Detailed implementation manners
[0039] To make the objectives, technical solutions, and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.
[0040] This embodiment relates to an engine hood. Referring to Figures 1 to 3 as shown, Figure 1 it shows a schematic structural diagram of the engine hood from an overhead view, Figure 2The structural schematic diagram of the engine decorative cover in a bird's-eye view is shown. The engine decorative cover includes an engine decorative cover body 100 and a shielding member 101. Among them, the engine decorative cover body 100 is adapted to cover the engine body, so that it can play a role in dust prevention, noise reduction and beautifying the space inside the engine compartment. The engine decorative cover body 100 has a through hole 102.
[0041] The shielding member 101 is movably assembled on the engine decorative cover body 100 and is configured to switch between a closed state and an open state. Among them, in the closed state, the shielding member 101 moves to the through hole 102 to block the through hole 102. In the open state, the shielding member 101 moves away from the through hole 102 to make the through hole 102 unblocked.
[0042] Correspondingly, in order to drive the shielding member 101 to move, the engine decorative cover may further include a transmission member 1052. For example Figure 5 and Figure 6 As shown, the transmission member 1052 may be two threaded rods parallel to each other. Both threaded rods are rotatably connected to the engine decorative cover body 100 and are threadedly connected to the shielding member 101. Thus, when the two threaded rods are rotated, the shielding member 101 can translate. For example, when the two threaded rods are rotated forward, the shielding member 101 can move to the through hole 102, and when the threaded rods are rotated backward, the shielding member 101 can move away from the through hole 102.
[0043] As described above, when it is necessary to reduce the heat dissipation of the engine decorative cover to the engine body, the shielding member 101 can be configured to be in the open state, so that the through hole 102 is in a flowing state, and the hot air generated when the engine heats up can quickly flow from the through hole 102 to the upper part of the engine decorative cover body 100, avoiding the accumulation of hot air under the engine decorative cover body 100 and affecting the heat dissipation of the engine body.
[0044] At the same time, when the heat generation of the engine body is relatively low, the shielding member 101 can be configured to be in the closed state to block the through hole 102, which can prevent the noise generated during the operation of the engine body from being transmitted out through the through hole 102, so it is beneficial to ensure the noise reduction ability of the engine decorative cover body 100.
[0045] Generally, the change of the working state of the engine body is not instantaneous and large-scale. The situation where the heat generation of the engine body is relatively low or high usually lasts for a certain period of time.
[0046] For example, when the vehicle needs to travel at a low speed in the city, the engine load is small and the heat generation is low. At this time, the operator has sufficient time to manually rotate the threaded rod in advance when the vehicle is parked, switch the shielding member 101 to the closed state, block the through hole 102, and prevent the noise generated during the operation of the engine from being transmitted out through the through hole 102, which can preferably ensure the noise reduction ability of the engine decorative cover body 100.
[0047] When the vehicle needs to travel at a high speed for a long time or climb a heavy load, etc., the engine body has a large load and high heat generation. The operator can also manually rotate the threaded rod at a suitable time such as when the vehicle is parked or during a break in the middle, and switch the shielding member 101 to the open state, which can preferably ensure the heat dissipation ability of the engine body.
[0048] In one example, continue to refer to Figure 1 As shown, the side of the engine decorative cover body 100 facing the engine body has a concave structure 103, and the concave structure protrudes in a direction away from the engine body. For example, the concave structure 103 can be located inside the engine decorative cover body 100. The through hole 102 is located on the concave structure 103. It should be noted that the inner side of the engine decorative cover body 100 refers to the side facing the engine body after the engine decorative cover body 100 covers the engine body, and the outer side is opposite to the inner side and is the side of the engine decorative cover body 100 away from the engine body.
[0049] Among them, since the bottom surface area of the concave structure 103 is higher than other positions of the engine decorative cover body 100, the hot air around the engine body tends to converge in the concave structure 103 during the rising process. And the through hole 102 is located on the concave structure 103. Therefore, it is beneficial for the hot air to flow out smoothly from the through hole 102, and thus, it is beneficial for the heat dissipation of the engine body.
