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 provided with door handles, through which doors are opened and closed for the convenience of users.

[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 bracket capable of reciprocating linear motion, a gap is formed between the bracket and the handle portion for a user to extend into, the bracket is provided with a first support portion and a second support portion on both sides of the gap, the first support portion supports one end of the handle portion, and the second support portion supports the other end of the handle portion, the reciprocating linear motion direction of the bracket is consistent with the extension / retraction direction of the handle portion, the reciprocating linear motion of the bracket synchronously drives the first support portion and the second support portion to move in the same direction, and the first support portion and the second support 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 support 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 support portion, and the rotatable connection enables one end of the handle portion to rotate around the rotation axis of the rotatable connection to achieve the relative movement;

[0010] The actuator is connected to the bracket in a transmission manner, and is used to drive the bracket to reciprocate linearly, thereby driving the handle part to extend / retract relative to the concave cavity as a whole through the first support part and the second support part.

[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 bracket and its first support part and the second support part to move back and forth linearly at the same time, so that the handle part can be driven to extend / retract as a whole relative to the concave cavity, and there is no need to reset it with a torsion spring with large elastic force, nor is there a need to set up a complex double swing arm structure. In addition, one end of the handle part and the first support 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 support 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 support part and the second support 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 reciprocating linear motion of the first support part and the second support part, and the direction of the reciprocating linear motion of the first support part and the second support 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 to reducing the structural volume and reducing the production cost.

DETAILED DESCRIPTION

[0050] 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.

[0051] The present invention is further described in detail below:

[0052] like Figures 1 to 20 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.

[0053] The door handle of the present disclosure further comprises:

[0054] A bracket 36 capable of reciprocating linear motion, a gap 37 is formed between the bracket 36 and the handle portion for the user to extend into, the bracket 36 is provided with a first support portion 6 and a second support portion 7 on both sides of the gap 37, the first support portion 6 supports one end of the handle portion, and the second support portion 7 supports the other end of the handle portion, the reciprocating linear motion direction of the bracket 36 is consistent with the extension / retraction direction of the handle portion, the reciprocating linear motion of the bracket 36 synchronously drives the first support portion 6 and the second support portion 7 to move in the same direction, and the first support portion 6 and the second support portion 7 are used to drive the handle portion to extend / retract as a whole relative to the concave cavity 3;

[0055] Furthermore, one end of the handle portion and the first support 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 support 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;

[0056] The actuator 8 is in transmission connection with the bracket 36 , and is used to drive the bracket 36 to reciprocate linearly, thereby driving the handle portion to extend / retract as a whole relative to the concave cavity 3 through the first support portion 6 and the second support portion 7 .

[0057] 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.

[0058] In order to facilitate connection with vehicles, or modular design, the door handle also includes a mounting seat 27, which is connected to the door panel of the vehicle through the mounting seat 27, and the mounting seat 27 is used to install the support handle part and the bracket 36. Specifically, it also includes the mounting seat 27, and the bracket 36 is movably matched in the mounting seat 27. The upper side of the mounting seat 27 is provided with a depression as a concave cavity 3, and the depression is provided with a through hole 38 that is movably matched with the first support part 6 and the second support part 7, and the through hole 38 is used for the first support part 6 and the second support part 7 to extend / retract.

[0059] 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.

[0060] Embodiment 1:

[0061] like Figure 4 , 5 As shown in , 6, 7, 12, 14, 15, 16, and 17, the actuator 8 is drivingly connected to the bracket 36 via a screw rod and nut.

[0062] In some embodiments, the bracket 36 is provided with a spiral portion 13, and the spiral portion 13 is rotatably matched with the screw rod 12, the screw rod 12 is axially limited and rotatable, and a synchronous belt 34 is connected between the screw rod 12 and the actuator 8, and the actuator 8 rotates to drive the synchronous belt 34, and the synchronous belt 34 drives the bracket 36 to move linearly. In this way, the screw rod 12 only needs to rotate without axial movement, which significantly reduces the complexity of the structure and makes the spatial layout easier.

