Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically to a main frame for mounting a vehicle's sub-instrument panel, a sub-instrument panel assembly, and a vehicle. Background Technology

[0002] In the automotive industry, the sub-instrument panel, as an important interior component, is typically used to provide shelter and mounting support for structural components such as air conditioning, gear shifting mechanisms, mechanical handbrakes, and air ducts, while also fulfilling functional requirements such as air vents, elbow rests, and storage. The main frame is the core supporting component of the sub-instrument panel. Most existing main frames are fixed-size structures. When it is necessary to adapt the sub-instrument panel to different vehicle configurations, a separate mold needs to be designed to manufacture the corresponding frame, resulting in high development and manufacturing costs. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention provides a main frame for mounting a vehicle sub-instrument panel, a sub-instrument panel assembly, and a vehicle, so as to improve the shortcomings of the existing main frame with high development and manufacturing costs.

[0004] To achieve the above and other related objectives, the first aspect of this utility model provides a main frame for mounting a vehicle sub-instrument panel. The main frame includes a main frame body, which has at least one connecting end configured to be detachably connected to an extension frame. The main frame can independently adapt to a sub-instrument panel of one specification. When the connecting end is connected to the extension frame, the extension structure formed by the combination of the main frame and the extension frame can adapt to a sub-instrument panel of another specification.

[0005] The advantages of this design are as follows: By setting connecting ends on the main frame and configuring these ends for detachable connection with the extension frame, the main frame can independently adapt to one size of sub-instrument panel. When the connecting ends are connected to the extension frame, the combined structure of the main frame and the extension frame can adapt to another size of sub-instrument panel. This design allows for changes in frame size by changing the dimensions of the extension frame connected to the main frame or adjusting the combination method between the extension frame and the main frame, thus adapting to different sizes of sub-instrument panels. Because the main frame itself is versatile, only the design of the extension frame needs to be changed, reducing the investment in large molds and tooling. This not only reduces production costs but also improves production efficiency. Furthermore, this modular design makes the design and manufacturing of the frame more flexible. When developing new models or adjusting sub-instrument panel specifications, there is no need for large-scale modifications to the main frame; only the extension frame needs to be adjusted to meet the new requirements. This flexibility greatly shortens the development cycle and improves production efficiency.

[0006] In one embodiment of this utility model, the main frame is provided with a first receiving cavity, the extended frame is provided with a second receiving cavity, and the first receiving cavity and the second receiving cavity are independently arranged.

[0007] The advantages of this design are as follows: By incorporating a second accommodating cavity into the extended frame, when connected to the main frame, the extended frame not only lengthens the main frame but also increases the overall accommodating space of the sub-instrument panel, allowing for better matching of the sub-instrument panel configuration requirements of different vehicle models. Furthermore, since the first and second accommodating cavities are independently configured, the first accommodating cavity can be preserved intact when the main frame is used alone, thus better meeting its own storage space requirements.

[0008] In one embodiment of the present invention, the connecting end is provided with a plurality of spaced first connecting parts, and the expansion frame is provided with a plurality of spaced second connecting parts. Each first connecting part corresponds to a second connecting part. When the connecting end is connected to the expansion frame, the first connecting parts and the second connecting parts press against each other and are fixedly connected by fasteners.

[0009] The advantages of this design are as follows: By incorporating multiple first and second connecting parts, multiple spaced local contact surfaces are formed when the first and second connecting parts abut and press against each other. This improves contact stability, ensuring a more stable and reliable connection between the extended frame and the main frame after fastener fixation, reducing the probability of loosening or displacement at the connection point. Furthermore, the fastener fixation between the first and second connecting parts provides a stable and reliable connection method with a simple structure and low cost.

[0010] In one embodiment of the present invention, the connecting surface formed between the first connecting portion and the second connecting portion extends at least partially to the outer side of the expansion frame and the main frame body in the width direction.

