Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a front outer panel locking mechanism and a vehicle. Background Art

[0002] Currently, the dash panels of commercial vehicles, both domestic and international, are typically mounted to the vehicle body via a locking mechanism. Specifically, a locking pin is secured to the dash panel, which is fixed to the vehicle body. The locking mechanism has a recess for accommodating the pin, and a locking hook is positioned at the recess's opening. The locking pin fits into the recess and engages with the hook to secure the pin. However, with the increasing pace of exterior design updates for commercial vehicles, the weight of the dash panel assembly is also increasing. During driving, this can easily cause the dash panel to wobble relative to the vehicle body, which in turn can cause the locking pin to wobble relative to the locking mechanism, resulting in unusual noise and a negative impact on the user experience. Summary of the Invention

[0003] According to one aspect of the present invention, the present invention provides a dash outer panel locking mechanism to solve the problem in the prior art that the locking pin easily shakes relative to the locking mechanism, thereby generating abnormal noise.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A dash panel locking mechanism, for mounting the dash panel on the vehicle body; comprising a locking mechanism disposed on a first one of the dash panel and the vehicle body, and a locking pin disposed on a second one of the dash panel and the vehicle body; the locking mechanism comprising:

[0006] a limit lock hook having a groove and being rotatable relative to the first of the front outer panel and the vehicle body to sequentially have a first position, an intermediate position, and a second position; when the limit lock hook is in the first position, the lock pin is capable of being inserted into the groove along the front-rear direction of the vehicle and is capable of pushing the limit lock hook toward the second position; when the limit lock hook is in the second position, the lock pin is capable of abutting against a groove wall of the groove along the front-rear direction of the vehicle;

[0007] The elastic member is used to provide an elastic force to move the limiting lock hook away from the middle position and toward the first position or the second position.

[0008] As a preferred solution of the front outer panel locking mechanism, the groove has a first side wall and a second side wall that are arranged opposite to each other. When the limiting lock hook rotates from the first position toward the second position, the second side wall is located in front of the first side wall, and the second side wall extends outward relative to the first side wall.

[0009] As a preferred solution of the front outer panel locking mechanism, the second side wall includes a main body section connected to the bottom wall of the groove and a guide section connected to the main body section, the first side wall is parallel to and opposite to the main body section, the main body section and the guide section are arranged at an angle, and the guide section extends relative to the main body section toward a side close to the first side wall.

[0010] As a preferred solution of the front outer panel locking mechanism, when the limiting lock hook is located at the second position, the locking pin can abut against the bottom wall of the groove along the left-right direction of the vehicle.

[0011] As a preferred solution of the front outer panel locking mechanism, two locking mechanisms are provided, and the limiting lock hooks of the two locking mechanisms are arranged at intervals along the left and right directions of the vehicle. When the two limiting lock hooks are both in the second position, the opening directions of the grooves of the two limiting lock hooks are opposite along the left and right directions of the vehicle.

[0012] As a preferred solution of the front outer panel locking mechanism, the locking mechanism also includes a connecting rod, one end of which is rotatably connected to the limit lock hook, and the other end can be rotated relative to the first one of the front outer panel and the vehicle body, and the elastic member is sleeved on the connecting rod.

[0013] As a preferred solution of the front outer panel locking mechanism, the limiting lock hook is rotatably connected to the first of the front outer panel and the vehicle body through a first rotating shaft, the limiting lock hook and the connecting rod are rotatably connected through a second rotating shaft, the first rotating shaft is located between the groove and the second rotating shaft, the elastic member is a compression spring, and when the limiting lock hook is in the middle position, the compression spring is in a compressed state.

[0014] As a preferred solution of the front outer panel locking mechanism, the connecting rod has a sliding groove at one end close to the first one of the front outer panel and the vehicle body, and the first one of the front outer panel and the vehicle body is fixedly provided with a connecting rod shaft, the connecting rod shaft is set in the sliding groove, and the connecting rod can rotate or slide relative to the connecting rod shaft.

[0015] As a preferred solution of the front outer panel locking mechanism, the locking mechanism also includes a first limit block and a second limit block. When the limit lock hook is in the first position, the limit lock hook abuts against the first limit block. When the limit lock hook is in the second position, the limit lock hook abuts against the second limit block.

