Description

Technical Field

[0001] The present invention relates to the field of vehicles, and in particular to a trunk lid latch device and a vehicle equipped with the trunk lid latch device. Background Art

[0002] A trunk latch device of a vehicle is generally used to lock / open the trunk lid of the vehicle. The trunk latch device usually includes a claw assembly and a pawl assembly. The hook portion of the claw assembly can lock a striker of the trunk lid, and the pawl assembly can lock the claw assembly.

[0003] In the process of opening the trunk lid, the pawl assembly is generally rotated to be in an open state without locking the claw assembly, and this state is maintained for a short time. In this case, the claw assembly can be rotated to open, thereby unlocking the striker. After the claw assembly is opened or after a predetermined time, the pawl assembly will return to the initial position.

[0004] In some cases, when there is an object / article with a certain mass on the trunk lid (for example, snow in winter), the weight of the object / article will prevent the trunk lid from bouncing upward, thereby preventing the impact member of the trunk lid from separating from the claw assembly and hindering the opening action of the claw assembly. After the pawl assembly is reset, the pawl assembly will re-lock the claw assembly (so that the claw assembly cannot rotate freely), so that the trunk lid is re-locked before it is opened, making the process of opening the trunk lid difficult.

[0005] The information disclosed in this background section is only intended to enhance understanding of the overall background of the invention and should not be taken as an acknowledgement or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0066] It should be understood that the accompanying drawings are not necessarily drawn to scale, but rather present simplified representations of various features to illustrate the basic principles of the present invention. The specific design features disclosed in the present invention (including, for example, specific dimensions, directions, locations, and shapes) will be determined in part by the specific intended application and use environment.

[0067] In the figures, like reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the drawing. DETAILED DESCRIPTION

[0068] The following will be referred to in detail various embodiments of the present invention, examples of which are presented in the accompanying drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to these exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternative forms, modifications, equivalent forms and other embodiments that can be included in the spirit of the present invention and within the scope defined by the appended claims.

[0069] Reference below Figures 1 to 18 A trunk lid latch device according to an embodiment of the present invention will be described.

[0070] like Figures 1 to 5 As shown, the trunk lid latch device of the present invention includes: a bracket 100 , a claw assembly 200 (Claw Assembly), a pawl assembly 300 (Pawl Assembly), a damper 400 , a sliding member 500 , a first elastic member 601 and a second elastic member 602 .

[0071] The bracket 100 is mounted to the vehicle body, such as Figure 2 As shown, a first side of the bracket 100 has a first sliding track 101 extending in a horizontal direction of the vehicle and a second sliding track 102 extending in a vertical direction, and the first sliding track 101 and the second sliding track 102 are connected to each other.

[0072] The jaw assembly 200 is in a first rotational direction (ie, Figure 1 The bracket 100 can be rotatably mounted to the second side of the bracket 100 under the action of a biasing force (in the direction of arrow A).

[0073] The pawl assembly 300 is in the second rotation direction (ie, Figure 1The pawl assembly 300 can be rotatably mounted to the second side of the bracket 100 under the action of a biasing force (in the direction of the arrow B in the figure), and enables the pawl assembly 300 to lock the pawl assembly 200. The pawl assembly 300 has a push rod 301 below its rotation center, wherein the rotation center of the pawl assembly 300 is located above the first sliding track 101.

[0074] The damper 400 can be vertically slidably mounted to the second sliding track 102 of the bracket 100, such as Figure 4 As shown, the damper 400 has a first locking surface 401 and a second locking surface 402. The first locking surface 401 is formed as an inclined plane, and the second locking surface 402 is formed as a vertical plane. The damper 400 is made of plastic or rubber.

[0075] The sliding member 500 can be installed in the first sliding track 101 of the bracket 100 in a horizontally slidable manner. Figure 5 As shown, the sliding member 500 has a third locking surface 501 corresponding to the first locking surface 401 and a fourth locking surface 502 corresponding to the second locking surface 402, and the sliding member 500 has a first receiving groove 503. Figure 6 As shown, the push rod 301 of the pawl assembly 300 extends toward the first side of the bracket 100, and extends into the first receiving groove 503 after passing through the bracket 100. The third locking surface 501 is formed as an inclined plane corresponding to the first locking surface 401, and the fourth locking surface 502 is formed as a vertical plane corresponding to the second locking surface 402.