[0011] The advantages of this design are as follows: This design allows for a fixed connection between the first and second accommodating cavities outside the first and second accommodating cavities. This not only makes the connection between the main frame and the expansion frame more stable and reliable, but also allows the connection position to avoid the first and second accommodating cavities. Therefore, it is convenient to reserve connection holes on the connection end without damaging the walls of the first and second accommodating cavities.

[0012] In one embodiment of this utility model, a positioning structure is provided between the main frame and the extension frame to position the connection position between the main frame and the extension frame when the connecting end is connected to the extension frame.

[0013] The beneficial effects of this design are as follows: By setting up a positioning structure, not only can the accuracy of the connection position between the main frame and the extension frame be improved, but the alignment efficiency between the first connection part and the second connection part can also be improved, which in turn helps to improve the assembly connection efficiency between the main frame and the extension frame.

[0014] In one embodiment of the present invention, the positioning structure includes a connector and a positioning hole adapted to the connector. The connector includes multiple circumferential sidewalls, and the positioning hole includes multiple circumferential hole walls. Each circumferential sidewall abuts against a corresponding circumferential hole wall. One of the connector and the positioning hole is disposed on the main frame, and the other is disposed on the extension frame.

[0015] The beneficial effects of this design are as follows: By setting up connectors and positioning holes, when the connectors are inserted into the positioning holes, each circumferential sidewall abuts against a corresponding circumferential hole wall, thus forming multiple abutment parts along the circumferential direction of the positioning holes. This allows for simultaneous positioning of the main frame and the extension frame in both the width and height directions, thereby further improving the positioning accuracy and efficiency between the main frame and the extension frame.

[0016] In one embodiment of the present invention, the circumferential sidewall of the connector is provided with a plurality of protrusions extending along the insertion direction, and the plurality of protrusions abut against the circumferential hole wall of the positioning hole.

[0017] The beneficial effects of this design are as follows: by providing a protrusion extending along the insertion direction on the circumferential sidewall, the contact area between the circumferential sidewall of the connector and the wall of the positioning hole can be reduced. This reduces the insertion friction between the connector and the positioning hole during the insertion process, which not only reduces the machining accuracy between the connector and the positioning hole and saves machining costs, but also reduces the probability of jamming during the insertion process, making the insertion process smoother.

[0018] In one embodiment of the present invention, the connector includes a groove, the groove wall forming a circumferential sidewall, the groove includes a first groove wall and two second groove walls, the two second groove walls are respectively connected to both sides of the first groove wall, the protrusion is disposed on the first groove wall and the second groove wall, and the end of the second groove wall facing away from the first groove wall abuts against the corresponding circumferential hole wall.

[0019] The beneficial effects of this design are: by setting the groove, not only can the weight of the connector be reduced, but the support strength of the connector can also be ensured, thereby improving the stability and accuracy of the connector's insertion and positioning with the positioning hole.

[0020] In one embodiment of this utility model, the extended frame is provided with a handhold on the side opposite to the connecting end.

[0021] The beneficial effects of this design are as follows: By providing a handhold, it is not only convenient to grip and fix the extended frame when it is connected to the main frame, but the handhold can also act as a reinforcing rib on the side wall of the extended frame, thereby increasing the support strength of the extended frame.

[0022] In one embodiment of this utility model, a snap-fit ​​structure is provided between the main frame and the extension frame, and the main frame and the extension frame are snapped together by the snap-fit ​​structure.

[0023] The beneficial effects of this design are as follows: By setting up a snap-fit ​​structure, a snap-fit ​​fixation can be formed at the connection position between the main frame and the expansion frame. This snap-fit ​​fixation position cooperates with the positioning connection position of the positioning structure, which can form a pre-installation relationship before the fasteners are installed on the main frame and the expansion frame. Through the pre-installation relationship, the main frame and the expansion frame can be pre-positioned and fixed before the fasteners are officially installed, reducing the adjustment work during the assembly process, thereby reducing the labor intensity of workers, and improving the efficiency of connection and assembly.

