Description

Technical Field

[0001] This utility model relates to the field of engine hood technology, specifically to an injection-molded engine hood for electric vehicles. Background Technology

[0002] In the research and development and production of electric vehicles, lightweight design has become a crucial issue, as it directly affects the driving range, fuel efficiency, and overall performance of electric vehicles. Injection molding technology, as an efficient and economical plastic processing method, plays an increasingly important role in the manufacturing of electric vehicles. In the field of electric vehicles, injection-molded hoods, as important body coverings, not only protect the internal mechanical structure of the vehicle but also directly affect the vehicle's aerodynamic performance and heat dissipation efficiency. In the rapid development of electric vehicles, the design and performance of injection-molded hoods, as key components of the body, have a significant impact on the overall vehicle performance, safety, and energy efficiency. However, existing injection-molded hoods for electric vehicles generally lack in the design of air intake mechanisms, which limits the functional diversity of the hood.

[0003] For example, the one-piece injection molded electric vehicle hood (announcement number: CN106828612B) has advantages such as high strength and toughness, meeting the performance requirements of electric vehicle hoods, simple manufacturing process, high appearance precision, light weight, and low cost.

[0004] The aforementioned device lacks an air intake mechanism. Although electric vehicles do not have a traditional engine that needs cooling, their key components such as battery packs and motors still generate a lot of heat under long-term high-load operation. The lack of an air intake mechanism in the hood cannot effectively guide external cold air into the vehicle to dissipate heat from the key components, which may lead to heat accumulation and affect vehicle performance and service life. This problem is particularly prominent in high-temperature environments. Therefore, we need to propose an injection-molded hood for electric vehicles. Utility Model Content

[0005] The purpose of this invention is to provide an injection-molded engine hood for electric vehicles, which aims to solve the problem that existing engine hoods lack air intake mechanisms. Although electric vehicles do not have engines that need to be cooled in the traditional sense, their key components such as battery packs and motors still generate a lot of heat under long-term high-load operation. Engine hoods without air intake mechanisms cannot effectively guide external cold air into the vehicle to dissipate heat from key components, which may lead to heat accumulation and affect vehicle performance and service life. This problem is particularly prominent in high-temperature environments.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An injection-molded hood for an electric vehicle includes a hood body. The top of the hood body has two sets of through slots, each containing an air intake hood. The bottom of each air intake hood is fixedly connected to several sets of guide vanes, which are equidistantly arranged. One side of the air intake hood has an opening. The bottom of the air intake hood has two sets of protrusions symmetrically fixedly connected to it. Two sets of locking blocks are fixedly connected to one side wall of each of the two sets of protrusions. The tops of both sets of locking blocks abut against the bottom of the hood body. The bottom of the hood body is fixedly connected to four sets of fixing blocks, each containing a locking component for positioning the locking blocks.

[0008] Preferably, the locking assembly includes a positioning sleeve installed inside the fixing block, a movable rod slidably inserted inside the positioning sleeve, one end of the movable rod being inserted inside the locking block, and the other end of the movable rod being fixedly connected to a pull block.

[0009] Preferably, it also includes a locking spring, one end of which is fixedly connected to one side wall of the pull block, and the other end of which is fixedly connected to one end of the positioning sleeve, and the locking spring is movably sleeved on the outer wall of the movable rod.

[0010] Preferably, the fixing block has an installation hole inside that matches the positioning sleeve, and the positioning sleeve is fixedly embedded inside the installation hole.

[0011] Preferably, a positioning blind hole adapted to the movable rod is provided on one side wall of the card block, and one end of the movable rod is inserted into the positioning blind hole.

[0012] Preferably, the top of the card block is fixedly connected with three sets of inserts, and the bottom of the hood body is provided with insertion holes that are adapted to the inserts, with the top of the inserts inserted into the inside of the insertion holes.