[0076] like Figure 7 As shown, the first elastic member 601 provides a first elastic force to the damper 400 , and the first elastic force can cause the damper 400 to move downward.

[0077] The second elastic member 602 provides a second elastic force to the sliding member 500, and the second elastic force can make the sliding member move toward the damper 400, so that the first locking surface 401 of the damper 400 contacts and locks with the third locking surface 501 of the sliding member 500 (see Figure 7 ), or the second locking surface 402 of the damper 400 contacts and locks with the fourth locking surface 502 of the sliding member 500 (see Figure 8 ).

[0078] In the process of rotating the pawl assembly 300 to make it in the open state without locking the claw assembly 200, the first locking surface 401 of the damper 400 is in contact with the third locking surface 501 of the sliding member 500 and locked (see Figure 7 ) is switched to a state where the second locking surface 402 of the damper 400 contacts and locks the fourth locking surface 502 of the sliding member 500 (see Figure 8). Therefore, even if there is an object / article with a certain mass on the trunk lid, the pawl assembly 300 can still maintain the open state of the unlocked claw assembly 200, thereby ensuring that the claw assembly 200 can rotate freely and conveniently open the trunk lid.

[0079] In an exemplary embodiment, Figure 2 As shown, the middle part of the bracket 100 has a receiving slot 103 which is open upwards, and the impact piece 800 of the trunk lid in the closed state is inserted into the receiving slot 103, and the receiving slot 103 is located above the second sliding track 102. When the trunk lid is opened, the trunk lid drives the impact piece 800 to leave the receiving slot 103.

[0080] In an exemplary embodiment, Fig. 9 and Fig.10 As shown, the claw assembly 200 has an engagement surface 201, and the pawl assembly 300 has a stop surface 302 corresponding to the engagement surface 201. In the first rotation direction (ie, Fig. 9 and Fig.10 A) and a second rotation direction (ie, Fig. 9 and Fig.10 Under the combined action of the biasing force of the stop surface 302 and the engagement surface 201 (in the direction of the arrow B in the figure), the stop surface 302 can contact and lock the engagement surface 201, so that the claw assembly 200 cannot rotate. Specifically, the pawl assembly 300 can limit the claw assembly 200 from rotating in the first rotation direction (i.e., Fig. 9 and Fig.10 (direction of arrow A).

[0081] In an exemplary embodiment, Fig. 9 and Fig.10 As shown, the claw assembly 200 has a reset component 202, when the claw assembly 200 rotates in the first direction (ie, Fig. 9 and Fig.10 After rotating the damper 400 by a preset angle (in the direction of arrow A in FIG), the resetting component 202 can push the damper 400 to move upward, thereby resetting the damper 400.

[0082] In an exemplary embodiment, Figure 1 As shown, the trunk lid latch device further includes: a third elastic member 203 and a fourth elastic member 303 .

[0083] The third elastic member 203 provides the claw assembly 200 with an elastic force in the first rotation direction (ie, Figure 1The third elastic member 203 is a biasing force of the jaw assembly 200 (in the direction of the arrow A in FIG). Specifically, the third elastic member 203 may be a torsion spring. The claw assembly 200 is rotatably mounted to the bracket 100 via the shaft 204, the third elastic member 203 is sleeved on the shaft 204, one end of the third elastic member 203 is connected to the claw assembly 200, and the other end of the third elastic member 203 is connected to the bracket 100. The third elastic member 203 may be a torsion spring or a tension spring.

[0084] The fourth elastic member 303 provides the pawl assembly 300 with an elastic force in the second rotation direction (ie, Figure 1 The fourth elastic member 303 is a torsion spring. The pawl assembly 300 is rotatably mounted to the bracket 100 via the shaft 304. The fourth elastic member 303 is sleeved on the shaft 304. One end of the fourth elastic member 303 is connected to the pawl assembly 300, and the other end of the fourth elastic member 303 is connected to the bracket 100. The fourth elastic member 303 can be selected not only from a torsion spring but also from a tension spring.