[0024] In one embodiment of this utility model, two sets of snap-fit ​​structures are provided, and the two sets of snap-fit ​​structures are respectively provided on both sides of the positioning structure.

[0025] The beneficial effects of this design are as follows: by setting up two sets of snap-fit ​​structures, which work in conjunction with the positioning structure, a relatively stable and reliable support point can be formed between the main frame and the expansion frame, thereby improving the stability of the pre-assembly relationship between the main frame and the expansion frame.

[0026] In one embodiment of this utility model, the snap-fit ​​structure includes a snap-fit ​​buckle and a snap-fit ​​hole, the snap-fit ​​buckle and the snap-fit ​​hole are adapted to each other, the snap-fit ​​buckle is disposed in one of the main frame and the expansion frame, and the snap-fit ​​hole is disposed in the other.

[0027] The advantages of this design are: the buckle and snap-fit ​​hole structure has many advantages, such as simple structure and good design flexibility, thus it has good adaptability and is easy to manufacture. At the same time, since the buckle can be directly molded on the main frame or extension frame of the upper plastic part, no other locking accessories such as screws and nuts are needed during assembly, thus saving costs.

[0028] In a second aspect, this utility model provides a sub-instrument assembly, including the main frame of any of the above embodiments.

[0029] In a third aspect, this utility model provides a vehicle that includes the sub-instrument panel assembly described in the above embodiments. Attached Figure Description

[0045] Please see Figures 1 to 9This utility model provides a main frame 100 for mounting a vehicle sub-instrument panel, a sub-instrument panel assembly, and a vehicle. The main frame 100 includes a main frame body 110, which has at least one connecting end configured to be detachably connected to an extension frame 120. The main frame 100 can independently adapt to a sub-instrument panel of one specification; when the connecting end is connected to the extension frame 120, the extended structure formed by the combination of the main frame 100 and the extension frame 120 can adapt to a sub-instrument panel main frame 100 of another specification. This configuration allows the main frame 100 to be reused across multiple vehicle models. By simply changing the design dimensions of the extension frame 120, it can be combined with the main frame 100 to form different sized structures to adapt to different specifications of sub-instrument panels. Therefore, it can reduce the cost of large production molds and tooling, not only improving the technical problem of high development and manufacturing costs of the main frame 100, but also increasing the flexibility of the design and manufacturing of the main frame 100.

[0046] Please see Figures 1 to 3 The main frame 100 provided by this utility model includes a main frame body 110, which has at least one connecting end configured to be detachably connected to an extension frame. The detachable connection method of the main frame 100 can be a snap-fit ​​connection, a bolted connection, etc. There can be one or more connecting ends. Specifically, in this embodiment, there are two connecting ends, located at opposite ends of the main frame body 110 along its length. For ease of description, the two connecting ends are defined as the first connecting end 111 and the second connecting end 114.

[0047] The main frame 100 can independently adapt to a sub-instrument panel of one size. When the connecting ends (i.e., the first connecting end 111 and / or the second connecting end 114) are connected to the extension frame 120, the extended structure formed by the combination of the main frame 100 and the extension frame 120 can adapt to a sub-instrument panel of another size. It should be noted that when the main frame 100 is used alone, it can only adapt to a sub-instrument panel of a fixed size. However, when the main frame 100 and the extension frame 120 are combined to form an extended structure, the extended structure can adapt to sub-instrument panels of multiple sizes. For example, when the main frame 100 is only connected to the extension frame 120 at the first connecting end 111, the resulting extended structure can adapt to a sub-instrument panel of one size. When the main frame 100 is only connected to the extension frame 120 at the second connecting end 114, the resulting extended structure can adapt to a sub-instrument panel of another size. When the main frame 100 is connected to the extension frame 120 at both the first connecting end 111 and the second connecting end 114, the resulting extension structure can also be adapted to a secondary instrument panel of other specifications.