[0013] Preferably, the air inlet hood is trapezoidal in shape, and an isolation mesh is fixedly embedded inside the opening.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by creating a through groove on the hood body and cooperating with the air intake cover, deflector, and opening, allows airflow to enter the interior of the air intake cover when the car is in motion. The deflector then directs the airflow towards the motor, effectively cooling the motor and other critical components. Furthermore, the use of protrusions, clips, fixing blocks, and locking components enables quick positioning of the air intake cover, facilitating its disassembly, replacement, or maintenance and improving maintenance efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution:

[0023] An injection-molded hood for an electric vehicle includes a hood body 1. The top of the hood body 1 has two sets of through slots 2, each containing an air intake hood 3. Several sets of guide vanes 14 are fixedly connected to the bottom of the air intake hood 3, and these guide vanes 14 are equidistantly arranged. An opening 4 is provided on one side of the air intake hood 3. By creating the through slots 2 on the hood body 1 and cooperating with the air intake hood 3, guide vanes 14, and opening 4, when the vehicle is in motion, the airflow from the front enters the interior of the air intake hood 3 and is concentrated towards the motor location by the guide vanes 14, thus effectively dissipating heat from the motor and other critical components. The air intake hood 3 has two sets of protrusions 5 symmetrically fixedly connected to its bottom. Two sets of locking blocks 6 are fixedly connected to one side wall of each of the two sets of protrusions 5. The tops of the two sets of locking blocks 6 abut against the bottom of the hood body 1. Four sets of fixing blocks 7 are fixedly connected to the bottom of the hood body 1. The four sets of fixing blocks 7 are respectively provided with locking components 8 for positioning the locking blocks 6. By setting the protrusions 5, locking blocks 6, fixing blocks 7 and locking components 8 together, the air intake hood 3 is quickly positioned, which makes it easy to disassemble, replace or maintain the air intake hood 3, thus improving maintenance efficiency.

[0024] The locking component 8 includes a positioning sleeve 801, which is installed inside the fixing block 7. A movable rod 802 is slidably inserted inside the positioning sleeve 801. One end of the movable rod 802 is inserted into the inside of the locking block 6, and the other end of the movable rod 802 is fixedly connected to a pull block 803.

[0025] It also includes a locking spring 804, one end of which is fixedly connected to one side wall of the pull block 803, and the other end of which is fixedly connected to one end of the positioning sleeve 801. The locking spring 804 is movably sleeved on the outer wall of the movable rod 802.

[0026] By adopting the above case, when the air inlet cover 3 needs to be replaced or maintained after a long period of use, the pull block 803 can be pulled first. At this time, the locking spring 804 is in the stretched state, and the movable rod 802 can be moved until the movable rod 802 is separated from the locking block 6. At this time, the air inlet cover 3 can be pulled out downwards to complete the disassembly operation, which is convenient for the maintenance of the air inlet cover 3.

[0027] The fixing block 7 has an installation hole 9 inside that matches the positioning sleeve 801. The positioning sleeve 801 is fixedly embedded inside the installation hole 9. By setting the installation hole 9, the positioning sleeve 801 is positioned.

[0028] A positioning blind hole 10 adapted to the movable rod 802 is provided on one side wall of the card block 6, and one end of the movable rod 802 is inserted into the interior of the positioning blind hole 10.

[0029] The top of the card block 6 is fixedly connected with three sets of plugs 11, and the bottom of the hood body 1 is provided with a socket 12 that is compatible with the plugs 11. The top of the plug 11 is inserted into the socket 12.

[0030] Specifically, when a new air inlet cover 3 needs to be installed, the insert post 11 on the top of the air inlet cover 3 can be inserted into the inside of the insertion hole 12. When the positioning blind hole 10 is aligned with one end of the movable rod 802, the pull block 803 can be released. The pull force of the locking spring 804 can then be used to firmly insert one end of the movable rod 802 into the inside of the positioning blind hole 10, thereby achieving the effect of quick installation and removal of the air inlet cover 3.

[0031] The air inlet hood 3 is trapezoidal in shape, which can increase the air intake area. An isolation net 13 is fixedly installed inside the opening 4. By setting the isolation net 13, it plays the role of filtering out external debris.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
