DETAILED DESCRIPTION

[0071] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.

[0072] According to a first aspect of the present application, with reference to Figs. 1 to 9, a vehicle-mounted cover plate jacking device 100 is provided, comprising a housing 110 and a jacking piece 120.

[0073] When the vehicle-mounted cover plate jacking device 100 is assembled to the vehicle 10, the jacking piece 120 serves as a specific structure for contacting and supporting the cover plate when unlocking the cover plate such as the front cover, rear cover, etc. of the vehicle 10, that is, the jacking piece 120 can be integrated into the vehicle 10 for the function of the "jacking rod" mentioned in the background section. Correspondingly, the housing 110 can be used for fixed assembly to the vehicle 10 to integrate the vehicle-mounted cover plate jacking device 100 to the vehicle 10. Furthermore, the housing 110 can be further integrated with a locking structure for unlocking the cover plate such as the front cover, rear cover, etc. of the vehicle 10, and the matching mode of the housing 110 and the locking structure is not limited here.

[0074] In the present application, referring to FIG. 1 and FIG. 2, the jacking member 120 is provided with a limiting portion 121 for limiting the range of movement of the jacking member 120 relative to the housing 110. Specifically, the jacking member 120 is in sliding connection with the housing 110. The housing 110 is provided with a limiting passage 110a in sliding cooperation with the limiting portion 121. The limiting portion 121 is slidingly arranged in the limiting passage 110a to limit the sliding of the jacking member 120 relative to the housing 110 in the first direction L1.

[0075] With the above scheme, the limiting portion 121 is arranged on the outer periphery of the jacking member 120. During the sliding of the jacking member 120 of the vehicle cover plate jacking device 100 for jacking the cover plate, the jacking member is limited in the amount of shaking during sliding by the cooperation between the limiting portion 121 and the limiting passage 110a, so that the jacking member can move more stably relative to the housing 110, thereby reducing the wear of the jacking member and improving the stability and service life of the vehicle cover plate jacking device 100 without the need for additional finishing processes and the number of parts.

[0076] For the cooperation between the limiting portion 121 of the jacking member and the limiting passage 110a to limit the movement direction of the jacking member 120 relative to the housing 110, various ways can be adopted. For example, in some embodiments, referring to FIG. 3, the housing 110 includes a passage plane 110b forming the limiting passage 110a. The passage plane 110b is in surface contact with the limiting portion 121. In a specific scheme, the passage plane 110b is parallel to the straight line of the first direction L1. That is, the surface of the limiting passage 110a in surface contact with the limiting portion 121 can be parallel to the sliding direction of the limiting member, thereby being able to guide and limit the sliding direction of the limiting member. Correspondingly, the surface of the limiting member in surface contact with the passage plane 110b can also be parallel to the straight line of the first direction L1.

[0077] The above is only an exemplary description of the specific implementation scheme of the cooperation between the limiting portion 121 and the limiting passage 110a. Various forms such as the cooperation between the sliding block and the sliding rail for the sliding block, the cooperation between the ball and the channel for the ball rolling, etc. can be adopted between the two to limit the movement direction of the jacking member 120 relative to the housing 110, which is not limited in the present application.

[0078] In some embodiments, referring to FIG. 4 and FIG. 5, the limiting portion 121 is configured as a protrusion protruding from the surface of the jacking member 120. The part of the protrusion protruding from the surface of the jacking member 120 is in surface contact with the passage plane 110b. During the sliding of the jacking member 120, the protrusion is inserted into the limiting passage 110a. In some specific embodiments, the jacking member 120 can be configured as at least a part of a cylindrical body, and the protrusion is arranged in the radial direction of the cylindrical jacking member 120.