[0050] In one example, continue to refer to Figure 1 、 Figure 3 and Figure 4 As shown, the bottom surface of the concave structure 103 is inclined, and the position of the bottom surface close to the first side of the concave structure 103 is higher than the position of the bottom surface far from the first side of the concave structure 103. The through hole 102 is located on the first side of the concave structure 103. For example, the through hole 102 can be located on the side wall of the first side of the concave structure 103. In this way, the inclined bottom surface of the concave structure 103 can guide the rising hot air, and thus, it is beneficial for the hot air to flow out from the through hole 102 located on the first side of the concave structure 103.
[0051] In one example, refer to Figure 5 and Figure 6As shown, the shielding member 101 can be located inside the concave structure 103 to block the through hole 102, but the shielding member 101 can also be located outside the concave structure 103 to block the through hole 102. In this embodiment, taking the Figure 6 shielding member 101 shown as an example of being located inside the concave structure 103, the threaded rod can pass through the bottom wall of the concave structure 103 and be threadedly connected to the shielding member 101. Thus, a person can rotate the threaded rod from the outside of the engine decorative cover body 100, thereby realizing the control of switching the shielding member 101 between the closed state and the open state.
[0052] In one example, referring to Figure 6 shown, the shielding member 101 can have a threaded sleeve 1011. The internal thread of the threaded sleeve 1011 matches the external thread of the threaded rod. The threaded rod can pass through the bottom wall of the concave structure 103 and extend into the threaded sleeve 1011, and be threadedly connected to the threaded sleeve 1011. Thus, the threaded rod can be threadedly connected to the shielding member 101 through the threaded sleeve 1011.
[0053] In one example, one end of the threaded rod located outside the concave structure 103 has an adjusting cap. Thus, a person can use tools such as a screwdriver to turn the adjusting cap, which is beneficial to improving the adjustment efficiency of the shielding member 101 and has a low cost.
[0054] In one example, the number of through holes 102 can be multiple, and the multiple through holes 102 are spaced apart in the horizontal direction. For example Figure 1 shown, the multiple through holes 102 can be spaced apart in the horizontal direction on the first side wall of the concave structure 103. Thus, it is beneficial to improve the heat dissipation efficiency of the engine body.
[0055] In one example, referring to Figures 7 to 9 shown, the engine decorative cover further includes an engine decorative cover connection mechanism 200. The engine decorative cover connection mechanism 200 includes a first mounting component 1, a second mounting component 2, a first elastic member 3, and a second elastic member 4.
[0056] Among them, referring to Figure 9 shown, the first mounting component 1 includes a first mounting member 11 and a first moving member 12. The first mounting member 11 has a first guiding groove 111 and a second guiding groove 112. The opening of the second guiding groove 112 is located on the side wall of the first guiding groove. The first moving member 12 is biased by the first elastic member 3 to protrude from the second guiding groove 112. Thus, a part of the first moving member 12 can extend into the first guiding groove 111. For example, one end of the first moving member 12 facing the opening of the second guiding groove 112 can have a limiting end 121, and the limiting end 121 can extend into the first guiding groove 111.
[0057] For exampleFigure 9 and Figure 11 As shown, the first elastic member 3 can be connected between the bottom of the second guiding groove 112 and the second moving member 22. Thus, when the limiting end 121 is subjected to a force towards the bottom of the second guiding groove 112, the limiting end 121 can retract towards the bottom of the second guiding groove 112, and the first elastic member 3 can be compressed. Among them, the first elastic member 3 can be a spring as shown in Figure 9 or an elastic arm or the like.
[0058] Continue to refer to Figure 9 As shown, the second mounting assembly 2 includes a second mounting member 21 and a second moving member 22. The second mounting member 21 has a limiting structure 211, and the second elastic member 4 is elastically compressed between the limiting structure 211 and the bottom of the first guiding groove 111. The second moving member 22 is movably assembled on the second mounting member 21.
[0059] Among them, the first mounting member 11 and the second mounting member 21 are adapted to be connected to the engine decorative cover body 100 and other vehicle components respectively. For example, the first mounting member 11 can be connected to the engine decorative cover body 100, and the second mounting member 21 can be connected to other vehicle components. Or the second mounting member 21 can be connected to the engine decorative cover body 100, and the first mounting member 11 can be connected to other vehicle components. In this embodiment, the first mounting member 11 is connected to the engine decorative cover body 100 and the second mounting member 21 is connected to other vehicle components as an example. Among them, other vehicle components can be the engine body or other parts such as the vehicle sheet metal. In this embodiment, other vehicle components are the engine body as an example.
