires disassembling and reassembling the upper structure and its electrical control components. This not only significantly increases the workload of maintenance work but also increases the difficulty of maintenance, making maintenance very inconvenient. Utility Model Content

[0004] This application provides a combined bracket and vehicle that can reduce the workload and difficulty of maintenance work and effectively improve the maintenance convenience of electrical control components.

[0005] In a first aspect, this application provides a combined bracket for use in a vehicle frame, the vehicle frame including a first longitudinal beam and a second longitudinal beam spaced apart; the combined bracket includes:

[0006] The first support component is fixedly connected to the first longitudinal beam and the second longitudinal beam;

[0007] At least one second support assembly, located below the first support assembly, for supporting the supported member, wherein the second support assembly is at least partially detachably connected to the first longitudinal beam and the second longitudinal beam; and

[0008] Multiple slings are connected to the first support assembly and the supported member.

[0009] The solution provided in this application detachably connects a second support component below the first support component to the first and second longitudinal beams. A sling is used to connect the second support component to both the first support component and the supported component. This allows the supported component on the second support component to be pulled and secured using the sling before the second support component is removed from the first and second longitudinal beams, preventing it from falling. Therefore, when repairing the supported component on the second support component, the second support component can be directly disassembled, allowing repair of the supported component from below the combined bracket. It is evident that this application effectively reduces the workload and difficulty of maintenance work, and improves the ease of maintenance for electrical control components.

[0010] In conjunction with the first aspect, in some possible implementations, the second support component includes:

[0011] The first connector includes a first main body and a first bent part connected together, wherein the first main body is fixedly connected to the first longitudinal beam;

[0012] The second connector includes a connected second main body and a second bent part, wherein the second main body is fixedly connected to the second longitudinal beam;

[0013] The second support plate has its two ends detachably connected to the first bending portion and the second bending portion, respectively.

[0014] In combination with the first aspect and the above implementation, in some possible implementations, the two ends of the second support plate overlap at the first bend and the second bend;

[0015] Along the extension direction of the vehicle frame, the second support plate has flanges on both sides to restrict the degree of freedom of movement of the second support plate along the extension direction of the vehicle frame.

[0016] In combination with the first aspect and the above implementation, in some possible implementations, the distance between the first end of the second support plate and the first main body is greater than the length of overlap between the second end of the second support plate and the second bent portion.

[0017] Wherein, the first end is the end of the second support plate near the first main body, and the second end is the end of the second support plate near the second main body.

[0018] In combination with the first aspect and the above implementation, in some possible implementations, the bottom of the second support plate is provided with a positioning part, which is further away from the second bending part than the end face of the second end of the second support plate;

[0019] When the positioning part contacts the second bending part, the second end of the second support plate overlaps the second bending part.

[0020] In combination with the first aspect and the above-described implementation, in some possible implementations, both ends of the second support plate are respectively fixedly connected to the first bent portion and the second bent portion by fasteners; or,

[0021] The first end of the second support plate is fixedly connected to the first bent portion by fasteners, and the bottom of the second bent portion is provided with a mating portion, which is fixedly connected to the positioning portion by fasteners.

[0022] In conjunction with the first aspect and the above-described implementations, in some possible implementations, the sling includes a first section, a second section, and a third section; one end of the first section is detachably connected to the first support assembly; one end of the second section is detachably connected to the first support assembly; the third section is located below the supported member, and both ends of the third section are detachably connected to the other ends of the first section and the second section, respectively; or

[0023] The bottom of the supported member is provided with a vibration damping pad, which is fixedly connected to the second support plate;

[0024] The sling includes a sling body and a first connecting portion and a second connecting portion connected to both ends of the sling body. The first connecting portion is connected to the first support assembly. A portion of the second connecting portion is sandwiched between the vibration damping pad and the second support assembly. The end of the second connecting portion is movably connected to the supported member in a position adjustable relative to the supported member.

[0025] In combination with the first aspect and the above-described implementations, in some possible implementations, the combined support further includes:

[0026] Nuts are used to fix the supported member in place.

[0027] A bolt includes a shank and a head, the shank passing through the end of the second connection and threadedly connected to the nut, and the head having a gap with the nut.

[0028] In combination with the first aspect and the above implementation, in some possible implementations, the distance between the head and the second support plate is less than the length of the screw extending into the nut.

[0029] Secondly, this application also provides a vehicle, including:

[0030] The combined stent described in any of the first aspects above.