[0016] According to another aspect of the present invention, a vehicle is provided, comprising the above-mentioned front outer panel locking mechanism, and also comprising a vehicle body and a front outer panel, wherein the locking mechanism is arranged on a first one of the front outer panel and the vehicle body, and the locking pin is arranged on a second one of the front outer panel and the vehicle body.

[0017] The beneficial effects of the present invention are:

[0018] The present invention provides a dash panel locking mechanism for mounting the dash panel to a vehicle body. The mechanism comprises a locking mechanism disposed at a first position between the dash panel and the vehicle body, and a locking pin disposed at a second position between the dash panel and the vehicle body. The locking mechanism comprises a limiting lock hook and an elastic member. The limiting lock hook has a groove and is rotatable relative to the vehicle body to sequentially have a first position, an intermediate position, and a second position. When the limiting lock hook is in the first position, the locking pin can be inserted into the groove along the front-to-back direction of the vehicle, thereby moving the locking pin into the groove and pushing the limiting lock hook toward the second position. When the limiting lock hook is in the second position, the locking pin can abut against the groove wall along the front-to-back direction of the vehicle, thereby preventing the locking pin from being disengaged from the groove along the front-to-back direction of the vehicle, causing the locking pin to be mounted in the limiting lock hook, thereby connecting the dash panel to the vehicle body. The elastic member is configured to provide an elastic force that forces the limiting lock hook away from the intermediate position and toward the first position or the second position. When the front outer panel is installed on the vehicle body, the limit lock hook in the front outer panel locking mechanism is in the first position, at this time the lock pin can be inserted into the groove along the front and rear direction of the vehicle. With the movement of the lock pin, the limit lock hook is driven to rotate toward the second position by the lock pin. When the limit lock hook moves from the first position to the middle position, the elastic member is compressed. After the limit lock hook passes the middle position, on the one hand, its original inertia will continue to drive the limit lock hook to move toward the second position. On the other hand, the elastic member will also apply an elastic force to the limit lock hook toward the second position, so that the limit lock hook moves quickly to the second position, thereby locking the front outer panel. The outer panel of the front panel is connected to the body of the vehicle. At this time, if the front outer panel is displaced relative to the body of the vehicle due to factors such as vehicle shaking, the limit lock hook will also be displaced. As long as the movement position of the limit lock hook does not exceed the middle position, the elastic member will provide an elastic force to move the limit lock hook away from the middle position and toward the second position, which can provide a buffer for the movement of the limit lock hook. After the position of the limit lock hook is slightly offset, the limit lock hook can still move toward the second position driven by the elastic member, so that the limit lock hook is reset, which can avoid abnormal noise caused by the shaking of the front outer panel.

[0019] The present invention also provides a vehicle, including the above-mentioned front outer panel locking mechanism, and also including a vehicle body and a front outer panel, the locking mechanism is arranged at the first one of the front outer panel and the vehicle body, and the locking pin is arranged at the second one of the front outer panel and the vehicle body, in the front outer panel locking mechanism, if the front outer panel is displaced to a certain extent relative to the vehicle body due to factors such as vehicle shaking, the limiting lock hook will also be displaced to a certain extent, and as long as the movement position of the limiting lock hook does not exceed the middle position, the elastic member will provide an elastic force to move the limiting lock hook away from the middle position and toward the second position, which can provide buffering for the movement of the limiting lock hook, and after the position of the limiting lock hook is slightly offset, the limiting lock hook can still move toward the second position under the drive of the elastic member, so that the limiting lock hook is reset, which can avoid abnormal noise caused by shaking of the front outer panel.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0029] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0030] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on those shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0032] Currently, the dash panels of commercial vehicles, both domestic and international, are typically mounted to the vehicle body via a locking mechanism. Specifically, a locking pin is secured to the dash panel, which is fixed to the vehicle body. The locking mechanism has a recess for accommodating the pin, and a locking hook is positioned at the recess's opening. The locking pin fits into the recess and engages with the hook to secure the pin. However, with the increasing pace of exterior design updates for commercial vehicles, the weight of the dash panel assembly is also increasing. During driving, this can easily cause the dash panel to wobble relative to the vehicle body, which in turn can cause the locking pin to wobble relative to the locking mechanism, resulting in unusual noise and a negative impact on the user experience.

