Description

Technical Field

[0001] The invention relates to the technical field of door opening devices, in particular to a door handle. Background Art

[0002] Vehicles are generally equipped with door handles. Some door handles have a handle portion fixed relative to the vehicle body so that the user can operate the handle portion to open the door, while some door handles have a handle portion that needs to be extended relative to the vehicle body before the user can operate the handle portion to open the door. For example, most new energy vehicles currently on the market use retractable door handles. Such door handles generally include a handle portion and a concave cavity for accommodating the handle portion. The handle portion cooperates with the concave cavity. When the door needs to be opened (for example, unlocking the vehicle to get on board), the handle portion can be extended from the concave cavity, so that the user can pull the handle portion to open the door. When the user gets on board and needs to drive, the handle portion retracts into the concave cavity. In this way, it not only has a sense of technology, but also the handle portion will not be abrupt relative to the surface of the vehicle body, which is also conducive to reducing wind resistance.

[0003] In order to realize the overall entry and exit of the handle part in the concave cavity, there is a commonly used solution at present. Specifically, the solution includes an actuator, a double swing arm and a torsion spring. One end of the double swing arm is rotatably connected to one side of the vehicle body, and the other end of the double swing arm is connected to the handle part. Each swing arm in the double swing arm is sleeved with a torsion spring. The actuator includes a telescopic push rod, which is arranged transversely relative to the movement direction of the handle part. When the push rod is extended transversely, the swing arm of the double swing arm close to the push rod side is pushed to swing, and the other swing arm follows the swing, so that the other end of the double swing arm extends the handle part out of the concave cavity. This process is the extension process. When it is needed When retracting, the push rod is loosened, and the double swing arm reverses and resets under the action of the torsion spring. Then the other end of the double swing arm retracts the handle part into the concave cavity, and also pushes the push rod back to its original position. This process is the retraction process. In the aforementioned extension process, it is necessary to overcome the elastic force of the torsion spring. If ice is formed, it is also necessary to overcome the resistance of the ice layer. In the aforementioned retraction process, since it is necessary to retract reliably and reliably fix the handle part relative to the concave cavity after retraction, a torsion spring with very large elastic force is required, resulting in the force of the push rod during the extension process being mainly used to overcome the elastic force of the torsion spring. The force used to break the ice is insufficient, and it is difficult to break the ice, or it is impossible to break the ice.

[0004] As mentioned above, since the handle part needs to enter and exit the cavity as a whole, once it freezes in cold weather, the handle part cannot be extended out of the cavity. Therefore, a variety of ice-breaking solutions have been proposed. Some solutions use heating to melt ice, which requires the addition of a heating structure, resulting in a complex structure, high energy consumption, and low reliability. Some use a push rod to loosen the ice layer, which requires the addition of another set of push rods, resulting in a complex structure and a larger volume. There are also complex force systems that are constructed to break the ice layer through a composite force. It is impossible to list all the various solutions. It can be seen that there are currently many solutions for breaking ice, and there is no clear rule to follow, which makes it difficult to improve.

[0005] The present disclosure specifically proposes a door handle solution, which is conducive to breaking ice and has a simple structure and good reliability. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a door handle which is conducive to breaking ice and has a simple structure and good reliability.

[0007] Compared with the prior art, the present invention provides a door handle, comprising a handle portion, a cavity for accommodating the handle portion, and a zipper connection portion, wherein the handle portion cooperates with the cavity, the handle portion can be extended / retracted as a whole relative to the cavity, the handle portion is connected to the zipper connection portion, and a user pulls the handle portion to indirectly pull the zipper connection portion, and further comprising:

[0008] A first linear telescopic portion and a second linear telescopic portion, the first linear telescopic portion and the second linear telescopic portion are arranged in parallel, the first linear telescopic portion supports one end of the handle portion, the second linear telescopic portion supports the other end of the handle portion, the telescopic directions of the first linear telescopic portion and the second linear telescopic portion are consistent with the extension / retraction direction of the handle portion, and the first linear telescopic portion and the second linear telescopic portion are used to drive the handle portion to extend / retract relative to the concave cavity as a whole;

[0009] Furthermore, one end of the handle portion and the first linear telescopic portion can move relative to each other so that the handle portion pulls the zipper connection portion, and the other end of the handle portion is rotatably connected to the second linear telescopic portion, and the rotatable connection enables one end of the handle portion to rotate around the rotating shaft of the rotatable connection to achieve the relative movement;

[0010] The actuator is transmission-connected with the first linear telescopic portion and the second linear telescopic portion, and is used for driving the first linear telescopic portion and the second linear telescopic portion to telescope simultaneously.