[0063] The spiral portion 13 may be a threaded hole directly formed in the bracket 36 , or a nut may be connected in the bracket 36 and the threaded hole is provided by the nut.

[0064] In this example, the bracket 36 is configured as a U-shaped member, and two ends of the U-shaped member are respectively a first supporting portion 6 and a second supporting portion 7 .

[0065] like Fig.12 , 13 , 14, 16, and 17, in the case of a mounting seat 27, a connecting opening is provided at the lower side of the mounting seat 27, a bottom 45 is provided in the recess, and through holes 38 are provided on both sides of the bottom 45, respectively. The two through holes 38 are used for the first support part 6 and the second support part 7 to extend / retract, respectively. The connecting opening is connected to a base 40 located at the lower side of the recess, so that the screw rod 12 is axially limited and rotatably connected between the bottom 45 and the base 40. The rotatable connection can be achieved by setting a bearing 29 between the upper end of the screw rod 12 and the bottom 45, and similarly, setting a bearing 29 between the lower end of the screw rod 12 and the base 40. In this way, on the one hand, it is convenient to manufacture, on the other hand, it is more convenient to set the axial limit and rotatable setting of the screw rod 12, and it is more reliable after setting, and on the other hand, it is conducive to the thickness of the entire door handle to be thinner.

[0066] In some embodiments, Fig.14 , 16 17, the actuator 8 is distributed transversely and is located on one side of the handle portion. The screw rod 12 is one or more, and in this example, one is arranged in the middle, and the synchronous belt 34 is also distributed transversely and is roughly parallel to the bracket 36. The lower end of the screw rod 12 is connected to a synchronous wheel 39, one end of the synchronous belt 34 is connected to the synchronous wheel 39, and the other end of the synchronous belt 34 is connected to the actuator 8, that is, the actuator 8 is also provided with a synchronous wheel 39. The synchronous wheel 39 and the synchronous belt 34 can realize a more accurate rotation of the screw rod 12, which is conducive to the accuracy of the telescopic stroke of the handle portion, and the cost of realization is low, and the durability and reliability are also good. The above technical solution is also conducive to the arrangement of the actuator 8, and it is convenient for production and assembly, and the thickness of the entire door handle is thinner.

[0067] 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 bracket 36 and its first support portion 6 and second support 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 movement of the bracket 36 and its first support portion 6 and second support portion 7. In this example, a worm gear is used as a stall self-locking structure, which 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.

[0068] 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.

[0069] In this example, when the electric motor stops, the self-locking structure keeps the synchronous belt 34 in position, and then keeps the screw rod 12 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 synchronous belt 34.

[0070] In some embodiments, Fig.14 , 15 As shown in Figures 16 and 17, the present disclosure further includes a first elastic member 14 provided on the handle portion, 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 support 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 support portion 6 so that the handle portion and the first support 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 make the handle portion and the first support portion 6 relatively separated, and 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 support part 6; on the other hand, the first support 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 support part 6 can move relative to each other, so the first elastic member 14 provides a 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 support part 6.

[0071] In some embodiments, Fig.14 , 15, 16, and 17, further comprising a connecting member 15, the connecting member 15 is connected to the top 16 of the first supporting portion 6, a supporting portion 17 is provided between the main body 2 of the handle portion and the top 16, the supporting portion 17 comprises 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 supporting 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.

[0072] Furthermore, Fig.14 , 15 As shown in FIGS. 16 and 17, 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.

