DETAILED DESCRIPTION

[0049] The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application, and cannot be explained as the limitation of the present application.

[0050] Embodiments of the present application: as Figure 1As shown in Fig. 7, the present application discloses a lace tension assembly, which comprises a lace tension module 100 and a connecting member 200 for connecting the lace tension module 100 and a wearable article. The connecting member 200 is formed with a mating surface 201 for mating with the wearable article, and an outer wall surface 202 opposite to the mating surface 201. The lace tension module 100 has an operating portion 101 exposed outside the outer wall surface 202.

[0051] The lace tension module 100 is used for controlling the lace tension or slack of the flexible substrate on the wearable article, so as to tighten or slack the flexible substrate. The wearable article is generally equipped with a flexible substrate, and the lace is arranged on the flexible substrate. The lace tension module 100 is generally made of hard plastic, and it is not conducive to the installation and fixation of the lace tension module 100 to be directly installed and fixed on the flexible substrate. In the present embodiment, the lace tension module 100 is connected to the connecting member 200, and then the connecting member 200 is used to connect and fix the lace tension module 100 to the flexible substrate. In the production process, the connecting member 200 can be conveniently adjusted according to the actual needs of the specific wearable article, so as to form various types of lace tension assemblies to better connect and fix the corresponding wearable article.

[0052] Meanwhile, the lace tension module 100 is generally installed and fixed before the wearable article is formed. For example, when the wearable article is a shoe, the lace tension module 100 of the prior art is generally fixed on the shoe sole, and the installation and fixation of the lace tension module 100 need to be completed before the shoe upper is connected and fixed to the shoe sole. Such a structure design causes the installation and fixation to be limited and inconvenient.

[0053] In the present embodiment, the lace tension module 100 is connected to the connecting member 200, and then the mating surface 201 of the connecting member 200 is matched with the wearable article blank to connect and fix the lace tension module 100. Such a structure design can directly install and fix the lace tension assembly on the outside of the wearable article, and the installation and fixation of the lace tension assembly can be conveniently performed after the production of the wearable article blank is completed. Meanwhile, in the present embodiment, the operating portion 101 of the lace tension module 100 is arranged to be exposed outside the outer wall surface 202, which can facilitate the operation of the lace tension module 100 to realize the lace tension or slack.

[0054] Specifically, the wearable article in the embodiment can be a shoe, and the cord tightness module 100 can be fixed at the position of the shoe upper through the connecting piece 200. The shell of the cord tightness module 100 is generally made of hard plastic, which can be ABS, POM, PS, PMMA, PC, PET, PBT, PPO, etc. The material of the connecting piece 200 can be thermoplastic elastomer or silicone product. The thermoplastic elastomer can be soft PVC, K glue (BS), TPE, TPR, EVA, TPU, etc.

[0055] By setting the material of the connecting piece 200 as thermoplastic elastomer or silicone product, it has a certain deformation, which can facilitate the flexible substrate of the wearable article to be connected and fixed. Since the connecting piece 200 is soft, it can better adapt to the wearable article and deform accordingly with the slight deformation of the wearable article, thereby improving the stability of the connection and fixation with the wearable article.

[0056] In the embodiment, the direction of the docking surface 201 towards the outer wall surface 202 is defined as the installation direction. The cord tightness module 100 includes a shell 2 fixedly connected with the connecting piece 200 and a tightness execution assembly arranged in the shell 2. The tightness execution assembly is installed in the shell 2 along the installation direction. The shell 2 is provided with a limiting wall 20 limiting the outward movement of the tightness execution assembly along the installation direction.

[0057] The tightness execution assembly has a base 1, a driving mechanism 5 and a winding rope shaft 3 arranged on the base 1. The driving mechanism 5 drives the winding rope shaft 3 to rotate to tighten or loosen the cord. The base 1 has a bottom plate 15 and a connecting part 151 arranged at the edge position of the bottom plate 15.

[0058] The shell 2 has a body part 26 and an extension part 25 arranged at the edge of the body part 26. The extension part 25 is arranged in a ring shape along the body part. The connecting piece 200 is fixedly connected with the extension part 25 to realize the connection and fixation with the shell 2. The body part 26 has a receiving groove 260 with a notch facing the base 1, which is used to accommodate the driving mechanism 5 and the winding rope shaft 3. In the embodiment, the limiting wall 20 is arranged in a ring shape at one end of the body part 26 along the edge of the receiving groove 260. The extension part 25 extends outward from the one end of the body part 26 where the limiting wall 20 is arranged. The limiting wall 20 and the extension part 25 are arranged opposite to each other towards the base 1.