[0011] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0012] The scheme disclosed in the present invention realizes the structural scheme that the handle part can be extended / retracted as a whole relative to the concave cavity, and the structural function of how the user pulls the handle part to unlock it based on the aforementioned structural scheme. The conception is very clever; the actuator drives the first linear telescopic part and the second linear telescopic part to extend and retract at the same time, and there is no need to reset the torsion spring with large elastic force, nor is there a need to set a complex double swing arm structure. In addition, one end of the handle part and the first linear telescopic part can move relative to each other so that the handle part pulls the zipper connection part, and the other end of the handle part is rotatably connected to the second linear telescopic part. The rotatable connection enables one end of the handle part to rotate around the rotating shaft of the rotatable connection to realize the relative movement. In this way, the first linear telescopic part and the second linear telescopic part are used as the structural basis for the user to pull the handle part to move, and the structure is further simplified. In summary, the scheme disclosed in the present invention has a simple structure.

[0013] In particular, in the scheme of the present invention, the force generated by the actuator is all used for the extension and retraction of the first linear telescopic part and the second linear telescopic part, and the extension and retraction direction of the first linear telescopic part and the second linear telescopic part is consistent with the extension / retraction direction of the handle part. Then, for the extended state, the force is also the force for breaking ice. Moreover, since the force does not need to be used elsewhere, in theory, it can be almost 100% used as the force for breaking ice. Then, compared with the current technology, the electric motor of the smaller actuator can meet the use requirements of the present invention, which is of great benefit for reducing the structural volume and reducing the production cost.

[0014] Since the structure is greatly simplified and the telescopic movement method is completely different from the current solution, the telescopic movement method disclosed in the present invention is simplified, that is, a first linear telescopic part and a second linear telescopic part are adopted, and the telescopic directions of the first linear telescopic part and the second linear telescopic part are consistent with the extension / retraction direction of the handle part, so the reliability is relatively improved, that is, the reliability is good.

[0015] As an improvement, the first linear telescopic part and the second linear telescopic part both use racks, namely the first rack and the second rack, and the actuator is connected to the first linear telescopic part and the second linear telescopic part through gear transmission.

[0016] As an improvement, it also includes a transmission shaft with a transverse axis, which is connected to the actuator after passing through the first rack and the second rack in sequence, a first gear is set between the transmission shaft and the first rack, and a second gear is set between the transmission shaft and the second rack, and the transmission shaft drives the first gear and the second gear to rotate at the same time.

[0017] As an improvement, the first linear telescopic part and the second linear telescopic part adopt a screw or nut of a screw-nut structure, and the actuator is transmission-connected with the screw-nut structure to drive the first linear telescopic part and the second linear telescopic part to telescope simultaneously.

[0018] As an improvement, the actuator also includes an electric motor and a stall-self-locking structure, the electric motor is connected to the stall-self-locking structure, when the electric motor stops, the stall-self-locking structure keeps the first linear telescopic part and the second linear telescopic part in position, so that the handle part remains in an extended / retracted state, when the electric motor rotates, the electric motor drives the stall-self-locking structure to rotate to restore the telescopic movement of the first linear telescopic part and the second linear telescopic part.

[0019] As an improvement, it also includes a first elastic member arranged on the handle part, which is extended / retracted as a whole together with the handle part, one end of the first elastic member is connected to the first linear telescopic portion, and the other end of the first elastic member is connected to the handle part, and the first elastic member is used to pull the handle part toward the first linear telescopic portion so that the handle part and the first linear telescopic portion are relatively fixed together. When the user applies force to rotate one end of the handle part around the rotating shaft to achieve the relative movement, the force of the first elastic member is overcome at the same time to relatively separate the handle part and the first linear telescopic portion. When the user releases, the first elastic member pulls the handle part back to its original position.

[0020] As an improvement, it also includes a connecting piece, which is connected to the top of the first linear telescopic part, and a supporting part is provided between the handle part and the top, and the supporting part includes a first abutting surface and a second abutting surface arranged back to back, the first abutting surface abuts against the top, and the supporting part is provided with a matching hole for relative lateral movement of the connecting piece, and the connecting piece is located in the handle part after passing through the matching hole, and a first elastic piece with a preset elastic force is provided between the second abutting surface and the connecting piece. When the user applies force to make one end of the handle part rotate around the rotating shaft to realize the relative movement, the matching hole swings relative to the connecting piece together with the handle part, and the second abutting surface further compresses the first elastic piece, and the first abutting surface and the top are separated from each other to release the abutment.