[0058] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0060] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0061] In the description of the embodiments of this application, the technical terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this application.

[0062] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0065] Because the power battery of an electric vehicle is located under the floor and occupies a large space, the space available for electrical control components such as brake air compressor, steering oil pump, water heater, and low-voltage battery is limited, making the placement of these components quite difficult.

[0066] In related technologies, a two-layer structure is often used to arrange electrical control components in a limited space. However, while this method solves the problem of arranging electrical control components, maintenance work on the electrical control components installed on the lower structure requires disassembling and reassembling the upper structure and its electrical control components. This not only significantly increases the workload of maintenance work but also increases the difficulty of maintenance, making maintenance very inconvenient.

[0067] To address the aforementioned technical problems, this application provides a combined bracket and a vehicle. The combined bracket and vehicle provided in this application will be described in detail below with reference to the accompanying drawings.

[0068] See Figure 1 and Figure 2 The first aspect of this application provides a combined bracket 100, which is disposed on a vehicle frame 300. The vehicle frame 300 includes a first longitudinal beam 301 and a second longitudinal beam 302 spaced apart, which can provide stable support for the combined bracket 100. The combined bracket 100 is used to place a supported component 200, which can be an electrical control component such as a water heater, a low-voltage battery, a brake air compressor, or a power steering pump.

[0069] like Figure 2 As shown, the combined support 100 may include a first support assembly 1, at least one second support assembly 2, and a plurality of slings 3. The first support assembly 1 is fixedly connected to the first longitudinal beam 301 and the second longitudinal beam 302; the second support assembly 2 is located below the first support assembly 1 and is used to support the supported member 200; the second support assembly 2 is at least partially detachably connected to the first longitudinal beam 301 and the second longitudinal beam 302; the slings 3 are connected to the first support assembly 1 and the supported member 200.

[0070] The first support assembly 1 is used to support the water heater, low-voltage battery, and other supported components 200. The first support assembly 1 may include a first support plate 11, which can be directly and fixedly connected to the first longitudinal beam 301 and the second longitudinal beam 302; furthermore, see... Figure 2 The first support assembly 1 may also include multiple transition connectors 12 on the basis of the first support plate 11. The first support plate 11 is fixedly connected to the first longitudinal beam 301 and the second longitudinal beam 302 respectively through the multiple transition connectors 12. The first support assembly 1 may be fixedly connected to the first longitudinal beam 301 and the second longitudinal beam 302 by a permanent connection method such as welding, or it may be fixedly connected to the first longitudinal beam 301 and the second longitudinal beam 302 by a detachable connection method such as fastener connection.

[0071] The second support assembly 2 is located below the first support assembly 1, and a space is reserved between them for the installation of the supported component 200. The second support assembly 2 can support the supported component 200, such as the brake air compressor and the steering pump. The second support assembly 2 is at least partially detachably connected to the first longitudinal beam 301 and the second longitudinal beam 302. When the supported component 200, such as the brake air compressor and the steering pump, on the second support assembly 2 needs maintenance, part or all of the second support assembly 2 can be removed from the first longitudinal beam 301 and the second longitudinal beam 302.

[0072] The second support assembly 2 can support multiple different supported components 200. For example, the second support assembly 2 can simultaneously support a brake air compressor and a power steering pump. Since the different supported components 200 have different sizes, the second support assembly 2 can adopt various structures to accommodate multiple supported components 200 of different sizes. For example, the second support assembly 2 can adopt a single, larger structural component, thus allowing multiple supported components 200 of different sizes to be simultaneously mounted on this single second support assembly 2. Furthermore, considering reducing the weight of the second support assembly 2 and reserving operating space, the second support assembly 2 can also adopt multiple smaller structural components spaced apart. Smaller supported components 200, such as the power steering pump, can be mounted on a single smaller structural component, while larger supported components 200, such as the brake air compressor, can be mounted on multiple smaller structural components.

[0073] There are multiple slings 3, for example, two, three, four, etc., and each sling 3 is connected to the first support assembly 1 and the supported member 200. The slings 3 can be either slings or ropes. The slings 3 can be made of thin metal sheets, such as 2mm-3mm thick steel plates, or woven from high-strength synthetic fibers or metal materials, thus possessing high load-bearing capacity. Before partially or completely removing the second support assembly 2 from the first longitudinal beam 301 and the second longitudinal beam 302, the multiple slings 3 can pull and secure the supported member 200 on the second support assembly 2, preventing the supported member 200 from falling.