[0059] The limiting wall 20 is used to abut against the connecting part 151 to limit the elastic execution assembly from moving outward along the installation direction. Meanwhile, the connecting part 151 is connected and fixed with the limiting wall 20, so as to realize the installation and fixation of the elastic execution assembly to the shell 2, and then to the assembly shell formed by the shell 2 and the connecting part 200.

[0060] The existing elastic band elastic band elastic module 100 is generally arranged to fix the base 1 on the corresponding wearable product, and then the shell 2 is fixed on the base 1 to cover the corresponding driving mechanism 5 and the winding rope shaft 3. As a result, the shell 2 and the base 1 are prone to cracking in the case of unstable installation, and once the gap or crack occurs between the two, the shell 2 is prone to be separated from the base 1, thereby causing the whole elastic execution assembly to be exposed and poor in stability.

[0061] In the embodiment, the shell 2 is connected and fixed with the connecting part 200, and then the elastic execution assembly is installed and fixed on the shell 2 along the first direction. The elastic execution assembly is positioned on the shell 2 and connected and fixed with the shell 2 under the action of the limiting wall 20. In fact, the elastic execution assembly is installed and fixed along the side of the shell 2 connected and fixed with the wearable product. In the case that the shell 2 and the base 1 are not stably connected, the crack between the two also limits the elastic execution assembly between the shell 2 and the wearable product, and the elastic execution assembly will not be exposed.

[0062] The above structure requires that the connection between the shell 2 and the connecting part 200 is firm and stable. Therefore, in order to facilitate the firm connection of the shell 2 and the connecting part 200, the connecting part 200 and the shell 2 are integrally formed in the embodiment. Specifically, the connecting part 200 is injection molded on the periphery of the shell 2.

[0063] Since the connecting part 200 and the shell 2 are made of different materials, injection molding is adopted to facilitate the connection and fixation of the two. Further, in the embodiment, the connecting part 200 and the shell 2 are connected and fixed by double-color injection molding. The double-color injection molding can realize the molding of two parts at one time, which is convenient for operation. Of course, in another embodiment, the connecting part 200 and the shell 2 can also be connected and fixed by inlay injection molding. However, when the inlay injection molding is adopted, the two parts need to be molded in sequence, and the labor cost will be increased in the production process.

[0064] Further, in order to further improve the connection firmness between the two, the connecting piece 200 is injection molded on the extension 25 arranged annularly on the shell 2, and the extension 25 is formed with glue injection holes 250 combined with the connecting piece 200. The glue flowing through the glue injection holes 250 during the molding process finally forms a column to cooperate with the glue injection holes 250. The arrangement of the glue injection holes 250 increases the contact area with the shell 2 during the molding process, thereby increasing the firmness and stability of the connection between the two.

[0065] The above embodiment adopts the way of integrally molding the shell 2 and the connecting piece 200 to connect and fix the two, and in another embodiment, the connecting piece 200 and the shell 2 can also be connected and fixed in the following way. The connecting piece 200 and the shell 2 are in a split type, and the shell 2 and the connecting piece 200 are molded respectively, and then the shell 2 is installed and fixed on the connecting piece 200.

[0066] Specifically, the connecting piece 200 is formed with a fixing cavity 203 penetrating the abutting surface 201 and the outer wall surface 202, and a limiting structure 204 formed around the fixing cavity 203, the limiting structure 204 being arranged on the side of the connecting piece 200 opposite to the abutting surface 201. The shell 2 is arranged in the fixing cavity 203 along the above-mentioned installation direction. Specifically, the body part 26 on the shell 2 is arranged in the fixing cavity 203 and cooperates with the fixing cavity 203.

