DETAILED DESCRIPTION
[0040] An embodiment of the present application provides a front cover assembly 10 for a vehicle.
[0041] See also Figures 1 to 8 The front cover assembly 10 includes a front cover inner panel 12 , a front cover outer panel 11 and a rigidity adjustment mechanism 13 .
[0042] See also Figures 1 to 3 The front cover inner plate 12 is connected to the top of the front cover inner plate 12 , and a cavity 10 a is formed between the front cover inner plate 12 and the front cover outer plate 11 .
[0043] The edges of the front cover outer plate 11 and the front cover inner plate 12 can be fixed by hemming and folding adhesive bonding. The cavity 10a formed between the front cover outer plate 11 and the front cover inner plate 12 can cause the front cover outer plate 11 to deform and provide installation space for the rigidity adjustment mechanism 13.
[0044] It should be noted that the front cover outer panel 11 and the front cover inner panel 12 in the embodiment of the present application adopt the front cover outer panel 11 and the front cover inner panel 12 originally installed on the existing vehicle, and the structure and installation method of the front cover outer panel 11 and the front cover inner panel 12 do not change, which is convenient for production and will not affect the overall shape of the vehicle.
[0045] It is understandable that the front hood inner panel has a high rigidity and is not easily deformed, while the front hood outer panel is thin and is prone to being soft when pressed or rebounding, which affects the quality of the vehicle and there is no reliable after-sales maintenance method. In the related technology, a bracket structure is set in the cavity to support the front hood outer panel, but the design of the bracket structure can only increase the rigidity of the front hood outer panel and cannot be adjusted. If there are defects in the design of the bracket structure, a lot of cost and time are required to rectify and optimize it. It is impossible to adaptively adjust the rigidity of the front hood outer panel during the production and assembly of the front hood outer panel and the after-sales process, making the vehicle model design difficult and the after-sales cost high.
[0046] Therefore, in the embodiment of the present application, a rigidity adjustment mechanism 13 is provided, through which the front cover outer panel 11 is supported, and the supporting force of the front cover outer panel 11 can be adjusted. The rigidity of the front cover outer panel 11 is adjusted during the production and assembly process of the front cover assembly 10 so that the rigidity of the front cover outer panel 11 meets the target requirement, and the front cover outer panel 11 can also be assembled and adjusted for vehicles with soft or rebounding sound during after-sales service, thereby reducing after-sales costs.
[0047] See also Figures 3 to 8 The rigidity adjustment mechanism 13 includes a stroke adjustment mechanism, a support member 131 and an elastic member 132. The stroke adjustment mechanism is penetrated through the cavity 10a and connected to the front cover inner plate 12. The stroke adjustment mechanism is provided with a mounting cavity 135b. At least a portion of the support member 131 is disposed in the cavity 10a, one end of the support member 131 is connected to the front cover outer plate 11, and the other end is penetrated through the mounting cavity 135b. One end of the elastic member 132 abuts against the stroke adjustment mechanism, and the other end cooperates with the support member 131.
[0048] The stroke adjustment mechanism has an operating end 1341, which is located on the side of the front cover inner plate 12 away from the front cover outer plate 11. The operating end 1341 can drive at least part of the stroke adjustment mechanism to move relative to the support member 131 at least along the top and bottom directions under the action of external force, so as to adjust the elastic force transmitted from the elastic member 132 to the front cover outer plate 11 via the support member 131.
[0049] The support member 131 is connected to the front cover outer panel 11 and is disposed in the installation cavity 135b, that is, the rigidity adjustment mechanism 13 transmits the supporting force to the front cover outer panel 11 through the support member 131. Exemplarily, the support member 131 is a rigid member.
[0050] The support member 131 can be fixed relative to the front cover outer plate 11, that is, there is no relative movement between the support member 131 and the front cover outer plate 11. Of course, there is no relative movement between the support member 131 and the front cover inner plate 12 either.
