Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle technology, specifically to a vehicle body structure and a vehicle. Background Technology
[0002] The current design trend for new energy vehicles is towards smaller and smaller grille openings. Therefore, in some range-extended models, the utilization rate of the grille opening area needs to be increasingly higher. However, because the front bumper has a front anti-collision beam located at the grille position on the front bumper, this beam often obstructs part of the grille opening, thus affecting the utilization rate of the grille area.
[0003] To address the issue of the front bumper beam obstructing the air intake grille, the conventional approach is to increase the opening area of the air intake grille. While this design ensures the required air intake area at the grille, it increases the complexity of the overall vehicle design. Furthermore, an excessively large grille opening can increase wind resistance and negatively impact the vehicle's overall performance.
[0004] Therefore, how to solve the problem of the front bumper beam obstructing the air intake grille so that the opening area of the air intake grille can meet the air intake area requirements for cooling the thermal management module when the vehicle is operating under extreme high power conditions is an urgent technical problem to be solved. Utility Model Content
[0005] In view of the problems existing in the prior art, the present invention provides a vehicle body structure and vehicle to improve the problem of the front anti-collision beam obstructing the air intake grille, so that the opening area of the grille can meet the thermal management air intake area requirements of new energy vehicles with high power powertrains.
[0006] To achieve the above and other related objectives, the first aspect of this utility model provides a vehicle body structure, which includes a front engine compartment, a front bumper, a front anti-collision beam, and a moving mechanism. The front bumper is provided with an air intake grille, which is connected to the front engine compartment. The front anti-collision beam is movably disposed in the front engine compartment and located on the side close to the air intake grille. The moving mechanism is disposed in the front engine compartment and drives the front anti-collision beam to move, thereby changing the obstruction of the air intake grille by the front anti-collision beam.
[0007] The beneficial effects of this design are as follows: By incorporating a movable structure within the front engine compartment, the front bumper beam can be moved relative to the front bumper, altering its obstruction of the air intake grille. This design eliminates the need to increase the grille's footprint on the front bumper; simply moving the front bumper beam reduces its obstruction, improving grille area utilization. This satisfies the air intake area requirements for cooling the thermal management module during extreme operating conditions, when the engine and powertrain temperatures rise sharply. Furthermore, the movement of the front bumper relative to the front bumper alters its obstruction of the grille. In summer, under extreme operating conditions requiring a larger heat dissipation area, the movement reduces grille obstruction, increasing the heat dissipation area. Conversely, in winter, under extreme operating conditions requiring powertrain heat preservation, the movement increases grille obstruction, reducing the entry of cold air. This better meets the vehicle's air intake area requirements under different operating conditions.
[0008] In one embodiment of the present invention, the moving mechanism includes a first moving component and a second moving component that are spaced apart along the length of the front anti-collision beam; a first longitudinal beam and a second longitudinal beam are provided in the front engine compartment, the first moving component is movably connected to the first longitudinal beam, and the second moving component is movably connected to the second longitudinal beam.
[0009] The beneficial effects of this design are as follows: It creates movable support relationships at both ends of the front bumper beam along its length. This not only improves the smoothness of the front bumper beam's vertical movement, reducing the occurrence of jamming, but also enhances the timeliness and accuracy of its vertical movement. Furthermore, it improves the stress conditions between the moving mechanism and the front bumper beam, reducing the probability of malfunctions in the moving mechanism.
[0010] In one embodiment of the present invention, the first movable component and the second movable component are symmetrically arranged at both ends of the front anti-collision beam along its length.
[0011] The advantages of this arrangement are: symmetrically positioning the first and second moving components at both ends of the front bumper beam along its length simplifies the overall structural design of the moving structure, simplifies the installation and processing, and facilitates the positioning and installation of the first and second moving components on the front bumper beam, thus ensuring the smooth vertical movement of the front bumper beam.
[0012] In one embodiment of the present invention, both the first moving component and the second moving component are disposed in the area between the first longitudinal beam and the second longitudinal beam.
[0013] The beneficial effects of this configuration are as follows: When the two sides of the vehicle body are subjected to accidental impact or collision, the first longitudinal beam can provide better protection for the first moving component, and the second longitudinal beam can provide better protection for the second moving component. This reduces the probability of collision damage to the first and second moving components and better protects the integrity of the moving mechanism.