[0033] Reference Figure 1-Figure 3The dash panel locking mechanism is used to attach the dash panel to the vehicle body; it includes a locking mechanism disposed at a first position between the dash panel and the vehicle body, and a locking pin disposed at a second position between the dash panel and the vehicle body. This embodiment exemplifies a solution in which the locking mechanism is disposed at the vehicle body and the locking pin is disposed at the dash panel. In other embodiments, the locking mechanism may be disposed at the dash panel and the locking pin may be disposed at the vehicle body.

[0034] Continue to refer to Figure 1-Figure 3 The locking mechanism includes a limit lock hook 1, which has a groove 11 and can rotate relative to the vehicle body to sequentially have a first position, an intermediate position, and a second position. When the limit lock hook 1 is in the first position, the lock pin can be inserted into the groove 11 along the front-to-back direction of the vehicle, so that the lock pin moves into the groove 11 and can push the limit lock hook 1 toward the second position. Specifically, the opening of the groove 11 faces the front-to-back direction of the vehicle, or the opening direction of the groove 11 deviates from the front-to-back direction of the vehicle, but the lock pin can still be inserted into the groove 11 along the front-to-back direction of the vehicle. When the limit lock hook 1 is in the second position, the lock pin can abut against the groove wall of the groove 11 along the front-to-back direction of the vehicle, thereby preventing the lock pin from escaping from the groove 11 along the front-to-back direction of the vehicle, so that the lock pin is installed in the limit lock hook 1, thereby connecting the front outer panel to the vehicle body.

[0035] Continue to refer to Figure 1-Figure 3 The locking mechanism also includes an elastic member 2, which is used to provide an elastic force to move the limiting lock hook 1 away from the middle position and toward the first position or the second position. Before the front outer panel is installed on the vehicle body, the limiting lock hook 1 in the front outer panel locking mechanism is in the first position. At this time, the lock pin can be inserted into the groove 11 along the front and rear direction of the vehicle. As the lock pin moves, the limiting lock hook 1 is driven to rotate toward the second position through the lock pin. When the limiting lock hook 1 moves from the first position to the middle position, the elastic member 2 is compressed. After the limiting lock hook 1 passes the middle position, on the one hand, its original inertia will continue to drive the limiting lock hook 1 to move toward the second position. On the other hand, the elastic member 2 will also apply an elastic force to the limiting lock hook 1 toward the second position, so that the limiting lock hook 1 moves quickly to the second position, thereby The front outer panel is connected to the vehicle body. At this time, if the front outer panel is displaced relative to the vehicle body due to factors such as vehicle shaking, the limit lock hook 1 will also be displaced. As long as the movement position of the limit lock hook 1 does not exceed the middle position, the elastic member 2 will provide an elastic force to move the limit lock hook 1 away from the middle position and toward the second position, which can provide a buffer for the movement of the limit lock hook 1. After the position of the limit lock hook 1 is slightly offset, the limit lock hook 1 can still move toward the second position driven by the elastic member 2, so that the limit lock hook 1 is reset, which can avoid abnormal noise caused by the shaking of the front outer panel.

[0036] Optionally, the limit lock hook 1 is made of black EPDM rubber and is formed by integral injection molding. By designing relevant molds, a one-mold multi-cavity structure can be achieved, thereby improving production efficiency and meeting the needs of production and loading.

[0037] Continue to refer to Figure 1-Figure 3 The groove 11 has a first side wall 111 and a second side wall 112 which are arranged opposite to each other. When the limit lock hook 1 rotates from the first position to the second position, the second side wall 112 is located in front of the first side wall 111, and the second side wall 112 extends outward relative to the first side wall 111. The extended part of the second side wall 112 can guide or drive the limit lock hook 1 to move. When the lock pin contacts this part of the second side wall 112, the lock pin can be guided by the second side wall 112. In addition, if the extension direction of this part of the second side wall 112 is inconsistent with the movement direction of the lock pin (that is, the front and rear direction of the vehicle), the lock pin can also be subjected to force on this part of the second side wall 112, causing the limit lock hook 1 to rotate relative to the vehicle body in advance, so that the groove 11 is opposite to the lock pin, so that the lock pin can move smoothly between the first side wall 111 and the second side wall 112.