[0048] In this embodiment, by connecting the main frame 100 to the extension frame 120 via a connecting end, the main frame 100 can independently adapt to one specification of sub-instrument panel. When the connecting end is connected to the extension frame 120, the extended structure formed by the combination of the main frame 100 and the extension frame 120 can adapt to another specification of sub-instrument panel. This design allows for changes in frame size by changing the design dimensions of the extension frame 120 or adjusting the combination method between the extension frame 120 and the main frame 100, thereby adapting to different specifications of sub-instrument panels. Since the main frame 100 itself is versatile, only the design of the extension frame 120 needs to be changed, thus reducing the investment in large molds and tooling. This not only reduces production costs but also improves production efficiency. Furthermore, this modular design makes the design and manufacturing of the frame more flexible. When developing new models or adjusting the specifications of the sub-instrument panel, there is no need for large-scale modifications to the main frame 100; only the extension frame 120 needs to be adjusted to meet the new requirements. This flexibility greatly shortens the development cycle and improves production efficiency.

[0049] Although the orientation of the extension frame 120 on the main frame 100 is not limited, considering that the differences between the sub-dashboards of different vehicle models are mainly in the length direction, in one embodiment of this utility model, the length direction of the main frame 100 (e.g., Figure 3 The main frame 100 (shown on the X-axis) has a first connecting end 111 and a second connecting end 114 at its two ends. The extension frame 120 has a third connecting end 121, which is detachably connected to the first connecting end 111. That is, there is one extension frame 120, and one main frame 100 is combined with one extension frame 120. This configuration allows the extension frame 120 to be connected to the first connecting end 111 of the main frame 100, thereby extending the main frame 100 in the length direction to accommodate more sub-instrument panels of different lengths, better meeting the configuration requirements of different vehicle models for sub-instrument panels of different lengths. In another embodiment, the extension frame 120 is also provided, with its third connecting end 121 detachably connected to the second connecting end 114. This allows the extension frame 120 to be connected to the second connecting end 114 of the main frame 100, also extending the main frame 100 in the length direction. In other embodiments, two extension frames 120 are provided. The third connection end 121 of one extension frame 120 is detachably connected to the first connection end 111, and the third connection end 121 of the other extension frame 120 is detachably connected to the second connection end 114. This allows the main frame 100 to be further lengthened in the length direction to match a sub-instrument panel with a larger length specification.

[0050] Please see Figure 1In one embodiment of this utility model, the main frame 100 is provided with a first accommodating cavity 112. The first accommodating cavity 112 can be used to provide storage space, install storage boxes, set up electronic device structures, etc. The structure, shape, and size of the first accommodating cavity 112 are not limited; it can be a cuboid cavity, a cube cavity, or an irregularly shaped cavity, etc. Optionally, in this embodiment, the first accommodating cavity 112 is an approximately cuboid cavity structure, and the length direction of the first accommodating cavity 112 is consistent with the length direction of the main frame 100. The extension frame 120 is provided with a second accommodating cavity 122, and the first accommodating cavity 112 and the second accommodating cavity 122 are independently arranged. The second accommodating cavity 122 can also be used to provide storage space, install storage boxes, set up electronic device interfaces, etc. By providing a second accommodating cavity 122 on the extension frame 120, when the extension frame 120 is connected to the main frame 100, the extension frame 120 can not only extend the length of the main frame 100, but also increase the overall accommodating space of the frame, so as to better match the configuration requirements of the sub-instrument panel on different vehicle models. Meanwhile, since the first accommodating cavity 112 and the second accommodating cavity 122 are independently provided, the integrity of the first accommodating cavity 112 can be maintained when the main frame 100 is used alone, thereby better meeting its own storage space and other usage requirements.