[0079] In some embodiments, referring to FIG. 5, a plurality of protrusions are arranged around the outer periphery of the jacking piece 120. In a specific embodiment, the plurality of protrusions can be arranged in a circumferential distribution in the radial direction of the cylindrical limiting piece. By arranging a plurality of limiting portions 121 on the outer periphery of the jacking piece 120, a plurality of cooperating structures for limiting the jacking piece 120 from shaking can be formed between the shell 110 and the jacking piece 120. In this way, the jacking piece 120 is limited from shaking in more directions in space, compared with the mode in which only a single limiting portion 121 cooperates with the limiting channel 110a, the stress on the jacking piece 120 is dispersed, further reducing the wear of the jacking piece 120, and making the movement of the jacking piece 120 more stable. The specific number of protrusions is not limited in the present application. For example, in the embodiment shown in FIG. 5, the number of protrusions is 4, and 2, 3, 5, 6, etc. can also be used.

[0080] In some embodiments, referring to FIG. 3, the shell 110 is provided with a blocking portion 111. The blocking portion 111 is used to prevent the protrusion from disengaging the limiting channel 110a when sliding in the first direction L1. The blocking portion 111 is located at one end of at least one limiting channel 110a in the first direction L1, so that the blocking portion 111 separates the end surface of the shell 110 in the first direction L1 and at least the limiting channel 110a in the first direction L1. That is, at least a part of at least one limiting channel 110a in the first direction L1 is blocked by the blocking portion 111, so that after the jacking piece 120 slides relative to the shell 110 in the first direction L1, it can be hindered by the blocking portion 111. That is, the blocking portion 111 can be used to limit the sliding stroke of the jacking piece.

[0081] Referring to FIGS. 3 and 8, in a specific embodiment, a part of the limiting channel 110a can be blocked by the blocking portion 111, and a part of the limiting channel can penetrate through the shell 110 at least at one end in the first direction.

[0082] In some embodiments, referring to FIG. 3, the shell 110 is formed with a sliding channel 110c for inserting the jacking piece 120, so that at least a part of the jacking piece 120 is accommodated in the sliding channel 110c, so as to assemble the jacking piece 120 to the shell 110. The sliding channel 110c is in communication with the limiting channel 110a. The jacking piece 120 comprises a movable portion 122.

[0083] The movable part 122 is arranged at one end of the limiting part 121 along the first direction L1. At least a part of the movable part 122 is slidingly arranged in the sliding channel 110c along the first direction L1. The movable part 122 and the limiting part 121 can be integrally formed, fixedly connected, or the like. When the vehicle cover lifting device 100 is assembled on the vehicle 10, the movable part 122 can be configured to contact the cover of the vehicle 10 to support the cover. The lifting part 120 is slidingly connected to the housing 110. When the lifting part 120 moves, it has a lifting position relative to the housing 110. At the lifting position, at least a part of the movable part 122 extends out of the sliding channel 110c and contacts the cover to provide a supporting force to the cover.

[0084] In some embodiments, the vehicle cover lifting device 100 further comprises a guide 140. The guide 140 is provided with a guide part 140a mechanically connected to the lifting part 120. The lifting part 120 is provided with a guide part 123 slidingly matched with the guide part 140a. When the lifting part 120 is at the lifting position, the movable part 122 extends out of the sliding channel 110c away from one end of the limiting part 121 along the first direction L1, and the guide part 123 at least partially contacts the guide part 140a to prevent the lifting part 120 from shaking in a direction other than the first direction L1.

[0085] The cooperation of the guide part 123 and the guide part 140a further prevents the lifting part 120 from shaking when the lifting part 120 is at the lifting position, in combination with the cooperation of the limiting part 121 and the limiting channel 110a.

[0086] In some embodiments, one of the guide part 140a and the guide part 123 is configured as a guide post extending along the first direction L1, and the other is configured as a guide hole extending along the first direction L1. When the lifting part 120 is at the lifting position, the guide post is at least partially inserted into the guide hole and contacts the inner wall of the guide hole.

[0087] Referring to FIGS. 5, 6 and 7, a specific embodiment is illustrated in which the guide part 123 is configured as a guide post extending along the first direction L1, and the guide part 140a is configured as a guide hole extending along the first direction L1. Of course, the guide part 140a can also be configured as a guide post extending along the first direction L1, and the guide part 123 can be configured as a guide hole extending along the first direction L1. Through the cooperation of the guide post and the guide hole, the shaking of the lifting part 120 relative to the housing 110 is further reduced through the contact of the two.

