[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present application. As used in the specification and appended claims of the present application, the singular expressions "one", "a kind of", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear indication to the contrary in the context.

[0055] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0056] The multiple involved in the embodiments of the present application means greater than or equal to two. It should be noted that in the description of the embodiments of the present application, the words "first", "second", etc. are only used for the purpose of distinguishing the description, and cannot be understood as indicating or implying relative importance, nor can they be understood as indicating or implying an order.

[0057] like Figure 1-Figure 23As shown, the tailgate opening and closing system provided by the embodiment of the present application includes: a two-way hinge assembly 100 and a hinge lock 200. The two-way hinge assembly 100 is used to connect the tailgate 500 and the vehicle body 600, and the two-way hinge assembly 100 can make the tailgate 500 rotate relative to the vehicle body 600 in at least two directions; there are at least two hinge locks 200, and the hinge locks 200 are used to connect the tailgate 500 and the vehicle body 600, and the hinge locks 200 have a first state that separates the tailgate 500 from the vehicle body 600, and a second state that rotates the tailgate 500 relative to the vehicle body 600 when the tailgate 500 and the vehicle body 600 are locked; the two-way hinge assembly 100 and the hinge locks 200 are connected to the four corners of the tailgate 500 and the vehicle body 600 in sequence, and the hinge locks 200 are adjacent to the two-way hinge assembly 100. In this way, when the hinge lock 200 on any side adjacent to the two-way hinge assembly 100 is locked and the other hinge locks 200 are unlocked, the tailgate 500 can be flipped relative to the vehicle body 600 along the line connecting the two-way hinge assembly 100 and the locked hinge lock 200, so that the tailgate 500 can be opened in at least two directions relative to the vehicle body 600. According to the specific installation position of the two-way hinge assembly 100, the tailgate 500 can be rotated to one side to open and flipped downward to open, or the tailgate 500 can be rotated to one side to open and flipped upward to open, so that at least two opening directions of the tailgate 500 can be provided during the process of transporting goods, thereby reducing the inconvenience of transporting goods caused by opening the tailgate 500.

[0058] In some embodiments, the bidirectional hinge assembly 100 is located at the top of the tailgate 500, so that the tailgate 500 can be opened in two ways: flipped upward relative to the vehicle body 600 and opened to one side, providing multiple options for the opening direction of the tailgate 500.

[0059] In order to provide a larger space for loading and unloading goods after the tailgate 500 is opened, the two-way hinge assembly 100 is located at the bottom of the tailgate 500. In this way, the tailgate 500 can be opened relative to the vehicle body 600 in two ways: flipping downward and opening to one side. When the tailgate 500 is opened to one side, the staff can get closer to the vehicle body, reducing the inconvenience of carrying goods caused by opening the tailgate 500.

[0060] When the tailgate 500 can achieve two opening directions, the locking structure diagonally distributed with the two-way hinge assembly 100 needs to remain unlocked during the opening of the tailgate 500. In order to save costs, the tailgate opening and closing system provided in the embodiment of the present application also includes a door lock 300. The door lock 300 is used to lock or unlock the tailgate 500 and the vehicle body 600. There are two hinge locks 200 and they are adjacent to the two-way hinge assembly 100, so that the door lock 300, one of the two hinge locks 200, the two-way hinge assembly 100 and the other of the two hinge locks 200 are distributed in sequence along the four corners of the tailgate 500.

[0061] For example, Fig.16 and Fig. 20 As shown in the figure, the two-way hinge assembly 100 is located at the lower right corner of the tailgate 500, the two hinge locks 200 are respectively located at the lower left corner and the upper right corner of the tailgate 500, and the door lock 300 is located at the upper left corner of the tailgate 500. In this way, when the door lock 300 and the hinge lock 200 located at the upper right corner of the tailgate 500 are unlocked, as shown in FIG. Fig.16 As shown, the tailgate 500 can be opened backwards; when the door lock 300 and the hinge lock 200 located at the lower left corner of the tailgate 500 are unlocked, as shown Fig. 20 As shown, the tailgate 500 can be opened to the right, so that the staff can be closer to the vehicle body 600 and can carry the goods more conveniently, thereby reducing the inconvenience of carrying the goods caused by the opening of the tailgate 500.

[0062] In some embodiments, the door lock 300 is a mechanical lock and the hinge lock 200 is a mechanical hinge lock, so that the door lock 300 can be unlocked by manual operation, which saves costs.

[0063] In some other embodiments, the door lock 300 is an electronic lock, and the hinge lock 200 is an electrically controlled hinge lock. Specifically, Figure 1 As shown, the first control key 410 and the second control key 420 are also included. The first control key 410, the second control key 420, the electronic lock and the electric hinge lock are all electrically connected to the control system of the car. In this way, by operating the first control key 410 or the second control key 420, the door lock 300 and the corresponding hinge lock 200 can be opened, so that the tailgate 500 can be opened by electric control, which saves the operating procedures of the staff and improves the convenience of the tailgate 500 opening process.