[0051] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment of this utility model, the first connecting end 111 is provided with a plurality of spaced-apart first connecting portions 113, each first connecting portion 113 having a first connecting surface 1131. The first connecting surfaces 1131 of the plurality of first connecting portions 113 may be on the same plane or on different planes. The third connecting end 121 is provided with a plurality of spaced-apart second connecting portions 123, each second connecting portion 123 having a second connecting surface 1231. The second connecting surfaces 1231 of the plurality of second connecting portions 123 may be on the same plane or on different planes, depending on the arrangement of the first connecting surfaces 1131. Each first connecting portion 113 corresponds to one second connecting portion 123, that is, each first connecting surface 1131 corresponds to one second connecting surface 1231. Optionally, in this embodiment, for ease of manufacturing, the plurality of first connecting surfaces 1131 are located on the same plane, and the plurality of second connecting surfaces 1231 are also located on the same plane. In another embodiment, the second connecting end 114 may be provided with a plurality of spaced-apart first connecting portions 113 to facilitate the connection of the third connecting end 121 with the second connecting end 114. In other embodiments, both the first connecting end 111 and the second connecting end 114 may be provided with a plurality of spaced-apart first connecting portions 113, thereby facilitating the connection of the third connecting end 121 with the first connecting end 111 and the second connecting end 114 respectively.

[0052] When the main frame 100 and the extension frame 120 are connected, the first connecting surface 1131 and the second connecting surface 1231 press against each other and are fixedly connected by fasteners 150, which can be screws, bolts, etc. Optionally, in this embodiment, the first connecting part 113 is machined with a screw hole 1132, and the second connecting part 123 is machined with a through hole 1232. The fastener 150 passes through the through hole 1232 and is screwed into the threaded hole to achieve a fixed connection between the main frame 100 and the extension frame 120. In other embodiments, the second connecting part 123 may also be machined with a screw hole 1132, and the first connecting part 113 may be machined with a through hole 1232. In this embodiment, by providing multiple first connecting portions 113 and multiple second connecting portions 123, multiple spaced local contact surfaces can be formed when the first connecting end 111 and the third connecting end 121 abut and press against each other, thereby improving the stability of the contact. This allows for a more stable and reliable connection between the extension frame 120 and the main frame 100 after the fastener 150 is fixedly connected, reducing the probability of loosening or displacement at the connection point. Furthermore, the connection method of fixing the first connecting portions 113 and the second connecting portions 123 with the fastener 150 is stable, reliable, simple in structure, and low in cost.

[0053] Please see Figure 1 , Figure 3 and Figure 5 In one embodiment of the present invention, the connecting surface formed between the first connecting portion 113 and the second connecting portion 123 extends at least partially to the outer side of the width direction of the first connecting end 111 and the third connecting end 121. At least a portion of the first connecting surface 1131 extends to the outer side of the width direction of the first connecting end 111, that is, at least a portion of the first connecting surface 1131 extends to the outer side of the width direction of the first accommodating cavity 112; at least a portion of the second connecting surface 1231 extends to the outer side of the width direction of the third connecting end 121, that is, at least a portion of the second connecting surface 1231 extends to the outer side of the width direction of the second accommodating cavity 122. When the first connecting surface 1131 and the second connecting surface 1231 are pressed together, the connecting surface formed is at least partially located on the outer side of the width direction of both the first connecting end 111 and the third connecting end 121. This configuration allows for the fixed connection of the first connecting portion 113 and the second connecting portion 123 to the outside of the first accommodating cavity 112 and the second accommodating cavity 122. This not only makes the connection between the main frame 100 and the extension frame 120 more stable and reliable, but also allows the connection position to avoid the first accommodating cavity 112 and the second accommodating cavity 122. Therefore, it is convenient to reserve connection holes on the first connecting end 111 and the third connecting end 121 without damaging the walls of the first accommodating cavity 112 and the second accommodating cavity 122.