[0088] In some embodiments, at least a portion of the guide post is located in the guide hole within the stroke of the jacking member 120 sliding relative to the housing 110. With this arrangement, the cooperation of the guide post and the guide hole further improves the stability of movement during the sliding of the jacking member 120 relative to the housing 110, and reduces the shaking and wear of the jacking member 120.

[0089] In some embodiments, the housing 110 comprises a matching portion 110d. The guide member 140 comprises a fitting portion 142.

[0090] The matching portion 110d is arranged in the sliding channel 110c. The guide member 140 is arranged in the sliding channel 110c of the housing 110, and the fitting portion 142 and the matching portion 110d are mutually fitted to limit the movement of the guide member 140 relative to the housing 110.

[0091] In a specific arrangement, referring to FIGS. 6, 7 and 8, the matching portion 110d can be configured as a protrusion arranged protruding in the first direction L1. Correspondingly, the matching portion 110d is configured as a groove formed in the inner wall of the housing 110. Through the fitting of the protrusion and the slot, the shaking of the guide member 140 relative to the housing 110 is limited, so that the guide member 140 remains stable in the sliding channel 110c, reducing the shaking between the guide member 140 and the jacking member 120, and improving the working stability of the jacking member 120.

[0092] Of course, the fitting portion 142 can also be configured as a protrusion protruding from the inner wall of the housing 110, and the matching portion 110d can be configured as a groove formed in the guide member 140 to fit the protrusion, or one of the fitting portion 142 and the matching portion 110d can be configured as a gear ring, and the other can be configured as a gear slot to fit the gear ring, and many other forms, which are not limited in the present application.

[0093] In some embodiments, the vehicle-mounted cover plate jacking device 100 further comprises an elastic member 130. The elastic member 130 is adapted to act on the jacking member 120 to make the jacking member 120 tend to be in a jacked-up position relative to the housing 110. When the jacking member 120 is in the jacked-up position, the movable portion 122 extends out of the sliding channel 110c away from one end of the limiting portion 121 in the first direction L1.

[0094] In a specific implementation, the elastic member 130 can be a spring, for example, which provides an elastic force to the jacking member 120 to provide a supporting force to the cover plate when the elastic member 130 is in the jacked-up position, and jacks up the cover plate. The elastic member 130 can also be made of a material with elasticity, such as a gasket or a metal spring, and the present application does not make specific limitations thereon. In the drawings, only some embodiments of the elastic member 130 using a spring are shown.

[0095] In some embodiments, referring to FIGS. 4 and 6, the guide 140 can be used to support the elastic member 130. The elastic member 130 is disposed in the sliding channel 110c and located between the guide 140 and the movable part 122.

[0096] As an exemplary scheme, referring to FIGS. 4 and 7, when the elastic member 130 is configured as a spring disposed in the sliding channel 110c, the guide 140 can be formed with a columnar part 141, and the spring is sleeved on the columnar part 141, so that the guide 140 can be used to support the spring and stably install the spring in the sliding channel 110c. The guide 140 can be connected with the shell 110 by integral molding or fixed connection, and the drawings of the present application only show the scheme that the guide 140 is separately provided from the shell 110.

[0097] In some embodiments, referring to FIGS. 6 and 7, the jacking part 120 is provided with an accommodating cavity 120a extending along the first direction L1, and an end of the accommodating cavity 120a along the first direction L1 is open. At least a part of the elastic member 130 is inserted into the accommodating cavity 120a, and the accommodating cavity 120a can be used to limit the elastic member 130, so as to ensure that the elastic member 130 has a stable assembly relationship with the jacking part 120. Correspondingly, the columnar part 141 can also be inserted into the accommodating cavity 120a.

[0098] For example, when the elastic member 130 is configured as a spring, the spring can be sleeved on the columnar part 141 and disposed in the accommodating cavity 120a, so as to limit the swing of the spring.

[0099] In some embodiments, the guide 140 includes a mounting part 143 located at an end of the guide 140 away from the jacking part 120, and a circumferential dimension of at least a part of the mounting part 143 is greater than a circumferential dimension of at least a part of the elastic member 130, so as to hinder the elastic member 140 from moving out of the sliding channel 110c. In a specific embodiment, the mounting part 143 can be configured to protrude from the periphery of the columnar part 141, and the mounting part 143 can be used to support the elastic member 140.