[0014] In one embodiment of the present invention, the first moving component includes a drive motor, a turbine, and a worm gear. The drive motor is fixedly connected to the front anti-collision beam, the output shaft of the drive motor is fixedly connected to the turbine, the worm gear is rotatably connected to the first longitudinal beam, and the turbine gear meshes with the worm gear.
[0015] The advantages of this configuration are: because the worm gear structure is relatively compact, this configuration can save the installation space occupied by the first moving component in the front engine compartment, and the worm gear transmission is relatively smooth with less noise, which is more conducive to the noise reduction design of the vehicle.
[0016] In one embodiment of this utility model, the moving mechanism further includes a temperature sensor to detect the operating temperature of the vehicle thermal management module.
[0017] The beneficial effects of this setup are: by setting up a temperature sensor, the operating temperature of the thermal management module can be obtained in real time. The drive motor can use the operating temperature of the thermal management module detected by the temperature sensor to adjust the position of the front bumper beam in real time, which helps the thermal management module to enter the optimal working state in a shorter time.
[0018] In one embodiment of the present invention, the first moving component further includes a motor connecting seat, which is fixedly connected to the front anti-collision beam and has an accommodating space; the drive motor is fixedly connected to the motor connecting seat, and the worm gear and the worm are engaged within the accommodating space.
[0019] The beneficial effects of this design are as follows: by providing a accommodating space on the motor connector and allowing the worm and turbine to mesh within the accommodating space, this design can provide a certain degree of protection for the meshing position of the worm and turbine, which helps to reduce the probability of meshing failure in the worm and turbine.
[0020] In one embodiment of the present invention, the first moving component further includes a connector, which is fixedly connected to the first longitudinal beam; a worm gear is rotatably connected to the connector, and the side of the connector away from the worm gear is slidably connected to the motor mounting base via a guide component.
[0021] The beneficial effects of this design are as follows: By setting a guide component between the connector and the motor connector, the guide component can guide the front bumper beam during its up-and-down movement, reducing jamming and skewing during the movement. This improves the stability and smoothness of the front bumper beam's up-and-down movement, ensuring the timeliness and accuracy of the front bumper beam's position adjustment.
[0022] In one embodiment of this utility model, the projection of the connector is located within the accommodating space along the height direction of the vehicle body.
[0023] The advantages of this design are as follows: This design allows for a more compact connection between the connector and the motor mounting bracket, reducing the installation space required in the front engine compartment. Simultaneously, this design results in a larger extension of the accommodating space along the length of the front bumper beam, thus creating a larger contact area between the motor mounting bracket and the front bumper beam, which improves the connection stability between them.
[0024] In one embodiment of the present invention, the guide assembly includes a guide groove and a guide block that are slidably connected to each other, one of which is disposed on the connector and the other is disposed on the motor connector.
[0025] The advantages of this design are: by setting guide grooves and guide blocks, not only can the movement between the connector and the motor connector be guided, but the guide structure also has fewer parts and is easier to form and process, thus helping to reduce the production and manufacturing cost of the moving structure.
[0026] In one embodiment of this utility model, the connector includes a hollow cavity.
[0027] The advantages of this design are as follows: because the connector includes a hollow cavity, its weight can be reduced, which is beneficial for lightweight vehicle design. At the same time, the hollow cavity structure can provide good supporting rigidity while maintaining lightweight design, which is beneficial for maintaining the vertical displacement accuracy between the connector and the motor mounting bracket.
[0028] In one embodiment of this utility model, a guide groove is provided on the connector, and a guide block is provided on the motor connector. The guide block enters the hollow cavity from the guide groove and stops at the side wall of the connector.
[0029] The advantages of this design are: This design allows part of the guide block to be housed within the hollow cavity, resulting in a more compact structure between the guide block and the guide groove, and reducing the installation space occupied by the guide assembly along the length of the front bumper beam.
[0030] In one embodiment of this utility model, the guide block and the motor connecting seat are integrally formed and connected.
[0031] The advantages of this design are as follows: By integrally molding the guide block and the motor connector, the assembly process between the guide block and the motor connector is eliminated, improving installation efficiency. Simultaneously, it enhances the connection strength between the guide block and the motor connector, further improving the stability of the transmission between the connector and the motor connector, and reducing the probability of operational failures.