[0054] To improve the accuracy of the connection position between the extended frame 120 and the main frame 100, optionally, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 7 In one embodiment of this utility model, a positioning structure 130 is provided between the main frame 100 and the extension frame 120 to position the connection position between the main frame 100 and the extension frame 120 when they are combined and connected. It should be noted that the positioning structure 130 can be used to position the extension frame 120 and the main frame 100 in the width direction (e.g.,...). Figure 3 Positioning can be formed on the Y-axis (as shown in the middle), or it can be formed in the height direction (e.g., Figure 3 Positioning can be formed on the Z-axis (as shown in the middle), or it can be formed in both the width and height directions.

[0055] The positioning structure 130 can have various structures. In one embodiment, the positioning structure 130 can be a protrusion and groove structure, with one of the protrusion and groove disposed on the main frame 100, i.e., on the first connecting end 111, and the other disposed on the extension frame 120, i.e., on the third connecting end 121. When the first connecting end 111 and the third connecting end 121 are connected, the protrusion and the groove engage with each other, thereby achieving mutual positioning between the main frame 100 and the extension frame 120. In other embodiments, the positioning structure 130 can also be multiple positioning pins and multiple positioning holes disposed at different positions. One of the positioning pins and positioning holes is disposed on the main frame 100, i.e., on the first connecting end 111, and the other is disposed on the extension frame 120, i.e., on the third connecting end 121. When the first connecting end 111 and the third connecting end 121 are connected, each positioning pin is inserted into a positioning hole, thereby forming multiple positioning points between the first connecting end 111 and the third connecting end 121 to achieve mutual positioning between the main frame 100 and the extension frame 120. In this embodiment, by setting the positioning structure 130, not only can the accuracy of the connection position between the main frame 100 and the extension frame 120 be improved, but also the alignment efficiency between the first connecting part 113 and the second connecting part 123 can be improved, which in turn can help improve the assembly connection efficiency between the main frame 100 and the extension frame 120.

[0056] Optionally, please refer to Figure 3 , Figure 5 and Figure 7In one embodiment of this utility model, the positioning structure 130 includes a connector 131 and a positioning hole 132 adapted to the connector 131. The connector 131 includes multiple circumferential sidewalls 1311. The specific shape of the connector 131 is not limited, for example, it can be any shape with multiple circumferential sidewalls 1311, such as a cuboid structure, a semi-cylindrical structure, or a polygonal structure. The positioning hole 132 includes multiple circumferential hole walls 1321, and each circumferential sidewall 1311 abuts against a corresponding circumferential hole wall 1321. The shape of the positioning hole 132 is adapted to the shape of the connector 131. Optionally, to facilitate the positioning processing of the connector 131 and the positioning hole 132, in this embodiment, the connector 131 has four interconnected circumferential sidewalls 1311, of which two opposing circumferential sidewalls 1311 are parallel to the width direction of the main frame 100, and the other two circumferential sidewalls 1311 are parallel to the height direction of the main frame 100. The connector 131 is disposed at the first connecting end 111 and extends along the length of the main frame 100, and the positioning hole 132 is disposed at the third connecting end 121. In other embodiments, the connector 131 may be disposed at the third connecting end 121 and the positioning hole 132 may be disposed at the first connecting end 111.

[0057] By setting the connector 131 and the positioning hole 132, when the connector 131 is inserted into the positioning hole 132, since each circumferential sidewall 1311 abuts against a corresponding circumferential hole wall 1321, multiple abutting parts can be formed along the circumferential direction of the positioning hole 132. This allows the main frame 100 and the extension frame 120 to be positioned simultaneously in the width and height directions, thereby further improving the positioning accuracy and efficiency between the main frame 100 and the extension frame 120.