[0064] In some embodiments, Fig.16 As shown, the first control key 410 and the second control key 420 are located on the tailgate 500 , so that the staff who need to move the goods can directly operate the keys to select the opening direction of the tailgate 500 .

[0065] In some other embodiments, the first control key 410 and the second control key 420 may also be located at the driving seat in the vehicle, or remotely controlled by buttons on the car key, which can provide a variety of control options and further increase the convenience of operation. This embodiment of the present application is not limited to this.

[0066] It should be noted that the door lock 300 can be selected from a variety of electronic locks that can be controlled by the vehicle control system, such as an electric reed door lock, an electric card door lock, etc., which is not limited in the embodiment of the present application.

[0067] The bidirectional hinge assembly 100 includes a fixed part and a rotating part. The fixed part is used to be fixedly connected to the vehicle body 600 , and the rotating part is used to be fixedly connected to the tailgate 500 . The rotating part and the fixed part can rotate and cooperate in at least two directions.

[0068] like Figure 2-Figure 5 As shown, the fixing member includes an upper cover 110 and a lower cover 120 that are detachably fixedly connected, the upper cover 110 is provided with a first through hole 111, and the lower cover 120 is provided with a second through hole 121, so that the threaded fastener can pass through the first through hole 111 and the second through hole 121 to fix the fixing member to the vehicle body 600. Fig.18 , Fig. 22 As shown, in order to facilitate the installation of the fixing parts, a mounting platform is provided on the vehicle body 600, so that the fixing parts can be installed on the mounting platform through threaded fasteners. In order to ensure the normal operation of the two-way hinge assembly 100, the mounting platform has a slope that meets the installation requirements. The angle of the slope can be adjusted according to actual conditions, and the embodiment of the present application does not limit this.

[0069] In order to facilitate the installation of the fixing member, one of the upper cover 110 and the lower cover 120 further includes a positioning member, through which the upper cover 110 and the lower cover 120 can be positioned so that the first through hole 111 and the second through hole 121 can correspond to each other, thereby facilitating the installation of the fixing member.

[0070] For example, Figure 2-Figure 5 As shown, the lower cover 120 is provided with a bending plate 123, and a plurality of the bending plates 123 are arranged along the circumference of the lower cover 120. In this way, after the upper cover 110 is placed on the top surface of the lower cover 120, by bending the bending plate 123 on the top surface of the upper cover 110, the upper cover 110 and the lower cover 120 can be relatively fixed, and the first through hole 111 and the second through hole 121 are made opposite to each other, which is convenient for threaded fasteners to fix the fixing part and the vehicle body 600, thereby improving the installation efficiency of the two-way hinge assembly 100.

[0071] The rotating member includes a spherical body 131 and a connecting rod 132 that are fixedly connected, and a connecting plate 150 for connecting the tail fence plate 500 and the connecting rod 132. The connecting plate 150 is provided with a third through hole 151. Fig.18 , Fig. 22 As shown, the threaded fastener can pass through the third through hole 151 to fix the connecting plate 150 to the tailgate 500 , so that the rotating member can be fixedly connected to the tailgate 500 .

[0072] In order to enable the rotating part to rotate relative to the fixed part, Figure 2-Figure 5 As shown, the upper cover 110 is provided with a receiving hole 112 for the connecting rod 132 to pass through, and the lower cover 120 is provided with a receiving groove 122. The receiving hole 112 and the receiving groove 122 form a receiving space capable of receiving the sphere 131, so that the sphere 131 can rotate in the receiving space, and the sphere 131 is limited in the receiving space, so that the sphere 131 is relatively fixed in the receiving space in its radial direction, so that the rotating part can rotate relative to the fixed part without being separated from the fixed part, so as to realize that the tailgate 500 can be flipped open relative to the vehicle body 600 when it is connected to the vehicle body 600.

[0073] During the rotation of the ball 131 in the accommodation space, in order to ensure that the ball 131 does not leave the accommodation space, the diameter of the opening of the accommodation hole 112 in the upper cover 110 should be smaller than the diameter of the ball 131, which results in a smaller angle range for the ball 131 to rotate in the accommodation space. However, in order to facilitate the transportation of goods, the tailgate 500 needs to be able to open a sufficient angle relative to the vehicle body 600, so that the rotating part can rotate at a larger angle relative to the fixed part, such as Figure 2-Figure 5 As shown, the bidirectional hinge assembly 100 further includes a bushing 140, which is mounted on the sphere 131, and the bushing 140 is rotatably matched with the accommodating space and the sphere 131. Figure 3 As shown, when the tailgate 500 is opened backwards, due to the presence of the bushing 140, the opening diameter of the accommodating hole 112 of the upper cover 110 can be increased, so that the sphere 131 can rotate while driving the bushing 140 to rotate, thereby increasing the rotation range of the sphere 131 and allowing the tailgate 500 to open to a larger angle, further reducing the inconvenience in handling goods caused by the opening of the tailgate 500.