[0085] In an exemplary embodiment, Figure 4 As shown, the damper 400 includes a first extension portion 406 extending in the vertical direction and a second extension portion 403 extending in the horizontal direction, the second extension portion 403 is connected to the bottom of the first extension portion 406, the first extension portion 406 can slide vertically along the second sliding track 102, the second extension portion 403 is located in the first sliding track 101, and the second extension portion 403 has a first locking surface 401 and a second locking surface 402. The upper surface 405 of the second extension portion 403 also has a mounting column 404 extending upward.

[0086] In an exemplary embodiment, one end of the first elastic member 601 is abutted against the damper 400 , and the other end of the first elastic member 601 is abutted against the bracket 100 .

[0087] Specifically, the first elastic member 601 may be a spring. The first elastic member 601 is sleeved on the mounting column 404. One end of the first elastic member 601 abuts against the upper surface 405 of the second extension portion 403 of the damper 400 (see Figure 4 ), the other end of the first elastic member 601 is stopped on the upper wall 104 of the sliding track 101 of the bracket 100 (see Figure 2 ).

[0088] In an exemplary embodiment, one end of the second elastic member 602 is abutted against the sliding member 500 , and the other end of the second elastic member 602 is abutted against a side wall of a cover body 702 of the housing to be described later.

[0089] Specifically, the second elastic member 602 may be a spring.

[0090] Specifically, Figure 5 As shown, the sliding member 500 has a second accommodating groove 504, a baffle 505 is arranged between the second accommodating groove 504 and the first accommodating groove 503, the second elastic member 602 is accommodated in the second accommodating groove 504, one end of the second elastic member 602 is abutted against the baffle 505 of the sliding member 500, and the other end of the second elastic member 602 is abutted against the side wall of the cover body 702 of the shell to be introduced later.

[0091] In an exemplary embodiment, Figure 1 As shown, the pawl assembly 300 includes a pawl 305 and a pawl overmolded part 306 .

[0092] The pawl 305 has the above-mentioned stop surface 302 . The pawl 305 is the main body of the pawl assembly 300 and can be made of metal.

[0093] The ratchet pawl overmolding 306 wraps the ratchet pawl 305 and has the above-mentioned push rod 301. The ratchet pawl overmolding 306 can be made of plastic material and can be easily processed into various shapes. When the ratchet pawl overmolding is injection molded, the push rod 301 is also injection molded together.

[0094] In an exemplary embodiment, Figure 1 As shown, the claw assembly 200 includes a claw 205 and a claw overmold 206 .

[0095] The clamping claw 205 has the above-mentioned joint surface 201. The clamping claw 205 is the main body of the clamping claw assembly 200 and can be made of metal.

[0096] The claw overmolding 206 wraps the claw 205 and has the above-mentioned reset component 202. The claw overmolding 206 can be made of plastic material and can be easily processed into various shapes. When the claw overmolding 206 is injection molded, the reset component 202 is also injection molded together.

[0097] In an exemplary embodiment, Figure 1 As shown, the trunk lid latch device further includes a base 701 and a cover body 702 .

[0098] The base 701 is mounted to the vehicle body, and the bracket 100 is mounted to the base 701. The cover 702 and the base 701 form a housing to surround the bracket 100 and the various above-mentioned parts mounted on the bracket 100.

[0099] In an exemplary embodiment, Figure 1 As shown, the trunk lid latch device further includes a driving assembly 900 , which can drive the pawl assembly 300 to rotate.

[0100] Specifically, Fig.11 As shown, the driving assembly 900 includes: a driving component 901 and a turbine 902 .

[0101] The driving component 901 is mounted to the base 701 , and has an output shaft, a portion of which is threaded to form a worm 903 .

[0102] The worm gear 902 is rotatably mounted to the base 701 . The worm gear 902 is meshed with the worm gear 903 . The worm gear 902 has a toggle portion 904 . The toggle portion 904 corresponds to the bottom end of the pawl assembly 300 .