[0032] In one embodiment of this utility model, the side of the connector facing the front anti-collision beam is slidably connected to the wall of the motor connector seat.
[0033] The beneficial effects of this design are as follows: by making the connector slide against the wall of the motor mounting bracket on the side facing the front bumper beam, the vertical movement between the connector and the motor mounting bracket can be further guided, thereby improving the stability of the front bumper beam's vertical movement.
[0034] In a second aspect, this utility model provides a vehicle that includes the body structure of any of the above embodiments. Attached Figure Description

[0046] Please see Figures 1 to 5This utility model provides a vehicle body structure 100 and a vehicle. The vehicle body structure 100, by incorporating a movable structure, allows the front bumper beam 130 to move within the front engine compartment 111, thereby altering the obstruction of the air intake grille 121 by the front bumper beam 130. This eliminates the need to increase the opening area of the air intake grille 121 on the front bumper 120; simply moving the position of the front bumper beam 130 reduces its obstruction of the air intake grille 121, improving the area utilization of the air intake grille 121. This, in turn, meets the air intake area requirements for cooling the thermal management module 170 when the vehicle is under extreme operating conditions and the engine and powertrain temperatures rise sharply.
[0047] Please see Figure 1 and Figure 2 The vehicle body structure 100 provided by this utility model includes: a front engine compartment 111, a front bumper 120, a front anti-collision beam 130, and a moving mechanism 140.
[0048] Please see Figure 1 and Figure 2The vehicle body structure 100 includes a main body 110, with a front engine compartment 111 located at the end of the main body 110 near the front of the vehicle. The front engine compartment 111 typically houses a thermal management module 170, a battery module, a motor drive system, and a motor control system. The specific structure of the front engine compartment 111 can be referenced from the structure of the front engine compartment 111 in existing vehicles, and will not be elaborated here. A front bumper 120 is mounted at the front end of the main body 110 to protect the front engine compartment 111. The front bumper 120 has an air intake grille 121. The front bumper 120 generally includes several conventionally configured components such as an outer bumper panel 122, an inner bumper panel, and a bumper bracket. The front bumper 120 is fixedly connected to the main body 110 using connecting bolts and clips. The outer bumper panel 122 is located at the very front of the main body 110, and the air intake grille 121 is mounted on the outer bumper panel 122. The air intake grille 121 communicates with the front engine compartment 111 to allow air to enter and exit the front engine compartment 111 for cooling the thermal management module 170. The air intake grille 121 can be directly formed on the outer bumper panel 122, i.e., integrally molded with the outer bumper panel 122. Alternatively, the air intake grille 121 can be separately formed and then fixed to the outer bumper panel 122 by snap-fit or bolts. The air intake grille 121 can extend linearly along the width direction of the vehicle body 110, or it can extend obliquely along the width direction of the vehicle body 110, depending on the vehicle's design requirements. One or multiple air intake grilles 121 can be provided. Multiple air intake grilles 121 can be arranged vertically along the height direction of the vehicle body 110, or they can be spaced apart along the width direction of the vehicle body 110. The air intake grille 121 can be located at the lower part of the outer bumper panel 122, or it can be located near the center, etc. In the actual design process, the number and location of the air intake grille 121 need to be determined based on various parameters such as the overall structural design and functional requirements of the vehicle.
[0049] Please see Figure 1 and Figure 2The front bumper beam 130 is movably disposed within the front engine compartment 111 and located on the side near the air intake grille 121, that is, the front bumper beam 130 is located between the air intake grille 121 and the thermal management module 170 within the front engine compartment 111. The front bumper beam 130 extends along the width direction of the vehicle body 110. In the width direction of the vehicle body 110, the length of the front bumper beam 130 can cover the length of the air intake grille 121 or be less than the length of the air intake grille 121, etc., and this embodiment does not limit this. A moving mechanism 140 is disposed within the front engine compartment 111, and the moving mechanism 140 drives the front bumper beam 130 to move up and down relative to the air intake grille 121 to change the obstruction of the air intake grille 121 by the front bumper beam 130. It should be noted that in this embodiment, the obstruction of the air intake grille 121 by the front bumper beam 130 mainly refers to the obstruction formed by the front bumper beam 130 on the air intake grille 121 in the height direction of the vehicle body 110. The moving mechanism 140 can be any linear drive mechanism capable of moving the front bumper beam 130 up and down. In one embodiment, the moving mechanism 140 can be a cylinder, with the cylinder seat fixed to the vehicle body 110 and the piston connected to the front bumper beam 130. The cylinder extends and retracts up and down, causing the front bumper beam 130 to move up and down relative to the air intake grille 121. In another embodiment, the moving structure can also be a combination of a motor and a rack and pinion structure. The motor is fixedly connected to the vehicle body 110, and the output shaft of the motor is connected to the gear. The rack is fixedly connected to the front bumper beam 130, and the rack and gear mesh and drive along the vertical direction of the vehicle body 110. When the motor rotates, the rack and gear mesh, thereby causing the front bumper beam 130 to move up and down relative to the air intake grille 121.