[0051] The operating end 1341 is located on a side of the front cover inner plate 12 away from the front cover outer plate 11, that is, the operating end 1341 can be located outside the cavity 10a, and the operating end 1341 can be exposed on the outer surface of the front cover assembly 10. In this way, when the front cover outer plate 11 is adjusted during production and assembly or after-sales service is required, the operator can apply external force to the stroke adjustment mechanism through the operating end 1341, so that at least part of the stroke adjustment mechanism is displaced relative to the support member 131 at least along the top and bottom directions, thereby changing the elastic force of the elastic member 132, and then changing the supporting force transmitted from the support member 131 to the front cover outer plate 11, so as to adaptively adjust the rigidity of the front cover outer plate 11.
[0052] It should be noted that the external force may be the operating force of the operator's hand, or may be the force applied by the operator to the operating end 1341 through an operating tool.
[0053] At least part of the stroke adjustment mechanism moves relative to the support member 131 under the action of an external force. Here, part of the structure of the stroke adjustment mechanism may move relative to the support member 131, or the entire stroke adjustment mechanism may move relative to the support member 131. Exemplarily, the structure of the stroke adjustment mechanism used to connect with the front cover inner plate 12 is fixed relative to the front cover inner plate 12, that is, the part of the structure is fixed relative to the support member 131, and the rest of the structure of the stroke adjustment mechanism moves relative to the support member 131, the front cover inner plate 12, and the front cover outer plate 11.
[0054] It should be noted that the movement mode of at least part of the structure of the stroke adjustment mechanism relative to the support member 131 is not limited, and can be sliding, rotating, or a combination of the two, as long as it can at least generate displacement along the top and bottom directions. Here, at least generating displacement along the top and bottom directions means that it can only generate displacement along the top and bottom directions, or it can be a superposition of displacement along the top and bottom directions and displacement perpendicular to the top and bottom directions. The support member 131 is inserted into the mounting cavity 135b, which can provide a certain guiding effect for the movement of the stroke adjustment mechanism and increase the movement stability, so that the rigidity adjustment mechanism 13 as a whole provides rigid support for the front cover outer panel 11.
[0055] The elastic member 132 is disposed on the movement path of the stroke adjustment mechanism. One end of the elastic member 132 abuts against the stroke adjustment mechanism, and the other end cooperates with the support member 131. The elastic member 132 can be adaptively deformed under the movement of the stroke adjustment mechanism, and the elastic force of the elastic member 132 has at least a component force along the top-bottom direction, so that it is transmitted to the front cover outer panel 11 on the top side through the support member 131.
[0056] There is no limit to the cooperation mode between the elastic member 132 and the support member 131 , which can be abutment or a combination of abutment and sleeve. No limitation is made here, as long as the elastic force of the elastic member 132 can act on the support member 131 .
[0057] The front hood assembly 10 provided in the embodiment of the present application changes the relative position between at least part of the stroke adjustment mechanism and the support member 131 through the relative movement between the two, thereby changing the elastic force of the elastic member 132, and then adjusting the support force transmitted to the front hood outer panel 11 through the support member 131. In this way, the rigidity of the front hood outer panel 11 can be adjusted during the production and assembly process to adapt to the rigidity requirements of the increasingly thin front hood outer panel 11, reducing the difficulty and time of research and development of different models, and the front hood outer panel 11 can be assembled and adjusted in the after-sales process where it is soft or rebounds, reducing the after-sales cost. At the same time, the rigidity adjustment mechanism 13 of the embodiment of the present application can be used repeatedly and modularly produced as a separate module, suitable for a variety of vehicle models, with high versatility, and the position of the rigidity adjustment mechanism 13 can be flexibly arranged according to the vehicle shape, with few structural restrictions on the front hood outer panel 11 and the front hood inner panel 12.
[0058] For some examples, see Figures 3 to 5 The support member 131 includes a support end 1311, and the support member 131 is connected to the front cover outer panel 11 through the support end 1311. A glue groove 1311a is provided on the side of the support end 1311 facing the front cover outer panel 11. The rigidity adjustment mechanism 13 includes an adhesive 136, and the adhesive 136 is provided in the adhesive groove 1311a to connect the support member 131 and the front cover outer panel 11.