[0067] The extension 25 arranged annularly on the shell 2 abuts against and is fixed with the limiting structure 204 on the connecting piece 200 to realize the connection and fixation of the shell 2 and the connecting piece 200. The extension 25 cooperates with the limiting structure 204 in shape, and the extension 25 is arranged to limit the arrangement in the fixing cavity 203, and the side of the extension 25 away from the base 1 is arranged to be fixed with the limiting structure 204. The arrangement of the extension 25 and the limiting structure 204 can increase the contact area with the connecting piece 200, thereby increasing the stability of the connection between the two. In this embodiment, the shell 2 is connected and fixed to the connecting piece 200 from the installation direction only as a preferred scheme to improve the stability of the connection between the two. In another embodiment, the shell 2 can also be directly fixed and connected to the connecting piece 200 from the direction opposite to the installation direction, for example, the extension 25 of the shell 2 can be directly fixed to the outer wall surface 202, and at this time, the installation part (not shown in the figure) cooperating with the extension 25 is formed around the fixing cavity 203 on the outer wall surface 202.

[0068] In the structure, the shell 2 is installed in the above-mentioned installation direction during the connecting and fixing of the shell 2 and the connecting piece 200, and the extension part 25 is arranged on the shell 2 and abuts against the limiting mechanism 204 on the connecting piece 200 to limit the shell 2 in the installation direction, then the extension part 25 and the connecting piece 200 are connected and fixed to realize the connecting and fixing of the shell 2 and the connecting piece 200.

[0069] The structure can prevent the shell 2 from being separated from the connecting piece 200 when the shell 2 and the connecting piece 200 are not firmly connected. The body part 26 of the shell 2 passes through the fixing cavity 203 on the connecting piece 200, and the inner side wall of the fixing cavity 203 actually positions the shell 2 in four directions, and the extension part 25 and the limiting mechanism 204 can limit the shell 2 in the installation direction. After the connecting piece 200 is installed and fixed to the wearable article, the wearable article can limit the shell 2 in the direction opposite to the installation direction, and the limiting effect can prevent the shell 2 from moving in the direction opposite to the installation direction. The above-mentioned structure can more effectively realize the installation and fixing of the shell 2 and the connecting piece 200.

[0070] It should be noted that in order to ensure the connecting and fixing of the abutting surface 201 and the wearable article, the shell 2 does not protrude out of the abutting surface 201 after being positioned to the connecting piece 200. The structure requires that the first groove body on the connecting piece 200 is adapted to the extension part 25 of the shell 2, and the limiting mechanism 204 is arranged on the groove bottom of the first groove body. Correspondingly, the elastic execution assembly does not protrude out of the abutting surface 201 after being installed and fixed to the shell 2, that is, the bottom plate 15 on the base 1 does not protrude out of the abutting surface 201 after being installed and fixed. The structure requires that after the shell 2 is installed and fixed to the connecting piece 200, the limiting wall 20 arranged opposite to the connecting part 151 of the bottom plate 15 on the shell 2 is recessed relative to the plane where the abutting surface 201 is located in the installation direction to avoid the thickness of the connecting part 151. The above-mentioned structure makes the abutting surface 201 more closely combined with the wearable article, thereby improving the stability of the connection.

[0071] Specifically, as shown in FIG. 6, the base 1 is provided with a plurality of connecting pieces 200, and the shell 2 is provided with a plurality of extension parts 25 corresponding to the connecting pieces 200. Figure 10As shown in Figure 12, the base 1 also has a boss portion 14 fixed to the base plate 15 and protruding towards the housing 2. The base plate 15 also has a limiting portion 152 protruding from the inner edge of the connecting portion 151 towards the housing 2. The limiting portion 152 is connected to the boss portion 14. The housing 2 covers the outside of the boss portion 14 and the limiting portion 152, and the inner sidewall of the housing 2 is respectively in contact with the outer sidewall of the boss portion 14 and the outer sidewall of the limiting portion 152. The boss portion 14 and the limiting portion 152 facilitate the snap-fit ​​positioning of the housing 2 and the base 1, and the contact between the outer sidewall of the boss portion 14 and the inner sidewall of the limiting portion 152 and the inner sidewall of the housing 2 effectively improves the sealing performance after the housing 2 and the base 1 are fixed.

[0072] In this embodiment, to further improve the sealing performance between the housing 2 and the base plate 15 of the base 1, the limiting wall 20 and the connecting part 151 are connected and fixed by laser welding or ultrasonic welding. Laser welding or ultrasonic welding, due to their inherent welding characteristics, results in better sealing after welding, which is beneficial to the overall sealing effect of the device.