[0050] By installing a movable structure within the front engine compartment 111, the front bumper beam 130 can be moved relative to the front bumper 120, thereby altering the obstruction of the air intake grille 121 by the front bumper beam 130. This design eliminates the need to increase the opening area of the air intake grille 121 on the front bumper 120; simply operating the movable structure to move the front bumper beam 130 reduces its obstruction of the air intake grille 121, improving the area utilization of the air intake grille 121. This satisfies the air intake area requirements for cooling the thermal management module 170 when the vehicle is under extreme operating conditions and the engine and powertrain temperatures rise sharply. Meanwhile, as the front bumper beam 130 moves relative to the front bumper 120, the obstruction of the front bumper beam 130 to the air intake grille 121 can be changed. This allows the bumper beam to move and reduce the obstruction of the air intake grille 121 to increase the heat dissipation area when a higher heat dissipation area is required under extreme summer conditions. Conversely, when the powertrain's residual heat needs to be kept warm under extreme winter conditions, the bumper beam can move and increase the obstruction of the air intake grille 121 to reduce the entry of cold air. This better meets the vehicle's air intake area requirements for the air intake grille 121 under different operating conditions.
[0051] Given the relatively long length of the front bumper beam 130, the smoothness of its movement during vertical motion needs to be considered. Optionally, please refer to [link to relevant documentation]. Figure 3 In one embodiment of this utility model, the moving mechanism 140 includes a first moving component 1401 and a second moving component 1402 spaced apart along the length of the front bumper beam 130. The first moving component 1401 and the second moving component 1402 can be moving joints of the same structure or moving joints of different structures. The first moving component 1401 and the second moving component 1402 are respectively disposed at both ends of the front bumper beam 130 along its length. The specific spacing between the first moving component 1401 and the second moving component 1402 is not limited, as long as it ensures that the front bumper beam 130 can move smoothly up and down. The vehicle body 110 includes a first longitudinal beam 112 and a second longitudinal beam 113, which are respectively disposed at both ends of the width of the vehicle body 110. The first longitudinal beam 112 and the second longitudinal beam 113 can be symmetrically or asymmetrically arranged, depending on the design requirements of the vehicle body 110. The first moving component 1401 is movably connected to the first longitudinal beam 112, and the second moving component 1402 is movably connected to the second longitudinal beam 113. The movable connection can be a sliding connection, a rolling connection, or the like. It should be noted that during the vertical movement of the front bumper beam 130, the first moving component 1401 and the second moving component 1402 need to operate synchronously to ensure synchronized movement at both ends of the front bumper beam 130 along its length, thus ensuring the smooth vertical movement of the front bumper beam 130.
[0052] This configuration allows for movable support relationships at both ends of the front bumper beam 130 along its length. This not only improves the smoothness of the front bumper beam 130's vertical movement, reducing the likelihood of jamming, but also enhances the timeliness and accuracy of its vertical movement. Furthermore, it improves the stress distribution between the moving mechanism 140 and the front bumper beam 130, reducing the probability of malfunctions in the moving mechanism 140.
[0053] Please see Figure 3In one embodiment of this utility model, the first moving component 1401 and the second moving component 1402 are symmetrically arranged at both ends of the front bumper beam 130 along its length, meaning that the first moving component 1401 and the second moving component 1402 are identical moving structures. For example, the first moving component 1401 and the second moving component 1402 can be the same cylinder moving structure; or the first moving component 1401 and the second moving component 1402 can also be the same combination structure of motor and gear rack, etc. Symmetrically arranging the first moving component 1401 and the second moving component 1402 at both ends of the front bumper beam 130 along its length simplifies the overall structural design of the moving structure, simplifies the installation and processing technology, and also facilitates the positioning and installation of the first moving component 1401 and the second moving component 1402 on the front bumper beam 130, which is more conducive to ensuring the smooth vertical operation of the front bumper beam 130.