[0059] In this embodiment, the connection between the support member 131 and the front cover outer panel 11 is achieved by adhesive 136. In this way, the connection stability between the support member 131 and the front cover outer panel 11 is high, and no relative movement occurs between the support member 131 and the front cover outer panel 11. At the same time, it is also convenient for the support member 131 to transmit the supporting force to the front cover outer panel 11 and adjust the rigidity of the front cover outer panel 11.
[0060] In some embodiments, the other end of the elastic member 132 abuts against one end of the support member 131 close to the front cover inner plate 12. That is, in this embodiment, the entire elastic member 132 is located at the bottom side of the support member 131, and the support member 131 and the elastic member 132 are in abutment. In this embodiment, the size of the elastic member 132 can be small, which increases the compactness of the structure.
[0061] In some other embodiments, please refer to Figures 3 to 5 The other end of the elastic member 132 abuts against an end of the support member 131 away from the front cover inner panel 12 .
[0062] It can be understood that the end of the support member 131 away from the front cover inner plate 12 is the above-mentioned support end 1311.
[0063] In this embodiment, the dimensions of the elastic member 132 and the support member 131 along the top and bottom directions have an overlapping portion, so that the dimension of the elastic member 132 can be longer, increasing the stability of the arrangement of the elastic member 132. Of course, the elastic force of the elastic member 132 can directly act on the support end 1311, and then act on the front cover outer plate 11, reducing the transmission path. At the same time, the matching mode of the elastic member 132 and the support member 131 can be abutment, or a combination of abutment and sleeve, which is convenient for the arrangement of the elastic member 132.
[0064] For example, in some embodiments, please refer to Figures 3 to 5 The support member 131 includes a support end 1311 and a guide column 1312. The support member 131 is connected to the front cover outer panel 11 through the support end 1311. One end of the guide column 1312 is connected to the support end 1311, and the other end is passed through the installation cavity 135b. The elastic member 132 is sleeved on the outside of the guide column 1312 and abuts between the support end 1311 and the stroke adjustment mechanism.
[0065] For example, see Figure 3 and Figure 4 The elastic member 132 is sleeved on the outer side of the guide column 1312 , one end of the elastic member 132 abuts against the supporting end 1311 , and the other end is disposed in the mounting cavity 135 b .
[0066] It can be understood that the extension direction of the guide column 1312 can be the displacement direction generated by the stroke adjustment mechanism. The extension direction of the guide column 1312 can be the same as the top and bottom directions, or can be arranged at an acute angle to the top and bottom directions.
[0067] In this embodiment, the elastic member 132 and the support member 131 are matched in a manner that is a superposition of sleeve connection and abutment. The guide column 1312 can not only provide guidance for the movement of the stroke adjustment mechanism, but also increase the setting stability of the elastic member 132 and reduce the probability of accidental disengagement of the elastic member 132, so as to stably adjust the rigid support force of the rigid adjustment mechanism 13 on the front cover outer panel 11.
[0068] The specific structure of the elastic member 132 is not limited, for example, please refer to Figure 3 and Figure 4 , the elastic member 132 can be a spring.
[0069] It can be understood that along the top and bottom directions, the size of the support member 131 at the support end 1311 is larger than the size of the support member 131 at the guide column 1312, so that it can stably abut against the elastic member 132 to prevent the elastic member 132 from falling out. At the same time, it can also increase the area of the glue groove 1311a of the support end 1311 to facilitate the connection between the rigidity adjustment mechanism 13 and the front cover outer panel 11.
[0070] For some examples, see Figure 4 and Figure 8 The rigidity adjustment mechanism 13 includes a first gasket 137 , and the first gasket 137 is disposed between the elastic member 132 and the supporting end 1311 .
[0071] In this embodiment, the provision of the first gasket 137 can reduce the wear of the elastic member 132 on the support end 1311, extend the service life of the support member 131, and facilitate the support end 1311 to effectively transmit the rigid support force.