[0074] The solution provided in this application embodiment detachably connects the second support component 2 on the lower side of the first support component 1 to the first longitudinal beam 301 and the second longitudinal beam 302. A sling 3 is used to connect the second support component 1 and the supported member 200. Before the second support component 2 is removed from the first longitudinal beam 301 and the second longitudinal beam 302, the sling 3 can be used to pull and secure the supported member 200 on the second support component 2, preventing it from falling. Therefore, when repairing the supported member 200 on the second support component 2, the second support component 2 can be directly disassembled, and the repair of the supported member 200 on the second support component 2 can be achieved from the lower side of the combined bracket 100. It is evident that this application can effectively reduce the workload and difficulty of maintenance operations and improve the convenience of maintaining electrical control components.

[0075] See Figure 2 and Figure 3 In some embodiments, the second support assembly 2 may include a first connector 21, a second connector 22, and a second support plate 23. The first connector 21 includes a first main body portion 211 and a first bent portion 212 connected together, and the first main body portion 211 is fixedly connected to the first longitudinal beam 301; the second connector 22 includes a second main body portion 221 and a second bent portion 222 connected together, and the second main body portion 221 is fixedly connected to the second longitudinal beam 302; the two ends of the second support plate 23 are detachably connected to the first bent portion 212 and the second bent portion 222, respectively.

[0076] The first main body 211 and the second main body 221 can be permanently connected to the first longitudinal beam 301 and the second longitudinal beam 302 by welding or other permanent connection methods, or they can be detachably connected by fasteners or other detachable connection methods. The first bent portion 212 and the second bent portion 222 can be detachably connected to both ends of the second support plate 23 by fasteners, snap-fits, or other methods. When maintenance is required on the supported component 200 on the second support assembly 2, only the second support plate 23 can be removed, thereby further facilitating maintenance work.

[0077] It is understood that the second support plate 23 can be located above the first bend 212 and the second bend 222, or below the first bend 212 and the second bend 222. To fully utilize the supporting function of the first bend 212 and the second bend 222, see [reference needed]. Figure 3 In some embodiments, the two ends of the second support plate 23 overlap at the first bend 212 and the second bend 222.

[0078] Furthermore, along the extension direction perpendicular to the frame 300, the second support plate 23 has flanges 231 on both sides, which can restrict the degree of freedom of movement of the second support plate 23 along the extension direction of the frame 300. In other words, as Figure 3 As shown, along the direction perpendicular to the paper (i.e., the front-to-back direction), the front and rear sides of the second support plate 23 are provided with flanges 231. The flanges 231 can abut against the edges of the first bend 212 and the second bend 222, thus restricting the movement of the second support plate 23 along the direction perpendicular to the paper, thereby improving the stability of the connection between the second support plate 23 and the first bend 212 and the second bend 222. Based on limiting the position of the second support plate 23, designers can set the bending angle and length of the flanges 231 according to actual needs; this embodiment does not specifically limit these aspects.

[0079] As can be seen from the above, along the extension direction perpendicular to the frame 300, the second support plate 23 has flanges 231 on both sides. The flanges 231 serve to prevent the second support plate 23 from moving along the extension direction perpendicular to the frame 300. Therefore, when disassembling the second support plate 23, it is difficult to remove the second support plate 23 from the first bend 212 and the second bend 222 by pulling it back and forth.

[0080] For easy disassembly of the second support plate 23, see [link to relevant documentation]. Figure 3 and Figure 4 In some embodiments, the distance d1 between the first end of the second support plate 23 and the first main body 211 is greater than the overlap length d2 between the second end of the second support plate 23 and the second bent portion 222. The first end is the end of the second support plate 23 closest to the first main body 211, and the second end is the end of the second support plate 23 closest to the second main body 221.

[0081] Thus, by setting the distance d1 between the first end of the second support plate 23 and the first main body 211 to be relatively large, sufficient space for movement can be reserved for the second support plate 23. Figure 3 and Figure 4 As shown, when it is necessary to disassemble the second support plate 23, it can first be moved to the left. Since d1 is greater than d2, after moving a certain distance to the left, the second end of the second support plate 23 will no longer overlap the second bend 222, that is, the second end of the second support plate 23 will detach from the second bend 222. Under the action of gravity, the second end of the second support plate 23 will tilt downward. At this time, by continuing to move the second support plate 23, the disassembly of the second support plate 23 can be achieved quickly and easily. It can be seen that the embodiment of this application can quickly and easily disassemble the second support plate 23.