[0054] While ensuring the front bumper beam 130 can operate stably up and down, the specific positions of the first moving component 1401 and the second moving component 1402 on the vehicle body 110 are not limited. However, preferably, in one embodiment of this utility model, please refer to... Figure 3 Along the width direction of the vehicle body 110, both the first moving component 1401 and the second moving component 1402 are disposed in the area between the first longitudinal beam 112 and the second longitudinal beam 113. Specifically, along the width direction of the vehicle body 110, the first moving component 1401 is located on the side of the first longitudinal beam 112 facing inwards towards the vehicle body 110, and the second moving component 1402 is located on the side of the second longitudinal beam 113 facing inwards towards the vehicle body 110. This arrangement allows the first longitudinal beam 112 to provide better protection for the first moving component 1401 and the second longitudinal beam 113 to provide better protection for the second moving component 1402 in the event of an accidental impact or collision on either side of the vehicle body 110 in the width direction. This reduces the probability of collision damage to both components and better protects the integrity of the moving mechanism 140.
[0055] Please see Figure 3 and Figure 4In one embodiment of this utility model, the first moving component 1401 includes a drive motor 141, a turbine 142, and a worm gear 143. The drive motor 141 is fixedly connected to the front bumper beam 130. The drive motor 141 can be directly fixedly connected to the front bumper beam 130, or it can be indirectly fixedly connected to the front bumper beam 130 through other connecting parts 146. The output shaft of the drive motor 141 is fixedly connected to the turbine 142. The fixed connection method can be any method that can achieve the fixed connection between the turbine 142 and the output shaft of the drive motor 141, such as key connection or expansion connection. The two ends of the worm gear 143 are rotatably connected to the first longitudinal beam 112 through slewing bearings. The axial direction of the worm gear 143 is consistent with the height direction of the vehicle body 110, and the worm gear 143 and the turbine 142 are correspondingly meshed. When the drive motor 141 rotates, it drives the turbine 142 to rotate synchronously. The rotation of the turbine 142 drives the worm gear 143 to rotate, and at the same time, the turbine 142 drives the drive motor 141 to move up and down along the axial direction of the worm gear 143, thereby realizing the up and down movement of the front bumper beam 130 within the front engine compartment 111. This configuration, due to the compact structure of the turbine 142 and worm gear 143, saves the installation space occupied by the first moving component 1401 within the front engine compartment 111. Furthermore, the eddy current worm gear 143 provides smoother transmission and lower noise, which is more conducive to vehicle noise reduction design.
[0056] Please see Figure 1 , Figure 2 and Figure 4In one embodiment of this utility model, the moving mechanism 140 further includes a temperature sensor 150, which is used to detect the operating temperature of the vehicle's thermal management module 170. The temperature sensor 150 is electrically connected to a controller, and the controller is electrically connected to the drive motor 141. The controller can be a vehicle controller or a controller for the drive motor itself, such as a motor PLC control module, etc., and this embodiment does not specifically limit it. The temperature sensor 150 transmits the detected operating temperature of the thermal management module 170 to the controller, and the controller controls the rotation direction of the drive motor 141 according to the received operating temperature, thereby controlling the raising or lowering of the position of the front bumper beam 130 to adjust the obstruction of the air intake grille 121 by the front bumper beam 130 accordingly. For example, when the vehicle is under extreme operating conditions and the engine and powertrain temperatures rise sharply, the temperature sensor 150 detects the temperature increase and transmits the detected temperature signal to the controller. The controller then controls the steering of the drive motor 141 based on the set temperature to control the movement direction of the front bumper beam 130, thereby reducing the obstruction of the air intake grille 121 by the front bumper beam 130, improving the effective utilization rate of the air intake grille 121 area, and increasing the cooling area of the thermal management module 170. Conversely, when the front engine compartment 111 needs to retain residual heat from the powertrain in winter, the temperature sensor 150 detects a drop in the operating temperature of the thermal management module 170 and transmits the detected temperature signal to the controller. The controller then controls the steering of the drive motor 141 based on the detected temperature to control the movement direction of the front bumper beam 130, thereby increasing the obstruction of the air intake grille 121 by the front bumper beam 130, reducing the speed at which cold air from outside enters the front engine compartment 111, and ensuring the normal operating temperature inside the front engine compartment 111. By setting temperature sensor 150 and controller, the front anti-collision position in the front engine compartment 111 can be automatically adjusted according to the working temperature of thermal management module 170. The adjustment is more timely and accurate, which is more conducive to enabling thermal management module 170 to enter the optimal working state in the shortest time.
