Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum pump mounting structure for electric vehicles, and in particular relates to a vacuum pump bracket for electric vehicles. Background Technology

[0002] In gasoline-powered vehicles, the engine intake manifold naturally generates sufficient vacuum to power the vacuum booster, helping the driver easily apply the brake pedal. However, electric vehicles, lacking an engine, lose this natural vacuum source; therefore, an additional vacuum generation and storage system must be established, requiring an electric vacuum pump and vacuum tank.

[0003] A vacuum pump is analogous to the intake manifold of an engine in a gasoline-powered car, actively generating and maintaining the vacuum required by the system. It is typically a piston or vane pump driven by an electric motor. The motor operates according to instructions from the control unit, drawing air from the booster and vacuum tank and releasing it into the atmosphere, thus creating negative pressure (vacuum) within the sealed system. The vacuum pump, vacuum booster, and vacuum tank need to be connected via air hoses.

[0004] In existing technology, vacuum pumps, vacuum boosters, and vacuum tanks are generally connected together by brackets. The vacuum pump bracket is similar to a tray, supporting the motor housing of the vacuum pump from the bottom and sides. The vacuum pump is fixed to the bracket by bolts at the bottom, and the bracket is then fixed to the vehicle body at 2-3 points.

[0005] The existing brackets for installing vacuum pumps do not have reserved space for gas pipes. In the actual installation process in the production workshop, the pipes are often messy and prone to misinstallation. At the same time, because the brackets for installing vacuum pumps are just like a tray, it is difficult for operators to visually determine whether the vacuum pump is installed in place. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a vacuum pump bracket for electric vehicles, which solves the problems of existing tray-like brackets for installing vacuum pumps, which are prone to incorrect pipe installation and make it difficult for operators to visually determine whether the vacuum pump is installed correctly.

[0007] To achieve the above and other related objectives, this utility model provides a vacuum pump bracket for an electric vehicle, comprising: The motherboard is placed horizontally. The left vertical plate is set vertically and its bottom end is fixed to the left end of the main plate; The right vertical plate is set vertically and its bottom end is fixed to the right end of the main board; The left horizontal plate is set horizontally, and its right end is fixed to the top of the left vertical plate; The right horizontal plate is set horizontally, and its left end is fixed to the top of the right vertical plate; The vacuum pump is fixedly installed on the right side of the main board, and is located between the left vertical plate and the right vertical plate; The left horizontal plate, the right horizontal plate, and other supports are fixedly connected.

[0008] Optionally, the right side of the motherboard has at least three fixing holes, the centers of which are not on a straight line, and the vacuum pump is fixedly mounted on the motherboard through the three fixing holes.

[0009] Optionally, the motherboard has a motor hole located between at least three of the fixing holes.

[0010] Optionally, there are four fixing holes arranged symmetrically.

[0011] Optionally, a pipe groove is provided on the left side of the motherboard.

[0012] Optionally, the conduit groove extends to the left vertical plate.

[0013] Optionally, a pipe clamp is installed on the left side of the motherboard.

[0014] Optionally, both the left and right horizontal plates are provided with mounting holes, and soft pads are installed in the mounting holes.

[0015] Optionally, the motherboard, the left vertical plate, the right vertical plate, the left horizontal plate, and the right horizontal plate are formed from a single sheet metal plate through stamping and bending.

[0016] As described above, the vacuum pump bracket for an electric vehicle according to this utility model has at least the following beneficial effects: The vacuum pump bracket of this electric vehicle is a "Ц"-shaped component formed by the main board, left vertical plate, right vertical plate, left horizontal plate, and right horizontal plate. The design of mounting the vacuum pump on the right side of this "Ц"-shaped component provides sufficient space for the pipeline connecting the vacuum pump, thus avoiding messy pipelines and the problem of incorrect installation by operators. At the same time, the design of the left and right vertical plates not only provides installation space for the pipelines, but also allows operators to visually observe the relative height of the vacuum pump and the left and right vertical plates, thereby making a preliminary judgment on the installation position of the vacuum pump, improving installation efficiency and quality.

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0021] Please see Figures 1 to 2 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention.

Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0022] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0023] Please see Figure 1 This utility model provides a vacuum pump bracket for electric vehicles to solve the problems of existing tray-like vacuum pump mounting brackets, which are prone to incorrect pipe installation and make it difficult for operators to visually determine whether the vacuum pump is installed correctly. The bracket includes: like Figure 1 The motherboard 1 shown is placed horizontally, just like a tray-like support in the prior art.

[0024] like Figure 1 The left vertical plate 2 shown is set vertically, and its bottom end is fixed to the left end of the main plate 1.

[0025] like Figure 1 The right vertical plate 3 shown is set vertically, and its bottom end is fixed to the right end of the main plate 1.

[0026] The left vertical plate 2 and the right vertical plate 3 are set opposite to each other.

[0027] like Figure 1The left horizontal plate 4 shown is set horizontally, and its right end is fixed to the top of the left vertical plate 2.