[0073] In this embodiment, the boss portion 14 has a rope-winding groove 10 with its opening facing a first direction, a rope-winding shaft through-hole 13 extending through the rope-winding groove 10 along the first direction, and a first through-hole 11 and a second through-hole 12 communicating with the rope-winding groove 10 for ropes to pass through. The first direction is the direction away from the housing 2. The housing 2 has a third through-hole 21 opposite to the first through-hole 11 and a fourth through-hole 22 opposite to the second through-hole 12.

[0074] like Figure 13 As shown, the winding shaft 3 has a toothed disc 31 rotatably mounted between the housing 2 and the boss portion 14 and a winding disc 32 coaxially arranged with the toothed disc 31. The winding disc 32 passes through the winding shaft through hole 13 along a first direction and is rotatably arranged in the winding groove 10.

[0075] The rope winding disc 32 and the toothed disc 31 are connected and fixed by a connecting part 34. After the rope winding disc 32 passes through the rope winding shaft through hole 13, the position of the connecting part 34 is exactly opposite to the inner side wall of the rope winding shaft through hole 13. The connecting part 34 of the rope winding disc 32 and the rope winding shaft through hole 13 can be set to a clearance fit so that the rope winding disc 32 can rotate around the connecting part 34.

[0076] Furthermore, to achieve a seal between the winding groove 10 and the chamber containing the gear disc 31, the winding shaft 3 also has a sealing element 35. The sealing element 35 is sleeved on the outer wall of the connecting part 34. The sealing element 35 can be a rubber ring sleeved on the outside of the connecting part 34, with the inner ring of the rubber ring tightly fitted to the connecting part 34 and the outer ring of the rubber ring tightly fitted to the inner wall of the winding shaft through hole 13. It should be noted that the setting of the sealing element 35 does not affect the rotation between the winding shaft 3 and the winding shaft through hole 13. To facilitate the installation and fixing of the sealing element 35 at the position of the connecting part 34 of the winding shaft 3, a sealing element positioning groove 341 is also provided, in which the sealing element 35 is positioned.

[0077] In this embodiment, the diameter of the toothed disc 31 is larger than the diameter of the winding disc 32, and the diameter of the toothed disc 31 is also larger than the diameter of the winding shaft through hole 13. The toothed disc 31 is rotatably mounted between the boss portion 14 and the housing 2. In this embodiment, the winding disc 32 of the winding shaft 3 is configured to pass through the winding shaft through hole 13, while the toothed disc 31 is configured to restrict its passage through the winding shaft through hole 13. During rotation, one end of the toothed disc 31 abuts against the boss portion 14, and the abutment position of the toothed disc 31 and the boss portion 14 is located exactly at the edge of the winding shaft through hole 13.

[0078] The above-described structure allows the winding shaft 3 to be directly inserted into the winding shaft through hole 13 during the manufacturing of the rope tensioning module 100, thus facilitating its installation and fixation. The winding shaft 3 with this structure is simpler and easier to install.

[0079] Furthermore, such as Figure 11 As shown in Figure 12, to reduce the friction between the gear disc 31 and the boss portion 14 during rotation, a support portion 144 extending along the protruding direction of the boss portion 14 is provided on the boss portion 14. The support portion 144 supports the gear disc 31 so that the gear disc 31 only comes into frictional contact with the support portion 144 during rotation, thereby reducing the frictional force during the rotation of the gear disc 31. Furthermore, the end of the support portion 144 that contacts the gear disc 31 can be set as an arc-shaped end to further reduce the contact area between the two, thereby achieving more efficient transmission. The support portion 144 is provided in a ring along the edge of the rope shaft through hole 13.

[0080] To better control the rotation of the winding shaft 3 and ensure its stability during rotation, the winding shaft 3 also has a rotating shaft 33 mounted on and coaxially with the gear disk 31. The rotating shaft 33 and the winding disk 32 are respectively located on opposite sides of the gear disk 31. One end of the rotating shaft 33 is fixed to the gear disk 31, and the other end of the rotating shaft 33 is rotatably mounted on the housing 2.

[0081] Specifically, the gear disc 31 has a rotating shaft positioning slot arranged opposite to the first end of the rotating shaft 33, and the shell 2 is provided with a rotating hole matched with the second end of the rotating shaft 33, the first end of the rotating shaft 33 is inserted and fixed in the rotating shaft positioning slot, and the second end of the rotating shaft 33 is rotatably installed in the rotating hole.