[0074] In some embodiments, the bushing 140 is an integrated structure and can be pre-assembled with the ball 131 , thereby increasing the strength of the bushing 140 and extending the service life of the bidirectional hinge assembly 100 .

[0075] In some other embodiments, such as Figure 5 As shown, the bushing 140 includes a first bushing 141 and a second bushing 142 that are fixed by snapping together. In this way, during the installation process, the bushing 140 and the ball 131 can be installed by snapping together the first bushing 141 and the second bushing 142, thereby improving the convenience of installing the bidirectional hinge assembly 100.

[0076] like Figure 4As shown, when the tailgate 500 is opened to one side, the connecting plate 150 can rotate relative to the fixing member following the tailgate 500. In some embodiments, the connecting plate 150 is fixedly connected to the connecting rod 132, and the connecting plate 150 is rotated to one side by the rotation of the ball 131, so that the tailgate 500 can be opened to one side.

[0077] In some other embodiments, the connecting plate 150 is rotatably matched with the connecting rod 132, the connecting plate 150 rotates relative to the connecting rod 132 based on the axial direction of the connecting rod 132, and the connecting plate 150 is relatively fixed to the connecting rod 132 in the radial direction of the connecting rod 132 and along the axial direction of the connecting rod 132. In this way, the tailgate 500 can be opened to one side by the rotation of the connecting plate 150 relative to the connecting rod 132, and at the same time, the tailgate 500 can be opened to one side at a larger angle by the rotation of the ball 131, further reducing the inconvenience of carrying goods caused by the opening of the tailgate 500.

[0078] like Figure 6-Figure 10 As shown, the hinge lock 200 includes a lock buckle 210 and a hinge lock body 220 that can be locked with each other. The lock buckle 210 includes a fixedly connected mounting plate 211 and a locking rod 212. One of the mounting plate 211 and the hinge lock body 220 is fixedly connected to the vehicle body 600, and the other is fixedly connected to the tailgate 500. For example, Figure 15-Figure 22 As shown, the mounting plate 211 is fixedly connected to the vehicle body 600, and the hinge lock body 220 is fixedly connected to the tailgate.

[0079] In the first state, the hinge lock body 220 is separated from the locking rod 212 so that the tailgate 500 can be separated from the vehicle body 600; in the second state, the hinge lock body 220 and the locking rod 212 are locked with each other in the radial direction of the locking rod 212, and the hinge lock body 220 and the locking rod 212 can rotate with the axis of the locking rod 212 as the center, so that the tailgate 500 can rotate relative to the vehicle body 600 when locked with the vehicle body 600.

[0080] In some embodiments, Figure 6-Figure 8 As shown, the hinge lock body 220 includes a ratchet 221, which can limit the locking rod 212 from being separated from the hinge lock body 220 along its radial direction. Fig.11As shown, the ratchet 221 includes a first ratchet 2211 and a second ratchet 2212 that are engaged with each other. The first ratchet 2211 limits the second ratchet 2212 from rotating clockwise, so that the second ratchet 2212 locks the locking rod 212 inside the hinge lock body 220; when unlocking is required, the electrical signal released by the control system of the car drives the unlocking motor in the hinge lock body 220 to rotate the first ratchet 2211 counterclockwise to release the second ratchet 2212, so that the second ratchet 2212 rotates clockwise under the action of the spring force, so that the second ratchet 2212 can push the locking rod 212 to separate from the hinge lock body 220 in the direction shown in the figure, so as to unlock the hinge lock 200.

[0081] In some other embodiments, the hinge lock body 220 and the locking rod 212 may also be locked by electromagnetic cooperation or other electrically controlled locking methods, which is not limited in the embodiments of the present application.

[0082] In order to ensure that the hinge lock body 220 and the locking rod 212 can rotate and cooperate with each other when the hinge lock body 220 and the locking rod 212 are locked, Fig.11 As shown, the locking rod 212 is covered with a rotating layer 2121, the locking rod 212 and the rotating layer 2121 are rotationally matched, and the hinge lock body 220 and the rotating layer 2121 are locked to achieve rotation between the locking rod 212 and the hinge lock body 220 when locked.

[0083] In some embodiments, Fig.13 As shown, the rotating layer 2121 is a rotating bracket, and the rotation between the locking rod 212 and the rotating bracket is achieved through a small friction force between the rotating bracket and the locking rod 212.