[0072] Exemplarily, the first gasket 137 may be a rigid member.
[0073] For some examples, see Figure 4 and Figure 8 The rigidity adjustment mechanism 13 includes a second gasket 138, and the second gasket 138 is arranged between the elastic member 132 and the stroke adjustment mechanism.
[0074] In this embodiment, the provision of the second gasket 138 can reduce the wear of the elastic member 132 on the stroke adjustment mechanism, extend the service life of the stroke adjustment mechanism, and increase the structural reliability of the rigidity adjustment mechanism 13 .
[0075] Exemplarily, the second gasket 138 may be a rigid member.
[0076] It is understood that in the embodiment where the other end of the elastic member 132 is disposed in the mounting cavity 135b, see Figure 8 A positioning structure 1352 may be provided in the installation cavity 135b, and the second gasket 138 may cooperate with the positioning structure 1352 to limit the second gasket 138, thereby stabilizing the position of the second gasket 138 in the installation cavity 135b, thereby facilitating the positioning of the elastic member 132.
[0077] In some embodiments, the support end 1311 is welded to the guide post 1312 .
[0078] Welding is a technique that uses heat to melt materials and then rejoin them to form a whole.
[0079] In this embodiment, the support end 1311 is welded with the guide post 1312, which can facilitate the coordination of the guide post 1312 with the stroke adjustment mechanism and the elastic member 132 during assembly, and then connect the guide post 1312 with the support end 1311, thereby increasing the convenience of assembly. At the same time, it is also convenient to set a limit (such as the limit end 1313 described below) on the side of the guide post 1312 away from the support end 1311 to reduce the probability of the guide post 1312 escaping from the installation cavity 135b, and also to limit the movement of the stroke adjustment mechanism. Of course, the welding of the support post and the guide post 1312 can also increase the overall structural strength of the support member 131, thereby facilitating the formation of a stable support.
[0080] The specific structure of the stroke adjustment mechanism is not limited.
[0081] For some examples, see Figures 3 to 8 The stroke adjustment mechanism includes a fixed seat 133 and a first adjusting member 134. The fixed seat 133 is connected to the front cover inner plate 12. There is no relative movement between the fixed seat 133 and the front cover inner plate 12. The fixed seat 133 has a hollow space 133a. One end of the first adjusting member 134 is inserted into the hollow space 133a and is movably connected to the fixed seat 133. The operating end 1341 is arranged on a side of the first adjusting member 134 away from the fixed seat 133. The first adjusting member 134 can move relative to the fixed seat 133 and the support member 131 under the action of external force. The elastic member 132 is located on the movable path of the first adjusting member 134.
[0082] The fixing seat 133 can be used as a base to provide installation support for the first adjustment member 134 . The fixing seat 133 is connected to the front cover inner plate 12 without relative movement, which can increase the setting stability of the fixing seat 133 and thus increase the rigid support stability of the rigid adjustment mechanism 13 .
[0083] The hollow space 133 a can provide a space for the first adjusting member 134 , the supporting member 131 and the elastic member 132 to penetrate therethrough, so as to facilitate the cooperation among the first adjusting member 134 , the supporting member 131 and the elastic member 132 .
[0084] The first adjusting member 134 is movably connected to the fixing seat 133 , so that the first adjusting member 134 can move relative to the fixing seat 133 , thereby adjusting the elastic force of the elastic member 132 .
[0085] In this embodiment, the cooperation between the first adjusting member 134 and the fixing seat 133 can achieve stable cooperation with the front cover inner plate 12, and at the same time, the movement of the first adjusting member 134 relative to the fixing seat 133 can achieve movement relative to the support member 131. The movement is simple and reliable and will not affect the front cover inner plate 12.
[0086] The movable connection method between the first adjusting member 134 and the fixing seat 133 is not limited.