[0082] When installing the second support plate 23, in order to quickly and reliably achieve the connection between the second support plate 23 and the second bend 222, see [reference needed]. Figure 4 In some embodiments, the bottom of the second support plate 23 is provided with a positioning part 232, which is further away from the second bending part 222 than the end face of the second end of the second support plate 23; wherein, when the positioning part 232 is in contact with the second bending part 222, the second end of the second support plate 23 overlaps the second bending part 222.

[0083] The positioning part 232 can adopt a plate-like structure, a block-like structure, etc., allowing designers to set it flexibly. It is understood that the positioning part 232 is further away from the second bending part 222 than the end face of the second end of the second support plate 23. This allows the side of the positioning part 232 near the second bending part 222 to be offset from the end face of the second end of the second support plate 23, enabling the portion of the second support plate 23 located near the second bending part 222 to overlap with it. Therefore, designers only need to set a reasonable offset distance to ensure effective overlap between the second support plate 23 and the second bending part 222.

[0084] When installing the second support plate 23, the second support plate 23 is moved toward the second bending part 222. When the positioning part 232 abuts against the end face of the second bending part 222, the second support plate 23 and the second bending part 222 can be reliably connected quickly.

[0085] Based on the overlapping connection between the second support plate 23 and the first bent portion 212 and the second bent portion 222, in order to improve the connection strength between the second support plate 23 and the first bent portion 212 and the second bent portion 222, in some embodiments, both ends of the second support plate 23 can be fixedly connected to the first bent portion 212 and the second bent portion 222 respectively by fasteners. For example, mounting holes can be provided at both ends of the second support plate 23 and at both ends of the first bent portion 212 and the second bent portion 222, and fasteners can be inserted through these mounting holes to achieve the connection between the second support plate 23 and the first bent portion 212 and the second bent portion 222. The mounting holes at one or both ends of the second support plate 23 can also be configured as strip holes, thereby facilitating the adjustment of the relative position between the second support plate 23 and the first bent portion 212 and / or the second bent portion 222.

[0086] In other embodiments, see Figure 3 and Figure 4The first end of the second support plate 23 can be fixedly connected to the first bent portion 212 by fasteners. The bottom of the second bent portion 222 is provided with a mating portion 223, which can be fixedly connected to the positioning portion 232 by fasteners. For example, mounting holes can be provided at the first end of the second support plate 23 and the first bent portion 212, and fasteners can be inserted through the mounting holes to achieve the connection between the first end of the second support plate 23 and the first bent portion 212.

[0087] The connection between the second end of the second support plate 23 and the second bent portion 222 can be achieved by connecting the positioning portion 232 at the bottom of the second support plate 23 and the mating portion 223 at the bottom of the second bent portion 222. For example, mounting holes can be provided on the positioning portion 232 and the second bent portion 222, and fasteners can be inserted through these mounting holes to connect the positioning portion 232 and the second bent portion 222, thereby achieving the connection between the second end of the second support plate 23 and the second bent portion 222.

[0088] It should be noted that, since the positioning part 232 is located at the bottom of the second support plate 23 and the mating part 223 is located at the bottom of the second bending part 222, both the positioning part 232 and the mating part 223 are exposed on the lower side of the second support assembly 2. Therefore, when disassembling the second support assembly 2, the position and status of the fasteners connected to the positioning part 232 and the mating part 223 can be directly observed, facilitating the disassembly of the positioning part 232 and the mating part 223.

[0089] The following combination Figures 5 to 11 The specific structure of the sling 3 in the combined support 100 of this application will be described in detail.

[0090] It should be noted that the sling 3 can have various structural forms, and therefore the way the sling 3 is connected to the first support component 1 and the supported component 200 can also be varied.

[0091] In some embodiments, the sling 3 may adopt a U-shaped structure, so that both ends of the sling 3 may be connected to the first support component 1, and the lower part of the sling 3 may pass through the bottom of the supported member 200.