[0103] The driving component 901 rotates the turbine 902 in the second rotation direction through the worm gear 903, thereby driving the toggle portion 904 to rotate in the second rotation direction. During the rotation of the toggle portion 904, the toggle portion 904 can toggle the third extension portion 307 at the bottom end of the pawl overmolded part 306 of the pawl assembly 300 to move away from the pawl assembly 200, so that the pawl assembly 300 rotates in the first rotation direction, thereby making the pawl assembly 300 no longer lock the pawl assembly 200.

[0104] An embodiment of the present invention further provides a vehicle equipped with the above-mentioned trunk lid latch device.

[0105] The operation of the trunk lid latch device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0106] When the trunk lid is closed, Fig. 9 and Fig.12 , in the first rotation direction provided by the third elastic member 203 (ie, Fig. 9 The biasing force of the fourth elastic member 303 and the second rotation direction (ie, the direction of the arrow A in FIG. 1 ) are provided. Fig. 9 Under the combined action of the biasing force of the pawl assembly 300 and the direction of the arrow B in the figure, the stop surface 302 of the pawl assembly 300 contacts and locks the engagement surface 201 of the claw assembly, thereby limiting the claw assembly 200 from rotating in the first rotation direction (i.e., Fig. 9 The impact member 800 on the trunk lid is restricted by the hook portion 208 of the claw assembly 200, so that the trunk lid cannot be opened.

[0107] At this time, see Figure 7 , the third locking surface 501 of the sliding member 500 contacts the first locking surface 401 of the damper 400. Therefore, under the combined effect of the second elastic force to the left in the figure provided by the second elastic member 602 and the first elastic force to the downward direction in the figure provided by the first elastic member 601, the third locking surface 501 of the sliding member 500 and the first locking surface 401 of the damper 400 are locked with each other. Fig.12As shown, through the cooperation between the third locking surface 501 and the first locking surface 401, the sliding member 500 can convert the second elastic force in the horizontal direction provided by the second elastic member 602 into a supporting force acting upward in the vertical direction. Therefore, the sliding member 500 supports the damper 400 upward through the second elastic force, so that the damper 400 can limit the shaking of the impact member 800 of the trunk lid.

[0108] The driving component 901 of the driving assembly 900 is started, and the output shaft of the driving component 901 rotates in one direction, and the toggle portion 904 rotates toward the third extension portion 307 through the worm 903 and the worm gear 902. After the toggle portion 904 contacts the third extension portion 307 of the pawl assembly 300, the toggle portion 904 pushes the third extension portion 307 of the pawl assembly 300 in a direction away from the claw assembly 200, so as to drive the pawl assembly 300 to rotate in the first rotation direction (i.e., unlock the pawl assembly 300). During the rotation of the pawl assembly 300 in the first rotation direction, the push rod 301 of the pawl assembly 300 pushes the sliding member 500 in a direction away from the damper 400 (see Fig.13 ).

[0109] like Fig.10 As shown, when the third extension portion 307 moves to a predetermined position, the pawl assembly 300 no longer locks the claw assembly 200. In this case, see Fig.13 and Fig.14 As shown, the sliding member 500 no longer locks the damper 400. In addition, under the action of the first elastic force of the first elastic member 601, the damper 400 moves downward, so that the second locking surface 402 of the damper 400 contacts the fourth locking surface 502 of the sliding member 500 (see Fig.14 ).

[0110] The bottom of the damper 400 contacts the lower wall 105 of the sliding track 101, so that the second locking surface 402 remains in contact with the fourth locking surface 502. Therefore, the damper 400 can prevent the sliding member 500 from moving toward the damper 400, thereby maintaining Fig.14 Due to the push rod 301 of the pawl assembly 300 and the first receiving groove 503 of the sliding member 500, the pawl assembly 300 can maintain Fig.10 , so that the pawl assembly 300 remains in a state of not restricting the rotation of the claw assembly 200. At this time, the output shaft of the driving component 901 rotates a predetermined angle in the opposite direction of the one direction (i.e., the driving component 901 is reset), so that the toggle portion 904 rotates in a direction away from the third extension portion 307 to the original position.

[0111] Since the pawl assembly 300 no longer restricts the rotation of the claw assembly 200 , the claw assembly 200 can rotate freely.