[0082] The rotating shaft 3 is rotatably installed in the rotating hole on the shell 2 through the rotating shaft 33 at one end, and the connecting part 34 at the middle position of the rotating shaft 3 is rotatably installed in the rotating shaft hole 13, and the rotating shaft 3 is axially limited through the abutting of the gear disc 31 and the boss part 14, so that the stability of the rotating shaft 3 during the whole rotation is realized.

[0083] The rope is threaded through the through holes on the shell 2 and the boss part 14, enters the rope winding groove 10, and is wound on the rope winding disc 32, and the driving mechanism 5 drives the rope winding disc 32 to rotate through the driving gear disc 31, so as to realize the tightening or loosening of the rope. In this embodiment, the first cavity for accommodating the rope winding disc 32 is formed by forming the rope winding groove 10 on the boss part, and the second cavity is formed between the shell 2 and the boss part 14, the first cavity and the second cavity are communicated through the rotating shaft hole 13, and the gear disc 31 and the driving mechanism 5 are arranged in the second cavity. Through the arrangement of the above structure, the rope winding disc 32 and the gear disc 31 of the driving mechanism are arranged in two cavities respectively, so as to avoid the influence of the gear disc 31 on the rope winding during transmission, and avoid the rope winding on the gear disc 31 to affect the tightening or loosening of the rope.

[0084] In addition, the arrangement of the boss part 14 supports the gear disc 31 of the rotating shaft 3, the gear disc 31 is rotatably installed between the shell 2 and the boss part 14, and the gear disc is located between the rope winding disc 32 and the shell 2. The boss part 14 actually supports the gear disc 31 to facilitate the connection with the driving mechanism 5. The arrangement of the above structure can facilitate the integrated design of the rope tightening and loosening module 100, and can reduce the volume of the whole rope tightening and loosening module 100. In the prior art, the gear disc 31 is generally driven by the gearbox 52, and the gearbox 52 is fixed on the base 1. The gearbox 52 generally has a large volume, and the output shaft of the gearbox 52 has a certain height from the base 1 after being installed on the base 1. How to effectively utilize the space generated by the height can effectively integrate the tightening and loosening module.

[0085] In this embodiment, a rope winding disc 32 is provided in the height space between the plane where the output shaft of the gearbox 52 is located and the base 1. The rope winding disc 32 effectively supports the gear disc 31 to a position at the same height as the gearbox 52, thereby facilitating the connection with the output end of the gearbox 52. The above structure avoids the waste of space caused by the large size of the gearbox 52 and is conducive to the integrated design of the entire rope tensioning module 100.

[0086] The cord winding groove 10 is provided on the boss portion 14, and the opening direction of the cord winding groove 10 points towards the wearable product. This allows for easier observation and adjustment of the cord winding process during installation, simplifying operation. In this embodiment, the cord tensioning module 100 also has a groove cover 4 provided on the base 1. The groove cover 4 is detachably installed and fixed on the base 1 to cover the cord winding groove 10. The groove cover 4 is also installed and fixed on the base 1 along the aforementioned installation direction. The side of the groove cover 4 opposite to the base 1 is used to abut against the wearable product, thus positioning the groove cover 4 between the base 1 and the wearable product. This prevents the groove cover 4 from falling off even if it becomes loosely attached to the base 1, as it remains confined between the wearable product and the base 1.

[0087] The cover 4 conceals the rope groove 10 to prevent the rope from winding out of the groove 10. The cover 4 limits the winding of the rope. The winding disc 32 on the winding shaft 3 protrudes towards the cover 4 to a position close to the cover 4. The space for accommodating the rope is actually the space enclosed by the outer wall of the winding disc 32, the inner wall of the winding groove 10, and the cover 4.

[0088] In another embodiment, the two ends of the winding shaft 3 can be rotatably installed in the rotating holes on the housing 2 and the rotating holes on the groove cover 4, respectively. The groove cover 4 is provided with rotating holes adapted to the winding disc 32. The two ends of the winding shaft 32 are respectively limited by the housing 2 and the groove cover 4, and the winding disc 32 is rotatably installed between the housing 2 and the groove cover 4. It should be noted that in this solution, the boss portion 14 does not have an axial limiting effect on the gear disc 31.