[0038] Continue to refer to Figure 1-Figure 3 The second side wall 112 includes a body section 1121 connected to the bottom wall 113 of the groove 11, and a guide section 1122 connected to the body section 1121. The first side wall 111 and the body section 1121 are parallel and opposite to each other. The body section 1121 and the guide section 1122 are arranged at an angle, and the guide section 1122 extends toward the side closer to the first side wall 111 relative to the body section 1121. This arrangement allows the locking pin to contact the guide section 1122 as early as possible before entering between the first side wall 111 and the body section 1121, and the guide section 1122 guides the locking pin or drives the limited lock hook 1 to move. Optionally, the first side wall 111 and the body section 1121 are the same length.

[0039] In this embodiment, when the limit lock hook 1 is in the first position, the guide section 1122 is parallel to the front and rear direction of the vehicle, and the first side wall 111 and the main body section 1121 are both set at an angle to the front and rear direction of the vehicle. At this time, along the front and rear direction of the vehicle, when the lock pin moves to the position of the guide section 1122, the lock pin can contact the guide section 1122, further improving the guiding effect, and at this time the lock pin will not push the limit lock hook 1 to move. Only when the lock pin moves further between the first side wall 111 and the main body section 1121, will it push the limit lock hook 1 to move.

[0040] In other embodiments, when the limit lock hook 1 is in the first position, the guide section 1122 is set at an angle to the front-to-back direction of the vehicle. At this time, along the front-to-back direction of the vehicle, before the locking pin moves to between the first side wall 111 and the main body section 1121, it will first contact the guide section 1122. At this time, the locking pin applies a thrust to the guide section 1122 to drive the limit lock hook 1 to rotate relative to the vehicle body in advance, so that the opening formed between the first side wall 111 and the main body section 1121 is opposite to the locking pin, so that the locking pin can move smoothly between the first side wall 111 and the main body section 1121.

[0041] Optionally, in order to facilitate demoulding, both side walls of the groove 11 may be designed with a certain draft angle, for example, 3°.

[0042] Optionally, the length of the first sidewall 111 and the body section 1121 is L1, and the length of the guide section 1122 is L2, and 1.5≤L1 / L2≤3, so that the length of the guide section 1122 is moderate and meets practical needs. Specifically, the value of L1 / L2 can be 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, or 3.0, and is specifically 2.0 in this embodiment. More specifically, the length of the first sidewall 111 and the body section 1121 is 40 mm, and the length of the guide section 1122 is 20 mm.

[0043] Continue to refer to Figure 1-Figure 3 When the position-limiting lock hook 1 is in the second position, the lock pin can abut against the bottom wall 113 of the groove 11 along the left-right direction of the vehicle, thereby limiting the lock pin in the front-to-back direction of the vehicle while also limiting the lock pin in the left-to-right direction of the vehicle. Specifically, when the position-limiting lock hook 1 is in the second position, the bottom wall 113 of the groove 11 is parallel to the front-to-back direction of the vehicle, or the bottom wall 113 of the groove 11 forms an angle with the front-to-back direction of the vehicle, but the lock pin can still abut against the bottom wall 113 of the groove 11 along the left-to-right direction of the vehicle.

[0044] Continue to refer to Figure 1-Figure 3 , there are two locking mechanisms, and the limiting lock hooks 1 of the two locking mechanisms are spaced apart along the left and right directions of the vehicle. When the two limiting lock hooks 1 are both in the second position, along the left and right directions of the vehicle, the opening directions of the grooves 11 of the two limiting lock hooks 1 are opposite. Specifically, there are two optional solutions, one of which is as follows Figure 2 As shown, the opening directions of the grooves 11 of the two limit lock hooks 1 are opposite to each other, or as shown in FIG. Figure 3As shown, the opening directions of the grooves 11 of the two limiting lock hooks 1 are facing each other. Regardless of which solution is used, the two limiting lock hooks 1 can limit the lock pin along the front-to-back direction of the vehicle, and one limiting lock hook 1 can prevent the lock pin from deviating to the left side of the vehicle, while the other limiting lock hook 1 can prevent the lock pin from deviating to the right side of the vehicle.