[0087] For some examples, see Figures 3 to 8 The fixed seat 133 includes a first threaded segment 133b, and the first adjusting member 134 includes a second threaded segment 134a. The first threaded segment 133b and the second threaded segment 134a are threadedly matched to realize the connection between the first adjusting member 134 and the fixed seat 133. The operating end 1341 is used to drive the first adjusting member 134 to rotate so that the first adjusting member 134 has at least a linear displacement along the top and bottom directions during the rotation process.
[0088] Specifically, the first thread segment 133b may be formed on an inner sidewall of the hollow space 133a.
[0089] In this embodiment, the first thread segment 133b and the second thread segment 134a cooperate to realize the movable connection between the fixing seat 133 and the first adjusting member 134, and the connection method is simple. When it is necessary to increase the rigid support force of the front cover outer panel 11, it is only necessary to apply an external force to the operating end 1341 to rotate the first adjusting member 134 upward, so that the rigid support force of the front cover outer panel 11 can be gradually increased. In addition, the cooperation of the first thread segment 133b and the second thread segment 134a can also make the first adjusting member 134 stably maintain the adjusted position after movement, thereby increasing the rigid support stability of the front cover outer panel 11. The cooperation method of the fixing seat 133 and the first adjusting member 134 is simple, easy to operate, and has good stability.
[0090] It is understandable that the movement displacement of the first adjusting member 134 in the top-bottom direction after one rotation can be adjusted by adjusting the pitch of the first thread segment 133b and the second thread segment 134a.
[0091] In some embodiments, the rotation axis of the first adjusting member 134 is parallel to the top-bottom direction, or the angle between the rotation axis of the first adjusting member 134 and the top-bottom direction is an acute angle.
[0092] That is, the first adjusting member 134 can generate a linear displacement along the top-bottom direction by rotating, or can be tilted relative to the top-bottom direction to generate a partial displacement along the top-bottom direction. In this way, the rigidity adjusting mechanism 13 can be easily adapted to different installation environments, increasing the adaptability of the rigidity adjusting mechanism 13.
[0093] For example, see Figure 3 and Figure 4 , the rotation axis E of the first adjusting member 134 is set at an acute angle to the top and bottom directions.
[0094] For some examples, see Figures 3 to 8The stroke adjustment mechanism includes a second adjustment member 135. The first adjustment member 134 is open toward one side of the fixed seat 133 to form an open groove 134c. The second adjustment member 135 is inserted into the hollow space 133a and the open groove 134c to be connected with the first adjustment member 134. The second adjustment member 135 is formed into a hollow structure. The space within the second adjustment member 135 defines at least a portion of the installation cavity 135b.
[0095] Specifically, the support member 131 is disposed in the hollow space 133a and the installation cavity 135b to connect with the second adjustment member 135, and the second adjustment member 135 and the support member 131 can generate relative movement through the support member 131. The elastic member 132 abuts between the second adjustment member 135 and the support end 1311.
[0096] There is no relative movement between the second adjusting member 135 and the first adjusting member 134. That is, the second adjusting member 135 is relatively fixed to the first adjusting member 134. In this embodiment, the first adjusting member 134 and the second adjusting member 135 can be an integrated structure or a split structure. The second adjusting member 135 is docked with the support member 131, and moves relative to the support member 131 under the drive of the first adjusting member 134, thereby changing the relative position between the second adjusting member 135 and the support end 1311, adjusting the elastic force of the elastic member 132, and the movement is reliable.
[0097] In another embodiment, the first adjusting member 134 and the second adjusting member 135 move relative to each other.
[0098] That is, in this embodiment, the first adjusting member 134 and the second adjusting member 135 can produce relative movement, that is, the first adjusting member 134 and the second adjusting member 135 are movably connected. In this way, the movement displacement of the stroke adjustment mechanism relative to the support member 131 can be increased or reduced through the movement of the first adjusting member 134 relative to the fixed seat 133 and the movement of the second adjusting member 135 relative to the first adjusting member 134, thereby increasing or decreasing the adjustment sensitivity of the rigidity adjustment mechanism 13 to adapt to different adjustment requirements.