[0100] In a more specific scheme, referring to FIGS. 4 and 6, in the embodiment shown in FIGS. 4 and 6, the elastic member 140 is configured as a spring, and the mounting part 143 is disposed at an end of the guide 140 away from the jacking part 120, and a length dimension of the mounting part 143 in a direction perpendicular to the first direction L1 is regarded as a circumferential dimension of the mounting part 143. Correspondingly, an inner diameter of the spring is regarded as a circumferential dimension of the spring. By limiting the length dimension of at least a part of the mounting part 143 in a direction perpendicular to the first direction L1 to be greater than the inner diameter of the spring, the mounting part 143 can be used to block the spring from moving along the first direction to the end of the mounting part 143, so as to limit the spring in the sliding channel 110c.

[0101] In some embodiments, the guide 140 further comprises a stop portion 144. The housing 110 is further provided with an assembly channel 110e and a clearance channel 110f.

[0102] The stop portion 144 is arranged at the outer periphery of the mounting portion 143. The assembly channel 110e is used for assembling the guide 140 into the sliding channel 110c, and is communicated with one end of the sliding channel 110c along the first direction L1. The clearance channel 110f is formed at the outer periphery of the assembly channel 110e. During the process of assembling the guide 140 into the sliding channel 110c, the mounting portion 143 can be inserted into and pass through the assembly channel 110e. During the process of assembling the guide 140 into the sliding channel 110c, the stop portion 144 passes through the clearance channel 110f.

[0103] In specific embodiments, referring to FIGS. 6 and 8, the assembly channel 110e can be configured to extend along the first direction L1. The clearance channel 110f is communicated with the assembly channel 110e and located at the outer periphery of the clearance channel 110f.

[0104] In this way, the guide 140 can be assembled into the sliding channel 110c by the cooperation of the mounting portion 143 and the assembly channel 110e, and the stop portion 144 passes through the clearance channel 110f in the process. After the mounting portion 143 moves into the sliding channel 110c, the guide 140 can be placed into the sliding channel 110c by rotating the guide 140 to dislocate the stop portion 144 from the clearance channel 110f. During the use of the vehicle cover plate jacking device 100, the reaction force of the elastic member 130 on the guide 140 enables the guide 140 to be stabilized in the sliding channel 110c.

[0105] It can be understood that, in some embodiments, referring to FIG. 7, the fitting portion 142 can be arranged at one end of the stop portion 144 along the first direction, and the fitting portion 110d and the clearance channel 110f are dislocated. In this way, when the mounting portion 143 moves into the sliding channel 110c and the guide 140 is placed into the sliding channel 110c by rotating the guide 140 to dislocate the stop portion 144 from the clearance channel 110f, the fitting portion 142 can be embedded into the fitting portion 110d, so as to realize the limiting cooperation between the guide 140 and the housing 110.

[0106] Thus, the elastic member 130 provides an acting force to the guide member 140 and the jacking member 120 respectively. The guide member 140 is kept stable in the sliding channel 110c, while the jacking member 120 has a tendency to move to the jacking position, the blocking part 111 limits the jacking member 120 from being separated from the sliding channel 110c under the action of the elastic member 130, the column part 141 keeps the elastic member 130 stable between the jacking member 120 and the guide member 140, and the fitting part 142 and the matching part 110d limit the guide member 140 from shaking relative to the shell 110.

[0107] Through the cooperation of each component, it is ensured that the jacking member 120, the elastic member 130 and the guide member 140 can be stably connected and used on the shell 110, and the working stability of the vehicle-mounted cover plate jacking device 100 provided by the present application is improved.

[0108] It should be noted that the jacking member 120 relative to the shell 110 should have a storage position different from the jacking position, in which the jacking member 120 no longer jacks the cover plate, so that the cover plate can be normally closed. In a specific scheme, when the jacking member 120 is in the storage position, the spring can be configured to be in a retracted state, so that the spring can subsequently push the jacking member 120 to move to the jacking position.