[0057] Please see Figure 4 and Figure 5In one embodiment of this utility model, the first moving component 1401 further includes a motor connecting seat 144, which is fixedly connected to the front anti-collision beam 130. The fixed connection method can be welding, bolting, or other methods. Preferably, in this embodiment, the motor connecting seat 144 and the front anti-collision beam 130 are fixed by welding. The motor connecting seat 144 can be a sheet metal bending part, a profile welding part, an integral casting part, or other structures. Optionally, in this embodiment, the motor connecting seat 144 is a sheet metal bending part. The motor connecting seat 144 forms an accommodating space 145. The accommodating space 145 can be a structure with open ends, an open end, or a structure with closed ends at both ends. Optionally, in this embodiment, the accommodating space 145 is a structure with open ends, that is, along the height direction of the vehicle body 110, both the upper and lower ends of the accommodating space 145 are open.
[0058] The drive motor 141 is fixedly connected to the motor connector 144. The drive motor 141 can be located inside or outside the accommodating space 145. Optionally, in this embodiment, the drive motor 141 is located outside the accommodating space 145. This arrangement facilitates the disassembly and installation of the drive motor 141 and the motor connector 144, and also facilitates the maintenance of the drive motor 141. The meshing of the worm gear 142 and the worm 143 within the accommodating space 145 means that the worm gear 142 is always within the accommodating space 145. During the meshing transmission process of the worm gear 142 and the worm 143, the accommodating space 145 and the worm gear 142 remain relatively stationary. When the worm gear 142 moves up and down along the axial direction of the worm 143, the accommodating space 145 also moves up and down synchronously with the worm gear 142, thereby realizing the meshing of the worm gear 142 and the worm 143 within the accommodating space 145. By providing a receiving space 145 on the motor connector 144 and making the turbine 142 and worm 143 mesh within the receiving space 145, this arrangement can provide a certain degree of protection for the meshing position of the turbine 142 and worm 143, which helps to reduce the probability of meshing failure of the turbine 142 and worm 143.
[0059] Please see Figure 4 and Figure 5In one embodiment of this utility model, the first moving component 1401 further includes a connector 146, which can be a profile or a sheet metal bending component. One end of the connector 146 in the height direction is fixedly connected to the first longitudinal beam 112, and the fixed connection method can be welding, bolting, etc. The other end of the connector 146 in the height direction extends toward the motor connecting seat 144, and the worm gear 143 is rotatably connected to the connector 146 through a slewing bearing. Along the length direction of the front anti-collision beam 130, the side of the connector 146 away from the worm gear 143 is slidably connected to the motor connecting seat 144 through a guide component 160. The guide component 160 can be of various types, such as a slide rail slider structure, a slide groove and protrusion structure, a guide sleeve and guide post structure, or any structure that can guide the sliding connection between the connector 146 and the motor connecting seat 144. By setting a guide component 160 between the connector 146 and the motor connector 144, the guide component 160 can guide the front bumper beam 130 during its up-and-down movement, reducing jamming and skewing during the movement of the connector 146 and the motor connector 144. This improves the stability and smoothness of the up-and-down movement of the front bumper beam 130, ensuring the timeliness and accuracy of the position adjustment of the front bumper beam 130.
[0060] Please see Figure 5 In one embodiment of this utility model, along the height direction of the vehicle body 110, the projection of the connector 146 is located within the accommodating space 145, that is, along the length direction of the front bumper beam 130, the connector 146 is slidably connected to the motor connector 144 within the accommodating space 145. This arrangement allows for a more compact connection between the connector 146 and the motor connector 144, which helps reduce the installation space occupied in the front engine compartment 111. Simultaneously, this arrangement results in a larger extension dimension of the accommodating space 145 along the length direction of the front bumper beam 130, thus allowing the motor connector 144 to form a larger contact area with the front bumper beam 130, which helps improve the connection stability between the motor connector 144 and the front bumper beam 130.