[0060] And when the engine decorative cover connecting mechanism 200 is in a stable state, the first moving member 12 is located between the limiting structure 211 and the second moving member 22 and blocks the second moving member 22 from moving away from the bottom of the first guiding groove 111. When the limiting structure 211 or the second moving member 22 moves towards the bottom of the first guiding groove 111, or the second moving member 22 moves away from the bottom of the first guiding groove 111, the first moving member 12 can be pushed to retract towards the bottom of the second guiding groove 112 without hindering the movement of the second mounting member 21.
[0061] For example, the second moving member 22 may be configured to move closer to or away from the limiting structure 211 along the second axis 111a of the first guiding groove 111, and the second moving member 22 is located on the side of the limiting structure 211 away from the bottom of the first guiding groove 111. Thus, when the limiting structure 211 moves from outside the first guiding groove 111 towards the bottom of the first guiding groove 111, it can enter the first guiding groove 111 prior to the first guiding groove 111. Furthermore, the limiting end 121 of the first moving member 12 may be located between the limiting structure 211 and the second moving member 22, and block the second moving member 22 from moving away from the bottom of the first guiding groove 111. Also, since the second elastic member 4 is elastically compressed between the limiting structure 211 and the bottom of the first guiding groove 111, the first mounting assembly 1 and the second mounting assembly 2 are locked to each other. At this time, the engine hood connecting mechanism 200 is in a stable state.
[0062] In the stable state, continuing to move the second mounting member 21 towards the bottom of the first guiding groove 111 can drive the second moving member 22 towards the bottom of the first guiding groove 111, and then push the first moving member 12 to retract towards the bottom of the second guiding groove 112 and compress the second elastic member 4, so that both the second moving member 22 and the limiting structure 211 are located on the side of the limiting end 121 facing the bottom of the first guiding groove 111. At this time, then moving the second mounting member 21 away from the bottom of the first guiding groove 111, the movement of the second moving member 22 is obstructed by the limiting end 12. Until the limiting structure 211 abuts against the second moving member 22, the second moving member 22 can move away from the bottom of the first guiding groove 111 together with the limiting structure 211. Furthermore, the first moving member 12 can be retracted towards the bottom of the second guiding groove 112 without obstructing the movement of the second mounting member 21. Thus, the first mounting assembly 1 and the second mounting assembly 2 are separated.
[0063] As described above, the first mounting member 11 of the first mounting assembly 1 and the second mounting member 21 of the second mounting assembly 2 are adapted to be respectively connected to the engine hood body 100 and the engine body. Thus, when the engine hood connecting mechanism 200 is in a stable state, the engine hood body 100 can be fixedly installed on other vehicle components. When the first mounting assembly 1 and the second mounting assembly 2 are separated, the engine hood body 100 is separated from the engine body. Thus, the rapid installation and disassembly of the engine hood can be realized.
[0064] Correspondingly, in order to enable the limiting structure 211 or the second moving member 22 to move towards the bottom of the first guiding groove 111, or the second moving member 22 to move away from the bottom of the first guiding groove 111, both can push the first moving member 12 to retract towards the bottom of the second guiding groove 112 without obstructing the movement of the second mounting member 21.
[0065] For example Figure 9As shown, the second side of the limiting structure 211, the first side of the second moving member 22 and the second side of the limiting end 121 all have a structural surface that is tilted relative to the second axis 111a, so that when the second side of the limiting structure 211 abuts against and moves toward the first side of the limiting structure 211, when the first side of the limiting structure 211 abuts against and moves toward each other, when the first side of the limiting structure 211 abuts against and moves toward each other, and when the second side of the second moving member 22 abuts against and moves toward each other, the first moving member 12 can be pushed to retract toward the bottom of the second guide groove 112 without hindering the movement of the second mounting member 21. It should be noted that the first side refers to a side that deviates from the bottom of the first guide groove 111, and the second side is opposite to the first side, and is a side toward the bottom of the first guide groove 111.