[0109] The vehicle-mounted cover plate jacking device 100 provided by the present application can further include a structure for locking the jacking member 120 in the storage position, and a structure for unlocking the jacking member 120 in the storage position so that it can be subsequently moved to the jacking position. The present application does not involve improvements to these locking structures and unlocking structures, and those skilled in the art can flexibly set them according to actual use requirements, which will not be described here.

[0110] In some embodiments, referring to FIG. 3, the shell 110 includes a first shell part 112 and a second shell part 113. The sliding channel 110c is located between the space formed by the first shell part 112 and the second shell part 113, so that at least part of the jacking member 120, the elastic member 130 and the guide member 140 are located between the first shell part 112 and the second shell part 113. In actual assembly, the jacking member 120, the elastic member 130 and the guide member 140 can be assembled into the sliding channel 110c, and then the first shell part 112 and the second shell part 113 are fixed by thread connection, buckle connection, welding or other methods, and the jacking member 120, the elastic member 130 and the guide member 140 are assembled between the first shell part 112 and the second shell part 113.

[0111] In some embodiments, referring to FIG. 3, FIG. 8 and FIG. 9, the first housing part 112 and the second housing part 113 are both formed with a limiting channel 110a to cooperate with the plurality of protrusions on the jacking piece 120. The sliding channel 110c is configured to pass through the second housing part 113, and the second housing part 113 is open on one side, so that the sliding channel 110c is open on the side. The first housing part 112 is fixed on the open side of the second housing part 113 to close the sliding channel 110c.

[0112] This scheme can facilitate the observation of the assembly of each part in the sliding channel 110c when assembling the parts of the vehicle cover jacking device 100 through the open side of the second housing part 113, and facilitate the assembly of each part on the housing 110, and then use the first housing part 112 to close the open side of the second housing part 113 to protect the parts in the sliding channel 110c.

[0113] Referring to FIG. 8, on the second housing part 113, part of the limiting channel 110a can be configured to pass through the second housing part 113 in the first direction L1, that is, in some embodiments, only part of the limiting channel 110a on the housing 110 can be blocked by the blocking part 111 in the first direction L1.

[0114] In some embodiments, referring to FIG. 3, one of the first housing part 112 and the second housing part 113 is provided with a buckle 114. The other of the first housing part 112 and the second housing part 113 is provided with a clamping groove 115. The buckle 114 and the clamping groove 115 are engaged with each other to form a fixed connection between the first housing part 112 and the second housing part 113. In the drawings, only the specific implementation scheme of forming the clamping groove 115 on the first housing part 112 and the buckle 114 on the second housing part 113 is shown. The number of buckles 114 and clamping grooves 115 is not limited here. Through the mutual buckling of the buckle 114 and the clamping groove 115, the fixation of the first housing part 112 and the second housing part 113 can be conveniently completed.

[0115] In some embodiments, referring to FIGS. 3 and 9, the first housing portion 112 is provided with a combination portion 116 inserted into the sliding channel 110c from one side of the second housing portion 113, which is used to limit the movement of the guide piece 140 in the sliding channel 110c. In a specific scheme, the combination portion 116 is located between the guide piece 140 and the second housing portion 113 in the first direction L1, limiting the movement of the guide piece 140 in the first direction L1 to prevent the guide piece 140 from being detached from the sliding channel 110c. In a more specific scheme, the guide piece 140 is provided with a matching groove 140b, and the combination portion 116 is inserted into the matching groove 140b, which can limit the rotation of the guide piece 140, reduce its shaking, and further ensure the stability of the guide piece 140 in the sliding channel 110c. Moreover, limiting the shaking of the guide piece 140 can also reduce the displacement of the guide piece 140 relative to the jacking piece 120, which can avoid the guide piece 140 generating a force on the jacking piece 120 other than the first direction L1 due to the change in the relative position of the two, and therefore, the mutual embedding of the combination portion 116 and the matching groove 140b can further ensure that the jacking piece 120 is not damaged.

[0116] According to a second aspect of the present application, referring to FIG. 10, a vehicle 10 is provided, which comprises the aforementioned vehicle-mounted cover plate jacking device 100.