[0021] As an improvement, the connecting member is a screw, the first elastic member is a compression spring, the compression spring is sleeved in the screw, and the screw pre-compresses the compression spring between the second abutting surface and the screw.

[0022] As an improvement, the invention further includes a second elastic member arranged at the rotatable connection between the handle portion and the second linear telescopic portion. The second elastic member is extended / retracted as a whole together with the handle portion. The second elastic member is used to reset the rotatable connection between the handle portion and the second linear telescopic portion, or to set the second elastic member to a preset elastic force state, which fixes the handle portion and the first linear telescopic portion relatively together.

DETAILED DESCRIPTION

[0045] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0046] The present invention is further described in detail below:

[0047] like Figures 1 to 19 As shown, the present disclosure provides a door handle, including a handle part, a cavity 3 for accommodating the handle part, and a zipper connection part 4. The handle part cooperates with the cavity 3, and the handle part can be extended / retracted as a whole relative to the cavity 3. The handle part is connected to the zipper connection part 4. The user pulls the handle part to indirectly pull the zipper connection part 4. The zipper connection part 4 is used to drive a lock rope 5, which is the zipper. The zipper connection part 4 is a rotating part, and the user pulls the handle part to indirectly pull the zipper connection part 4 to rotate.

[0048] The door handle of the present disclosure further comprises:

[0049] The first linear telescopic portion 6 and the second linear telescopic portion 7 are arranged in parallel, the first linear telescopic portion 6 supports one end of the handle portion, and the second linear telescopic portion 7 supports the other end of the handle portion. The telescopic direction of the first linear telescopic portion 6 and the second linear telescopic portion 7 is consistent with the extension / retraction direction of the handle portion. The first linear telescopic portion 6 and the second linear telescopic portion 7 are used to drive the handle portion to extend / retract as a whole relative to the concave cavity 3;

[0050] Furthermore, one end of the handle portion and the first linear telescopic portion 6 can move relative to each other so that the handle portion pulls the zipper connection portion 4, and the other end of the handle portion is rotatably connected to the second linear telescopic portion 7, and the rotatable connection enables one end of the handle portion to rotate around the rotating shaft 11 of the rotatable connection to achieve the relative movement;

[0051] The actuator 8 is transmission-connected with the first linear telescopic portion 6 and the second linear telescopic portion 7 , and is used for driving the first linear telescopic portion 6 and the second linear telescopic portion 7 to telescope simultaneously.

[0052] The handle portion comprises a cover shell 1 and a body 2. After the cover shell 1 and the body 2 are connected, the handle portion has a better appearance and a better grip.

[0053] The door handle further comprises a support 27, which is connected to the door panel of the vehicle via the support 27, and the support 27 is used to support the handle portion.

[0054] The door handle disclosed in the present invention is not only used in vehicles, but also can be used in transportation tools such as airplanes and high-speed trains.

[0055] Embodiment 1:

[0056] like Figures 1 to 17 As shown, the first linear telescopic portion 6 and the second linear telescopic portion 7 both use racks, namely the first rack and the second rack, and the actuator 8 is connected to the first linear telescopic portion 6 and the second linear telescopic portion 7 through gear transmission.

[0057] Since the rack and gear have low procurement cost, high strength, and stable and reliable transmission, they are beneficial to reducing the cost of the disclosed door handle, improving ice-breaking performance, and improving reliability.

[0058] In some embodiments, Fig.10 , 12 As shown in Figures 14 and 15, the actuator 8 is distributed transversely and located on one side of the handle part, and also includes a transmission shaft 28 with a transverse axial direction. The transmission shaft 28 is connected to the actuator 8 after passing through the first rack and the second rack in sequence. A first gear 9 is arranged between the transmission shaft 28 and the first rack, and a second gear 10 is arranged between the transmission shaft 28 and the second rack. The transmission shaft 28 drives the first gear 9 and the second gear 10 to rotate at the same time. In this way, it is convenient to arrange the actuator 8, and it is also convenient to carry out production and assembly, and it also makes the thickness of the entire door handle thinner.

[0059] In some embodiments, the actuator 8 further includes an electric motor and a stall self-locking structure, the electric motor is connected to the stall self-locking structure, when the electric motor stops, the stall self-locking structure keeps the first linear telescopic portion 6 and the second linear telescopic portion 7 in place, so that the handle portion remains in an extended / retracted state, when the electric motor rotates, the electric motor drives the stall self-locking structure to rotate to restore the telescopic movement of the first linear telescopic portion 6 and the second linear telescopic portion 7. In this example, a worm gear is used as a stall self-locking structure, and the worm gear can both reduce speed and achieve reliable stall self-locking. Of course, all other stall self-locking structures applicable to the present disclosure are applicable to the present disclosure.