[0058] Please see Figure 5 and Figure 7In one embodiment of this utility model, at least one circumferential sidewall 1311 of the connector 131 is provided with a protrusion 133 extending along the insertion direction, and the protrusion 133 abuts against the circumferential hole wall 1321 of the positioning hole 132. The number of protrusions 133 provided on each circumferential sidewall 1311 is not limited, and can be one, two or more. The cross-section of the protrusion 133 can be rectangular, semi-circular or trapezoidal, etc. Optionally, in this embodiment, two protrusions 133 are provided on each circumferential sidewall 1311, and the cross-sectional shape of the protrusions 133 is rectangular. By providing a protrusion 133 extending along the insertion direction on the circumferential sidewall 1311, the contact area between the circumferential sidewall 1311 of the connector 131 and the circumferential hole wall 1321 of the positioning hole 132 can be reduced. This reduces the insertion friction between the connector 131 and the positioning hole 132 during the insertion process. This not only reduces the machining accuracy between the connector 131 and the positioning hole 132 and saves machining costs, but also reduces the probability of jamming during the insertion process, making the insertion process smoother.

[0059] Please see Figure 5 and Figure 7 In one embodiment of this utility model, the connector 131 includes a groove 1312, the groove wall of which forms a circumferential sidewall 1311. The groove 1312 includes a first groove wall 13121 and two second groove walls 13122, which are respectively connected to both sides of the first groove wall 13121. A protrusion 133 is disposed on the first groove wall 13121 and the second groove wall 13122. One end of the second groove wall 13122 facing away from the first groove wall 13121 abuts against the corresponding circumferential hole wall 1321. By providing the groove 1312, not only can the weight of the connector 131 be reduced, but the support strength of the connector 131 can also be ensured, thereby improving the stability and accuracy of the insertion and positioning between the connector 131 and the positioning hole 132.

[0060] Since the expansion frame 120 needs to be pressed tightly against the main frame 100 during the connection process, the expansion frame 120 needs to be held and fixed throughout the connection process. To facilitate holding the expansion frame 120, optionally, please refer to... Figure 2 and Figure 3In one embodiment of this utility model, the extension frame 120 is provided with a handle 124 on the side opposite to the third connecting end 121. The handle 124 can be integrally injection molded with the extension frame 120 or fixedly connected by bolts. One or two handles 124 can be provided. The shape of the handle 124 is not limited; it can be a grip ring structure, a handle structure, or a handle structure, etc. Preferably, in this embodiment, two handles 124 are provided on the side of the extension part opposite to the third connecting end 121, and the two handles 124 are symmetrically arranged on both sides of the width direction of the extension frame 120. By providing the handles 124, it is not only convenient to grip and fix the extension frame 120 when it is connected to the main frame 100, but the handles 124 also act as reinforcing ribs for the side walls of the extension frame 120, thereby increasing the support strength of the extension frame 120.

[0061] With a positioning structure 130 provided between the main frame 100 and the extension frame 120, optionally, in one embodiment of this utility model, please refer to... Figure 1 A snap-fit ​​structure 140 is also provided between the main frame 100 and the expansion frame 200, allowing the main frame 100 and the expansion frame 120 to engage with each other. The snap-fit ​​structure 140 can be a combination of a buckle and a snap-fit ​​hole, with one of the buckle and the snap-fit ​​hole located at the first connecting end 111 of the main frame 100 and the other at the third connecting end 121 of the expansion frame 120. The buckle engages with the snap-fit ​​hole to achieve the snap-fit ​​connection between the main frame 100 and the expansion frame 120. Alternatively, the snap-fit ​​structure 140 can be a combination of a claw and a block, with one of the claw and the block located at the first connecting end 111 of the main frame 100 and the other at the third connecting end 121 of the expansion frame 120. The claw and the block engage to achieve the snap-fit ​​connection between the main frame 100 and the expansion frame 120. By setting the snap-fit ​​structure 140, a snap-fit ​​fixing point can be formed at the connection position between the main frame 100 and the expansion frame 120. This snap-fit ​​fixing point cooperates with the positioning connection point of the positioning structure 130, and a pre-installation relationship can be formed between the main frame 100 and the expansion frame 120 before the fastener 150 is installed. Through the pre-installation relationship, the main frame 100 and the expansion frame 120 can be pre-positioned and fixed before the fastener 150 is officially installed, reducing the adjustment work during the assembly process, thereby reducing the labor intensity of workers and improving the connection and assembly efficiency.