[0045] Continue to refer to Figure 1-Figure 3 The locking mechanism also includes a connecting rod 3, one end of the connecting rod 3 is rotatably connected to the limit lock hook 1, and the other end can rotate relative to the first of the front outer panel and the vehicle body. The elastic member 2 is sleeved on the connecting rod 3, so that the elastic member 2 always extends or compresses along the extension direction of the connecting rod 3, avoiding the position of the elastic member 2 from being offset.

[0046] Continue to refer to Figure 1-Figure 3 The limiting lock hook 1 is rotationally connected to the first of the front outer panel and the vehicle body via a first rotating shaft 41. The limiting lock hook 1 and the connecting rod 3 are rotationally connected via a second rotating shaft 42. The first rotating shaft 41 is located between the groove 11 and the second rotating shaft 42. The elastic member 2 is a compression spring. When the limiting lock hook 1 is in the middle position, the compression spring is in a compressed state. Optionally, the compression spring is in a compressed state regardless of whether the limiting lock hook 1 is in the first position, the middle position, or the second position. When the limiting lock hook 1 is in the middle position, the length of the compression spring is the shortest, the compression amount is the largest, and the elastic force it can provide is also the largest.

[0047] As an alternative, the second rotating shaft 42 is located between the groove 11 and the first rotating shaft 41, and the elastic member 2 is a tension spring. When the limit lock hook 1 is in the middle position, the tension spring is in a stretched state. Optionally, regardless of whether the limit lock hook 1 is in the first position, the middle position, or the second position, the tension spring is in a stretched state. When the limit lock hook 1 is in the middle position, the compression spring is the longest, the stretch is the greatest, and the elastic force it can provide is also the greatest.

[0048] Continue to refer to Figure 1-Figure 3 The end of the linkage rod 3, located near the first of the front outer panel and the vehicle body, has a slide groove 31. A linkage rod shaft 43 is fixedly mounted on the first of the front outer panel and the vehicle body. The shaft 43 is disposed in the slide groove 31, and the linkage rod 3 can rotate or slide relative to the shaft 43. This reduces weight and allows the linkage rod 3 to slide relative to the first of the front outer panel and the vehicle body, thus accommodating certain manufacturing errors in the front outer panel locking mechanism.

[0049] Optionally, the connecting rod shaft 43 or the first shaft 41 can also be used as a fixing point of the boarding pedal for installing the boarding pedal.

[0050] Continue to refer to Figure 1-Figure 3The locking mechanism further includes a first limit block and a second limit block. When the limit lock hook 1 is in the first position, the limit lock hook 1 abuts against the first limit block. When the limit lock hook 1 is in the second position, the limit lock hook 1 abuts against the second limit block, thereby limiting the maximum rotation angle of the limit lock hook 1 to prevent excessive movement. The first limit block and the second limit block are provided on the linkage rod 3 or on the first of the front outer panel and the vehicle body.

[0051] The present embodiment also provides a vehicle, including the above-mentioned front outer panel locking mechanism, and also includes a vehicle body and a front outer panel, the locking mechanism is arranged at the first one of the front outer panel and the vehicle body, and the locking pin is arranged at the second one of the front outer panel and the vehicle body, in the front outer panel locking mechanism, if the front outer panel is displaced to a certain extent relative to the vehicle body due to factors such as vehicle shaking, the limiting lock hook 1 will also be displaced to a certain extent, and as long as the movement position of the limiting lock hook 1 does not exceed the middle position, the elastic member 2 will provide an elastic force to move the limiting lock hook 1 away from the middle position and toward the second position, which can provide a buffer for the movement of the limiting lock hook 1, and after the position of the limiting lock hook 1 is slightly offset, the limiting lock hook 1 can still move toward the second position under the drive of the elastic member 2, so that the limiting lock hook 1 is reset, which can avoid abnormal noise caused by shaking of the front outer panel.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