[0089] like Figure 6 As shown in Figure 12, the housing 2 covers the outside of the boss portion 14. A first sealing member 23 arranged circumferentially along the first through-hole 11 and a second sealing member 24 arranged circumferentially along the second through-hole 12 are provided between the outer wall of the boss portion 14 and the inner wall of the housing 2. In this embodiment, the boss portion 14 has a top plate 141 and a first side plate 142 and a second side plate 143 arranged on both sides of the top plate 141 and extending away from the housing 2. The rope winding shaft through hole 13 is provided on the top plate 141, and the first through-hole 11 and the second through-hole 12 are circular holes respectively provided on the first side plate 142 and the second side plate 143.

[0090] The first sealing element 23 and the second sealing element are respectively arranged circumferentially along the first through-hole 11 and the second through-hole 12. The first sealing element 23 is disposed between the first side plate 142 and the inner wall of the housing 2, and the second sealing element 24 is disposed between the second side plate 143 and the inner wall of the housing 2. The first through-hole 11 and the second through-hole 12 are used for the threading of the rope, and therefore need to be open to the outside. In order to prevent water from the outside from entering the gap between the boss 14 and the housing 2 through the first through-hole 11 or the second through-hole 12 and then entering the cavity where the drive mechanism 5 is installed and fixed, the first through-hole 11 and the second through-hole 12 need to be sealed as described above. Since there are electrical components such as batteries and motors in the cavity where the drive mechanism 5 is located, it is necessary to ensure effective waterproofing. The above structure ensures that the electrical equipment in the rope tensioning module 100 is waterproof.

[0091] In this embodiment, the first through hole 11 and the second through hole 12 are circular holes adapted to the rope. The circular holes make the rope and the through holes more compatible, thus avoiding a large and obvious gap between the rope and the through holes during the rope threading process, which would allow water to enter. In addition, the circular holes also make it easier to thread the rope.

[0092] Specifically, in this embodiment, sealing element receiving grooves 140 are respectively provided on the boss portion 14 along the circumference of the first through-hole 11 and along the circumference of the second through-hole 12. Sealing element receiving grooves 140 are also provided on the first side plate 142 and the second side plate 143 of the boss portion 14. The first sealing element 23 and the second sealing element 24 can be made of silicone. Since the boss portion 14 is made of hard plastic, the first sealing element 23 and the second sealing element 24 can be injection molded onto the boss portion 14, and the first sealing element 23 and the second sealing element 24 are respectively formed in the corresponding sealing element receiving grooves 140. To facilitate the molding of the first sealing element 23 and the second sealing element 24, the first sealing element 23, the second sealing element 24, and the boss portion 14 are molded using two-color injection molding. Two-color injection molding reduces manual labor during the molding process and simplifies the molding operation.

[0093] like Figure 14 As shown in Figure 17, the drive mechanism 5 includes a drive motor 51, a gearbox 52, and a worm gear 53 that meshes with the gear plate 31.

[0097] In the embodiment, the end of the worm 53 away from the gearbox 52 abuts against the housing 2, and the housing 2 has a worm abutting portion adapted to the worm 53. The worm 53 is used for transmission, and the toothed disc 31 provided on the winding shaft 3 is provided with a helical tooth adapted to the worm 53. The worm 53 will generate axial force during rotation to drive the worm 53 to move, and therefore the worm abutting portion is provided on the housing 2 to avoid axial movement of the worm 53. During rotation of the worm 53, one end of the worm 53 abuts against the worm abutting portion. Therefore, in order to avoid friction between the worm 53 and the abutting portion during rotation, the end of the worm 53 away from the gearbox 52 is provided with a spherical end to reduce the friction between the worm 53 and the abutting portion, thereby improving the transmission efficiency. The boss portion 14 has a worm supporting portion 145 adapted to the worm 53.

[0098] The bottom plate 15 is provided with a motor supporting table for supporting the driving motor 51 and a gearbox supporting table for supporting the positioning gearbox 52, and the gearbox supporting table has a positioning groove adapted to the gearbox housing. Since the volume of the gearbox 52 is larger than that of the driving motor 51, in order to ensure that the center position of the driving motor 51 is consistent with that of the gearbox 52, the height of the motor supporting table is higher than that of the gearbox supporting table in the embodiment. The gearbox supporting table and the motor supporting table are connected with the limiting portion 152.