[0062] To further improve the stability of the pre-assembly relationship between the main frame 100 and the extension frame 120, optionally, please refer to... Figure 3 , Figure 5 and Figure 8In one embodiment of this utility model, two sets of snap-fit ​​structures 140 are provided, and the two sets of snap-fit ​​structures 140 are respectively provided on both sides of the positioning structure 130. The two sets of snap-fit ​​structures 140 can be provided on both sides of the positioning structure 130 along the width direction of the main frame 100, or they can be provided on both sides of the positioning structure 130 along the height direction of the main frame 100. The snap-fit ​​structures 140 and the positioning structure 130 can be set at the same height or at different heights. By providing two sets of snap-fit ​​structures 140, the two sets of snap-fit ​​structures 140 cooperate with the positioning structure 130, so that a relatively stable and reliable support point can be formed between the main frame 100 and the extension frame 120, thereby improving the stability of the pre-assembly relationship between the main frame 100 and the extension frame 120. Optionally, in this embodiment, the positioning structure 130 is provided near the upper end of the main frame 100 in the height direction, and the two sets of snap-fit ​​structures 140 are provided near the lower end of the main frame 100 in the height direction. The positioning structure 130 is positioned near the center of the main frame 100 in the width direction, and the two sets of snap-fit ​​structures 140 are positioned near the two sides of the main frame 100 in the width direction. This arrangement of the positioning structure 130 and the two sets of snap-fit ​​structures 140 can form a relatively stable triangular support between the main frame 100 and the expansion frame 120, thereby further improving the stability of the pre-assembly relationship between the main frame 100 and the expansion frame 120.

[0063] Optionally, please refer to Figure 3 , Figure 5 , Figure 8 and Figure 9In one embodiment of this utility model, the snap-fit ​​structure 140 includes a snap-fit ​​141 and a snap-fit ​​hole 142. The snap-fit ​​141 is adapted to the snap-fit ​​hole 142, that is, the snap-fit ​​141 can snap into the snap-fit ​​hole 142 to realize the snap-fit ​​connection between the main frame 100 and the extension frame 120. The snap-fit ​​141 is disposed on the extension frame 120, and the snap-fit ​​hole 142 is disposed on the main frame 100. Specifically, the snap-fit ​​141 is disposed on both sides of the extension frame 120 in the width direction and is disposed near the lower end of the extension frame 120. The snap-fit ​​hole 142 is disposed on both sides of the main frame 100 in the width direction and is disposed near the lower end of the main frame 100. The insertion direction of the snap-fit ​​141 and the snap-fit ​​hole 142 is consistent with the length direction of the main frame 100, that is, consistent with the insertion direction of the connector 131 and the positioning hole 132. The snap-fit ​​141 can be integrally formed on the extension frame 120, or it can be fixedly connected to the extension frame 120 by bolts. Optionally, in this embodiment, the buckle 141 and the expansion frame 120 are integrally injection molded and connected. In another embodiment, the buckle 141 can be disposed on the main frame 100, and the snap-fit ​​hole 142 can be disposed on the expansion frame 120. The snap-fit ​​connection between the main frame 100 and the expansion frame 120 can also be achieved through the snap-fit ​​of the buckle 141 and the snap-fit ​​hole 142. The structure of the buckle 141 and the snap-fit ​​hole 142 has many advantages such as simple structure and good design flexibility, so it has good adaptability and is easy to manufacture. At the same time, since the buckle 141 can be directly molded on the main frame 100 or the expansion frame 120 of the upper plastic part, no other locking accessories such as screws and nuts are required during assembly, thus saving costs.