[0066] In order to prevent the second movable member 22 from moving away from the bottom of the first guide groove 111 when the first movable member 12 is located between the limiting structure 211 and the second movable member 22, the first side of the limiting structure 211 and the second side of the limiting end 121 can be planes perpendicular to the second axis 111a.
[0067] In one example, continue to refer to Figure 9 As shown, the second elastic member 4 is located in the first guide groove 111, and the second elastic member 4 includes a compression spring 41 and a pressing portion 42. The first end of the compression spring 41 is connected to the bottom of the first guide groove 111. The pressing portion 42 is also movably assembled in the first guide groove 111 along the second axis 111a, and is connected to the second end of the compression spring 41. When the limiting structure 211 extends into the first guide groove 111, the pressing portion 42 can abut against the limiting structure 211.
[0068] Thus, on the one hand, the second elastic member 4 is located in the first guide groove 111, which is beneficial to prevent the second elastic member 4 from being damaged, thereby extending the service life. On the other hand, the pressing portion 42 can be movably assembled in the first guide groove 111, and when the pressing portion 42 abuts against the limiting structure 211, it can have higher stability.
[0069] In one example, continue with reference 1 and combine Figure 9 As shown, the first mounting member 11 is connected to the lower side of the engine decorative cover body 100 , the second mounting member 21 is suitable for connecting with other vehicle components, the opening of the first guide groove 111 faces downward, and the limiting structure 211 is located above the second movable member 22 .
[0070] For example Figure 9As shown, since the first mounting member 11 is connected to the lower side of the engine trim cover body 100, the limiting structure 211 can move upward relative to the first guiding groove 111 by pressing down the engine trim cover body 100, and move from the lower side of the limiting end 121 to the upper side of the limiting end 121. As a result, the limiting end 121 can be located between the limiting structure 211 and the second moving member 22 on the moving path, and the second elastic member 4 forces the limiting structure 211 to abut against the limiting end 121, thereby locking the first mounting assembly 1 and the second mounting assembly 2 to each other.
[0071] Moreover, when the first mounting assembly 1 and the second mounting assembly 2 are locked to each other, the engine trim cover body 100 can be first pressed down to make both the limiting structure 211 and the second moving member 22 located on the upper side of the limiting end 121, and then the engine trim cover body 100 can be lifted upward to make the second moving member 22 move downward relative to the first guiding groove 111, thereby realizing the separation of the first mounting assembly 1 and the second mounting assembly 2.
[0072] In one example, as shown in Figure 8 the first mounting assembly 1 further includes a first connecting member 13, and the first connecting member 13 and the second mounting member 21 are respectively adapted to be connected to the engine trim cover body 100 and other vehicle components. For example, the first connecting member 13 and the engine trim cover body 100 can be integrally formed or two independent structural members.
[0073] Wherein, the first connecting member 13 has a first thread, and the first axis 13a of the first thread extends along the second axis 111a of the first guiding groove 111. For example, as shown in Figure 8 the first axis 13a can extend in the vertical direction. The first mounting member 11 has a second thread, and the second thread and the first thread are internally and externally threaded to match each other.
[0074] For example, the first thread can be an external thread and the second thread can be an internal thread. However, it can also be as shown in Figure 8 where the first thread is an internal thread and the second thread is an external thread. In this embodiment, taking the example where the first thread is an internal thread and the second thread is an external thread as shown in Figure 8 the lower side of the first connecting member 13 can have a threaded hole, the first thread is the thread of the threaded hole, the first mounting member 11 is cylindrical, and the second thread can be located on the outer wall of the first mounting member 11.
[0075] Thus, the first mounting member 11 can be connected to the engine decorative cover body 100 through the first connecting member 13. Moreover, by rotating the first mounting member 11, the length of the first mounting member 11 extending from the threaded hole can be adjusted, thereby the distance between the engine decorative cover body 100 and the engine body can be adjusted, and engines of different sizes can also be accommodated. In addition, when the first mounting member 11, the first moving member 12, the first elastic member 3 and the second elastic member 4 are damaged, they can be conveniently replaced.