[0060] Compared with the prior art, the use of a stop-rotation self-locking structure can keep the handle part in a retracted state, and the handle part is not easy to fall out during a collision. The prior art requires the configuration of an anti-falling counterweight block, which not only increases the complexity of the structure, but also increases the cost and weight. Therefore, the above-mentioned improvement has important progressive significance.

[0061] In this example, when the electric motor stops, the self-locking structure keeps the transmission shaft 28 in position, and further keeps the first gear 9 and the second gear 10 in position, so that the self-locking structure keeps the handle part in the extended / retracted state. When the electric motor rotates, the electric motor drives the self-locking structure to rotate to restore the rotation of the transmission shaft 28.

[0062] In some embodiments, Fig.10 , 12 As shown in Figure 14, the present disclosure also includes a first elastic member 14 arranged on the handle portion, and the first elastic member 14 is extended / retracted as a whole together with the handle portion. One end of the first elastic member 14 is connected to the first linear telescopic portion 6, and the other end of the first elastic member 14 is connected to the handle portion. The first elastic member 14 is used to pull the handle portion toward the first linear telescopic portion 6 so that the handle portion and the first linear telescopic portion 6 are relatively fixed together. When the user applies force to rotate one end of the handle portion around the rotating shaft 11 to achieve the relative movement, the force of the first elastic member 14 is overcome at the same time to relatively separate the handle portion and the first linear telescopic portion 6. When the user releases, the first elastic member 14 pulls the handle portion back to its original position. In this way, on the one hand, there will be no looseness between the handle part and the first linear telescopic part 6; on the other hand, the first linear telescopic part 6 can reliably support the handle part when the whole part is extended / retracted, thereby improving reliability; on still another hand, the handle part and the first linear telescopic part 6 can move relative to each other, so the first elastic member 14 provides connecting force, which not only realizes the connection but also meets the need for relative movement, thereby helping to simplify the relatively movable connection between the handle part and the first linear telescopic part 6.

[0063] In some embodiments, Fig.10 , 12 14, it also includes a connecting member 15, the connecting member 15 is connected to the top 16 of the first linear telescopic portion 6, a support portion 17 is provided between the main body 2 of the handle portion and the top 16, the support portion 17 includes a first abutting surface 18 and a second abutting surface 19 arranged back to back, the first abutting surface 18 abuts against the top 16, the support portion 17 is provided with a matching hole 20 for relative lateral movement of the connecting member 15, the connecting member 15 is located in the handle portion after passing through the matching hole 20, a first elastic member 14 with a preset elastic force is provided between the second abutting surface 19 and the connecting member 15, when the user applies force to rotate one end of the handle portion around the rotating shaft 11 to achieve the relative movement, the matching hole 20 swings relative to the connecting member 15 together with the handle portion, the second abutting surface 19 further compresses the first elastic member 14, and the first abutting surface 18 and the top 16 are separated from each other to release the abutment. In this way, the above-mentioned design is very clever, making the structure simple and compact.

[0064] Furthermore, Fig.10 , 12 As shown in FIG. 14, the first elastic member 14 is a compression spring, which is sleeved in a screw, and the screw pre-compresses the compression spring between the second abutting surface 19 and the screw. In this way, on the one hand, the cost is greatly reduced, and on the other hand, the connection of the screw is conducive to fine-tuning the pre-compression degree of the compression spring, which is convenient for production and manufacturing.

[0065] In some embodiments, Figure 3 , 6 As shown in Figures 1 and 17, the body 2 is provided with guide parts 30 on both sides of the first rack and the second rack, with a total of four guide parts 30. Correspondingly, the support 27 is provided with four second guide grooves 32, and the guiding direction of the second guide grooves 32 is consistent with the extension / retraction direction of the handle part. In this way, when the first linear telescopic part 6 and the second linear telescopic part 7 are used to drive the handle part to extend / retract as a whole relative to the concave cavity 3, the guide and support of the guide parts 30 and the second guide grooves 32 can make the movement of the handle part more stable and reliable. In addition, since the guide parts 30 and the second guide grooves 32 are guided and supported, the body 2 is guided and supported by the second guide grooves 32, that is, the handle part is mainly guided and supported by the second guide grooves 32, which significantly reduces the support requirements of the first rack and the second rack on the body 2. The first rack and the second rack mainly play the role of extension / retraction. Therefore, on the one hand, the structure is further simplified, and on the other hand, the first rack and the second rack are not easy to shake, avoiding problems in meshing with the first gear 9 and the second gear 10.