[0061] Although the structure of the guide component 160 can be chosen in various ways, considering the design cost and structural complexity, preferably, in one embodiment of this utility model, please refer to... Figure 5The guide assembly 160 includes a guide groove 161 and a guide block 162 that are slidably connected to each other. The guide groove 161 is disposed on the connector 146, and the length direction of the guide groove 161 is consistent with the height direction of the vehicle body 110. One or more guide grooves 161 can be provided. The guide block 162 is disposed on the motor connector 144, and the position of the guide block 162 corresponds to the position of the guide groove 161, that is, the guide block 162 is inserted into the guide groove 161 and slides up and down along the guide groove 161. One or more guide blocks 162 can be provided; one guide groove 161 can correspond to one guide block 162 or multiple guide blocks 162, depending on meeting the guiding requirements between the connector 146 and the motor mounting base. The guide block 162 can be a T-shaped block, a V-shaped block, or other structures. Correspondingly, the shape of the guide groove 161 changes with the shape of the guide block 162 to match guide blocks 162 of different shapes. In other embodiments, the guide groove 161 may be provided on the motor connector 144, and the guide block 162 may be provided on the connector 146. The guide block 162 may slide in the guide groove 161. This arrangement may also play a guiding role when the connector 146 moves relative to the motor connector 144.
[0062] Optionally, please refer to Figure 5 In this embodiment, the guide groove 161 is a rectangular groove structure, and the guide block 162 is a T-shaped block structure. One end of the T-shaped block passes through the interior of the connector 146 and forms a stop with the inner wall of the connector 146. The other end of the T-shaped block passes through the guide groove 161 and is fixedly connected to the motor connector 144. The fixed connection can be achieved by integrally molding the T-shaped block and the motor connector 144, or by bolt fixing, etc. The T-shaped block slides up and down in the guide groove 161, thereby realizing the up and down movement of the motor connector 144 within the guide groove 161. By setting the guide groove 161 and the guide block 162, not only can the movement guidance between the connector 146 and the motor connector 144 be realized, but the guide structure also has fewer parts and is easier to form and process, thus helping to reduce the manufacturing cost of the moving structure.
[0063] Please see Figure 5In one embodiment of this utility model, the connector 146 includes a hollow cavity 147. The hollow cavity 147 can extend throughout the entire length of the connector 146, or it can be located only in a section along the length of the connector 146. There are various ways to form the hollow cavity 147 on the connector 146, such as when the connector 146 is cast, or when the connector 146 is spliced and welded together. Preferably, in this embodiment, the connector 146 is a rectangular tube structure. Since rectangular tubes are a commonly used profile structure, they have a wide range of specifications, making selection convenient and reducing the procurement cycle. Because the connector 146 includes a hollow cavity 147, the weight of the connector 146 can be reduced, which is beneficial for lightweight vehicle design. At the same time, the hollow cavity 147 structure can provide good supporting rigidity while maintaining lightweight design, which is beneficial for maintaining the vertical displacement accuracy between the connector 146 and the motor connector 144.
[0064] To improve the compactness of the guide assembly 160 structure, preferably, please refer to Figure 5 In one embodiment of this utility model, the connector 146 is a rectangular tube structure, and a hollow cavity 147 is formed inside the connector 146. A guide groove 161 is disposed on any side wall of the connector 146, extending along the length of the connector 146. Optionally, in this embodiment, the guide groove 161 on the connector 146 is positioned opposite to the worm gear 143 on the connector 146, that is, the guide groove 161 and the worm gear 143 are respectively disposed on opposite side walls of the connector 146. This arrangement facilitates the installation of the guide block 162 on the motor connector 144 and reduces the probability of interference between the guide block 162 and the front anti-collision beam 130 or the worm gear 143.