[0112] At this time, in the first rotation direction provided by the third elastic member 203 (ie, Fig.10 Under the action of the biasing force (in the direction of the arrow A in FIG. 1 ), the claw assembly 200 rotates in the first rotation direction (see FIG. Fig.10 ) a certain angle. If there is an object / article with a certain mass on the trunk lid, the trunk lid cannot bounce upward under the weight of the object / article. In this case, the striker 800 is still below the hook portion 208 of the claw assembly 200, limiting the further rotation of the claw assembly 200. Therefore, the restriction of the striker 800 by the hook portion 208 of the claw assembly 200 cannot be completely released.

[0113] The trunk lid is manually pushed upward to move the impact member 800 upward. During the upward movement, the impact member 800 pushes the hook portion 208 of the claw assembly 200 to further rotate in the first rotation direction, so that the hook portion 208 of the claw assembly 200 no longer restricts the impact member 800.

[0114] When the trunk lid is fully opened, the striker 800 is free from the restriction of the hook portion 208 of the claw assembly 200 (see Fig.15 ) and has left the receiving slot 103 of the bracket 100.

[0115] During the further rotation of the claw assembly 200 in the first rotation direction, the reset component 202 of the claw assembly 200 rotates to contact the damper 400 and pushes the damper 400 upward, so that the second locking surface 402 is no longer in contact with the fourth locking surface 502 of the sliding member 500, and the first locking surface 401 of the damper 400 moves to a height corresponding to the third locking surface 501 of the sliding member 500. Under the action of the second elastic force provided by the second elastic member 602, the sliding member 500 moves to the left side in the figure, so that the third locking surface 501 of the sliding member 500 contacts the first locking surface 401 of the damper 400. Under the combined action of the second elastic force provided by the second elastic member 602 to the left side in the figure and the first elastic force provided by the first elastic member 601 to the lower side in the figure, the third locking surface 501 of the sliding member 500 is locked again with the first locking surface 401 of the damper 400. Furthermore, under the action of the second elastic force provided by the second elastic member 602, the sliding member 500 moves toward the damper 400 again, and under the action of the biasing force in the second rotation direction provided by the fourth elastic member 303 and the second elastic force to the left in the figure provided by the second elastic member 602, the pawl assembly 300 rotates in the second rotation direction (see Fig.16 ).

[0116] When the trunk lid needs to be closed, the trunk lid is closed electrically or pressed downward manually, and the impact member 800 of the trunk lid impacts the claw assembly 200, driving the claw assembly 200 to rotate in the second rotation direction.

[0117] During this process, the engagement surface 207 of the claw assembly 200 contacts the engagement surface 308 of the pawl assembly 300 (see Fig.17 ) to push the pawl assembly 300 to the first rotation direction (ie, Fig.17 The pawl assembly 300 is rotated in the direction of the arrow A in the figure, so that the pawl assembly 300 makes room for the rotation of the claw assembly 200 (see Fig.18 At the same time, the pawl assembly 300 pushes the sliding member 500, so that the sliding member 500 moves a short distance in a direction away from the damper 400 (ie, to the right).

[0118] After the engagement surface 207 of the claw assembly 200 passes over the engagement surface 308 of the pawl assembly 300, the pawl assembly 300 rotates again in the second rotation direction (i.e., Fig.18 The pawl assembly 300 rotates in the direction of the arrow B in the figure, and drives the sliding member 500 to move a short distance toward the damper 400 (i.e., the left direction in the figure). It should be noted that, during the process of the pawl assembly 300 rotating in the first rotation direction, the sliding member 500 moves a short distance to the right side in the figure without causing the third locking surface 501 of the sliding member 500 to be out of contact with the first locking surface 401 of the damper 400.

[0119] When the trunk lid is fully closed, the striker 800 moves again to below the hook portion 208 of the claw assembly 200, and the stop surface 302 of the pawl assembly 300 contacts the engagement surface 201 of the claw assembly 200 again, and the claw assembly 200 is again restricted from rotating in the first rotation direction under the combined action of the biasing force in the first rotation direction and the biasing force in the second rotation direction, thereby locking the striker 800 again, that is, returning to the original position.