[0073] In some embodiments, Figure 4 , 5 As shown in Figures 6, 12, and 14, a first guide structure is provided between the inner wall of the mounting seat 27 and the bracket 36, and the first guide structure is used to guide the movement of the support bracket 36. In this way, when the first support portion 6 and the second support portion 7 are used to drive the handle portion to extend / retract as a whole relative to the concave cavity 3, the first guide structure guides the movement of the support bracket 36, which can make the movement of the bracket 36 more stable and reliable. In addition, due to the guiding support of the first guide structure, the lateral load of the screw rod 12 can be smaller, that is, the bracket 36 is mainly guided and supported by the first guide structure, which significantly reduces the lateral support requirements of the screw rod 12 for the bracket 36. The screw rod 12 mainly plays an axial driving role. Therefore, on the one hand, the structure is further simplified, and on the other hand, the bracket 36 is not easy to shake, avoiding problems with the spiral fit with the screw rod 12. In this example, the screw rod 12 is centrally arranged, and the spiral portion 13 is also centrally arranged. A guide matching portion 35 is respectively arranged on both sides of the spiral portion 13. Accordingly, a third guide groove 44 is arranged on the inner side wall of the mounting seat 27. The third guide grooves 44 located on both sides of the bracket 36 guide and support the guide matching portion 35, and further guide and support the spiral portion 13. In this example, the guide matching portion 35 is a square block, and the shape of the third guide groove 44 is a square groove, see Figure 4 , 5 , 12, and 14.

[0074] In order to better guide the support, in some embodiments, such as Figure 7 , 13 As shown, a second guide structure is provided between the inner side wall of the mounting seat 27 and the handle portion, and the second guide structure is used to guide and support the movement of the handle portion. In this example, the handle portion includes a cover shell 1 and a body 2. The body 2 is a main structural member. Guide portions 30 are provided on both sides of the first support portion 6 and the second support portion 7 of the body 2, with a total of four guide portions 30. Correspondingly, the mounting seat 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 portion. In this way, when the first support part 6 and the second support 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 by the guide part 30 and the second guide groove 32 can make the movement of the handle part more stable and reliable. In addition, since the guide part 30 and the second guide groove 32 are guided and supported, the main body 2 is guided and supported by the second guide groove 32, that is, the handle part is mainly guided and supported by the second guide groove 32, which significantly reduces the support requirements of the first support part 6 and the second support part 7 for the main body 2. The first support part 6 and the second support part 7 mainly play a driving role. Therefore, on the one hand, the structure is further simplified, and on the other hand, the first support part 6 and the second support part 7 are not easy to shake, thereby avoiding movement jamming and problems with the screw nut spiral matching.

[0075] In some embodiments, Fig.14 , 16 17, it also includes a second elastic member 21 provided at the rotatable connection between the handle portion and the second support 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 support portion 7, or set the second elastic member 21 to a preset elastic force state, which fixes the handle portion and the first support portion 6 relatively 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 support portion 6 and the second support portion 7 to be stable and not loose. In addition, after the user pulls the handle portion, the handle portion can be reliably reset.

[0076] In some embodiments, Figure 4 , 5As shown in , 6 and 7, 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 rotatably connected to the body 2 of the handle portion, the other end of the transmission connecting rod 22 is provided with a lever 23, the zipper connecting portion 4 is provided with an idle stroke groove 24, the lever 23 and the idle stroke groove 24 are movably matched, when the first supporting portion 6 and the second supporting portion 7 drive the handle portion to extend as a whole relative to the concave cavity 3, the body 2 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, and the stop The end 25 is for example against a mating surface, a mating depression, a mating protrusion, etc. When the handle part is in the extended state, the user applies force to make one end of the body 2 rotate around the rotating shaft 11 to achieve the relative movement, the body 2 drives the lever 23 to move further through the transmission connecting rod 22, and the lever 23 and the stop end 25 are against and 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 is rotated and reset. 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.

[0077] In order to ensure stable and reliable movement, Fig.16 , 17 As shown, a first guide groove 31 is also provided on the mounting seat 27, and the lever 23 passes through the first guide groove 31 and then cooperates in the idle travel groove 24. The lever 23 cooperates with the first guide groove 31 for guiding and supporting. Therefore, when the transmission connecting rod 22 drives the lever 23 to move, the reciprocating motion trajectory of the lever 23 is accurate, and the motion is stable and reliable.