[0065] The cross-section of the guide groove 161 can be any cross-sectional shape that matches the guide block 162, such as a rectangular cross-section or a V-section. Optionally, in this embodiment, please refer to... Figure 5The guide groove 161 has a rectangular cross-section. One side wall of the motor connector 144 abuts against the side wall of the connector 146 where the guide groove 161 is located. One end of the guide block 162 is fixedly connected to the wall of the motor connector 144 facing the guide groove 161, and the other end of the guide block 162 extends into the hollow cavity 147 and stops at the side wall of the connector 146, thereby allowing the side wall of the connector 146 to slide and engage between the guide block 162 and the wall of the motor connector 144, thus providing better guidance when the connector 146 and the motor connector 144 move up and down. This arrangement allows part of the guide block 162 to be housed within the hollow cavity 147, making the structure between the guide block 162 and the guide groove 161 more compact and reducing the installation space occupied by the guide assembly 160 along the length of the front bumper beam 130. It should be noted that the specific shape and structure of the guide block 162 are not limited. Preferably, in this embodiment, the guide block 162 is a T-shaped block structure. This design facilitates the processing of the guide block 162, and at the same time, a relatively stable and reliable guiding relationship can be formed between the T-shaped block and the guide groove 161.
[0066] The guide block 162 and the motor connector 144 can be connected by various methods such as bolt fixing or welding fixing. Optionally, in one embodiment of this utility model, please refer to... Figure 5 The guide block 162 is integrally formed and connected to the motor connecting seat 144. The guide block 162 can be integrally cast or integrally forged. By integrally forming the guide block 162 and the motor connecting seat 144, the assembly process between the guide block 162 and the motor connecting seat 144 can be saved, improving installation efficiency. At the same time, it also increases the connection strength between the guide block 162 and the motor connecting seat 144, further improving the transmission stability between the connector 146 and the motor connecting seat 144, and reducing the probability of operational failures.
[0067] To further improve the smoothness of vertical movement between the connector 146 and the motor connector 144, preferably, in one embodiment of this utility model, please refer to... Figure 5The connector 146 is slidably connected to the wall of the motor connector 144 on the side facing the front bumper beam 130. Specifically, the motor connector 144 includes a first mounting portion 1441 and a second mounting portion 1442 that are perpendicular to each other. The first mounting portion 1441 is connected to a guide block 162, and the second mounting portion 1442 is fixedly connected to the front bumper beam 130. The connector 146 includes a first sidewall 1461 and a second sidewall 1462 that are perpendicular to each other. A guide groove 161 is formed in the first sidewall 1461, and the first sidewall 1461 is slidably connected to the first mounting portion 1441 by the engagement of the guide block 162 with the guide groove 161. The second sidewall 1462 is slidably connected to the side of the second mounting portion 1442 that is away from the front bumper beam 130. By making the side of the connector 146 facing the front bumper beam 130 slide in connection with the wall of the motor connector 144, the vertical movement between the connector 146 and the motor connector 144 can be further guided, thereby further improving the stability of the vertical movement of the front bumper beam 130.
[0068] This utility model also provides a vehicle that includes the body structure 100 described in the above embodiments. The vehicle may also include conventional components found in existing vehicles, such as a suspension system, drive system, braking system, and electrical system. These conventional components can be designed according to existing technical solutions, and therefore will not be described in detail here, nor will they be considered limiting. Since this vehicle uses the body structure 100 described in the above embodiments, it at least possesses the beneficial effects brought about by the body structure 100 described in the above embodiments, which will not be elaborated upon further here.
[0069] The vehicle body structure of this utility model includes a movable structure within the front engine compartment. This movable structure drives the front bumper beam to move relative to the front bumper, thereby altering the obstruction of the air intake grille by the front bumper beam. This design eliminates the need to increase the area of the air intake grille on the front bumper; simply moving the movable structure to move the front bumper beam reduces its obstruction, improving the grille's area utilization. This satisfies the air intake area requirements for cooling the thermal management module when the vehicle is under extreme operating conditions, particularly when the engine and powertrain temperatures rise sharply. Furthermore, because the front bumper beam moves relative to the front bumper, it alters its obstruction of the air intake grille. This allows for adjustments during summer extreme operating conditions when a higher heat dissipation area is needed; conversely, during winter extreme operating conditions when powertrain waste heat needs to be preserved, the movement of the bumper beam increases its obstruction of the air intake grille, reducing the entry of cold air. This better meets the vehicle's air intake area requirements under different operating conditions. Therefore, this utility model effectively overcomes some practical problems in the prior art, thus having high utilization value and significance.
[0070] 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.