[0099] For some examples, see Figures 3 to 8 The support member 131 includes a limit end 1313, which is arranged on a side of the support member 131 away from the front cover outer panel 11. The limit end 1313 is located outside the installation cavity 135b and inside the open groove 134c. The limit end 1313 can be detachably abutted against an end of the second adjustment member 135 away from the front cover outer panel 11 to limit the movement displacement of the first adjustment member 134 along the top and bottom directions.
[0100] In this embodiment, the setting of the limit end 1313 can limit the movement of the first adjusting member 134 by abutting against the second adjusting member 135 away from the front cover outer panel 11, so that the movement of the first adjusting member 134 is within a safe and stable range, reducing damage to the elastic member 132 and reducing excessive or insufficient support for the front cover outer panel 11.
[0101] When the first adjusting member 134 is rotated until the second adjusting member 135 abuts against the limit end 1313, when the user rotates the first adjusting member 134 in the current direction, it will be stopped by the limit end 1313 and cannot continue to rotate in the current direction but can only rotate in the opposite direction.
[0102] For some examples, see Figures 3 to 8 The second adjusting member 135 is provided with a limiting structure 1351, and the limiting structure 1351 is provided on the outside of the open groove 134c. The outer wall of the second adjusting member 135 protrudes outward to form the limiting structure 1351. The limiting structure 1351 is used to be inseparable from the top end of the first adjusting member 134 to limit the movement displacement of the first adjusting member 134 along the top-to-bottom direction.
[0103] In this embodiment, the setting of the limiting structure 1351 can detachably dock with the top end of the first adjusting member 134 to limit the movement of the first adjusting member 134, so that the movement of the first adjusting member 134 is within a safe and stable range, reducing damage to the elastic member 132 and reducing excessive or insufficient support for the front cover outer panel 11.
[0104] Exemplarily, the setting of the limiting structure 1351 can limit the upward rotation of the first adjusting member 134, and the setting of the limiting end 1313 can limit the downward rotation of the first adjusting member 134, so that the movement displacement of the first adjusting member 134 is kept within a safe range that can effectively support the front cover outer panel 11, thereby increasing the structural reliability of the rigid adjustment mechanism 13.
[0105] The connection method between the first adjusting member 134 and the second adjusting member 135 is not limited.
[0106] For some examples, see Figures 3 to 8 The first adjusting member 134 includes a third thread segment 134b, which is formed in the open groove 134c. The second adjusting member 135 includes a fourth thread segment 135a. The third thread segment 134b and the fourth thread segment 135a are threadedly matched to achieve the connection between the first adjusting member 134 and the second adjusting member 135.
[0107] Specifically, the first thread segment 133b is an internal thread, the second thread segment 134a is an external thread, the third thread segment 134b is an internal thread, and the fourth thread segment 135a is an external thread.
[0108] In this embodiment, the first adjusting member 134 and the second adjusting member 135 are movably connected by the cooperation of the third thread segment 134b and the fourth thread segment 135a. The connection method is simple. When it is necessary to increase the rigid support force of the front cover outer panel 11, it is only necessary to apply an external force to the operating end 1341 to rotate the first adjusting member 134 upward, thereby driving the second adjusting member 135 to move. The second adjusting member 135 increases or decreases the actual movement displacement relative to the support member 131, thereby adjusting the support force on the front cover outer panel 11. In this way, the rigidity of the rigidity adjustment mechanism 13 is more adjustable, and the adjustment sensitivity can be increased or decreased according to needs.
[0109] In this embodiment, the third thread segment 134b and the fourth thread segment 135a cooperate to realize the movable connection between the first adjusting member 134 and the second adjusting member 135. The connection method is simple, easy to operate, and has good stability.
[0110] It is understandable that the movement displacement of the second adjusting member 135 relative to the supporting member 131 when the first adjusting member 134 rotates one circle can be adjusted by adjusting the pitch of the second thread segment 134a and the third thread segment 134b.
[0111] In some embodiments, the second thread segment 134a and the third thread segment 134b have opposite thread directions.