[0078] In some embodiments, in order to further simplify the structure and facilitate assembly, Fig.13 As shown, a rotation fitting hole is provided at the upper end of the second support portion 7, and the rotating shaft 11 is inserted from the side wall of one side of the main body 2 and passes through the rotation fitting hole and then inserted into the side wall of the other side of the main body 2 to form a rotation connection, while also supporting the main body 2 and realizing the connection between the second support portion 7 and the other end of the handle portion.

[0079] From the above, it can be seen that, driven by the actuator 8, the bracket 36 and its first support part 6 and the second support part 7 drive the handle part 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.

[0080] 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.

[0081] Embodiment 2:

[0082] Compared with the first embodiment, the main differences are as follows: other identical or similar structures can directly adopt the structure of the first embodiment.

[0083] The actuator 8 and the bracket 36 are connected by a gear rack transmission.

[0084] Since the rack 9 and the gear 10 have low purchase costs, high strength, and stable and reliable transmission, they are beneficial to reducing the cost of the door handle disclosed, improving ice-breaking performance, and improving reliability.

[0085] In this example, if Figure 8 , 9 As shown in Figures 10, 18, 19 and 20, the bracket 36 is connected to the rack 9, and the rack 9 is arranged perpendicular to the bracket 36. The rack 9 rotates with the gear 10, and a transmission shaft 28 is connected between the gear 10 and the actuator 8. The actuator 8 rotates to drive the transmission shaft 28, and the transmission shaft 28 drives the gear 10 to rotate. The rotation of the gear 10 drives the rack 9 to move linearly, and the linear movement of the rack 9 drives the bracket 36 to move linearly.

[0086] In the case of a mounting seat 27, a connecting opening is provided at the lower side of the mounting seat 27, a bottom 45 is provided in the recess, through holes 38 are provided on both sides of the bottom 45, and the two through holes 38 are used for the first support part 6 and the second support part 7 to extend / retract, respectively. The connecting opening is connected to a base 40 located at the lower side of the recess, the bottom 45 is provided with a first pillar 41 extending downward, and the base 40 is provided with a second pillar 42 extending upward. After the base 40 is connected to the mounting seat 27, the lower end of the first pillar 41 and the upper end of the second pillar 42 form a bearing seat 33 so that the bearing 29 is restricted between the first pillar 41 and the second pillar 42. The transmission shaft 28 is connected to the bearing 29, which can be seen in Fig.19 This makes production easier.

[0087] like Figure 8 , 9 As shown in FIG. 10 , a receiving portion 46 is further provided on the lower side of the bottom 45 to accommodate the rack 9 that exceeds the bottom 45 , so that the bottom 45 can be made thinner. Fig.18 , 19 In FIG. 20 , the accommodating portion 46 is not visible because the AA cross-section avoids the accommodating portion 46 .

[0088] In this example, two bearing seats 33 and two bearings 29 are provided along the axial direction, and the two bearing seats 33 are respectively located on two lateral sides of the rack 9 .

[0089] like Figure 8 , 9 As shown in FIGS. 18 and 19 , the bracket 36 is provided with a guide hole 43, and the first pillar 41 is guided and matched with the guide hole 43, and the first pillar 41 also plays a guiding role in the linear motion of the bracket 36. In this way, the first pillar 41 is convenient, which is conducive to a compact structure. In addition, the first pillar 41 can also be used for guiding, improving the motion stability of the bracket 36 at the rack 9, which is conducive to the transmission stability of the rack 9 and the gear 10.

[0090] The transmission connection between the actuator 8 and the bracket 36 can also adopt other structures, such as an electromagnetic telescopic part, and the actuator 8 correspondingly adopts an electromagnetic coil, and uses the electromagnetic driving principle of the electromagnetic coil to drive the bracket 36 to move. Of course, other structures are also possible, and it is impossible to cite them one by one. All transmission connection structural solutions between the actuator 8 and the bracket 36 applicable to the present disclosure can be applied to the present disclosure.

[0091] When understanding the present invention, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0092] The above description is only an illustrative embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