[0028] like Figure 1 The right horizontal plate 5 shown is set horizontally, and its left end is fixed to the top of the right vertical plate 3.

[0029] like Figure 1 As shown, the vacuum pump 12 is fixedly installed on the right side of the main board 1, and is located between the left vertical plate 2 and the right vertical plate 3; that is, the space enclosed by the left vertical plate 2, the main board 1 and the vacuum pump 12 provides installation space for the pipeline connected to the vacuum pump 12, avoiding the mess of the pipeline.

[0030] like Figure 1 As shown, the left horizontal plate 4, the right horizontal plate 5 and other brackets are fixedly connected; the function of the left horizontal plate 4 and the right horizontal plate 5 is to stably connect the vacuum pump bracket and the vacuum pump 12 installed on the vacuum pump bracket to the vehicle body.

[0031] The vacuum pump bracket of this electric vehicle is a "Ц"-shaped component formed by the main board 1, left vertical plate 2, right vertical plate 3, left horizontal plate 4, and right horizontal plate 5. The design of mounting the vacuum pump 12 on the right side of this "Ц"-shaped component provides sufficient space for the pipeline connecting the vacuum pump 12, thus avoiding messy pipelines and the problem of incorrect installation by operators. At the same time, the design of the left vertical plate 2 and the right vertical plate 3 not only provides installation space for the pipeline, but also allows the operator to visually observe the relative height of the vacuum pump 12 and the left vertical plate 2 and right vertical plate 3, thereby making a preliminary judgment on the installation position of the vacuum pump 12, improving installation efficiency and installation quality.

[0032] In another implementation, please refer to Figure 2 The right side of the main board 1 has at least three fixing holes 6. The centers of the three fixing holes 6 are not on a straight line. The vacuum pump 12 is fixedly installed on the main board 1 through the three fixing holes 6. The design of at least three fixing holes 6 is to ensure that the vacuum pump 12 is stably installed on this bracket.

[0033] In another implementation, please refer to Figure 2 The main board 1 has a motor hole 7, which is located between at least three fixing holes 6. The motor of the vacuum pump 12 passes through this hole, which facilitates the installation of the entire vacuum pump 12.

[0034] In another implementation, please refer to Figure 2 There are four fixing holes 6, which are symmetrically arranged to ensure the stable installation of vacuum pump 12 and facilitate the inspection and operation of on-site personnel.

[0035] In another implementation, please refer to Figure 1 and Figure 2The left side of the main board 1 has a pipe groove 8 that extends to the left vertical plate 2, so that the pipes of the vacuum booster and vacuum tank can pass through and connect to the vacuum pump 12. Compared with going around the edge of the bracket, the pipes passing through the pipe groove 8 are neater.

[0036] In another implementation, please refer to Figure 1 and Figure 2 The left side of the motherboard 1 is equipped with a pipe clamp 9, which further improves the neatness of the pipes and avoids the pipes being messy.

[0037] In another implementation, please refer to Figure 2 Mounting holes 11 are provided on both the left horizontal plate 4 and the right horizontal plate 5. A soft pad 10 is installed in the mounting hole 11. That is, the diameter of the mounting hole 11 is larger than the diameter of the corresponding hole on other brackets. This ensures the installation of the soft pad 10. The soft pad 10 has a bidirectional vibration isolation function. It not only prevents the pump's vibration from being transmitted, but also partially isolates the vibration transmitted from the vehicle body, providing a relatively stable mounting base for the vacuum pump 12. At the same time, the soft pad 10 is generally made of rubber, which has a certain degree of flexibility and compressibility. It can compensate for the small dimensional and positional tolerances between the bracket mounting surface and the vehicle body mounting point, ensuring that the vacuum pump 12 can be evenly and snugly fixed, avoiding stress concentration caused by forced assembly.

[0038] In other implementations, such as Figure 2 As shown, the main board 1, the left vertical plate 2, the right vertical plate 3, the left horizontal plate 4, and the right horizontal plate 5 are formed from a sheet metal plate by stamping and bending. Compared with welding, this process has lower production costs and easier quality control.

[0039] In summary, this utility model, through the "Ц"-shaped component formed by the main board 1, left vertical plate 2, right vertical plate 3, left horizontal plate 4, and right horizontal plate 5, with the vacuum pump 12 installed on the right side of this "Ц"-shaped component, provides sufficient space for the pipeline connecting the vacuum pump 12, thus avoiding messy pipelines and the problem of incorrect installation by operators. Simultaneously, the design of the left vertical plate 2 and the right vertical plate 3 not only provides installation space for the pipeline but also allows operators to visually observe the relative height of the vacuum pump 12 and the left and right vertical plates 2 and 3, thereby making a preliminary judgment on the installation position of the vacuum pump 12, improving installation efficiency and quality. Therefore, this utility model effectively overcomes the shortcomings of the prior art and has high industrial application value.

[0040] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