[0076] In one example, with continued reference to Figure 8 and in combination with Figure 10 as shown, the second mounting assembly 2 further includes a mounting seat 23 and a fixing member. The mounting seat 23 is fixedly connected to the first end of the second mounting member 21, and the limiting structure 211 is located at the second end of the second mounting member 21. Among them, the mounting seat 23, the limiting structure 211 and the second mounting member 21 can be integrally formed or independent structural members. Both the mounting seat 23 and the engine body have mounting holes 231. The fixing member can be rod-shaped, and the rod-shaped fixing member can sequentially pass through the mounting hole 231 of the mounting seat 23 and the mounting hole 231 of the engine body, thereby realizing the fixed connection between the mounting seat 23 and the engine body.
[0077] For example, the fixing member can be a bolt. For example, the nut of the bolt abuts against the mounting seat 23, and the second end of the bolt can sequentially pass through the mounting hole 231 of the mounting seat 23 and the mounting hole 231 of the engine body and be screwed onto the engine body. Thus, the mounting seat 23 is fixedly connected to the engine body.
[0078] In another example, the fixing member can be a pin. One end of the pin has a pin cap that abuts against the mounting seat 23. The second end of the pin sequentially passes through the mounting hole of the mounting seat 23 and the mounting hole 231 of the engine body and is riveted to the engine body.
[0079] In another example, the fixing member can be a screw. One end of the screw has a screw cap that abuts against the mounting seat 23. The second end of the screw passes through the mounting hole of the mounting seat 23 and is screwed into the mounting hole 231 of the engine body. Among them, the mounting hole 231 of the engine body is a screw hole.
[0080] In one example, with continued reference to Figure 8 as shown, the first guiding groove 111 is circular, and the second axis 111a of the first guiding groove 111 is collinear with the first axis 13a. The second guiding groove 112 communicates with the first guiding groove 111 from the side wall of the first guiding groove 111.
[0081] Wherein, when the limiting structure 211 and the second moving member 22 extend into the first guiding groove 111, the projection profiles of the limiting structure 211 and the second moving member 22 along the second axis 111a are both circles centered on the second axis 111a.
[0082] For example Figure 8 and in combination with Figure 11 As shown, the limiting structure 211 can be frustum-shaped, the second moving member 22 can be frustum-shaped with a through-hole in the center, the through-hole extends along the third axis of the second moving member 22, the second moving member 22 can be sleeved on the second fixing member through the through-hole, the fourth axis of the limiting structure 211 is collinear with the third axis, and the side with the larger diameter of the limiting structure 211 faces the side with the larger outer diameter of the second moving member 22. Thus, in the case where the first mounting member 11 extends out of the threaded hole by any length, the first mounting assembly 1 and the second mounting assembly 2 can be conveniently matched, and thus, the installation and disassembly efficiency of the engine decorative cover can be improved.
[0083] In one example, referring to Figure 11 as shown, the first mounting member 11 has a plurality of second guiding grooves 112. For example, the number of the second guiding grooves 112 can be three as Figure 11 shown, but the number of the second guiding grooves 112 can also be four, five, etc. The plurality of second guiding grooves 112 can be evenly spaced around the first axis and the second axis 111a.
[0084] Moreover, the number of the first moving members 12 and the first elastic members 3 can also be multiple, and the first moving members 12, the first elastic members 3 and the second guiding grooves 112 are in one-to-one correspondence. The first moving members 12 are movably assembled in the corresponding second guiding grooves 112. The first elastic members 3 can be connected between the second mounting member 21 and the corresponding second moving members 22, and can force the limiting ends 121 of the corresponding first moving members 12 to move to the moving path.
[0085] Thus, it is beneficial to improve the connection stability between the first mounting assembly 1 and the second mounting assembly 2.
[0086] In one example, referring to Figure 4 as shown, a dust-proof member 104 is provided in the through-hole 102. For example, the dust-proof member 104 can be a filter net or a filter plate, etc. Thus, the dust-proof member 104 can block the dust from the outside and improve the dust-proof effect.
[0087] In one example, as Figure 1 shown, the number of the engine decorative cover connection mechanisms 200 can be four, and the four engine decorative cover connection mechanisms 200 can be respectively connected to the four corners of the engine decorative cover body 100. Thus, the connection stability of the engine decorative cover body 100 on the engine body can be improved.