[0066] In order to further stabilize the first rack and the second rack, the first rack and the second rack are both provided with a matching block 35, and the matching block 35 can be slidably matched with the corresponding side surface of the body 2 to limit the first rack and the second rack on both sides.

[0067] In some embodiments, Fig.10 , 12 14, it also includes a second elastic member 21 provided at the rotatable connection between the handle portion and the second linear telescopic portion 7, the second elastic member 21 is extended / retracted as a whole with the handle portion, and the second elastic member 21 is used to reset the rotatable connection between the handle portion and the second linear telescopic portion 7, or set the second elastic member 21 to a preset elastic force state, which relatively fixes the handle portion and the first linear telescopic portion 6 together. The second elastic member 21 is, for example, a torsion spring. In this way, during the extension / retraction process and after the extension / retraction, it is beneficial for the handle portion and the first linear telescopic portion 6 and the second linear telescopic portion 7 to be stable and not loose. In addition, after the user pulls the handle portion, the handle portion can be reliably reset.

[0068] In some embodiments, Figure 3 , 6As shown in FIGS. 8, 10, 12 and 14, a transmission connecting rod 22 is provided between the handle portion and the zipper connecting portion 4, one end of the transmission connecting rod 22 is connected to the handle portion, and the other end of the transmission connecting rod 22 is provided with a lever 23, and the zipper connecting portion 4 is provided with an idle stroke groove 24, and the lever 23 and the idle stroke groove 24 are movably matched, and when the first linear telescopic portion 6 and the second linear telescopic portion 7 drive the handle portion to extend as a whole relative to the concave cavity 3, the handle portion simultaneously drives the lever 23 through the transmission connecting rod 22 to move in the idle stroke groove 24 to the stop end 25 or close to the stop end 25. , the stop end 25 is for example against a matching surface, a matching recess, a matching protrusion, etc. When the handle part is in the extended state, when the user applies force to make one end of the handle part rotate around the rotating shaft 11 to achieve the relative movement, the handle part drives the lever 23 to move further through the transmission connecting rod 22, and the lever 23 and the stop end 25 are against each other to drive the zipper connection part 4 to move to achieve the purpose of driving the zipper; the zipper connection part 4 is connected to the third elastic member 26, and the third elastic member 26 resets the zipper connection part 4 when the handle part rotates and resets. After such a design, on the one hand, the zipper connection part 4 will not rotate during the extension process, and the zipper connection part 4 will not consume the power of the actuator 8, which is conducive to breaking ice. On the other hand, the structure is simple and reliable. When it is extended to the right position, the lever 23 is driven to move further by the user's force, so that the door is unlocked and opened in one go, and the user experience is good. The third elastic member 26 is for example a torsion spring.

[0069] In order to ensure stable and reliable movement, two transmission connecting rods 22 are arranged in parallel. In addition, a first guide groove 31 is provided on the support 27. The shift rod 23 passes through the first guide groove 31 and then cooperates in the idle stroke groove 24. The shift rod 23 cooperates with the first guide groove 31 for guiding and supporting. Therefore, when the transmission connecting rod 22 drives the shift rod 23 to move, the reciprocating motion trajectory of the shift rod 23 is accurate and the movement is stable and reliable.

[0070] In some embodiments, in order to further simplify the structure and facilitate assembly, Fig.16 As shown, a rotation fitting hole is provided at the upper end of the second linear telescopic portion 7, and the rotating shaft 11 is inserted from the side wall of one side of the main body and passes through the rotation fitting hole and then inserted into the side wall of the other side of the main body to form a rotation connection, while also supporting the main body and realizing the connection between the second linear telescopic portion 7 and the other end of the handle portion.

[0071] From the above, it can be seen that, driven by the actuator 8, the first linear telescopic portion 6 and the second linear telescopic portion 7 drive the handle portion to extend / retract as a whole relative to the concave cavity 3. Although the first elastic member 14, the second elastic member 21, and the third elastic member 26 are also provided, when the whole is extended / retracted, there is no need to overcome the power of the first elastic member 14, the second elastic member 21, and the third elastic member 26, and the first elastic member 14, the second elastic member 21, and the third elastic member 26 do not serve as a reset force for the overall retraction. Therefore, the power of the actuator 8 can be almost 100% used for breaking ice. Without increasing the size of the actuator 8, ice breaking can be reliably achieved, and the ice breaking ability is strong.

[0072] Since no elastic member is needed to provide a restoring force for the entire structure to be retracted and maintained in the retracted state, the elastic force required of the first elastic member 14 , the second elastic member 21 , and the third elastic member 26 is much smaller.