[0092] See Figure 5 and Figure 6Since the sling 3 needs to be replaced after prolonged use, in order to reduce the cost of using the sling 3, in this embodiment of the application, the sling 3 may include a first segment 321, a second segment 322, and a third segment 323; one end of the first segment 321 is detachably connected to the first support component 1; one end of the second segment 322 is detachably connected to the first support component 1; the third segment 323 is located on the lower side of the supported member 200, and both ends of the third segment 323 are detachably connected to the other ends of the first segment 321 and the second segment 322, respectively. It is understood that the service life of the first segment 321, the second segment 322, and the third segment 323 differs due to different stress and other usage conditions. In this embodiment, the first segment 321, the second segment 322, and the third segment 323 are detachably connected. When one of the segments (e.g., the third segment 323) needs to be replaced due to wear or other reasons, only that segment needs to be replaced, without replacing the entire sling 3. Therefore, the cost of using the sling 3 can be effectively reduced.

[0093] To reduce vibration transmission and noise levels, a vibration damping pad 201 is provided at the bottom of the supported member 200, and the vibration damping pad 201 can be fixedly connected to the second support plate 23. At this time, the third section 323 can be sandwiched between the vibration damping pad 201 and the second support assembly 2. This fixes the third section 323 relative to the supported member 200, effectively preventing the sling 3 from detaching from the supported member 200. The third section 323 can be further secured by fasteners inserted through the second support assembly 2, the vibration damping pad 201, and the third section 323.

[0094] In other embodiments, the sling 3 may have a basically straight structure, so one end of the sling 3 may be directly connected to the first support component 1 and the other end may be directly connected to the supported component 200.

[0095] See Figure 7 and Figure 8 The sling 3 may include a sling body 31 and a first connecting part 311 and a second connecting part 312 connected to both ends of the sling body 31. The first connecting part 311 is connected to the first support component 1; the second connecting part 312 is connected to the supported component 200.

[0096] In addition, see Figures 9 to 11For the supported member 200 equipped with the vibration damping pad 201, a portion of the second connecting part 312 can be sandwiched between the vibration damping pad 201 and the second support assembly 2. Furthermore, to avoid a rigid connection between the second connecting part 312 and the supported member 200, which would affect the expansion and contraction of the vibration damping pad 201 and thus its buffering and vibration damping effects, in this embodiment, the end of the second connecting part 312 is movably connected to the supported member 200 in a position adjustable relative to the supported member 200. Thus, when the supported member 200 is subjected to impact, it will not be constrained by the sling 3 and can expand and contract relative to the second support plate 23 along with the vibration damping pad 201, effectively ensuring the normal operation of the vibration damping pad 201.

[0097] There are various ways to achieve the movable connection between the end of the second connecting portion 312 and the supported member 200. In some embodiments, the movable connection can be achieved by using a nut 41 and a bolt 42. For example, see... Figures 9 to 11 The combined bracket 100 may include a nut 41 and a bolt 42. The nut 41 is fixedly connected to the supported member 200. The bolt 42 includes a threaded rod 421 and a head 422. The threaded rod 421 passes through the end of the second connecting part 312 and is threadedly connected to the nut 41. A gap is left between the head 422 and the nut 41. The nut 41 may be fixedly connected to the shell or structural component of the supported member 200 by welding or other methods. It is understood that the end of the second connecting part 312 is sleeved on the threaded rod 421. Since the bolt 42 and the nut 41 are not tightened, and a gap is left between the head 422 of the threaded rod 421 and the nut 41, the end of the second connecting part 312 can move relative to the nut 41. In other words, the nut 41 can move relative to the end of the second connecting part 312, that is, the supported member 200 fixedly connected to the nut 41 can move telescopically relative to the second support plate 23 together with the vibration damping pad 201, effectively avoiding the supported member 200 being constrained by the sling 3 and ensuring the normal operation of the vibration damping pad 201.

[0098] See Figure 10 and Figure 11Considering that bolt 42 and nut 41 may loosen and fall off after prolonged use, in some embodiments, to prevent bolt 42 and nut 41 from falling off after loosening, nut 41 is located on the upper side of head 422; and the distance d3 between head 422 and second support plate 23 is less than the length d4 of screw 421 extending into nut 41. Here, the length d4 of screw 421 extending into nut 41 is the distance between the end face of screw 421 away from head 422 and the side of nut 41 near head 422. With this configuration, when bolt 42 and nut 41 loosen, the head 422 of bolt 42 will move towards second support plate 23 under gravity. Since d3 is less than d4, when head 422 abuts against second support plate 23, screw 421 is still threadedly connected to nut 41. Therefore, bolt 42 will always be connected to nut 41, fundamentally preventing bolt 42 and nut 41 from falling off after loosening.