[0088] In one example, the engine cowl further includes a driving component 105 and a controller 106. The driving component 105 is used to drive the shielding member 101 to move, and the controller 106 is in signal connection with the driving component 105.
[0089] Among them, referring to Figure 6 As shown, the driving component 105 may include a driving member 1051 and a transmission member 1052. The transmission member 1052 may be two threaded rods parallel to each other. Both threaded rods are rotatably connected to the engine cowl body 100, and the threaded rods may pass through the bottom wall of the concave structure 103 and be threadedly connected to the shielding member 101. The driving member 1051 may be two motors. Both motors are fixed on the engine cowl body 100, and each motor corresponds to a threaded rod. The output shaft of the motor is fixedly connected to the corresponding threaded rod. Thus, when the motor is started, the threaded rod can rotate. Both motors are in signal connection with the controller 106. For example, the controller 106 may be integrated in the vehicle's central control screen. The operator can send instructions to the two motors through the controller 106 in the central control screen, so that the output shafts of the two motors rotate simultaneously to drive the shielding member 101 to move, or the output shafts of the two motors stop simultaneously to fix the position of the shielding member 101, thereby realizing the switching of the shielding member 101 between the closed state and the open state.
[0090] In this way, the operator does not need to get out of the vehicle to manually switch the state of the shielding member 101, and can switch the state of the shielding member 101 according to the driving conditions of the vehicle, improving the convenience.
[0091] In one example, the engine cowl further includes a temperature sensor 107. The temperature sensor 107 is in signal connection with the controller 106. The temperature sensor 107 is used to detect the temperature below the engine cowl body 100 and send the detected temperature signal to the controller 106. The controller 106 sends an instruction to the driving component 105 according to the received temperature signal.
[0092] For example, the temperature sensor 107 may be installed inside the concave structure 103. The temperature sensor 107 may send the detected temperature signal to the controller 106. The controller 106 may send an instruction to the motor according to the received temperature signal. When the temperature detected by the temperature sensor 107 exceeds the threshold, the controller 106 may send a signal to the motor so that the shielding member 101 is configured to be in the open state. When the temperature detected by the temperature sensor 107 is less than or equal to the threshold, the controller 106 may send a signal to the motor so that the shielding member 101 is configured to be in the closed state. Therefore, the heat generation amount of the engine body can be more accurately sensed according to the temperature signal detected by the temperature sensor 107, and then the automatic switching of the shielding member 101 between the two states can be realized.
[0093] This embodiment also discloses an engine, which includes an engine body and an engine decorative cover as described in any one of the first aspects. The engine decorative cover body 100 of the engine decorative cover covers the engine body.
[0094] In the solution shown in the present disclosure, when it is necessary to reduce the heat dissipation of the engine decorative cover to the engine body, the shielding member 101 can be configured to be in an open state, so that the through hole 102 is in a flowing state. The hot air generated when the engine generates heat can quickly flow from the through hole 102 to the upper part of the engine decorative cover body 100, avoiding the accumulation of hot air under the engine decorative cover body 100 and affecting the heat dissipation of the engine body. At the same time, when the heat generated by the engine body is relatively low, the shielding member 101 can be configured to be in a closed state to block the through hole 102, which can prevent the noise generated during the operation of the engine body from being transmitted through the through hole 102, and thus is beneficial to ensuring the noise reduction ability of the engine decorative cover body 100.
[0095] This embodiment also discloses a vehicle, which has an engine as described in the second aspect.
[0096] In the solution shown in the present disclosure, when it is necessary to reduce the heat dissipation of the engine decorative cover to the engine body, the shielding member 101 can be configured to be in an open state, so that the through hole 102 is in a flowing state. The hot air generated when the engine generates heat can quickly flow from the through hole 102 to the upper part of the engine decorative cover body 100, avoiding the accumulation of hot air under the engine decorative cover body 100 and affecting the heat dissipation of the engine body. At the same time, when the heat generated by the engine body is relatively low, the shielding member 101 can be configured to be in a closed state to block the through hole 102, which can prevent the noise generated during the operation of the engine body from being transmitted through the through hole 102, and thus is beneficial to ensuring the noise reduction ability of the engine decorative cover body 100.