[0112] In this way, the movement directions of the first adjusting member 134 and the second adjusting member 135 are opposite, and the movement displacement of the second adjusting member 135 relative to the supporting member 131 can be reduced, which is convenient for realizing micro-adjustment of the supporting force. The stiffness of the front cover outer panel 11 will not change suddenly, thereby increasing the adjustment reliability and the appearance reliability of the front cover outer panel 11.
[0113] In some embodiments, the pitch of the second thread segment 134a is greater than the pitch of the third thread segment 134b. In this way, the adjustment sensitivity of the rigidity adjustment mechanism 13 is reduced, the rigidity support force of the front cover outer panel 11 is finely adjusted, and the adjustment reliability is increased.
[0114] For example, the ratio of the pitch of the second thread segment 134a to the pitch of the third thread segment 134b may be 1.5, 2, 2.2, 2.4, 2.5, 2.7, 3, 3.3, 3.5, 4, etc. Taking the pitch ratio of the second thread segment 134a to the third thread segment 134b as 2 as an example, if the first adjusting member 134 rotates one circle and moves upward by 2 mm, the second adjusting member 135 actually moves upward by 1 mm.
[0115] For some examples, see Figures 3 to 5Part of the outer wall of the fixing seat 133 is recessed inward to form a clamping portion 133c. The front cover inner plate 12 is provided with a through mounting hole 12a. Part of the fixing seat 133 is passed through the mounting hole 12a and is arranged in the cavity 10a. The other part is clamped with the hole wall of the mounting hole 12a through the clamping portion 133c and abuts against the bottom wall of the front cover inner plate 12.
[0116] In this embodiment, the docking of the fixing seat 133 and the front cover inner plate 12 is achieved by snapping. While achieving assembly, the front cover inner plate 12 can be avoided to reduce damage to the front cover inner plate 12 and reduce installation marks on the front cover inner plate 12. At the same time, the connection method is simple and reliable, reducing the difficulty of assembly.
[0117] Exemplarily, the fixing seat 133 may be a plastic part.
[0118] For some examples, see Figures 3 to 5 The fixing seat 133 is formed with a notch 133d, and the notch 133d penetrates the side wall of the hollow space 133a, so that the fixing seat 133 can be deformed when docking with the mounting hole 12a.
[0119] In this embodiment, the provision of the notch 133d allows the fixing seat 133 to at least partially shrink inward when docking with the front cover inner plate 12, so as to adapt to the manufacturing tolerance of the mounting hole 12a of the front cover inner plate 12, thereby increasing the docking reliability between the fixing seat 133 and the front cover inner plate 12.
[0120] The following is a brief description of the assembly process of the rigidity adjustment mechanism 13 and the front cover inner panel 12 and the front cover outer panel 11 according to an embodiment of the present application.
[0121] First, the second adjusting member 135 is sleeved from top to bottom on the outer side of the guide column 1312, the second gasket 138 is matched with the positioning structure 1352 in the installation cavity 135b, and then the elastic member 132 is sleeved outside the guide column 1312, the first gasket 137 is sleeved on the guide column 1312, and then the support end 1311 is welded with the guide column 1312, so that the second adjusting member 135, the support member 131 and the elastic member 132 form a pre-assembled whole. Then, the first adjusting member 134 is inserted into the hollow space 133a from bottom to top, and the first thread segment 133b is threadedly matched with the second thread segment 134a, so that the first adjusting member 134 and the fixing seat 133 form a pre-assembled whole, and then the two pre-assembled wholes are matched, and the third thread segment 134b and the fourth thread segment 135a are threadedly matched, so that the assembly of the rigid adjustment mechanism 13 is completed.
[0122] Finally, adhesive 136 is applied to the adhesive groove 1311a of the support end 1311, and the rigid adjustment mechanism 13 is installed into the cavity 10a from bottom to top, so that the clamping portion 133c of the fixing seat 133 is clamped and matched with the mounting hole 12a of the front cover inner plate 12, and the adhesive 136 connects the support end 1311 and the front cover outer plate 11.
